Abstract Inquiring into the impact of DNA technology on Brazilian family law,, through the consultation of legislation, jurisprudence and specific legal briefs concerning paternity disputes, we map out trends over the past thirty years. We show how, after a moment of original skepticism, genetic evidence appears to dominate the legal scene, rendering personal testimony irrelevant. However, with growing concern about men who use a negative test result to disclaim their paternal status, this testimony is once again needed to clarify whether or not the man originally believed the child was his blood-related offspring. Finally, we look at a recent period, showing how reactions against the "real biological truth" have spawned a new juridical category-socio-affective paternity-that, spreading well beyond paternity tests, is altering some basic tenets of family law.
P.T. Anderson's latest film, There Will Be Blood, represents both a culmination and a crisis within his career-long investigation of the limits of paternity and the solace of surrogacy. By pressing that ongoing antagonism to a kind of absurd extreme in Daniel Day Lewis' performance, this paper argues that Anderson undoes it and leaves his future possible direction unclear. Further, by battening on the corpus of Upton Sinclair's 1926 novel, Anderson introduces a political unconscious that his rigorous reduction to a family drama cannot fully contain or defuse.
The Swedish State Institute for Blood Group Serology is a central government laboratory handling all blood typing in paternity cases in Sweden, each year testing 1,500-2,000 cases using about 13 polymorphisms. Of the accused men, 35%-40% are nonfathers, but in one-man cases (about 78% of all cases), approximately 75% are the true fathers. Exclusions appear to be distributed as expected from allele frequencies, and the paternity probability of nonexcluded men is assessed with a Bayesian approach. Some cases are retested in extended investigations which raise theoretical exclusion capability from about 87% to about 99%. Both the results of extended investigations and the theoretical consideration of the distribution of paternity probabilities support the use of such positive statistical evidence for the attribution of paternity.
Today, there is consensus that the current system of allocating and enforcing child support obligations does not work well for disadvantaged families, most of which are nonmarital. Nonmarital children are less likely to have support orders established than marital children, and they are much less likely to experience full payment. In this article, we report data on child support awards and enforcement associated with a sample of paternity actions brought in 2008 or 2010 in St. Joseph County, Indiana. We found that child support practice in St. Joseph County promotes limited contact between children and their absent fathers, nonpayment of prior support obligations, and the accrual of arrears that can never be paid. These results strongly support recent changes in federal child support regulations and programs that postdate the orders in our study. Our results also demonstrate both the need for additional reforms and the difficulties that lie ahead as the states begin to grapple with applying the new standards.
Enfocando o impacto da tecnologia do DNA no direito de família brasileiro, pela análise de leis, jurisprudência e processos particulares lidando com disputas de paternidade, mapeamos tendências de mudança ao longo dos últimos trinta anos. Mostramos como, após um momento de ceticismo inicial, a evidência genética parece dominar o cenário legal, tornando os depoimentos pessoais irrelevantes. Entretanto, com a atenção crescente dirigida para homens que usam um resultado negativo para refutar seu status paterno, a importância de depoimentos volta para esclarecer se o pai registral originalmente acreditava ou não que tinha um vínculo consanguíneo com seu filho. Finalmente, olhamos para um período recente, rastreando como reações contra a "verdade real" da biologia geram uma nova categoria jurídica – paternidade socioafetiva – que, estendendo-se muito além dos testes de paternidade, está alterando alguns princípios básicos do direito da família. ; Centrándonos en el impacto de la tecnología del ADN en el derecho de familia brasileño, analizando las leyes, la jurisprudencia y las demandas particulares relacionadas con disputas de paternidad, trazando tendencias cambiantes en los últimos treinta años.

