The purpose of this paper is to contribute to the human resources (HR) literature by using exploratory network analysis (ENA), a data-driven technique. This technique was employed to discover how the perceived effectiveness of HR practices interrelate with employee perceptions on organizational cultural factors to enhance organizational commitment.

The authors used data from 1,459 employees of a large South Korean conglomerate and studied how individual HR practices could be enhanced by specific organizational cultural factors. The data were analyzed using ENA, which is an inductive approach.

The authors found that organizational commitment is associated with the positive perceptions of employees on the effectiveness of HR practices, such as performance appraisal, training and development, and compensation. Results show that when both HR practices and organizational cultural factors are considered, they appear to influence organizational commitment independently.

Data were collected from a large conglomerate. The authors were limited by the use of the scales developed by a consulting firm. Therefore, readers should be cautious about the generalizability of the findings.

The application of a data-driven technique (ENA) highlights the potentially fertile methodological grounds for HR research. Literature on strategic HR management may benefit from inductive approaches, wherein data serve as primary foundation for the design and development of new theories.

Since the inception of aerospace engineering, reducing drag is of eternal importance. Over the years, researchers have been trying to improve the aerodynamics of National Advisory Committee for Aeronautics (NACA) aerofoils in many ways. It is proved that smooth-surfaced NACA 0012 aerofoil produces more drag in compressible flow. Recent research on shark-skin pattern warrants a feasible solution to many fluid-engineering problems. Several attempts were made by many researchers to implement the idea of shark skin in the form of coatings, texture and more. However, those ideas are at greater risk when it comes to wing maintenance. The purpose of this paper is to implement a relatively larger biomimetic pattern which would make way for easy maintenance of patterned wings with improved performance.

In this paper, two biomimetic aerofoils are designed by optimizing the surface pattern of shark skin and are tested at different angles of attack in the computational flow domain.

The results of the biomimetic aerofoils prove that viscous and total drag can be reduced up to 33.08% and 3.68%, respectively, at high subsonic speed when validated against a NACA 0012 aerofoil. With the ample effectiveness of patched shark-skin pattern, biomimetic aerofoil generates as high as 10.42% lift than NACA 0012.

In this study, a feasible shark-skin pattern is constructed for NACA 0012 in a transonic flow regime. Computational results achieved using the theoretical model agree with experimental data.

As the complexity and uncertainty of infrastructural megaprojects challenge traditional management models, there is an increasing focus on value co-creation as an organizational strategy to streamline management. However, the role of value co-creation behavior in facilitating the value realization process remains underexplored. This study examines how justice perception (distributive, procedural and interactional justice) improves contractor value co-creation behavior, focusing on the mediating role of psychological ownership.

Ten hypotheses in the proposed research model were tested through partial least squares structural equation modeling using 199 valid questionnaires from China.

The results show that contractor value co-creation behavior is directly and positively influenced by procedural, distributive and interactional justice and indirectly influenced by them through the underlying psychological mechanism of psychological ownership.

The findings fill a knowledge gap by examining the effect of justice perception on contractor value co-creation behavior based on social exchange theory. Discovering justice perception will contribute to contractor value co-creation behavior, and psychological ownership mediates this relationship.

The purpose of this paper is to examine the relationship between accounting conservatism and pledging of shares by controlling shareholders of a firm to obtain a loan. The pledging of shares by the controlling shareholders of a firm results in alterations to the payoff and risk structure for these shareholders. Since accounting numbers have valuation implications, pledging of shares by a controlling shareholder has an impact on accounting policy choices made by the firm. The purpose of this paper is to examine the impact of controlling shareholder share pledging to obtain a loan on a specific accounting policy choice, namely, conservatism.

The paper uses a large data set from India comprising 14,786 firm years consisting of 1,570 firms belonging to 58 industries for a period of 11 years (2009–2019). The authors use ordinary least square regression with robust standard errors. The authors conduct robustness checks and the results are consistent across alternative statistical methodologies and alternative measures of the primary dependent and independent variables.

The primary results show that pledging of shares by the controlling shareholders results in higher conditional conservatism and lower unconditional conservatism. Further analysis reveals that the relationship is stronger when the controlling shareholder holds a majority ownership in the firm. Additionally, the results show that for business group affiliated firms, which are unique to developing countries, both the conditional and the unconditional conservatism are incrementally lower when the controlling shareholder pledges the shares. For family firms with a family member as CEO, the conditional conservatism is incrementally higher and the unconditional conservatism is incrementally lower. Finally, the authors show that the results hold when the pledge intensity variable is measured with a one-year lag and finally, the authors show that conditional conservatism is incrementally higher in the year of the increase in the pledge and the year after, but there is no such incremental impact on unconditional conservatism.

The research is limited to the listed firms in India. Since majority of the listed firms are controlled by families and the family firms around the world are heterogeneous the findings of the research may not be applicable to other countries.

The study has implications for policy-making and monitoring of the pledging by the controlling shareholders. It also helps the investors in making investment decisions with respect to family firms in India.

