基于单片机的病床呼叫系统设计与实现

医疗水平的不断提高,大部分医院都采用了病床呼叫设备,可这些设备基本都是有线设备无法移动,因而病人在离开病床后突发紧急情况时无法发出呼叫信号,而本文实现了基于单片机的无线病床呼叫系统的设计。该系统以STC89C51单片机为控制核心,无线发射模块首先发射呼叫信号,然后无线接收模块接收呼叫信号,经过STC89C51处理呼叫信号后显示呼叫病床号,实现病人与医护人员的无线沟通。

无卡手机难打救命电话

仅凭一格信号、一个停机的号码,身处险境的主角抓起一部连SIM卡都已损坏的手机,拨出关键的求救电话逃出生天……这是电影大片中烂俗的桥段,可在现实中,这一办法却常遭遇"掉链子"的尴尬。虽然手机的"紧急呼叫"功能已成国际公约,但记者亲测发现,在未插SIM卡的情况下,多数手机呼叫110、119、120时集体"哑火",根本无法拨通。专家受访时坦言,现行的行业标准或存疏漏,入网测试中其实并无硬性要求,加之诸多外围因素,导致"救命号码"成了空号。在国际公约中,紧急呼叫是指用手机拨打

Advanced workforce management for effective customer services

Because almost 60?C80% of the total costs for operating a contact centre involve wage and benefit expenses for personnel, determining the optimal number of agents available is of great importance in call centre management. In modern call centres, working hours are divided into planning intervals with identical lengths. Each planning interval is typically assumed to be a homogeneous Poisson process in a steady state, and simple queuing models, such as Erlang-C (M/M/c), are often applied to determine the optimal staffing levels of the planning intervals. However, since the actual length of the planning interval in practice is relatively short, the basic assumption of staffing analysis could be violated. In this paper, we numerically analyze an M/M/c+M call centre??s behavior in a transient state. As a result, we can determine appropriate staffing levels of a call centre with short planning intervals which do not assume to be in a steady state.

Human resource management in the Spanish call centre sector: the bird cage model of call centre work

This paper examines the nature of human resource management (HRM) in call centres in Spain. After reviewing the institutional perspective and other previous contributions to the characterisation of HRM practices in call centres, the authors present evidence of the use of high commitment working practices (HCWP) in this sector. The findings report only a moderate presence of HCWP in the sector generally, but the analysis points towards the existence of four significant and distinct clusters of HRM practices. The results also show categorical evidence that work discretion is almost non-existent across all of the clusters, even in those with more evolved high commitment practices. This lack of autonomy, as well as an intensive use of performance monitoring systems, leads us to model the results in a bird–cage analogy.     

Reducing burnout in call centers through HR practices

Previous research on call centers has demonstrated that human resource (HR) practices can be related to employee stress; however, these studies did not examine the linking mechanisms underlying these associations. Using the job demands–control (JD‐C) model as a theoretical framework, we examine perceived job demands (namely, emotional dissonance and quantitative demands) and autonomy as potential mediators in the relationship between HR systems and burnout (exhaustion and cynicism). We distinguish between HR control systems, which include performance monitoring practices, and HR involvement systems, which include training, participation, and performance‐related pay. This study samples 811 employees working in 11 call centers. Our findings support the idea that HR systems can help reduce burnout in call centers by verifying that HR control systems associated with more emotional dissonance and less autonomy increase burnout. On the other hand, an HR involvement system decreases workers' burnout because it alleviates the job demands of emotional dissonance and quantitative demands. This study fills a gap in the literature between HR systems and burnout by demonstrating the role job demands and autonomy play in explaining how HR systems improve or decrease workers' exhaustion and cynicism. © 2010 Wiley Periodicals, Inc.
