Power in Bayesian Mediation Analysis for Small Sample Research

Bayesian methods have the potential for increasing power in mediation analysis (Koopman, Howe, Hollenbeck, & Sin, 2015; Yuan & MacKinnon, 2009). This article compares the power of Bayesian credibility intervals for the mediated effect to the power of normal theory, distribution of the product, percentile, and bias-corrected bootstrap confidence intervals at N ≤ 200. Bayesian methods with diffuse priors have power comparable to the distribution of the product and bootstrap methods, and Bayesian methods with informative priors had the most power. Varying degrees of precision of prior distributions were also examined. Increased precision led to greater power only when N ≥ 100 and the effects were small, N < 60 and the effects were large, and N < 200 and the effects were medium. An empirical example from psychology illustrated a Bayesian analysis of the single mediator model from prior selection to interpreting results.     

Retirement lifestyle conceptualization and well-being in recent retirees

ABSTRACT

The retirement literature contains four distinct conceptualizations of retirement lifestyle. Retirement can be seen as an opportunity to make a new start, the continuation of a pre-retirement lifestyle, an unwelcome imposed disruption, and a transition to old age. This research examines the conceptualizations of retirement lifestyle and how they relate to retirement adjustment and well-being in recent retirees (N = 173). A factor analysis confirmed the existence of four factors identifying four retirement conceptualizations. Although previous studies have presented retirement conceptualizations as mutually incompatible, significant relationships were found between them in this research, indicating that recent retirees can synchronously conceptualize seemingly distinct lifestyles. The cluster analysis identified three types of retirees in the sample. These types were labeled to reflect the prevailing retirement lifestyle concepts. The first type of retiree (N = 90) is “New beginning and continuation,” the second (N = 44) is “Imposed disruption without hope,” and the third is (N = 39) “Accepted disruption and ending.” The analysis of variance revealed the three types differ significantly in the level of satisfaction in retirement, subjective happiness, and life meaningfulness – with the highest level being found in the first retiree type and the lowest level in the second retiree type. The findings suggest that conceptualizations of retirement lifestyle change over time and affect psychological well-being in the recent retiree cohort. The theoretical and practical implications of the results are outlined.     

Recommendations for effective university study based on students’ point of view

This research examined what university students recommend for effective university study and whether their recommendations differ by gender, faculty or study programme degree. The research was based on 985 questionnaires. The following words were most commonly used in advice for freshmen: Go, Lectures, Learn, Continuously, Be, Prepare, Information, Have, Do, Materials. The fundamental advice seems to be: to go to lectures, to have needed materials and information and to learn and prepare continuously. Some stated recommendations react to the development of information and communication technologies and the massive usage of the Internet (such as obtaining a laptop and a cell phone or setting up a Facebook profile). Quite a lot of advice was connected with health, such as to sleep enough, to eat regularly, to not smoke, to relax and to restrict alcohol consumption. The recommendations gained in this survey were categorised by thematic similarities to characteristics, knowledge, skills, behaviour and background. The findings highlight the fact that given recommendations for effective study differ by the respondent’s gender and faculty. Women concentrated more on recommendations on how to behave and men mentioned more often what personality characteristics are important for effective university study. Students of the Faculty of Multimedia Communications highlighted the necessity of creativity and practical experience more often than others.     

Plants have a chance: outdoor educational programmes alter students' knowledge and attitudes towards plants

Outdoor educational programmes are generally believed to be a suitable alternative to conventional biology settings that improve participants' environmental attitudes and knowledge. Here we examine whether outdoor educational programmes focused solely on practical work with plants influence participants' knowledge of and attitudes towards plants. It was found that mean scores of participants' attitudes towards and knowledge of plants significantly increased after the outdoor programme. These effects remained significant even after three months' post‐testing. No similar patterns were found in the control group. Interestingly, the proportion of participants who liked biology as a school subject also significantly increased after the outdoor programme in the experimental group. Females showed better knowledge of plants than males, but attitudes towards plants were similar between genders. Having a garden at home was not associated with better knowledge or attitudes towards plants. Our results reveal that outdoor programmes significantly relieve ‘plant blindness’ and make biology more attractive to pupils.     

