Download file to see previous pages An example of content analysis as a research method is demonstrated in the work of Pfau, et al. (2005), in which they review the effect of the embedding of journalists in the military units involved in the invasion and occupation of Iraq on the tone and message displayed in television news reports. Content analysis was conducted of television news reports aired on four major networks (ABC, CBS, CNN and NBC), and the results were compared based on whether the coverage for each report depended upon embedded or non-embedded journalists.
Pfau, et al. (2005), indicated that embedded news sources displayed an overall tone that was more favorable toward the military in general and depicted military personnel in a more favorable light. Embedded sources tended to use greater levels of episodic frames, eliciting more positive relational cues. By contrast, unilateral or non-embedded sources tended to minimize the use of episodic framing, and tended to depict the military as a whole, as well as individuals in the military, in a less positive tone. As an aside, the study also found uniform indications that the news stories of the initial invasion and early occupation were more positively reported and employed greater episodic framing than the stories about the Iraq occupation as it drew on.

questioning, advising, informing, etc.) and in the tone and structure of the presentation. Multiple systems can be applied to the same data over time, as well, allowing additional analysis and investigation.
A striking example of a longitudinal study can be found in the work of D'Angio et al. (2002), in the 15 year follow-up of children born severely premature and treated with surfactant therapy. An initial pool of 213 infants born at ages prior to 29 weeks of gestation across a three year time span (1985-87) had shrunk to a field of 132 of which 127 were evaluated cross a three year span (1992-95), and 126 were re-evaluated in 2000. At each point, the child's physical and mental conditions were evaluated as was the amount of neurodevelopmental compromise.
D'Angio, et al., indicated that 21% of the 127 evaluated at primary school age showed symptoms of at least one severe disability, while 32% were placed in special needs classrooms and 19% showed general cognitive indices below 70. By the time of the secondary school-age follow-up evaluation 41% of the children had no physical or educational impairment, whereas 19% showed at least one severe disability. 15% of the children at both evaluation times were diagnosed with cerebral palsy. D'Angio, et al., concluded that even with surfactant therapy, children born prematurely remain at high risk for neurodevelopmental compromise and significant percentages of these children will require special educational services. Of added note is the fact that the strongest predictors of adverse outcomes related not to the gestational age at birth, but rather to socioeconomic status and presence of neonatal intraventricular hemorrhage.

..., training only motivates employees when they are at the level of self-actualization and have achieved all other motivational levels. So, MD should first see that all employees or the ones he is trying to target have reached the level of self-actualization otherwise theirs is not point in spending so much for the training session and other method of motivation could be implied so that employees work to meet the organization objectives. For example, this money of $250,000 could be spent on giving financial security to employees who are on that level of motivation hierarchy as suggest by Maslow. They can also be used to create pension funds for the employees to make their futures secure. They can also be used to organize other social events...

Research methods (inferential methods)

It is possibly influenced by the intervening variable as well.
Unit of Analysis: Whereas the independent variable is nominal and can only take the value of either Science or otherwise, the dependent variable is ordinal. This can be divided into a five point scale from strongly agree to strongly disagree. Since the response to this study and the assessment of the study is on individuals, this has to be looked at as individual cases. The dependent variable can become continuous while interpreting.
Sampling: The sampling size can be a larger fraction of the population because the target population is smaller. Of the science graduates nearly 20% of them can be taken up as samples. Only then the results will also be dependable...

Descriptions of methods used to measure

... of the patient's bridge of the nose. Let's say that this value is 30mm for example. This is the monocular PD for the right eye. 3. Finally the doctor directs the patient to look at his or her right eye and notices where the reflection lines up with the PD ruler. Let us say that this value is 62. To obtain the Monocular PD for the left eye, the doctor is to subtract the value obtained from the step 2, with the value obtained here (62-30= 32). The monocular PD for the patient's left eye is therefore, 32mm. Then, like in the previous method, the near monocular PD is measured: 1. The doctor follows steps 1 and 2 for distance monocular PD. 2. Then the doctor glances over and sees where the reflection in the patient's left eye aligns with the PD...

... to show the comparison between the two groups. Experimentation is the best method of research because it proves results after experimentation process. Experimentation establishes a cause and effect relationship as all variables get controlled. The relation between one independent variable and another dependent variable in experimentation is correlation. For example, if psychologists were to examine the relationship between the number of hours students spent playing video games and student grades, the assumption would be that as children spend a lot of time playing computer games, their grades became poorer by the day. This is a negative correlation (Goodwin, 2009). Conducting research on correlation assist in conclusion of the assumptions...

