Dropping the weight stigma: Nostalgia improves attitudes toward persons who are overweight

Weight stigma, a negative attitude toward persons who are overweight, can lead to emotional detriment (increased vulnerability to depression and anxiety, decreased self-esteem) and discriminatory practices (denial of employment, lower wages, refusal of job promotion or college admission, healthcare deprivation), which have increased dramatically in the United States over the past decade. We report two experiments that implicate nostalgia as a resource or strategy for weight stigma reduction. We hypothesized and found that nostalgia about an encounter with a person who is overweight improves attitudes toward the group "overweight." Undergraduates who recalled a nostalgic (vs. ordinary) interaction with an overweight person subsequently showed more positive outgroup attitudes. The effect of nostalgia on outgroup attitudes was mediated by greater inclusion of the outgroup in the self and increased outgroup trust (Experiments 1 and 2), as well as reduced intergroup anxiety and greater perceptions of a common ingroup identity (Experiment 2). The findings have interventional potential. (C) 2011 Elsevier Inc. All rights reserved.

The OpenPMU Platform for Open Source Phasor Measurements

OpenPMU is an open platform for the development of phasor measurement unit (PMU) technology. A need has been identified for an open-source alternative to commercial PMU devices tailored to the needs of the university researcher and for enabling the development of new synchrophasor instruments from this foundation. OpenPMU achieves this through open-source hardware design specifications and software source code, allowing duplicates of the OpenPMU to be fabricated under open-source licenses. This paper presents the OpenPMU device based on the Labview development environment. The device is performance tested according to the IEEE C37.118.1 standard. Compatibility with the IEEE C37.118.2 messaging format is achieved through middleware which is readily adaptable to other PMU projects or applications. Improvements have been made to the original design to increase its flexibility. A new modularized architecture for the OpenPMU is presented using an open messaging format which the authors propose is adopted as a platform for PMU research.

Vitamin D binding protein isoforms as candidate predictors of disease extension in childhood arthritis

Introduction: Juvenile idiopathic arthritis (JIA) comprises a poorly understood group of chronic autoimmune diseases with variable clinical outcomes. We investigated whether the synovial fluid (SF) proteome could distinguish a subset of patients in whom disease extends to affect a large number of joints.

Methods: SF samples from 57 patients were obtained around time of initial diagnosis of JIA, labeled with Cy dyes and separated by two-dimensional electrophoresis. Multivariate analyses were used to isolate a panel of proteins which distinguish patient subgroups. Proteins were identified using MALDI-TOF mass spectrometry with expression verified by immunochemical methods. Protein glycosylation status was confirmed by hydrophilic interaction liquid chromatography.

Results: A truncated isoform of vitamin D binding protein (VDBP) is present at significantly reduced levels in the SF of oligoarticular patients at risk of disease extension, relative to other subgroups (p < 0.05). Furthermore, sialylated forms of immunopurified synovial VDBP were significantly reduced in extended oligoarticular patients (p < 0.005).

Conclusion: Reduced conversion of VDBP to a macrophage activation factor may be used to stratify patients to determine risk of disease extension in JIA patients.

Trades Unions and the Transition away from 'actually existing unsustainability':From economic crisis to a new political economy beyond growth

