The purpose of the present article is to obtain the similarity solution for the shock wave generated by a piston propagating in a self-gravitating nonideal gas under the impact of azimuthal magnetic field for adiabatic and isothermal flows.

The Lie group theoretic method given by Sophus Lie is used to obtain the similarity solution in the present article.

Similarity solution with exponential law shock path is obtained for both ideal and nonideal gas cases. The effects on the flow variables, density ratio at the shock front and shock strength by the variation of the shock Cowling number, adiabatic index of the gas, gravitational parameter and nonidealness parameter are investigated. The shock strength decreases with an increase in the shock Cowling number, nonidealness parameter and adiabatic index, whereas the strength of the shock wave increases with an increase in gravitational parameter.

Propagation of shock wave with spherical geometry in a self-gravitating nonideal gas under the impact of azimuthal magnetic field for adiabatic and isothermal flows has not been studied by any author using the Lie group theoretic method.

This paper aims to identify and study the effect of identified eight barriers to sustainable consumption on consumers’ intention to purchase sustainable products.

Data were collected from a self-administered field survey in India, and 315 valid responses were obtained from the survey process. Partial least square structural equation modeling analysis was carried out to establish the validity of the measures used and to examine the impact of the identified barriers on sustainable purchase intentions.

The results of this study indicate that barriers such as low willingness to pay, low functional performance, low availability of sustainable products and difficulty of integration in the normal route have a statistically significant negative impact on consumers’ sustainable purchase intentions.

The findings of this study are useful for marketers and policymakers who want to increase the consumer adoption of sustainable products in emerging markets.

This study develops measures to capture the consumers’ perception of barriers to the adoption of sustainable products.

This study aims to provide the best estimate of a stock's next day's closing price for a given day with the help of the hidden Markov model–Gaussian mixture model (HMM-GMM). The results were compared with Hassan and Nath’s (2005) study using HMM and artificial neural network (ANN).

The study adopted an initialization approach wherein the hidden states of the HMM are modelled as GMM using two different approaches. Training of the HMM-GMM model is carried out using two methods. The prediction was performed by taking the closest closing price (having a log-likelihood within the tolerance range) to that of the present one as the closing price for the next day. Mean absolute percentage error (MAPE) has been used to compare the proposed GMM-HMM model against the models of the research study (Hassan and Nath, 2005).

Comparing this study with Hassan and Nath (2005) reveals that the proposed model outperformed in 66 out of the 72 different test cases. The results affirm that the model can be used for more accurate time series prediction. Further, compared with the results of the ANN model from Hassan's study, the proposed HMM model outperformed 24 of the 36 test cases.

The study introduced a novel initialization and two training/prediction approaches for the HMM-GMM model. It is to be noted that the study has introduced a GMM-HMM-based closing price estimator for stock price prediction. The proposed method of forecasting the stock prices using GMM-HMM is explainable and has a solid statistical foundation.

The purpose of this paper is to provide an initial analysis of the roles of functional capabilities in adopting environmental management practices (EMP) and improving environmental performance from an organizational capability perspective.

By combing survey data and archival data from 121 UK-based manufacturing firms, this study explores the relationships among functional capabilities (marketing and operations), EMP and environmental performance.

The results show that marketing and operations capabilities significantly affect EMP, which in turn leads to improved environmental performance. More specifically, this study finds that EMP fully mediates the relationship between marketing capability and environmental performance.

The results of this study provide guidance for managers considering how to develop environmental capability in order to improve environmental performance.

This study addresses a demonstrable gap in the existing literature that few empirical studies have explored the potential effects of functional capabilities on implementing EMP.

Purpose – This research in this paper aims to investigate and extend the trust‐relationship commitment model to an internet banking setting by adding attraction as a new factor. Design/methodology/approach – The paper shows that in testing whether attraction might be related to belief in and use of the internet banking, this research sampled 276 bank customers' responses via a cross‐sectional survey in Doha, Qatar. Findings – The findings in the paper indicate that both trust and attraction have significant positive impact on relationship commitment with attraction having a strong positive effect, with communication representing the most important determinant of attraction and having a significant positive relationship with both trust and attraction. Practical implications – The paper shows that, from the managerial perspective, it is necessary for bankers and policy makers to know the relationship between trust and attraction because their influence on the actual commitment is different The findings of this study suggest that, in order to develop trust and to attract more users to internet banking, it is not going to be enough to make the system easy to interact with. It is of paramount importance for banks to develop secured and private internet banking systems that are trustworthy, for their users. Thus, management attention might be fruitfully focused on the development of such beliefs on the part of the users. Thus, the internet banking authorities should employ training and promotion approaches to develop customers' beliefs of shared value, communication, and opportunistic behavior, which in turn will influence or attract the customers' behavioural intention to utilize internet banking services. Similarly, banks may consider offering a low‐cost service by passing on some of their gains from reduced operating cost to customers. This may lead to better customer loyalty towards the service. Originality/value – The paper finds that attraction as an additional factor in a trust‐relationship commitment model has not been examined before. Thus, researchers should include attraction in online relationship banking models along with other relationship effects. Also, bankers and policy makers need to develop trust among the customers and to realize that more favorable communication environments must be created to attract customers and to make them more committed to using online banking transactions over the internet.

The purpose of this paper it to examine Electronic commerce (e-commerce) practices of Iranian business organizations, as a “traditional” business culture, as it compares to a “developed” business culture such as the one existing in business organizations in the USA.

Executives from a sample of 50 business organizations in Iran were interviewed and asked to complete the research questions pertaining to e-commerce practices in their organizations. A factor analysis procedures with varimax rotations is used to analyze the data collected from these organizations.

