2020年香港经济形势分析及未来展望

报告从宏观层面对2020年香港经济形势进行了分析,对2021年香港经济发展前景做了展望,对香港经济中期发展面临的风险和机遇进行了研判,并提出了一些对策和建议。分析表明,香港经济在2020年陷入深度衰退,在2021年将迎来复苏,复苏程度取决于疫情防控状况。香港经济未来几年的发展风险与机遇并存:一方面,中美竞争加剧、社会贫富差距加大、政府财政赤字持续等是不利因素;另一方面,我国"十四五"规划的出台和粤港澳大湾区建设的深入推进将帮助香港进一步融入国家发展大局,获得更广阔的发展空间。     

乡镇政府存在的合理性探析--基于新农村建设的语境分析

长期以来,我国乡镇政府及其机构显露出种种弊端。在党中央提出建设社会主义新农村的新形势下,乡镇政府何去何从成了一个值得关注的重要问题。乡镇政府存在的合理性在于乡村社会对其的“需求”。新形势下,乡村社会对乡镇政府提出的职能诉求有:其一,乡镇政府应扮演政策的发布者和执行者的角色;其二,乡镇政府应扮演新农村建设具体工作的组织者、推动者和操作者;其三,乡镇政府担负着预防和治理农村政治危机的职能;其四,从人力资源开发与管理的维度看,乡镇政府承担着开发农村人力资源的重要任务;其五,乡镇政府还应具有农村公共安全管理职能。     

Postmortem chest computed tomography for the diagnosis of drowning:a feasibility study

It may be difficult to distinguish the cause of death in drowning cases without specific findings. The aim of this study was to explore the forensic value of thoracic postmortem computed tomography (PMCT) using routine images and three-dimensional (3D) image reconstructions. The imaging data of PMCT examinations of six drowning cadavers, aged 21–54 years, were analyzed. Twelve victims of sudden death from coronary artery disease (CAD) were chosen as a control group. After 3D bilateral lung images were reconstructed using image processing software, an interactive medical image control system was used to measure and analyze parameters including lung volume, lung volume ratio, mean CT value of the whole lung, and lung CT value distribution curves. Lung volume and lung volume ratio were used to assess the shape changes of the lung. Lung CT value distribution curves showed the corresponding number of pixels of the different CT values in the lung image. Lung volume was not significantly larger in drowning cases (mean 2 958 cm³) than in controls (mean 2 342 cm³). Lung volume ratio values in the drowning group (mean 0.3156) were greater than those in the control group (mean 0.2763); (P = 0.02). There was no significant difference between the drowning and control group in the mean CT value of the whole lung. There were differences between lung CT value distribution curves in drowning victims and controls, with drowning victims showing a single peak and CAD cases showing a bimodal distribution. Thoracic PMCT is helpful for the forensic medical diagnosis of drowning. Lung volume ratio and lung CT value distribution are potential indicators to distinguish between drowning and CAD.     

日本公明党与中日邦交正常化

中日邦交正常化的政治过程,是一个显示日本对外政策与国内政治相互关系的典型事例。在这一过程中,包括公明党在内的日本各在野党发挥了非常重要的独特的“补充外交”作用。特别是公明党领导人竹入义胜等非政府人士的访华,为日本政府摸清中方意图、沟通两国领导人之间的看法、形成复交文件等发挥了极为重要的作用。当然,中国政府也充分认识到日本在野党在日本政治生活中的重要作用,并积极开展对日本在野党的工作,从而推动日本执政党转变对华政策。

个人大病求助互联网服务平台行政规制研究——以水滴筹为例

个人大病网络互助是目前我国应用最为广泛的个人求助形式,一定程度上能够弥补慈善组织社会救助之不足。实践中,个人大病求助互联网服务平台暴露出诸多问题。应从确立监管主体、明确权利义务、开立专门账户、设立第三方基金会、提高准入退出门槛等方面加强对个人大病求助互联网服务平台的行政规制,以营造良好的慈善氛围。     

Evaluating the Potential for Unintentional Occupational Exposure to Fentanyl and Fentanyl Analogues Among Medicolegal Death Investigators and Autopsy Technicians

Recent increases in deaths in the United States from synthetic opioids such as fentanyl and fentanyl analogues (fentanyls) have raised concerns about possible occupational exposures to these potent agents. Medicolegal death investigators and autopsy suite staff might perform job tasks involving exposure to fentanyls. The potential for exposure to fentanyls among medicolegal death investigators and autopsy technicians at a state medical examiner's office was evaluated through review of caseload characteristics, injury and illness logs, and procedures and policies and discussions with management and employee representatives. The evaluation showed that this medical examiner's office had low potential for work-related exposure to fentanyls; its standard operating procedures and personal protective equipment requirements should reduce the potential for occupational exposure. Medicolegal death investigation agencies can develop and implement guidance to control exposures and provide workforce education and training to reduce the potential for work-related exposure to fentanyls.     

北京市流动人口服务管理基层工作的模式与困境

综观北京市流动人口服务管理基层工作模式,从管理主体来看,可分为网格包干型、三级联管型.村企联管型和依托协会型四种;从出租房屋主来看,可分为契约自治型、双向关联型和旅店式管理型三种;从流动人口居住和从业特点来看,可分为企业集中管理型、产业升级过滤型,大院委托管理型和居干搂长协助型四种.当然,不管哪种工作模式,其实施均会遇到来自管理主体的人员-资金-设施困境、"执法权"缺乏困境、管理员本地化困境和来自管理客体的流动人口融合困境、流动人口不配合困境、流动人口流动性困境、出租房屋主搭便车困境的制约.     

论高校图书馆信息资源布局和信息资源服务

高校图书馆利用先进的科学技术,应充分发挥信息资源库的作用和价值。提供优质高效的信息资源服务有赖于图书馆信息资源的合理布局。图书馆信息资源布局实行开架制三线典藏较为合理。信息资源服务的方法主要有用户研究与用户培训、文献借阅服务、参考咨询服务、馆际互借和文献传递等。高校图书馆信息资源建设制度化才能促进图书馆信息资源服务规范化。
