国内外广告产业统计范围的比较

广告产业统计为广告产业发展的基础性研究课题,同时是政府进行广告产业的财政统计的依据与标准以及实现国际相同产业发展对照的基本标准.我国现行的广告产业统计标准多年来未经调整修正,不能真实反映产业发展实际.文章通过综述国内外相关学术研究,并结合我国现行的《广告业统计报表制度(2012)》、《国民经济行业分类(GB/T4754-2011)》、联合国颁布的《所有经济活动之国际标准行业分类(修订4版)》与《北美产业分类体系(2012)》当中广告产业的统计分类与统计范围,总结我国现行的广告产业统计分类标准存在的主要问题,即产业界定、定位与广告产业现实发展偏离;产业分类方式滞后;产业统计范围狭窄且有重合之处.     

中泰外商直接投资实证研究——以泰国金融结构金融效率为分析对象

在"一带一路"倡议的推动下,泰国作为东盟第三大经济体,以其优越的地理优势和战略地位吸引了不少中国投资者进入泰国投资,而其金融结构与金融效率对中国直接投资有着重大影响.文章通过对金融结构、金融效率及中国在泰国直接投资的分析发现,尽管泰国通货膨胀率、泰国工业生产指数对中国在泰国直接投资没有显著影响,但泰国居民消费指数、泰国商业银行存贷比率、泰国生产价格指数、泰国失业率对中国在泰国直接投资会产生负向影响,而中国与泰国之间的进出口额对中国在泰国直接投资可以产生正向影响.因此,鼓励中国投资者向泰国投资,加大两国贸易合作以及开展两国文化交流,是促进中国和泰国经济进一步发展的有效措施,也是实现互助互利,合作共赢的"一带一路"经济合作目标的有效方法.     

Developmental Latent Patterns of Identification as Mostly Heterosexual Versus Lesbian,Gay, or Bisexual

Scant research exists on the development of mostly heterosexual identity, the largest sexual orientation minority subgroup. We used longitudinal latent class analysis to characterize the patterns of identification with lesbian, gay, bisexual (LGB), or mostly heterosexual identities from ages 12 to 23 in 13,859 youth (57% female) in a U.S. national cohort. Three classes emerged: completely heterosexual (88.2%), mostly heterosexual (9.5%), and LGB (2.4%). LGB class youth generally identified with sexual minority identities by ages 12–17. In contrast, mostly heterosexual class youth identified with sexual minority identities gradually, with steady increases in endorsement starting at the age of 14. Developmental implications of these differential patterns are discussed.     

An empirical assessment of writing and research proficiency in HBCU social work students

ABSTRACT

Lack of proficiency in writing and research among social work students has increasingly concerned social work educators and practitioners. Given the significance of written communication with clients and emphasis on evidence-based practice in the field of social work, it is critical to assess students’ competence in both writing and research. However, deficit-based approaches to assessing writing and research competence have disadvantaged students at historically black colleges and universities (HBCUs). This pilot study aims to assess writing and research proficiency of HBCU master’s of social work (MSW) students through empirical analysis of their capstone papers and surveys from educators to provide implications for developing a writing and research manual for social work programs at HBCUs. Ten capstone papers were randomly selected and qualitatively analyzed; nine faculty and one field supervisor completed the survey, and their respondents were analyzed using cross-case analysis. Analyses of the capstone papers identified two themes for writing and research domains, respectively: (1) weakness in developing statements and lack of knowledge of writing style and (2) plagiarism and lack of understanding of research structure. Moreover, analyses of the surveys revealed four themes regarding assessment of writing and research skills among students struggling with basic writing mechanics, indicating that HBCU MSW students may have potential and capacity for learning, as evidenced by their ideas and critical thinking skills. These findings suggest both teaching- and research-oriented programs could employ the proposed writing and research assessment manual, as well as a writing and research lab/center for improving writing and research skills among their students.     

Mass-mediated surveillance: borders,mobility, and reality television

This article analyzes the social construction of border surveillance and policing in reality-based television. Utilizing content analytic methods to document and decode popular images of borders, mobility, and insecurity, it assesses three programs from Australia, the UK, and the United States. Despite claims of offering accurate and unfiltered depictions, the programs are ideological and provide visions of enforcement that reinforce stereotypes regarding the risks of permeable borders and exonerate intensive regimes of surveillance and securitization. Our findings suggest this occurs in three ways. First, the programs inflate the extent and seriousness of lawlessness associated with cross-border movement. Second, they offer individualistic explanations of crime that cite personal choices and pathologies as determinants. Finally, alongside neglecting their perspectives and interpretations of events, when compared to the reality of official statistics, the programs disproportionately feature suspected offenders as members of marginalized groups. The social and political implications of these findings are discussed.     

Approximate Bayesianity of Frequentist Confidence Intervals for a Binomial Proportion

The well-known Wilson and Agresti–Coull confidence intervals for a binomial proportion p are centered around a Bayesian estimator. Using this as a starting point, similarities between frequentist confidence intervals for proportions and Bayesian credible intervals based on low-informative priors are studied using asymptotic expansions. A Bayesian motivation for a large class of frequentist confidence intervals is provided. It is shown that the likelihood ratio interval for p approximates a Bayesian credible interval based on Kerman’s neutral noninformative conjugate prior up to O(n^{? 1}) in the confidence bounds. For the significance level α ? 0.317, the Bayesian interval based on the Jeffreys’ prior is then shown to be a compromise between the likelihood ratio and Wilson intervals. Supplementary materials for this article are available online.     

The influence function of the optimal bandwidth for kernel density estimation

Theories about the bandwidth of kernel density estimation have been well established by many statisticians. However, the influence function of the bandwidth has not been well investigated. The influence function of the optimal bandwidth that minimizes the mean integrated square error is derived and the asymptotic property of the bandwidth selectors based on the influence function is provided.     

t-Type corrected-loss estimation for error-in-variable model

In this article, we consider a linear model in which the covariates are measured with errors. We propose a t-type corrected-loss estimation of the covariate effect, when the measurement error follows the Laplace distribution. The proposed estimator is asymptotically normal. In practical studies, some outliers that diminish the robustness of the estimation occur. Simulation studies show that the estimators are resistant to vertical outliers and an application of 6-minute walk test is presented to show that the proposed method performs well.     

Grandparents providing care for grandchildren and employment status of grandparents in South Korea

This study examines the association between providing care for grandchildren and the economic status of grandparents, focusing on the employment status. This study asks two questions. First, is providing care for grandchildren related to Korean grandparents’ employment status? Second, are the intensities of providing care for grandchildren related to grandparents’ employment status? In examining these research questions, this study focuses on gender and caregiving intensity. The findings suggest that providing care for grandchildren was associated with Korean grandmothers’ employment status. In addition, there are different relationships between providing care for grandchildren and grandparents’ employment status according to the caregiving intensities.     

人口受教育程度对居民消费的影响研究--基于动态面板分位数回归法

本文采用1996～2015年的31个省市自治区宏观数据,使用动态面板分位数回归方法研究人口受教育程度和居民消费的数量关系。研究结果表明,人口受教育程度对消费有着较为显著的影响,且人口受教育程度对中等消费支出水平的影响略大于高、低消费支出水平的影响,这说明中等消费水平的居民消费受到人口受教育程度的影响更加敏感和有弹性。另外,模型中其他各解释变量系数在各分位数上的差异不大,说明这些影响因素对于不同消费支出水平的消费影响没有太明显差异。
