The family alliance assessment scales : steps toward validity and reliability of an observational assessment tool for early family interactions

We present the first steps in the validation of an observational tool for father-mother-infant interactions: the FAAS (Family Alliance Assessment Scales). Family-level variables are acknowledged as unique contributors to the understanding of the socio-affective development of the child, yet producing reliable assessments of family-level interactions poses a methodological challenge. There is, therefore, a clear need for a validated and clinically relevant tool. This validation study has been carried out on three samples: one non-referred sample, of families taking part in a study on the transition to parenthood (normative sample; n = 30), one referred for medically assisted procreation (infertility sample; n = 30) and one referred for a psychiatric condition in one parent (clinical sample; n = 15). Results show that the FAAS scales have (1) good inter-rater reliability and (2) good validity, as assessed through known-group validity by comparing the three samples and through concurrent validity by checking family interactions against parents' self-reported marital satisfaction.

Melanin-based colorations signal strategies to cope with poor and rich environments

One hypothesis for the maintenance of genetic variation states that alternative genotypes are adapted to different environmental conditions (i.e., genotype-by-environment interaction GxE) that vary in space and time. Although GxE has been demonstrated for morphological traits, little evidence has been given whether these GxE are associated with traits used as signal in mate choice. In three wild bird species, we investigated whether the degree of melanin-based coloration, a heritable trait, covaries with nestling growth rate in rich and poor environments. Variation in the degree of reddish-brown phaeomelanism is pronounced in the barn owl (Tyto alba) and tawny owl (Strix aluco), and variation in black eumelanism in the barn owl and Alpine swift (Apus melba). Melanin-based coloration has been shown to be a criterion in mate choice in the barn owl. We cross-fostered hatchlings to test whether nestlings sired by parents displaying melanin-based colorations to different extent exhibit alternative growth trajectories when raised by foster parents in poor (experimentally enlarged broods) and rich (experimentally reduced broods) environments. With respect to phaeomelanism, barn owl and tawny owl offspring sired by redder parents grew more rapidly in body mass only in experimentally reduced broods. With respect to eumelanism, Alpine swift offspring of darker fathers grew their wings more rapidly only in experimentally enlarged broods, a difference that was not detected in reduced broods. These interactions between parental melanism and offspring growth rate indicate that individuals display substantial plasticity in response to the rearing environment which is associated with the degree of melanism: at least with respect to nestling growth, phaeomelanic and eumelanic individuals are best adapted to rich and poor environments, respectively. It now remains to be investigated why eumelanism and phaeomelanism have a different signaling function and what the lifelong consequences of these melanism-dependent allocation strategies are. This is important to fully appraise the role played by environmental heterogeneity in maintaining variation in the degree of melanin-based coloration.

Wishes or Constraints? Mothers' Labour Force Participation and its Motivation in Switzerland

The aim of this article is to estimate the impact of various factors related to role conflict theory and preference theory on the reduction of women's labour force participation after their transition to parenthood. Objective and subjective dimensions of women's labour force participation are assessed. The empirical test is based on a survey of couples with children in Switzerland. Results show that compared to structural factors associated with role conflict reduction, preferences have little impact on mothers' labour force participation, but explain a good deal of their frustration if the factual situation does not correspond to their wishes. Structural factors, such as occupation, economic resources, childcare, and an urban environment, support mothers' labour force participation, whereas active networks and a home centred lifestyle preference help them to cope with frustrations.

Phylogéographie des principales vipères européennes (Vipera ammodytes, V. aspis et V. berus), structuration génétique et multipaternité chez Vipera berus

