Cyberbullying victimization research on individual and familial correlates is scarce in Spain. By building upon previous studies, this research examines the role of Internet usage and parental mediation in online victimization. Spanish children from rural public schools (10–12 years; n?=?1068) completed a self-report questionnaire which measured being cyberbullied, Internet use and parental mediation strategies. Logistic regression analyses examined the association among cyberbullying victimization, online activities, intensity and purposes of online communication, and restricting, evaluating and co-using parental mediation. The results show that Internet use, specifically online communication, increases the likelihood of cyberbullying victimization. Conversely, monitoring software installed on the computer, joint creation of rules regarding the time spent online and personal information shared help lessen the likelihood of online victimization. The results are examined in the light of previous research, while implications for practice and future research are considered. 相似文献

Abstract Popular filmic and literary stereotypes of teachers from Brodie and Chips to Keating and Schneebly have not only reflected a public desire for radically innovative and perverse teaching practices, but also created those paradigms in ways that are not always readily identifiable or traceable. This article seeks to analyse tensions between traditional institutional protocols and contemporary populist opinion on the role of the effective teacher. In doing so, the article takes Peter Weir’s Dead Poets Society (1989) as a primary example of those tensions and argues for a perverse ‘foolosophical’ view of pedagogical performance and a new appreciation for the necessity of ignorance in the classroom. Since ignorance and understanding are not taken as unambiguous antonyms, the article proposes that effective teaching and learning occur most effectively in the interstices between humility and hospitality. 相似文献

In our current age of rapid social, economic and technological change, including urbanisation, globalisation and information overload, human beings are more than ever seeking orientation and meaning. In this situation, education is the potential key to individual empowerment, cultural prosperity, social cohesion and economic development. Arguing for the learning city as the location where a real learning culture is being developed, the author of this article discusses the need to build a new citizenship involving democratic, social, egalitarian (gender-balanced), intercultural and environmental dimensions. Based on a new humanism, this new citizenship should be designed to overcome the exclusion of many in the interests of a few and enable a meaning-friendly evolution in our social institutions. Thus the means of knowing, understanding and being in the world of knowledge, which are essential for liberating the human mind, can be provided to everyone. 相似文献

Performance equivalency between computer‐based and traditional pen‐and‐paper assessment: A case study in clinical anatomy 下载免费PDF全文
Bruno Guimarães José Ribeiro Bernardo Cruz André Ferreira Hélio Alves Ricardo Cruz‐Correia Maria Dulce Madeira Maria Amélia Ferreira 《Anatomical sciences education》2018,11(2):124-136
The time, material, and staff‐consuming nature of anatomy's traditional pen‐and‐paper assessment system, the increase in the number of students enrolling in medical schools and the ever‐escalating workload of academic staff have made the use of computer‐based assessment (CBA) an attractive proposition. To understand the impact of such shift in the assessment method, an experimental study evaluating its effect on students’ performance was designed. Additionally, students’ opinions toward CBA were gathered. Second‐year medical students attending a Clinical Anatomy course were randomized by clusters in two groups. The pen‐and‐paper group attended two sessions, each consisting of a traditional sectional anatomy steeplechase followed by a theoretical examination, while the computer group was involved in two similar sessions conducted in a computerized environment. At the end of each of the computer sessions, students in this group filled an anonymous questionnaire. In the first session, pen‐and‐paper group students scored significantly better than computer‐group students in both the steeplechase (mean ± standard deviation: 66.00 ± 14.15% vs. 43.50 ± 19.10%; P < 0.001) and the theoretical examination (52.50 ± 12.70% vs. 39.00 ± 21.10%; P < 0.001). In the second session, no statistically significant differences were found for both the steeplechase (59.50 ± 17.30% vs. 54.50 ± 17.00%; P = 0.085) and the theoretical examination (57.50 ± 13.70% vs. 54.00 ± 14.30%; P = 0.161). Besides, an intersession improvement in students’ perceptions toward CBA was registered. These results suggest that, after a familiarization period, CBA might be a performance equivalent and student accepted alternative to clinical anatomy pen‐and‐paper theoretical and practical examinations.

