With a complex etiology involving multiple factors, the condition known as itch is a primary symptom of many skin diseases. Current treatment methods are ineffective for addressing itches caused by dry skin, for example. We developed a botanical extract, ACTPER, made from a mixture of Actinidia arguta and Perilla frutescens, which have traditionally been used to treat itch. The quality of ACTPER as a research agent was controlled in our experiment by cell-based bioassays, as well as by high-performance liquid chromatography (HPLC), using two chemical markers. In the acetone-induced dry skin mice model, the oral administration of ACTPER alleviated dry skin-related skin properties and itching behavior. The RNA and protein expression of the filament aggregating protein (filaggrin) gene, a key factor involved in the regulation of skin barrier function, was significantly increased, as measured by quantitative reverse transcription polymerase chain reaction (RT-PCR) and immunofluorescence assay. To understand the underlying mechanism(s) at the molecular level, HaCaT cells, a human keratinocyte-derived cell line, were treated with various concentrations of ACTPER. We found that the protein expression of filaggrin was indeed upregulated by ACTPER in a dose dependent manner. Data from experiments involving the reporter plasmid containing the xenobiotic response element (XRE), and the chemical antagonist for the aryl hydrocarbon receptor (AhR), indicated that the ACTPER-mediated upregulation of filaggrin was controlled through the activation of the AhR signaling pathway. The molecular docking simulation study predicted that ACTPER might contain chemical compounds that bind directly to AhR. Taken together, our results suggest that ACTPER may provide the platform, based upon which a variety of safe and effective therapeutic agents can be developed to treat itch.

Published: June 2019

Folate, vitamin B2, vitamin B6, vitamin B12, choline, and betaine are nutrients involved in the 1-carbon cycle that can alter the levels of DNA methylation and influence genesis and/or tumor progression. Thus, the objective of this study was to evaluate the association of folate and vitamins involved in the 1-carbon cycle and MTHFR polymorphisms in global DNA methylation in patients with colorectal cancer gene. The study included 189 patients with colorectal adenocarcinoma answering a clinical evaluation questionnaire and the Food Frequency Questionnaire (FFQ) validated for patients with colon and rectal cancer. Blood samples were collected for evaluation of MTHFR gene polymorphisms in global DNA methylation in blood and in tumor. The values for serum folate were positively correlated with the equivalent total dietary folate (total DFE) (rho = 0.51, p = 0.03) and global DNA methylation (rho = 0.20, p = 0.03). Individuals aged over 61 years (p = 0.01) in clinicopathological staging III and IV (p = 0.01) and with + heterozygous mutated homozygous genotypes for the MTHFR A1298C gene had higher levels of global DNA methylation (p = 0.04). The association between dietary intake of folate, serum folate, and tumor stage were predictive of global DNA methylation in patients’ blood. The levels of serum folate, the dietary folate and the status of DNA methylation can influence clinicopathological staging.
Comparison of the Effectiveness of Lifestyle Modification with Other Treatments on the Incidence of Type 2 Diabetes in People at High Risk: A Network Meta-Analysis
Authors: Yamaoka Kazue , Nemoto Asuka , Tango Toshiro
Published: June 2019

Background: Many clinical trials have been conducted to verify the effects of interventions for prevention of type 2 diabetes (T2D) using different treatments and outcomes. The aim of this study was to compare the effectiveness of lifestyle modifications (LM) with other treatments in persons at high risk of T2D by a network meta-analysis (NMA). Methods: Searches were performed of PUBMED up to January 2018 to identify randomized controlled trials. The odds ratio (OR) with onset of T2D at 1 year in the intervention group (LM, dietary, exercise, or medication) versus a control group (standard treatments or placebo) were the effect sizes. Frequentist and Bayesian NMAs were conducted. Results: Forty-seven interventions and 12 treatments (20,113 participants) were used for the analyses. The OR in the LM was approximately 0.46 (95% CI: 0.33 to 0.61) times lower compared to the standard intervention by the Bayesian approach. The effects of LM compared to other treatments by indirect comparisons were not significant. Conclusions: This meta-analysis further strengthened the evidence that LM reduces the onset of T2D compared to standard and placebo interventions and appears to be at least as effective as nine other treatments in preventing T2D.

