Abstract

Purpose

The purpose of this research paper is to optimize the process parameters of selective laser sintering process, and the sintered parts of PA2200 prototypes are built with minimum surface roughness within the range of 10-12 microns using the Taguchi design of experiments approach.

Design/methodology/approach

In this research paper, a 3D model is created using catia V5 and exported to rapid prototype machine, and the 3D model file was repaired by using Magics software to remove the facets and saved with file extension .stl (standard triangulation language).Taguchi design of experiments approach L9 orthogonal array was selected with three factors at three levels each and total nine experiments were conducted with the quality index lower-the-better signal-to-noise ratio to produced better quality prototypes by optimizing the process parameters like laser power, layer thickness and temperature and tested on surface tester for surface roughness. The experimental results of surface roughness were compared with Regression Analysis, S/N Ratio, Analysis of Mean and predicted model on sintered prototypes.

Findings

The experimental results obtained after testing on the surface tester compared with mathematical model for the quality index lower-the-better signal-noise ratio with optimal process parameters operating at Temperature at level 3, Layer thickness at level 3, and Laser power at level 3, regression analysis, and predictive model the output response variable surface roughness, is with in the range of 9-10.5 microns are all most same and from ANOM (Analysis of Mean), temperature at leve1, layer thickness at level 2, laser power at level 2 is 9 -9.6 microns.

Research limitations/implications

The process parameters such as beam diameter and table speed were not considered on output response variable surface roughness in this research paper.

Originality/value

All the experiments were conducted and the parts are produced by using the material PA2200 in the powder from and sintered by Co2 laser by varying the process parameters with optimal settings to produce minimum surface roughness the out put from this paper is the influence of process parameters on surface roughness can be predicted at optimal settings with in less time and cost.

Abstract

Purpose

This study aims to design a proposed framework for evaluating university websites.

Design/methodology/approach

This study is an exploratory mixed research. It was an applied research in terms of objective and used the Delphi technique and systematic review and meta-analysis approaches. Data collection tools were done through library studies, Delphi checklist and observation. The statistical population of the research comprised 17 experts who are designers of university websites and 20 Iranian university websites selected from the Webometrics website. The statistical data were analyzed using fuzzy methods, descriptive and inferential statistical methods and the SWARA weighting method. Also, the statistical analysis software SPSS 20 and Excel 2016, TOPSIS engineering software and MAXQDA were used.

Findings

Findings indicated that the dimensions of the designed proposed framework in order of their weights are credibility (0.130), reliability (0.125), usability (0.120), website design (0.110), functionality (0.104), content (0.100), page design (0.0922), efficiency (0.082), Webometrics (0.070) and systematic evaluation (0.067). Mebrate’s (2010) framework had the highest overlap (mean = 74.65), and Webometrics (mean = 18.5) had the least overlap and dependency (mean = 19) with the proposed framework. In the evaluation of the 20 university websites of Iran selected from the Webometrics site, the University of Tehran was ranked first with a score of 82.7 and Shiraz University was ranked last with a score of 75.

Originality/value

This study provides a comprehensive proposed framework for evaluating university websites that eliminates the shortcomings of all models, frameworks and methods of university website evaluation that focused only on one or more dimensions of university websites.

Abstract

Purpose

This research aims to compare the preference of social media sites and institutional communication channels of a higher education institution by confronting elements that form perceived usefulness and user satisfaction with the system. Social media technologies are a part of the routine of the modern society in many diverse ways, including the support and even substitution of software designed specifically for knowledge acquisition and sharing. If students do not see value in the use of virtual learning environments and learning platforms, such tools might be prone to obsolescence as well.

Design/methodology/approach

The study was applied in a Brazilian public university located in a major city near São Paulo. The paper shows the results of the analysis of a survey with 108 answers, testing a model based on the information system success and on the technology acceptance model. The perceived usefulness of information technology is also subject to test through a Student t-test.

Findings

The paper shows that students perceive more value when using social media technologies to perform academic activities than in information systems provided by the university, mainly owing to the ease of use of the former. Service quality does not present a strong role as an antecedent variable in any case.

