The purpose of this paper is to identify the barriers halting the usage of sustainable modes of transportation in a university campus.

Two large-scale universities, namely, Quaid-i-Azam University and the National University of Sciences and Technology, in Islamabad have been taken as case studies with a sample population of 421. The questionnaire data, comprising 30 different barriers, were analysed by principal component analysis and mean value method.

The findings indicate that safety and infrastructural factors are the most influential ones affecting sustainable mobility within the campus. The provision of user-friendly and safe infrastructure and more frequent shuttle buses are recommended to promote the culture of sustainable transportation.

Inclusion of other large-scale universities of the country might give more generalized results. The sustainability of other areas associating with transportation can also be evaluated to explore other unfamiliar dimensions.

The outcome of this research expects to highlight important policy recommendations for the promotion of sustainable mobility inside the campus and also serves as a guiding principle for campus developers and policymakers for planning new campuses in other parts of the country.

This research can be considered as a starting point for achieving sustainability in the universities of Pakistan. The same research methodology can be opted in other campuses with the possibility of the addition of other related factors with different statistical analysis techniques as well.

The purpose of the paper is to study natural convection within porous square and triangular geometries (design 1: regular isosceles triangle, design 2: inverted isosceles triangle) subjected to discrete heating with various locations of double heaters along the vertical (square) or inclined (triangular) arms.

Galerkin finite element method is used to solve the governing equations for a wide range of modified Darcy number, Da_m = 10⁻⁵–10⁻² with various fluid saturated porous media, Pr_m = 0.015 and 7.2 at a modified Rayleigh number, Ra_m = 10⁶ involving the strategic placement of double heaters along the vertical or inclined arms (types 1-3). Adaptive mesh refinement is implemented based on the lengths of discrete heaters. Finite element based heat flow visualization via heatlines has been adopted to study heat distribution at various portions.

The strategic positioning of the double heaters (types 1-3) and the convective heatline vortices depict significant overall temperature elevation at both Da_m = 10⁻⁴ and 10⁻² compared to type 0 (single heater at each vertical or inclined arm). Types 2 and 3 are found to promote higher temperature uniformity and greater overall temperature elevation at Da_m = 10⁻². Overall, the triangular design 2 geometry is also found to be optimal in achieving greater temperature elevation for the porous media saturated with various fluids (Pr_m).

Multiple heaters (at each side [left or right] wall) result in enhanced temperature elevation compared to the single heater (at each side [left or right] wall). The results of the current work may be useful for the material processing, thermal storage and solar heating applications.

The heatline approach is used to visualize the heat flow involving double heaters along the side (left or right) arms (square and triangular geometries) during natural convection involving porous media. The heatlines depict the trajectories of heat flow that are essential for thermal management involving larger thermal elevation. The mixing cup or bulk average temperature values are obtained for all types of heating (types 0-3) involving all geometries, and overall temperature elevation is examined based on higher mixing cup temperature values.

The interaction of consumers and technology has become a challenge for companies and marketing professionals. Technological acceleration has transformed how business is conducted and the consumer-company relationship. The need to establish communication with (potential) consumers to promote engagement with the brand highlights the importance of using mobile instant messaging (MIM). In this context, this paper aims to investigate the use of MIM as a tool for interaction between companies and consumers.

This article investigates, through a systematic literature review (SLR), the state of the art of scientific research regarding the use of MIM as a tool for interaction between companies and consumers. To analyze the selected articles, the authors used a research protocol composed of three stages: (1) planning, (2) conducting and (3) disseminating knowledge.

This study made four main contributions to the MIM field: (1) extends the literature on MIM, focusing on the perspective of companies and consumers; (2) expands the ongoing discussions, suggesting the limited availability of research on MIM as a tool for interaction between companies and consumers; (3) development of a typology composed of three classes, namely “Consumer relationship,” “Social interaction and technology, and “Social media as channels strategy”; (4) the fourth contribution concerns identifying future research areas and answering questions.

This article is the first to investigate, through a SLR, the state of the art of scientific research regarding the use of MIM as a tool for interaction between companies and consumers.

Managing a safety programme and ensuring that change is in accordance with suitable performance measures requires continuing improvement in the support of analytical power and empirical information. This paper aims to consider different approaches and modeling efforts on safety performance evaluation.

Review and synthesis of literature.

Ten major safety performance evaluation approaches are identified including expectation function, risk assessment, statistical quality control, price deflation, engineering economic factor, system analysis, artificial intelligence, and systems theory. Based on the approaches, quantitative and qualitative models have been proposed. The quantitative models use measuring indicators such as frequency, severity, percentages, relative weight and economic gains/loss of safety programme. However, qualitative models employ hazard analysis and hazard operability.

Several research questions remain to be answered in order to completely improve and optimize the impact of these provisional safety performance measures.

This study offers a set of interesting lessons for academics, industry and safety practitioners by providing guidelines that will assist in ensuring a correct focus to select an appropriate safety performance evaluation model.

The cheapest and most rapidly available metal for agro‐processing equipment fabrication in Nigeria is plain carbon steel. However, there are some aggressive ions present in raw agricultural and food products, which may attack the steel components of these processing machinery, resulting in their untimely failure in service. The present study investigates the effect of fluid squeezed from cassava tuber on the corrosion behaviour of mild steel.

The investigation involved periodic weight loss measurements of 0.8 per cent carbon and 0.36 per cent carbon steel rods as they were exposed to cassava fluid. The relationships between loss in weight of the exposed samples and exposure period were determined. Models were developed to relate corrosion rate in each environment with total surface area and exposure period.