Résumé: Les vipères du genre Vipera sont des serpents venimeux distribués dans la totalité du Paléarctique. Malgré cette répartition considérable, elles sont extrêmement menacées, leur déclin étant principalement dû à la destruction et à la fragmentation de leur habitat ainsi qu'à la persécution humaine. Afin d'apporter de nouveaux éléments dans le contexte de la protection de ce groupe de reptiles, nous avons utilisé durant ce travail de thèse différents marqueurs moléculaires pour étudier la structuration génétique à petite et à large échelle chez trois espèces appartenant au genre Vipera. La première étude, une phylogéographie moléculaire de la vipère ammodytes (Vipera ammodytes), a montré dans l'ensemble de l'aire de répartition une forte structuration génétique provenant d'isolements antérieures au Pléistocène. La présence d'un nombre important de clades dans le centre des Balkans suggère que cette région a fourni de nombreux refuges isolés durant les glaciations. Ces dernières ont également eu un impact considérable sur la diversité génétique au sein de la majorité des clades, suite à d'importants goulots d'étranglement durant le Pléistocène. L'étude de la phylogéographie de la vipère aspic (Vipera aspis) a montré une différenciation génétique entre les populations présentes de chaque côté des Alpes, mais également une forte structuration interne avec la mise en évidence d'un refuge en France. Cette étude est la première à établir clairement l'utilisation d'un refuge français pour un vertébré terrestre. La troisième partie de cette thèse a étudié la phylogéographie de la vipère péliade (Vipera berus), espèce cible de ce travail. En plus de la mise en évidence d'un groupe génétique inattendu (localisé dans le nord de l'Italie, le sud de l'Autriche, le nord de la Slovénie et l'extrême sud-est de la Suisse), la variabilité génétique au sein du groupe nordique (comprenant les animaux de l'entier de l'aire de répartition de l'espèce à l'exception des individus du groupe italien et les animaux provenant des Balkans) est suffisamment importante pour conclure à l'utilisation de refuges glaciaires nordiques durant les dernières glaciations, en complément des refuges habituellement décrits pour la majorité des espèces animales (soit les péninsules ibérique, italienne et balakanique). Ces résultats nous ont conduit à effectuer une étude morphologique (quatrième partie) comparant les vipères péliades du "clade italien" et du "clade nordique" décrits ci-dessus. Seules de petites différences morphologiques ont pu être mises en évidence, malgré une séparation de ces groupes estimée à plus d'un million d'années. Une étude à plus petite échelle, centrée sur le Massif jurassien et certaines populations alpines et françaises, a été entreprise afin d'estimer leur diversité génétique et d'évaluer la structuration génétique entre les populations à l'aide de marqueurs microsatellites (cinquième partie). Une importante structuration a été observée entre les populations distantes de plus de 3 kilomètres, la structuration entre les populations plus proches étant plus limitée. De plus, une diversité génétique plus faible dans les populations jurassiennes et alpines comparativement aux populations du massif central et de la côte atlantique a été constatée, probablement due à une perte de diversité génétique lors de la recolonisation post-glaciaire. La sixième étude s'est intéressée au succès reproducteur des mâles de vipères péliades en conditions naturelles. Une corrélation entre la taille des mâles et leur succès reproducteur a été relevée, les individus de plus grande taille ayant un succès reproducteur plus élevé. Le taux de multipaternité a aussi été investigué, démontrant que la proportion de pontes issues de plusieurs pères est élevée (69%) malgré la faible densité de vipères observée sur le site étudié. Finalement, aucun lien entre le nombre de pères au sein d'une ponte et la mortalité des jeunes à la naissance n'a pu être mis en évidence, contrastant avec des travaux précédents. En conclusion, l'observation de la structuration très marquée chez les vipères péliades devrait permettre d'affiner les méthodes de protection de l'espèce dans le massif jurassien. A plus large échelle, l'importante structuration génétique observée chez les vipères ammodytes, aspic et péliade résultant de l'utilisation de nombreux refuges glaciaires, complémentaires aux refuges habituellement utilisés par les espèces animales, démontre l'intérêt de l'analyse phylogéographique des reptiles pour la compréhension des phénomènes de colonisation et d' extinction des populations durant la fin du Tertiaire et le Quaternaire. La mise en évidence chez les différentes espèces de vipères étudiées de nombreux groupes génétiques distincts (ESUs) devrait conduire à des modifications de la taxonomie ainsi qu'au statut de protection de ces espèces. Abstract: The vipers of the genus Vipera are venomous snakes widespread throughout the Palaearctic regions. Despite a large distribution area, several species are extremely threatened, especially due to the destruction and fragmentation of their habitats, as well as by human persecution. In order to increase the knowledge on these species and to improve their protection, several molecular markers have been used to investigate the genetic structure on small and large scales, within three species of the genus Vipera. The first study, a molecular phylogeography of the nose-horned viper (Vipera ammodytes), showed a considerable structuring throughout the distribution area, due to isolation into refugia before the Pleistocene. A high number of clades in the centre of the Balkans suggests that this region harboured numerous isolated glacial refugia during the last glaciation. Moreover, low genetic diversity within several clades implies that most populations of nose-horned vipers have suffered bottlenecks during the Pleistocene. The study of the phylogeography of the asp viper (Vipera aspis) showed genetic differentiation between populations on each side of the Alps, as well as considerable internal genetic structure, suggesting the use of a glacial refugium in France. This study is the first to establish firmly the occurrence of a French refugia for a terrestrial vertebrate. The third part of this work involved a phylogeographic study of the adder (Vipera berus), the target species of this thesis. Three clades were revealed: a Balkan clade (corresponding to the subspecies V. b. sachalinensis), an unexpected Italian clade (limited to northern Italy, southern Austria, northern Slovenia and southeasternmost corner of Switzerland) and a Northern clade clade (including adders of the whole distribution area excepted animals from the Balkan and the Italian clades). The genetic variability within the Northern clade is sufficiently high to conclude that a northern glacial refugia during the last glaciation, in addition to those refugia already described for the main species (Iberian, Italian and Balkan peninsula). These results motivated a morphological study (part four) comparing the adders from the Italian and the Northern clades describe above. Only small morphological differences have been found, despite the split between these two clades have taken place more than 1 million years ago. A study on a local scale, focused on the Jura Mountains, on a few populations in the Alps and France was, performed to estimate the genetic diversity and the genetic structure between populations using microsatellite markers (part five). Considerable structure was observed between populations separated by more than 3 kilometres, whereas the structure between closer populations is less marked. Moreover, lower genetic diversity in the populations from Jura Mountains and Alps was noticed compared to populations from Massif Central of Atlantic coast. Such loss of genetic variation probably followed post-glacial recolonisation. The sixth study focused on the reproductive success of male adders in the wild. A positive correlation between body length and reproductive success was observed. Multiple paternity was also observed in most of clutches (69%) despite the low density of adders in the study area. Finally, no relationship was found between the number of fathers in a clutch and the survival of offspring at birth, contradicting previous studies. To conclude, the observation of a significant genetic structure in Vipera berus will enable recommendations to be made to improve protection of this species in the Jura Mountain. On a larger scale, the considerable genetic structure found within Vipera ammdoytes, V. aspis and V. berus, resulting from isolation in additional glacial refugia to those already described for other species, demonstrates the relevance of phylogeographic studies of reptiles to better understand the colonisation and disappearance during the last Tertiary and the Quaternary. The observation of several groups of evolutionary significant units (ESUs) within the three studied species might lead to a revision of the taxonomy, as well as their conservation status.

