Young Adolescents and Advertising on Social Network Games: A Structural Equation Model of Perceived Parental Media Mediation,Advertising Literacy,and Behavioral Intention

This study tested a model in which perceived parental media mediation in social network games (SNGs) was related to adolescents' conceptual and attitudinal advertising literacies, both of which were in turn related to purchase request intention. The 780 participants, aged between 10 and 14 years, watched a video clip of SNG Habbo that included a commercial message and then completed a questionnaire. Perceived autonomy-supportive restrictive media mediation was found to be positively associated with understanding selling intention. Perceived autonomy-supportive active media mediation was positively related to understanding persuasive intention. Understanding persuasive intention was positively related to purchase request intention.     

The effect of the elapsed time between the initial refusal and conversion contact on conversion success: evidence from the 2nd round of the European social survey

The hold period between the initial refusal and the follow-up conversion attempt may be used as a strategic tool to improve conversion rates. We argue that longer hold periods result in better conversion rates, particularly among hard-to-convert refusals. In this article we will first investigate to what extend and in which manner survey authorities exert this elapsed time as an active survey instrument. Contact sheet data show that different national survey coordinators deploy different strategies with regard to this hold period. In the Netherlands, intentional survey tactics can be disentangled, whereas Swiss contact data show that the length of the hold period is a mere result other fieldwork conditions. Actual conversion success seems to be consistently dependent upon the hold period between the initial refusal and the follow-up contact.     

Qualitative One-to-Many Multi-Issue Negotiation: Approximating the QVA

When there is one buyer interested in obtaining a service from one of a set of sellers, multi-attribute or multi-issue auctions can ensure an allocation that is efficient. Even when there is no transferable utility (e.g., money), a recent qualitative version of the Vickrey auction may be used, the QVA, to obtain a Pareto-efficient outcome where the best seller wins. However, auctions generally require that the preferences of at least one party participating in the auction are publicly known, while often making this information public is costly, undesirable, or even impossible. It would therefore be useful to have a method that does not impose such a requirement, but is still able to approximate the outcome of such an auction. The main question addressed here is whether the Pareto-efficient best-seller outcome in multi-issue settings without transferable utility (such as determined by the QVA) can be reasonably approximated by multi-bilateral closed negotiation between a buyer and multiple sellers. In these closed negotiations parties do not reveal their preferences explicitly, but make alternating offers. The main idea is to have multiple rounds of such negotiations. We study three different variants of such a protocol: one that restricts the set of allowed offers for both the buyer and the seller, one where the winning offer is announced after every round, and one where the sellers are only told whether they have won or not after every round. It is shown experimentally that this protocol enables agents that can learn preferences to obtain agreements that approximate the Pareto-efficient best-seller outcome as defined by the auction mechanism. We also show that the strategy that exploits such a learning capability in negotiation is robust against and dominates a Zero Intelligence strategy. It thus follows that the requirement to publicly announce preferences can be removed when negotiating parties are equipped with the proper learning capabilities and negotiate using the proposed multi-round multi-bilateral negotiation protocol.     

The impact of regulatory focus on adolescents’ evaluation of targeted advertising on social networking sites

This article examines whether individual differences in chronic regulatory focus (prevention vs. promotion focus) among adolescents influences the way they evaluate targeted advertising on social networking sites. Study 1 (survey) reveals that adolescents with a promotion focus (who are oriented toward achieving positive outcomes) have a more positive attitude and a higher purchase intention toward targeted advertising, as compared to prevention-focused adolescents (who are dispositioned toward avoiding negative outcomes). Study 2 (experiment) investigates how adolescents’ chronic regulatory focus can alter their attitude and purchase intention on a mock social networking site that includes a targeted advertisement. Results show that a low personalized targeted ad is better evaluated (in terms of a more positive attitude and higher purchase intention) among prevention-focused adolescents, whereas a high personalized targeted ad results in better advertising outcomes among promotion-focused adolescents. Contributions to theory and implications for advertising practice are discussed.     

Price rather than nutrition information the main influencer of consumer food purchasing behaviour in South Africa: A qualitative study

In South Africa there has been a paucity of data on food and nutrition labelling since the publication of the new food‐labelling legislation. This study aimed to explore whether the nutrition information on food products influences consumer purchasing behaviour; reasons for reading or ignoring nutrition information on labels, and to investigate expectations regarding food / nutrition labelling. Nine focus‐group discussions were held with adult consumers (N=67) in Cape Town, South Africa. Food price was sometimes the only consideration when selecting food products, irrespective of quality and nutritional value. When buying products for the first time, consumers were more inclined to read the nutrition information compared to habitual purchases or buying known brands. The list of ingredients, nutrient content claims and specific health endorsement logos were considered important. Reasons for reading nutrition information were mainly to assess the nutritional value or health properties, to avoid certain ingredients/allergens and to determine quality. Consumers struggled to understand the information on labels, specifically the nutrition information table. A lack of time or interest, price concerns and trust in labelling information also emerged as reasons why consumers ignore the nutrition information. There is a need for simpler food labelling, more graphics, and less complex terminology, information overload and quantitative information. It is recommended that a standardised front‐of‐package labelling scheme and a single health endorsement logo for South Africa be considered. More should be done to educate consumers on utilising the information on food labels correctly, in order for them to make healthier food choices.     

Export variety and the economic performance of countries

We explore the relationship between export variety and economic development, using data on OECD countries between 1964 and 2003. We show that structural change in the world economy has a particular arrow of time leading to a growing variety of exports. Distinguishing between related variety (within sectors) and unrelated variety (variety between sectors), we also show that related variety stimulates growth instantaneously, while unrelated variety only promotes growth with a considerable time lag. This finding is in line with the evolutionary notions that economic development and international trade patterns are path dependent.

R&D portfolios in environmentally friendly automotive propulsion: Variety, competition and policy implications

In this article, we analyze R&D portfolios in environmentally friendly automotive propulsion including alternative fuel options. We argue that at the current stage of development, substitution of conventional car technology by a new automotive propulsion technology may lead to premature lock-in of suboptimal technology. To avoid such lock-in, one should value the variety of current R&D activity that enables organizations to learn from multiple options and to create spillovers between options. We further argue that the existence of technological variety is not a sufficient condition to avoid lock-in. Organizational variety is also required to sustain competition and avoid the dominance of few firms that possibly enforce a suboptimal technology within the sector. To assess whether recent developments in R&D have led to both technological variety and organizational competition, we analyze United States Patent and Trademark Office (USPTO) patents in low-emission vehicles (LEVs) during the period 1980–2001 using entropy statistics. Results show that both technological variety and organizational competition have increased steadily since the early nineties, suggesting that premature lock-in is unlikely to occur. From an environmental policy evaluation perspective, we consider the findings as a positive evaluation of the 1990 Californian Low Emission Vehicle program.     

Antecedents and consequences of performance management enactment by front-line managers. Evidence from Belgium

Although researchers have extensively stressed the critical role of line managers in the effective implementation of HR practices, little is known about what exactly causes managers to enact these practices. In this paper, we draw from signaling theory, theory of planned behavior and social exchange theory to investigate both the antecedents and the outcomes of front-line management’s enactment of performance management (PM) activities. Results from two Belgian samples of 731 front-line managers and 425 employees show that line management’s beliefs regarding the usefulness of PM activities mediate the relationship between HR support and line management’s implicit person theory, on the one hand, and PM enactment, on the other. This relationship is moderated by the manager’ span of control. Furthermore, line management enactment shows to be positively related to employee engagement and job satisfaction.
