This paper develops a moderated mediation model in which the interactive effects of food traceability and environmental dynamism on firm performance are mediated by the core capabilities(operating capabilities and marketing capabilities)in food supply chain context, by invoking the indirect view of organizational learning theory. Our hypotheses were tested using hierarchical regression and bootstrapping methods with a sample of 216 food manufacturing firms in China, and a survey-based, two-informant design was used to collect data. The results revealed that operating and marketing capabilities fully mediate the food traceability-performance link. In addition, environmental dynamism positively moderates the food traceability-core capabilities link. Moreover, it is found that operating and marketing capabilities transform the interactive impacts of environmental dynamism and food traceability into firm performance. Our study offers a fine-grained picture of the essential food traceability-performance link by revealing for the first time that there is an interactive impacts of food traceability and environmental dynamism on firm performance via core capabilities.

A recent study published in Cell by the Millay lab reports on an elegant strategy to expand the repertoire of lentiviral(LV)vectors from being the main delivery tool for ex vivo gene therapy to an in vivo applicable viral vector that specifically transduces skeletal muscle.1 This very significant advance may result in novel therapeutics for patients suffering from various skeletal muscle diseases.

A cloud of gas collapsing under gravity will fragment. We present a new theory for this process, in which layers of shocked gas fragment due to their gravitational instability. Our model explains why angular momentum does not inhibit the collapse process. The theory predicts that the fragmentation process produces objects which are significantly smaller than most stars, implying that accretion onto the fragments plays an essential role in determining the initial masses of stars. This prediction is also consistent with the hypothesis that planets can be produced by gravitational collapse.

Tumor metastases present an often difficult to treat therapeutic challenge for cancer patients and their *** recent paper by the Kaplan group(Kaczanowska et al.)exploited the natural capacity of monocytes or a subset of monocytes to migrate to tumor sites and pre-metastatic niches to deliver IL-12 in a novel anticancer approach designed to stimulate local immune responses.1 This raises the possibility to simultaneously fight cancer on at least two critical fronts,(1)elimination of the primary tumor and(2)inhibition of newly developing pre-metastatic lesions.

BACKGROUND:Common bile duct(CBD)stones are known to pass spontaneously in a significant number of patients. This study investigated the rate of spontaneous CBD stones passage in a series of patients presenting with jaundice due to *** patients were managed surgically,allowing CBD intervention to be avoided in the event of spontaneous passage of CBD stones. METHOD:Retrospective analysis of patients presenting with jaundice due to CBD stones,and managed surgically with laparoscopic cholecystectomy and intra-operative cholangiogram with or without CBD exploration. RESULTS:The jaundice settled pre-operatively in 76/108 patients, and in 60/108 the CBD stones had passed spontaneously by the time of *** 60 patients avoided any intervention to their CBD. CONCLUSIONS:CBD stones pass spontaneously in more than half of jaundiced *** management(laparoscopic cholecystectomy and intra-operative cholangiogram,with willingness to perform CBD exploration if positive)allows the avoidance of CBD intervention in these patients.
