Challenges and Opportunities of Biologically Active Peptides in the Design and Formulation of Nutraceuticals and Functional Foods
Authors: Arranz Elena , Fernández-Tomé Samuel , Hernández-Ledesma Blanca
Published: May 2023

Consumer demand for products with health benefits beyond simple nutrition
is the market driver for nutraceuticals and functional foods. The development of these
products has been on the rise since the last decade as consumers became more aware of
the consequences of lifestyle diseases. This scenario has also benefited from the
growing economy, changing lifestyles and consumption patterns. Researchers and the
food industry are exploring novel sources of bioactive components and attention has
been given to underutilized grain proteins. This chapter aims to review the
incorporation of underutilized grains into nutraceuticals and functional foods. The
recent advances and challenges in food processing techniques to develop these products
are presented. Moreover, comprehensive details on the improvement of product
properties with the incorporation of underutilized grains, by means of nutritional,
techno-functional and bioactivity, as well as sensorial analysis are given. Finally, the
health promoting effects of peptides encrypted in the protein fraction of these grains
will be discussed. 
Challenges and Opportunities of Biologically Active Peptides in the Design and Formulation of Cosmeceuticals
Authors: Alcántara-Quintana Luz Eugenia
Published: May 2023

In recent years, the use of cosmetics and personal care products has
increased worldwide, due to their corrective, decorative and hygienic functions. The
development of new cosmetic formulations based on the use of bioactive compounds
has expanded rapidly due to consumer demand for products with protective and
therapeutic functions derived from natural sources. Skin aging is a complex biological
process influenced by a combination of endogenous or intrinsic and exogenous or
extrinsic factors. Since skin health and beauty are considered to be one of the main
factors representing overall “well-being” and the perception of “health” in humans,
several antiaging strategies have been developed in recent years. There are two main
groups of agents that can be used as antiaging components, antioxidants and cellular
regulators. Antioxidants, such as vitamins, polyphenols and flavonoids, reduce collagen
degradation by reducing the concentration of free radicals in tissues. Cell regulators,
such as retinols, peptides and growth factors, have direct effects on collagen
metabolism and influence collagen synthesis.
Biomaterials Applied to Medical Devices and Pharmacy
Authors: Ngo Tri-Dung
Published: May 2023

Biomaterials have been utilized in healthcare applications a number of
times. Nowadays, subsequent evolution and the increase in the life expectancy of
world’s population have made biomaterials more attractive and versatile, and have
increased their utility. Concerning the manufacturing of medical devices and pharmacy,
the development of new biomaterials, new manufacturing methods and techniques has
always been the researchers’ focus. Recently, nanotechnology and nanomedicine have
attracted a great deal of attention, which would further enhance the use of biomaterials
in medical devices and pharmacy. In the development of medical devices and
pharmacy, the selection of the proper material to be used is of utmost importance. This
chapter aims to provide a review of the most used biomaterials. After an explanation of
what biomaterials are and what defines them, a more in-depth approach to the major
types of biomaterials is presented, such as metal, polymer, ceramic, and composites;
also, the advantages and disadvantages of biomaterials, their main characteristics, and
preferred applications in the area of medical devices and pharmacy are discussed.

Verzilvering van een collectieve inspanning: context, ontstaan en evolutie van het Tijdschrift voor Sociologie (1980-2004)
Authors: Jacobs An , De Wit Kurt
Published: May 2023

The "Journal of Sociology" (Tijdschrift voor Sociologie), the only scientific sociological journal in Flanders, celebrates its 25th birthday. In these 25 years, the Journal has encountered many difficulties: too little money, too few submitted articles, too much delay in publishing the issues, ... But at the same time, it brought about cooperation between the universities in Flanders, created opportunities for sociologists to meet, and developed a culture in which critical comments by peers became more accepted. In this article, we present the history of the Journal of Sociology. First, we take a look at the predecessors of the Journal, that is, the research and training institutes, the associations, ... that created the climate in which the Journal could develop. Then we describe the creation of the Journal itself: what were the goals and how were they to be reached? Finally, we follow the evolution of the journal, the difficulties it encountered, the Solutions that were sought, the results that were reached.
Klassengebonden stemgedrag en de nieuwe politieke cultuur: stemgedrag en de saillantie van politieke issues in partijprogramma's
Authors: Achterberg Peter
Published: May 2023

