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.

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).

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.

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

The non-circular journal bearings may be used over circular journal bearings because of their superior thermal stability. The paper aims at experimental study of thermal performance of two different true elliptical and orthogonally displaced non-circular journal bearing profiles.

The experiments have been conducted on a specially designed test rig which simultaneously evaluates oil film pressure and temperature along the circumference of non-circular journal bearing. The tests are conducted for the designed true elliptical and orthogonally displaced journal bearing at three different rotational speeds of 2,000, 3,000 and 4,000 rpm under the influence of steadily applied load varied from 0.5 to 2.0 kN. The data collected during experimentation have been used to evaluate thermal performance parameters such as maximum pressure, flow rate and effective temperature of the bearings under study.

It has been observed experimentally that two lobes of pressure and temperature have been obtained for both the elliptical and orthogonally displaced journal bearing. The negative pressure zone (cavitation area) has been observed to be reduced along the circumference for both the journal bearings which results in less thermal degradation of an oil as compared to circular journal bearing. The oil film pressure and temperature increases with the increase in radial load of both the bearings. The maximum temperature rise of oil film is more in case of elliptical bearing as compared to the orthogonally displaced bearing.

The experimental data presented in this paper will help the designers to select such kind of non-circular journal bearing for various applications. The designed bearings have resulted in reduced cavitation zone and two positive pressure lobes have been observed which may result in application of such bearings as an alternate for circular journal bearing.

Samar Singla, the Chief Executive Officer of Jugnoo, had sensed a business opportunity in auto rickshaw aggregation. He was convinced that being among the initial players in the market of auto rickshaw aggregation, there would be very little competition. He only had to play his cards right, to become the top auto aggregator. As Singla started the business, there were challenges like inducting the auto rickshaw drivers as partners, training them, hiring the right team, putting the right strategies in place and to expand the business. Singla launched and achieved robust growth in the new business, in a short period of time. Soon, however, Jugnoo felt competition breathing down their neck – form cab aggregators who were already dominant players in the cabs aggregation segment, in the large cities. To hedge their risks, Singla added other services such as “Meal” (meal delivery) and “Fatafat” (goods delivery) – as B2C and B2B services. These services, however, had to be closed soon after because of stiff competition from the local players. Singla also adopted the inorganic growth path by acquiring “Sabkuch,” a grocery delivery logistics firm; “Yelo,” a platform that provided online access to businesses and “BookMyCab,” a taxi aggregation company. Faced with tapering growth after an initial steep rise, Singla had to confront a dilemma about the right method of ensuring growth in the face of competition.

Augmented Reality (AR) and Virtual Reality (VR) technologies possess the potential to transform the scenario of making real estate investment decisions through the immersive experience they offer. From the literature it was observed that the research in this domain is still emergent and there is a need to identify the latent variables that influence real estate investment decisions. Therefore, by examining the effects of these technologies on investment decision-making, the purpose of the study is to provide valuable insights into how AR and VR could be applied to enhance customers' property buying experiences and assist in their decision-making process.

From an extensive review of the literature four latent variables and their measure were identified, and based on these a survey instrument was developed. The survey was distributed online and received 300 responses from the respondents including home buyers, developers, AEC professionals and real estate agents. To validate the latent variables exploratory factor analysis was used whereas to establish their criticality second-order confirmatory factor analysis was used.

From the results, the four latent constructs were identified based on standard factor loadings (SFL) that is Confident Value Perception (CVP, SFL = 0.70), Innovative Investment Appeal (IIA, SFL = 0.60), Trusted Property Transactions (TPT, SFL = 0.58) and Effortless Property Engagement (EPE, SFL = 0.54), that significantly influence investor decision-making and property purchase experience.

This study contributes to the literature on real estate investment decisions by providing empirical evidence on the role of AR and VR technologies. The identified key variables provided practical guidelines for developers, investors and policymakers in understanding and leveraging the potential of AR and VR technologies in the real estate industry.

