数字营销传播背景下的新型社会形态研究

随着数字营销传播的发展,社会形态发生了巨大的改变.数字营销传播的载体改变了传统的生活方式,让消费和传播变得更加精准,各种各样私人化的定制服务满足了人们个性化的需求.这种新型的营销传播方式让消费者在市场中占据了主导位置.数字技术在改变生活方式的同时,也改变着人们的认知系统和价值观念.经过数字营销传播的洗礼,社会结构重新部落化,沟通变得更加平等.行业之间开始融合,不同领域的行业边界变得模糊不清.以往的营销传播理念已无法满足当今大变革时代的需求,新型社会形态需要全新的营销传播理论与之相对应.

Temporal Disaggregation: Methods,Information Loss,and Diagnostics

This research provides a generalized framework to disaggregate lower-frequency time series and evaluate the disaggregation performance. The proposed framework combines two models in separate stages: a linear regression model to exploit related independent variables in the first stage and a state–space model to disaggregate the residual from the regression in the second stage. For the purpose of providing a set of practical criteria for assessing the disaggregation performance, we measure the information loss that occurs during temporal aggregation while examining what effects take place when aggregating data. To validate the proposed framework, we implement Monte Carlo simulations and provide two empirical studies. Supplementary materials for this article are available online.     

An exploratory data analysis in scale-space for interval-valued data

We propose an exploratory data analysis approach when data are observed as intervals in a nonparametric regression setting. The interval-valued data contain richer information than single-valued data in the sense that they provide both center and range information of the underlying structure. Conventionally, these two attributes have been studied separately as traditional tools can be readily used for single-valued data analysis. We propose a unified data analysis tool that attempts to capture the relationship between response and covariate by simultaneously accounting for variability present in the data. It utilizes a kernel smoothing approach, which is conducted in scale-space so that it considers a wide range of smoothing parameters rather than selecting an optimal value. It also visually summarizes the significance of trends in the data as a color map across multiple locations and scales. We demonstrate its effectiveness as an exploratory data analysis tool for interval-valued data using simulated and real examples.

Development and evaluation of the physical activity questionnaire for elderly Japanese: the Nakanojo study

The Physical Activity Questionnaire for Elderly Japanese (PAQ-EJ) is a self-administered physical activity questionnaire for elderly Japanese; the authors report here on its repeatability and direct and indirect validity. Reliability was assessed by repeat administration after 1 month. Direct validation was based on accelerometer data collected every 4 s for 1 month in 147 individuals age 65-85 years. Indirect validation against a 10-item Barthel index (activities of daily living [ADL]) was completed in 3,084 individuals age 65-99 years. The test-retest coefficient was high (r = .64-.71). Total and subtotal scores for lower (transportation, housework, and labor) and higher intensity activities (exercise/sports) were significantly correlated with step counts and durations of physical activity <3 and >or=3 METs (r = .41, .28, .53), respectively. Controlling for age and ADL, scores for transportation, exercise/sports, and labor were greater in men, but women performed more housework. Sex- and ADL- or age-adjusted PAQ-EJ scores were significantly lower in older and dependent people. PAQ-EJ repeatability and validity seem comparable to those of instruments used in Western epidemiological studies.     

试论清朝初期对侗族地区土司的管理

清朝初期,清政府十分重视对侗族地区土司的管理。广加招徕,准予承袭,制定并施行一系列严密的管理措施。这对于稳定和巩固西南边疆,起了重要的作用。随着侗族地区土司制度的腐朽,其弊端日渐显露,为雍正时期清政府于此进行改土归流提供了条件。     

The Contingent-Claims Approach to Investment Decisions*

This paper presents a contingent-claims approach to project valuation when capital expenditures are made sequentially over time. It focuses on an important facet of sequential investment projects that the firm can undertake—or pass up projects—as more information becomes available. The contingent-claims approach takes account of this important feature of firms' investment decision process, whereas the traditional capital budgeting procedure does not. Since the traditional method does not reflect the options nature of investment opportunities, it underestimates the value of sequential investment projects. As a result, a naive implementation of the traditional capital budgeting procedure could result in rejecting profitable projects. The extent of undervaluation associated with the traditional capital budgeting procedure is greater when the correlation between the random component of the future asset value and that of the required capital expenditure is smaller and/or when the growth rate of the required capital expenditure is higher.     

传统藏戏的审美张力分析

传统藏戏将教化性和审美性融合统一,形成了具有无限延展的审美空间,被藏民族一代代接受和传承。传统藏戏的多种元素彼此之间相互对抗、冲突和矛盾,形成具有张力的审美空间和强大的审美冲击力,使接受者产生共鸣,在艺术的审美中获得精神的洗礼。在传统藏戏中,主客体巨大反差产生崇高美,体现出藏民不屈的超越精神,以及克服和战胜恐惧后的心灵慰藉和平静;传统藏戏采用佛教逻辑叙述故事,集中体现藏民的人生姿态和精神信仰以及对于真善美的认知和追求,凸显世俗的人性美;藏戏以美的艺术形式和程序化的艺术表演再现普通大众的味与情,形成独具特色的审美情感和审美趣味,最终达到宗教教化的目的;藏戏中戏师的理性讲述与演员的感性表演形成对照,让受众游走于理性与感性之间,对于人物与情节有了更加深刻的感性认知和理性反思;藏戏重复与回环的情节设置使故事情节发展更曲折,人物形象更丰满,主题思想更鲜明,形成了复调之美。     

Pathways from workplace flexibility to turnover intention: Role of work–family conflict,family–work conflict,and job satisfaction

This study examined the prevalence of workplace flexibility and the mechanisms that allow workplace flexibility to influence turnover intentions through work–family and family–work conflicts and job satisfaction among low‐wage workers in South Korea. Participants included 250 low‐wage workers whose monthly salary was less than 2 million Korean won (approx. $1,900). The study results indicate that low‐wage workers have limited access to workplace flexibility and that workplace flexibility plays a significant protective role in reducing their turnover intention, indirectly by decreasing work–family conflicts and enhancing job satisfaction. This article also discusses the implications of these findings for labor policy and social work practice.
