Library employees hold perceptions about the fairness of the outcomes, processes, and interpersonal treatment in their workplaces. When employees feel the workplace is fair they are more likely to feel commitment to the organization, perform in-role and extra-role tasks, and experience job satisfaction. When employees perceive injustice in the workplace, research points to negative outcomes such as withholding work or even sabotage. To understand the antecedents of organizational justice, researchers carried out a national survey of librarians to compare the predictive power of perceived organizational support, job autonomy, job feedback, and job stress. Results indicate that increasing librarians' perceptions of organizational support and their autonomy, and providing meaningful and timely job feedback can increase overall perceptions of justice. Managers can enhance a climate of justice in their workplaces by developing strategies that target organization support, autonomy, and feedback to reduce a sense of injustice between and among employees.  相似文献

To date, the concept of English for Specific Purposes has brought about a great impact on English language learning across various disciplines, including those in science education. Hence, this review paper aimed to address current English language learning in the science disciplines through the practice of computer-assisted language learning to identify the use of learning technologies in science-based literacy. In the literature review, the researchers found that science-based literacy instruction shares many pedagogical aims with English language teaching in terms of reading, writing, listening and speaking, allowing it to be classified as English for Scientific Purposes (EScP). To answer the research questions, the researchers conducted the survey by extracting related articles and teaching examples from the Web of Science. In the search procedure, the researchers used the keywords science OR scientific AND technolog* OR comput* in ten selected journals of social science citation index. Only articles which are specified as journal articles rather than other document types were included. After compiling the corpora, the researchers compared the trends, methodologies and results of EScP instruction in science education. The implications of this study include the opportunities, advantages and challenges for EScP instruction in science education to further develop better educational approaches, adopt new technologies, as well as offer some directions for researchers to conduct future studies.  相似文献

The social, economic, and cultural changes that occurred in Russia following the collapse of the Soviet Union have combine to impose sever damage on the population, and not least on Russia's young people. The provision of new forms of social and economic support are needed, as well as new youth programs, if further damage is to avoided.  相似文献

The externality‐tangibility model of human performance is a human performance technology (HPT) model that categorizes nine all‐inclusive elements of HPT into families of elements that can be external or internal to a performer and tangible or intangible. This third of three installments looks at the two factors that are external to a performer and are intangible: management and leadership. Applying the externality‐tangibility model consistently entails a six‐step process. There are limits to the externality‐tangibility model because it is focused on human performance and not on other factors of organization performance.  相似文献

From all over the world there have been calls from governmental institutions to address a shortage of high quality teachers. As changing jobs generates new experiences, job mobility could be a way for teachers to adhere to the government’s call to develop themselves into the teaching force needed. The research question of this study was: How do the experience with mobility and the attitude towards mobility of Dutch secondary school teachers shape their intentions to be mobile? A secondary analysis was conducted on data collected among 1261 respondents. Attitudes towards mobility were found to be linked to past experience with mobility and there is a strong relationship between the attitude towards mobility and the intention to be mobile. The control variables age, experience in teaching, and type of employment seem to have an effect as well. Implications for the teacher shortage issue are discussed.  相似文献

In this article, we, colegas/colleagues of color, explore the ways in which the literary and artistic contributions of Gloria Anzaldúa, Octavia Butler, and Frida Kahlo have inspired, nurtured, and profoundly influenced our personal and professional lives as academics. We underscore the importance of mentoring for women of color in academe and educational leadership, particularly the psychosocial functions associated with informal mentoring. Further, we discuss how the lives and contributions of our “mentors” impacted our scholarly journeys, framed by third-wave and decolonial woman-of-color-feminism. In this article, we offer an alternative consideration for women of color in search of suitable mentors, concludes by sharing the lessons we learned from the artists. Thinking about mentoring from the position of alterity adds to the general mentoring discourse and serves to inspire women to consider alternatives when seeking mentorship to reach academic and professional goals.  相似文献

Currently educational research literature demonstrates wide discussion and endorsement of ‘distributed’ leadership while concurrently traditional, hegemonic forms prevail in practice. This article investigates understandings about educational leadership held by Australian school principals. The article describes the contradictory conceptions about educational leadership currently in circulation. It interrogates underlying assumptions and questions how both hegemonic and newer leadership conceptions and assumptions serve educational leaders. Data from principals around the country and across education systems reinforced the predominance of un-theorised or under-theorised notions about leadership, with similar assumptions found in important policy artefacts and practices. This article emerges from interviews with 100 principals focusing on their professional learning needs, which revealed interesting ideas, issues and dilemmas concerning ‘leadership’. It fills a gap in research on distributed leadership by exploring contradictions inherent in policy, practice and understandings in this area. The article is structured into four sections. First, extant literature on this topic and the research are explained. Second, the article focuses on principals' conceptions about leadership and those inherent within important policy and practical artefacts. A discussion of the findings focuses on the discrepancy between theory and policy endorsement and the views of practitioners. Finally, the article canvasses the implications of the research.  相似文献
