Kompatibilita názorů na rodičovství v párech / Compatibility of opinions on parenting in couplesHurychová, Alice January 2016 (has links)
The aim of this study is to compare views on parenting of partners (from a gender perspective) in families caring for children. Changes in women's position in society, their increasing financial contribution to the family budget and therefore economic background influence the opinions about the overall organization of family life, which is reflected in the actual division of parental roles and associated responsibilities. Although the paper focuses primarily on the opinions and ideas about parenting, I did not fail to devote some space also their subsequent practice. Close interaction of people who share a household and raising children, can result in blindness, which in turn creates the feeling of certain conformity of opinion. Parents can sometimes mistakenly believe that their views on parenthood are shared by their partners. In the research I have included ten couples raising two or more children. For the chosen method of semi-structured interviews, I selected respondents from my circle of acquaintances. The choice was quite deliberate, as with many of them I knew for a long time. Therefore I have had an opportunity to watch some of their educational practices or behaviors, and wondered whether their views correspond to their actions. An important aspect when examining the similarities or...

[en] TRANSITION TO PARENTHOOD DURING COVID-19 PANDEMIC: PATERNAL EXPERIENCES AND REPERCUSSIONS TO THE CONJUGALITY / [pt] TRANSIÇÃO PARA A PATERNIDADE DURANTE A PANDEMIA DA COVID-19: EXPERIÊNCIAS PATERNAS E REPERCUSSÕES NA CONJUGALIDADEALESSANDRA FURTADO T H LASSEN 07 April 2022 (has links)
[pt] Este trabalho tem como objetivo geral investigar a experiência de pais de
crianças pequenas, ao longo do período de isolamento social imposto para
contenção da pandemia da COVID-19, e suas repercussões na conjugalidade.
Considerando que o período de transição para a parentalidade é definido pela
literatura de família e casal como especialmente carregado de desafios para a
família nuclear e ampliada, e que os estudos sobre a ótica paterna se encontram em
menor número quando comparados aos estudos sobre a díade mãe-bebê, foram
entrevistados 10 pais primíparos, das cidades do Rio de Janeiro e de São Paulo,
brancos, heterossexuais, pertencentes às camadas médias da população. As
entrevistas foram gravadas, transcritas e submetidas ao método de análise de
conteúdo, na modalidade categorial temática. As análises foram realizadas sob a
perspectiva sistêmica de família e casal articulada a conceitos psicanalíticos. Os
resultados mostraram que o isolamento social decorrente da pandemia foi percebido
como positivo para o exercício da paternidade de pais de crianças pequenas, uma
vez que aumentou o tempo de disponibilidade de interação pai-filho. Já em relação
ao casal conjugal, os resultados mostraram que o isolamento social decorrente da
pandemia foi percebido como um fator de estresse sobreposto aos desafios já
inerentes ao período. / [en] This paper s general objective is to investigate the experiences of fathers of
small children during the isolation period imposed by the Covid-19 pandemic and
the repercussion of this period in conjugality. Considering the couples and family
literature defines the transition period to parenthood as a particularly defying one
to both nuclear and expanded families, and that studies focusing on the fathers
experience are vastly outnumbered by those studying the mother child relationship,
10 subjects of first born children from Rio de Janeiro who are white, heterosexual
and middle class, were interviewed for this paper. The interviews were recorded,
transcribed and submitted to the thematic categorial content analysis method. The
analysis were conducted within the systemic family and couple perspective
articulated with psychoanalytical concepts. The results showed that the social
isolation imposed by the pandemic was perceived as being positive for fatherhood,
as subjects had more time available to interact with their children. In regards to the
couples relationship, the results show that the isolation imposed by the pandemic
was perceived as being an added stress factor to the already difficult period for the
subjects.

