The Deserving Poor, the Family, and the U.S. Welfare System
Authors: Moffitt Robert A. 
Published: June 2015

AbstractContrary to the popular view that the U.S. welfare system has been in a contractionary phase after the expansions of the welfare state in the 1960s, welfare spending resumed steady growth after a pause in the 1970s. However, although aggregate spending is higher than ever, there have been redistributions away from non-elderly and nondisabled families to families with older adults and to families with recipients of disability programs; from non-elderly, nondisabled single-parent families to married-parent families; and from the poorest families to those with higher incomes. These redistributions likely reflect long-standing, and perhaps increasing, conceptualizations by U.S. society of which poor are deserving and which are not.

AbstractIntroductionLumosity's Memory Match (LMM) is an online game requiring visual working memory. Change in LMM scores may be associated with individual differences in age‐related changes in working memory.MethodsEffects of age and time on LMM learning and forgetting rates were estimated using data from 1890 game sessions for users aged 40 to 79 years.ResultsThere were significant effects of age on baseline LMM scores (β = −.31, standard error or SE = .02,P < .0001) and lower learning rates (β = −.0066, SE = .0008,P < .0001). A sample size of 202 subjects/arm was estimated for a 1‐year study for subjects in the lower quartile of game performance.DiscussionOnline memory games have the potential to identify age‐related decline in cognition and to identify subjects at risk for cognitive decline with smaller sample sizes and lower cost than traditional recruitment methods.
Left Behind: Subjecthood, Nationality, and the Status of Jews after the Loss of English Surinam
Authors: Selwood Jacob 
Published: June 2015

AbstractFollowing the loss of Surinam to the Netherlands in 1667, the English Crown attempted to evacuate those of its subjects living in the colony under Dutch rule. In doing so, its representatives laid claim to members of the Jewish population, who Surinam's English governors had previously declared to be “considered as English-born.” In the resulting dispute between the English and Dutch over who could be removed, Crown officials embraced articulations of subjecthood forged in the colony that differed from metropolitan norms. In asserting that Surinam's Jews remained subjects of the king, and by implying that they would continue to do so once evacuated, the English delegation departed from the Crown's frequent rejection of the wider efficacy of colonial naturalization. Surinam's Dutch governor, meanwhile, dismissed the assertion that members of the “Hebrew nation” could be subjects of an English king, arguing that subjecthood and nationality were identical and that only those of the English nation could be removed. The dispute between the English and the Dutch over the status of Surinam's Jews reminds us that English subjecthood was shaped by colonial settings and by the contested status of groups who found themselves transferred between imperial powers.
Republicans, Martyrology, and the Death Penalty in Britain and Ireland, 1939–1990
Authors: Doyle David Matthew 
Published: June 2015

AbstractThis article examines the relationship between politically motivated murder, martyrdom, and the death penalty in Britain and Ireland in the period from 1939 to 1990. First, it investigates the nexus between historical experience and memory, political martyrdom, and capital punishment as it applied to Irish Republicans in Britain during the Second World War. Secondly, it examines the use of extraordinary legal powers to impose the death penalty in the Irish state during the “Emergency,” and charts the processes through which the threat of capital punishment continued to be perceived as an essential instrument of security in both Irish jurisdictions in the postwar period. Thirdly, it evaluates the effectiveness of the death penalty in deterring politically motivated murder and explores the anomalous, paradoxical decision to abolish capital punishment at the height of subversive killing in Northern Ireland. The essay concludes that the national security issue and the potential martyrdom of Irish Republicans were pivotal factors in dissuading successive British governments from reintroducing the death penalty for politically motivated offenses in Britain and Northern Ireland.
Modelling of confined vortex rings
Authors: Danaila Ionut , Kaplanski Felix , Sazhin Sergei 
Published: June 2015

