Social Care and Obesity: A discussion paper

The number of obese people in England has been rising steadily for the best part of 20 years. Today one in four adults are obese, according to the Health Survey for England, compared to 15 per cent in 1993. Obesity is associated with a range of health problems including type 2 diabetes, cardiovascular disease and cancer. The resulting NHS costs attributable to overweight and obesity are projected to reach £9.7 billion by 2050 [1], with wider costs to society estimated to reach £49.9 billion per year. These factors combine to make the prevention of obesity a major public health challenge. This discussion paper considers the impact that obesity has on social care and the challenges facing social care now and in the future.

Social structure varies with elevation in an Alpine ant.

Insect societies vary greatly in social organization, yet the relative roles of ecological and genetic factors in driving this variation remain poorly understood. Identifying how social structure varies along environmental gradients can provide insights into the ecological conditions favouring alternative social organizations. Here, we investigate how queen number variation is distributed along elevation gradients within a socially polymorphic ant, the Alpine silver ant Formica selysi. We sampled low- and high-elevation populations in multiple Alpine valleys. We show that populations belonging to different drainage basins are genetically differentiated. In contrast, there is little genetic divergence between low- and high-elevation populations within the same drainage basin. Thus, elevation gradients in each of the drainage basins represent independent contrasts. Whatever the elevation, all well-sampled populations are socially polymorphic, containing both monogynous (= one queen) and polygynous (= multiple queen) colonies. However, the proportion of monogynous colonies per population increases at higher elevation, while the effective number of queens in polygynous colonies decreases, and this pattern is replicated in each drainage basin. The increased prevalence of colonies with a single queen at high elevation is correlated with summer and winter average temperature, but not with precipitation. The colder, unpredictable and patchy environment encountered at higher elevations may favour larger queens with the ability to disperse and establish incipient monogynous colonies independently, while the stable and continuous habitat in the lowlands may favour large, fast-growing polygynous colonies. By highlighting differences in the environmental conditions favouring monogynous or polygynous colonies, this study sheds light on the ecological factors influencing the distribution and maintenance of social polymorphism.

Association between social relationships and survival of Swiss octogenarians. A five-year prospective, population-based study.

BACKGROUND AND AIMS: Data from the literature reveal the contrasting influences of family members and friends on the survival of old adults. On one hand, numerous studies have reported a positive association between social relationships and survival. On the other, ties with children may be associated with an increased risk of disability, whereas ties with friends or other relatives tend to improve survival. A five-year prospective, population-based study of 295 Swiss octogenarians tested the hypothesis that having a spouse, siblings or close friends, and regular contacts with relatives or friends are associated with longer survival, even at a very old age. METHODS: Data were collected through individual interviews, and a Cox regression model was applied to assess the effects of kinship and friendship networks on survival, after adjusting for socio-demographic and health-related variables. RESULTS: Our analyses indicate that the presence of a spouse in the household is not significantly related to survival, whereas the presence of siblings at baseline improves the oldest old's chances of surviving five years later. Moreover, the existence of close friends is a central component in the patterns of social relationships of oldest adults, and one which is significantly associated with survival. Overall, the protective effect of social relationships on survival is more related to the quality of those relationships (close friends) than to the frequency of relationships (regular contacts). CONCLUSIONS: We hypothesize that the existence of siblings or close friends may beneficially affect survival, due to the potential influence on the attitudes of octogenarians regarding health practices and adaptive strategies.

