Abstract

Purpose

The purpose of this paper is to investigate computer literacy competencies among rural and urban students in India and its prime objectives are to find out: how rural and urban students use computers, what is the purpose of computers for these students and what problems have the students encountered while using computers.

Design/methodology/approach

Scheduled interviews were conducted to collect necessary data from rural and urban students. The interview schedules consisted of various questions designed to elicit details about the students’ use of computers. A total of 600 interview schedules were collected and data were analyzed using Statistical Package for the Social Sciences for windows to test the formulated hypothesis.

Findings

The findings of the study indicate that the infrastructural facilities varied among rural and urban schools. Another notable finding of the study was that majority (91.33 percent) of urban students used computers compared to a significantly less percentage of rural students (32.33 percent). Most rural students have not used computers mainly because they do not know how to (49.75 percent) followed by lack of support from teachers (48.76 percent) and non-availability of computers in their schools (48.27 percent). Electrical power failure was another major problem faced by both urban students (31.75 percent) and rural students (40.20 percent).

Originality/value

This study attempted to learn about the computer literacy competencies among the students and the digital divide in Indian schools. On the basis of the findings, the study has recommended guidelines to bridge the digital gap. These findings and recommendations will potentially be helpful to school authorities and the government in order to take the necessary measurements to bridge the digital gap between the rural and urban students.

Abstract

Purpose

This study aims to understand the expectations of rural students with respect to their computer access and use. It also made an attempt to learn the expectations of rural students from their schools and local government in providing the information and communication technology (ICT) infrastructure.

Design/methodology/approach

Interview schedules were used to collect the necessary data from the rural students. The interview schedules consisted of various questions that were designed to elicit the expectations of rural students in terms of their usage of computers. A total of 300 interview schedules were collected from the students, and data were analyzed using Statistical Package for the Social Sciences (Windows 19.0 version) to test the formulated hypothesis.

Findings

This study clearly showed that 72 per cent of female and 63.33 per cent of male students have not used a computer. Most of the students opined that lack of support from teachers (91.57 per cent = Male, 94.25 per cent = Female) and non-availability of computers at home and schools (82.10 per cent = Male, 80.55 per cent = Female) were the main reasons for not using the computer. A notable finding of the study was that 93.68 per cent of male and 95.37 per cent of female students were interested in using a computer. Most of the students opined that the state/local government should establish computer laboratories and provide Internet facilities in rural schools.

Originality/value

This paper has provided useful empirical data regarding the expectations of rural students with respect to their access and use of computers. The results of this study will be more helpful to school authority and government in providing necessary ICT infrastructure to rural schools.

Abstract

Purpose

The purpose of this paper is to know the frequency, place, and purpose of use of computer. It also aimed to know the various problems faced by the students in using the computer and to know the reasons for not using computer by rural and urban students.

Design/methodology/approach

A total of the 2,592 sample population were selected from 64 rural and urban high schools of two districts of Karnataka state. A structured questionnaire was used for the data collection and data have been analyzed using Software Package for Social Science. Statistical tests, namely, χ2 and one-way ANOVA were applied to test the formulated hypotheses.

Findings

The results of the study showed that only 20.66 percent rural students and 69.70 percent of urban students used computer for various academic purposes. Further, most of the rural and urban students opined that “electric power failure” and “lack of computer” skills were major problem in using computer.

Originality/value

Today, the computer education in schools plays an important role in student’s career development and enhances the quality of learning among students. Thus, the local government/school authorities may provide the minimum ICT infrastructure in both schools and more particularly in rural schools.

Abstract

Purpose

The purpose of this paper is to examine the critical factors that drive the adoption of digital library system (DLS) in institutes located in remote India. An integrated model of the unified theory of acceptance and use of technology model-2 (UTAUT2) and information systems success model (ISSM) is used to evaluate the critical factors.

Design/methodology/approach

The survey method of research was used, and the data collected was analysed by using PLS-SEM, which proved helpful to evaluate and validate the model.

