This article contributes to the ongoing debate on the economic determinants of fertility behavior by addressing the role of
job insecurity in couples’ intentions concerning parenthood and its timing. It starts from the hypothesis that cultural values
moderate individuals’ reactions to job insecurity and the way it is related to family formation. With a systematic thematic
content analysis of a set of semi-structured interviews with childless men and women around the age of 30 in eastern and western
Germany, we are able to show that there are substantial differences in the consequences of job insecurity on intentions to
have a first child. In western Germany, a relatively secure job career is expected to precede family formation, and this sequence
of transitions is rather rigid, whereas in eastern Germany job security and family formation are thought of and practiced
as parallel investments. We suggest that the lack of convergence in family formation patterns between eastern and western
Germany after the unification of the country in 1990 is partially related to different attitudes toward job insecurity in
the two contexts. 相似文献

The extant literature highlights numerous different factors influencing the timeliness and intensity of incumbent response
to discontinuous technological change. However, this literature has so far not been synthesized and is therefore limited in
its analytical, predictive, and normative power. We develop a comprehensive model of incumbent response that organizes different
explanatory factors into the three distinct dimensions of (1) identification and interpretation, (2) decision making, and
(3) organizational implementation. We also conceptualize how response intensity and timeliness affect business performance
in new technological domains. We test the model against data from 320 firms from the German dental lab industry, finding substantial
support for the majority of our hypotheses. This study offers unique empirical insight in observing that cognitive constructs
such as framing and management flexibility have the strongest impact on both intensity and timeliness of incumbent response
to technological, and thus, strategic discontinuities. Together, our findings have important implications for both theory
and practice. 相似文献

Entrepreneurial activity unfolds in a dynamic environment that challenges business viability. We utilize grounded theory as a novel type of reflection to explain and interpret whether and how innovation can afford survival benefits to firms. The premise is the application of a methodological approach with reflexive properties to advance scientific rigor in “reflections.” The idea underlying our reflection was to use innovation as the point of departure, review the literature, conceptualize ideas, and finally link the concepts that emerged as components of a framework. Our view of the firm resembles a viable entity that changes, constantly striving to meet and balance internal potentials and external complexities, while innovation per se involves change that is made possible by entrepreneurship. We bring together our personal and professional backgrounds and implement the European scholarly tradition on innovation and Viable Systems approach to scrutinize innovation’s interactions and relations. We linked boundary conditions, opportunities, and complementary assets to innovation. Effectively, our analysis conceptualizes innovation as autopoiesis in entrepreneurship and demonstrates its central role as the vehicle to exploit changes that ensure firm viability. 相似文献

Insights into the dynamics of human behavior in response to flooding are urgently needed for the development of effective integrated flood risk management strategies, and for integrating human behavior in flood risk modeling. However, our understanding of the dynamics of risk perceptions, attitudes, individual recovery processes, as well as adaptive (i.e., risk reducing) intention and behavior are currently limited because of the predominant use of cross-sectional surveys in the flood risk domain. Here, we present the results from one of the first panel surveys in the flood risk domain covering a relatively long period of time (i.e., four years after a damaging event), three survey waves, and a wide range of topics relevant to the role of citizens in integrated flood risk management. The panel data, consisting of 227 individuals affected by the 2013 flood in Germany, were analyzed using repeated-measures ANOVA and latent class growth analysis (LCGA) to utilize the unique temporal dimension of the data set. Results show that attitudes, such as the respondents’ perceived responsibility within flood risk management, remain fairly stable over time. Changes are observed partly for risk perceptions and mainly for individual recovery and intentions to undertake risk-reducing measures. LCGA reveal heterogeneous recovery and adaptation trajectories that need to be taken into account in policies supporting individual recovery and stimulating societal preparedness. More panel studies in the flood risk domain are needed to gain better insights into the dynamics of individual recovery, risk-reducing behavior, and associated risk and protective factors. 相似文献

Bayesian statistical inference relies on the posterior distribution. Depending on the model, the posterior can be more or less difficult to derive. In recent years, there has been a lot of interest in complex settings where the likelihood is analytically intractable. In such situations, approximate Bayesian computation (ABC) provides an attractive way of carrying out Bayesian inference. For obtaining reliable posterior estimates however, it is important to keep the approximation errors small in ABC. The choice of an appropriate set of summary statistics plays a crucial role in this effort. Here, we report the development of a new algorithm that is based on least angle regression for choosing summary statistics. In two population genetic examples, the performance of the new algorithm is better than a previously proposed approach that uses partial least squares. 相似文献

The CCR model by Charnes et al. (Eur J Oper Res 2:429–444, 1978) together with the BCC model by Banker et al. (Manag Sci 30:1078–1091, 1984) are the most popular approaches of measuring efficiency among a group of decision making units, DMUs, in data envelopment analysis, DEA. The right choice of a DEA model—CCR or BCC—often, if not always, is a difficult decision. To evaluate a DMU’s efficiency for both models might be helpful, but it does not always capture the essential issues at stake. In this paper we propose a comparative analysis of both concepts: How does activity scaling under constant BCC-efficiency influence CCR-efficiency. And inversely, how does BCC-efficiency behave when activity scaling under constant CCR-efficiency is applied. Such findings of mutual effects improve a DMU’s ability to reassess upsizing and downsizing of activities. Moreover, it allows for exact calculations of the resulting economic effects, and these effects give new insights beyond classical DEA. Finally, scale efficiency turns out to be the ideal concept to control these activity changes, rather than just CCR- or BCC-efficiency. We use a little numerical example to emphasize advantages of the new concept and sketch the new findings for a theater scenery. 相似文献
