Measuring Relational Reasoning

Relational reasoning is the foundational cognitive ability to discern meaningful patterns within an informational stream, but its reliable and valid measurement remains problematic. In this investigation, the measurement of relational reasoning unfolded in three stages. Stage 1 entailed the establishment of a research-based conceptualization of the construct and the development of a corresponding Test of Relational Reasoning (TORR). Stage 2 focused on the reliability and validity of data from the TORR. Analyses showed the data from the TORR to be reliable indicators of students' ability to reason relationally, and TORR performance predicted students' performance on SAT verbal and math problems. Stage 3 examined the underlying structure of the construct through Confirmatory Factor Analysis (CFA). Of the three CFA models tested, models with dedicated factors for analogical, anomalous, antinomous, and antithetical reasoning were deemed the best fit for the data.     

Representation of morality in children: A qualitative approach

ABSTRACT

Previous research on children’s moral reasoning usually used a quantitative approach and a pre-determined set of methods in order to establish early moral landmarks. We proposed a qualitative perspective on the basis of which we have formulated three main objectives: 1) to identify the main categories of behaviors that children spontaneously associate with the notion of morality, in line with Turiel’s Domain Theory; 2) to investigate children’s conceptions of moral and social-conventional rules and 3) to assess the gender differences in the use of care and justice reasoning, in line with Gilligan’s assertion that females are care-oriented and that males consistently use the justice orientation and infrequently use the care orientation. Ninety-two children (57% boys, mean age was 8.19 years) were required to describe morality in behavioral terms without being guided by specific indications from the researchers. Our results reflected a tendency towards morality perceived through behaviors directed towards others, namely through altruism, and also the domination of moral norms as compared to social ones, partially confirming Gilligan’s theory concerning gender specificities regarding moral reasoning in the questions of care and justice.

Analyzing and Integrating Models of Multiple Text Comprehension

We introduce a special issue featuring four theoretical models of multiple text comprehension. We present a central framework for conceptualizing the four models in this special issue. Specifically, we chart the models according to how they consider learner, texts, task, and context factors in explaining multiple text comprehension. In addition, the models are contrasted along three dimensions capturing different orientations toward multiple text comprehension. Models in the special issue are described as more behaviorally or cognitively focused, as conceptualizing multiple text comprehension as an internally driven or an externally triggered process, and as directly responsive to or indirectly influenced by task. The importance and relevance of this special issue for research on multiple text comprehension are discussed.     

Supporting students with impairments in higher education: social inclusion or cold comfort?

This paper uses a discursive analysis to examine the experience of ‘inclusion’ from several stakeholder groups in one university. The research team included disability support staff at the institution, external disability consultants and academic researchers. A critical focus group investigation centred on four groups: students who were identified as having an impairment (SWIs), academic staff (teachers), administrators and students who did not identify as having an impairment (non‐SWIs). Interviews had facilitators with both research and disability expertise. Groups recounted different experiences of inclusion. SWIs, drawing on a rights discourse, emphasised a lack of resourcing and barriers created by the teaching staff. In contrast, teachers, administrators and (to a lesser extent) non‐SWIs emphasised the importance of social inclusion, reflecting discourses around needs and humanist notions of care and support, which largely seemed to miss the core of SWI concerns about recognition of their technical competence. For all groups, questions around disclosure of disability were of greater concern than tensions between needs and rights or the recent publication of a Code of Practice for the higher education sector. The findings challenged some of the researchers’ own assumptions, with unexpected implications for practice.     

Motivation and Self-regulation in Community College Transfer Students at a Four-year Online University

ABSTRACT

Motivation and self-regulation were examined in a sample of community college transfer students enrolled in a 4-year, online university. The relation between motivation and self-regulation and students’ performance was examined, as was the association between these learner characteristics (i.e., motivation and self-regulation) and sociodemographic factors (e.g., marital status, employment status). Motivation was found to be significantly correlated with both semester and cumulative grade point average (GPA), while associations between self-regulation and performance were more limited. Further, motivation was found to be a significant predictor of semester GPA in a model controlling for sociodemographic factors and prior achievement. Motivation and self-regulation were also found to differ according to students’ sociodemographic status. For instance, transfer students with children under 18 were found to have significantly higher levels of motivation than nonparents. Those employed full-time had lower levels of self-regulation than did their nonemployed peers. Implications for further research on community college transfer students and online learning are discussed.     

The angiogenetic effect of intramuscular administration of b-FGF and a-FGF on cardiac muscle: The influence of exercise on muscle angiogenesis

Abstract

Although angiogenetic therapy using recombinant growth factors holds much hope for the treatment of ischaemic diseases, there are still many unanswered questions, including the method of administration, the correct dose of these factors, and the duration of the therapeutic approach. Exercise has also been suggested to induce neovascularizaiton in muscles. We evaluated the angiogenetic effects of the intramuscular administration of basic-fibroblast growth factor (b-FGF) and acidic-fibroblast growth factor (a-FGF) in rat heart, compared with rats who exercised daily. In conclusion, both the intramuscular administration of b-FGF and exercise increased significantly angiogenesis in the heart in contrast to the intramuscular administration of a-FGF, which was ineffective.     

The microcycle of inflammation and performance changes after a basketball match

Abstract

Basketball incorporates intense eccentric muscle activity that induces muscle microtrauma and an inflammatory response. This study investigated time-dependent inflammatory and performance responses during a weekly microcycle after a basketball match. Twenty elite-standard players underwent a trial that comprised a match followed by a 6-day simulated in-season microcycle. The trial was preceded by a control condition that did not have a match. Blood sampling and tests of maximal-intensity exercise performance and muscle damage occurred before each condition, immediately after the match and daily thereafter for 6 consecutive days. The match induced marked increases in heart rate, lactate, ammonia, glucose, non-esterified fatty acids and triglycerides. Performance deteriorated for 24–48 h after the match, whereas knee flexor and extensor soreness increased for 48 and 24 h post-match, respectively. Inflammatory (leukocytes, C-reactive protein, creatine kinase activity, adhesion molecules, cortisol, uric acid and cytokines) and oxidative stress (malondialdehyde, protein carbonyls, oxidised glutathione, antioxidant capacity, catalase and glutathione peroxidase) markers increased for ~24 h and subsided thereafter. Reduced glutathione declined for 24 h after exercise. These results suggest that a basketball match elicits moderate and relatively brief (~24–48 h) inflammatory responses, is associated with marked but short-lived performance deterioration, but is less stressful than other intermittent-type sports.
