Students with LD at Postsecondary: Supporting Success and the Role of Student Characteristics and Integration

Students with learning disabilities (LD) are attending postsecondary education more than ever, but are also less likely to complete their education compared to non-LD peers. Using the Inputs–Environment–Outcomes model of Astin, we examined students with LD and non-LD peers during their first year of postsecondary studies. Using structural equation modeling, we found that for all students, perceived academic ability had a positive direct effect on outcomes, whereas drive to achieve had only an indirect effect. Academic integration was important for grade point average and satisfaction. Social integration was important for the acquisition of knowledge and skills and satisfaction, and these connections were stronger for students with LD. Our discussion highlights potential supports for students with LD.     

How does the World Trade Organization know? The mobilization and staging of scientific expertise in the GMO trade dispute

The World Trade Organization (WTO) dispute settlement procedure is a key arena for establishing global legal norms for what counts as relevant knowledge. As a high-profile case, the WTO trade dispute on GMOs mobilized scientific expertise in somewhat novel ways. Early on, the Panel put the dispute under the Sanitary and Phytosanitary (SPS) Agreement through a new legal ontology; it classified transgenes as potential pests and limited all environmental issues to the 'plant and animal health' category. The selection of scientific experts sought a multi-party consensus through a fast adversarial process, reflecting a specific legal epistemology. For the SPS framing, focusing on the defendant's regulatory procedures, the Panel staged scientific expertise in specific ways that set up how experts were questioned, the answers they would give, their specific role in the legal arena, and the way their statements would complement the Panel's findings. In these ways, the dispute settlement procedure co-produced legal and scientific expertise within the Panel's SPS framework. Moreover, the Panel operated a procedural turn in WTO jurisprudence by representing its findings as a purely legal-administrative judgement on whether the EC's regulatory procedures violated the SPS Agreement, while keeping implicit its own judgements on substantive risk issues. As this case illustrates, the WTO settlement procedure mobilizes scientific expertise for sophisticated, multiple aims: it recruits a source of credibility from the scientific arena, thus reinforcing the standard narrative of 'science-based trade discipline', while also constructing new scientific expertise for the main task--namely, challenging trade restrictions for being unduly cautious.     

Did the Gamemakers Fix the Lottery in the Hunger Games?

The Hunger Games is an annual event in the fictional country of Panem. Each year, 24 children (tributes) are chosen by lottery from 12 districts to fight to the death in the arena for the entertainment of the Capitol citizens. Using statistical analysis and computer simulations, we will explore the possibility that the Gamemakers, those in charge of planning the Hunger Games, fixed the lottery. Using the fictitious data from Suzanne Collins' book the Hunger Games, we show how students can learn how to perform a permutation goodness of fit test.     

Young children's encoding of images based on motor and verbal modes of mediation

Twenty-four kindergarten subjects were given practice producing a geometric production when given the three dimensional object. Six children were told how to draw the projections, six children drew the projections, six children drew the projections and were told how to draw the projections, and six children were told to remember the drawings. Using a two-way analysis of variance, the main effect of motor activity (drawing the projections) was significant (p < .05). It was concluded that children's learning activities should be motor based, rather than verbal.     

Impulsive cognitive tempo in severe and mild learning disabled children

The purpose of the study was to compare the performance of severe and mild learning disabled children to normal children on a problem-solving task. The three types of children were assessed on the Matching Familiar Figures task, which provides a measure of impulsivity during problem-solving tasks. Results indicated that on the MFF, LD children, as a group, were more impulsive than normal children, and severe LD were more impulsive than mild LD children. Impulsivity scores were correlated with reading achievement, indicating a relationship between problem-solving strategy and academic performance. Educational implications are discussed regarding the usefulness of the reflection-impulsivity dimension in the area of learning disabilities and the applicability of the MFF as a diagnostic and evaluative measure.     

An experience sampling study of organizational stress processes and future playing time in professional sport

ABSTRACT

This study examined the relationships between daily cognitive appraisals of organizational events, affective responses, and coping. In addition, a 5-year longitudinal relationship between coping and performance outcomes at the senior professional level was assessed. Using an experience sampling method, professional academy rugby union players (N = 39, M_age = 17.23 years, SD = 0.87) completed daily diary measures of appraisals, affective responses, and coping over 5 weeks of training. Hierarchical linear modeling revealed that daily cognitive appraisals were related to daily affective responses and coping functions enacted by behaviours, after accounting for a series of within (e.g., time, day, week) and between-person (e.g., personality, key decision-makers) differences. Zero-inflated negative binomial regression revealed that coping related to eliciting support was associated with minutes played at the senior professional level five years later. This study extends theoretical knowledge of the within- and between-person relationships that explain organizational stress experiences. The findings suggest that some coping functions enacted by behaviours may be early indicators of future performance outcomes in professional sport.     

Impact of family abuse on running away, deviance, and street victimization among homeless rural and urban youth

PROBLEM: Various demographic and familial risk factors have been linked to runaway behavior. To date, there has not been a systematic investigation of the impact of size of community on runaway behavior. This study will compare runaways from smaller cities and rural areas to their urban counterparts. METHODS: A convenience sample of 602 adolescents was interviewed between 1995 and August of 1996 in Missouri, Iowa, Nebraska, and Kansas, USA. Multiple regression was used to examine the association between gender, neglect, sexual abuse, physical abuse, geographic and family structure change, and community size of first runaway to predict age at first runaway, deviant subsistence strategies, and street victimization. RESULTS: Findings indicate that adolescents exposed to neglect (beta=-.20) and sexual abuse (beta=-.16) ran away sooner and were more likely to be victimized on the street. Rural adolescents who experienced higher levels of physical abuse relied more heavily on deviant subsistence strategies (beta=.15) and remained in abusive homes longer (beta=.15) than their similarly situated urban counterparts. CONCLUSIONS: Rural youth who have been subjected to elevated levels of familial abuse are at greater risk of deviant subsistence strategies, which increase the likelihood of street victimization.     

Neuromuscular, biochemical and perceptual post-match fatigue in professional rugby league forwards and backs

In this study, we investigated changes in creatine kinase, perceptual and neuromuscular fatigue of professional rugby league players after match-play. Twenty-three male rugby league players (10 backs, 13 forwards) had their creatine kinase, perceptual ratings of fatigue, attitude to training, muscle soreness, and flight time in a countermovement jump measured before and 1 and 2 days after (day 1 and day 2 respectively) league matches. Total playing time, offensive and defensive contacts were also recorded for each player. Creatine kinase was higher both 1 and 2 days after than before matches (P < 0.05) in forwards and backs. Similarly, perceived fatigue and muscle soreness were higher than pre-match on both days 1 and 2 (P < 0.05), but did not differ between groups (P > 0.05). Jump performance was lower on day 1 but not day 2 for both groups (P < 0.05). While total playing time was longer in backs (P < 0.05), relative frequencies for all contacts were greater in forwards (P < 0.05). Contacts for forwards were correlated with all markers of fatigue (P < 0.05), but only flight time was correlated with offensive contacts in backs (P < 0.05). Despite the mechanisms of fatigue being different between forwards and backs, our results highlight the multidimensional nature of fatigue after a rugby league match and that these markers do not differ between positions.
