Academics and practitioners agree that excellence in supply management results in better quality, customer service, and channel performance. Yet, most of these studies are either conceptual in nature or actual case studies. The primary objective Ž . of this research is to test the impact of a supply management orientation SMO on the suppliers’ operational performance Ž . and buyers’ competitive...

This paper shows that the competitive learning rule found in Learning Vector Quantization (LVQ) serves as a promising function approximator to enable reinforcement learning methods to cope with a large decision search space, defined in terms of different classes of input patterns, like those found in the game of Go. In particular, this paper describes S[arsa]LVQ, a novel reinforcement learning ...

Introduction: Posttraumatic stress disorder is a severe anxiety disorder caused by exposure to traumatic events. The aim of this study was to induce PTSD in rats and examine the effect of WIN55-212-2, a cannabinoid receptor agonist, on anxiety. Methods: SPS&S model was used to induce PTSD in 56 male Wistar rats. Rats were restrained for 2 h, immediately followed by forced swimming for 20 mi...

The study of the competitive outcome associated with two consumers of the same resource, algae, is investigated under asymmetric intraguild interactions and carrying capacities that are a function of resource (algae) availability at any time. The mathematical model is motivated by our understanding of the interactions of genus Protoperidinium (toxin producing) and Heterocapsa (non-toxic produci...

Felix, a Gay Latino man, presented with anxiety and panic attacks, which were addressed as symptoms of minority stress and self-stigma. The client’s panic attacks were eliminated and anxiety was reduced by cognitive-behavioral therapy that targeted his concealment of his sexual orientation and that increased his active coping. By facing his fears of the negative impact of self-disclosure of his...

objectives this study compared the effects of peer education and an orientation tour on anxiety in patients who were candidates for coronary artery angiography. patients and methods this single blind quasi-experimental study was conducted in 2014. a total of 177 patients who were candidates for coronary artery angiography were divided into three groups: a peer education group, an orientation to...

Recent evidence suggests an involvement of the endocannabinoid system in the regulation of emotional behaviour and ethanol intake. Here we investigated age-specific acute behavioural effects of the cannabinoid receptor agonist WIN 55,212-2 (WIN) on anxiety-related behaviour and voluntary ethanol consumption in rats. Animals were treated with WIN (1.2 mg/kg)/vehicle at puberty onset on postnatal...

Introduction: Previous studies have shown that cannabinoidergic system is involved in anxiety. However, there are controversial reports in the experimental studies. The aim of this study is to evaluate the effect of pharmacological stimulation or blocking of CB1 receptors and inhibition of endocannabinoid degradation in anxiety like behavior in elevated plus-maze (EPM) test in rat. The EPM is o...