Is blood still thicker than water? A life-course perspective on the transformation of family and friends' roles in personal networks

This thesis addresses the issue of the moving boundaries between family and friends' roles in personal networks, adopting a life-course perspective and using Switzerland as a case study. In a period of major changes in personal life happening in contemporary Western societies, understanding the organization of personal networks intertwined with the unfolding of individual life courses is of prime importance in facing new challenges with regard to social integration. The data stem from a representative national survey carried out in 2011 named Family tiMes, including 803 individuals born either in 1950-1955 or in 1970-1975. An innovative research design was adopted, combing cross-sectional ego-centered network data and retrospective longitudinal life-course data. The results show continuing boundaries between family and friends' roles and that family keeps a prominent role in personal networks despite the notable importance of friendship ties. One relationship stands out above all, that with the partner, followed quite a few steps behind by those with children. Regarding life courses, de-standardization tendencies were found in family formation and also a persistent gendering of occupational trajectories. Two kinds of life trajectories are particularly intertwined with personal networks, co-residence and partnership trajectories, both related to the unfolding of family life. In particular, transition to parenthood functions as a turning point in individuals' lives, deeply transforming their sociability. Finally, a twofold pluralization process was identified, affecting simultaneously the organization of personal networks and the unfolding of individual life courses. This thesis contributes to the literature on the sociology of family and personal life, and to fruitful interlinkage between the network approach and the life-course perspective.

