The effect of a new drug on blood pressure. Testing Research Paper

The effect of a new drug on blood pressure. Testing - Research Paper Example Another reason for using the t-test is because a t-test is normally used when the standard deviation of the population is unknown. In this case we do not know our population. The t-test is also used when the purpose of the study is determining whether there is statistically significant difference between two independent sample groups. In this case the drug and the blood pressure are two independent variables. The z-test is not applicable in this case because it is normally used when the null and alternative hypothesis are stated (Tanner, 2016). In our case the two are not stated. The ANOVA on the other hand is normally used when carrying out a test using three or more variables (Tanner, 2016). In our case, we only have two variables. What would your choice of test depend on? For the test you select, explain your design and your comparison groups. Choosing the type of test to use in a particular study depends on: the type of the variables used either continuous or categorical, the number of variables to use in the particular study either one variables, two variables or three or more variables, the normality, how the variables are normally distributed and the nature of the variables, are they dependent or independent variables. The design in this case will be the number of patients to use in the study. Small number of patients will result in an inaccurate result and using a large number of patients will be risky to their health and lead to waste of resources. One should therefore use not so small neither not so large number of patients.

The period of tulip mania was considered to be a golden age in the Dutch calendar where the prices of the tulip bulbs reached to an unexpected extent (Thompson, 2006). Literature Review and Explanation of Tulip Mania (of the 17th century) At present time, Dutch flower industry comprise about 70% of global flower production and about 90% of global flower trade. From the past time, Dutch flowers were traded to Europe, where the bulbs of flowers were sold with significant amount of prices. Among all the flowers, Tulip flower is significantly interrelated with the life of Dutch people. Dutch people were quite ecstatic about the tulip flowers. From the historical evidence, it can be observed that Dutch people consider tulips as a symbol of fortune in their life. Throughout the period of 1636 it has been observed that the costs of tulip bulbs became extensively which initiated the event, tulip mania (Goldgar, 2007). Historical Explanation of Tulip Mania (of the 17th century) Tulip was first originated in the year 1593, by a botanist named, Carolus Clusius, who carried tulip plant from Constantinople to Holland. He embedded a small garden to investigate the plant for medicinal purposes. Due to certain perceptions about tulip, the flower soon became a fashion icon among affluent people of Holland.

Ethnographic interview - Essay Example They gradually increased the tenure of engagement in these locations and the twentieth century saw the rise of long-term fieldwork with participant observation. According to Whyte, â€Å" When the researcher is living for an extended period in the community he is studying, his personal life is inextricably mixed with his research. A real explanation of how the research was one necessarily involves a rather personal account of how the researcher lived during the period of his study. This account of living in the community may help also to explain the process of analysis of the data†¦ the actual evolution of research ideas does not take place in accord with the formal statements we read on research methods. The ideas grow in part out of our immersion in the data and out of the whole process of living.† (1955, 279) While the above excerpt explains the process of ethnographic research, it also implies some underlying strengths as well as weaknesses of the process. The most evident and likely of all the risks is the idea of ‘going native’ and this would depend on the degree of involvement of the ethnographer with the surroundings. (Schutt, 2006 307) Ethnography helps in developing a user interface where the most important goal is to look at the system from the user’s viewpoint. This method helps in satisfying the needs of the end-user. Thus this method helps in a strong and effective assessment of the unspoken needs of the user. An ethnographer is supposed to accomplish all the tasks and understand all the relationships that integrate to form the job of the user. There is more scope and opportunity for an extensive research since it requires an unstructured form of data collection. The user can carry out his job and communicate even outside the official instructions  or job description. Sometimes when the real end user is not accessible, the ethnographer, owing to the high degree of understanding required in fieldwork, can act like the end-user