Socialinė rizika: samprata ir ryšys su socialinės apsaugos išmokomis / Social risk: conception and relation with social security benefitsDubovskaja, Ivona 25 June 2014 (has links)
Socialinės apsaugos sistema susiformavo XX a., kai esant ekonominiam socialiniam pakilimui, vis labiau tapo svarbu apsaugoti darbuotoją nuo keliamų socialinių rizikų pasekmių. Socialinę apsaugą galima apibudinti kaip ne tik valstybės priemone taikoma socialinės rizikos atveju, bet ir kaip garantas, įstatyme numatytų atveju šeimai nelikti be pragyvenimo lėšų. Socialinė apsauga yra stipriai įtakojama ekonominiais rodikliais, todėl sulėtėjus ekonomikai, padidėjus socialinės apsaugos išlaidoms, valstybės turi reformuoti socialinės apsaugos sistemą. Esant tokiems ekonominiams pokyčiams, socialinės apsaugos sistema tampa nuolat kintanti ir nestabili, nors nepraranda savo esmės ir siekia savo tikslų. Socialinės rizikos kaip socialinis institutas, su apibrėžtomis ribomis, skirtas socialinės apsaugos sistemai įgyvendinti. Socialinė rizika – tai tikėtini įvykiai, nuo kurių padarinių yra numatytos socialinės apsaugos priemonės. Išskiriamos tokios tradicinės socialines rizikos: senatvė (asmuo dėl amžiaus negali užsidirbti pakankamai lėšų), neįgalumas (dalinis arba visiškas darbingo amžiaus asmens negalėjimas dirbti), nelaimingi atsitikimai darbe ar profesinė liga (ūmus darbuotojo sveikatos sutrikdymas dėl trumpalaikio pavojingo, kenksmingo darbo aplinkos poveikio arba neatsargumo, dėl kurio darbuotojas netenka darbingumo), nedarbas (asmuo ne savo noru neturi mokamo darbo ir, būdamas darbingas, negali jo rasti), motinystė (medicininė priežiūra nėštumo ir motinystės metu), sveikata... [toliau žr. visą tekstą] / Social Security System was formed in the twentieth century, when a social economic upturn, has become increasingly important to protect workers from risks posed by the social consequences. Social protection can be characterized as not only the state measure of social risk, but also as a guarantor, the law provided for the family to remove the case without means of subsistence. Social security is strongly influenced by economic indicators, the slowdown of the economy, increasing social security costs, countries have to reform the social security system. With these economic changes, social security system is constantly changing and unstable, although not lose its essence and achieve its goals. Social risks as a social institute, with defined boundaries, is intended for realized social security system. Social risk - the likelihood of events, from which results are provided for social security measures. Such a distinction is made between traditional social risks: old age (the age a person can not earn enough money), invalidity (partial or total working-age person inability to work), employment injuries and occupational diseases (acute worker health-threatening disruption of short-term, harmful effects of the working environment or negligence, for which the employee ceases to work), unemployment (as a working person does not have gainful employment and can not find it), maternity benefits (medical care during pregnancy and motherhood), health (patients treatment, rehabilitation...

Inbreeding and its avoidance in a wild bird populationSzulkin, Marta January 2007 (has links)
Inbreeding occurs when relatives mate and have offspring. Inbreeding depression is hypothesized to have influenced the evolution of mating systems and behavioural mechanisms of inbreeding avoidance in the animal kingdom. Inbreeding in the wild is difficult to measure, as in order to build a pedigree allowing us to identify matings between relatives, the identity of as many as possible members of a population needs to be known. For a long time, the main source of knowledge about inbreeding depression was based on laboratory and agricultural studies, which did not reflect the array of environmental pressures wild populations have to cope with. In consequence, the deleterious consequences of inbreeding have often been underestimated. This is problematic because accurate estimates of the effect size of inbreeding depression are needed to study the strength of selection on inbreeding avoidance mechanisms, and are also of importance to conservation genetics. The aim of this thesis was to use pedigree data to infer the occurrence and effects of inbreeding using over forty years of breeding events of the great tit Parus major from Wytham Woods, Oxfordshire. The effects of inbreeding on fitness were investigated across a life-history continuum, and across environments. I found that close inbreeding (f=0.25) resulted in pronounced inbreeding depression, which acted independently on hatching success, fledging success, and recruitment success, and reduced the number of fledged grand-offspring by 55%. My results therefore suggest that estimates of fitness costs of inbreeding must focus on the entire life cycle. I also show that the variation in the strength of inbreeding depression varies across environments, particularly so the more the environmental variable considered is linked to fitness. These results emphasise the need of using relevant environmental contrasts when investigating inbreeding by environment