A longitudinal study of religious identity and participation during adolescence     

Lopez AB  Huynh VW  Fuligni AJ 《Child development》2011,82(4):1297-1309

To examine the development of religious identity during the teenage years, adolescents (N = 477) from Latin American, Asian, and European backgrounds completed questionnaires in the 10th, 11th, and 12th grades (10th grade age: M = 15.81, SD = 0.36). Results indicated that religious identity remained stable across high school whereas religious participation declined. Even after controlling for ethnic differences in religious affiliation, socioeconomic background, and generational status, adolescents from Latin American and Asian backgrounds reported higher levels of religious identity and adolescents from Latin American backgrounds reported higher rates of religious participation. Within individual adolescents, changes in religious identity were associated with changes in ethnic and family identities, suggesting important linkages in the development of these social identities during adolescence.  相似文献   

Familiarity with Latin and Greek anatomical terms and course performance in undergraduates     

Pampush JD  Petto AJ 《Anatomical sciences education》2011,4(1):9-15

Commonly used technical anatomy and physiology (A&P) terms are predominantly rooted in Latin and Greek vocabulary, so it is commonly inferred that a solid grounding in Latin and Greek roots of medical terminology will improve student learning in anatomy and related disciplines. This study examines the association of etymological knowledge of A&P terms and A&P course performance among 446 undergraduates in their first semester of the study of human gross anatomy and physiology, with a more detailed analysis of the characteristics of 52 students who filled out surveys about their prior knowledge and experiences related to medicine or anatomy. In both data sets, there was only a weak positive correlation between the performance on a quiz of Latin and Greek medical terms and the students' performance on regular assignments. The presumption that familiarity with Latin and Greek word roots has a strong influence on successful learning of anatomy is not supported by these data. Future research should address whether or not there are particular skills associated with using etymological knowledge in improving A&P course performance.  相似文献   

事业单位财务管理的几点建议     

张利军 《中国科技纵横》2011,(14):229-229

事业单位,是指国家为了社会公益目的,由国家机关举办或者其他组织利用国有资产举办的,从事教育、科技、文化、卫生等活动的社会服务组织。其资金主要来源于财政拨款。按财政拨款比例一般分为全额拨款事业单位、差额拨款事业单位及自主事业单位,即自收自支,国家不拨款的事业单位。事业单位是当前我国重要的公共部门机构,因此在当前经济社会中占有极其重要的地位。随着我国经济体制改革的不断深化及财政职能的转变,事业单位改革的步伐也在逐步加快,资金来源也正在由单纯靠财政拨款向多元化、多层次、多渠道转变,正在逐步走向社会,走向市场。建立起了以市场经济理论为指导、以财经法规为依据、以理财为重点、以有利于自身发展为目的的财务管理新机制。然而由于种种原因,许多事业单位财务管理工作还很薄弱,观念陈旧、老化,等、靠想严重。因此转变陈旧观念,充分利用国家财政资金,提高资金使用效益,加强财务管理,是当前事业单位财务管理工作的重中之重。  相似文献   

Membrane-integrated microfluidic device for high-resolution live cell imaging     

Epshteyn AA  Maher S  Taylor AJ  Holton AB  Borenstein JT  Cuiffi JD 《Biomicrofluidics》2011,5(4):46501-465016

The design and fabrication of a membrane-integrated microfluidic cell culture device (five layers,≤500 μm total thickness) developed for high resolution microscopy is reported here. The multi-layer device was constructed to enable membrane separated cell culture for tissue mimetic in vitro model applications and pharmacodynamic evaluation studies. The microdevice was developed via a unique combination of low profile fluidic interconnect design, substrate transfer methodology, and wet silane bonding. To demonstrate the unique high resolution imaging capability of this device, we used oil immersion microscopy to image stained nuclei and mitochondria in primary hepatocytes adhered to the incorporated membrane  相似文献   

Effect of post-match cold-water immersion on subsequent match running performance in junior soccer players during tournament play   总被引：2，自引：1，他引：1  

Rowsell GJ  Coutts AJ  Reaburn P  Hill-Haas S 《Journal of sports sciences》2011,29(1):1-6

