Published: March 2020

A aplicação da tecnologia é utilizada cada vez mais no setor agrícola, hoje em dia estão sendo empregados muitos estudos tencionando o manejo e ampliar a produtividade das culturas. A proposta deste projeto foi de pesquisar e compreender os conceitos de irrigação localizada automatizada, plataforma arduino e o emprego de sensores para a fiscalização de grandezas físicas. Com o intuito de unificar os conceitos estudados e criar um protótipo de um sistema de irrigação localizado automatizado usando as três tecnologias, conseguindo assim arquitetar um produto de baixo custo, preciso e acessível. Hoje no Brasil existem várias tecnologias disponíveis apontada para a agricultura, apesar disso são tecnologias de alto custo que precisam de grande investimento fazendo com que agricultores de pequeno e médio porte não possuam total aquisição a essas novas maneiras de trabalho. Atualmente a irrigação vem sendo uma das tecnologias mais empregadas por agricultores, pois independente da circunstância de chuvas ou não, assegura aos produtores uma colheita uniforme e diminuindo os riscos de perdas por falta de água. Manuseando as tecnologias estudas foi realizado um protótipo de sistema de irrigação localizada automatizada, de modo com que os sensores colhiam as informações do solo, posteriormente eram enviadas ao Arduino que por sua vez monitorava uma bomba hidráulica responsável por irrigar o solo supervisionado pelo sensor. Depois de alguns testes efetuados com o protótipo ficou comprovado o poder de processamento do Arduino e a precisão na coleta de dados processados pelo sensor

Selective Serotonin Reuptake Inhibitor Therapy Reduces Time to Emergence and Arousal from TBI-induced Prolonged Coma: A Pilot Study
Authors: Danner K Omar
Published: March 2020

Objective: Traumatic Brain Injury (TBI) continues to be a significant cause of death and disability in the United States and is commonly due to sudden, forceful impacts to the head. This may lead to disruption of neurological and neurochemical functioning of the brain, resulting in coma (Glascow Coma Scale score (GCS) ≤ 8). The objective of this study is to evaluate the potential effect of Selective Serotonin Re-uptake Inhibitors(SSRI), sertraline, on improvement in the level of consciousness and motor function in patients with prolonged, refractory coma after severe TBI. It has been theorized that the administration of SSRIs may shorten the time to emergence from comain trauma victims presenting with low GCS scores.

Methods: The data from 14 trauma patients with severe TBI and Refractorycoma (RC) as defined by a GCS score <8 (coma) for >6 days admitted to the surgical intensive care unit (SICU) at a busy urban level 1 trauma center was retrospectively collected and screened. The patients were started on sertraline between 7 to 21 days after sustaining TBI-induced coma, principally based on attending judgment and preference, and were compared to a control group of similar TBI-induced prolonged coma patients admitted to the ICU during the study period who did not receive SSRI therapy.

Results: In the study, 100% of the SSRI group became aroused to a GCS >8 and 66.7% (6/9) emerged to a minimally conscious state or regained consciousness based on a GCS scores >9 or 9T over a period of 11.9 days after initiation of therapy whereas 60% of control patients (3/5) emerged from coma.

Conclusion: SSRI therapy using Sertraline may be associated with shorter time to emergence and improved reactiveness in patients with prolonged refractory coma states post-TBI.
Host or Sponsor? Consumer Responses to Event Origins and Brand-related Event Leveraging
Authors: Skard Siv , Adam Sunniva , Engdahl Lise Fredrikke
Published: March 2020

Companies can engage in event marketing either by creating and hosting an event or by sponsoring a preexisting event. Although these are well-established event marketing strategies, consumer responses to event origin (hosting vs. sponsoring) have received limited scholarly attention.
This article presents an experimental study of event origin and brand-related event leveraging. The first purpose was to investigate consumers' evaluations of hosted versus sponsored events and hosting versus sponsoring companies, and to test mechanisms that may explain these differences.
The second purpose was to test consumer responses to brand-related leveraging activities for both types of events. Results show that consumers' evaluation of the event and the company differs significantly depending on the event origin, and that both types of events have much to gain from
brand-related leveraging. Key explanatory mechanisms for these effects are perceived sincerity of company motives, company–event fit, and perceived amount of resources invested in the event.

