The study examined how preschool intervention programmes set up by three Scottish local authorities changed parents’ cognitions. Quantitative parent outcomes were measured using Parenting Daily Hassles Scales (N = 88). A matched comparison group of parents (N = 55) recruited from the same areas of disadvantage but whose children did not attend the intervention programmes also completed questionnaires. Qualitative outcomes were evaluated using semi‐structured interviews (N = 30). A significant group × time interaction effect was found for daily hassle cognitions, Parenting Task–Intensity, Challenging Behaviour–Frequency and Challenging Behaviour–Intensity, with comparison group parents showing an increase in their experience of hassles during the ‘terrible twos’ compared with intervention group parents. Complementary qualitative data indicated that intervention group parents had gained valuable new insights into their children’s behaviour, changing how they thought about their role as parents and their behavioural and developmental expectations of their children. Implications for parental engagement in preschool programmes are discussed. 相似文献

The discovery of the electron in 1897 deeply impacted the nature of chemistry in the twentieth century. A revolution in the theoretical structure of chemistry as well as in the instrumental tools used in chemical analysis occurred as a result of this discovery. The impact of this revolution on tin oxide chemistry over approximately a 100 year period is the focus of this paper. Important questions addressed include the following: Are tin oxides of importance in our current society or are they only of quaint academic interest? In what way has chemistry as a discipline added to our understanding of the tin oxides and has this added any technological value to these compounds? Does the historical approach followed in this paper offer chemistry educators the opportunity to place current chemical knowledge in a broader epistemological framework? The impact of the answers to these questions on chemistry education is discussed. 相似文献

Questions about identity and future success often occupy the thinking of individuals during life transitions. Possible-selves theory describes how future-oriented thought provides identity-relevant information and motivation to pursue self-relevant goals. Expected and feared possible selves of beginning teachers (n = 221) were analyzed revealing four main categories (i.e., interpersonal relationships, classroom management, instruction, and professionalism). Differences between student and beginning inservice teachers suggest a transitional trajectory that could have implications for understanding the “how” of teacher identity development. Possible-selves theory may help bring a degree of unity across divergent frameworks and help link identity to broader issues of teacher development. 相似文献

Abstract In an era in which genomes are being sequenced and support for traditional biological collections is diminishing, it's a dynamic time to be an academic curator in biology. Pressures arise from factors such as bureaucracy, from the need to document productivity in terms that largely neglect collections, from the seeming discord between taxonomic orientation and hypothesis testing, reliance on soft money, teaching and research, and the need to build collections. Some of us prefer to continue building collections nonetheless. These factors combine to produce unprecedented levels of stress on academic curators. However, these seas can be navigated, and doing so brings both traditional and nontraditional rewards. This article presents a personal working study in navigating this increasingly complex career choice. 相似文献

This article describes the conceptualisation and development of a pedagogical framework to support the design of e‐books for children to enhance literacy development. It emerged from research undertaken within the Q‐Tales international consortium project of the EU's Horizon 2020 Programme for Research and Innovation, where the aim was to facilitate key stakeholders to collaborate and participate in the online production and publication of high‐quality, educational e‐books for children. The pedagogical framework described here sought to answer the question “What concepts and principles undergird the effective design of pedagogically impactful e‐books for children?” It is grounded by the theoretical underpinnings of socio‐constructivism, constructionism and skill theory, and how they relate to children's literacy development. A framework describing different narrative forms and component features, key pedagogical activities appropriate for different stages of reading development and design recommendations regarding the integration of multimedia into e‐books are also central to the pedagogical framework. As well as informing the design of the Q‐Tales infrastructure for children's e‐book design and publication, we hope the guidelines and pedagogical activities enumerated here will be widely useful for those designing and developing digital, interactive narratives, particularly e‐books to enhance children's emerging literacy. 相似文献

Anterior cruciate ligament (ACL) injury prevention programmes have not been as successful at reducing injury rates in women’s basketball as in soccer. This randomised controlled trial (ClinicalTrials.gov #NCT02530333) compared biomechanical adaptations in basketball and soccer players during jump-landing activities after an ACL injury prevention programme. Eighty-seven athletes were cluster randomised into intervention (6-week programme) and control groups. Three-dimensional biomechanical analyses of drop vertical jump (DVJ), double- (SAG-DL) and single-leg (SAG-SL) sagittal, and double- (FRONT-DL) and single-leg (FRONT-SL) frontal plane jump landing tasks were tested before and after the intervention. Peak angles, excursions, and joint moments were analysed using two-way MANCOVAs of post-test scores while controlling for pre-test scores. During SAG-SL the basketball intervention group exhibited increased peak knee abduction angles (p = .004) and excursions (p = .003) compared to the basketball control group (p = .01) and soccer intervention group (p = .01). During FRONT-SL, the basketball intervention group exhibited greater knee flexion excursion after training than the control group (p = .01), but not the soccer intervention group (p = .11). Although women’s soccer players exhibit greater improvements in knee abduction kinematics than basketball players, these athletes largely exhibit similar biomechanical adaptations to ACL injury prevention programmes. 相似文献