Social evolution and defences against pathogens in ants

Pathogens represent a threat to all organisms, which generates a coevolutionary arms race. Social insects provide an interesting system to study host-pathogen interactions, because their defences depend on both the individual and collective responses, and involve genetic, physiological, behavioral and organizational mechanisms. In this thesis, I studied the evolutionary ecology of the resistance of ant queens and workers to natural fungal pathogens. Mechanisms that increase within-colony genetic diversity, like polyandry and polygyny, decrease relatedness among colony mates, which reduces the strength of selection for the evolution and maintenance of altruistic behavior. A leading hypothesis posits that intracolonial genetic diversity is adaptive because it reduces the risk of pathogen transmission. In chapter 1, I examine individual resistance in ant workers of Formica selysi, a species that shows natural variation in colony queen number. I discuss how this variation might be beneficial to resist natural fungal pathogens in groups. Overall my results indicate that there is genetic variation for fungal resistance in workers, a requirement for the 'genetic diversity for pathogen resistance' hypothesis. However I was not able to detect direct evidence that group diversity improves the survival of focal ants or reduces pathogen transmission. Thus, although the coexistence of multiple queens increases the within-colony variance in worker resistance, it remains unclear whether it protects ant colonies from pathogens and whether it is comparable to polyandry in other social insects. Traditionally, it was thought that the immune system of invertebrates lacked memory and specificity. In chapter 2, I investigate individual immunity in ant queens and show that they may be able to adjust their pathogen defences in response to their current environment by means of immune priming, which bears similarities with the adaptive immunity of vertebrates. However, my results indicate that the expression of immune priming in ant queens may be influenced by factors like mating status, mating conditions or host species. In addition, I showed that mating increases pathogen resistance in çhe two ant species that I studied (F. selysi and Lasius niger). This raises the question of how ant queens invest heavily in both maintenance and reproduction, which I discuss in the context of the evolution of social organization. In chapter 3,1 investigate if transgenerational priming against a fungal pathogen protects the queen progeny. I failed to detect this effect, and discuss why the detection of transgenerational immune priming in ants is a difficult task. Overall, this thesis illustrates some of the individual and collective mechanisms that likely played a role in allowing ants to become one of the most diverse and ecologically successful groups of organisms. -- Les pathogènes représentent une menace pour tous les organismes, ce qui a engendré l'évolution d'une course aux armements. Les insectes sociaux sont un système intéressant permettant d'étudier les interactions hôtes-pathogènes, car leurs défenses dépendent de réponses aussi bien individuelles que collectives, et impliquent des mécanismes génétiques, physiologiques, comportementaux et organisationnels. Dans cette thèse, j'ai étudié l'écologie évolutive de la résistance des reines et des ouvrières de fourmis exposées à des champignons pathogènes. Les facteurs augmentant la diversité génétique à l'intérieur de la colonie, comme la polyandrie et la polygynie, diminuent la parenté, ce qui réduit la pression de sélection pour l'évolution et la maintenance des comportements altruistes. Une hypothèse dominante stipule que la diversité génétique à l'intérieur de la colonie est adaptative car elle réduit le risque de transmission des pathogènes. Dans le chapitre 1, nous examinons la résistance individuelle à des pathogènes fongiques chez les ouvrières de Formica selysi, une espèce présentant une variation naturelle dans le nombre de reines par colonie. Nous discutons aussi de la possibilité que ces variations individuelles augmentent la capacité du groupe à résister à des champignons pathogènes. Dans l'ensemble, nos résultats indiquent une variation génétique dans la résistance aux champignons chez les ouvrières, un prérequis à l'hypothèse que la diversité génétique du groupe augmente la résistance aux pathogènes. Cependant, nous n'avons pas pu détecter une preuve directe que la diversité du groupe augmente la survie de fourmis focales ou réduise la transmission des pathogènes. Ainsi, bien que la coexistence de plusieurs reines augmente la variance dans la résistance des ouvrières à l'intérieur de la colonie, la question de savoir si cela protège les colonies de fourmis contre les pathogènes et si cela est comparable à la polyandrie chez d'autres insectes sociaux reste ouverte. Traditionnellement, il était admis que le système immunitaire des invertébrés ne possédait pas de mémoire et était non-spécifique. Dans le chapitre 2, nous avons étudié l'immunité individuelle chez des reines de fourmis. Nous avons montré que les reines pourraient être capables d'ajuster leurs défenses contre les pathogènes en réponse à leur environnement, grâce à une pré-activation du système immunitaire (« immune priming ») ressemblant à l'immunité adaptative des vertébrés. Cependant, nos résultats indiquent que cette pré-activation du système immunitaire chez les reines dépend du fait d'être accouplée ou non, des conditions d'accouplement, ou de l'espèce. De plus, nous avons montré que l'accouplement augmente la résistance aux pathogènes chez les deux espèces que nous avons étudié (F. selysi et Lasius niger). Ceci pose la question de la capacité des reines à investir fortement aussi bien dans la maintenance que dans la reproduction, ce que nous discutons dans le contexte de l'évolution de l'organisation sociale. Dans le chapitre 3, nous étudions si la pré-activation trans-générationelle du système immunitaire [« trans-generational immune priming ») protège la progéniture de la reine contre un champignon pathogène. Nous n'avons par réussi à détecter cet effet, et discutons des raisons pour lesquelles la détection de la pré-activation trans-générationelle du système immunitaire chez les fourmis est une tâche difficile. Dans l'ensemble, cette thèse illustre quelques-uns des mécanismes individuels et collectifs qui ont probablement contribué à la diversité et à l'important succès écologique des fourmis.

