The New Instantaneity: How Social Media are Helping us Privilege the (Politically) Correct over the True

The recent sacking of the eminent scientist Tim Hunt from one of the UK’s leading research institutions is only the latest in a series of cases where public individuals have been derided for comments made in jest on social media, with serious consequences for their professional and personal lives. This article discusses the case of Tim Hunt as an example of the extent to which the privileging of the correct over the true which has long pervaded media discourse is taken to the extreme by the instant-response culture of social media. It points to the emergence of a new form of instantaneity enabled by these networked forms of communication that serves to reinforce systemic inaction rather than the change widely associated with these technologies. It draws on philosophy and Critical Theory as useful conceptual frameworks for highlighting the ways in which Twitter & co. increasingly call us to action but crowd out thought, thereby passing over opportunities for real social change

Parenteral nutrition in the intensive care unit: cautious use improves outcome.

Critical illness is characterised by nutritional and metabolic disorders, resulting in increased muscle catabolism, fat-free mass loss, and hyperglycaemia. The objective of the nutritional support is to limit fat-free mass loss, which has negative consequences on clinical outcome and recovery. Early enteral nutrition is recommended by current guidelines as the first choice feeding route in ICU patients. However, enteral nutrition alone is frequently associated with insufficient coverage of the energy requirements, and subsequently energy deficit is correlated to worsened clinical outcome. Controlled trials have demonstrated that, in case of failure or contraindications to full enteral nutrition, parenteral nutrition administration on top of insufficient enteral nutrition within the first four days after admission could improve the clinical outcome, and may attenuate fat-free mass loss. Parenteral nutrition is cautious if all-in-one solutions are used, glycaemia controlled, and overnutrition avoided. Conversely, the systematic use of parenteral nutrition in the ICU patients without clear indication is not recommended during the first 48 hours. Specific methods, such as thigh ultra-sound imaging, 3rd lumbar vertebra-targeted computerised tomography and bioimpedance electrical analysis, may be helpful in the future to monitor fat-free mass during the ICU stay. Clinical studies are warranted to demonstrate whether an optimal nutritional management during the ICU stay promotes muscle mass and function, the recovery after critical illness and reduces the overall costs

Relatively Complete Counterexamples for Higher-Order Programs

In this paper, we study the problem of generating inputs to a higher-order program causing it to error. We first study the problem in the setting of PCF, a typed, core functional language and contribute the first relatively complete method for constructing counterexamples for PCF programs. The method is relatively complete in the sense of Hoare logic; completeness is reduced to the completeness of a first-order solver over the base types of PCF. In practice, this means an SMT solver can be used for the effective, automated generation of higher-order counterexamples for a large class of programs. We achieve this result by employing a novel form of symbolic execution for higher-order programs. The remarkable aspect of this symbolic execution is that even though symbolic higher-order inputs and values are considered, the path condition remains a first-order formula. Our handling of symbolic function application enables the reconstruction of higher-order counterexamples from this first-order formula. After establishing our main theoretical results, we sketch how to apply the approach to untyped, higher-order, stateful languages with first-class contracts and show how counterexample generation can be used to detect contract violations in this setting. To validate our approach, we implement a tool generating counterexamples for erroneous modules written in Racket.Comment: In Proceedings of the 36th annual ACM SIGPLAN conference on Programming Language Design and Implementation, Portland, Oregon, June 201

Kinds of well-being: A conceptual framework that provides direction for caring

This article offers a conceptual framework by which different kinds and levels of well-being can be named, and as such, provides a foundation for a resource-oriented approach in situations of illness and vulnerability (rather than a deficit-oriented approach). Building on a previous paper that articulated the philosophical foundations of an existential theory of well-being (“Dwelling-mobility”), we show here how the theory can be further developed towards practice-relevant concerns. We introduce 18 kinds of well-being that are intertwined and inter-related, and consider how each emphasis can lead to the formulation of resources that have the potential to give rise to well-being as a felt experience. By focusing on a much wider range of well-being possibilities, practitioners may find new directions for care that are not just literal but also at an existential level

Social media, protest cultures and political subjectivities of the Arab spring

This article draws on phenomenological perspectives to present a case against resisting the objectification of cultures of protest and dissent. The generative, self-organizing properties of protest cultures, especially as mobilized through social media, are frequently argued to elude both authoritarian political structures and academic discourse, leading to new political subjectivities or ‘imaginaries’. Stemming from a normative commitment not to over-determine such nascent subjectivities, this view has taken on a heightened resonance in relation to the recent popular uprisings in the Middle East and North Africa. The article argues that this view is based on an invalid assumption that authentic political subjectivities and cultures naturally emerge from an absence of constraint, whether political, journalistic or academic. The valorisation of amorphousness in protest cultures and social media enables affective and political projection, but overlooks politics in its institutional, professional and procedural forms

Achieving equity through 'gender autonomy': the challenges for VET policy and practice

This paper is based on research carried out in an EU Fifth Framework project on 'Gender and Qualification'. The research partners from five European countries investigated the impact of gender segregation in European labour markets on vocational education and training, with particular regard to competences and qualifications. The research explored the part played by gender in the vocational education and training experiences of (i) young adults entering specific occupations in child care, electrical engineering and food preparation/service (ii) adults changing occupations

"Engaging with birth stories in pregnancy: a hermeneutic phenomenological study of women's experiences across two generations"

BACKGROUND: The birth story has been widely understood as a crucial source of knowledge about childbirth. What has not been reported is the effect that birth stories may have on primigravid women's understandings of birth. Findings are presented from a qualitative study exploring how two generations of women came to understand birth in the milieu of other's stories. The prior assumption was that birth stories must surely have a positive or negative influence on listeners, steering them towards either medical or midwifery-led models of care. METHODS: A Heideggerian hermeneutic phenomenological approach was used. Twenty UK participants were purposively selected and interviewed. Findings from the initial sample of 10 women who were pregnant in 2012 indicated that virtual media was a primary source of birth stories. This led to recruitment of a second sample of 10 women who gave birth in the 1970s-1980s, to determine whether they were more able to translate information into knowledge via stories told through personal contact and not through virtual technologies RESULTS: Findings revealed the experience of 'being-in-the-world' of birth and of stories in that world. From a Heideggerian perspective, the birth story was constructed through 'idle talk' (the taken for granted assumptions of things, which come into being through language). Both oral stories and those told through technology were described as the 'modern birth story'. The first theme 'Stories are difficult like that', examines the birth story as problematic and considers how stories shape meaning. The second 'It's a generational thing', considers how women from two generations came to understand what their experience might be. The third 'Birth in the twilight of certainty,' examines women's experience of Being in a system of birth as constructed, portrayed and sustained in the stories being shared. CONCLUSIONS: The women pregnant in 2012 framed their expectations in the language of choice, whilst the women who birthed in the 1970s-1980s framed their experience in the language of safety. For both, however, the world of birth was the same; saturated with, and only legitimised by the birth of a healthy baby. Rather than creating meaningful understanding, the 'idle talk' of birth made both cohorts fearful of leaving the relative comfort of the 'system', and of claiming an alternative birth
