Group fission in Nilgiri langurs (Presbytis johnii)

During a field study on habituated groups of wild Nilgiri langurs (Presbytis johnii), four cases of group fission were observed which differed markedly from group changes reported in other species of the same genus. All fissions occurred in groups with more than one mature male and roughly coincided with the onset of loud call vocalization by the second mature male group member. As a result of the fission the founder group factions acquired the structure of a onemale group. The filial factions consisted of both mature males and females and occupied, at least temporarily, a part of, or an area adjacent to, the founder group. During fission, the amount of aggressive interactions between the two mature males increased. However, the majority of agonistic interactions involved ritualized threat and intimidation behavior without physical aggression. In at least three cases the two mature males involved in the fission had not joined recently but had lived in these groups for three years or more. Although the presence of all male bands and single males in the two study populations indicate that male replacement by invasive takeovers may occur, it is suggested that in Nilgiri langurs, noninvasive fissions are probably another common mechanism for the foundation and maintenance of bisexual one-male groups.

Transfers of Family Businesses to Non-Family Buyers - The Selling Business Family Perspective

This study focuses on business families and how they handle transitions such as business transfers. It also tries to shift the balance of research away from successions and towards business transfers as a key topic for family business researchers. In addition, it contributes to the family business research field by further highlighting the importance of the various different contributions in the family business from business family members other than the entrepreneurial founder. Based on interviews with both business family members and business brokers, it appears as important for business families who are selling their family business that it is managed in a similar way in the future regardless of the shift in ownership and management. It is also important that the employees can stay with the business. However, employees are seldom regarded as potential buyers of the family business; most preferably, from the point of view of business family members, this should be somebody who is similar to themselves. Business transfers can be lengthy processes, but once the family business is sold, previous owners most often want to leave the family business. This disengagement can be difficult for business family members if they have not managed to build up some other identity outside the family business environment. Money may compensate for the loss in the short run, but something else is needed in the long run, since the management of money is usually not perceived as that interesting. A family business transfer can have great influence on the members of the business family who is selling, and therefore it is suggested that personal due diligence could be of some help when planning the transfer. That tool can help business family members to analyse their own personal situation, but it may also make it easier to understand how the other business family members feel about the forthcoming change. Everyone is influenced in different ways during a family business transfer, and awareness of this fact may make it easier for the whole business family to adjust to their new environment.

Uniparental DNA markers and forensic genetics in Finland

Over the years, a wide range of methods to verify identity have been developed. Molecular markers have been used for identification since the 1920s, commencing with blood types and culminating with the advent of DNA techniques in the 1980s. Identification is required by authorities in many occasions, e.g. in disputed paternity cases, identification of deceased, or crime investigation. To clarify maternal and paternal lineages, uniparental DNA markers in mtDNA and Y-chromosome can be utilized. These markers have several advantages: male specific Y-chromosome can be used to identify a male from a mixture of male and female cells, e.g. in rape cases. MtDNA is durable and has a high copy number, allowing analyses even from old or degraded samples. However, both markers are lineage-specific, not individualizing, and susceptible to genetic drift. Prior to the application of any DNA marker in forensic casework, it is of utmost importance to investigate its qualities and peculiarities in the target population. Earlier studies on the Finnish population have shown reduced variation in the Y-chromosome, but in mtDNA results have been ambiguous. The obtained results confirmed the low diversity in Y-chromosome in Finland. Detailed population analysis revealed large regional differences, and extremely reduced diversity especially in East Finland. Analysis of the qualities affecting Y-chromosomal short tandem repeat (Y-STR) variation and mutation frequencies, and search of new polymorphic markers resulted a set of Y-STRs with especially high diversity in Finland. Contrary to Y-chromosome, neither reduced diversity nor regional differences were found in mtDNA within Finland. In fact, mtDNA diversity was found similar to other European populations. The revealed peculiarities in the uniparental markers are a legacy of the Finnish population history. The obtained results challenge the traditional explanation which emphasizes relatively recent founder effects creating the observed east-west patterns. Uniparentally inherited markers, both mtDNA and Y-chromosome, are applicable for identification purposes in Finland. By adjusting the analysed Y marker set to meet the characteristics of Finnish population, Y-chromosomal diversity increases and the regional differentiation decreases, resulting increase in discrimination power and thus usefulness of Y-chromosomal analysis in forensic casework.

