Argaric Sociology: Sex and Death

The detailed, rich and diverse Argaric funerary record offers an opportunity to explore social dimensions that usually remain elusive for prehistoric research, such us social rules on kinship rights and obligations, sexual tolerance and the role of funerary practices in preserving the economic and political organization. This paper addresses these topics through an analysis of the social meaning of Argaric double tombs by looking at body treatment and composition of grave goods assemblages according to gender and class affiliation. The Argaric seems to have been a conservative society, scarcely tolerant regarding homosexuality, and willing to celebrate ancestry associated to certain places as a means of asserting residence and property rights.

On a first-name basis: Englishization and naming in Flanders

Following and contributing to the ongoing shift from more structuralist, system-oriented to more pragmatic, socio-cultural oriented anglicism research, this paper verifies to what extent the global spread of English affects naming patterns in Flanders. To this end, a diachronic database of first names is constructed, containing the top 75 most popular boy and girl names from 2005 until 2014. In a first step, the etymological background of these names is documented and the evolution in popularity of the English names in the database is tracked. Results reveal no notable surge in the preference for English names. This paper complements these database-driven results with an experimental study, aiming to show how associations through referents are in this case more telling than associations through phonological form (here based on etymology). Focusing on the socio-cultural background of first names in general and of Anglo-American pop culture in particular, the second part of the study specifically reports on results from a survey where participants are asked to name the first three celebrities that leap to mind when hearing a certain first name (e.g. Lana, triggering the response Del Rey). Very clear associations are found between certain first names and specific celebrities from Anglo-American pop culture. Linking back to marketing research and the social turn in onomastics, we will discuss how these celebrities might function as referees, and how social stereotypes surrounding these referees are metonymically attached to their first names. Similar to the country-of-origin-effect in marketing, these metonymical links could very well be the reason why parents select specific “celebrity names”. Although further attitudinal research is needed, this paper supports the importance of including socio-cultural parameters when conducting onomastic research.

Comparing long-term placements for young children in care: Does type of placement really matter?

This paper presents findings from the third phase of a longitudinal study, entitled Care Pathways and Outcomes, which has been tracking the placements and measuring outcomes for a population of children (n = 374) who were under the age of five and in care in Northern Ireland on the 31st March 2000. It explores how a sub-sample of these children at age nine to 14 years old were getting on in the placements provided for them, in comparative terms across five placement types: adoption; foster care; kinship foster care (with relatives); on Residence Order; and living with birth parents. This specifically focused on the development of attachment and self-concept from the perspective of the children, and behavioural and emotional function, and parenting stress, from the perspective of parents and carers. Findings showed no significant placement effect from the perspective of children, and a statistically weak, but descriptively compelling, effect from the perspective of parents. The findings challenge the notion of adoption as the gold standard in long-term placements, specifically from the perspective of children in terms of their parent/carer attachments and self-concept, and highlight what appears to be the central importance of placement longevity for delivering positive longer-term outcomes for these children, irrespective of placement type.

Good year, bad year: changing strategies, changing networks? A two-year study on seed acquisition in northern Cameroon

Analysis of seed exchange networks at a single point in time may reify sporadic relations into apparently fixed and long-lasting ones. In northern Cameroon, where environment is not only strongly seasonal but also shows unpredictable interannual variation, farmers’ social networks are flexible from year to year. When adjusting their strategies, Tupuri farmers do not systematically solicit the same partners to acquire the desired propagules. Seed acquisitions documented during a single cropping season may thus not accurately reflect the underlying larger social network that can be mobilized at the local level. To test this hypothesis, we documented, at the outset of two cropping seasons (2010 and 2011), the relationships through which seeds were acquired by the members of 16 households in a Tupuri community. In 2011, farmers faced sudden failure of the rains and had to solicit distant relatives, highlighting their ability to quickly trigger specific social relations to acquire necessary seeding material. Observing the same set of individuals during two successive years and the seed sources they solicited in each year enabled us to discriminate repeated relations from sporadic ones. Although farmers did not acquire seeds from the same individuals from one year to the next, they relied on quite similar relational categories of people. However, the worse weather conditions during the second year led to (1) a shift from red sorghum seeds to pearl millet seeds, (2) a geographical extension of the network, and (3) an increased participation of women in seed acquisitions. In critical situations, women mobilized their own kin almost exclusively. We suggest that studying the seed acquisition network over a single year provides a misrepresentation of the underlying social network. Depending on the difficulties farmers face, they may occasionally call on relationships that transcend the local relationships used each year.

