An evaluation of portion size estimation aids precision, ease of use and likelihood of future use

OBJECTIVE: The present study aimed to evaluate the precision, ease of use and likelihood of future use of portion size estimation aids (PSEA).

DESIGN: A range of PSEA were used to estimate the serving sizes of a range of commonly eaten foods and rated for ease of use and likelihood of future usage.

SETTING: For each food, participants selected their preferred PSEA from a range of options including: quantities and measures; reference objects; measuring; and indicators on food packets. These PSEA were used to serve out various foods (e.g. liquid, amorphous, and composite dishes). Ease of use and likelihood of future use were noted. The foods were weighed to determine the precision of each PSEA.

SUBJECTS: Males and females aged 18-64 years (n 120).

RESULTS: The quantities and measures were the most precise PSEA (lowest range of weights for estimated portion sizes). However, participants preferred household measures (e.g. 200 ml disposable cup) - deemed easy to use (median rating of 5), likely to use again in future (all scored either 4 or 5 on a scale from 1='not very likely' to 5='very likely to use again') and precise (narrow range of weights for estimated portion sizes). The majority indicated they would most likely use the PSEA preparing a meal (94 %), particularly dinner (86 %) in the home (89 %; all P<0·001) for amorphous grain foods.

CONCLUSIONS: Household measures may be precise, easy to use and acceptable aids for estimating the appropriate portion size of amorphous grain foods.

Surviving the industrial city: the female poor and the workhouse in late nineteenth-century Belfast

In common with many British cities, but unlike the rest of Ireland, late nineteenth-century Belfast experienced rapid industrialization and physical expansion. Women formed a significant proportion of the city’s workforce, attracted by the employment opportunities represented in the burgeoning textile industry. Many of them were economically vulnerable, however, and could find themselves destitute for a number of reasons. This article sets Belfast’s Poor Law workhouse in the landscape of welfare in the city, exploring how its use reflected the development of the city and the ways in which the female poor engaged with it in order to survive.

Promoting healthy dietary behaviour through personalised nutrition: technology push or technology pull?

The notion of educating the public through generic healthy eating messages has pervaded dietary health promotion efforts over the years and continues to do so through various media, despite little evidence for any enduring impact upon eating behaviour. There is growing evidence, however, that tailored interventions such as those that could be delivered online can be effective in bringing about healthy dietary behaviour change. The present paper brings together evidence from qualitative and quantitative studies that have considered the public perspective of genomics, nutrigenomics and personalised nutrition, including those conducted as part of the EU-funded Food4Me project. Such studies have consistently indicated that although the public hold positive views about nutrigenomics and personalised nutrition, they have reservations about the service providers' ability to ensure the secure handling of health data. Technological innovation has driven the concept of personalised nutrition forward and now a further technological leap is required to ensure the privacy of online service delivery systems and to protect data gathered in the process of designing personalised nutrition therapies.

Measuring the shape of degree distributions

Degree distribution is a fundamental property of networks. While mean degree provides a standard measure of scale, there are several commonly used shape measures. Widespread use of a single shape measure would enable comparisons between networks and facilitate investigations about the relationship between degree distribution properties and other network features. This paper describes five candidate measures of heterogeneity and recommends the Gini coefficient. It has theoretical advantages over many of the previously proposed measures, is meaningful for the broad range of distribution shapes seen in different types of networks, and has several accessible interpretations. While this paper focusses on degree, the distribution of other node based network properties could also be described with Gini coefficients.

Phytoplankton and microbial plankton of the Bay of Biscay and Western Iberian Shelf

The region of the Northeast Atlantic represents a gradient between two oceanographic regimes: (i) the subtropical waters of southern Portugal and southwestern Spain, and (ii) the temperate waters characterizing the northwestern and northern Iberian coasts (Cantabrian Sea) and the rest of the Bay of Biscay along the French coast.