Dissection of the genetic background of childhood onset progressive myoclonic epilepsies

The progressive myoclonic epilepsies (PMEs) are a clinically and etiologically heterogeneous group of symptomatic epilepsies characterized by myoclonus, tonic-clonic seizures, psychomotor regression and ataxia. Different disorders have been classified as PMEs. Of these, the group of neuronal ceroid lipofuscinoses (NCLs) comprise an entity that has onset in childhood, being the most common cause of neurodegeneration in children. The primary aim of this thesis was to dissect the molecular genetic background of patients with childhood onset PME by studying candidate genes and attempting to identify novel PME-associated genes. Another specific aim was to study the primary protein properties of the most recently identified member of the NCL-causing proteins, MFSD8. To dissect the genetic background of a cohort of Turkish patients with childhood onset PME, a screen of the NCL-associated genes PPT1, TPP1, CLN3, CLN5, CLN6, MFSD8, CLN8 and CTSD was performed. Altogether 49 novel mutations were identified, which together with 56 mutations found by collaborators raised the total number of known NCL mutations to 364. Fourteen of the novel mutations affect the recently identified MFSD8 gene, which had originally been identified in a subset of mainly Turkish patients as the underlying cause of CLN7 disease. To investigate the distribution of MFSD8 defects, a total of 211 patients of different ethnic origins were evaluated for mutations in the gene. Altogether 45 patients from nine different countries were provided with a CLN7 molecular diagnosis, denoting the wide geographical occurrence of MFSD8 defects. The mutations are private with only one having been established by a founder-effect in the Roma population from the former Czechoslovakia. All mutations identified except one are associated with the typical clinical picture of variant late-infantile NCL. To address the trafficking properties of MFSD8, lysosomal targeting of the protein was confirmed in both neuronal and non-neuronal cells. The major determinant for this lysosomal sorting was identified to be an N-terminal dileucine based signal (9-EQEPLL-14), recognized by heterotetrameric AP-1 adaptor proteins, suggesting that MFSD8 takes the direct trafficking pathway en route to the lysosomes. Expression studies revealed the neurons as the primary cell-type and the hippocampus and cerebellar granular cell layer as the predominant regions in which MFSD8 is expressed. To identify novel genes associated with childhood onset PME, a single nucleotide polymorphism (SNP) genomewide scan was performed in three small families and 18 sporadic patients followed by homozygosity mapping to determine the candidate loci. One of the families and a sporadic patient were positive for mutations in PLA2G6, a gene that had previously been shown to cause infantile neuroaxonal dystrophy. Application of next-generation sequencing of candidate regions in the remaining two families led to identification of a homozygous missense mutation in USP19 for the first and TXNDC6 for the second family. Analysis of the 18 sporadic cases mapped the best candidate interval in a 1.5 Mb region on chromosome 7q21. Screening of the positional candidate KCTD7 revealed six mutations in seven unrelated families. All patients with mutations in KCTD7 were reported to have early onset PME, rapid disease progression leading to dementia and no pathologic hallmarks. The identification of KCTD7 mutations in nine patients and the clinical delineation of their phenotype establish KCTD7 as a gene for early onset PME. The findings presented in this thesis denote MFSD8 and KCTD7 as genes commonly associated with childhood onset symptomatic epilepsy. The disease-associated role of TXNDC6 awaits verification through identification of additional mutations in patients with similar phenotypes. Completion of the genetic spectrum underlying childhood onset PMEs and understanding of the gene products functions will comprise important steps towards understanding the underlying pathogenetic mechanisms, and will possibly shed light on the general processes of neurodegeneration and nervous system regulation, facilitating the diagnosis, classification and possibly treatment of the affected cases.