Work-from-home (WFH) has gained popularity over the past years. This study aims to conduct a bibliometric analysis to systematically review and synthesize scholarly literature on the complex interplay between WFH, employee well-being and performance.

The study incorporates analysis of the bibliometric including performance analysis, content analysis and scientific mapping that is applied to 497 Scopus papers. VOSviewer software was used to evaluate the data.

This study posits an imbalance between the count of documents and the citations earned by each author. International Journal of Environmental Research and Public Health was regarded as a leading journal with maximum citations and publications. The highest count of publications came from most Asian countries such as India, China, Indonesia and Japan. The investigation indicated that the writers with the maximum citations were predominantly the authors of the majorly cited papers. Further, the text mining through co-occurrence of keyword analysis generated five clusters and cocited references revealed three themes.

The current research might benefit both research groups as well as human resource professionals since it also reveals the research necessity and gaps in the WFH domain.

This research delves into unexplored facets of WFH beyond traditional studies over the past decade by examining remote work arrangements in today’s economy, revealing previously unnoticed dynamics affecting employee well-being and performance. This innovative viewpoint enhances the literature and provides an empirical foundation for strategic organizational decision-making and future study.

The purpose of this paper is to find the effect of the hedonism value on the investment preference in India.

Based on the literature review, a measurement model is developed to measure hedonism. Further, the effect of hedonism on investment choices of an individual and the impact of age, gender and income level on investment choices and on hedonism are also measured through a structural equation model (SEM).

The study finds that the measurement model is reliable, and all five items, that is an exciting life, happiness, pleasure, social recognition and a comfortable life, are an appropriate measure of hedonism. The study finds that hedonists prefer to invest in stock market-related instruments and real estate. The study also ascertains that age and income affect the hedonism value negatively. The findings also indicate that women prefer to invest in fixed income instruments and men prefer to invest in stock market-related instruments. As people grow in age, they prefer to invest in fixed-income instruments and gold as a hedge, thus avoiding risky investments.

The study does not include education and financial literacy of individuals in the model, rather controls these factors by selecting a sample where the minimum educational qualification of the respondent is graduation.

It is assumed that the values that drive an individual have the potential to influence his/her investment choices. Therefore, the study advises the firms offering investment services to their clients to ensure that apart from studying the demographic and risk profile of individuals, they also assess their value system. This can help them target their customers more precisely and serve them better.

The study is perhaps the first attempt to find the effect of personal values (specifically hedonism) on investment choices made by individuals, through the development of an SEM.

The study aims to find if family-owned construction and real estate firms in India are more profitable compared to non-family-owned construction and real estate firms. The study also examines if family ownership and institutional ownership are drivers of the firm profitability.

The study uses data of 199 construction and real estate firms listed on the National Stock Exchange (NSE), India. The data pertains to a period of 13 years (2006-2018). The family firm is defined on the basis on ownership criteria, and the sample is divided into two groups, namely, family firms and non-family firms. The data is analyzed using a two-sample t-test assuming unequal variance and Prais–Winsten panel regression using correlated panels with corrected standard errors (PCSEs) procedure.

The findings suggest that family-owned construction and real estate firms are slightly more profitable compared to non-family-owned construction and real estate firms; however, family firms command lesser valuation in the market. The reason for this lower valuation is the mismatch between family holding and institutional holding. A family firm’s profitability is primarily driven by institutional holding that acts as mitigation against the agency conflict.

The paper is the first attempt to analyze the profitability of construction and real estate family firms, and compare it with non-family-owned construction and real estate firms.

The study examines organization citizenship behavior (OCB) as a mediating variable between instrumental work values (IWVs) and organizational performance; and group differences between family manager and nonfamily manager for integrated models in family hotels. Data were collected from 189 hotels (n = 921) ranging from budget to three-star family hotels in Ghana using questionnaire administered conveniently. Data were analyzed using structural equation modeling. Work value positively influences OCB and organizational performance of family hotels. OCB mediates the relationship between work values and organizational performance. The study also found significant support for group differences between family and nonfamily firms for IWVs and mediating effect of OCB on the relationship between IWVs and performance.