Published: June 2019

Yak-Kong (YK), a small black soybean (Glycine max) in Korea, contained higher concentrations of antioxidants than ordinary black soybean or yellow soybean in our previous study. We prepared the fermented YK extract by using a novel lactic acid bacterium, Pediococcus pentosaceus AOA2017 (AOA2017) isolated from Eleusine coracana, and found that the antioxidant ability was enhanced after fermentation. In order to investigate the cause of the enhanced antioxidant ability in the fermented YK extract, we conducted a phenolic composition analysis. The results show that proanthocyanidin decreased and phenolic acids increased with a statistical significance after fermentation. Among the phenolic acids, p-coumaric acid was newly produced at about 11.7 mg/100 g, which did not exist before the fermentation. Further, the fermented YK extract with increased p-coumaric acid significantly inhibited the lipopolysaccharide-induced THP-1 monocyte–endothelial cell adhesion compared to the unfermented YK extract. The fermented YK extract also suppressed the protein expression levels of vascular cell adhesion molecule (VCAM)-1 in human umbilical vein endothelial cells (HUVECs). Together with the previous studies, our results suggest that the extract of YK fermented by AOA2017 has potential to be a new functional food material with its enhanced bioactive compounds which may help to prevent atherosclerosis caused by oxidative stress.

Authors: Wan Khalid Wan Elina Faradilla , Mat Arip Mohamad Nasir , Jasmani Latifah , Lee Yook Heng
Published: June 2019

A new cellulose nanocrystal–reduced graphene oxide (CNC–rGO) nanocomposite was successfully used for mediatorless electrochemical sensing of methyl paraben (MP). Fourier-transform infrared spectroscopy (FTIR) and field-emission scanning electron microscopy (FESEM) studies confirmed the formation of the CNC–rGO nanocomposite. Cyclic voltammetry (CV) studies of the nanocomposite showed quasi-reversible redox behavior. Differential pulse voltammetry (DPV) was employed for the sensor optimization. Under optimized conditions, the sensor demonstrated a linear calibration curve in the range of 2 × 10−4–9 × 10−4 M with a limit of detection (LOD) of 1 × 10−4 M. The MP sensor showed good reproducibility with a relative standard deviation (RSD) of about 8.20%. The sensor also exhibited good stability and repeatability toward MP determinations. Analysis of MP in cream samples showed recovery percentages between 83% and 106%. Advantages of this sensor are the possibility for the determination of higher concentrations of MP when compared with most other reported sensors for MP. The CNC–rGO nanocomposite-based sensor also depicted good reproducibility and reusability compared to the rGO-based sensor. Furthermore, the CNC–rGO nanocomposite sensor showed good selectivity toward MP with little interference from easily oxidizable species such as ascorbic acid.
Optimized PID Controller Based on Beetle Antennae Search Algorithm for Electro-Hydraulic Position Servo Control System
Authors: Fan Yuqi , Shao Junpeng , Sun Guitao
Published: June 2019

To improve the controllability of an electro-hydraulic position servo control system while simultaneously enhancing the anti-jamming ability of a PID controller, a compound PID controller that combines the beetle antennae search algorithm with PID strategy was proposed, and used to drive the position servo control system of the electro-hydraulic servo system. A BAS-PID controller was designed, and the beetle antennae search algorithm was used to tune PID parameters so that the disturbance signal of the system was effectively restrained. Initially, the basic mathematical model of the electro-hydraulic position servo control system was established through theoretical analysis. The transfer function model was obtained by identifying system parameters. Then, the PID parameter-tuning problem was converted into a class of three-dimensional parameter optimization problem, and gains of PID controllers were adjusted using the beetle antennae search algorithm. Finally, by comparing the effectiveness of different algorithms, simulation and experimental results revealed that the BAS-PID controller can greatly enhance the performance of the electro-hydraulic position servo control system and inhibit external disturbances when different interference signals are used to test the system’s robustness.
A Binder Jet Printed, Stainless Steel Preconcentrator as an In-Line Injector of Volatile Organic Compounds

