随着劳动力价格上涨,制造业企业人口红利逐渐消失,以互联网、人工智能提升改造传统产业的同时,推动“技术红利”替代“人口红利”,成为制造业企业优化升级的必然选择。技术创新在促进经济发展的同时是否加剧了技能短缺?考察技术创新对技能短缺的影响作用,结果表明:技术创新对企业技能短缺产生了显著的正效应,研发支出增加了对技能劳动力的需求,并且伴随企业规模扩大、技能劳动力比例上升,技能短缺程度加剧。同时,技术创新对技能短缺在区域和产业上存在显著异质性。在超大城市中,技术创新对技能短缺的拉动作用更为显著。在中小城市,技术进步效应并不显著;而技术创新对制造业技能缺口的影响效应也显著强于服务业,进一步验证了技术创新水平的快速提升使现有技能水平无法与之相匹配,加剧了企业技能结构性短缺。  相似文献

药品安全关乎人民群众生命健康、经济发展、社会稳定和国家安全,一直以来都是政府和全社会关注的热点问题之一。但是,近年来频发的各类药品安全事件,揭露了政府监管缺失、药品检测机制不完善、公众投诉失效等诸多问题。本文考虑了药品检测中存在寻租现象,构建了药品生产企业、第三方药品检测机构和政府监管部门之间的三方演化博弈模型,分析了各参与方策略选择的演化稳定性,探讨了各要素对三方策略选择的影响关系,进一步分析了三方博弈系统中均衡点的稳定性。研究结果表明:1)政府增强奖励、惩罚力度均有助于促进企业生产高药效药品、第三方药品检测机构拒绝寻租的规范行为,但是增大奖励力度将不利于政府自身履行监管职责;2)政府设定合理的奖惩机制必须符合对各方的奖惩之和大于其投机收益的条件,才能保障演化稳定市场环境下的药品安全;3)上级政府对监管部门失职的问责对增强企业生产高药效药品的稳健性具有重要意义;4)提升企业的药品销售收益、增加企业寻租成本也是避免企业生产低药效药品的有效途径。最后,利用Matlab 2020b进行了仿真分析,为政府完善药品监管机制提出了对策与建议。  相似文献

ABSTRACT

Past research has consistently reported a higher rate of drug use before arrest among incarcerated inmates than that of the general population. However, there is a lack of either qualitative or quantitative research on this topic under the Chinese setting. Drawing upon survey data collected from 1,518 inmates in a Chinese province, this study attempts to fill in the research gap by assessing the connection between risk factors associated with pre-arrest use. Roughly a quarter of all inmates in the sample had the experience of drug use before arrest. Regression analysis suggested that impulsivity, volatile temper, and perceived prevalence of drug use in neighborhood were significantly related to drug use among inmates. Two control variables include offense type and stable job, were also found to be significant predictors of drug use. Implications for research and policy were highlighted in the end.  相似文献

This study explored the case of a former addict, focusing on his existential self‐interpretation and identity transformation process. This study began from the question of whether philosophical processes related to existential self‐interpretation could lead to the formation of the concept of bottoming out and of identity transformation. To answer this question, the study analyzed the case of a male in his mid‐forties who was addicted to drugs for approximately 30 years and has only recently maintained abstinence. The study used the phenomenological approach to determine the meaning drugs held for him in each stage, and what drug‐related identity he had in each stage. Further, this study identified the integrative implications of these meanings in terms of existential self‐interpretation and identity transformation. The four different identities the man identified for the four stages of his life were juvenile delinquent, gang member, half‐gangster, and breadwinner, and the associated meanings drugs had for him during each period were “glue,” “filthy,” “leeches,” and “abstinence,” respectively. Finally, this study elucidated the integration of these meanings through the hermeneutic circle, identified the social welfare implications of the findings, and developed educational recommendations.  相似文献