Performance Assessment of Micropollutants Removal From Water Using Advanced Oxidation Processes
Authors: Duarte António A. L. S. , Amorim Maria T. S. P.
Published: March 2020

In a global climate change scenario, reliable access to clean and safe water for all remains a great worldwide challenge for the twenty first century, as one of the most ambitious targets of several Sustainable Development Goals (SDG) established in the UN Agenda 2030. The increasing presence in the urban aquatic ecosystems of priority pollutants and contaminants of emerging concerning (CECs) have brought new challenges to the existing water treatment systems (WTS) concerning with public health protection and the of drinking water sources preservation. Advanced oxidation processes (AOPs) have been widely studied because of their potential as a complementary or alternative process to conventional wastewater treatment. Several AOPs using nanomaterials as photocatalyst can be particularly effective in the degradation of many toxic micropollutants, and enhance the multifunctionality, versatility and sustainability of WTS. This work presents a synthesis of the major results obtained in several pilot and lab-scale studies aiming to assess the performance of different low-cost catalytic processes used for antibiotic and pesticide removal. For each photo-oxidation reactors, different test scenarios are defined in order to evaluate the effects of several abiotic and hydraulic parameters on process kinetics and removal efficiencies. The experimental results were very promising, because antibiotic removal efficiencies achieved the maximum value of 96% for the photo-oxidation by water columns with suspended TiO2 nanoparticles, and 98% for the photocatalytic filtration performed by a porous medium coated with TiO2. In the photoelectrocatalytic reactor, the atrazine concentration has been fully removed for reaction times between 35 and 95 minutes.

Abstract To achieve a high level of advancement and prosperity, a country needs noble leader and people. Nobility is developed and nurtured by spiritual values that people learned since the earliest time in their lives. It is in the spiritual educations where the religious and highest philosophical values are embedded.Spiritual educational should not aim at achieving quantitative figures as the  learning objective. Spiritual educational, instead, shoud be capable of internalizing the values in the inner self of the people. Once deeply internalized, the values will be genuinely reflected in the day to day behaviour of all people. This writing highlights some of the universal value of Hindu. All of the highest values scattered in the Hindu scripture of Weda must be spreaded over and repeatedly hum to the heart of all human being. Making these values as a living guide will give rise to noble leader and society.       Keywords : Spiritual Educational, Noble leader and people

A Systematic Review and Network Meta-Analysis of Adjuvant Therapy for Curatively Resected Biliary Tract Cancers
Authors: Kish M. , Chan K. , Perry K. , Ko Y.J.
Published: March 2020

Background: Recent randomized controlled trials (rcts) have contributed high-quality data about adjuvant therapy in curatively resected biliary tract cancer (btc); however, a standard approach to treating those patients still has not been developed. Methods: We conducted a systematic review of published studies and abstracts up to and including June 2018, choosing rcts involving patients with btc receiving adjuvant chemotherapy after complete surgical resection. Network meta-analysis methods were used for indirect comparisons of overall survival (os) and relapse-free survival (rfs) for various adjuvant therapies. Results: Five rcts were included in qualitative synthesis, and three rcts (bilcap, prodige 12–accord 18, and bcat) had data sufficient for inclusion in the meta-analysis. Results from the indirect comparison demonstrated no significant improvement in os for capecitabine compared with gemcitabine or with gemcitabine–oxaliplatin (gemox), the hazard ratios (hrs) being 0.82 [95% confidence interval (ci): 0.53 to 1.27] and 0.86 (95% ci: 0.56 to 1.34) respectively. Similarly, no significant improvement in rfs was observed for capecitabine compared with gemcitabine or gemox. Conclusions: Although in the present analysis, we found no statistically significant improvements in os or rfs for capecitabine compared with gemox or gemcitabine, capecitabine can—until further prospective trials are completed—be considered the standard of care in the adjuvant setting based on a single randomized phase iii study.
Actor Imaging as Constituent Creative Transformation Process
Authors: Khlystun Olena
Published: March 2020