Published: June 2019

A conventional approach to making miniature or microscale gas chromatography (GC) components relies on silicon as a base material and MEMS fabrication as manufacturing processes. However, these devices often fail in medium-to-high temperature applications due to a lack of robust fluidic interconnects and a high-yield bonding process. This paper explores the feasibility of using metal additive manufacturing (AM), which is also known as metal 3D printing, as an alternative platform to produce small-scale microfluidic devices that can operate at a temperature higher than that which polymers can withstand. Binder jet printing (BJP), one of the metal AM processes, was utilized to make stainless steel (SS) preconcentrators (PCs) with submillimeter internal features. PCs can increase the concentration of gaseous analytes or serve as an inline injector for GC or gas sensor applications. Normally, parts printed by BJP are highly porous and thus often infiltrated with low melting point metal. By adding to SS316 powder sintering additives such as boron nitride (BN), which reduces the liquidus line temperature, we produce near full-density SS PCs at sintering temperatures much lower than the SS melting temperature, and importantly without any measurable shape distortion. Conversely, the SS PC without BN remains porous after the sintering process and unsuitable for fluidic applications. Since the SS parts, unlike Si, are compatible with machining, they can be modified to work with commercial compression fitting. The PC structures as well as the connection with the fitting are leak-free with relatively high operating pressures. A flexible membrane heater along with a resistance-temperature detector is integrated with the SS PCs for thermal desorption. The proof-of-concept experiment demonstrates that the SS PC can preconcentrate and inject 0.6% headspace toluene to enhance the detector’s response.
A Highly Robust Silicon Ultraviolet Selective Radiation Sensor Using Differential Spectral Response Method
Authors: Sipauba Carvalho da Silva Yhang Ricardo , Kuroda Rihito , Sugawa Shigetoshi
Published: June 2019

This paper presents a silicon ultraviolet radiation sensor with over 90% UV internal quantum efficiency (QE) and high selectivity to the UV waveband without using optical filters. The sensor was developed for applications that require UV measurement under strong background visible and near-infrared (NIR) lights, such as solar UV measurement, UV-C monitoring in greenhouses or automated factories, and so on. The developed sensor is composed of monolithically formed silicon photodiodes with different spectral sensitivities: a highly UV responsive photodiode with internal quantum efficiency (QE) of nearly 100% for UV light, and a lowly UV responsive photodiode with UV internal QE lower than 10%. The photodiodes were optimized to match their visible and NIR light responsivity, and the UV signal is extracted from the background radiation by using the differential spectral response method. With this approach, an internal QE of over 90% for UV light was obtained, with a residual internal QE to non-UV light lower than 20% for 400 nm, 5% for 500 nm, 2% for 600 nm and 0.6% to NIR light. The developed sensor showed no responsivity degradation after exposure towards strong UV light. It was confirmed by the simulation results that the residual responsivity is further suppressed by employing an on-chip band-rejection optical layer consisting of several layers of silicon oxide and silicon nitride films.
Handheld Microflow Cytometer Based on a Motorized Smart Pipette, a Microfluidic Cell Concentrator, and a Miniaturized Fluorescence Microscope
Authors: Kim Byeongyeon , Kang Dayoung , Choi Sungyoung
Published: June 2019

