Background: Students on health and social care degree programmes spend 50% of their time on practice placements. Because of the diversity of settings and the need to evidence their work, it is vital to understand the information and resource needs of placement students. Objectives: The aim of this investigation was to understand the needs of placement students in terms of accessing resources whilst they are in the field in order to inform a guide to meet these needs. Methods: Focus groups were conducted with students on midwifery, social work and post‐registration health professions degree programmes on three different sites across the region. Data were analysed using Thematic Content Analysis. Results: Three themes emerged from the data: inequality, user education needs and students’ solutions and strategies. Conclusions: It is essential to speak to placement students in order to understand their needs in terms of accessing and using library resources. The timing and content of information skills training is key to meeting student needs while on placement. 相似文献

This article analyses attitudes of academic authors toward open access (OA) and the frequency of choosing OA publication venues. The research looks particularly at differences between authors based in countries with a gross domestic product per capita less or greater than US$18,000 (called periphery and core countries, respectively). The data were obtained with an online survey sent to 107,296 scholars listed on the mailing lists belonging to De Gruyter Open from December 2015 to January 2016. A total of 1,012 responses were received. Authors from the periphery countries publish their articles in gold OA more often and they also pay OA publication fees equally often as those based in the core countries. The reasons for that are complex, involving both their preference to publish in OA and the composition of the publishing market in the periphery. 相似文献

In this study, the fibers of invasive species Agave americana L. and Ricinus communis L. were successfully used for the first time as new sources to produce cytocompatible and highly crystalline cellulose nanofibers. Cellulose nanofibers were obtained by two methods, based on either alkaline or acid hydrolysis. The morphology, chemical composition, and crystallinity of the obtained materials were characterized by scanning electron microscopy(SEM) together with energy-dispersive X-ray spectroscopy(EDX), dynamic light scattering(DLS), X-ray diffraction(XRD), and Fourier transform infrared(FTIR)spectroscopy. The crystallinity indexes(CIs) of the cellulose nanofibers extracted from A. americana and R. communis were very high(94.1% and 92.7%, respectively). Biological studies evaluating the cytotoxic effects of the prepared cellulose nanofibers on human embryonic kidney 293 T(HEK293 T) cells were also performed. The nanofibers obtained using the two different extraction methods were all shown to be cytocompatible in the concentration range assayed(i.e., 0-500 μg/mL). Our results showed that the nanocellulose extracted from A. americana and R. communis fibers has high potential as a new renewable green source of highly crystalline cellulose-based cytocompatible nanomaterials for biomedical applications. 相似文献

Promoting Vocational Development: Methods of Intervention
and Techniques Used in the Italian Context
Laura?NotaEmail author Salvatore?Soresi Scott?H.?Solberg Lea?Ferrari 《International Journal for Educational and Vocational Guidance》2005,5(3):271-279
This article describes a Master Educator Series designed to help educators in Italy design and implement comprehensive vocational guidance curriculum. In this “Master Educator” training, a variety of vocational development models and theories are presented. The goal is to provide a broad range of skills in assessment and intervention strategies to prepare educators for developing the curriculum that best fits their unique context. Five curriculum examples are described. Each of these interventions is built around a vocational development topic, including: providing individualized feedback, improving social relationships and connections, using written exercises, and providing mastery and vicarious experiences. 相似文献

Asthma is a pervasive inflammatory disorder of the bronchial airways that causes the normal functioning of the airways to become overreactive. This disorder affects approximately 8 million children in schools per year and accounts for a significant amount of absences. Researchers have speculated that pharmacological interventions are alone insufficient or overaggressive in treating asthma, and numerous studies have demonstrated a connection between emotions and asthma. It has therefore been suggested that psychological interventions may be appropriate for this population. One such intervention, relaxation and guided imagery (RGI), that incorporates mental representations as well as the senses in a process of relaxing all the parts of the body has been shown to be effective with children with asthma. The current study served as a replication and extension of this previous research. The purpose of the investigation was to examine the effectiveness of RGI with an elementary school sample as well as determine the overall improvement in happiness, anxiety, and quality of life of the participants. Results demonstrated that RGI significantly improved the lung functioning of 3 out of 4 participants in the study. Furthermore, overall happiness improved for 1 participant in the study, state anxiety decreased for 2 of the 4 participants, and trait anxiety decreased for all 4 participants. © 2005 Wiley Periodicals, Inc.

The main aim of this research is to examine the basic features of student teachers’ professional beliefs about the teacher’s role in relation to teaching mainstream pupils and pupils with developmental disabilities. The starting assumption of this analysis is that teacher professional development is largely dependent upon teachers’ beliefs about various facets of their professional work. These concepts strongly influence the way that teachers teach and the way that they develop as teachers. The participants in the research are 314 student teachers at the Faculty of Teacher Education of the University of Zagreb who are being prepared to teach in lower grades of primary school. The beliefs were explored using a metaphor technique derived from cognitive theory of metaphor. The differences between beliefs about the perceived teacher role in general, and the perceived teacher role in the education of pupils with developmental disabilities were analysed. The results indicate that the dominant belief about the teacher’s role in teaching mainstream pupils is of the teacher as a transmitter of knowledge, while the findings regarding the dominant belief about the teacher’s role in teaching pupils with developmental difficulties appeared to be self-cantered orientation. No differences were found between student teachers at different study levels. The findings are discussed in the light of the curriculum of initial teacher education. 相似文献
