高校学生党员质量控制问题

高校一些大学生要求思想政治进步,积极靠近党组织,志愿加入中国共产党,成为一名光荣的中共党员。由于大学生是一个特殊的青年群体,为党内输入新鲜血液而增加党的生机与活力,对于完成伟大的社会主义事业和共产主义事业的意义是不可估量的。但是,在确定他们入党、准予入党和入党后始终能够达到一个党员的标准,在工作中先锋模范、努力拼搏、无私奉献,关键的是他们有很强的党员意识、很高的思想政治觉悟。为此,提出学生党员质量控制和如何控制的问题,从入党前注重对入党积极分子的培养、入党中严格入党条件和程序、入党后追踪培养与严格管理三个相互联系的过程中提出质量控制问题。

Burnout and impaired cognitive functioning: The role of executive control in the performance of cognitive tasks

Abstract

Burnout patients often report deficits in cognitive control, and there is a need to understand the processes involved. Drawing on recent findings, we hypothesized that emotional exhaustion and task-related demands on executive control would interact in predicting performance in tasks requiring the updating and monitoring of working memory as well as the inhibition of prepotent (dominant or automatic) responses. In accordance with recent conceptualizations of burnout, we focused on emotional exhaustion as the core symptom of burnout. The sample comprised 81 employees recruited from nursing homes for elderly care in Germany, who participated in a laboratory study involving cognitive tasks. Based on a median split, participants were divided into two groups: those with high burnout and those with low burnout. In line with our hypotheses, the high exhaustion participants performed less well than those with low exhaustion only when tasks put high demands on their executive control. As predicted, high levels of emotional exhaustion were associated with more errors and longer reaction times when demands on executive control were high, whereas no performance differences were found when both tasks put low demands on executive control. The implications for practice are discussed.     

An EOQ model with partial delayed payment and partial backordering

In many transactions concerning selling and buying, a specified delay of payment is offered or accepted by the seller. This can be regarded as a kind of discount and has potential consequences for the order size. These kinds of effects are not explicitly incorporated in the classical formulas for economic order quantities (EOQ). In this research we consider an EOQ problem under partial delayed payment. A fraction of the purchasing cost must be paid at the beginning of the period and the remaining amount can be paid later. Shortages are permitted and occur as a combination of backorders and lost sales. The aim of this paper is to determine the order and shortage quantities.     

The effect of objective job demands on registered sickness absence spells; do personal,social and job-related resources act as moderators?

Abstract

This study applied Karaseks demand-control model, using sense of coherence (SOC), social support and job control as moderators of effects of job demands on ensuing sickness absence spells in a 3-year follow-up of 856 municipal employees. Among men the results supported the active learning hypothesis. Passive jobs predicted a high number of sickness absence spells and active jobs predicted a low number of spells. for short spells (1-3 days), the demand-control interaction, however, depended on SOC. In active jobs SOC was negatively associated with sickness absence spells; in passive jobs no such association was found. For long spells (3 days), the demand-control interaction depended on occupational level; active jobs were predictive of low absence spells among blue collar men. Among women, the results supported the strain hypothesis. The demand-control interaction, however, depended on household size. In small households, high-strain jobs predicted a high number of spells, while no increase in spells was found in active versus low-strain jobs. In larger households, the number of spells correlated positively with increasing demands even when control was good. The demand-control interaction, however, depended on SOC and spouse support. With strong SOC or spouse support, absence spells in active jobs remained on a relatively low level, otherwise active jobs led to a high number of spells. This suggests that SOC and spouse support may act as protective factors against female role conflicts associated with active jobs     

A routine-based framework implementing workload control to address recurring disturbances

Abstract

This research focuses on responsiveness in high variety manufacturing environments. To achieve it, the article proposes to develop Dynamic Response Capabilities (DRCs) of the manufacturing system defined as the abilities to readjust the planned operating parameters of workload, capacity, and lead time, in the wake of disturbances. To inform their development, built on the Workload Control theory, a routine-based framework is proposed. The framework supports an integrated approach for the implementation of adaptive decision-making routines for workload, capacity, and lead time readjustments at different stages in the order fulfilment process. Findings from two empirical cases show the appropriateness of the framework to develop and utilise DRCs in different settings of disturbances. Results of a simulation study, with one of the case companies, also shows the effectiveness of the framework to drive performance improvements in presence of recurring disturbances leading to demand variability.     

