Dealing with Moral Issues in Health Care Assignment
Dealing with Moral Issues in Health Care - Assignment Example As the report stressesà there was a belief that spirits cure diseases, which are caused as a result of divine punishment. Although, this concept is no longer accepted in the modern world, some of the religious beliefs and ideologies are observed to still hamper the moral issues in health care, wherein spirituality persists in contrast to morality. Some Muslim patients still convey strong religious or cultural issues about ââ¬Ëmodestyââ¬â¢, especially when being treated by the opposite sex, as commonly observed among the followers of Buddhism, Hinduism and Judaism.à From the discussion it is clear thatà a major proportion of Buddhists and Hindus can be observed as very rigidly ââ¬Ëvegetarianââ¬â¢. For such patients, medicines produced from animals, is very much likely to cause problems, owing to the fact that such practices might be considered contradictory to their religious beliefs. The ââ¬Ëdietaryââ¬â¢ problem is also very much likely for Muslims and Jews, a s they refuse to accept pork or gelatin in their medicines. The Muslim patients may also question about alcohol based medicines and hand-rubs, which is strictly prohibited in their religion.à Suggestively, religious concepts, hampering the moral issues in health care can be minimized or even made negligible by adapting certain changes in actions and thoughts of patients, motivating them to become more flexible and rational towards medication.à Social media networks can also be major tool to generate awareness among patients and deal with the above discussed moral issues.

Gas Chromatography Mass Spectrometry in Food Analysis
Gas Chromatography Mass Spectrometry in Food Analysis The food is a highly complex nature which consisted organic and inorganic components. It is undeniable that Gas Chromatography (GC) has many usage and application. It is also noted that gas chromatography has a wide range of applications especially in the food aspect analysis which includes composition of food, components of aroma and flavor, food additives, natural products etc. The aim of this section is to provide an overview of gas chromatography mass spectrometry in food analysis due to the arising of awareness on nutrition and health concern. Review in Journal of Food Science: Comparison of the Flavor Chemistry and Flavor Stability of Mozzarella and Cheddar Wheys The stability of flavor of fresh and stored liquid Cheddar and Mozzarella wheys are being compared. The flavors profiling is being run by sensory analysis whereas extraction of volatile components are followed by characterization by solvent extraction. This is continued with gas chromatography-mass spectroscopy. The application of this research is for further understanding of the flavor of the raw materials which will greatly help manufacturers to have optimization of quality by identifying the methods. Application Gas chromatography modeled 690N Agilent was used with 5973 inert mass detector (MSD) for the analysis of the extraction of solvents. Fused silica capillary column as sued for the separation which is Rtx-5ms 30-m length Ãâ" 0.25-mm inner dia Ãâ" 0.25-à µm df . 1ml/min of a constant flow rate of helium is used. Besides, the temperature of the oven was set beginning at 40à ºC for 3min, increased of 10à ºC /min until 90à ºC, then 5à ºC/min to 200à ºC and holding time of 10 min, continued with an increase of 20à ºC/min, finally with 250à ºC and a holding time with 10min. The inert mass selector detector held for 3 min for the solvent delay and parameters was scanned by inert mass selector detection which was set from 35 to 300 m/z. 2à µL of each extract was injected in the splitless mode. The samples were duplicated for duplication analyses for further accuracy. The 2 main whey types of Cheddar and Mozzarella differences were the intensity of the compounds which based on an increased or decreased after storage by fat separation. Based on the results, it is known that the fat separation resulted in decreased concentration of lipid oxidation products by Gas chromatography mass spectroscopy. It is concluded that flavor profiles of the 2 types of samples were different from each other and gas chromatography mass spectroscopy volatile recorded the differences between the selected volatile compounds in each whey sample. The objective was fulfilled as it is proven that Cheddar whey is more easily to undergo oxidation than Mozzarella whey. Review in Journal of Food Science: Sensory and Physiochemical Characterization of Juices Made with Pomegranate and Blueberries, Blackberries or Raspberries The study of quality parameters of 1 commercial pomegranate juice mixed with different 5 concentration of blueberry, blackberry or raspberry juices. Solid phase microextraction ââ¬â gas chromatography mass spectroscopy was used for the determination of volatile components which present in the mixtures in order to perceive the differences of aroma of the juices. The relationship between consumers and instrumental data was studied for the determination of innovation of designed juices by conducting a consumer study. This application of this research is to help juice industry to further understand the consumerââ¬â¢s preferences for the blended juices of pomegranate. Application Gas chromatography mass spectrometry modeled GC CP3800 Varian was used for the separation, identification, and qualification of the volatile components of the mixtures. The analytes was injected to the injection port of the gas chromatography at 250à º C during splitless mode of 5 min. The gas chromatography mass spectroscopy used RTx-5MS column , 30 m Ãâ" 0.25mm Ãâ" 0.25à µm film thickness which composed of 5% dephenil/ 95% dimethyl polisiloxane. Then, the temperature of the column was set beginning at 40à º C and was increased 280à º C at 8à ºC/ min with a holding time of 10 min. The components identified in the mixtures used Kovats indices and mass spectra analytical methods. There are 40 volatile compounds found in the juices. The most common compounds in the 3 berry juices were ethyl acetate, 3-methylbutanal, hexanal and linalool. In the nutshell, it is found out that blueberry juice is preferred by consumers with the mixtures of pomegranate juice. Review in Journal of Food Science Iron-Lactoferrin Complex Reduces Iron ââ¬âCatalyzed Off ââ¬âflavour Formation in Powdered Milk with Added Fish Oil Iron-lactoferrin complex is beneficial for dietary iron supplement but the effect has not been reported that iron-catalyzed off flavors in food products contained lipids. Therefore, the effects of iron-lactoferrin on off flavors were studied with the additional of fish oil. Compounds which have undergone oxidation such as pentanal, hexanal, heptanal etc were less developed in the powdered milk that contained iron-lactoferrin rather in iron(II) sulphate. The application of this research results proves and shows that iron-lactoferrin complex is beneficial for continuous fortification of foods with iron and fish oils. This is because there is a reduction of the formation of iron catalyzed off flavors in powdered milk fortified with fish oil. Application Gas Chromatography modeled 6890 Agilent with a mass selective detector of 5973 Agilent were used to performed analysis of volatile headspace compounds from the sample. The separations of volatiles were separated on DB-5 capillary column with measurement of 0.32mm i.d. Ãâ" 60m, 0.52à µm of film thickness in the operations with a constant flow of 2.4mL/min. As for the temperature, it was set initially at 37à º C was increased to 190à º C, at rate of 4à º C/min and then to 280à º C at 40à ºC/min which the holding time is 8 min. In conclusion, iron-lactoferrin was proven by the measurements of headspace gas chromatography mass spectroscopy reduce the oxidation of flavor and metallic taste of powder milk enriched with fish oil during storage and processing. Review in Journal of Food Science Comprehensive Assessment of Antioxidant Activity of Essential Oils It had been known the unique ability of essential oils was studied due to their special properties that act as antioxidants. The 20 samples with oil that have EC50, which is less than 300à µg/mL were analyzed by gas spectrometry mass spectrometry and many more. The application of the founded results will enhance the understanding of spices which contains essential oil may inhibit the oxidative damage, lipid oxidation and increase the level of antioxidant activity of the product. Application Gas chromatography modeled 580A Hewlett Packard Series II were used to analyze the essential oil with mass selective detector and autosampler. The column used with a measurement of 30m, 0.25mmID with 0.5à µm film thickness at the constant flow rate of 1.0mL/min and pressure of 20.0 psi. The temperature injector is 250à º C, the beginning of oven temperature was 120à º C and was increased to 10.0 à º C/min to 180à º C. Once the temperature reached 180à º C and rate was changed to 3.0à º C/min till the temperature reached 240à º C and holding time was 5 min. The total run time was 31.0 min. After running gas chromatography mass spectrometry, the chemical compounds in relation to antioxidant activities were known. It is based on the retention indices, co-chromatography with standards etc. The analysis of gas chromatography mass spectrometry also shows basil oils that are rich in linalool and geraniol. The confirmation of the indication of phenolic terpenes in antioxidant oil was also done. It can be concluded that phenolic terpenes is the major contribution to the most effective oils. Furthermore, several sesquoterpens are shown to have the ability to scavage free radicals. . Review in Journal of Food Science Change of Volatile Compounds in Fresh Fish Meat during Ice Storage This study is to determine the changes of volatile compound in fresh fish such as sardine, jack mackerel, bluefin tuna etc. during 3-4 d of ice storage by using headspace solid phase micro extraction gas chromatography mass spectrometry. Based on the result, it is revealed that there is an increased of aldehyde and alcohols in jack mackerel and chub mackerel followed by skipjack and red seabream during storage. The purpose of this research is to study the results to apply in inhibiting fishy off-flavor products. It is the lipid oxidation that change the fresh fish flavor so it is crucial for the prevention of oxidation of lipid. Application Modeled Turbo Mass system Perkin Elmer was used to analyze the extracted volatile compounds. The column used for separation with a measurement of 60m Ãâ" 0.25 mm i.d., 0.25 à µm film thickness. Preheating the column to 40à ° C and it was increased to 260à ° C at 5à ° C /min. The carrier gas used was helium with a constant head pressure at 20 psi. Moreover, the temperature of the injector is 250à ° C and splitless mode is change to split mode (50:1) at 0.3 min after the injection. The gas chromatography mass spectrometry identified 32 compounds of the red and white flesh fish and shows no apparent peaks during storage. The detection of the volatile compounds dependent of the storage time. Therefore, the various changes on the fish flavors might be depending on the content of lipids, lipoxygenase activity and fishââ¬â¢s redox potential. (Taiko Miyasaki, 2011) (Hiroshi M.