This paper investigates the questions how the political culture in twenty western countries has changed in the postwar period and how these changes in political culture are related to the decline in class voting in (most of) these countries, which has been reported by Nieuwbeerta (1995). It appears that old issues, which are related to class-conflict, have declined slightly in the postwar period, while new issues such as ecological and cultural issues have risen in salience remarkably in the same period. Our analysis shows that the most important determinant of the degree of contextual class voting is cultural issue salience. In the end of this paper I discuss the implications of my findings for the 'death of class' debate.
Hoe beleven kinderen in éénoudergezinnen hun gezinscontext?
Authors: Van Peer Christine
Published: May 2023

An increasing number of children is living in a one-parent-family. From the literature it is obvious that educational characteristics in one-parent-families differ from those in traditional families. The research question considered here is whether children perceive these differences as such. If so, these different perceptions potentially give way to differences in well-being. Using data from the CBGS-KRC Children’s Survey (2001, n=1955) the association between the type of family the child lives in and the child’s perception of its educational context is being examined by means of non-parametric tests. The empirical evidence suggests that significant differences exist between the perception of children living with a single parent or in an alternating family context in comparison to children living in traditional families on all the educational traits considered, i.e. the monitoring of the child’s activities by its mother and father, the child’s communication with mother and father, the communication between the parents mutually, the feeling of acceptance by the parents, and the behavioural autonomy the child experiences.
‘Overbrugger of onderscheider?’: hoe frequent ontstaat interetnisch contact via het sportverenigingsleven in Nederland?
Authors: van der Meulen Ruud , Ultee Wout
Published: May 2023

On the one hand, sports clubs are viewed as an ethnic ‘bridger’. On the other hand, they would offer an excellent opportunity to affiliate with people of similar backgrounds. In this article, we develop indices, which we use to describe the number of interethnic ties via sports clubs in the Netherlands at the end of the twentieth-century. We employ both survey and administrative data. Some key findings are: 50 per cent of all sports club members are member of a least one club for a mixed sports branch, 19 per cent of ethnic minority sports club members are member of an ethnic sports club, and 34 per cent of ethnic majority members participate in an ethnically mixed sports group. Taking into account the number of members, the number of members per team, and the composition of its membership base, the vast majority of interethnic ties are forged by soccer clubs.
Senegalese arbeidsmigratie naar Antwerpen: een levensloopanalyse
Authors: Van Nieuwenhuyze Inge
Published: May 2023

This research focuses on an element of migratory experience that has been relatively neglected thus far: a dynamic view of changes over time. The material underpinning the arguments is the qualitative life-course analysis of 35 indepth interviews with Senegalese migrants living in Antwerp. I describe how respondents may move from purely survival stages, over phases of looking for a regularisation of their administrative status, to a more stable context in which they can invest in improving their socio-economic situation. In analysing their life courses, attention is paid to the changing roles of the community, the legal context, and the relationship with home. An in-depth insight is given into the lives of migrants, the limits, rights, and possibilities for getting by in an urban setting. The project shows how a more dynamic approach on the position of newly arrived migrants in receiving economies improves the static perspective common to most theories.
Tussen hoop, angst en verveling: de ervaringen en het welbevinden van asielzoekers in de Belgische asielopvang
Authors: Vandermeerschen Hanne
Published: May 2023

Research has shown that asylum seekers encounter more mental health problems than refugees, who officially have been granted asylum. It is highly probable that the explanation for this has to be sought in the current living conditions of asylum seekers. In this study, we concentrated on the structure and organisation of asylum seekers facilities. Sixteen in-depth interviews with asylum seekers were carried out, in two different settings: an asylum seeker centre and a small-scale facility. We examined how asylum seekers experience their life in the facility they were allocated, and what features have an impact on their well-being (from their point of view). Results show that the prohibition of work and the lack of meaningful activities are perceived as being most problematic. But worries about their future seem to be even more an impediment for well-being.
Onderzoeksnota: tienerzwangerschappen in België in cijfers van 1996 tot 2005.
Authors: De Wilde Marjolijn
Published: May 2023