Traditionally trades unions have accepted and promoted orthodox economic growth as a policy imperative. In recent years there has been a noticeable ‘greening’ of trade unions in relation to initiatives such as the ‘Green new deal’ and the creation of ‘green collar’ employment and the focus on a ‘just transition’ to a low carbon economy. Yet given the growing evidence of the negative impacts of economic growth in terms of environmental, resource and pollution impacts as well as the inability of economic growth to tackle (as opposed to managed) socio-economic inequality, it is timely to review the case for trades unions to fundamentally rethink the commitment to orthodox economic growth. That is, for trades unions to consider going beyond their current ‘green/sustainability’ strategies to consider more radical ‘post-growth’ policy positions. This chapter will explore some of the dimensions of a ‘post-growth’ trade union agenda by considering the evidence for going beyond growth from within the trade union movement (specifically looking at the International Labor Organization’s 2004 report on Economic Security, to internal union discussions around trades unionism and climate change) and external evidence ranging from Wilkinson and Pickett’s The Spirit Level (which suggests amongst other things that in the developed world what is needed is not economic growth but greater redistribution and lowering inequality – issues also of traditional interest to the Trades Union movement) to Tim Jackson’s Prosperity without Growth (which suggests that economic growth is ecologically unsustainable as well having passed a threshold beyond which it is contributing to human well-being in the developed world). As well as discussing the relationship between trades unionism and what may be called ‘green political economy’ (such as the ‘degrowth’ and ‘limits to growth’ perspectives) this chapter will also discuss the practical/policy implications of this ‘post-growth’ perspective in relation to trades unionism’s analysis of capitalism and its transformation in the context of a climate changed, carbon constrained world, including implications for ideas such as basic income, a shorter working week and what a trades unionism focused on how to achieve high quality of life within a low carbon context might look like.

flp-32 Ligand/Receptor Silencing Phenocopy Faster Plant Pathogenic Nematodes

Restrictions on nematicide usage underscore the need for novel control strategies for plant pathogenic nematodes such as Globodera pallida (potato cyst nematode) that impose a significant economic burden on plant cultivation activities. The nematode neuropeptide signalling system is an attractive resource for novel control targets as it plays a critical role in sensory and motor functions. The FMRFamide-like peptides (FLPs) form the largest and most diverse family of neuropeptides in invertebrates, and are structurally conserved across nematode species, highlighting the utility of the FLPergic system as a broad-spectrum control target. flp-32 is expressed widely across nematode species. This study investigates the role of flp-32 in G. pallida and shows that: (i) Gp-flp-32 encodes the peptide AMRNALVRFamide; (ii) Gp-flp-32 is expressed in the brain and ventral nerve cord of G. pallida; (iii) migration rate increases in Gp-flp-32-silenced worms; (iv) the ability of G. pallida to infect potato plant root systems is enhanced in Gp-flp-32-silenced worms; (v) a novel putative Gp-flp-32 receptor (Gp-flp-32R) is expressed in G. pallida; and, (vi) Gp-flp-32R silenced worms also display an increase in migration rate. This work demonstrates that Gp30 flp-32 plays an intrinsic role in the modulation of locomotory behaviour in G. pallida, and putatively interacts with at least one novel G-protein coupled receptor (Gp-flp-32R). This is the first functional characterisation of a parasitic nematode FLP-GPCR. © 2013 Atkinson et al.

The City as Laboratory and the Urban-Rural Divide: the Revival of Private Property and its Limits in Post-Mao China

This paper focuses on the revival of private property and its limits in urban China. It explores the emergence of urban property markets; urban property-holding in relation to the complexity of urban governance; “minor property rights apartments” that form a de facto real estate market and cross over the urban-rural divide; the “grey areas” of blurring legal and administrative boundaries in modern China; and recent changes to the rural land system and the rural-urban divide. The conclusion flags the theme of the city as laboratory with regard to the blurring legal and governmental urban-rural distinction.

The Houses of the Oireachtas:Parliament in Ireland

The Irish parliament - the Oireachtas - is nearing the centenary year of its foundation, making it one of the oldest continuously surviving parliaments in the world. As the most important national institution in the state, it plays an essential role in giving voice to a diversity of views and opinions, providing stable governments, approving law and national budgets and upholding democratic values. For much of its existence, however, and most pointedly in the context of recent banking and economic crises, it has been subject to criticism concerning its ability to adequately hold the executive to account, to act as a coherent policy-making forum, to meet the challenges arising from European Union membership, to embrace wide-ranging reforms and to develop with purpose and ambition.