The Applications of ICT- Shopping :: ICT Essays
The Applications of ICT- Shopping Supermarkets and checkouts. The advancements in the technological world have allowed supermarket chains and other national stores to quickly dominate the market and are driving out the concept of the ââ¬Ëlocal storesââ¬â¢. This surge in the market has seen shares rise and profits bulge with the three main contenders in mind being Sainsburys, Safeways and Tescos who now serve the whole of the UK between them and are the household names of the shopping world. The ICT input to these businesses is vital in that it provides speedy service; controls stock levels and will even allow bank balance transfers to be carried out with minimal difficulty or technical experience. The ââ¬Ëtillââ¬â¢, arguably a simple word has been given several names in the information technology world depending on the tasks, which the one in question can perform. à · POS- Point Of Sale terminal (ordinary checkout) à · EPOS- Electronic Point Of Sale terminal (Checkout connected to a computer data base using a laser scanner to read bar codes). à · EFTPOS- Electronic Funds Transfer Point Of Sale (the same as EPOS with the capability to make transfers for customers to pay for goods via credit or debit cards. The checkout uses the ICC (integrated chip card which is very popular on the continent) or Magnetic strip on the card to request the information of the user to see whether or not they are eligible to make an EFT. The magnetic strip can only hold a limited amount of data such that an 11 or so digit code is sufficient to recall the same data from the bank servers. The ICC however can hold much more information and is much harder to copy or have data changed by criminals or hackers. The checkouts used in modern supermarket chains are all capable of EFT and are therefore all considered EFTPOS. In the next few years checkouts or ââ¬Ëtillsââ¬â¢ in all retail shops will use the ICC Barcodes The goods found in supermarkets are labelled with barcodes used to identify specific items on a central database. When the good is scanned a request is sent from the checkout to this main database where the request is handled and the appropriate information returned to that terminal and the correct amount reduced from the stock of that item. The bar codes are formed of lines of different widths and as each line represents a number the resulting code is the information sent to the main computer.

Group Manuscript
Bacterial cells are a common choice for in vivo replication of DNA of interest, and in this study, the heat shock method was employed for bacterial transformation. Plasmids, which are DNA molecules themselves, were used as expression vectors for the DNA of interest, the GAP gene. Because only transformed cells exhibit antibiotic resistance, trans armed cells survived on plates containing inclining. Only those cells that took up plasmid s containing the GAP gene fluoresced in IV light.By restriction enzyme analysis and gel electro prophesiers, the relationship between genotype and phenotype was observed using isolated p zamias from the bacteria. Because the presence of the GAP gene codes for fluorescence, it is expected t hat a genotype coding for the protein would express the glowing phenotype. Regular action of GAP gene expression was observed in samples that were grown with rabbinate, inimical in, and varying amounts Of glucose. Our results Suggest that the presence Of glucose in t he s rounding environment inhibited transcription from the rabbinate bad promoter. Age 3 INTRODUCTION This study examined the transcriptional regulation Of the rabbinate Oberon pr emoted found in Escherichia coli (E. Coli). To facilitate this study, the Green Fluorescence t protein (GAP) was utilized as a reporter gene with the rabbinate promoter. The KEEP gene w as 772 base pairs (BP) long and was extracted from Quarrel Victoria. This gene was implanted into plasmids, which were inserted into the E. Coli through bacterial transformation (3). In order to obtain enough copies of these DNA samples in a reasonable ammo NT of time, two methods can be used.The first is considered in vitro , or in glass, (such as a test tube) and is known as polymerase chain reaction. This method, in which a machine heats t he DNA sample ND Tag polymerase clones the DNA, is expensive and less convenient, so it is not always used. The other method is In Vivo , or in life, and is called transformation. This method was used in this experiment by shocking E. Coli bacteria with heat in order for them to take in plasmids that were transformed to contain the GAP gene. Not all bacteria were transformed, and not all transformed bacteria contained the GAP gene.To differentiate between transformed and n untransformed bacteria, they were grown on inclining, as the transformed bacteria were rest assistant to impact Olin but the untransformed bacteria were killed by it. The plasmids with and with out the GAP gene were differentiated by visualization under IV light (4). The genotype of the remaining plasmids, both transformed and nontransparent med, were then tested to determine the relationship between the genotype, or plasmid c imposition, and phenotype, or presence of fluorescence.The plasmids were removed from the e bacteria, with some samples left whole as controls and others cut into pieces by restriction enzymes. In this case, doll, originating from Hemophilia influenza , was the enzyme use d to cut the plasmids Page 4 at their respective Hind doll sites, where the GAP gene would have been inserted. This was done to determine whether or not the KEEP gene was taken in by the plasmids when it was electrophoresis, as the difference in size of the pieces was observed in the gag arose gel (4).Even though a transformed bacterium may have had the GAP gene in its insert Ted plasmid, it needed the promoter bad (consisting of genes Arab, area, and award) and t he GAP gene in the right direction and position in order for the bacterium to have the potent al for fluorescence. It may still not have fluoresced if there was not enough rabbinate present for the bad promoter to run, or if a high concentration of glucose inside the cell was present to rep as the bad promoter.With all the necessary genetic coding for fluorescence, the amount that was visible depended on the amount of glucose present, as no glucose caused it to floorer see brightly, and a low concentration made it glow dul ly (4). Each step of this experiment was vital in analyzing the transcriptional regulate on of the rabbinate Oberon promoter. Through bacterial transformation, recombinant DNA and cloning methods were used in order to insert the GAP gene into the plasmid.The pellet of cells was then resume need using a pipette and vortex mixer. This allows for a XX concentration to be obtained. After spreading, the four plates were incubated upside down (overnight at 370 C) in a microbial incubator. Following incubation each plate was placed upside down n a IV box and photographed. Restriction Analysis In restriction analysis, two restriction enzyme digestion reactions (one uncut b Y enzyme, one cut by enzyme) occurred for each of the two DNA samples (nonresistant and non page 6 fluorescent, resistant and inflorescent, and resistant and fluorescent).For the uncut samples, components were added in the following order: Pl XIX Buffer ( supplied by environment by life technologiesâ⬠ââ¬Ë containi ng: 100 mm Trisect, pH 7. 5 100 mm Magical mm Theoretical 500 mm Nasal), 1 Pl Water, and 5 Pl DNA For the uncut samples, components were e added in the allowing order: Pl XIX Buffer, Pl Water, pi DNA, and III Handbill NZ. (sup plied by invitation by life technologiesâ⬠â⬠). After all components were added they were mixed by overexerting and collected at the bottom of the tubes by using the microelectronic gem The tubes were then incubated for 30 minutes at 37 co.Following incubation, Pl of XIX loading g buffer (1% (w/v) SD (sodium decoded sulfate) 50% (v/v) glycerol 0. 05% (w/ v) bronchiole blue) was added to each tube. The samples were mixed by overexerting and collected at the e bottom of the tubes using the microelectronic- Agrees gel electrophoresis was prepared by ding Pl of 1 KGB plus ladder ( supplied by environment by life technologiesâ⬠â⬠) into the first and final well. 12. Pl of each sample was then loaded into remaining wells on the gel and the electro prioress was run for 1 hour at 1 VIVO.The gels were then placed in a IV box and photographed. Using the photo of the gel, the genotypes of each sample were verified. This was done by finding the size of fragments through comparison with the DNA standard ladder. Gene Expression TO allow for observation Of phenotypes gene expression, bacteria were transfer erred to three types of media: inducing, introducing, and repressing. Five plates were used: LB,'Amp, LB/Marry, LB/Amp/AR/Glue 0. 2%, LB/Amp/AR/Glue 0. 5%, LB/ Amp/AR/Glue 2% (xx).On each plate, bacteria with empty plasmids and therefore no GAP gene for flour essence were spread on one half, and bacteria with plasmids containing the GAP insert were e transferred to the Page 7 other. Both of these types of cells came from a master plate. Using a sterile to toothpick, each type of bacteria was patched in the appropriate area of each plate. GAP+ bacteria were patched in a ââ¬Å"+â⬠shape, while GAP bacteria were patched in a shap e. Plates were labeled properly and Leary and were placed Poseidon in a ICC incubator overnight.Plates were e observed for fluorescent bacteria on the IV transformational box after 24 hours, after 72 h ours, and again after 96 hours. Page 8 RESULTS Bacterial Transformation In order to investigate GAP gene expression, it was first necessary to obtain co pies of the DNA of interest through bacterial transformation, which allowed for plasmid ( and sometimes GAP) uptake by numerous bacterium. Phenotypes results from this procedure can suggest possible genotypes. Transformation plates that were prepared after heat shoo KC transformation can be Seen in Figure 2.Individual colonies were visible on each AMP+ plate, while a lawn of bacteria had formed on the AMP plate and individual colonies were not discern enable. Under IV light, fluorescence was observed in those colonies expressing the GAP gene. If guru E highlights the difference observed between glowing and knowing bacterial colonies. The fraction of colonies that appear fluorescent and are assumed to be GAP+ is noted in Table e 1 along with complete results of this bacterial transformation (4).Structural Analysis by Restriction Analysis and Gel Electrophoresis TO confirm the structure Of DNA plasmid genotypes, samples were run through h gel electrophoresis after being treated with a restriction enzyme specific for cleave ins the gene of interest (GAP). Standards were run along with each of the components on the electrophoresis gel. In order to determine size in base pairs of fragments of interest, a graph of the e relationship between the size and migration of the bands in the 1 KGB plus DNA Ladder was assembled (Figure 4), and a line of best fit was determined.The relationship between the base 1 O log of size and migration is linear, and graphing them together gave a trend line with an ex. action useful in determining the size of experimental fragments with known migration values. These were the fragments obtai ned by cleaving the plasmids with the Handbill restriction enzyme. Table 2 page 9 organizes the sizes and migration distances for the fragments of the standard included during electrophoresis. These values were used to construct the calibration curve m mentioned before (Figure 4).Figure 3 shows the agrees gel obtained by gel electrophoresis. Ta able 3 lists all sizes determined based on comparison with the calibration curve generated from migration standards (Figure 4). Sizes are noted for both the vector and the insert (4). Analysis of Reporter Gene Expression Investigation of gene regulation and interaction of environmental rabbinate a ND/or glucose with genotype required GAP+ cells to be spread on various plates, an d fluorescence to be observed over time.Table 4 summarizes the observations of the phenotype o f patches streaked onto AMP plates containing or lacking rabbinate and/ or glucose. Glowing patches suggest expression of the GAP gene. Observations show that the rabbinate sample pop site for the GAP insert fluoresced brightly as time went on. The sample with rabbinate and 0. 