Career development tips for today's nursing academic: bibliometrics, altmetrics and social media

© 2016 John Wiley & Sons Ltd Aims: A discussion of bibliometrics, altmetrics and social media for the contemporary nursing scholar and academic researcher. Background: Today's nursing academic faces myriad challenges in balancing their daily life and, in recent years, academic survival has been increasingly challenged by the various research assessment exercises that evaluate the performance of knowledge institutions. As such, it is essential that today's nursing academic keep up to date with the core competencies needed for survival in a modern research career, particularly the intersecting triad of bibliometrics, altmetrics and social media. Design: Discussion paper. Data sources: Published literature and relevant websites. Implications for nursing: The rise of social media and altmetrics has important implications for contemporary nursing scholars who publish their research. Some fundamental questions when choosing a journal might be ‘does it have a Twitter and/or Facebook site, or a blog (or all three)’; and ‘does it have any other presence on social media, such as LinkedIn, Wikipedia, YouTube, ResearchGate and so on?’ Another consequence of embracing social media is that individual academics should also develop their own strategies for promoting and disseminating their work as widely as possible. Conclusion: The rising importance of social media and altmetrics can no longer be ignored, and today's nursing academic now has another facet to consider in their scholarly activities. Despite the changing nature of research dissemination, however, it is still important to recognize the undoubted value of established knowledge dissemination routes (that being the peer-reviewed publication)

Study of a Dynamic Cooperative Trading Queue Routing Control Scheme for Freeways and Facilities with Parallel Queues

This article explores the coalitional stability of a new cooperative control policy for freeways and parallel queuing facilities with multiple servers. Based on predicted future delays per queue or lane, a VOT-heterogeneous population of agents can agree to switch lanes or queues and transfer payments to each other in order to minimize the total cost of the incoming platoon. The strategic interaction is captured by an n-level Stackelberg model with coalitions, while the cooperative structure is formulated as a partition function game (PFG). The stability concept explored is the strong-core for PFGs which we found appropiate given the nature of the problem. This concept ensures that the efficient allocation is individually rational and coalitionally stable. We analyze this control mechanism for two settings: a static vertical queue and a dynamic horizontal queue. For the former, we first characterize the properties of the underlying cooperative game. Our simulation results suggest that the setting is always strong-core stable. For the latter, we propose a new relaxation program for the strong-core concept. Our simulation results on a freeway bottleneck with constant outflow using Newell's car-following model show the imputations to be generally strong-core stable and the coalitional instabilities to remain small with regard to users' costs.Comment: 3 figures.

Cuba's Economic 'Reforms': Waiting for Fidel on the Eve of the Twenty-First Century.

In this paper we provide a brief summary and evaluation of the main economic changes or 'reforms' undertaken by the Cuban government during the 1990's. The thrust of our argument is that the regime does not seem to be interested in reforms that lead to a transition to a market economy or even in the more limited goal of introducing widespread market mechanisms subservient to the needs of the communist party as in China. Instead, their policies seem directed at generating mechanisms for the appropriation of foreign exchange by members of the nomenclature while keeping most citizens deprived of independent access to wealth creation activities. We develop our argument by looking separately at 'reforms' in two type of markets: those in which transactions are self-enforcing and those which depend on the contract enforcement mechanisms or services usually associated with market augmenting government to enforce transactions.Cuba, Reforms, Transition, Markets, Self-enforcing Transactions, Market Augmenting Government

Crossed products and entropy of automorphisms

Let A be an exact C^*-algebra, let G be a locally compact group, and let (A,G,\alpha) be a C*-dynamical system. Each automorphism \alpha_g induces a spatial automorphism Ad_{\lamba_g} on the reduced crossed product A\times_\alpha G. In this paper we examine the question, first raised by E. Stormer, of when the topological entropies of \alpha_g and Ad_{\alpha_g} coincide. This had been answered by N. Brown for the particular case of discrete abelian groups. Using different methods, we extend his result to a wider class of groups called locally [FIA]^-. This class includes all abelian groups, both discrete and continuous, as well as all compact groups.Comment: A few corrections suggested by the referee. To appear in Journal of Functional Analysi

Vanishing of second cohomology for tensor products of typeII1_1 von Neumann algebras

We show that the second cohomology group $H^2(M\overline\otimes N, M\overline\otimes N)$ is always zero for arbitrary type II$_1$ von Neumann algebras $M$ and $N$.Comment: 13 page

Echelle Spectroscopy of gamma-ray binary 1FGL J1018.6-5856

We observed the Fermi-discovered gamma-ray binary 1FGL J1018.6-5856 at 20 epochs over 50 days using the CHIRON spectrograph, obtaining spectra at R~25,000 covering 4090-8908A. The average spectrum confirms an O6 V((f)) spectral type and extinction E(B-V) = 1.35+/-0.04. Variable absorption line equivalent widths suggest substantial contamination by wind line features. The limited S/N ratio hindered accurate continuum definition and prevented measurement of a high quality radial velocity curve. Nevertheless, the best data indicate a radial velocity amplitude <40 km/s for the He II lines and substantially lower for H I. We argue that this indicates a most likely compact object mass <2.2Msun. While black hole solutions are not excluded, a neutron star source of the gamma-ray emission seems preferred.Comment: 5 figures. To appear in the Astrophysical Journa
