Objective We hypothesized that the drinking behavior of adolescents in China is influenced by expectancies and self‐efficacy and that adolescents' cultural orientation towards western versus traditional Chinese values influences expectancies, self‐efficacy and drinking behavior, with western values leading to more dysfunctional patterns of beliefs and drinking, and that these beliefs are influenced by students' gender and school environment. Methods A total of 1020 high school students from Beijing completed the Chinese Adolescent Alcohol Expectancy, the Chinese Cultural Orientation and the Chinese Self‐regulation Self‐efficacy questionnaires. Results Results generally confirmed our hypotheses. Higher negative expectancies and higher self‐efficacy reduced the likelihood of drinking significantly. Higher positive expectancies increased the likelihood of regular drinking but not occasional drinking. Having western cultural orientation increased the likelihood of drinking. Higher levels of western cultural orientation also increased positive expectancies, lowered negative expectancies and lowered self‐efficacy. Having more western (less traditional) views towards traditional Chinese values decreased positive and negative expectancies. Gender influenced beliefs, with males having higher positive and lower negative expectancies, lower self‐efficacy and more traditional cultural orientation. Students in key and general schools had less traditional cultural orientation and key school students had higher self‐efficacy. Conclusions Results indicate that cultural orientation influences adolescent drinking and this influence is mediated partially through cultural orientation influences on adolescent drinking expectancies and self‐efficacy. Having more western and less traditional Chinese cultural orientation leads to more drinking, lower self‐efficacy for regulating drinking and more risk‐promoting alcohol expectancies. 相似文献

Numerical studies for polymer composites deposition additive manufacturing have provided significant insight promoting the rapid development of the technology. However, little of existing literature addresses the complex yet important polymer composite melt flow–fiber orientation coupling during deposition. This paper explores the effect of flow–fiber interaction for polymer deposition of 13 wt.% Carbon Fiber filled Acrylonitrile Butadiene Styrene (CF/ABS) composites through a finite-element-based numerical approach. The molten composite flow in the extrusion die plus a strand of the deposited bead contacting the deposition substrate is modelled using a 2D isothermal and incompressible Newtonian planar flow model, where the material deposition rate is ~110 mm/s simulating a large scale additive manufacturing process. The Folgar–Tucker model associated with the Advani–Tucker orientation tensor approach is adopted for the evaluation of the fiber orientation state, where the orthotropic fitted closure is applied. By comparing the computed results between the uncoupled and fully coupled solutions, it is found that the flow-orientation effects are mostly seen in the nozzle convergence zone and the extrusion-deposition transition zone of the flow domain. Further, the fully coupled fiber orientation solution is highly sensitive to the choice of the fiber–fiber interaction coefficient , e.g., assigning as 0.01 and 0.001 results in a 23% partial relative difference in the predicted elastic modulus along deposition direction. In addition, Structural properties of deposited CF/ABS beads based on our predicted fiber orientation results show favorable agreements with related experimental studies. 相似文献

清代后中国文学的史学定位在现代文学内部划分为民国时期文学和共和国时期文学。与现代文学的意义概念不同的是,民国文学和共和国文学在中国现代文学的框架内都仅仅是一个时间概念。放弃文学史研究的整体主义努力,以多样主义或归纳主义的心态面对历史。中国现代文学的起点在1912年为各种争论的最大公约数,各种起点事件均看着是与起点联系的相关事件。先锋与常态的理论发现为一体两翼的成立找到理论依据。"民国机制"与"民国文学机制"的提出拓展了民国文学的研究思路,但本身却是可商之论。如果我们将民国文学机制改变为"民国文学环境"或者"民国文学生态",那么在民国时期不同时空中不同类型的文学自然会产生于不同的文学环境或生态。 相似文献

