Caregiver Responses to the Language Mixing of a Young Trilingual

The situation once described by Hoffmann (1985), in which children grow up exposed to three languages from an early age, is a reality for an increasing number of families. In Europe – as elsewhere – greater mobility is leading to greater numbers of mixed-language couples (Piller 2002), and, by extension, multilingual families. For such families, questions concerning the acquisition and maintenance of three or more languages in a natural environment are of direct relevance. Researchers in bilingualism have already pointed out the importance of social context for the acquisition of two languages in childhood, focusing in particular on the quantity and quality of exposure to the languages (De Houwer 1990; Döpke 1992; Okita 2002; Lanza 2004) or the prestige of the languages (Lambert 1977). In this paper, I will make use of the insights gained by such researchers and test them in a trilingual setting. The paper will focus mainly on one aspect, namely the conversational style of parents and caretakers. The data come from research being carried out in Switzerland and consist of 33 interviews with multilingual families, as well as case studies of two trilingual children. The findings attest to the importance of conversational style, but at the same time indicate that a number of further factors are also of great significance.

Crystal structure of yeast initiation factor 4A, a DEAD-box RNA helicase

The eukaryotic translation initiation factor 4A (eIF4A) is a member of the DEA(D/H)-box RNA helicase family, a diverse group of proteins that couples an ATPase activity to RNA binding and unwinding. Previous work has provided the structure of the amino-terminal, ATP-binding domain of eIF4A. Extending those results, we have solved the structure of the carboxyl-terminal domain of eIF4A with data to 1.75 Å resolution; it has a parallel α-β topology that superimposes, with minor variations, on the structures and conserved motifs of the equivalent domain in other, distantly related helicases. Using data to 2.8 Å resolution and molecular replacement with the refined model of the carboxyl-terminal domain, we have completed the structure of full-length eIF4A; it is a “dumbbell” structure consisting of two compact domains connected by an extended linker. By using the structures of other helicases as a template, compact structures can be modeled for eIF4A that suggest (i) helicase motif IV binds RNA; (ii) Arg-298, which is conserved in the DEA(D/H)-box RNA helicase family but is absent from many other helicases, also binds RNA; and (iii) motifs V and VI “link” the carboxyl-terminal domain to the amino-terminal domain through interactions with ATP and the DEA(D/H) motif, providing a mechanism for coupling ATP binding and hydrolysis with conformational changes that modulate RNA binding.

Struggling, Coping, And Thriving: Sense-Making In Stepfamily Couples' Narratives About Coparenting

The term coparenting implies a bioparental dyad that often excludes the stepparent's role in sharing parenting across joint-custody households. Focusing solely on this dyad also precludes gaining an understanding of how stepfamily couples manage together the communication and sharing of parental responsibilities with the parent(s) in the shared children's other home. In a departure from this bioparental dyad-focused approach, this study locates the stepfamily couple at the center of an inquiry into managing coparenting across households. This mixed methods design study included in-depth interviews of 32 stepfamily couples whose narratives about coparenting were analyzed using grounded theory methods. Forty-one percent of stepparents engage in direct coparenting communication, sometimes manifested as the coactive approach identified in this study. Stepfamily couples also involve the stepparent indirectly in coparenting communication, through the conferred and consultative approaches. As well, the couples' narratives about coparenting identify them as either united, where they share the experience, or divided, where coparenting is reserved exclusively for the bioparent to manage. The stepfamily couples' narratives about significant coparenting experiences revealed that they experience and make sense of coparenting as 1) struggling, 2) coping, or 3) thriving. No significant relationship was found between marital satisfaction and experiencing coparenting as strugglers, copers or thrivers. Grounded theory analysis of these narratives also reflects the four dichotomous dimensions of 1) regard-disregard, 2) decency-duplicity, 3) facilitation-interference, and 4) accommodation-inflexibility. Significant incidents located along these dimensions contribute to the stepfamily couples' identification as struggling, coping, or thriving in coparenting. Experiences on the extreme ends of the dichotomous dimensions generate positive and negative turning points for the coparenting interactions and relationships. As well, experiences on the negative end of the dimensional poles can present challenges for the stepfamily couples. Finally, a synthesis of the findings related to the dichotomous dimensions generates a theory of shared parenting values expectancy.

