Interaction of Variables
Overeating: Interaction of variables
As obesity rates climb, there has been a proliferation of research to determine what weight loss methods are effective and ineffective. However, human beings do not live in laboratories, and multiple factors can affect their eating and exercise behaviors. Of course, some studies attempt to meticulously track how many calories subjects consume and how much activity subjects engage in over a specific period of time. But these studies are invariably of short duration, and cumbersome to administer. The result is that experimental and observational data on what promotes weight loss is often contradictory and frustrating for dieters. Overeating is caused by an interaction of multiple variables, including total calories consumed, perceptions of certain foods, and emotional 'triggers' for overeating that are not always immediately apparent.
Conventional wisdom, even amongst scientists, has been it is not what subjects eat but the amount of calories that they eat that are significant in terms of weight loss. However, some studies indicate that overeating...
According to the pioneering Duke University Medical Center, a leading research center in the treatment of obesity, in a study of dieters randomly assigned to high-protein, low-carbohydrate diet plans vs. those assigned to standard low-calorie plans, the low-carb dieters lost "26 pounds...lost more body fat, and lowered their triglyceride levels and raised their HDL, or good cholesterol, more than the low-fat dieters," who lost an average of only 14 pounds and did not show as significant an improvement in lowering their triglycerides and raising their HDL (Study: Low-carb diet more effective than low-fat diet, 2004, Duke Medicine News and Communications).
However, in a recent Journal of the American Medical Association study in which "25 young, healthy men and women were deliberately fed nearly 1,000 excess calories a day for 56 days, but with diets that varied in the amounts of protein and fat," it was found that all gained weight and in fact the low-protein dieters gained the least weight, although they did lose the most lean body…

Interaction Hormones Behavior, Interactions Affect Determination Gender Identity There are two important distinctions to be drawn, the biological determination of a human being's sex and the gender identity. The former cannot be denied as it is manifest and the complete distinction between a male and female in terms of organs and biological build up is manifest. The perception of an individual regarding who 'he' or 'she' is being defined as 'gender

The effect of high school socioeconomic status on the predictive validity of SAT scores and high school grade-point average. Journal of Educational Measurement, 48(2), 101-121. African-American (AA) and Latino students underperform other racial groups during their first year of college if SAT scores are used in the prediction formula. The reasons for this are unknown, although socioeconomic status (SES) is
The first flow of influence is disarming, the process of omitting any signs of power or control on the part of the seller. Second is liking, or how rapport is established and relationships are trigger with strangers. Third is distinctiveness, which refers to the degree that the seller's approach differs from others to which the buyer has been exposed. Williams (1998) suggests that firms who want to move from traditional
Interaction of Variables. Influence upon a psychological phenomenon One of the most alarming trends in psychology is the increase in diagnoses of autism. No singular cause has yet to be determined to explain why autism rates have increased so rapidly, although an increase in efficacy of screening, most scientists believe, cannot entirely explain the spike in cases. A correlation between the ages of the mother of children with autism has been

Cho and Song (2015) examine the determinants of whistleblowing behaviors in public administrative positions in their study by basing their approach on the work of Miceli and Near, who "argued that proactive personality, less co-worker invalidation, and leverage in the specific situation lead to whistleblowing" (p. 450). However, in their research, Cho and Song (2015)
Psychological Research and Patient-Practitioner Interaction The work of Like and Zyzanski (2002) reports that patient-practitioner transactions in the ambulatory setting have gained in importance in the research as there is "empirical support for our anecdotal, common-sense notions that clinical encounter experiences are a major determinant of outcomes such as the patient's satisfaction with the encounter. The study is reported to examine the issue of patient-physician encounter and asks the questions of:
