Bayesian Model comparison of Higgs couplings

We investigate the possibility of contributions from physics beyond the Standard Model (SM) to the Higgs couplings, in the light of the LHC data. The work is performed within an interim framework where the magnitude of the Higgs production and decay rates are rescaled though Higgs coupling scale factors. We perform Bayesian parameter inference on these scale factors, concluding that there is good compatibility with the SM. Furthermore, we carry out Bayesian model comparison on all models where any combination of scale factors can differ from their SM values and find that typically models with fewer free couplings are strongly favoured. We consider the evidence that each coupling individually equals the SM value, making the minimal assumptions on the other couplings. Finally, we make a comparison of the SM against a single "not-SM" model, and find that there is moderate to strong evidence for the SM.Comment: 24 pages, 4 figure

Capacity building for transnationalisation of higher education

Purpose – Transnationalism and transnational concept are extensively researched in many social science areas; however, transnational management and transnational marketing is relatively a less explored research domain. Also, knowledge management for transnational education (TNE) marketing is not well-researched. Capacity building is an established research-stream, with a key focus on socio-economic and ecological development; however, prior research on capacity building from the context of TNE’s knowledge management and marketing is scarce. The purpose of this study is to analyse TNE marketing mix, to understand the influence of transnational stakeholders’ causal scope(s) on knowledge management in TNE to uphold their transnatioalisation processes through capacity building in TNEs’ marketing management. Design/methodology/approach – An inductive constructivist method is followed. Findings – Organisational learning from the context of transnational market and socio-economic competitive factors, based on analysing the transnational stakeholders’ causal scope(s) is imperative for proactive knowledge management capacity in TNE marketing. Following the analysis of transnational stakeholders’ causal scope(s) to learn about the cause and consequence of the transnational stakeholders’ relationships and interactions, an initial conceptual framework of knowledge management for TNE marketing is proposed. Practical insights from different TNE markets are developed in support of this novel knowledge management capacity building framework of TNE, and its generalisation perspectives and future research areas are discussed. Practical implications – These insights will be useful for TNE administrators to better align their knowledge management perspectives and propositions with their transnational stakeholders to underpin TNE marketing. Academics will be able to use these insights as a basis for future research. Originality/value – This study proposes a novel conceptual stakeholder-centred capacity building framework for TNE’s knowledge management to uphold TNE marketing and supports the framework, based on practical insights from three different transnational markets

Development of Landslide Warning System

Landslides cause approximately 25 to 50 deaths and US$1 - 2 billion worth of damage in the United States annually. They can be triggered by humans or by nature. It has been widely recognized that rainfall is one of the major causes of slope instability and failure. Slope remediation and stabilization efforts can be costly. An early warning system is a suitable alternative and can save human lives. In this project, an early warning system was developed for a 40-foot-high cut slope on the island of Hawaii. To achieve the objective, subsurface investigations were performed and undisturbed samples were collected. For the purpose of unsaturated soil testing, new testing apparatuses were developed by modifying the conventional oedometer and direct shear cells. The unsaturated soil was characterized using two separate approaches and, later, the results were discussed and compared. The slope site was instrumented for the measurement of suction, water content, displacement, and precipitation. The collected climatic data along with the calibrated hydraulic parameters were used to build an infiltration-evapotranspiration numerical model. The model estimations were compared with the field measurements and showed good agreement. The verified model was used to determine the pore-water pressure distribution during and after a 500-years return storm. Later, the pore-water pressure distribution was transferred to a slope stability software and used to study the slope stability during and after the storm. Based on a 2D slope stability analysis, the slope can survive the 500-year storm with a factor of safety of 1.20. Instrument threshold values were established for water content sensors and tensiometers using a traffic-light-based trigger criterion

Economy and Ecology: Encounters and Interweaving

In this editorial text, we point to the importance and development of disciplines that closely link economic sciences with ecology. Drawing on the most important literature in these fields, we have highlighted the trends that are popular today in both fields (double eco features)

Effective Bounds for the Andrews spt-function

In this paper, we establish an asymptotic formula with an effective bound on the error term for the Andrews smallest parts function $\mathrm{spt}(n)$. We use this formula to prove recent conjectures of Chen concerning inequalities which involve the partition function $p(n)$ and $\mathrm{spt}(n)$. Further, we strengthen one of the conjectures, and prove that for every $\epsilon>0$ there is an effectively computable constant $N(\epsilon) > 0$ such that for all $n\geq N(\epsilon)$, we have \begin{equation*} \frac{\sqrt{6}}{\pi}\sqrt{n}\,p(n)<\mathrm{spt}(n)<\left(\frac{\sqrt{6}}{\pi}+\epsilon\right) \sqrt{n}\,p(n). \end{equation*} Due to the conditional convergence of the Rademacher-type formula for $\mathrm{spt}(n)$, we must employ methods which are completely different from those used by Lehmer to give effective error bounds for $p(n)$. Instead, our approach relies on the fact that $p(n)$ and $\mathrm{spt}(n)$ can be expressed as traces of singular moduli.Comment: Changed the title. Added more details and simplified some arguments in Section

Signals for Noncommutative QED at Future e+e−e^+e^- Colliders

The signatures for noncommutative QED at $e^+e^-$ colliders with center of mass energies in the range of 0.5-5 TeV are examined. For integrated luminosities of 0.5-1 ab$^{-1}$ or more, sensitivities to the associated mass scales greater than $\sqrt s$ are possible.Comment: LaTex, 6 pages, 6 figs; to appear in the Proceedings of the Fourth International Workshop on $e^-e^-$ Interactions at TeV Energies, UC Santa Cruz, 7-9 Dec 200
