The purpose of this paper is to analyze differential consumption patterns of Pakistani migrant households resulting from foreign and domestic remittances.

Using the Working-Leser model and a number of matching techniques, the authors analyze a representative household survey carried out in 2010–2011 to compare various expenditure categories of recipient and non-recipient households across different income brackets.

Results show that foreign remittances lead to significant consumption changes. Contrary to the widely held view, remittances do not raise the budget share on consumer goods and recreation, while allocation on education increases substantially. Households receiving domestic remittances also reflect strong focus on human capital with significantly higher shares of health and education. Recipients of international transfers living below one dollar a day spend proportionally more on food compared with their non-recipient counterparts whereas their education and health budget shares are not dissimilar.

The positive effect of remittances on expenditures on human capital coupled with a lack of evidence suggesting an increase in the share of conspicuous spending resulting from remittances highlights the beneficial role that remittances play in a developing country.

Extant literature lacks consensus on whether migrant remittances should be treated as a temporary or permanent source of household income. In this study, the authors argue and empirically show that the two need not be mutually exclusive, and may co-exist depending on the nature of remittances and household characteristics.

The future will see a new revolution in both industry and society in Industry 5.0. Human–robot collaboration and robotic management will be critical components of Industry 5.0. In this revolution, humans and robots will collaborate to improve process efficiency by utilizing human intelligence and innovation. Industry 5.0 creates a powerful framework for modern digital smart factories and manufacturing technologies through complex systems, and it is constructed to interact with powerful computing power, to solve complex problems more efficiently and with less human intervention in this Volatile, Uncertain, Complex, Ambiguous, Radicality, and Rapidity (VUCA-RR) world. To overcome VUCA-RR world, Industry 5.0 involves a combination of human and robotic systems for sustainable development. Managers, practitioners, researchers, and educators are scrambling to understand and implement the method as well as to find best practices toward Industry 5.0. This chapter will draw attention to research and practice topics in the VUCA-RR and business agility development methodology in perspective of Industry 5.0.

The world is changing fast and pace of changes that are being observed since start of the twenty-first century have never been observed before. Due to such changes and their impact, world is described in terms of Volatile, Uncertain, Complex and Ambiguous (VUCA). The trend of industry 4.0 is also said to be an another contributing factor into the VUCA environment. The VUCA creates a lot of challenges for organization from the perspective of management and leadership. Both business and leadership agility are needed more than VUCA as the VUCA world is becoming old. Therefore, the purpose of this research is to review the literature and to summarize the understanding with regard to managing VUCA-RR world in an era of Industry 4.0. Since the advent of term VUCA, many researchers have provided theoretical model and framework to guide managers regarding to their action and strategies. But, current research postulates based upon the literature that agile management’s tools and techniques are highly effective in managing the situation of VUCA-RR in the era of Industry 4.0. The research concludes that Industry 4.0 together with VUCA-RR and indecently possess to change management challenges to organizations. The organization can be in better position to manage change management challenges posed by Industry 4.0 by implementing the agile management. The Industry 4.0 will latter compliment to agile management tools and techniques which will make any organization to become a better equipped to face the VUCA-RR world. The research has also concluded that agile management powered by Industry 4.0 enabling technologies presents enormous opportunity in the form of VUCA 2.0 (Vision, Understanding, Courage, Adoptability, Rapidity and Radicality) that can be used to square off the effect of VUCA-RR world.

This paper aims to systematically review male cosmetics consumption (CC) literature and, given the dearth of research about the topic, especially on Western emerging country contexts, to shed light on the paradoxical behaviour concerning male grooming by empirically assessing the impact of some psychological and demographic antecedents of consumption.

Six hypotheses derived from a systematic review of the literature were tested through structured equation modelling (SEM), based on data of 476 Brazilian men.

The results empirically sustain the positive influence of vanity and masculinity in grooming product consumption, with partial mediation of vanity between masculinity and consumption. Counterintuitively, it also confirms the negative influence of income. Age and marital status are not statistically relevant.

Practitioners should invest in marketing actions focusing on low-income men, who showed genuine interest in grooming products, promoting them as powerful tools to improve appearance and social recognition. Additionally, educational and wellness-related campaigns could be effective.

Beyond profitability, economic growth and men’s well-being, the results might affect the whole society through male cosmetics' contribution to blending gender paradigms.

This study focuses on an economically relevant segment that defies the status quo. It is the first to systematically demonstrate the state of the art of male CC knowledge and to illuminate the role of psychological and demographic variables in influencing CC, enriching the literature on appearance, gender and consumption.

This study aims to introduce a research framework that identifies the potential sources of design self-efficacy that emerge from the digital class by covering the teaching for professional competence model (TPCM) to enhance students’ design self-efficacy.

The multistage and purposive sampling technique is used, and the respondents considered are Malaysian university students. Further, the students who completed the survey included both local and international students so as to capture responses through primary data.

The findings of this research study reveal that design self-efficacy is determined not only by feedback and collaborative learning but also by perceived digital class experience.

Moreover, this study is limited in offering a theoretical framework using the TPCM; therefore, future studies may incorporate Bronfenbrenner’s ecological systems theory and may also use the theory integration approach. Also, in terms of geographic coverage, the current work is limited to an area in Klang Valley. Future studies may be carried out in other parts or regions of the country. Future researchers may also focus on technological self-efficacy to capture the other related factors that may be related.

This study not only contributed to the theoretical extensions but also to practical implications, which would benefit the policymakers of higher education providers in Malaysia.

TPCM components, which are students’ personal characteristics, teaching practices and student’s perceptions of the classroom climate, are mapped into the digital class context as potential sources of design self-efficacy and collectively labelled as digital class experience. To the authors’ knowledge, the digital class environment variable is yet to be tested as a component of TPCM.

