Virtual Proximity to Promote Expatriate Cultural Adjustment, Innovation, and the Reduction of Stress Levels

Given the dramatic increase in the number of expatriates living and working abroad, there is a need to advance the research into how to make sure these employees achieve success on their assignments. Often, these expatriates assume managerial roles and are intended to be the gatekeepers of information. Typically, this information is necessary for the success of their colleagues, in both their home country and their host country. The expatriate’s role is to facilitate the integration of organizational knowledge from both their home and host countries, as well as key sources in their host country’s local environment. However, historically, there has been an exceptionally high failure rate in expatriate engagements. There are various factors discussed in the literature related to this failure rate including the stress of cultural integration and isolation from family. This often interferes with the expatriate being able to perform of their key responsibilities, which is to innovate. This research will launch pilot studies to investigate the use of social media, and computer mediated communications, to develop virtual proximity, its effects on cultural integration, the maintenance of professional relationships on a global scale, and its effect on the reduction of stress and the innovation process

Supergravity Inflation Free from Harmful Relics

We present a realistic supergravity inflation model which is free from the overproduction of potentially dangerous relics in cosmology, namely moduli and gravitinos which can lead to the inconsistencies with the predictions of baryon asymmetry and nucleosynthesis. The radiative correction turns out to play a crucial role in our analysis which raises the mass of supersymmetry breaking field to intermediate scale. We pay a particular attention to the non-thermal production of gravitinos using the non-minimal Kahler potential we obtained from loop correction. This non-thermal gravitino production however is diminished because of the relatively small scale of inflaton mass and small amplitudes of hidden sector fields.Comment: 10 pages, revtex, 1 eps figure, references added, conclusion section expande

Relaxing the Cosmological Moduli Problem

Typically the moduli fields acquire mass m =C H in the early universe, which shifts the position of the minimum of their effective potential and leads to an excessively large energy density of the oscillating moduli fields at the later stages of the evolution of the universe. This constitutes the cosmological moduli problem, or Polonyi field problem. We show that the cosmological moduli problem can be solved or at least significantly relaxed in the theories in which C >> 1, as well as in some models with C << 1.Comment: 9 pages, 3 Postscript figure

Brighter prospects? Assessing the franchise advantage using census data

This paper uses Census micro data to examine how starting a business as a franchise rather than an independent business affects its survival and growth prospects. We assess factors that influence the decision to become a franchisee and use various empirical approaches to correct for selection bias in our performance analyses. We find that franchised businesses on average exhibit higher survival rates than independent businesses, but importantly, the difference is small compared to claims in the trade press. The effect is also short lived: conditional on surviving a year or two, we no longer find survival (or growth) differences. We then explore two potential sources for this small survival advantage, namely franchisors’ screening process and the benefits arising from the brand and business know-how provided by franchisors. We find evidence that both of the sources contribute to the franchising advantage

The CMS Tracker Readout Front End Driver

The Front End Driver, FED, is a 9U 400mm VME64x card designed for reading out the Compact Muon Solenoid, CMS, silicon tracker signals transmitted by the APV25 analogue pipeline Application Specific Integrated Circuits. The FED receives the signals via 96 optical fibers at a total input rate of 3.4 GB/sec. The signals are digitized and processed by applying algorithms for pedestal and common mode noise subtraction. Algorithms that search for clusters of hits are used to further reduce the input rate. Only the cluster data along with trigger information of the event are transmitted to the CMS data acquisition system using the S-LINK64 protocol at a maximum rate of 400 MB/sec. All data processing algorithms on the FED are executed in large on-board Field Programmable Gate Arrays. Results on the design, performance, testing and quality control of the FED are presented and discussed

Relating PH and Ion Release from Ga2O3-Na 2O-CaO-ZnO-SiO2 Bioactive Glasses

Three glasses were designed for this study, including one Ga-free glass (Control), and two Ga-containing glasses (TGa-1, TGa-2). In the Ga-containing glasses, Ga2O3 is included at the expense of ZnO. This study focuses on the relation between pH and ion concentration present in solution in which these bioactive glasses have been submerged for periods of 1, 7, and 14 days. © 2013 IEEE

Comparison of a SiO2-CaO-ZnO-SrO Glass Polyalkenoate Cement to Commercial Dental Materials: Ion Release, Biocompatibility and Antibacterial Properties

Ion Release and biocompatibility of a CaO-SrO-ZnO-SiO2 (BT 101) based glass polyalkenoate cement (GPC) was compared against commercial GPCs, Fuji IX and Ketac Molar. The radiopacity (R) was similar for each material, 2.0-2.8. Ion release was evaluated on each material over 1, 7, 30 and 90 days. BT 101 release included Ca (23 mg/L), Sr (23 mg/L) Zn (13 mg/L), Si (203 mg/L). Fuji IX release includes Ca (0.7 mg/L), Al (3 mg/L) Si (26 mg/L), Na (60 mg/L) and P (0.5 mg/L) while Ketac Molar release includes Ca (1 mg/L), Al (0.6 mg/L) Si (23 mg/L), Na (76 mg/L) and P (0.7 mg/L). Simulated body fluid trials revealed CaP surface precipitation on BT 101. No evidence of precipitation was found on Fuji IX or Ketac Molar. Cytotoxicity testing found similar cell viability values for each material (~60 %, P = 1.000). Antibacterial testing determined a reduced CFU count with BT 101 (2.5 x 103) when compared to the control bacteria (2.4 x 104), Fuji IX (1.5 x 104) and Ketac Molar (1.2 x 104). © 2013 Springer Science+Business Media New York

Structures for Knowledge Co-creation Between Organisations and the Public

A definitive version of this conference paper is available in the ACM Digital Library http://dx.doi.org/10.1145/2556420.2558854© ACM 2014Social computing technologies are emerging to support innovative new relationships between organisations and the public. Inspired by concepts such as collective intelligence and crowdsourcing, diverse organisations are exploring new ways to increase engagement with the public, collect localised knowledge, or leverage human cognition and creativity. The COP2014 workshop will assimilate the craft understanding and experimentation underpinning innovations in relationships between public and professional realms. We aim to provide an opportunity for discussion and to build understanding of the principles of making these sociotechnical systems work, and discuss possible designs and opportunities that may be valuable and remain underexplored. As a tangible outcome, our main goal will be to co-author a paper discussing our positions on current systems and future visions, for submission to Communications of the ACM. We welcome participation from interested organisations, alongside those conducting research in this area. Topics of interest include: How can systems be designed for participation that is beneficial to individuals and organisations? How do we draw boundaries between ‘official’ and externally-generated knowledge? How can professional activities connect with the just-in-time, emergent nature of amateur interactions?RCUK Horizon Hu
