Abstract

Purpose

The purpose of this paper is to report a numerical solution for the problem of steady, two dimensional boundary layer buoyant flow on a vertical magnetized surface, when both the viscosity and thermal conductivity are assumed to be temperature-dependent. In this case, the motion is governed by a coupled set of three nonlinear partial differential equations, which are solved numerically by using the finite difference method (FDM) by introducing the primitive variable formulation. Calculations of the coupled equations are performed to investigate the effects of the different governing parameters on the profiles of velocity, temperature and the transverse component of magnetic field. The effects of the thermal conductivity variation parameter, viscosity variation parameter, magnetic Prandtl number Pmr, magnetic force parameter S, mixed convection parameter Ri and the Prandtl number Pr on the flow structure and heat transfer characteristics are also examined.

Design/methodology/approach

FDM.

Findings

It is noted that when the Prandtl number Pr is sufficiently large, i.e. Pr=100, the buoyancy force that driven the fluid motion is decreased that decrease the momentum boundary layer and there is no change in thermal boundary layer is noticed. It is also noted that due to slow motion of the fluid the magnetic current generates which increase the magnetic boundary layer thickness at the surface. It is observed that the momentum boundary layer thickness is increased, thermal and magnetic field boundary layers are decreased with the increase of thermal conductivity variation parameter =100. The maximum boundary layer thickness is increased for =100 and there is no change seen in the case of thermal boundary layer thickness but magnetic field boundary layer is deceased. The momentum boundary layer thickness shoot quickly for =40 but is very smooth for =50.There is no change is seen for the case of thermal boundary layer and very clear decay for =40 is noted.

Originality/value

This work is original research work.

Abstract

Purpose

With the development of emerging engineering technology and industrialization, there are greater changes in the life style of people in smart urban cities; therefore, there is also more chance of various health problems in urban areas. The life style of persons in metro urban areas with the expansive volume of population is similarly influenced by different application and administration frameworks. These are affecting the human health system up to an extended extent and there are more health-related issues and health hazard concerns that can be identified in urban areas. The purpose of this paper is to present an analytical study on various aspects of the smart health care system in a smart perspective by analyzing them with respect to emerging engineering technologies such as mobile network, cloud computing, Internet of Things (IoT), big data analytics and ubiquitous computing. This paper also carries out a detailed survey of health issues and improved solutions in automated systems using these technologies. Second, the paper also presents a novel health care system using smart and safe ambulances and their appropriate control at traffic points with safety and security features in a smart city, so that the valuable life of patients can be saved in time by immediate treatment in nearest hospital or health care units.

Design/methodology/approach

In this paper, an analytical survey was conducted for improvement in the health care sector using computer technology and IoT-based various modern health care applications. An idea of Smart Health Care Hospital using sensors, mobile agent smart vehicle configuration and safety traffic control for ambulance was proposed.

Findings

A simulation was carried out to see the performance of a safety mechanism in the proposed approach. Comparative analysis was carried out with other approaches to know the execution time, response time and probable delay due to the implementation of this approach.

Originality/value

It is an original research work with motivation inspired from current emergent technology to apply in the health care system.

Abstract

Purpose

The purpose of this study is to address and analyse the current status of university library websites in Bangladesh. Particularly, it is focused on all universities accredited by the University Grants Commission (UGC) of Bangladesh. The purpose of this paper is to describe the marketing initiatives taken by university libraries to promote collection and services to their clientele.

Design/methodology/approach

For this study, university library websites were examined using a checklist of criteria developed from earlier studies and present websites. A total of 57 university library websites were examined and most of the websites were visited at least two times during the assessment, which started by checking the availability of direct and non-direct links from the home page of the parent institution followed by website assessment against the checklist. The paper also draws upon the authors’ personal experiences and observations.

Findings

The study identified that the websites are not fully utilized for marketing library resources and services, and that university libraries are not maximizing their promotional activities. A majority of libraries did not make any effort to provide online literacy courses, live support, copyright documents, online user surveys, networking, and so on.

Research limitations/implications

The study is limited to Bangladeshi university libraries and generalization to others is to be cautioned, but there are important lessons to be learned.

Practical implications

This paper will be helpful to libraries planning to implement a marketing strategic plan to improve outreach to users and enhance the image of the library.