Miniaturizing flow cytometry requires a comprehensive approach to redesigning the conventional fluidic and optical systems to have a small footprint and simple usage and to enable rapid cell analysis. Microfluidic methods have addressed some challenges in limiting the realization of microflow cytometry, but most microfluidics-based flow cytometry techniques still rely on bulky equipment (e.g., high-precision syringe pumps and bench-top microscopes). Here, we describe a comprehensive approach that achieves high-throughput white blood cell (WBC) counting in a portable and handheld manner, thereby allowing the complete miniaturization of flow cytometry. Our approach integrates three major components: a motorized smart pipette for accurate volume metering and controllable liquid pumping, a microfluidic cell concentrator for target cell enrichment, and a miniaturized fluorescence microscope for portable flow cytometric analysis. We first validated the capability of each component by precisely metering various fluid samples and controlling flow rates in a range from 219.5 to 840.5 μL/min, achieving high sample-volume reduction via on-chip WBC enrichment, and successfully counting single WBCs flowing through a region of interrogation. We synergistically combined the three major components to create a handheld, integrated microflow cytometer and operated it with a simple protocol of drawing up a blood sample via pipetting and injecting the sample into the microfluidic concentrator by powering the motorized smart pipette. We then demonstrated the utility of the microflow cytometer as a quality control means for leukoreduced blood products, quantitatively analyzing residual WBCs (rWBCs) in blood samples present at concentrations as low as 0.1 rWBCs/μL. These portable, controllable, high-throughput, and quantitative microflow cytometric technologies provide promising ways of miniaturizing flow cytometry.
Prospects of Public Participation in the Planning and Management of Urban Green Spaces in Lahore: A Discourse Analysis
Authors: Alam Rizwana , Lovett Jon C.
Published: June 2019

Green spaces in cities are under pressure from increasing population, urbanization, and development, making governance of these common pool resources a complex and multi-dimensional process. Governance of urban green spaces can be improved by participatory approaches. However, many developing countries do not have the institutional structures and policies that promote the participation of a range of non-state actors, and green spaces are often removed from public access by regulatory slippage or elite capture for parks and gardens. This paper uses discourse analysis to explore the perspectives of the key stakeholders for public participation in the planning and management of green spaces in Lahore. The study employs Q-methodology to reveal four discourses: ‘Efficient Management’, ‘Anti/Pro-Administrative’, ‘Leadership and Capacity building’, and ‘Decentralization or Elite capture’. The most significant and dominant discourse of ‘Efficient Management’ shows stakeholders’ preferences towards developing new institutional arrangements at the local level through engaging citizens. The two discourses ‘Leadership and Capacity building’ and ‘decentralization or elite capture’ are also in favor of changing the power dynamics in the system at certain levels by using different strategies. However, the status quo-oriented administrative discourse serves as a barrier, resisting change at any level. The results of this study suggest a need for policy reforms to develop a conducive environment in which all the stakeholders can be engaged through different collaborative and co-management schemes, in order to achieve economically efficient, ecologically sustainable and socially equitable, urban green spaces in Lahore.
Circular Economy and Resilience Thinking for Historic Urban Landscape Regeneration: The Case of Torre Annunziata, Naples
Authors: Fabbricatti Katia , Biancamano Paolo Franco
Published: June 2019

The landscape, as an archive of the traces of the history of man and nature, can be considered a holistic indicator of sustainable, inclusive, safe, resilient cities as set out in Agenda 2030 for Sustainable Development. The UNESCO Recommendations on Historic Urban Landscape (HUL) reflect it as a dynamic/evolving system that changes over time to meet social needs: it requires to be managed in a sustainable way, not only as a resource to be preserved. The beauty of the landscape is a common element in the development policies of many small-medium European and Italian cities. However, the state of abandonment and decay, the lack of investments, of often emigrated skills are the detractors. The circular economy model applied to the HUL leads to the ability to maximize the value of settlements, activating social, economic and environmental synergies. The research identifies the relationship among Circularity, Productivity and Resilience as an effective key to achieve the goals of Agenda 2030. The methodological approach tested on the case study of Torre Annunziata, Naples has reached a system of resilience performance indicators to express the complex nature of HUL and define a scenario of circular regeneration, based on the recreation of a virtuous circuit between physical, environmental, social, economic systems.

Published: June 2019

The article deals with a unique monument of history and culture, dating back to the era of classicism and playing an important role in the historical context and architectural ensemble of Moscow. The restoration processes of facades and interiors in 2013-2016 of the Academic Maly Theater of Russia, which is an object of cultural heritage of federal significance, are studied. The history of construction, the problems of uneven precipitation of the building and its stabilization are considered. In the process of restoration work, within the framework of supervision, scientific and methodological guidance, there is an opportunity for additional research, which in turn allows recreating a single artistic ensemble of the theater's interiors belonging to the so-called "red zone". The issues of recreating the author's coloristic solution of the auditorium, the painting of the ceiling and the auditorium border are reviewed in detail. They are the dominant of interior with unique features and undoubted monument of decorative and applied art of the middle of the XX century. In the process of repair works, the overall coloristic style of the premises has changed to simplification. Apparently, this is due to the fact that repair works were carried out by economic services, often without attaching importance to the coloristic nuances. The significance of interdisciplinary approach in restoration is emphasized.
Analysis of the main parameters of spring and summer food compound of roe deer (Capreolus capreolus L.) on the two hunting grounds of the Alföld plain
Authors: Tamás Barta  , István Majzinger
Published: June 2019

