The purpose of this paper is to propose a new measure for criticality analysis of different components of a production plant, called cost‐effective importance measure (CEIM) that considers the component's performance, system structure and economic aspects.

In this work, an explorative literature study covering the concept of importance measure and criticality analysis has been carried out on contemporary literature. The literature study shows that the commonly used importance measures consider the probability of failure of a component and systems structure, and ignore the effect or severity of failures, which is an important factor in engineering decision making. It is not clear how to use the concept of importance measure in combination with cost parameter. Hence, a cost‐effective importance measure (CEIM) is defined and a case study is presented, to demonstrate the application of the proposed importance measure.

The paper indicates that CEIM useful for the analysis of production plants where reliability and cost of break down are of paramount importance.

The concept of CEIM is demonstrated using only a case study of a belt conveyor system in the underground mine of Singareni Coal Company Ltd. However, the concept of CEIM can be used in other area.

The concept of CEIM can be a handy and effective tool for scheduling of inspection, maintenance and fault diagnosis and these activities can be carried out as per the rank of the components to maximize the benefits in skilled manpower crunch. It also indicates that the upgradation of the production plant's performance can also be done by improving performance of components with relatively large CEIM values.

In this paper, the concept of importance measure is extended to include the effect of severity of failures and cost parameter in the criticality analysis.

Communication of an impending hazard to people in near real time is critical. The purpose of this paper is to develop an internet‐SMS based geo‐hazard warning communication system.

A warning system based on an internet‐resident concept and the available cellular mobile infrastructure is proposed in this study. The functionality of the system is modular in architecture.

The messages have been transmitted in a set of 20 SMSs six times, to locally‐owned mobile numbers, resulting in a total number of 120. It has been found that 58 messages got delivered within ten seconds, the rest within 40 more seconds. The threat messages reached the impending threat areas within acceptable time delay.

The paper describes the implementation of a novel and stand‐alone system for dynamic hazard warning. Cellular or mobile phone, a gadget used by common man, is expected to be the best proposition to effectively warn people individually and to propagate hazard messages to users in large regions ubiquitously. The concept allows pervasiveness and redundancy, important to withstanding hazards and bringing several original elements through the development of this “fast warning system”, as current warning strategies do not include such solutions.

The authors aimed to examine the incarceration experiences of injecting drug users in accessing harm reduction, and HIV‐related services inside prisons in India.

The authors conducted three focus groups with a purposive sample of 23 formerly incarcerated male IDUs and four key informant interviews with a former police official, a drug dealer and service providers. Data were analyzed using a constant comparative method.

Participants reported availability of alcohol and injectable or oral drugs such as heroin, dextropropoxyphene, and marijuana inside prisons. Inmates obtained drugs and clean syringes (one syringe bought for 2.5‐4 USD) through prison staff, and collected used syringes and needles from the dustbins in prison sickrooms. Needles and syringes were reused and shared. Prisons did not have needle and syringe programmes, detoxification, overdose management or opioid substitution treatment. Drug‐using prison inmates faced several challenges in accessing antiretroviral treatment and HIV testing.

The authors' findings emphasize the need to protect the health of injection drug‐using inmates by introducing harm reduction programmes and removing barriers to HIV testing and antiretroviral treatment.

This study illustrates, for the first time, the contexts behind high risk injecting drug use behaviours among prison inmates in India. It also highlights the lack of availability of harm reduction services such as needle and syringe programmes, drug detoxification and opioid substitution treatment inside prisons. Further, it demonstrates the difficulties faced by HIV‐positive prison inmates in getting timely and uninterrupted antiretroviral treatment.

Status of fiscal health of local governments helps in determining planned budget and realistic action plan for citizens’ wellbeing. This paper aims to assess the fiscal health of local governments in Bangladesh.

Using data from 18 south-western municipalities of Bangladesh during the fiscal year 2018–19, this research measures fiscal health by applying Wang, Dennis and Tu’s solvency test and Brown’s Ten-Point Test.

The result shows that one-tenth of the entire municipalities are endowed with better position, whereas almost 39 percent of municipalities are in the worst situation and nearly 50 percent of municipalities are in the average category. Because of having limited liabilities, the municipalities are endowed with more than enough cash solvency and reasonable level of long-run solvency. The key problems are that budgetary solvency of all municipalities is not satisfactory, and service expenses are more than their revenue generation. This study suggests improving the financial capabilities of the municipalities through properly using their resources, generating loans, and claiming a need-based budget from the central government.

The paper investigates the status of fiscal solvency of local governments in Bangladesh in a new dimension. The findings might be helpful to policymakers in budgeting for development initiatives of local governments in Bangladesh so that citizens’ better wellbeing is ensured.
