Personal Lives? The Effects of nonwork behaviors on organizational image
Cataloged from PDF version of article.Organizational leaders may respond to employee nonwork behaviors because of the possible
influence on organizational image. We describe a typology of nonwork behaviors and discuss their
potential implications for organizational image. We explore conditions under which organizational
leaders may attempt to control employee nonwork behaviors and review the available alternatives
for organizational control. We conclude by discussing the theoretical and practical implications of
research on nonwork behavior
Complex Propagation Patterns Characterize Human Cortical Activity during Slow-Wave Sleep
Cortical electrical activity during nonrapid eye movement (non-REM) sleep is dominated by slow-wave activity (SWA). At larger spatial scales (similar to 2-30 cm), investigated by scalp EEG recordings, SWA has been shown to propagate globally over wide cortical regions as traveling waves, which has been proposed to serve as a temporal framework for neural plasticity. However, whether SWA dynamics at finer spatial scales also reflects the orderly propagation has not previously been investigated in humans. To reveal the local, finer spatial scale (similar to 1-6 cm) patterns of SWA propagation during non-REM sleep, electrocorticographic (ECoG) recordings were conducted from subdurally implanted electrode grids and a nonlinear correlation technique [mutual information (MI)] was implemented. MI analysis revealed spatial maps of correlations between cortical areas demonstrating SWA propagation directions, speed, and association strength. Highest correlations, indicating significant coupling, were detected during the initial positive-going deflection of slow waves. SWA propagated predominantly between adjacent cortical areas, albeit spatial noncontinuities were also frequently observed. MI analysis further uncovered significant convergence and divergence patterns. Areas receiving the most convergent activity were similar to those with high divergence rate, while reciprocal and circular propagation of SWA was also frequent. We hypothesize that SWA is characterized by distinct attributes depending on the spatial scale observed. At larger spatial scales, the orderly SWA propagation dominates; at the finer scale of the ECoG recordings, non-REM sleep is characterized by complex SWA propagation patterns
Understanding and tackling societal grand challenges through management research
“Grand challenges” are formulations of global problems that can be plausibly addressed through coordinated and collaborative effort. In this Special Research Forum, we showcase management research that examines societal problems that individuals, organizations, communities, and nations face around the world. We develop a framework to guide future research to provide systematic empirical evidence on the formulation, articulation, and implementation of grand challenges. We highlight several factors that likely enhance or suppress the attainment of collective goals, and identify representative research questions for future empirical work. In so doing, we aspire to encourage management scholars to engage in tackling broader societal challenges through their collaborative research and collective insight
Corporate governance and financial constraints on strategic turnarounds
The paper extends the Robbins and Pearce (1992) two-stage turnaround response model to include governance factors. In addition to the retrenchment and recovery, the paper proposes the addition of a realignment stage, referring specifically to the re-alignment of expectations of principal and agent groups. The realignment stage imposes a threshold that must be crossed before the retrenchment and hence recovery stage can be entered. Crossing this threshold is problematic to the extent that the interests of governance-stakeholder groups diverge in a crisis situation. The severity of the crisis impacts on the bases of strategy contingent asset valuation leading to the fragmentation of stakeholder interests. In some cases the consequence may be that management are prevented from carrying out turnarounds by governance constraints. The paper uses a case study to illustrate these dynamics, and like the Robbins and Pearce study, it focuses on the textile industry. A longitudinal approach is used to show the impact of the removal of governance constraints. The empirical evidence suggests that such financial constraints become less serious to the extent that there is a functioning market for corporate control. Building on governance research and turnaround literature, the paper also outlines the general case necessary and sufficient conditions for successful turnarounds
Do the type and number of blockholders influence R&D investments? : new evidence from Spain
Using data from 3,638 Spanish firms between 1996 and 2000, this article studies the relationship between the presence of large shareholders in the ownership structure of firms and R&D investment. Consistent with our theoretical contention, our results indicate that the impact of large shareholders on the R&D investment is (1) negative when blockholders are banks, (2) positive when blockholders are non-financial corporations and (3) null when blockholders are individuals. In addition, we find a systematic negative relationship between the number of blockholders and R&D investment. Finally, we extend our study by analysing the influence that the combined effect between blockholder type and R&D investment has on the firm’s economic performance. Results of this work provide relevant implications for policy makers and academic research.Publicad
Antecedents and consequences of effectuation and causation in the international new venture creation process
The selection of the entry mode in an international market is of key importance for the venture. A process-based perspective on entry mode selection can add to the International Business and International Entrepreneurship literature. Framing the international market entry as an entrepreneurial process, this paper analyzes the antecedents and consequences of causation and effectuation in the entry mode selection. For the analysis, regression-based techniques were used on a sample of 65 gazelles. The results indicate that experienced entrepreneurs tend to apply effectuation rather than causation, while uncertainty does not have a systematic influence. Entrepreneurs using causation-based international new venture creation processes tend to engage in export-type entry modes, while effectuation-based international new venture creation processes do not predetermine the entry mod
The genetic legacy of the Hunyadi descendants
The Hunyadi family is one of the most influential families in the history of Central Europe in the 14th–16th centuries. The family’s prestige was established by Johannes Hunyadi, a Turk-beater who rose to the position of governor of the Kingdom of Hungary. His second son, Matthias Hunyadi, became the elected ruler of the Kingdom of Hungary in 1458. The Hunyadi family had unknown origin. Moreover, Matthias failed to found a dynasty because of lacking a legitimate heir and his illegitimate son Johannes Corvinus was unable to obtain the crown.
His grandson, Christophorus Corvinus, died in childhood, thus the direct male line of the family ended. In the framework of on interdisciplinary research, we have determined the whole genome sequences of Johannes Corvinus and Christophorus Corvinus by next-generation sequencing technology. Both of them carried the Y-chromosome haplogroup is E1b1b1a1b1a6a1c ~, which is widespread in Eurasia. The father-son relationship was verified using the classical STR method and whole genome data. Christophorus Corvinus belongs to the rare, sporadically occurring T2c1Ăľ146 mitochondrial haplogroup, most frequent around the Mediterranean, while his father belongs to the T2b mitochondrial haplogroup, widespread in Eurasia, both are consistent with the known origin of the mothers. Archaeogenomic analysis indicated that the Corvinus had an ancient European
genome composition.
Based on the reported genetic data, it will be possible to identify all the other Hunyadi family member, whose only known grave site is known, but who are resting assorted with several other skeletons

Shareholder activism in the UK: types of activists, forms of activism, and their impact on a target’s performance
Considering the recent rapid expansion of shareholder activism phenomenon in the United Kingdom (UK) and the vast amount of resources committed to it by corporations, government and investors, its effectiveness has become a crucial subject for investigation. This article analyzes organizational outcomes of shareholder activism in the UK. This research is based on a unique comprehensive database of shareholder activism events during the period of 1998–2008. We provide a detailed account of different types of activists, activism strategies and shareholder demands associated with the events of activism. Our findings show that the effectiveness of shareholder activism in terms of abnormal stock-market returns varies dramatically depending on its form, type of investor and the nature of investor proposals
