Thematic elements underlying the delivery of services in high-contact public service encounters

Earlier research alludes to the fact that enhanced information and systems (IS/IT) functionalities coupled with a lower degree of interaction with customers, the so-called zero- touch, real- time, self-service enhance services engagement. In this article, utilising a series of thematic elements drawn from two exploratory case studies, the authors suggest that the real enhancement of service delivery and increase in customer satisfaction, especially in frontline public service encounters, are not necessarily achieved through infusions of IS/IT, but from the adoption of a service philosophy which allows such organisations to de-emphasise IS/IT and instead focus on significant organisational factors in the area of enhanced human interaction.     

不确定需求下考虑资金约束的生鲜农产品政府补贴策略

针对需求不确定环境下政府如何对生鲜农产品供应链进行补贴的问题,在考虑财政资金的约束下,分别构建了无政府补贴、采购补贴和销售补贴三种情形下的博弈模型。通过对比分析得出了政府的最优补贴策略,并分析了补贴策略对生鲜供应链最优决策的影响,最后用数值算例进一步说明了不同补贴策略对不同类型生鲜农产品的影响。研究发现,补贴策略的选择与财政预算密切相关。在财政预算充裕时,两种补贴策略都有效且可行,都能平抑物价、增加供给、拉动需求;从改善社会整体福利的角度,采购补贴为最优策略;从补贴资金效率的角度,销售补贴为最优策略。在销售补贴预算充裕而采购补贴预算存在缺口时,销售补贴为最优策略。在财政预算不足时,政府的最优策略就是不干涉市场的运营。     

The impact of social transformation on the non-government welfare sector and the social work profession

This article examines changes to non-government social welfare, their impact on service delivery and on the social work profession. To redress the legacy of the past and the consequent inequalities in social welfare, in the first decade of democracy the government allocated the bulk of its welfare resources to transforming the social security system at the expense of social service delivery. As a result, South Africa has a costly social security budget with social services on the brink of collapse, leaving social workers and other social service professionals with low morale in the face of the huge challenge of providing welfare services with scarce resources, especially in the non-government sector. Nevertheless, social work remains an important role player in social development. From its marginalised position in the first decade of democracy, in the second decade it is repositioning itself as a recognised contributor to reconstruction and development in South Africa.

孔子"辞达而已"的语言学解读

孔子言语简约,一句“辞达而已矣”曾引起后人的极大关注。后世学者从不同角度阐释了“辞达”,见仁见智。就语言的运用而言,“达”指表达、传达,也可指畅达、通达,还可指理解上的通晓、明白;它不刻意求“工”,但也不反对文饰。孔子的言语理论和言语实践也说明了这一点。所以孔子的“辞达”,绝非单一的传达、表达或通达、明白之意,而是“达其所欲达以期于达”的简略表述;它涵盖了言语动机、方式方法、目的效果等多个层面,蕴含了传情达意、表达流畅、兼求修饰、通晓易懂等多个意思。     

Integrating commercial and residential pickup and delivery networks: A case study

This paper presents a strategic analysis of the network design problem faced by pickup and delivery companies operating in metropolitan areas and serving two or more classes of customers. The focus is on a division that treats commercial and residential customers separately, a situation motivated by their respective geographic densities and the size and frequency of their demand. In constructing driver work areas, it is necessary to take into account expected demand, vehicle capacity, time on the road, and the aspect ratio of the individual territories. This leads to a capacitated clustering problem with side constraints that has been the subject of intense research over the last decade.     

对方案有偏好的不确定语言多属性决策方法

研究了属性权重完全未知、属性值和对方案的偏好值以不确定语言变量形式给出的不确定语言多属性决策问题。首先,引入不确定语言变量的运算法则,以及不确定语言变量之间比较的可能度公式,给出了不确定语言变量间的距离的概念。针对属性权重完全未知的情形,给出了求解权重的公式。然后,利用不确定语言加权平均算子,对不确定语言决策信息进行加权集成,并利用可能度公式构造可能度矩阵(互补判断矩阵),继而利用互补判断矩阵排序公式对决策方案进行排序和择优。最后进行了实例分析。     

电子市场中时间价格敏感需求下的交货期定价决策

电子市场中,如何通过交货期报价来增大需求、提高收益,对于网络营销企业来说是至关重要的.本文假定在一个包含网络营销企业与其客户的运作系统中,需求同时对价格与时间都敏感的条件下,以最优化自身收益为目标、以满足必须达到规定的服务水平为主要约束条件,构建了交货期定价决策模型.通过数值算例,探讨了在电子市场中消费者为价格敏感或交货期敏感时,网络营销企业的最优定价策略.上述结论可以为网络营销企业在电子市场中的定价决策提供有益的指导.     

不确定需求下闭环供应链定价模型研究

构建了不确定需求下1个制造商与1个销售商组成的具有产品再造的闭环供应链定价模型.利用博弈理论对2种定价模型进行了分析,得到了一些结论.进一步通过数值仿真定量分析了各模型中新产品制造成本变化对废旧品回收价格、市场销售价格和系统及其成员利润期望值的影响.比较2个定价模型发现集中决策的市场回收价格高于分散决策,销售价格低于分散决策,销售量大于分散决策,系统的利润期望值大于分散决策.
