Female Relationships in Shakespeares Taming of the Shrew...

Female Relationships in Shakespeares Taming of the Shrew and A Midsummer Nights Dream Often in literature, parallels are used to accentuate certain things. William Shakespeare utilizes this tool in both The Taming of the Shrew and A Midsummer Nights Dream. In both of these comedic plays, there is a set of women who are at odds with each other. These relationships can be compared and contrasted in different aspects. In Shakespeares, The Taming of the Shrew the relationship between the sisters Katherine and Bianca appears to be strained with rampant jealousy. Both daughters fight for the attentions of their father. In twisted parallel roles, they take turns being demure and hag-like. Father of the two, Baptista Minola, fusses†¦show more content†¦Petruccio sees dollar signs and rushes forth in grand dress and eloquent mannerisms to court the gracious Kate.

Raymond Carvers A Small Good Thing Essay example - 842 Words

Raymond Carvers A Small Good Thing Raymond Carvers A Small Good Thing, a short story that has to do with the lack of interaction and empathy between the baker, Ann and Howard, the finale where the baker is startled to find out about the childs death, asks for mercy and presents them warm cinnamon rolls telling them that Eating is a small, good thing in a time like this and they are comforted, reveals particular significance of the title in terms of the storys theme. Also, Raymond Carvers Cathedral, a story that starts with an ignorant and rude narrator whose wife has called a blind friend to spend the night at their home and according to Carver, A blind man in my house was not something I looked forward to,(38) has some†¦show more content†¦After the baker takes all the rage thrown on him by Ann, he in return begs for forgiveness and gives the parents what they were lacking, that is food. The baker does all this even though he is alone and virtually makes contact with anybody. In Raymonds Cathedral, certain similarities can be drawn from the thematic content that is revealed in both stories. In Cathedral, the theme is expansive, but the ones that are similar in both stories are communication, and empathy. The communication theme in this story is much more serious than the one in A Small Good Thing, the reason being that the narrator has less or no communication whatsoever with his wife. This is vividly shown in the story where the narrator says When the time rolled around, my wife went to the depot to pick him up. With nothing to do but wait, I was having a drink and watching TV.(41) This deficiency of intimacy, intercourse led the narrator to be ignorant but very thoughtful. However the narrators thoughtfulness did not lead him to understand that his lack of tolerance was much more serious than he knew it was. In A Small Good Thing, as mentioned earlier, after Howard returns home, the baker keeps on calling him and telling him about the cake, but Howard tells him I dont know anything about a cake, Jesus what are you talking about?

Architectural Work Place Designs and Work Behaviors for Apple

Question: Discuss about theArchitectural Work Place Designs and Work Behaviors for Apple. Answer: Introduction In recent years the area of architectural design and use of technology is influencing work designs and employee behaviors. Buildings are constructed in a way that it pushes employees to work towards new limits. Example of such buildings is that of Apple Park, a campus that houses 12000 staff with a vast circular building surrounded with a park, and Nvidia a two storey building. Apple Park is located in Cupertino with a type of Silicon Valleys campuses which makes it to be an emblem of the latest US technology industry craze. Nvidia a chipmaker on the other hand has a two storey office with spaces in its heart that do not allow collisions and interactions of the users (Ording Louch 2017, p.45). Nvidia design represents a Utopia of a wide flat across campuses instead of making users split across vertical floors. Every employee in Apple and Nvidia have own work stations (hot desks) which allows them to gather and huddle when working for a project. The use of hot desks is more cost effe ctive and more flexible. Motivation behind use of utopia flat design campuses and hot desks is on revenue generation originating from employees working collaboratively (Myerson, Bichard 2016, p.24). Several studies findings have justified the use of hot desks as appropriate for working stations. A research conducted by Leesman a workplace research group established that 70% of employees in activity-based workplaces like to huddle in a single desk. That contrasts with the aim of using activity-based work place which was designed for them to move from a zone to another during a working day. Gensler, the architectural firm for Nvidia new building justified in their finding that employees require work stations with less privacy, more collaborations and limited space for working. That is provided by the use of hot desks which is more