The purpose of this study was to investigate the association between selected skin-fold thicknesses and training variables with a half-marathon race time, for both male and female recreational runners, using bi- and multivariate analysis. In 52 men, two skin-fold thicknesses (abdominal and calf) were significantly and positively correlated with race time; whereas in 15 women, five (pectoral, mid-axilla, subscapular, abdominal, and suprailiac) showed positive and significant relations with total race time. In men, the mean weekly running distance, minimum distance run per week, maximum distance run per week, mean weekly hours of running, number of running training sessions per week, and mean speed of the training sessions were significantly and negatively related to total race time, but not in women. Interaction analyses suggested that race time was more strongly associated with anthropometry in women than men. Race time for the women was independently associated with the sum of eight skin-folds; but for the men, only the mean speed during training sessions was independently associated. Skin-fold thicknesses and training variables in these groups were differently related to race time according to their sex.  相似文献

Nuclear energy has received substantial recent attention, marketed as a ‘green’ solution to global climate change (GCC) with calls for new reactors. However, considerable debate exists about whether it represents a viable solution to GCC. Given the complexity and urgency of the issue, a full and balanced debate is desirable. Since media play an important role in shaping public perception, we examined print media coverage of proposed reactors in Georgia—one site in the southeastern United States, which has been the focus of such proposals. We analysed the content of editorials and news articles from two local newspapers—the Augusta Chronicle and Atlanta Journal‐Constitution. The former exclusively published pro‐nuclear opinion pieces whereas the latter published a mix of pro‐ and anti‐nuclear opinions. The majority of news articles in both newspapers generally presented balanced arguments. Pro‐ and anti‐nuclear arguments most often reflected economic and environmental benefits and risks, whereas informational text primarily detailed regulatory processes and financing. Findings suggested that informational text was not necessarily ‘neutral’, sometimes masking covert pro‐ and anti‐nuclear content. Implications for how findings might shape public opinion and strategies for shaping media and extending public deliberation are discussed. Copyright © 2010 John Wiley & Sons, Ltd.  相似文献

Reconsolidation studies have led to the hypothesis that memory, when labile, would be modified in order to incorporate new information. This view has reinstated original propositions suggesting that short-term memory provides the organism with an opportunity to evaluate and rearrange information before storing it, since it is concurrent with the labile state of consolidation. The Chasmagnathus associative memory model is used here to test whether during consolidation it is possible to change some attribute of recently acquired memories. In addition, it is tested whether these changes in behavioral memory features can be explained as modifications on the consolidating memory trace or as a consequence of a new memory trace. We show that short-term memory is, unlike long-term memory, not context specific. During this short period after learning, behavioral memory can be updated in order to incorporate new contextual information. We found that, during this period, the cycloheximide retrograde amnesic effect can be reverted by a single trial in a new context. Finally, by means of memory sensitivity to cycloheximide during consolidation and reconsolidation, we show that the learning of a new context (CS) during this short-term memory period builds up a new memory trace that sustains the behavioral memory update.  相似文献

It has been suggested that learning an object's location relative to (1) intramaze landmarks and (2) local boundaries is supported by parallel striatal and hippocampal systems, both of which rely upon input from a third system for orientation. However, little is known about the developmental trajectories of these systems' contributions to spatial learning. The present study tested 5- and 7-year-old children and adults on a water maze-like task in which all three types of cue were available. Participants had to remember the location of an object hidden in a circular bounded environment containing a moveable intramaze landmark and surrounded by distal cues. Children performed less accurately than adults, and showed a different pattern of error. While adults relied most on the stable cue provided by the boundary, children relied on both landmark and boundary cues similarly, suggesting a developmental increase in the weighting given to boundary cues. Further, adults were most accurate in coding angular information (dependent on distal cues), whereas children were most accurate in coding distance, suggesting a developing ability to use distal cues to orient. These results indicate that children as young as 5 years use boundary, intramaze landmark, and distal visual cues in parallel, but that the basic accuracy and relative weighting of these cues changes during subsequent development.  相似文献

Several runs of a cognitive-behavioral group-based training program for violent offenders in a youth detention center were evaluated. The training aims at reducing disposition towards violence, promoting responsibility and strengthening personal and social resources. The 49 participants were compared to 47 non-participating violent offenders. For the participants a reduction of several facets of aggression and an increase of responsibility for the offence was observed in a pre-post-comparison. However, treatment effects appear to decrease with longer observation time. Competencies such as empathy were not affected by the training. Furthermore, participants showed no difference to non-participants regarding officially recorded violent recidivism.  相似文献

