Top Management Team Members’ Decision Influence and Cooperative Behaviour: An Empirical Study in the Information Technology Industry

Organizational leadership is generally distributed between the chief executive officer (CEO) and the top management team (TMT) members. Building on this observation, we present an empirical investigation of the cues for CEOs to delegate decision‐making influence to particular TMT members. In the literature, explanations both based on expertise and driven by similarity are described. In this study, we reconcile both explanations by examining the moderating role of the TMT's level of ‘cooperative behaviour’ (collaboration and information exchange). We analyse when and in what circumstances TMT members’ expertise and similarity to the CEO regarding his/her functional background and/or locus‐of‐control predict their decision‐making influence. We postulate that TMT cooperative behaviour will advance the effect of expertise on TMT members’ decision influence but impede the effect of similarity to the CEO. Our hypotheses are tested on a data set of 135 TMT members from 32 Dutch and Belgian information technology firms. Overall, we find that our proposed research model is confirmed for technology‐oriented decisions. Furthermore, we draw exploratory conclusions about the effect of TMT cooperative behaviour on the systematic distribution of decision influence in TMTs.     

Humanitarian work psychology: The contributions of organizational psychology to poverty reduction

Achieving the MDG goal of reducing world poverty by 50% by 2015 requires the cooperative effort of many disciplines. To date the discipline of organizational psychology has not played as significant a role as it might in this endeavor. With the recent establishment of the Global Task Force for Humanitarian Work Psychology, this discipline signaled its commitment to the global effort. Organizational psychology offers to bring its expertise to poverty reduction: its ability to assess needs and capacity, develop partnerships with stakeholders, bring about and manage change, and systematically review, evaluate, monitor and revise high level mandates, policy development, program implementation and consultation on personnel issues. Its successes as practitioners-scientists in private enterprise will enhance its credibility for success in the public sphere. The article reviews the research and practice of some of the organizational psychologists presently engaged in poverty reduction and how humanitarian work psychology might enhance the efforts of anti-poverty organizations.     

Multi-profile intergenerational social choice

In an infinite-horizon setting, Ferejohn and Page showed that any social welfare function satisfying Arrow’s axioms and stationarity must be a dictatorship of the first generation. Packel strengthened this result by proving that no collective choice rule generating complete social preferences can satisfy unlimited domain, weak Pareto and stationarity. We prove that this impossibility survives under a domain restriction and without completeness. We propose an alternative stationarity axiom and show that a social welfare function on a specific domain satisfies this modified version and some standard social choice axioms if and only if it is a chronological dictatorship.     

Multicultural supervision: lessons learned about an ongoing struggle

This article examines the experiences of seven diverse therapists in a supervision course as they wrestled with the real-world application of multicultural supervision. Existing literature on multicultural supervision does not address the difficulties that arise in addressing multicultural issues in the context of the supervision relationship. The experiences of six supervisory candidates and one mentoring supervisor in addressing multicultural issues in supervision are explored. Guidelines for conversations regarding multicultural issues are provided.     

Social skills of adopted Chinese girls at home and in school: Parent and teacher ratings

This study examines adopted Chinese girls' social skills at home and in school as well as the effect of pre-adoption adversity on these skills. Parent ratings of 869 girls and teacher ratings of 611 of the 869 girls were obtained using the Social Skills Rating System for parent (SSRS-P) and teacher (SSRS-T) respectively. The girls were adopted on average at 15.6 months (SD = 13.9) and were in three age groups, including preschool, elementary school, and secondary school. Data on five indicators of pre-adoption adversity (i.e., signs/symptoms, delays at adoption, initial refusal/avoidance of adoptive mothers, crying/clinging behaviors, and age at adoption) were obtained from the same adoptive parents 2 years prior. Findings suggest that both parents and teachers rated the girls as either similar to or better than US norms on the SSRS. Parent–teacher agreement on SSRS subscales was significant but modest (rs = 0.12–0.25). Two indicators of pre-adoption adversity (i.e., delays at adoption and initial refusal/avoidance of adoptive mothers) predicted poorer social skills at home; two other indicators of pre-adoption adversity (i.e., signs/symptoms and age at adoption) predicted poorer social skills in school.     

Every Choice Function Is Backwards‐Induction Rationalizable

A choice function is backwards‐induction rationalizable if there exists a finite perfect‐information extensive‐form game such that for each subset of alternatives, the backwards‐induction outcome of the restriction of the game to that subset of alternatives coincides with the choice from that subset. We prove that every choice function is backwards‐induction rationalizable.     

How Inventory Cost Influences Introduction Timing of Product Line Extensions

In the industry with radical technology push or rapidly changing customer preference, it is firms' common wisdom to introduce high‐end product first, and follow by low‐end product‐line extensions. A key decision in this “down‐market stretch” strategy is the introduction time. High inventory cost is pervasive in such industries, but its impact has long been ignored during the presale planning stage. This study takes a first step toward filling this gap. We propose an integrated inventory (supply) and diffusion (demand) framework and analyze how inventory cost influences the introduction timing of product‐line extensions, considering substitution effect among successive generations. We show that under low inventory cost or frequent replenishment ordering policy, the optimal introduction time indeed follows the well‐known “now or never” rule. However, sequential introduction becomes optimal as the inventory holding gets more substantial or the product life cycle gets shorter. The optimal introduction timing can increase or decrease with the inventory cost depending on the marketplace setting, requiring a careful analysis.
