Identification (a state of perceived "oneness" with a given target) fulfills fundamental human motives and facilitates a range of positive outcomes, but it also has a dark side. While detrimental effects of identification in organizations have been captured in various studies, the field of management lacks a comprehensive blueprint of the state of this research. This omission is particularly significant given recent calls for some "course corrections" in the field, which signal the need to balance the dominant preoccupation with the positive effects of identification and identity with more consideration of their negative effects. It is also a missed opportunity for impact given the relevance of the topic to understanding current identity-related tensions and issues within organizations (e.g., debates around diversity and inclusion). We address this oversight with a comprehensive review of the dark side of strong identification, focusing specifically on exclusive, mixed, and multiple identifications. In doing so, we highlight the need for a more balanced understanding of the ways identification processes influence our lives, organizations, and society at large. [ABSTRACT FROM AUTHOR]

Magnetic skyrmions are exciting candidates for energy-efficient computing due to their nonvolatility, detectability, and mobility. A recent proposal within the paradigm of reversible computing enables large-scale circuits composed of directly cascaded skyrmion logic gates, but it is limited by the manufacturing difficulty and energy costs associated with the use of notches for skyrmion synchronization. To overcome these challenges, we, therefore, propose a skyrmion logic synchronized via modulation of voltage-controlled magnetic anisotropy (VCMA). In addition to demonstrating the principle of VCMA synchronization through micromagnetic simulations, we also quantify the impacts of current density, skyrmion velocity, and anisotropy barrier height on skyrmion motion. Further micromagnetic results demonstrate the feasibility of cascaded logic circuits in which VCMA synchronizers enable clocking and pipelining, illustrating a feasible pathway toward energy-efficient large-scale computing systems based on magnetic skyrmions.

For better or worse, contemporary society places immense value on achievement and performance. What are the consequences of this emphasis on (if not obsession with) performance for people's sense of self, and relatedly, their mental health and well-being? We develop a theoretical lens for exploring such questions by introducing the concept of performance-based identity—a form of identity that we propose arises when performance (at work or in another setting) becomes personally meaningful to the extent that it acts as a basis for self-definition. We argue that many individuals are likely to develop performance-based identities in a world where performance is increasingly emphasized as important, and where other identities (e.g. those derived from particular groups, organizations, and cultures) are being destabilized by fundamental shifts in the nature of work and society. We explain the similarities and differences between performance-based identity and related constructs, present a theoretical account of how people construct performance-based identities, and discuss how acknowledging and studying performance-based identities could yield valuable new insights into how people experience their work and life in general.

Introduced mammals have devastated island nesting seabird populations worldwide. Declines in breeding seabirds on St Kilda, UK, have been linked to climate change and predation from great skuas Stercorarius skuas, but the introduced St Kilda field mouse Apodemus sylvaticus hirtensis may also play a role by feeding on adults, chicks or eggs. Here, we use stable isotopes in St Kilda mouse blood and potential dietary items to investigate their foraging ecology, specifically focussing on the importance of seabirds and marine foods in their diet. Mice were seasonally sampled at three sites on Hirta, St Kilda over three consecutive years (2010–2012). The δ13C and δ15N ratios were used in analyses, including isotope niche and dietary source mixing models, to examine foraging behaviour among locations and between seabird breeding seasons. Mice sampled in Carn Mor – where the majority of the island's seabirds nest - had consistently higher δ13C than other locations throughout the year, with δ15N also being significantly higher for all but one comparison. The isotopic niche width (SEAs) of Carn Mor mice in each season were distinct from the other locations, and became smaller during the seabird breeding season. Dietary mixing models revealed that seabirds made up a large proportion of the diet for mice from Carn Mor, particularly during the seabird breeding season. In conclusion, our work reveals that seabird-derived foods are likely to form a significant part of the diet of St Kilda mice populations located in and around breeding colonies. It is unclear however, whether this is from scavenging or predation of seabirds, or through their discarded food items. Given that mice have had significant effects on seabird populations elsewhere, it is important to carry out further work to determine whether mice are a significant cause of seabird mortality in this island ecosystem.
