Lean (TQM and JIT) and agile manufacturing (AM) are viewed as strategic capabilities that can help firms to meet diverse set of market demands. However, the question whether lean manufacturing and AM are complementary or competing capabilities is still open to discussion. This research proposes an integrated research framework that draws on complementary theory, theory of systems, and concept of fit to examine this question regarding these two strategic capabilities.

Data are collected from 248 apparel exporting firms, and the proposed model is evaluated using structural equation modeling.

Results show that lean manufacturing, AM, and supporting management and infrastructural practices have positive and complementary effects on firm's performance. Further, results depict that lean manufacturing and AM complementarity is a complete organizational synergistic phenomenon, and piecemeal implementation of these initiatives may lead to suboptimal or unsatisfactory results. Results also indicate that there is no significant direct (correlated and uncorrelated) relationship of management, infrastructure, lean manufacturing, and AM practices with firm's performance and support that lean manufacturing and AM are not competing paradigms.

This research is based on cross-sectional data from one industry. Future research should collect data from diverse sectors in different countries.

This study provides a key insight for manufacturing managers that piecemeal implementation of lean manufacturing and AM does not yield optimal outcomes. In addition, study suggests that lean manufacturing and AM complementarity builds on strong foundation of strategic management and internal and external infrastructure. Therefore, managers should focus on development of skilled and empowered human resources, technological advancements, and learning and virtually integrated organizations for effective implementation of lean manufacturing and AM.

Proposed framework is one of the first, if not the first, that seeks to resolve the question: whether lean manufacturing and AM are complementary or competing capabilities. Complementary effects of lean manufacturing and AM along with management, internal infrastructure, and common external infrastructure practices have positive impact on performance. This study also segregated infrastructure practices into internal and common external infrastructure practices.

Saudi Vision 2030 is centred around innovation, entrepreneurship and women’s empowerment to foster economic growth and bring about social change. In this context, this study examines the impact of product innovation on the success of women entrepreneurs in Saudi Arabia, who constitute around 42% of the population and experience empowerment through recent reforms. Additionally, the study explores the moderating effect of risk-taking behaviour and the mediating role of perseverance.

Employing a quantitative design, this study collected data from 256 Saudi women entrepreneurs from five major cities using a snowball sampling technique. The data were gathered through a survey questionnaire and analysed in SmartPLS 4.

The results revealed that product innovation positively impacts both entrepreneurial perseverance and women’s entrepreneurial success. Furthermore, the moderating role of risk-taking behaviour and the mediating role of perseverance were found to be statistically significant in the relationship between product innovation and women’s entrepreneurial success.

The research findings help policymakers to focus on important factors that can harness women’s entrepreneurship. The Saudi government and society should offer increased financial, regulatory and moral support to women entrepreneurs to achieve the National Vision 2030.

This research provides empirical evidence on the crucial topic of women’s entrepreneurship in the context of Saudi Arabia, specifically from the perspective of product innovation, risk-taking behaviour and perseverance. The findings provide important practical, social and regulatory implications for various stakeholders.

Mismanagement and corruption in disaster relief operations (DROs) have created a demand for transparency and visibility in humanitarian logistics and supply chains. The global relief organisations and recent research endorse the adoption of digital solutions in DROs. The purpose of this research is to examine the moderating role of digitalisation in enhancing transparency in humanitarian logistics and supply chains of DROs in Pakistan.

Employing the quantitative research method, the data were collected from 340 disaster relief workers through survey questionnaires using the snowball sampling technique. The data were analysed in the SmartPLS3 software of PLS-SEM.

The findings suggested that in Pakistan, where corruption and mismanagement in humanitarian logistics and supply chain have been the greatest concerns of all the stakeholders, digitalisation of the DROs is a way forward to create transparency in the system and build the trust of the donor organisations and public.

The sample included only 340 disaster relief workers, future researchers may test the proposed model on a larger sample size and from different stakeholders' perspectives such as the disaster victims, government agencies and NGOs.

The ultimate beneficiaries of a digitalised and transparent humanitarian logistics and supply chain will be the society as a whole and particularly the victims of the disasters. By adopting the appropriate technologies in DROs, the victims will receive timely and entitled resources, and early warnings will save many lives.

The paper contributes to the body of knowledge by providing the first empirical evidence of examining the moderating role of digitalisation in creating transparency in humanitarian logistics from one of the top ten most disaster-affected nations.

The purpose of this study is to provide further evidence on the importance of international diversification, and to determine the optimal allocation of assets in a portfolio comprising domestic (Australian) and international assets. The study focuses on stock index futures contracts in five countries ‐ Australia, USA, UK, Hong Kong and Japan. Daily data for the five selected contracts over the period from 1 January 1990 to 31 December 2000 is employed in the study. Consistent with previous studies, the results confirm the importance of international diversification and indicate that the portfolio risk is reduced considerably when more international assets are added sequentially to the portfolio. Empirical analysis also shows that the optimal asset allocation results in higher risk reduction and better returns when compared with an equally weighted portfolio.

This study examines the drivers of consumers’ intentions to adopt mobile wallets in Pakistan’s hospitality industry. Specifically, it proposes and tests a model of non-user consumer intention to adopt mobile wallets for hospitality in Pakistan.

A conceptual framework grounded in the mobile technology acceptance model (MTAM) integrating personal innovativeness in IT, mobile perceived compatibility, perceived critical mass, perceived enjoyment, mobile perceived risk and mobile perceived wireless trust was used as a theoretical model of the study. Using structural equation modeling, we tested the research model and its relevant hypotheses on a sample of 310 mobile wallet nonusers.

