本土品牌逆袭与消费者偏好逆转的纵向扎根研究

  如今的中国市场，诸多行业本土品牌崛起甚至逆袭，消费者对全球品牌与本土品牌的偏好相应逆转。已有研究较为全面地揭示了全球品牌和本土品牌偏好的驱动因素，但本土品牌逆袭过程中全球品牌与本土品牌偏好的驱动因素是否相同、本土品牌逆袭与消费者偏好逆转的互动影响路径是怎样的，对这些问题缺乏探讨。         在梳理相关研究的基础上，以手机行业为研究对象，采用扎根理论的研究方法，通过对网络讨论数据的初始编码、聚焦编码和理论编码，首先研究全球品牌与本土品牌偏好的驱动因素的异同，然后结合对讨论数据的纵向统计结果，研究本土品牌逆袭过程中品牌逆袭与消费者偏好逆转的互动影响路径。         研究结果表明，本土品牌逆袭中，全球品牌与本土品牌偏好的驱动因素模型具有相似的结构，功能价值和社会价值的测量受个人因素调节而影响消费者偏好，但测量功能价值或社会价值的具体因素在全球品牌与本土品牌中存在差异。品牌逆袭有助于提升综合国力、促进消费者成熟，进而驱动消费者偏好逆转；消费者偏好逆转则通过反馈路径帮助品牌进一步逆袭。具体的，消费者对产品特质更加重视，全球品牌的原产国效应和符号价值表现力减弱，本土品牌的口碑效应和符号价值表现力增强，同时消费者的民族主义增强而爱国绑架感减弱，这些因素通过感知价值带来消费者偏好逆转。综合而言，本土品牌逆袭和消费者偏好逆转是互动提升的关系。         研究结果丰富了全球品牌和本土品牌的相关研究，为全球品牌和本土品牌的建设提供了实践启示。产品特质是影响消费者偏好的主要因素，并对其他驱动因素有支撑作用。所以全球品牌和本土品牌都要重视产品的创新和研发，还要根据各驱动因素的变化调整其营销策略。     

属性集容量确定的夹挤式测度模式及其推算模型

迄今，为解决多属性偏好关联决策属性集容量判断指数复杂性难题所提出的λ模糊测度模式与k-可加模糊测度模式，以及建构在它们之上的属性集容量确定的推算模型，尚存在着适用性差的技术不足。为此，以平衡容量判断的可操作性和容量推算的准确性为视角，提出了一种新容量测度模式，即关于容量判断与推算的夹挤式测度模式，并在此基础上通过引入决策者较易判断给出的容量序信息构建了相应的容量推算模型。基于数值模拟的对比分析表明：新模式不仅在应用可行性上高于k-可加模糊测度模式，而且从容量推算的准确性上看也明显优于λ模糊测度模式和k-可加模糊测度模式，因而对实际决策具有更强的适用性。     

Attitudes of social work students towards older people

Demographic ageing is a challenge for many countries. Even though Turkey has a relatively younger demographic composition, the proportion of the older people (65+) within the population is rapidly increasing. Within this framework, older people are becoming more important clients for both social work students and social workers in Turkey. This study aims to reveal the attitudes of social work students towards older people and determine the various factors that affect their views on older persons. In the scope of the project, Kogan's Attitude Towards Old People Scale was applied to 419 social work undergraduate students at a university located in Central Anatolia. The findings showed that social work students scored a mean of 130.96 and they generally had positive attitudes towards older people. The correlation between year of study, gender and age was not statistically significant. However, having lived mostly in urban areas was positively correlated with the mean Kogan scores and this finding was found to be statistically significant. Exposure to personal contact with older people at both the personal and professional levels was influential in shaping attitudes about the older people.     

