Costs of partner search and selection in strategic alliances

This study examines the costs associated with alliance partner search and selection as well as their antecedents. Based on transaction cost economics and the network perspective on inter-organizational relationships, the findings drawing on survey-based data from a sample of 83 firms in the German telecommunications industry reveal that partner search and selection costs are closely connected but differentially affected by task- and company-related factors. When firms must make alliance-specific investments, search and selection costs increase. A firm’s number of current alliances decreases search and selection costs, whereas neither alliance scope nor firm performance significantly affect them. Additional analyses show that alliance-specific investments especially increase search costs but do not affect selection costs, whereas a firm’s performance decreases search costs but does not reduce selection costs.     

A new variable importance measure for random forests with missing data

Random forests are widely used in many research fields for prediction and interpretation purposes. Their popularity is rooted in several appealing characteristics, such as their ability to deal with high dimensional data, complex interactions and correlations between variables. Another important feature is that random forests provide variable importance measures that can be used to identify the most important predictor variables. Though there are alternatives like complete case analysis and imputation, existing methods for the computation of such measures cannot be applied straightforward when the data contains missing values. This paper presents a solution to this pitfall by introducing a new variable importance measure that is applicable to any kind of data—whether it does or does not contain missing values. An extensive simulation study shows that the new measure meets sensible requirements and shows good variable ranking properties. An application to two real data sets also indicates that the new approach may provide a more sensible variable ranking than the widespread complete case analysis. It takes the occurrence of missing values into account which makes results also differ from those obtained under multiple imputation.     

Therapists’ Personal Experiences in Their Work with Clients Who Have Sexually Offended against Children: A Phenomenological Study

ABSTRACT

The need for professionals working with people who have committed sexual offenses is increasingly recognized. Still, relatively little is known about the personal impact of work with this population. Most research in the field has aimed to determine treatment providers’ level of work-related stress and hence focused on negative aspects of experience. Moreover, most of these studies have been conducted with questionnaires and yielded mixed results. In order to learn more about individual, contextual and dynamic aspects of therapists’ personal experiences with these clients, we suggest to drawing from in-depth interview studies and Interpretive Phenomenological Analysis (IPA). In the present study, four therapists working in Norway were interviewed. Surprisingly, the participants described their work as rewarding, despite the challenges they encountered. In fact, they considered their work to be rewarding precisely because of its challenging nature. The implications of these results for clinical practice and future research will be discussed.     

Business Exit and Strategic Change: Sticking to the Knitting or Striking a New Path?

The purpose of this study is to examine the potential of business exit for initiating strategic change in divesting parent firms. In contrast to prior literature that mainly investigates the impact of different antecedents on the likelihood of business exit in general, this study additionally tests the influence of these antecedents on the choice between two exit types with a cross‐industry sample of divesting firms listed in the German CDAX over the time period 1999–2004. A divestiture involving strategic change is a strategic business exit; otherwise it is denoted as status quo preserving. The findings reveal that a relatively highly dissipated focus does not automatically enhance the likelihood of business exit in general and status‐quo‐preserving business exit in particular. CEO turnover and pressures exerted by institutional investors predict neither strategic nor status‐quo‐preserving business exit. Low firm performance does not nurture the likelihood of business exit per se but especially promotes status‐quo‐preserving business exit.     

A Robust Test for Weak Instruments

This article deals with the estimation of continuous-time stochastic volatility models of option pricing. We argue that option prices are much more informative about the parameters than are asset prices. This is confirmed in a Monte Carlo experiment that compares two very simple strategies based on the different information sets. Both approaches are based on indirect inference and avoid any discretization bias by simulating the continuous-time model. We assume an Ornstein-Uhlenbeck process for the log of the volatility, a zero-volatility risk premium, and no leverage effect. We do not pursue asymptotic efficiency or specification issues; rather, we stick to a framework with no overidentifying restrictions and show that, given our option-pricing model, estimation based on option prices is much more precise in samples of typical size, without increasing the computational burden.     

