Chaos theory, informational needs, and natural disasters

This study applies chaos theory to a system-wide analysis of crisis communication in a natural disaster. Specifically, we analyze crisis communication during the 1997 Red River Valley flood in Minnesota and North Dakota. This flood, among the worst in modern American history, consumed entire metropolitan areas, displacing thousands of people. The conditions and decisions leading to the disaster, and the subsequent reactions are retraced. Communication related to river crest predictions (fractals), the shock at the magnitude of the crisis (cosmology episode), novel forms of reorganizing (self-organization), and agencies that aided in establishing a renewed order (strange attractors) are evaluated. Ultimately, we argue that preexisting sensemaking structures favoring rationalized, traditional views of a complex system led officials to make inappropriately unequivocal predictions and ultimately diminished the effectiveness of the region's crisis communication and planning.     

Social working memory: Memory for another rat's spatial choices can increase or decrease choice tendencies

In two experiments using a radial-arm maze, pairs of rats made choices among eight maze locations, each containing a large quantity of one of two food types. The choices made by 1 rat affected the choices made by the other rat. Under most conditions, visits by 1 rat increased the tendency of the other rat to subsequently choose that maze location. However, the effect depended on the quality of the food available in a particular location. When it was possible for the rats to observe each other on the maze arms and a rat had experienced that a location contained the less preferred food type, a previous visit to that location by the foraging partner decreased the tendency to visit that location. These effects are attributed to working memory for the spatial choices of another rat, and they indicate that memory produced by a rat’s own visit to a maze location is integrated with memory for the behavior of another rat to determine spatial choice     

Nothing about us without us! Youth-led solutions to improve high school completion rates

This Youth Participatory Action Research (YPAR) study represents a collaboration with six students from alternative education to inquire about the experiences of vulnerable youth – students in alternative education and youth who have dropped out of school. Utilizing the Enhanced Critical Incident Technique, youth researchers asked their peers what helped and hindered their retention and success in mainstream and alternative education. Youth researchers engaged in authentic participation and took part in the iterative phases of YPAR – critical reflection and social action. Their involvement empowered them to advocate for their peers by disseminating the results and recommendations to key stakeholders within the community. Youth researchers conducted semi-structured interviews with 18 participants. Overall, the findings show that relationships with staff and peers, flexibility, psychosocial and academic supports, and personal circumstances are vital in helping vulnerable students succeed in school. Engagement in YPAR provided insight into working with vulnerable youth in a manner that promotes agency and social change within educational institutions.     

A Complex Case: Using the case study method to explore uncertainty and ambiguity in undergraduate business education

The case method is a definitive and foundational technology in business education. It was first developed as a vocational training tool equipping students for future employment. In this conception, the organisation was seen as a machine, and managers as the engineers who would maintain it through planned interventions. The case method allowed aspiring managers to practise intervention skills in a safe environment. Since the origins of the case method in US business schools before the First World War, conceptions of organisations have moved on. They are no longer seen as machine-like, but as complex, ambiguous, and protean. The 'wicked' problems that potential managers will face in an uncertain world require the development of critical thinking and sensemaking abilities. While the traditional approach to the case continues, its use as a vehicle to explore and manage complexity and ambiguity is emerging, although this is facing resistance from some students and staff.     

Can Examinees Use a Review Option to Obtain Positively Biased Ability Estimates on a Computerized Adaptive Test?

Part of the controversy about allowing examinees to review and change answers to previous items on computerized adaptive tests (CATs) centers on a strategy for obtaining positively biased ability estimates attributed to Wainer (1993) in which examinees intentionally answer items incorrectly before review and to the best of their abilities upon review. Our results, based on both simulated and live testing data, showed that there were instances in which the Wainer strategy yielded inflated ability estimates as well as instances in which it yielded deflated ability estimates. The success of the strategy in inflating ability estimates depended on the ability estimation method used (maximum likelihood versus Bayesian), the examinee's true ability level, the standard error of the ability estimate, the examinee's ability to implement the strategy, and the type of decision made from the ability estimate. We discuss approaches to dealing with the Wainer strategy in operational CAT settings.     