The results show that 0.36 per cent carbon steel was less affected by corrosion than 0.18 per cent carbon steel, with corrosion intensity in both cases, increasing with duration of immersion. Generally, there was low level of corrosion resistance (high corrosion rate) by the two steel materials. The correlation coefficient between the experimental values of corrosion rates and predicted values (using the developed models) was high.

In food and agricultural industries, product quality, health and sanitation issues are the major concerns. The industries cannot tolerate corrosion deposits in the manufactured products. Hence, material selection for machinery fabrication is essential. In line with this, the results of this study indicate that mild steel materials are unsuitable for use in cassava processing without some forms of surface treatment.

The disruptive human resource management (HRM) technologies are now considered a significant facilitator to change and benefit the entire HRM landscape. This view needs to be further verified by reviewing the knowledge on the subject in the empirical research landscape. Thus, the study's objectives were to find (1) the current knowledge and (2) the areas where empirical research is lacking in disruptive HRM technologies.

The article is a literature review that was followed by the systematic literature review and the preferred reporting items for systematic reviews and meta-analyses (PRISMA). The review considered 45 articles published during the 2008–2021 period extracted from the Scopus database, and bibliometric analysis was performed to achieve the research objectives.

The results found that scholarly attention has been given to electronic HRM (E-HRM) rather than the disruptive HRM technologies. The areas investigated include the determinants of intention, adoptions and use of E-HRM and the outcomes of E-HRM adoptions and use. These outcomes can be further divided into general outcomes and HRM outcomes.

The findings reveal gaps in E-HRM research and disruptive HRM technologies remain untapped in the empirical research landscape. Hence, the study findings provide some implications for future research and applications.

The study found empirically proven determinants of E-HRM intention, adoptions and use and E-HRM adoptions and use outcomes. These were found in the studies conducted during the 2008–2021 period.

The purpose of this paper is to investigate tractor maintenance practices and costs in Nigeria with a view to making replacement decisions and for overall farm budgeting.

The information was obtained via a structured questionnaire. Tractor owners were grouped into three categories: government agricultural settlements, established farms, and individual farms. Data used for analysis were collected from 60 farms located in major farming centers of the southwestern part of Nigeria. The report includes the formulation of repair equations, which relate tractor repair cost as a percentage of initial purchase prices to cumulative hours of use. Life cycle costs of three commonly‐used tractors were also estimated. The derived equations, which showed that the repair costs per hour increased with hours of use, were used to obtain the life cycle cost of each tractor model in different tractor owners' farms.

The proposed equation was found to be the best fit with coefficient of determination (R²) ranging from 0.992 to 0.996 for tractors in the three user categories. The trend observed in the life cycle costing of the three common tractors gave the general picture of when to replace each of the tractors based on the strategies being adopted by the tractor owners.

The results of this study would serve as baseline information to tractor owners regarding optimum use of tractors for minimizing repair and maintenance cost per hour and for making replacement policy. It would also be helpful to government and other agencies for future planning in the provision of tractor services to the farmers at relatively lower repair and maintenance cost.

Proves that a reduction in repair costs by careful operation and adequate maintenance could result in a significant reduction in tractor ownership costs.

In the competitive business world, companies strive to be innovative, and to do so, they try to implement innovative human resource practices. Therefore, the authors propose an association between innovative human resource practice, organizational commitment, innovation performance and transformational leadership.

This study gathered data from 1,037 small- and medium-sized enterprises and implied partial least square structural equation modeling PLS-SEM using Smart PLS was adopted to test the hypotheses.

The findings reveal positive direct relationships between innovative human resource practices, organizational commitment and innovation performance. Moreover, organizational commitment positively mediates and transformational leadership significantly and positively moderates the relationship. Companies should use innovative recruitment and selection, performance management, and innovative compensation to enhance organizational commitment and innovation performance. In addition, the optimized organizational commitment aids in strengthening the connection between innovative human resource practices and firms' innovation performance.

Managers should also develop a sense of affiliation and attachment to increase innovation performance. The study contributes empirically to the literature on innovative human resource practices and their effect on organizational commitment and innovation performance.

Housing prices have been increasing tremendously in Pakistan, there should be many reasons but the haphazard urbanization and rapidly growing population. To find out the causes of this price rise, this study aims to assess the impact of the foreign capital inflow and some domestic factors on housing prices.

To get the benefits of high-frequency data, it has been converted into a monthly, quarterly and yearly basis. The unit root is performed to see the stationarity, Johansen test is used for cointegration and coefficients are obtained through the ordinary least squares technique. The robustness of the results is checked with dynamic ordinary least squares and the Chow breakpoint test is used to detect structural breaks.

The housing prices have increased over time; this has been reflected in all the data sets under observation. The country has observed a rapid growth in population and urbanization that has badly affected almost every activity of city life. The impact of foreign capital inflow is positive on the house price appreciation. There is a dire need to divert such foreign funds in the housing sector so that it cannot create an artificial price hike. The government should regularly publish a housing policy for the guidance of investors and the public at large. Also, public authorities should provide housing finance facility.

This is a novel work to the best of the authors’ knowledge because no one has studied the impact of foreign capital inflow on the housing market for the economy of Pakistan. Furthermore, this study is different in the sense that it has disaggregated annual data into a monthly and quarterly basis to get the benefits of high-frequency data.
