Full textAbstract:
In the common mentality, the conjugal conflict is seen as being similar to scandal, but the scientific literature describes it as the moment that highlights the differences between partners. Therefore, the conflict can invite mediation or, on the contrary, scandal. Fear of the other's reactions, the sustained challenges that define a conflict framework make some partners create strategies to avoid or postpone discussions on marital issues. For a certain category of couples, one of the strategies used to escalate the conflict is temporary separation. The study aims to analyze what the general causes that stimulate temporary separation are and, of course, what the consequences that the decision of temporary separation had on the conjugal couple.

Full textAbstract:
Following divorce or separation, father—child contact is deemed an important influence on child development. Previous research has explored the impact of sociodemographic and attitudinal factors on the amount of contact between fathers and their children following a union dissolution. This article revisits this important question using fathers' reports on a sample of 859 children from newly available survey data. Multilevel random intercept models are used to reassess the influence of child- and father-level factors on the amount of reported contact. Results show that the amount of father—child contact following separation is the product of several factors such as the father's income, conjugal/parental trajectory, and level of satisfaction with existing arrangements.

A preservação dos melhores interesses da criança/adolescente (MICA) nos casos de disputa de guarda e convivência após a separação conjugal é uma tarefa difícil para os atores jurídicos envolvidos nesses casos. Existem alguns fatores que desempenham um papel significativo nesse contexto, ao modificar e/ou moldar o processo legal e o processo de tomada de decisão. Assim, a depender da dinâmica apresentada por esses fatores, o processo de tomada de decisão pode ser mais ou menos difícil. Este artigo apresenta uma revisão narrativa de literatura que teve como objetivo trazer uma visão comparativa entre os processos legais no Brasil e na Inglaterra, bem como questões contextuais envolvidas na disputa de guarda após a separação conjugal. Nesse sentido, são discutidos entendimentos e orientações legais quanto aos MICA, assim como regulações legais relativas à relação parento-filial e divórcio nos dois países. Revela-se que questões legais e culturais podem moldar esses entendimentos e orientações, o que pode levar a diferenças significativas no processo judicial referente à guarda de crianças em ambos os países. Assim, destacam-se e se discutem diferenças culturais e jurídicas relevantes entre o common law inglês e o civil law brasileiro (e.g., concepções sobre ‘guarda’; poder familiar; arranjos de guarda; e o processo judicial em processos de guarda e convivência), as quais podem impactar o processo de tomada de decisão e os melhores interesses da criança.

The article deals with the views of the Fathers of the Church on relations between husband and wife between the end of the first century and the end of the third century, an age that is less studied in this respect, even though it offers good documentation concerning the subject (particularly in the case of Tertullian and Clement of Alexandria). Four themes are considered: 1. adultery and separation; 2. the conjugal debt; 3. the division of tasks between husband and wife; 4. the faith life of the couple. Different opinions and often original points of view are presented in regard to the lawfulness of the second marriage, the culpability of adultery, the value of sexuality in the marriage and the wife’s subordination to her husband.

The book Mediation of family conflicts published by Pro Universitaria Publishing House in December 2020 is the latest publication by the authors Apostu Iulian and Voinea Maria. The paper develops a theoretical approach on the evolution of conjugal structures in the Romanian space, highlighting the resources that define these changes and their effects in terms of functional changes in the family. The originality of the work derives from the new vision that the book brings in this dilemma - mediation or separation – thus synthesizing the sociological and psychological elements about mediation, counseling and therapy. The book is an excellent landmark for those who want to understand the idea of mediation, an action viewed from a threefold perspective: sociological, psychological and of intervention in social work.

Full textAbstract:
The Philippines is one of only two states in the world in which absolute divorce remains largely impossible. Through its family laws, it regulates the marriage, family life and conjugal separation of its citizens, including its migrants abroad. To find out how these family laws interact with those in the receiving country of Filipino migrants and shape their lives, the present paper examines the case of Filipino women who experienced or are undergoing divorce in the Netherlands. Drawing from semi-structured interviews and an analysis of selected divorce stories, it unveils the intertwined institutions of marriage and of divorce, the constraints but also possibilities that interacting legal norms bring in the life of Filipino women, and the way these migrants navigate such norms within their transnational social spaces. These findings contribute interesting insights into cross-border divorces in the present age of global migration.

Full textAbstract:
The aim of this paper is to analyze stepfamily instability in Canada by applying the proportional hazards model to the information collected in the 2001 General Social Survey on Family. More specifically, we examine the effect that the family composition and the type of conjugal union exert on the risk of separation, and test whether the impact of cohabiting union varies over time and between Quebec and the other provinces, depending of its stage of institutionalization. The analysis shows that stepmother families face a lower risk of separation than those formed around a stepfather, and that cohabiting stepfamily couples are more unstable than married ones. The risk of union dissolution among stepfamily couples has increased over time, for married as well as cohabiting partners, but the effect of cohabitation relative to marriage does not appear to significantly differ across periods or regions.
 Zusammenfassung
 Der vorliegende Artikel untersucht die (In)stabilität von Stieffamilien in Kanada. Die Analysen wurden mit dem General Social Survey (GSS) 2001 unter Anwendung der Ereignisdatenanalyse durchgeführt. Von besonderem Interesse waren der Einfluss der Familienkonstellation und die Art der Partnerschaft auf das Trennungsrisiko. Ferner wurde untersucht, wie sich die (In)stabilität von Stieffamilien über die Zeit entwickelt hat. In der kanadischen Provinz Québec gelten nichteheliche Lebensgemeinschaften bereits als vollständig institutionalisiert. Ein weiterer Aspekt dieser Studie war der Vergleich der Entwicklung der québecer Stieffamilien mit denen im restlichen Kanada über die Zeit. Die Ergebnisse zeigen, dass Stiefmutterfamilien ein geringeres Trennnungsrisiko haben als Stiefvaterfamilien und dass Ehen in Stieffamilien stabiler sind als in nichteheliche Lebensgemeinschaften. Ebenso konnte gezeigt werden, dass für beide Partnerschaftstypen das Trennungsrisiko über die Zeit hinweg stark zugenommen hat.

