Impacts of dynamic managerial capability and international opportunity identification on firm performance
Purpose: This paper aims to investigate the antecedents and outcomes of international opportunity identification (IOI) in export-manufacturing firms. The fundamental question addressed in this research is: How does dynamic managerial capability (DMC) of entrepreneurs contribute to IOI and success of the firms? Design/methodology/approach: The research model was tested through structural equation modeling among the readymade garment manufacturing firms in the least developed country, Bangladesh. A survey was conducted with a random sampling approach and responses were collected from 390 firms. Findings: The salient findings are: DMC has direct and indirect impacts through IOI on financial and non-financial performance; IOI mediates the relationship between managerial social capital and non-financial performance and between managerial cognition and non-financial performance; IOI has a negative relationship with the financial performance of the firms; and scope of accelerated internationalization positively moderates the relationship between IOI and financial performance of firms. Originality/value: This paper notably shows that DMC of export-manufacturing entrepreneurs leads to the identification of the right kind of opportunities, which, in turn, generate better performance. It is advantageous for this type of firm to operate a business in multiple countries
Measuring Brand-Related Content in Social Media: A Socialization Theory Perspective
Purpose- Building on consumer socialization theory, this study examined antecedents and consequences of generating and sharing brand-related content on social media in a restaurant context.
Design/methodology/approach- A scale development process was undertaken to develop the scale for brand-related user-generated content. Then we tested the antecedents and consequences of brand-related user-generated content using 375 responses obtained through a mall-intercept survey. The hypotheses were tested using structural equation modelling with AMOS.
Findings- Study findings revealed that age, time on Facebook, number of Facebook friends, Facebook usage intensity, and need for self-enhancement were key antecedents of both the generation and sharing of brand-related user-generated content. The results also indicated that gender, race, and need for self-affirmation were not significantly related to generating and sharing brand-related user-generated content. Both generating and sharing brand-related user-generated content were positively associated with attitude and intentions toward the restaurants.
Originality/value- This study is the first to develop a brand-related user-generated content scale through a rigorous scale development process. It thus contributes to consumer socialization theory literature in considering social media as a socialization agent. The findings provide valuable insights for both academicians and social media managers and aid in enhancing brand-related user-generated content
Quantum oscillations in the anomalous phase in Sr3Ru2O7
This is the final version. Available from American Physical Society via the DOI in this recordWe report measurements of quantum oscillations detected in the putative nematic phase of Sr3Ru2O7. Improvements in sample purity enabled the resolution of small amplitude de Haas-van Alphen (dHvA) oscillations between two first order metamagnetic transitions delimiting the phase. Two distinct frequencies were observed, whose amplitudes follow the normal Lifshitz-Kosevich profile. Variations of the dHvA frequencies are explained in terms of a chemical potential shift produced by reaching a peak in the density of states, and an anomalous field dependence of the oscillatory amplitude provides information on domains. © 2009 The American Physical Society.Engineering and Physical Sciences Research Council (EPSRC
Quantum oscillations near the metamagnetic transition in Sr3Ru2O7
This is the final version. Available from American Physical Society via the DOI in this recordWe report a detailed investigation of quantum oscillations in Sr 3 Ru2 O7, observed inductively (the de Haas-van Alphen effect) and thermally (the magnetocaloric effect). Working at fields from 3 to 18 T allowed us to straddle the metamagnetic transition region and probe the low- and high-field Fermi liquids. The observed frequencies are strongly field dependent in the vicinity of the metamagnetic transition, and there is evidence for magnetic breakdown. We also present the results of a comprehensive rotation study. The most surprising result concerns the field dependence of the measured quasiparticle masses. Contrary to conclusions previously drawn by some of us as a result of a study performed with a much poorer signal-to-noise ratio, none of the five Fermi-surface branches for which we have good field-dependent data gives evidence for a strong-field dependence of the mass. The implications of these experimental findings are discussed. © 2010 The American Physical Society.Engineering and Physical Sciences Research Council (EPSRC

Evidence of a structural quantum critical point in (CaxSr1-x)3Rh4Sn13 from a lattice dynamics study
Approaching a quantum critical point (QCP) has been an effective route to
stabilize superconductivity. While the role of magnetic QCPs has been
extensively discussed, similar exploration of a structural QCP is scarce due to
the lack of suitable systems with a continuous structural transition that can
be conveniently tuned to 0~K. Using inelastic X-ray scattering, we examine the
phonon spectrum of the nonmagnetic quasi-skutterudite
(CaSr)RhSn, which represents a precious system to
explore the interplay between structural instabilities and superconductivity by
tuning the Ca concentration . We unambiguously detect the softening of
phonon modes around the M point on cooling towards the structural transition.