This comprehensive new volume considers all aspects of the Houses of the Oireachtas - including their evolution, composition, organisation, financing, administration and reform. Contributors include academics, administrators and sitting and former parliamentarians. Contemporary challenges brought about by transformations in media style, increased inter-parliamentarism and the changing character of politics are also addressed. The book questions a number of assumptions about parliament and its work, including the efficacy of the legislative and budgetary processes, the nature of executive-legislative relations and the perceived encroachment of the courts on the legislature. Combined, this wide-ranging and detailed study fills a long-standing void, and provides essential reading not alone for those interested in Irish politics and government, but also for students and scholars of legislative studies.

Frontal EEG/ERP correlates of attentional processes, cortisol and motivational states in adolescents from lower and higher socioeconomic status

Event-related potentials (ERPs) and other electroencephalographic (EEG) evidence show that frontal brain areas of higher and lower socioeconomic status (SES) children are recruited differently during selective attention tasks. We assessed whether multiple variables related to self-regulation (perceived mental effort) emotional states (e.g., anxiety, stress, etc.) and motivational states (e.g., boredom, engagement, etc.) may co-occur or interact with frontal attentional processing probed in two matched-samples of fourteen lower-SES and higher-SES adolescents. ERP and EEG activation were measured during a task probing selective attention to sequences of tones. Pre- and post-task salivary cortisol and self-reported emotional states were also measured. At similar behavioural performance level, the higher-SES group showed a greater ERP differentiation between attended (relevant) and unattended (irrelevant) tones than the lower-SES group. EEG power analysis revealed a cross-over interaction, specifically, lower-SES adolescents showed significantly higher theta power when ignoring rather than attending to tones, whereas, higher-SES adolescents showed the opposite pattern. Significant theta asymmetry differences were also found at midfrontal electrodes indicating left hypo-activity in lower-SES adolescents. The attended vs. unattended difference in right midfrontal theta increased with individual SES rank, and (independently from SES) with lower cortisol task reactivity and higher boredom. Results suggest lower-SES children used additional compensatory resources to monitor/control response inhibition to distracters, perceiving also more mental effort, as compared to higher-SES counterparts. Nevertheless, stress, boredom and other task-related perceived states were unrelated to SES. Ruling out presumed confounds, this study confirms the midfrontal mechanisms responsible for the SES effects on selective attention reported previously and here reflect genuine cognitive differences.

Focused attention, heart rate deceleration, and cognitive development in preterm and full-term infants

The majority of children who are born very preterm escape major impairment, yet more subtle cognitive and attention problems are very common in this population. Previous research has linked infant focused attention during exploratory play to later cognition in children born full-term and preterm. Infant focused attention can be indexed by sustained decreases in heart rate (HR). However there are no preterm studies that have jointly examined infant behavioral attention and concurrent HR response during exploratory play in relation to developing cognition. We recruited preterm infants free from neonatal conditions associated with major adverse outcomes, and further excluded infants with developmental delay (Bayley Mental Development Index [MDI?

Cortisol, behavior, and heart rate reactivity to immunization pain at 4 months corrected age in infants born very preterm

Pain response may be altered in infants born very preterm owing to repeated exposure to procedures in the neonatal intensive care unit. Findings have been inconsistent in studies of behavioral and cardiac responses to brief pain in preterm versus full-term infants following neonatal intensive care unit discharge. To our knowledge, cortisol reactivity to pain has not been compared in preterm and full-term infants. We examined pain reactivity to immunization in preterm and full-term infants.

Prenatal effects of selective serotonin reuptake inhibitor antidepressants, serotonin transporter promoter genotype (SLC6A4), and maternal mood on child behavior at 3 years of age

To investigate whether prenatal selective serotonin reuptake inhibitor (SSRI) antidepressant exposure affects behavior in 3-year-olds of antenatally anxious or depressed mothers and whether risk was moderated by the serotonin transporter promoter (SLC6A4) genotype.