It is widespread that roe deer are very choosy. It needs this sorting because the micro organisms, which help the digestion of high fibre plants, are missing in its stomach that is why they are mostly called „concentrate selectors” (Hoffmann, 1985, 1988, 1989).These animals should mostly eat easily digestible plants with high nutrition level (pulses, buds, sprouts and flowers), and they are able to do this sorting because of their small mouth size. In winter there is a lack of these plants, so the high selectivity occurs only when the feed is in abundance.Examining the amount and quality of vegetation available on the habitat of roe deer we can identify the species which can satisfy their feed demand. It is known, that roe deer as other large ruminants, from the plant abundance prefer certain plants and plant parts while there are others which are avoided. The identification of the eaten species and the rate of their occurrence in the feed is the first step to become acquainted with theinteraction between animal and the surroundings.

Leaf rust is one of the most significant fungal disease of wheat not only in Hungary but also in other parts of the world. For improving leaf rust resistance of winter wheat variety (Hajdúság, 2003) produced by conventional breeding methods, verified by results of variety tests, showing outstanding results in the aspect of the most important economic values, integration of tissue culture technics, genetic engineering and traditionalmethods may provide facilities. Building the gene(s) responsible for resistance into the determined genome can improve the resistance in a way that changes other features of the plant slightly or not at all. In the course of genetical transformation of the variety Hajdúság we applied one of the wheat’s own effecient green-tissue specific insurer genetical regulator, the promoter of ribulose carboxylase 1-5 bisphosphate (RuBisCo) ‘s smallsubunit to control the expression of the gene cmg1.
The channels in Storebælt, Denmark: implications of new radiocarbon ages
Authors: Bennike Ole , Nørgaard-Pedersen Niels , Jensen Jørn Bo
Published: June 2019

The brackish water Baltic Sea and the more saline Kattegat in the north are connected by three straits, Lillebælt, Storebælt and Øresund. Storebælt (the Great Belt) is the deepest and widest of the straits. The strait is characterised by deeply incised channels that are partly filled by sediments. The water depth in major parts of Storebælt is about 20 m, though in some areas the channels are more than 50 m deep.

The formation of the channels has been subject to discussion. Andersen (1927) suggested that the channels formed due to strong currents that are still active today or by fluvial erosion during the so-called continental period (Fastlandstiden) in the Early Holocene. At this time, the relative sea level in the region was lower than at present and a huge lake, the Ancylus Lake, which occupied the Baltic Basin, may have drained via Storebælt. Andersen dismissed the idea that the channels were formed by subglacial erosion by meltwater during the last deglaciation. More Recently, Mathiassen (1997) interpreted some of the deposits in the channels as late glacial, a viewpoint followed by Bennike et al. (2004). However, the age of the late glacial deposits in the channels are poorly constrained.

The first studies of sediment cores from Storebælt were carried out by Krog (1973), Winn (1974) and Mathiassen (1997), but these studies concentrated on the Holocene development from mires to lakes to brackish and marine environments. Wiberg-Larsen et al. (2001) documented the presence of Early Holocene river deposits. Here we report on some new ages of macrofossils from late glacial deposits in the Storebælt channels.

In the context of globalization today, speaking and using two languages is an advantage to develop yourself and to achieve success. To meet that need, many bilingual dictionaries were developed on a large scale. The bilingual Vietnamese-Khmer, Khmer-Vietnamese dictionary is still very modest in terms of number of  words. This has not satisfied the need to study bilingual Khmer - Vietnamese of the large population in Cambodia as well as people in areas with large Khmer  ethnic groups such as the Southwest. The bilingual dictionary of Vietnamese - Khmer and Khmer - Vietnamese  of Tra Vinh University will be a contribution to the development of the dictionary field, it will effectively support for learning bilingual Khmer - Vietnamese simultaneously. Contributing to preserving and promoting the national cultural identity and performing the political cooperation between Vietnam and Cambodia.