The study is unique as it focuses on the relationship between pledging of shares by the controlling shareholders and its impact on accounting conservatism. To the best of the authors’ knowledge, this is the first research integrating these two aspects.

Much research has explored high levels of son preference in India, finding that parents often report a desire for more sons than daughters. While scholars have noted that a nontrivial portion of respondents claim to have no sex preference, little is known about (1) the characteristics of this group and (2) how such parental preferences relate to child outcomes. We use data from a representative study of rural South Indian households (n = 7,891 adults) to address these gaps. Descriptive results show that a sizable portion of respondents – one in four – indicated that, at the start of their marriage, they had no preference for the number of daughters or sons they wanted. Further, multinomial regression results show that those who reported no sex preference at the time of marriage were more likely to be female, older, and less likely to be sterilized than those who reported equal or son preference, with additional distinctions across educational attainment and religion. Turning to child-level outcomes, we examined whether parents’ sex preferences related to adolescent mental health through ordinary least squares (OLS) regression models (n = 1,245 adolescents). Adolescents whose mothers stated no sex preference reported significantly fewer anxiety and depressive symptoms than their peers. Fathers’ sex preferences were not significantly related to adolescent mental health. These findings suggest that a lack of sex preference may hold meaningful and positive implications for adolescent mental health. Further, although son preference is a widespread phenomenon, singular attention on those with son preference may mask important nuances among Indian families.

The purpose of this paper is to numerically investigate steady, laminar natural and mixed convection heat transfer in a two-dimensional cavity by using a finite volume method with a fourth-order approximation of convective terms, with and without the presence of nanoparticles. Highly accurate benchmark results are also provided.

A finite volume method on a non-uniform staggered grid is used for the solution of two-dimensional momentum and energy conservation equations. Diffusion terms, in the momentum and energy equations, are approximated using second-order central differences, whereas a non-uniform four-point fourth-order interpolation (FPFOI) scheme is developed for the convective terms. Coupled mass and momentum conservation equations are solved iteratively using a semi-implicit method for pressure-linked equation method.

For the case of natural convection problem at high-Rayleigh numbers, grid density must be sufficiently high in order to obtain grid-independent results and capture reality of the physics. Heat transfer enhancement for natural convection is observed up to a certain value of the nanoparticle volume fraction. After that value, heat transfer deterioration is found with increasing nanoparticle volume fraction.

Developed a non-uniform FPFOI scheme. Highly accurate benchmark results for the heat transfer of Al₂O₃-water nanofluid in a cavity are provided.

The purpose of this paper is to investigate the effect of current carbon tax (CT) policy on organizations involved in a sharing network relation.

For finding the CT and economic value of the industries connected in a sharing network model a multi-objective multi-integer linear model has been formulated. The data set of the case organization is used for computation. The formulated mathematical model is computed with the aid of GAMS optimization program.

This research paper demonstrates the effectiveness of the sharing network strategy in increasing the economic value and decreasing the CT for industries involved in sharing network. The CT value INR 3,012.694 for the industries in Scenario II which incorporates the sharing network is less than the CT INR 3,580.167 for industries in Scenario I without sharing network.

The data used for the computation is based on a particular sharing network under investigation. The formulated mathematical model can be checked with similar sharing networks by varying the parameters.

This work can aid in gaining complete knowledge on the sharing network strategy which can uplift the resources and the monetary value of the non-efficient industries moving them towards sustainable and greener supply chain practices.

The presented work can impact various industries in developing countries providing them with a strategy to enhance their resources and economic value by maintaining an amicable relation.

This work uniquely was able to validate economic feasibility and CT in accordance with the carbon footprint involved in sharing network. This sharing network also incorporates the concepts of circular economy and reverse logistics for showcasing a better strategy.

Inconel 718 is difficult to machine due to its high toughness and study hardenability. Though the use of cutting fluids alleviates the problem, it is not sustainable. So, supply of a small quantity of specialized coolant to the machining zone or use of a solid lubricant is a possible solution. The purpose of the present work is to improve machinability of Inconel718 using graphene nanoplatelets.

In the present study, graphene is used in the machining of Inconel 718 alloy. Graphene is applied in the following two forms: as a solid lubricant and as an inclusion in cutting fluid. Graphene-based self-lubricating tool and graphene added nanofluids are prepared and applied to turning of Inconel 718 at varying cutting velocities. Performances are compared by measuring cutting forces, cutting temperature, tool wear and surface roughness.

Graphene, in both forms, showed superior performance compared to dry machining. In total, 0.3 Wt.% graphene added nanofluids showed the lowest cutting tool temperature and flank wear with 44.95% and 83.37% decrease, respectively, compared to dry machining and lowest surface roughness, 0.424 times compared to dry machining at 87 m/min.

Graphene could improve the machinability of Inconel 718 when used in tools as a solid lubricant and also when used as a dispersant in cutting fluid. Graphene used as a dispersant in cutting fluid is found to be more effective.