interactions. I further asked whether individuals involved in matings with relatives differed relative to individuals mating with unrelated partners. I did not find any evidence for clear predictors of inbreeding, and I show that inbreeding depression in our population is entirely independent of any tendency for low quality parental genotypes, or phenotypes, to inbreed. Neither did I find any evidence for active inbreeding avoidance: great tits did not mate less often with kin than expected based on several scenarios of random mating, nor did I find increased rates of extra-pair paternity among birds breeding with relatives. In fact, I observed quite the contrary, as birds mating with kin exhibited a higher than average rate of close inbreeding relative to all scenarios of random mating investigated, showed lower rates of extra-pair paternity and divorce than birds mated to unrelated partners. I hypothesise that cases of occasional inbreeding in this population may result from mis-imprinting or a related process whereby some birds develop particularly strong bonds that are at odds with all predictions of avoiding inbreeding. Finally, I asked to what extent natal dispersal, a behaviour that is often hypothesized to play an important role in avoiding inbreeding, indeed reduces the likelihood of inbreeding. I found that male and female individuals breeding with a relative dispersed over several-fold shorter distances than those outbreeding. This led to a 3.4 fold increase (2.3-5, 95% CI) in the likelihood of close inbreeding relative to the population average when individuals dispersed less than 200m. This thesis demonstrates that inbreeding has deleterious effects on a wild population of birds, occurring throughout an individual’s life, and is of varying strength across environments. My findings strongly support the theory that natal dispersal should be considered as a mechanism of prime importance for inbreeding avoidance.

Genetic, socio-ecological and fitness correlates of extra-group paternity in the European badger (Meles meles)Annavi, Geetha January 2012 (has links)
The evolution of extra-group paternity (EGP) is a contentious issue in evolutionary biology. This thesis examines the factors and adaptive benefits driving EGP in a high-density, group-living population of European badgers (Meles meles). To improve power to assign parentage, I isolated and characterised 21 new polymorphic microsatellite markers. I genotyped 83% of 1410 badger trapped 1987‒2010 using 35 autosomal microsatellite markers. Maternity and paternity were assigned at 80% confidence ca. 82% of individuals. 48% of paternities were extra-group, where 85% were attributable to neighbouring-group males and EGP was detected in 47% of litters; thus badger social group do not correspond with a breeding unit. I tested whether indirect genetic benefits explain these high EGP rates. (1) ‘Good-gene-as-heterozygosity Hypothesis’: Paternal heterozygosity, but not maternal or an individual’s own heterozygosity, associated positively with first-year survival probability. Under benign environmental conditions, cubs fathered by more heterozygous males had a higher first year survival probability. Despite this correlation, the EGP rate per litter correlated with neither average nor maximum within-group heterozygosity of candidate fathers. (2) Fitness benefit Hypothesis: Extra-group offspring (EGO) had lower first-year survival probability and lived 1.3 years less than within-group offspring (WGO). Female WGO produced more litters and offspring over their lifetime than female EGO, whereas male EGO produced more offspring than male WGO. (3) Inbreeding avoidance hypothesis: The EGP rate within a litter increased with greater average pair-wise relatedness between mothers and within-group candidate fathers. No inbreeding depression on first-year survival probability was detected, but small sample sizes limited statistical power. Socio-ecologically, at the litter level, EGP correlated negatively with the number of within-group candidate fathers, and positively with neighbouring-group candidate fathers. In conclusion, EGP in badgers may reduce inbreeding and be maintained in the population through a sex-specific antagonistic selection and indirect genetic benefits may occur when the total fitness benefits of producing extra-group sons outweigh the costs of producing extra-group daughters. These indirect genetic benefits only partially explain the evolution of promiscuity in European badgers, highlighting that evolutionary factors underlying promiscuity remain unclear.

Stratégies de reproduction des mâles et des femelles chez le macaque rhésus (Macaca mulatta)Dubuc, Constance 12 1900 (has links)
Contrairement à d’autres groupes animaux, chez les primates, la hiérarchie de dominance ne détermine pas systématiquement le succès reproductif des mâles. Afin de comprendre pourquoi, j’ai étudié les stratégies de reproduction des mâles et des femelles dans un groupe de macaques rhésus de la population semi-libre de Cayo Santiago (Porto Rico), collectant des données comportementales, hormonales et génétiques pendant deux saisons de reproduction. Les résultats se résument en cinq points.
