Becoming familiar with eternal anonymity: how sperm banks use relationship marketing strategy

The article focuses on donor profiles as a major marketing tool of the fertility industry and proposes some theoretical insights into sperm banking and sperm consumption, using a content analysis of 135 extended sperm donor profiles and a visual analysis of 36 baby photos in nine sperm banks. Theorizing sperm consumption is inspired by Grönroos' conceptualization of relationship marketing (RM). Contrary to conventional logic, I show how RM itself has become a product on its own, rather than a business strategy: while the sperm consumer is invited through anonymously written narratives to become an active prosumer by encoding and decoding parts of the donor's identity, the imaginary relationship with the donor constitutes the core product. Since donor profiles are purchased as a complementary service product, sperm banks activate identity construction among the donors by asking them to provide lengthy essays; donors produce polyphonic narratives and therefore participate in a Bakhtinian mask parade.

Sustainability ranking and improvement of countries

Human society is on a collision course with nature, thus its sustainability is seriously questioned nowadays. To understand this problem better it is essential to define and measure sustainability. In this paper a model that uses fuzzy logic, called SAFE, is used to measure sustainability. The sustainability of a country is based on a multitude of basic indicators. In all 75 indicators for 128 countries are used. This work extends SAFE as follows: (a) The model is amended by an imputation procedure to fill in missing data, (b) the rule bases of SAFE are compiled algebraically, and (c) sustainability thresholds are defined so as to reflect expert opinion and international agreements and norms. Countries are ranked according to their sustainability index. Switzerland and Sweden take the first two places and Mauritania and Sudan the two last ones. A sensitivity analysis pinpoints those basic indicators that affect sustainability the most. Decision makers may focus on these indicators to improve sustainability.     

认知无线电系统中利用模糊逻辑的频谱分配

为了较全面地分析频谱分配问题,突出系统的效益和公平性能,提出了一种利用模糊 逻辑的认知无线电频谱分配方案。首先给出模糊逻辑系统（FLS）的概念,然后利用FLS综合 分析感知空闲频谱和次用户的特性,最后结合系统吞吐量最大、公平性和随机分配3种准则 将空闲频谱分配给次用户使用。仿真结果证实了方案的可行性。

Value co-creation via information and communications technology

The aims of the present work centre on determining whether co-created value constitutes a competitive advantage for firms, and whether it is capable of influencing consumer behaviour. Applying the service-dominant logic perspective, the work examines the firm's capabilities in the context of its business-to-customer (B2C) interactions, focusing on information and communications technology (ICT) as a particular driver of value co-creation. Taking this B2C perspective, ICT is measured, from the firm's point of view, and customer perceptions are analysed, using the variables ‘value co-creation’, ‘perceived value’ and ‘loyalty’. The sample consists of 100 service firms and 572 of their customers. The findings indicate that ICT capabilities have a direct effect on value co-creation, as does value co-creation on perceived value and loyalty.     

Zooming in VS zooming out on value co-creation: Consequences for BtoB research

The concept of value co-creation is now taken for granted in the marketing community. It is the result of what we consider as a premature closure of this concept. The aim of this article is to prevent this premature closure by confronting what this discipline has produced thus far in order to highlight the breadth of situations that this concept presumes to encompass. To achieve this, we analyze a selection of articles published in special issues of marketing journals that were dedicated to value co-creation and/or service dominant logic. This sample enables us to point to the risks of being locked into a zoom-out approach to economic exchange: an arbitrary reduction of the vast heterogeneity of exchange phenomena and an inability to account for the complexity of these phenomena. Because value co-creation is a conception that is in conflict with the zoom-in approach to exchange phenomena, our intent is to conduct a healthy rebalancing of perspectives on economic exchange and thereby keep the controversy alive.