Social inequalities and mortality in Europe-results from a large multi-national cohort

BACKGROUND Socio-economic inequalities in mortality are observed at the country level in both North America and Europe. The purpose of this work is to investigate the contribution of specific risk factors to social inequalities in cause-specific mortality using a large multi-country cohort of Europeans. METHODS A total of 3,456,689 person/years follow-up of the European Prospective Investigation into Cancer and Nutrition (EPIC) was analysed. Educational level of subjects coming from 9 European countries was recorded as proxy for socio-economic status (SES). Cox proportional hazard model's with a step-wise inclusion of explanatory variables were used to explore the association between SES and mortality; a Relative Index of Inequality (RII) was calculated as measure of relative inequality. RESULTS Total mortality among men with the highest education level is reduced by 43% compared to men with the lowest (HR 0.57, 95% C.I. 0.52-0.61); among women by 29% (HR 0.71, 95% C.I. 0.64-0.78). The risk reduction was attenuated by 7% in men and 3% in women by the introduction of smoking and to a lesser extent (2% in men and 3% in women) by introducing body mass index and additional explanatory variables (alcohol consumption, leisure physical activity, fruit and vegetable intake) (3% in men and 5% in women). Social inequalities were highly statistically significant for all causes of death examined in men. In women, social inequalities were less strong, but statistically significant for all causes of death except for cancer-related mortality and injuries. DISCUSSION In this European study, substantial social inequalities in mortality among European men and women which cannot be fully explained away by accounting for known common risk factors for chronic diseases are reported.

State-Society Relationships, Social Trust and the Development of Labour Market Policies in Italy and Sweden

The first decade of the twenty-first century may be remembered for the rebirth of consensus on labour market policy. After three decades of bitter political and ideological controversy between a neo-liberal and a traditional social democratic approach, a new model, often labelled flexicurity, has emerged. This model is promoted by numerous political organisations since it promises to put an end to the old trade-off between equality and efficiency. Several countries are embracing the flexicurity model as a blueprint for labour market reform, but others, mostly belonging to the 'Mediterranean Rim', are clearly lagging behind. Why is it so difficult for these countries to implement the flexicurity model? This paper argues that the application of a flexicurity strategy in these countries is complicated by the lack of social trust between social partners and the state as well as political economy traditions that highlight the role of labour market regulation as a source of social protection.

The generation and re-generation of social capital and enterprises in multi-stakeholders social cooperative enterprises: a system dynamic approach