Findings from the expanded model demonstrate that only four of the suggested hypotheses were insignificant in this study and require additional examination. Overall, the modified model explained 63% of the variance in the behavioral intention to adopt mobile wallets. This paper concludes with key implications and directions for future work concerning the limitations of this study.

This study contributes to a theoretical understanding of the factors that explain nonusers’ behavioral intention to use a mobile wallet in the hospitality context.

The purpose of this paper is to examine the role of volunteers and its impact on related accountability practices towards beneficiaries by a large humanitarian non-governmental organisation (NGO) in Indonesia.

The authors adopted a qualitative case study design. The empirical evidence comes from rich fieldwork carried out in an Indonesian NGO. The authors collected the evidence mainly via 46 interviews and five focus groups.

The authors found that the case NGO drew heavily on the social and cultural capitals of volunteers in the process of serving its beneficiaries, which, in turn, facilitated the enhancement of its accountability to the beneficiaries. The authors also found that volunteers play a bridging role to reduce the distance between NGOs and beneficiaries.

For NGO managers, this study provides necessary empirical evidence on the positive role played by the volunteers in the development and operationalisation of accountability to the beneficiaries. In the authors’ case, beneficiary accountability is enhanced by the social conduct and practices performed by the NGO’s numerous volunteers. Beneficiary accountability is of significant concern to the policy makers too. This study shows that volunteers and NGO can work in a reciprocal relationship where social and cultural capital can be mobilised to each other’s advantage. To facilitate beneficiary accountability, NGOs can draw on the socio-cultural capitals held by the volunteers who appear to share the same norms and expectations with the beneficiaries. This process can also lead to the building of social and cultural capital by the volunteers themselves as they achieve great satisfaction and gain valuable experience in this process that could lead to greater satisfaction in their spiritual and material lives.

The authors extend the previous literature on beneficiary accountability by highlighting the under-researched role of volunteers in such accountability practices. In this paper, the authors first discuss the facilitating role of volunteers in enhancing NGOs’ accountability towards beneficiaries. Then, this is illustrated empirically. In addition, the authors argue that although Bourdieusian concepts like field and capital have been widely used in the analysis of various organisational practices the concept of habitus received limited attention particularly from the context of developing countries. The authors undertake an examination of the habitus of volunteers in the Indonesian case organisation and explore their linkages with the field and associated capitals.

The purpose of this research is to provide the necessarily and resourceful information regarding range sensors to select the best fit sensor for robust autonomous navigation. Autonomous navigation is an emerging segment in the field of mobile robot in which the mobile robot navigates in the environment with high level of autonomy by lacking human interactions. Sensor-based perception is a prevailing aspect in the autonomous navigation of mobile robot along with localization and path planning. Various range sensors are used to get the efficient perception of the environment, but selecting the best-fit sensor to solve the navigation problem is still a vital assignment.

Autonomous navigation relies on the sensory information of various sensors, and each sensor relies on various operational parameters/characteristic for the reliable functioning. A simple strategy shown in this proposed study to select the best-fit sensor based on various parameters such as environment, 2 D/3D navigation, accuracy, speed, environmental conditions, etc. for the reliable autonomous navigation of a mobile robot.

This paper provides a comparative analysis for the diverse range sensors used in mobile robotics with respect to various aspects such as accuracy, computational load, 2D/3D navigation, environmental conditions, etc. to opt the best-fit sensors for achieving robust navigation of autonomous mobile robot.

This paper provides a straightforward platform for the researchers to select the best range sensor for the diverse robotics application.

The presence of heavy metals in milk causes many acute and chronic physiological dysfunctions in human organs. The present study aims to investigate the heavy metals in cow's and buffalo's milk of two major cities, Karachi and Gujranwala, Pakistan to estimate metal intake by humans from this source.

In total, 48 milk samples from 2 cities were drawn from animals' udder to avoid contamination. Each sample was digested with nitric acid at 105 ^oC (degree Celsius) on a pre-heated electric hot plate to investigate the metals by atomic absorption spectroscopy (flame type). Air-acetylene technique analyzed chromium, cadmium and lead, and the hydride method analyzed arsenic in the milk samples.

The results revealed the highest mean lead concentration (19.65 ± 43.86 ppb) in the milk samples, followed by chromium (2.10 ± 2.33 ppb) and arsenic (0.48 ± 0.73 ppb). Cadmium was not detected in any sample, assuming cadmium's occurrence was below the detection level. The concentrations of all the metals in the samples of the two cities do not differ statistically. Lead concentrations in the buffalo's milk were higher than in cow's milk (p < 0.05). However, the concentrations of arsenic and chromium between buffalo's and cow's milk do not differ statistically. The present study reveals a lower level of metals in the milk than those conducted elsewhere. The mean concentrations of all the metals met the World Health Organization's (WHO) safety guidelines (1993).

Although cadmium causes toxicity in the human body, cadmium could not be measured because cadmium's concentration was below the detection level, which is 1 ppb.

This study will help reduce the toxic metals in our environment, and the sources of heavy metals, particularly from the industrial sector could be identified. The feed and water consumed by the milking animals could be carefully used for feeding them.

This study will help reduce the diseases and malfunction of human organs and organ systems since these heavy metals cause toxicity and carcinogenicity in humans. Arsenic and chromium cause cancer while lead causes encephalopathy (a brain disease).

The study reports heavy metal concentrations in the two attributes of four independent variables of raw milk samples that were scarcely reported from Pakistan.
