Download file to see previous pages When a study is to be conducted, the protection of the human participants or respondents is an issue of primary importance. Essentially, all participants have to be fully aware of their role in the study and what the study is all about. It is important that they are informed of the benefits they can gain from participating in the study as well as the risks that they face. In this particular study by Miyashita, et al. (2006), no particular benefit was provided by the investigators that the respondents stood to gain by participating. The authors also did not provide any risks that the participants face if they agreed to participate in the study. Ideally, the study is supposed to obtain the informed consent of the participants. In this particular study, the respondents were enrolled by the Palliative care units. The respondents were given the freedom to choose on whether not to participate or to participate. It can then be concluded that the study obtained informed consent from the respondents. Additionally, the study obtained both scientific and ethical validity from the institutional review boards of hospitals that were participating in the study.
With reference to data collection, there are independent and dependent variables. The author identified the variables as follows; the general population and the bereaved family were the dependent variables. The independent variables were the age and sex of the respondents. It is worth noting that the authors failed to overtly demonstrate the significance of obtaining the sex of the respondents as its value to the study was not clearly demonstrated. The authors chose to use questionnaire as the sole means of data collection. The authors did not provide a rationale for choosing to use this method of data collection. It would have beneficial for the authors to state for example why questionnaires were chosen over interviews for data collection. Again, using this method solely as the main method of data collection cast some doubt on the reliability of the data obtained. This is because respondents may give information without understanding the purpose of the study and thereby compromise the accuracy of the data (Creswell, 2008). But, by allowing the respondents to choose whether to respond or not to; they prevented any ethical issues from arising. The questionnaires did not request for any form of information that may be directly associated with any particular individual thereby assuring the respondents their privacy. The authors posted the questionnaires on August 2004 and then October 2004 for those who had failed to reply. The participant was expected to receive the questionnaire sent by mail and fill the information if he is willing to participate in the study. He would then post it back to the investigators. The primary objective of the study was to conceptualise the good death dimensions within the Japanese care center. The study also intended to clarify on the significance of each of the components of good death and explore the factors that influence an individual’s perception of good death. The authors used Cronbach’s alpha coefficients and explanatory factor analysis to be able to conceptualize a good death. The factor analysis enabled ...Download file to see next pagesRead More

This research paper was always my weak point. I could never complete it successfully. Still, after I found this particular paper, I understood how it should be done. So, I performed my research afterward and completed the research paper in several hours, instead of months as it was previously.

...?3. The nominal scale is the simplest type of scale. The numbers or letters are just used for the purpose of identification only. A common example isthe coding of males as 1 and females as 2. The ordinal scale arranges the objects according to their magnitude. However, we cannot say anything about the difference between two measurements on the scale. An example can be shoe size. The higher the shoe number the bigger the shoe size. But we cannot say that a shoe of size 8 is twice as big as a shoe of size 4. In the interval scale the difference between two measurements has a meaning. The distances between each internal on the scale is equal. The location of zero is arbitrary in an interval scale. For example, the difference between... The...

Quantative Methods (Statistical Analysis)

..., Pareto Diagrams – amongst other techniques can help in identifying the causes of these variations; and the feasibility of responding to them. A Pareto chart is a chart that maps both the individual categories under survey as well as the cumulative total of the categories. Each category is represented as a bar; and the categories are ranked from the one causing most variation to the one causing the least. The cumulative total is represented as a line graph; and is most often curved to form a concave line. The left vertical axis represents the frequencies and the right vertical axis, the cumulative percentage. The horizontal axis represents the categories under study. The chart thus helps us identify the categories that...

...using the general questionnaire and symptom evaluation forms. The selection of the validity and reliability of the two methods was based on the results of the pretrial. The questions that were evaluated as hard and misunderstood by the participants during the pretrial were corrected by the experts before the actual test or excluded totally from the forms. The two methods are effective for the study sample since, despite the number of questions being relatively higher, the sample size is small (45 participants); hence, the analysis may be quite easier. This research used statistical package for the social sciences in analyzing the data. The chi-square test was used in analyzing the categorical data and...

Her actual identity, and demographic details will remain undisclosed for reasons of confidentiality, and in this assignment, her pseudonym Jane will be used. Although Jane was the patient I was caring for, this incident is related to her mother. In this assignment, no information will be utilized which could violate the healthcare informatics confidentiality issues, such as anonymity, confidentiality, and data protection. This incident is critical in my opinion and interesting since this did not involve the patient. This incident was related to the patient, but...

...and analysis is required for this decision. 2. From the information that has been provided the Mean has been calculated to be 7.55 calls. For the mode however there are two possible answers, 4 as well as 8. This is because they are repeated the most number of times. However, 8 will be chosen as the Mode in this case as it is closer to the mean that has been calculated. The Median for in this case has been calculated to be 7. These numbers are quite accurate and are as expected. These values are all quite accurate, however the median can be considered as the most accurate measure. The Standard Deviation in this case has been calculated as 4.421255. This implies that the number of calls can be 4.421255 ­above or below the...

Critical analysis case study

...1 Introduction This paper describes an interesting case study of how multiple clinical decisions about a medical case study can influence a patient’s life. The case study used in this paper was the one I personally experienced some years before; the patient at the center of this issue faced a life-threatening kidney failure that requires that Peritoneal Dialysis (PD) be carried out on him (Nolph, 1989: pp. 21-28). However, since the PD was not helping his condition that deteriorated gradually, the need for multiple decisions arose among four main components of concerned people—the doctor, the nurses, his family and combined people. This paper reveals how interdependent sub-groups of...
