Authors: Mahmud Mir Hasan Shakil , Yeasmin Bushra , Mandal Shipra
Published: June 2017

Schizophrenia is one of the major mental disorders which affect individuals thinking ability, social interaction or attention. It affects persons entire quality of life. The purpose of the study was to find out the quality of life of schizophrenic patient in Bangladesh. Cross sectional study design was used to conduct this study. The convenient sampling procedure was used throughout the process of participants selection and the numbers of respondents were 83. The study was carried out at National Institute of Mental Health and Hospital (NIMH), Dhaka. Data was collected by using face to face interview with a structured questionnaire WHOQOL-BREF (The World Health Organization Quality of Life- BREF) scale. It was found that most of the participants lead poor to moderate quality of life in four domains of the WHOQOL-BREF scale. Results showed that mean scores were for physical health (mean 2.7, SD+0.106); psychological health (mean 2.108, SD +0.0787); social relationship (mean 2.226; SD+0.116) and environmental health (mean 2.47; SD+0.077).This study indicated that, quality of life poor on psychological domain. It was also found statistically significance with age and social relationship domain (p value 0.005< 0.05); marital status and physical health domain (p value 0.004<0.05); educational level and physical health domain (p value 0.005<0.05) and environmental health domain (p value 0.025<0.05). There were no statistically significant difference between gender and other variables. Schizophrenia affects all aspects of persons life such as physically, psychologically, socially and economically. Schizophrenic patients as well as their family members led very poor quality of life.Bang J Psychiatry June 2015; 29(1): 30-34
Thermal Management of Concentrated Multi-Junction Solar Cells with Graphene-Enhanced Thermal Interface Materials
Authors: Saadah Mohammed , Hernandez Edward , Balandin Alexander
Published: June 2017

We report results of experimental investigation of temperature rise in concentrated multi-junction photovoltaic solar cells with graphene-enhanced thermal interface materials. Graphene and few-layer graphene fillers, produced by a scalable environmentally-friendly liquid-phase exfoliation technique, were incorporated into conventional thermal interface materials. Graphene-enhanced thermal interface materials have been applied between a solar cell and heat sink to improve heat dissipation. The performance of the multi-junction solar cells has been tested using an industry-standard solar simulator under a light concentration of up to 2000 suns. It was found that the application of graphene-enhanced thermal interface materials allows one to reduce the solar cell temperature and increase the open-circuit voltage. We demonstrated that the use of graphene helps in recovering a significant amount of the power loss due to solar cell overheating. The obtained results are important for the development of new technologies for thermal management of concentrated photovoltaic solar cells.
Effects of Thinning on Soil Organic Carbon Fractions and Soil Properties in Cunninghamia lanceolata Stands in Eastern China
Authors: Cheng Xiangrong , Yu Mukui , Wang G.
Published: June 2017

Soil organic carbon (SOC) fractions, along with soil properties, are greatly affected by forest management. In this study, three thinning treatments: control (conventional management mode), moderate thinning intensity and heavy thinning intensity, were applied in Chinese fir (Cunninghamia lanceolata) plantations in eastern China. The dissolved organic carbon (DOC), soil light fraction organic carbon (LFOC) and heavy fraction organic carbon (HFOC), total SOC, DOC/SOC and LFOC/HFOC were not affected by thinning treatments. In the heavy thinning treatment, soil bulk density decreased, and soil water holding capacity and porosity increased in the topsoil layers (0–10 cm and 10–20 cm). Total nitrogen, hydrolysable nitrogen, and zinc concentrations increased in the topsoil layers (0–20 cm) in the heavy thinning treatment compared to the control treatment, while the available potassium concentration reduced. The moderate thinning treatment had little effect on the soil physical and chemical properties. Moreover, the variation of SOC fractions was strongly correlated to soil physical and chemical properties. These results suggest that thinning has little effect on the total SOC and its fractions in one rotation of Chinese fir tree in eastern China. In contrast, however, results also suggest that thinning has a positive effect on soil quality, to a certain extent.
Effects of Perceived Neighbourhood Environments on Self-Rated Health among Community-Dwelling Older Chinese
Authors: Wong Moses , Yu Ruby , Woo Jean
Published: June 2017

