We study how citation patterns differ between journal tiers in economics by analyzing citations patterns of more than 6,000 research articles published in top five, second tier, and top field economics journals. We find that top five journals' articles receive more citations and that the life cycles of those citations are longer. However, their influence (in term of citations) is overestimated: in its first twenty years since publication, the median top five article accumulates 4.25 as many citations when compared to non-top five median articles. This ratio is strongly associated with the field of economics research and with articles' impact. (JEL A14) 相似文献

Research of the last decades focused on answering several questions in view of optimum stimulation theory. Which variables do influence general explorative tendencies such as risk taking, variety seeking, or curiosity-motivated behaviour and how do the general explorative tendencies effect the willingness to choose new or familiar products on a repurchase occasion? The approach of this research is the attempt to analyse a wide range of variables, which have successfully been tested to influence innovative behaviour, within one simultaneous model. This research is applied across different product-categories. It is confirming the nomological validity of OSL-theory including some contextual variables by attesting a principal consistency between all (six) models that have been established throughout the range of several examined product categories. The parameters between inherent factors do not contradict when comparing the single models with each other, parameter values do only differ slightly according to category-specific peculiarities. As a consequence of these results, an overall fairly good picture is drawn of what is behind the keenness for innovations of early adopters in general (regardless of the product category). 相似文献

In this paper we argue that a systematic organizational consulting approach can be supportive in fostering innovation and change processes in companies. We discuss the consulting approach in three steps: First, we present a scientific meta-definition of the term “innovation”, which helps to identify the major challenges for companies in being innovative. Second, we raise urgent questions which companies have to face in order to address these major challenges. Third, we discuss tools from our organizational consulting experience that support companies in answering these questions on their way to innovation success, therefore providing a useful basis for innovation consulting. 相似文献

Empirical evidence shows that personnel selection methods positively contribute to the quality of the personnel selection process, which is one of the main fields of activity of personnel consultants. Unfortunately it is repeatedly mentioned in literature that selection methods could be implemented more efficiently. Personnel-consulting agencies and self-employed consultants bear a lot of responsibility regarding these aspects: they should recommend proven selection methods to their clients. In this article it is discussed how the selection process can achieve consistent quality. 相似文献

This meta-analysis examines the conditions under which structural and contextual approaches help balance exploration and exploitation. Drawing on heterogeneous samples of prior ambidexterity studies, we apply moderated meta-analytic regression methods to 33,492 organizations sampled in 114 primary studies from 1991 to 2017 to test a contingency model. Our findings suggest that structural separation helps firms of all sizes to balance exploration and exploitation, and that structural separation is more conducive for balancing exploration and exploitation in high technology environments. Also, avoiding a structural separation approach benefits service firms. As research on ambidexterity enters the maturity stage we discuss the implications for future theory development, methodology, and for managers interested in developing ambidextrous organizations. 相似文献

Although prior studies have consistently shown that organizational identification can reduce employees' stress and burnout, little is known about the mediating processes that underlie this relationship. Against this backdrop and building on recent theoretical work on the social identity model of stress, the present research tests a two-step mediation model for the organizational identification–burnout link. Specifically, it is hypothesized that employees who strongly identify with their organization are particularly likely to receive social support from their colleagues. This, in turn, should promote a sense of collective efficacy and, as a consequence, negatively relate to burnout. Data from a study with 192 Italian high schoolteachers supported the hypotheses. 相似文献

This paper examines the post-divestiture behavior of spun-off firms. Drawing on the spin-off literature and middle-status conformity theory, we argue that spun-off firms—as newly independent and publicly traded firms—tend to limit their risk-taking behavior to match the expectations of a crucial audience, i.e., security analysts. Following the logic of middle-status conformity theory, we hypothesize that firms with mid-level status are particularly susceptible to analysts' pressures, whereas high- and low-status firms are free to take greater risks. Crucially, however, we propose that this relationship is less pronounced for spun-off firms that are more attached to their parent firms, as formal and informal linkages between these two types of firms can endure beyond the separation and limit spun-off firms' independence. Using a dataset of 102 spin-off transactions occurring between 1995 and 2010, we find empirical support for a U-shaped relationship between spun-off firms' status and risk-taking. This relationship is attenuated when spun-off firms are more attached to their parents. We contribute to the spin-off literature by demonstrating that a spun-off firm's post-divestiture behavior is determined by the capital market audience's expectations and the attachment to the parent firm. In so doing, we also contribute to the literature on middle-status conformity theory by identifying a boundary condition of the theory. Additionally, we make a methodological contribution by combining ideas from the spin-off and institutional theory literature to develop a particularly comprehensive measure of attachment. 相似文献

Based on a cost-reduction argument, this study explored whether anticipated childcare support from their mothers influenced adult daughters’ decisions to have their first child. Using six waves of the German Family Panel (pairfam), discrete-time hazard models (N = 3155 women) were estimated for the transition to the decision to have the first child. Anticipated childcare support from the women’s mothers was approximated by the travelling distance between adult daughters and their mothers, a measure whose suitability was tested empirically. The results indicated that women in a position to anticipate having access to childcare support in the future decided to make the transition to parenthood earlier. This finding highlights both the strength of social interaction effects on fertility decision-making and the importance of intergenerational relationships for individual fertility histories already at their very beginning. 相似文献

In first-level analyses of functional magnetic resonance imaging data, adjustments for temporal correlation as a Satterthwaite approximation or a prewhitening method are usually implemented in the univariate model to keep the nominal test level. In doing so, the temporal correlation structure of the data is estimated, assuming an autoregressive process of order one.We show that this is applicable in multivariate approaches too - more precisely in the so-called stabilized multivariate test statistics. Furthermore, we propose a block-wise permutation method including a random shift that renders an approximation of the temporal correlation structure unnecessary but also approximately keeps the nominal test level in spite of the dependence of sample elements.Although the intentions are different, a comparison of the multivariate methods with the multiple ones shows that the global approach may achieve advantages if applied to suitable regions of interest. This is illustrated using an example from fMRI studies. 相似文献