Estimating the Threshold Surface Density of Gp120-CCR5 Complexes Necessary for HIV-1 Envelope-Mediated Cell-Cell Fusion

Reduced expression of CCR5 on target CD4(+) cells lowers their susceptibility to infection by R5-tropic HIV-1, potentially preventing transmission of infection and delaying disease progression. Binding of the HIV-1 envelope (Env) protein gp120 with CCR5 is essential for the entry of R5 viruses into target cells. The threshold surface density of gp120-CCR5 complexes that enables HIV-1 entry remains poorly estimated. We constructed a mathematical model that mimics Env-mediated cell-cell fusion assays, where target CD4(+)CCR5(+) cells are exposed to effector cells expressing Env in the presence of a coreceptor antagonist and the fraction of target cells fused with effector cells is measured. Our model employs a reaction network-based approach to describe protein interactions that precede viral entry coupled with the ternary complex model to quantify the allosteric interactions of the coreceptor antagonist and predicts the fraction of target cells fused. By fitting model predictions to published data of cell-cell fusion in the presence of the CCR5 antagonist vicriviroc, we estimated the threshold surface density of gp120-CCR5 complexes for cell-cell fusion as similar to 20 mu m(-2). Model predictions with this threshold captured data from independent cell-cell fusion assays in the presence of vicriviroc and rapamycin, a drug that modulates CCR5 expression, as well as assays in the presence of maraviroc, another CCR5 antagonist, using sixteen different Env clones derived from transmitted or early founder viruses. Our estimate of the threshold surface density of gp120-CCR5 complexes necessary for HIV-1 entry thus appears robust and may have implications for optimizing treatment with coreceptor antagonists, understanding the non-pathogenic infection of non-human primates, and designing vaccines that suppress the availability of target CD4(+)CCR5(+) cells.

La reinserción social de los ex-presidiarios en la Argentina de las primeras décadas del siglo XX : algunos comentarios biográficos sobre Jorge H. Frías, fundador del Patronato de Liberados y Excarcelados de la Capital Federal

Resumen: Este trabajo pretende avanzar sobre una problemática escasamente abordada por la historiografía jurídica y social argentina: la reinserción social de los egresados de las prisiones. Así, partiendo de la utilidad que tienen para la historiografía los estudios biográficos y de instituciones penitenciarias y post-penitenciarias, analizaremos algunos aspectos de la labor profesional de Jorge H. Frías, distinguido jurista, presidente de la Cámara de Apelaciones en lo Criminal y Correccional y fundador en 1918 de la primera institución de reinserción social de la Argentina: el Patronato de Liberados y Excarcelados de la Capital Federal. Esperamos que este breve trabajo contribuya a alentar la realización de otros estudios sobre diferentes aspectos del universo penitenciario argentino (directores de presidios, viajeros penitenciarios, congresos penitenciarios nacionales e internacionales, revistas de los funcionarios de prisiones, etc.) que aún hoy en día permanecen desconocidos.

A metrópole em cena: As metáforas do teatro e do cinema em Cidade de Vidro de Paul Auster e Sinédoque Nova York de Charlie Kaufman

A metáfora do mundo como um palco está presente no imaginário humano há muitos séculos, o que se pode ver nas obras artísticas e filosóficas, de Cícero a Shakespeare: o mundo é representação. O presente estudo propõe-se a analisar interdisciplinamente os desdobramentos das metáforas do teatro e do cinema, na exploração do espaço da metrópole, tendo como corpus o romance Cidade de Vidro, de Paul Auster (1999) e a narrativa fílmica Sinédoque Nova York, de Charlie Kaufman (2008). Para tal, procuramos os teóricos da metáfora, tendo como principal deles Hans Blumenberg, fundador da Metaforologia, Paul Ricoeur e Derrida, em estudos especialmente dedicados a essa figura de linguagem. As metáforas, contudo, se realizam em um determinado espaço, o da metrópole, e para nos guiarmos em seus caminhos, elegemos os estudiosos da nova geografia cultural, dentre os quais Paul Claval, Mathias Le Bossé e Denis Cosgrove. Na correlação da cidade com o teatro, apontaremos a própria história da criação do teatro ocidental como o principal ponto de partida para as ramificações de tal mimetismo. Para o estudo específico do espaço da metrópole, contamos com Walter Benjamin e seus seguidores. Os estudos benjaminianos serão também de vital importância para a compreensão da relação entre cinema e metrópole, relação essa que também foi aclarada pelo questionamento de Nietzsche sobre a verdade. Não foi nossa intenção comparar as obras aqui analisadas em seus planos narratológicos, mas articular dois textos regidos por códigos e procedimentos artísticos parecidos, mas, ainda assim diferentes. Buscamos apontar como as relações teatrais e cinemáticas na metrópole, fragmentada como o próprio homem que nela se perde, provocam uma suspensão da fronteira entre realidade e ficção

