The projection and measurement of cyberpower

Cyberspace and cyberpower are terms that are increasingly used in common parlance, but are notoriously difficult to define and measure. This article builds on previous work defining the properties of cyberspace in terms of vertical layers, which when combined with a representation of distance presents a three-dimensional model. The unique attributes of cyberspace can be harnessed for power projection, the aim of which is ultimately to alter the behaviour of individuals. Although cyberspace has yet to be used as a medium to demonstrate conventional hard power of coercion and threats supported by physical force, it does present a suitable medium for the projection of soft power of attraction and imitation. These are defined within the context of the online environment and by drawing on the techniques used to optimise Web-based commerce, potential methods of implementing and measuring the success of a campaign of cyberpower projection are proposed

Coworking Spaces: Empowerment for Entrepreneurship and Innovation in the Digital and Sharing Economy

Freelancers, entrepreneurs, new ventures, but also incumbent firms increasingly use coworking spaces (CWS). The alignment of work-space and social space can facilitate organizational empowerment supporting individual work satisfaction. Our mixed-methods study of 328 respondents from CWS in 26 cities in the USA, Germany, and China identifies configurations of institutional patterns on work satisfaction associated with a sense of community, autonomy, participation, linkage multiplicity and mutual knowledge creation. High work satisfaction can occur in three different configurations related to a) agility housing, b) knowledge housing, and c) social housing. Our findings contribute to how incumbent firms and CWS can influence work satisfaction and empower towards innovation and entrepreneurial performance

The uninsured and Medicaid Oregon tobacco user experience in a real world, phone based cessation programme

Objective: To describe the experience of uninsured and Medicaid Oregon tobacco users who registered in Free & Clear (F&C), a telephone based cessation programme including five scheduled outbound calls. Design and setting: Using a retrospective cohort design, 1334 (423 uninsured, 806 Medicaid, and 105 commercially insured) Oregon tobacco users who registered in F&C between 18 November 1998 and 28 February 2000 were identified and followed for 12 months post-registration; 648 (48.6%) were successfully contacted at 12 months. Information was collected from the F&C database. Unconditional logistic regression, adjusted for race and education, was used. Results: The seven day quit rate at 12 months, assuming non-respondents were smokers, was 14.8% (95% confidence interval (CI) 13.0 to 16.9). This rate was significantly higher among commercially insured participants (v Medicaid but not uninsured) and among participants who completed ⩾ 5 calls (v < 5 calls). The quit rate for those contacted at 12 months was 30.6% (95% CI 27.0% to 34.3%) and varied, however not significantly, by insurance and number of calls. After adjustment, respondents who completed ⩾ 5 calls were 60% more likely to quit tobacco (odds ratio (OR) 1.6, 95% CI 0.9 to 3.1), and uninsured respondents who completed ⩾ 5 calls were 70% more likely to quit tobacco (OR 1.7, 95% CI 0.9 to 3.5), relative to those who completed < 5 calls, but the difference was not significant. Conclusions: The quit rates are similar to those reported in efficacy trials. The observed variation in quitting tobacco for respondents by number of calls completed and by insurance merits further investigation concentrating on increasing compliance with the call schedule, particularly for the uninsured

N-terminal Dbl domain of the RhoGEF, Kalirin.

Guanine nucleotide exchange factors (GEF) promote the release of GDP from GTPases, thus allowing the free GTPase molecule to bind the more abundant GTP molecule. In the GTP-bound state, the GTPase elicits signal transduction by acting on its effector proteins. Spontaneous release of GDP is a slow process and the catalysis of the GDP release by a GEF is generally a prerequisite for efficient signaling (Vetter and Wittinghofer 2001). The structurally related GEFs form subfamilies that regulate a specific family of GTPase proteins. GEFs that activate Rho GTPases have been implicated in cancer and mental retardation. RhoGEFs are a relatively large family, and many of the *69 human RhoGEFs were discovered based on their oncogenic activation in cancer and cancer models. The catalytic components of RhoGEFs are referred to as Dbl homology domains, after the screen that identified the protein Dbl encoded by the diffuse B-cell lymphoma (dbl) oncogene (Eva and Aaronson 1985). Thus the RhoGEF family is a potential target for treating tumors and cancer