Originality/value

The present study is new in Bangladesh and reveals several marketing strategies that may be useful to other academic libraries.

Abstract

Purpose

The study measures perceived service quality (PSQ) associated with user satisfaction of Dhaka University Library (DUL). To identify the service quality users’ needs and expectations were initially identified. Users’ perceptions of current services were also identified, from which current perceived service performance was identified.

Design/methodology/approach

A modified SERVQUAL instrument was used to survey DUL users. User responses for minimum, expected, and perceived services were calculated. A gap analysis was done to measure the PSQ that reveals two types of service gaps, i.e. positive gap provides quality services, and negative gap indicates the service shortfall. Users’ satisfaction level was also identified. In both cases (assessment of PSQ and satisfaction), “ME” (minimum service level) was used as common comparison standard.

Findings

The outcome of the study shows that “library hours” is the only service item which got the exclusive acceptance and ensured optimum satisfaction of the users, while other items fall short of meeting the user's need.

Research limitations/implications

The present study only identified different problematic areas of DU library services.

Originality/value

Very few attempts have been made to measure the service quality offered by Dhaka University library in Bangladesh. It is hoped that this study will trigger more research on understanding perceived service quality and satisfaction.

– The purpose of this paper is to measure students’ willingness to mentor their peers and explores key factors to student peer mentoring effectiveness.

Abstract

Purpose

The purpose of this paper is to measure students’ willingness to mentor their peers and explores key factors to student peer mentoring effectiveness.

Design/methodology/approach

The paper uses a hybrid research methodology consisting of a survey and a focus group discussion. The survey was conducted with students of a bachelor of commerce (BCom) program of a North American university to analyze the impact of organizational culture and altruism on their willingness to mentor their peers. The focus group discussion was carried out with students of the same program to explore the objectives, focus, and factors contributing to their willingness to mentor and to peer mentoring effectiveness.

Findings

Organizational culture and altruism significantly affect students’ emotional and intentional willingness to mentor their peers. Peer mentoring can help students prepare their transition from high school to university, guide them through university programs, and help them prepare their transition from university to workplace. Critical factors to peer mentoring effectiveness include a good fit between mentors and mentees, a reasonable ratio of mentor to protégés, and an understanding of and a willingness to address each student's specific needs.

Practical implications

Business schools should embrace and promote a culture of mutual help, look for altruistic students as prospective peer mentors, and promote voluntary student peer mentoring. A mentoring program should be flexible enough to meet each student's needs. Attention should be paid to finding a good fit between mentors and protégés. Communication should focus on the benefits of student peer mentoring for mentors and protégés.

Originality/value

This research brings empirical evidence on peer mentoring by testing and confirming the impact of altruism and organizational culture on students’ willingness to mentor their peers. It also provides practical insight to business schools for implementing student peer mentoring programs.

Abstract

Purpose

The purpose of this study is to explore the factors leading to the consumer's propensity to abandon the shopping cart at the transaction completion stage.

Design/methodology/approach

Data were collected using a self‐administered survey distributed through the internet. The sample consisted of consumers who shopped online at least once during the preceding one‐year period.

Findings

The results indicate that perceived transaction inconvenience is the major predictor of shopping cart abandonment. The other predictors are perceived risk and perceived waiting time. Positive relationship was found between perceived transaction inconvenience, perceived risk and propensity to abandon the shopping cart. It was also found that propensity to abandon the shopping cart is negatively associated with the perception of waiting time.

Practical implications

The paper provides transaction completion stage specific guidance to the managers operating in an online environment to prevent shopping cart abandonment at the transaction completion stage. Specifically, the findings suggest that marketers must pay attention to the perception of risk and transaction inconvenience; otherwise they risk losing consumers during the final stage of transaction.

Originality/value

The paper examines the unexplored area of consumer behavior at the final stages of transaction culmination and, hence, is an initial step toward filling that gap.

Abstract

Purpose

This study aims to present an effort to construct a measurement instrument to capture Islamic accountability from “accountability for what” aspect. These measurement instruments are developed by considering both social and economic natures in Islamic organisations.