2 % glucose increasingly fluoresced over time, while plates higher in percentage glucose c imposition did not fluoresce. Cells that were GAP were also spread in order to serve as a surrogate et marker.These cells do not contain the gene for GAP, so they will not fluoresce under IV light . This gives a comparison, making it easier to determine if cells are expressing GAP fluoresce once or not page 10 DISCUSSION Regulation of Gene Expression: The samples that were grown with rabbinate, inclining, and varying amounts of glucose showed that the presence of glucose in a bacterium's surrounding environment NT can affect the ability of its rabbinate bad promoter. The plate with no glucose added flour cede brightly, while the plates with glucose added showed very little to no fluorescence.The only plate with glucose added that fluoresced in the end was the plate with the least glucose ad ded These results are due to the glucose inhibiting the rabbinate Oberon from trap inscribing the bad promoter DNA. When glucose is present in a bacterium, the cell metal likes the glucose instead of the rabbinate, and the rabbinate Oberon is not utilized. However, when the cell is lacking glucose, it reaches a state of ââ¬Å"hungerâ⬠and begins producing cyclic adenosine Mephistopheles (CAMP). This reacts with the CAMP receptor protein (CROP), who chi allows the cell to use rabbinate to induce the transcription of the rabbinate bad prom otter.This promoter contains the genes Arab area , and award, which are part of the rabbinate Oberon. This system can only function if rabbinate is present in the cell; otherwise the gene arc will prevent the rabbinate Oberon from carrying out transcription by forming a ââ¬Å"knot,â⬠or loop in the DNA The rabbinate bad promoter reacts with the GAP gene to show when the Arabian SSE Oberon is in use and how strongly it is induced by rabbi nate (5). The plate with the least glucose added began to glow over time, as the cell be an using up the glucose in its environment by metabolize it for energy.It started to FL recurrences dully once the concentration of glucose was not high enough to fully repress the AR baboons Oberon, showing that there is a range of repression and induction, not just a state of â⬠onâ⬠and ââ¬Å"off' for page 11 these function. The more the bacteria used the glucose, the less of it was arrow ND to repress the Oberon, which is why its fluorescence strength grew over time. If the study WA s to be continued past the 96 hour mark, all of the plates would have eventually fluoresced as t hey used up their loses resources and began activating the rabbinate Oberon (4).

An Outline of the Cell Theory
Chapter 2 IB Biology 2. 1 Cell Theory 2. 1. 1 Outline the cell theory (2). â⬠¢All organisms are composed of one or more cells â⬠¢Cells are the smallest units of life â⬠¢All cells come from preexisting cells â⬠¢TOK: cell theory replaces the former ideas of spontaneous generation or abiogenesis in which inanimate matter assembles itself into living forms â⬠¢Exception: muscle cells- more than 1 nucleus, very long; (fungal cells) hyphae roots- not a single unit; protoctista- not specialized to single function; subcellular things like organelles 2. 1. Discuss the evidence for the cell theory (3). â⬠¢Robert Hooke first described cells in 1665 while observing cork with a microscope he built. Coined the term ââ¬Å"cellâ⬠Antoine van Leeuwenhoek observed the 1st living cells and referred to them as animalcules. ââ¬Å"microscopeâ⬠â⬠¢In 1838, botanist Mathias Schleiden stated that plants are made of independent separate being called cells. Later, Theoder Schwann made a similar statement about animals. â⬠¢The 2nd principle continues to gain support because we have not been able to find any living entity that is not made of at least one cell. Louis Pasteur in the 1860s performed experiments to support the last principle. After sterilizing chicken broth by boiling, Pasteur showed that living organisms would not ââ¬Ëspontaneouslyââ¬â¢ reappear. ââ¬Å"biogenesisâ⬠â⬠¢Only after exposure to preexisting cells was life able to re-establish itself in the chicken broth. â⬠¢Eukaryotes- mitosis; prokaryotes- binary fission; thus all cells have a common ancestor- original ancestral form 2. 1. 3State that unicellular organisms carry out all the functions of life (1). â⬠¢Functions include: Metabolism- chemical reactions that occur within an organism â⬠¢Growth- may be limited but is always evident in some way â⬠¢Reproduction- hereditary molecules that can be passed to offspring â⬠¢Response- to environment is imperative to survival â⬠¢Homeostasis- maintain a constant internal environment ex: temp â⬠¢Nutrition- provide a source of compounds with many chemical bonds which can be broken to provide the organism with the NRG and the nutrients necessary to maintain life CHNOPS 2. 1. 4 Compare the relative sizes of molecules, cell membrane thickness, viruses, bacteria, organelles and cells, using the appropriate SI unit (3). Cells- 100 micrometers (plant) â⬠¢Organelles- < 10 micrometers â⬠¢Bacteria- 1 micrometer â⬠¢Viruses- 100 nanometersâ⬠¢Membranes- 10 nanometers thick â⬠¢Molecules- 1 nanometer â⬠¢Animal cell- 10 micrometers â⬠¢cm = 10-2 m â⬠¢mm = 10-3 m â⬠¢um = 10-6 m â⬠¢nm = 10-9 m â⬠¢A = 10-10 m 2. 1. 5 Calculate the linear magnification of drawings and the actual size of specimens in images of known magnification (2). â⬠¢Magnification = size of image divided by the size of specimen â⬠¢Magnification = measured length / scale ba r level â⬠¢Actual size = measured length / magnification 2. 1. Explain the importance of the surface area to volume ratio as a factor limiting cell size (3). â⬠¢In the cell, the rate of heat and waste production and rate of resource consumption are functions that depend of its volume. â⬠¢Most of the chemical reactions occur in the interior of the cell and its size affects the rate of these reactions.â⬠¢The surface of the cell, the membrane, controls what materials move in and out of the cell. â⬠¢Cells with more surface are per unit volume are able to move materials in and out of the cell, for each unit volume of the cell. As the width of the object increases, the surface area also increases but at a much slower rate than the volume. â⬠¢This means that a large cell has less surface area to bring in needed materials and to rid the cell of waste than a small cell. â⬠¢Because of this, cells are limited to the size they can attain and still be able to carry ou t the functions of life. Large animals have more cells not larger ones. â⬠¢A large surface area to volume ratio means the cell can act more efficiently: for every unit of volume that requires nutrients or produces waste, there is more membrane to serve it. But this is not always an advantage- cell can lose heat quickly.â⬠¢As organisms grow, cells divide. 2 small cells are more efficient than one. â⬠¢Alveoli in lungs maximize surface for gas exchange. 2. 1. 7 State that multicellular organisms show emergent properties (1). â⬠¢Different things come together to make process â⬠¢Cells-tissues-organs-etc. â⬠¢Ability to reproduce themselves. Allows possibility of growth and for replacement of damaged or dead cells. 2. 1. 8 Explain that cells in multicellular organisms differentiate to carry out specialized functions by expressing some of their genes but not others (3). Start out as single cell that reproduces at a rapid rate then the resulting cells go through a dif ferentiation (different cells- different functions- to run an organism) process to produce all required cell types that are necessary for organism. â⬠¢Every cell in a multicellular organism contains all the genes of that organism. However, the genes that are activated vary from cell to cell. â⬠¢Differentiation- when we break something complex into its component pieces, they each appear to be simple. Combined, they can perform a whole new function.Cells within a multi cellular organism specialize their function. â⬠¢Examples: muscles cells, cardiac cells â⬠¢This differentiation process is the result of the expression of certain specific genes but not others â⬠¢Genes allow for the production of all different cells in the organism â⬠¢Each cell contains all the genetic info for the production of the complete organism â⬠¢Each cell becomes a specific type of cell dependent of which DNA segment becomes active 2. 1. 9 State that stem cells retain the capacity to d ivide and have the ability to differentiate along different pathways (1). Retain ability to divide and differentiate into various cell types â⬠¢Embryonic stem cells retain the ability to form any type of cell in an organism and can even form a complete organism â⬠¢When stem cells divide to form a specific type of tissue, they also produce some cells that remain as stem cells. This allows for the continual production of a particular type of tissue.â⬠¢Pluripotent- give rise to any type of cell â⬠¢Treating diseases? 2. 1. 10 Outline one therapeutic use of stem cells (2). â⬠¢Replace differentiated cells lost due to injury Therapeutic cloning- implanted stem cells replace lost cells â⬠¢Tissue- specific stem cells- these cells reside in certain tissue types and can only produce new cells of that particular tissue â⬠¢For example, stem cells have been introduced to humans to replace the damaged bone marrow of some leukemia patients â⬠¢Bone marrow transplants are one of the many therapeutic uses of stem cells. Stem cells found in the bone marrow give rise to the red blood cells, white blood cells and platelets in the body. These stem cells can be used in bone marrow transplants to treat people who have certain types of cancer.When a patient has cancer and is given high doses of chemotherapy, the chemotherapy kills the cancer cells but also the normal cells in the bone marrow. This means that the patient cannot produce blood cells. So before the patient is treated with chemotherapy, he or she can undergo a bone marrow harvest in which stem cells are removed from the bone marrow by using a needle which is inserted into the pelvis (hip bone). Alternatively, if stem cells cannot be used from the patient then they can be harvested from a matching donor.After the chemotherapy treatment the patient will have a bone marrow transplant in which the stem cells are transplanted back into the patient through a drip, usually via a vein in the chest or the arm. These transplanted stem cells will then find their way back to the bone marrow and start to produce healthy blood cells in the patient. Therefore the therapeutic use of stem cells in bone marrow transplants is very important as it allows some patients with cancer to undergo high chemotherapy treatment.Without this therapeutic use of stem cells, patients would only be able to take low doses of chemotherapy which could lower their chances of curing the disease. â⬠¢Ethical issues- embryonic stem cells come from embryos obtained from labs doing IVF. involves death of embryo. 2. 2 Prokaryotic Cells 2. 2. 1 Draw and label a diagram of the ultrastructure of Escherichia coli (E. coli) as an example of a prokaryote (1). â⬠¢Plasmid is circular thing not on diagram.