AbstractWe conducted the first experimental tests of the impact of men's access to paid parental leave on anticipated well‐being among heterosexual men and women in the United States. Participants read a news article reporting that paid paternity leave was either likely or unlikely in the United States in the near future, completed a future life‐brainstorming task designed to make this scenario more salient, and reported anticipated outcomes pertaining to well‐being (predicted relationship satisfaction, positive and negative emotions, and life satisfaction). Results from an online sample (Experiment 1, N = 694) revealed that both men and women predicted more positive outcomes when they believed paid paternity leave would (vs. would not) exist. In contrast, results from students (Experiment 2, N = 199) revealed that women predicted better outcomes in the leave (vs. no leave) condition, while men predicted consistently positive outcomes regardless of condition. Looking at the interaction the other way, paternity leave closed a gender gap in anticipated well‐being favoring men. Exploratory analyses revealed that students anticipated increased relationship gender equality in division of labor as a result of paternity leave, but only in gender counter‐stereotypic domains (i.e., paid work outside the home for women; unpaid childcare and housework for men).
RESUMEN. La legislación española contempla únicamente como formas de filiación la natural y la adoptiva. En la etapa preconstitucional la investigación de la paternidad no estaba permitida. La paz familiar y la protección del matrimonio impedían que se pudiera demandar una filiación biológica no reconocida. Con ocasión de la CE, y de reformas legislativas posteriores, se implantó en España un sistema de acciones que permiten la constatación oficial de una filiación natural, a través de un pronunciamiento judicial. En la actualidad, ese sistema de acciones aún impone una serie de controles y limitaciones al acceso a la investigación de la paternidad. Entendemos que ha llegado el momento de ampliar esas garantías del derecho a la libre investigación de la filiación biológica. Para ello, será necesario realizar una serie de reformas legislativas que pasen por realzar y dar un valor absoluto a la llamada prueba biológica de ADN. Esta prueba equipara la verdad biológica con la jurídica Así lo proponemos en el presente trabajo. De igual forma, se requieren modificaciones en la legitimación de esas acciones, así como elevar a rango de Ley criterios jurisprudenciales plenamente consolidados por nuestros Tribunales. ; ABSTRACT. The Spanish legislation contemplates only as natural and adoptive forms of filiation. In the preconstitutional stage the investigation of paternity was not allowed. Family peace and the protection of marriage made it impossible to claim unrecognized biological filiation. On the occasion of the EC, and subsequent legislative reforms, a system of actions was implemented in Spain that allow the official confirmation of a natural filiation, through a judicial pronouncement. At present, this system of actions still imposes a series of controls and limitations on access to paternity research. We understand that the time has come to extend these guarantees of the right to free investigation of biological filiation. To do this, it will be necessary to carry out a series of legislative reforms that go on to enhance and give an absolute value to the so-called biological DNA test. This test equates the biological truth with the legal Thus we propose it with the present work. Likewise, changes in the legitimacy of these actions are required, as well as raising to the rank of Law, jurisprudential criteria fully consolidated by our Tribunals.

Although the birth of twins has always attracted attention, there are no known genetic or environmental factors that can determine the birth of monozygotic (MZ) twins. And even for dizygotic (DZ) twins, genetic influences are not completely understood. A previous study from our group has shown that the C allele of polymorphism rs1042522 in the TP53 gene was more frequent in the mothers of twins than in the mothers of singletons in a small village in South Brazil. In order to clarify whether this was an isolated factor, we performed a population-based, observational case-control study. Samples were selected from a state-funded program of paternity investigation. Samples were considered cases when two of the children had the same date of birth, whereas controls were those samples in which at least two children were born in different dates. The first subsequent sample fulfilling control criteria was included after each case. From 2007 to 2013, 32,661 records were searched and 283 (0.9%) twins were found (119 MZ and 164 DZ). Genotypic and allele frequencies were not different between mothers of twins or mothers of singletons. However, mothers of MZ twins showed a higher frequency of GG genotype and lower frequency of the C allele when compared to mothers of DZ twins. Also, the proportion of MZ twins (42%) was higher than usually reported (30%). Finally, the proportion of twins found in this study seems to be more realistic, as this sample was allegedly not from users of assisted reproduction techniques.