1. Les nouveaux mâles qui ont immigré dans le groupe d’étude occupaient tous les rangs les plus subordonnés de la hiérarchie de dominance et ont monté en rang suite au départ de mâles plus dominants. Ainsi, l’acquisition d’un rang supérieur s’est faite passivement, en absence de conflits. Par conséquent, les mâles dominants étaient généralement d’âge mature et avaient résidé plus longtemps dans le groupe que les mâles subordonnés.
2. L’accès des mâles aux femelles est en accord avec le « modèle de la priorité d’accès » selon lequel le nombre de femelles simultanément en œstrus détermine le rang de dominance du mâle le plus subordonné qui peut avoir accès à une femelle (p. ex. le mâle de rang 4 s’il y a quatre femelles en œstrus). Bien que les mâles dominants aient eu plus de partenaires et aient monopolisé les femelles de qualité supérieure (dominance, parité, âge) pendant leur période ovulatoire (identifiée grâce au profil hormonal de la progestérone), le rang de dominance n’a pas déterminé le succès reproductif, les mâles intermédiaires ayant engendré significativement plus de rejetons que prédit. Il est possible que ces jeunes adultes aient produit un éjaculat de meilleure qualité que les mâles dominants d’âge mature, leur donnant un avantage au niveau de la compétition spermatique.
3. Les mâles dominants préféraient les femelles dominantes, mais cette préférence n’était pas réciproque, ces femelles coopérant plutôt avec les mâles intermédiaires, plus jeunes et moins familiers (c.-à-d. courte durée de résidence). Au contraire, les femelles subordonnées ont coopéré avec les mâles dominants. La préférence des femelles pour les mâles non familiers pourrait être liée à l’attrait pour un nouveau bagage génétique.
4. L’intensité de la couleur de la peau du visage des femelles pendant le cycle ovarien était corrélée au moment de la phase ovulatoire, une information susceptible d’être utilisée par les mâles pour maximiser leur probabilité de fécondation.
5. Les femelles retiraient des bénéfices directs de leurs liaisons sexuelles. En effet, les femelles en liaison sexuelle bénéficiaient d’un niveau de tolérance plus élevé de la part de leur partenaire mâle lorsqu’elles étaient à proximité d’une source de nourriture défendable, comparativement aux autres femelles.
En somme, bien que les mâles dominants aient bénéficié d’une priorité d’accès aux femelles fertiles, cela s’est avéré insuffisant pour leur garantir la fécondation de ces femelles parce que celles-ci avaient plusieurs partenaires sexuels. Il semble que l’âge et la durée de résidence des mâles, corrélats de leur mode d’acquisition du rang, aient confondu l’effet du rang de dominance. / In contrast to most animal groups, dominance hierarchy does not systematically determine male reproductive success in primates. In order to investigate why, I studied male and female reproductive strategies in a group of free-ranging rhesus macaques on Cayo Santiago, Puerto Rico. I collected behavioural, genetic, and hormonal data during two consecutive mating seasons. My results are summarized below.
1. All new males who immigrated into the study group occupied the lowest-ranking position in the dominance hierarchy and rose in rank as the higher-ranking males left the group. Achieving a higher dominance rank occurred passively, without physical conflict. Thus, dominant males were mature individuals who resided longest in the group.
2. Male access to oestrus females followed the predictions of the ‘priority of access’ model, in which the number of females in oestrus determines the rank of the lowest-ranking male who can access a female (e.g. the fourth ranking male if four females are in oestrus). Even though dominant males obtained more mating partners and monopolised higher quality females (dominance, parity, age) during the ovulation window (as identified using progesterone profiles), dominance rank did not determine reproductive success, as intermediate-ranking males sired significantly more infants than predicted. It is likely that those young, intermediate-ranking adult males produced high quality ejaculate, giving them an advantage in sperm competition.
3. Dominant males preferred high-ranking females, but this preference was not reciprocal; high-ranking females cooperated with younger and less familiar intermediate-ranking males. Conversely, subordinate females cooperated with dominant males. Female preference for non-familiar males (i.e. short residency in the group) may be explained by an attraction to a novel genetic pool.
4. Female facial color intensity during the ovarian cycle was correlated with the timing of the ovulation window. This information may be used by males in order to maximize their fertilisation probability.