Performance of parental history for the targeted screening of hypertension in children.

OBJECTIVES: Several guidelines recommend universal screening for hypertension in childhood and adolescence. Targeted screening to children with parental history of hypertension could be a more efficient strategy than universal screening. Therefore, we assessed the association between parental history of hypertension and hypertension in children, and estimated the sensitivity, specificity, negative, and positive predictive values of parental history of hypertension for hypertension in children. METHODS: The present study was a school-based cross-sectional study including 5207 children aged 10-14 years from all public 6th grade classes in the Canton of Vaud, Switzerland. Children had hypertension if they had sustained elevated blood pressure over three separate visits. RESULTS: In children, the prevalence of hypertension was 2.2%. Some 8.5% of mothers and 12.9% of fathers reported to be hypertensive. Maternal history of hypertension (odds ratio 2.0, 95% confidence interval 1.2-3.3) and paternal history of hypertension (odds ratio 2.2, 95% confidence interval 1.4-3.6) were independent risk factors for hypertension in children. Nevertheless, the sensitivity of parental history of hypertension for the identification of hypertension in children was low (from 4% for both parents' positive history up to 41% for at least one parent's positive history). Positive predictive values were also low (between 4 and 5%). CONCLUSION: Children with hypertensive parents were at higher risk of hypertension. Nevertheless, parental history of hypertension helped only marginally to identify hypertension in offspring. Targeting screening only toward children with a parental history of hypertension may not be a substantially better strategy to identify hypertension in children compared with universal screening.

Signalling value of maternal and paternal melanism in the barn owl : implication for the resolution of the lek paradox

Secondary sexual characters often signal qualities such as physiological processes associated with resistance to various sources of stress. When the expression of an ornament is not sex-limited, we can identify the costs and benefits of displaying a trait that is typical of its own sex or of the other sex. Indeed, the magnitude and sign of the covariation between physiology and the extent to which an ornament is expressed could differ between males and females if, for instance, the regulation of physiological processes is sensitive to sex hormones. Using data collected over 14 years in the nocturnal barn owl Tyto alba, we investigated how nestling body mass covaries with a heritable melanin-based sex-trait, females displaying on average larger black feather spots than males. Independently of nestling sex, year and time of the day large-spotted nestlings were heavier than small-spotted nestlings. In contrast, the magnitude and sign of the covariation between nestling body mass and the size of parental spots varied along the day in a way that depended on the year and parental gender. In poor years, offspring of smaller-spotted mothers were heavier throughout the resting period; in the morning, offspring sired by larger-spotted fathers were heavier than offspring of smaller-spotted fathers, while in the evening the opposite pattern was found. Thus, maternal and paternal coloration is differentially associated with behaviour or physiology, processes that are sensitive to time of the day and environmental factors. Interestingly, the covariation between offspring body mass and paternal coloration is more sensitive to these environmental factors than the covariation with maternal coloration. This indicates that the benefit of pairing with differently spotted males may depend on environmental conditions, which could help maintain genetic variation in the face of intense directional (sexual) selection.

An 8-Item Short Form of the Inventory of Dimensions of Emerging Adulthood (IDEA) Among Young Swiss Men.

Emerging adulthood is a period of life transition, in which youths are no longer adolescents but have not yet reached full adulthood. Measuring emerging adulthood is crucial because of its association with psychopathology and risky behaviors such as substance use. Unfortunately, the only validated scale for such measurement has a long format (Inventory of Dimensions of Emerging Adulthood [IDEA]-31 items). This study aimed to test whether a shorter form yields satisfactory results without substantial loss of information among a sample of young Swiss men. Data from the longitudinal Cohort Study on Substance Use Risk Factors were used (N = 5,049). IDEA, adulthood markers (e.g., parenthood or financial independence), and risk factors (i.e., substance use and mental health issues) were assessed. The results showed that an 8-item, short-form scale (IDEA-8) with four factors (experimentation, negativity, identity exploration, and feeling in between) returned satisfactory results, including good psychometric properties, high convergence with the initial scale, and strong empirical validity. This study was a step toward downsizing a measure of emerging adulthood. Indeed, this 8-item short form is a good alternative to the 31-item long form and could be more convenient for surveys with constraints on questionnaire length. Moreover, it should help health care practitioners in identifying at-risk populations to prevent and treat risky behaviors.