relevant to what the employees need. The drawback of using hot desks is that it may not be suitable for certain professional works requiring individual efforts instead of collaborations (Ording Louch 2017, p.45). Other jobs require individuals to focus towards work and any migration or open spaces would cause distractions. Changes in technology continue to erode work patterns and it is then appropriate if only they do not re-engineer the behavior of the users. Research questions How does architectural technology craze contribute to redesign of work spaces? What are the factors contributing to the recent architectural technology craze in work spaces? Which office space design configuration is most appropriate for employee working behaviors? What are the challenges facing architectural technology in redesigning work spaces? Literature review Literature review of the article is based on the research questions and will be derived from empirical facts from secondary sources of data. Architectural technologies craze and redesign of work spaces There is emerging craze in architectural technologies for work related spaces. Designers and architects are now tasked to redesign work spaces that innovative. They are focused on achieving goals for creating new working spaces that revolve building of communities, encourage work encounters, and could enhance collaborations. The building sector in US and across the world is developing in a rapid speed there is need to adhere to strict building and construction codes. Differential building of co-working spaces as emerged as one of the fast growing areas in the building sector. Architectures and designers are competing to provide the best office structures (Myerson, Bichard 2016, p.24) Innovation spaces in architectural designs are signs of demographic, economic and cultural forces influencing office structures developments. The dynamic changes in innovation are transforming office structures into flexible locales, open enough to host different professionals and disciplines. Changes in demographics in the work place are the leading cause of changes in office structures designs. Designers are tasked with innovative ways to ensure different workers needs are met for the benefit of the institution (Chappell Dunn 2015, p.45). Factors contributing to the recent architectural technology craze in work spaces The architectural work spaces have changed over the last 10 years due to different reasons. The first reason comes from convergent sharing of ideas and opinions from different sectorial areas. Different disciplines and professionals are currently contributing to the latest architectural building designs. Committees are formed from different sectors among them architecture personnel to develop suitable work spaces for their clients. Today, external sources for example the RD laboratories are producing commercialized architectural designs which they sell to different clients. The second factor is that now days architects and designers are competing to deliver competitive and breathtaking designs for their clients. Innovative use of technology currently contributes to 80% of the emerging trends in architectural technology craze in developing work spaces (Latham 2016, p.45) The third factor emerges from those using the work space democratically contributing significantly to current design. Architectural designs are distancing from dictation from architects and leaders of the organization (Giachetti 2016, p.23). The users are given opportunity to state the kind of design they expect to have for their work spaces. It has changed how employees are empowered and elevated to define the nature of work space that supports their ambitions and needs (Lifschutz 2017, p.34). The current architectural designs have become a cutting edge in integrating employee and organizational cultures, ambitions in supporting work space designs that are mutually suitable. Architectural work space configurations and employee working behaviors Private offices are examples of office space designs that architectures design for office use. Private office workplaces offer the largest amount of security of all office conditions. Private offices workplaces likewise furnish representatives with spots to privately hold meetings and have their own particular conferences with colleagues. In many work environments, private office workplaces exist however restricted to abnormal state administrations. It is very costly to have a private office spaces for each worker (Deasy, Newell, Mware 2015, p.45). In any case, offering private office workspaces for representatives to share can go far in consuming resources. As per The Washington Post, around 70 percent of U.S. workplaces take after the open office organize with no or little segments. The beginning of this office space designs absolutely originated from the technology organizations in Silicon Valley, which gloat that open office designs offer unparalleled connection and straightforwardness (Sailer, Pomeroy Haslem 2015, p.253). What started on the