This paper is focused on the investigation of vortex rings evolving in a tube. A new theoretical model for a confined axisymmetric vortex ring is developed. The predictions of this model are shown to be in agreement with available experimental data and numerical simulations. The model combines the viscous vortex ring model, developed by Kaplanski & Rudi (Phys. Fluids, vol. 17, 2005, 087101), with Brasseur’s (PhD thesis, Stanford University) approach to deriving a wall-induced streamfunction correction. Using the power-law assumption for the time variation of the viscous length of the vortex ring, the time variations of the main integral characteristics, circulation, kinetic energy and translational velocity are obtained. Direct numerical simulation (DNS) is used to test the range of applicability of the model and to investigate new physical features of confined vortex rings recently reported in the experimental study by Stewart et al. (Exp. Fluids, vol. 53, 2012, pp. 163–171). The model is shown to lead to a very good approximation of the spatial distribution of the Stokes streamfunction, obtained by DNS. The vortex signature and the time evolution of the energy of the vortex are also accurately predicted by the model. A procedure for fitting the model with realistic vortex rings, obtained by DNS, is suggested. This opens the way to using the model for practical engineering applications.
Balancing Formality and Informality in Business Exchanges as a Duality: A Comparative Case Study of Returnee and Local Entrepreneurs in China
Authors: Lin Daomi , Lu Jiangyong , Li Peter Ping , Liu Xiaohui 
Published: June 2015

ABSTRACTThe management paradigms in the West mainly rely on legal contracts and explicit rules (formality), while the management traditions in the East emphasize social relationships and implicit norms (informality). In an era of ‘West-meets-East’, balancing formality and informality is becoming critical for firms, especially those facing institutional differences in transnational contexts and institutional transitions. In this research, we conducted a comparative multicase study on returnee entrepreneurs and local entrepreneurs in China. We found that at the early stage of venturing, returnee entrepreneurs emphasized formality more than informality, while local entrepreneurs stressed informality more than formality. However, the formality-informality balance among both returnee and local entrepreneurs converged over time in line with the institutional transition in China. Returnee entrepreneurs increased the emphasis on informality (but kept the dominant position of formality), whereas local entrepreneurs gradually shifted from informality to formality. The spatial pattern of asymmetrical balancing and the temporal pattern of transitional balancing are both rooted in the Chinese philosophy of Yin-Yang balancing.

Published: June 2015

AbstractObjectives:To describe a method of using real patients in teaching ENT to undergraduates and to examine whether being a case patient affected patient satisfaction.Methods:In a cross-sectional study, 68 teaching-involved patients (case patients) with a suspected common ENT illness and 68 matched (in terms of age, sex and region of complaint) control patients evaluated the health service and their encounter with the physician. The students saw the case patients first independently and then saw the patient with the teacher physician. The controls were treated in a normal way.Results:Fifty-eight case patients (84 per cent) and 65 control patients (95 per cent) answered the questionnaire. The median duration of the visit was significantly longer for the case patients than the controls (115 vs 60 minutes). Almost all patients in both groups graded the overall quality of the health service, and the variables describing various aspects of the setting and the encounter with the physician, as either good or excellent.Conclusion:Patients who took part in the undergraduate teaching of ENT diseases were equally content with their primary visit as the control patients, even though their visit took a markedly longer time.
(Ton)silly seasons? Do atmospheric conditions actually affect post-tonsillectomy secondary haemorrhage rates?
Authors: Cadd B , Rogers M , Patel H , Crossland G 
Published: June 2015

AbstractBackground:Tonsillectomy is a common procedure, with potentially life-threatening complications. Previous investigations into post-tonsillectomy secondary haemorrhage rates suggest an influence of climactic and atmospheric conditions on haemorrhage rate, particularly temperature and water vapour pressure. With a single emergency department and a large variance in atmospheric conditions, Darwin, Australia, is ideal for investigating the effects of local climate on rates of post-operative haemorrhage.Methods:A five-year retrospective review was conducted of all tonsillectomy procedures performed between 2008 and 2013. Effects of atmospheric variables were examined using Pearson's correlation coefficient and analysis of variance.Results:A total of 941 patients underwent tonsillectomy in the study period. The bleeding rate was 7.7 per cent. No variation was found between wet and dry season tonsillectomies (p= 0.4). Temperature (p= 0.74), water vapour pressure (p= 0.94) and humidity (p= 0.66) had no effect on bleeding.Conclusion:The findings revealed no correlation between humidity, season, water vapour pressure and haemorrhage rates. Further research should use multi-site data to investigate the effect of air conditioning, humidification and climactic conditions between different regions in Australia.
Does the Relative Strength of Grouping Principles Modulate the Interactions between them?
Authors: Montoro Pedro R. , Luna Dolores 
Published: June 2015

AbstractThis study examines the influence of the relative strength of grouping principles on interactions between the intrinsic principle of proximity and the extrinsic principle of common region in the process of perceptual organization. Cooperation and competition between intrinsic and extrinsic principles were examined by presenting the principle either alone or conjoined with another principle. The relative grouping strength of the principles operating alone was varied in two different groups of participants so that it was similar for one group and very different for the other group. Results showed that, when principles acting alone had different strengths, the grouping effect of the strongest principle was similar to that of the cooperation condition, and the effect of the weakest principle was similar to that of competing conjoined principles. In contrast, when the strength of principles acting alone was similar, the effect of conjoined cooperating principles was greater than that of either principle acting alone. Moreover, the effect of conjoined competing principles was smaller than that of either principle operating alone. Results show that cooperation and competition between intrinsic and extrinsic principles are modulated by the relative grouping strength of principles acting alone. Furthermore, performance in these conditions could be predicted on the basis of performance in single-principle conditions.

