Objective. Children vary in how sensitive they are to environmental influences. Child temperament is an individual difference factor that appears to moderate the impact of environment on early child development. This study contrasts the “diathesis-stress/dual risk” and “differential susceptibility” models in examining difficult temperament as a moderator of the relation between preschool parenting and school-aged child persistence. Design. A longitudinal design included 61 typically developing Portuguese children (31 girls) assessed when they were toddlers (Time 1 at 1–3 years), preschoolers (Time 2 at 4–6 years), and school aged (Time 3 at 8–10 years). At Time 1, parents were recruited and interviewed. At Time 2, semi-structured mother–child interactions were observed, and preschool teachers rated children’s temperament. At Time 3, children’s task persistence was rated by their elementary teachers. Results. Difficult temperament moderated the association between mother–child interactions and child persistence, with stronger associations for children with more difficult temperaments. Conclusions. Consistent with the diathesis-stress model, results reveal that high levels of positive parenting reduce the risk of low self-regulation associated with difficult temperament.  相似文献

Abstract

The purpose of this study was to investigate the association between relay exchange block time and final performance in 4 × 100-m and 4 × 200-m freestyle and 4 × 100-m medley relays as a function of sex (men and women) and classification (medallists and non-medallists) in international competitions. Nineteen international competitions covering a 13-year period (2000–2012) were analysed retrospectively. The data corresponded to a total of 827 team relay histories (407 men, 420 women). Kruskal–Wallis and Mann–Whitney tests were performed to determine any differences by sex, classification, and event. Similarly, the relationship between the exchange block times and final performance was examined by means of a Pearson correlation analysis. In the three events, the men’s exchange block times were shorter than those of the women (η2 = 0.049–0.109; < 0.001). The exchange block time was especially relevant for the women’s relay medallists in the 4 × 100-m freestyle (= 0.306, = 0.021) and 4 × 100-m medley (= 0.385, = 0.011), while for men the relationship was clearer for the non-medallists. These results suggest that the exchange block time should be considered as one of the performance parameters of swimming relay starts, and thus should be included explicitly as part of training. In particular, the coach could design training targeted at standardising an optimal exchange block time equal to or less than that expected for other teams in the competition.  相似文献

Over the last few years, information and communication technologies have become an essential part of daily life, affecting education, employment, and leisure, among other activities. Nonetheless, many individuals still reap few or no benefits from these technologies, and there are resilient gaps in their use. Within this larger context, the authors examine the Internet digital divide between people with and without disabilities from a multidimensional approach. Rather than analyzing the gap in terms of “haves” and “have-nots,” a range of Internet-related dimensions—affordability, motivation and attitudes, skills, usage, and others—is taken into account.  相似文献

Existing university ranking systems blur differences between Higher Education Institutions because they only focus on research. The increased breadth, diversity and complexity of Higher Education Institutions’ missions are repeatedly overlooked causing a low visibility to a wide audience. This paper demonstrates the possibilities to measure other missions such as international orientation and regional engagement. Therefore, the results of 618 Higher Education Institutions (Effective March 2016) in U-Multirank, an international university ranking, are used. The results show the impressive variety in the higher education systems among European regions. Every region found missions in which they effectively perform thus proving the importance of each mission. The multidimensional ranking takes into account the complexity of Higher Education Institutions’ missions and capturing the relevance of Higher Education Institutions third mission’s activities adequately. Transparency across all missions is the only possibility to make the performances honourable. As research is not the only remarkable mission of Higher Education Institutions, teaching is not the only necessary mission. When other missions are overlooked, the performance measurement systems hinder mission diversity in higher education.

In this paper, we analyse the aims, contents and impact of Seabra’s two-volume textbook – Elementos de Chimica (Elements of Chemistry) – published in 1788 and 1790. Seabra’s Elements of Chemistry does not conform to the characteristics usually ascribed to textbooks by traditional historiography, and in particular to textbooks published in the peripheries. Marking the arrival of the new chemistry in Portugal, in a period in which many still resisted Lavoisier’s chemistry, this textbook was a state of the art account written in Portuguese, interspersed with critical evaluations, original comments and novel contributions. Despite being the only Portuguese chemistry textbook written during this period, it had hardly any readers, even among its natural audience at the University of Coimbra.  相似文献

In two experiments, rats received preexposure consisting of six intraperitoneal injections of lithium chloride (LiCl). This treatment reduced the magnitude of the unconditioned response (UR; suppressed consumption of a novel flavor) evoked by an additional injection (Experiment 1) or by oral consumption (Experiment 2) of LiCl. In both experiments, preexposure also attenuated the acquisition of a conditioned aversion with an LiCl injection as the unconditioned stimulus (US) but had no effect on the aversion produced when the US was oral consumption of LiCl (Experiment 2). These results are consistent with the view that the reduced ability of the preexposed US to serve as a reinforcer depends on blocking by injection-related cues and is independent of habituation of the UR recorded in the present study. Possible interpretations of this dissociation are discussed.  相似文献

This article aims to shed light on the current debate regarding the role of internships in higher education in graduates’ employability. In specific, it analyses empirical data on a large-scale study of Portuguese first-cycle study programmes, in order to explore indicators of the professional value of internships in the employability of higher education graduates. Results demonstrate that study programmes that include internships tend to significantly enhance graduates’ employability, particularly within the universe of polytechnic and public higher education institutions. Besides the instrumental value of internships, the impact of the nature and structure of the internship on the percentage of unemployed graduates are also discussed. Mandatory internships and the inclusion of multiple, shorter internships throughout the degree are negatively associated with unemployment levels. Results indicate work-based learning can be used as a successful strategy to bridge theoretical knowledge and practice and enhance graduate employability. These findings provide important insights for the evaluation and/or the design of internship programmes in higher education.  相似文献

As a teaching method, tutorials are fundamental to university education, and are underpinned by the following goals: to accompany students; to help them establish a clear training pathway; and to promote their academic achievement. Our proposal aims to introduce psychological aspects into the Tutorial Action Plan (TAP) which, while often left unattended, are closely related to academic achievement. Our objective is to identify the relation between the academic commitment of pre-service teachers (preschool education, primary education and double degree students) at the UB and stress and coping skills, academic motivation, achievement and self-efficacy, as well as the opinions of students and tutors on the resources used during TAP and potential improvements to it. This is a transversal prospective exploratory study, applying the following questionnaires: Academic commitment (UWESS-9); Perceived Stress Scale (PSS); Self-efficacy (NGSE); Motivation (MSLQ); and two ad hoc online questionnaires. In conclusion, we hope that the results of this study will help us reformulate the TAP of said degree programmes, improving personalized attention and the quality of the student tutorial system, which is one of the standards used to assess universities.  相似文献