Brief of Amici Curiae Scholars of the Constitutional Rights of Children in Support of Petitioners in Obergefell v. Hodges

Supreme Court precedent establishes that the government may not punish children for matters beyond their control. Same-sex marriage bans and non-recognition laws (“marriage bans”) do precisely this. The states argue that marriage is good for children, yet marriage bans categorically exclude an entire class of children – children of same-sex couples – from the legal, economic and social benefits of marriage. This amicus brief recounts a powerful body of equal protection jurisprudence that prohibits punishing children to reflect moral disapproval of parental conduct or to incentivize adult behavior. We then explain that marriage bans punish children of same-sex couples because they: 1) foreclose their central legal route to family formation; 2) categorically void their existing legal parent-child relationships incident to out-of-state marriages; 3) deny them economic rights and benefits; and 4) inflict psychological and stigmatic harm. States cannot justify marriage bans as good for children and then exclude children of same-sex couples based on moral disapproval of their same-sex parents’ relationships or to incentivize opposite-sex couples to “procreate” within the bounds of marriage. To do so, severs the connection between legal burdens and individual responsibility and creates a permanent class or caste distinction.

A Defensive "stand-by reaction" at Critical Moments of the Reproductive Life Cycle

Investigation about the psychological experiences of the reproductive life cycle showed that in critical moments special reactions may happen. These reactions seem to be defensive in nature, are set in motion in order to promote some kind of emotional protection and are performed in two opposite directions: a) a decreasing of the contact with aggressive impulses and b) an increasing of the use of rationalization and denial of frustrating situations. Examples of those rearrangements were observed at samples of: 1) pregnant women in obstetric high-risk consultation, 2) infertile couples waiting for infertility consultations and 3) pregnant women waiting for amniocentesis results. These data seem to be in accordance with the classical psychological points of view: a) gestation should be considered as a period of protection, b) during pregnancy a “primary maternal preoccupation” (Winnicot, 1958) emerges leading to the mobilization of all resources available for pregnant women and c) along gestational development psychological changes show how flexible maternal functioning may become. What was not expected is that in the absence of pregnancy, infertile couples should behave very similarly to what it is observed when pregnancy is in danger or when medical problems about the mother’s or the baby’s health arise in the horizon. Due to its “freezing” consequences upon emotional development we propose that this kind of reaction will be designated as “stand-by reaction”.

Client discourses on the process of seeking same-sex couple counselling

How same-sex couples manage the process of seeking help for their relationships is an under-researched area. Twelve semi-structured interviews were conducted with 16 people who had engaged in same-sex couple counselling, and were analysed using discourse analysis. The ways in which the couples positioned themselves as part of a 'minority group', or part of a generic group of couples struggling with relationship issues, impacted on how they discussed seeking help. We conclude that counsellors and psychotherapists need to be aware of the ways in which couples construct their relationships, and mindful of the tricky navigations around similarity to, and difference from, different-sex relationships. The impact of this on couples seeking therapeutic help is considered. © 2013 Taylor & Francis.

Metabolism Regulates the Fate and Function of T Lymphocytes

Proper balancing of the activities of metabolic pathways to meet the challenge of providing necessary products for biosynthetic and energy demands of the cell is a key requirement for maintaining cell viability and allowing for cell proliferation. Cell metabolism has been found to play a crucial role in numerous cell settings, including in the cells of the immune system, where a successful immune response requires rapid proliferation and successful clearance of dangerous pathogens followed by resolution of the immune response. Additionally, it is now well known that cell metabolism is markedly altered from normal cells in the setting of cancer, where tumor cells rapidly and persistently proliferate. In both settings, alterations to the metabolic profile of the cells play important roles in promoting cell proliferation and survival.

It has long been known that many types of tumor cells and actively proliferating immune cells adopt a metabolic phenotype of aerobic glycolysis, whereby the cell, even under normoxic conditions, imports large amounts of glucose and fluxes it through the glycolytic pathway and produces lactate. However, the metabolic programs utilized by various immune cell subsets have only recently begun to be explored in detail, and the metabolic features and pathways influencing cell metabolism in tumor cells in vivo have not been studied in detail. The work presented here examines the role of metabolism in regulating the function of an important subset of the immune system, the regulatory T cell (Treg) and the role and regulation of metabolism in the context of malignant T cell acute lymphoblastic leukemia (T-ALL). We show that Treg cells, in order to properly function to suppress auto-inflammatory disease, adopt a metabolic program that is characterized by oxidative metabolism and active suppression of anabolic signaling and metabolic pathways. We found that the transcription factor FoxP3, which is highly expressed in Treg cells, drives this phenotype. Perturbing the metabolic phenotype of Treg cells by enforcing increased glycolysis or driving proliferation and anabolic signaling through inflammatory signaling pathways results in a reduction in suppressive function of Tregs.

