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.     

Who is Jobless? A Comparison of Joblessness in Rural and Urban Areas in China

Since market‐oriented economic reform was launched in China in the 1980s, unemployment has been recognized by the government. This paper focuses on the differences in joblessness in rural and urban areas between rural migrant workers, peasants, and urban citizens. The results indicate that people in rural areas frequently lose their jobs, which differs from the traditional perception. There is a significantly lower jobless rate in urban areas. In contrast to the results of previous studies, the employment situation of rural migrant workers is closer to urban citizens rather than peasants. Logistic regression results show that the elderly, women, and less educated citizens have a higher likelihood of joblessness, both in urban and rural areas. Minorities have a lower likelihood of joblessness in rural areas and a higher likelihood in urban areas. Chinese Communist Party members and people without dependent children have a lower likelihood of joblessness in urban areas.     

Who needs Cantonese,who speaks? Whispers across mountains,delta, and waterfronts

This essay digs into the ‘dirtiness’ of cultural studies to prioritize praxis, or as the way my mountain folks collect summer lotus: putting our feet in the muddy water, and finding ways to get the stems underneath the smooth leaves. Using Cantoneseness as a case to locate such ‘dirtiness’, I draw on personal/familial histories as well as research projects to tell how conjunctures of Cantoneseness are politically and unevenly lived. This complex journey travels roughly from my childhood in the Yuebei mountains of northern Guangdong through my teenage and early adult years in the Pearl River Delta (PRD) to my current location as a temporary resident in the East Pacific port of Vancouver. I selectively emphasize and speak on three different locations: first, the rural inland Cantonese location of Yuebei mountains – the borderland and hinterland experiences of my family and myself living what the mountains would offer and how these have changed; second, the industrial superior Cantonese location of PRD in Shenzhen and Guangzhou – my personal experiences and identities as a migrant youth, combined with a case study including interviews with migrant peasant-workers and their children; and third, the western transnational Cantonese location of East Pacific waterfronts in Vancouver and Richmond – my personal engagement with social activism as an ethnicized, international student, combined with a narrative study including interviews with social activists with different Cantoneseness and migration routes. While this mix of whispers speaks in its own way towards using cultural studies with more seriously (global) space-sensitive and (social justice) praxis-sensitive approaches, the primary focus is more modestly on my autobiographical accounts and research efforts as a specific case: to show some strategic locations of ‘Cantonescape’ on the one hand, and to invite wider conversations around cultural-spatial politics on the other.     

China’s modern image – contemporary Chinese art

Abstract

As a worldwide cultural phenomenon, contemporary art in China has not only been used as a diplomatic language but also a reflection of contemporary Chinese culture. Contemporary Chinese art, as an emerging field to display China’s global role, provides an important perspective to study China’s self-position in global relations, China’s diplomacy in exercising its soft power, contemporary Chinese culture, and the reinvention of China’s cultural/national identity in post-Mao China. Using the 2000 Shanghai Biennale and the Chinese pavilion at the 54th Venice Biennale as case studies, this article investigates how the fluid construct of Chineseness is successfully promoted and demonstrated through the government’s support of contemporary Chinese art.     

An Examination of School Counselors’ Competency Working with Lesbian,Gay and Bisexual and Transgender (LGBT) Students

This study aims to investigate school counselors’ competency level in working with lesbian, gay, bisexual, transgender (LGBT) youth. Using a sample of 125 school counselors who are currently practicing in schools, this study found school counselors perceived themselves with very low competency levels. Spearman's rho correlation results indicated that only three demographic variables were significantly correlated with school counselors’ self-perceived competency level: sexual orientation, whether having received any postmasters trainings and geographic regions. Counselors identifying as nonheterosexual, those who received postmasters trainings or workshops, and those who reside in the West tend to have a higher self-perceived competency working with youth identifying as LGBT.

Unified Inference for Sparse and Dense Longitudinal Data in Time‐varying Coefficient Models

Time‐varying coefficient models are widely used in longitudinal data analysis. These models allow the effects of predictors on response to vary over time. In this article, we consider a mixed‐effects time‐varying coefficient model to account for the within subject correlation for longitudinal data. We show that when kernel smoothing is used to estimate the smooth functions in time‐varying coefficient models for sparse or dense longitudinal data, the asymptotic results of these two situations are essentially different. Therefore, a subjective choice between the sparse and dense cases might lead to erroneous conclusions for statistical inference. In order to solve this problem, we establish a unified self‐normalized central limit theorem, based on which a unified inference is proposed without deciding whether the data are sparse or dense. The effectiveness of the proposed unified inference is demonstrated through a simulation study and an analysis of Baltimore MACS data.     

Precise large deviations for φ-mixing and UND random variables with long-tailed distributions

In this paper, we investigate the precise large deviations for sums of φ-mixing and UND random variables with long-tailed distributions. The asymptotic relations for non random sum and random sum of random variables with long-tailed distributions are obtained.     

矛盾性追加评论对感知有用性的影响效应研究

 随着在线评论机制的完善,各大网络购物平台设置了追加评论的功能,消费者可在初次评论后一定时间段内针对同一产品再次评论。目前追加评论逐渐引起学者们的广泛关注,已有关于含追加的在线评论研究中,大多是针对含追加评论与未追加评论之间、含追加评论中一致性追加评论与矛盾性追加评论之间的感知有用性差异进行比较研究,较少研究分析矛盾性追加评论之间,即初次评论与追加评论情感方向不一致的情况下含追加评论的感知有用性差异。        将矛盾性追加评论分为初次评论为正、追加评论为负和初次评论为负、追加评论为正两种情况,基于归因理论和精细加工可能性模型的视角,探讨矛盾性追加评论对感知有用性差异的影响效应以及不同产品卷入度对矛盾性追加评论感知有用性差异的调节作用。实验均以大学生为样本,从天猫商城真实的评论环境中获取的在线追加评论作为实验数据,采用曼-惠特尼秩和检验和Wilcoxon符号秩检验两种非参数检验方法进行数据分析。        研究结果表明,①在矛盾性追加评论中,初次评论为正、追加评论为负的含追加评论感知有用性显著高于初次评论为负、追加评论为正的在线评论;②产品卷入度对矛盾性追加评论感知有用性差异具有调节作用,对于高卷入度产品而言,正-负追加组和负-正追加组感知有用性差异显著;对于低卷入度产品而言,这种差异不显著。        从理论上讲,研究结论进一步完善了含追加在线评论的研究框架,并引入了产品卷入度这一调节变量,解释了人们对矛盾性信息感知的差异。研究结论还具有一定的实践指导意义,由于消费者更加关注正-负追加组的在线评论,企业应采取措施降低负面追加评论对产品的影响。