Teenage pregnancy is an issue of great political and social concern in Belgium. This research note is one of the first to provide for a quantitative analysis of recent figures (1996-2005). Such information is arguably indispensable for drafting effective prevention plans. The highest number of teenage pregnancies (among 10- to 19-year-olds) was recorded in 2001, which was followed by a decrease in numbers, and a slight increase again. In 2005 approximately 5250 girls fell pregnant – a number well below the record of 2001. Among teenagers, abortion rates are growing. Currently, they carry the pregnancy to term in (slightly more than) half of the cases. The majority of teenage pregnancies is found in adolescents 18 years of age or older. The share of younger adolescents shows a slight increase since 1996. In 2004 and 2005 teenage pregnancies made up 4% of the total number of recorded pregnancies. This number stayed well below the percentages of the years before. Although the amount of teenage pregnancies is fairly limited in Belgium, adolescents falling pregnant certainly require the care and attention of policy makers and social workers.
Onderwijs als nieuwe sociale scheidslijn?: de gevolgen van onderwijsexpansie voor sociale mobiliteit, de waarde van diploma's en het relatieve belang van opleiding in Nederland
Authors: Tolsma Jochem , Wolbers Maarten H.J.
Published: May 2023

The increased educational participation has resulted in more social mobility and less social inequality in modern societies. So, educational achievement may have become a new social cleavage in society instead of social origin. Until now, it is unclear whether this actually has been the case, because educational expansion has resulted in credential inflation and probably also to a weakening of the impact of educational qualifications on occupational success. What consequence of educational expansion is dominant in the Netherlands, is unknown. This article focuses on the following questions: What development has occurred in (1) the intergenerational transmission of status positions from parents to their children, (2) the labour market value of credentials in terms of occupational success and (3) education as social cleavage instead of social origin? On the basis of data from the Family Survey Dutch Population 1992-2009, we have shown that the intergenerational transmission of status positions from parents to their offspring has decreased over time, but primarily among men. In addition, credential inflation has taken place in the labour market, which has resulted in a diminished effect of level of education on the occupational status achieved by individuals. Meritocratization in the labour market stagnates. The ultimate consequence is that the relative importance of education, compared to social origin, as a social cleavage has not increased in Dutch society.
Ongelijkheden in het ervaren van conflict in een adolescente siblingdyade: de effecten van geboortevolgorde, geboorteafstand en gendersamenstelling
Authors: Sobczyk Olaf
Published: May 2023

In this article we investigate which structural characteristics of siblings within the dyad cause that some adolescent siblings experience more conflict with each other than others. Regarding the family as a system with a certain status hierar¬ chy, four hypotheses can be formulated about the effects of birth order, spacing and gender constellation. Especially for this study data has been collected of adolescents between 12 and 18 years old from the region of Bruges. Using multilevel analysis, the hypotheses were tested in a sample of 139 dyads. Results indicate that the birth order of the siblings within the dyad and the gender constellation of the dyad determine the amount of perceived conflict in the sibling relation¬ ship. The spacing of siblings does not play a role for sibling conflict in this study. Structural characteristics of siblings and dyads explain thus differences between dyads and between siblings within a dyad.
Agency en structure in de ervaringen van jongeren: een andere kijk op de verklaring van jeugddelinquentie
Authors: Troonbeeckx Sofie , Put Johan , Pleysier Stefaan
Published: May 2023

Numerous explanatory models and theories of youth delinquency focus on one or multiple structural factors, but neglect the importance of the youngster himself and his agency in the process of delinquency. Recent desistance research emphasises agency in the process of quitting crime but fails to provide a clear conceptual framework to study the meaning and explanatory value of agency and structure at the start of the delinquent process. Based on ideas from different disciplines as well as on qualitative interview data with youngsters who reside in juvenile institutions, this article aims to introduce an integrated framework of agency and structure and clarify how these elements can contribute to the explanation of youth delinquency.
De invloed van sociodemografische kenmerken op drop-out van jongeren uit georganiseerde sportactiviteiten
Authors: Bradt Lieve , Van de Walle Tineke , Van der Eecken Annelore , Moerkerke Beatrijs , Loeys Tom
Published: May 2023

