This paper examines the reasons why long‐serving teachers remain in the teaching profession. Interest in teacher retention has grown in recent years, both in the UK and internationally, due to concerns over teacher shortage. However, most research on retention has focused on why teachers leave; this paper aims to fill the gap in our understanding of the positive reasons why long‐serving teachers stay in the profession, and how these reasons change over time. We define ‘long‐serving teachers’ as teachers who have taught for 10 years and more. We draw on a subset of data from an existing, broader study (Menzies et al., 2015 ) on why teachers enter and stay in the profession. In this paper, we draw on questionnaire findings from over 900 teachers with 0 to over 30 years’ teaching experience, and interviews with 14 long‐serving teachers, to understand why long‐serving teachers enter and, more importantly for our purposes, stay in teaching. We find that teachers’ motivational patterns are highly complex and influenced by school‐level and policy contexts. Nonetheless, two prominent retention factors are identified: teachers’ perceived professional mastery and altruistic reasons. Perceived professional mastery is particularly important due to its mutually reinforcing analytic relationships with other reasons. We find that teachers’ identification with intrinsic, altruistic and perceived professional mastery reasons become stronger with years of experience, but in some cases, paradoxically, so does their identification with extrinsic reasons. From our evidence, we suggest policy implications for enhancing the retention of long‐serving teachers. 相似文献

The orthodox supply-side human capital theory (HCT) paradigm is inadequate for understanding and adjusting to labour market volatility in UK regional economies like Wales. This article explores the role of regional labour market intermediaries (LMIs) in matching supply (skills) and demand (job opportunities) in regional labour markets. Some LMIs emerge because the HCT paradigm is failing. One Welsh LMI, Shaping the Future (StF), is explored empirically using qualitative methods. StF mainly adopted HCT tenets, but with some emergent demand-side focus. Despite helping workers adjust to labour market shocks, LMIs are not equipped to fix the structural demand-side problem of finite quality job opportunities in deindustrialized regions that accentuate skill use. A broader ‘skill eco-system’ paradigm is required, emphasising the foundational economy. 相似文献

Teacher loss due to migration is a global phenomenon that impacts both developed and developing nations the world over. The aim of this study was to find out about the career plans of final-year South African student teachers. A group of final-year Bachelor of Education student teachers from a South African university responded to a questionnaire on intra- and intercontinental migration. The responses were analysed quantitatively and/or qualitatively. The findings showed that 79% of the students indicated that they would be teaching in South Africa, 8% were planning to teach in another country, while 8% were undecided. More than a third of the students (38%) said that they would like to teach in another country in five years’ time. Just more than a quarter of the students (27%) preferred Australia as a destination country. The student teachers’ most important motive to teach in a foreign country was the opportunity to travel, followed by earning a higher salary, and professional development. The student teachers indicated that their most important migration needs before leaving South Africa were information about health care, accommodation, and banking assistance. 相似文献

本文从决策者的有限理性角度,指出了集成供应链风险管理者的金字塔式心理账户结构;据此,构建了基于BFT和CDS、以多心理账户行为证券组合理论为核心的集成供应链避险模型;因有限理性符合风险管理者实际情景,决定了本研究较传统避险分析更为逼近集成供应链的现实避险决策。 相似文献

货币供应量作为我国货币政策中介目标的有效性分析 总被引:16,自引:0,他引:16
通过运用向量自回归(VAR)模型、脉冲响应函数(IRF)、方差分解分析等经济计量方法,本文对我国现行货币政策中介目标进行了实证分析并得出结论:货币供应量作为中介目标的有效性正不断降低,实际利率作为中介目标的实施效果好于货币供应量。本文认为,基础货币难以控制、货币乘数不稳定、货币流通速度不断下降和货币政策传导机制不完善等因素是产生上述实证结论的重要原因。最后,本文提出了相关建议。 相似文献

2019年底暴发的新冠肺炎疫情是一次重大的公共卫生事件,它对我国乃至世界的社会经济都将产生巨大而深远的影响。遗憾的是,这样的事件已不再是百年一遇,而是十年一遇或更短的时间,因此如何有效地应对大规模传染性疾病的暴发是人类社会面临的十分重要而迫切的问题。这次新冠肺炎疫情既是一个不幸,也是一个难得的学习机会。通过对疫情防控过程的回顾,以及对在该过程中所遇到的一些困难的梳理,发现很多问题最终都可以归结为供需矛盾的问题,而供给侧的挑战通常又都源于供应链的无序和混乱。文章结合现代供应链管理理论的一些基本原理,对疫情防控工作进行了分析并给出了建议,如建立全国联网传染病监测中心、国家防控战略物资安全库存、国家突发事件应急管理指挥中心等。另外,疫后经济重建也至关重要,因此还从供应链思维的角度,分析了新冠肺炎疫情的行业影响,以及企业复工复产过程中应该注意的事项。 相似文献
