我国人口老龄化的城乡差异及影响因素分析

人口的乡—城转移导致了老龄化城乡倒置现象,人口的单向跨区域流动也造成了我国大范围的地区年龄结构失衡,对我国的经济社会可持续发展造成威胁。基于2010—2019年大陆31个省市的面板数据,以人口老龄化系数为被解释变量,分别构建固定效应和随机效应模型,从人口、经济、社会三个方面研究我国城镇、农村人口老龄化和城乡倒置现象的影响因素以及三类因素在东、中、西部地区的不同表现。结果显示,人口因素是老龄化城乡差异的直接原因,经济因素是根本原因,教育、医疗、社会保障等社会因素在城乡、区域之间影响不一。为此,政府应当增强生育支持力度以提高生育率,推动城乡一体化发展,推动农村地区的养老服务建设,并鼓励区域的联动合作,以缓解老龄化集聚地区的人口压力。

Gender differences in risk behavior and the link to household effects and individual wealth

This study examined the differences in risk behavior between men and women using a household survey that captured the risk preferences of two members in a household and recorded wealth at the individual level instead of the usual approach of representing wealth at the household level. After controlling for commonly used explanatory variables, such as gender, education, age, and wealth, household fixed effects explain about 15% of the variation in risk behavior. This highlights the magnitude of household effects in shaping one’s risk behavior. In general, females in the study area are more risk averse than males based on a risk game with real payout. The gender differences disappear when focusing on only the top land owners. However, even in those cases, females consider themselves more risk averse, supporting results from previous studies that link culture and societal norms to the gender differences in risk behavior.     

The experiences of privately practising midwives in Australia who have been reported to the Australian Health Practitioner Regulation Agency: A qualitative study

BackgroundIn Australia the majority of homebirths are attended by privately practising midwives (PPMs). In recent years PPMs have been increasingly reported to the Australian Health Practitioner Regulation Agency (AHPRA) mostly by other health professionals.Purposeto explore the experiences of PPMs in Australia who have been reported to the AHPRA.MethodsA qualitative interpretive approach, employing in-depth interviews with eight PPMs was undertaken and analysed using thematic analysis. A feminist theoretical framework was used to underpin the research.ResultsThe majority of reports made to AHPRA occurred when midwives supported women who chose care considered outside the recommended Australian College of Midwives (ACM) Consultation and Referral Guidelines. During data analysis an overarching theme emerged, “Caught between women and the system”, which described the participants’ feelings of working as a PPM in Australia. There were six themes and several sub-themes: The suppression of midwifery, A flawed system, Lack of support, Devastation on so many levels, Making changes in the aftermath and Walking a tight rope forever. The findings from this study reveal that midwives who are under investigation suffer from emotional and psychological distress. Understanding the effects of the process of investigation is important to improve the quality of professional and personal support available to PPMs who are reported to AHPRA and to streamline processes.ConclusionIt is becoming increasingly difficult for PPMs to support the wishes and needs of individual women and also meet the requirements of the regulators, as well as the increasingly risk averse health service.

后现代主义思潮与大学生价值观嬗变

进入新时期以来,在西方后现代主义思潮的浸染下,我国大学生的价值观发生了嬗变:由单一向多元转变、集体向个人位移、理想向世俗变动,甚至呈现出与我国社会主义核心价值观相背离的风险。后现代主义语境下的这一嬗变,因循于社会结构的变迁和大学生思维的非真实化变动,并深刻地受到大众传媒低俗化的影响。面对大学生价值观取向的变迁,引导大学生正确认识后现代主义思潮、强化大学生价值观再培育、发挥社会主义核心价值观的整合作用显得尤为重要。     

商业信用风险管理绩效影响因素的实证分析

近年来,Jianmin Jia等学者对"我国信用风险管理现状"及其相关问题进行研究,取得一定的研究成果,但相应研究中存在着"简单使用线性回归,未能消除变量间的相互影响"等局限。基于对已有相关研究成果的评析,并运用因子分析和Pearson相关分析方法,对我国商业信用风险管理绩效的影响因素进行实证研究。研究表明:商业信用风险管理绩效的关键影响因素为"信用管理职能设置"、"客户资信评估"和"信用政策制定",我国企业应从"完善信用风险管理职能"、"改善信息不对称状况"和"提高信用政策制定水平"三方面提高风险管理绩效。

Reliability acceptance sampling plans for the Weibull distribution under accelerated Type-I censoring

Type-I censored reliability acceptance sampling plans (RASPs) are developed for the Weibull lifetime distribution with unknown shape and scale parameters such that the producer and consumer risks are satisfied. It is assumed that the life test is conducted at an accelerated condition for which the acceleration factor (AF) is known, and each item is continuously monitored for failure. Sensitivity analyses are also conducted to assess the effect of the uncertainty in the assumed AF on the actual producer and consumer risks, and a method is developed for constructing RASPs that can accommodate the uncertainty in AF.
