Abstract

The search for effective electronic resource sharing by libraries around the world is placed within a framework of commonly felt needs fomented by the digital age. The many forms such consortial undertakings have taken are described here. The existing challenges inherent in the consortial structure are also suggested.

Abstract

This paper discusses how libraries have and can address the digital divide through collection development. It provides specific examples of services and/or programs that have been implemented with this objective in mind. Since the term “digital divide” is often debated, a working definition is presented. The definition includes various components, each of which are discussed in relation to libraries. The paper also provides an overview of how collection development has changed in general through the emergence of digital technology. The importance of partnership among various institutions of society is stressed if the divide is to be properly addressed.

Abstract

Purpose

Oral health is an integral part of general health. Different population groups have been assessed for oral health status in India, but still, many have been neglected; one such group is the prisoners. The prison population is a unique and challenging one with many health problems, including poor oral health, which may be due to lack of knowledge about good oral health practices. This study aims to assess effectiveness of oral health education on oral health knowledge, attitude and practices and oral hygiene status among the male prison inmates of central jail in Kolkata, India.

Design/methodology/approach

An interventional study was done among 240 male convicts. The data was elicited using a structured proforma; oral health status was assessed by recording OHI-S index, and the severity of gingivitis was assessed by recording the gingival index. Oral health education was delivered by using audio-visual aid. Oral health knowledge, attitude, practices and oral hygiene and gingival status were reassessed among the inmates before and after dental education at the end of three and six months.

Findings

A significant change in oral health knowledge, attitude and practices was seen, which in turn resulted in an appreciable decrease in the mean gingival index score (1.73 ± 0.382 to 1.20 ± 0.321) and OHI-S (3.31 ± 0.815 to 2.57 ± 0.551) in all the inmates after oral health education program over the period of time.

Originality/value

The oral health education with reinforcement proved to be an effective tool to instil good oral hygiene practices in the inmates.

Abstract

Purpose

This paper examines the time-varying efficiency of nine major Middle East and North Africa (MENA) stock markets namely Egypt, Bahrain, UAE, Jordan, Saudi Arabia, Oman, Qatar, Morocco and Tunisia during times of COVID-19 pandemic outbreak and vaccines.

Design/methodology/approach

The authors use two econometric approaches: (1) autocorrelation tests including the wild bootstrap automatic variance ratio test, the automatic portmanteau test and the Generalized spectral test, and (2) a non-Bayesian generalized least squares-based time-varying model with statistical inferences.

Findings

The results show that the degree of stock market efficiency of Egyptian, Bahraini, Saudi, Moroccan and Tunisian stock markets is influenced by the COVID-19 pandemic crisis. Furthermore, the authors find a tendency toward efficiency in most of the MENA markets after the announcement of the COVID-19's vaccine approval. Finally, the Jordanian, Omani, Qatari and UAE stock markets remain globally efficient during the three sub-periods of the COVID-19 pandemic outbreak.

Originality/value

The results have important implications for asset allocations and financial risk management. Portfolio managers may maximize the benefit of arbitrage opportunities by taking strategic long and short positions in these markets during downward trend periods. Policymakers should implement the action plans and reforms to protect the stock markets from global shocks and ensure the stability of the stock markets.

Abstract

Purpose

This paper aims to advance the squeeze film characteristics of long partial journal bearings with couple stress fluid studied by Lin to include the effect of permeability on the squeeze film lubrication of long partial porous journal bearings with couple stress fluids.

Design/methodology/approach

A semi‐analytical and semi‐numerical solution for the squeeze film lubrication of long porous partial journal bearings lubricated with couple stress fluid is presented in the paper. The modified Reynolds equation governing the fluid film pressure is derived. The modified Reynolds equation is solved analytically and closed form expressions for the squeeze film pressure and load carrying capacity are presented. The first‐order non‐linear equation for the time‐height relation is solved numerically with the given initial condition. The effect of couple stresses and permeability on the squeeze film characteristics are discussed.

Findings

It is found that the effect of couple stresses is to increase the load carrying capacity and to lengthen the squeeze film time as compared to the corresponding Newtonian case. The effect of permeability is to reduce the load carrying capacity and to decrease the squeeze film time as compared to the corresponding solid case.

Originality/value

In the design of porous partial journal bearings, the reduction in the load carrying capacity and the response time can be compensated by the use of lubricants with proper microstructures by which the bearing life can be increased.

Abstract

Purpose

To study the combined effects of permeability and couplestresses on the performance characteristics of a secant‐shaped porous slider bearing lubricated with Stokes couplestress fluid.

Design/methodology/approach

The modified Reynolds type equation governing the fluid film pressure is derived on the basis of Stokes microcontinuum theory of couplestress fluids by using Beavers‐Joshep slip boundary conditions at the fluid‐porous interface. The modified Reynolds equation is solved analytically and closed form expressions are obtained for the fluid film pressure, load carrying capacity, frictional force and centre of pressure.

Findings

The bearing characteristics are computed for various values of the couple stress parameter, slip parameter and the permeability parameters. It is found that, the effect of couple stress is to increase the load carrying capacity and to decrease the coefficient of friction as compared to the Newtonian case. However, the effect of permeability parameter is to decrease the load carrying capacity. It is also found that, the effect of couple stresses is to shift the center of pressure towards the outlet edge.

Research limitations/implications

The end effects are neglected in the analysis and these can be included in the study by considering full three‐dimensional problem.

Practical implications

Reduction in the load carrying capacity due to the presence of porous facing can be compensated by the use of lubricants containing additives of proper size. As a result the bearing performance can be improved.

Originality/value

This paper provides closed form expressions for the bearing characteristics and are analyzed with respect to non‐dimensional parameters, viz. couplestress parameter, slip parameter and permeability parameter. This paper offers help to design engineers to design efficient bearing systems.