Practical implications

Students do not expect or do not see value in technical support during their general experience or usefulness for any of the analysed technologies. Thus, higher education institutions should focus their initiatives in providing availability, information quality and usability for institutional channels or, if they choose to do so, social media sites as well.

Originality/value

This study contributes to educational institutions by attaining better use of available IT tools for academic purposes. Previous studies looked for monitored or institutionalized use of social media tools in an educational context, but there was no in-depth analysis of spontaneous use by students to perform academic tasks.

Abstract

Purpose

The purpose of this paper is to statistically explore the relationship between web usability and web presence of the universities. As a case study, five Turkish universities in different rankings which were selected from Webometrics rankings were evaluated and compared.

Design/methodology/approach

Two different methods were employed for performing usability evaluation of the selected universities: a user testing was used to measure the user performance on the selected tasks and a questionnaire to assess the user satisfaction on the website use. Both usability evaluation methods were applied on the pre-determined tasks for each university by participation of 20 subjects. After the usability evaluation, the universities were ranked in terms of usability results and finally, the relationship between web usability and web presence of universities was statistically investigated by using Kendall’s rank correlation.

Findings

Several common usability problems which were asserted by related previous studies were identified at the end of usability evaluation of university websites. The usability results also revealed that selected Turkish university websites suffer from numerous usability problems. Further, a strong positive correlation (p < 0.05) between the usability of the university websites and their web presences were identified. Hence, the participants showed a higher success and satisfaction while performing the tasks on the university websites which have strong web presences.

Practical implications

The findings from this study have practical implications for universities. Correlation results showed that universities can improve their web usability by giving importance to their web presence volumes. Universities can estimate their web usability levels by investigating their web presence rankings and they can also raise their rankings in Webometrics ranking system by improving the usability of their websites. Moreover, university web developers can design more usable and more user-friendly websites by avoiding usability and design problems identified through usability evaluation.

Originality/value

Different from the prior research efforts focussing on usability of educational web pages, this study contributes to the growing literature by statistically exploring the relationship between web presence and web usability of universities. This study is also precious from the point of view that it is one of the first attempts to evaluate and compare usability levels of a set of universities’ websites from Turkey.

Abstract

Purpose

Leadership has a decisive role in the success of all types of businesses and firms, including small- and medium-sized enterprises (SMEs), and the ethical behavior of leaders is a key component which brings a sense of respect, fulfillment, trustworthiness and acceptance among the employees, which later become visible in their job performance (JP). This study aims to check the immediate effect of ethical leadership (EL) on employee’s JP (EJP) and also explore the indirect mediating effect of corporate social responsibility (CSR) on this EL and EJP nexus.

Design/methodology/approach

Primary data was obtained from the employees of manufacturing SMEs of Northern Italy using a cross-sectional design from the end of 2019 to the start of 2020. This paper circulated 450 self-administered questionnaires using simple random sampling, and 202 (44.88%) valid questionnaires were returned. The PROCESS macro was performed using statistical package for social sciences to ensure whether or not EL affects EJP and is there any mediation effect of CSR present in this nexus.

Findings

The results indicate that EL has a strong positive connection with EJP and CSR. Interestingly, CSR positively influences EJP. Furthermore, the results also report the strong mediating effect of CSR in the nexus of EL and EJP.

Originality/value

This scholarly work seeks to contribute not only to the literature of EL and EJP but also enriches the understanding of this EL-EJP association by highlighting the indirect effect of mediating variable CSR in the SME sector.

Abstract

Purpose

This paper investigates the mediating role of access to finance and entrepreneurial education for small and marginal farmers (SMFs) in the Indian northern state of Punjab. Furthermore, it examines the inter-mediatory role of entrepreneurs and the access to finance in the promotion of innovation, development and consequently poverty alleviation.

Design/methodology/approach

To gain a deeper insight, we used a purposive sampling technique, involving in-depth, face-to-face interviews based on a semi-structured questionnaire amongst 185 farmers from the state of the Punjab in India. The combination of open ended and dichotomous questions amenable to the Likert scale, captured responses and the transcribed questionnaires were thematically analysed.

