揭开人事档案管理的神秘“面纱”

人事档案是记录和反映个人经历和德才表现等情况的文字材料,是组织人事部门历史地、全面地考察了解和选拔使用干部和员工的依据。人事档案管理就是组织人事部门(广义上的组织人事部门即国家党政机关、企事业单位、公司集团、群团组织中从事人力资源管理的部门或机构)按照一定规范,建立、整理、保管、使用人事档案的全过程,它在干部和员工的管理工作中发挥着重要的基础性服务作用。但是,长期以来传统封闭的管理模式给人事档案管理蒙上了一层“神秘面纱”,剥夺了档案相对人的档案信息知情权,阻碍了人事档案多方面作用的发挥。一长期以来,我国…

Chronology of the last six recessions

How successful have economists and other business forecasters been in predicting recessions? This question is of considerable practical value since the level of economic activity greatly influences budgets and other plans of businesses. The purpose of this paper is to examine forecasts of economic recessions that have been made over the last 20 years and evaluate the extent to which forecasters have been successful in their predictions. The approach used was to look closely at published forecasts in major business journals or specialized forecasting newsletters. The conclusion of the paper is that forecasters have been somewhat unsuccessful in their efforts to correctly predict the timing and depth of recessions. The implications of such a conclusion are that planners should not pursue the illusion that recessions can be accurately predicted and, instead, they should accept reality and shift the emphasis from attempting to forecast recessions to effectively monitoring the present state of the economy.     

Technology and society in the last quarter of the twentieth century

Critical times are approaching for technology and society. It will be a race between improving technology and worsening labour relations at a time when the depletion of natural resources will make itself felt. Unless far-sighted governments prepare in time for a gradual change, free enterprise and democracy will be in serious danger.     

The problem of the last bed: Contextualization and a new simulation framework for analyzing physician decisions

Faced with a full Intensive Care Unit (ICU), physicians need to decide between turning away a new patient in need of critical care and creating a vacancy by prematurely discharging a current occupant. This dilemma is widely discussed in the medical literature, where the influencing factors are identified, the patient discharge process described and the patient health consequences analyzed. Nevertheless, the existing mathematical models of ICU management practices overlook many of the factors considered by physicians in real-world triage decisions.This paper offers a review of the medical and mathematical literature on patient discharge decisions, and a proposal for a new simulation framework to enable more realistic mathematical modeling of the real-world patient discharge process. Our model includes a) the times at which discharge decisions are made and setup times for patient transfer from the ICU to a general ward and preparation of an ICU bed for an incoming patient, in order to capture the impossibility of an immediate switch of patients; b) advance notice of the number of patients due to arrive from elective surgery requiring intensive postoperative care and potentially triggering the need for early discharges to avoid surgery cancelations; and c) patient health status (to reflect the dependency of physicians’ discharge decisions on health indicators) by modeling length of stay with a phase-type distribution in which a medical meaning is assigned to each state.A simulation-based optimization method is also proposed as a means to obtain optimal discharge decisions as a function of the health status of current patients, the bed occupancy level and the number of planned arrivals from elective surgery over the following days. Optimal decisions should strike a balance between patient rejection and LoS reduction.This new simulation framework generates an optimal discharge policy, which closely resembles real decision-making under a cautious discharge policy, where the frequency of early discharge increases with the ICU occupancy level. This is a contrast with previous simulation models, which consider only the triage of the last bed, disregarding the pressures on physicians faced with high bed occupancy levels.     

基于两种策略的四级供应链质量控制优化研究

考虑到供应链实际构成与四级供应链质量控制研究不足,本文运用stackblerg博弈分析模型,研究了由供应商、制造商、经销商与消费者组成的四级供应链产品质量控制问题。在考虑需求不确定性的基础上,分析制造商与经销商之间延期支付和货款首付比例两种策略对供应链产品质量控制水平的影响,通过运用最优化原理求解制造商和供应商的最优质量控制水平并对结果进行仿真模拟,结果显示：制造商与经销商之间非质量协调策略对供应链产品质量有间接协调作用;制造商提高经销商货款首付比例或缩短余款延期支付时间,不仅有助于提高自身产品加工质量控制水平,更有助于供应商原材料质量水平提高,制造商在运用两种策略时,必须同时考虑产品价格引致的消费者需求量的变化和质量控制对其他主体收益变化的影响。

A practical model for last train rescheduling with train delay in urban railway transit networks

Last train timetable rescheduling aims at coordinating the arrival and departure times of feeder trains with connecting trains at transfer stations to eliminate the effect of unexpected incidents in train operations. It has become a challenging problem in the operations and management of urban railway transit networks because of high complexities in coordination among lines. In this paper, we propose a rescheduling model for last trains with the consideration of train delays caused by incidents that occurred in train operations. In the model, two aspects are considered. On one hand, we try to minimize the running time and the dwell time, and to maximize the average transfer redundant time and the network accessibility. On the other hand, we expect to minimize the difference between the original timetable and the rescheduled one. A genetic algorithm is developed to solve this problem. The case study of Beijing railway transit network shows that once a delay occurs in a section, the most effective way to adjust the timetable consists of adjusting the running time of trains that have strong transfer relationships with the delay section. If the delay is not substantially long, the suggested model would neutralize the influence of the delay.     

The game chromatic index of some trees with maximum degree four and adjacent degree-four vertices

A (proper) total-k-coloring of a graph G is a mapping \(\phi : V (G) \cup E(G)\mapsto \{1, 2, \ldots , k\}\) such that any two adjacent or incident elements in \(V (G) \cup E(G)\) receive different colors. Let C(v) denote the set of the color of a vertex v and the colors of all incident edges of v. An adjacent vertex distinguishing total-k-coloring of G is a total-k-coloring of G such that for each edge \(uv\in E(G)\), \(C(u)\ne C(v)\). We denote the smallest value k in such a coloring of G by \(\chi ^{\prime \prime }_{a}(G)\). It is known that \(\chi _{a}^{\prime \prime }(G)\le \Delta (G)+3\) for any planar graph with \(\Delta (G)\ge 10\). In this paper, we consider the list version of this coloring and show that if G is a planar graph with \(\Delta (G)\ge 11\), then \({ ch}_{a}^{\prime \prime }(G)\le \Delta (G)+3\), where \({ ch}^{\prime \prime }_a(G)\) is the adjacent vertex distinguishing total choosability.     

Implementation of S-DBR in four manufacturing SMEs: a research case study

Production planning and control systems (PPCs) are tools that have a major effect on the performance of manufacturing companies. An inappropriate determination of the applicability of PPCs could seriously jeopardise the ability to achieve competitive priorities. This mistake can be expensive for any company, but proper implementation is particularly critical for small and medium enterprises (SMEs), which are characterised by limited access to financial resources. Simplified Drum–Buffer–Rope (S-DBR) is a PPC control approach that is characterised by minimum detail in the planning stage and a primary emphasis on the control of execution. Therefore, this approach is a suitable choice for the highly variable context of SMEs. This study aims to explore the practical issues related to S-DBR implementation in four Ecuadorian SMEs through case study research. The case analysis within this study first identifies the choices made in the implementation process design within the four companies according to process and product characteristics. We then conduct a cross-case analysis to explore the effects of the S-DBR implementation process designs on a group of performance measures. Our research findings provide new insights into the S-DBR implementation process in the context of SMEs, and the effects of this approach on performance measures.