Identidade, memória e narrativas na dança de São Gonçalo do povoado Mussuca (SE)

This study deals with the participation of the dance of São Gonçalo of the Mussuca town/SE, in the process of construction of the ethnic identity among this social group. The Mussuca is a grouping recognized as afro-descendents, linked with black enslaved people in the valley of the Cotinguiba region. The collective memory functions as a drive of this linking with the past and if it makes to elaborate narratives on this descent. The objective of this study was to investigate the ways the rite went through to constitute itself as an element of ethnic representation. Internal and external agents had been identified who had participated in different contexts. By means of an ethnographic work we ve reached some aspects of the local structure social which demonstrated the contradictions through the social relations of the group. This process of ethnic autorecognition presents the kinship and the space question as definers of the social arrangements which establish its ethnic boundaries

A Study of pH Manipulation on Tumor Proliferation and the CTL Response

Adoptive Cell Transfer (ACT) Therapy is a cancer treatment that enhances and utilizes the body’s own immune system. However, this treatment has had limited success in clinical trials. We hypothesized that this is due to the immunosuppressive, acidic microenvironment of cancer tumors. We tested the effects of acidic, neutral, and basic environments in vitro on cytotoxic T lymphocyte (CTL) survival, activation, migration and killing ability and on cancer cell survival. We found that CTLs have most optimum survival, activation, and migration in a neutral environment, while the optimal extracellular conditions for EG-7 lymphoma are slightly acidic and B16-OVA melanoma survives best in physiological conditions. Future research should further study the killing ability of T cells in the three different environments and look to move to in vivo experiments.

Vivências dos cuidadores de idosos durante a internação hospitalar

O estudo objetivou conhecer as vivências do cuidador principal no cuidado do idoso no hospital. Realizou-se uma pesquisa descritiva exploratória de cunho qualitativo. Foi executada nas unidades de clínica médica, cirúrgica e serviço de pronto atendimento de um hospital universitário do sul do país, entre os meses de novembro e dezembro de 2013, através de um roteiro de entrevista, respondido por 11 cuidadores de idosos com doenças crônicas. As entrevistas foram transcritas e analisadas com a técnica de análise temática de Minayo. Nesta pesquisa, os cuidadores se caracterizam por ser, na sua maioria, do sexo feminino, casadas, com filhos, sem emprego remunerado e serem filhas do idoso hospitalizado. Os cuidadores participantes entendem a atividade de cuidar como um dever moral, resultado das relações pessoais e familiares. A partir do momento em que necessitam desempenhar tal papel, o assumem como uma exigência decorrente do fato de viverem em família. Os motivos que levaram o cuidador a desempenhar este papel relacionam-se com fatores inerentes ao idoso, como estado de saúde e grau de parentesco. Ao cuidador, fazem alusão ao dever/obrigação, gratidão/retribuição, grau de parentesco, gênero, proximidade afetiva, estado civil, situação atual de emprego e ausência de outra pessoa para realizar o cuidado. Durante o processo de hospitalização do idoso, o cuidador desenvolve ações, tem facilidades e dificuldades e utiliza estratégias que o auxiliam a cuidar. Ao vivenciar o cuidado ao idoso no hospital é influenciado a tornar-se cuidador, apresenta diversas experiências ao cuidar e precisa promover mudanças, em relação ao cuidado, com a internação do idoso. Ao implementar estratégias de cuidado durante a hospitalização do idoso, o familiar cuidador se organiza para cuidar e faz uso de uma rede de apoio para o cuidado. Constatou-se que o idoso e seu cuidador centralizam as necessidades e as decisões, que a rede de apoio informal é a principal provedora de auxílio durante a hospitalização do idoso e que a rede de apoio formal extrahospitalar é existente, porém não apresenta participação ativa no suporte do cuidador familiar. Por outro lado, a equipe de enfermagem responsável pelo cuidado intra-hospitalar foi uma participante ativa na totalidade dos relatos, provendo tanto o cuidado técnico especializado quanto a ajuda nas situações cotidianas emergentes, bem como suporte emocional aos cuidadores e idosos. Outro aspecto relevante destacado foi a falta de ajuda de alguns familiares no amparo aos cuidadores ou até mesmo ao idoso hospitalizado. Esse fato é considerado, pelos cuidadores, uma situação inaceitável, pois a família é vista como o sustentáculo em momentos de crise. As implicações deste estudo nas intervenções da enfermagem no cuidado ao doente e sua família estão relacionadas às discussões e reflexões, a serem realizadas pela equipe de saúde, acerca da inclusão do familiar no espaço hospitalar, pois a sua presença auxilia na manutenção da estabilidade física e emocional do idoso. Desta forma, a enfermagem poderá oferecer apoio ao familiar acompanhante para que se mantenha estável e possa formar uma parceria de cuidados, contribuindo na reabilitação do idoso.

