资源型城市女大学生就业问题分析——以阜新市女大学生就业情况为例

针对资源型城市女大学生就业问题,结合阜新市女大学生就业的基本情况,分析了女大学生就业期望值过高、缺乏实际技能与经验等个人就业意愿和技能与劳动力市场机会及需求不匹配的普适性障碍,分析了由自身性别原因带来的个性障碍,提出了转变就业观念、降低心理预期、制定正确的职业生涯规划、加强就业指导、学校和企业共同建立带薪实习机制、注重提高自身素质等建议。     

贸易中的知识产权壁垒与应对战略

贸易壁垒总体上分为关税措施和非关税措施.在关税措施受到世界贸易组织严格限制的条件下,发达国家则转向使用富有弹性的非关税措施,特别是知识产权措施,制造贸易障碍,为自己谋取不当利益.这引起了大多数发展中国家的反对和世界贸易组织的高度关注.中国作为最大的发展中国家也深受贸易壁垒之害.知识产权壁垒已经成为我国贸易发展的主要障碍之一.发达国家知识产权壁垒有着深刻的战略背景,需要我们从战略上加以应对.构建和实施我国的知识产权战略体系既是当务之急,也是一项长期艰巨的任务.     

技术性贸易壁垒对我国机电产品出口的影响

经济全球化和贸易自由化的发展使得关税壁垒和传统非关税壁垒的影响逐渐减弱，技术性贸易壁垒越来越多地被发达国家利用，在一定程度上阻碍了国际贸易的发展。机电产品作为我国的主要出口产品，自然而然地成为受技术性贸易壁垒影响最为严重的产品之一。利用引力模型检验技术性贸易壁垒对我国机电产品出口的影响，根据检验结果找出原因，并提出相应对策。     

大连水产品出口现状、问题与对策研究

在新一轮东北振兴的背景下,大连作为沿海经济带的龙头,如何通过发展海洋经济,建设渔业生产基地,建立水产品国际贸易中心,从而提高水产品出口的竞争力,为辽宁经济的新一轮振兴做出贡献是一个关键和值得研究的问题。目前,大连水产品出口贸易已具有相当规模,然而近年来,水产品出口贸易发展遇到了贸易环境恶化、出口市场过度集中和水产品生产技术滞后等诸多阻碍。这些问题不解决,其水产品出口就不会有大的提高,就难以持续发展,因此,对于大连水产品出口问题的研究有重要的现实意义。     

冲不破的樊篱--用社会性别差异视点解读林芙美子的《浮云》

用社会性别差异的视点,从女性追求自我,男女性别的非对称性出发,通过主人公雪子的进京、离京、回京、再离京的4次移动,分析了其漂泊、堕落的背景、对父权制度的抗争和挑战以及她追求自由、性爱的深层心理, 从而证明性别差异化的社会制度是造成雪子人生失败的根源。     

Bayesian analysis of single-molecule experimental data

Summary.  Recent advances in experimental technologies allow scientists to follow biochemical processes on a single-molecule basis, which provides much richer information about chemical dynamics than traditional ensemble-averaged experiments but also raises many new statistical challenges. The paper provides the first likelihood-based statistical analysis of the single-molecule fluorescence lifetime experiment designed to probe the conformational dynamics of a single deoxyribonucleic acid (DNA) hairpin molecule. The conformational change is initially treated as a continuous time two-state Markov chain, which is not observable and must be inferred from changes in photon emissions. This model is further complicated by unobserved molecular Brownian diffusions. Beyond the simple two-state model, a competing model that models the energy barrier between the two states of the DNA hairpin as an Ornstein–Uhlenbeck process has been suggested in the literature. We first derive the likelihood function of the simple two-state model and then generalize the method to handle complications such as unobserved molecular diffusions and the fluctuating energy barrier. The data augmentation technique and Markov chain Monte Carlo methods are developed to sample from the posterior distribution desired. The Bayes factor calculation and posterior estimates of relevant parameters indicate that the fluctuating barrier model fits the data better than the simple two-state model.

Factor Analysis of Barriers to Treatment for Problem Gambling

Attitudes toward problem gambling treatment were investigated in a telephone survey of 1,203 persons in Central Queensland Australia (598 women and 605 men, mean age = 45.8 years). Survey items were compiled from existing substance abuse questionnaires (Center on Alcoholism, Substance Abuse and Addictions, 1995; Sobell et al., 1991). An exploratory factor analysis identified five potential barriers to treatment, including: availability, stigma, cost, uncertainty, and avoidance. Relative to those with few problems, respondents who had numerous gambling problems were more concerned about treatment costs, and the availability and effectiveness of treatment. In addition to the above concerns, older persons more often negatively judged the treatment seeker. In contrast, educated respondents had generally more positive attitudes towards problem gamblers and treatment seeking.