Loss of Aggressiveness of Phytophthora cinnamomi (Beta-Cinnamomin Silenced Strain) in the Infection of Castanea sativa

Several forest species are severely affected by Phytophthora cinnamomi. The contribution of this oomycete to forest decline and dieback has been broadly reported. In particular, it is consensual that it is the causal agent of ink disease in Castanea sativa. It has been associated with the severe decline of Quercus species, namely the Q. suber and Q. ilex dieback in Portugal and Spain, and has been responsible for the infection of numerous native species and crops. This pathogen persists in the soil or on plant material in the form of chlamydospores allowing the infection of living root tissues when environmental conditions are favorable. © Microscopy Society of America 2012.

Recension de "Revenu minimum garanti : comparaison internationale, analyses et débats’ par Lionel-Henri Groulx"

"La lutte contre la pauvreté et l’exclusion sociale est un enjeu qui hante constamment les débats politiques des pays occidentaux. L’ensemble des acteurs publics déplorent que, dans nos sociétés d’opulence, certains n’aient ni le minimum pour vivre ni la capacité d’exercer leurs droits sociaux. Dans son livre, Louis-Henri Groulx s’intéresse à une des stratégies pour lutter contre la pauvreté : le revenu minimum garanti. [...]"

A Service Model For Delivering Care Closer to Home.

Upton Surgery (Worcestershire) has developed a flexible and responsive service model that facilitates multi-agency support for adult patients with complex care needs experiencing an acute health crisis. The purpose of this service is to provide appropriate interventions that avoid unnecessary hospital admissions or, alternatively, provide support to facilitate early discharge from secondary care. Key aspects of this service are the collaborative and proactive identification of patients at risk, rapid creation and deployment of a reactive multi-agency team and follow-up of patients with an appropriate long-term care plan. A small team of dedicated staff (the Complex Care Team) are pivotal to coordinating and delivering this service. Key skills are sophisticated leadership and project management skills, and these have been used sensitively to challenge some traditional roles and boundaries in the interests of providing effective, holistic care for the patient. This is a practical example of early implementation of the principles underlying the Department of Health’s (DH) recent Best Practice Guidance, ‘Delivering Care Closer to Home’ (DH, July 2008) and may provide useful learning points for other general practice surgeries considering implementing similar models. This integrated case management approach has had enthusiastic endorsement from patients and carers. In addition to the enhanced quality of care and experience for the patient, this approach has delivered value for money. Secondary care costs have been reduced by preventing admissions and also by reducing excess bed-days. The savings achieved have justified the ongoing commitment to the service and the staff employed in the Complex Care Team. The success of this service model has been endorsed recently by the ‘Customer Care’ award by ‘Management in Practice’. The Surgery was also awarded the ‘Practice of the Year’ award for this and a number of other customer-focussed projects.

Case-series Evaluating a Transdiagnostic Cognitive-behavioral Treatment For Co-occurring Anxiety Disorders.

Background. Patients with anxiety disorder diagnoses commonly have more than one anxiety diagnosis. While cognitive-behavioral interventions have proven efficacy in treating single anxiety disorder diagnoses, there has been little investigation of their efficacy in treating cooccurring anxiety disorders. Aims. To evaluate the efficacy of a transdiagnostic cognitive-behavioral intervention for treating co-occurring anxiety disorders. Methods. An A-B single case study design (N = 6) was used to evaluate the efficacy of a 12 to 13 session modular transdiagnostic cognitive-behavioral intervention for treating co-occurring anxiety disorders across patients with at least two of the following diagnoses: GAD, Social Phobia, Panic Disorder and/or OCD. Results. Five of the six participants completed treatment. At post-treatment assessment the five treatment completers achieved diagnostic and symptomatic change with three participants being diagnosis free. All participants who completed treatment no longer met criteria for any DSM-IV-TR Axis-I diagnosis at the three-month follow-up assessment, and demonstrated reliable and clinically-significant improvements in symptoms. Across the participants, statistically significant improvements from pre- to post-intervention were found on measures of anxiety, depression and general well-being, and all improvements were maintained at three-month follow-up. Conclusions. Results suggest that transdiagnostic cognitive behavioral interventions can be of benefit to patients with co-occurring anxiety disorders.

