Young Children's Trust Beliefs in Peers: Relations to Social Competence and Interactive Behaviors in a Peer Group     

Jui-Chih Chin 《Early education and development》2014,25(5):601-618

Research Findings: The aim of this study was to explore the relations between children's trust beliefs and social competence as well as social preference. In addition, this study examined how children with different trust belief profiles may differ in their peer interactive behaviors. A total of 47 children ages 5 to 6 participated in this study. Data were collected via observation of play behaviors, a teacher-rated social competence scale, and a child interview. The results indicated that children's trust beliefs in friends’ promise-keeping behaviors were positively associated with intrapersonal and interpersonal domains of social competence. Children who had greater trust in non-friend classmates’ promise-keeping behaviors tended to be sociable in a group, polite, and more preferred, and they were less likely to be disliked by peers. Children with different trust profiles exhibited differential interactive behaviors with peers. Practice or Policy: These findings suggest that parents and early childhood educators should pay more attention to the extent to which young children trust their close friends and familiar peers, especially in terms of keeping promises. Adults may model their efforts in keeping their promises made to children and enhance children's capacity to reciprocate trust in close relationships. Adults can help children differentiate their trust based on the intimacy of relationships.  相似文献   

Risky business: Students and smartphones     

Beth H. Jones  Amita Goyal Chin  Peter Aiken 《TechTrends》2014,58(6):73-83

The increase in smartphone adoption has been no less than astounding. Unfortunately, the explosive growth has been accompanied by a rash of security problems. A contributing factor to the growing security problem is a lack of education, training, and awareness. In addition, “bring your own device” (BYOD) policies often leave security responsibilities to the competencies of device owners, which compromises security. Today’s students are tomorrow’s employees with responsibilities for protecting their work environment. They need to understand and practice a full-range of mobile security practices so that they can safely access the information assets of their organizations. If students are not engaging in such practices, educational institutions have a responsibility to ensure that students understand how to keep information assets secure. This paper investigates the smartphone security practices of undergraduate college students. Five hundred students in business classes at a regional public university were surveyed to determine their use of recommended smartphone security practices. The study found that many smartphone users did employ some security measures, but a high percentage of them were ignoring potential risks. This suggests a need for increased education, training, and awareness.  相似文献   

Academic social bookmarking: An empirical analysis of Connotea users     

Helen S. Du  Samuel K.W. Chu  Gary E. Gorman  Felix L.C. Siu 《Library & information science research》2014

Three groups of social bookmarking users, namely experienced users, users with moderate level of experience, and novice users, were investigated, in terms of their reported tagging behaviors, perceived usefulness of social bookmarking in information discovery and management, and perceived usefulness of the bookmarking features provided. Based on the empirical analysis of the Connotea users, who are primarily in academia, the study shows that experienced academic users generally prefer to use social bookmarking while moderately experienced and novice users still prefer to use the traditional bookmarking methods, such as creating and using bookmarks on a dedicated computer. Experienced academic users were also found to create more tags per bookmark comparing to the other two groups. Most novice academic users, however, only created one tag per bookmark, which just met Connotea's minimum requirement. Surprisingly different from the collaborative design nature of the social bookmarking systems, the study finds that our participants, particularly experienced academic users, prefer to create and use their own bookmarks rather than sharing bookmarks created by others. In fact, experienced users have significantly higher frequency (once every two weeks) of creating bookmarks than the other two groups (once a month or less). In addition, website design features and functions, such as automatic collection of bibliographic information, are regarded by all participants as helpful for information discovery. The in-depth examination and discussion of the opinions of Connotea users may be useful for further improvement of the design features and usage applications, particularly for academic social bookmarking websites. The results may also have potential implications to the future development of social bookmarking services in general.  相似文献   

SYSTEM ACTIVITIES AND EDUCATION     

Felix I. Peregudov 《Higher Education in Europe》1990,15(4):86-96

A paradoxical situation has emerged as new conditions of human interaction affirm themselves. Even though precise knowledge is available, we seem to be unable to put it to efficient use and to invest it in practical undertakings. The professional incompetence and functional illiteracy of otherwise educated people, decision‐makers included, have reached massive proportions.  相似文献   

Microfluidic three-dimensional hydrodynamic flow focusing for the rapid protein concentration analysis     

Sungmin Hong  Pei-Hsiang Tsou  Chao-Kai Chou  Hirohito Yamaguchi  Chin B. Su  Mien-Chie Hung  Jun Kameoka 《Biomicrofluidics》2012,6(2)

