Consumer receptiveness to international retail expansion: a cross-cultural study of perceptions of social and economic influence of foreign retailers

Guided by the work of Samiee (1993 Samiee, S.1993. “Retailing and Channel Considerations in Developing Countries: A Review and Research Propositions.” Journal of Business Research27 (2): 103–129. doi:10.1016/0148-2963(93)90018-K.[Crossref], [Web of Science ®] , [Google Scholar]. Journal of Business Research, 27 (2): 103–129), Sakarya, Eckman, and Hyllegard (2007 Sakarya, S., M.Eckman, and K.Hyllegard. 2007. “Market Selection for International Expansion.” International Marketing Review24 (2): 208–238. doi:10.1108/02651330710741820.[Crossref], [Web of Science ®] , [Google Scholar]. International Marketing Review, 24 (2): 208–238), and Alexander et al. (2010 Alexander, N., A. M.Doherty, J.

International Journal of Retail & Distribution Management, 38 (3): 160–172), a cross-cultural analysis was undertaken to examine consumer receptiveness to domestic market entry by foreign apparel specialty retailers. More specifically, this study explored differences in consumers' perceptions of the influence of foreign apparel specialty retailers on social, cultural, and economic development across three countries: Spain, Turkey, and the USA. Consumer receptiveness was measured as beliefs about the social and economic influence of foreign retailers and perceptions of retailers' brand characteristics and offerings. An intercept survey of 1233 apparel shoppers was conducted in major metropolitan shopping areas in all three countries. MANOVA revealed that Spanish consumers were least concerned about urban growth associated with foreign retailers and least likely to perceive positive employment/business opportunities and socio-cultural well-being from the presence of foreign retailers. Turkish consumers held the strongest perceptions regarding the influence of foreign retailers on urban growth. Paired sample t-tests revealed that Turkish consumers, when compared with Spanish consumers, evaluated U.S. retailers' offerings more positively and were more receptive to the entry of U.S. retailers into their domestic markets. Results of regression analyses indicated that Spanish and Turkish consumers' beliefs about retail brand characteristics and the socio-cultural and economic influence of foreign retailers positively predicted consumers' receptiveness, whereas age negatively influenced receptiveness. Differences in perceptions among Spanish, Turkish, and U.S. consumers may be attributed to the varying levels of economic development among the three countries as well as to the countries' differing policies concerning foreign retailers. Findings provide a basis for the development of a measure of consumer receptiveness to international retail expansion.     

Consumer vulnerability and complaint handling: Challenges,opportunities and dispute system design

Effectively designed complaint handling systems play a key role in enabling vulnerable consumers to complain and obtain redress. This article examines current research into consumer vulnerability, highlighting its multidimensional and expansive nature. Contemporary understandings of consumer vulnerability recognize that the interaction between a wide range of market and consumer characteristics can combine to place any individual at risk of vulnerability. While this broad definition of consumer vulnerability reflects the complex reality of consumers’ experiences, it poses a key challenge for designers of complaint handling systems: how can they identify and respond to an issue which can potentially affect everyone? Drawing on current research and practice in the United Kingdom and Australia, the article analyses the impact of consumer vulnerability on third party dispute resolution schemes and considers the role these complaint handling organizations can play in supporting their complainants. Third party complaint handling organizations, including a range of Alternative Dispute Resolution services such as ombudsman organizations, can play a key role in increasing access to justice for vulnerable consumer groups and provide specific assistance for individual complainants during the process. It is an opportune time to review whether the needs of consumers at risk of vulnerability are being met within complaint processes and the extent to which third party complaint handlers support those who are most vulnerable to seek redress. Empowering vulnerable consumers to complain presents specific challenges. The article discusses the application of a new model of consumer dispute system design to show how complaint handling organizations can meet the needs of the most vulnerable consumers throughout the process.     

