Globally, an estimated 734 million jobs will be required between 2010 and 2030 to accommodate recent and ongoing demographic shifts, account for plausible changes in labour force participation rates, and achieve target unemployment rates of at or below 4 per cent for adults and at or below 8 per cent for youth. The facts that most new jobs will be required in countries where “decent” jobs are less prevalent and workers in many occupations are increasingly subject to risks of automation further compound the challenge of job creation, which is already quite sizable in historical perspective. Failure to create the jobs that are needed through 2030 would put currently operative social security systems under pressure and undermine efforts to guarantee the national social protection floors enshrined in the Sustainable Development Goals (SDGs).  相似文献

Objective: The objective of this study was to understand substance use patterns of alcohol, marijuana, and simultaneous alcohol and marijuana (SAM) use among 2- and 4-year college students. Participants: Participants were 526 young adults aged 18–23 (n?=?355 4-year students; n?=?171 2-year students) recruited from February 2015 to January 2016 who were participating in a larger longitudinal study. Methods: Latent class analysis (LCA) was used to identify past-month classes of alcohol, marijuana, and SAM use. Results: Among both 2- and 4-year students, a four-class solution yielded the best-fitting model, with 2-year classes tending to include greater marijuana use and less alcohol use and 4-year classes tending to include heavy alcohol use. Demographic characteristics were largely similar across classes. Conclusions: Classes of alcohol, marijuana, and SAM use differed by education status. Screening and prevention efforts for 4-year students may need to be tailored for the needs of 2-year students.  相似文献

Simulation results are reported on methods that allow both within group and between group heteroscedasticity when testing the hypothesis that independent groups have identical regression parameters. The methods are based on a combination of extant techniques, but their finite-sample properties have not been studied. Included are results on the impact of removing all leverage points or just bad leverage points. The method used to identify leverage points can be important and can improve control over the Type I error probability. Results are illustrated using data from the Well Elderly II study.  相似文献

四川盆地卤水分布广泛,资源丰富, 早为世人所瞩目,中三叠统雷口坡组是四川盆地最早开采天然气和盐卤的层系之一。根据盆地雷口坡组大量钻井资料研究表明,盆地雷口坡组主要成盐期分别为雷三2 期和雷四2 期,在盆地东部和南部由于受到古隆起的影响,盐岩地层已被剥蚀难以保存,现今盐岩主要分布在开江古隆起和泸州古隆起的西部以及天井山古隆起的南部(华蓥山以西—龙门山以东的川西—川中地区)。印支运动对盆地雷口坡组盐岩在平面的迁移起着十分重要的作用,根据不同时期盐岩统计数据看,两期盐盆在平面上具有向西迁移、叠加的特征,其中川中的GS1 井就钻遇了这两期的盐岩。  相似文献

本研究以68名幼儿为研究对象,运用《游戏检核表》对其社会戏剧游戏水平进行调查,研究发现:4-6岁幼儿角色扮演、口语交流、互动和同伴支持水平高,游戏时间充分;但物品假装、如何进入游戏小组、问题解决和轮流技能较低。教师应通过明确自身角色、丰富幼儿游戏材料和经验、提升幼儿语言能力和社会交往技能促进幼儿社会戏剧游戏发展。  相似文献

华北油田是我国最早发现古潜山海相碳酸盐岩油气藏的地方,也是产量骤起骤降幅度最大的一个油田,它的勘探过程中蕴含着太多丰富的经验值得总结.从任4井发现的细节入手进行回顾,对华北油田勘探经验中的古潜山、碳酸盐岩、震旦系灰岩等关键问题进行了深入思考.指出按有机成油论的学说很难将华北油田的历史经验深入总结下去,应按无机成油论的观点,对华北油田的历史经验进行再认识.  相似文献

BackgroundSevere perineal tears sustained during childbirth cause significant distress and morbidity amongst women. The objective of this study was to compare the use of straight scissors for cutting an episiotomy with the use of curved scissors, which are designed to curve away from the anal sphincter.MethodsWe used a single-centre, randomised feasibility trial. The intervention was the use of curved scissors. Women were recruited during a prenatal visit and randomised in the delivery suite, when it became clear that an episiotomy was required. The feasibility outcomes were the proportion of women able to be recruited, randomised and followed up. We also calculated the incidence of obstetric anal sphincter injury when either straight or curved scissors were used to cut an episiotomy. Other outcomes assessed were pain, length of hospital stay, perineal infection and perineal dehiscence.ResultsOf the 155 patients recruited in the prenatal period, only 20 (12.9%) were eventually randomised at birth. The main reasons for the high loss were that women either did not have a vaginal delivery (38, 24.5%), or they did not need an episiotomy (72, 46.5%). Rates of obstetric anal sphincter injury and other outcomes were similar between groups.DiscussionAnal sphincter injury during childbirth remains an important problem. Although the use of curved scissors provides a theoretical solution, we found that the high attrition rate made feasibility of conducting a suitably powered, randomised trial using the current design untenable. Alternative strategies have been suggested to make any future study more viable.  相似文献

More often than not, the existing modes of contribution collection and benefit payment of social security organizations are adapted to the collective arrangements that characterize employer‐employee relationships. Extending coverage to individuals in difficult‐to‐reach groups, however, may require new modalities of service that can cope with many separate, secure transactions rather than a few bulk data transfers between organizations. Recent developments in electronic payment show its wide applicability in enabling huge volumes of such individual transactions. It is in this light that the article explores the potentials of this technology and identifies possible arrangements through which electronic payments could surmount barriers that stand in the way of covering difficult‐to‐reach groups. The high level of mobile phone penetration on a global scale augurs well for using e‐payment mechanisms to collect social security contributions and to deliver social security benefits and services. A generic model is used to describe the requisite elements to implement electronic payments in social protection programmes. Based on empirical evidence of current social protection practices from around the world, five scenarios are presented to describe possible configurations for electronic payment, from the simplest to the most sophisticated. The broader objective is to contribute in a practical manner to the international commitment to extend social protection to all, as defined by the 2030 Sustainable Development Goals.  相似文献

The authors offer a contextualized analysis of judicial decisions rendered during 1971–2013 in Côte d'Ivoire, where domestic work is regulated by a general labour code. Assessments of those decisions, alongside qualitative interviews of institutional actors, elucidate how innovative practices were mainly derived from the code by attentive inspectors and by jurisprudence evolving to treat domestic work like any other. Yet limitations emanating from the inability to grapple with the specificity of domestic work are also identified. Reaffirming that the regulation of domestic work must embrace its duality (work like any other and work like no other), the authors conclude with a call for an international community of learning on decent work for domestic workers.  相似文献

Article 4 of the Labor Contract Law lays down the right of the Staff and Workers’ Representative Congress (SWRC) to deliberate on the formulation of (intra-enterprise) work regulations, but this has become a “soft” law in judicial practice. The judicial criteria for judging the validity of work regulations are in essence determined by the judge’s judgment on their reasonableness. As an important embodiment of Chinese politics, economics and culture, the transformation of the SWRC that accompanied the market economy has not negated its value as an indigenous traditional resource. The SWRC does not just enjoy deliberative rights in the formation of regulations, as clearly specified in constitutional law, but also has rights under the law in local legislation and practice. Hence the system of work regulations is neither a unilateral decision on the part of management nor a contract, but rather an autonomous norm developed through the SWRC mechanism. Given the mandatory nature of Article 4 of the Labor Contract Law, regulations will only be valid after they have gone through a democratic process. The further development of the theory of normative system formation should endow the SWRC with greater rights and integrate it smoothly with the collective contract system to standardize collective labor relations.  相似文献
