Richard Gwyn proposed that Canada’s political integrity was near perfect up until 1975, where political transgressions became prominent in the news. What Gwyn fails to note is the many smaller transgressions that have surfaced prior to 1975, which may not fall into the category of noteworthy (Gibbons & Rowat, 1975). The empirical evidence that must be stated with response to Canada’s political corruption is what is considered by many to be political integrity. What questions must also be answered; are what is considered shabby politics? Is...

Is Accounting a Measurement Science

...the subject of a critical review,the intensity of which is increasing as time goes by. Somehow, both within and without the accounting profession, there is a feeling of dissatisfaction with the information generated by the accounting process. Such dissatisfaction is leading to questions about the fundamental bases of Accounting. The practitioner claims to identify,collect,measure,record,analyse and report financial data useful for a variety of purposes. Unfortunately, recent financial turmoil emanating from some of the uses applied to accounting reports is causing accountants and other stakeholders to question the foundations of accounting. Some ask questions like is Accounting a Science or Art? If it is a science, what is its foundation in Science? Are their theories guiding the focus of accounting scholars? Are these theories the result of empirical findings and observations? Are the findings the outcome of diligent and rigorous measurement of phenomena? Does accounting measure any phenomena? Is the accounting phenomena amenable to measurement? Inshort is Accounting a measurement Discipline? Scholars are therefore re-examining the foundations of accounting to determine its suitability as a Science. A Science Discipline is founded on theories which are prediction of phenomena. These predictions are possible because rigorous and precise measurements of phenomena is achieved using instruments or tools. Therefore measurement is critical to any science discipline.

Factors Affecting Junior High School Students' Interest in Physics

...Journal of Science Education and Technology, Vol. 15, No. 1, March 2006 ( C 2006) DOI: 10.1007/s10956-006-0355-6 Factors Affecting Junior High School Students’ Interest in Physics1 Ricardo Trumper2,3 We report the results of a study on students’ interest in physics at the end of their compulsory schooling in Israel carried out in the framework of the ROSE Project. Factors studied were their opinions about science classes, their out-of-school experiences in physics, and their attitudes toward science and technology. Students’ overall interest in physics was “neutral” (neither positive nor negative), with boys showing a higher interest than girls. We found a strong correlation between students’ “neutral” interest in physics and their negative opinions about science classes. These findings raise serious questions about the implementation of changes made in the Israeli science curriculum in primary and junior high school, especially if the goal is to prepare the young generation for life in a scientific-technological era. A more in-depth analysis of the results led us to formulate curricular, behavioral, and organizational changes needed to reach this goal. KEY WORDS: interest; junior high school students; physics. INTRODUCTION As noted by Osborne et al. (2003), “the investigation of students’ attitudes towards studying science has been a substantive feature of the work of the science education research community for the past 30–40 years” (p. 1049). Its importance is emphasized...

According to World Health Organisation, WHO, Physical activity is defined as any bodily movement produced by skeletal muscles that requires energy expenditure, (WHO, 2015). There are various concepts on health and wellbeing and remains a complex subject but according to Claude Bouchard, Health is a human condition with physical, psychological, social dimensions, each characterized on a continuum with positive and negative poles. Positive health is associated with capacity to enjoy life and withstand challenges; it is not merely the absence of disease. (Bouchard, 1990). Wellbeing is often described as a sense of good feeling and functioning well, this includes having a fair share of material recourses, influence and control, sense of meaning, belonging and connection with people and the capability to manage problems and change.

Yoga: a Path to Healing and Recovery

...strength, and flexibility from its practice (The Health Benefits of Yoga, 2012). Nevertheless, is yoga everything it promises? Are people healthier physically and mentally? Are there dangers to practicing yoga? Is it safe? (Bee, 2012) Research suggests that yoga is a highly therapeutic means of exercise because it provides beneficial physical results, leads to positive psychological effects and poses few risks. Physical Benefits of Yoga Yoga bestows several physical health benefits such as lowering blood pressure, lowering heart rate, decreasing blood glucose levels, and mitigating the effects of stress. Cade’s study found that adding yoga reduced resting blood pressure by 4 points compared with the control group (Cade, et al., 2010). McCaffrey and Hatthakit’s study found systolic and diastolic blood pressure as well as heart rate all significantly declined over an 8-week yoga intervention (McCaffrey & Hatthakit, 2005). Hedge’s study shows the patients who received yoga classes showed significant reduction in Body Mass Index (BMI), better glycemic control, and lower stress indicators and increases in anti-oxidants (Hedge, et al., 2011). Ross and Thomas’ review examined other studies and found yoga interventions to be equal or superior to other forms of exercise in all health indicators except in...

...JOURNAL ARTICLE CRITIQUE of VandenBerg, Mary L. "What general revelation does (and does not) tell us." Perspectives on Science and Christian Faith 62.1 (2010): 16-24 Introduction: The goal of this work is to exam and critique an article about Reformed theology, an area regarding the relationship between the physical world and the Bible, and discussing common misconceptions regarding the harmonization of the Bible and the natural world. This review will cover a quick summation of the article, followed by a critical analysis about its main ideas and points. The author, Mary Vandenberg, believes while the Reformed theological tradition’s basic idea of harmonizing the physical world and the Bible can be appreciated, there are some misconceptions about proper concordance between the two. Summary: The author begins with an explanation of what the Reformed Tradition is, and why it is important. She continues by explaining his main point, that while the idea of concordance physical world and the Bible is a good one, there are problems specifically with how the two are in concordance with regards to the natural world, and with regards to God. She explores these ideas by examining the words of many different Reformists over the years, back to John Calvin of the 16th century. Using the words of John Calvin, she examines the idea that the revelation of God, as represented through both the natural world, and the Bible, must be viewed from the perspective of the Bible. She concludes...

Phenomenology

...Phenomenology: A research tool in nursing practice Phenomenology: A research tool in nursing practice Description of the problem Nursing as a discipline and branch of science has grown tremendously over the years. The use of research, scientific inquires, evidence-based practice, and scientific validations have contributed immensely to this growth. Several disciplines such as Psychology, Sociology, Arts, and Philosophy have played major factors in the growth of nursing as a science. Science as a discipline is never static and continues its growth through the use of quantitative and qualitative research inquires. Phenomenology is a branch of philosophy that aims to utilize methodology in nursing research (Tuohy, Cooney, Dowling, Murphy, & Sixsmith, 2013). This paper will focus on the role of phenomenology as a research tool in nursing practice and the similarities between phenomenology and the views of logical positivists. Background and significance Edmond Husserl is recognized as the pioneer of Phenomenology, having introduced this movement at the beginning of the 20th century (Tuohy et al., 2013). Phenomenology as a branch of philosophy focuses on the importance of exploring the realities of life and living, it is a method of recounting occurrences as it appears to the person experiencing the occurrence (Tuohy et al., 2013). Phenomenology is described as a movement because unlike other philosophical views; it...
