Robots and cyborgs: to be or to have a body?

Starting with service robotics and industrial robotics, this paper aims to suggest philosophical reflections about the relationship between body and machine, between man and technology in our contemporary world. From the massive use of the cell phone to the robots which apparently “feel” and show emotions like humans do. From the wearable exoskeleton to the prototype reproducing the artificial sense of touch, technological progress explodes to the extent of embodying itself in our nakedness. Robotics, indeed, is inspired by biology in order to develop a new kind of technology affecting human life. This is a bio-robotic approach, which is fulfilled in the figure of the cyborg and consequently in the loss of human nature. Today, humans have reached the possibility to modify and create their own body following their personal desires. But what is the limit of this achievement? For this reason, we all must question ourselves whether we have or whether we are a body

'A habitual disposition to the good': on reason, virtue and realism

Amidst the crisis of instrumental reason, a number of contemporary political philosophers including Jürgen Habermas have sought to rescue the project of a reasonable humanism from the twin threats of religious fundamentalism and secular naturalism. In his recent work, Habermas defends a post-metaphysical politics that aims to protect rationality against encroachment while also accommodating religious faith within the public sphere. This paper contends that Habermas’ post-metaphysical project fails to provide a robust alternative either to the double challenge of secular naturalism and religious fundamentalism or to the ruthless instrumentalism that underpins capitalism. By contrast with Habermas and also with the ‘new realism’ of contemporary political philosophers such as Raymond Geuss or Bernard Williams, realism in the tradition of Plato and Aristotle can defend reason against instrumental rationality and blind belief by integrating it with habit, feeling and even faith. Such metaphysical–political realism can help develop a politics of virtue that goes beyond communitarian thinking by emphasising plural modes of association (not merely ‘community’), substantive ties of sympathy and the importance of pursuing goodness and mutual flourishing

A snapshot of the prevalence of physical activity amongst older, community dwelling people in Victoria, Australia: patterns across the 'young-old' and 'old-old'

BACKGROUND: Physical activity has a range of health benefits for older people. The aim of this study was to determine physical activity prevalence and attitudes amongst respondents to a trial screening survey. METHODS: A cross-sectional survey was conducted. Subjects were community dwelling older people aged ≥ 65 years, recruited via general practices in Victoria, Australia. Participants completed a mailed screening tool containing the Geriatric Depression Scale, the Active Australia survey and the Physical Activity Readiness Questionnaire. RESULTS: Of 330 participants, 20% were ≥ 80 years. Activity levels were similar to those reported in population studies. The proportion of participants reporting physical activity was greatest for the walking category, but decreased across categories of physical activity intensity. The oldest-old were represented at all physical activity intensity levels. Over half reported exercising at levels that, according to national criteria are, 'sufficient to attain health benefit'. A greater proportion of participants aged 85 years and older were unaware of key physical activity messages, compared to participants aged less than 85 years. CONCLUSION: Most population surveys do not provide details of older people across age categories. This survey provided information on the physical activity of people up to 91 years old. Physical activity promotion strategies should be tailored according to the individual's needs. A better understanding of the determinants of physical activity behaviour amongst older sub-groups is needed to tailor and target physical activity promotion strategies and programs to maximise physical activity related health outcomes for older people

Introduction : narcissism, melancholia and the subject of community.

Sigmund Freud’s twin papers, ‘On Narcissism: An Introduction’ (1914) and ‘Mourning and Melancholia’ (1917 [1915]), take as their formative concern the difficulty of setting apart the ‘inner’ and the ‘outer’ worlds, and of preserving a stable image of a boundaried self. Whilst it is true that the term narcissism especially has come to be deployed in ways that seem foreign to the complexities of Freud’s 1914 paper (by its reduction to a personality disorder or its use as a broad-brush cultural diagnosis), we suggest in this introductory chapter that neither narcissism nor melancholia can be thought about today without expressing some debt to Freudian metapsychology. However, whereas Freud was most evidently concerned to describe the structure of ego-formation, subsequent commentators have preferred to emphasize the cultural and normative dimensions of these terms. Accordingly, we consider the respective discursive histories of narcissism and melancholia and find that although they have been put to work in very different ways they remain grounded by a shared concern with mechanisms of relation and identification. Indeed, this shared concern is the basis upon which they’ve been most productively reanimated in recent years: the rise of melancholia as a critical aid to the study of cultural displacement and dispossession, and the determined redemption of narcissism from its pejorative characterization as fundamentally anti-social. We argue that what is most noteworthy in this post-Freudian literature is the increasing relevance of metapsychology to social and political theory. The language of psychoanalysis, extrapolated from the clinic, permits a detailed examination of the boundaries which construct and challenge the terms of social solidarity. Specifically, this takes place though careful reading of the complex practices of (dis)identification at the heart of ego-formation (at both individual and group levels), and the associated mechanisms of defence, for example: introjection, incorporation, projective-identification, and splitting. By recognising the complexity of how communities get made, and connecting this with recent literature on counter publics and the commons, we demonstrate that Freud’s frameworks of narcissism and melancholia remain essential for any contemporary understanding of political association

