Entrepreneurship in a Hub-and-Spoke Industrial District: Firm Survey Evidence from Seattle's Technology Industry

Mayer H. Entrepreneurship in a hub-and-spoke industrial district: firm survey evidence from Seattle's technology industry, Regional Studies. The paper investigates entrepreneurial dynamics in a hub-and-spoke industrial district. Using data on the genealogy of high-technology firms in Seattle, Washington State, the study examines the ways in which entrepreneurial firms relate to their parent firms and the role of agglomeration economies. The results illustrate that entrepreneurship is an important vehicle for the diversification of such a district. When compared, hub-related spinoffs such as those founded by former Microsoft employees do not differ much from other start-ups. The differences between Microsoft spinoffs and start-ups are very limited; both diversify the regional economy by entering new markets when compared with their parents.

Momentan verfügbare Selbstkontrollkraft: Vorstellung eines Messinstruments und erste Befunde aus pädagogisch-psychologischen Kontexten

Selbstkontrolle spielt in pädagogischen Kontexten oft eine entscheidende Rolle, beispielsweise wenn Lernende attraktiven Handlungsalternativen widerstehen müssen. Etliche Studien zeigen, dass die erfolgreiche Ausübung von Selbstkontrolle von der momentanen Verfügbarkeit an Selbstkontrollkraft abhängt. Zur Erfassung der momentanen Selbstkontrollkraft in deutschsprachigen Stichproben, wurde die State Self-Control Capacity Scale ins Deutsche adaptiert. In der vorliegenden Arbeit wird über fünf Teilstudien berichtet, in denen die psychometrische Güte dieser Skala überprüft wurde. Über alle Studien hinweg erwies sich die eindimensionale Skala als sehr reliabel (Cronbachs Alphas ≥ .93). Bezüglich ihrer Validität zeigten sich erwartete Zusammenhänge mit Validitätskriterien (z. B. Angst, Stress, am gegenwärtigen Tag bereits in Lehrveranstaltungen verbrachte Zeit); zusätzlich gelang die empirische Trennung von verschiedenen Stimmungsaspekten. Des Weiteren bildete die neue Skala (quasi-) experimentell im Labor und im Feld (Hochschule) induzierte Unterschiede in der Selbstkontrollkraft ab. Auch eine aus zehn Items bestehende Kurzskala erwies sich als hinreichend reliabel und valide.

Self-control strength in the relation between trait test anxiety and state anxiety

The present research examined whether in a test situation, the relation between trait test anxiety and state anxiety depends on the momentary availability of self-control strength. Since self-control strength is crucial for emotion regulation, we assume that trait test anxiety is more closely related to state anxiety if self-control strength is depleted than if it is not depleted. We conducted an experiment with 119 undergraduates in which we measured trait test anxiety, manipulated availability of self-control strength, and assessed state anxiety after a test announcement. Consistent with the assumption, multiple regression analyses revealed that trait test anxiety and state anxiety were positively related if self-control strength was depleted, but were not related if self-control strength was intact.

Too exhausted for Operation? Anxiety, depleted self-control strength, and perceptual-motor performance

We tested the hypothesis that the interaction of self-control strength and state anxiety predicts perceptual–motor performance in a hand–eye coordination task. We predicted a stronger negative relation between anxiety and performance in a perceptual–motor task for participants whose self-control strength had been temporarily depleted compared to participants whose self-control strength was intact. In an experiment (N = 60), we manipulated self-control strength, measured state anxiety after an evaluative instruction, and assessed performance in the board game Operation as an indicator of perceptual–motor performance. The data supported our hypothesis: Only for participants whose self-control strength was temporarily depleted was there a statistically significant negative relation between anxiety and performance. Boosting self-control strength may help to prevent the potentially negative anxiety effects.

The role of self-control strength in the development of state anxiety in test situations

Self-control strength may affect state anxiety because emotion regulation is impaired in individuals whose self-control strength has been temporarily depleted. Increases in state anxiety were expected to be larger for participants with depleted compared to nondepleted self-control strength, and trait test anxiety should predict increases in state anxiety more strongly if self-control strength is depleted. In a sample of 76 university students, trait test anxiety was assessed, self-control strength experimentally manipulated, and state anxiety measured before and after the announcement of a test. State anxiety increased after the announcement. Trait test anxiety predicted increases in state anxiety only in students with depleted self-control strength, suggesting that increased self-control strength may be useful for coping with anxiety.

Balancing Control and Coaching in CSO Governance : A Paradox Perspective on Board Behavior

How can governance of civil society organizations be conceptualized more adequately by accounting for the dual and simultaneous requirements of controlling and coaching in board behavior? Empirically, we seem to agree that effective governance of a civil society organization is crucial to its sustained viability. Conceptually, however, we observe a lack of consensus on how to best conceptualize CSO governance. By critically juxtaposing two major theoretical lenses to conceptualize governance, namely agency and stewardship theory, we identify a number of challenges conceptualizing board-management relations that deserve our attention. While agency theory privileges controlling behavior, stewardship theory emphasizes the coaching behavior of boards. The purpose of this paper is to offer a concept of governance that is informed by a paradox perspective advancing a subtler, more adequate conceptualization of board governance that accounts for the often conflicting demands on CSO governance. Drawing on a longitudinal interpretive case study, we exemplify our propositions empirically. The paper concludes with discussing the implications of our argument for CSO governance research and practice.