Environmental aspects of impacts of the impurities in the industrial microsilica during its processing
Authors: Evgenii Andreevich Mamchenkov , Valerii IUrevich Prokofev , Sergei Pavlovich Kochetkov
Published: June 2019

The mechanism of inhibitory effects of microsilica impurities on microsilica dissolution was discovered. The relevance of the work is due to the demand for liquid glass in the enterprises of Central Russia and the lower cost of raw materials, namely sodium silicate, compared with analogues. Waste disposal helps to solve the problems of resource conservation and environmental management. Microslica was studied by differential thermal analysis using a TGA 2 in the temperature range of 20...800 °C with a heating rate of 20 °C/min in air. Modification of microsilica was carried out by mixing with sodium hydroxide with a concentration of 15...25 wt.% at a temperature 20...50 °C with stirring at 600 rpm. The mechanism of formation of by-products with the basis of the obtained data was determined. The greatest contribution to the inhibitory effect on the process of producing liquid glass is made by aluminum ions. The resulting byproduct, hydroalumination sodium is formed in several stages and is catalyzed by sodium silicate. The reduction in the rate of mass transfer and temperature in the modification process of the microsilica reduces the amount of produced byproducts. The mechanism of inhibition of the process of dissolution of microsilica, a byproduct of the production of aluminum fluoride, was determined. The mechanism of the formation byproducts was proposed. The activation energy of the polymerization reaction was obtained. The value of the activation energy is 7.73 kJ/mol, indicates that the synthesis process takes place in the diffuse region. The optimal parameters of physical and chemical modification are determined. Microilica is treated with sodium hydroxide with a concentration of 25 % at a temperature of 20 °C at a speed of 600 rpm.

Authors: Fan X.L. , Bezerra J.D.P. , Tian C.M. , Crous P.W.
Published: June 2019

Members of the genus Cytospora are often reported as endophytes, saprobes or phytopathogens, primarily causing canker diseases of woody host plants. They occur on a wide range of hosts and have a worldwide distribution. Although several species have in the past been reported
from China, the vast majority are not known from culture or DNA phylogeny. The primary aim of the present study was thus to clarify the taxonomy and phylogeny of a large collection of Cytospora species associated with diverse hosts in China. Cytospora spp. were collected in northeast,
northwest, north and southwest China, indicating that the cold and dry environments favour these fungi. In this paper, we provide an assessment of 52 Cytospora spp. in China, focussing on 40 species represented by 88 isolates from 28 host genera. Based on a combination of morphology
and a six-locus phylogeny (ITS, LSU, act1, rpb2, tef1-α and tub2), 13 new species and one new combination are introduced. The majority of the species investigated here appear to be host-specific, although further collections and pathogenicity studies will
be required to confirm this conclusion.

Published: June 2019

BACKGROUND: An Arteriovenous fistula (AVF) is a creation of the natural blood vessels. It is a “gate of life” for the patients on hemodialysis. AIM: The study aimed to analyze the predictors for primary failure of AVF such as gender, age, number and location of AVF, and primary renal disease in patients with chronic kidney disease (CKD) stage 4/5.MATERIAL AND METHODS: The medical records of 178 created arteriovenous fistulae in patients with CKD stage 4/5, were retrospectively studied. Primary failure of AVF was defined as thrombosis or inability for cannulation of AVF within 3 months. Adequate maturation of AVF was defined as successful cannulation of AVF treatment and blood flow of > 600 ml/min.RESULTS: The mean age of the patients was 59.75 ± 14.65 years, and 65.16% (116/178) were men. Adequate maturation of AVF was achieved in 83.71% (149/178). Primary failure of AVF occurred in 16.29% (29/178) of the created fistulae, while 10.11% (18/178) had early thrombosis. The distal arteriovenous fistulae were significantly more frequently created in male patients (51 vs 18; p = 0.015). The female patients were significantly older than the male patients (63.27 vs 57.86 years; p = 0.018). CONCLUSION: Male gender was associated with better maturation of AVF. The age, number and location of AVF, and primary renal disease in patients with CKD stage 4/5 were not associated with primary failure of AVF.