The article states that the actor’s mastering of the role is structurally divided into several stages, at each of which there is a certain accumulation of knowledge about the character of the play. The main theories of the structure of the creative process are illuminated in the theories of the three-act by P. Engelmayer, the three-stage model of A. Poincaré, and the four-stage model of creative thinking by G. Wallace, E. Getchinson. The imagination and creative activity of a person depend on the diversity of his previous experience, represented by the material from which the constructions of the presentation are created. It is noted that the most important feature of the imagination is its striving for embodiment. The actor designs the future physical embodiment of the character’s stage image. It is concluded that the imagination is constructed from the thoughts and visions of a person, simultaneously or alternately covering his mind. The actor profession is dominated by the emotional connection between the activity of the imagination and the act of reincarnation. The peculiarity of the actor’s imagination is the creative experience of the actor, and not his personal one. Imagination works in the preparatory analytical stage of the role as the accumulation of former emotional traces. In the process of implementing the role, these traces come to life, which leads to the act of reincarnation in the role.
Postmodern Personality: Ontological Self-dependance
Authors: Chmil Hanna , Korablova Nadiia
Published: March 2020

The article focuses on the triggers of ontological dependence as well as elucidates the construction / deconstruction of being by contemporary humans from the perspective of self-dependence. As a result, the real identity is substituted by simulacra and simulation in their different forms: avatars, images, masks in virtual reality. In view of this, ontological self-dependence cannot have any grounding because the identity serves as its basis.
A paradoxical situation has come about with respect to the growth of irrationality, which testifies to the unreasonableness of technological society in which even a rational and appropriate idea turns into irrational one. It makes humans trespass the boundaries of space and time, which leads to their addiction to modern technologies.
It should be mentioned that the concept of ontological self-dependence is a very urgent topic. It is associated with the implication of various meanings apart from those ones discussed in this paper. The recognition of the plasticity of the subjectivity seems to be important from the perspective of heuristics. The subjectivity seeks to be adequate to informational society and “the flowing present” (Z. Bauman) with low social dependence and the freedom of choice, with the feeling of social rootedness and at the same time the freedom to be whatever they want to be. Being self-dependent, such a personality manifests itself in the destruction of social fabric as a total representation and makes this fabric discrete, which allows the personality to regain the wholeness of ontological being both in the society and culture.

Published: March 2020

Background:Smear layer is considered to be the main contributing factor in better sealing and adhesion of a sealer.Objective:The aim of this study is to determine the sealing ability of two root canal sealers (AH Plus and tg). In the presence and absence of smear layerMethodology:Extracted teeth from patients visiting Sardar Begum Dental College 60 in numbers were used in this study. Specimens were divided in to two main groups (group1 and group 2) both groups were instrumented using a step back technique. Irrigation was done during instrumentation with one ml of 5.25% NaOCl solution. In group2 a final flush with 10 ml of 17% EDTA solution followed by 10ml of 5.25% NaOCl was used for smear layer removal. Each group then further divided in to two sub groups (n=15). After obturation specimens were kept in separate containers with wet gauze to maintain 100% humidity. The specimens were coated with nail polish except for apical 2mm. Specimens were then suspended vertically in two % methylene blue dye for 7 days. Longitudinal sectioning was done to determine the extent of dye penetration using a stereo microscope at X30 magnification. Student t test was used for statistical analysis (p≤ 0.05).Results:The results showed that in the presence of smear layer, mean apical dye leakage of AH Plus was2.89 mm and tg was 4.02 mm. While in the absence of smear layer the mean dye leakage of AH Plus was 2.23 mm and tg was 3.28 mm. Student t test was more than p value indicating non significant result for both sealers.Conclusion:Apical sealing ability of AH Plus is better than tg root canal sealer in the presence and absence of smear layer.

Published: March 2020

OBJECTIVE: The study aims to find the association between pollution caused by vehicular emission and development of respiratory diseases among traffic police personnel in Peshawar, Khyber Pakhtunkhwa, Pakistan. There is no doubt that pollution has damaged the environment but the victim is not the environment only. METHODOLOGY: The study included and focused on two variables; one was independent and the other was dependent variable. Therefore, an effort has been made in this research to investigate and evaluate the relationship among the two variables i.e. pollution (independent) and development of respiratory disease (dependent). A questionnaire was distributed among 250 traffic personnel but only 154 became the part of this study because the study included only non-smokers. The questionnaire consisted of 27 questions which comprised of open ended and closed ended questions. RESULTS: After gathering the data, correlation was run over the data to find the relationship. It found that there was a positive and significant relationship between pollution emission by vehicles and development of respiratory diseases. CONCLUSION: Therefore, hypothesis 1 was accepted and the null hypothesis was rejected.