Findings

Departing from past research, where most of the factors of the UTAUT2 and ISSM were found to influence the adoption of DLS, in this context, it is noted that performance expectancy, facilitating conditions and habit were the only constructs that influenced the intention to use DLS.

Originality/value

The study addresses the requirement for further research in DLS domain in emerging markets. It is one of the few studies addressing DLS adoption in remote India. The findings are unique to this context, which differ from developed nations, thus, answering the call to advance UTAUT model.

Abstract

Purpose

In the digital era, the dynamics of the communication process in classrooms have changed significantly. With the help of computer-mediated communication techniques, especially animation, teachers can deliver a distinct learning experience to students that can be fun, while presenting complex ideas in simpler forms. The purpose of this paper is to assess the effectiveness of animation in education, in the context of developing Asian countries, using Karnataka, an Indian state, as a study area.

Design/methodology/approach

This paper uses the field experimental method to assess animation’s effectiveness in education. Attempts are made to neutralize the influence of extraneous factors, such as psychological conditions, and the socio-economic background of students, while assessing academic performance. To achieve this, a fuzzy-set-theory-based two-sample statistical hypothesis test is used.

Findings

Results indicate that animation can be used as an effective tool for communication in pedagogy and, if used properly, can improve students’ academic performance in primary education, even in developing countries such as India.

Research limitations/implications

The paper’s limitations are explored, and point to how future research could use more advanced statistical tools to identify the motivational, behavioral, cognitive and psychological factors influencing students, when animation is used in education, and should perform a comparative analysis of the performance of students in developed and developing countries.

Originality/value

As the current study proves that animation is effective in education, even in developing countries such as India, efforts should be made to convert existing curricula into animated multimedia content. Currently, most government-run schools in India use traditional chalk-and-talk methods for teaching. The use of animated instructional material will help improve the standard of educational communication in classroom, and maintain consistency in delivering the curriculum.

Abstract

Purpose

This study firstly aims to prepare a hierarchical structure of the barriers contributing to digital exclusion of women. Secondly, the study aims to understand the inter-relationship of the barriers by converting them into a cyclic flow.

Design/methodology/approach

Systematic review was conducted through Web of Science and EBSCO Host Discovery Services with keywords: “digital divide” OR “digital gap” OR “digital inequality” OR “online difference” AND gender AND wom?n AND factors OR “demographic factors” OR “socio-economic” OR determinants OR reasons OR causes OR influences. Review was conducted of articles published in English language after 2012. Systematic literature review was conducted in line with Preferred Reporting Items for Systematic Reviews and Meta-Analyses Framework 2020. Authors reviewed 21 reports.

Findings

This research found absence of education as the root of digital exclusion of women in the hierarchy of barriers. The cyclic flow of barriers displayed that how ill education of women lead to financial and psychological dependence of women on men, creating a hurdle in women empowerment. To break the cycle of digital exclusion, women education is must not only on primary basis but their tertiary education is important too.

Originality/value

This study makes an important contribution by ranking those barriers in a pyramid hierarchy and depicting their inter relation by framing a cyclic structure. This study provides suggestions to remove those barriers and ultimately break their chain to provide digital inclusive society for women.

Abstract

Purpose

In the present scenario of high-speed machines, the use of non-circular hole-entry bearing configuration, i.e. two-lobe, multi-lobe, lemon bore, etc., has becomes unavoidable, as the journal bearings with non-circular configurations provide better stability at high operating speed and heavy dynamic loading. Further, this research aims to show that the presence of micro particles in the lubricants greatly affects performance of the bearings, as their presence leads to non-Newtonian behaviors of the lubricant. Therefore, to consider the effect of these micro particles, the lubricant is modeled as a micropolar lubricant. The present work analyzes the effect of these micropolar lubricants on the performance of hole-entry circular and non-circular (two-lobe) hybrid journal bearings compensated with constant flow valve restrictor and compares with that of Newtonian lubricants.

