Passed in 2000, the Children's Internet Protection Act (CIPA) mandates Internet filtering for all public schools and libraries. Challenges to the law have been raised on constitutional grounds by free-speech advocates such as the American Library Association and the American Civil Liberties Union. After losing one such challenge in district court, the federal government appealed to the U.S. Supreme Court, where the law was upheld in June 2003, though not without possible future concerns. CIPA has profound implications for K–12 school leaders and technology specialists, and a history of the law reveals much about its origins and purpose. 相似文献

Colleges and universities face a principal-agent problem. There are information asymmetries over the actions chosen by administrators. Because non-profit constraints limit the financial stake of trustees there may be insufficient monitoring of administrators and, consequentially, shirking. It is conceivable that faculty will serve as “delegated monitors” given the proper incentives. Faculty monitoring will most likely benefit a university when: (1) monitoring costs are low and (2) administrators cannot impose significant punishment costs on faculty. The practices of organized faculty participation in governance and tenure naturally achieve such ends. Empirical evidence from a sample of colleges and universities in the United States supports the hypothesis that features of a faculty's employment have significant effects on a university's financial performance. 相似文献

This study examined the dispositions, experiences, and expectations of international students in a developing country to understand
the increasing phenomenon of reverse student flows and the role of the political economy in international student mobility.
Students’ dispositions, experiences and expectations—referred here collectively as “orientations”—served as the guiding framework
for this study. Data were drawn from survey responses from 279 international students at universities throughout Mexico and
analyzed to explore the orientations among students from Europe, Latin America and North America. Findings showed significant
differences among international students’ dispositions, experiences, and expectations by these geographical regions of origin.
In a broader context, this research addressed the important role of developing countries as not only senders but also receivers
of international students. This research also demonstrated the ways that the political economy shape the orientations of students
studying abroad. 相似文献

Four stories: confronting contemporary ideas about globalisation and internationalisation in higher education 总被引:1,自引:1,他引:0
There is a common distinction between globalisation and internationalisation in higher education scholarship. Globalisation is seen as an over‐arching social and economic process where as internatinalisation is understood as the ways in which institutions of higher education respond to globalisation. This conceptual distinction has also worked its way into the practice of university administration around the world. Drawing on the theoretical work of Foucault and Giddiness, this conception the consequences of the globalisation / internationalisation distinction are analysed through four of higher accounts education strategies. 相似文献

Increasing knee stability via appropriate muscle activation could reduce anterior cruciate ligament (ACL) injury risk during unplanned sidestepping. High-level athletes may activate their knee muscles differently from low-level athletes when responding to quasi-game realistic versus non game-realistic stimuli. Eleven high-level and 10 low-level soccer players responded to a non game-realistic arrow-planned condition (AP), a quasi game-realistic one-defender scenario (1DS) and two-defender scenario (2DS), and an arrow-unplanned condition (AUNP), that imposed increasing time constraints to sidestep. Activation from eight knee muscles during sidestepping was measured during pre-contact and weight-acceptance. Knee flexor-extensor co-activation ratios were established. Muscle activation levels increased by approximately 27% solely in the 1DS in both sidestepping phases. In the 2DS, the shift from a flexor dominant co-activation strategy in pre-contact toward extensor dominance in weight-acceptance commenced earlier for the high-level players. Quasi game-realistic information allowed for anticipatory increases in knee muscle activation regardless of expertise levels but only when the time demands to respond were low (1DS). High-level players were better at interpreting complex game-realistic information (2DS) to activate their knee extensors earlier in preparation for single-leg landing during weight-acceptance. 相似文献

This study investigated the effects of two separate doses of sodium bicarbonate (NaHCO3) on 4 km time trial (TT) cycling performance and post-exercise acid base balance recovery in hypoxia. Fourteen club-level cyclists completed four cycling TT’s, followed by a 40 min passive recovery in normobaric hypoxic conditions (FiO2 = 14.5%) following one of either: two doses of NaHCO3 (0.2 g.kg?1 BM; SBC2, or 0.3 g.kg?1 BM; SBC3), a taste-matched placebo (0.07 g.kg?1 BM sodium chloride; PLA), or a control trial in a double-blind, randomized, repeated-measures and crossover design study. Compared to PLA, TT performance was improved following SBC2 (p = 0.04, g = 0.16, very likely beneficial), but was improved to a greater extent following SBC3 (p = 0.01, g = 0.24, very likely beneficial). Furthermore, a likely benefit of ingesting SBC3 over SBC2 was observed (p = 0.13, g = 0.10), although there was a large inter-individual variation. Both SBC treatments achieved full recovery within 40 min, which was not observed in either PLA or CON following the TT. In conclusion, NaHCO3 improves 4 km TT performance and acid base balance recovery in acute moderate hypoxic conditions, however the optimal dose warrants an individual approach. 相似文献