Although sport management researchers concur with one another regarding the significance of interaction between employees and consumers in shaping the consumers’ attitudes and behaviors, the vast majority of previous studies are largely isolated such that they take assessment exclusively from one side of the dyad—either employees or consumers. The authors seek to advance the current body of knowledge by utilizing a dyadic method that includes judgments provided by employees as well as one of each employee’s consumers in a high-contact sport service context (i.e., multi-purpose fitness centers). As such, the authors investigate how employee citizenship behavior and deviance behavior influence consumer citizenship behavior and participative behavior through consumers’ perceived service quality and satisfaction with employees. The results indicated that employee citizenship behavior positively and deviance behavior negatively shaped consumers’ perceptions of service quality, whereas the negative moderating effect of employee deviance behavior between employee citizenship behavior and service quality was not supported. Satisfaction with employees significantly mediated the relationship between service quality and consumer citizenship behavior but not between service quality and consumer participative behavior. Theoretical, methodological, and practical implications derived from this study are discussed. 相似文献

This investigation examined the effect of beetroot juice (BR) supplementation, a source of dietary nitrate (NO3?), on cycling time-trial (TT) performance and thermoregulation in the heat. In a double-blind, repeated-measures design, 12 male cyclists (age 26.6 ± 4.4 years, VO2peak 65.8 ± 5.5 mL.kg?1.min?1) completed four cycling TTs (14 kJ.kg?1) in hot (35°C, 48% relative humidity) and euthermic (21°C, 52%) conditions, following 3 days supplementation with BR (6.5 mmol NO3? for 2 days and 13 mmol NO3? on the final day), or NO3–depleted placebo (PLA). Salivary NO3? and nitrite, core (Tc) and mean skin temperature (Tsk) were measured. Salivary NO3? and nitrite increased significantly post-BR supplementation (p < 0.001). Average TT completion time (mm:ss) in hot conditions was 56:50 ± 05:08 with BR, compared with 58:30 ± 04:48 with PLA (p = 0.178). In euthermic conditions, average completion time was 53:09 ± 04:35 with BR, compared with 54:01 ± 04:05 with PLA (p = 0.380). The TT performance decreased (p < 0.001), and Tc (p < 0.001) and Tsk (p < 0.001) were higher in hot compared with euthermic conditions. In summary, BR supplementation has no significant effect on cycling TT performance in the heat. 相似文献

This study assessed the influence of training load, exposure to match play and sleep duration on two daily wellbeing measures in youth athletes. Forty-eight youth athletes (age 17.3 ± 0.5 years) completed a daily wellbeing questionnaire (DWB), the Perceived Recovery Status scale (PRS), and provided details on the previous day’s training loads (TL) and self-reported sleep duration (sleep) every day for 13 weeks (n = 2727). Linear mixed models assessed the effect of TL, exposure to match play and sleep on DWB and PRS. An increase in TL had a most likely small effect on muscle soreness (d = ?0.43;± 0.10) and PRS (d = ?0.37;± 0.09). Match play had a likely small additive effect on muscle soreness (d = ?0.26;± 0.09) and PRS (d = ?0.25;± 0.08). An increase in sleep had a most likely moderate effect on sleep quality (d = 0.80;± 0.14); a most likely small effect on DWB (d = 0.45;± 0.09) and fatigue (d = 0.42;± 0.11); and a likely small effect on PRS (d = 0.25;± 0.09). All other effects were trivial or did not reach the pre-determined threshold for practical significance. The influence of sleep on multiple DWB subscales and the PRS suggests that practitioners should consider the recovery of an athlete alongside the training stress imposed when considering deviations in wellbeing measures. 相似文献

Robert Putnam’s conceptualization of social capital has been commonly associated with, and used to analyse, sport-for-development programmes. This paper bucks this trend and uses James Coleman’s rational strain of social capital to examine the use of sport as a component part of a programme to support male adults in addressing connected problems of substance misuse, homelessness and other forms of social exclusion. Using a qualitative research strategy, in-depth and longitudinal data were collected using individual interviews and focus groups with programme participants and key stakeholders over a three-year period. The results suggest the importance of unintentionality for the formation and use value of social capital; indicating that social capital created through this programme was individual, contingent on interactional context and benefited individuals in line with Coleman’s six aspects of social capital. 相似文献