Good and evil at school: Bullying and moral evaluation in early adolescence

We investigated how adolescents (sixth-graders, N = 357) morally evaluated hypothetical bullying and defending protagonists and whether these evaluations related to behavior in bullying as nominated by peers. Exploratory factor analysis (EFA) resulted in four factors for the evaluation of the hypothetical bullies: Evil soul, Contempt, Cowardice, and Deviance, and five factors for the evaluation of the hypothetical defender: General admiration, Courage, Cool, Empathic care, and Fair justice. Corresponding scales were constructed. The findings showed that bullying positively correlated with evaluating the hypothetical bullies using Cowardice while victimization positively correlated with evaluating the hypothetical defender in terms of General admiration, Empathic care, and Fair justice. MANOVA for each of the two sets of the evaluative scales indicated that behavioral status (bully, victim, defender, or uninvolved) had a significant effect on the moral evaluation of hypothetical bullies, and no significant effect on the moral evaluation of the hypothetical defender.     

That’s Not For Our Kids: The strange death of philosophy and ethics in a low socioeconomic secondary school

Abstract

This article reflects on the successes and failures of a new Philosophy and Ethics course in a low socioeconomic context in Perth, Western Australia, with the eventual demise of the subject in the school at the end of 2010. We frame this reflection within Deleuzian notions of geophilosophy to advocate for a Philosophy and Ethics that is informed by nomadic thought, as this offers a critical freedom for students to transform themselves and their society and suggests practical ways both of overcoming the prejudices which led to its demise and of student reluctance to engage in open discussion in class. We consider the demise of the course a ‘missed opportunity’ because it had so much potential to be transformative of student subjectivities in schools.

Experiential and outdoor education: the participant experience shared through mind maps

This paper describes an analysis of mind maps capturing the experiences of the participants in an experiential and outdoor education course. The method of mind mapping is usually limited to a quantitative scoring analysis and comparative content analysis of concepts. As a consequence, the visual elements of the information are usually ignored, but to analyze the holistic information, it is necessary to analyze its visual elements. This intention underlines this study of five chosen pairs of mind maps made by participants in the outdoor course comparing their impressions at the beginning and end of the course. A qualitative review of the visual and symbolic levels of information found a significant impetus occurring in the participants’ view of their life journey and the possibility of changes due to the course experience. There is a visible tendency toward changes between first and second maps, from vague fears to acceptance of one's self, from polarity to holistically perceived reality, from vague concepts to colorful visual symbolism, from focus on the past to open acceptance of the future, from personality to community, and from the physical dimension of the experience to the spiritual or holistic level of the meaning of the experience.     

Dearth of early education experience: a significant barrier to educational and social inclusion in the Western Balkans

The article summarises the socio-political, cultural, economic and educational background to the Western Balkans region and outlines the wider qualitative research study that provided the data on early and pre-school educational opportunities in the seven countries involved; Albania, Bosnia and Herzegovina, Croatia, Kosovo (under United Nations Security Council Resolution 1244), the Former Yugoslav Republic of Macedonia, Montenegro and Serbia. The authors examine international research and literature on early education that identifies it as an important means of enabling subsequent educational and social inclusion and attainment. They proceed to discuss and illustrate from the research data five inter-linked factors showing that provision of early education in the Western Balkans is inadequate and exclusive and that children who are already at greatest socio-economic and cultural disadvantage and at potential risk in elementary and secondary education are least likely to participate in, or benefit from, it. Some recent more encouraging developments are noted but the article concludes that substantially more investment and positive actions are needed in raising awareness of the importance of early education and in developing policies and provision for it that will benefit children currently at greatest disadvantage.     

From Pride to Smugness and the Nationalism Between: Olympic Media Consumption Effects on Nationalism Across the Globe

To measure relationships between Olympic media viewing and nation-based attitudes, 6 nations (Australia, Bulgaria, China, the Netherlands, Slovenia, and the United States) were surveyed in the 5 days immediately after the 2012 London Olympics. A total of 1,025 respondents answered questions pertaining to four measures of nationalism: patriotism, nationalism, internationalism, and smugness. The amount of Olympic viewing resulted in significantly higher scores for patriotism, nationalism, and smugness, but not internationalism. In addition, differences by nation are reported, revealing considerable differences in nationalism measures among the 6 nations studied; for instance, the United States was the lowest of the 6 nations regarding internationalism yet highest of the 6 nations regarding smugness. Conclusions related to theory and the role of Olympic media content are offered.