This paper reviews recent policy initiatives in England to achieve the closer integration of health and social care. This has been a policy goal of successive UK governments for over 40 years but overall progress has been patchy and limited. The coalition government has a new national framework for integrated care and variety of new policy initiatives including the ‘pioneer’ programme, the introduction of a new pooled budget – the ‘Better Care Fund’ – and a new programme of personal commissioning. Further change is likely as the NHS begins to develop new models of care delivery. There are significant tensions between these very different policy levers and styles of implementation. It is too early to assess their combined impact. Expectations that integration will achieve substantial financial savings are not supported by evidence. Local effort alone will be insufficient to overcome the fundamental differences in entitlement, funding and delivery between the NHS and the social care system.With a national election set to take place in May 2015, all political parties are committed to the integration of health and social care but clear evidence about the best means to achieve it is likely to remain as elusive as ever. 相似文献

Objective
To compare the risk of falls and fall predictors in patients with Parkinson disease (PD), multiple sclerosis (MS), and stroke using the same study design.Design
Multicenter prospective cohort study.Setting
Institutions for physical therapy and rehabilitation.Participants
Patients (N=299) with PD (n=94), MS (n=111), and stroke (n=94) seen for rehabilitation.Interventions
Not applicable.Main Outcome Measures
Functional scales were applied to investigate balance, disability, daily performance, self-confidence with balance, and social integration. Patients were followed for 6 months. Telephone interviews were organized at 2, 4, and 6 months to record falls and fall-related injuries. Incidence ratios, Kaplan-Meier survival curves, and Cox proportional hazards models were used.Results
Of the 299 patients enrolled, 259 had complete follow-up. One hundred and twenty-two patients (47.1%) fell at least once; 82 (31.7%) were recurrent fallers and 44 (17.0%) suffered injuries; and 16%, 32%, and 40% fell at 2, 4, and 6 months. Risk of falls was associated with disease type (PD, MS, and stroke in decreasing order) and confidence with balance (Activities-specific Balance Confidence [ABC] scale). Recurrent fallers were 7%, 15%, and 24% at 2, 4, and 6 months. The risk of recurrent falls was associated with disease type, high educational level, and ABC score. Injured fallers were 3%, 8%, and 12% at 2, 4, and 6 months. The only predictor of falls with injuries was disease type (PD).Conclusions
PD, MS, and stroke carry a high risk of falls. Other predictors include perceived balance confidence and high educational level. 相似文献88.

This study investigated the in vivo formation of engineering cartilage within living or devitalized cartilage discs using reflectance mode confocal microscopy and conventional light microscopy. Pig articular chondrocytes were suspended in fibrin glue and placed between two cartilage discs. Four experimental groups were prepared: in groups 1 and 2, the cell-hydrogel composite was placed between two live or between two devitalized cartilage discs, respectively; in groups 3 and 4, acellular fibrin glue was placed between two live or between two devitalized cartilage discs, respectively. Samples were implanted in the back of nude mice and analyzed after 2, 5, and 8 weeks. Results showed that engineered cartilage seems to grow more homogenously when the cell-seeded gel was placed between devitalized cartilages than when it was placed between live cartilage matrices. Confocal microscopy provides valuable information on the integration of tissue-engineered cartilage with native tissue and could be useful for nondestructive imaging in vivo. 相似文献

The aim of this study was to develop nanofibrous silk substrates for limbal stem cell expansion that can serve as a potential alternative substrate to replace human amniotic membrane. The human limbal stem cell was used to evaluate the biocompatibility of substrates (random and oriented nanofibrous mats, and human amniotic membrane) based on their phenotypic profile, viability, proliferation, and attachment ability. Biocompatibility results indicated that all substrates were highly biocompatible, as limbal stem cells could favorably attach and proliferate on the nanofibrous surfaces. Microscopic figures showed that the human limbal stem cells were firmly anchored to the substrates and were able to retain a normal corneal stem cell phenotype. Microscopic analyses illustrated that cells infiltrated the nanofibers and successfully formed a three-dimensional corneal epithelium, which was viable for 15 days. Immunocytochemistry and real-time PCR results revealed no change in the expression profile of limbal stem cells grown on nanofibrous substrates when compared to those grown on human amniotic membrane. In addition, electrospun nanofibrous silk substrates especially oriented mat provides not only a milieu supporting limbal stem cells expansion, but also serve as a useful alternative carrier for ocular surface tissue engineering and could be used as an alternative substrate to amniotic membrane. 相似文献
