A tale of two regions: Novgorod and Pskov as models of symbolic development

Russian regions display remarkably different patterns of economic and political development. These differences come into sharp focus when comparing two nearly identical northwestern regions, Novgorod and Pskov. Novgorod's success and Pskov's failure are attributed to the local elite's creative use of key cultural symbols and myths to support regional development. Contrasting two popular approaches to culture and development—“cultural adjustment” and “cultural congruence”—the author argues that the cultural congruence model, adopted by Novgorod, dramatically improves the chances for rapid social and economic transformation.     

Testing for lack of fit in inverse regression—with applications to biophotonic imaging

Summary.  We propose two test statistics for use in inverse regression problems Y = K θ + ɛ , where K is a given linear operator which cannot be continuously inverted. Thus, only noisy, indirect observations Y for the function θ are available. Both test statistics have a counterpart in classical hypothesis testing, where they are called the order selection test and the data-driven Neyman smooth test. We also introduce two model selection criteria which extend the classical Akaike information criterion and Bayes information criterion to inverse regression problems. In a simulation study we show that the inverse order selection and Neyman smooth tests outperform their direct counterparts in many cases. The theory is motivated by data arising in confocal fluorescence microscopy. Here, images are observed with blurring, modelled as convolution, and stochastic error at subsequent times. The aim is then to reduce the signal-to-noise ratio by averaging over the distinct images. In this context it is relevant to decide whether the images are still equal, or have changed by outside influences such as moving of the object table.     

Fuzziness in Action: What Consequences Has the Linguistic Ambiguity of the Core Competence Concept for Organizational Usage?

Linguistic ambiguity is one of the most prominent characteristics of management fashions. Using the example of one of the most popular management concepts in the 1990s, the core competence approach, we analyse the consequences of linguistic ambiguity on the level of organizational usage. We pursue an in‐depth case study of a German corporation which can be seen as a ‘heavy adopter’ of the core competence concept. A central implication of our study is that the term ‘ambiguity’ itself has several meanings depending on the level of analysis. On a general level the managers interpreted the core competence concept relatively homogeneously. They simplified and generalized it to an organizational principle and perceived it as guiding action. At the same time, each manager defined his or her own set of core competences. Thus, underneath a seeming consensus, a large variety of practices may hide. This novel kind of ‘contextual ambiguity’ does not originate from the linguistic ambiguity of the management fashion but from the plurality of local contexts in which the concept is interpreted. The managers' pragmatic attitude to the core competence ‘principle’ contributed to the high contextual ambiguity and the – compared to the media discourse – high longevity of the fashion within the case company. Our findings urge management fashion scholars to pay more attention to the distributed and polyphonic character of organizations and the organizational nature of the ‘consumption’ of ambiguous management knowledge.     

Integrationstandems und Supervised Networking mit geflüchteten Menschen in studentischen Gruppen durch Service LearningIntegration Tandems and Supervised Networking with Refugees in Student Groups through Service Learning

This contribution reports on a pilot project which took place during the winter semester 2015/16 at the University of Göttingen based on the concept of Service Learning. As part of service learning, students assume practical tasks from the social environment and apply academic knowledge. With this new didactical approach, personality development of the students as well as civil and democratic values in society should be enhanced.     

Estimation of a quadratic regression functional using the sinc kernel

We use the sinc kernel to construct an estimator for the integrated squared regression function. Asymptotic normality of the estimator at different rates is established, depending on whether the regression function vanishes or not.     

On difference-based variance estimation in nonparametric regression when the covariate is high dimensional

Summary.  We consider the problem of estimating the noise variance in homoscedastic nonparametric regression models. For low dimensional covariates t  ∈  R ^d ,  d =1, 2, difference-based estimators have been investigated in a series of papers. For a given length of such an estimator, difference schemes which minimize the asymptotic mean-squared error can be computed for d =1 and d =2. However, from numerical studies it is known that for finite sample sizes the performance of these estimators may be deficient owing to a large finite sample bias. We provide theoretical support for these findings. In particular, we show that with increasing dimension d this becomes more drastic. If d 4, these estimators even fail to be consistent. A different class of estimators is discussed which allow better control of the bias and remain consistent when d 4. These estimators are compared numerically with kernel-type estimators (which are asymptotically efficient), and some guidance is given about when their use becomes necessary.     

Present-but-online: How mobile devices may harm purposeful co-presence in organizations (and what can be done about it)

The introduction of mobile devices (e.g., smartphones and tablets), to the workplace has had many positive effects. While research also indicates that mobile devices may lead to the misallocation and depletion of attention, the negative effects, particularly on interactions in organizations, remain less well understood. We draw on micro-sociology to analyze the use of mobile devices in situations of purposeful co-presence, such as meetings and settings that require a joint effort to solve one or more problems. In these situations, the use of mobile devices is likely to de-energize actors and lead to behaviors that are contrary to the aims of establishing situations of purposeful co-presence. We identify ways in which organizations can avoid the negative consequences of mobile devices (while keeping the positive consequences), ranging from building norms regarding the use of such devices to restructuring work processes (e.g., making activities less interdependent and making less use of purposeful co-presence).     

Business models and business model innovation: Between wicked and paradigmatic problems

While research on business models and business model innovation continue to exhibit growth, the field is still, even after more than two decades of research, characterized by a striking lack of cumulative theorizing and an opportunistic borrowing of more or less related ideas from neighbouring fields in the place of cumulative theory. We argue that the lack of cumulativeness stems from lack of construct clarity (i.e., BM and BMI are seldom defined with much precision) and lack of agreement on definitions, which in turn imply that the core constructs are not dimensionalized in a way that eases theory-building and empirical testing. Lack of progress on these matters partly reflect that the BM and BMI constructs are used in multiple explanatory contexts, so that it is not entirely clear what are the problems that BM and BMI research seek to solve. We argue, with Teece (2010), that the BM and BMI constructs are fundamentally about the architecture of the firm's value creation, delivery and capture mechanisms; theoretically the key aspect of BMs is complementarity between activities underlying these mechanisms; BMI means novel changes of such complementary relations; and this understanding not only unifies diverse contributions to the literature but is also productive of new insight.     

The Relational Antecedents of Interpersonal Helping: ‘Quantity’, ‘Quality’ or Both?

Having a large network of colleagues means having several opportunities to help those colleagues, as well as a higher chance of receiving requests for help from them. Employees with large networks are therefore expected to help more in the workplace than those with small networks. However, large networks are also associated with cognitive costs, which may reduce the focal employee's ability to both recognize the need for help and engage in helping behaviours. For these reasons, the authors assert an inverted U‐shaped relation between the size of an ego's social network and engagement in helping behaviour. However, high‐quality relationships imply higher mutual understanding between the actors, and hence lower cognitive costs. In turn, the position (and threshold) of the curve between network size and interpersonal helping should be influenced by the quality of the relationship between the provider and the beneficiaries of help. Analysis of employee‐level, single‐firm data supports these ideas, providing preliminary evidence that quality of relationship compensates for the difficulties that may arise from having large social networks.     

Knowledge and Organization in the Theory of the Multinational Corporation: Some Foundational Issues

This paper addresses the interaction of knowledge and organization in IB research, particularly research on the MNC. The argument is advanced that although the MNC literature is quite advanced with respect to its treatment of firm-level knowledge, several closely connected problems remain. In particular, there has been an over-emphasis on knowledge flows and an under-emphasis on knowledge stocks; the micro-foundations of MNC knowledge are unclear; and there is a no clear understanding of the causal relations between knowledge stocks and flows and organizational control. A control theory approach that may resolve some of these problems is then sketched.