In our studies focused on the metabolism of T-ALL, we observed that while T-ALL cells use and require aerobic glycolysis, the glycolytic metabolism of T-ALL is restrained compared to that of an antigen activated T cell. The metabolism of T-ALL is instead balanced, with mitochondrial metabolism also being increased. We observed that the pro-anabolic growth mTORC1 signaling pathway was limited in primary T-ALL cells as a result of AMPK pathway activity. AMPK pathway signaling was elevated as a result of oncogene induced metabolic stress. AMPK played a key role in the regulation of T-ALL cell metabolism, as genetic deletion of AMPK in an in vivo murine model of T-ALL resulted in increased glycolysis and anabolic metabolism, yet paradoxically increased cell death and increased mouse survival time. AMPK acts to promote mitochondrial oxidative metabolism in T-ALL through the regulation of Complex I activity, and loss of AMPK reduced mitochondrial oxidative metabolism and resulted in increased metabolic stress. Confirming a role for mitochondrial metabolism in T-ALL, we observed that the direct pharmacological inhibition of Complex I also resulted in a rapid loss of T-ALL cell viability in vitro and in vivo. Taken together, this work establishes an important role for AMPK to both balance the metabolic pathways utilized by T-ALL to allow for cell proliferation and to also promote tumor cell viability by controlling metabolic stress.

Overall, this work demonstrates the importance of the proper coupling of metabolic pathway activity with the function needs of particular types of immune cells. We show that Treg cells, which mainly act to keep immune responses well regulated, adopt a metabolic program where glycolytic metabolism is actively repressed, while oxidative metabolism is promoted. In the setting of malignant T-ALL cells, metabolic activity is surprisingly balanced, with both glycolysis and mitochondrial oxidative metabolism being utilized. In both cases, altering the metabolic balance towards glycolytic metabolism results in negative outcomes for the cell, with decreased Treg functionality and increased metabolic stress in T-ALL. In both cases, this work has generated a new understanding of how metabolism couples to immune cell function, and may allow for selective targeting of immune cell subsets by the specific targeting of metabolic pathways.

Female employment from the household. Towards a comprehensive analysis of work-life articulation

Research on women’s employment has proliferated over recent decades, often under a perspective that conceptualizes female labour market activity as independent of male presences and absences in the productive and reproductive spheres. In the face of these approaches, the article argues the need to focus on the couple as the unit of analysis of work-life articulation. After referring to the main theoretical arguments that, from a gender perspective within labour studies, have pointed out the relevance of placing the household as the central space for the analysis of the sexual division of labour, the article reviews different empirical contributions that have incorporated such perspective in the international literature. Next, the state of the art in the Spanish literature is presented, before arguing the desirability of applying such framework of analysis to the study of employment and care work in Spanish households, which are at present undergoing major transformations.

Dielectric studies of Liquid Crystal Nanocomposites and Nanomaterial systems.

Liquid crystals (LCs) have revolutionized the display and communication technologies. Doping of LCs with inorganic nanoparticles such as carbon nanotubes, gold nanoparticles and ferroelectric nanoparticles have garnered the interest of research community as they aid in improving the electro-optic performance. In this thesis, we examine a hybrid nanocomposite comprising of 5CB liquid crystal and block copolymer functionalized barium titanate ferroelectric nanoparticles. This hybrid system exhibits a giant soft-memory effect. Here, spontaneous polarization of ferroelectric nanoparticles couples synergistically with the radially aligned BCP chains to create nanoscopic domains that can be rotated electromechanically and locked in space even after the removal of the applied electric field. The resulting non-volatile memory is several times larger than the non-functionalized sample and provides an insight into the role of non-covalent polymer functionalization. We also present the latest results from the dielectric and spectroscopic study of field assisted alignment of gold nanorods.