West Coast spread the nation over and into organizations in all businesses. While these office floor designs help expand organization space at bring down costs, they can contribute significantly to profitability. The cubicles are example of office space designs configurations where smaller partitions are created to lessen the open spaces created in an open layout office. It is a cost effective method of creating offices and architecturally they were developed from open office plan layouts. They possess numerous drawbacks; employees under the cubicles noise is still a concern, visual distractions is another problem, and another problem is normal movement can be a major disruptions (Hatch 2017, p.132). Certain cubicles are made more attractive by designing meeting points for the employees to breakdown the monotony of open cubicles. Co-working space is a type office space designs configurations applied by architectures. The designs bring diverse groups of workers, professionals in a shared environment. A study by Harvard review shows that employees in co-working spaces are successful than those found in regular offices. The co-working spaces are available to employees at all times (Ching, Binggeli 2018 p.45). They contain numerous working spaces that employees can share tables, resources and share ideas effectively. Challenges facing architectural technology in redesigning work spaces The changing social behaviors and organizational intentions has become a challenge that is contributing to how work space is designed. Architects and designs are largely affected because they need to follow social patterns which are dynamic. Balancing between innovation and design flexibility is another challenge for architects and designers. Organizations are focused on developing work spaces that are flexible to the current and future needs which is challenging. Flexibility requires thinking through all aspects of design, available resources, technology used, current and future needs. The demand for flexibility has made architectural technology in development of work spaces a complex endeavor (Wyoma VanDuinkerken Karen MacDonald 2013, p.248). The changing work pattern and policies for organizations is another challenge to architects and designers. The rate in which changes are done in organization and global changes makes organizations to review their designs for work spaces. A number of architects are complaining over the highly curtailed life of architectural technology designs for work stations. Another challenge is that in collaborative architectural technology designs for work spaces require sectors to communicate effectively on tacit information (Duffy, Cave Worthington 2016, p.45). But the information is found to be undocumented, unstructured, and more experiential that require rich communication techniques. The state and government policies that change town mapping and designs contribute to reshuffling of work space, changing of designs and arrangement of work spaces becomes an occasional challenge for architectural technology designers.

Photosynthesis Coursework Essay Example

Photosynthesis Coursework Essay The aim of my experiment was to determine whether or not the intensity of light would affect the rate of photosynthesis in a plant. To do this, I placed a piece of Canadian pondweed in varying light intensities, and observed the amount of oxygen being given off. I used Canadian pondweed because of its unusual quality of giving off bubbles of gas from a cut end, when placed in water.IntroductionPhotosynthesis occurs only in the presence of light, and takes place in the chloroplasts of green plant cells. Photosynthesis can be defined as the production of simple sugars from carbon dioxide and water causing the release of sugar and oxygen. The chemical equation for photosynthesis can be expressed as:(light)6CO2 + 6H2O à ¯Ã‚ ¿Ã‚ ½ C6H12O6 + 6O2 (in the presence of chlorophyll)The fact that all plants need light in order to photosynthesise has been proven many times in experiments, and so it is possible to say that without light, the plant would die. The reason that light intensity does a ffect the rate of photosynthesis is because as light, and therefore energy, falls on the chloroplasts in a leaf, it is trapped by the chlorophyll, which then makes the energy available for chemical reactions in the plant. Thus, as the amount of sunlight, or in this case light from a bulb, falls on the plant, more energy is absorbed, so more energy is available for the chemical reactions, and so more photosynthesis takes place in a given time. There are many factors, which affect the rate of photosynthesis, including light intensity, temperature and carbon dioxide concentration. The maximum rate of photosynthesis will be constrained by a limiting factor. This factor will prevent the rate of photosynthesis from rising above a certain level, even if the other conditions needed for photosynthesis are improved. It will therefore be necessary to control these factors throughout the experiment so as not to let