What happens when brands tell the truth? Exploring the effects of transparency signaling on corporate reputation for agribusiness

This study focused on Corporate Social Responsibility (CSR) within agribusiness – an industry confronted with particularly high expectations from its societal environment. This study examined the effects of transparency signaling and its interaction with the nature of CSR on publics’ evaluation of an agribusiness company with regards to perceived integrity, perceived competence, and company reputation. Our findings showed that high transparency signaling led to higher perceived integrity, but there were no significant effects on perceived competence and company reputation. Moreover, the effects of transparency signaling were moderated by the nature of CSR on company reputation. The study also revealed that perceived integrity influenced the relationship between transparency and company reputation, while perceived competence was not influenced by transparency signaling. Researchers discuss the implications of these findings for communication professionals sharing CSR information, especially for high involvement industries like food and agriculture.     

The Car Accident: An Exercise in Persuasive Writing

Objective: To teach students to argue persuasively using evidence to support their assertions; to learn clear logical writing that focuses on the audience and uses strategies for persuasion; to incorporate theory into a very practical scenario and understand the importance of purpose, audience, and situation

Courses: Business communication, persuasion, and organizational communication classes     

The influence of group size on children's competitive behavior

The present research was designed to test the hypothesis that children would compete more in tetrads than in dyads. Twenty-two pairs of male and 14 pairs of female target children (N = 72) played a competitive game in both tetrads and dyads. Consistent with the hypothesis, male target children competed more in tetrads than in dyads. This hypothesis was not supported for females, however. Analyses of the dynamics of tetrads and dyads further demonstrated that based on a global measure of smiling, the emotional atmosphere was less positive in tetrads than in dyads. The causes and consequences of interaction in different sized social groups are discussed.     

The case for a new tenure policy

Caught between serious concern about their tenure levels and the paucity of feasible policy options, many institutions have reacted by making all new appointments outside the tenure system. The secondary purpose of this paper is to show that this conservative and seemingly safe solution is not without its faults and has, in fact, a very wide spectrum of faults. The primary purpose is to show how a modification of this tenure-system-freeze policy can eliminate most of the deficiencies of the policy and yet sacrifice only a small increment of the advantage. This modification is arrived at using an analytical model of the tenure system, and the theoretical results are demonstrated in the concrete form of a numerical example.     

Unmasking the unasked: correcting the record about assessor masking as an explanation for effect size differences

Ainsworth et al.’s paper “Sources of Bias in Outcome Assessment in Randomised Controlled Trials: A Case Study” examines alternative accounts for a large difference in effect size between 2 outcomes in the same intervention evaluation. It argues that the probable explanation relates to masking: Only one outcome measure was administered by those aware of participants’ treatment assignment. This paper shows this conclusion is not substantiated by the evidence: The original paper fails to exclude alternative explanations, and what it takes as positive evidence for the preferred explanation is actually negative. While accepting the importance of masking in randomised controlled trials, this paper concludes that the original question was based on a misconception about effect sizes: Seen correctly as a measure of whole study design, the question of effect size difference between different outcome measures does not need asking.     

Three concepts or one? Students’ understanding of basic limit concepts

In many mathematics curricula, the notion of limit is introduced three times: the limit of a sequence, the limit of a function at a point and the limit of a function at infinity. Despite the use of very similar symbols, few connections between these notions are made explicitly and few papers in the large literature on student understanding of limit connect them. This paper examines the nature of connections made by students exposed to this fragmented curriculum. The study adopted a phenomenographic approach and used card sorting and comparison tasks to expose students to symbols representing these different types of limit. The findings suggest that, while some students treat limit cases as separate, some can draw connections, but often do so in ways which are at odds with the formal mathematics. In particular, while there are occasional, implicit uses of neighbourhood notions, no student in the study appeared to possess a unifying organisational framework for all three basic uses of limit.     

College student epistemological perspectives across knowledge domains: A proposed grounded theory

Scholars have studied epistemologicaldevelopment – or how one understands knowledgeand knowing – of college students for manyyears. Research in this domain has includedbenchmarking studies of epistemologicaldevelopment, examinations of how curricularinnovations impact epistemology, and somestudies of differences in epistemologicaldevelopment based on disciplinary areas. Thelatter group of studies has generally focusedon differences in epistemological beliefs forstudents who are studying in two differentdomains (e.g., nursing students versus physicsstudents). In this study, we qualitativelyinvestigate whether the epistemologicalperspectives of 60 science/engineering collegestudents differs across the disciplinary areasof the sciences and the humanities. Our resultsindicate that such differences do exist andinclude a proposed grounded theory thatdescribes how students' epistemologies may varyacross knowledge domains.     

A review of research into stakeholder perspectives on inclusion of students with autism in mainstream schools

Increasing numbers of students with autism are being educated in mainstream schools. However, outcomes for students with autism are poor when compared to typical students and students with other developmental disabilities. In order to better understand facilitators and barriers to success at school for students with autism, research into the attitudes of key stakeholders, educators, parents, people with autism, to inclusion in mainstream schools for students with autism, was reviewed. Key themes emerging included attitudes to inclusion, the characteristics of autism and social communication in particular and interaction with the school environment, and consequent student problem behaviour. Level of knowledge and understanding of school staff emerged as the primary issue with all stakeholders identifying the need for more training. Other support needs identified included the need for structural support, resources and funding. Parents, in particular, identified the need for a collaborative approach to the education process. The findings highlight the need to translate theory into practice to increase capacity in schools to provide effective educational programmes for students with autism.