Full textAbstract:
This research had as an objective to understand how paternity constitute itself in the conjugal separation and children guard context, throughout the fatherly figure for understanding that separation historically represents to fathers a moment where they are separated of their children. The research has a qualitative character and seeked to know more about the theme and to do so it‟s been developed semi-structured interviews with seven fathers that were going through the separation process and that for such reason seeked counselling at two juridical practice places that attend the community, in Santa Maria city. After the interviews had been done, a Content Analysis of the same had been applied which made it possible to stablish the following categories: being a father; conjugality and parenthood; guard; loss and suffer; the arising of a new father. The results point out that the conjugal separation has constituted itself as a moment that modifies the paternity exercise, in which meaningful differences occur in before and after mainly in regards to proximity with children and issues involving a relationship with ex-wife. Aspects that point out to inherent conflicts to the end of Conjugality and the maintenance of Parenthood were also identified. Other aspect that had been shown was the expressed desire by the fathers to be present in different moments in the children daily life. In regards to children guard it‟s been noticed a movement of the interviewed fathers in the sense to enlarge their participation. The same way the recognition of the maternal figure was present as that whom is naturally assigned to occupy this place. It can also be mentioned that the interviewed fathers have been seeked to built and rebuilt paternity at all moments, which is characteristical in the contemporary paternity exercise that considers a participative and present father. It‟s understood that the comprehension of this family reality throughout the father‟s point of view allowed to enlarge a glimpse over the phenomenum and made it possible a large understanding of the family‟s relationships dynamics in a current context.<br>Esta pesquisa objetivou conhecer a forma como a paternidade se constitui no contexto da separação e da guarda dos filhos, a partir da perspectiva da figura paterna, entendendo-se que, para o pai, o momento da separação conjugal, historicamente, também caracteriza a separação dos filhos. A pesquisa realizada foi de caráter qualitativo e buscou aprofundar o conhecimento acerca do tema, através de entrevistas semiestruturadas, com sete pais que vivenciavam o processo de separação e por essa razão buscaram atendimento, junto a dois locais de práticas jurídicas que atendem a comunidade, na cidade de Santa Maria, RS. Após a realização das entrevistas efetuou-se a Análise de Conteúdo das mesmas e foram estabelecidas as seguintes categorias: Ser Pai; Conjugalidade e Parentalidade; Guarda; Perdas e Sofrimentos; O Surgimento de um Novo Pai. Os resultados apontam que a separação conjugal tem se constituído como um momento que modifica o exercício da paternidade, onde ocorrem diferenças significativas no antes e no depois, principalmente em relação à proximidade com os filhos e a questões envolvendo o relacionamento com a ex-mulher. São evidenciados aspectos que apontam para conflitos inerentes ao fim da Conjugalidade e a manutenção da Parentalidade. Também se destacou o desejo expresso pelos pais de estarem presentes em diversos momentos na vida cotidiana dos filhos. Com relação à guarda dos filhos, percebeu-se um movimento por parte dos pais entrevistados no sentido de ampliar sua participação. Da mesma forma, esteve presente o reconhecimento da figura materna como aquela que está naturalmente designada para ocupar este lugar. Destaca-se ainda que os pais entrevistados tenham buscado construir e reconstruir a paternidade a todo o momento, características contemporâneas no exercício da paternidade, com um pai mais presente e participativo. Entende-se que a compreensão desta realidade familiar a partir do ponto de vista do pai, permitiu ampliar o olhar sobre o fenômeno e possibilitou um maior entendimento da dinâmica das relações familiares no contexto atual.

Full textAbstract:
This present study aimed to investigate the comprehension and the fantasies of children
related to the marital separation from their parents, contextualizing them with the established
parental relationship. Therefore, a qualitative exploratory study was taken, the research was
done by a study of multiple cases with three families having children of six years old, and
whose parents have been divorced for not longer than two years, at the moment of this
research. In order to collect the data with the children, the following projective tests were
used: Fables Test – pictorial version and the procedure of Family Cartoons with Stories. The
parents were individually interviewed for a Sociodemographic Data Interview and Interview
about Marital Separation and Children. The main reference while examining the data was the
content analysis. Based on the data received, it was possible to perceive differences on the
perception of the children towards the meaning that parental relationships took on the postdivorce
context. Two participants stated that parents were destined a position characterized by
affection, whilst three of them said the mother had a conflictive position. In such way, on this
study, on the eyes of the child the mother figure was understood by the children as source of
safety, replacing the care. Related to the fantasies of the children on their parents post-divorce
scenario, the fantasy of aggression dislocated to the environment prevailed and the fantasy of
family aggression as well. There could be also pointed the fantasies of abandonment and
death, showing the impact of the children in relation to the marital separation. It could be
comprehended that the possible consequences for the children who had its parents separated
are shown through emotional disorder, yet, the quality of the affection among the parents
figure and the children acts as a mediator when great changes are faced, in the case of a
separation, characterizing the emotional disorder of the children as temporary or expected to
the moment of crisis the family experienced. In this way, it is emphasized the need of
listening to the children on the marital separation process, enabling a space for distress,
doubts and fantasies to be freely expressed. Even though there is connection, affection, and
concern from the parents the marital separation occurrence can make the children feel fear
and anxiety, since they are found in a situation passive over happenings prior to the decision
of separation.<br>O presente estudo objetivou investigar a compreensão e as fantasias das crianças acerca da
separação conjugal de seus pais, contextualizando-as nas relações parentais estabelecidas.
Para tanto, realizou-se um estudo exploratório qualitativo composto por um estudo de casos
múltiplos com três famílias de crianças com seis anos, cujos pais estavam separados
conjugalmente há no máximo dois anos, no momento da pesquisa. Para o levantamento de
dados com as crianças, foram utilizados os seguintes instrumentos projetivos: Teste das
Fábulas – versão pictórica e o procedimento de Desenhos de Família com Estórias. Os pais
foram acessados individualmente para uma Entrevista de Dados Sociodemográficos e uma
Entrevista sobre a Separação Conjugal e os Filhos. A referência central na análise dos dados
foi a análise de conteúdo. Com base nos dados, foi possível perceber diferenças na percepção
das crianças a respeito dos significados que as relações parentais assumiram no contexto do
pós-divórcio. Para dois dos participantes, aos pais foi destinada uma posição caracterizada
pela afetividade, ao passo que para três deles a figura das mães ocupava uma posição de
conflito. De modo singular, neste estudo, para uma criança a figura materna foi compreendida
pelos filhos como continente, ocupando o lugar do cuidado. Com relação às fantasias das
crianças no contexto pós-divórcio de seus pais, foram predominantes a fantasia de agressão
deslocada para o ambiente e a fantasia de agregação familiar. Foram presentes também as
fantasias de abandono e de morte, sinalizando o impacto da separação conjugal para os filhos.
Entende-se que as possíveis repercussões para a criança da separação dos pais podem se
manifestar através de desorganizações emocionais, no entanto a qualidade do apego entre as
figuras parentais e as crianças atua como mediadora no momento de grandes mudanças, que
se constitui a separação, caracterizando a desorganização emocional da criança como
transitória ou esperada para o momento de crise que a família vivenciou. Desta forma,
ressalta-se a necessidade de realizar uma escuta da criança no processo de separação dos pais,
viabilizando um espaço para vazão de angústias, dúvidas e fantasias. Uma vez que mesmo
com o envolvimento, afeto e preocupação dos pais o evento da separação conjugal pode gerar
medo e ansiedade na criança, pois ela se encontra em uma posição passiva sobre os eventos
posteriores à decisão de separação.

Full textAbstract:
A literatura sobre separação e recasamento indica que tais eventos são fontes de estresse para toda a família, especialmente quando os filhos passam por um momento de transição ecológica, tal com a entrada no primeiro ano, quando são exigidas, tanto das crianças quanto dos pais, novas habilidades para lidar com as demandas do novo contexto. A partir do Modelo Bioecológico do Desenvolvimento Humano, os objetivos do estudo foram: a) comparar as práticas parentais de mães de famílias nucleares, de famílias monoparentais e recasadas em transição recente e de famílias monoparentais e recasadas estáveis; b) comparar as habilidades sociais, os problemas de comportamento e a competência acadêmica das crianças das diferentes famílias; c) comparar os recursos do ambiente das diferentes configurações familiares que podem contribuir para o desempenho escolar das crianças; d) investigar possíveis preditores das habilidades sociais, dos problemas de comportamento e de competência acadêmica. Participaram da pesquisa 160 mães (33 que estavam casadas, 33 que estavam separadas há menos de três anos e 33 separadas há mais de três anos, 31 que estavam recasadas há menos de três anos e 30 recasadas há mais de três anos), cujos filhos passavam pela transição para o primeiro ano do ensino fundamental em cinco escolas públicas municipais. As 22 professoras das crianças participaram como informantes. Os dados foram coletados com as mães individualmente nas suas residências ou locais de trabalho; responderam a um questionário sobre caracterização familiar, a um inventário de práticas parentais, a um inventário de habilidades sociais e de problemas de comportamento, a um inventário de recursos do ambiente familiar e a um questionário sobre o nível socioeconômico. Em seguida, foram coletados os dados com as professoras das crianças cujas mães atenderam aos critérios de inclusão. As professoras responderam a um inventário de habilidades sociais, de problemas de comportamento e de competência acadêmica. Os resultados das análises de variância indicaram que, comparadas às demais famílias, as mães de famílias nucleares apresentaram mais práticas parentais positivas, mais recursos do ambiente familiar e seus filhos apresentaram mais habilidades sociais de autocontrole e cooperação com pares e menos problemas de comportamento. Já as famílias monoparentais em transição recente em relação às outras, apresentaram menos recursos do ambiente familiar e as crianças pertencentes a essas famílias apresentaram menos habilidades sociais e mais problemas de comportamento. As análises de regressão indicaram que as práticas parentais negativas e a qualidade da relação da criança com o pai biológico foram as variáveis que tiveram maior poder preditivo sobre as habilidades sociais, os problemas de comportamento e a competência acadêmica das crianças, nos ambientes familiar e escolar. Para as avaliações das mães, essas variáveis contribuíram para explicar de 48% a 61% da variância dos comportamentos e da competência acadêmica das crianças no modelo final de predição, enquanto que para as avaliações das professoras, os valores ficaram entre 9% e 17%. Destaca-se que, para as mães e para as professoras, as crianças, independentemente de terem passado por transições familiares, apresentaram muitas habilidades sociais e não se diferenciaram quanto à competência acadêmica. Tais resultados sinalizam recursos individuais que podem funcionar como fatores de proteção.<br>The theory on separation and remarriage indicates that such events are sources of stress for the whole family, especially when children are undergoing ecological transition such as entering the first year, when new skills are required of both children and parents for dealing with the demands of the new context. Taking into account the Bioecological Model of Human Development, the study aimed: a) to compare the parental practices of mothers in nuclear, single-parent, remarried families in recent transition and single-parent and remarried stable families, b) to compare the social skills, behavior problems and academic competence of children from different families, c) to compare the home environment resources of different family configurations which may contribute to the academic performance of the children, d) to investigate possible predictors of social skills and behavior, academic competence problems. The participants were 160 mothers (33 mothers were from nuclear families, 33 from single-parent families separated for less than three years, 33 from single-parent families separated for more than three years, 31 from remarried families for less than three years and 30 from remarried for more than three years) whose children attended the first year of elementary public school. The 22 teachers of the children participated as informants. Data were collected through individual interviews with the mothers in their homes or workplaces. Mothers answered a questionnaire about family characteristics, an inventory of parental practices, an inventory of social skills and behavior problems, an inventory of home environment resources and a questionnaire of socioeconomic status. Then the data were collected with the teachers of children whose mothers met the inclusion criteria. The teachers answered to an inventory of social skills, behavior problems and academic competence. The results of variances analysis indicated that mothers from nuclear families had more positive parental practices, and they had more home environment resources. The analysis also indicated that children from nuclear families had more social skills of self-control and cooperation with peers and had less behavior problems than children and mothers from other families. Mothers from families which recently become single-parent had less home environment resources. The children from these families also had less social skills and had more behavior problems than children and mothers from other families. Regression analysis indicated that negative parental practices and the quality of the relationship between child and biological father were the variables with more predictive power about social skills, behavior problems and academic competence of children in family and in school environment. According to the mothers, these variables contributed to explain 48% to 61% of the variance in behavior and academic competence of children in the final model prediction. To the teachers ratings, the values were between 9% and 17%. Globally, the study highlights the importance of the fact that, for mothers and teachers, children from different families had many social skills and dont differ in terms of academic competence. These results indicate that individual resources should function as protective factors.

O presente trabalho teve como objetivo a compreensão da separação amorosa vivenciada pela mulher de meia idade relacionada ao processo de individuação através de um trabalho realizado em grupo vivencial sob o enfoque da Psicologia Analítica. O método utilizado na pesquisa foi qualitativo sob a perspectiva simbólico arquetípica. Foram realizados oito encontros de grupo com sete participantes na faixa etária de quarenta a cinqüenta e cinco anos que estavam vivenciando uma separação amorosa. No grupo foram utilizados recursos expressivos, contos e mitos para favorecer a elaboração simbólica. A partir do material coletado observou-se uma grande diversidade de experiências em relação à perda como sentimentos de tristeza, solidão, desamparo, raiva, desejos de vingança, sensação de vazio e desorganização. Um tema comum manifestado pelas participantes foi a sensação de perda de identidade no relacionamento anterior ou em decorrência da separação. Identificou-se que esta perda estava associada a conteúdos inconscientes projetados no parceiro e na conjugalidade que ainda não haviam sido reintegrados à consciência. Verificou-se que em alguns casos a identidade estava alicerçada no vínculo simbiótico mantido com o parceiro. Reconhecer a raiva que estava na sombra do relacionamento, recolher as projeções depositadas no parceiro e ter que enfrentar a solidão se revelaram como oportunidades de diferenciação necessárias ao processo de individuação. Na compreensão dos dados, foi utilizado o referencial de mitos e contos para estabelecer algumas amplificações e analogias. Alguns padrões arquetípicos femininos mostraram estar ativados ou negligenciados na psique das participantes: a traição acionou uma Hera raivosa e vingativa em algumas mulheres, enquanto Afrodite parecia abandonada pelo desinteresse manifestado por algumas participantes para novos relacionamentos. Por outro lado a separação constelou arquétipos de deusas mais independentes em algumas mulheres que investem em trabalho e estudos. Observou-se que a temática da descida ao mundo inferior expressa nos mitos de Inana e de Core-Perséfone era constelada na vivência depressiva de algumas participantes, uma experiência necessária à elaboração do luto e ao enraizamento no Self feminino simbolizado pelo encontro com a deusa escura reprimida na cultura patriarcal. O grupo vivencial se mostrou eficaz para favorecer a elaboração do luto pela perda amorosa através da criação de um espaço ritual, permitindo a constelação de uma nova coniunctio. Os recursos expressivos e os contos e mitos utilizados facilitaram a expressão simbólica das participantes e mobilizaram as forças curativas da psique para iniciar a cicatrização das feridas ocasionadas pela perda. Constatou-se no grupo uma apropriação da própria trajetória de vida possibilitando assumir a responsabilidade pelo processo de individuação. São sugeridos novos estudos e o desenvolvimento de trabalhos em grupos vivenciais de mulheres e também de homens para lidar com a separação amorosa em consultórios e instituições de saúde, visando contribuir para a área de relações de gênero.<br>This thesis sought to understand the separation from a love relationship as experienced by middle-aged women related to the individuation process through experiential group work in the focus of Analytical Psychology. The method used in the research was qualitative, under a symbolic archetypal perspective. Eight group meetings were held with seven participants aged from forty to fifty-five who were undergoing separation from love relationships. Expressive resources, tales and myths were used in the group in order to favor the symbolic development. The material gathered showed a large diversity of experiences in relation to the loss, such as feelings of sadness, solitude, distress, anger, wishes of revenge, a feeling of emptiness and derangement. A common matter expressed by the participants was the feeling of loss of identity in the past relationship or as a result of the separation. It was identified that this loss was associated to unconscious contents projected in the partner and in the conjugality that had not yet rejoined their consciousness. It was verified that, in some cases, the identity was grounded on the symbiotic relationship had with the partner. To recognize the anger that was in the shadows of the relationship, to bring in the projections deposited in the partner and have to face solitude revealed to be opportunities of differentiation that are necessary for the individuation process. The referential of myths and tales was used in the understanding of the data, in order to establish some expansions and analogies. Some feminine archetypal standards were shown to be activated or neglected in the psyche of the participants: betrayal turned some women into an angry and vengeful Hera, while Aphrodite looked abandoned by the lack of interest for new relationships expressed by some participants. On the other hand, the separation constellated archetypes of more independent goddesses in some women who invest on their career and education. It was noted that the thematic of the descent to the underworld expressed in the myths of Inanna and Core-Persephone was constellated on the depressive life experience of some participants, a necessary experience for the elaboration of mourning and rooting into their feminine Self, symbolized by the meeting with the dark goddess repressed in the patriarchal culture. The experiential group was shown to be efficient to favor the elaboration of mourning for the loss of their love mate through the creation of a ritual space, allowing the constellation of a new coniunctio. The expressive resources and tales and myths used facilitated the symbolic expression and mobilized the healing forces of the psyche to start the healing of the wounds caused by the loss. The group demonstrated an appropriation of their own trajectories of life, allowing them to take responsibility for the individuation process. New studies are suggested, as well as the development of experiential group work with women and man to handle the separation from love relationships in clinical settings and health institutions, seeking to contribute to the gender relationship area.

