The quality of work life (QWL), job satisfaction, and individual work performance are the lynchpins of organizational performance and sustained business growth (SBG). Numerous researchers have recognized an association between QWL and SBG. Positive QWL dimensions ensure a workforce's commitment to SBG. Like SERVQUAL, the QWL has several dimensions,...

Service quality is one of the most important factors behind customer satisfaction in commercial banks. Various studies revealed that service quality plays a decisive role in satisfaction of customers and satisfaction of customers to a great extent lead to the customer loyalty vis-a-vis profitability of banks. Against such a backdrop, an attempt has...

To keep information recent between two nodes, two types of link sensing feed-back mechanisms are used: link layer (LL) and network layer (NL). In this paper, we model and evaluate these link sensing mechanisms in three widely used reactive routing protocols: ad hoc on-demand distance vector (AODV), dynamic source routing (DSR), and dynamic MANET on...

In this paper, we propose a new Quality Link Metric (QLM), “Inverse Expected Transmission Count (InvETX),” in Optimized Link State Routing (OLSR) protocol. Then, we compare performance of three existing QLMs which are based on loss probability measurements: Expected Transmission Count (ETX), Minimum Delay (MD), and Minimum Loss (ML) in Static Wirel...

Wireless Body Area Networks (WBANs) are widely used for applications such as modern health-care systems, where wireless sensors (nodes) monitor the parameter(s) of interest. Nodes are provided with limited battery power and battery power is dependent on radio activity. MAC protocols play a key role in controlling the radio activity. Therefore, we p...

Wireless Mesh Networks is one of the most promising wireless technologies of the future. Its tolerance factor against the network failures, convenience of set-up and manageability are one of its major advantages. Though WMNs are very similar to ad hoc wireless networks, the architecture and protocols designed for ad hoc networks perform very poor w...

In this paper, we propose Energy-efficient Adaptive Scheme for Transmission (EAST) in WSNs. EAST is IEEE 802.15.4 standard compliant. In this approach, open-loop is used for temperature-aware link quality estimation and compensation. Whereas, closed-loop feedback helps to divide network into three logical regions to minimize overhead of control pac...

Preventive care service delivery faces immense challenges when it comes to the level of coverage. Within this context, the case of child immunization is presented by applying operations management tools. This paper explores the application of integer programming techniques to support the Expanded Programme of Immunization (EPI) service in the Dera...

Cluster based routing protocols forWireless Sensor Networks (WSNs) have been widely used for better performance in terms of energy efficiency. Efficient use of energy is challenging task of designing these protocols. Energy holes are created due to quickly drain the energy of a few nodes due to nonuniform node distribution in the network. Normally,...

Wireless Sensor Networks (WSNs) consist of large number of randomly deployed energy constrained sensor nodes. Sensor nodes have ability to sense and send sensed data to Base Station (BS). Sensing as well as transmitting data towards BS require high energy. In WSNs, saving energy and extending network lifetime are great challenges. Clustering is a k...

In past years there has been increasing interest in field of Wireless Sensor Networks (WSNs). One of the major issue of WSNs is development of energy efficient routing protocols. Clustering is an effective way to increase energy efficiency. Mostly, heterogenous protocols consider two or three energy level of nodes. In reality, heterogonous WSNs con...

In recent few yearsWireless Sensor Networks (WSNs) have seen an increased interest in various applications like border field security, disaster management and medical applications. So large number of sensor nodes are deployed for such applications, which can work autonomously. Due to small power batteries in WSNs, efficient utilization of battery p...

Social sector planning requires rational approaches where community needs are identified by referring to relative deprivation among localities and resources are allocated to address inequalities. Geographical information system (GIS) has been widely argued and used as a base for rational planning for equal resource allocation in social sectors arou...
Thesis
The aim of this thesis is to develop analytic methods to support the implementation of decentralization in primary health care. Decentralization may be defined as the delegation of decision-making power from central management to middle or local management for coordinated control. To be an effective mechanism for coordinated control it needs to be...