Findings

Using the analysis of the quantitative and qualitative responses, we explain the cause and consequences of the finance gap and the impact of poverty on household income and the debt levels of SMFs. The findings suggest that the expanding pool of SMFs is due to land ownership fragmentation that disenfranchises SMFs from accessing adequate finance thus limiting their ability to adapt to technological innovations, and therefore limiting their productivity and growth. This essentially limits their ability to transform their economic and social wellbeing. The findings from the data analysis suggest a lack of access to finance negatively impacts on SMFs' ability to use innovative practices, technologies and productivity. This adversely affects income level, access to education and social goods to propel them out of poverty. The findings advocate that government policy should focus on land reforms, which provide adequate access to finance to enable the adaption of technology and an access to markets to empower marginal farmers.

Research limitations/implications

Land fragmentation resulting with population growth in emerging economies continuously expands SMFs. To improve efficiency, productivity and entrepreneurial traits amongst SMFs, it is a pre-requisite to have an agile economy. However, in emerging economies such as India, the responses of 185 farmers suggest, a bespoke policy to promote the interest of SMFs through enabling them access to finance, technologies, training and education, continues to prove elusive. This novel empirical research provides evidence that demands that policymakers, commercial institutions and donors need to respond to the needs of SMFs to ensure food security and an optimal utilisation of farmland. The limitation of this research is that the sample is from one country, which limits its generalisation. The findings of this study could be enhanced by conducting comparative studies in other regions or economies.

Originality/value

This empirical study examined the barriers to enterprise for SMFs in the Indian Punjab; it examined the causes and consequences and the implications for food security for India. The findings of this study highlight the importance of developing the entrepreneurial capabilities of SMFs through effective education, training and above all through an adequate access to finance to enable them to adapt their technology. Furthermore, the findings make a case as to why SMFs are an integral part of the food chain and why it is necessary to enhance their efficiency, productivity and their access to finance.

Abstract

Teacher Education has been transforming throughout the world to cater to the emerging needs of quality education. Significant developments have taken place nationally and internationally in political, economic, and cultural fields, influencing education in general and teacher education in particular. The quality of education depends to a great extent on the quality of teachers. And, the quality of teachers depends on the way they are educated and trained. Pakistan has a vast education sector and a huge teaching force but teacher education in the country has not been keeping pace with modernization and development globally. Teacher education curricula, dissemination, evaluation and implementation revolved around traditional models for decades. However, there has been a growing realization to reform the teacher education system lately. The education policy (2009) of Pakistan indicates such realization on the part of the stakeholders. This chapter reports on an important teacher education reform program, which is based on collaboration between the government of Pakistan and the USAID. The Teacher Education Project (TEP), assisted by USAID, is a reform initiative that aimed at restructuring and modernizing teacher education in Pakistan. This chapter aims to provide insights into the objectives, importance and achievements of the project in terms of shaping the future direction of teacher education in Pakistan. It reports on the substantial structural and policy changes that took place in teacher education under the project. This chapter also highlights the possible challenges in the way of useful implementation and sustainability of this and similar education reform initiatives in Pakistan.

Abstract

Purpose

The purpose of this paper is to identify factors affecting sustainable organizational performance, to build a framework for the United Arab Emirates (UAE) public health-care sector to facilitate sustainable organizational performance and to prioritize the factors for sustainable organizational performance.

Design/method/approach

The method used in this research is the quantitative method called the analytical hierarchal process (AHP) to help the decision makers in the public health-care sector to prioritize the factors that are affecting sustainable organizational performance. The method will also help to deal with the complexity of the sustainable organizational performance issue by interviewing nine experts in the field.

Findings

The findings of this research showed 21 sub-factors for sustainable organizational performance in the public health-care sector in UAE. It emphasizes that patient safety and quality of care are the most important factors for sustainable organizational performance.

Research limitations/implications

This study can be repeated by targeting other private hospitals in UAE. The novelty of this research means that it is the first study done in sustainable organizational performance in the health-care sector in UAE.

