We investigated differences between field-study classrooms and traditional science classrooms in terms of the learning environment and students’ attitudes to science, as well as the differential effectiveness of field-study classrooms for students differing in sex and English proficiency. A modified version of selected scales from the What Is Happening In this Class? questionnaire was used to assess the learning environment, whereas students’ attitudes were assessed with a shortened version of a scale from the Test of Science Related Attitudes. A sample of 765 grade 5 students from 17 schools responded to the learning environment and attitude scales in terms of both their traditional science classrooms and classrooms at a field-study centre in Florida. Large effect sizes supported the effectiveness of the field-studies classroom in terms of both the learning environment and student attitudes. Relative to the home school science class, the field-study class was considerably more effective for students with limited English proficiency than for native English speakers.  相似文献

Despite the large volume of research and managerial literature on knowledge management, many practitioners seem to find it difficult to appreciate its added value for their managerial work. This paper aims to understand and elaborate the added value that knowledge management as a managerial approach can bring to the management of knowledge-intensive organizations. This study explores empirically the actual management practices of a knowledge-intensive organization and examines how knowledge-related phenomena are managed as embedded aspects of management. This paper makes a contribution to prior discussions concerning the relevance of knowledge management and the role of knowledge management as an embedded management practice. The findings of this study should be useful in explaining practitioners the nature, relevance and value of knowledge management.  相似文献

Hypertension is the most common cardiovascular risk factor. Lipoprotein(a) [Lp(a)], inflammation, oxidative stress and chronic kidney disease (CKD) exacerbate the response to tissue injury and acts as markers of the vascular disease, especially in glomerulosclerosis. We compared the clinical characteristics of 138 non-diabetes hypertensive women (ndHT) patients with 417 non-diabetes normotensive subjects and tested the association of hypertension with Lp(a), inflammation, CKD and oxidative stress by using multiple logistic regression. BP, BMI, waist circumference, creatinine, Lp(a), inflammation and malondialdehyde levels were significantly higher and CKD state in the ndHT patients (p < 0.05). Multiple logistic regression showed hypertension associated with increased Lp(a), inflammation, ORs and 95 % CIs were 2.52 (1.33, 4.80), 2.75 (1.44, 5.27) after adjusting for their covariates. Elevated serum Lp(a) and inflammation levels concomitants with increased oxidative stress and CKD were the major risk factors associated with hypertension and implications for the increased risk of HT and vascular disease.  相似文献

Der Beitrag diskutiert aus der Perspektive historischer Sozialisationsforschung gegenw?rtige Bilder vom Kind. Er skizziert die Grundzüge des romantischen Kindheitsmythos um 1800 und analysiert seine Kontinuit?ten in der P?dagogik um 1900 und an der Wende zum 21. Jahrhundert. Er zeigt, dass sowohl dem aktuellen Bestseller von Elschenbroich „Das Weltwissen der Siebenj?hrigen“ (2001), als auch Positionen der zeitgen?ssischen Kindheitsforschung durchaus romantische Elemente zugrunde liegen. Kritisch befragt werden in diesem Zusammenhang sowohl das Konzept der „Selbstsozialisation“, als auch die Annahme vom Verschwinden der Differenz zwischen Kindern und Erwachsenen. Der Beitrag endet mit einem Fazit, in dem Gründe für die Attraktivit?t des Kindheitsmythos aufgeführt sowie Forschungsfragen und -probleme er?rtert werden.  相似文献

Working in a country where the work culture is unknown to you—Oman in the Middle East—you are faced with yourself. What you need is a profound knowledge of the cultural, social and educational surroundings you are working in, which I did not have. Coming from a working‐class background, I was not unfamiliar with adjusting to cultural differences, but here I was the ‘advantaged’. I was the ‘expert’, with western knowledge: highly valued by some, feared by others. Living up to your expert role in unknown territory is a daunting process, as this article highlights.  相似文献

The reporting of intellectual capital (IC) in higher education institutions is of vital importance, mainly owing to the fact that knowledge is the main output and input in these institutions. Furthermore, the increasing social concern about establishing procedures of accountability and ensuring information transparency in public universities prompted us to consider the need to disclose information on their IC. In this study, we developed a questionnaire that was sent to members of the Social Councils of Spanish public universities in order to identify the intangible elements about which university stakeholders demand most information. It was also used to see which groups of universities have stakeholders who are more proactive to the disclosure of IC. Our results represent a starting point for public universities to identify the most commonly requested information about IC. Universities can then develop an IC report that fits their own characteristics and environment.  相似文献

The term absorptive capacity (AC) describes the process of utilising external knowledge. Although firms are becoming increasingly reliant on highly skilled freelancers as a source of external knowledge, the literature on AC has not incorporated this collaboration for freelancers. In this paper, we address this research deficit in two ways: First, we argue that the ability to collaborate effectively and efficiently with freelancers plays a crucial role in the process of absorbing external knowledge. Second, we argue that the example of freelancers challenges researchers to rethink the conceptualisation of organisational boundaries within the concept of AC. Our paper is based upon previous theoretical insights and exploratory empirical data from a research project on German IT freelancers. For the practice of knowledge management, our paper elaborates upon how organisations can enhance their AC by investing in practices and routines that contribute to successful collaboration with freelancers.  相似文献

A total of 112 Taiwanese junior college freshmen, assigned to an experimental group (N=59) and a control group (N=62), responded to the State-Trait Anxiety Inventory. After they had participated in a career education course the experimental group scores on state anxiety decreased. An analysis of variance of the state anxiety scores yielded two main significant effects (group and trait anxiety) and a two-way interaction was found with trait anxiety and group. There was clear support for the importance of the career education course. The results and implications for continuing research are discussed.  相似文献