It gives the cell its shape, prevents excessive water up take by osmosis and is the reason why the whole plant can hold itself up against gravity. Prevents entry of pathogens. Allows turgor pressure/ high pressure to develop inside the cell. The animal cell contains glycoproteins in their extracellular matrix (ECM) which are involved in the support, movement and adhesion of the cell. Cell to cell interaction, strengthens plasma membrane, allows attachment between adjacent cells, directs stem cells to differentiate 2. 4. 1 Draw and label a diagram to show the structure of membranes (1). 2. 4. 2 Explain how the hydrophilic and hydrophobic properties of phospholipids help to maintain the structure of cell membranes (3). One area of membrane is water soluble and polar and is hydrophilic â⬠¢The other area isnââ¬â¢t water soluble and is non polar- hydrophobicâ⬠¢These hydrophobic and hydrophilic regions cause phospholipids to always align as a bilayer if there is water present and there is a large number of phospholipid molecules â⬠¢Membrane is flexible since fatty acid tail do not strongly attract one another â⬠¢What maintains the overall structure of membrane is the tendency water has to form hydroge n bonds â⬠¢In hydrophobic region (fatty acid tails) in animal cells these are cholesterol molecules- determine membrane fluidity (changes temp) â⬠¢Proteins are embedded in fluid matrix of phospholipid bilayer (mosaic effect) â⬠¢Integral proteins have both hydrophobic and hydrophilic regions in the same protein â⬠¢Hydrophobic region (mid section of phospholipid membrane) holds protein in place â⬠¢Hydrophilic region is exposed to water solutions on either side of membrane â⬠¢Peripheral proteins do not protrude into the middle hydrophobic region but remain bound to the surface of the membrane 2.4. 3 List the functions of membrane proteins (1). â⬠¢Hormone binding sites- have specific shapes that fit shape of specific hormone â⬠¢Enzymatic action- catalyze chemical reactions â⬠¢Cell adhesion- proteins hook together to form connections â⬠¢Cell to cell communication- provide identification â⬠¢Channels for passive transport- high to low concentrati on â⬠¢Pumps for active transport- proteins shuttle a substance from one side of membrane to another by changing shape; ATP 2. 4. 4 Define osmosis and diffusion (1). â⬠¢Diffusion is the passive movement of particles from a region of high concentration to a region of low concentration.Osmosis is the passive movement of water molecules, across a partially permeable membrane, from a region of lower solute concentration to a region of higher solute concentration (hypo-osmotic solution to hyperosmotic solution). â⬠¢Facilitated diffusion- involves a membrane with specific carrier proteins that are capable of combining with the substance to and its movement 2. 4. 5 Explain passive transport across membranes by simple diffusion and facilitated diffusion (3). â⬠¢Simple diffusion- substances other than water move between phospholipids molecules or through proteins which possess channels â⬠¢Facilitated diffusion- nonchannel protein carriers change shape to allow movement of substances other than water. No NRG.Polar molecules need help. â⬠¢Substances that move passively across membrane are influenced by size and shape â⬠¢Small substances and nonpolar move with ease; large, polar, or both do not â⬠¢Channel proteins- create a hydrophilic pore in membrane through which small changed particles (ions) can diffuse into cell â⬠¢Transport proteins- help move substances (glucose) into cell. Substrate binds to protein which carries molecules across membrane and releases it inside cell 2. 4. 6 Explain the role of protein pumps and ATP in active transport across membranes (3). â⬠¢Active transport involves the movement of substances through the membrane using NRG from ATP.The advantage of active transport is that substances can be moved against the gradient, meaning from low to high concentration â⬠¢This is possible because the cell membrane has protein pumps embedded it which are used in active transport to move substances using ATP â⬠¢E ach protein pump only transports certain substances so the cell can control what comes in and goes out â⬠¢Transport or carrier proteins â⬠¢Ex: Na +/ K + pump. Sodium moved out of cell, potassium moved in (important for nerve cells) 2. 4. 7 Explain how vesicles are used to transport materials within a cell between the rough ER, Golgi apparatus, and plasma membrane (3). â⬠¢Materials are transmitted between rough ER, Golgi app, and plasma membrane â⬠¢Nucleus contains chromosomes that contain genes for coding proteins.RNA passes from nucleus to cytoplasm â⬠¢Rough ER contains ribosomes which make proteins intended for export â⬠¢Protein goes into lumen of Golgi app for processing before it leaves through the cell surface membrane by exocytosis 2. 4. 8 Describe how the fluidity of the membrane allows it to change shape, break and reform during endocytosis and exocytosis (2). â⬠¢The phospholipids in the cell membrane are not solid but are in a fluid state allowin g the membrane to change its shape and also vesicles to fuse with it. â⬠¢This means substances can enter the cell via endocytosis and exit the cell via exocytosis. The membrane then returns to its original state. â⬠¢In exocytosis the vesicles fuse with the membrane expelling their content outside the cell.The membrane then goes back to its original state. Endocytosis is a similar process which involves the pulling of the plasma membrane inward so that a vesicle is pinched off it and then this vesicle can carry its content anywhere in the cell. â⬠¢Cell takes up substance by surrounding it with membrane, ATP â⬠¢2 types: â⬠¢pinocytosis (substance is liquid) â⬠¢phagocytosis (substance is solid) â⬠¢endocytosis and exocytosis- active transport that requires ATP; common in unicellular organisms Summary of processes: ATP requiredConcentration gradient DiffusionNoDown (high to low) Facilitated diffusionNoDown OsmosisNoDown Active transport with carrier proteinsYes Against is possible EndocytosisYesAgainst is possible 2. 5 Cell Division 2. 5. Outline the stages in the cell cycle, including interphase (G1, S, G2), mitosis, and cytokinesis (2). â⬠¢The first stage of cell division is interphase which is divided into 3 phases; G1, S and G2. The cell cycle starts with G1 (Gap phase 1) during which the cell grows larger. This is followed by phase S (synthesis) during which the DNA is replicated. Finally, G2 (gap phase 2) is the second growth phase in which organelles increase in number, cell grows and preps for mitosis, DNA begins to condense form chromatin to chromosomes and microtubules begin to form. â⬠¢? The fourth stage is mitosis, which is divided into prophase, metaphase, anaphase and telophase.During mitosis the spindle fibers attach to the chromosomes and pull sister chromatids apart, providing the same genetic material to each of these locations. This stage separates the two daughter genomes. â⬠¢Finally, cytokinesis is the last stage during which the cytoplasm divides to create two daughter cells. In animal cells the cell is pinched in two to form a cleavage furrow while plant cells form a plate between the dividing cells. 2. 5. 2 State that tumors (cancer) are the result of uncontrolled cell division and that these can occur in any organ or tissue (1). â⬠¢Proto-oncogenes are genes that produce proteins, which stimulate growth (cell division). If mutation occurs, a tumor will form. Mutations: radiation, viruses, chemicals that are carcinogenic, EM radiation 2. 5.3 States that interphase is an active period in the life of a cell when many metabolic reactions occur, including protein synthesis, DNA replication, and an increase in the # of mitochondria and/or chloroplasts (1). 2. 5. 4 Describe the events that occur in the 4 phases of mitosis (2). â⬠¢During prophase, chromatin becomes chromosomes, nuclear envelope disintegrates, the spindle microtubules begin to form, centrosomes move toward opposite poles of cell due to lengthening microtubules. Each chromosome consists of 2 identical sister chromatids held together by a centromere. During metaphase, the chromatids move to the equator and the spindle microtubules from each pole attach to each centromere on opposite sides. â⬠¢During anaphase, the spindle microtubules pull the sister chromatids apart splitting the centromeres. This splits the sister chromatids into chromosomes. Each identical chromosome is pulled to opposite poles. Chromatids of each duplicated chromosome separate and become unduplicated chromosomeâ⬠¢During telophase, the spindle microtubules break down and the chromosomes uncoil and so are no longer individually visible. Also the nuclear membrane reforms. Chromosomes become chromatin (shapeless). Centrioles replicate in animal cells. The cell then divides by cytokinesis to form two daughter cells with identical genetic nuclei. 2. 5. Explain how mitosis produces 2 identical nuclei (3). â⬠¢During proph ase, the chromosomes become visible. The nuclear envelope disintegrates and the spindle microtubules grow and extend from each pole to the equator. â⬠¢At metaphase the chromatids move to the equator. The sister chromatids are two DNA molecules formed by DNA replication and are therefore identical.â⬠¢These sister chromatids are then separated in anaphase as the spindle microtubules attaches to centromere and pulls the sister chromatids to opposite poles. As the sister chromatids separate they are called chromosomes. This means that each pole has the same chromosomes (same genetic material). Finally the microtubules break down, the chromosomes uncoil and the nuclear membrane reforms. The cell then divides into two daughter cells with genetically identical nuclei. â⬠¢4 chromosomes in parent cell = 4 chromosomes in each daughter cell â⬠¢duplicated chromosome with 2 strands connected by centromere and chromosome is 1 strand 2. 5. 6 State that growth, embryonic development , tissue repair, and asexual reproduction involve mitosis (1). â⬠¢Growth- production of similar cells â⬠¢Embryonic development- allows zygote to grow into multicellular organism â⬠¢Tissue repair- wounds need identical replacement cells â⬠¢Asexual reproduction- allows for a rapid and significant increase in number of individuals