Full textAbstract:
Dissertação de Mestrado em Psicologia Legal<br>O presente trabalho de investigação centra-se na mediação familiar, enquanto processo que poderá, em caso de separação/ divórcio, e em alternativa ao sistema judicial, ajudar os pais, com filhos menores, a dinamizarem estratégias que facilitem, por um lado, a sua co-parentalidade e, por outro, a reorganização da nova família binuclear emergente. A mediação familiar, comparativamente com outros países europeus, é uma área pouco explorada e dinamizada ao nível nacional.
Este estudo, de natureza exploratória, tem como principal objectivo determinar a percepção do efeito da mediação familiar, nomeadamente ao nível da satisfação dos clientes (pré-mediados, mediados sem acordo e mediados com acordo) que recorreram ao Gabinete de Mediação Familiar e avaliar em que medida a decisão final influencia essa mesma satisfação. Com este propósito, foi construído um questionário, em três versões, adaptadas à fase processual em que cada cliente terminou o processo. A aplicação dos questionários foi feita, através de correio ou e-mail, a 100 clientes que recorreram ao Gabinete de Mediação Familiar no ano de 2004, após prévio consentimento dos participantes (via telefone). Dos clientes que participaram no estudo. 48 estiveram em processo de pré-mediação, 21 em processo de mediação, mas não alcançaram acordo final e 31 estiveram em mediação e alcançaram um acordo final.
Os resultados apontam, em todas as variáveis avaliadas, para uma maior satisfação dos clientes que estiveram em processo de mediação e que alcançaram acordo final. Verificaram-se diferenças significativas e muito significativas entre os três grupos, quando comparados ao nível dos itens de satisfação, tendo-se observado que a variável acordo final influencia favoravelmente a satisfação da população estudada.
Na discussão dos resultados são levantadas diversas questões para reflexão, sendo, finalmente, sugeridas algumas recomendações práticas.

Previous issue date: 2016-03-31<br>This work aims to analyze press, intelectuals and social actors' positioning about marital separation, through narratives and practices. The research timeframe begins in 1917, when 1916 civil code was promulgated. The first Brazillian civil code instituted the word "separation" instead of "divorce", used by the 1890 matrimonial code. Furthermore, the civil code ratified the parental power and introduced the married woman as a relatively powerless subject. Thus, we studied how the narratives were built, aiming to define the husbands and married women's social roles according to the models established by 1916 civil code. Around the 30's, the feminist movemente emerges in Recife, the Pernambuco's Federation for Female Progress and the Brazillian Feminist Crusade. Thereby, we'll analyze both movements to understand if there was a favorable or not-so positioning about marital separation, since the civil code workes as a moral and social regulation to women mainly. So, we studied the separation, marriage annulment and alimony lawsuits to investigate how social actors experienced Brazillian law practices and the established social behaviors for husbands and wives. This work demands to do a counterpoint between the narratives and practices established on a civil code that legitimated behaviors settled on promoting sexists and unequal model conducts for husbands and wives. This research's contribution, based on gender relations studies, allows us to understand which way the social construction, in history, influenced men and women's unequal roles maintenance and propagation.<br>O presente trabalho tem como objetivo analisar por meio das narrativas e práticas o posicionamento da imprensa, dos intelectuais e dos atores sociais a respeito da separação conjugal. O marco temporal de pesquisa tem início no ano de 1917, ano em que o Código Civil de 1916 é promulgado. O primeiro Código Civil brasileiro instituiu o termo desquite ao invés da palavra divórcio, utilizado pelo Código Matrimonial de 1890. Além disso, o Código Civil ratificou o Pátrio Poder, e inseriu a mulher casada como um sujeito relativamente incapaz. Desse modo, analisamos, por meio dos periódicos da época, como as narrativas foram construídas, visando definir os papéis sociais de maridos e mulheres casadas em consonância com os modelos estabelecidos pelo Código Civil de 1916. Por volta dos anos 30 do século XX, emerge o movimento feminista na cidade do Recife, a Federação Pernambucana pelo Progresso Feminino e a Cruzada Feminista Brasileira, assim, analisaremos ambos os movimentos a fim de compreender se houve um posicionamento favorável ou não às separações conjugais, Visto que o Código Civil funcionava como um regulador social e moral, principalmente para as mulheres. Por conseguinte, nos debruçamos sobre os processos de desquite, anulação de casamento e ação de alimentos, a fim de investigar como os atores sociais vivenciaram as práticas da legislação brasileira e dos comportamentos socialmente estabelecidos para maridos e esposas. O presente trabalho, assim, procura realizar um contraponto entre as narrativas e as práticas estabelecidas a partir de um Código Civil que legitimou comportamentos assentados sobre o biológico, promovendo, assim, modelos de condutas sexistas e desiguais para maridos e mulheres. A contribuição desta pesquisa, baseada nos estudos das relações de gênero, nos permite compreender de que maneira a construção social, ao longo da história, influenciou na manutenção e reprodução dos papéis ainda desiguais entre homens e mulheres.