Participation in organised sport activities is believed to bring substantial developmental benefits for young people. Consequently, there has been a growing interest in young people’s participation in organised sports, especially concerning socially vulnerable youth. While researchers have thoroughly documented sociodemographic characteristics of ‘non-participants’ and young people’s reasons for dropping out, few studies have focused on relations between youth dropout and socio-demographic factors. In this article, we present findings from a multilevel logistic regression based on data from a school survey conducted by the Youth Research Platform, the Flemish Policy Research Centre Youth, in secondary schools in Antwerp and Ghent. The sample comprises 3.867 young people from the first, second and third grade of secondary education and from diverse sociodemographic backgrounds. All respondents reported on their previous and current sport participation. Our findings reveal that – with the exception of the experience of material wealth – all the variables used in our study had a significant influence on sport dropout. These results indicate that policy that is aimed at stimulating sports participation should not only focus on thresholds to participation but also to exclusion mechanisms within sport clubs.
Intersectionele reflexiviteit: een antwoord op ethische vraagstukken?
Authors: Huysentruyt Heleen
Published: May 2023

How can researchers develop an honest and righteous relation with research participants? The author of this article explores the ethical relevance of ‘intersectional reflexivity’ in research on vulnerable social groups. Intersectional reflexivity questions the objectivity of social reality and encourages researchers to pay attention to the different ways in which their own social positioning influences their research. Drawing on her own ethnographic research on homophobic violence in Brussels, the author proposes a number of tools that might foster the methodological application of ‘thick intersectionality’ in social science research. Such an application implies, among other things, that researchers pay more attention to multiple and changing forms of inequality that might characterize and influence the relationship between researcher and participants throughout different phases of the research project. The implementation of ‘thick intersectionality’ would consequently allow scholars to generate more reliable research results and to expose power relations that are inherent to the research process.
Veilige hechting met ouders, leerkrachten en school, sociale cohesie op school en etnische vooroordelen bij Vlaamse jongeren
Authors: Vervaet Roselien , Van Houtte Mieke , Stevens Peter A.J.
Published: May 2023

As a result of global migration processes, schools in Flanders are now notably ethnically diverse. Taking into consideration the lack of research on determinants of Flemish students’ ethnic prejudice and Bowlby’s attachment theory, we want to examine the role of the individual feeling of attachment and the social cohesion in schools for Flemish students’ degree of ethnic prejudice in secondary education. Moreover, we control for ethnic school composition and pupil characteristics that have been shown to be related to ethnic prejudice. The data used are taken from the Racism and Discrimination in Secondary Schools Research (RaDiSS 2), collected by means of a written questionnaire by 2.058 students and 669 teachers in 40 Flemish secondary schools. The main finding of this study is that the individual feeling of being securely attached is associated with lower levels of ethnic prejudice: Flemish pupils who feel supported by their parents, teachers and school are less ethnic prejudiced. Moreover, social cohesion in a school is related with lower degrees of ethnic prejudice among Flemish students.
Is sport een facilitator voor integratie?: een kwalitatieve analyse van interetnische vriendschappen en sociaal kapitaal in sportclubs
Authors: Wauters Joris , Levrau François , Michielsen Joris , Clycq Noel , Timmermans Christiane
Published: May 2023

Sports clubs are often seen as catalysts for integration. This paper analyses what social mechanisms and dynamics within a sports club can contribute to the development of interethnic relations. We define four theoretical scenarios wherein these interethnic relations do or do not develop. The scenarios are defined by the high or low symbolic cost to be paid in the sports club context when engaging in an interethnic relationship; and by how highly someone’s sport skills are valued in the Bourdieuan ‘field’ of a sports club. Based on eighteen individual semi-structured interviews with youngsters in a soccer and basketball club, we illustrate how interethnic relations develop in both clubs. Using the concepts of bonding and bridging social capital, we analyse the added value respondents can get out of these relationships. Although we define the links between them as ‘weak ties’, added value is created by the exchange of information (c.q. language, the city, school, religion); and, additionally, we find how these relationships create a more open mind vis-à-vis social diversity.
Verantwoordelijke keuzes in het licht van genetische kennis: een sociologische studie naar het leven met een genetische aanleg bij Belgische BRCA-mutatiedragers
Authors: Wauters Annet , Van Hoyweghen Ine
Published: May 2023