Impact of Recent Changes in Capitalism on Social and Economic Status of Women The WritePass Journal
Impact of Recent Changes in Capitalism on Social and Economic Status of Women Introduction Impact of Recent Changes in Capitalism on Social and Economic Status of Women ). The list is certainly endless. In addition, the education system has become more open to the girl child including in fundamentalist countries such as Iran which have seen a growing number of women graduates (Castell 1996). The affirmation and recognition of womens values, the growing women movements and critique of patriarchalism are some of the most important transformations that have contributed to the new status of women. Feminism As women movements continue to fight for their autonomy and recognition of womens values, the more has feminism diversified. A new frontier has emerged based on the notion of degendering of the society which implies a society free from gender associations or rather one that moves beyond gender (Murphy 2011). This new frontier in feminism has superseded the old battles that existed between equality feminism and difference feminism. By mobilizing women to oppose patriarchalism and to defend their rights, feminism has transformed to the point of canceling the distinction between men and women (Sulivan 2007). Men and women are now largely viewed as individuals with meaningful existence, liberating them from the patriarchic burden of responsibilities. This has certainly been very helpful in achieving a more equal society. Womenââ¬â¢s role in the development of the economy is increasingly being recognized. Available evidence indicates women to be powerful drivers of economic growth. A study by the Center for Economic and Policy Research found the high rate of women employment to be the driving force of the US economy. The study found that, if women had not entered the workforce over the last 30 years, the economy would have been 11% less. Today, we see several institutions including the World Bank and the Department for International Development (DFID) campaigning for more involvement of women in economic development (Aguirre et al. 2012). According to the World Bank, encouraging the growth of women entrepreneurs is as sure way of fighting poverty. Women are poised to drive the global economy in the next coming decades. Estimates indicate that nearly 1 billion of women across the world might join paid labour over the coming decade (Aguirre et al. 2012). Criticism While there seems to be a progress in womenââ¬â¢s socio-economic status driven by post-fordist relations and the neoliberal policies pursued by the several states, some countries continue to follow partriarchalism. Despite its inevitable demise, some countries tend to still follow partriarchal lines which subordinate women under mens dominance. A good example can be seen with Saudi Arabia. A womans place in Saudi Arabia is still in the home. Saudi women continue to walk in the shadow of their men. For example, despite their obvious presence, they are not allowed to participate in the public sphere (Hamdan 2005). They are viewed as non-existing in the public sphere and are silenced in public life. They continue to be subordinated to male individuals in both private and public sectors despite their qualifications. While a progress seems to have been made with respect to their education, at the core of womens education is sex segregation. Education in Saudi continues to support the prevailing gender structures, implying lower social status of Saudi women (Hamdan 2005). Perhaps more shocking news is the fact that Saudi Women are not allowed to drive. While religious reasons are generally given for denying women the right to drive, it is clear that their place is still in the home. Also, even though many women have progressed economically due to their inclusion in workforce, only a few of them work in the management positions. In spite of the increasing number of women in workplace, many of them are concentrated in the lower-status occupations. For example, while the health sector comprise of 75% of the women workforce, they are concentrated n the lower status working either as nurses and midwifery personnel or as caring cadres (WHO 2008). They are largely underrepresented at the managerial level and specialist categories such as dentists, pharmacists, and physicians. Feminist critique of sexism seems to have given justification to new forms of exploitation and oppression. With more women joining the paid workforce, the family wage model central to state-organized capitalism which viewed men as the breadwinners and women as home makers has now been replaced by the newer, more modern norm of two-earner family (Fraser 2013). While this may sound like good news, the reality is that post-fordism and neoliberal ideas have resulted in depressed wage levels, increased job insecurity, exacerbation of double shifts and the increase in the number of working hours (Fraser 2013). What was once the family wage in capitalism has now been replaced by a low-waged work. Majority of their work has not really brought liberation rather a tedious reality far from the perceived image of a working woman (Frank 1999). They remain relegated to lower positions at work. Even with many women being employed either in full or part-time positions, they are not getting to the top. Also, where their role is clearly evident, women continue to suffer from some level of hostility and public disapproval. For example, when it comes to journalism, women have proved flexible and able to forge new approaches. Their adaptability to new approaches is clearly evident with their news coverage of the September 11 events, the overthrow of Taliban forces and the bombing of Afghanistan (Chambers 2004). Women journalists developed different angles in their approach to war journalism, thereby attracting more news audiences. Yet despite the critical role that they played, a heated public debate emerged about the risks of reporting in war zones. It is clear that despite their liberation from oppression, women are still defined in terms of men. As wives and mothers, women clearly continue to suffer from some level of hostility and public disapproval that men with families do not ( Chambers 2004 p.13) In addition, some recent events have pointed to the renewed crisis of capitalism. There is currently a crisis of profitability which is facing capitalism. The profit rates are falling and many firms have been laying off workers. British capitalism is particularly in a crisis given its relatively weak position compared to other imperialist nations (FRFI 2013). The current focus on the growth of the private sector implies that priority has been placed on industrial development over social objectives. Workers wages have been cut to a massive extent and unemployment seems to be growing. Given this crisis, capitalism is now insisting on women returning to their traditional roles as domestic workers (FRFI 2013). Neoliberal ideas contributing to sexism While the recent changes experienced by capitalism seem to have contributed to the recognition of women as gender equals, recent developments continue to enact sexism. For example, many advertisements of today show nude pictures of women. What this means is that the male gaze is invited and encouraged as women continue to become objects of the gaze. Moreover, many clubs continue to feature young women stripping, lap-dancing and flashing out their breasts in public (McRobbie 2009). A hyper-culture of commercial sexuality seem to be growing, an aspect that is clearly a repudiation of feminism. Even the young women journalists who through their education are gender aware refuse to condemn such acts of commercial sexuality. It seems like the new female Subject is called upon by the society to withhold critique and to remain silent despite her freedom. Consumer and popular culture seem to be introducing invidious forms of gender re-stabilization by pretending to support female success yet tying the female subject to new post-feminist neurotic dependencies (McRobbie 2009). In order to be considered a modern sophisticated girl, the female subjects choose to withhold their critique despite their obvious image as sexual objects of menââ¬â¢s gaze. With the progress seen with womens socio-economic status, one might think that the feminists are happy to see the things they fought so hard to have come true. However, what has emerged is different from what was desired (Cornwall et al 2008). Neoliberal values seem to have created space under which women can be further oppressed and their core values undermined. The culture of neoliberalism has led to the idea of self-sufficiency and free choice. All that one has to do is to compete in the market place. Some women have even gone to great lengths to make themselves acceptable to the world of work by performing cosmetic surgery under the illusion of having freedom choice to make their own decisions (Gupta 2012). Yet some of their work goes against their core values. Many women have ventured into the sex industry under the illusion of having control over their lives. They have chosen this kind of work in the spirit of freedom of expression of their sexuality and believe that the work is liberation from the drudgery of cleaning jobs (Gupta 2012). However, the so called freedom of expression is actually reducing them to the status of ââ¬Ëcommodityââ¬â¢ and as objects of ââ¬Ëmen gazeââ¬â¢. Feminism which once fought for the liberation of women from oppression has become entangled in a dangerous liaison with neoliberal efforts to build a free market society (Fraser 2013). It has led to the notion of ââ¬Ëfreedom of choiceââ¬â¢ which ultimately has given rise to prostitution. Feministsââ¬â¢ perspective on prostitution, however, is an interesting one. Feminists argue that prostitutes are social workers and have in fact used their social concepts to contend for decriminalization of prostitution (Sullivan 2007). Feminists have formed strong links with prostitutes resulting in advances in the area of prostitution law reform. The feminist position of the sex industry is one that empowers women as long as they choose to participate. But what is progressive about womenââ¬â¢s participation in prostitution? Can women really progress by becoming sexual objects and objects of male gaze? What is revolutionary about legalizing prostitution? In fact, legalizing prostitution just makes women to become sexual commodities. The fight against sexism that has long been fought for by feminists seems to have ended up again to encouraging it. The progress in women that we have seen so far will not continue if women continue to follow