我国劳动力流动的动态和预期经济效应分析

劳动力流动是市场机制发挥配置资源作用的表现。从静态分析看,劳动力流动调剂了供需双方缺口,提高了整个社会福利水平。从动态角度看,我国的中心城市和经济先发展地区具有吸引资金、技术和知识资本的优越条件,决定着劳动力流动方向,而且因累积循环作用,引起回波效应大于扩散效     

基于CFD-DEM的渗蚀研究:细粒含量与围压的影响

为了揭示渗透水流对砂土渗蚀破坏的规律,利用流固耦合方法(CFD-DEM)建立具有应力边界的长方体砂土试样,进行了不同围压和细粒含量条件下间断级配砂土的渗蚀模拟.结果表明,1)对于高细粒含量试样,围压越高渗蚀颗粒流失量越高,但对于低细粒含量试样,围压对渗蚀的促进作用并不明显.2)当细颗粒含量较高时,细粒流失会引起力链屈曲...

金刚石纳米粉引晶方法制备金刚石薄膜方法

利用金刚石纳米粉引晶法和常规研磨方法分别在单晶硅衬底上制备金刚石薄膜,并采用扫描电镜、激光拉曼方法对所制备样品进行表征,通过SEM和拉曼谱分析,与研磨法生长金刚石薄膜相比,利用金刚石纳米粉引晶方法可以大大提高金刚石薄膜的成核速度,生长速率达到2μm/h以上。对相同碳源浓度下生长的金刚石薄膜样品的SEM和拉曼谱分析,采用引晶法生长的金刚石薄膜质量明显高于研磨法。     

Processes underlying the development and evolution of salespersonsõ job satisfaction/dissatisfaction: a conceptual framework

A conceptual framework of salesperson satisfaction/dissatisfaction is presented and is used to develop several research propositions. Drawing from organizational behaviour and sales management research, the model incorporates various theories of motivation and emphasizes the role of intervening variables thought to be especially important in the context of sales occupations. Finally, the model draws attention to the dynamic nature of the relationships between salespersons' efforts, performance, intrinsic and extrinsic rewards, and job satisfaction/dissatisfaction.

Strategic and organisational determinants of sophistication in deployed sales force automation systems within three industry sectors in the UK

Abstract

This paper investigates strategic and organisational context determinants of the sophistication of adopted sales force automation (SFA) systems in three UK industries: financial services, pharmaceuticals, and building/construction. Sophistication of adopted systems is associated with the organisation placing greater emphasis on information orientation, which is itself driven by an increased integration of IT and sales coupled with increased organisational slack. Increased integration of IT and sales is itself driven by increased strategic importance of sales coupled with increased use of internal communication networks. Importantly, a firm's marketing orientation, although also driven by the strategic importance of sales, has no impact on either information orientation or SFA sophistication. We discuss the implications of our findings to aid understanding of SFA implementation failure.     

A practical solution to the problem of ultimate ruin probability

Abstract

It was the Swiss actuary Chr. Moser who, in lectures at Bern University at the turn of the century, gave the name “self-renewing aggregate” to what Vajda (1947) has called the “unstationary community” of lives, namely where deaths at any epoch are immediately replaced by an equivalent number of births. It was Moser too (1926) who coined the expression “steady state” for the stationary community in which the age distribution at any time follows the life table (King, 1887). With such a distinguished actuarial history, excellently summarized by Saxer (1958, Ch. IV), it behoves every actuary to know at least the definitions and modus operandi of today's so-called renewal (point), or recurrent event, processes.