In line with studies in sociology of genetics on the social implications of genetic information, this article focuses on the choices and responsibilities that arise when genetics, more specifically the presence of a BRCA mutation in the family, enters individuals’ daily lives. In order to study the lived experiences with genetics, we conducted 28 semi-structured in-depth interviews with Belgian BRCA mutation carriers. Based on Lemke’s (2013) dimensions of ‘genetic responsibility’ – that is, ‘responsibility for the self’, ‘informational responsibility’ and ‘reproductive responsibility’ – the article examines how people with a BRCA mutation handle making ‘responsible choices’ and how they learn to cope with this in their lives. The results of the study show that respondents wrestle with the various options, dilemmas and limitations involved in the responsibilities tied up with genetic knowledge. Not only is taking responsibility for every sole dimension a burden, but the combination of responsibilities, or more precisely the lack of a feasible combination, appears to be a complex task. In addition, this worrying about genetics apparently is an unceasing chore. Sometimes, individuals manage to accommodate genetics in their lives, but at other times they are unavoidably confronted with it again and forced to make new choices. Respondents consider genetics as a constant theme impinging on their lives. The social dimensions of dealing with genetics give rise to many concerns and they require a serious amount of human effort to socially absorb that knowledge and to accommodate it.
Kwartiermaken als symbolische politiek in overheidsgestuurde gentrificatie
Authors: Hoekstra Myrte , Van Gent Wouter , Boterman Willem
Published: May 2023

This paper discusses state interventions concerning the urban renewal of a poor working-class neighbourhood in North Amsterdam - Van der Pekbuurt. These interventions are often studied from a perspective of state-sponsored gentrification, in which the (local) state functions as driver for urban transformation. Here, policies are not limited to restructuring the housing market and the physical and social renewal of ‘problem neighbourhoods’ but also include cultural policies, in particular the creation of cultural amenities for the creative urban middle-class. Our analysis shows that these policies contribute to a discourse of ‘natural’ development of Van der Pekbuurt from a working-class neighbourhood to a gentrification neighbourhood, while the local government invests in the development of a middle-class, culturalcreative aesthetic that closely matches the wishes of local developers. Due to the dominance of this symbolic frame, the perspectives of non-middle-class residents are ignored and the legitimacy of their presence in the neighbourhood is undermined. In contrast to the creative middle-class, however, these residents experience a lack of support for their position.

Development of Metaphor Reasoning Comprehension in Infants
Authors: Lee Eun Kyoung , Choi Seong Hee
Published: May 2023

Purpose: This study investigated the development of early metaphor comprehension based on gender and age in preschool children and measured its correlation with vocabulary acquisition.Methods: A total of forty-nine Korean preschoolers aged 4 to 6 years old (17 boys, 32 girls) with normal receptive and expressive vocabulary development were included in this study. Children were divided into three groups depending on age, their mean ages being 4;8, 5;4, 6;3, respectively. Metaphor reasoning comprehension was measured using MRAC(Metaphor and Reasoning Comprehension Test), and children were asked to listen to a sentence and point to one of the three pictures.Results: There was no significant difference among the groups in the metaphor reasoning score by age and gender of preschool children (p>0.05). In addition, the Pearson correlation showed a positive relationship between metaphor and reasoning comprehension scores, as well as receptive vocabulary scores (r=0.302, p=0.035) and a positive relationship between metaphor and reasoning comprehension scores and expressive vocabulary scores (r=0.314, p=0.028). In addition, most errors occur in understanding the literal meaning rather than the implied meaning or metaphor of the sentence.Conclusion: In early young children, vocabulary plays an essential role in the metaphor interpretation process. However, to better understand the development of metaphor language comprehension in preschool children, exploring other factors affecting their ability to understand metaphor language and investigating their relationships is necessary.