them affect the integrity of my investigation into the effect of light intensity .PredictionsI predicted that as the intensity of light increased, so would the rate of photosynthesis. Furthermore, I hypothesised that if the light intensity increases, the rate of photosynthesis will increase at a proportional rate until a certain level is reached, and the rate of increase will then go down. Eventually, a level will be reached where an increase in light intensity will have no further effect on the rate of photosynthesis, as there will be another limiting factor, in this case probably temperature.Preliminary workInitially, to ascertain a suitable range of distances at which to record results for my experiment, I did a preliminary investigation in which I recorded the number of bubbles of oxygen given off in a given time at various light intensities. To alter the light intensity, I placed a lamp at various distances from the plant. I also therefore needed a way of accurately measuring the light intensity, and I did this using a photometer. I recorded the lux reading (unit of light intensity) at each distance. I got the following results:Results of preliminary experimentDistanceLight intensityNo. Bubbles(cms)(lux)4555124080123511013301491425208162031018155902010945215101521Although this is a very quick, simple and efficient way of obtaining an idea of the trends for the graph, and the boundaries for the measurements, this experiment was not in itself in my opinion accurate enough to be the basis of my main experiment. This lack of accuracy was mainly due to the fact that by simply counting the bubbles, I was relying on each bubble being exactly the same size, which they clearly were not. The preliminary experiment will, however, give me a best fit curve to which I can compare my main graph, and also points at either end of my results at which it is clear to see light intensity has little or no effect. Here, it was in fact at a light intensity of around 950 when it seems that another factor such as temperature or carbon dioxide concentration has become a limiting factor. In my main experiment therefore, it will not be necessary to take readings above this point. It also shows that while my outer limits are justified, it would be better to take more readings between the distances of 10 and 20 centimetres, as the distance between the points is large at this point, and so I have decided to take readings at the following distances: 5, 10, 12, 14, 16, 18, 20, 25, 30, 35, 40 and 45, cmà ¯Ã‚ ¿Ã‚ ½s.MethodInput variables à ¯Ã‚ ¿Ã‚ ½ light intensity is to be varied by increasing and decreasing the distance from the light source to the plantOutput variables à ¯Ã‚ ¿Ã‚ ½ volume of oxygen produced (rate of photosynthesis) is to be measured by finding the volume of oxygen produced in a minute, and thus finding the rate of photosynthesisControl variables à ¯Ã‚ ¿Ã‚ ½Light wavelength (colour) à ¯Ã‚ ¿Ã‚ ½ light energy is absorbed by the pigment, chlorophyll, in the leaf. Chlorophyll easily absorbs blue light, in the 400-450 nm range, a nd also easily absorbs red light, in the 650-700 nm range. However it does not easily absorb green or yellow light, rather it reflects them, decreasing the amount of light absorbed, and therefore the rate of photosynthesis. This can easily be controlled, simply by using the same lamp throughout the experiment.Carbon dioxide concentration à ¯Ã‚ ¿Ã‚ ½ This can affect the rate of photosynthesis, since if there is too little CO2, it can become the limiting factor, thus impeding the viability of the experiment. In this case, as long as the experiment is done over a short period of time, the amount of carbon dioxide used up by the plant will not be sufficient enough to cause the carbon dioxide concentration to become the limiting factor. If my experiment were to be performed over a longer period of time, for instance 24 hours, I would add a fixed amount of Sodium hydrogen carbonate to the water, thus ensuring a large enough supply of carbon dioxide.Water availability à ¯Ã‚ ¿Ã‚ ½ water i s also required in the photosynthesis reaction, and when it is lacking, the plantsà ¯Ã‚ ¿Ã‚ ½ stomata close to prevent further water loss. This closing of the stomata cells also leads to little carbon dioxide being able to diffuse through. Clearly, in a water plant, like the pondweed, as long as the plant is fully submerged in water at all times, this will not be a problem.Temperature à ¯Ã‚ ¿Ã‚ ½ Enzymes are used in the photosynthesis reactions of a plant. Therefore, temperature will increase the rate of photosynthesis, until a point at which the enzymes denature. Although performing the experiment at a temperature slightly higher than room temperature, perhaps 25à ¯Ã‚ ¿Ã‚ ½C, would have a positive effect on the accuracy of the readings I took, as it would reduce the percentage error, by increasing the volumes, I decided that the inaccuracy of maintaining a constant temperature would outweigh any advantages. I am therefore going to perform the experiment at room temperature, chec king the temperature