简介:电话中心在过去的十年期间变得世界范围。调用中心管理器考虑的最重要的方面之一是它的操作符的优化,它暗示盖住高度可变的需求并且发现一个有效方法把人分到某些移动以便完成理想的服务水平和放弃率。另一挑战正在决定安装为特定的电话中心是哪个系统适当的。我们应该有一个单个技巧的电话中心或多技巧电话中心吗?如果我们确实有后者,我们应该欺骗多少多技巧代理人职员?在这案例研究,我们产生并且分析分离事件的系统模拟优化模型在实际配置下面并且在跨training的不同层次下面测试一个真实世界的调用中心的行为。模型结果帮助打电话给中心经理由:1)决定操作员的最佳的号码需要让不同职员配置以便为服务水平和放弃完成目标;2)在电话中心关于在关键大小之间的交易提供信息;并且3)关于需要并且使用了每工作时间估计要求完成性能的四小时的移动的号码的操作符的号码提供有用信息指向。我们从这案例研究的试验性的调查结果建议一个双性人技巧电话中心在与一个完整技巧或单个技巧的电话中心相比的长期间经济地更好。这案例研究由为操作管理社区提供另外的经理的卓见扩充知识的电话中心身体。
简介:AbstractBackground:Several recent genome-wide association studies suggested insomnia and anemia may share some common genetic components. We thus examined whether adults with anemia had higher odds of having insomnia relative to those without anemia in a cross-sectional study and a meta-analysis.Methods:Included in this cross-sectional study were 12,614 Chinese adults who participated in an ongoing cohort, the Kailuan Study. Anemia was defined as hemoglobin levels below 12.0 g/dL in women and 13.0 g/dL in men. Insomnia was assessed using the Chinese version of the Athens Insomnia Scale (AIS). A total AIS score ≥6 was considered insomnia. The association between anemia and insomnia was assessed using a logistic regression model, adjusting for potential confounders such as age, sex, chronic disease status, and plasma C-reactive protein concentrations. A meta-analysis was conducted using the fixed effects model to pool results from our study and three previously published cross-sectional studies on this topic in adult populations.Results:Individuals with anemia had greater odds of having insomnia (adjusted odds ratio [OR]: 1.32; 95% confidence interval [CI]: 1.03-1.70) compared with individuals without anemia. A significant association persisted after we excluded individuals with chronic inflammation, as suggested by C-reactive protein levels >1 mg/L (adjusted OR: 1.68; 95% CI: 1.22-2.32). The meta-analysis results, including 22,134 participants, also identified a positive association between anemia and insomnia (pooled OR: 1.39; 95% CI: 1.22-1.57).Conclusions:The presence of anemia was significantly associated with a higher likelihood of having insomnia in adults. Due to the nature of the cross-sectional study design, results should be interpreted with caution.

简介:AbstractThe homeostasis of the gut-brain axis has been shown to exert several effects on physiological and psychological health. The gut hormones released by enteroendocrine cells scattered throughout the gastrointestinal tract are important signaling molecules within the gut-brain axis. The interaction between gut microbiota and gut hormones has been greatly appreciated in gut-brain cross-talk. The microbiota plays an essential role in modulating many gut-brain axis-related diseases, ranging from gastrointestinal disorders to psychiatric diseases. Similarly, gut hormones also play pleiotropic and important roles in maintaining health, and are key signals involved in gut-brain axis. More importantly, gut microbiota can affect the release and functions of gut hormones. This review highlights the role of gut microbiota in the gut-brain axis and focuses on how microbiota-related gut hormones modulate various physiological functions. Future studies could target the microbiota-hormones-gut brain axis to develop novel therapeutics for different psychiatric and gastrointestinal disorders, such as obesity, anxiety, and depression.
