Fathers’ influences on children’s development: The evidence from two-parent families     

Charlie Lewis  Michael E. Lamb 《European Journal of Psychology of Education - EJPE》2003,18(2):211-228

Although it is often assumed that men have an important influence on their children’s development, the supportive evidence can be difficult to locate and summarize. In this paper, we analyse the evidence with respect to four emergent themes. First, men often appear to interact with their children less sensitively than mothers do, and many children thus appear to form closer attachments to their mothers than to their fathers. Second, the data also indicate that fathers may play specific and important roles, with men in some cultures having clearly defined roles as playmates to their children. Third, paternal play styles predict later socio-emotional development while paternal involvement seems to predict adult adjustment better than maternal involvement does. Such evidence suggests, fourth, that we need appropriate measures of fatherhood that are not simply borrowed from the study of motherhood.  相似文献   

Transfer of oddity learning in the pigeon     

Richard Pisacreta  Paul Lefave  Tim Lesneski  Cathy Potter 《Learning & behavior》1985,13(4):403-414

Two pigeons were trained on a six-key modified oddity-from-sample procedure. The stimuli were olor pictures of birds, butterflies, and human faces. Initially, the third peck on the sample key which presented one of three different bird pictures) lit only one comparison key. Every three dditional pecks on the sample illuminated another comparison key. Fifteen sample pecks produced he maximum of five comparison stimuli. A peck on the comparison key that presented the non-atching bird picture produced grain. Pecks on matching keys turned off all the comparison keys nd repeated the trial. The birds learned to peck each sample until the non-matching comparison timulus was produced, and then to peck that key. After acquisition (70%–90% accuracy), the hree bird stimuli were replaced by a new set of three bird pictures. Subsequent phases provided ew sets of bird, butterfly, and human face stimuli. Both birds showed transfer of oddity learning o the novel samples. The data suggest that the birds may have been engaging in conceptual-type oddity learning, rather than learning discrete five-key discriminations or a series of two component chains.  相似文献   

Digital ITEMS Module 1: Reliability in Classical Test Theory          下载免费PDF全文

Charlie Lewis  Michael Chajewski  André A. Rupp 《Educational Measurement》2018,37(2):71-72

In this ITEMS module, we provide a two‐part introduction to the topic of reliability from the perspective of classical test theory (CTT). In the first part, which is directed primarily at beginning learners, we review and build on the content presented in the original didactic ITEMS article by Traub and Rowley (1991). Specifically, we discuss the notion of reliability as an intuitive everyday concept to lay the foundation for its formalization as a reliability coefficient via the basic CTT model. We then walk through the step‐by‐step computation of key reliability indices and discuss the data collection conditions under which each is most suitable. In the second part, which is directed primarily at intermediary learners, we present a distribution‐centered perspective on the same content. We discuss the associated assumptions of various CTT models ranging from parallel to congeneric, and review how these affect the choice of reliability statistics. Throughout the module, we use a customized Excel workbook with sample data and basic data manipulation functionalities to illustrate the computation of individual statistics and to allow for structured independent exploration. In addition, we provide quiz questions with diagnostic feedback as well as short videos that walk through sample exercises within the workbook.  相似文献   

温哥华冬奥会遗产工作研究及启示     

孙葆丽  宋晨翔  杜颖  张畅 《北京体育大学学报》2017,40(10):1-8

摘要：2010年温哥华冬奥会以其卓有成效的奥运遗产管理工作，成为推动奥林匹克运动可持续发展的典范。主要采用文献资料法、访谈法、实地考察法等研究方法，对温哥华冬奥会遗产的指导思想、组织体系和活动内容进行了分析与探讨。研究结果表明：温哥华冬奥会在奥林匹克运动历史上第一次提出了“创造”遗产的构想，并首次建立了专门的遗产管理机构，从而保证了奥运遗产工作有目的、有组织、有计划地运行。温哥华冬奥会还制定了分阶段进行不同侧重点遗产管理和运行的工作方案，确保了奥运遗产持续发挥作用，为奥林匹克运动和加拿大社会发展留下了宝贵财富，也为北京2022年冬奥会遗产管理和利用留下了可供借鉴的模式。  相似文献

Information needs and information sources of individuals living with spinal cord injury     

Burkell JA  Wolfe DL  Potter PJ  Jutai JW 《Health information and libraries journal》2006,23(4):257-265

AIMS AND OBJECTIVES: Access to health information is important for the well-being of people living in the community after spinal cord injury (SCI). In order to design appropriate information interventions, it is critical first to understand the information sources typically used. The goal of this study therefore is to identify the information-seeking practices of this group. SAMPLE AND METHODS: A sample of 207 individuals living in the community following traumatic spinal cord injury were surveyed regarding their ongoing information needs and practices for seeking information. RESULTS: The results reveal that respondents have unmet information needs, despite the fact that they typically access information through a variety of channels. SCI specialists are the most commonly used source, although they are viewed as relatively inaccessible. By contrast, the Internet (used by a relatively high proportion of respondents) is viewed as comparatively accessible, although there are some concerns about the quality of information found there. CONCLUSIONS: These survey results point to the need for an information source that is accessible and delivers high quality information. Although respondents use a variety of information sources, none meets this ideal profile. Information professionals should consider this gap in the design of information interventions.  相似文献

Factors associated with physical activity referral uptake and participation     

James DV  Johnston LH  Crone D  Sidford AH  Gidlow C  Morris C  Foster C 《Journal of sports sciences》2008,26(2):217-224

The aim of this study was to examine participant and scheme characteristics in relation to access, uptake, and participation in a physical activity referral scheme (PARS) using a prospective population-based longitudinal design. Participants (n = 3762) were recruited over a 3-year period. Logistic regression analyses identified the factors associated with the outcomes of referral uptake, participation, and completion (> or = 80% attendance). Participant's age, sex, referral reason, referring health professional, and type of leisure provider were the independent variables. Based on binary logistic regression analysis (n = 2631), only primary referral reason was associated with the PARS coordinator making contact with the participants. In addition to the influence of referral reason, females were also more likely (odds ratio 1.250, 95% confidence interval 1.003-1.559, P = 0.047) to agree to be assigned to a leisure provider. Referral reason and referring health professional were associated with taking up a referral opportunity. Older participants (1.016, 1.010-1.023, P < 0.001) and males were more likely to complete the referral. In conclusion, the PARS format may be less appropriate for those more constrained by time (women, young adults) and those with certain referral reasons (overweight/obesity, mental health conditions). More appropriate targeting at the point of referral could improve participation rates by revealing or addressing barriers that might later result in dropout.  相似文献   

Patterns of preschool provision in English local authorities 1     

Charlie Owen  Peter Moss 《教育政策杂志》2013,28(4):309-328

It is estimated that in 1986 40‐50% of children in England aged 3 and 4 were attending pre‐school playgroups. Another 20% were receiving education in nursery schools and classes, mostly part time, whilst a further 20% were in the reception classes of infant schools, mostly full time. Using data on the provision of these services within each local authority in England it is shown that the numbers of nursery education and of playgroup places are strongly negatively correlated. Combining these statistics with data from the 1981 Census it is also shown that the rates of provision are strongly related to the socio‐economic characteristics of the authorities, such that playgroups predominate in the more affluent areas whereas high levels of nursery education are found in urban areas with more material disadvantage.
