Over the last few decades climate change has been gaining importance in international scientific and political debates. However, the social sciences, especially in Latin America, have only lately become interested in the subject and their approach is still vague. Scientific understanding of global environmental change and the process of designing public policies to face them are characterized by their complexity as well as by epistemic and normative uncertainties. This makes it necessary to problematize the way in which research efforts understand ‘the social’ of climate change. How do ‘the climate’ and ‘the social’ interpenetrate as scientific objects? What does the resulting field look like? Is the combination capable of promoting reflexivity and collaboration on the issue, or does it merely become dispersed with diffuse boundaries? Our paper seeks to answer these and other related questions using Chile as a case study and examining peer-reviewed scientific research on the topic. By combining in-depth qualitative content analysis of each paper with a statistical meta-analysis, we were able to: characterize the key content and forms of such literature; identify divisions and patterns within it; and, discuss some factors and trends that may help explain these. We conclude that the literature displays two competing trends: while it is inclined to become fragmented beyond the scope of the ‘mitigation’ black box, it also tends to cluster along the lines of methodological distinctions traditionally contested within the social sciences. This, in turn, highlights the persistence of disciplinary divisions within an allegedly interdisciplinary field.

In recent years the methodology of engineering education has been changing and many projects deal with improving the educational software. This paper reports on the virtual laboratory, a virtual environment applied to experimental analysis. The goals of the virtual laboratory are to introduce the laboratory environment to the student entering this world, so different from the typical theoretical lectures, for the first time, and to overcome the above-mentioned drawbacks. It should be mentioned that the virtual laboratory is not meant to replace highly enriching, practical experience, but rather is meant to train the individual, in order to improve his/her performance in later actual practice. The virtual laboratory experience starts with the study of strain measurements, an engineering technique widely used to measure deformations, strains, mechanical properties of materials and other variables which are used to analyse many problems.The strain measurement virtual laboratory is meant to offer the possibility of simulating experiences, undergone in a real laboratory, through the Internet. The student is expected to familiarize him/herself with the techniques, procedures, devices and theories in the laboratory environment. 相似文献

Accountability and quality assurance have become central discourses in higher education policy throughout the world. However, accountability and quality assurance involve power and control. Practices and ideas about quality developed in the Global North are spreading rapidly across the Global South, leading to increased uniformity in the approaches to quality assurance. Given the significant asymmetries that divide the Global North and Global South, this article maps interdiscursive relations among key texts that influence policy development on international quality in higher education, and explores the applicability of colonial discourse as a perspective for understanding this increasing international convergence. 相似文献

This study examined the associations among maternal depression, mothers’ emotional and material investment in their child, and children's cognitive functioning. Middle-class Chilean mothers and children (N = 875; 52% males) were studied when children were 1, 5, 10, and 16 years (1991–2007). Results indicated that highly depressed mothers provided less emotional and material support to their child across all ages, which related to children's lower IQ. Children with lower mental abilities at age 1 received less learning-material support at age 5, which led to mothers’ higher depression at child age 10. Mothers’ low support was more strongly linked to maternal depression as children got older. Findings elucidate the dynamic and enduring effects of depression on mothers’ parenting and children's development. 相似文献

We present IntoNews, a system to match online news articles with spoken news from a television newscasts represented by closed captions. We formalize the news matching problem as two independent tasks: closed captions segmentation and news retrieval. The system segments closed captions by using a windowing scheme: sliding or tumbling window. Next, it uses each segment to build a query by extracting representative terms. The query is used to retrieve previously indexed news articles from a search engine. To detect when a new article should be surfaced, the system compares the set of retrieved articles with the previously retrieved one. The intuition is that if the difference between these sets is large enough, it is likely that the topic of the newscast currently on air has changed and a new article should be displayed to the user. In order to evaluate IntoNews, we build a test collection using data coming from a second screen application and a major online news aggregator. The dataset is manually segmented and annotated by expert assessors, and used as our ground truth. It is freely available for download through the Webscope program.1 Our evaluation is based on a set of novel time-relevance metrics that take into account three different aspects of the problem at hand: precision, timeliness and coverage. We compare our algorithms against the best method previously proposed in literature for this problem. Experiments show the trade-offs involved among precision, timeliness and coverage of the airing news. Our best method is four times more accurate than the baseline. 相似文献