Abstract
The high diversity of microbial communities hampers predictions about their responses to global change. Here we investigate the potential for using a phylogenetic, trait-based framework to capture the response of bacteria and fungi to global change manipulations. Replicated grassland plots were subjected to 3+ years of drought and nitrogen fertilization. The responses of leaf litter bacteria and fungi to these simulated changes were significantly phylogenetically conserved. Proportional changes in abundance were highly correlated among related organisms, such that relatives with approximately 5% ribosomal DNA genetic distance showed similar responses to the treatments. A microbe’s change in relative abundance was significantly correlated between the treatments, suggesting a compromise between numerical abundance in undisturbed environments and resistance to change in general, independent of disturbance type. Lineages in which at least 90% of the microbes shared the same response were circumscribed at a modest phylogenetic depth (τD 0.014–0.021), but significantly larger than randomized simulations predict. In several clades, phylogenetic depth of trait consensus was higher. Fungal response to drought was more conserved than was response to nitrogen fertilization, whereas bacteria responded equally to both treatments. Finally, we show that a bacterium’s response to the manipulations is correlated with its potential functional traits (measured here as the number of glycoside hydrolase genes encoding the capacity to degrade different types of carbohydrates). Together, these results suggest that a phylogenetic, trait-based framework may be useful for predicting shifts in microbial composition and functioning in the face of global change.
High-efficient thermoelectric materials: The case of orthorhombic IV-VI compounds
Authors: Ding Guangqian , Gao Guoying , Yao Kailun 
Published: June 2015

AbstractImproving the thermoelectric efficiency is one of the greatest challenges in materials science. The recent discovery of excellent thermoelectric performance in simple orthorhombic SnSe crystal offers new promise in this prospect [Zhao et al. Nature 508, 373 (2014)]. By calculating the thermoelectric properties of orthorhombic IV-VI compounds GeS,GeSe,SnS and SnSe based on the first-principles combined with the Boltzmann transport theory, we show that the Seebeck coefficient, electrical conductivity and thermal conductivity of orthorhombic SnSe are in agreement with the recent experiment. Importantly, GeS, GeSe and SnS exhibit comparative thermoelectric performance compared to SnSe. Especially, the Seebeck coefficients of GeS, GeSe and SnS are even larger than that of SnSe under the studied carrier concentration and temperature region. We also use the Cahill's model to estimate the lattice thermal conductivities at the room temperature. The large Seebeck coefficients, high power factors and low thermal conductivities make these four orthorhombic IV-VI compounds promising candidates for high-efficient thermoelectric materials.
Efficient in vitro generation of functional thymic epithelial progenitors from human embryonic stem cells

Published: June 2015

AbstractThymic epithelial cells (TECs) are the major components of the thymic microenvironment for T cell development. TECs are derived from thymic epithelial progenitors (TEPs). It has been reported that human ESCs (hESCs) can be directed to differentiate into TEPs in vitro. However, the efficiency for the differentiation is low. Furthermore, transplantation of hESC-TEPs in mice only resulted in a very low level of human T cell development from co-transplanted human hematopoietic precursors. We show here that we have developed a novel protocol to efficiently induce the differentiation of hESCs into TEPs in vitro. When transplanted into mice, hESC-TEPs develop into TECs and form a thymic architecture. Most importantly, the hESC-TECs support the long-term development of functional mouse T cells or a higher level of human T cell development from co-transplanted human hematopoietic precursors. The hESC-TEPs may provide a new approach to prevent or treat patients with T cell immunodeficiency.