MÖGLICHKEITEN UND UTOPIEN GEODÄTISCHER INFORMATIONSSYSTEME AUS DER SICHT EINES PRAKTIKERS
Authors: Simon Ernst F.
Published: March 2020

The author comes to the conclusion that the variety of terms and the differences in interpretation existing in geodetic
information systems must be restricted, and that all those systems have to be classified as geodetic information systems which are based on uniform
coordinates, fundamental importance being attached to the field of land cadasters, i e real estate property as the basic system. Instancing
the simultaneous existence of systems in the historical development from the land tax register to a multipurpose register and the necessity of
uniformity in surveying, not having been recognised in time, also with regard to the development of automation, the importance of a uniform
geodetic information system is outlined on the basis of the land cadastre in the Federal Republic of Germany. Citing the building cadastre
and the service line cadastre as examples, the author explains that it is impossible to carry out any necessary material developments in
the absence of certain basic conditions. Realisation of geodetic information systems is subject to political motivation, a wide-spread basic
structure, classical protection of property and practical multipurpose use, all of them offering possibilities of interrelation.

All features visible in the aerial photographs can be collected by traditional photogrammetric methods;
however, such techniques require high operator skills and are very time-consuming. The decision which photogrammetric method
uses in mapping is primarily economic, also workload, project deadline requirements and accurate data have to be considered.
Up-to-date developed automatic or semi-automatic systems are highly effective for 3D features extraction in urban areas.
The investigation objective is the comparison of analytical and digital semi-automatic photogrammetric mapping methods for

Supercatastrophic Disruption of Asteroids in the Context of SOHO Comet, Fireball, and Meteor Observations
Authors: Wiegert Paul , Brown Peter , Pokorný Petr , Ye Quanzhi , Gregg Cole , Lenartowicz Karina , Krzeminski Zbigniew , Clark David
Published: March 2020

Granvik et al. reported an absence of asteroids on orbits with perihelia near the Sun that they attribute to the “supercatastrophic disruption” of these bodies. Here we investigate whether there is evidence for this process among other bodies with similarly low perihelia: near-Earth asteroids, Solar and Heliospheric Observatory (SOHO) comets, and meter- and millimeter-sized meteoroids. We determine that no known near-Earth asteroids have past (last 104 yr) histories residing significantly inside the Granvik et al. limit, indirectly supporting the disruption hypothesis. The exception is asteroid (467372) 2004 LG, which spent 2500 yr within this limit and thus presents a challenge to that theory. Phaethon has a perihelion distance hovering just above the limit and may be undergoing slow disruption, which may be the source of its dust complex. We find that the rate at which ungrouped SOHO comets are observed is consistent with expected rates for the injection of small (25 m) class asteroids into the near-Sun region and suggest that this fraction of the SOHO-observed comet population may in fact be asteroidal in origin. We also find that there is an absence of meter-sized bodies with near-Sun perihelia but an excess of millimeter-sized meteoroids. This implies that if near-Sun asteroids disrupt, they do not simply fragment into meter-sized chunks but ultimately disintegrate into millimeter-sized particles. We propose that the disruption of near-Sun asteroids, as well as the anomalous brightening and destruction processes that affect SOHO comets, occur through meteoroid erosion, that is, the removal of material through impacts by high-speed near-Sun meteoroids.
A New Method for Deriving Composition of S-type Asteroids from Noisy and Incomplete Near-infrared Spectra
Authors: Sanchez Juan A. , Thomas Cristina , Reddy Vishnu , Frere Noah , Lindsay Sean S. , Mitchell Adriana
Published: March 2020

The surface composition of S-type asteroids can be determined using band parameters extracted from their near-infrared (NIR) spectra (0.7–2.50 μm) along with spectral calibrations derived from laboratory samples. In the past, these empirical equations have been obtained by combining NIR spectra of meteorite samples with information about their composition and mineral abundance. For these equations to give accurate results, the characteristics of the laboratory spectra they are derived from should be similar to those of asteroid spectral data (i.e., similar signal-to-noise ratio (S/N) and wavelength range). Here we present new spectral calibrations that can be used to determine the mineral composition of ordinary chondrite-like S-type asteroids. Contrary to previous work, the S/N of the ordinary chondrite spectra used in this study has been decreased to recreate the S/N typically observed among asteroid spectra, allowing us to obtain more realistic results. In addition, the new equations have been derived for five wavelength ranges encompassed between 0.7 and 2.50 μm, making it possible to determine the composition of asteroids with incomplete data. The new spectral calibrations were tested using band parameters measured from the NIR spectrum of asteroid (25143) Itokawa, and comparing the results with laboratory measurements of the returned samples. We found that the spectrally derived olivine and pyroxene chemistry, which are given by the molar contents of fayalite (Fa) and ferrosilite (Fs), are in excellent agreement with the mean values measured from the samples (Fa28.6±1.1 and Fs23.1±2.2), with a maximum difference of 0.6 mol% for Fa and 1.4 mol% for Fs.

