The present study aims to bring out the impact of consanguinity on spontaneous pregnancy loss (SPL) and on descendants’ health, among the population of north Morocco.

Convenience sampling was used for collecting data. A questionnaire was randomly administered to 385 couples represented by either the husband, the wife or both. The study lasted for three months, from January to March 2015.

In total, 238 valid questionnaires were analysed. The results showed that the consanguinity rate was 45.23% and that most consanguineous unions were between first cousins (91%). Data analysis revealed that SPL risk was similar in consanguineous and non-consanguineous couples (OR = 1.6; IC95% = 0.9–2.9). Also, no significant difference was observed in terms of SPL type (OR = 1.6; IC95% = 0.7–3.9) and frequency (p = 0.81). However, late SPL frequency was significantly lower in consanguineous couples (p < 0.001), whereas no significant difference was registered in terms of early SPL frequency (p = 0.73). On the other hand, consanguineous couples displayed a significantly higher risk of descendants’ health disorders in comparison with non-consanguineous ones. Moreover, the consanguineous couples had a significantly higher number of children with health disorders (p < 0.001). The risk analysis also showed that consanguineous couples displayed a significantly higher risk of congenital malformations (OR = 7.23; IC95% = 3.52–14.84) and multifactorial diseases (OR = 3.72; IC95% = 1.46–9.49), but no significant difference was observed in terms of behavioural disorders risk.

The population awareness regarding the negative effects of consanguinity should be raised through education programmes and premarital, prenatal and genetic counselling services.

The practice of consanguinity has been culturally preferred in most Arab countries, including Morocco. This behavior leads to an increase in genetic abnormalities, such as hypertension and diabetes. This paper examines the prevalence and determinants of first-cousin marriages and their impact on diabetes among offspring.

Data on 882 couples were collected through face-to-face interview via a pre-established questionnaire based on the variables selected within the objectives of this study. The authors used the multiple logistic regression modeling procedure in this study.

The results of the study indicate that the prevalence of first-cousin marriages were 15% among students’ parents. From the multiple logistic regression modeling, the authors found a significant effect of paternal and maternal grandparents’ first-cousins marriage on that of parents (aOR = 3.27 and aOR = 3.36, respectively). However, an 11-fold higher risk of first relative marriages among parents once the paternal and maternal grandparents were first-cousins and the father was illiterate (aOR = 11.01). Moreover, the authors reported a diabetes risk of more than 14 times when the effects of first-cousin maternal grandparents and parents and the hypertension among mother or her sibling were combined (aOR = 14.48) or when the effects of first-cousins maternal grandparents, first-cousin parents and mother’s age at marriage between 21 and 29 years were combined (aOR = 14.56).

First-cousin marriage depends on the father’s illiteracy and the consanguinity of grandparents’ factors. The cumulative effect of first-cousin marriage among grandparents, parents and a family history of hypertension among mother or her sibling increase the risk of diabetes among these mothers.

ß-thalassemia is a hereditary disorder due to mutation in the ß-globin gene on chromosome 11. Out of 200 known ß-globin gene chain mutations recognized, it is better to identify the most common mutation in specific regions and ethnicity for cost-effective molecular diagnosis of this disorder. Therefore, this study aims to practice multiplex-amplification refractory mutation system (ARMS) PCR on patients with thalassemia in Khyber Pakhtunkhwa (KP) to investigate the most common mutations in the ß-globin chain gene.

Twenty-two individuals (patients, their parents and non-affected siblings) with signed consent were studied from six consanguineous families of ß-thalassemia. Blood samples were collected for DNA isolation. For the detection of mutations in the ß-globin gene, ARMS-PCR was used. The amplicon was visualized through 2% Agarose Gel.

The most common mutations among different ethnic groups in the study area residents were Fr 8-9 (+G) and IVS 1-5 (G> C). The prominent enhancing factors for ß-thalassemia are inter-family marriages and lack of awareness.

Multiplex ARMS_PCR is the most valuable technique for assessing multiple mutations in a single reaction tube.

Due to extensively found ethnic and regional variations and a high rate of consanguinity, the Pashtun population has a great risk of mutations in their genome. Therefore, ARMS-PCR is a cost-effective mutational diagnostic strategy that can help to control disease burden.

Limited studies using ARMS-PCR for mutational analysis in the ß-globin gene are conducted. This study is unique as it targeted consanguineous families of KP Pakistan.

The literature on ‘mixed’ families (in which members are socially viewed as ‘different’ due to their varying ethnicities and/or nationalities) identifies several stakes of mixedness. One of them arises from childbirth, after which parents need to give name(s) to their offspring. How does the parent–child dyad understand the giving of names in their mixed family? What does naming children unveil regarding interpersonal interactions and the value of children within this social unit? The chapter delves into these questions through a case study of forenaming children in Filipino-Belgian families in Belgium. Interview data analysis reveals two modes of forenaming in these families: individualisation through single forenames and reinforcement of collective affiliation through compound forenames. Through the analytical framework of social relatedness, this chapter uncovers the way the act of naming a child bridges families based on biological and social ties, generations, and parents' nations of belonging in their transnational spaces. The complex process of naming reflects the power dynamics not only within the parental couple but also within the wider set of social relations. Although the use of forename(s) in everyday life and in legal terms differ, the value of children in the mixed families studied lies in their symbolic role as social bridges linking generations and non-biological relationships, the then and now, and the here and there.