Strong motion compatible source geometry

Strong motion array records are analyzed in this paper to identify and map the source zone of four past earthquakes. The source is represented as a sequence of double couples evolving as ramp functions, triggering at different instants, distributed in a region yet to be mapped. The known surface level ground motion time histories are treated as responses to the unknown double couples on the fault surface. The location, orientation, magnitude, and risetime of the double couples are found by minimizing the mean square error between analytical solution and instrumental data. Numerical results are presented for Chi-Chi, Imperial Valley, San Fernando, and Uttarakashi earthquakes. Results obtained are in good agreement with field investigations and those obtained from conventional finite fault source inversions.

Kahdestaan kotona : Tutkimus vanhoista pariskunnista

In this study, which pertains to the field of social gerontology and family research, I analyse the meaning of everyday life as perceived by elderly couples living at home. I use the ethnographic approach, with the aim of interpreting meanings from the elderly people s personal point of view and to increase understanding of their way of life. The study deepens our conception of what gives purpose to the everyday life of elderly people. The number of elderly couples is growing and, to an increasing extent, a couple will live and cope together to a ripe old age. Such coping can also be viewed as an important resource for society. Ethnography tries to get close to people's life practices. I examine the day-to-day life of elderly couples based on textual data, which I obtained by visiting the homes of 16 couples in a total of five small municipalities in Southern Finland. The couples had married soon after the war or in the early 1950s. I found that the aspiration towards continuity, which unites the concepts of place and home, housework and a long marriage, is the most important notion connecting the discussion themes. The results show that in the opinion of the elderly, the concept of a good life is intertwined with a long marriage spent at home, as well as its values. Old people find that they lead an independent life if they feel that they can hold on to the key features of their way of life. Elderly couples ability to cope with everyday life involves taking care of housework and other tasks around the home together. This means that they support one another and have common goals and aspirations. Daily tasks provide substance in the lives of elderly couples. Each day has its rhythm, and the pace of this rhythm is set by routine and habits. Satisfaction stems from the fact that you can do something you are good at. The couples have also revised the division of housework. Men have learned to perform new tasks around the house when their wives can no longer manage them by themselves. Some tasks are given up. Day-to-day life at home and around the house provides room for men s participation. Mutual support and care between husband and wife can also protect them from having to resort to outside or official help. Old couples integrate their life experiences and memories, as well as present and future risks and opportunities. They wish to carry on their lives as before, and still think that their present life corresponds with their idea of a good life. Key words: elderly couples, continuity theory of aging, everyday life, social gerontology, family research

Depending on you – A study of spousal care, everyday life and agency The present aim of the aging policy is to promote old peoples´ possibilities to live at their own home. It is also many elderly couples´ own wish. At home a persons spouse is the most natural care giver, if she or he is able to give care. Spousal care means living together, giving and receiving care and interdependency between the spouses. The aim of the policy is to support spousal care by paying financial support to a carer and arrang-ing formal home care services. The purpose of this research is to study the agency of care giving and receiving spouses as care givers and receivers and also as home care service users. The data of the study consist of the interviews of 21 elderly couples. Both spouses were interviewed seper-ately, with the exception of five couples who were interviewed together. In these inter-views a care receiver had difficulties in communicating by speaking and a spouse was her or his interpreter. The study is based on a social constructionistic and a discourse analytical view of con-struction of meanings in human communication. Talking is a social action: people achieve identities, realities, social order and social relationship through talking. In inter-pretating the spouses agency I have used of Harvey Sack´s method of Membership Categorization Device (MCD). The spouses construct social categories which made the meaning of their agency visible. Care changes the routines and actions of everyday life. The couples have to negotiate their duties and rights between each other. Care giving and receiving are both physical and emotional actions. In the end it becomes a part of the couples´ normal life. The pur-pose of couples´ action is to live together as long as possible. They want to strengthen both their own agency and their spouses´ agency. The living together depends on both of them. The spouses decided together what home care services they would like to use and on which conditions they have to use services. Spouses have different kind of agencies as service users which describe their relationship and confidency on formal home care support and services. Services must support the elderly couples´ shared life at home. They cannot be against the conditions on the spousal care. When you want to arrange services to elderly care giving and receiving couples, you have to consider their own wishes and the meanings of their own relationship and shared life.

