In the United States, public television claims itself a champion of localism. A prime-time schedule analysis of the Public Broadcasting Service's (PBS) member stations establishes localism scores, and discriminant analysis finds variables that predict differences among stations. Market level variables (income, education, ethnic diversity, geographic component) and organizational level variables (Community Service Grants, membership funding, overall revenue) affect localization of member stations' schedules. This is the first empirical study utilizing a structural operationalization of localism, inclusive of all programming genres, applied to PBS member stations. 相似文献

Poverty‐related developmental‐risk theories dominate accounts of uneven levels of household functioning and effects on children. But immigrant parents may sustain norms and practices—stemming from heritage culture, selective migration, and social support—that buffer economic exigencies. Comparable levels of social‐emotional functioning in homes of foreign‐born Latino mothers were observed relative to native‐born Whites, despite sharp social‐class disparities, but learning activities were much weaker, drawing on a national sample of mothers with children aging from 9 to 48 months (n = 5,300). Asian‐heritage mothers reported weaker social functioning—greater martial conflict and depression—yet stronger learning practices. Mothers’ migration history, ethnicity, and social support helped to explain levels of functioning, after taking into account multiple indicators of class and poverty. 相似文献

The features of Korean higher education development are related to sociocultural tradition (Confucian tradition), the model
university ideas, and economic development in Korea. The modern university ideas adopted in Korean are based on the German
model which was established by the Japanese colonial government and drawing on the US university model after the World War
II. However, the modern university ideas are intertwined with socio-cultural factors and have been embedded in current Korean
universities. As well as the western ideas and the Confucian tradition, the growth of Korean higher education has relied upon
the rapid growth of the Korean economy. Education development is well aligned with economic development in Korea thanks to
government policy initiatives. This framework can be applied in the analysis of higher education development in other countries.
Higher education development cannot be solely explained by individual cultural, historical or economic factor. These three
factors are interlinked and influence the development of Korean higher education. 相似文献

An electroencephalogram (EEG)-based brain–computer interface (BCI) speller allows a user to input text to a computer by thought. It is particularly useful to severely disabled individuals, e.g. amyotrophic lateral sclerosis patients, who have no other effective means of communication with another person or a computer. Most studies so far focused on making EEG-based BCI spellers faster and more reliable; however, few have considered their security. This study, for the first time, shows that P300 and steady-state visual evoked potential BCI spellers are very vulnerable, i.e. they can be severely attacked by adversarial perturbations, which are too tiny to be noticed when added to EEG signals, but can mislead the spellers to spell anything the attacker wants. The consequence could range from merely user frustration to severe misdiagnosis in clinical applications. We hope our research can attract more attention to the security of EEG-based BCI spellers, and more broadly, EEG-based BCIs, which has received little attention before. 相似文献

This qualitative study probed into (a) the sense of fulfillment, (b) fears and anxieties, and (c) life trajectories of aged working professors recruited from one comprehensive university in the Philippines. Interestingly, findings of the study reveal that respondents were fulfilled and felt successful through the life outputs of their students; their self-worth was witnessed through continued employment and communication to students of ideas, work ethic, and values. Fears and anxieties were rarely felt because of religious commitments and prayers to God. Sense of delight was manifested through the satisfactory academic environment; the possession of supportive systems, including family, friends and community, and their plans of spending their remaining years with the family in leisure activities; and in joining religious organizations. 相似文献

The purpose of this study is to explore USA educators' resistance toward cultural awareness for Korean students and families in the New York metropolitan area. The authors aim to challenge teachers' color-blindness that is widely spread among USA educators. Guided by critical race theory, the authors show that the perceived fairness of color-blindness could cause struggles for Korean parents and students in American schools. The authors posit USA teachers need to thoroughly understand that if a teacher does not see color, then s/he does not really see children. This study, hopefully, will help educators recognize the necessity of understanding diverse ethnic parents' perspectives and needs. Also, this study will provide an opportunity for educators to rethink assumptions that are embedded in color-blindness, and advance muiticultural education that is more culturally relevant and responsive for different ethnic/racial groups' needs. 相似文献

ObjectiveThis study aimed to examine (1) the independent effects of hypoxia on cognitive function and (2) the effects of exercise on cognition while under hypoxia.MethodsDesign: Systematic review with meta-analysis. Data sources: PubMed, Scopus, Web of Science, PsychInfo, and SPORTDiscus were searched. Eligibility criteria for selecting studies: randomized controlled trials and nonrandomized controlled studies that investigated the effects of chronic or acute exercise on cognition under hypoxia were considered (Aim 2), as were studies investigating the effects of hypoxia on cognition (Aim 1).ResultsIn total, 18 studies met our inclusionary criteria for the systematic review, and 12 studies were meta-analyzed. Exposure to hypoxia impaired attentional ability (standardized mean difference (SMD) = –0.4), executive function (SMD = –0.18), and memory function (SMD = –0.26), but not information processing (SMD = 0.27). Aggregated results indicated that performing exercise under a hypoxia setting had a significant effect on cognitive improvement (SMD = 0.3, 95% confidence interval: 0.14 – 0.45, I2 = 54%, p < 0.001). Various characteristics (e.g., age, cognitive task type, exercise type, exercise intensity, training type, and hypoxia level) moderated the effects of hypoxia and exercise on cognitive function.ConclusionExercise during exposure to hypoxia improves cognitive function. This association appears to be moderated by individual and exercise/hypoxia-related characteristics. 相似文献

This letter proposes a categorization matrix to analyze the playing style of a computer game player for a shooting game genre. Our aim is to use human-centered modeling as a strategy for adaptive games based on entertainment measure to evaluate the playing experience. We utilized a self-organizing map (SOM) to cluster the player's style with the data obtained while playing the game. We further argued that style-based adaptation contributes to higher enjoyment, and this is reflected in our experiment using a supervised multilayered perceptron (MLP) network. 相似文献