In this study, we investigated the effects of two hydrotherapy interventions on match running performance and perceptual measures of fatigue and recovery during a 4-day soccer tournament. Twenty male junior soccer players were assigned to one of two treatment groups and undertook either cold-water immersion (5 × 1 min at 10 °C) or thermoneutral water immersion (5 × 1 min at 34 °C) after each match. High-intensity running distance (>15 km · h?1) and total distance covered, time spent in low (<80% maximum heart rate), moderate (80-90% maximum heart rate), and high (>90% maximum heart rate) heart rate zones, and rating of perceived exertion (RPE) were recorded for each match. Perceptions of general fatigue and leg soreness were recorded approximately 22 h after each match. There were decreases in both groups across the 4-day tournament for high-intensity running distance (P = 0.006, Cohen's d = 0.63), total distance run (P < 0.001, d = 0.90), time in high heart rate zone (P = 0.003, d = 0.90), and match RPE (P = 0.012, d = 0.52). Cold-water immersion was more effective than thermoneutral immersion for reducing the perception of leg soreness (P = 0.004, d = -0.92) and general fatigue (P = 0.007, d = -0.91), ameliorating the decrement in total distance run (P = 0.001, d = 0.55), and maintaining time in the moderate heart rate zone (P = 0.01, d = 1.06). In conclusion, cold-water immersion mediates the perceptions of fatigue and recovery and enhances the restoration of some match-related performance measures during a 4-day tournament.  相似文献   

中国服务贸易的竞争力现状及国际比较研究     

杨珂  张利军 《保山师专学报》2014,(4):84-90

自2001年入世以来,中国的服务贸易总量增长迅速,国际市场占有率不断提高。运用TC指数、RCA指数对2001—2012年的贸易数据进行分析,对中国服务贸易的竞争力的现状进行国际对比,发现中国与发达国家相比竞争力差距较大,传统行业如旅游、运输部门比重大但竞争力不强,知识或技术密集型的服务部门则发展缓慢。  相似文献   

晶粒尺寸对16 Mn 钢 MnS 夹杂物的应力应变分布影响     

姜丽华  ;赖运金  ;刘晓梅  ;张利军 《渭南师范学院学报》2014,(15):26-29

基于ABAQUS有限元分析方法,对两种热处理工艺下的16 Mn钢中MnS夹杂物在同一拉伸载荷作用下的应力和应变分布进行了研究。结果表明,两种晶粒尺寸的材料在长条形MnS夹杂物附近存在着垂直于加载方向的X形状的Mi-ses应力和PEEQ集中区。但细晶的16Mn钢中MnS引起的应力和应变集中程度要明显大于粗晶的16Mn钢中MnS引起的应力和应变集中,其原因与细晶强化有关。  相似文献

Creatine kinase activity weakly correlates to volume completed following upper body resistance exercise     

Machado M  Willardson JM  Silva DR  Frigulha IC  Koch AJ  Souza SC 《Research quarterly for exercise and sport》2012,83(2):276-281

In the current study, we examined the relationship between serum creatine kinase (CK) activity following upper body resistance exercise with a 1- or 3-min rest between sets. Twenty men performed two sessions, each consisting of four sets with a 10-repetition maximum load. The results demonstrated significantly greater volume for the 3-min condition (M = 4156 kg, SD = 867, for 3 min; vs. M = 3503 kg SD = 759, for 1 min; p < .001), with no significant differences in delta CK activity between conditions (p = .574). Nevertheless, there was a weak correlation between the delta CK activity and total volume of exercise completed (r = .55 with a 1-min rest, and r = .45 with a 3-min rest). Therefore, the volume following upper body resistance exercise correlates weakly with serum CK levels, irrespective of rest interval length between sets.  相似文献   

Visualizing carrier status: fragile X syndrome and genetic diagnosis since the 1940s     

Hogan AJ 《Endeavour》2012,36(2):77-84

What does it look like to be the carrier of a genetic disease? Carrier status may be determined through the visual analysis of both genotypic and phenotypic evidence. Over the past 70 years, clinical geneticists have depended upon multiple strategies for identifying disease carriers within a family. This has included pedigree analysis, which was based upon clinical observations of individual family members and, in recent decades, cytogenetic and molecular methods. Newer techniques have offered novel opportunities to actually see the suspected etiological markers of certain genetic diseases, such as Fragile X syndrome. The visualization of these markers has both clarified and confused previously observed inheritance patterns, in some cases leading to the development of newly distinct diagnostic categories. As a result, what it means to be affected by, or the carrier of, a genetic disease has continuously evolved.  相似文献
