政府购买居家养老服务的探索与发展——以济南市历下区为例

基于济南市历下区购买居家养老服务的实践,探讨了社区居家养老服务的时代背景,重点分析了历下区政府购买居家养老服务的运作模式,研究结果表明,在我国养老压力日益严峻的情况下,要完善政府购买居家养老服务模式,必须积极推进社区居家养老服务产业的发展;加大政策扶持力度,加强资金引导;培育社会组织,提高养老服务品质;实现政府购买居家养老服务的标准化运作,只有这样才能缓解养老压力,提高老年人生活质量,推动养老服务事业的发展。     

Gap and Integration - Volunteer Service for Western China and College Students＇ Growth

大学生志愿服务西部计划的目的之一是大学生通过奉献社会来实：观个人成长。他们能否真正地成为当地社会中的一员,是实现这一目的的关键。在异文化环境之中,想短时间内成为其中一员并非易事,因为有一道浅浅的沟壑存在于青年文化与当地文化、当地人与外来人、青年人与长辈之间。为实现志愿服务效果的最大化,西部志愿者应该积极主动地融入当地社会．当地社会应对他们抱持开放的态度,他们与当地长辈之间应该展开对话,他们更应该战胜和超越自我。     

The implementation of digital technologies for operations management: a case study for manufacturing apps

Abstract

Manufacturing applications address business to business (B2B) with highly customised applications developed for specific requirements, offering highly specialised solution-oriented and service-based software components, systems, and digital tools that aim at a fast and accurate decision-making support system. The purpose of this paper is to describe the implementation of digital technologies for operations management using manufacturing or engineering apps (eApps), for product design and manufacturing processes. In particular, starting from the specific needs of two companies from mature European industries as automotive and food, this work depicts how this kind of solutions can support companies and improve their operations. In particular, related benefits and challenges faced for the full implementation of the developed tools are highlighted. Moreover a business model to exploit the manufacturing apps is also proposed. The business model proposed for the exploitation of the eApps supports the commercialisation of all the revenue streams offered by this rapidly growing sector taking into account the specific needs of the concerned stakeholders through a diversified value proposition.     

光滑暧昧模型下的不透明交易和管制措施研究

本文假定透明交易者对额外投资机会回报率的标准差(方差,投资风险)存在暧昧,这种认知暧昧性抑制了透明交易者的投资行为,会导致风险资产溢价过高及社会福利损失.透明交易者是暧昧厌恶的投资者,其投资决策依据光滑暧昧厌恶模型,需求函数呈现连续且光滑的特征.而不透明交易者,通过支付一定的信息获取成本获得私有信息而具有信息优势,他们是标准的风险厌恶的投资者.通过构建理性预期均衡,本文的研究发现:初始资产严格为正的透明交易者将获得严格为正的超额收益;提高信息获取成本将减少不透明交易者的比例,从而增加风险资产溢价,降低福利水平,因而不是一项好的管制措施;而旨在提高市场透明度降低交易者暧昧性的举措总有利于提高福利水平.     

A Bayesian sequential design with binary outcome

Several researchers have proposed solutions to control type I error rate in sequential designs. The use of Bayesian sequential design becomes more common; however, these designs are subject to inflation of the type I error rate. We propose a Bayesian sequential design for binary outcome using an alpha‐spending function to control the overall type I error rate. Algorithms are presented for calculating critical values and power for the proposed designs. We also propose a new stopping rule for futility. Sensitivity analysis is implemented for assessing the effects of varying the parameters of the prior distribution and maximum total sample size on critical values. Alpha‐spending functions are compared using power and actual sample size through simulations. Further simulations show that, when total sample size is fixed, the proposed design has greater power than the traditional Bayesian sequential design, which sets equal stopping bounds at all interim analyses. We also find that the proposed design with the new stopping for futility rule results in greater power and can stop earlier with a smaller actual sample size, compared with the traditional stopping rule for futility when all other conditions are held constant. Finally, we apply the proposed method to a real data set and compare the results with traditional designs.