O corpo como obra de arte e fundador da experiência estética em MerleauPonty

Este trabalho parte de uma leitura da filosofia de Merleau-Ponty centrada na noção de Corpo como Obra de arte, fundamentando-se no pressuposto de que se trata de um conceito fundamental da fenomenologia contemporânea e da estética. Este trabalho assume a tarefa de mostrar que, Merleau-Ponty discute a questão do corpo como obra de arte não com os pressupostos do intelectualismo, do empirismo, ou antes, da Psicologia Clássica, mas tomando como base o vivido, o corpo como aquele que percebe, que está situado num mundo e que portanto ele tem um corpo que é fundante. É neste sentido que o seu projeto filosófico se fundamenta, em primeiro lugar, na tentativa de estabelecer um retorno ao vivido e a tarefa da compreensão de que a verdadeira filosofia é reaprender a ver o mundo. Por conseguinte, justifica-se uma investigação que irá pensar o corpo como obra de arte e como tal, inacabada e ao mesmo tempo, ele se dá através de seus desdobramentos na medida em que o sentido só é acessível por um contato direto. Do mesmo modo, partindo de uma compreensão merleau-pontiana de corpo como obra de arte, por fim, este trabalho assume também a tarefa de se indagar acerca da repercussão desta mesma afirmação na relação do saber filosófico consigo mesmo, logo, no modo da própria filosofia entender a sua história, estando, pois, a importância desta incursão no ensejo de explicitar o que, para Merleau Ponty, seria um corpo comparado a obra de arte como um nó de significações vivas e não a lei de um certo número de termos co-variantes.

"Amar demais": um estudo qualitativo sobre gênero e medicalização do amor

Esta dissertação apresenta um estudo qualitativo socioantropológico sobre o universo das "mulheres que amam demais anônimas" (MADA). Foram realizadas dezesseis entrevistas semiestruturadas com integrantes desses grupos de ajuda mútua sediados na cidade do Rio de Janeiro. O conjunto entrevistado é heterogêneo quanto à escolaridade e nível financeiro; a faixa etária concentra-se entre 40 e 50 anos e todas se declararam heterossexuais. O grupo orienta-se pela leitura recorrente do livro de Robin Norwood "Mulheres que amam demais" e suas reuniões são baseadas no compartilhamento das experiências afetivas. Há compromisso de anonimato e busca-se pela simetria entre as componentes. Tensões surgem em torno da possibilidade de hierarquização na gestão do grupo e no convívio via "amadrinhamento". Os discursos assinalam: a necessidade de controle do parceiro associada a baixo autocontrole (expresso por comportamentos considerados "compulsivos"); a dedicação intensa ao relacionamento ("viver em função do outro"); a valorização do enlace amoroso como fonte exclusiva de felicidade; e medo da solidão. O sentimento de "baixa autoestima" aparece como mecanismo explicativo desse tipo de vínculo. A interação conjugal é marcada por conflitos acerca da reciprocidade de atenção e cuidados, o que revela uma dinâmica de gênero particular ao mundo amoroso. A configuração do "amar demais" como "doença" no livro fundador do MADA estrutura-se pela analogia sistemática ao modelo de diagnóstico e recuperação do alcoolismo. As narrativas apresentaram forte adesão ao discurso 'psi' e médico. A caracterização do 'amor patológico' e a formulação de escalas para medi-lo, associadas à tentativa de empreendê-lo como categoria diagnóstica, configuram-se como importante movimento de medicalização do "amar demais".