Influencing Consumer Responses to Highly Aesthetic Products: The Role of Mindsets

Companies often use aesthetics or salient visual attributes to differentiate their products from those of their competitors and to appeal to customers. However, consumers may make unfavorable inferences about highly aesthetic products due to concerns about the products’ functionality. To address the issue of how retailers can most effectively engage in the deployment and promotion of product aesthetics, the present research proposes that consumers will respond more favorably (i.e., enhanced choice of product, enhanced product and advertisement evaluations, and a heightened willingness to pay) to a highly aesthetic product when they are in an abstract, rather than a concrete, mindset. Five studies using multiple product categories and applying various mindset manipulations provide convergent evidence to support the proposed hypothesis. The findings hold true for utilitarian, but not hedonic, products, and the focus of attention on product functionality accounts for the results. With the insight that the mindset consumers are in is critical in determining their response to highly aesthetics products, retailers can capitalize on selected situations in which to promote product aesthetics.     

人口老龄化背景下回归家庭养老的路径选择

随着我国人口老龄化进程的加快,养老模式与路径选择问题日益成为社会关注的主要问题。当前,家庭养老功能弱化,社会养老保障体系尚未完全形成,养老问题面临着新的困境。虽然养老模式开始逐渐趋于社会化和多元化,但家庭养老在我国有着很深的根基和不可替代的优势,在应对老龄化的过程中仍有着重要的支撑作用。家庭养老不仅有利于家庭关系的稳定和人力资本的投资,还能节约公共财政和社会资源。家庭养老的困难和危机不仅源于自身,还产生于社会和国家,政府应加大对家庭养老的支持力度,完善家庭养老保障的相关制度,强化家庭养老的社会关系网络,加大"孝"文化的宣传和教育。     

Using work design to motivate customer-oriented behaviors

Front-line employee (FLE) attitudes and behaviors while interacting with consumers largely determine the success or failure of service organizations. To better understand how this happens, this research moves beyond the oversimplified argument that managers either must hire or specifically train for workers to be customer oriented and to perform customer-oriented behaviors (COBs). A third path is proposed and empirically explored that suggests managers use work design to influence FLEs at work motivation to perform COBs. Specific work design levers managers can employ – manager support and serial/investiture socialization – are shown to impact FLE organizational commitment and role clarity with customers. Through these individual internal processes service organizations motivate front-line workers to perform desired COBs.

Consumer response to service brand physical elements: Using a semantic priming task to explore implicit understanding of service brand meaning

Consumers' responses to design features involve both conscious and non-conscious information processing. The current research therefore argues that a combination of explicit and implicit measures should be used to assess consumer understanding of service brand meaning conveyed by a service brand's physical elements. However, most methods traditionally used to evaluate design meaning are explicit methods, based on conscious cognitive processes. The current research addresses this gap by documenting how understanding of service brand meaning conveyed by a service brand's physical elements can be tapped by an implicit measure. More specifically, it aims to investigate the extent to which a greater ability to decode meaning conveyed by design features results in differences in implicit understanding of service brand meaning. This research uses a Semantic Priming Task to assess associative strength between brand meaning and a service brand's physical elements. Results (N = 157) show that command of the design language, captured by design acumen and involvement in the product category, results in greater ability to implicitly understand brand meaning conveyed by a service brand's physical elements, and moderates the implicit-explicit relationship. Results suggest that combining implicit and explicit measures may help practitioners in charge of creating brand's physical elements, especially when associations between design types and brand impressions are not constant across product categories.     

Using product design strategically to create deeper consumer connections

Historically, product design has most often been considered a process for creating functional differentiation through added features, superior performance, and so forth. However, with the advent of more design-oriented companies, such as Apple, Dyson, and others, design is increasingly being seen as an important strategic tool in creating preference and deeper emotional value for the consumer. In this research, we show how different design elements may be used strategically to create two very different outcome chains from a consumer's perspective. This work shows that certain design elements are more likely to create functional product differentiation and transactional consumer outcomes, while other design strategies tap a more emotional form of value creation. As we show, an emotional focus in value creation is more likely to create desired and powerful outcomes such as loyalty, joy of use, and even passion. Given current business trends towards relationship-based customer management, this emphasis on emotional value creation through product design is particularly relevant. In order to make these ideas actionable, we offer specific product design strategies that managers can use to enhance the transactional and relational value of their customer relationships.     

