Sorting out the ethics of propaganda

“Social movement”; is a set of meanings and not an objective phenomenon. We therefore require explanations of “movement”; in rhetoric, not explanations of persuasion in allegedly discrete and objective situations.     

The Need to Emphasize Epistemology in Teaching and Research

The views on epistemology by philosophers of science are developed through an historical lens. Enabling students to develop a scientific mindset is complicated by student’s views on the Nature of Science. Students need to appreciate the history of science and to contrast different frameworks. In order to do this, students have to be able to follow presentations in class and read their textbooks. Although individual words are understandable, the sentences appear to take the form of an unknown language. The solution utilized in this paper is to get students to approach their reading of their textbooks in the manner of the hermeneutical circle through an activity called Reflective Writing.     

The garbage gospel: Using the theory of planned behavior to explain the role of religious institutions in affecting pro-environmental behavior among ethnic minorities

This study used Azjen's Theory of Planned Behavior to examine how pro-recycling and pro-environmental messaging delivered by religious leaders affects stated recycling behavior among ethnic minorities. Using data collected from 12 religious institutions in three Ontario, Canada, communities, a promotion and education program was developed to: (1) increase awareness about existing waste management programs in the region; (2) describe what materials should be recycled; (3) highlight the importance of recycling (to the individual, to the community, and to the environment; and (4) make a direct appeal asking households to participate in their region's recycling programs. Post implementation of the P&E campaign, respondents indicated a statistically significant increase in positive attitudes toward recycling, moral norms, levels of perceived behavioral control, and awareness of recycling consequences. Perceived behavioral control, situational factors, attitudes, and moral norms were found to be the most significant predictors of recycling intention. Community leaders were demonstrably more successful in affecting positive change in stated recycling behavior among minorities relative to previous municipal promotion and education efforts.     

Cinderella in Serum Protein Electrophoresis

Paraproteinemia is characterised by clonal proliferation of plasma cells. A common laboratory finding in paraproteinemia being a monoclonal peak in serum protein electrophoresis (M band). But there are factors which produce a peak similar to M spike in serum protein electrophoresis and these factors are known as pseudoparaproteins. This case report discusses a rare cause of pseudo M spike in a known case of autoimmune hemolytic anaemia due to administration of drug-Rituximab, a monoclonal antibody by itself.     

On the Concept of Force: A Comment on Lopes Coelho

This article presents a supplement to Coelho’s excellent article concerning the definition of force by first defining mass and then momentum. Replacing force with the concept of a field is also briefly noted.     

Can an Analysis of the Contrast Between pre-Galilean and Newtonian Theoretical Frameworks Help Students Develop a Scientific Mindset

This study examines a course in which students use two writing activitiesand collaborative group activities to examine the conceptual structure ofthe calculus-based introductory Physics course. Students are presented withtwo alternative frameworks; pre-Galilean Physics and Newtonian Physics. Theidea of the course design is that students would at first view the frameworksalmost in a theatrical sense as a view of a drama involving a conflict of actors;Aristotle, Galileo, Newton and others occurring a long time ago. As participantspassing through a series of interventions, the students become aware that theframeworks relate concepts from different parts of the course and learn to evaluatethe two alternative frameworks. They develop a scientific mindset changing theiroutlook on the course material from the viewpoint that it consists of a tool kit ofassorted practices, classified according to problem type, to the viewpoint that itcomprises a connected structure of concepts.     

Risk of mother-reported child abuse in the first 3 years of life

OBJECTIVE: The purpose of this research was to investigate, within an at-risk population, parent and child characteristics associated with a mother's self-reports of severe physical assault and assault on the self-esteem of the child in the first 3 years of life. DESIGN: The study population consisted of a community-based sample of mothers of newborns identified as at-risk for child maltreatment (n=595). Families were assessed annually from the child's birth through age 3 using instruments with established psychometric properties. Independent variables investigated included: family socio-demographics, parity, mother's social support, maternal depression, maternal problem drug or alcohol use, partner violence, child's age, child's sex, low birth weight/small for gestational age (SGA), and mother's perception of child's demand level. Associations with maltreatment were examined using multivariable methods for longitudinal data. RESULTS: Child severe physical assault was significantly associated with parent characteristics (maternal depression and partner violence); and child characteristics (SGA). Assault to the child's self-esteem was significantly associated with maternal depression, maternal illicit drug use, partner violence and mother's perception of child's demand level. Controlling for family sociodemographic characteristics did not change the associations. Likewise, while mother's perception of child demand level had an independent association with self-esteem assault, the associations described above persisted while demand level was held constant. In this high-risk sample, abuse was not associated with mother's age, education, race, parity, or household income level. CONCLUSIONS: While characteristics such as SGA can serve as markers for increased abuse risk, they are not amenable to intervention after the child is born. However, certain other risk factors, such as maternal depression and domestic violence are malleable and should be targeted for intervention with the goal of preventing child maltreatment.