Rawls’ principle of fair equality of opportunity has been regularly discussed and criticized for being inadequate regarding natural inequalities. In so far as this egalitarian goal is sound, the purpose of the paper is to see how the prospect of radical genetic intervention might affect this particular inadequacy. I propose that, in a post-genetic setting, an appropriate response would be to extend the same rules regulating societal inequalities to a regulation of comparable genetic inequalities. I defend this stance against recent arguments from the authors of From Chance to Choice and from Colin Farrelly’s alternative of the genetic difference principle. Thanks and appreciation to Dr. Pete Morris, Noreen McGuire and Ann Feeney for their support and encouragement. My thanks also to the participants of the Ninth Manchester Graduate (Brave New World 2005) Conference in Political Theory, where a shorter version of this paper was read.  相似文献

This article presents a pedagogical approach to training seminarians for faith leadership in the era of what Heidi Campbell has called “networked religion.” It argues that the increasing digital mediation of religious practice, expression, and community represents an opportunity for students to explore and inhabit ministry sites and roles from “within” the seminary classroom. Using education scholars' discussions of new digital geographies, gaming scholars' conception of game space, and reflection on classroom‐tested “quick challenges,” the author presents pedagogical principles for designing authentic new media learning experiences. Such activities bridge teaching spaces and ministry spaces to promote active learning through observation and immersion, simulation and role‐playing.  相似文献

A range of research studies has found that women report greater importance of religion and spirituality in their lives than men do. This study extends the literature on this phenomenon, and the theories that aim to explain it, by looking at whether gender differences in the three European countries (the United Kingdom, France, and Germany) differ by adult age group (young adults 18–39, midlifers 40–59, and older adults 60+), and by the cultural gender equality of the countries in question. Participants provided data on the importance of religiosity and spirituality to their life. Significant gender differences were found within all three countries, for each of the three age groups. In line with predictions based on Global Gender Gap Report 2016, Germany showed the smallest difference, followed by France and the United Kingdom. Gender differences were smaller in the young adult samples than for midlife adults or older adults.  相似文献

The goal of this study was to determine whether cluster analysis could be used to identify distinct subgroups of text message users based on behavioral economic indices of demand for text messaging. Cluster analysis is an analytic technique that attempts to categorize cases based on similarities across selected variables. Participants completed a questionnaire about mobile phone usage and a hypothetical texting demand task in which they indicated their likelihood of paying an extra charge to continue to send text messages. A hierarchical cluster analysis was conducted on behavioral economic indices, such as demand intensity, demand elasticity, breakpoint, and the maximum expenditure. With the cluster analysis, we identified 3 subgroups of text message users. The groups were characterized by (a) high intensity and low elasticity, (b) high intensity and medium elasticity, and (c) low intensity and high elasticity. In a demonstration of convergent validity, there were statistically significant and conceptually meaningful differences across the subgroups in various measures of mobile phone use and text messaging. Cluster analysis is a useful tool for identifying and profiling distinct, practically meaningful groups based on behavioral indices and could provide a framework for targeting interventions more efficiently.  相似文献

Based within a self-determination theory framework (SDT: Deci and Ryan, Intrinsic motivation and self-determination in human behaviour. Plenum Publishing Co., New York, 1985), the present study examined the effects of manipulating social-contextual conditions on the content of individuals’ self-talk. Seventy student volunteers were randomly assigned to a controlling or autonomy-supportive experimental condition. Participants were instructed to ‘think-aloud’ throughout a 10-min computerized task during which self-verbalizations were recorded. Audio recordings were transcribed verbatim, and then analysed using the Linguistic Inquiry and Word Count Program (LIWC; Pennebaker et al., LIWC2001; Linguistic Inquiry and Word Count (software and manual). Lawrence Erlbaum, Mahwah, NJ, 2001). Inductive content analyses were also conducted. Triangulation of the quantitative and qualitative findings revealed that in the autonomy-supportive condition, individuals’ self-talk was more informational and less controlling, with participants using more positive emotional words and assents, and fewer negative emotional words, swear words, and first person references than in the controlling condition. The findings suggest that social-context can affect cognitive factors such as self-talk and further support the promotion of autonomy-supportive environments.  相似文献