Effects of participation in a martial arts–based antibullying program in elementary schools

This study evaluated the Gentle Warrior Program, a traditional martial arts–based intervention to reduce aggression in children, as it was implemented in three elementary schools. The sample consisted of 254 children in grades 3, 4, and 5 who participated in the Gentle Warrior Program as part of a larger school violence intervention. Results indicated that boys who participated in more Gentle Warrior sessions reported a lower frequency of aggression and greater frequency of helpful bystanding (i.e., helpful behavior toward victims of bullying) over time, relative to boys with less frequent participation. The effect of participation on aggression was partially mediated by empathy. The effect of participation on helpful bystanding was fully mediated by changes in student empathy. No significant results were found for girls. Results of the study provide preliminary support for the use of martial arts–based interventions to address bullying in schools for boys, by teaching empathy, self‐control, and peaceful strategies to resolve conflicts. © 2008 Wiley Periodicals, Inc.     

Mathematical thinking in second-grade children with different forms of LD

Based on their performance on a standardized achievement test, second-grade children (N = 49) were classified as having mathematics difficulties with normal reading achievement (MD only), both mathematics and reading difficulties (MD/RD), reading difficulties with normal mathematics achievement (RD only) and normal mathematics and reading achievement (NA). Each child was given a series of tasks so that we might assess their thinking across four areas of mathematics: number facts, story problems, place value, and written calculation. Children with MD/RD performed significantly worse than NA children in most areas of mathematical thinking, whereas children with MD only performed worse than NA children only on complex story problems. The MD-only group outperformed the MD/RD group on story problems and written calculation. No significant differences were found between the RD-only and NA groups on any of the tasks. The results suggested that among children with mathematics difficulties, the MD/RD subgroup is distinct from the MD-only subgroup, with the former being characterized by pervasive deficiencies in mathematical thinking and the latter by more specific deficits in problem solving.     

Using kindergarten number sense to predict calculation fluency in second grade

Children's number sense in kindergarten was used to predict their calculation fluency in second grade (N = 198). Using block entry regression, usual predictors of age, reading, memory, and verbal and spatial cognition were entered in the first block and number sense measures were added in the second block. Number sense measures contributed a significant amount of variance over and above the more general predictors (26%-42%). Uniquely predictive subareas were active memory for numbers, number knowledge, and number combinations, with number combinations standing out as the strongest single predictor. Number sense screening in kindergarten, using "at-risk" versus "not-at-risk" criteria, successfully ruled out 84% of the children who did not go on to have calculation fluency difficulties and positively identified 52% of the children who later showed fluency difficulties. The relation of early number skills to later calculation fluency has important implications for math screening and intervention.     

Press Credentials and Hybrid Boundary Zones: The Case of WorldNetDaily and the Standing Committee of Correspondents

ABSTRACT

Press credentialing practices are a vital, yet understudied site of scholarly research on journalistic norms and practices. Press credentialing not only structures internal professional hierarchies, but they also signify the boundaries of the journalistic field itself. This paper explores the legal and theoretical implications of press credentialing to cover the United States Congress, drawing on the concepts of boundary work and journalistic authority to demonstrate the material impact of the space between fields on professional legitimation in journalism. Using WorldNetDaily (WND) as a case study, I argue that the Standing Committee of Correspondents (SCC) occupies a hybrid boundary zone between the journalistic and political fields, generating a unique tension in First Amendment jurisprudence that places journalists in a paradoxical role as both the professional embodiments of free speech and its constitutional steward. The resulting jurisdictional conflict between the SCC and WND extends the relational model of journalistic authority by articulating how journalist-state relations can fundamentally augment the process of legitimation at its fuzzy boundaries. The relevance and implications for press credentialing practices in the digital age are discussed.     

Religious Pluralistic Language in a Computer-Mediated Context: Effects of Intergroup Salience and Religious Orientation

This study investigated the degree to which religious pluralistic language varies as a function of the intergroup salience of a context and religious orientation. Based on a 2 (Religious Salience of Context) × 3 (Religious Salience of Topic) experimental design, participants (N = 239) were instructed to compose an e-mail to an interactional partner based on the randomly assigned condition. Messages were coded for religious pluralistic language, and participants completed measures of religious orientation and evaluations of the conversational partner. Modest effects were found for both intergroup salience of the context and topic as well as religious orientation.