In response to the growing number of older people living in cities, the World Health Organization (WHO) introduced the concept of “Age-Friendly Cities” (AFC) to guide the way in designing physical and social environments to encourage active ageing. Limited research has studied the effects of neighbourhood age-friendliness on elderly health outcomes. Using the example of a highly urbanized city in Asia, this study examined the effects of perceived age-friendliness of neighbourhood environments on self-rated health (SRH) among community-dwelling older Chinese. A multi-stage sampling method was used to collect views of community-dwelling older people from two local districts of Hong Kong. A structured questionnaire covering the WHO’s eight AFC domains was developed to collect information on the perceived neighbourhood environments, SRH and individual characteristics. Age-friendliness of neighbourhood was assessed by mean scores of AFC domains, which was used to predict SRH with adjustment for individual and objective neighbourhood characteristics. Furthermore, 719 respondents aged ≥60 years completed the questionnaire, of which 44.5% reported good SRH. Independent of individual and objective neighbourhood characteristics, multiple logistics regressions showed that higher satisfaction on outdoor spaces and buildings, transportation, housing, social participation, and respect and social inclusion was significantly associated with increased odds of reporting good SRH by more than 20% (p < 0.05). Individuals aged 70–79 years, being female, lower education and residents of public or subsidized housing were less likely to report good SRH, after controlling for individual and neighbourhood characteristics. In addition to age, gender, education and housing type, AFC environments have important contributive influence on SRH, after controlling for individual and objective neighbourhood characteristics.

Published: June 2017

Uncertainty still exists regarding the role of some environmental risk in the development of type 1 diabetes mellitus (T1DM) both globally and in Egypt. The objective here was to explore the potential environmental risk factors associated with the development of T1DM among children in Egypt. A case-controlled study of 204 T1DM children and an equal number of age and sex-matched controls was conducted in Assiut, Egypt. Data regarding the parental, gestational, neonatal, and childhood possible risk factors for T1DM were evaluated. The final sex adjusted multivariable logistic regression model revealed that the risk for T1DM was significantly higher among rural residents (aOR = 2.03, 95% CI: 1.30–4.25), those with parental history of T1DM (aOR = 9.03, 95% CI: 1.02–83.32), birth through cesarean section (aOR = 2.13, 95% CI: 1.09–5.03), and having history of early introduction of cow milk in the first year of life (aOR = 19.49, 95% CI: 8.73–45.53). On the other hand, a protective effect was observed between at least six months’ breastfeeding, vitamin D supplementation in the first year of life, high physical activity, and the development of T1DM. Educational programs should be adopted to improve awareness and knowledge of the parents to avoid the increased risk factors and encourage protective practices.
Depigmenting Effect of Resveratrol Is Dependent on FOXO3a Activation without SIRT1 Activation
Authors: Kwon Soon-Hyo , Choi Hye-Ryung , Kang Youn-A , Park Kyoung-Chan
Published: June 2017

Resveratrol exhibits not only anti-melanogenic property by inhibiting microphthalmia-associated transcription factor (MITF), but also anti-aging property by activating sirtuin-1 (SIRT1). In this study, the relationship between depigmenting effect of resveratrol and SIRT1/forkhead box O (FOXO) 3a activation and was investigated. Resveratrol suppressed melanogenesis by the downregulation of MITF and tyrosinase via ERK pathway. Results showed that the expression of both SIRT1 and FOXO3a were increased. It is reported that SIRT1 is critical regulator of FOXO-mediated transcription in response to oxidative stress. However in our study, FOXO3a activation appeared earlier than that of SIRT1. Furthermore, the effect of resveratrol on the levels of MITF and tyrosinase was suppressed when melanocytes were pre-treated with SP600125 (JNK inhibitor). However, pre-treatment with SIRT1 inhibitor (EX527, or sirtinol) did not affect the levels of MITF and tyrosinase. Therefore, resveratrol inhibits melanogenesis through the activation of FOXO3a but not by the activation of SIRT1. Although SIRT1 activation by resveratrol is a well-known mechanism of resveratrol-induced antiaging effects, our study showed that not SIRT1 but FOXO3a activation is involved in depigmenting effects of resveratrol.
Development of Temperature Control Solutions for Non-Instrumented Nucleic Acid Amplification Tests (NINAAT)
Authors: Pardy Tamás , Rang Toomas , Tulp Indrek
Published: June 2017

Non-instrumented nucleic acid amplification tests (NINAAT) are a novel paradigm in portable molecular diagnostics. They offer the high detection accuracy characteristic of nucleic acid amplification tests (NAAT) in a self-contained device, without the need for any external instrumentation. These Point-of-Care tests typically employ a Lab-on-a-Chip for liquid handling functionality, and perform isothermal nucleic acid amplification protocols that require low power but high accuracy temperature control in a single well-defined temperature range. We propose temperature control solutions based on commercially available heating elements capable of meeting these challenges, as well as demonstrate the process by which such elements can be fitted to a NINAAT system. Self-regulated and thermostat-controlled resistive heating elements were evaluated through experimental characterization as well as thermal analysis using the finite element method (FEM). We demonstrate that the proposed solutions can support various NAAT protocols, as well as demonstrate an optimal solution for the loop-mediated isothermal amplification (LAMP) protocol. Furthermore, we present an Arduino-compatible open-source thermostat developed for NINAAT applications.
Anti-Inflammatory and Antioxidant Properties of Peptides Released from β-Lactoglobulin by High Hydrostatic Pressure-Assisted Enzymatic Hydrolysis
Authors: Bamdad Fatemeh , Bark Seonghee , Kwon Chul Hee , Suh Joo-Won , Sunwoo Hoon
Published: June 2017

