In the 1990s, most US states adopted new forms of performance-based accountability, e.g., performance-based budgeting, funding, or reporting. This study analyzed changes in institutional performance following the adoption of these new accountability standards. We measured institutional performance by representative education and research indicators—graduation rates and levels of federal research funding. We collected data from 1997 to 2007 and used a hierarchical linear modeling growth curve analysis. The main finding was that states which adopted performance-based accountability did not see a noticeable increase in institutional performance. In addition, we highlighted a critical policy issue—whether state and institutional factors contribute most to institutional performance in higher education.  相似文献

This study examines which factors make a difference in distance learners’ achievements and also their continuous enrolment status over one year in Korea National Open University. A path analysis revealed that while learners’ job load had no directly significant effect on grade‐point average (GPA), it had a significant indirect effect on GPA via the study time variable. In addition to study time, social integration and extra face‐to‐face activities were found to be significant variables acting on their GPA. In predicting subsequent enrolment, face‐to‐face activities were the most influential up to a year later. The results of this study challenges the prevalent view that GPA has something to do with drop‐out, suggesting that learner progress toward achievement and drop‐out may be understood better when viewed separately, especially in the case of long‐term distance learning.  相似文献

The present study examines the role of communication in shaping norms and behaviors with significant personal and societal consequences. Based on primary socialization theory and the general theory of family communication, parental anti-substance-use socialization processes were hypothesized to influence early adolescents’ substance-use norms and behaviors. Using longitudinal data (N?=?1059), the results revealed that parent-adolescent prevention communication about substance use in the media and parental anti-substance-use injunctive norms were positively associated with early adolescents’ personal anti-substance-use norms, which, in turn, led to decreases in recent alcohol, cigarette, and marijuana use. It was also found that family expressiveness and structural traditionalism positively related to the hypothesized association between parental socialization processes and early adolescents’ norms and behaviors.  相似文献

Two complementary studies focused on stability of infant temperament across the 1st year and considered infant age, gender, birth order, term status, and socioeconomic status (SES) as moderators. Study 1 consisted of 73 mothers of firstborn term girls and boys queried at 2, 5, and 13 months of age. Study 2 consisted of 335 mothers of infants of different gender, birth order, term status, and SES queried at 6 and 12 months. Consistent positive and negative affectivity factors emerged at all time points across both studies. Infant temperament proved stable and robust across gender, birth order, term status, and SES. Stability coefficients for temperament factors and scales were medium to large for shorter (< 9 months) interassessment intervals and small to medium for longer (> 10 months) intervals.  相似文献

The Asian Games have exercised an influence over the Asian region which has been strong enough to change the paradigms of host countries having substantial socio-cultural effects on various elements of relationships such as geopolitical diplomatic relations in the region. South Korea has confidently hosted three Asian Games in the last two decades, the 1986 Seoul, 2002 Busan and 2014 Incheon Games. In this study, an investigation of the socio-cultural impacts of the Asian Games held in South Korea in the last two decades is carried out. The focuses of the study are the aspects of globalization, regionalism and reconciliation featured through the three Games. The outcomes of the study may contribute to the understanding of the role of mega sports events in promoting globalization of society and in intertwining with regional states. The Asian Games, as witnessed, which are held while maintaining the motto of the Olympics within Asia, will not only promote the globalization of host countries and cities in the future, but also it will contribute to improving diplomatic relations with neighbouring countries. These games are also predicted to help relieve political tension in the Asia-Pacific region, including the Korean Peninsula. However, as the effects of hosting mega sports events are largely concentrated on the development of their host countries and cities, these events also have the potential to become the seeds of regional conflicts or disputes by creating further competition or a sense of alarm.  相似文献