Spatial justice: law and the geography of withdrawal

While spatial justice could be the most radical offspring of law’s recent spatial turn, it remains instead a geographically informed version of social justice. The majority of the existing literature on the subject has made some politically facile assumptions about space, justice and law, thereby subsuming the potentially radical into the banal. In this article, I suggest that the concept of spatial justice is the most promising platform on which to redefine, not only the connection between law and geography, but more importantly, the conceptual foundations of both law and space. More concretely, the article attempts two things: first, a radical understanding of legal spatiality. Space is not just another parameter for law, a background against which law takes place, or a process that the law needs to take into consideration. Space is intertwined with normative production in ways that law often fails to acknowledge, and part of this article is a re-articulation of the connection. Second, to suggest a conception of spatial justice that derives from a spatial law. Such a conception cannot rely on given concepts of distributive or social justice. Instead, the concept of spatial justice put forth here is informed by post-structural, feminist, post-ecological and other radical understandings of emplacement and justice, as well as arguably the most spatial of philosophical discourses, that of Deleuze–Guattari and the prescribed possibilities of space as manifold.

Reading Maud’s remains: Tennyson, geological processes, and palaeontological reconstructions

As Tennyson's “little Hamlet ,” Maud (1855) posits a speaker who, like Hamlet, confronts the ignominious fate of dead remains. Maud's speaker contemplates such remains as bone, hair, shell, and he experiences his world as one composed of hard inorganic matter, such things as rocks, gems, flint, stone, coal, and gold. While Maud's imagery of “stones, and hard substances” has been read as signifying the speaker's desire “unnaturally to harden himself into insensibility” (Killham 231, 235), I argue that these substances benefit from being read in the context of Tennyson's wider understanding of geological processes. Along with highlighting these materials, the text's imagery focuses on processes of fossilisation, while Maud's characters appear to be in the grip of an insidious petrification. Despite the preoccupation with geological materials and processes, the poem has received little critical attention in these terms. Dennis R. Dean, for example, whose Tennyson and Geology (1985) is still the most rigorous study of the sources of Tennyson's knowledge of geology, does not detect a geological register in the poem, arguing that by the time Tennyson began to write Maud, he was “relatively at ease with the geological world” (Dean 21). I argue, however, that Maud reveals that Tennyson was anything but “at ease” with geology. While In Memoriam (1851) wrestles with religious doubt that is both initiated, and, to some extent, alleviated by geological theories, it finally affirms the transcendence of spirit over matter. Maud, conversely, gravitates towards the ground, concerning itself with the corporal remains of life and with the agents of change that operate on all matter. Influenced by his reading of geology, and particularly Charles Lyell's provocative writings on the embedding and fossilisation of organic material in strata in his Principles of Geology (1830–33) volume 2, Tennyson's poem probes the taphonomic processes that result in the incorporation of dead remains and even living flesh into the geological system.

Morality and politics: the free churches and the Labour Party between the wars

The inter-war period saw the decline of the Liberal party, the traditional political ally of the free churches, and the rise of the Labour party. This article traces the responses of the free churches to these developments. The relationship of the free churches with the Labour party in this period is examined at three different levels; that of the free church leadership, that of the chapels and the ordinary people in the pews and that of the nonconformists who became active in the Labour party. Whilst attitudes towards the Labour party changed within free church institutions during the inter-war years they did not become important supporters of the party, or greatly influence it. The number and proportion of individual nonconformists who were active and influential in the party in this period was however considerable. In the process not only did Labour M.P.s become the main carriers of the nonconformist conscience on issues such as drink and gambling. They also made a distinctive and important contribution to the development and ideals of the Labour party.

Places and preferences: a longitudinal analysis of self-selection and contextual effects

Contextual theories of political behaviour assert that the contexts in which people live influence their political beliefs and vote choices. Most studies of political assimilation, however, rely on cross-sectional data and fail to distinguish contextual influence from self-selection of individuals into areas. This paper advances understanding of this longstanding controversy by tracking thousands of individuals over an 18-year period in England. We observe individual-level left-right position and party identification before and after residential moves across areas with different political orientations. We find evidence of both non-random selection into areas and assimilation of new entrants to the majority political orientation. However, these effects are contingent on the type of area an individual moves to and, moreover, contextual effects are weak and dominated by the larger effect of self-selection into areas.