How institutions shaped the last major evolutionary transition to large-scale human societies.

What drove the transition from small-scale human societies centred on kinship and personal exchange, to large-scale societies comprising cooperation and division of labour among untold numbers of unrelated individuals? We propose that the unique human capacity to negotiate institutional rules that coordinate social actions was a key driver of this transition. By creating institutions, humans have been able to move from the default ‘Hobbesian’ rules of the ‘game of life’, determined by physical/environmental constraints, into self-created rules of social organization where cooperation can be individually advantageous even in large groups of unrelated individuals. Examples include rules of food sharing in hunter–gatherers, rules for the usage of irrigation systems in agriculturalists, property rights and systems for sharing reputation between mediaeval traders. Successful institutions create rules of interaction that are self-enforcing, providing direct benefits both to individuals that follow them, and to individuals that sanction rule breakers. Forming institutions requires shared intentionality, language and other cognitive abilities largely absent in other primates. We explain how cooperative breeding likely selected for these abilities early in the Homo lineage. This allowed anatomically modern humans to create institutions that transformed the self-reliance of our primate ancestors into the division of labour of large-scale human social organization.

Social contact and trust: a study of a super diverse neighbourhood

This thesis presents an in-depth case study of a superdiverse neighbourhood in Glasgow where long-term white and ethnic minority communities reside alongside Roma migrants, asylum seekers and refugees, young professionals and other recent arrivals in traditional tenement housing. It focuses on the nature and extent of social contact and trust and on the role of context in shaping social relations. Employing the concepts of social milieu and intersectionality to identify social differences the research examines the relationships between five broad groupings of residents in the neighbourhood: Nostalgic Working Class, Scottish Asian, Liberal Homeowners, Kinship-sited Roma and Global Migrants. Ethnographic fieldwork was carried out in contexts within the neighbourhood, theorised as being potential sites for intergroup contact. Three types of interactions were examined: Group-based Interactions, Neighbour Interactions and Street Interactions. The data comprised documentary evidence, participant and direct observations, in-depth qualitative and walk-along interviews with residents and local organisations. Findings show that rather than individualising and isolating residents, superdiversity can stimulate community activism, yet there remains a preference for interaction within one’s own social milieu. The research has found that the concentration of poverty and material conditions has a more profound effect on social relations than historical diversity and the extent to which diversity is normalised within local discourses. Trust judgements in a superdiverse context may rely more on shared interests, moral outlook and assessments of the context rather than the extent of social contact. The quasi-private spaces of shared residential spaces and community activities can facilitate encounters with the potential to build trust, yet for this to occur cooperation through shared activities may not be sufficient. Interactions may need to move beyond co-presence and conviviality to increased understanding and empathy through dialogue. At an aggregate level, the extent to which superdiversity contributes to social contact and trust within the neighbourhood is strongly influenced by contextual factors and wider economic processes influencing housing tenure mix, private renting, property maintenance, residential churn and environmental conditions. Through examining different types of social contacts, the dynamics of trust as well as contextual influences, this thesis offers insights into the causal processes and factors that influence social relations at a local level.