Two Descriptions

...Descriptive Essay A Woman From my kitchen window, one night I saw a beautiful woman jerk back her rain sleeked coat with such ferocious energy that people crossing the road turned around to stare at her. Rain drops drizzled off the brim of her black velvet hat. I love the rain but unfortunately tonight, the rain reminded me of a cold December night I had buried my father. I watched her walk gingerly on the damp slippery street, rain droplets on her face glistened in the street lamp light giving the impression that she was crying silently. She lifted her face to the sky and I followed her gaze to the moon faintly peeking from in between the dark clouds. With tears of grief in my eyes, I looked helplessly at the pale moon. Imagining my...

Research Methodologies and Their Application to Counseling

Data must be subjected to the thinking process in terms of ordered reasoning.

Descriptive Research describes and interprets what it is. It is concerned with conditions of relationships that exist; practices that prevail; beliefs, processes that are going on; effects that are being felt, or trends that are developing.

The process of descriptive research goes beyond mere gathering and tabulation of data. It involves the elements or interpretation of the meaning or significance of what is described. Thus description is often combined with comparison and contrast involving measurements, classifications, interpretation, and evaluation.

In other words, descriptive research may be defined as the purposive...

Cultural History Versus Political History: The Varying Methods of the Two Fathers of History

Even though they have these similarities and have both been bestowed with the same title, these two historians drastically differed in their approaches.

Herodotus had another title bestowed upon him; he was also called the “Father of Lies.” Much of what is known of him has been gathered from his own writings as few other sources are available from his actual life. It should also be noted that the veracity of this information is in question as Herodotus was known to invent much in his own work, and it was sometimes the practice in Ancient Greece to attribute events from the life of one person to another; for instance, it has been questioned if the accounts of Herodotus’ exile are only due to the fact th...

Effective Methods of Teaching Anatomy

Herein, comparisons will be made to highlight the differences in using anatomical models for study versus self-directed (usually textbook) learning. As well, the use of tutors as an advantage in the medical classroom will be discussed.

Some students are hands-on learners. For them, three-dimensional (3D) anatomical models are effective. “Exploratory tools enable users to investigate structures in ways not possible in the real world” (Implementing, para. 3). These 3D models can represent just about any part of the human body. Models are available of small structures, like the head, or of the entire human skeleton. Models of the entire human body can also be purchased. Some of them even have removable parts so...

Developing a Research Base for Intravenous Peripheral Cannula Resites

Two hypotheses were tested in this paper. There are two groups that were compared in the paper. The control group has participants who follow the three-day cannula re-site protocol currently employed in most hospitals. The intervention group would only have cannula re-sites if their medical condition demands it. One of the hypotheses of this paper states that the control group would have more unplanned IV cannula re-site than the intervention group. Secondly, it also states that the cost of total cannula re-site of the control group would be higher than in the intervention group.
A randomized controlled trial was employed for this study. This was very much appropriate for this type of study. According to Pildal, et al (2005),...

Analysis of the Methods of 3 Research Papers about Child Abuse

Research ethics was maintained as the identity of the individuals participating was kept secret. As far as the validity of the study was concerned, the researchers attempted to use content validity in order to get an accurate response. The content validity focused on measuring off the ethnicities and gender percentages within the area and attempting to get a random sample of individuals via the phone. Their approach to random calling allowed for a significant random sample in the study. There were a few issues, however, with this type of approach. Those answering the phone sometimes were not always the desired individual, and not all of the desired people were surveyed. Different replacements did have to be used, and the attempt w...

Using Computers to Teach Mathematics is Better than Traditional Methods

...Using computers to teach Mathematics is better than traditional methods Computer technology has changed the face of education, and is a useful tool in the teaching of other subjects as well with Mathematics being no exception. Various calculating devices have long been used in Mathematics, but the computer offers an even greater potential. Some teachers are reluctant to use computers, for example on the grounds that it is an expensive option and not every child has access to one at home, but its prevalence nowadays means that students should be given the opportunity to use computers in their Mathematics lessons. They have the advantage of being able to make complex calculations much quicker, demonstrate graphical visualisations, instilling...

Alternative Methods of Accounting

Accounting has always been a self-regulated profession. After the 2nd half of the 20th-century changes in accounting occurred due to the influence of private organizations such as the FASB.  In the United States, accountants followed the generally accepted accounting principles (GAAP) to guide their everyday work. Accounting is a discipline that is very strict in its ways and does not welcome change well. In the aftermath of the Enron and WorldCom scandal, the government had to force change with the creation of the Sarbanes Oxley Act of 2002 due to a lack of trust in financial information.