Full textAbstract:
A vida em sociedade, sobretudo a vida em família, é fonte de conflitos interpessoais, que surgem muitas vezes por dificuldades de comunicação entre as pessoas. Para resolver seus conflitos, e frente às suas dificuldades de comunicação, é bastante comum as pessoas delegarem a decisão sobre as suas vidas a uma terceira pessoa, que institucionalmente em nossa sociedade é o juiz de Direito, acarretando assim a judicialização dos conflitos. A mediação é um método que tem como principal objetivo restaurar e fortalecer a boa comunicação entre as partes em litígio e, para tanto, utiliza-se do princípio da autonomia da vontade dos mediados, para que esses, por meio do diálogo, busquem conjuntamente a resolução para seus conflitos, evitando delegá-los a uma terceira pessoa. O mediador é um terceiro imparcial que auxilia as pessoas a se comunicarem, sem decidir ou oferecer soluções para o conflito. Ao se restaurar uma boa comunicação, espera-se que o acordo passe a ser a consequência lógica do diálogo, o que é muito importante para a área jurídica, pois pode significar um processo a menos no Judiciário. É importante frisar que a mediação não se confunde com terapia, embora dela possam surgir efeitos terapêuticos. Os objetivos da presente pesquisa foram analisar quais conceitos da Psicologia em geral, e da Psicanálise em particular, podem ser úteis no trabalho de mediação, bem como aprofundar a discussão sobre diferenças e semelhanças entre terapia e mediação. Com o intuito de se alcançar os objetivos propostos, foram entrevistados três mediadores reconhecidos na área, por meio de entrevistas semidirigidas, e observadas três reuniões de mediação, duas com as mesmas partes em conflito. Os resultados foram analisados com base na hermenêutica psicanalítica. Como contribuições da Psicanálise, pode-se destacar a possibilidade do uso da contratransferência por parte do mediador, para ampliar a compreensão do conflito entre as partes; a importância da escuta; o princípio de que tão importante quanto o que se diz é o que motiva a dizer; a compulsão à repetição; o fato de o sintoma dos filhos poder estar ligado ao conflito dos pais. Um resultado não previsto, e que merece particular atenção, é a presença de certa psicologização dos conflitos na mediação, reduzindo-se as características do litígio ao âmbito psicológico, bem como o perigo de os mediadores agirem como normalizadores, ao focarem e dirigirem a conversa para o que julgam que precisa ser acordado e como deve ser a repartição das responsabilidades pelo casal em relação aos seus filhos. Entende-se que esse papel cabe ao juiz de Direito, que tem esse poder, e não aos mediadores<br>Life in society, especially family life, is a source of interpersonal conflicts that often arise due to difficulty in communication between people. To resolve conflicts, and facing difficulty in communication, it is quite common for people to delegate the decisions about their lives to a third person, which institutionally in our society is the court judge, thus leading to the judicialization of conflicts. Mediation is a method which aims to restore and strengthen good communication between the parties in dispute and, therefore, uses the principle of autonomy of will on the mediated so that they, through dialogue, can jointly seek the resolution to their conflicts, to avoid delegating them to a third party. The mediator is an impartial third party who helps people communicate without deciding or offering solutions to the conflict. By restoring good communication, it is expected that an agreement becomes the logical consequence of the dialogue, which is very important for the legal department, since it can mean one process less in the Judiciary. It is important to stress that mediation should not be confused with therapy, although therapeutic effects may arise from it. The objectives of this study were to analyze which concepts from Psychology in general, and Psychoanalysis in particular, might be useful in mediation work, as well to deepen the discussion about the differences and similarities between therapy and mediation. In order to achieve the proposed objectives, three mediators recognized in the field were interviewed in semi-structured interviews, and three mediation meetings were observed, two with the same parties in conflict. The results were analyzed based on psychoanalytic hermeneutics. As contributions from Psychoanalysis, it can be highlighted the possible use of countertransference on the part of the mediator to broaden the understanding of the conflict between the parties; the importance of listening; the principle that as important as what is said is what motivates the saying; the compulsion for repetition; the fact that the symptom of the children can be linked to the parental conflict. An unforeseen result, and which deserves particular attention, is the presence of some psychologizing of conflicts in mediation, reducing the characteristics of the dispute to the psychological level, as well as the risk of the mediators acting as normalizers, by focusing and directing the conversation to what they think to be a necessary agreement and to how responsibilities should be divided by the couple in relation to their children. It is understood that this role belongs to the court judge, who has that power, and not to the mediators

Full textAbstract:
The definition of family as a conjugal group consisting of parents and children living in the same household is in the process of a profound reworking, one that includes the constellation of family life that exists around the world. Increased migration and mobility have challenged traditional notions of what constitutes a family, yet much mainstream research relies on past notions of a cohesive unit under one domicile. Many families today are separated across distance and maintain ties in a multitude of ways. And although researchers have increasingly paid attention to this new picture of the family, much of this work has focused on transnational families separated in the context of overseas economic migration. In fact, family separation and long-distance parenting result from a multitude of reasons undertaken in various circumstances. This volume presents work from scholars who collectively show reasons that motivate parenting across distance, how families cope with separation and maintain ties, the impact of separation on family members, and how family is redefined and reconfigured in these various settings. By better understanding how we parent from a distance, this volume synthesizes ideas of kinship, relationships, and bonding and helps readers broaden their own ideas of parenting and family life.

In Large Meteorite Impacts and Planetary Evolution VI. Geological Society of America, 2021. http://dx.doi.org/10.1130/2021.2550(27).
Full textAbstract:
ABSTRACT Structural analysis of overturned metasedimentary strata of the lower Witwatersrand Supergroup in the inner collar of the Vredefort Dome reveals the presence of tangential folds and faults associated with the 2.02 Ga impact. The folds are distinct from previously identified subradially oriented, vertical to plunging-inclined, gentle folds that are interpreted as the products of convergent flow (constriction) during the initial stages of central uplift formation. The tangential folds comprise disharmonic, open, asymmetric, horizontal to plunging-inclined anticline-syncline pairs with centripetally dipping axial planes and right-way-up intermediate limbs. They display centripetal-down vergence (anticline radially outward of the syncline) that is consistent with steep inward-directed shear of the overturned strata. We attribute this kinematic pattern to subvertical collapse of the Vredefort central uplift during the latter stages of crater modification. The folds are cut by pseudotachylite-bearing steep to vertical tangential faults that display center-down slip of &lt;10 m up to ~150 m. Both the tangential folds and the faults suggest that the large-scale overturning of strata related to outward collapse of the Vredefort central uplift was accompanied by a component of inward-directed collapse via layer-parallel shearing and folding, followed by faulting. Subradially oriented faults with conjugate strike separations of 1–2 km in the NNE collar of the dome suggest penecontemporaneous tangential extension of the inner collar rocks. This evidence indicates that second-order structures in the metasedimentary collar of the Vredefort Dome preserve a complex, multistage record of evolving strain associated with both initial convergent and upward flow (constriction) related to central uplift rise and later divergent and downward flow (flattening) linked to its collapse, and that centripetally directed collapse features may be important components of the structural inventory of very large central uplifts.

Full textAbstract:
Determination of heat loads is a key issue in the design of gas turbines. In order to optimize the cooling, an exact knowledge of the heat flux and temperature distributions on the airfoils surface is necessary. Heat transfer is influenced by various factors, like pressure distribution, wakes, surface curvature, secondary flow effects, surface roughness, free stream turbulence and separation. All these phenomenon are challenges for numerical simulations. Among numerical methods, Large Eddy Simulations (LES) offers new design paths to diminish development costs of turbines through important reductions of the number of experimental tests. In this study, LES is coupled with a thermal solver in order to investigate the flow field and heat transfer around a highly loaded low pressure water-cooled turbine vane at moderate Reynolds number (150 000). The meshing strategy (hybrid grid with layers of prisms at the wall and tetrahedra elsewhere) combined with a high fidelity LES solver gives accurate predictions of the wall heat transfer coefficient for isothermal computations. Mesh convergence underlines the known result that wall-resolved LES requires discretisations for which y+ is of the order of one. The analysis of the flow field gives a comprehensive view of the main flow features responsible of heat transfer, mainly the separation bubble on the suction side that triggers transition to a turbulent boundary layer and the massive separation region on the pressure side. Conjugate heat transfer computation gives access to the temperature distribution in the blade, which is in good agreement with experimental measurements. Finally, given the uncertainty on the coolant water temperature provided by experimentalist, uncertainty quantification allows apprehending the effect of this parameter on the temperature distribution.