The expansion of private sectors of higher education has usually been regarded as a factor of diversification in higher education
systems. Some of this differentiation has been found to arise from the affiliation of private institutions with organizations
outside the field of higher education. This article reports the results of a study of this form of interorganizational relationship
in private universities in Chile. Cases include universities founded or sponsored by religious, business and military organizations.
A typology of private universities is proposed, on the basis of the forms affiliation (or its absence), was observed to take
in the cases examined. Weak and strong forms of affiliation are described, and affiliated universities are compared to “proprietary”
universities, i.e., those owned by individuals who govern them from their positions in the board of directors, and “independent”
universities, in which governance lies with internal – academic or administrative – constituents. Albeit derived from the
case of Chile, the typology could be applied to the analysis of private higher education in other national systems. The second
part of the article seeks to ascertain whether affiliation operates as a source of differentiation in Chilean private higher
education. Results show that, compared to the other types of private universities, the affiliated ones possess distinctive
mission statements and declarations of principles, consistent with the orientations of their sponsor institutions, they tend
to be smaller, and to have more full-time and better qualified faculty. Some receive financial support from their sponsor
organization or its members. Distinctiveness was not found in indicators of prestige and student selectivity, nor in tuition
levels, program offerings, curriculum design, the weight of research and graduate programs in their functions, student socioeconomic
profile, and faculty involvement in governance. This is not to say that there are no differences in these dimensions among
private universities: much diversity exists, but most of it cuts across all categories of interest for our study. Overall,
affiliation does not appear to be a strong factor behind the diversification that exists in the Chilean private university
sector. 相似文献

In distributed and cooperative systems, the network structure is determinant to the success of the strategy adopted to solve complex tasks. Those systems are primarily governed by consensus protocols whose convergence is intrinsically dependent on the network topology. Most of the consensus algorithms deal with continuous values and perform average-based strategies to reach cohesion over the exchanged information. However, many problems demand distributed consensus over countable values, that cannot be handled by traditional protocols. In such a context, this work presents an approach based on semidefinite programming to design the optimal weights of a network adjacency matrix, in order to control the convergence of a distributed random consensus protocol for variables at the discrete-space domain, based on the voter model. As a second contribution, this work uses Markov theory and the biological inspiration of epidemics to find out a dynamical spreading model that can predict the information diffusion over this discrete consensus protocol. Also, convergence properties and equilibrium points of the proposed model are presented regarding the network topology. Finally, extensive numerical simulations evaluate the effectiveness of the proposed consensus algorithm, its spreading model, and the approach for optimal weight design. 相似文献

Reduction of water evaporation in polymerase chain reaction microfluidic devices based on oscillating-flow 总被引:1,自引:0,他引:1

Producing polymeric or hybrid microfluidic devices operating at high temperatures with reduced or no water evaporation is a challenge for many on-chip applications including polymerase chain reaction (PCR). We study sample evaporation in polymeric and hybrid devices, realized by glass microchannels for avoiding water diffusion toward the elastomer used for chip fabrication. The method dramatically reduces water evaporation in PCR devices that are found to exhibit optimal stability and effective operation under oscillating-flow. This approach maintains the flexibility, ease of fabrication, and low cost of disposable chips, and can be extended to other high-temperature microfluidic biochemical reactors. 相似文献

ABSTRACTPreventive conservation, with its origins grounded in the material fabric of cultural material, is in a period of transformation, with numerous practitioners, in and outside of the field of conservation, considering its broader and holistic objectives. The conventional tools for the assertion of preventive conservation principles, namely the assessment and management of risks to cultural material from the ‘ten agents of deterioration’, have a central focus on the primacy of physical materials and degradation, with less clear relationships with people, place, and time in their modelling. With a case study focus on collections in the Philippines, this paper argues for a practice of preventive conservation that incorporates a balanced assessment and broader thinking around the contexts of objects, people, place, and time. The case studies of ecclesiastical Church collections, and museum environments in the Philippines, demonstrate how the interdependency of objects, people, place and time forms a holistic and conceptual preventive conservation framework. Through a cyclic renegotiation of these four parameters, this paper speculates on the gaps and opportunities for an inclusive view of preventive conservation that is current and more sustainable. 相似文献