neoliberal ideology that values individual choice and freedom over emancipation. Selling their bodies will not provide them with independence and empowerment that they seek but rather it will just reinforce male power and privilege. Trafficking of women and children Further, neoliberal ideology has led to the growing trafficking of women and children. This is particularly evident in Asia and the pacific region where human trafficking has grown to become a booming business. Millions of children in the pacific region are traded to work in brothels or sweatshops. Human trafficking has not grown by accident but as a result of free trade and structural adjustments brought about by neo-liberalism. Sex trafficking is currently a growing market in some parts of Eastern Europe, most notably Romania and Albania (FRFI 2013) Conclusion There is no doubt that the socio-economic status of women has improved following the recent changes in capitalism. This is evident in their inclusion in the paid workforce, their enrollment in eductation and increased participation in the public sphere including in politics. However, to some extent, these changes have painted a gloomy picture with regard to the status of women. A vast majority of them continue to occupy positions at the low levels of the organization. Also they continue to suffer from some level of hostility and public disapproval. Neoliberal ideology has led to their increasing commodification and increased trafficking of women and children. A hyper-culture of commercial sexuality seem to be growing, an aspect that is clearly a repudiation of feminism. Nonetheless, a huge progress has been made. Today, there are many successful women in the capitalist society. In fact, many women seem to have embraced the capitalism and showed support of it due to their improved social and economic status. If their status is to be further improved in post-fordist employment, policy initiatives must address the issues of womens employment, skills and training (Burrows Loader 2003). Furthermore, there is need for public policy to challenge the polarized labour market that has emerged from post-fordism. Neo-liberal policies which support the development of a polarized market are socially divisive. Also, feminist scholars need to caution Women against prostitution. Selling their bodies will not provide them with independence and empowerment that they seek but rather it will just reinforce male power and privilege Reference Acker, J., 2004. ââ¬ËGender, capitalism and globalizationââ¬â¢.

Effective Manager in the Global Context
Effective Manager in the Global Context Introduction The world has witnessed radical changes in information and communication technology. As of now, through teleconferencing, individuals from different countries are able to hold a conference from the comfort of their homes or offices without having to travel. Changes in the transport industry has also made is possible for individuals access every part of the globe very fast.Advertising We will write a custom report sample on Effective Manager in the Global Context specifically for you for only $16.05 $11/page Learn More Fast jets have made it possible that one can manage to visit all continents of the world within one day. All this changes translate into a different approach to management. Unlike in the traditional setting where geographical constraints limited management scope, the modern manager requires skills to be able to respond to global concerns. In this report, I intend to examine competencies and skills of an effective manager in the glo bal context. Through the analysis in this report, I will evaluate my management skills, in order to determine whether I am an effective manager or not. Moreover, based on the analysis of my management skills, I formulate an action plan that I am to implement towards becoming a more competent and effective manager in the global context Time Management Most of the managers, who have excelled in their duties, are efficient time managers (Dalziel Schoonover, 1988). Organizations operating across the globe can only succeed if managers pay close attention to time management. This requires taking into account time zone differences and being able to plan so that there are no inconveniences in operation. Efficient time management means that one is able to allocate time properly both in their professional life and in their personal life. I used to be a victim of poor time management. I was generally a last minute person, which could make my work strenuous and poorly executed. However, over t ime and through lessons from this module, I have been able to realize the power of excellent time allocation. Currently, am able to work stress free due to planning. Consequently, I am able to execute tasks well in my work place. Time management is an important component in personal organization. Personal organization dictates the manner one assigns oneself to tasks (Dalziel Schoonover, 1988). Proper personal organization is not possible without scheduling or time budgeting. However, personal organization goes beyond time management; it encompasses even dressing and how one plans own work desk or home.Advertising Looking for report on business economics? Let's see if we can help you! Get your first paper with 15% OFF Learn More Proper personal organization skills help one to accomplish tasks in a systematic manner, and in a timely way. I have always taken personal organization seriously because through it I am able to deal with activities and schedules prop erly. From experience, I know that time management skills are important towards good emotional as well as physical health and stability at work. In all the places that I have worked, I have excelled because of excellent time management. I manage to balance my social life with work life due to proper time management. Through the management module, I am now armed with more scientific ways that I can apply towards enhancing my time management skills. I realize that proper time management helps busy employees to create enough time to address to other personal needs e.g. social and emotional needs. Even though I am excellent at time budgeting, I realized that I would plan but fail in following through with the plans. From the module, I have learned that it is important to have a diary that allows me to plan and stick to the plan made. Moreover, in case I do not meet my diary specifications, I am able to strategize on how to make up for lost time. Critically, I have learnt to differentiat e plans in terms of short-term plan, middle-term plans, and long-term plans. By so doing, I am able to avoid mixing issues and prioritizing. This aspect is very significant because it has enabled me to have a daily time management strategy that does not jeopardize my long term or midterm needs. Project Management In this module, I have managed to learn more on the management functions, which are vital to the field of project management. As Witzel (2003, pp.96-101), discusses, project management is a very dynamic undertaking. There are many project management tools that I have been able to learn from this course. For example, I have leant how to apply Gantt charts, mind maps, as well as knowledge development to ensure project success. Project management is taken seriously globally due to increased demand for managers to respond to competition and other market trends (Meredith Mantel, 2010).Advertising We will write a custom report sample on Effective Manager in the Global Co ntext specifically for you for only $16.05 $11/page Learn More Apart from the tools used in project management, the module has helped to appreciate the dynamics of managing an international project. In day-to-day operations of an organization, managers often rely on ad-hoc information to make tactical decisions on matters that require immediate response. In a global context, this means managers have to institute proper feedback mechanisms and invest in information technology. Information technology tools would help a project manager of a widespread project to remain in touch with project assistants. This is pivotal, as there are often urgent decisions that have to be made. Stress Management Another critical skill I have learnt during the model is how to go about stress management. I realize that many people labor with effects of stress and yet as Lazarus and Folkman (1984) point out, stress is something that one can control. From the module, I have learnt that stre ss comes because of many factors. The common causes of stress include problems in personal relationships, financial difficulties among others. Stress can emerge due to insecurity in oneââ¬â¢s jobs, problems in controlling staff, or other issues to do with family or work roles. Learning on how to manage stress is mandatory for every effective manager because normal day to day work experiences translate into forms of stress (Bower Segerstrom, 2004, pp.9-11). As illustrated in the module classes, planning is central to the management of stress. Therefore, to avoid stress, I ensure that I plan and handle my assignments in good time. Further, I have come to understand different ways of coping with others especially when working in groups. Sometimes, working in groups may lead to delays in the accomplishment of the required assignments. In dealing with others, I have learnt ways of detecting signs of stress and thus I am able to act upon them fast before they turn me into a stressed i ndividual. Interpersonal Skills Management in a global context often means working with people from different nations. A cultural difference across nations means that different people approach business and even social interactions very differently. Therefore, managers in a global context have the challenge of being able to transform cultural diversity into a strength rather than a weakness; cause of conflicts in the organization.Advertising Looking for report on business economics? Let's see if we can help you! Get your first paper with 15% OFF Learn More Effective management is about weaving together a dream team or being part of a dream team than helps an organization to achieve its objectives (Dixon, 2004). Interpersonal skills are poignant in ensuring a good working relationship with others. I belief I have very excellent interpersonal skills that I have demonstrated through my various encounters with people at organizational level. In my daily encounters, I find it easy to communicate freely in groups. I am also capable of establishing rapport quickly with people, which always puts me at an advantaged position in as far as working with others is concerned. However, this module has endowed me with deeper insights into the realm of interpersonal skills, by making me realize that I can as well use my interpersonal skills to enable other group members who are introverts to express themselves and share their own opinions before any group. Furthermore, I have learned about the various barriers to effective interpersonal relationships, and ways to overcome those barriers. Another aspect that normally puts individuals at loggerhead with others is