试论《哈克贝利·费恩历险记》的儿童视角

马克·吐温的儿童小说《哈克贝利·费恩历险记》借助儿童尚未受到成人世界人情世故和意识形态浸染的本真生命体验,以哈克天真无邪的眼睛来观察世界,生动地叙述了惊险刺激的故事情节,真实细腻地展现了纯真拙朴的童心世界,进而还原出世界的本来面貌,深化了小说的主题。而促使作家选用儿童视角进行创作的深层心理因素,则是作家的儿童情结与童年生活体验,以及深受圣经文化熏陶的对理想世界潜在的精神需求。     

社会工作视角下大学生志愿服务长效机制构建

当前我国大学生志愿服务大多属于临时或短期的志愿服务活动,缺乏稳定性和持久性,严重制约了大学生志愿服务的深入及可持续发展。大学生志愿服务长效机制的建立,是保证志愿服务可持续发展的重要条件。个人、志愿服务和学校层面因素对大学生长期参与志愿服务产生着不同影响,通过社会工作视角分析发现,健全志愿者选拔与培训体系、导入社工价值理念、建立监督评估激励机制、创建社工义工联动机制等是构建大学生志愿服务长效机制的重要内容。

Copula structure analysis

Summary.  We extend the standard approach of correlation structure analysis for dimension reduction of high dimensional statistical data. The classical assumption of a linear model for the distribution of a random vector is replaced by the weaker assumption of a model for the copula. For elliptical copulas a correlation-like structure remains, but different margins and non-existence of moments are possible. After introducing the new concept and deriving some theoretical results we observe in a simulation study the performance of the estimators: the theoretical asymptotic behaviour of the statistics can be observed even for small sample sizes. Finally, we show our method at work for a financial data set and explain differences between our copula-based approach and the classical approach. Our new method yielear models also.     

FDI Determinants: Case of Romania

Even if the FDI is important for all host countries, for those in the process of transition to a market economy the FDI presence is critical under many respects. Not all transition countries benefited from the very beginning from the FDI presence. Several determinant factors explain the differences. Romania was lagging behind regarding the interest of foreign investors during the first 9–10 years of transition. The situation has improved greatly. The aim of this paper is to identify the main factors determining the evolution in the FDI/GDP (%) as proxy for the FDI evolution. To this end, we used the method of factors analyses. The four resulted determinant factors are: Market size and potential, Reform progress, Business liberalization, and Labor cost. A linear regression model expresses the connections between dependent variable and the four determinant factors. The paper concludes with certain policy implications.

Translation and factor analysis of structural models of Edinburgh Postnatal Depression Scale in Serbian pregnant and postpartum women – Web-based study

BackgroundThe Edinburgh Postnatal Depression Scale (EPDS) is well accepted for detecting symptoms of postnatal depression. The aim of this study was to examine psychometric properties and to evaluate structural models of the Serbian translation of EPDS in pregnant and postpartum women.MethodsThe original English version of the EPDS was translated into Serbian, and checked by means of back-translation. Data were collected via an anonymous online questionnaire posted on a Serbian website devoted to pregnancy topics. The study sample included 201 women (76 pregnant, 125 postpartum). The internal consistency of the scale was measured by Cronbach's α coefficient. Principal component analysis was used to determine scale dimensions while confirmatory factor analysis was used to evaluate model fit.FindingsCronbach α coefficient was 0.84 and 0.83 in pregnant and postpartum women, respectively, which indicated good internal consistency of the Serbian EPDS. Three dimensions of the scale were revealed in both groups of women. Goodness of fit indices described good and excellent model in pregnant and postpartum women, respectively. High level of depression symptoms (score ≥13) was recorded in 27.6% and 24.8% (p > 0.05) of pregnant and postpartum women, respectively. Moderate level of depression symptoms (score 10–12) was recorded in 21.1% and 16.8% (p > 0.05) of pregnant and postpartum women, respectively.ConclusionThe Serbian translation of the EPDS showed good consistency and good model characteristics in pregnant and postpartum women. However, cut-off values, sensitivity and specificity of the scale should be determined in the further studies with more representative samples of women.     

The determinacy of the regression factor score predictor based on continuous parameter estimates from categorical variables

The estimation of population parameters of the continuous common factor model from categorical observed variables is meanwhile regularly performed. It is shown that the formula for the calculation of the determinacy of the regression factor score predictor from the estimated model parameters has to be adapted under these conditions. A method for the calculation of this determinacy from the model parameters of the continuous population factor model based on categorical variables is proposed and evaluated by means of simulated population data. It turns out that using the uncorrected formula can lead to serious overestimation of determinacy for categorical variables.     

大学生社会文化价值观特征分析

一个民族的文化通常有其系统性与适用的价值观,在当今中西文化交融的时代背景下,作为未来栋梁的大学生选择何种价值观体系,一直受到学术界的普遍关注。借鉴相关价值观研究理论,通过因子分析的方法,归纳出大学生的7个价值观类型,并揭示出大学生社会文化价值观的主要特征,即儒家思想中的进取精神得到了大学生的普遍认同,而极端功利与利己主义受到大学生的强烈排斥,大学生的"自我意识"呈现出不统一的特点,实用主义观念在大学生中广泛存在,传统价值观中的"节俭观"和"宿命论"在大学生中受到了严峻的挑战。     

The source of Black-White inequality in early language acquisition: Evidence from Early Head Start

I compare language learning trajectories for Black and White children over the first 3 years of life using data from the Early Head Start Research and Evaluation study (EHSRE) in order to determine the timing and source of divergence in early language skill. Results indicate that that while controlling for racial differences in family background and a measure of the home language environment cannot entirely account for disparities in language acquisition, interactions between age, race and maternal education, and between race and a time-varying measure of the home language environment play a significant role. I show that returns to parental education and the home language environment, in terms of language learning, are higher for White children than their Black peers. Specification checks confirm that these results are robust to alternate definitions of child language and the home language environment, and that no interactions between race, age and any of the other covariates are significant. I discuss possible explanations for these race specific education gradients, including measurement error and test bias. In addition, I address relevant empirical issues in estimating language growth with respect to linguistic inputs and the home language environment.     

我国制造业集聚变迁与全要素生产率增长研究

本文选取我国29个省市区和17个制造行业1990～2009年的面板数据,对相对专业化与相对多样化集聚度进行了计算及变迁分析,利用Malmquist指数测算了全要素生产率的增长,并分析了产业集聚变迁对全要素生产率的影响。结果表明:我国东部地区呈现多样化与专业化集聚均衡发展的特征,而中西部地区则具有相对较高的专业化集聚水平,呈现产业结构单一化与非均衡化;东部地区全要素生产率增长较快,中西部地区相对滞后;相对专业化与多样化集聚对东部、中部与西部地区的影响存在地区差异。基于此,本文提出了加快产业结构调整、实施均衡的区域发展政策和提高经济组织制度绩效的政策建议。
