Abstract

Purpose

The numerical solution of third-order boundary value problems (BVPs) has a great importance because of their applications in fluid dynamics, aerodynamics, astrophysics, nuclear reactions, rocket science etc. The purpose of this paper is to develop two computational methods based on Hermite wavelet and Bernoulli wavelet for the solution of third-order initial/BVPs.

Design/methodology/approach

Because of the presence of singularity and the strong nonlinear nature, most of third-order BVPs do not occupy exact solution. Therefore, numerical techniques play an important role for the solution of such type of third-order BVPs. The proposed methods convert third-order BVPs into a system of algebraic equations, and on solving them, approximate solution is obtained. Finally, the numerical simulation has been done to validate the reliability and accuracy of developed methods.

Findings

This paper discussed the solution of linear, nonlinear, nonlinear singular (Emden–Fowler type) and self-adjoint singularly perturbed singular (generalized Emden–Fowler type) third-order BVPs using wavelets. A comparison of the results of proposed methods with the results of existing methods has been given. The proposed methods give the accuracy up to 19 decimal places as the resolution level is increased.

Originality/value

This paper is one of the first in the literature that investigates the solution of third-order Emden–Fowler-type equations using Bernoulli and Hermite wavelets. This paper also discusses the error bounds of the proposed methods for the stability of approximate solutions.

Abstract

Purpose

The goal of this paper is twofold: (1) to investigate how relatedness-supportive corporate social responsibility (CSR) initiatives influence brand happiness among retail bank customers through a mediating mechanism of customer participation in brand CSR movements; and (2) to analyze how relatedness-supportive CSR initiatives’ effect may be moderated by cause choice and customer-brand goal congruence.

Design/methodology/approach

Data were collected from 379 retail bank customers via a paper-and-pencil survey. The hypothesized moderated-mediation effects were tested using Hayes’ (2013) PROCESS (Model 3, Model 4 and Model 7).

Findings

Results show that relatedness-supportive CSR initiatives increase brand happiness among retail bank customers through increasing their participation in brand CSR movements. Furthermore, the use of customer determination in the choice of cause enhances the positive effect of relatedness-supportive CSR initiatives on customer participation in brand CSR movements. Similarly, when customers choose the cause and the customer-brand goal is congruent, the effect of relatedness-supportive CSR initiatives on brand happiness is stronger than when the customer-brand goal is incongruent and cause choice is not aligned.

Originality/value

This research is grounded on the relationship motivation theory (RMT), basic psychological needs theory and self-congruity theory to unpack the relationship between relatedness-supportive CSR programs on brand happiness. Integrating three research streams (i.e. CSR, brand management and retail banking), this study proposes customer participation in brand CSR movements as a novel mechanism and sheds light on how relatedness-supportive CSR interplays with cause choice/customer-brand goal congruence to affect brand happiness among retail bank customers in emerging markets.

Abstract

Purpose

This study aims to examine the research productivity of Pakistan Agricultural Research Council’s (PARC’s) researchers published during 2001–2020 by using scientometric indicators. The study explored the growth and collaborative trends along with authorship and institutional collaborative patterns at the national and international levels.

Design/methodology/approach

The study was conducted in four phases. Firstly, a search strategy was designed to retrieve reliable data sets. During the second phase, data from PARC research was retrieved from Scopus and Web of Science (WoS). In the third phase, the data were combined, and duplications were removed. Finally, the data were analysed using RStudio and VOSviewer.

Findings

The study identified 2,868 research publications from 16 communication channels spanning over the period of 2001–2020. The growth rate varied during the study period and the year 2020 was the most productive year of the organization. Most of the research was produced in multi-authorship and five authors were dominant. Pakistan Journal of Botany was the most preferred and cited source. Moreover, PARC research collaboration with Pakistani researchers was more than their international counterparts.

Research limitations/implications

Like other research, this research has some limitations. For example, this research is based on secondary data extracted from WoS and Scopus databases, world-renowned online academic. However, researchers should keep in mind while interpreting the results of this study. Secondly, the research publications published by PARC researchers during 2001–2020 were considered. Finally, this research considered English language literature only.

Practical implications

The study’s key theoretical contribution is its strategy for merging WoS and Scopus in RStudio, while its findings could assist agriculture research stakeholders in identifying new areas of research, awards, promotions and identification of research gaps.

Originality/value

To the best of the author’s knowledge, this study is the first to use scientometric indicators to evaluate PARC’s research productivity. This detailed analysis provides a deeper understanding of PARC’s contribution to agriculture research and its potential implications.

Abstract

Purpose

Protean career orientation is a key element that helps explain why workers plan and manage their careers. In the field of nursing, a protean career orientation assists nurses in job search, career mobility and adapting to changing demands. Few studies have explored how nurses’ protean career orientation will lead to job search and how to make better use of the protean career orientation. This study aims to explore how a protean career orientation influences job search via career optimism and the moderating role of mentoring relationships.

