Givers,takers and matchers – Reciprocity styles and their contribution to organizational behaviour

This article in the journal “Gruppe. Interaktion. Organisation (GIO)” bridges Adam Grant’s popular concept of givers, takers and matchers to state-of-the-art theories and research of prosocial organizational behavior such as Organizational Citizenship Behaviour (OCB). By proposing a three-dimensional framework of social orientation, the authors provide an approach allowing the reconciliation of inter-individual differences of social motives and situational factors, enabling cooperative behavior in the workplace. The practical implications of encouraging cooperative behaviour and collegial support are indicated for individual (personnel selection and development), team (team design and values) and organizational (organizational culture development) levels.     

Wirkungsweise von Combined-Currency Prices – Eine theoretische und empirisch experimentelle Analyse

Over the last few years, programs to enhance customer retention have strongly increased in popularity. Thus, a growing number of artificial currencies such as bonus points or miles have been created. In consequence, many products and services today can be paid by using a combination of real (e.g. Euro) and artificial currencies. These combined-currency prices offer marketers many possibilities to design prices. Yet, research dealing with the effects of such combined-currency prices is scarce. Therefore, our study addresses the effect of combined-currency prices on consumers' perception of prices purchase behaviour. Moreover, we analysed how such effects can be explained by taking into account important concepts of the field of price psychology. Our experimental results demonstrate that combined-currency prices strongly influence consumers' perception of price fairness. Particularly if planning to increase prices or when designing prices for bonus programs, marketers should therefore favour combined-currency prices instead of one-dimensional prices.     

The Role of Child Characteristics and Peer Experiences in the Development of Peer Cooperation

Cooperation with peers is challenging for young children, and there are large individual differences in the development of cooperation. The roles of child characteristics and peer experiences for peer interaction during free play have been studied extensively, but it is unclear which factors predict young children's successful cooperation at different points in development. In this study, 2‐, 3‐, and 4‐year‐old children were observed during a peer cooperation task. Both their interactive behavior and cooperation success were examined, and the association of these variables with child characteristics and peer experiences was explored. Results showed that successful peer cooperation increased with age. Moreover, early individual differences in peer cooperation were related to temperamental characteristics, and, among older children, the rate of cooperation was related to prior peer experience.     

The Architecture of Dynamic Capability Research Identifying the Building Blocks of a Configurational Approach

The dynamic capability view (DCV) of the firm has become one of the leading frameworks aimed at identifying drivers of long-term firm survival and growth. Yet, despite considerable academic interest, there are many questions about what dynamic capabilities (DCs) are, how they relate to other organizational operations, and how they relate to firm performance. In this article, we provide a unique and comprehensive examination of the DCV literature that goes beyond past reviews by combining text-based analysis with surveys of, and interviews with, researchers in the field. With this approach, we are able to examine the evolution of the DCV in written literature and identify missing research themes. Based on this review, we argue that future research will benefit from integrating the DCV with configuration theory and the recent micro foundational thinking. We encapsulate this discussion via an architectural model of the DCV (entitled “House of Dynamic Capabilities”) that combines micro foundations underlying DCs at the varying levels of analysis (individual, business unit, and organizational) while also accounting for important enablers of DCs and firm strategic orientation. We also show how this logic requires a completely different set of methodological approaches to those currently in use.

Social bonding and loneliness after network disruption: A longitudinal study of East German refugees

After the 1989 breakdown of the communist system, 235 East Germans were interviewed three times during the two years following their transition to West Berlin. In moving to the west, the migrants had to deal with various stressors, among them the lack of social ties in their new environment. Fortunately, the number of their new friends increased steadily, and loneliness declined. These changes, however, differed between sexes and age groups. Men made more friends than women, in particular same-sex friends, whereas women knitted ties with both sexes. The young built larger networks than the intermediate age group. Loneliness emerged as an inhibiting factor in the bonding process. The study demonstrates how well these refugees coped with a social crisis. It also examines the roles that loneliness and social bonding played in the readjustment process.     

Species change in an urban setting—ground and rove beetles (Coleoptera: Carabidae and Staphylinidae) in Berlin

The influence of environmental parameters on epigeic beetle communities of forest fragments in an urbanization gradient was studied in Berlin. Eight deciduous forests along a rural to urban gradient were sampled with pitfall traps. Species richness did not decline across the rural to urban gradient. As expected, impervious surface cover as an indicator of urbanization correlated not only with habitat fragmentation and heat island effect but also with altered soil properties. The proportion of forest specialist staphylinid species decreased with increasing urbanization. The differences between staphylinid communities of neighboring forest fragments were enhanced in the most urban parts, probably due to increased habitat fragmentation. Furthermore, the loss of flightless species with increasing habitat isolation emphasized the influence of habitat fragmentation. The carabid communities revealed the urbanization effects not as clearly as the staphylinid communities, but both taxa revealed that direct anthropogenic habitat alteration, indicated by removal of decaying wood, favors open-habitat specialists. The extent of the urbanization influence seems to vary seasonally. Environmental parameters associated with urbanization explain the ordination of species communities in the winter better than in the summer. Heat island effect is suggested as an explanation for this difference.     

Perseveration in Tool Use: A Window for Understanding the Dynamics of the Action‐Selection Process

Two experiments investigated how 3‐year‐old children select a tool to perform a manual task, with a focus on their perseverative parameter choices for the various relationships involved in handling a tool: the actor‐to‐tool relation and the tool‐to‐target relation (topology). The first study concerned the parameter value for the tool‐to‐target relation by asking how children use a cane for either pushing an object further away (exclosure; outside the hook) or pulling an object nearby (enclosure; inside the hook). The second study concerned the parameter value for the hand‐to‐tool relation by assessing the hand used for grasping a spoon to feed a puppet. Results from both studies showed that on the first trial, choices were driven by task information. However, when the task switched from pulling to pushing or from left hand to right hand, or vice versa, children persevered with the choice they made during the 4 previous trials. Results are discussed in terms of the dynamical field modeling work of Esther Thelen and her colleagues. Our findings underscore Thelen's hypotheses that: (a) the action‐selection process is a dynamic affair, affected by multiple influences at different time scales and its own intrinsic dynamics; and (b) that perseverative behavior is a general phenomenon that is neither indicative for a specific period in the development, nor for a particular task. Similarly, we argue that the presence (or absence) of causal understanding emerges from the action‐selection process, rather than determining this process.

Simulating competing cointegration tests in a bivariate system

In this paper, we consider the size and power of a set of cointegration tests in a number of Monte Carlo simulations. The behaviour of the competing methods is investigated in diff erent situations, including diff erent levels of variance and correlation in the error processes. The impact of violations of the common factor restriction (CFR) implied by the Engle-Granger framework is studied in these situations. The reactions to changes in the CFR condition depend on the error correlation. When the correlation is non-positive, the power increases with increasing CFR violations for the error correction model (ECM) test, while the other tests react in the opposite direction. We also note the reaction to diff erences in the error variances in the data-generating process. For positive correlation and equal variances, the reaction to changes in the CFR violations diff ers somewhat between the tests. We conclude that the ECM and the Z-tests show the best performance over diff erent parameter combinations. In most situations the ECM is best. Therefore, if we had to recommend a unit root test, it would be the ECM, especially for small samples. However, we do not think that one should use just one test, but two or more. Of course, the portfolio of tests we have considered here only represents a subset of the possible tests.