Full textAbstract:
Computational and experimental investigations on a flat circular disk are reported with a constant heat flux imposed on its bottom surface and a shower head of air jets impinging on the top surface. The shower head consists of a central jet surrounded by four neighboring perimeter jets. Lamp black flow visualization technique and computations using shear stress transport (SST) κ-ω turbulence model are employed to describe the complex interaction of the wall jets and the associated flow structure. Thermochromic liquid crystal measurement technique is used for surface temperature measurement. The formations of saddle point, nodal point of attachment, nodal point of separation, flow separation line and the up-wash flow are identified. It is observed that the flow topology is practically independent of Reynolds number within the investigated range but is significantly altered with the spacing between the jet orifice and the target surface. A strong correlation between the Nusselt number and the pressure distribution is noticed. Local variation of heat transfer rate with varying plate spacing to jet diameter ratio is significant but its effect on the area weighted average heat transfer rate is small. When compared with a single jet of equal mass flow rate and Reynolds number, the shower head jets provide higher heat transfer rate but require more power for pumping.

We investigate the numerical prediction of film cooling effectiveness of a two-dimensional gas turbine endwall for the cases of conjugate and adiabatic heat transfer models. Further, the consequence of various turbulence models employed in the computation are investigated by considering various turbulence models: ‘RNG’ k-ε model, Realizable k-ε model, Standard k-ω model, ‘SST’ k-ω model, and ‘RSM’ model. The computed flow field and surface temperature profiles along with the film effectiveness for one and two cooling slots at different injection angles and blowing ratio of one are presented. The results show the strong effect of the conjugate heat transfer on the film effectiveness compared to the adiabatic and analytically derived formulae and show that turbulence model used significantly affects the film effectiveness prediction when separation occurs in the film hole and some level of jet lift-off is present.

Full textAbstract:
Film cooling performance is typically quantified by separating the external convective heat transfer from the other components of the conjugate heat transfer that occurs in turbine airfoils. However, it is also valuable to assess the conjugate heat transfer in terms of the overall cooling effectiveness, which is a parameter of importance to airfoil designers. In the current study, adiabatic film effectiveness and overall cooling effectiveness values were measured for the pressure side of a simplified turbine vane model with three rows of showerhead cooling at the leading edge and one row of body film cooling holes on the pressure side. This was done by utilizing two geometrically identical models made from different materials. Adiabatic film effectiveness was measured using a very low thermal conductivity material, and the overall cooling effectiveness was measured using a material with a higher thermal conductivity selected such that the Biot number of the model matched that of a turbine vane at engine conditions. The theoretical basis for this matched-Biot number modeling technique is discussed in some detail. Additionally, two designs of pressure side body film cooling holes were considered in this study: a standard design of straight, cylindrical holes and an advanced design of “trenched” cooling holes in which the hole exits were situated in a recessed, transverse trench. This study was performed using engine representative flow conditions, including a coolant-to-mainstream density ratio of DR = 1.4 and a mainstream turbulence intensity of Tu = 20%. The results of this study show that adiabatic film and overall cooling effectiveness increase with blowing ratio for the showerhead and pressure side trenched holes. Performance decreases with blowing ratio for the standard holes due to coolant jet separation from the surface. Both body film designs have similar performance at a lower blowing ratio when the standard hole coolant jets remain attached. Far downstream of the cooling holes both designs perform similarly because film effectiveness decays more rapidly for the trenched holes.

There are different characters of air flow in a conventional gas turbine blade cooling channel. These flow characters; including high streamline curvature caused from 180 degree bends, sequential flow separations caused from rib turbulators and pin-fin structures are analyzed separately with available commercial software for different turbulence models and validated against reliable experimental data from open literature. Also coupled conjugate heat transfer analyses on NASA C3X vane, which has only radial holes through blade span for cooling, are conducted with the same turbulence models. The accuracy information gathered from all these analyses; each interested with a single character of air and coupled conjugate heat transfer are put together and applied to a conjugate numerical analysis of internally cooled (VKI) LS-89 turbine blade. Internal cooling scheme which is applied to (VKI) LS-89 turbine blade encompassed the aforementioned flow characters and analyses are performed under realistic conditions. Because of the high temperature values occurring at realistic conditions, thermal conductivity and specific heat capacity of air and metal (Inconel 718) are modeled as temperature dependent material properties instead of using constant values. Conducted research revealed that 4 eqn. V2-f turbulence model gives similar results compared to the 2 eqn. Realizable k-e, k-w SST turbulence models for 180 degree bend and rib turbulator cases. However, at NASA C3X vane analyses V2-f turbulence model results are far more accurate than other two turbulence models in the manner of heat transfer coefficient and surface temperature distribution.

Abstract In gas processing, boosting, and gathering applications, gas-liquid separator equipment (typically referred to as a scrubber) is placed upstream of each reciprocating compressor stage to remove water and hydrocarbon condensates. However, field experience indicates that liquids are often still present downstream of the separation equipment. When liquids are ingested into the reciprocating compressor, machinery failures, some of which are severe, can result. While it is generally understood that liquid carryover and condensation can occur, it is less clear how the multiphase fluid moves through equipment downstream of the scrubber. In this paper, mechanisms responsible for liquid formation and carryover into reciprocating compressors are explored. First, the effects of liquid ingestion on reciprocating compressors reported in the open literature are reviewed. Then, the role of heat and pressure loss along the gas flow path is investigated to determine whether liquid formation (i.e., condensation) is likely to occur for two identical compressors with different pulsation bottle configurations. For this investigation, conjugate heat transfer (CHT) models of the suction pulsation bottles are used to identify regions where liquid dropout is likely to occur. Results of these investigations are presented. Next, liquid carryover from the upstream scrubber is considered. Multiphase models are developed to determine how the multiphase fluid flows through the complex flow path within the pulsation bottle. Two liquid droplet size distributions are employed in these models. Descriptions of the modeling techniques, assumptions, and boundary conditions are provided.

