Resolving the Artisan Entrepreneur’s Oppositional Identity With Venturing in a Declining City Context

This article presents conceptual research questions and propositions on the relationship between the artisan entrepreneur’s oppositional identity and entrepreneurially venturing in the context of declining cities and urbanized regions. In general, I propose that some features of declining cities typically deemed harmful to business (e.g., deindustrialization, population loss, stifled innovation) may be less problematic for artisan ventures operated with a strong devotion to craft, localness and sense of place, and independence and less emphasis on financial performance than is typical of more mainstream entrepreneurship. The conceptual development herein relies on identity theory (including occupational identity and counter-institutional identity concepts), embeddedness theory, and urban economics concepts. This effort addresses calls for more research on both artisan entrepreneurship and the declining city as a context of entrepreneurship

Impact of Socialization in Elderly Public-Housing Residents

Older adults who experience social isolation have higher rates of mortality relative to their counterparts. Social interactions are an important way to combat this isolation. This research aims to better understand how social isolation in older adults living in low-income households in Richmond, Virginia (RVA) is related to their economic, physical, and psychological health status. As part of the iCubed Health and Wellness Aging Core and in collaboration with the Richmond Memorial: East End Housing Coalition for Older Adults, older adults from a selected public housing unit (n=28) self-reported their financial status, experiences with physical and psycho-social health, and feelings of social isolation. Survey participants were 71.4% female, the mean age was 69.75 years, and 25% were high school graduates. Participants averaged 34 years living in the East End and reported an average of $300 to spend on rent monthly. Overall, 55% (n=20) reported having two or more supports and 61% (n=22) reported hardly ever feeling isolated. However, a small subset of the sample reported having either no supports (5.6%, n=2) and 41.7% (n=15) lacked companionship some of the time or often. A one-way ANOVA was conducted and it was determined that participants who reported feeling left out more often were significantly more likely to report stress, anxiety, and depression (F[2, 25] = 6.998). Findings support the existence of supportive communities formed in low-income areas. Findings also indicate some older individuals residing in public housing in RVA experience social isolation and that this status is linked to poorer psycho-social health.https://scholarscompass.vcu.edu/gradposters/1048/thumbnail.jp

THREE-DIMENSIONAL COMPARISON OF SELECTED KINEMATICS BETWEEN MALE AND FEMALE INTERCOLLEGIATE JAVELIN THROWERS

The purpose of the study was to compare ROM, peak angular acceleration and percent throw values of peak angular acceleration of the upper arm, trunk, and pelvis segments, and elbow and knee joints between skilled male and female javelin throwers. Nine male and 11 female intercollegiate javelin throwers (n = 20) were videotaped using 2 120 Hz cameras. PEAK5 Motion Measurement System was used to analyze the data. Hotelling’s T2 tests revealed no significant differences (p > .01). However, females did appear to use the lower extremity differently by producing large amounts of pelvis ROM, pelvis peak angular acceleration, and knee extension peak angular accelerations. Both groups exhibited the proximal to distal sequencing of accelerations with the exception of upper arm internal rotation

Chronic Underfit of the Small Firm’s HRM Function: When Low Functional Elaboration Interacts with Contingencies

We address qualitative functional elaboration of human resource management (HRM) in small firms where HRM is typically simple and informal. After describing qualitative functional elaboration in terms of structuration, managerial process, and effects on HRM, we discuss relevant contingencies that can render small-firm HRM’s degree of elaboration insufficient relative to firm needs and goals. We then discuss implications of chronic underfit of HRM in small firms, drawing on theory of asymmetric effects of misfit. Finally, we discuss implications for future research, practice, and entrepreneurship education