Design/methodology/approach

The modified Reynolds equation governing the laminar flow of iso-viscous, incompressible micropolar lubricant in the clearance space of a journal bearing system has been solved using finite element method and appropriate boundary conditions. Further, a comparative analysis between circular and non-circular (two-lobe) hybrid journal bearing compensated with constant flow valve restrictor operating with Newtonian and micropolar lubricant has been presented.

Findings

The numerically simulated results reveal that the non-circular bearing configuration provides better performance vis-à-vis the circular bearing configuration. Further, the increase in the micropolar effect of the lubricant enhances the performance of circular and the non-circular bearing configurations compared with the Newtonian lubricant. Also, in the case of the non-circular bearing configuration with an offset factor (δ = 1.5), the bearing performance improved compared with (δ = 1.25).

Originality/value

Many research studies have been done in the area of non-circular hybrid journal bearing with Newtonian lubricants with different types of restrictors, but the non-circular hole-entry constant flow valve-compensated hybrid journal bearing operating with the micropolar lubricant has not been analyzed. Therefore, in the present work, an effort has been made to fill this research gap.

Abstract

Purpose

The non‐recessed hybrid journal bearings of cylindrical type, when operating at higher rotational speeds can suffer self‐exited vibrations(oil‐whirl Instability), which can cause excessive rotor motion causing bearing and sometimes total machine failure. The multi‐lobe journal bearing exhibits better stability as well as a superior capability to suppress oil‐whirl. The paper aims to present a theoretical study pertaining to a two‐lobe hole‐entry hybrid journal bearing by considering the combined influence of surface roughness and journal misalignment on the performance of the bearing.

Design/methodology/approach

The average Reynolds equation governing the flow of lubricant in the clearance space between the rough bearing surfaces together with the equation of flow through a capillary restrictor has been solved using FEM. The bearing performance characteristics have been simulated for a two‐lobe hole‐entry hybrid journal bearing for the various values of offset factor, restrictor design parameter, surface roughness parameter, surface pattern parameter and journal misalignment parameters.

Findings

The two‐lobe hole‐entry hybrid journal bearing system with an offset factor greater than one indicates significant improvement of the order of 15‐25 percent in the values of direct stiffness and direct damping coefficients compared to a circular hole‐entry hybrid journal bearing system. Also the lubricant flow of a two‐lobe hole‐entry hybrid journal bearing is reduced by 25 percent vis‐à‐vis circular bearing.

Originality/value

The present work is original of its kind, in case of two‐lobe hole‐entry hybrid journal bearing. The results are quite useful for the bearing designer.

Abstract

Purpose

The current trend of modern industry is to use machineries which rotate at high speed along with the capability of carrying heavy rotor loads. This paper aims at static thermal analysis of two different profiles of non-circular journal bearings – a true elliptical bearing and orthogonal bearing.

Design/methodology/approach

The Reynolds equation has been solved through finite difference method to compute the oil film pressure. Parabolic temperature profile approximation technique has been used to solve the energy equation and thus used for computation of various bearing performance characteristics such as thermo-hydrodynamic oil film pressure, temperature, load capacity, Sommerfeld number and power loss characteristics across the bearing. The effect of ellipticity ratio on the bearing performance characteristics has also been obtained for both the elliptical and vertical offset bearing using three different commercially available grades of oil (Hydrol 32, 68 and 100).

Findings

It has been observed that the thermo-hydrodynamic pressure and temperature rise of the oil film is less in orthogonal bearing as compared to the true elliptical bearing for same operating conditions. The effect of ellipticity ratio of non-circularity on bearing performance parameters have been observed to be less in case of elliptical bearing as compared to orthogonal bearing. It has been concluded that though the rise in oil film temperature is high for true elliptical bearing, but still it should be preferred over orthogonal profile under study, as it has comparably good load-carrying capacity.

Originality/value

The performance parametric analysis will help the designers to select such kind of non-circular journal bearing for various applications.
