Abstract
Purpose
This paper aims to examine the dynamic conditional correlation (DCC) and hedging ratios between Dow Jones markets and oil, gold and bitcoin. Using daily data, including the COVID-19 pandemic and the Russia–Ukraine war. We employ the DCC-generalized autoregressive conditional heteroskedasticity (GARCH) and asymmetric DCC (ADCC)-GARCH models.
Design/methodology/approach
DCC-GARCH and ADCC-GARCH models.
Findings
The most of DCCs among market pairs are positive during COVID-19 period, implying the existence of volatility spillovers (Contagion-effects). This implies the lack of additional economic gains of diversification. So, COVID-19 represents a systematic risk that resists diversification. However, during the Russia–Ukraine war the DCCs are negative for most pairs that include Oil and Gold, implying investors may benefit from portfolio-diversification. Our hedging analysis carries significant implications for investors seeking higher returns while hedging their Dow Jones portfolios: keeping their portfolios unhedged is better than hedging them. This is because Islamic stocks have the ability to mitigate risks.
Originality/value
Our paper may make a valuable contribution to the existing literature by examining the hedging of financial assets, including both conventional and Islamic assets, during periods of stability and crisis, such as the COVID-19 pandemic and the Russia–Ukraine war.

Abstract
Scholars have found that transnational migrant women fulfill their role of mothers despite geographical distances. Researchers, however, focus on women in their country of destination, and thus have neglected to look at the experiences of women who get “stuck” in transit countries during their migration journeys. This chapter fills that gap in the literature by examining the experiences of Sub-Saharan African women in Morocco en route to Europe. Interviews with 20 Sub-Saharan African women show that unlike transnational mothers in their country of destination, which are mostly more affluent nations, these women neither have the financial means to provide for their children nor can maintain their relationships with them via telecommunication. Although the women acknowledge that they cannot fulfill their role of mothers in Morocco, they maintain a sense of themselves as mothers by emphasizing that they will financially provide for their children once they reach Europe.

Abstract
Purpose
Recent scholarship has highlighted the complexity of buyer-seller relationships in emerging markets and called for a better understanding of the cultural norms shaping such relationships. This paper aims to draw on social capital theory to explore the role of networks and relational norms, such as wasta, in Arab culture on consumer relational behaviors. The Arab market constitutes a significant economy and social networks and relational norms are of significant value in Arab culture.
Design/methodology/approach
A qualitative approach was used to address the research questions. In-depth semi-structured interviews were conducted with 19 male and female consumers across Lebanon over a four-month period.
Findings
Social networks are heavily used in relational behaviors to achieve four types of goals, namely, self-serving goals, unity goals and equality goals and relationship maintenance goals. In fulfilling these goals consumers create economies of favors that aim at the using and maintenance of communal bonds.
Research limitations/implications
This study was conducted in one geographical context. While Lebanon shares many of its characteristics with other Arab countries, future research should aim at exploring the influence of social networks in other Arab and emerging market contexts.
Practical implications
Consumers have different motivations between formal and informal markets. The research suggests that small sellers in highly embedded markets need to use their social networks and to make their stories authentic and known within their communities to facilitate emotional connections with consumers.
Originality/value
Emerging markets offer opportunities to extend our understanding of marketing theory and practice. This research provides a richer understanding of Arab consumers and suggests that wasta relationships play a role in consumptive decisions and not just in business negotiations. Wasta, as a cultural form of cultural capital, is heavily used in consumption as a coping mechanism to overcome market inefficiencies.

Abstract
Purpose: In this chapter of this book, the role and contributions of blockchain in Industry 5.0 are examined. Especially, the advantages offered by blockchain in mass customization, hyper-personalization, human–robot collaboration and cognitive systems, which constitute the main theme of Industry 5.0, are mentioned.
Need for the study: With developing technology, revolutions are taking place in the industry. While these revolutions are occurring, various technologies serve as enablers. In this chapter, one of these technologies, blockchain, is examined.
Methodology: Industrial revolutions represent important technological developments for societies. In this chapter, Industry 5.0, one of these revolutions, is discussed. In the first section, the main themes of Industry 5.0 were examined. Afterward, the transition from Industry 4.0 to Industry 5.0 was analyzed. Then, the opportunities offered by Industry 5.0 were reviewed. Subsequently, the contributions of blockchain to Industry 5.0 were examined. Finally, the role of blockchain in Industry 5.0 is summarized.
Findings: The main themes of Industry 5.0 enable customized processes and smart production approaches. Blockchain makes significant contributions to these processes with its security and traceability features. In addition, smart contracts can increase transparency, traceability and security among stakeholders in the production process with their distributed ledger structure and immutability features. In blockchain networks, each transaction is carried out and approved by consensus. This consensus, provided by smart contracts, also secures transactions by reducing administrative costs. With these contributions, blockchain meets the security and smart management requirements of Industry 5.0.

Abstract
Purpose
The purpose of this paper is to explore the experiences of a refugee family navigating complex disability and restrictive practice service systems. Living with disability, or caring for someone with disability can compound the disadvantage and marginalisation already experienced by refugees. The nexus between disability and refugee status, particularly intellectual disability and restrictive practices, has received little scholarly attention and almost nothing is known of people’s experiences in this situation.
Design/methodology/approach
Thematic analysis of a case study is used to illustrate the experiences of a refugee family in this situation. The case study presented was part of a larger ethnographic study exploring the experiences of people of refugee background living with disability.
Findings
There were numerous barriers to accessing appropriate services. The family experienced high levels of stress simultaneously navigating the resettlement process and the disability service system. They were poorly informed and disempowered regarding the care of their loved one and the use of restrictive practices. Experiences in the country of origin, employment responsibilities, and unfamiliarity with the service system were key factors in this family’s difficulty in safeguarding the rights of their family member with disability.
Originality/value
This case study examines the complexity experienced when disability intersects with refugee background. Areas for additional research and significant gaps in service provision are identified. The case study clearly demonstrates the importance of understanding people’s pre- and post-settlement experiences to inform policy and service provision.

