结构性变动对劳动生产率的影响：模型与实证

结构性改革的重点是通过经济结构变动、调整和优化,在市场配置的基础上充分促进劳动力流动,让低效率部门劳动力充分向高效率部门流动,从而激发劳动者的生产积极性,促进劳动生产率增长。因此,理论上两部门结构性效率差异模型分析了高效率部门和低效率部门之间劳动力流动对于激发劳动者积极性、提升劳动生产率的影响。在此基础上,使用1978-2017年城乡结构、产业结构、所有制结构、区域结构等年度时间序列数据,分析各自对于劳动生产率变动的影响。计量结果表明,在各种结构性变动因素影响劳动生产率的作用中,按照大小顺序依次是城市化、区域经济适度均衡并允许有条件区域加快发展、市场化和产业结构优化。因此,要通过有效促进城镇化、发达区域经济适度领先发展、市场化和产业结构高度化,来提高劳动生产率。     

Postmortem Computed Tomography and Magnetic Resonance Imaging of Gunshot Wounds to the Neck

Postmortem magnetic resonance imaging (MRI) is rarely used for the radiologic assessment of gunshot injuries, although it has clear advantages over postmortem computed tomography (CT) with regard to the imaging of soft tissue injuries. Another benefit in using MRI is that lodged projectiles composed of nonferromagnetic material such as lead present only marginal metal artifacts compared with severe artifacts on CT. This case report presents CT and MRI findings in a case with two gunshot wounds to the neck: a perforating wound and a nonperforating wound with a lead bullet lodged in the cervical spine. The decedent underwent CT and MRI before the scheduled autopsy. A ring of radiopaque material under the dermis in the fatty tissue was identified at both entrance wounds on CT, which was indicative of contact shots. The perforating gunshot was clearly indicated on CT by bullet fragments along the wound channel through the perforated 6th cervical vertebra and the fractured cricoid cartilage at the exit wound. The second trajectory, however, was only assumed based on the presence of gunshot residues at the entrance wound and the position of the lodged bullet. The radiologic assessment was severely impeded by the metal artifacts on CT. Barely noticeable metal artifacts on MRI allowed for clear visualization of the soft tissue injuries and the ruptured medulla oblongata. Only MRI clarified the soft tissue injuries of the brainstem noninvasively, which could provide specific and graphic information on the rapidity of death and the incapacitation of the victim.     

a feminist menagerie

This paper appraises the role of critical-feminist figurations within the environmental humanities, focusing on the capacity of figures to produce situated environmental knowledges and pose site-specific ethical obligations. We turn to four environments—the home, the skies, the seas and the microscopic—to examine the work that various figures do in these contexts. We elucidate how diverse figures—ranging from companion animals to birds, undersea creatures and bugs—reflect productive traffic between longstanding concerns in feminist theory and the environmental humanities, and generate new insights related to situated knowledges, feminist care-ethics and the politics of everyday sensory encounters. We also argue, however, that certain figures have tested the limits of theoretical approaches which have emerged as the product of dialogue between feminist theory and environmental studies. In particular, we explore how particular figures have complicated ethical questions of how to intervene in broad environmental threats borne of anthropogenic activities, and of who or what to include in relational ethical frameworks.     

新时代工人阶级地位和作用现状及发展趋势

本文以习近平新时代中国特色社会主义思想为根本指导,以习近平总书记关于工人阶级重要论述作为认识问题、分析问题和解决问题的基本立场、观点和方法,立足新时代中国工人阶级地位和作用的发展变化,对新时代工人阶级地位和作用的特点、存在的问题进行了深入研究,分析其发展趋势,并提出了相关对策建议。     

农民工过度劳动的影响因素分析

本文基于2012年和2014年中国家庭追踪调查数据(CFPS),建立了农民工过度劳动选择方程、过度劳动时间方程和持续过度劳动方程,并分析农民工过度劳动的影响因素。研究结果表明,工资水平低是导致农民工过度劳动现象严重的重要原因;受教育水平的提高有助于降低农民工过度劳动和持续过度劳动的概率;劳动合同的签订有助于降低农民工过度劳动的概率、减轻农民工过度劳动程度和降低农民工过度劳动的持续性;不同职业类型的农民工过度劳动程度存在明显差异,在农民工就业拥挤的职业中过度劳动现象更加严重。因而,政府部门在保证农民工基本收入的条件下,提升农民工群体的受教育水平和技能水平,增加其就业稳定性,消除职业隔离,将有助于缓解农民工群体的过度劳动。     

东北老工业基地全面振兴中的劳模文化价值探析

东北老工业基地的劳模文化集中表现为以"爱岗敬业、争创一流、艰苦奋斗、勇于创新、淡泊名利、甘于奉献"为本质内涵的劳模精神,是东北老工业基地全面振兴的重要精神资源,应充分发挥其在全面振兴东北老工业基地中的重要价值。使劳模文化融入到政府的建设中,企业的实践中,人才的培养中。把劳模文化融入培育和践行社会主义核心价值观的全过程。     

女性就业歧视公益诉讼制度法律机理研究

现行法律对女性就业歧视司法救济的规定不足,难以解决女性劳动者力量弱小、举证难、现有诉讼制度不足等问题。为进一步保障我国女性平等就业,需要构建女性就业歧视公益诉讼制度,从正当性、必要性、可行性分析其的法理基础。并对该制度的构建进行初步探究:原告资格以工会、妇女联合会等社会组织为主,新增专门的平等就业管理机构;举证责任在当事人之间合理分配;抗辩事由应包括劳动保护措施、真实职业资格、小微企业豁免制度等;法律责任形式从民事责任和行政责任两方面进行规范。     

小微企业和谐劳动关系构建的财政扶持政策研究

小微企业存在着大量的体面劳动赤字,要构建和谐劳动关系面临着许多现实困境。除了促进劳动法在小微企业的有效实施外,还应该通过财政扶持政策促进小微企业和谐劳动关系的构建。这些具体的财政扶持政策包括就业岗位、工会会费、劳动安全卫生、企业培训、社会保险费的财政补贴政策以及劳动关系规范化管理的财政激励政策。     

《劳动合同法》主要问题的经济研究评介

《劳动合同法》是继《劳动法》之后,关于改善劳动关系的重要法律文本。随着经济增长趋于平缓,关于《劳动合同法》的修订和废止问题再次引起理论界的深入讨论。文本从经济理论研究的角度对《劳动合同法》执行中关于灵活用工问题、劳动力成本和劳动生产率三个主要经济争论进行梳理和分析。研究发现,我国劳动力成本增长低于劳动生产率的提高,《劳动合同法》的实施并不会对员工工资产生显著影响,也不会显著影响劳动生产率。     

绿色发展视角下的健康适度劳动问题

推行绿色发展战略是国际经济发展的新趋势,也是我国经济良性发展、实现十九大所提出的"两步走"战略目标的必然选择。发展绿色经济离不开其价值源泉——绿色劳动,绿色劳动的思想可以追溯至亚当·斯密、马克思和舒尔茨,ILO的体面劳动、企业社会责任、现代化、知识经济、现代社会保障都蕴含着绿色劳动的思想。目前我国在社会劳动领域存在很多问题,推动劳动的健康绿色化,需要政府积极地引导推动、企业树立新的用人理念、工会努力发挥有效维权的作用,并需要多方面借鉴国际有效经验。
