In the United Kingdom (UK), professional female football has grown exponentially in recent years, including with the advent of the Women's Super League. Given this growth, the present study aimed to (a) to explore the junior-to-senior transition in the UK female football players (i.e., perceived demands, barriers, resources, and coping strategies); (b) to analyze how changes in the UK female football context (i.e., increased professionalization) influenced players' perception of the transition. Six professional female soccer players from two groups took part in the study; senior athlete (N = 3) and transitional athletes (N = 3). To acquire a holistic understanding, semi-structured interviews were conducted with all athletes. Results highlighted transitional athletes appeared to have a different JST experience compared to the senior group, with the difference in experience attributed to the increased professionalization of female football. In particular, demands associated with being a dual career athlete and greater difficulty balancing the competing demands. As a result, transitional athletes also engaged in more coping strategies. This study provides valuable findings in relation to the JST in professional female football and the context of the increasing professionalization of female football in the UK.  相似文献

以往的实证和理论研究对幸福感稳定性与变化性问题持有不同观点。设定点理论认为幸福感通常保持在设定点位置, 动态平衡理论(及其变式——主观幸福感稳态理论)进一步强调幸福感在围绕设定点的某个范围内波动而呈动态平衡状态, 享乐适应理论在动态平衡理论基础上从情绪适应的角度分析了幸福感维持稳定的原因, 这三个理论均强调幸福感维持在某个平衡水平。相反, 持续幸福理论强调幸福感是可以提升的, 能发生长期的变化。这些理论观点的差异本质在于如何看待幸福感的稳定性与变化性, 我们借用生物学中的“稳态”“稳态应激”概念及物理学中的“跃迁”思想, 认为幸福感不仅存在稳态, 也会出现稳态应激, 并可由此引起幸福感稳态的跃升。这一整合视角为幸福感研究提供了新的解释框架, 也对幸福感的持续提升有启发意义。  相似文献

Through a joint community effort Denmark’s Renewable Energy Island Samsø became self-sufficient with renewable energy over a period of 10 years from 1997 to 2007. Today, the story about Samsø’s successful energy transition has become a global export and a widely known model of community building, public participation and shared ownership in renewable energy technologies and transition processes. What has allowed the Samsø narrative to travel so widely has been the effective ‘transition story’ created about the islanders’ efforts. This transition story, however, has become fixed with the years and has assumed an ideal-typical character. Meanwhile, the challenges and costs inherent in the complicated socio-material process of transition are underestimated and largely forgotten. While such transition stories are indeed inspiring, the ideal-typical narrative may stand in the way of the development of further local energy transitions, as challenging elements of the process are downplayed to strengthen the narrative power of the story. Ethnographic stories about Samsø complicate the island’s transition narrative and add nuance to the Samsø story, highlighting its discrepancies and problematizing the effects of such well-crafted transition narratives. This tendency toward the ‘storification’ of transition processes is not restricted to Samsø; it is employed as a tactics by environmental organizations operating globally.  相似文献

IntroductionBased on the observation that autonomy is a fundamental concept in a world of work characterized by many transitions, this paper presents the construction and validation of a model and a scale of autonomy in career transitions.ObjectiveThe scale was developed to measure autonomy during adult career transitions.MethodA series of items was first produced following interviews with experts and employees. Three successive surveys involving 336, 314 and 450 participants made it possible, through item analysis and factor analysis, to reduce the number of items and to build a model composed of 14 items and 4 oblique factors.ResultsAfter confirmatory factor analysis, the data fit the model well and a study of external validity shows strong convergences with other measures of autonomy.ConclusionThe model and the measure of autonomy in career transition can be of great help in supporting employees. It makes it possible to identify the people who are most in difficulty and offers benchmarks to support and train organizations to modulate career paths and strengthen the acquisition of certain resources.  相似文献