Design/methodology/approach

This study defined the concept of Islamic accountability from the perspective of “accountability for what”. It is decomposed into specific items that suit an Islamic social enterprise (ISE). Next, these items are operationalised into scale items and re-composed empirically through factor analysis on data obtained from ISE stakeholders in Malaysia.

Findings

This study successfully developed an Islamic accountability measurement instruments from the “accountability for what” perspective for ISE. A total of 25 items are recognised and validated under four accountability dimensions, namely, accountability for input, accountability for output, accountability for procedural and accountability for Islamic principles and values.

Research limitations/implications

Not all measurement instruments are fit for every Islamic organisation type because of the different characteristics of Islamic organisations.

Practical implications

Developed items can be used as part of Islamic accountability index, especially by ISE and other similar organisations to measure their accountability practices. Besides, these developed items can also be adopted for reporting purposes. In the case of Malaysia, respective government agencies, such as the Companies Commission of Malaysia , the Registry of Society, the Ministry of Entrepreneur Development as well as the Malaysia Institute of Accountant, should have a look at the developed items to be considered into their respective guidelines or standards.

Originality/value

This study is believed to be a pioneering study in developing measurement instruments of Islamic accountability specific for ISE. It proposes measurement instruments of Islamic accountability that can be re-used for future research and is among the few studies of ISE.

Abstract

Purpose

This paper aims to concentrate on classifying and analyzing the risks associated with the Industry 4.0 (I4.0) concept in manufacturing industries and developing strategies for managing risks.

Design/methodology/approach

In this research paper, risks categories and their sub-components associated with the I4.0 concept are identified by performing a systematic literature survey of peer-reviewed journal articles and taking inputs from industry experts and academicians. Then, the importance of the identified risks and causal relations among risks are analyzed by using decision-making trial and evaluation laboratory (DEMATEL) method. Finally, the strategies are developed to mitigate the identified risks.

Findings

From the literature survey, 6 risk categories and their 19 sub-components associated with the I4.0 concept are identified. The DEMATEL method resulted in economic risks and technical risks as the top two risk categories in the I4.0 concept. Ecological risks and legal and political risks are relatively low-ranked risk categories.

Research limitations/implications

Causal relations and ranking among risk categories and their sub-components are obtained by analyzing responses received through questionnaires. There are other methods also available for risk analysis, which are beyond this study.

Practical implications

This research paper will help the industrialists to effectively manage the risks involved in adopting I4.0 concept in manufacturing industries by adopting strategies.

Originality/value

This research paper gives an idea about risks associated with the implementation of the I4.0 concept in manufacturing industries. Also, this paper uses the DEMATEL method for ranking the identified risk categories and their sub-components.

Abstract

Purpose

Industry 4.0 implementation appears to have a far-reaching effect on consumer demand. Research findings on market prospects and implementation status are also rare. The purpose of this study is to address the essential factors regarding the implementation status of the Indian manufacturing industries that would entail a complete implementation of the Industry 4.0 innovations in developing nations and execute them entirely to achieve related benefits.

Design/methodology/approach

The primary factors impacting the Industry 4.0 implementation status recognized a focus on comprehensive literature analysis and its validation by recommendations from 12 specialists with substantial expertise in Industry 4.0. The DEMATEL technique has been implemented in this analysis to examine the structure of causal interactions among the recognized essential factors.

Findings

From a literature analysis and recommendations from specialists, 16 essential factors are recognized. Using DEMATEL techniques, ranking of the essential factors has been obtained according to their importance. Moreover, the findings show the cause and effect interactions among essential factors in the perspective of Industry 4.0 innovations in Indian manufacturing industries.

Research limitations/implications

The current research is restricted to Indian manufacturing industries (developing nations).

Practical implications

It will help industries move towards an Industry 4.0 implementation by knowing their status. A research model is being developed, including specific vital features of Industry 4.0 as indicators for its implementation. Nevertheless, few are renowned for how industries, especially in developing nations, perceive the possible effects of Industry 4.0 technological innovations and industrial efficiency.

Originality/value

To the best of the authors’ knowledge, the present research contributes first to be carried out regarding the model of information about the nature of causal interactions among the recognized essential factors of Industry 4.0 in the surrounding of Indian manufacturing industries to address the implementation status of Industry 4.0 innovations using DEMATEL technique.