Evolutionary theory guides an investigation of foster parent selection in two northern Thai villages with different biosocial environments: one village has high levels of labour migration and divorce, and growing numbers of parental death due to HIV/AIDS, while the other village has lower migration, divorce and parental mortality levels. Focus groups examine mothers' and fathers' motivations and ideals regarding foster caretaker selection, and quantitative family surveys examine real fostering outcomes: specifically, the laterality (matrilateral versus patrilateral) and genetic distance of the foster caretakers of all ever-fostered children in these two villages. As predicted, in environments of high marital stability and paternity certainty, parents seem to prefer close genetic kin from either side as foster parents for their children. In low marital stability and paternity certainty environments, parents trust their own lateral kin, regardless of genetic distance, over close genetic kin from the other side. The striking exception to this pattern, however, occurs in the case of parental death, in which case children are fostered to the deceased parent's kin, regardless of the child's sex or other factors. In general, the foster parents for girls are selected with more care, reflecting the daughter/female preference expected in traditionally matrilineal, matrilocal societies. An ordered decision-making pathway for foster parent selection is proposed, taking into consideration the key factors of (a) the circumstances driving the fostering decision, (b) the gender of the child, (c) the gender of the key decision-making parent, and (d) the degree of marital and population fluidity (and subsequent paternity certainty) in the village.
The present study attempts to reveal Unamuno's conception of family as conceived in his theoretical, literary and autobiographical writings. As a historical and hermeneutical work, it will focus on the written work of the author who is the ultimate object of the present investigation. Thus, the sociological horizon that gave rise to Unamuno´s reflection, when considered, can only find its theoretical sense in the fact that it allows the clarification of the thinker's philosophical and educational position. In order to clarify his educational thought, we chose to previously define Unamuno´s conception of family so as to, based on their characterization, we can understand his peculiar conceptions of maternity and paternity. Despite its current decontextualization, and if properly targeted, such peculiar conceptions can recover the traits or spiritual dimensions of contemporary education, which requires the formation of the intimate self and the public self of the younger generations, i.e. their ethical-normative and political-legal education, which, nowadays, has been demanded of school. ; El presente estudio intenta desvelar la concepción unamuniana de familia tal como nuestro autor la concibe en sus escritos teóricos, literarios y autobiográficos. Siendo un trabajo histórico-hermenéutico, se centrará en la obra escrita del autor que constituye el objeto último de la presente investigación. Bien, por ello el horizonte sociológico que dio origen a la reflexión unamuniana, siendo considerado, solo halla su sentido teórico en cuanto que permite la clarificación de la posición filosófico-educativa de Unamuno. Con vistas a clarificar su pensamiento educativo, optaremos por definir a priori su concepción de familia para que, apoyados en su caracterización, podamos comprender sus peculiares concepciones de maternidad y paternidad que, pese a su actual descontextualización, pueden recuperar, si debidamente enfocadas, los rasgos o dimensiones espirituales de la educación contemporánea, que exige la formación del yo-íntimo ...
The present investigation is guided to prove that the article 367° of the Peruvian Civil Code have deficiencies in its writing, because it prescribes that the action to answer the paternity corresponds the husband. Then it adds that their heirs and their ascendancies can begin it if he has died before being conquered the term (90 days) pointed out in the article 364° of the same body of laws, the one which expressed a restrictive and very questionable character, because our Civil Code follows the same outline of the French Civil Code, however, in other legislations, its proven that the husband cannot only answer the paternity, but also the son and their heirs in wide form, for we are intending a modification of the referred article, in agreement with the compared law. After the analysis of the doctrine and national and compared legislation, we have established that there is really a legal hole, for what is necessary to make the necessary amendments to our Civil Code, in order to improve the legislation on the investigation problem. ; La presente investigación está orientada a probar que el artículo 367° del Código Civil Peruano tiene deficiencias en su redacción, porque prescribe que la acción para contestar la paternidad corresponde al marido. Luego agrega, que sus herederos y sus ascendientes pueden iniciarla si él hubiese muerto antes de vencerse el plazo (90 días) señalado en el artículo 364° del mismo cuerpo de leyes, el cual expresa un carácter restrictivo y muy cuestionable, pues nuestro Código Civil sigue el mismo esquema del Código Civil Francés, sin embargo, en otras legislaciones, se comprueba que no sólo el marido puede contestar la paternidad, sino también el hijo y sus herederos en forma amplia, por ello estamos proponiendo una modificación del referido artículo, en concordancia con el derecho comparado. Luego del análisis de la doctrina y legislación nacional y comparada, hemos establecido que realmente hay un vacío legal, por lo que es necesario hacer las enmiendas necesarias a nuestro Código Civil, a fin de mejorar la legislación sobre el problema de investigación.