Intriguingly, at , the soft mode energy squared at the M point
extrapolates to zero at ~K, providing the first compelling
microscopic evidence of a structural QCP in
(CaSr)RhSn. The enhanced phonon density-of-states
at low energy provides the essential ingredient for realizing strong-coupling
superconductivity near the structural QCP
Web-based monitoring tools for Resistive Plate Chambers in the CMS experiment at CERN
The Resistive Plate Chambers (RPC) are used in the CMS experiment at the trigger level and also in the standard offline muon reconstruction. In order to guarantee the quality of the data collected and to monitor online the detector performance, a set of tools has been developed in CMS which is heavily used in the RPC system. The Web-based monitoring (WBM) is a set of java servlets that allows users to check the performance of the hardware during data taking, providing distributions and history plots of all the parameters. The functionalities of the RPC WBM monitoring tools are presented along with studies of the detector performance as a function of growing luminosity and environmental conditions that are tracked over time
Prevalence of inflammatory bowel disease in two districts of Sri Lanka: a hospital based survey
<p>Abstract</p> <p>Background</p> <p>Inflammatory bowel disease (IBD) is being increasingly diagnosed in Asia. However there are few epidemiological data from the region.</p> <p>Methods</p> <p>To determine prevalence and clinical characteristics of IBD, a hospital-based survey was performed in the Colombo and Gampaha districts (combined population 4.5 million) in Sri Lanka. Patients with established ulcerative colitis (UC) and Crohn's disease (CD), who were permanent residents of these adjoining districts, were recruited from hospital registries and out-patient clinics. Clinical information was obtained from medical records and patient interviews.</p> <p>Results</p> <p>There were 295 cases of IBD (UC = 240, CD = 55), of which 34 (UC = 30, CD = 4) were newly diagnosed during the study year. The prevalence rate for UC was 5.3/100,000 (95% CI 5.0-5.6/100,000), and CD was 1.2/100,000 (95% CI 1.0-1.4/100,000). The incidence rates were 0.69/100,000 (95% CI 0.44-0.94/100,000) for UC and 0.09/100,000 (95% CI 0.002-0.18/100,000) for CD. Female:male ratios were 1.5 for UC and 1.0 for CD. Mean age at diagnosis was (males and females) 36.6 and 38.1y for UC and 33.4 and 36.2y for CD. Among UC patients, 51.1% had proctitis and at presentation 58.4% had mild disease. 80% of CD patients had only large bowel involvement. Few patients had undergone surgery.</p> <p>Conclusions</p> <p>The prevalence of IBD in this population was low compared to Western populations, but similar to some in Asia. There was a female preponderance for UC. UC was mainly mild, distal or left-sided, while CD mainly involved the large bowel.</p
Mechanisms controlling anaemia in Trypanosoma congolense infected mice.
Trypanosoma congolense are extracellular protozoan parasites of the blood stream of artiodactyls and are one of the main constraints on cattle production in Africa. In cattle, anaemia is the key feature of disease and persists after parasitaemia has declined to low or undetectable levels, but treatment to clear the parasites usually resolves the anaemia. The progress of anaemia after Trypanosoma congolense infection was followed in three mouse strains. Anaemia developed rapidly in all three strains until the peak of the first wave of parasitaemia. This was followed by a second phase, characterized by slower progress to severe anaemia in C57BL/6, by slow recovery in surviving A/J and a rapid recovery in BALB/c. There was no association between parasitaemia and severity of anaemia. Furthermore, functional T lymphocytes are not required for the induction of anaemia, since suppression of T cell activity with Cyclosporin A had neither an effect on the course of infection nor on anaemia. Expression of genes involved in erythropoiesis and iron metabolism was followed in spleen, liver and kidney tissues in the three strains of mice using microarrays. There was no evidence for a response to erythropoietin, consistent with anaemia of chronic disease, which is erythropoietin insensitive. However, the expression of transcription factors and genes involved in erythropoiesis and haemolysis did correlate with the expression of the inflammatory cytokines Il6 and Ifng. The innate immune response appears to be the major contributor to the inflammation associated with anaemia since suppression of T cells with CsA had no observable effect. Several transcription factors regulating haematopoiesis, Tal1, Gata1, Zfpm1 and Klf1 were expressed at consistently lower levels in C57BL/6 mice suggesting that these mice have a lower haematopoietic capacity and therefore less ability to recover from haemolysis induced anaemia after infection
Radiation background with the CMS RPCs at the LHC
The Resistive Plate Chambers (RPCs) are employed in the CMS Experiment at the LHC as dedicated trigger system both in the barrel and in the endcap. This article presents results of the radiation background measurements performed with the 2011 and 2012 proton-proton collision data collected by CMS. Emphasis is given to the measurements of the background distribution inside the RPCs. The expected background rates during the future running of the LHC are estimated both from extrapolated measurements and from simulation
2017 Kidney Disease: Improving Global Outcomes (KDIGO) Chronic Kidney Disease–Mineral and Bone Disorder (CKD-MBD) Guideline Update Implementation: Asia Summit Conference Report
Improving Global Outcomes (KDIGO) Clinical Practice Guideline on Chronic Kidney Disease–Mineral and Bone Disorder (CKD–MBD) 2009 provided recommendations on the detection, evaluation, and treatment of CKD-MBD in patients CKD who are and are not undergoing dialysis. Because of the accumulation of evidence since this initial publication, the CKD-MBD Guideline underwent a selective update in 2017. In April 2018, KDIGO convened a CKD-MBD Guideline Implementation Summit in Japan with the key objective to discuss various barriers to the uptake and implementation of the CKD-MBD Guideline in 8 Asian countries/regions. These countries/regions were comparable according to their high-to-middle economic ranking assigned by the World Bank. The discussion took into account the availability of CKD-MBD medication therapies and government health policies that may influence reimbursement and practice patterns in the region. Most importantly, Summit participants developed a framework of multifaceted strategies aimed at overcoming barriers to guideline implementation. The Summit attendees suggested a shared decision-making approach between clinicians and patients in CKD-MBD management, as well as individualized care based on the treatment risk-benefit ratio. The Summit participants also discussed how KDIGO, as a guideline development organization, may work in partnership with local and national nephrology societies to provide education and facilitate implementation of the guideline by clinicians. The conclusions drawn from this Summit in Asia may serve as an important guide for other regions to follow