Background: β-lactoglobulin hydrolysates (BLGH) have shown antioxidant, antihypertensive, antimicrobial, and opioid activity. In the current study, an innovative combination of high hydrostatic pressure and enzymatic hydrolysis (HHP–EH) was used to increase the yield of short bioactive peptides, and evaluate the anti-inflammatory and antioxidant properties of the BLGH produced by the HHP–EH process. Method: BLG was enzymatically hydrolyzed by different proteases at an enzyme-to-substrate ratio of 1:100 under HHP (100 MPa) and compared with hydrolysates obtained under atmospheric pressure (AP-EH at 0.1 MPa). The degree of hydrolysis (DH), molecular weight distribution, and the antioxidant and anti-inflammatory properties of hydrolysates in chemical and cellular models were evaluated. Results: BLGH obtained under HHP–EH showed higher DH than the hydrolysates obtained under AP-EH. Free radical scavenging and the reducing capacity were also significantly stronger in HHP-BLGH compared to AP-BLGH. The BLGH produced by alcalase (Alc) (BLG-Alc) showed significantly higher antioxidant properties among the six enzymes examined in this study. The anti-inflammatory properties of BLG-HHP-Alc were observed in lipopolysaccharide-stimulated macrophage cells by a lower level of nitric oxide production and the suppression of the synthesis of pro-inflammatory cytokines. Peptide sequencing revealed that 38% of the amino acids in BLG-HHP-Alc are hydrophobic and aromatic residues, which contribute to its anti-inflammatory properties. Conclusions: Enzymatic hydrolysis of BLG under HHP produces a higher yield of short bioactive peptides with potential antioxidant and anti-inflammatory effects.

Published: June 2017

This study aimed to evaluate the intake of food and nutrients among primary, middle, and high schools students in Shanghai, and provide recommendations for possible amendments in new school lunch standards of Shanghai. Twenty schools were included in the school lunch menu survey. Of those, seven schools enrolled 5389 students and conducted physical measurement of plate waste and a questionnaire survey. The amount of food and nutrients was compared according to the new China National Dietary Guideline for School Children (2016) and Chinese Dietary Reference Intakes (2013). The provision of livestock and poultry meat in menus was almost 5–8 times the recommended amount. The amount of seafood was less than the recommended amount, and mostly came from half-processed food. The average percentage of energy from fat was more than 30% in students of all grades. The greatest amount of food wasted was vegetables with 53%, 42%, and 31%, respectively, among primary, middle and high school students. Intake of Vitamin A, Vitamin B2, calcium, and iron was about 50% of the recommended proportion. Only 24.0% students were satisfied with the taste of school lunches. Higher proportions of livestock and poultry meat and low intake of vegetables have become integral problems in school lunch programs. Additionally, more attention needs to be paid to the serving size in primary schools with five age groups.

Genistein, a soy-derived isoflavone, may improve cardiovascular risk profile in postmenopausal women with metabolic syndrome (MetS), but few literature data on its cardiac effects in humans are available. The aim of this sub-study of a randomized double-blind case-control study was to analyze the effect on cardiac function of one-year genistein dietary supplementation in 22 post-menopausal patients with MetS. Participants received 54 mg/day of genistein (n = 11) or placebo (n = 11) in combination with a Mediterranean-style diet and regular exercise. Left ventricular (LV) systolic function was assessed as the primary endpoint, according to conventional and strain-echocardiography measurements. Also, left atrial (LA) morphofunctional indices were investigated at baseline and at the final visit. Results were expressed as median with interquartile range (IQ). A significant improvement of LV ejection fraction (20.3 (IQ 12.5) vs. −1.67 (IQ 24.8); p = 0.040)), and LA area fractional change (11.1 (IQ 22.6) vs. 2.8 (9.5); p = 0.034)) were observed in genistein patients compared to the controls, following 12 months of treatment. In addition, body surface area indexed LA systolic volume and peak LA longitudinal strain significantly changed from basal to the end of the study in genistein-treated patients. One-year supplementation with 54 mg/day of pure genistein improved both LV ejection fraction and LA remodeling and function in postmenopausal women with MetS.
Toward a Romanian NPOs Sustainability Model: Determinants of Sustainability
Authors: Ceptureanu Sebastian-Ion , Ceptureanu Eduard-Gabriel , Orzan Mihai , Marin Irinel
Published: June 2017