发展现代远洋渔业是党的十八大提出的建设海洋强国的战略需求,而远洋渔业人才的培养则是促进远洋渔业可持续发展的重要保障。应采用理事会管理、“订单式”培养远洋渔业紧缺人才;行业主管部门、产业部门、学校和学生四方应协同,形成政府宏观调控、企业需求有保证、学校积极培养、学生愿意选择的良性循环;企业至少提前2年下“订单”,由学院、企业共同选拔学生,进行为期二年的“订单式”强化培养;校方应将强化培养教学内容纳入教学计划中,作为专业方向来培养;应多层次、多方面和多专业培养远洋渔业紧缺人才。  相似文献

本文基于人力资源管理价值链的视角,分析了政府和企业在农民工这一特殊人力资源类型的价值创造、价值评价和价值分配的三个环节管理中存在的问题。这些问题最终导致了"用工荒"现象的产生。政府层面存在的主要问题有:在价值评创造环节中,缺乏对低端劳动力群体的规划、建立统一的劳动力市场和对农民工技能培训经费的投入不足;在价值评价环节,缺乏对技能人才的评价机制;在价值分配环节,对农民工利益保障的立法不完善且执法不严。企业层面存在的主要问题有:在价值创造环节,只重使用,不重培养;在价值评价环节,缺乏多种评价手段;在价值分配环节,企业发放给农民工的薪酬福利低,针对以上问题,从政府和企业两个层面,提出了相应的解决对策。  相似文献

ABSTRACT

The illicit drug crops opium and coca are conventionally regarded as sources of instability, an ‘evil’ that breeds fragility and violence. Fragile states are supposed to be most vulnerable to their production and consequent harms. Yet by looking into the local contexts of the world’s leading opium and coca producers – Afghanistan, Myanmar, Colombia and Bolivia – these illicit crops are found to also be sources of stability, even drivers of economic growth. They enable marginalized communities and territories abandoned by the state to be reinserted into national and global markets. Within so-called ‘fragile’ and conflict-affected areas are displaced and dispossessed households adopting innovative and unorthodox strategies for coping and survival in changing and insecure environments. This paper maps out an approach, useful for examining the resilience that has emerged amidst violence and uncertainty in illicit-crop-producing territories, and which can hopefully tackle the continuing disconnect between drugs and development policy.  相似文献

The study of drug synergy plays a prominent role in the search for drug combinations with beneficial interactions. Firstly, in this process, the drug-effect response of individual parts and the mixture needs to be derived. This function is usually well described by Hill (or other logistic or sigmoid) curve. Due to its boundedness, it allows the measured data to be normalized. The normalized data can then be processed by interaction analysis using the Loewe, Bliss, or other models to evaluate possible synergy or antagonism of two or more drugs. However, sometimes, the drug-effect responses observed in pharmaceutical research do not appear to be bounded. Theoretically, the drug-effect curve cannot grow to infinity, but it may be impossible to determine its upper bound within the observed region. In this case, standard models cannot be used, since they assume that data are normalized. The approach of this article bypasses the need to normalize the data, allowing its broader application and usefulness in finding potential synergies in pharmaceutical research.  相似文献

This study analyzes three years of data on misdemeanor drug offenders in Winnebago County, Wisconsin. A portion of these offenders opted into a Misdemeanor Drug Diversion Program (MDDP) offered instead of traditional adjudication. Recidivism in the treatment and comparison groups is estimated using standard binary response techniques augmented with propensity score matching to address selection bias. Results show that the MDDP reduces the probability of re-offense by 16%, after adjusting for possible selection bias. Cox proportional hazard modeling is also used to assess time-to-re-offense differentials between the treatment and comparison groups. The survival analysis indicates that the hazard rate of re-offense is 60% lower per day among those treated with the MDDP program than those who did not complete the program. The average number of days to re-offense among those that do re-offend is 297 days in the treatment group and 203 days in the comparison group.  相似文献