Art history response paper - Essay Example The work of the sculptor is usually aided by nature while the painter requires knowledge of how shadows may affect their work. Greater mental analysis and skills are therefore required of painters. The sculptor deals with shapes while the painter deals with the transparent objects. Varchi’s inquiry led to various opinions from different artists. According to Bronzino, both the painters and the sculptors require different types of skills. The sculptors have to be more accurate when it comes to measurements as they cannot cheat on the aspects of measurements. According to Messer Benedetto, painting is nobler as compared to sculpture. Other artists who are in the view that painting is more noble than sculpture includes Pino although Michelangelo disputes the argument that painting is more noble than sculpture since its requires a lot of skills and intellectual efforts. The dialogue between Lauro and Fabio has also been unable to come up with clear answers regarding painting and sculpture. The arguments that have been presented in the article indicate that both painting and sculpture have different unique features. Different skills are required in order for one to become a painter and a sculptor. A lot of intellectual skills are required during the painting as one has to come up with paintings that will be acceptable to the audience. On the other hand, a lot of manual efforts are required when developing a sculpture. This is considering that some of the sculptures are quite huge. A part from the manual efforts, expertise is required in order to ensure that the sculpture does not fall apart during display. However, despite the differences in the requirements, I think that painting is nobler as compared to sculpture. The painters have to be creative and innovative in order to satisfy the audience. On the other hand, the painters are supposed to have knowledge on different elements of art and design

M2A1 - Essay Example Case study one: interpersonal conflict This interpersonal conflict scenario entails two employees of the same organization. The conflict arises from the struggle of promotion and power between the two employees. The cause of the conflict can be attributed to differences in goals, attitudes and values between the two employees. Rick has the informational power to influence the work of John. John relies on interim production reports from Rick in order to accurately prepare summary reports for the entire week. From their working relationship, the accuracy of Rick’s interim reports will influence the quality of output delivered by John to the inventory and marketing departments. The conflict is harmful to the organization since it has led to errors in the summary reports and may also lead to inefficiency of work since John will be forced to retrieve the interim production reports from the main frame computer that has a two day backlog of retrieval requests.

The conflict is shallow since it entails only two employees and no excessive harm has occurred to their overall jobs (Donohue & Kolt, 1994). ... pective position, but their individual differences such as need for power and status, and personality clashes have led to a conflict in their working relationship (Deutsch, Coleman & Marcus, 2006). The second step will entail creating urgency for the need to resolve the conflict through identifying the negative impacts of the conflict towards the attainment of organizational objectives (Donohue & Kolt, 1994). In this regard, the management will identify the errors in the interim production reports, the inaccuracies of the summary reports delivered to the inventory and marketing departments and associated delays in preparation of the summary reports.

Gender and work roles in Society Essay Example | Topics and Well Written Essays - 750 words

Gender and work roles in Society - Essay Example Unlike sex, gender is a socially constructed concept which has many ramifications in the social, political, and economic realms. The social construction of gender roles is responsible for the division the productive labor forces into one which has historically been private and unpaid, known for more than a hundred years as â€Å"women’s work† and another which occurs in the public sphere and his remunerated. Although women have entered the paid labor force in great numbers over the past 50 years, so-called â€Å"women’s work† has relegated women to child-rearing responsibilities, maintaining a home, cooking and cleaning and everything else which has historically been unpaid. Importantly, much of this work, child rearing, cooking, etc is both unpaid and often unappreciated. Historically, men worked outside the home, earning a paycheck and have been the breadwinners of the traditional nuclear family. Since the 1960s women have entered the labor force in incr edible numbers and have begun to earn the respect they deserve for the work that they do. Despite this important change, men still have much more power in our society and it remains structured upon the notion of patriarchy. Accordingly, women face many hurdles to direct employment in the paid labor force in the United States (see Bernbach 33-75). While female participation in the labor force has grown tremendously over the past half-century, women still lag behind men when it comes to getting paid for the hard work that they do. According to the American Department of Labor and Statistics, women on average earned $.80 on the US dollar relative to their male counterparts. From a sociological perspective, what can help account for the disparities women face in the labor force? Discrimination is one challenge women face in the paid labor force and this concept can be defined as the prejudicial treatment of others based upon perceived or real
