Szwede Slavic Books, the largest Slavic bookstore in the United States, ceased operations in May 2010. However, throughout its operation, the bookstore made an enormous contribution to Slavic culture and Slavic library collections in the United States. In this article, the author introduces the owners, Irena and Jerzy Szwede, and longtime employee Vera Shemelis. Additionally, he discusses the firm, its books, and the special atmosphere of the store. 相似文献

Wyoming Community College Commission policy currently states any student enrolled for more than 12 credit hours will be charged tuition for only 12 credit hours. This policy is referred to as the tuition cap. In November 2010, the commission discussed increasing the tuition cap to 15 credits. An increase from 12 to 15 credits would have represented a 25% increase in tuition for students enrolled for 15 or more credits. Casper College president Dr. Walter Nolte commissioned a study to examine the impact such an increase would have on Casper College and its students. A survey instrument was designed to determine if students carrying more than 12 credit hours would reduce their enrollment credits and what sources of funding they would seek to defray the increased cost. Using a multistage sampling design, a sample of 67 Casper College course sections was selected to respond to the survey. The data were analyzed with logistic regression models, and the estimates were adjusted using sampling weights and a finite population correction. Analysis indicated that 42% of Casper College students would reduce their credit hours by an average of 3.3 credits. Approximately 58% of students would seek additional scholarships and 63% would seek increased work hours. The results of the study were presented to the Wyoming Community College Commission on October 28, 2011. In December 2011, the Commission announced a decision not to increase the tuition cap. 相似文献

Abstract We investigated balance in 33 competitive dancers (17 females, 16 males) and 22 controls (17 females, 5 males) (age 16–27 years) on a force plate in two conditions: single task (quiet stance) and dual task (with a concurrent mental task). Balance was evaluated using centre-of-pressure shift (sway) variability, mean speed, frequency, and sample entropy. The effect of the dual task in the medio-lateral plane was comparable in both groups, decreasing sway variability (P < 0.05) and increasing mean speed (P < 0.001), frequency, and sample entropy (P < 0.001), showing that the participants effectively increased the level of automaticity. In the antero-posterior plane, the dual task also increased sway frequency and sample entropy (P < 0.01) in dancers without affecting their standing performance. In contrast, postural control in non-dancers was vulnerable to reduced cognitive investment, which adversely interfered with baseline performance. There were very high correlations between sway sample entropy and frequency in each group, plane, and task (r = 0.92–0.98, P < 0.001), indicating that both parameters may measure the same characteristic of postural control and that higher sway frequency may play an important role in protecting stability in dual tasking. The postural control of dancers and non-dancers appears to be similar, although dancing seems to facilitate the increased level of automatic control in the antero-posterior plane. 相似文献

AbstractThis longitudinal study investigated visual evoked potentials (VEPs) in 11 young female volleyball players who participated in extensive training for 2 years. The control group consisted of 7 age-matched female students who were not involved in any regular sports activity. Recordings of VEPs were performed twice: baseline recording (i.e., before training began) and after 2 years of systematic, volleyball-specific athletic training. The effect of athletic training on visual signal conductivity was assessed by recording the latency of N75, P100 and N135 components of the VEPs waveform. Extensive experience with volleyball training reduced signal conductivity time through visual pathway. Specifically, the latency of P100 was reduced on average by 2.2 ms during binocular viewing. Moreover, athletes had reduced N75 latency (difference of 3.3 ms) for visual stimuli that generated greater response from peripheral retina. These results indicate that sport training can affect very early sensory processing in athletes. 相似文献

This paper addresses the mean-square consensus problems of continuous-time heterogeneous multi-agent systems with communication noises. First, in order to attenuate the communication noises, time-varying consensus gains are applied in the consensus algorithm. Then, by using the tools of algebraic graph theory and stochastic analysis, sufficient conditions for the mean-square consensus are given for the cases with and without a leader. Finally, simulations are provided to demonstrate the effectiveness of the proposed algorithms. 相似文献

AbstractThis paper addresses the massive scale of match-fixing in Polish football revealed by the corruption scandal which hit the headlines in the Polish media in 2005. Although more than a decade later the investigation is far from over, it is already clear that corruption was an everyday phenomenon ignored or purposely overlooked by bodies supervizing football competitions. The peculiarity of the Polish case stems from the fact that the match-fixing was not betting-related. The paper attempts to track the historical roots of corruption, paying particular attention to the period of communism (1945–1989) and the role of the Polish Football Association. Subsequently, several non-mutually exclusive sociological interpretations of the situation are discussed. 相似文献

The goals of our study were to determine the predictive value and usability of an audience response system (ARS) as a knowledge assessment tool in an undergraduate medical curriculum. Over a three year period (2006–2008), data were collected from first year didactic blocks in Genetics/Histology and Anatomy/Radiology (n = 42–50 per class). During each block, students answered clinically oriented multiple choice questions using the ARS. Students' performances were recorded and cumulative ARS scores were compared with final examination performances. Correlation coefficients between these variables were calculated to assess the existence and direction of an association between ARS and final examination score. If associations existed, univariate models were then constructed using ARS as a predictor of final examination score. Student and faculty perception of ARS difficulty, usefulness, effect on performance, and preferred use were evaluated using a questionnaire. There was a statistically significant positive correlation between ARS and final examination scores in all didactic blocks and predictive univariate models were constructed for each relationship (all P < 0.0001). Students and faculty agreed that ARS was easy to use and a reliable tool for providing real‐time feedback that improved their performance and participation. In conclusion, we found ARS to be an effective assessment tool benefiting the faculty and the students in a curriculum focused on interaction and self‐directed learning.

Age of Bilingual Exposure Is Related to the Contribution of Phonological and Semantic Knowledge to Successful Reading Development 下载免费PDF全文
Bilingual children's reading as a function of age of first bilingual language exposure (AoE) was examined. Bilingual (varied AoE) and monolingual children (N = 421) were compared in their English language and reading abilities (6–10 years) using phonological awareness, semantic knowledge, and reading tasks. Structural equation modeling was applied to determine how bilingual AoE predicts reading outcomes. Early exposed bilinguals outperformed monolinguals on phonological awareness and word reading. Phonology and semantic (vocabulary) knowledge differentially predicted reading depending on the bilingual experience and AoE. Understanding how bilingual experiences impact phonological awareness and semantic knowledge, and in turn, impact reading outcomes is relevant for our understanding of what language and reading skills are best to focus on, and when, to promote optimal reading success. 相似文献