Consumer participation in the design and realization stages of production: How self-production shapes consumer evaluations and relationships to products

Psychological responses of consumers to specific stages of self-production activities are investigated in four studies. Findings reveal that consumer participation in the realization stage (physical production) enhances affective commitment to the product. However, physical production without opportunity to express choice or creativity during the production process does not change the symbolic meaning of the product (how self-expressive it is) and, therefore, does not result in identification with the product. Participation during the design stage (input-specification) enhances identification, leading to affective commitment, which in turn enhances evaluation of the self-made product. Finally, engaging consumers in both the realization and design stages of the production process does not create value for consumers over and above the main effects created by a high level of participation in either stage.     

一种二阶锥规划通带线性相位FIR滤波器的设计

在有限冲激响应（Finite Impulse Response,FIR）滤波器设计中,如果系统只要求通带或某个频域区间具有线性相位而其他频域区间相位非线性,则系数对称的FIR滤波器设计方法不再适用。为此,提出了一种基于二阶锥规划（Second-Order Cone Programming,SOCP）的通带线性相位FIR滤波器设计方法。该方法使用二阶锥规划实现滤波器设计,其中优化目标为通带最小群延迟,约束条件为全频域振幅误差。实验结果显示,所提方法设计的FIR滤波器有着很好的幅频特性和通带线性相位,通带群延迟误差很小。该方法实现简单,计算复杂度低,可以广泛应用于数字信号处理领域。     

How companies use typeface design to engage consumers in charitable activities

This research examines how the typeface design in a charitable appeal affects consumers' evaluations of the ad and, in turn, their willingness to engage in the advertised charitable activities. We propose that the typeface's simulation of a handwritten note creates a sense of connectedness to the information sender (e.g., organization, brand), which subsequently increases consumers' willingness to engage in the advertised charitable activities. Six experiments, including laboratory and field studies, provide support for the typeface effect and further support the underlying process by (1) directly examining connectedness, and (2) manipulating brand attachment, showing that a handwritten typeface creates a more positive effect when the viewer is not strongly connected to the brand (vs. having a strong brand attachment). Our findings provide useful guidelines for brand managers, social marketers and charity fundraisers regarding how and when to use a handwritten typeface design.     

Using design science to improve web search innovation in real estate

We analyze 14 leading real estate websites, seven residential and seven commercial. They exhibit limited demographic and geographic information systems (GIS) data display capability. They exhibit economic data display capability except one, and lack demographic, economic, and GIS data search capability. Real estate web searching is inefficient, time consuming, and inflexible. To overcome these limitations, we use design-science to create three search modes (Sc2, Sc3, and Sc4). Sc2 uses demographic data, Sc3 economic data, and Sc4 GIS data.

The friluftsliv response: Connection,drive, and contentment reactions to biophilic design in consumer environments

It is well documented that context and physical surroundings impact consumers. However, little is known about how to direct the overall design of an environment to enhance consumer experience. Evidence suggests that design principles that tap into the benefits of response to nature may serve to improve the well-being of people in the environment. While research on the implications of such design for consumer responses is growing, a conceptual framework that delineates these responses and their effects on experience has not been established. The current research develops, proposes, and tests a conceptual framework for consumer responses to environments that incorporate materials, textures, shapes, colors, and patterns that quote nature. It shows that when present in a consumer context, these biophilic design elements elicit what we label the friluftsliv response: a response characterized by a positive connection to place that elicits both drive and contentment-based affective reactions. The results indicate that consumer environments rich in biophilic design elements can positively influence important marketing variables, such as situational consumer anxiety and retailer choice.