Practical implications

Health-care management can benefit from this research in many ways: Medical errors have a high impact on the hospital’s reputation and these determine the customer demand. Thus, the hospital’s management should give more attention to minimize the medical errors in order to have a sustainable organizational performance. This can be accomplished through clear protocols and procedures that may affect patients’ lives, the hospital’s reputation and organizational performance. Nevertheless, the policymakers should focus on society engagement; focus on social sustainability should be an integral part of their operational and business strategy. According to Abu Dhabi Health Authority (HAAD), the UAE has a highest rate of chronic diseases, such as diabetes, obesity and cardiovascular disease. Cardiovascular disease itself accounted for 36.7% of all 2013 deaths. The health-care sector should focus more on educating the community by conducting workshops, seminars and awareness campaigns across the UAE. In addition, decision makers in the health-care sector should spend more on continued improvement by focusing on lean activities that focus on waste minimization and linking the service quality to the hospital outcomes and patient satisfaction. The fourth highest overall priority weight for both transformational leadership and for the waiting time sub-criteria should also be considered by top management to focus more on hiring, retaining, and developing their transformational leaders, and to keep an eye on the waiting time and improving customer service. This will result in the sustainable organizational performance. Interestingly, all of the HR processes showed the lowest overall weights at 1%, which is a bit strange. HR should play more of a role in sustainable organizational performance, equal to the other sub-factors.

Originality/value

Originality of this research stems from a reliable and valid framework that can be subsequently used for measuring the organizational performance of health care organizations.

Abstract

The current study aims to use bioecological theory to examine the effects of different contextual factors such as husbands’ desire for children, visit by a family planning worker, media messages, and province level on women’s use of contraception in Pakistan. Two cross-sectional data sets were taken from the Pakistan Demographic and Health Surveys (PDHS), conducted in 2006–07 and 2012–13, which included 3,811 and 4,871 currently married, lower socioeconomic status (SES) women aged 15–49 years, respectively. Using logistic regression, the results showed that women’s perception of a husband’s desire for children and visit by family planning workers were significant predictors of women’s use of contraception in both periods (i.e. PDHS 2006–07 and PDHS, 2012–13). Specifically, those women who had a desire for children similar to their husband were more likely to use contraception than those who either were not sure about their husband’s desire for children or whose desire for children was less or more than their husband. Moreover, those women who had at least one visit from a family planning worker during the 12 months prior to the survey were more likely to use contraception than their counterparts.

Abstract

Purpose

While the sizable body of research focusses on various psychological effects of enterprise social media (ESM), research connecting the link between ESM and cyberslacking is still very sparse. Drawing inspiration from the social bonding theory, the authors have proposed a moderated mediation model to explain how ESM affordances reduce cyberslacking, mediated significantly by workplace social bonding when the perceived co-worker involvement is high.

Design/methodology/approach

Utilising a sample of 384 respondents, the study tested the model fit and hypothesised relationships with AMOS and PROCESS MACRO.

Findings

The findings show that workplace social bonding mediates the relationship between ESM affordances and cyberslacking. The results are also consistent with the moderated mediation model as the mediation is significant when the perceived co-worker involvement is high, and the mediation is insignificant when the moderator is low/moderate.

Research limitations/implications

Considering the potential behavioural dynamics of ESM artefacts, the authors have introduced self-expression (via microblogging), recognition (from paralinguistic digital affordances) and network externality as ESM affordances. Alongside the existing measures to reduce employee deviance, the proposed model with the above-mentioned affordances can be investigated in detail by the future research community.

Practical implications

In light of the findings, the study demonstrates that ESM can be treated as a mechanism to keep cyberslacking at bay. The results offer significant implications for managers, who lookout for innovative and soft strategies to reduce cyberslacking in the workplace.

Originality/value

Instead of implementing strict policies to kerb cyberslacking, this study proposes an alternative and an interesting model by introducing ESM as a strategic tool in reducing cyberslacking. The paper argues that ESM, being a potential tool for employee engagement and bonding, may offset the employees' tendency to involve in cyberslacking.
