The governments of cities have to make important decisions on the future of their communities. In the past, the vision, objectives, and goals of cities have been determined mainly by considering tangible assets as the main factors of a city's prosperity. However, in the knowledge economy, the role of intangible assets in wealth creation has become fundamental. As a result, a framework of intangible assets that allows navigation from the present reality to the future vision has become an urgent need for all cities. The paper has two well-defined parts. In the first part, it develops a specific methodology and framework for measuring and managing the intellectual capital of cities. In the second part, the study deals with the practical application of this model of intellectual capital in cities with the specific case of the city of Mataró, providing some details of the first cities’ intellectual capital report.  相似文献

This paper presents the results of an inductive, interpretive analysis of the perspectives of 42 Canadian high school distance education (DE) teachers on asynchronous and synchronous online teaching. The paper includes a conceptual overview of the affordances and constraints of each form of teaching. Findings provided insight into the following aspects of asynchronous and synchronous online teaching: degree of use; the tools used; the contexts in which each occur; students' preferences; and limitations. Pedagogy emerged as more important than media for both asynchronous and synchronous online teaching. Synchronous online teaching relied on teacher‐ rather than student‐centred approaches. Asynchronous online teaching provided support for self‐paced, highly independent forms of secondary DE supplemented by synchronous online teaching for answering questions and troubleshooting.  相似文献

Health literacy has firmly established the links between literacy skills and health outcomes and is subsequently considered a key strategy for improving the health of disadvantaged populations and addressing social inequality. However, current research findings for improving health literacy have primarily focused on adults and actions within health and health care settings. Implementation studies outside the health sector are scarce. This study, a subset of the INCLUD-ED community- based project on social inclusion, reports on successful community-based approaches to health literacy. This article focuses on two schools that take advantage of the cultural intelligence of their students' family members, allowing them to make health literacy programmes more effective and useful for the participants. In addition, family involvement in educational activities addressed to children, including health programmes, has been found to improve the health literacy of the participating adults and their use of healthcare services. Findings indicate that schools in Europe can play a key role in breaking the cycle of health inequalities by promoting health literacy through education.  相似文献

This article examines how students from the ‘loser’ sections of the middle class dealt with the game of secondary schooling in a ‘good’ state school in the city of Buenos Aires (Argentina). It engages with Bourdieu’s theory of social practice and, in particular, with its concepts of game, habitus and cultural capital. It argues that middle‐class students embody a school habitus, which I call zafar. Zafar (a Spanish slang word) refers to students’ dispositions, practices and strategies towards social and educational demands of teachers and their school. Zafar propels middle‐class students to be just ‘good enough’ students, and promote an instrumental approach to schooling and learning. Although this paper offers an account within which the reproduction of relative educational advantage of a group of middle‐class students takes place, it also poses questions about their future educational and occupational opportunities.  相似文献

Objective

Psychological maltreatment (PM) is the most prevalent form of child abuse, and is the core component of most of what is considered as child maltreatment. The aim of this work was to explore differential adverse outcomes of the different types of PM in the mental health and functioning of children living in homes in which they are exposed to intimate partner violence (IPV).

Method

Participants were 168 children, aged between 4 and 17, whose mothers experienced IPV. They were assessed using different measures of psychopathology and functioning: Diagnostic Interview for Children and Adolescents-IV, Child Behavior Checklists and Child and Adolescent Functioning Assessment Scale. Furthermore, IPV was assessed with the Schedule for Assessment of Intimate Partner Violence Exposure in Children and the Index of Spouse Abuse. Statistical analyses were carried out with regression models adjusted by means of Generalized Estimating Equations.

Results

Spurning was the PM subtype with the greatest global effect on the children, as it was significantly associated with internalizing and externalizing problems. Denying emotional responsiveness specifically increased the risk of internalizing psychopathology and impairment in the emotional area. Terrorizing was not significantly associated with a greater number of negative outcomes in children's psychopathology or functioning in this population.

Implications

The results suggest the importance of taking PM types into account in order to fully understand the problems of children exposed to IPV at home, and for the design of effective treatment and prevention programs.  相似文献

This paper addresses the flocking motion problem for swarms of agents with two restrictions: limited communication/detection ranges and different input constraints. In this problem, the distance between pairs of agents determines if a communication/detection link exists among them, while each agent has a different control action bound. We use the notion of proximity graph to model communication/detection between agents and provide distributed controllers designed for leaderless and leader-followers flocking motion scenarios. Our proposed designs preserve the connectivity of the proximity graph while the control effort satisfies the bound of each particular agent. Unlike previous results, our protocols take advantage of the group’s input heterogeneity to use agents with a greater capacity to compensate for neighbors that are less capable of meeting the group’s requirements. Additionally, our designs are based only on local state errors and are robust to non-modeled edge failures. To illustrate the effectiveness of our proposal, we use numerical simulations of different flocking scenarios.  相似文献

In 2008, the type of document “proceedings paper” (PP) was assigned in the WoS database to journal articles which were initially presented at a conference and later adapted for publication in a journal. Since the use of two different labels (“article” and “proceedings paper”) might lead to infer differences in their relevance and/or quality, this paper presents a comparative study of standard journal articles and PP in journals to explore potential differences between them. The study focuses on the Library and Information Science field in the Web of Science database and covers the 1990–2008 period. PP approximately account for 9% of the total number of articles in this field, two-thirds of which are published in monographic issues devoted to conferences, which tend to be concentrated in specific journals. Proceedings papers emerge as an heterogeneous set comprising PP in ordinary issues, similar to standard articles in structure and impact of research; and PP in monographic issues, which seem to be less comprehensive and tend to receive less citations. Faster publication of PP in monographic than in ordinary issues may conceal differences in the review process undergone by either type of paper. The main implications of these results for authors, bibliometricians, journal editors and research evaluators are pointed out.  相似文献