Eighty years 'Owre the Sea': Robert Burns and the early United States of America, c. 1786-1866.

This thesis represents the first extensive critical study of the relationship between Robert Burns and the early United States of America. Spanning literature, history and memory studies, the following chapters take an interdisciplinary approach towards investigating the methods by which Burns and his works rose to prominence and came to be of cultural and literary significance in America. Theoretically, these converging disciplines intersect through a transnational, Atlantic Studies perspective that shifts emphasis from Burns as the 'national poet of Scotland' onto the various socio-cultural connections that facilitated the spread of his work and reputation. In addition to Scottish literary studies, the thesis contributes to the broader fields of Transatlantic, Transnational and American Studies. Previous studies have suggested that Burns's popularity in the early United States might be attributed to his kinship with 'national' American ideals of freedom, egalitarianism and individual liberty. While some of the evidence supports this claim, this thesis argues that it also wrongly assumes a spatiotemporal unity for the nineteenth-century American nation. It concludes by suggesting that future critical studies of the poet must heed the multifarious complexities of 'national' paradigms, pointing the way to further work on the reception and influence of Burns in other 'global' or, indeed, transnational contexts.

Studies on the protective immune response to Plasmodium chabaudi in mice

Inbred strains of C5731 and NIH nice infected with the A/S strain of Plasmodium chaubaudi usually developed high parasitaemias but infections were rarely fatal in immunocompetent mice and in most mice the parasites could be eradicated within 53 days or less. The immune response of C57B1 and NTH mice to infection with the A/S strain of P. chabaudi was studied. The principle method used in this study for investigating the immune response of the mice was to examine the immunity conferred on syngeneic mice, either X-irradiated or non-irradiated, by transferring to them lymphoid cells or serum from immune or semi-immune donors. The lymphoid cell populations examined were unfractionated spleen cells, nylon wool column enriched subpopulations of thymus-derived lymphocytes (T cells) and the so-called bursa-derived lymphocytes (B cells), bone marrow cells and phagocytic cells. In the course of these experiments observations were made on the effect of X-irradiation on the subsequent growth and multiplication of the parasite. In addition, an in vitro assay for antibody-dependent cell mediated cytotoxicity was used to investigate the activity of splenic K cells during malaria infection. K cells are lymphoid cells which may include lymphocytes of an undefined category, but possess receptors for the Fc portion of antibody on their surface and have the ability to non-specifically lyse target cells coated in antibodies. a) The adoptive transfer of immunity to P.chabaudi with immune spleen cells. Spleen cells from mice which had previously been infected with P.chabaudi were able to confer some immunity on syngeneic mice which had been irradiated with 600 or 800 rads. The protection was detected as a shortened patent parasitaemia in immune cell recipients compared to controls. The early experiments indicated the value of using irradiated recipients rather than non-irradiated recipients. In irradiated mice, a) smaller numbers of immune cells were required to promote detectable immunity than in non-irradiated mice, b) there was an amplification of the difference in the duration of primary parasitaemias in recipients of immune cells and normal cells compared to non-irradiated mice and c) as the irradiated host is immunodepressed, the protective effect of donor cells can be examined with a reduced contribution by the hosts own immune system. An initial non-specific resistance to P.chabaudi infection was observed in irradiated mice, although the infection in most of these mice was subsequently more severe than in non-irradiated mice. The non-specific resistance could be reduced or abolished by injecting lymphoid cells into mice shortly after irradiation or by infecting irradiated mice more than 15 days after irradiation. Other workers suggest that following irradiation, the reticulo-endothelial system is stimulated at the time that the non-specific resistance to P.chabaudi was observed. b) the adoptive transfer of immunity in syngeneic mice with enriched subpopulations of splenic immune T cells, B. cells, bone marrow cells and phagocytes. Immunity to P.chabaudi could be adoptively transferred with enriched spleen subpopulations of immune T cells or immune B cells in mice which had