Morph-specific genetic and environmental variation in innate and acquired immune response in a color polymorphic raptor.

Genetic color polymorphism is widespread in nature. There is an increasing interest in understanding the adaptive value of heritable color variation and trade-off resolution by differently colored individuals. Melanin-based pigmentation is often associated with variation in many different life history traits. These associations have recently been suggested to be the outcome of pleiotropic effects of the melanocortin system. Although pharmacological research supports that MC1R, a gene with a major role in vertebrate pigmentation, has important immunomodulatory effects, evidence regarding pleiotropy at MC1R in natural populations is still under debate. We experimentally assessed whether MC1R-based pigmentation covaries with both inflammatory and humoral immune responses in the color polymorphic Eleonora's falcon. By means of a cross-fostering experiment, we disentangled potential genetic effects from environmental effects on the covariation between coloration and immunity. Variation in both immune responses was primarily due to genetic factors via the nestlings' MC1R-related color genotype/phenotype, although environmental effects via the color morph of the foster father also had an influence. Overall, dark nestlings had lower immune responses than pale ones. The effect of the color morph of the foster father was also high, but in the opposite direction, and nestlings raised by dark eumelanic foster fathers had higher immune responses than those raised by pale foster fathers. Although we cannot completely discard alternative explanations, our results suggest that MC1R might influence immunity in this species. Morph-specific variation in immunity as well as pathogen pressure may therefore contribute to the long-term maintenance of genetic color polymorphism in natural populations.

What young people with spina bifida want to know about sex and are not being told.

OBJECTIVE: The aim of this paper was to examine sexual knowledge, concerns and needs of youth with spina bifida (SB) to inform the medical community on ways to better support their sexual health. METHODS: As part of the Video Intervention/Prevention Assessment (VIA) - transitions, a prospective cohort study, 309 h of video data were collected from 14 participants (13-28 years old) with SB. Participants were loaned a video camcorder for 8-12 weeks to shoot visual narratives about any aspects of their lives. V/A visual narratives were analysed with grounded theory using NVivo. RESULTS: Out of 14 participants, 11 (six women) addressed issues surrounding romantic relationships and sexuality in their video clips. Analysis revealed shared concerns, questions and challenges regarding sexuality gathered under four main themes: romantic relationships, sexuality, fertility and parenthood, and need for more talk on sexuality. CONCLUSIONS: Youth with SB reported difficulties in finding answers to questions regarding their sexuality, romantic relationships and fertility. This study revealed a need for help from the medical community to inform and empower youth with SB in the area of sexual health. Through sexual and reproductive health education with patients and parents starting at an early age, medical providers can further encourage healthy emotional and physical development in adolescents transitioning into adulthood.

The present article examines the final part of the regnal formulas in the Book of Kings, i.e. the epilogue formulary. Most reports of the kings of Israel and Judah end with an epilogue containing formulaic statements about the death of the king and his succession. Typically, the epilogue formula is introduced by the phrase (source reference): 'Now the rest of the acts of PN1, are they not written in the Book of the Chronicles of the Kings of Judah (of the Chronicles of the Kings of Israel)?' and consists of three elements: 1. Dynastic notice ('PN1 slept with his fathers'); 2. Statement of burial; 3. Statement of succession. Sometimes one, two or all three of these elements are altered or lacking. The epilogue formulae of the Judean kings are more consistent than those of the Israelite kings; the latter often lacks a burial notice. Interestingly, the accounts of the deported (arrested) kings (Hoshea: 2 Kgs 17:6, Jehoahaz: 23:34, Zedekiah:25:7 and Jehoiachin: 25:27-30) do not contain an epilogue at all, nor the accounts of the reigns of Ahaziah and Athaliah which mark an episode of disruption in the history of the Davidic kingdom. For all these kings even the phrase 'Now the rest of the acts of PN1, are they not written in the Book of the Chronicles of... ?' is lacking. The absence of an epilogue in these cases is probably due to the fact that the king's succession (cf. element 3) is considered a constitutive and indispensable component of the epilogue. In the first instance, the approach of this study is descriptive and philological; it aims to contribute to the understanding of the notices. Secondly, the study addresses the question how the irregularities and variations within the formulae are to be explained. In particular, the study will pay attention to differences between the epilogue formulae concerning the kings of Israel and those concerning the Judean kings. At the end, questions concerning the epilogues formula's provenance and its formation date and concerning further redactional developments will be considered.