A simple microfluidic 3D hydrodynamic flow focusing device has been developed and demonstrated quantitative determinations of quantum dot 525 with antibody (QD525-antibody) and hemagglutinin epitope tagged MAX (HA-MAX) protein concentrations. This device had a step depth cross junction structure at a hydrodynamic flow focusing point at which the analyte stream was flowed into a main detection channel and pinched not only horizontally but also vertically by two sheath streams. As a result, a triangular cross-sectional flow profile of the analyte stream was formed and the laser was focused on the top of the triangular shaped analyte stream. Since the detection volume was smaller than the radius of laser spot, a photon burst histogram showed Gaussian distribution, which was necessary for the quantitative analysis of protein concentration. By using this approach, a linear concentration curve of QD525-antibody down to 10 pM was demonstrated. In addition, the concentration of HA-MAX protein in HEK293 cell lysate was determined as 0.283 ± 0.015 nM. This approach requires for only 1 min determining protein concentration. As the best of our knowledge, this is the first time to determinate protein concentration by using single molecule detection techniques.  相似文献

A Comparison of Approaches for the Analysis of Interaction Effects Between Latent Variables Using Partial Least Squares Path Modeling     

Jörg Henseler  Wynne W. Chin 《Structural equation modeling》2013,20(1):82-109

Although stratification in the workplace has received considerable attention in the literature on organizations, there is little systematic understanding about how individual and structural characteristics act to produce a stratified workplace. This study focuses on understanding the dynamics of workplace attainment by examining stratification within higher education administration. The purpose of the study is twofold—(a) to propose and test a model concerning how organizational and individual variables affect workplace attainment and (b) to demonstrate the application of structural equation modeling in estimating and testing this model. Results are discussed in terms of their theoretical significance and practical implications.  相似文献   

Parental Expressivity,Child Physiological and Behavioral Regulation,and Child Adjustment: Testing a Three-Path Mediation Model     

Jeffrey Liew  Audrea Y. Johnson  Tracy R. Smith  Felix Thoemmes 《Early education and development》2013,24(4):549-573

Research Findings: Parental expressivity, child physiological regulation (indexed by respiratory sinus arrhythmia suppression), child behavioral regulation, and child adjustment outcomes were examined in 45 children (M age = 4.32 years, SD = 1.30) and their parents. With the exception of child adjustment (i.e., internalizing and externalizing problems and adaptive skills), which were assessed with parents' ratings, all variables were observed behaviorally or physiologically. A 3-path mediation path model was tested with the relations between parental expressivity and child adjustment outcomes mediated through child physiological regulation and behavioral regulation. Despite low power to detect the mediated effect, there was evidence to suggest that physiological regulation and behavioral regulation were 2 mediating mechanisms by which parental high positive/low negative expressivity may influence adaptive skills. Thus, parental expressivity may shape children's physiological regulation. And physiological regulation may be 1 mechanism by which effortful control becomes manifested as behavioral regulation that becomes apparent to others who then make evaluations about individuals' adaptive skills. Practice or Policy: The results have implications for interventions aimed at parent training or parental coaching of emotion as well as interventions aimed at enhancing children's social-emotional or behavioral regulation to improve children's adaptive skills.  相似文献   

Conservation of stained glass windows with protective glazing: Main results from the European VIDRIO research programme

The methodology of protecting the European stained glass windows against environmental risk (e.g. meteorological factors, air pollution, microorganisms) by means of an external glazing is not new. In spite of many scientific studies carried out in the last 20 years, some questions were still up for discussion. The European VIDRIO (2002–2005) project gave an answer to these questions. The research carried out by the different project partners established a new multidisciplinary approach aimed at evaluating the efficiency of the protective glazing systems and their effects on stained glass windows conservation, and finally at assessing the most appropriate strategy to preserve stained glass windows. Scientific results showed that the so-called isothermal glazing (i.e. ventilation by the air coming from the inside of the building) protected efficiently the ancient stained glass window from environmental attack (i.e. rain, pollutants, condensation, thermal shocks) with very limited secondary effects. The scientific research highlighted that its efficiency was strongly related to the technical design of the protective system. In particular, the ventilation and the size of the interspace had to be carefully considered. The research developed within the VIDRIO project was turned into general recommendations to the owners and practitioners on the best practice for the stained glass windows future conservation.  相似文献
