Abstract We mainly study the block-coherence measures based on resource theory of block-coherence and the coherence measures based on positive-operator-valued measures (POVM). Several block-coherence measures including a block-coherence measure based on maximum relative entropy, the one-shot block coherence cost under the maximally block-incoherent operations, and a coherence measure based on coherent rank have been introduced and the relationships between these block-coherence measures have been obtained. We also give the definition of the maximally block-coherent state and describe the deterministic coherence dilution process by constructing block-incoherent operations. Based on the POVM coherence resource theory, we propose a POVM-based coherence measure by using the known scheme of building POVM-based coherence measures from block-coherence measures, and the one-shot block coherence cost under the maximally POVM-incoherent operations. The relationship between the POVM-based coherence measure and the one-shot block coherence cost under the maximally POVM-incoherent operations is analysed.

This study examined Korean companies on whether ownership affects corporate social responsibility performance (CSP) to influence on the corporate financial performance (CFP). According to the results, ownership has causational relationship with financial performance of firms varies upon proxy of CFP. Ownership and CFP demonstrates reverse-U type with ROA but U-type with market to book ratio (MB ratio). Second, ownership and CSP does not prove to have any causality. Partly, ownership shows negative effects on corporate governance. Finally, CSP does not affect profit (ROA) but improve the market value. For the moment, CSP is not an active factor to find out that high proportion of the companies in the sample during the research period were credited low CSP. Most of the companies with high credits on CSP are efficient and stable profit earning companies which leave room to consider the slack-resource theory.

While their power is declining, unions and workers remain prominent actors in society. Therefore, there is a need to bring power resource theory back to the analytical forefront in the study of contemporary labour politics and labour market sociology. It provides the analytical perspectives necessary for a comprehensive and historical understanding of labour markets and labour politics. However, this article argues that the original theory developed by Korpi needs to be reassessed and further developed. Revisiting the original theory and reviewing common criticism, the authors argue that power resource theory should pay closer attention to how different types of power resources are mobilised and used and how actors’ interests are shaped during that process. The article seeks to address these issues and thus move power resource theory forward and pave the way for future theorisation.

How does sleep affect employee effectiveness and what can employees do to remain effective on days with a lack of sleep? Drawing on the conservation of resources theory our research expands on the cognitive (regulatory resources), affective (positive affect), and motivational (subjective vitality) mechanisms that link sleep and employee effectiveness. Furthermore, considering the crucial role of individual beliefs in the spillover of sleep to work, we examine the moderating role of implicit theories about willpower – a mindset about the resource-draining nature of self-regulation – in the relation between sleep duration and employee effectiveness through regulatory resources availability. Two daily diary studies with a combined sample of Ntotal=214 employees (Ntotal=1317 workdays) demonstrate the predominant role of cognitive and affective resources in linking sleep at home to engagement, in-, and extra-role performance at work. Moreover, the spillover of sleep to employee effectiveness via cognitive resources is stronger for individuals holding a limited as compared to a non-limited resource theory. This research not only expands our theoretical understanding of the psychological mechanisms that link sleep to employee effectiveness but also offers practical implications by highlighting the protective role of holding a non-limited resource theory on days with a lack of sleep.