Non-profit organizations (NPOs) have become increasingly important in the last decade for Romanian society since the state often failed to fulfill some of its social responsibilities. Romania’s economic and financial crisis several years ago hardly hit non-profit sector because it led to a significant drop in public spending at the government level and cuts of financing programs from companies, two main donors for NPOs while simultaneously has amplified society’s problems and gave rise to new target groups requiring support. This led to an acute need to address sustainability at organizational level since existing sustainability models in the literature are hardly adequate for Romanian context. We developed a model based on literature survey and Romanian experts’ interviews, which allow us to identify relevant factors for Romanian non-profit sustainability. Three determinants were considered: Cognitive competence (nine items analyzed), Social awareness (seven items analyzed) and Financial vulnerability (four items analyzed), as well as two types of results: economic and social. The model was tested through an empirical research on 103 Romanian NPOs and on two sub-samples (nongovernment organizations and community based organizations) and found, using univariate and bivariate analysis, that the three considered determinants are correlated and statistically influence Romanian NPOs sustainability.
Innovating Responsibly in ICT for Ageing: Drivers, Obstacles and Implementation
Authors: Chatfield Kate , Iatridis Konstantinos , Stahl Bernd , Paspallis Nearchos
Published: June 2017

Responsible research and innovation (RRI) is a nascent concept, promoted actively by the European Union and other policy makers around the world. Hitherto, this concept has been associated primarily with publicly funded activities but given the considerable proportion of research and innovation that is undertaken in the private sector, RRI will be rendered irrelevant unless it is adopted by industry. This paper introduces a private sector perspective of RRI, specifically that of the information and communication technology (ICT) industry, working in the field of healthy ageing. Drawing upon empirical data from 30 in-depth interviews with key industry representatives from across Europe, it explores: (a) the level of awareness of RRI; (b) the drivers and obstacles influencing its implementation; and (c) the factors deemed vital for facilitation of RRI in industry. The findings paint a varied picture, including significant concerns about adoption of RRI in an industry environment where the economic implications of all activities must be considered carefully. However, some companies have found their own ways to balance financial and altruistic goals, suggesting that there is both a willingness and a place for an RRI-type governance framework within the private sector.
The Assessment of Real Estate Initiatives to Be Included in the Socially-Responsible Funds
Authors: Battisti Fabrizio , Guarini Maria , Chiovitti Anthea
Published: June 2017

The acknowledgment of the ongoing economic and financial crisis involving real estate, creates the need to formulate proposals and scenarios (in real estate) with the characteristics of socially responsible investments. These kind of investments aim towards “sustainable” development both environmentally (safeguarding the shortage of resources such as land, energy, and natural elements), and socially (protecting the population and raising its level of well-being) according to so-called “ethical finance”, instead of a mere “speculative” investment. Effectively, real estate is still an investment sector only marginally explored by the socially-responsible funds. Based on these premises, this paper will: (i) briefly analyze the nature of socially-responsible investments, setting their characteristics apart from “traditional investments”; and (ii) propose a possible procedure (of the multi-criteria type) which aims to assess socially-responsible investments in real estate. This will be applied to a case study regarding a social housing initiative in the municipality of Anguillara Sabazia (Rome, Italy).
Comparison between Inverse Model and Chaos Time Series Inverse Model for Long-Term Prediction
Authors: Kim Young-Jin
Published: June 2017

This paper presents an inverse model using chaotic behaviour. The chaos time series inverse model, which uses coupling methods between an inverse model and chaos theory can reconstruct a deterministic and low-dimensional phase space by transforming irregular behaviours of nonlinear time-varying systems into a strange attractor (e.g., a Rossler attractor or a Lorenz attractor), and it can then predict future states. For this study, the author used a training dataset measured in an existing high-rise building and examined the predictive abilities of the chaos time series inverse model modelled into phase spaces with strange attractors in comparison with those of the Support Vector Regression (SVR) out of the inverse model. The paper discusses the effective use of the chaos time series inverse model for multi-step ahead prediction.
Measuring Spatial Distribution Characteristics of Heavy Metal Contaminations in a Network-Constrained Environment: A Case Study in River Network of Daye, China
Authors: Wang Zhensheng , Nie Ke
Published: June 2017

