Requirements Engineering for Product Service Systems

In recent years, manufacturing companies and service providers have moved towards offering customer-specific problem solutions. These integrated bundles usually consist of hardware, software, and service components and are called product service systems (PSS) or hybrid products. Since the success of the resulting solution depends on the understanding of all requirements, requirements engineering (RE) has become a key factor. The article analyzes the state of the art of RE for PSS based on an extensive literature review in the domains of product-, software-, and service engineering. For this, criteria are derived from the characteristics of PSS and from the task area of RE in the life cycle of PSS. Based on these criteria we analyze the most established RE approaches for their suitability for PSS. An important finding is that integrated/interdisciplinary approaches for RE are missing. Moreover, the maturity of RE approaches in the three domains varies significantly. All analyzed approaches heavily rely on concepts and solution characteristics of their own domain so that a transfer to other domains is hardly possible. This literature review lays the foundation for successful RE for PSS and especially for future research aiming at combining and integrating RE approaches and models of product-, software-, and service engineering. Such requirement models could connect concepts of single domains and enable an integrated and seamless RE for PSS.     

Funding sources and the strategic roles of decentralised R&D in multinationals

This paper analyses the sources of funding accessed by laboratories of foreign multinational enterprises (MNEs) operating in the UK. The five separate sources of funding are systematically related to four different roles that such labs are seen to play. The results confirm the view that decentralised R&D in MNEs now plays significant and carefully defined roles in the technological and competitive evolution of these enterprises. The strong position of central group funds is seen to reflect two trends in the status of decentralised labs. Firstly, to support their willingness to activate strong local scientific inputs for longer-term and speculative (risky) research programmes. Secondly, to inculcate an acceptance of individual labs to operate within interdependent networks of group operations (precompetitive research or product development).     

Are commercial bank lending propensities useful in understanding small firm finance?

We consider recent criticism by Berger et al. (J Bank Finance 31:11–33, 2007) of the use of commercial bank lending propensities (e.g., small business loans/total assets) as research tools. We use 2SLS cross sectional regressions with bank fixed effects to examine the relationship between small business lending and bank size. Our results indicate that the propensity to lend to small businesses declines as bank size increases, and the growth in small business lending does not keep pace with the growth in bank size. An increase in bank asset size from $1 billion to $100 billion reduces the ratio of small business loans to total loans and leases by 28 percentage points. Contrary to Berger and Black (2007) we find that most small business loans are made by small banks. For 1993 to 2006 as a whole, small banks (those under $1 billion) accounted for only 14.1% of total deposits and 9.7% of total banking assets, but they accounted for 28.4% of small business loans outstanding. This is consistent with the pattern shown by lending propensities. We conclude that these propensities remain very useful tools in research on small firm finance.     

Is Corporate Advertising Effective in a Crisis? The Effects of Crisis Type and Evaluative Tone of News Coverage

The present study examines how consumers respond to corporate advertising during a corporate crisis. In particular, it examines what impact two factors—crisis type and the evaluative tone of a news story—have on consumer responses to corporate advertising. Results of the experimental study suggest that the crisis type—an accident or a transgression crisis—is a critical factor affecting ad credibility and changes, between pre- and post-tests, in perceptions of and attitudes toward the corporation. In addition, the results reveal that while the effect of the evaluative tone of the news story is not statistically significant for each of the dependent variables, the marginally significant effect on the set of dependent variables calls for more careful attention to this issue in future research.     

How Much Do We Say? Using Informativeness of Negotiation Text Records for Early Prediction of Negotiation Outcomes

Business negotiations represent a form of communication where informativeness, i.e., the amount of provided information, depends on context and situation. In this study, we hypothesize that relations exist between language signals of informativeness and the success or failure of negotiations. We support our hypothesis through linguistic and statistical analysis which acquires language patterns from records of electronic text-based negotiations. Empirical results of machine learning experiments show that the acquired patterns are useful for early prediction of negotiation outcomes.     

A Cross-National Study of Personal Initiative as a Mediator between Self-Efficacy and Entrepreneurial Intentions

Although considerable research has highlighted that high levels of self-efficacy are associated with high levels of entrepreneurial intentions, little attention has been paid to the mediating effects of different variables on the relations between self-efficacy and entrepreneurial intentions. Integrating theoretical work on self-efficacy with personal initiative literature, I developed a model of entrepreneurial intentions that included both the independent effects of self-efficacy and control variables and the mediating effect of personal initiative on entrepreneurial intentions. I tested this model with a sample of 429 students from four universities in emerging and developed countries. Results indicate that personal initiative fully mediates the effect of self-efficacy on entrepreneurial intentions. I uncover that the level of self-efficacy is significantly higher among the students in an emerging economy. However, no significant difference was observed in the reported levels of personal initiative in two contexts.     

Looking good or feeling good? The dual role of the body in the taste transformation process

ABSTRACT

This paper investigates the process of taste transformation in body-centered consumption fields and the role of the body in this process. Although previous studies have investigated taste acquisition, the body is still commonly understood only as the enactor of the practices in this process. By analyzing the context of healthy living, this study identifies the body as a lived-in trigger of taste transformation and the main place where change unfolds. It demonstrates how, after taste transformation, the body becomes a lived-in enactor of practices that display mastery of the tenets of a taste regime but is still captured in normative systems that animate the desire for change. The findings reveal that the body is both situated in normative beauty systems and an embodied enactor of practices and that by unveiling its dual role, it allows individuals to navigate distinction-over and distinction-between.     

The interplay of culture and situational cues in consumers' brand evaluation

This research examines the effects of situational cues in consumers' brand evaluation; more importantly, this relationship is explored across the US and Korean cultures. The findings suggest that consumers prefer brands with personality traits that are congruent with the social situations. Furthermore, as predicted, this brand‐situation congruity, for which brand preference increases when the social situational cues are congruent vs. incongruent with the brand personality, is stronger among Korean vs. American subjects.     

Effect of Normative and Affective Aspects on Willingness to Pay for Domestic Food Products—A Multiple Price List Experiment

There is limited knowledge about which factors underlie consumers’ preferences for domestic food products. We used a non-hypothetical multiple-price list experiment to investigate the effect of affective (product-related emotions) and normative (consumer ethnocentrism and subjective norms) factors on consumer willingness to pay for domestic food products. A total of 166 Croatian consumers were given a choice between domestic and foreign food products with different price premiums for domestic food. The results indicate that consumers are willing to pay a premium for both low- and high-involvement domestic food products. Consumer willingness to pay for domestic products is influenced by ethnocentrism, product-related emotions, and sociodemographic variables, but not by social norms.