Linkages between mothers’ job stressors and adolescents’ perceptions of the mother–child relationship in the context of weak versus strong support networks

This study tested the hypothesis that mothers’ exposure to psychosocial job stressors would be indirectly associated with less favorable ratings of the mother–adolescent relationship, as perceived by youth, by way of mothers feeling depleted of cognitive and emotional energies after work. We also examined whether mothers’ perceptions of being socially supported with regard to work and family responsibilities moderate associations between greater psychosocial job stressors and lesser quality in the mother–adolescent relationship. The sample consisted of 169 diverse mother–early adolescent dyads. Mothers and adolescents completed surveys independently. Hypotheses were tested through structural equation modeling and multi-group comparisons. Psychosocial job stressors were indirectly related to qualities of the mother–adolescent relationship via their association with mothers’ experiences of psychological energy depletion from work to family. The most consistent evidence for these associations was found among women who felt less social support in regard to their work–family responsibilities.     

Interface methods: renegotiating relations between digital social research,STS and sociology

This paper introduces a distinctive approach to methods development in digital social research called ‘interface methods’. We begin by discussing various methodological confluences between digital media, social studies of science and technology (STS) and sociology. Some authors have posited significant overlap between, on the one hand, sociological and STS concepts, and on the other hand, the ontologies of digital media. Others have emphasized the significant differences between prominent methods built into digital media and those of STS and sociology. This paper advocates a third approach, one that (a) highlights the dynamism and relative under‐determinacy of digital methods, and (b) affirms that multiple methodological traditions intersect in digital devices and research. We argue that these two circumstances enable a distinctive approach to methodology in digital social research – thinking methods as ‘interface methods’ – and the paper contextualizes this approach in two different ways. First, we show how the proliferation of online data tools or ‘digital analytics’ opens up distinctive opportunities for critical and creative engagement with methods development at the intersection of sociology, STS and digital research. Second, we discuss a digital research project in which we investigated a specific ‘interface method’, namely co‐occurrence analysis. In this digital pilot study we implemented this method in a critical and creative way to analyse and visualize ‘issue dynamics’ in the area of climate change on Twitter. We evaluate this project in the light of our principal objective, which was to test the possibilities for the modification of methods through experimental implementation and interfacing of various methodological traditions. To conclude, we discuss a major obstacle to the development of ‘interface methods’: digital media are marked by particular quantitative dynamics that seem adverse to some of the methodological commitments of sociology and STS. To address this, we argue in favour of a methodological approach in digital social research that affirms its maladjustment to the research methods that are prevalent in the medium.     

Investigating the use of information technology in managing innovation: A case study from a university technology transfer office

This study investigates the use of information technology to manage innovation. It is based on a case study on the adoption of an innovation application, which provides an interface between R&D, marketing and administration functions of innovation development. Drawing on qualitative evidence including a focus group and 16 in-depth interviews, this study contributes by integrating technology acceptance constructs to innovation process performance and marketing literature, as well as by investigating technology acceptance in an innovation context. Implications are discussed for organizations engaged with R&D or innovation process management and suggestions for research directions are offered.     

What drives contract design in alliances? Taking stock and how to proceed

We collect and assess prior empirical evidence on contract design in alliances that has been published since Parkhe’s (1993) seminal study on inter-firm contracts. We elaborate on the effects of transaction-related factors, experience gained from prior relationships, and deliberate learning efforts on contracts. Our paper offers three contributions. First, we systematically review the existing literature on alliance contracts and summarize our findings. Second, while prior research has traditionally focused on contractual complexity, we place the content of contracts center stage and identify three contractual functions. While existing studies on contractual functions predominantly refer to safeguarding as a response to appropriation concerns, we also consider coordination and contingency adaptability as outcomes of adaptation concerns. Third, we disentangle the differential influences of previous experiences on distinct contractual functions and show that experience gained from prior relationships has different effects on safeguarding and contingency adaptability than on coordination. Overall, we add to the systematization of the current debate on alliance contract design and trace promising avenues for future research on the impact of transaction- and experience-related factors on the complexity and content of alliance contracts.     

The evolution of university–industry linkages—A framework

This qualitative study extends literature on research commercialization by examining the dynamic nature of university–industry linkages (UIL). Thirty in-depth interviews conducted in Australia and Germany/the Netherlands provide evidence of the different phases through which UILs evolve and respective measures of success. Communication, understanding, trust, and people are universal drivers, yet managers must consider the variations in the nature of these factors to ensure successful UILs. This study equips managers involved in technology transfer, innovation, and commercialization with critical insights into developing effective relationships. The proposed conceptual framework also uncovers notable theoretical and managerial implications and offers some key research directions.
