大学生“自我”迷失现状剖析与引导

"自我"概念存在着"主体自我"与"客体自我"、"现实自我"与"理想自我"的冲突,不能妥善解决有可能导致"自我"迷失现象.大学生"自我"迷失现状既存在着不尊重爱惜生命、自毁或攻击他人危害社会的极端案例,但更多的是存在着自卑、孤独、焦虑、抑郁、厌学等一般情况.大学生"自我"冲突的原因在于"自我实现"受干扰,遏障碍与被积极关注的缺失.对策在于要帮助大学生认识自我,建立自我一致性;发现自我,秉持特立独行;发展自我,满足关注需要;完善自我,实现和谐统一.     

文化缺失:汉语古诗词英译之文化维度

由于中西方文化背景的极大差异,这就注定了汉英诗歌翻译时必然会出现文化缺失:归化缺失;删译缺失;意译典故造成文化的缺失;不同的文化传统造成文化接受缺失。这也就需要译者在认真读懂原稿的基础上懂得变通,抓住文化内涵的核心,由诗词的表层结构深入到其深层结构,尽力展现其"意"的传神和生动,从而在更高的层面上实现文化的沟通。     

"士"与战国时期的传播艺术

在社会性质由奴隶制向封建制转化的春秋战国时期,"士"在政治、经济、军事、外交活动中充任着重要的角色,逐渐取代周代以前的"巫史",成为当时社会传播活动的主体,他们通过游说诸侯、聚徒讲学、记言记事等方式,向诸侯、学生及大众传播自己的思想观念,而这种种不同的传播方式又展示出他们在论辩艺术、教育艺术和叙事艺术方面的高超智慧.     

Weight Loss Practices and Body Weight Perceptions Among US College Students

Objective: The authors assessed associations between body weight perception and weight loss strategies. Participants: They randomly selected male and female college students (N = 38,204). Methods: The authors conducted a secondary data analysis of the rates of weight loss strategies and body weight perception among students who completed the National College Health Assessment survey. Results: Half of respondents (50%) were trying to lose weight, although only 28% of students were overweight or obese. Also, 12% of respondents had inaccurate body weight perception. Women and men with inaccurate body weight perception were significantly more likely to engage in inappropriate weight loss strategies than were those with accurate body weight perception. Of all students attempting to lose weight, 38% used both diet and exercise. Conclusions: These data show that college students are interested in weight loss and that body weight perception plays an important role in the desire to lose weight.

本文简要叙述了红磷形成烟雾的过程及性质,并用 Mie 理论计算了不同温度条件下红磷烟雾对10.6μm 激光的质量消化系数α_c 和质量散射系数α。理论计算与实验测得的α_c 有较好的一致性。     

论保留保险代位权制度

保险代位权是保险法历史上一项古老的制度,近来一些学者对其存在的合理性、必要性提出了质疑,甚至主张废除这一制度,这种观点有悖于保险代位权存在和发展的历史规律,尤其不符合中国现阶段经济社会发展的现实。针对废除保险代位权的理由,从保险代位权存在的理论基础、现实状况、价值功能等方面对其存在的合理性、必要性进行了论证。     

Censored Kullback-Leibler Information and Goodness-of-Fit Test with Type II Censored Data

The Kulback-Leibler information has been considered for establishing goodness-of-fit test statistics, which have been shown to perform very well (Arizono & Ohta, 1989; Ebrahimi et al., 1992, etc). In this paper, we propose censored Kullback-Leibler information to generalize the discussion of the Kullback-Leibler information to the censored case. Then we establish a goodness-of-fit test statistic based on the censored Kullback-Leibler information with the type 2 censored data, and compare the test statistics with some existing test statistics for the exponential and normal distributions.     

Comparison of estimators of the location parameter using pitman's closeness criterion

Necessary and sufficient conditions for a linear estimator to dominate another linear estimator of a location parameter under the Pitman's criterion of comparison are discussed. Consequently it is demonstrated that a linear biased estimator can not dominate a linear unbiased estimator under Pitman's criterion and that the sample mean is the Closest Linear Unbiased Estimator (CLUE). It is also shown that the ridge regression estimator with a known biasing constant can not dominate the ordinary least squares estimator. If an estimator δdominates an estimator δin the average loss sense then sufficient conditions are obtained under which δis also preferred over δunder Pitman's criterion. Further we obtain sufficient conditions under which preference under the Pitman's criterion will lead to preference under the mean squared error sense.     

Bayesian estimation for the Pareto income distribution

The Bayes estimators of the Gini index, the mean income and the proportion of the population living below a prescribed income level are obtained in this paper on the basis of censored income data from a pareto income distribution. The said estimators are obtained under the assumptions of a two-parameter exponential prior distribution and the usual squared error loss function. This work is also extended to the case when the income data are grouped and the exact incomes for the individuals in the population are not available. The method for the assessment of the hyperparameters is also outlined. Finally, the results are generalized for the doubly truncated gamma prior distribution. Now deceased.