Judicious order acceptance and order release in make-to-order manufacturing systems

This paper explores a two-stage input control system for fixed capacity make-to-order manufacturing systems (with heavy job tardiness penalties), that selectively accepts incoming orders and holds the accepted ones in a pre-shop queue prior to releasing them to the shop floor. Single-stage input control systems that only allow orders to be delayed in a pre-shop queue (i.e. they do not allow some orders to be rejected) have been previously investigated and found to negatively impact overall due-date performance. The hypothesis motivating this research is that judiciously rejecting a subset of incoming orders can prevent the order release queue from being overloaded when a surge of demand occurs. The input control system is evaluated via experiments using a discrete-event simulation model of a fixed capacity manufacturing system. The experiments reported here suggest that holding orders in the pre-shop queue does not improve due date performance, and that judiciously rejecting orders on its own is a viable alternative mechanism of input control that can deliver improved performance.     

Shop floor characteristics influencing the use of advanced planning and scheduling systems

The purpose of this article is to investigate how the manufacturing process, the shop type and the data quality, i.e. the shop floor characteristics, influence the use of advanced planning and scheduling (APS) systems in production activity and control (PAC). The methodology implemented is a multiple case study at three case companies. Each company has different shop floor characteristics, but all use a scheduling module in an APS system, which supports production scheduling. A theoretical framework is developed suggesting how APS system are used in the PAC activities, and which major aspect to consider. The case analysis shows that the scheduling module in APS system, foremost supports sequencing and dispatching. In particular, the shop type is influenced by the decision of how often the APS runs and what freedom is given to the shop floor. The manufacturing process influences how the dispatch list is created. Contrary to the literature presuming that APS systems are most suitable in job shop processes, it is found that the manufacturing process is not a crucial factor when deciding whether APS systems are an appropriate investment. It is found that the level of data quality needed in the APS system depends to a large extent on how the dispatch list is used. For example, is the dispatch list used as a guideline, not a regulation, the need for accurate data in the module is reduced. This article extends the previous literature concerning APS systems by analysing how APS systems influence PAC as a whole and increase the understanding of the challenges of using APS systems in PAC.     

考虑奖惩机制和成本互担的众包物流服务质量最优控制

研究动态视角下服务平台和接包方如何控制众包物流服务质量的问题。引入众包物流服务质量标准,考虑奖惩机制和成本互担契约,构建了众包物流服务质量控制的微分博弈模型,利用庞特里亚金极大值原理求解出双方的最优质量控制水平、利润以及众包物流服务质量和需求随时间变化的最优轨迹。研究表明：服务价格在集中、分散和成本互担三种决策情形的物流服务过程中都保持不变;成本互担契约情形下,通过控制成本互担比例,服务质量、需求和总利润均能达到集中式情形的最优值,而且当奖惩因子满足一定条件时,双方利润相较于分散式情形都能得到改善;奖惩因子和佣金率的提高会增加接包方提升质量控制水平的积极性,但服务平台出于节约成本的目的会降低自身的质量控制水平,而仅依赖接包方较高的质量控制水平提高物流服务质量;当众包物流服务质量标准超过一定值时,奖惩因子的提高会造成服务平台利润的增加,接包方利润的减少。     

Locus of control and saving: The role of saving motives

Using data from a longitudinal survey representative of the Dutch population, we analyze the relationship between saving and locus of control, and we study the underlying mechanisms. Locus of control measures the extent to which individuals perceive their life outcomes to be determined by their own actions, as opposed to external factors. Those who believe to be in control of future outcomes turn out to save more, both at the extensive (decision to save) and intensive margins (amount saved). We investigate the mechanisms behind this relationship. We implement a mediation analysis to examine the role of saving motives, distinguishing between specific and non-specific purposes. The effect of external locus of control is direct, while the effect of internal locus of control is indirect, largely driven by (non-specific) saving motives.