Vieillissement en ville et villes en vieillissement
Authors: Buhnik Sophie
Published: June 2019

Le vieillissement transforme la physionomie des villes et des sociétés contemporaines ; il ne reçoit pourtant pas l’écho scientifique et médiatique accordé à d’autres transitions (comme le réchauffement climatique ou la transition numérique). Partant du constat d’un déficit de recherche théorique sur les interactions entre vieillissement et production urbaine, cet article rappelle d’abord le caractère multidimensionnel des relations entre ville et vieillissement. La complexité de ces interactions est liée d’une part à la pluralisation des expériences individuelles de l’avancée en âge, d’autre part à une diversification des territoires où la part des seniors augmente. En s’appuyant sur des recherches critiques envers la promotion du « vieillissement actif » dans les politiques publiques, nous montrons ensuite comment un fort taux de vieillissement met les collectivités territoriales aux prises, non seulement avec des besoins d’adaptation des tissus bâtis, mais encore avec un problème de continuité résidentielle. En effet, assurer l’accès des habitants âgés à des ressources de proximité suppose un dynamisme intergénérationnel à l’échelle des quartiers. Or c’est justement dans les parcs immobiliers où les occupants sont en majorité des propriétaires âgés, que cette condition s’avère la plus difficile à remplir.
Contexte, hors-texte, arrière-texte : à propos de l’ambivalence des notions en théorie littéraire
Authors: Trouvé Alain
Published: June 2019

Contexte , hors-texte et arrière-texte ont en commun de s’accorder à un référent linguistique et extra-linguistique. C’est peut-être parce qu’il y a du hors-texte au sens de hors langage qu’il y a de la littérature et c’est cette ambivalence qu’explorent le contexte et l’arrière-texte. Si les deux notions soulignent l’ancrage physique et circonstanciel de la relation littéraire, l’arrière-texte prend en outre en charge la dynamique créative d’un sujet coopérant avec son inconscient.
En dépit du contexte : le Bien, le Beau et le Signifiant
Authors: Poirier Jacques
Published: June 2019

Si la notion de contexte fait question, c’est qu’elle engage des enjeux philosophiques (le sujet n’existe-t-il qu’en situation ?), éthiques (un acte doit-il être apprécié à l’aune des circonstances ?) et esthétiques. Or, le paradoxe de l’œuvre d’art est que, née d’un milieu et d’un moment donnés, elle peut traverser le temps et l’espace. Et bien que le sens des œuvres anciennes se dérobe à nous, elles continuent de nous toucher, comme si la beauté s’enlevait sur fond de contresens.
Le « contexte », un intrus dans l’histoire littéraire
Authors: Vaillant Alain
Published: June 2019

La question « qu’est-ce qu’un contexte ? » en appelle aussitôt une autre : « qu’est-ce qu’un texte ? », qui contredit la première : si le « contexte » invite à une historicisation des pratiques littéraires, la notion de « texte », dans son principe même, déloge la littérature du terrain historique qui devrait être le sien. De cette contradiction, généralement inaperçue, découlent les piétinements d’une histoire littéraire qui se contenterait de se penser comme une contextualisation plus ou moins idéologique, érudite ou sociologique des textes. Pour éviter cette aporie théorique, il suffit de renoncer aux notions de texte et de contexte pour privilégier la notion fondamentale de communication littéraire, puis de substituer à l’histoire des contextes littéraires une poétique historique des pratiques et des formes de l’écriture qui, sur la longue durée des sociétés humaines, doit mener à une anthropologie historique de la littérature.
Texte et contexte en génétique : peut-on parler de remploi et de récupération ?
Authors: Jeannelle Jean-Louis
Published: June 2019

