There is widespread belief that exposure to television has harmful effects on children's cognitive development. Most studies that point to a negative correlation between hours of television watching and cognitive outcomes, fail to establish causality. Using the National Longitudinal Survey of Youth (NLSY) we study young children between 5 and 10 years of age during late 1990s and early 2000s. We find strong evidence of negative correlations between hours of television watched and cognitive test scores. However, once parent's characteristics and unobserved child characteristics are taken into account these correlations go away. We find that hours of television viewed per se do not have any measurable impact on children's test scores. Our results are robust to different model specifications and instrumental variable estimates. We conclude that despite the conventional wisdom and the ongoing populist movement, proactive policies to reduce children's television exposure are not likely to improve children's cognitive development and academic performance.  相似文献

In structuring the programme of our interior design studio, we questioned two assumptions that are central to the discourse of modern architecture: the site being empty of its unique traits, images, stories; and the user being devoid of human subjectivities, perception, imagination, memory. The two projects we relate here, titled Interpretations and (Dis)connections, address threshold/boundary conditions. Throughout four stages of Interpretations, we tried to challenge the concepts of ‘empty space’ and ‘universal man’ either by leaving site as well as user outside of our construct or capitalizing specifically on their entire load. (Dis)connections, on the other hand, was based on interpretations of a film, a reference outside the functional paradigms of architecture. Themes/constructs/patterns identified in the film generated design ideas, then programmes, sites and, finally, designs through a sequence of transitions and transformations. This entire process enabled the reconsideration of relations between building/site and building/user and other provided possibilities for questioning the boundaries of the discipline of architecture itself.  相似文献

The purpose of this article is to provide a review of background information regarding perceived level of personal control over the physical features of the work environment and its impact on individual satisfaction and outcomes. In today's business with the fast growth of technology, e‐market development, and innovative methods of communication, the workplace will continue to change rapidly. To control and accommodate these fast changes while sustaining or enhancing outcomes, organizations have increasingly turned to a model of work teams; therefore, employees’ skills in working within team environments has been emphasized. To guarantee that the work environment itself supports these new approaches of working, flexible workplaces are often suggested. Open‐plan offices offer more flexibility when compared to completely closed and private ones and they are considered to have more capabilities and are, therefore, highly valued in today's industry. Apart from its advantages, open‐plan office design does create some problems due to lack of personal control over the work environment, which can negatively affect employees’ satisfaction and performance. It is, therefore, important to emphasize the significance of personal control over the physical work environment and the impact of that on employees’ satisfaction and outcome.  相似文献

An institutional repository is a system for dissemination and stewardship of the intellectual life and scholarship of an institution. It has become a new way for the institutions to contribute to the broader world of scholarship (Giesecke, 2011 Giesecke, J. (2011). Institutional repositories: Keys to success. Journal of Library Administration, 51(5–6), 529542. Retrieved January 3, 2013, from http://digitalcommons.unl.edu/libraryscience/255[Taylor & Francis Online] [Google Scholar]). In spite of the global recognition of institutional repositories as an open access scholarly communication channel, institutional repositories are still struggling with the problem of non-participation from contributors in developing countries like India. This study conveys the results of a survey conducted at a minority university of India. The study is an expression of the opinion of 542 faculty members and research scholars pertaining to the possible implications of institutional repositories on their professional and publishing practices. The study is undertaken to: Determine the level of awareness of institutional repository among contributors; identify the reasons for participation and non-participation of contributors; examine the implications of institutional repository on contributors professional and publishing practices; analyze the major obstacles/hindrances in the growth of an institutional repository; and suggest measures for better implementation and development of an institutional repository in future. With the help of the statistical techniques such as chi-square test and weighted mean the study resulted that the majority of the contributors are well aware about the concept of institutional repository, the majority of contributors have not deposited in an institutional repository so far, long term preservation of research materials is the first ranked reason for participation in an institutional repository, copyright and plagiarism concern is the main reason behind contributors’ non-participation in institutional repository, increased accessibility of research output is the major implication of the institutional repository on contributors professional practices, saved cost of publishing in a journal is the biggest implication of institutional repository on contributors publishing practices, and contributors demand more control on ownership, access and security in future for an institutional repository. This article is aimed at the institutions that report low-use and low-deposit repositories. It may be used to convince the contributors about the value of institutional repositories, importance of participating in an institutional repository and possible implications on their professional and publishing practices. The study is also intended at the management of the institutions to take notice of the contributors’ demands for future participation and develop policies accordingly for removing major barriers in the growth of institutional repositories and improving contributions and quality of content in the institutional repositories.  相似文献

Research into cultural differences in higher education is a growing phenomenon, and there is a need to establish a theoretical framework that supports Business Schools in the personalisation of the pedagogical process. This article investigates the role of Business School academics in shaping the pedagogical process that is culturally responsive to the unprecedented diversity in higher education. This article attempts to uncover the pedagogical machinations that govern how academics teach, interact and engage with their culturally and ethnically diverse students. The article argues that University Business Schools should consider a culturally responsive approach when formulating pedagogy, which takes into account prior student experience as part of the student learning. The notion of culturally responsive teaching that shapes this research is influenced by US research on education and diversity. Such a perspective begins with an acceptance of the rights of not only teachers but also learners.  相似文献

This paper gives a comprehensive account of the development of library and information science education in Africa. Ghana was first to start any kind of library education in 1944 but the formal education started at Ibadan, Nigeria in 1959. By 1970 there were six library schools; four new schools started during 1970s and another six during 1980s. Two Regional Schools with Master's programme in Information Science started in 1990. Two new schools are likely to start soon. Nigeria alone has eight schools providing professional education at all levels including PhD (which is only available in Nigeria) and an exclusive programme of Master in Information Science at ARCIS, Ibadan. Several schools, realizing the importance of new developments in information science and technology, are planning to incorporate this component into their curriculae. The existing programmes need to be assessed in context of information needs of Africa.  相似文献

Psychological flexibility is associated with psychological health and affected by various factors. The aim of the present study is to examine the role of coronavirus anxiety, humor and social media addiction on psychological flexibility during the COVID-19 pandemic in Turkey. Variables were measured with online self-report surveys and data were gathered from December 2020 to January 2021 in Turkey. The sample consisted of 376 people (295 female, M?=?29.88, SD?=?11.05). The relationships between the variables were tested with path analysis using structural equation modelling (SEM). According to results, the constructed model showed that COVID-19 anxiety significantly and directly increased social media addiction (β?=?.17, p?<?.01), decreased coping humor (β?=?-.11, p?<?.05) and decreased psychological flexibility indirectly through social media addictions (β?=?-.08, p?<?.01). Humor coping significantly and directly increased psychological flexibility (β?=?.25, p?<?.01), and social media addiction significantly and directly decreased psychological flexibility (β?=?-.31, p?<?.01). Findings indicated that psychological flexibility is influenced by coronavirus anxiety, social media addiction and humor coping.  Supporting humor coping and reducing anxiety and problematic social media use would be helpful to enhance psychological flexibility of individuals during the pandemic.
