Stimulators and barriers towards social innovations in public libraries: Qualitative research study     

Ladislava Zbiejczuk Suchá  Eliška Bartošová  Roman Novotný  Jiřina Bělehradová Svitáková  Tomáš Štefek  Eva Víchová 《Library & information science research》2021,43(1):101068

Public libraries have a huge potential to be creators and facilitators of social innovation in communities and society. Qualitative research based on interviews with 27 librarians showed that social innovation in libraries can take the form of educational and cultural activities, leisure and networking activities and social support services. The main goal of the research was to find out what factors support and make these innovations difficult in public libraries. A four-layer model of barriers and stimulators for social innovation is presented, which includes structural, local, organizational and personnel levels. The model could serve to inform librarians, their stakeholders and governments about all levels of barriers and stimulators connected to innovation of library services and social re-positioning of public libraries in the future.  相似文献

Competencies in Geriatric Nursing: Empirical Evidence from a Computer-Based Large-Scale Assessment Calibration Study     

Roman Kaspar  Ottmar Döring  Eveline Wittmann  Johannes Hartig  Ulrike Weyland  Annette Nauerth  Michaela Möllers  Simone Rechenbach  Julia Simon  Iberé Worofka 《Vocations and Learning》2016,9(2):185-206

Valid and reliable standardized assessment of nursing competencies is needed to monitor the quality of vocational education and training (VET) in nursing and evaluate learning outcomes for care work trainees with increasingly heterogeneous learning backgrounds. To date, however, the modeling of professional competencies has not yet evolved into procedures that would meet large-scale assessment (LSA) standards in VET. To empirically test a proposed structural model for client-directed nursing competence and to estimate psychometric properties of a newly developed video- and computer-based test (CBT) to inform subsequent LSA in nursing VET, 402 final-year nursing students from 24 German schools responded to a 77 item CBT. Multi-dimensional IRT modeling was employed to test the subdomain structure and estimate students’ competencies in geriatric nursing. The standardized CBT measures nursing students’ client-directed care competence with acceptable precision (WLE?=?0.76) and does so across the whole range of observed proficiency levels. Structural validity was supported by substantive contributions of test items from all proposed process-oriented subdomains, practice field scenarios, as well as items with and without reference to emotional demands. However, it was not possible to empirically separate the diagnostic, practical or communicative subdomains, probably reflecting parallel, recursive and hierarchical care processes in complex care situations. On average, students in our sample attained 45 % of the maximum test score so it is a demanding assessment of nursing competence. An extensively piloted, valid and reliable CBT is suggested to assess nursing students’ client-directed care competencies at the end of the third year of the VET program.  相似文献   

Dynamics of a periodically driven chain of coupled nonlinear oscillators     

Paweł Fritzkowski  Roman Starosta  Grażyna Sypniewska-Kamińska  Jan Awrejcewicz 《浙江大学学报(A卷英文版)》2017,18(7):497-510

A 1D chain of coupled oscillators is considered, including the Duffing-type nonlinearity, viscous damping, and kinematic harmonic excitation. The equations of motion are presented in a non-dimensional form. The approximate equations for the vibrational amplitudes and phases are derived by means of the classical averaging method. A simple analysis of the resulting equations allows one to determine the conditions for the two basic synchronous steady-states of the system: the in-phase and anti-phase motions. The relations between the required excitation frequency and the natural frequencies of the abbreviated (linear) system are discussed. The validity of these predictions is examined by a series of numerical experiments. The effect of the model parameters on the rate of synchronization is analyzed. For the purpose of systematic numerical studies, the cross-correlation of time-series is used as a measure of the phase adjustment between particular oscillators. Finally, some essential issues that arise in case of the mechanical system with dry friction are indicated.  相似文献

Feedback in educational communication in Czech secondary schools     

Klára ?e?ová  Roman ?va?í?ek 《Educational Assessment, Evaluation and Accountability》2012,24(3):239-261

This paper introduces an empirical study that examines how teachers evaluate pupils?? responses. The study draws on research undertaken at four secondary schools in the Czech Republic. It transpires that feedback has a stable position in the structure of communication; however, it is used only to verify pupils?? responses and not to elaborate them. An important feature of feedback is its implicitness and near-zero content value resulting from the teachers?? preferences to avoid explicit evaluative comments. This type of feedback is not in accordance with the concepts of dialogical education that currently dominate the field of the theory of educational communication.  相似文献   

Assessing the Correlates of Over- and Underrating of Academic Competence: A Conceptual Clarification and a Methodological Proposal   总被引：1，自引：0，他引：1  

Avi Assor  Joseph Tzelgov  Roman Thein  Barbara C. Ilardi  James P. Connell 《Child development》1990,61(6):2085-2097

The present article addresses 3 issues pertaining to the conceptualization and assessment of the effects of over- and underrating academic competence. First, it is shown that it is impossible to separate the effects of over- and underrating from the effects of both perceived and actual competence. Second, it is shown that the method used by Connell and Ilardi in a previous article to assess the effect of net overversus underrating is of questionable validity. Finally, a new definition and method for assessing the effects of over- and underrating is presented. The new method was applied to Connell and Ilardi's data to retest the hypothesis that overrating is associated with more problematic psychological profiles than accuracy and underrating. Results did not generally support the hypothesis, but did show that the correlates of over- and underrating vary as a function of both extremity of over- or underrating and the level of children's actual competence.  相似文献   

Employers’ skill preferences across Europe: between cognitive and non-cognitive skills     

Lucia Mýtna Kureková  Miroslav Beblavý  Corina Haita  Anna-Elisabeth Thum 《Journal of Education & Work》2016,29(6):662-687

This article analyses online job advertisements to identify skills that are demanded in selected low- and medium-skilled occupations. We explore data from the publicly administered cross-European EURES job search portal and quantify the different cognitive and non-cognitive skills requested by employers in small European economies. While we find that the service sector demands non-cognitive skills more than other types of occupation, the skill-mix demanded is very diverse across countries, implying that other domestic factors shape how demand is formulated. Our work shows that online portals can become a useful source for studying employers’ demand at the micro-level to inform employment, education and training policies.  相似文献   

Place-based education from three perspectives     

Jan Cincera  Barbora Valesova  Sarka Krepelkova  Petra Simonova  Roman Kroufek 《Environmental Education Research》2019,25(10):1510-1523

Abstract

This article examines the perception of the Czech place-based education program School for Sustainable Development from the perspectives of the participating students, teachers, and representatives of the local municipalities. The study is based on an analysis of paired or group interviews with 47 students, 7 teachers, and 6 representatives. The findings show that while the teachers perceived the process of the students’ involvement in planning and conducting a community-based project as highly participative, the students’ opportunities to shape the process through making their own decisions were rather limited and the teachers kept control over important parts of the process to themselves. While the cooperation of the schools with their respective municipalities was appreciated by most of the respondents, several barriers have been identified. Participation in the project has likely increased the teachers’ self-effectiveness, developed the students’ interpersonal competence, and improved the atmosphere at the schools involved.