frequently, in case the heat given off from the light should slightly raise the temperature, in which case I shall simply refill the beaker with more water after each experiment.MethodApparatus listDesk lampAudus apparatusCanadian pond weedKnifeClampPond waterThermometerTest-tubeBeakerCold waterStopwatchCut a stem of Canadian pondweed of about 3cm in length. Fill a test-tube with pond water, and place it in a clamp, and then in a large beaker of cold water. Connect the end of the pondweed to the Audus apparatus. Insert a thermometer into the beaker, and record the temperature at the beginning and end of each experiment, merely as a precaution against a significant rise in temperature, which is not expected. Set up a lamp at a set distance from the plant, ensuring that this distance is from the filament of the lamp to the actual pondweed, rather than the edge of the beaker. The light intensity was measured in the same way as described in the preliminary experimen t, and assumed to be the same at any point at any particular distance. When bubbles are being produced at a steady rate, clear any previous bubbles from the tubing by moving the syringe. Start the stopwatch, and wait for 1 minute. Move the bubbles, which have been collected at the bend in the tubing to the part of the tube with a scale. Find the length of the bubble collected. Repeat for all other readings, and then repeat all readings a second time to get an average result for each distance.Audus apparatusUsing the described method, I found the following results:Results for main experimentDistanceLight intensitylength 1length 2average length(cm)(lux)(mm)(mm)(mm)510153.53.53.5109453.53.53.512770433.5146393.53.53.51650033.53.25183953332031023.52.75252081.52.51.75301491.51.51.53511011140800.510.75455500.50.25Although, because I was using light intensity as my variable, I did not need to record the distances as well, I did, simply to use them as a marker for each result, so that I only had to record the light intensity once at the beginning and from then I just had to align the lamp at the correct distance each time.AnalysisMy graph was in the form of a best-fit curve. I drew it as a curve rather than a straight line because of the clear pattern of the points. This meant that the rate of photosynthesis increased as the light intensity increased. This was because photosynthesis is a reaction, which needs energy from light to work, so as the amount of energy available from light increased with the rise in light intensity, so did the amount of oxygen produced as a product of photosynthesis.My graphs showed that the relationship between the light intensity and the rate of photosynthesis was non-linear, as both graphs produced a best-fit curve. However, as I expected in my hypothesis, it does appear that for the very first part of the graph, the increase in rate is in fact proportional to the increase in light intensity (i.e. a straight line) and I can show this by ta king some readings from the graph:Light intensity Rate of photosynthesis(All increase by the 100 1 (mm/min)same factor) 150 1.5 (mm/min)200 2 (mm/min)From these results, I am able to say that an increase in light intensity does certainly increase the rate of photosynthesis. The gradual decrease in the rate of increase of the rate of photosynthesis (the shallowing of the curve) can be attributed to the other factors limiting the rate of photosynthesis. As light intensity increases, the photosynthetic rate is being limited by certain factors, such as carbon dioxide and temperature. These factors do not immediately limit the rate of photosynthesis, but rather gradually. As light intensity increases further, so the rate of photosynthesis is being limited by other factors more and more, until the rate of photosynthesis is constant, and so is almost certainly limited in full by another factor.Overall, both graphs and my results support my predictions fully. My idea that the rate of photos ynthesis would increase with light intensity was comprehensively backed up by my results. This is because a higher light intensity involves a greater level of light energy, which can then be transferred to a special protein environment designed to convert the energy. Here, the energy of a photon is used to transfer electrons from one chlorophyll pigment to the next. When enough energy has been gathered at a reaction centre, ATP can be synthesised from ADP. The oxygen collected in the experiment is in fact the by-product of this reaction, and so it is clear to see that the more light energy, the more ADP is being converted into ATP and more oxygen is produced as a result.EvaluationAlthough I feel that my experiment was sound overall, I thought there were many points at which the accuracy was not perfect. As I have already stated, my preliminary experiment was not accurate enough to justify being used as my main experiment, mostly due to the fact that I was relying on all the bubbles being the same size, which they clearly werenà ¯Ã‚ ¿Ã‚ ½t, however many of the smaller inaccuracies