Measuring the spatial distribution of heavy metal contaminants is the basis of pollution evaluation and risk control. Considering the cost of soil sampling and analysis, spatial interpolation methods have been widely applied to estimate the heavy metal concentrations at unsampled locations. However, traditional spatial interpolation methods assume the sample sites can be located stochastically on a plane and the spatial association between sample locations is analyzed using Euclidean distances, which may lead to biased conclusions in some circumstances. This study aims to analyze the spatial distribution characteristics of copper and lead contamination in river sediments of Daye using network spatial analysis methods. The results demonstrate that network inverse distance weighted interpolation methods are more accurate than planar interpolation methods. Furthermore, the method named local indicators of network-constrained clusters based on local Moran’ I statistic (ILINCS) is applied to explore the local spatial patterns of copper and lead pollution in river sediments, which is helpful for identifying the contaminated areas and assessing heavy metal pollution of Daye.
Factors Affecting Hearing Aid Adoption and Use: A Qualitative Study
Authors: Gallagher Nicola E. , Woodside Jayne V.
Published: June 2017

Background:Despite a high prevalence of age-related hearing loss in older people, there is an unexplained low level of hearing aid adoption and use. Further research is required to determine the reason because hearing aids can vastly improve the quality of life for those with
hearing loss.Purpose:The aim of this study was to explore factors associated with hearing aid adoption and use, and to determine whether these differed between groups with different hearing aid use behaviors.Research Design:Individual face-to-face semistructured interviews.Study
Sample:Three groups of older people with hearing loss in Northern Ireland were recruited: (1) regular hearing aid users (n = 12), (2) irregular hearing aid users (n = 10), and (3) hearing aid nonowners (n = 10).Data Collection and Analysis:Qualitative thematic analysis, using principles
of grounded theory, was used to code the data and extract emerging themes for each of the three groups to distinguish similarities and differences between the groups. One-way analysis of variance and χ2 tests were used to determine the difference in continuous and categorical
variables, respectively, between the three groups.Results:Similar themes emerged across the three groups: the complexity of low hearing aid use and attitudes to hearing loss/hearing aid use. A third theme, inadequacy of audiology services, was identified in both groups using hearing
aids. Older age people having more severe hearing loss and longer duration of hearing aid ownership were associated with greater hearing aid adoption and use.Conclusions:Similar themes emerged from qualitative analysis across groups of people with hearing loss. More information for
those with hearing loss and those with hearing aids and scheduled follow-up appointments for those with hearing aids are essential to improve hearing aid adoption and use in older people. Further research should focus on the most suitable methods of distributing this information and how often
follow-up appointments should take place to achieve optimal hearing aid adoption and use.
An Explanation of Remarkable Emission-line Profiles in Post-flare Coronal Rain
Authors: Lacatus Daniela A. , Judge Philip G. , Donea Alina
Published: June 2017

We study broad redshifted emission in chromospheric and transition region lines that appears to correspond to a form of post-flare coronal rain. Profiles of Mg ii, C ii, and Si iv lines were obtained using IRIS before, during, and after the X2.1 flare of 2015 March 11 (SOL2015-03-11T16:22). We analyze the profiles of the five transitions of Mg ii (the

h and k transitions, and three lines belonging to the

transitions). We use analytical methods to understand the unusual profiles, together with higher-resolution observational data of similar phenomena observed by Jing et al. The peculiar line ratios indicate anisotropic emission from the strands that have cross-strand line center optical depths (k line) of between 1 and 10. The lines are broadened by unresolved Alfvénic motions whose energy exceeds the radiation losses in the Mg ii lines by an order of magnitude. The decay of the line widths is accompanied by a decay in the brightness, suggesting a causal connection. If the plasma is ≲99% ionized, ion–neutral collisions can account for the dissipation; otherwise, a dynamical process seems necessary. Our work implies that the motions are initiated during the impulsive phase, to be dissipated as radiation over a period of an hour, predominantly by strong chromospheric lines. The coronal “rain” we observe is far more turbulent than most earlier reports have indicated, with implications for plasma heating mechanisms.

Le facteur Chine dans la politique vietnamienne au début du mandat de Donald Trump
Authors: de Tréglodé Benoît
Published: June 2017

La diplomatie de la République Socialiste du Viêt Nam (RSVN) s’est peu positionnée depuis le début de la présidence de Donald Trump. Le Viêt Nam ne souhaite pas malmener ses liens avec Washington. Même en l’absence du TPP, les deux États ont une relation économique importante. Mais ce qui préoccupe surtout Hanoi réside dans l’attitude de Washington vis-à-vis de la mer de Chine méridionale. Fidèle à sa politique d’équilibre entre les grandes puissances, le Viêt Nam a toujours évalué la place des États-Unis en Asie-Pacifique à l’aune de l’avenir de sa relation avec Pékin. Face à la Chine, avec qui le Viêt Nam entretient une relation historique contrainte et compliquée ; il n’est toujours pas question de choisir entre Beijing et Washington. Le Viêt Nam, prudent, redoute avant tout les orientations trop inclusives de sa diplomatie multilatérale.
Gérer les risques permanents des bitcoins et des monnaies virtuelles de même type
Authors: Degos Jean-Guy
Published: June 2017

