Enhancing supply chain innovation and operational agility through knowledge acquisition from the social media: A microfoundational approach

This paper presents an examination of the interlocks between knowledge acquisition from social media (KAfSM), organizational microfoundation structure and design (OMFSaD), supply chain innovation (SCI), and operational agility (OA). These interlocks were tested on data collected from 172 managers/directors/CEOs of 96 firms operating in nine manufacturing industry sectors in Malaysia. Our findings suggest that OMFSaD plays a key role when interlinked with KAfSM. Furthermore, OMFSaD is significantly associated with SCI and OA, and SCI significantly correlates with OA and partially mediates the relationship between OMFSaD and OA. Our study’s outcomes are consistent with our understanding of IT‐enabled organizational capabilities—thus contributing to dynamic capability theory—and suggest that KAfSM helps to revamp processes, routines, and business operations in frequently changing environments. In this paper, we draw implications for research and practice

Global Networks as a Mode of Balance for Exploratory Innovations in a Late Liberalizing Economy

This article suggests that under weak institutional arrangements, adverse economic conditions, and institutional voids in a late liberalizing economy, local firms that are part of the global value chains of multinational enterprises develop international networks as a balancing strategy to engage in exploratory innovations. We argue that local firms do so in order to counter the negative influences of local institutions on exploratory innovations. Using exploratory in-depth qualitative analysis, we study the suppliers of motorcycle parts in Pakistan that are working with leading Japanese and Chinese motorcycle assemblers. The results suggest that in adverse economic situations local institutional factors can sustain only the development of exploitative innovations. As a balancing strategy, motorcycle part suppliers develop international networks with global Tier 1 suppliers, international trade fairs, and international institutions. This strategy helps circumvent the negative influence of home institutional factors on developing exploratory innovations. Our study highlights the importance of global networks as a balancing strategy for creating exploratory innovations by firms in a late liberalizing economy

Efficacy of phenotypic, PCR and MALDI -ToF identification methods for Campylobacter spp.

This study compared phenotypic and genotypic identification methods of Campylobacter spp. against the polymerase chain reaction (PCR) in terms of sensitivity, specificity, positive-predictive value and negative-predictive value. Thermophilic Campylobacter isolates were identified using conventional biochemical tests, specifically hippurate hydrolysis, matrix assisted laser desorption ionization- time of flight (MALDI-ToF) mass spectrometry and PCR with primers unique to C. jejuni and C. coli. MALDI-ToF was shown to be superior to biochemical tests for identification of C. coli but equivalent to biochemical tests for C. jejuni.The National Research Foundation Thuthuka: Researchers in Training Programme Ref.

Cardiac resynchronization therapy in inotrope‐dependent heart failure: a meta‐analysis

Aims: The viability of cardiac resynchronization therapy (CRT) in inotrope‐dependent heart failure (HF) has been a matter of debate. Methods and results: We searched Medline, EMBASE, Scopus, and the Cochrane Library until 31 December 2022. Studies were included if (i) HF patients required inotropic support at CRT implantation; (ii) patients were ≥18 years old; and (iii) they provided a clear definition of ‘inotrope dependence’ or ‘inability to wean’. A meta‐analysis was performed in R (Version 3.5.1). Nineteen studies comprising 386 inotrope‐dependent HF patients who received CRT (mean age 64.4 years, 76.9% male) were included. A large majority survived until discharge at 91.1% [95% confidence interval (CI): 81.2% to 97.6%], 89.3% were weaned off inotropes (95% CI: 77.6% to 97.0%), and mean discharge time post‐CRT was 7.8 days (95% CI: 3.9 to 11.7). After 1 year of follow‐up, 69.7% survived (95% CI: 58.4% to 79.8%). During follow‐up, the mean number of HF hospitalizations was reduced by 1.87 (95% CI: 1.04 to 2.70, P < 0.00001). Post‐CRT mean QRS duration was reduced by 29.0 ms (95% CI: −41.3 to 16.7, P < 0.00001), and mean left ventricular ejection fraction increased by 4.8% (95% CI: 3.1% to 6.6%, P < 0.00001). The mean New York Heart Association (NYHA) class post‐CRT was 2.7 (95% CI: 2.5 to 3.0), with a pronounced reduction of individuals in NYHA IV (risk ratio = 0.27, 95% CI: 0.18 to 0.41, P < 0.00001). On univariate analysis, there was a higher prevalence of males (85.7% vs. 40%), a history of left bundle branch block (71.4% vs. 30%), and more pronounced left ventricular end‐diastolic dilation (274.3 ± 7.2 vs. 225.9 ± 6.1 mL). Conclusions: CRT appears to be a viable option for inotrope‐dependent HF, with some of these patients seeming more likely to respond

Moments of the Hadronic Invariant Mass Spectrum in B --> X_c l nu Decays at Belle

We present a measurement of the hadronic invariant mass squared (M^2_X) spectrum in charmed semileptonic B meson decays B --> X_c l nu based on 140 fb^-1 of Belle data collected near the Y(4S) resonance. We determine the first, the second central and the second non-central moments of this spectrum for lepton energy thresholds ranging between 0.7 and 1.9 GeV. Full correlations between these measurements are evaluated.Comment: published version of the paper (one figure added, minor changes in the text); 16 pages, 3 figures, 10 table

Measurement of the gamma gamma -> pi+ pi- and gamma gamma -> K+ K- processes at energies of 2.4 - 4.1 GeV

We have measured pi+pi- and K+K- production in two-photon collisions using 87.7 /fb of data collected with the Belle detector at the asymmetric energy e+e- collider KEKB. The cross sections are measured to high precision in the two-photon center-of-mass energy (W) range between 2.4 GeV < W < 4.1 GeV and angular region |cos theta^{*}| < 0.6. The cross section ratio sigma(gammagamma->K+K-)/sigma(gammagamma->pi+pi-) is measured to be 0.89 +- 0.04(stat) +- 0.15(syst) in the range of 3.0 GeV < W < 4.1 GeV, where the ratio is energy independent. We observe a sin^{-4} theta^{*} behavior of the cross section in the same W range. Production of chi_{c0} and chi_{c2} mesons is observed in both gammagamma -> pi+pi- and gammagamma -> K+K- modes.Comment: 17 pages, 5 figures, submitted to Phys. Lett.

Search for tau -> e gamma decay at Belle

We have searched for the lepton-flavor-violating decay tau -> e gamma using a data sample of 86.7/fb collected with the Belle detector at the KEKB asymmetric e^+ e^- collider. No evidence for a signal is obtained, and we set an upper limit for the branching fraction Br(tau -> e gamma) < 3.9 x 10^-7 at the 90% C.L.Comment: 11 pages, 10 figures, ReVTeX4, eps