Theories on social capital and on social entrepreneurship have mainly highlighted the attitude of social capital to generate enterprises and to foster good relations between third sector organizations and the public sector. This paper considers the social capital in a specific third sector enterprise; here, multi-stakeholder social cooperatives are seen, at the same time, as social capital results, creators and incubators. In the particular enterprises that identify themselves as community social enterprises, social capital, both as organizational and relational capital, is fundamental: SCEs arise from but also produce and disseminate social capital. This paper aims to improve the building of relational social capital and the refining of helpful relations drawn from other arenas, where they were created and from where they are sometimes transferred to other realities, where their role is carried on further (often working in non-profit, horizontally and vertically arranged groups, where they share resources and relations). To represent this perspective, we use a qualitative system dynamic approach in which social capital is measured using proxies. Cooperation of volunteers, customers, community leaders and third sector local organizations is fundamental to establish trust relations between public local authorities and cooperatives. These relations help the latter to maintain long-term contracts with local authorities as providers of social services and enable them to add innovation to their services, by developing experiences and management models and maintaining an interchange with civil servants regarding these matters. The long-term relations and the organizational relations linking SCEs and public organizations help to create and to renovate social capital. Thus, multi-stakeholder cooperatives originated via social capital developed in third sector organizations produce new social capital within the cooperatives themselves and between different cooperatives (entrepreneurial components of the third sector) and the public sector. In their entrepreneurial life, cooperatives have to contrast the "working drift," as a result of which only workers remain as members of the cooperative, while other stakeholders leave the organization. Those who are not workers in the cooperative are (stake)holders with "weak ties," who are nevertheless fundamental in making a worker's cooperative an authentic social multi-stakeholders cooperative. To maintain multi-stakeholder governance and the relations with third sector and civil society, social cooperatives have to reinforce participation and dialogue with civil society through ongoing efforts to include people that provide social proposals. We try to represent these processes in a system dynamic model applied to local cooperatives, measuring the social capital created by the social cooperative through proxies, such as number of volunteers and strong cooperation with public institutions. Using a reverse-engineering approach, we can individuate the determinants of the creation of social capital and thereby give support to governance that creates social capital.

Social media and political change: The case of the 2011 revolutions in Tunisia and Egypt

Throughout the past decade, social media have come on the scene of various popular revolts. Their role as tools of information and coordination of social movements, from the Iranian Green Movement in 2009 to the Arab uprisings in 2011, has been widely debated. In most cases, online activism through blogs, Facebook, Twitter or other forms of social media has allowed citizens to be part of a social networking exercise and to engage in a public sphere that would have otherwise been unreachable to them due to severe repression. In Tunisia and Egypt, social media helped protests start and expand thanks to their ability to coordinate and disseminate information quickly. The new information and communication tools were an influential factor in accelerating the revolutionary processes across the Arab world, albeit they cannot be seen as neither the spur nor the drivers of any revolution.

Social capital and the equilibrium number of entrepreneurs

Social capital is viewed either as a proprietary asset that serves private interests, including those of entrepreneurs, or as a collective asset that supports trust-based transactions saving on transaction costs both in markets and within the boundaries of firms, and benefiting society as a whole. This paper explains the relative specialization between entrepreneurs and market-governed exchanges as a result of the interaction between social capital that lowers transaction costs, and the scale economies of ability in managerial jobs (Lucas 1978). The main hypothesis formulated in the paper is that higher social capital will benefit the hierarchy relatively more than the market as a governance mechanism, and therefore in economies with higher social capital, the equilibrium number of entrepreneurs will be lower and their average span of control larger than in economies with lower social capital. The empirical evidence, with data from the Spanish Autonomous Communities, is consistent with this prediction.

Influencia social y uso del preservativo en la prevención de la transmisión heterosexual del VIH = Social influence and condom use for VIH heterosexual transmission prevention

Se revisan diferentes formas en que la influencia social puede incidir sobre los comportamientosheterosexuales de prevención de la transmisión del VIH de los jóvenes y se presentanlos resultados de algunos trabajos de las autoras, así como de otros investigadores, en que seanalizan dichas relaciones. Se concluye resaltando: 1) la utilidad clínica de la evaluación de lasexpectativas de autoeficacia para poder intervenir específicamente en aquellas áreas en que losjóvenes se perciban con menores capacidades para ser preventivos, 2) la relación observadaentre el uso de preservativo autoinformado y la creencia en su aceptación por parte de los referentessociales más cercanos y 3) la conveniencia de que los jóvenes posean suficientes habilidadesde comunicación que les permitan negociar con éxito el uso del preservativo y les ayudena compensar posibles influencias sociales en contra de su empleo