Les autorités monétaires et bancaires qui ont été pendant des siècles les tuteurs non acceptés des individus, représentant la puissance publique et sa coercition font l’objet d’un rejet souvent bien compréhensible. De nouvelles monnaies, ou pseudo-monnaies, fondées sur la cryptographie, sont apparues et se développent à l’aide de la technique des chaînes de blocs, avec des réseaux décentralisés de personnes actives ne souhaitant plus collaborer avec les banques. Quelles sont les promesses et les menaces de cette nouvelle approche pécuniaire ? Ses avantages compensent-ils ses risques ? C’est ce que nous allons tenter de préciser en combinant, approche diachronique, données d’enquêtes et recoupements multidimensionnels. Le principal résultat est que les monnaies virtuelles demeurent risquées et ne constituent pas un substitut définitif des faiblesses bancaires.

La synergie : concept utile ou fausse justification ?
Authors: Gintrac Alain
Published: June 2017

Lors de la plupart des opérations de fusion-acquisition le motif le plus souvent avancé est la synergie de sorte que cette justification pourrait être seulement un paravent. En effet, force est de reconnaître que la notion de synergie demande à être clarifiée et précisée. En définir les facteurs est insuffisants car la synergie génère aussi des coûts. A la suite de ces précisions, il sera possible d’apprécier objectivement l’utilité réelle de ce concept en dégageant une synergie potentielle ou ex ante et une synergie réelle ou ex post et de s’interroger sur les raisons de divergence de ces deux mesures. Finalement, on pourra constater que le concept de synergie est ainsi devenu plus opérationnel.
Frustration relative et individualisation des inégalités
Authors: Dubet François
Published: June 2017

La frustration relative est un schéma d’explication des conduites sociales trop général pour se suffire à lui-même. Il convient donc d’en évaluer la portée quand l’expérience des inégalités s’individualise et se diversifie lorsqu’on s’éloigne d’une structuration des inégalités en termes de classes sociales. Quels cadres de comparaison sont mobilisés, comment sont attribuées des causes aux injustices sociales, quels schémas moraux conduisent à agir ? Il n’est pas exclu que la rencontre de l’individualisation des inégalités et de la frustration relative explique aujourd’hui le développement des populismes.
Comment les Français jugent-ils leur statut social ?
Authors: Forsé Michel , Parodi Maxime
Published: June 2017

Au cours d’une enquête par sondage représentatif, il était demandé aux interviewés de se situer au sein de trois échelles de statuts (allant chaque fois de 1 à 10) en notant ce qu’ils considéreraient être leur position à la fin de leurs études, aujourd’hui, ainsi que celle qui serait juste selon eux. Il en ressort que plus la mobilité sociale est ressentie comme faible, plus l’écart entre le statut social jugé juste et celui d’aujourd’hui a tendance à être important. Cette attente d’une position juste plus élevée est d’autant plus forte que l’on s’estime bas dans la hiérarchie sociale. L’autoposition actuelle a d’ailleurs sur la frustration sociale un effet plus important que celui de la mobilité sociale. Si les catégories populaires ressentent davantage de frustration, c’est surtout en raison de l’inégalité des chances qu’elles dénoncent. Les enquêtés attendent donc plus d’égalité des chances mais aussi des places.
Estudio de la relación entre miembros del comité editorial de las revistas científicas de Psicología y su producción según diferentes indicadores bibliométricos
Authors: González-Sala Francisco , Osca-Lluch Julia
Published: June 2017

El objetivo del presente trabajo es estudiar la relación entre los miembros del comité editorial que publican artículos en revistas de las que forman parte y la propia revista. Los resultados apuntan que los miembros del comité editorial publican sus artículos de forma más rápida frente a los autores que no forman parte del comité, y que no existe colaboración entre los miembros con mayor presencia en diferentes comités, sí habiéndola entre miembros de una misma revista. En 6 de las 10 revistas estudiadas el porcentaje de artículos firmados por algún miembro del comité supera el 25%, y en tres de estas revistas el tiempo de publicación de estos artículos es significativamente inferior al tiempo de publicación de autores que no forman parte del comité. Se puede concluir que formar parte del comité editorial es una vía utilizada por los autores para publicar sus artículos de forma más rápida.