Livelihood preference for children is anchored in the aspiration of parents for a better life for them with due consideration of their capacities given available resources and opportunities from inside and outside the community. Given the data from an earlier survey I conducted, this chapter examines the fisheries management issues as contexts and the time factors that may have influenced the livelihood preference for children of parents, primarily fathers. Twenty-five percent of parents or 30 out of the 120 non-probability samples of municipal fishing families surveyed in South Negros in the Philippines preferred fishing for their children. For a comparative analysis, 30 parents were also randomly drawn from the remaining samples who preferred other livelihoods for their children away from fishing. As a male-dominated industry, evident in the fishing history of families, the tradition may have already declined among most parents as non-fishing livelihoods were perceived to offer family resilience to ecological and socioeconomic changes. The projected decrease in new families engaged in fishing would also mean a pressure reduction on municipal fisheries; thus, opportunities for non-fishing livelihoods must be accessible through full scholarships for college or technical-vocational education. Meanwhile, basic education sciences should infuse lessons in responsible or right fishing practices to expose children to sustainable fisheries at a young age if they pursue fishing livelihoods when they become adults.

This research aims to analyze, from the perspective of family life trajectories, the intergenerational changes in the reproductive strategies of Costa Rican households. The four strategies explored are fertility and marriage, educational, economic, social and symbolic. Pierre Bourdieu’s theory of social reproduction strategies is the frame of reference to study these strategies. Also, the second demographic transition (SDT) is used to contextualize intergenerational changes. The family life trajectories of three generations in different geographic locations and socioeconomic contexts were reconstructed through interviews. A generational triad was chosen for the interviews; the generational triad refers to three generations of the same consanguineous family. One interview was conducted per generation in each triad, 3 per triad, and 15 in total. Generationally, changes in the types and forms of households are identified; they are dynamic households that change their composition as part of the kinship and family support networks undertaken. The first generation with a single marriage, secondary economic role, not least, but within the priority household. Second generations of one or more unions, in the cases of second unions, unlike the first ones, are unions with shared responsibilities. And the third generation with an independent life, living in an apartment with roommates, or who at their parents’ age still live in the dwelling with them, at ages when they already had families and independent life. Finally, this work seeks to discuss whether the dynamics of household transformations are influenced by the socioeconomic context of each household and each generation.

This chapter is born out of concern about the perception of the physical and symbolic place of the live-in housekeeper, both in socioeconomic, and historical terms, as well as the architectural and social dynamics of the home. An intersectional and teleological analysis of the intrinsic devaluation of paid social reproduction work is carried out, based mainly on gender, race, and class inequalities. Ultimately, the chapter tries to locate the position in which the maid finds herself in the domestic environment, both in family relationships and in the symbolism inherent to the concept of the maid’s room. Based on sociological, philosophical, and anthropological analysis, the ambiguous place of domestic workers becomes clearer, promoting a reflection on the very concept of family and household. Thus, the chapter proposes to achieve a hermeneutic dive into the experience of this working class, revealing a hierarchical system beyond the socioeconomic, but above all, of their subjectivities.

This study aims to identify various factors that have driven the knowledge transfer process for succession purposes in family business since the 1920s and discuss their implications for advancing effective succession planning in this business sector for the next 100 years.

The paper reviews and synthesizes current research on knowledge transfer drivers in family business from 1923 to 2023 and draws out future perspectives on what will influence the knowledge-transferring process in the next 100 years.

Trust, organizational culture and environmental factors such as the need to create competitive advantages, technological advancement and new sources of knowledge have been identified as the most prominent drivers of knowledge transfer for effective succession in family business throughout the 1920–2020s. In the future, the ability to create value, the internationalization process and business innovations will play an essential role in knowledge-sharing among family and non-family members during succession.

The paper provides a review of past development and a future perspective on factors enhancing the effectiveness of knowledge transfer for succession in family firms.

This paper aims to analyze how psychosocial support influences caring activities toward indigenous older adults.

A descriptive study with the participation of 229 informal indigenous caregivers. The study considered both sociodemographic and medical variables. It used the mini-mental test to determine the cognitive level in the elderly. It applied the Yesavage and Zarit scales to establish depressive symptomatology and caregiver burden. Finally, the study used the MOS psychosocial support and Apgar screening questionnaires to assess the psychosocial dimension and the patient’s family functional state, respectively.

The study observed a low caregiver burden effect using the MOS questionnaire. This may be explained due to variability in the Zarit Scale Score product of other variables like years of care (−0.17 and −0.28), depressive symptoms (0.16 and 0.18), cognitive level (mini-mental) (−0.13 and −0.14) and comorbidity (0.26 and −0.27). The study obtained an incidence between (−0.02 and −0.12) when including all assessed dimensions into the model. The instrumental dimension in the social support questionnaire obtained the highest score.

Protective factors prevail in the group of indigenous caregivers allowing this activity to not trigger overload. Yet, variables such as the female gender, some comorbidities and the presence of depressive symptoms could be potential variables for dysfunction in this occupational role.
