Hierarchical One-Class Model With Subnetwork for Representation Learning and Outlier Detection.

The multilayer one-class classification (OCC) frameworks have gained great traction in research on anomaly and outlier detection. However, most multilayer OCC algorithms suffer from loosely connected feature coding, affecting the ability of generated latent space to properly generate a highly discriminative representation between object classes. To alleviate this deficiency, two novel OCC frameworks, namely: 1) OCC structure using the subnetwork neural network (OC-SNN) and 2) maximum correntropy-based OC-SNN (MCOC-SNN), are proposed in this article. The novelties of this article are as follows: 1) the subnetwork is used to build the discriminative latent space; 2) the proposed models are one-step learning networks, instead of stacking feature learning blocks and final classification layer to recognize the input pattern; 3) unlike existing works which utilize mean square error (MSE) to learn low-dimensional features, the MCOC-SNN uses maximum correntropy criterion (MCC) for discriminative feature encoding; and 4) a brand-new OCC dataset, called CO-Mask, is built for this research. Experimental results on the visual classification domain with a varying number of training samples from 6131 to 513 061 demonstrate that the proposed OC-SNN and MCOC-SNN achieve superior performance compared to the existing multilayer OCC models.

Studying Entrepreneurship-as-Practice Visually: Data Strategies and Analytical Considerations.

The objective of this essay is to forge a more explicit link between the "visual turn" and the "practice turn" in entrepreneurship research. Specifically, we explore three key aspects of mobilizing visual methods for studying entrepreneurship-as-practice (EaP), i.e., data sources, collection strategies, and analytical perspectives, highlighting the important theoretical and empirical promises that visual methods hold for said research. This essay bears implications for researchers and educators working at the intersection of entrepreneurship research, the practice theory, and visual methods.

Symbolic Convergence or Divergence? Making Sense of (the Rhetorical) Senses of a University-Wide Organizational Change.

This research investigates the extent to which organizational change initiatives may lead to divergent patterns of sensemaking among organizational members. Drawing on the symbolic convergence theory, we performed an in-depth fantasy theme analysis of organization members' rhetoric around an organizational change at a private university. Our analysis uncovers six fantasy themes and two corresponding fantasy types, which lead to no rhetorical vision. The lack of cognitive convergence between change initiators and change recipients suggests the inherent incompatibility between managerial and employee fantasies around organizational change, barring the exceptions of dual-responsibility change recipients (e.g., faculty members who also assume administrative responsibilities), who tend to adopt the change initiator rhetoric. Overall, this study informs our extant knowledge of change sensemaking with novel theoretical and methodological insights and bears implications for organizational change researchers and practitioners alike.

Family Embeddedness and Medical Students' Interest for Entrepreneurship as an Alternative Career Choice: Evidence From China.

Joining the ongoing academic debates around medical students' alternative career choices, this research examines the role of family in medical school attendees' entrepreneurial intention (EI). Specifically, this study decomposes the multidimensionality of family embeddedness and highlights the mediated nature of the family-EI relationship. The empirical analysis relied on data from graduation year medical students from diverse geographical locations and from different institution types in China. These data were collected from a total of 687 questionnaires covering the basic information of individual, parents, and family composition, as well as the measuring scale of EI. Examining medical students' EI and its antecedents provide a dual-missing-link in the extant knowledge, i.e., it adds the medical school piece to the overall picture of university students' EI, and equally important, it de-trivializes entrepreneurship from the extant theorizations of medical students' career choices. This study also bears implications for educators, practitioners, and policymakers interested in better understanding EI of medical school attendees and family embeddedness.