not knowing how to ask questions in groups (Dixon, 2004). This is because at times some questions can send out negative signals, hence barring effective interpersonal relationships. I have realized that what I need to improve on is my listening skills so that I can be able to learn from other people. Conclusion Managing in a global context requires one to have dynamic skills due to the challenges resulting from global diversity. It is imperative for a manager in the global context to have sharp interpersonal, project management, time management and stress management skills. As presented in this report, it is clear that I have learnt a lot from the management module. From the module, I have come to appreciate the complexity of a global managing context. However, I am encouraged because I have also learnt a number of techniques that will help me become a competent and effec tive manager in the global context. In line with the course content, I have been able to reflect on my strengths and weaknesses. Based on such an analysis, I have come up with an action plan, which will enable me to improve and increase my competence. Action Plan I appreciate that I can be an effective manager but there are areas in which improvements are necessary. The following action plan looks at what steps I am going to take to ensure the journey of growth continues. To better appraise my strengths and weakness, below is a SWOT model of the same. Strengths I plan my time I have learnt different project management tools I have capacity to identify stressors I am an extrovert and always engages others Opportunities I have learnt how to use diary and other tools in time management I have learnt about many project management tools e.g. Gantt charts I have learnt about stressors and organizational stress management programs Opportunity to learn more about others Weakness I do not follow through on plans Lack experiences in using project management tools Lack experience developing stress management programs for big organizations I tend not to listen to other in interpersonal interactions Threats Cultural animosity in the world Ever changing project management tools minimizing my competence Numerous stressors in global context People who do not appreciate value of interpersonal relations; hardliners in the global arena Growth Objectives Based on the SWOT model presented above, the following are my growth objectives To work on time management skills To improve my listening skills thus improve my interpersonal skills To practice with project management skills so as to become competent in their use To learn more about how stress management programs are organized in multinational corporation Short Term Actions Interpersonal skills are elementary for any effecting manager. I believe that I am an extrovert and thus I tend to dominate others whene ver in groups. To start with, when it comes to performance management there is the temptation to manage peopleââ¬â¢s performance from a personal perspective. This means that they regard their own competencies and skills as perfect. However, owing to the class module, I have learnt that it is critical to open up to othersââ¬â¢ ways of doing things as long as they stick to the organizational objectives. Consequently, I will work tirelessly towards being someone who appreciates other peopleââ¬â¢s point of view. I will begin this through, on a daily basis, trying to empathize and understand others in the context of their competencies. Rather than manage performance by harassing others based on their capability, I have to learn how to motivate them and encourage optimism so they may bring their best to the fore. This I kind of disposition I plan to build by practicing the same consciously until I internalize the same. Reflecting on my capability to manage stress, I also have eno ugh that I ought to look into. I am happy that I have learnt a lot about how to identify stressors and manage stress at a personal level. However, I need to learn more in terms of how to design and institute stress management mechanisms in organizations that are operating internationally. All managers have to learn not only how to effectively deal with stress at a personal level but also in an organization. On a daily basis, I plan to come up with a personal program of managing stress. If the program works for me, then I could easily transform the same into an organization wide stress management program. However, I am well aware that people are different. Away from stress management, my action plan is not complete without considering how I am going to improve my project management skills. In the module, I learnt more about how to handle projects. However, effective use of given tools comes with experience. I have to start practicing how to employ tools like balanced scorecard and ot her qualitative tools necessary in management. Using readily available scenarios, I plan to continue applying the tools with the aim of internalizing the same. While the other activities require daily efforts, on the use of the tools, I plan to exercise using them at least once every week. Long Term Action I need to grow interpersonal skills especially in appreciating how cultural diversity may become a barrier to effective management. In the globalizing management setting, managers have to interact with people of different nationality and cultural backgrounds. Therefore, I have to continually learn about other people and their way of life. By so doing, I will be able to know how to approach and interact comfortably with them. I plan to start reading more about how people from other cultures do business and how they respond or interact. When it comes to time management, my long-term plan is augment long-term planning in my time management schemes. Through strategic planning, I am ab le to take a panoramic approach to operations thus guaranteeing that nothing of value is excluded from my priorities. In relation to stress management, my long-term plan, as an effective manager, I will keep learning more about stressors and what kind of programs can help in eradicating the given stressors. I plan to take time to identify case studies on stress management towards better understanding of how the same is handled in other companies. Finally, in relation to project management skills, my long-term plan is to enroll into institutions o learning at a later stage to augment my knowledge and skills in the use of different skills.

Billy Bishop - World War I Ace
Billy Bishop - World War I Ace Billy Bishop - Early Life Career: Born February 8, 1894 at Owen Sound, Ontario, William Billy Bishop was the second (of three) child of William A. and Margaret Bishop.à Attending Owen Sound Collegiate and Vocational Institute as a youth, Bishop proved a marginal student though excelled in individual sports such as riding, shooting, and swimming.à Possessing an interest in aviation, he unsuccessfully attempted to build his first aircraft at age fifteen.à Following in his older brothers footsteps, Bishop entered the Royal Military College of Canada in 1911.à Continuing to struggle with his studies, he failed his first year when he was caught cheating. Pressing on at RMC, Bishop elected to leave school in late 1914 following the beginning of World War I.à Joining the Mississauga Horse regiment, he received a commission as an officer but soon fell ill with pneumonia.à As a result, Bishop missed the units departure for Europe.à Transferred to the 7th Canadian Mounted Rifles, he proved an excellent marksman.à Embarking for Britain on June 6, 1915, Bishop and his comrades arrived at Plymouth seventeen days later.à Sent to the Western Front, he soon became unhappy in the mud and tedium of the trenches.à After seeing a Royal Flying Corps aircraft pass over, Bishop began seeking an opportunity to attend flight school.à Though he was able to secure a transfer to the RFC, no flight training positions were open and he instead learned to be an aerial observer. Billy Bishop - Beginning with the RFC: Assigned to No. 21 (Training) Squadron at Netheravon, Bishop first flew aboard an Avro 504.à Learning to take aerial photos, he soon proved skilled at this form of photography and began teaching other aspiring airmen.à Sent to the front in January 1916, Bishop operated from a field near St. Omer and flew Royal Aircraft Factory R.E.7s.à Four months later, he injured his knee when his aircrafts engine failed at takeoff.à Placed on leave, Bishop traveled to London where his knees condition worsened.à Hospitalized, he met socialite Lady St. Helier while recuperating.à Learning that his father had suffered a stroke, Bishop, with St. Heliers aid, obtained leave to briefly travel to Canada.à Due to this trip, he missed the Battle of the Somme which started that July.à Returning to Britain that September, Bishop, again with St. Heliers assistance, finally secured admission to flight training.à Arriving at the Central Flying School at Upavon, he spent the next two months receiving aviation instruction.à Ordered to No. 37 Squadron in Essex, Bishops initial assignment called for him to patrol over London to intercept night raids by German airships.à Quickly boring of this duty, he requested a transfer and was ordered to Major Alan Scotts No. 60 Squadron near Arras.à Flying older Nieuport 17s, Bishop struggled and received orders to return to Upavon for further training.à Retained by Scott until a replacement could arrive, he achieved his first kill, an Albatros D.III, on March 25, 1917, though he crashed in no mans land when his engine failed.à Escaping back to Allied lines, Bishops orders for Upavon were rescinded. à Billy Bishop - Flying Ace: Quickly earning Scotts trust, Bishop was appointed a flight commander on March 30 and achieved his second victory the following day.à Permitted to conduct solo patrols, he continued to score and on April 8 downed his fifth German aircraft to become an ace.à These early victories were obtained via a hard-charging style of flying and fighting.à Realizing that this was a dangerous approach, Bishop shifted to more surprise-oriented tactics in April.à This proved effective as he downed twelve enemy aircraft that month.à The month also saw him earn a promotion to captain and win the Military Cross for his performance during the Battle of Arras.à After surviving an encounter with German ace Manfred von Richthofen (The Red Baron) on April 30, Bishop continued his stellar performance in May adding to his tally and winning the Distinguished Service Order. On June 2, Bishop conducted a solo patrol against a German airfield.à During the mission, he claimed three enemy aircraft shot down as well as several destroyed on the ground.à Though he may have embellished the results of this mission, it won him the Victoria Cross.à A month later, the squadron transitioned into the more powerful Royal Aircraft Factory SE.5.à Continuing his success, Bishop soon ran his total to over forty achieving the status of highest-scoring ace in the RFC.à Among the most famous of the Allied aces, he was withdrawn from the front that fall.