5. Consort females enjoyed a higher level of tolerance from their male partner when they were in proximity to a monopolisable food source, compared to other, non-consort females. This suggests that females obtained direct benefits from their sexual consorts.
In conclusion, even though dominant males had priority access to ovulating females in the group, this was insufficient to guarantee fertilisation when females had several sexual partners. It appears that males’ age and length of residency, both correlates of their rank acquisition mode, may have been confounding factors in dominance rank.

Applying the Multiple Constituents’ Model and Social Justice Variables to Determine the Constituents’ Perception of the Virginia Putative Father RegistryJackson, Tracey 08 April 2013 (has links)
A putative father registry represents a legal option for unmarried males who wish to secure legal notice regarding an adoption proceeding for a child they may have fathered. Putative father registries must balance the interests of the putative father against those of the child, the birth mother, and the adoptive parents. This study utilized a framework adapted from the Multiple Constituency Model and used social justice, as indicated by distributive justice and procedural justice, to determine the perceptions among primary constituency groups of the Virginia Putative Father Registry. This research utilized a mixed-methods approach to analyze qualitative data from focus groups in combination with quantitative results from an online survey. The results of the qualitative analysis revealed eight principal findings: First, nearly all putative fathers were unaware of the existence of putative father registry in general, or the Virginia Putative Father Registry in particular. Second, putative fathers were unaware that sex is legal notice in Virginia. Third, once aware of the concept of a putative father registry, the focus group males had positive opinions about putative father registries and the Virginia Putative Father Registry. Fourth, putative fathers preferred to receive notice through the mail regarding an alleged child. Fifth, putative fathers have a negative opinion of providing notice by posting it in newspapers. Sixth, promoting awareness of putative father registries needs to target male audiences and preferably have an interactive component. Seventh, putative fathers expressed strong positive feelings about knowing about a child they may have fathered being placed for adoption. Finally, single male participants in the focus groups were more convinced about the importance of a putative father registry in comparison to married male participants. Quantitative survey data indicated that putative fathers were perceived as the primary constituent group that would benefit the most from a putative father registry. The safeguard variable was significant as it relates to occupation, putative fathers and birth mothers. The study also found that survey respondents indicated that the general public was not aware of putative father registries, and this perception was borne out in focus group results.

Určování rodičovství / Determination of ParenthoodŠilarová, Věra January 2013 (has links)
Determination of Parenthood (Abstract) The determination of parenthood is undoubtedly a very topical issue. There are significant changes which are consequences of modern society approach to the family life as well as of massive progress in the field of medical science and genetics. The development in these areas has brought new concepts such as baby-boxes, assisted reproduction and surrogacy. Now it is up to the legislation to provide rules within the legal framework for these new institutions to steady parental relationships and to secure their protection as well. The aim of this thesis is to familiarize the reader with Czech legal regulation of determination of parenthood by means of its description and analysis. Another aim of the work is to compare this legal regulation with regulation in other countries, in particular in Germany and to find similarities and differences between them. Finally the thesis highlights new institutions within determination of parenthood. This thesis consists of nine chapters which deal with particular parts of its subject-matter. The opening chapter discusses the relationship between a parent and a child both theoretically and historically. Apart from that it also describes legal regulations applicable in the Czech Republic and Germany in the course of time. The second...

Určování rodičovství / Determination of parenthoodKostěncová, Jana January 2014 (has links)
Determination of Parenthood (Abstract) The topic determination of parenthood today is very actual nowadays and it is not possible to neglect its importance. Changes taking place both in the social life of modern times, and in the field of medicine is necessary to constantly reflect and to adapt them to the legal order. Concepts such as assisted reproduction, surrogacy, concealed birth and baby-boxes are a common part of human society and it is not possible to avoid dealing with the situation around them. The aim of this thesis is to summarize the Czech legislation of determination of parenthood, to mention problematic situations that may arise in connection with it and describe possible solutions to these situations. The another aim then is to acquaint the reader with the newly developing institutions, such as assisted reproduction, surrogacy, concealed birth, baby boxes, etc., and analysis of their current legal status supplemented by comparison of legislation in other European and non-European countries, which could serve as inspiration for future development in the Czech legal order. The first chapter deals with family law, family and relationships between parents and children both from a theoretical and historical point of view. The second chapter is devoted to an overview of the most important changes...