Comparing the result of this study with an earlier study on a sample of business organization in the USA shows more similarities than differences. Based on the results of the study, it appears that e-commerce practices and related technology present similar opportunities and challenges to organizations regardless of their business culture. Lack of appropriate technological hardware and software, however, is identified as a hindering factor preventing Iranian business organizations from reaching their e-commerce potentials.

This research provides a rare insight into the Iranian business culture. The collection of data through personal interviews and the empirical nature of the study represent a unique opportunity to validate findings from other business cultures. This allows for a better practical understanding of the opportunities and constraints associated with e-commerce adoption.

The Supreme Court judgement, Kailash Nath Associates v. Delhi Development Authority consolidates the law on award of liquidated damages and stipulations on penalties. Contractual damages are to cover losses and not to profit from or penalise the party in breach. Stipulated amounts in damages or penalties are appraised by the courts and only a reasonable compensation is given. Earnest money, and its forfeiture, stood distinct. It could be forfeited without appraisal. The case integrates the different categories and re-states the principles for award of damages.

The purpose of this study is to investigate the factors affecting the intention to adopt blockchain technology (BT) in operations and supply chain and to explore the moderating role of sustainability-oriented supplier development on the effects studied.

The authors developed a conceptual framework based on the integration of technology-organization-environment (TOE) framework and diffusion of innovation (DOI) theory along with several strands of the literature in supply chain management and information systems. Drawing on survey data from 412 supply firms, a novel model using partial least squares structural equation modeling (PLS-SEM) was empirically tested in the context of the apparel industry of Bangladesh – the world's second-largest apparel supplier nation.

The findings supported the theoretical framework developed. In particular, the findings suggested that supplier firms' intention to adopt blockchain in supply chains is influenced by relative advantage, compatibility, perceived trust, top management considerations, absorptive capacity, information sharing and collaborative culture, and trading partners' influence. However, regulatory support is yet to play a significant role in blockchain adoption behaviour. The findings also suggest that supplier development for sustainability significantly moderates the relationship between the several drivers' (e.g. relative advantage, compatibility, top management considerations and trading partners' influence) effects on blockchain adoption.

The findings could help in developing an enabling environment for introducing blockchain-based apparel operations and supply chains.

The study contributes to and expands the embryonic research stream of sustainable supply chain management and BT. In particular, the paper provides neoteric evidence on how supplier development towards achieving sustainability moderates the effects of organizational, technological, and environmental drivers on the intention to adopt BT.

The purpose of this paper is to investigate effects of layer thickness on densification, surface morphology, microstructure and mechanical and corrosion properties of 420 stainless steel fabricated by laser-powder bed fusion (L-PBF).

Standard specimens were printed at layer thickness of 10, 20 and 30 µm to characterize Archimedes density, surface roughness, tensile strength, elongation, hardness, microstructural phases and corrosion performance in the as-printed and heat-treated condition.

Archimedes density slightly increased from 7.67 ± 0.02 to 7.70 ± 0.02g/cm³ and notably decreased to 7.35 ± 0.05 g/cm³ as the layer thickness was changed from 20 µm to 10 and 30 µm, respectively. The sensitivity to layer thickness variation was also evident in properties, the ultimate tensile strength of as-printed parts increased from 1050 ± 25 MPa to 1130 ± 35 MPa and decreased to 760 ± 35 MPa, elongation increased from 2.5 ± 0.2% to 2.8 ± 0.3% and decreased to 1.5 ± 0.2, and hardness increased from 55 ± 1 HRC to 57 ± 1 HRC and decreased to 51 ± 1 HRC, respectively. Following heat treatment, the ultimate tensile strength and elongation improved but the general trends of effects of layer thickness remained the same.

Properties obtained by L-PBF are superior to reported properties of 420 stainless steel fabricated by metal injection molding and comparable to wrought properties.

This study successfully the sensitivity of mechanical and corrosion properties of the as-printed and heat-treated parts to not only physical density but also microstructure (martensite content and tempering), as a result of changing the layer thickness. This manuscript also demonstrates porosity evolution as a combination of reduced energy flux and lower packing density for parts processed at an increasing layer thickness.

This paper aimed to explore the presence of altmetric data across the sub-categories of the medical science discipline and also explore whether the openness of articles results in (dis)advantage for altmetrics mentions.

The research implies data carpentry methods for gathering bibliographic data related to narrow fields of medical science discipline from the Scopus database with at least one Indian author affiliation during 2012–2021. The corresponding data were also collected from three different sources: Altmetric.com, Mendeley.com and Unpaywall.org, using OpenRefine and REST/API calls. Further, the authors observed open access altmetric advantages (OAAA) and categorical OAAA (COAAA) across seven altmetric platforms for all articles as well as discipline-wise.

The result shows that the overall coverage of altmetric events is still low, but it shows an increasing trend from the past. Mendeley has the largest coverage; almost 97.12% of publications are covered. The health policy discipline has extensive coverage across altmetric platforms (nearly 57.40% of publications in altmetrics and 99.23% in Mendeley), whereas the drug guides has the lowest (almost 0.92% in Altmetrics and 77.05% in Mendeley). Moreover, the OA articles have been highly covered in altmetrics than those of non-OA articles, and bronze OA articles covered mostly compared to others. News registered with the significant OA altmetric advantages across disciplines. Categorically, bronze and hybrid OA have the largest altmetric advantages.

This research is a unique attempt to apply OAAA and COAAA to explore OA altmetric advantages of narrow subject categories of medical science disciplines.