à Returning to Canada, Bishop married Margaret Burden on October 17 and made appearances to bolster morale.à Following this, he received orders to join the British War Mission in Washington, DC to assist in advising the US Army on building an air force. Billy Bishop - Top British Scorer: In April 1918, Bishop received a promotion to major and returned to Britain.à Eager to resume operations at the front, he had been passed as British top scorer by Captain James McCudden.à Given command of the newly-formed No. 85 Squadron, Bishop took his unit toà Petite-Synthe, France on May 22.à Familiarizing himself with the area, he downed a German plan five days later.à This began a run that saw him raise his tally to 59 by June 1 and reclaim the scoring lead from McCudden.à Though he continued to score over the next two weeks, the Canadian government and his superiors became increasingly concerned about the blow to morale if he were to be killed.à As a result, Bishop received orders on June 18 to depart the front the following day and travel to England to aid in organizing the new Canadian Flying Corps.à Angered by these orders, Bishop conducted a final mission on the morning of June 19 which saw him down five more German aircraft and raise his score to 72.à Bishops total made him the top-scoring British pilot of the war and second-highest Allied pilot behind Rene Fonck.à As many of Bishops kills were unwitnessed, historians in recent years have begun to question his total.à Promoted to lieutenant colonel on August 5, he received the post of Officer Commanding-designate of the Canadian Air Force Section of the General Staff, Headquarters Overseas Military Forces of Canada.à Bishop remained in the job until the end of the war that November. Billy Bishop - Later Career: Discharged from the Canadian Expeditionary Force on December 31, Bishop began lecturing on aerial warfare.à This was followed by a short-lived passenger air service that he started with fellow Canadian ace Lieutenant Colonel William George Barker.à Moving to Britain in 1921, Bishop remained engaged in aviation concerns and eight years later became chairman of British Air Lines.à Financially devastated by the stock market crash in 1929, Bishop returned to Canada and ultimately obtained a position as vice president of the McColl-Frontenac Oil Company.à Resuming military service in 1936, he received a commission as the Royal Canadian Air Forces first air vice-marshal.à With the beginning of World War II in 1939, Bishop was elevated to air marshal and tasked with overseeing recruitment. Highly effective in this role, Bishop soon found himself compelled to turn away applicants.à Also overseeing pilot training, he aided in authoring the British Commonwealth Air Training Plan which guided the instruction of nearly half those who served in the Commonwealths air forces.à Under extreme stress, Bishops health began to fail and in 1944 he retired from active service.à Returning to the private sector, he accurately predicted the postwar boom in the commercial aviation industry.à With the beginning of the Korean War in 1950, Bishop offered to return to his recruitment role but his poor health led to the RCAF politely declining.à He later died on September 11, 1956, while wintering in Palm Beach, FL.à Returned to Canada, Bishop received full honors before his ashes were interred atà Greenwood Cemetery in Owen Sound.

Negotiation Skills Study 03069 Essay Example | Topics and Well Written Essays - 2500 words
Negotiation Skills Study 03069 - Essay Example Some of the main terms, which will be explored in the paper are negotiation as well as negotiation skills. According to Manning and Robertson (2004), negotiation skills are the abilities needed in the arbitration process. Brett (2012) asserts that negotiation is a process in which confronting parties focus on resolving their issues in an effort to attain a common goal. Therefore, this paper is only limited to detailing the fact that negotiation is for all persons and answering the question on whether or not negotiation skills are similar in all fields they are practiced. It is indisputably that negotiation is meant for all people regardless of their age, gender, as well as ethnic affiliation and the required skills are different in diverse settings or situations. According to Caputo (2012, p. 374), negotiation skills are imperative and they should be improved in order to ensure a competitive edge in the business and political arena. This is a factual statement, considering that such skills are imperative in various fields and are vital to professional as well as laymen. It is evident that negotiation cannot be said to be a process that is meant for only top salespeople, advocates, or skilled diplomats. However, it is something that all persons do in their day to day life. Although negotiation skills are not similar in all fields, everyone does negotiate and different skills are required, depending on what is being negotiated for. For instance, in peace accords as well as when organisations are formulating mergers, the negotiation stakes are higher and dramatic as compared to when people are simply negotiating to get a new job (Barron 2003, pp. 635-637). Different people undergo the negotiation process since they face numerous sources of conflicts in their day to day life. The theory of conflict process identifies numerous structural roots of clash within the organisations such as having incompatible goals, when there are differences in peopleââ¬â¢s values,

Observational Method in Psychological Research Essay
Observational Method in Psychological Research - Essay Example One of the characteristic of the observational method of research is that its environment is generally authentic. Even the situation that is studied is subjected to a realistic circumstance that actually generates genuine responses. This characteristic is essential in psychological studies such that the human mind is too complex wherein extensive and intensive observation and monitoring of its activity must be recorded and analysed according to the behaviours observed from the subject of the study. Since the behaviours of the subject of study are natural responses to the actual situations that serve as the one of the factors and conditions being studied. Observational methods enable researchers and practitioners to identify behavioural patterns within the naturalistic contexts at the time during which they actually occur, and, thus, the social validity of these systems is often a strength. (qtd in Lakin, 2005) There are several ways in which observational method in psychological research is delivered. These different approaches in observational method are the participant observation, non-participant observation, structured observation, unstructured observation and naturalistic observation. The observed data gathered through the observation of the various behaviours from each of these approaches involve planned gathering, analysis, and interpretation. As much as the approaches differ from each other, it cannot be avoided that each of the approaches may have an advantage over the others. ("Observational") Depending on the problem of the study and the whole idea of the research, an appropriate observational approach may be identified according to the strengths and weaknesses of each approach. These observational techniques are classified according to the intervention of the observer on the research being conducted. ("Introduction") Naturalistic observation approach is deemed as the most reliable method in studies that involve an observation of specific subjects. ("Observational") The observer in this approach does not intervene in any aspect within the duration of the study. Significantly, the participants involved in the study with whom the behaviours are being observed, do not have an idea that each of their reactions and actions are observed. For all intents and purposes, the researcher is invisible and works hard not to interrupt the natural dynamics of the situation being investigated. ("Introduction") Due to an uninterrupted situation, the participants of the study behave naturally and spontaneously because of the non-intervention and the natural flow of the situation. The researcher becomes more privileged of observing specific behaviours of the participants according to a predetermined set of criteria. For a research study when there is a very limited concept of the research is identified and known by the researcher, this method may also be applicable. The researcher may be able to develop a hypothesis upon observation of the natural situation or event being studied or observed. ("Introduction") However, since the observer or the researcher does not have any control on the situation being studied, he is limited in drawing meaningful conclusions about the causes of a particular behaviour that the subject has exhibited. ("Introduction") Moreover, one of the strongest issues that face naturalistic observation is ethics. Since the participants of the study are not told of the study being conducted, this becomes a violation of
Business Ethics Essay Example | Topics and Well Written Essays - 500 words - 10
Business Ethics - Essay Example principles and values that determine decision making and right or wrong of contextual issues related to business or profession in accordance with ethical problems such as issues relating to human rights, privacy, discrimination, sexual and other types of harassment, performance evaluation, hiring, firing, safety, security, etc. Immanuel Kantââ¬â¢s principles to explain theory of ethics of duties strongly advise three aspects of ethics: consistency, which everyone else also should follow and can achieve; human dignity, which every individual deserves under every situation; and universality, for all actions and human beings should be acceptable by all (Crane, A & Matten, D; 2007). Ethical problems of sexual and physical abuse have been troubling our communities for many centuries. Even today evidences of child abuse and sexual violence against women are prevalent among all groups and levels of people. A recent lawsuit was filed against a popular African-American preacher for molesting a 15-year old girl and sending lewd text messages to another girl. Many such charges were levied against him in the past too (Allen, B; 2009, 21 May). This depicts the disadvantaged status of the female gender even now. This kind of horrifying violence, systematic discrimination and human right abuses leave damaging effects on the society such as physical trauma, emotional trauma, low self-esteem, and psychological disturbances. Professionally, such behavior causes undesirable violation of code of conduct. Unsafe working conditions pose high risk for health problems and hazardous events. One such violation was reported by an army employee at Lockheed Martin plant who suffered injuries as a result of exposure to toxic chemicals. His appeal for justice at the California Supreme Court did not help as four out of seven justices were stake holders in this oil company (Editorial board; 16 Jan 2008). These health problems could lead to changes in human genetic systems that may