The purpose of this paper is to access the present situation of the Pakistani population that suffers from vitamin D deficiency.

A review-based study was conducted based on publications from Pakistan between the years 2008 and 2018. The publications were archived from Pub Med and Google Scholar databases. A total of 18 publications were shortlisted, based on the cutoff values of vitamin D sufficiency, insufficiency and deficiency.

As per the data, 38.5 per cent of the participants were males, 48.7 per cent were females and 12.8 per cent of the studies have not mentioned the genders of the participants. The cumulative results show that 58.17 per cent (95 per cent CI: 52.17, 64.16) of the population is vitamin D-deficient and 26.65 per cent (95 per cent CI: 21.63, 31.66) is insufficient in vitamin D. The highest level of vitamin D deficiency was reported from Sindh (62.15 per cent), followed by Khyber Pakhtunkhwa (60.57 per cent), Punjab (51.75 per cent) and the Federal Capital (49.25 per cent). Moreover, Cochran’s Q test indicated considerable heterogeneity (p = >0.001) with regard to Vitamin D deficiency (VDD) prevalence found among samples from the selected studies.

The present analysis suggests that more than half of the Pakistani population suffers from VDD, which, thus, should be considered as an epidemic and treated likewise.

Alongside the remarkable evolution of cellular communication to 5G networks, significant security and privacy challenges have risen which can affect the widespread adoption of advanced communication technologies. In this context, the purpose of this paper is to examine research within security and privacy for 5G-based systems highlighting contributions made by the research community and identify research trends within different subdomains of 5G security where open issues still exist.

This paper uses a bibliographic approach to review the state-of-the-art in the field of 5G security and is the pioneering effort to investigate 5G security research using this methodology. Specifically, the paper presents a quantitative description of the existing contributions in terms of authors, organizations, and countries. It then presents detailed keyword and co-citation analysis that shows the quantity and pattern of research work in different subfields. Finally, 5G security areas are identified having open challenges for future research work.

The study shows that China leads the world in terms of published research in the field of 5G security with USA and India ranked second and third respectively. Xidian University, China is ranked highest for number of publications and h-index followed by University Oulu and AALTO University Finland. IEEE Access, Sensors and IEEE Internet of Things Journal are the top publication venues in the field of 5G security. Using VOSViewer aided analysis with respect to productivity, research areas and keywords, the authors have identified research trends in 5G security among scientific community whilst highlighting specific challenges which require further efforts.

Existing studies have focused on surveys covering state-of-the art research in secure 5G network (Zhang et al. 2019), physical layer security (Wu et al., 2018), security and privacy of 5G technologies (Khan et al., 2020) and security and privacy challenges when 5G is used in IoT (Sicari et al. 2020). However, our research has revealed no existing bibliometric studies in this area and therefore, to our best knowledge, this paper represents pioneering such effort for security within 5G.

Drawing upon information processing theory (IPT) and natural resource-based view (NRBV), this study analyses the role of social media technologies (SMT) on internal and external environmental collaboration and green innovation (green product, process and managerial innovation).

This study took in-depth empirical research by developing a survey questionnaire to identify the relationship between SMTs, environmental collaboration and green innovation. The respondents of the questionnaire were supply chain professionals working in the manufacturing industry of Pakistan. The survey collected 475 responses, which were tested through PLS-SEM using Smart-PLS.

The study results indicate that SMTs positively influence both internal and external environmental collaboration. Furthermore, internal environmental collaboration (IEC) fosters green products and green managerial innovation. In contrast, external environmental collaboration (EEC) fosters green processes and green managerial innovation. This study has also tested the mediation of IEC and EEC, which shows that both IEC and EEC mediate all the relationships except green process and green product innovation. The results also revealed that innovation capabilities moderate the relationship between environmental collaboration and green innovation.

Though this study has various practical implications, it is not free of limitations. First, the data were collected from Pakistan, and the results may only be compared with other developing countries. Second, few social media platforms have been considered, but they are increasing in numbers and could be used in upcoming studies. Third, green innovation in the context of products, processes and management is considered, but the concept is evolving, and its other indicators can be taken in upcoming studies.

This study addresses the implication of SMTs, environmental collaboration, innovation capabilities and green innovation, which are helpful for managers and policymakers to design policies.

This study provides the seminal operationalization of SMTs in environmental collaboration and green innovation. This study emphasizes innovation capabilities that firms should adopt.

The objective of the study is to explore the determinants of savings and their relative importance in Saudi Arabia.

The stationarity of the data has been tested using augmented Dickey–Fuller (ADF) tests. Autoregressive distributed lag (ARDL) technique has been applied to establish the long run and short run relationships. Stability of savings function has been tested by applying CUSUM and CUSUMSQ techniques.

Results of ARDL identify the important factors affecting savings behaviour in Saudi Arabia. According to the results, the growth rate of GDP, the interest rate, foreign direct investment (FDI) and budget surplus positively affect savings with the last two having the most influence on domestic savings. The coefficient of the dependency ratio is negative in conformity with the theory. Similarly, the coefficient of the inflation rate is also negative.

There is limited availability of data since only 41 years’ annual data are available.

In the light of the results, it is recommended that in order to increase savings, the government should adopt policies to attract FDI, increase the GDP growth rate and decrease the dependency ratio and inflation.

Government needs to discourage larger family sizes to encourage savings in the light of the result of negative impact of the dependency ratio on savings. In order to decrease the dependency ratio, more family members especially women should be encouraged to participate in the labour market.

There is a scarcity of research for Saudi Arabia on the critical issue of determinants of domestic savings. This is a pioneering study exploring important determinants of savings in Saudi data.