The present study was designed to examine acculturative changes, and their effects on mental health and family functioning, in recent‐immigrant Hispanic adolescents. A sample of 302 Hispanic adolescents was assessed five times over a 2½‐year period. Participants completed measures of Hispanic and U.S. practices, collectivist and individualist values, and ethnic and U.S. identity at each time point. Baseline and Time 5 levels of mental health and family functioning were also assessed. Latent class growth analyses produced two‐class solutions for practices, values, and identifications. Adolescents who increased over time in practices and values reported the most adaptive mental health and family functioning. Adolescents who did not change in any acculturation domain reported the least favorable mental health and family functioning. 相似文献

No basta regalar la caña para formar un pescador ni el lápiz para enseñar a escribir. La introducción de la tecnología audiovisual, basada en medios más aparatosos que la lectoescritura, ha podido confundir medios y sistemas de representación, instrumento y código. La información precisa y de primera mano sobre el proyecto Mercurio del M.E.C. que se da en este artículo define un programa que va mucho más allá de los tradicionales objetivos de enseñar a utilizar los aparatos. 相似文献

We discuss in the article the following issues: the strong relationship between collaboration and diversity; the need for understanding collaboration as a process of mutual acknowledgement and as a process of building in a democratic way; the strong influence for each participant of the concept of education over the process of building collaboration; the strong dependence of the process of collaboration on the institutional context, the school culture, and the requirements of the political and economical exponsors. This flexibility is a requirement for preserving the purpose of building a collaborative relationship in order to help improve the quality of practice through human development and institutional change. The basis for these reflections is the discussions we, as a group of researchers, had during the development of two action research-like projects in Malaga (Spain). An exploration of action research methodology in each of these two very different professional settings demonstrates how strongly action research methodology is determined by the culture of the participants and their institutions. As a consequence we conclude that every researcher has to take a flexible and changing role in order to meet the situational demands for building a collaborative relationship. 相似文献

The objective of this work is to investigate how most of the competences required by engineering students may be developed through an active methodology based on cooperative learning/evaluation. Cooperative learning was employed by the University of Huelva's third-year engineering students. The teaching methodology pretends to create some of the most relevant engineering skills required nowadays such as the ability to cooperate finding appropriate information; the ability to solve problems through critical and creative thinking; and the ability to make decisions and to communicate effectively. The statistical study carried out supports the hypothesis that comprehensive and well-defined protocols in the development of the subject, the rubric and cooperative evaluation allow students to acquire a successful learning. 相似文献

An experimental study was conducted comparing the effects of dual language, or two-way immersion (TWI) and monolingual English immersion (EI) preschool education programs on children's learning. Three-and four-year old children were randomly assigned by lottery to either a newly established TWI Spanish/English program or a monolingual English program in the same district. Children in the study were from both Spanish and English home language backgrounds. All classrooms in the study used the High/Scope curriculum, and all met high standards for teacher qualifications, ratio, and class size. The TWI program alternated between English and Spanish weekly by rotating children between two classrooms (and teachers) each week. Programs were compared on measures of children's growth in language, emergent literacy, and mathematics. Children in both types of classrooms experienced substantial gains in language, literacy, and mathematics. No significant differences between treatment groups were found on English language measures. Among the native Spanish speakers, the TWI program produced large gains in Spanish vocabulary compared to the EI program. Both TWI and EI approaches boosted the learning and development of children including ELL students, as judged by standard score gains. TWI also improved the Spanish language development of English language learners (ELL) and native English speaking children without losses in English language learning. 相似文献