The Interactive Systems Framework (ISF; Wandersman et al. in Am J Commu Psychol 41(3–4):171–181, 2008) was used to implement a kindergarten transition demonstration project collaboratively developed by elementary and early education providers, community‐based family and housing services, parents, and a University intermediary and technical assistance group. First person accounts from stakeholders at all levels provide a complementary and broad perspective on the project's implementation. The practice model blended existing research on kindergarten transition and parent involvement with feedback from stakeholders to create a community‐specific program designed to help all children make a smooth entry into kindergarten. During implementation, evidence‐based approaches needed to be adjusted to fit the specific needs of each community. Using the ISF as a guide, next steps and lessons learned include increasing leadership through a district‐wide plan that is still flexible within each school community, increasing information and supports to individual schools, and improving data collection for continuous program improvement.

ABSTRACT

In a rapidly changing world of work, little research exists on mid-career transitions. We investigated these using the open-systems approach of chaos theory as a guiding metaphor and conducted interviews with seven mid-career individuals chosen for their experience of a significant mid-career transition. Four common themes were identified through narrative analysis, where ‘false starts’ to a career were a common experience prior to finding a career ‘fit’. Career transitions, precipitated by a trigger state and/or event such as a period of disillusionment, were an important part of this ‘finding a fit’ process. Overall, career success outcomes were shaped by a combination of chaos elements: chance, unplanned events, and non-linearity of resultant outcomes. We discuss implications for future research and practice.  相似文献

The energetic driving force and resistance for shearing and cracking in metallic glasses (MGs) are quantitatively evaluated. A universal thermodynamic criterion is proposed for better understanding the intrinsic correlations between fracture toughness and Poisson’s ratio, the competitions between various deformation modes and the ductile-to-brittle transition in MGs and other materials. A new cooperation parameter δ is also introduced to depict quantitatively the relative propensity of shearing versus cracking. This work could provide insights into the long-standing issues of deformation mechanisms of glassy materials, and be helpful in searching for ductile and tough MGs.  相似文献

ABSTRACT

The basic mechanisms governing the process of cracking of single-layer brittle films have been extensively explored through both simulations and experiments. However, the role that an adhesive interlayer plays in the cracking of the overlying brittle film remains unclear. By performing three-point bending experiments, we observed that the insertion of a 100?nm thick Ti interlayer changed the cracking behaviour of TiN films from a continuous pattern to a discontinuous pattern. The slight change in the microstructure of the film and the increase in film thickness arising from the addition of the Ti interlayer are unlikely to cause the observed cracking morphology. The combination of the different interface between the Ti and the steel substrate and the fracture of the Ti interlayer are responsible for the transition in the TiN film cracking morphologies.  相似文献

ABSTRACT

The effect of heat treatments (solution and double aging) on friction and wear behaviour of Inconel 718 (IN718) alloy fabricated by selective laser melting (SLM) were studied. After heat treatment of solution and double aging, the friction and wear of the alloy have been improved. The worn surfaces of heat-treated IN718 alloy became smoother, and micro-ploughing became shallower. After solid solution hearting, a portion of the Laves phase ((Ni, Fe, Co)2(Nb, Ti, Mo)) dissolves into the matrix, after which the γ″ phase (Ni3Nb) andthe equilibrium phase of the δ phase (Ni3Nb) precipitates during double ageing. After solution and double aging, nano-scale γ′ (Ni3(Al, Ti)) and γ″ phases distribute homogeneously in the matrix, which improves the material hardness and wear resistance of the SLMed IN718 alloy.  相似文献

The present article aims to resolve the debate on the degree of benefit of processing tool or die steels by cryogenic treatment. This has been done by measuring transition loads for quenched and tempered die steel with and without cryogenic treatment. The wide range of reported degrees of improvement of wear resistance by cryotreatment is explained by the operative modes and mechanisms of sliding wear considering the wear rate ratio of conventionally treated to cryotreated steels on a two-dimensional map.  相似文献
