In the context of intense debate over immigration into the United States, the television show Border Wars offers a distinctive way for anxious citizens to participate in reinforcing the border. In the program, viewers are invited to share the lines of site of Customs and Border Patrol (CBP) agents as they conduct surveillance of unauthorized border crossers. Because Latino bodies are repeatedly displayed as the subjects of surveillance, the positions of viewer/citizen and viewed-non-citizen encourage racial alignments with the border. In the face of these alignments, the Latino CBP agents are made readable as bodies in transition toward citizenship due to their performance of surveillance practices against other Latinos. The article comments on the soldier citizen as positioned at the panoptic center of watching without being watched, which is less available to Latinos because their bodies circulate as signs of suspicion, which casts them disproportionately onto the surveillance screen. Practices of surveillance should be understood as performances because they reaffirm Americans of their citizenship status at a time of heightened paranoia over the loss of a stable identity.  相似文献

The surviving gilded and polychrome altarpieces and sculptures in Portuguese churches, and the historical documents relating to them, offer an opportunity for understanding material and technological choices regarding gesso grounds. This paper focuses on the historical documentary research about gessoes — one aspect of a wider research project which also involved investigation of physical/chemical evidence, and archaeological reconstructions of gilded gesso grounds. Documentary research sheds light on the meaning of the terms used in historical documents, and on artists’ choice of materials and practices, production, and trade patterns of materials. It informs technological investigations and conservation decisions. The paper also stresses the importance of the evidence gained by using the historical and archaeological methodology applied in material culture studies, in which documentary, analytical, and experimental information complement and/or elucidate each other, leading to a comprehensive understanding of this technology.  相似文献

Most research into interactions between mothers and their infants with hearing impairments focuses on mothers' and infants' behaviors separately, speculating about the interplay among these behaviors and their effects on child development. In the present article, an intersubjective developmental theory focusing on the development of the "interworld" between deaf and hearing mothers and their deaf infants is used to integrate and interpret the seemingly incoherent research on early mother-deaf child interaction. Inspired by Stern's work (e.g., Stern, 1985), the intersubjective developmental theory distinguishes four stages in the development of intersubjectivity: emerging (birth-2 months), physical (2-8 months), existential (8-13 months), and symbolic (13 months and older), each characterized by a different type of mother-infant interaction. The integration of research findings on early mother-deaf child interaction into these four developmental stages offers new perspectives that can advance research and resolve certain early-intervention issues.  相似文献

The principal aim of this research is to contrast empirically a hypothetical model developed on the basis of the fundamental assumptions of current self-regulated learning models. In line with evaluation criteria of model fit, a high rate of congruence between the hypothesized theoretical model and the empirical data was observed. Analysis of the effects between the variables of the model revealed the following relevant aspects: students' predisposition to feel responsible for the results of their academic behavior (internal attribution) is related to positive self-image (academic self-concept), both being important conditions for development of learning-oriented motivation (learning goals). All of this involves selection and use of learning strategies for deep information processing (deep learning strategies), which leads students to assume responsibility with high levels of persistence, perseverance, and tenacity so as to achieve goals defined by the motivational orientation. This persistence and effort to achieve the proposed goals has in turn a positive and significant effect on academic achievement.  相似文献

The results are described of two case studies on the conceptions and classroom practice of two Portuguese physics and chemistry teachers on the role of problem solving in the teaching/learning of science. One of these teachers was a novice and the other had about 20 years of teaching experience. The data were obtained from a questionnaire, a semi-structured interview, classroom observation, personal documents, and stimulated recall. The analysis was carried out with instruments organised into categories and specific indicators. The results showed there to be major differences between the intention behind the new curricula, the teachers' conceptions, and their practice. Some suggestions are put forward on the basis of these results for the initial and ongoing education of secondary education teachers of physics and chemistry in Portugal.  相似文献

We present, in this article, an investigation about the potential of the relationship between formal and non-formal educational environments. Therefore it is not an empirical research, but an essay on the topic. This paper demonstrates the concept that science education and science outreach can be privileged by actions that are developed by closer relations between formal and non-formal places. Currently, non-formal environments such as museums and science and technology centres are considered potential educational resources within the reach of schools. Educators from museums have conducted studies which demonstrate a predominant model of the utilization of these institutions by teachers, which consists of illustrative visits during the exhibitions, but does not feature a collaborative relationship or partnership between schools and these institutions. In Brazil, the main examples of approaches to collaboration between these places and schools have been taking place through the initiatives of teachers or through projects developed by the educational sector, aiming to broaden the dialogue between their institutions and the school community. Another approach mechanism relates to research and extension projects developed by university researchers, sponsored by state and federal funding agencies. In this case, the universities and university museums appear as new social actors that stand in the way of the schools and the cultural environments, complicating the relationship and, at the same time, bringing new questions to the field of educational research. We believe that the discourse in this paper should bring about further discussions in the initial teacher training courses to contribute to the understanding of practices related to the extension of the field of activity of the school.  相似文献

Empirical evidence on the effectiveness of R&D subsidies to firms has produced mixed results so far. One possible explanation is that firms and project selection rules may be quite heterogeneous both across agencies and across industries, leading to different outcomes in terms of the induced additional private effort. Here we focus on the participation stage. Using a sample of Spanish firms, we test for differences across agencies and industries. Our results suggest that firms in the same industry face different hurdles to participate in different agencies’ programs, that participation patterns may reflect a combination of agency goals, and that patterns differ across high-tech and low-tech industries.  相似文献

The aim of this article is twofold: (a) to validate the psychometric properties of the Academic Resilience Scale (AR‐S) in a Spanish university context; and (b) to test a model where different coping strategies are antecedents of AR, and where academic satisfaction and performance are its consequences. The studies were conducted with 185 (study 1) and 780 (study 2) students. In study 1, the construct validity, reliability, and convergent and divergent validity of the AR‐S were analyzed. The hypothesized model (study 2) was tested using structural equation modeling. The results confirmed the good psychometric properties of the AR‐S in the Spanish context, providing evidence of its validity. Furthermore, the distinctive role of different coping strategies in resilience was confirmed, as well as the relationship between resilience and academic satisfaction. No direct relationship between resilience and performance was found, highlighting the full mediation of satisfaction.  相似文献