Design/methodology/approach

This study conducted a cross-sectional survey of 309 frontline nurses from China. The questionnaire was distributed to nurses through the snowball sampling method. Jamovi 1.2.2 was used for descriptive analysis and Pearson’s correlation analysis. The relationships between the variables and their significance were tested using Process Macro 3.3.

Findings

Results show that protean career orientation was significantly related to career optimism and positively related to job search. Career optimism was significantly related to job search. The indirect effect of protean career orientation on job search through career optimism was significant. The interaction between protean career orientation and mentoring relationships was also significantly related to career optimism.

Originality/value

To the best of the authors’ knowledge, this study is the first to demonstrate how nurses’ flexible career orientation significantly impacted job search through nurses’ career optimism. If nurses work in supportive mentoring relationships, the positive effect of the nurse’s protean career orientation on the job search is decreased.

Abstract

Learning outcomes

After discussing this case, students will be able to understand the challenges faced by social entrepreneurs in starting a health-tech start-up in Africa; create and evaluate lean business models of health-tech companies as a social enterprise; evaluate how health-tech start-ups were developing innovative business models and supply chain networks to make prescription drugs accessible and available in Africa; understand how inorganic growth strategies can help health-tech start-ups scale up; and evaluate what promises investors were seeing while investing in social enterprises in the health-care sector in Africa and what social wealth they were creating.

Case overview/synopsis

In August 2022, Gregory Rockson (Rockson), social entrepreneur and founder of for-profit health technology (health-tech) social enterprise in Ghana, mPharma, stated that he had plans to replicate the company’s business model, which provided people access to drugs and at affordable prices, to other African nations, beyond the company’s existing footprint. However, analysts pointed out that the fragmented drug supply chain and poor regulation in the health-care market across Africa could act as a challenge for mPharma to replicate its business model successfully across the African continent. People in Africa were forced to pay higher prices to buy life-saving drugs due to the continent’s fragmented drug supply chain. To add to their woes, pharmacies struggled to keep life-saving and life-sustaining medicines in stock. Often, patients traveled miles to a pharmacy only to find out that the drugs they needed were not in stock. In addition to this, the markets were flooded with counterfeit drugs. And the Covid-19 pandemic only exacerbated the situation. mPharma managed the prescription drug inventory for pharmacies and drug suppliers using its proprietary vendor management information system. By using the technology infrastructure it had built, the company connected patients, pharmacies and hospitals through a cloud-based software. The system enabled doctors to track in real-time which drugs were available and at which location, thus giving patients reliable access to medicines. Patients registering with mPharma with their prescriptions and medical history received an alert on their mobile phones notifying them where the drugs they needed were available. mPharma bought drugs from major drug manufacturers such as Novartis International AG, Pfizer Inc. (Pfizer) and Bayer AG, on behalf of the pharmacies. This enabled the pharmacies to save on the up-front costs of stocking the drugs, reduced supply constraints and ensured availability of drugs to consumers in these underserved markets. The company had a consignment model wherein member pharmacies had to pay only for what they sold. Most pharmacies forecast the number of drugs they needed and purchased them from mPharma at pre-agreed rates. The company took the inventory liability to prevent pharmacies from going out of stock. As mPharma used its purchasing power to buy drugs in large quantities from drug manufacturers and suppliers, it was able to help patients realize cost savings of 30% to 60% in the purchase of medicines. mPharma was focusing on achieving its ambitious goal of dominating the health-care market in Africa in future. However, analysts felt that the company would face challenges related to poor regulation in the health-care market, high prices of drugs and the fragmented pharmacy retail market in the continent.

Abstract

Purpose

Building on the conservation of resources theory, this research explored the processes underlying the association between perceived workplace incivility and deviant behaviors. Specifically, we tested a mediating mechanism, an interpersonal conflict that has received less consideration in the workplace incivility literature. The authors also tested the organizational climate (i.e. a resource) as a moderator in the perceived workplace incivility–employees’ deviant work behavior relationship.

Design/methodology/approach

Time-lagged research design was followed to explain the relationship of variables. Survey data were collected at time 1 and time 2 from 220 service sector working professionals to test the proposed model.

Findings

The findings suggest that intrapersonal conflict partially mediates the workplace incivility–deviant work behavior relationship. Further, the authors found that the harmful effects of workplace incivility on employees’ deviant work behavior attenuate in the presence of organizational climate as a resource. The results shed light on the beneficial consequences of organizational climate on employees’ work behavior by attenuating workplace incivility and mitigating their deviant work behaviors.

Originality/value

Overall, the study contributed to understanding the mediating role of interpersonal conflict and the moderating role of organizational climate in explaining the workplace incivility–deviant work behavior relationship.