Reactive Diffusion in the Re-Si System

A study on reactive diffusion is conducted in the Re-Si system. According to the study, ReSi1.8 phase grows with much higher thickness than the Re2Si phase, in the interdiffusion zone of bulk diffusion couples. The activation energy for integrated diffusion of ReSi1.8 is estimated to be 605 +/- 23 kJ/mol. The growth of the Re2Si phase is studied by considering an incremental diffusion couple of Re/ReSi1.8. Analysis based on the calculation of integrated diffusion coefficients indicates the reason underlying the observed high difference between the growth rates of the ReSi1.8 and Re2Si phases.

Quando o legislativo não legisla - : o caso do projeto de lei nº 1151/1195, que disciplina a união civil entre pessoas do mesmo sexo

Analisa as repercussões sociais e os sucedâneos jurídicos à falta de regulamentação em lei de usos e costumes, já incorporados ao modus vivendi da sociedade, de populações de orientação sexual minoritária. Toma-se como paradigma dessa situação, o Projeto de lei nº 1.151/1995, de autoria da ex-deputada federal Marta Suplicy, que visa a instituir a união civil homossexual, reformada depois para parceria civil registrada entre pessoas do mesmo sexo. Tramitando há mais de 13 anos na Câmara dos Deputados, e aprovado por unanimidade pela Comissão Especial que o analisou, aguarda penosamente a apreciação do Plenário daquela Casa de Leis. Por isso, desamparados em suas demandas, os atores sociais envolvidos buscam outros foros onde possam ser ouvidos.

Os crimes no triângulo amoroso: uma discussão psicanalítica historicamente contextualizada a respeito do conceito de violenta emoção no Direito Penal Brasileiro

A presente tese tem o objetivo de promover uma análise sobre a norma penal brasileira que versa sobre a violenta emoção, com base no estudo teórico da ação criminal passional. Tem por objeto de estudos a discussão sobre a temporalidade psíquica da ação que sustenta as distinções no instituto jurídico da violenta emoção apresentada nos artigos 28; 65, III, c; 121 1 e 129 4 do Código Penal Brasileiro. A partir de uma construção genealógica, buscou-se os antecedentes históricos dessas leis, posteriormente, interpretadas à luz de conceitos psicanalíticos e de contribuições da antropologia social acerca do imaginário cultural que sustenta a eclosão e o julgamento de crimes na esfera amorosa. O método de trabalho consistiu em um estudo teórico de caráter dedutivo-construtivo baseado em fontes oriundas de diferentes campos teórico-práticos e também de consultas abertas feitas a juristas e estudiosos da criminologia. As transformações históricas nos julgamentos indicam uma transposição da antiga indulgência em relação aos criminosos ao atual apelo por recrudescimento das penas, demonstrando que justificar ou punir crimes sob a rubrica da violenta emoção ligados à esfera amorosa representa um sintoma atrelado ao contexto social. O conceito de "violenta emoção" está sujeito a reducionismos teóricos, devido à ênfase dada à dimensão da "culpabilidade consciente" no sistema jurídico, ao predomínio de interpretações ligadas aos aspectos psicofisiológicos do ímpeto, bem como à incipiente atenção dada às condições inconscientes culturalmente determinantes do ato criminal violento em casais. Desse modo, o texto dos referidos artigos pode servir indevidamente à diminuição da pena em crimes envolvendo casais, assim como a devida atenuação pode ser desconsiderada quando a/o ré/u sofre de privações sociais e psíquicas prolongadas constitutivas de um mal-estar passional por vezes dissociado do tempo da ação. Com as limitações apontadas, reconhece-se a importância da existência da referência à violenta emoção enquanto uma atenuante criminal genérica e critica-se a sua aplicação como "privilégio" de diminuição de pena em crimes de ímpeto em casais. O estudo psicanalítico historicizado do tema assevera a necessidade de realçar tanto a responsabilidade subjetiva ligada à atualização de um potencial psicopatológico, mas, também, a responsabilidade social em relação aos crimes passionais, enfatizando a importância de se criar alternativas à resposta penal, buscando promover uma leitura e interpretação cuidadosa dos artigos sobre a violenta emoção no sentido de propiciar melhor entendimento da temporalidade inconsciente inerente a esses crimes.