Quality of Life in Swiss Paediatric Inflammatory Bowel Disease Patients: Do Patients and Their Parents Experience Disease in the Same Way?

BACKGROUND AND AIMS: Inflammatory bowel diseases (IBDs) may impair quality of life (QoL) in paediatric patients. We aimed to evaluate in a nationwide cohort whether patients experience QoL in a different way when compared with their parents. METHODS: Sociodemographic and psychosocial characteristics were prospectively acquired from paediatric patients and their parents included in the Swiss IBD Cohort Study. Disease activity was evaluated by the Paediatric Crohn's Disease Activity Index (PCDAI) and the Paediatric Ulcerative Colitis Activity Index (PUCAI). We assessed QoL using the KIDSCREEN questionnaire. The QoL domains were analysed and compared between children and parents according to type of disease, parents' age, origin, education and marital status. RESULTS: We included 110 children and parents (59 Crohn's disease [CD], 45 ulcerative colitis [UC], 6 IBD unclassified [IBDU]). There was no significant difference in QoL between CD and UC/IBDU, whether the disease was active or in remission. Parents perceived overall QoL, as well as 'mood', 'family' and 'friends' domains, lower than the children themselves, independently of their place of birth and education. However, better concordance was found on 'school performance' and 'physical activity' domains. Marital status and age of parents significantly influenced the evaluation of QoL. Mothers and fathers being married or cohabiting perceived significantly lower mood, family and friends domains than their children, whereas mothers living alone had a lower perception of the friends domain; fathers living alone had a lower perception of family and mood subscores. CONCLUSION: Parents of Swiss paediatric IBD patients significantly underestimate overall QoL and domains of QoL of their children independently of origin and education.

Double brooding and offspring desertion in the barn owl (Tyto alba)

Many bird species produce two annual broods during a single breeding season. However, not all individuals reproduce twice in the same year suggesting that double brooding is condition-dependent. In contrast to most raptors and owls, the barn owl Tyto alba produces two annual clutches in most worldwide distributed populations. Nevertheless, the determinants of double brooding are still poorly studied. We performed such a study in a Swiss barn owl population monitored between 1990 and 2014. The annual frequency of double brooding varied from 0 to 14% for males and 0 to 59% for females. The likelihood of double brooding was higher when individuals initiated their first clutch early rather than late in the season and when males had few rather than many offspring at the first nest. Despite the reproductive benefits of double brooding (single- and double-brooded individuals produced 3.97 +/- 0.11 and 7.07 +/- 0.24 fledglings, respectively), double brooding appears to be traded off against offspring quality because at the first nest double-brooded males produced poorer quality offspring than single-brooded males. This might explain why females desert their first mate to produce a second brood with another male without jeopardizing reproductive success at the first nest. Furthermore, the reproductive cycle being very long in the barn owl (120 d from start of laying to offspring independence), selection may have favoured behaviours that accelerate the initiation of a second annual brood. Accordingly, half of the double-brooded females abandoned their young offspring to look for a new partner in order to initiate the second breeding attempt, 9.48 d earlier than when producing the second brood with the same partner. We conclude that male and female barn owls adopt different reproductive strategies. Females have more opportunities to reproduce twice in a single season than males because mothers are not strictly required during the entire rearing period in contrast to fathers. A high proportion of male floaters may also encourage females to desert their first brood to re-nest with a new male who is free of parental care duties.