The present study tested the hypothesis that maturing prefrontal lobes play a role in the development of proportional reasoning skill because the prefrontal lobes are involved in the inhibition of task‐irrelevant information and the representation of task‐relevant information. The hypothesis that reasoning development is in part dependent upon physical experience was also tested. Students (all males) who failed to solve a diagnostic proportions task were administered several tests of prefrontal lobe functions. The students were then randomly assigned to manipulative or verbal tutoring groups. Both groups received a series of individual testing, tutoring and testing sessions on proportional reasoning. As predicted, performance on the prefrontal lobe tasks (measures of inhibiting ability, planning ability, dissembedding ability, and working memory capacity) significantly predicted performance on proportional reasoning tasks following tutoring. Students' computational skills were not a significant predictor. Also, the manipulative group's proportional reasoning performance was significantly higher than that of the verbal tutoring group. Therefore, the present results provide support for the hypothesis that maturing prefrontal lobes and physical experience play roles in the development of proportional reasoning skill. © 2000 John Wiley & Sons, Inc.

Abstract

This article examines Korea’s politics of identity in the form of Asianism in the modern period, especially since Korea’s incorporation into the modern world system in the late nineteenth century. Asianism, and regionalism generally, has become a salient policy strategy for the current South Korean government. However, Asianism has been a primary ideological current in modern Korea whose most recent incarnation should be understood in the larger historical context. This study traces the development of Asianism in four different periods: precolonial, colonial, Cold War, and post‐Cold War. Initially emerging as a bulwark against Western encroachment, the Asianism narrative became irrelevant upon Japanese annexation of Korea in 1910 and only survived as a discourse about a glorified cultural past during colonial rule. Upon liberation, Asianism rescinded as the Japan‐centered regional order was replaced by a new Cold War alignment, capitalist (Japan, South Korea, and Taiwan) versus communist (China and North Korea). Although discussion about Asianism and a new East Asian regional order have recently resurfaced, the historical legacy of colonialism, war, and national division has added much complexity to the debate. Explicating how the Asianism narrative emerged and evolved through these various historical contexts sheds light on the complexities and difficulties inherent in the current attempt to forge an Asian regional order. By looking at Asianism from a historical perspective, we can also better appreciate the continuity and discontinuity in Korea’s politics of identity. While it is still uncertain what the foundation of a new Asianism will be, it is equally obvious that regional interactions will continue to be an important part of the global world order. This study concludes with policy implications of how a historically sensitive understanding of the development of an Asian regional identity can further interaction and integration of East Asian nations.  相似文献

ABSTRACT

Korean Modern Art History began to be produced in the 1970s, when Western Modernist Art History, based on Formalism, was introduced as a matrix to map the ‘evolution’ of 20th century Korean Art. Korean modern art history is based in the same paradigm as the West, beginning with Impressionism and ‘ending’ with Abstract Expressionism. First introduced to the country from the West immediately after the Korean War, Korean Abstract Expressionism is now deemed as South Korea’s ultimate ‘progressive’ and ‘modern’ art form, a ‘Korean’ painting style combining the Western art form with traditional artistic concepts of ‘Scholarly Painting’ (muninhwa). Japanese‐influenced painting styles originating in the colonial period (1910–45) are rejected as ‘non‐authentic.’ The problem is that Scholarly Painting was a gender and class specific art born from the rigid Confucian culture of pre‐modern Korea, and thus its revival as an ‘ultimate modern’ and ‘Korean’ form has the consequence of locating traditionally‐gendered notions of art and artist at the core of the South’s modern art. This essay uses a Semiotic approach to deconstruct this gendered modernist rhetoric by tracing the emergence of the sign ‘Koreaness’ in South Korean modern art, showing how it is defined within Korean Abstract Painting as an ‘ultimate Korean sign’ and how its use of anti‐Japanese rhetoric covers up the traumatic history of the Korean War.  相似文献

This paper focuses on four fusion algorithms for the estimation of nonlinear cost function (NCF) in a multisensory environment. In multisensory filtering and control problems, NCF represents a nonlinear multivariate functional of state variables, which can indicate useful information of the target systems for automatic control. To estimate the NCF using multisensory information, we propose one centralized and three decentralized estimation fusion algorithms. For multivariate polynomial NCFs, we propose a simple closed-form computation procedure. For general NCFs, the most popular procedure for the evaluation of their estimates is based on the unscented transformation. The effectiveness and estimation accuracy of the proposed fusion algorithms are demonstrated with theoretical and numerical examples.  相似文献