Abstract
Communications professor, Norman Denzin, describes interactional moments that create potentially transformational experiences as epiphanies, which are subdivided into the major, the minor, the cumulative, the illuminative, and the relived. In his paradigm for the examination of racialized identity formation, psychologist William Cross offers a Nigrescence Model with a four-stage approach to understand the development of Black racial identity. Cross’ model has been modified to assess other aspects of identity formation such as gender consciousness. My story illuminates how the convergence of these theories offers a new lens through which to view the maturation of raced and gendered subjectivities. This performance text uses an Africana feminism performance pedagogy rooted in Yoruba feminist philosophy to expose the reproductive violence perpetuated against Black women and recover the healing, generative force of female power.

Abstract
Purpose
The purpose of this paper is to provide knowledge on barriers to preventive action on early childhood overweight in non-western migrant families. It investigates the underlying understandings of the parental role in relation to weight control present in health-care professionals and in families.
Design/methodology/approach
The study is based on qualitative interviews with parents who are engaged in interventions aimed at helping them and their children to adopt a healthier life style, and on interviews with health-care professionals.
Findings
This study shows that the participating parents, all low SES and living under different forms of insecurity, perceived their parental task for the present as creating well-being for their children, and they were, therefore, reluctant to enforce dietary changes. The health-care professionals, in contrast, considered the need for change through a perspective on future risks.
Research limitations/implications
The results are based on a rather small sample and the link between insecurity, family dynamics and health practice needs further research.
Originality/value
The participating parents represented a group that is rarely included in scientific research and the study, therefore, contributes valuable knowledge on health behavior in ethnic minority families. The empirical analysis provides new insights for health professionals regarding the suitability of the universal model of parental feeding styles. It illuminates the implications of implicitly applying this model in health interventions which involve vulnerable categories of parents such as refugees to western societies.

Abstract
Telling a story is an essential tool for being human. Storytelling has been described as an aspect of the social self that helps shape relationships through the power of words. This chapter examines the role of digital personal narratives in the schooling of middle grades English language learners (ELLs) in one middle school in a rural, Northeast state. The ELL students, their teacher, and the author engaged in a digital story project, which was part of a literacy unit that took place over a period of six months in an intermediate English classroom of 14 students. Using the This I Believe (TIB) national curriculum that focuses on the core values that guide daily lives, the ELL students narrated their own stories. The author argues for the use of such stories in institutions where the preparation of future professionals, such as teachers, social workers, and counselors grapple with the meaning of cultural competency skills and its implications for their fields. How might such institutions embrace and integrate more student voices? How might such stories inform pedagogy? As a result of the project, the author developed a model that could utilize these digital narratives to develop cultural competency in a preservice teacher education program. Such stories could become part of a larger agenda of meaningful activities for preservice teachers related to the areas of (1) digital storytelling, (2) response to literature, (3) service learning and research, and (4) critical reflection.

Abstract
This chapter is structured for teaching young learners with physical (orthopedic) disabilities in special education. Orthopedic impairments encompass a range of disabling conditions. Orthopedic impairments are typically grouped into three main categories: (1) congenital anomalies (CA) such as absence of a member or clubfoot, (2) impairments caused by disease such as bone tuberculosis (TB) or poliomyelitis, or (3) impairments for other causes to include amputations, fractures, cerebral palsy (CP), burns, or fractures. In the chapter, the authors present definitions of various orthopedic impairments and discuss their respective etiologies followed by discussions of specific disabling conditions. Students with orthopedic impairments present both challenges and opportunities to special education teachers as is evident in the following case of Amira, a girl with asthma and CP.

Abstract
Purpose
The paper investigates an unusual form of social enterprising located in a poor region of Pakistan. The purpose of this paper is to examine a novel form of micro social enterprise. Their form and functions are considered, examining how they conform to what is expected of a social enterprise. The extreme cases are analysed to reflect on what constitutes the explanatory characteristics of a social enterprise.
Design/methodology/approach
Information on examples of micro social entrepreneurship was collected from the troubled context of Khyber Pakhtunkhwa, a very poor region of Pakistan. Using the constant comparison method, explanatory themes of structure and practice are drawn out.
Findings
These enterprising social agents were engaged in opening up an opportunity space for those disadvantaged by the context. Driven by a strong sense of community responsibility, they drew upon limited, but culturally available resources. Relevance, embeddedness and informality were identified as structural characteristics, and bricolage and effectuation, frugality and social responsibility emerged as practices. Not only did context shape what they did and how they did it, but the purpose of these enterprises was also to help reshape context. From this analysis, it is argued that conceptual concerns should be directed towards behaviours; it should be asked how are enterprises agents of social change, and how are they enterprising?
Research limitations/implications
It is argued that a robust indicator for social enterprise is not what they are, but what they do. Consequently, for understanding and theorising, it is suggested that the focus remain on enterprising. This study was limited to unusual cases which may be atypical and ungeneralisable. Nonetheless, the concept – enterprising – may have theoretical applications.
Social implications
In reviewing the analysis and findings, it is noted that the proposals in the paper may comprise the early stages of a theory of social entrepreneurship practice. There may be considerable explanatory power in examining the interplays between the agency of social enterprises and the structures that are constituted in the formal and informal institutions with whom they interact.
Originality/value
Descriptively, the account draws attention to a possibly neglected phenomenon. Moreover, the extreme cases draw out the significance of a localised practice. Conceptually, there may be value in prioritising practice in social enterprise rather than form and structure.
