从构建和谐社会的角度论网络语言对网民价值观念的影响

从构建和谐社会的角度分析网络语言对网民价值观的影响,应通过网络语言自身折射出的价值取向来进行研究,剖析网络语言对人们价值观念的正面影响和负面影响。同时,应着重对其所引起的负面影响提出相应的对策和建议,矫正网络语言对社会公众价值观所造成的偏差。     

事实与权利——占有性质分析

占有制度的法律性质之争由来已久,主要有三种学说:其一为事实说,其二为权利说,其三为权能说。占有的性质应从占有制度的起源及历史发展中探究。古罗马法和日尔曼法因各自经济基础的不同,确立了不同性质的占有制度。它们的立法理念对近代民法的继受产生深远影响,而近代民法对占有性质的不同的立法选择,使占有的性质在发展中日趋明晰。依据现代法学的发展趋势,应当选择将"占有"与"占有权"相分离的路径,区分事实与权利,在此基础上构建占有制度。     

Testosterone level in aging male with different glucose tolerance state and its association with osteocalcin

Objective: To investigate the relationship of testosterone and different glucose tolerance state, and its association with osteocalcin.

Methods: A cross-sectional study was conducted of 1176 males aged 60–97?years who were arranged for an annual regular checkup from March to May 2012 in Chinese PLA general hospital in Beijing.

Results: Individuals categorized as having prediabetes or diabetes were more likely to have lower osteocalcin, testosterone, and SHBG levels compared to those with normal glucose tolerance (p?Conclusions: It showed that serum osteocalcin and TT were closely related with BMI, blood glucose, and TG, which supported the hypothesis that regulation of bone remodeling, energy metabolism, and reproduction are linked.     

Development of Dose‐Response Models to Predict the Relationship for Human Toxoplasma gondii Infection Associated with Meat Consumption

Toxoplasma gondii is a protozoan parasite that is responsible for approximately 24% of deaths attributed to foodborne pathogens in the United States. It is thought that a substantial portion of human T. gondii infections is acquired through the consumption of meats. The dose‐response relationship for human exposures to T. gondii‐infected meat is unknown because no human data are available. The goal of this study was to develop and validate dose‐response models based on animal studies, and to compute scaling factors so that animal‐derived models can predict T. gondii infection in humans. Relevant studies in literature were collected and appropriate studies were selected based on animal species, stage, genotype of T. gondii, and route of infection. Data were pooled and fitted to four sigmoidal‐shaped mathematical models, and model parameters were estimated using maximum likelihood estimation. Data from a mouse study were selected to develop the dose‐response relationship. Exponential and beta‐Poisson models, which predicted similar responses, were selected as reasonable dose‐response models based on their simplicity, biological plausibility, and goodness fit. A confidence interval of the parameter was determined by constructing 10,000 bootstrap samples. Scaling factors were computed by matching the predicted infection cases with the epidemiological data. Mouse‐derived models were validated against data for the dose‐infection relationship in rats. A human dose‐response model was developed as P (d) = 1–exp (–0.0015 × 0.005 × d) or P (d) = 1–(1 + d × 0.003 / 582.414)^?1.479. Both models predict the human response after consuming T. gondii‐infected meats, and provide an enhanced risk characterization in a quantitative microbial risk assessment model for this pathogen.

徐建英:把匠心刻在钱币上

正2015年,北京国际钱币博览会。沈阳造币有限公司展台前,人头攒动,相机频闪。一张铺着红绒布的圆形操作台上,堆满了几十种不同规格的刻刀、凿子以及两块橡皮泥、一个手锤和几幅画稿。一个直径40厘米的半成品圆形钢坯正被牢牢地固定在特制的架子上,在小刀小锤富有节奏感的敲击声中,一点一线间改变着模样。不知过了多久,徐建英缓缓直起身,轻而长地吐了口气。他摘下头上的放大镜,习惯性地微皱着眉头,对刚刚雕刻的作品细细端详起     

The Impact of Core Self-evaluations on Job Satisfaction: The Mediator Role of Career Commitment

The present study investigated the impact of core self-evaluations on job satisfaction, with a primary focus on confirmation of the mediator role of career commitment. Three hundred and twelve male soldiers completed the Core Self-Evaluations Scale, the Minnesota Satisfaction Questionnaire, and The Chinese Career Commitment Scale. The results revealed that both career commitment and core self-evaluations were significantly correlated with job satisfaction. Structural equation modeling indicated that career commitment partially mediated the relationship between core self-evaluations and job satisfaction. The final model also revealed a significant path from core self-evaluations to job satisfaction through career commitment. The findings extended prior reports and shed light on how core self-evaluations influence job satisfaction; this provides valuable evidence on promoting job satisfaction in non-commercial organizations.     

Robust Contracts in Continuous Time

We study a continuous‐time contracting problem under hidden action, where the principal has ambiguous beliefs about the project cash flows. The principal designs a robust contract that maximizes his utility under the worst‐case scenario subject to the agent's incentive and participation constraints. Robustness generates endogenous belief heterogeneity and induces a tradeoff between incentives and ambiguity sharing so that the incentive constraint does not always bind. We implement the optimal contract by cash reserves, debt, and equity. In addition to receiving ordinary dividends when cash reserves reach a threshold, outside equity holders also receive special dividends or inject cash in the cash reserves to hedge against model uncertainty and smooth dividends. The equity premium and the credit yield spread generated by ambiguity aversion are state dependent and high for distressed firms with low cash reserves.