Evaluation of Mowing Frequency on Right-of-Way Plant Communities in Mississippi
Authors: Entsminger Edward D. , Jones Jeanne C. , Guyton John W. , Strickland Bronson K. , Leopold Bruce D.
Published: June 2017

Native grasses and native wildflowers are declining, especially along roadside right-of-ways because of intensive mowing and herbicide management practices. Roadside right-of-ways undergo regular disturbances such as mowing, maintenance, and road developments that affect soils, groundwater, surface hydrology, and vegetation composition. We investigated species richness and percent coverage within plant communities along highway right-of-ways to determine if reduced mowing increased native plant coverage. The study was conducted using 10 research plots situated along Highway 25 in Oktibbeha and Winston counties, Mississippi. Each research plot consisted of three different treatments as follows: one that included greater than four mowings per year, one mowing only in fall, and one mowing only in fall with a supplemental native wildflower seeding. Using line transect sampling, we detected 277 plant species, which included native and nonnative forbs, legumes, grasses, rushes, sedges, and woody perennials (vines, shrubs, and trees). Total percent coverage of native and nonnative plants within different growth form categories did not differ among treatments (F2,96 = 0.45, P = 0.83). However, coverage differed between uplands and lowlands (F1,96 = 18.22, P ≤ 0.001), between years (F1,96 = 14.54, P ≤ 0.001), between fall and spring seasons (F1,96 = 16.25, P ≤ 0.001), and interacted between years and seasons (F1,96 = 24.08, P ≤ 0.001) and seasons and elevations (F1,96 = 5.00, P ≤ 0.001). Nonnative agronomic grasses exhibited the greatest coverage (> 90%) in all treatments. Percent coverage of each plant growth form was greatest in lowlands. Our research showed an increase of native grasses and wildflower species along roadsides with a reduced mowing regimen. We concluded that the timing and intensity of mowing for the duration of our study had little effect on the species composition of plant communities. However, one mowing per year retained agronomic plant coverage for erosion control and soil stabilization during roadside maintenance. Specific proactive management implementations can include native plantings, selective herbicide use to decrease nonnative grasses, continual mowing from roadside edge to 10 m, and only one mowing in late fall, but with an extension of the boundary to reach beyond 10 m from the roadside edge to suppress the invasion of woody plants, which could lead to lower long-term maintenance costs.
Holiness in Victorian and Edwardian England: Some ecclesial patterns and theological requisitions
Authors: Goroncy Jason A.
Published: June 2017

This essay begins by offering some observations about how holiness was comprehended andexpressed in Victorian and Edwardian England. In addition to the ‘sensibility’ and ‘sentiment’that characterised society, notions of holiness were shaped by, and developed in reaction to, dominant philosophical movements; notably, the Enlightenment and Romanticism. It thenconsiders how these notions found varying religious expression in four Protestant traditions – he Oxford Movement, Calvinism, Wesleyanism, and the Early Keswick movement. Injuxtaposition to what was most often considered to be a negative expression of holinessassociated primarily with anthropocentric and anthroposocial behaviour as evidenced in thesetraditions, the essay concludes by examining one – namely, P.T. Forsyth – whose voice calledfrom within the ecclesial community for a radical requisition of holiness language as afundamentally positive reality describing the divine life and divine activity. The relevance of astudy of the Church’s understanding of holiness and how it sought to develop its doctrinewhile engaging with larger social and philosophical shifts endure with us still.

Latin America is among the highly endemic regions for cystic echinococcosis (CE). In Peru, an estimated 1,139 disability-adjusted life years are lost annually from surgical treatment of CE. This is comparable with the combined total for Argentina, Brazil, Uruguay, and Chile. The prevalence of human infection has been investigated in the central Peruvian Andes, but there are no community-based screening data from other regions of Peru. We carried out a population survey in January 2015 using abdominal ultrasound to estimate the prevalence of abdominal CE in the Canas and Canchis provinces, in the Cusco region of Peru. Among 1,351 subjects screened, 41 (3%) had CE. There was significant variation between communities with similar socioeconomic features in a small geographical area. A history of CE was reported by 4.1% of the screened subjects, among whom 30.3% still had CE on ultrasound. Among patients reporting previous CE treatment, 14.9% had CE in active stages. Limited education, community of residence, and knowing people with CE in the community were associated with CE. These results demonstrate a significant burden of CE in the region and suggest the need for further investigations, control activities, and optimization of clinical management for CE in this area.
Conflicted Heritage: Values, Visions and Practices in the Management and Preservation of Cultural and Environmental Heritage
Authors: Kearsley Geoffrey , Middleton Martine
Published: June 2017

Cultural heritage has become of great importance in a number of areas, including self-identity, community identity and as an economic sector through cultural tourism. Most definitions of heritage now accept that it is a perceptual construct with many meanings, both for those who identify and manage it and for those who consume it in various ways. Because heritage can be seen in many lights, the potential for conflict between users, managers and those who own heritage is high.