Published: June 2015

AbstractRecent clinical evidence suggests that the therapeutic effect of massage involves the immune system and that this can be exploited as an adjunct therapy together with standard drug-based approaches. In this study, we investigated the mechanisms behind these effects exploring the immunomodulatory function of stroking as a surrogate of massage-like therapy in mice. C57/BL6 mice were stroked daily for 8 days either with a soft brush or directly with a gloved hand and then analysed for differences in their immune repertoire compared to control non-stroked mice. Our results show that hand- but not brush-stroked mice demonstrated a significant increase in thymic and splenic T cell number (p < 0.05; p < 0.01). These effects were not associated with significant changes in CD4/CD8 lineage commitment or activation profile. The boosting effects on T cell repertoire of massage-like therapy were associated with a decreased noradrenergic innervation of lymphoid organs and counteracted the immunosuppressive effect of hydrocortisone in vivo. Together our results in mice support the hypothesis that massage-like therapies might be of therapeutic value in the treatment of immunodeficiencies and related disorders and suggest a reduction of the inhibitory noradrenergic tone in lymphoid organs as one of the possible explanations for their immunomodulatory function.

AbstractChronic airway infections caused by Pseudomonas aeruginosa contribute to the progression of pulmonary disease in individuals with cystic fibrosis (CF). In the setting of CF, within-patient adaptation of a P. aeruginosa strain generates phenotypic diversity that can complicate microbiological analysis of patient samples. We investigated within- and between- sample diversity of 34 phenotypes among 235 P. aeruginosa isolates cultured from sputum samples collected from a single CF patient over the span of one year and assessed colony morphology as a screening tool for predicting phenotypes, including antimicrobial susceptibilities. We identified 15 distinct colony morphotypes that varied significantly in abundance both within and between sputum samples. Substantial within sample phenotypic heterogeneity was also noted in other phenotypes, with morphotypes being unreliable predictors of antimicrobial susceptibility and other phenotypes. Emergence of isolates with reduced susceptibility to β-lactams was observed during periods of clinical therapy with aztreonam. Our findings confirm that the P. aeruginosa population in chronic CF lung infections is highly dynamic and that intra-sample phenotypic diversity is underestimated if only one or few colonies are analyzed per sample.
Bessel beam CARS of axially structured samples

Published: June 2015

AbstractWe report about a Bessel beam CARS approach for axial profiling of multi-layer structures. This study presents an experimental implementation for the generation of CARS by Bessel beam excitation using only passive optical elements. Furthermore, an analytical expression is provided describing the generated anti-Stokes field by a homogeneous sample. Based on the concept of coherent transfer functions, the underling resolving power of axially structured geometries is investigated. It is found that through the non-linearity of the CARS process in combination with the folded illumination geometry continuous phase-matching is achieved starting from homogeneous samples up to spatial sample frequencies at twice of the pumping electric field wave. The experimental and analytical findings are modeled by the implementation of the Debye Integral and scalar Green function approach. Finally, the goal of reconstructing an axially layered sample is demonstrated on the basis of the numerically simulated modulus and phase of the anti-Stokes far-field radiation pattern.
Systemic high-mobility group box 1 administration suppresses skin inflammation by inducing an accumulation of PDGFRα+ mesenchymal cells from bone marrow

Published: June 2015

AbstractHigh-mobility group box 1 (HMGB1) mobilizes platelet-derived growth factor receptor alpha-positive (PDGFRα+) mesenchymal cells from bone marrow (BM) into circulation. However, whether HMGB1-induced endogenous PDGFRα+ mesenchymal cells stimulate skin regeneration has been unclear. Here, we investigated the functions of the HMGB1/BM-PDGFRα+ mesenchymal cell axis in the regeneration of mouse skin grafts. We found that intravenous HMGB1 administration induced an accumulation of endogenous BM-PDGFRα+ mesenchymal cells followed by significant inflammatory suppression in the grafts. In contrast, mice with reduced BM-PDGFRα+ mesenchymal cells showed massive inflammation of the grafts compared to mice that had normal levels of these cells even after HMGB1 administration, suggesting that BM-PDGFRα+ mesenchymal cells contribute to the HMGB1-induced anti-inflammatory effect. We also found that intravenously administered HMGB1 augmented the local migration of BM-PDGFRα+ mesenchymal cells from circulation to skin graft by inducing the expression of CXCR4, an SDF-1 receptor, on these cells. Finally, we showed the therapeutic activity of the HMGB1/BM-PDGFRα+ mesenchymal cell axis in an allergic contact dermatitis model. The results illustrated the contribution of the HMGB1/BM-PDGFRα+ mesenchymal cell axis in suppressing the inflammation of injured/inflamed skin. These findings may provide future perspectives on the use of HMGB1-based medicines for intractable diseases.