(Re) Locating community in relationships: questions for public policy

This is the author accepted manuscript. The final version is available from SAGE Publications via the DOI in this record.This paper argues that we should think of community as being about social relationships rather than a ‘thing’ that is ‘lost’, ‘found’ or ‘made’. The paper draws on the philosophy of Roberto Esposito and the sociology of David Studdert to highlight the overlaps in their approaches to community. Both argue that community is ontological, as unavoidably ‘with us’. The paper then draws upon two empirical examples to argue that this approach could enable a different kind of public policy in relation to community. Policy would focus on existing relationships as the starting point for any efforts to effect social change. The implications for contemporary debates about localism are explored at the end of the paper.I am very grateful to David Studdert and Valerie Walkerdine for inviting me to the workshop on community and localism held at Cardiff University in April 2014 that stimulated this special issue of Sociological Review. I am also very grateful to the Leverhulme Trust for the research funding and to Nick Coke, Tessy Britton and Laura Billings for their invaluable contributions to the arguments made. The comments from three referees, the editors and Patrick Devine-Wright were extremely helpful in improving the paper

31st Annual Meeting and Associated Programs of the Society for Immunotherapy of Cancer (SITC 2016) : part two

Background The immunological escape of tumors represents one of the main ob- stacles to the treatment of malignancies. The blockade of PD-1 or CTLA-4 receptors represented a milestone in the history of immunotherapy. However, immune checkpoint inhibitors seem to be effective in specific cohorts of patients. It has been proposed that their efficacy relies on the presence of an immunological response. Thus, we hypothesized that disruption of the PD-L1/PD-1 axis would synergize with our oncolytic vaccine platform PeptiCRAd. Methods We used murine B16OVA in vivo tumor models and flow cytometry analysis to investigate the immunological background. Results First, we found that high-burden B16OVA tumors were refractory to combination immunotherapy. However, with a more aggressive schedule, tumors with a lower burden were more susceptible to the combination of PeptiCRAd and PD-L1 blockade. The therapy signifi- cantly increased the median survival of mice (Fig. 7). Interestingly, the reduced growth of contralaterally injected B16F10 cells sug- gested the presence of a long lasting immunological memory also against non-targeted antigens. Concerning the functional state of tumor infiltrating lymphocytes (TILs), we found that all the immune therapies would enhance the percentage of activated (PD-1pos TIM- 3neg) T lymphocytes and reduce the amount of exhausted (PD-1pos TIM-3pos) cells compared to placebo. As expected, we found that PeptiCRAd monotherapy could increase the number of antigen spe- cific CD8+ T cells compared to other treatments. However, only the combination with PD-L1 blockade could significantly increase the ra- tio between activated and exhausted pentamer positive cells (p= 0.0058), suggesting that by disrupting the PD-1/PD-L1 axis we could decrease the amount of dysfunctional antigen specific T cells. We ob- served that the anatomical location deeply influenced the state of CD4+ and CD8+ T lymphocytes. In fact, TIM-3 expression was in- creased by 2 fold on TILs compared to splenic and lymphoid T cells. In the CD8+ compartment, the expression of PD-1 on the surface seemed to be restricted to the tumor micro-environment, while CD4 + T cells had a high expression of PD-1 also in lymphoid organs. Interestingly, we found that the levels of PD-1 were significantly higher on CD8+ T cells than on CD4+ T cells into the tumor micro- environment (p < 0.0001). Conclusions In conclusion, we demonstrated that the efficacy of immune check- point inhibitors might be strongly enhanced by their combination with cancer vaccines. PeptiCRAd was able to increase the number of antigen-specific T cells and PD-L1 blockade prevented their exhaus- tion, resulting in long-lasting immunological memory and increased median survival