been irradiated 600 or 300 rads. The protective effects of unfractionated immune cells was, however, usually better than that of either immune T or F cell subpopulations. In most experiments enriched immune T cell recipients were more likely to suffer relapsing patent parasitaemias than either enriched immune B cell recipients or unfractionated immune cell recipients. In one experiment a comparison was made of the course of P.chabaudi infection in mice which had been irradiated with either 600 rads or 300 rads and which received injections of different immune cells. A dose of 600 rads permits the immune system of mice to recover from the effects of irradiation, but a dose of 800 rads is lethal to mice unless lymphoid cells are injected after irradiation. It was found that in recipients of enriched immune T or B cells, which had been irradiated with 600 rads, the parasitaemia became subpatent before their equivalents irradiated with 800 rads, but that there was little difference in parasitaemias between recipients of unfractionated immune cells given 600 or 800 rads. Experiments in which enriched immune T cells and B cells were recombined and injected into syngeneic mice gave inconclusive results as to whether the immune subpopulations acted synergistically. Similar experiments in which immune subpopulations of lymphoid cells were recombined with normal subpopulations of lymphoid cells demonstrated that the latter cells did not enhance the protective effect of the former cells. Bone marrow cells from immune mice were able to confer some protection on syngeneic recipients, but were not as protective as enriched immune T cells or B cells. The results obtained in adoptive transfer experiments using phagocytic cells from the spleen of immune mice depended on the length of time spleen cells were incubated in petri-dishes at 37° C before harvesting the phagocytes. Using C57B1 mice, phagocytes harvested after 15 hours incubation were as protective as unfractionated immune cells in a cell transfer experiment, but phagocytes harvested after 16 hours incubation were not protective. Examination of NIH phagocytic cells after 2.5 hours incubation at 37°C, which were as protective as unfractionated immune spleen cells in a cell transfer experiment, demonstrated that the petri-dish adherent cells may have contained B lymphocytes. c) The passive transfer of immunity with serum from P.chabaudi infected mice. The passive transfer of serum from C57B1 mice which had been previously infected with P.chabaudi to normal or irradiated syngeneic mice demonstrated that the serum recipients were initially protected from infection. Irradiated mice, however, were delayed longer in the onset of parasitaemia compared to non-irradiated mice. Using NIH mice, sera were collected from unfractionated immune spleen cell recipients, enriched immune T cell recipients and normal spleen recipients on the 11th day of a P.chabaudi infection, just after peak parasitaemia, and also on the 14th day of infection. On day 14, all immune cells recipients and most of the enriched immune T cell recipients had become subpatent but all normal cell recipients still had patent infections. Sera collected from the different spleen cell recipients on the 11th day of infection and passively transferred to irradiated mice demonstrated little protection. Sera collected on the 14th day of infect ion, however, reflected the immune status of the donors in their protective properties in mice infected with P.chabaudi. The serum from unfractionated immune cell recipients was the most protective of the 3 sera when compared to normal NIH serum and the serum from enriched immune T cell recipients was slightly protective, but the serum from normal cell recipients produced an enhanced infection in mice infected with P.chabaudi. d) Antibody-dependent cell-mediated cytotoxicity of spleen cells in P.chabaudi infected mice. In a preliminary investigation of K cell activity in the spleens of P.chabaudi infected mice, it was found that there was an increased activity of K cells collected at around peak parasitaemia compared to the activity of K cells in non-infected mice, and that this increased activity could also be found in mice which had recently become subpatent. As the target cell for antibody-dependent cell-mediated cytotoxicity employed was the thick red blood cell, it is not known whether the K cell is involved in the killing of P.chabaudi parasites. These results suggest that both T cells and B cells and antibody may be important in the immune response to P.chabaudi in mice. Primed T cells may act as helper cells in the production of malarial antibodies, but, as enriched primed T cells could confer protection on immunodepressed mice, it is possible that a cell-mediated mechanism of immunity may also exist.