Multiplicative consistency analysis for interval fuzzy preference relations: A comparative study

To examine the multiplicative consistency of interval fuzzy preference relations (IFPRs), this paper first analyzes the limitations associated with the previous consistency concepts. Accordingly, a new consistency concept is defined that is an extension of the crisp case and overcomes limitations in the previous concepts. Next, a linear programming model to judge the consistency of IFPRs is constructed, and an approach to derive multiplicative consistent IFPRs is introduced. Furthermore, goal-programming models to determine missing values in an incomplete IFPR are constructed that have the highest consistent level with respect to known values. Moreover, a multiplicative consistency and consensus based method for group decision making with IFPRs is developed that can address incomplete and inconsistent cases. Finally, two practical decision-making problems are offered to demonstrate the feasibility and efficiency of the new method, and an analysis of a numerical and theoretical comparison with several related methods is performed.     

The older the bolder: Does relative age among peers influence children’s preference for competition?

Having been relatively old at school tends to have a long lasting positive effect on professional achievement, in particular in competitive environments (sports, politics). We investigate the roots of this pattern and study whether the relative age position of children at school plays a role in shaping their preference for competition. We run a controlled experiment in high schools across two states in Australia. Our participants are students who are the very oldest or very youngest in their classroom. We elicit their preference for competition using the Niederle and Vesterlund (2007) task and find evidence of an effect of relative age. This effect is concentrated on male students. We find no differences in self-confidence, and risk attitudes between relatively old and young students. These results suggest that the observed pattern may come from pure preference for competition.     

生产者货币计价决定因素的实证研究

利用12个发达国家和发展中国家的非平衡面板样本数据,对微观、宏观和其他因素对生产者货币计价(PCP)的影响进行实证研究,指出经济规模、市场份额、金融市场的发达程度、币值的对内稳定性和产品差异化程度是最主要的影响因素,而出口商的谈判能力、币值的对外稳定性等因素也对PCP的选择有一定影响。根据实证检验结果,对人民币作为贸易计价货币的条件进行评估,发现其优势在于我国的经济规模、出口商的市场份额及其谈判能力以及人民币汇率的相对稳定性; 劣势在于相对落后的金融市场、不可预期性较大的通货膨胀水平以及产品的差异化程度。     

Stochastic comparisons between extreme order statistics from scale models

Stochastic ordering relations between extreme order statistics from exponential, Weibull and gamma distributions have been studied extensively by many researchers in recent years. In this work, we obtain various ordering results for the comparisons of two extreme order statistics from scale models when one set of scale parameters majorizes the other. The new results obtained here are applied when the baseline distributions are exponentiated Weibull or generalized gamma distributions. In this way, we generalize and extend some results established recently in the literature.     

当代女性择偶标准及其影响因素研究--基于365则女性征婚启事的内容分析

对2005年至2014年间刊登于五本杂志上的365则女性征婚启事进行内容分析和统计检验，发现在女性征婚者的自我陈述和择偶要求中，既有较为稳定的传统标准，也存在一些时代变化。女性自身的职业和文化程度提及率较高，择偶标准中道德品质和个性、个人素质等受到了更多关注。在社会资源方面，隐性的资源更被强调，择偶标准呈现多元化取向。在更年轻和文化程度更高的女性中，体现出了更具现代性的择偶标准。有婚史和有孩子的女性则更多地关注一些现实性的标准。     

Quantile Regression for Location‐Scale Time Series Models with Conditional Heteroscedasticity

This paper considers quantile regression for a wide class of time series models including autoregressive and moving average (ARMA) models with asymmetric generalized autoregressive conditional heteroscedasticity errors. The classical mean‐variance models are reinterpreted as conditional location‐scale models so that the quantile regression method can be naturally geared into the considered models. The consistency and asymptotic normality of the quantile regression estimator is established in location‐scale time series models under mild conditions. In the application of this result to ARMA‐generalized autoregressive conditional heteroscedasticity models, more primitive conditions are deduced to obtain the asymptotic properties. For illustration, a simulation study and a real data analysis are provided.     

古典家具的“分”与“融”对现代设计的启示

弃“席”而“坐”居住方式的重大变革是中国古典家具“分”与“融”的主要根源。以楚式家具、宋式家具、明清家具为代表，在矮型家具向高型家具的演变进程中，家具突显出在功能、阶级风格上的“分离”和以消除与居住方式的分歧为目的的式样上的“融合”。其中的“分”与“融”，对现代设计中如何把握产品功能、设计元素、品牌文化的“取”“舍”尺度问题具有重要启示。