also apply to my main experiment.Firstly, the distance between the light sources and the Canadian Pondweed were not measured to a very high degree of accuracy, especially when you note the fact that the distance should have been measured exactly from the filament of the light bulb to the centre of the plant, and it is possible here to find a percentage error. I estimate that the error could have been up to 0.5cm and I will find the percentage error for the largest and smallest reading using this estimate:Percentage error = possible inaccuracytotal reading% error distance10 5cm1 50cmIt is clear to see that the percentage error is much less for the larger distances. Although I was not actually using the distances as part of my results, I used them as a marker for where the lamp was placed each time, as I assumed that the light intensity would be the same each time at a particular dista nce. Therefore, any inaccuracies in measuring the distances, i.e. if a distance was slightly different when doing the actual experiment from the distance at which I earlier measured the light intensity, an error would ensue.The second major inaccuracy was in measuring the volume of oxygen given off.When reading the syringe there could have been an error of 0.25mm, and again it is possible to find a percentage error.% error volume3.57 7ml50 0.5mlFor the smallest volumes this is clearly a massive error, and to improve this, it would be necessary to do the readings over a longer period of time, therefore increasing the volumes, and in turn reducing the percentage errors.Another error would have been due to background light in the vicinity. We tried to reduce this error by closing all blinds in the laboratory, but due to practical reasons, we could not all perform the experiment in a separate room, and we therefore experienced light pollution from other studentà ¯Ã‚ ¿Ã‚ ½s experiments. This would have had a very marginal effect on my results as a whole, but to eliminate this problem completely, it would have been necessary to perform the experiment in a totally dark room.A further inaccuracy was in the heat generated by the lamp. As I have earlier described, temperature has a very noticeable effect on the rate of photosynthesis, and so any increase in the temperature of the pond water would have had serious effects on the accuracy of my results. To ensure this did not happen, I monitored the temperature of the water before and after every reading, to check that the temperature did in fact not rise. It turned out not to be a problem, as over the short period of time taken by my experimental readings, the temperature did not rise at all. However, if I were to extend the time of my experiment to 5 minutes for each reading for example, which would have the effect of reducing other percentage errors, I would have to find some way of keeping the temperature constant. O ne way of doing this would be to place a perspex block between the lamp and the plant, which would absorb most of the heat, while allowing the light energy to pass through.As I mentioned in my planning, carbon dioxide concentration could have been an error in the experiment, however, I feel that due to the short period of time taken, there is very little chance that the concentration would ever have been so low as to have become the limiting factor. Again if I were to carry out the experiment over a longer time period, it would have been necessary to add sodium hydrogen carbonate to the water to increase the carbon dioxide concentrations.The last inaccuracy, though a small one, was in the time keeping. The main problem here was in when to begin the minute. If for one reading, the minute was started just after one bubble had been produced, and in another reading it was just before, this could have had a negative effect on the accuracy of my results. I therefore ensured that in each c ase I started the stopwatch just after a bubble had been produced, thus heightening the accuracy.Overall, I felt that due to the small volumes of oxygen involved, my experiment was not as accurate as it could have been, however I believe it was accurate enough to support and justify my hypotheses. Improvements could have been made as I have stated, mainly by simply increasing the time taken. However, due to practical time constraints in taking the readings for my investigation, and some consequential problems relating to time extension, I could not in fact make these adjustments. The other obvious way of increasing the reliability of my results would be to take many repeat readings and find an average.To extend my enquiries into the rate of photosynthesis, I could perhaps try to link in some of the other limiting factors to the same experiment, as well as investigating them in their own right. It could also be interesting to explore the effects of coloured lights on the rate of phot osynthesis, which could lead to the question of whether or not other types of light, such as fluorescent lights or halogen lights, would have a different effect on the rate of photosynthes