Context Translocation has become a widely used method to restore wildlife populations following extirpation. For some species, such as lekking grouse, which breed at traditional mating grounds, reproduction is linked to culturally established geographic locations. Cultural centres are lost upon extirpation, making restoration into otherwise rehabilitated habitats especially challenging. The process by which species with culturally dependent reproduction sometimes become re-established is poorly understood and merits investigation to improve conservation strategies. Historically, population restoration of North American lekking grouse (Tympanuchus spp. and Centrocercus spp.) via translocation has yielded poor results, in part because translocation sites lack leks, culturally determined breeding locations for which breeding adults form a high degree of philopatry. Columbian sharp-tailed grouse (Tympanuchus phasianellus columbianus; CSTG) occurs in <10% of its historic range, but the existence of rehabilitated historic habitat provides for the potential of population restoration via translocation.
Aims We reintroduced CSTG to vacant habitat in north-central Nevada, USA, from 2013 to 2017, with concordant goals of promoting females to nest and males to lek. We tested the utility of performing artificial insemination (AI) on females before translocation and we conducted paternity analyses to understand male reproduction.
Methods We monitored females for the effects of AI on nest initiation, nest survival and egg fertility. We used post-hatch extra-embryonic membranes and other tissues to evaluate paternity of chicks produced at the restoration site.
Key results Artificial insemination had no effect on female survival or nest initiation, and did not fertilise any eggs within nine sampled clutches (n=102 eggs). Most paternity was attributable to male residents that had survived for ≥1 year at the restoration site before the arrival of translocated females.
Conclusions Artificial insemination neither aided nor harmed female reproduction. A small number of translocated, resident adult males sired reproduction following female release.
Implications The presence of resident males at restoration sites may be more likely to result in post-translocation reproduction than is pre-translocation AI. Restoring CSTG to vacant habitat should focus on translocating females into suitable nesting habitat while simultaneously ensuring that reproductively capable males are available within or adjacent to the nesting habitat.
Despite current debate over the paternal role, fatherhood is a relatively new area of investigation in literary, historical and cultural studies. The contributors to this illustrated, interdisciplinary volume - one of the first extended investigations of paternity in 19th century Britain and its empire - penetrate the stereotype of the Victorian paterfamilias to uncover intimate and involved, authoritarian and austere fathers. Finding surprising precursors of the 'new man' and the 'lone father', Trev Lynn Broughton and Helen Rogers provide an essential overview of changing ideologies and practices of fatherhood as the family acquired its distinctively modern form. Gender and Fatherhood in the Nineteenth Century: - Offers nuanced re-readings of artistic and literary representations of domesticity, investigations of fathering at home and at work, and of legal, political and religious discourses, suggesting that fatherhood generated more anxiety and debate than previously acknowledged. - Explores how traditional conceptions of paternal authority worked to accommodate the 'cult of motherhood'. - Examines how paternal power was embedded in social institutions. - Shows how models of social fatherhood provided powerful men with a means of negotiating their relationship with working-class men and colonized subjects. As these innovative essays demonstrate, the history of fatherhood can illuminate our understanding of class, society and empire as well as of gender and the family. Together they form an indispensable resource for anyone studying Victorian fatherhood as part of a history, literature, art, social or cultural studies course
