The impact of different fit dimensions on spillover effects in brand alliances

Brand alliances represent a popular business strategy in many industries, because firms hope to evoke positive consumer evaluations of both the alliance’s product and the partner brands. However, extant research offers mixed findings regarding the effects of a brand alliance on its partner brands (i.e., spillover effects). In response, this study separates spillover effects into the effects of the alliance product on the partner brands (brand alliance effects) and the effects between partner brands (brand contrast effects), while also noting the potential moderating impact of perceived attitude- and product-based fit between partner brands on resulting spillover effects. Two experimental studies consistently reveal the existence of brand contrast effects; furthermore, the partner brand’s attitude-based fit reduces undesired brand contrast effects and positively moderates spillover effects in brand alliances, whereas product-based fit does not. Therefore, a third study identifies relevant drivers of partner brand’s attitude-based fit for different brand alliances (i.e., co-branding, ingredient branding, and joint advertising). The findings have notable implications for the design and management of brand alliances.     

System Dynamics as a Structural Theory in Operations Management

The purpose of the paper is to demonstrate the usefulness of (1) system dynamics as a structural theory for operations management and (2) system dynamics models as content theories in operations management. The key findings are that, although feedback loops, accumulation processes, and delays exist and are widespread in operations management, often these phenomena are ignored completely or not considered appropriately. Hence, it is reasoned why system dynamics is well suited as an approach for many operations management studies, and it is shown how system dynamics theory can be used to explain, analyze, and understand such phenomena in operations management. The discussion is based on a literature review and on conceptual considerations, with examples of operations management studies based on system dynamics. Implications of using this theory include the necessary re‐framing of some operations management issues and the extension of empirical studies by dynamic modeling and simulation. The value of the paper lies in the conceptualization of the link between system dynamics and operations management, which is discussed on the level of theory.     

‘We the People’ versus ‘We the Heads of States’: the debate on the democratic deficit of the European Union

The Eurozone crisis has rekindled the debate on the democratic deficit of the European Union (EU). In this paper, the debate is reconsidered by contrasting the modus vivendi of ‘We the People’ in the USA with the modus vivendi of ‘We the Heads of States’ in the EU. It is demonstrated that many of the solutions to the alleged democratic deficit focus on how more voice can be given to ‘We the People’ on the input side, but that this goes against the functional logic of the EU system, thereby undermining its ability to govern. Instead, we argue that more attention should be given to how to increase output legitimacy, and a number of proposals are put forward. Such a reshuffling of the analytical focus is the best way forward to escape the current impasse in the debate on how to ‘fix’ democracy in the EU.     

Exploring the Conceptual Foundation of Continuity Management in the Context of Societal Safety

Public and private actors with critical roles for ensuring societal safety need to work proactively to reduce risks and vulnerabilities. Traditionally, risk management activities have often been performed in order to ensure continuous functioning of key societal services. Recently, however, business continuity management (BCM), and its analytical subcomponent business impact assessment (BIA), has been introduced and used more extensively by both the private and public sector in order to increase the robustness and resilience of critical infrastructures and societal functions and services. BCM was originally developed in the business sector but has received a broader use during the last decade. Yet, BCM/BIA has gained limited attention in the scientific literature—especially when it comes to clarifying and developing its conceptual basis. First, this article examines and discusses the conceptual foundation of BCM concepts, including practical challenges of applying the concepts. Based on recent conceptual developments from the field of risk management, a developed conceptualization is suggested. Second, the article discusses challenges that arise when applying BCM in the societal safety area and provides some recommendations aiming to improve the clarity and quality of applications. Third, the article provides suggestions of how to integrate the overlapping approaches of BIA and risk assessment in order to improve efficiency and effectiveness of proactive, analytic processes. We hope that the article can stimulate a critical discussion about the key concepts of BCM, their wider use in societal safety, and their connection to other concepts and activities such as risk assessment.

Contentious connective action: a new kind of life-political association for problematizing how expert systems operate

Neoliberalism and populism both challenge the idea that democratic politics is of and by ‘the people.’ Neoliberalism suggests technocracy as the way ahead for nudging laypeople to do the right things. Populism appeals to the morality of an exceptional leader required for tumbling ‘the system’ and make the home of ‘We the People’ whole again. Both positions consider laypeople like clay to be formed in their own image. The logic of contentious connective action is a direct response to this political degradation of the layactor. Without laypeople being able chronically to problematize how things are done by expert systems, there can be no real democracy. Hence, it is about time we bring the lifeworld with its capable and knowledgeable laypeople back into the fold. Technological development has made it possible for the lifeworld to attain global and not just local significance. Its spontaneous activities in local time-space can now connect globally, enabling worldwide demonstrations in the name of ‘we the 99%.’     

Improving evidence-based social work practice with youths exhibiting conduct problems through structured assessment

A key task in evidence-based case management of youth is the assessment of research-based risk and protective factors. In the present study we compare assessments of social workers using a structured assessment instrument with assessments of social workers not using such an instrument. Assessments of the exact same case—a vignette about a 14-year-old boy—conducted by 30 social workers using a structured assessment instrument and 30 social workers not using such an instrument were compared. The 60 assessments were also rated by independent researchers and senior social services managers, blind to whether an instrument had been used in the assessments or not. As hypothesized, using a structured assessment instrument resulted in the identification of a greater number of research-based risk and protective factors, and the assessments were rated as better in terms of general adequacy, quality, accuracy and potential treatment effectiveness, than when an instrument was not used. The present study demonstrates that social workers’ assessments of youth become more evidence-based, adequate and potentially more treatment effective when a structured assessment instrument is used as compared to when it is not.     

Value of Statistical Life and Cause of Accident: A Choice Experiment

The purpose of this study is to compare the value of statistical life (VSL) estimates for traffic, drowning, and fire accidents. Using a choice experiment in a mail survey of 5,000 Swedish respondents we estimated the willingness to pay for risk reductions in the three accidents. In the experiment respondents were asked a series of questions, whether they would choose risk reducing investments where type of accident, cost of the investment, the risk reduction acquired, and the baseline risk varied between questions. The VSLs for fire and drowning accidents were found to be about 1/3 lower than that for traffic accidents. Although respondents worry more about traffic accidents, this alone cannot explain the difference in VSL estimates. The difference between fire and drowning accidents was not found to be statistically significant.     

Using continuation-ratio logits to analyze the variation of the age composition of fish catches

Major sources of information for the estimation of the size of the fish stocks and the rate of their exploitation are samples from which the age composition of catches may be determined. However, the age composition in the catches often varies as a result of several factors. Stratification of the sampling is desirable, because it leads to better estimates of the age composition, and the corresponding variances and covariances. The analysis is impeded by the fact that the response is ordered categorical. This paper introduces an easily applicable method to analyze such data. The method combines continuation-ratio logits and the theory for generalized linear mixed models. Continuation-ratio logits are designed for ordered multinomial response and have the feature that the associated log-likelihood splits into separate terms for each category levels. Thus, generalized linear mixed models can be applied separately to each level of the logits. The method is illustrated by the analysis of age-composition data collected from the Danish sandeel fishery in the North Sea in 1993. The significance of possible sources of variation is evaluated, and formulae for estimating the proportions of each age group and their variance-covariance matrix are derived.