Abstract

Purpose

This paper aims to emphasize economic complexity, tourism, information and communication technology (ICT), renewable energy consumption and foreign direct investment (FDI) as the determinants of carbon emissions.

Design/methodology/approach

These economies rely on the tourism sector, and Asian countries rank among the top tourism economies worldwide in terms of tourism receipts. This study uses a series of empirical estimators, i.e. cross-sectional augmented auto-regression distributive lag and panel cointegration, to validate the main hypotheses.

Findings

The econometric results confirm an inverted U-shaped association between economic complexity and carbon emissions, validating the economic complexity index induced environment Kuznets curve hypothesis for the selected Asian economies.

Research limitations/implications

Finally, the empirical results admit articulating some imperative policy suggestions to attain a sustainable environment on behalf of outcomes.

Practical implications

Furthermore, ICT and renewable energy consumption are environment-friendly indicators, while FDI and the international tourism industry increase environmental pressure in selected countries. In addition, this study also explores the interaction between renewable energy and ICT with FDI and their effects on carbon emissions. Interestingly, both interaction terms positively respond to the environmental correction process.

Originality/value

Because ICT with FDI may not reduce environmental pollution unless the energy used in FDI projects is greener. Moreover, in Asian economies, industrial and other sectors could increase environmental quality via the role of ICT in FDI.

研究设计/方法/途径

这些经济体依赖旅游业, 就旅游收入而言, 亚洲国家在全球旅游经济体中名列前茅。本研究使用一系列经验估计量, 即 CS-ARDL 和面板协整来验证我们的主要假设。

研究目的

本文强调经济复杂性、旅游、信息和通信技术 (ICT)、可再生能源消费和外国直接投资 (FDI) 作为碳排放的决定因素

研究发现

计量经济学结果证实了经济复杂性与碳排放之间的倒 U 型关联, 验证了 ECI 对选定亚洲经济体的环境库兹涅茨曲线 (EKC) 假设。

研究限制/影响

最后, 实证结果承认阐明了一些必要的政策建议, 以代表结果实现可持续环境。

实践意义

此外, 信息通信技术和可再生能源消耗是环境友好型指标, 而外国直接投资和国际旅游业增加了选定国家的环境压力。此外, 本研究还探讨了可再生能源和 ICT 与外国直接投资之间的相互作用及其对碳排放的影响。有趣的是, 这两个交互项都对环境校正过程做出了积极响应。

研究原创性/价值

ICT 与 FDI 可能不会减少环境污染, 除非 FDI 项目中的能源使用更环保。此外, 在亚洲经济体中, 工业和其他部门可以通过 ICT 在 FDI 中的作用提高环境质量。

Abstract

Purpose

The theoretical findings serve as a foundation for further research into understanding sulfide-based solid-state electrolytes, ultimately advancing the progress of all-solid-state batteries.

Design/methodology/approach

The electronic properties of Li7P3S11 are thoroughly explored through first-principles calculations.

Findings

This investigation encompasses the intricate atom-dominated valence and conduction bands, spatial charge density distribution and the breakdown of atom and orbital contributions to van Hove singularities. Additionally, the compound’s wide and discrete energy spectra reflect the substantial variations in bond lengths and its highly anisotropic geometric structure. The complex and nonuniform chemical environment indicates the presence of intricate hopping integrals.

Originality/value

This study provides valuable insights into the critical multiorbital hybridizations occurring in the Li-S and P-S chemical bonds. To validate the theoretical predictions, experimental techniques can be employed. By combining theoretical predictions with experimental data, a comprehensive understanding of the geometric and electronic characteristics of Li7P3S11 can be achieved.

Abstract

Purpose

The purpose of this paper is to empirically examine how different supply chain attributes as determinants of the openness of supply chain affect organizational performance (OP).

Design/methodology/approach

Data were collected from 259 supply chain executives in Pakistan. Structural equation modeling was used to test the hypotheses.

Findings

The findings indicate that organizations may take the selective view of their supply chains resulting in a varying focus on different SC attributes. The results show that though all identified supply chain attributes positively relate to OP, some attributes such as combined agility and cooperation among supply chain partners have a weak correlation coefficient. This indicates that overall the relative openness of supply chain among selected sample of Pakistani organizations is low.

Practical implications

Supply chain executives may not have a selective focus on some attributes; rather, they may consider to have a broader perspective drawing upon a wider range of supply chain attributes as identified in the current study. In order to remain competitive, Pakistani manufacturing organizations need to learn more about opening up their boundaries and enhance the openness of their supply chain.

Originality/value

The contribution of the current study is two folds. First, drawing upon the current literature, it proposes the instrument to measure the relative openness of supply chain. Second, it empirically tests the selected conceptual model which highlights the relevance of supply chain attributes and their role in the resulting relative degree of supply chain openness. The empirical examination of the selected conceptual model of supply chain openness tends to make contribution to the wider literature on supply chain management.