Il est un phénomène de reprise textuel que la poétique et la génétique peinent à désigner lorsqu’un écrivain l’applique à ses propres manuscrits ou à ses propres textes. Nous proposons ici les notions de « remploi » et de « récupération » dont nous verrons qu’elles ont pour effet d’accentuer la fragilisation de l’autorité des textes ainsi que leur rapport au contexte. Sera pris pour exemple un cas d’engendrement textuel singulier, tiré d’un projet de roman d’André Malraux consacré à la Résistance («  Non  ») : celui-ci pose d’importants problèmes d’identification qui mettent en lumière cette dissolution de l’idée même de contexte, privé en grande partie de sa pertinence dans l’interprétation du manuscrit et de ses reprises au sein de l’œuvre publiée.

Épistémologie et méthode d’une sociologie des objets
Authors: Fouillet Aurélien
Published: June 2019

Les objets sont partout et tendent à se substituer à l’homme à tel point que la société des hommes est remplacée par celle des objets. La sociologie devrait alors s’intéresser à redéfinir une partie de son champ de recherche et intégrer la question de la société des objets comme objet d’étude. Cet article a pour vocation à poser les bases d’une recherche épistémologique et méthodologique à destination d’une recherche conjointe entre la sociologie et le design.
L’objet de design exposé : reconfiguration de l’expérience du quotidien
Authors: Kamoun Emna
Published: June 2019

Au-delà de l’opposition entre les objets d’art et ceux d’usage, l’objet de design a cette particularité de cultiver un statut ambivalent. Pour tenter de mieux le cerner, nous nous intéressons au vécu avec lui, et ce dans différents contextes. À travers une observation de l’objet de design mis en scène dans un cadre d’exposition évènementielle, nous tenterons de mettre en lumière le processus de construction de dimensions symbolique supplémentaires. Plus précisément, nous avons pour objectif d’explorer la tension résultante de l’opposition de sa contextualisation spatiale entre l’évènementiel et le quotidien. Comment cela reconfigure-t-il l’imaginaire et quel impact pourrait-il avoir sur l’expérience du quotidien ? La transposition du trope visuel au trope expérientiel constituera notre outil méthodologique principal pour expliquer ce mécanisme.
De la rente immobilière à la finance
Authors: Bonneval Loïc , Robert François
Published: June 2019

Doyenne des sociétés immobilières du Second Empire (antérieure même aux sociétés parisiennes), la Société de la rue Impériale (SRI) offre la possibilité de restituer plus de 150 ans de gestion immobilière d’un bâti « haussmannien » dans la principale artère d’une grande ville, Lyon. De sa création (1854) à sa disparition (2004), la SRI n’a cessé de placer la gestion des immeubles au centre de ses activités. Cette longévité exceptionnelle tranche avec les durées éphémères des sociétés immobilières nées dans la foulée des politiques de grands travaux au XIXe siècle. Tout au long de son existence, la détention d'un patrimoine immobilier d'exception lui a assuré une rente sur laquelle elle a assis son expansion. Elle bascule progressivement dans une logique financière à la fin des années 1960 à la suite d’une prise de contrôle par le milieu bancaire des grosses sociétés immobilières. Le rachat de la SRI par le fonds souverain d’Abu Dhabi achève le processus de financiarisation d’une des pièces les plus prestigieuses de l’immobilier lyonnais. Nourrie par des archives exceptionnelles, l’histoire de cette société immobilière permet de retracer, dans le temps long, les transformations des espaces urbains et de mieux comprendre le rôle du capital financier dans la production de la ville. Elle constitue de ce fait une approche originale de l’imbrication de l’économique et de l’urbain.
O Epítome Heidelberg: limites e possibilidades de uma fonte histórica do século XV
Authors: Modanez de Sant Anna Henrique
Published: June 2019

Este artigo apresenta uma discussão historiográfica sobre a fonte histórica conhecida como Epítome Heidelberg (FGH 155), um documento grego do século XV de autoria disputada e que trata dos primórdios do período helenístico (323-316 a.C.). Propõe especialmente avançar no debate a partir da tese de Pat Wheatley ao inserir o documento em epígrafe em uma breve discussão conceitual e metodológica sobre epítomes e fragmentos na historiografia grega.
