Crowdsourcing civility: A natural experiment examining the effects of distributed moderation in online forums

Participation in discussions about the public interest can be enhanced by technology, but can also create an environment in which participants are overwhelmed by the quantity, quality, and diversity of information and arguments. Political participation is at a greater disadvantage than non-political activities in that participants from different parties already start out with established differences, which requires them to reach some form of common ground before progress can be made. Those seeking authentic deliberation are discouraged to participate when confronted with uncivil and inflammatory rhetoric. These issues are often exacerbated in online discussions, where lack of identity cues and low barriers to entry can lead to heightened incivility between participants, often labeled as “flaming” and “trolling”. This paper explores the extent to which moderator systems, tools online discussion forums use to manage contributions, can reduce information overload and encourage civil conversations in virtual discussion spaces. Using the popular website Slashdot as an example of sound moderation in a public discourse setting, we found that users move toward consensus about which and how comments deserve to be moderated. Using these findings, we explore how transferable these systems are for participation in public matters specifically to the unique attributes of political discussion. Slashdot's political forum provides a comparison group that allowed us to find quantitative and qualitative differences in political posting, comments, and moderation. Our results show that large scale, civil participation is possible with a distributed moderation system that enables regularly lively debates to be conducted positively because the system provides tools for people to enforce norms of civility.     

Identification of Core Competencies for an Undergraduate Food Safety Curriculum Using a Modified Delphi Approach

Identification of core competencies for undergraduates in food safety is critical to assure courses and curricula are appropriate in maintaining a well‐qualified food safety workforce. The purpose of this study was to identify and refine core competencies relevant to postsecondary food safety education using a modified Delphi method. Twenty‐nine experts representing food safety professionals in academia, government, and industry were given 2 rounds of questionnaires that specified initial food safety competencies, core domains, and subdomains. Competencies were defined as a set of skills, knowledge, and abilities that correlate to success of a trainee. The framework for which competencies were classified consisted of (1) core domains, defined as broad food safety subjects; and (2) subdomains, or more specific food safety subjects. The expert panel used a 5‐point Likert scale with an acceptance criterion, or consensus, of 75%, with a rating of “4” or greater. After 2 rounds of questionnaires and revisions from the expert panel, 5 core domains were established: (1) Food Production, Manufacturing, Retail, and Consumer; (2) Foodborne Hazards; (3) Public Health; (4) Legislation and Policy; and (5) Communication and Education. Specific responses from the experts highlighted areas in which further curriculum revision would be beneficial. This study provides a framework for the development of a vetted, standardized undergraduate food safety curriculum. The Delphi method, with its inclusion of professionals representing various sectors of food safety, provided relevant perspectives for curriculum design, and also allowed participants the opportunity to contribute to the education of future food safety professionals.     

Emotional Autonomy Redux: Revisiting Ryan and Lynch

Ryan and Lynch have suggested that emotional autonomy in adolescence, at least as indexed by Steinberg and Silverberg's Emotional Autonomy Scale, is associated with poor family functioning and might therefore be better conceptualized as detachment. In the present study, we contrast adjustment scores among adolescents who differ in both emotional autonomy and perceptions of support in their relationship with their parents. Several thousand adolescents aged 14 through 18 completed Steinberg and Silverberg's emotional autonomy measure, a measure designed to assess the provision of support in the parent-adolescent relationship, and a number of standardized measures of adjustment. Adolescents high in emotional autonomy but low in relationship support show problematic adjustment profiles, consistent with Ryan and Lynch's interpretation of the measure as an index of detachment. Although adolescents high in both emotional autonomy and relationship support report more internal distress and behavior problems than some adolescents, they score higher on measures of psychosocial development and academic competence than their peers. Emotional autonomy in the context of a supportive adolescent-parent relationship may carry some developmental advantages as well as some deleterious consequences suggested by Ryan and Lynch.     

Academics Hard at Work: the place of teaching and professional development related to teaching

Abstract

Recent studies of academic work have identified increasing pressures on universities and academics throughout the world. These pressures relate to such factors as diminishing resources available to the higher education sector, widening diversity of the student clientele, moves for increased accountability and tensions between the research and teaching goals of academic work. Among the pressures being placed on the teaching component of academic work are the need for increased accountability of teaching performance and the need to update professional competence related to teaching. This paper reports a study of a selected group of academics — relatively junior staff who have participated in significant professional development activities related to their teaching. The data provided by the interviews with these academics allow a glimpse at their academic lives and how they fit teaching and professional development related to teaching into their working lives. The study highlights how these academics structure their work around their teaching commitments and how, although they make time available for professional development related to their teaching, this is done in response to the activities offered rather than as a proactive component of their career planning.     

Developing,Evaluating and Demonstrating the Use of a Conceptual Survey in Mechanical Waves

An understanding of mechanical waves is a pre‐requisite for the study of many topics in advanced physics, and indeed in many other disciplines. There have been many research studies in mechanical waves, all of which have revealed that students have trouble with the basic concepts. Therefore, in order for teachers to prepare appropriate instruction for their classes, it is useful to diagnose their students' conceptions—if possible before they enter class. It is for this purpose that many diagnostic instruments have been developed, often in the form of multiple‐choice tests. In this study, we have used the open‐ended Wave Diagnostic Test to develop a multiple‐choice conceptual survey in an evolutionary manner. The two‐year development procedure included open‐ended surveys and interviews involving 299 Thai students and 88 Australian students. The final version, called the Mechanical Waves Conceptual Survey, has been administered to 632 Australian students from high school to second‐year university and 270 Thai high school students. Standard statistical analyses show that the survey is reliable and valid. Further validity checks, including consultation with experts, were also carried out. The survey has four subtopics—propagation, superposition, reflection, and standing waves—and the teachers can choose the subtopics relevant for their students. In this paper we also demonstrate the use of a typical survey question to test students' conceptual understanding and identify common alternative conceptions.