This article examines the nature of heritage and heritage landscapes and discusses the many symbolic and economic benefits that can ensue; the changing nature of the markets for heritage is described. The various monetary and opportunity costs of heritage are discussed and the resultant conflicts outlined. The article goes on to examine the contradictions and conflicts inherent in the concept of authenticity and the issues involved in various modes of interpretation. Here the article asks that if heritage is accepted as that which ‘we’ wish to preserve, then who are ‘we’?

This question is explored in the context of the impacts of tourism upon heritage in Southern New Zealand, including the impacts of recent development, perceptions of crowding and the nature of wilderness. Inter-cultural perceptions are explained through the differing perceptions of, and attitudes to, the natural world held by Maori and by others.

The article concludes by noting that, while much heritage research is still based upon the product and its presentation, future studies will need to learn more on consumers, their attitudes , expectations and values.
Many Bottles for Many Flies: Managing Conflict over Indigenous Peoples’ Cultural Heritage in Western Australia
Authors: Ritter David
Published: June 2017

This article critically considers the legal regulation of Indigenous people's cultural heritage in Western Australia and its operation within the framework of Australia's federal system of government. The article also sets out the different ways in which Indigenous cultural heritage is conceptualised, including as a public good analogous to property of the crown, an incidental right arising from group native title and as the subject of private contract. The article explores the various notions of 'Indigenous cultural heritage' that exist under Western Australian public law and the significant role of private contractual arrangements. Particular attention is devoted to the uneasy nexus between the laws of native title and heritage in Western Australia.
Belongings: Oral History, Objects and an Online Exhibition
Authors: Wilton Janis
Published: June 2017

The New South Wales Migration Heritage Centre was established in 1998. Since 2003 its physical presence has been located within Sydney’s Powerhouse Museum and it has had the strategic brief to record the memories of ageing migrants before their stories are lost. The Centre is, however, a museum without a collection; a heritage authority without heritage sites; a cultural institution whose main presence is in cyberspace. Among its high profile projects is one entitled Objects through time and another Belongings. Both focus on the ways in which objects can convey aspects of the migration experience. Belongings, the focus of this article, presents the remembered experiences of people who migrated to Australia after World War II, and seeks to highlight significant features of their experiences through asking them to share their memories and to nominate and talk about significant objects. As a project it grew out of movable heritage policy work within state government agencies, and its initiators – John Petersen, Kylie Winkworth and Meredith Walker – were central players in this development. It was also inspired by the National Quilt Register of the Pioneer Women’s Hut at Tumbarumba.

With its object-centred approach and accompanying edited interview transcripts, Belongings provides a focus for exploring the messages and emphases that emerge when oral history interviews concerned with migration have the specific brief to ask about material culture and its significance. Belongings also enables an exploration of the layering of those messages that emerges when object captions are located back in the context of the oral history interviews from which they were extracted. As a virtual exhibition, Belongings also provides the opportunity to consider the challenges for museums (virtual and real) when they need to condense the richness of migrant oral histories and life stories to captioned objects that can be put on display.
There is no ‘I’ in Team: Reflections on Team-Based Content Development at the National Museum of Australia
Authors: Hansen Guy
Published: June 2017

In recent years one of the most important trends in the development of history exhibitions in major museums has been the use of interdisciplinary project teams for content development. This approach, often referred to as the team based model of content development, has, in many institutions, replaced older models of exhibition production built around the expertise of the curator. The implementation of team based models has had a profound impact on the way exhibitions are produced. When done well it has helped deliver exhibitions combining a strong focus on audience needs with in-depth scholarship and collections research. In some contexts, however, the tyranny of the team has given rise to a form of museological trench warfare in which different stakeholders struggle for creative control of an exhibition. In this article I will explore some aspects of the team based approach with reference to the development of the opening suite of exhibitions for the National Museum of Australia (NMA) in 2001. My observations are drawn from my experience as the lead curator of the Nation Gallery, one of the NMA’s opening exhibitions.
Sydney's Past, History's Future: The Dictionary of Sydney
Authors: Murray Lisa , Grahame Emma
Published: June 2017

The Dictionary of Sydney www.dictionaryofsydney.org is a ground breaking, multimedia city biography that can present the history of metropolitan Sydney on the web, in your hand and on the street. Through its historical model the digital repository allows historical elements to be classified, connected, geo-referenced and mapped through space and time. By combining the fine-grained with the global, the histories in the Dictionary mirror the experience of the metropolis – the intimate and the personal interact with the impersonal and indeed often random nature of city life. A purely digital history redefines the possibilities for urban history and public history. This paper will introduce the Dictionary of Sydney, share some of the challenges and joys of building a digital history, and reflect upon the ways digital history as a publication form is shaping and changing the practice of public history.
