Cognitive social learning mediators of aggression   总被引：4，自引：1，他引：4  

D G Perry  L C Perry  P Rasmussen 《Child development》1986,57(3):700-711

This research explored links between aggression in elementary school children and 2 classes of social cognitions that might influence children's decisions about whether to behave aggressively. Aggressive and nonaggressive children (mean age 11.3 years) responded to 2 questionnaires. One questionnaire measured children's perceptions of their abilities to perform aggression and related behaviors (perceptions of self-efficacy), and the other measured children's beliefs about the reinforcing and punishing consequences of aggression (response-outcome expectancies). Compared to nonaggressive children, aggressive subjects reported that it is easier to perform aggression and more difficult to inhibit aggressive impulses. Aggressive children also were more confident that aggression would produce tangible rewards and would reduce aversive treatment by others. There were negligible sex differences in perceived self-efficacy for aggression but large sex differences in anticipated social and personal consequences for aggression, with girls expecting aggression to cause more suffering in the victim and to be punished more severely by the peer group and by the self. It was concluded that children's knowledge of their capabilities and children's knowledge of the consequences of their actions are factors that need to be taken into account by cognitive models of aggression.  相似文献   

Learning-based summarisation of XML documents     

Massih R. Amini  Anastasios Tombros  Nicolas Usunier  Mounia Lalmas 《Information Retrieval》2007,10(3):233-255

Documents formatted in eXtensible Markup Language (XML) are available in collections of various document types. In this paper, we present an approach for the summarisation of XML documents. The novelty of this approach lies in that it is based on features not only from the content of documents, but also from their logical structure. We follow a machine learning, sentence extraction-based summarisation technique. To find which features are more effective for producing summaries, this approach views sentence extraction as an ordering task. We evaluated our summarisation model using the INEX and SUMMAC datasets. The results demonstrate that the inclusion of features from the logical structure of documents increases the effectiveness of the summariser, and that the learnable system is also effective and well-suited to the task of summarisation in the context of XML documents. Our approach is generic, and is therefore applicable, apart from entire documents, to elements of varying granularity within the XML tree. We view these results as a step towards the intelligent summarisation of XML documents.

A Distribution Free Interval Estimate for Coefficient Alpha     

Laura Trinchera  Nicolas Marie  George A. Marcoulides 《Structural equation modeling》2018,25(6):876-887

Scales are important tools for obtaining quantitative measures of theoretical constructs. Once a set of measures to be used in a scale is selected, reliability is commonly examined in order to assess their measurement quality. To date, Cronbach’s coefficient alpha is the most commonly reported index of measurement quality for assessing scale reliability. In this paper, an asymptotic distribution of the natural estimator of coefficient alpha is derived. A new interval estimate and a statistical test on the significance of the sample estimate of the coefficient are also presented. The proposed approach is compared to four popular methods commonly used to compute confidence intervals (CI) for alpha using a Monte Carlo simulation study. An R function for implementing the proposed CI approach is also provided.  相似文献   

Evaluation of Food Protection and Defense Outreach Education Programs     

John M. Shutske  Jennifer Pierquet  Laura Michel  Ruth Rasmussen  Debra Olson 《Journal of Food Science Education》2008,7(4):69-77

ABSTRACT: This analysis documents the outcomes and impacts from a series of food protection and defense educational programs conducted over a 3‐y period for private and public sector food system professionals. Several measures were used to determine the professions of participants; their improvements in skills and abilities that resulted from workshops; the audiences' most valued program content; practice changes resulting from educational program participation; abilities to recognize and change food system vulnerabilities; and changes in knowledge levels. Findings indicate that the knowledge level and interest within the target audience progressed over the 3‐y period from basic awareness level through more complex and higher order skills and competencies such as being able to walk through a food production, processing, distribution, or retail facility and identify specific vulnerabilities and make specific risk control recommendations. Pre‐ and posttest scores from the 3rd y of educational activities indicate that baseline awareness levels of core content on food protection and defense is now high among those most likely to attend these types of events, and that participants need to be challenged with additional higher‐level education to promote specific skills. This program series proved successful in building important relationships among food industry and regulatory partners. Analysis of the food security investigation (FSI) series will be useful in the development and delivery of new education and outreach efforts. It is hoped that the analysis and discussion will provide the motivation to further develop a set of competencies that can be used to ground educational efforts that focus on securing and defending our food system.  相似文献   

Willing to Think Hard? The Subjective Value of Cognitive Effort in Children          下载免费PDF全文

Nicolas Chevalier 《Child development》2018,89(4):1283-1295

Cognitive effort is costly and this cost likely influences the activities in which children engage. Yet, little is known about how school‐age children perceive cognitive effort. The subjective value of cognitive effort, that is, how valuable or costly effort is perceived, was investigated in seventy‐three 7‐ to 12‐year‐olds using an effort discounting paradigm. In two studies, it varied with task difficulty but not age, was predicted by actual effort engagement but not actual success and related to trait interest in effortful activities and proactive control engagement. Children are sensitive to cognitive effort and use it to guide behaviors, suggesting that poor performance may often reflect reluctance to engage cognitive effort rather than low ability.  相似文献   

Performance determinants of fixed gear cycling during criteriums     

Nicolas Babault  Maxime Poisson  Guiseppe Cimadoro  Carole Cometti  Christos Païzis 《European Journal of Sport Science》2018,18(9):1199-1207

Nowadays, fixed gear competitions on outdoor circuits such as criteriums are regularly organized worldwide. To date, no study has investigated this alternative form of cycling. The purpose of the present study was to examine fixed gear performance indexes and to characterize physiological determinants of fixed gear cyclists. This study was carried out in two parts. Part 1 (n?=?36) examined correlations between performance indexes obtained during a real fixed gear criterium (time trial, fastest laps, averaged lap time during races, fatigue indexes) and during a sprint track time trial. Part 2 (n?=?9) examined correlations between the recorded performance indexes and some aerobic and anaerobic performance outputs (VO_2max, maximal aerobic power, knee extensor and knee flexor maximal voluntary torque, vertical jump height and performance during a modified Wingate test). Results from Part 1 indicated significant correlations between fixed gear final performance (i.e. average lap time during the finals) and single lap time (time trial, fastest lap during races and sprint track time trial). In addition, results from Part 2 revealed significant correlations between fixed gear performance and aerobic indicators (VO_2max and maximal aerobic power). However, no significant relationship was obtained between fixed gear cycling and anaerobic qualities such as strength. Similarly to traditional cycling disciplines, we concluded that fixed gear cycling is mainly limited by aerobic capacity, particularly criteriums final performance. However, specific skills including technical competency should be considered.  相似文献