Full textAbstract:
If a high voltage is applied to a pair of electrodes immersed in a certain dielectric fluid, a strong microjet occurs between the electrodes. This is called the ECF (electro-conjugate fluid) effect. However, the mechanism of the occurrence of such a microjet has not been clarified yet. As a first step, we here attempt to clarify this mechanism by means of a laser visualization technique with a PIV analysis tool. From this analysis tool, we have obtained flow field solutions and also evaluated the maximum velocity of a microjet as functions of the magnitude of an applied voltage, the separation of a pair of electrodes, etc. Some important results obtained here are summarized as follows. The average maximum velocity decreases linearly with decreasing values of the gap between the electrodes and also with increasing values of the magnitude of an applied voltage in a surface liquid area. Moreover, the average maximum velocity has a tendency to decrease gradually with increasing values of the depth of the electrodes immersed in an electro-conjugate fluid.

Computational Fluid Dynamics (CFD) predictions of film cooling performance for gas turbine airfoils are an important part of the design process for turbine cooling. Typically, industry relies on the approach based on Reynolds Averaged Navier Stokes equations, together with a two-equation turbulence model. The Realizable k-ε (RKE) model and the Shear Stress Transport k-ω (SST) model are recognized as the most reliable. Their accuracy is generally assessed by comparing to experimentally measured adiabatic effectiveness. In this study, the performances of the RKE and SST models were evaluated by comparing predicted and measured thermal fields in a turbine blade leading edge with three rows of cooling holes, positioned along the stagnation line and at ±25°. Predictions and measurements were done with high thermal conductivity models which simulated the conjugate heat transfer effects between the coolant flow and the solid. Particular attention was placed on the thermal fields along the stagnation line, and immediately downstream of the off-stagnation line row of holes. Conventional evaluations in terms of adiabatic effectiveness were also carried out. Predictions of coolant flows at the stagnation line were significantly different when using the two different turbulence models. For a blowing ratio of M = 2.0, the predictions with the SST model showed coolant jet separation at the stagnation line, while the RKE predictions showed no separation. Experimental measurements showed that there was coolant jet separation at the stagnation line, but the actual thermal fields obtained from experimental measurements were significantly different from that predicted by either turbulence model. Similar results were seen for predicted and measured thermal fields downstream of the off-stagnation row of holes.

The laminated cooling or multi-layered impingement-effusion cooling, which originates from combustion liner cooling, is believed to be an advanced and promising gas turbine blade cooling technique. Previous authors’ works have found that surface curvatures have different influences on overall cooling effectiveness of laminated cooling. To determine the optimal configuration of laminated cooling for various surface curvatures respectively, the conjugate heat transfer approach that has been validated by the experimental data was employed to study numerically the effects of streamwise incline angles (including 15, which was 20 degree for flat plate and concave surface, 30, 60 and 90 degree) on overall cooling effectiveness with different surface curvatures. The results show that the shallower film holes restrain the liftoff of the coolant ejection, and lead to a higher overall cooling effectiveness. However, shallower injection angle causes higher pressure loss. The relationship between injection angle and overall cooling effectiveness for different curvature is illustrated in the paper. The results indicate that shallower injection angle provides more than 10% improvement of cooling effectiveness compared to that of 90° injection angle for flat plate, concave surface and convex surface with smaller curvature at high blowing ratio. But for convex surface with large curvature, blowing ratio of 0.7 to 0.9 is better for overall cooling effectiveness, and shallower injection angle has little effect on cooling effectiveness. Moreover, additional pressure loss occurs to shallower injection angle because of the serious flow separation.

Abstract Aerodynamic cooling of hot components/surfaces such as those encountered in gas turbine engines is needed to avoid premature failure of parts due to thermo-mechanical stresses. An effective way of achieving this cooling is through the exchange of heat via effusion/film cooling holes on the hot surfaces. The gases absorb heat as they flow through the cooling holes and also by forming a protective layer of relatively cool gases near the hot surface. Modeling these processes allow for durable design of components and computational simulations offer a complementary way to design new parts or enable performance assessment of the existing parts at new operating conditions. However, in order to perform numerical simulations of heat transfer through effusion holes, the heat conduction through the solid liner and the convection from the gas phase must be coupled considering all the relevant length and time scales. The time scale separation between the solid and the gas phase makes this prohibitively expensive for large scale computations. In applications involving hundreds of effusion holes, resolving the geometry of each effusion hole along with the primary flow (with typically larger length scales) is very challenging. In the current work, we overcome the difficulties associated with the resolution of cooling holes by employing a local source method (Andreini et al, J. Eng. Gas Turb. Power, 2014) to model the heat transfer to the walls. This method is assessed in a canonical configuration based on experiments performed by Gustafsson (Gustaffson, Ph.D. Thesis, 2001). Large Eddy Simulations (LES) coupled with conjugate heat transfer (CHT) models are used in this study. Simulations that resolve the flow passages explicitly using mesh both in the fluid and the solid domains, were used to validate the fidelity of grid resolution, turbulence models and other simulation parameters in predicting velocity fields and wall temperature data. Although, resolving all the effusions passages provides the most accurate results, it is not practical in real applications. Hence, a local source model is employed to model the heat transfer that happens in the cooling-hole passages. In this method, the effusion passage is not resolved (using a mesh) and the mass transfer across the cooling hole passage is prescribed as an injection-extraction boundary condition. The heat transfer at the fluid-solid interface of the cooling-hole passage is also modeled based on Nusselt number correlations available in the literature. This modeling procedure enables simulations with flexible mesh topologies that can be generated at a relatively low cost in comparison to the fully resolved mesh configurations. The local source method is assessed and validated using the available experimental data. The results show that the meshes which resolve the penetration depth in the solid and which conform at the solid-gas interface provide better prediction of the wall temperatures.

This Letter considers probability density functions (pdfs) involving products of the complex amplitudes observed at two points (which may, in general, involve separations in space, time, or frequency) in conditions of fully saturated scattering. First, the pdf is derived for the product of the complex amplitude at one point with the conjugate of the complex amplitude at another point. It is shown that the real and imaginary parts of this product each have a variance gamma pdf. Second, expressions are derived for several joint pdfs involving complex amplitude products and powers at two points.
