中职机电专业教学改革探讨

目前科技的飞速发展对中职毕业生提出了越来越高的要求,而学生的各方面素质却相对较差,学习积极性、主动性不高。以能力为本位进行中职机电专业课程体系改革是提高学生机电专业理论水平和动手操作能力的必然选择。根据机电专业岗位群的工作过程,分析了岗位能力要求,从而确定了本专业培养目标,设计了基于职业能力和项目化的学习情景,以求改革原有的课程设计理念,实现专业课程教育与工作任务与综合职业能力培养要求相统一的课程体系建设目标。     

突发事件网络舆情研究进展与趋势分析

近年来,互联网的发展和突发事件的频发导致突发事件网络舆情成为学者们关注的热点之一,但相关研究缺乏对突发事件网络舆情研究文献的量化和可视化分析。文章选取2009-2018年CNKI中的223篇以突发事件网络舆情为主题的CSSCI来源期刊和北大核心期刊文献为样本,利用Citespace对文献作者、研究机构、关键词等绘制知识图谱,对研究热点、研究演化路径和未来研究趋势进行分析。研究表明：基于突发事件网络舆情主体、表现形式、预警和应对策略的研究是当前的研究热点,未来研究将会朝着高校突发事件网络舆情、突发事件非理性网络舆论、突发事件网络舆情演化、突发事件网络舆情治理研究等方面展开。     

Operational Risk in Financial Services: A Review and New Research Opportunities

We present a framework to describe and analyze operational risk in financial services from an operations management perspective, focusing in particular on process design, process management, and human behavior aspects. The financial services industry differs from other service industries in ways that affect the nature of the operational risks it is subject to. In recent decades, many books and papers have focused on operational risk in financial services; however, this literature has focused mainly on the conceptual and statistical aspects of operational risk management and not on its operational aspects. Operational risk in financial services has not received much attention from the operations management community. The framework presented here is based on the premise that operational risk in financial services can reap significant benefits from research done in the theory and practice of operations management in manufacturing industries as well as in other services industries. The objective of this study is to propose particular challenges and questions raised in the practice of operational risk management that may stimulate future research in this particular area of operations management.     

Optimal Dynamic Order Scheduling under Capacity Constraints Given Demand‐Forecast Evolution

We consider a manufacturer without any frozen periods in production schedules so that it can dynamically update the schedules as the demand forecast evolves over time until the realization of actual demand. The manufacturer has a fixed production capacity in each production period, which impacts the time to start production as well as the production schedules. We develop a dynamic optimization model to analyze the optimal production schedules under capacity constraint and demand‐forecast updating. To model the evolution of demand forecasts, we use both additive and multiplicative versions of the martingale model of forecast evolution. We first derive expressions for the optimal base stock levels for a single‐product model. We find that manufacturers located near their market bases can realize most of their potential profits (i.e., profit made when the capacity is unlimited) by building a very limited amount of capacity. For moderate demand uncertainty, we also show that it is almost impossible for manufacturers to compensate for the increase in supply–demand mismatches resulting from long delivery lead times by increasing capacity, making lead‐time reduction a better alternative than capacity expansion. We then extend the model to a multi‐product case and derive expressions for the optimal production quantities for each product given a shared capacity constraint. Using a two‐product model, we show that the manufacturer should utilize its capacity more in earlier periods when the demand for both products is more positively correlated.     

应当强调办案的社会效果

法律的概括性、抽象性、发展性等特点决定了有必要强调办案的社会效果。强调办案的社会效果有利于制约司法自由裁量权,是新时期司法工作的必然要求。     

探析我国突发公共卫生危机治理的路向选择

文章就当前我国突发公共卫生危机应对只处于“管理”而非“治理”的现状,提出我国需要建设由政府部门、非政府组织、私营部门、公民个人和家庭及国际组织等全主体力量的参与,形成高度组织化的突发公共卫生危机治理体系,使之成为全主体、全危险要素、全过程应对突发公共卫生危机的长期合作网络和制度平台,即着眼全球视野的治理网络,凝聚全国组织治理公共卫生危机的整体合力;着力全主体应急平台建设,整合全部资源畅通公共卫生危机的信息机制;着手全方位应急预案体系,操演全新流程强化公共卫生危机的响应计划;着重全国民疾病防控体系,强化全员监督提高公共卫生危机的应对能力;着实全社会应急知识宣教,推动全民学习锻造公共卫生危机的组织实力。     

百合、枸杞对运动能力影响机制的探讨

从化学成分、生物活性、以及对运动能力的影响等多方丽对近年来百合与枸杞的研究和应用进行了论述,发现百合与枸杞同作为补益类植物资源,具有较高的药用价值和保健功能,在运动方面也有很好的抗疲劳、耐缺氧和抗氧化作用,能有效地延缓运动性疲劳,改善运动能力,在运动领域内具有广阔的应用前景。     

治理能力与社会机会——基于世界治理指标的实证研究

社会机会能够提高人类的发展水平,促进社会成员个人发展质量的提高.社会成员对社会机会的广泛共享是经济社会协调发展的基本取向,也是政府治理行为追求的重要目标之一.通过对各国政府治理能力和社会机会水平之间关系的实证研究发现,治理能力的提升有助于社会机会的扩大,能够促进全社会成员共享经济和社会发展的成果.     

宁夏人口与生态环境面临的问题及对策

宁夏是少数民族地区,较为宽松的生育政策。导致人口快速增殖。由于宁夏所处的地理位置和历史遗留的生态债务使得境内生态环境十分脆弱。尤其是人口过度增殖已超出了刚性土地资源的有效容纳力。这不仅给环境造成了巨大压力,也进一步加剧了生态环境的恶化。本文通过大量统计数据和实地调研。分析了近年来宁夏人口与生态环境之间存在的亟待解决的矛盾和问题。分析表明,当前宁夏尤其是宁南山区人口数量与人口素质、人口数量与生态存量和生态消费之间表现出了明显的此长彼消的关系。在分析的基础上．提出了人口与生态环境建设方面的政策建议。