We report the observations of solar system objects during the 2015 campaign of the High cadence Transient Survey (HiTS). We found 5740 bodies (mostly Main Belt asteroids), 1203 of which were detected in different nights and in g′ and r′. Objects were linked in the barycenter system and their orbital parameters were computed assuming Keplerian motion. We identified 6 near Earth objects, 1738 Main Belt asteroids and 4 Trans-Neptunian objects. We did not find a g′−r′ color–size correlation for 14 < H

g′ < 18 (1 < D < 10 km) asteroids. We show asteroids’ colors are disturbed by HiTS’ 1.6 hr cadence and estimate that observations should be separated by at most 14 minutes to avoid confusion in future wide-field surveys like LSST. The size distribution for the Main Belt objects can be characterized as a simple power law with slope ∼0.9, steeper than in any other survey, while data from the 2014 HiTS campaign has a distribution consistent with previous ones (slopes ∼0.68 at the bright end and ∼0.34 at the faint end). This difference is likely due to the ecliptic distribution of the Main Belt since the 2015 campaign surveyed farther from the ecliptic than did 2014's and most previous surveys.
The Magnetic Sensitivity of the Resonance and Subordinate Lines of Mg II in the Solar Chromosphere
Authors: del Pino Alemán T. , Trujillo Bueno J. , Casini R. , Manso Sainz R.
Published: March 2020

We carry out a theoretical study of the polarization of the solar Mg ii h–k doublet (including its extended wings) and the subordinate ultraviolet (UV) triplet around 280 nm. These lines are of great diagnostic interest, as they encode information on the physical properties of the solar atmosphere from the upper photosphere to the chromosphere–corona transition region. We base our study on radiative transfer calculations of spectral line polarization in one-dimensional models of quiet and plage regions of the solar atmosphere. Our calculations take into account the combined action of atomic polarization, quantum level interference, frequency redistribution, and magnetic fields of arbitrary strength. In particular, we study the sensitivity of the emergent Stokes profiles to changes in the magnetic field through the Zeeman and Hanle effects. We also study the impact of the chromospheric plasma dynamics on the emergent Stokes profiles, taking into account the angle-dependent frequency redistribution in the h–k resonance transitions. The results presented here are of interest for the interpretation of spectropolarimetric observations in this important region of the solar UV spectrum.

The galaxy cluster Zwicky 3146 is a sloshing cool core cluster at z = 0.291 that in X-ray imaging does not appear to exhibit significant pressure substructure in the intracluster medium (ICM). The published M
500 values range between

to (22.50 ± 7.58) × 1014
M
⊙, where ICM-based estimates with reported errors <20% suggest that we should expect to find a mass between

M
⊙ (from Planck, with an 8.4σ detection) and

M
⊙ (from ACT, with a 14σ detection). We investigate the ability to estimate the mass of Zwicky 3146 via the Sunyaev–Zel’dovich (SZ) effect with data taken at 90 GHz by MUSTANG-2 to a noise level better than 15 μK at the center and a cluster detection of 61σ. We derive a pressure profile from our SZ data, which is in excellent agreement with that derived from X-ray data. From our SZ-derived pressure profiles, we infer M
500 and M

Recent observations of global velocity gradients across and along molecular filaments have been interpreted as signs of gas accreting onto and along these filaments, potentially feeding star-forming cores and protoclusters. The behavior of velocity gradients in filaments, however, has not been studied in detail, particularly on small scales (<0.1 pc). In this paper, we present MUFASA, an efficient, robust, and automatic method to fit ammonia lines with multiple velocity components, generalizable to other molecular species. We also present CRISPy, a Python package to identify filament spines in 3D images (e.g., position–position–velocity cubes), along with a complementary technique to sort fitted velocity components into velocity-coherent filaments. In NGC 1333, we find a wealth of velocity gradient structures on a beam-resolved scale of ∼0.05 pc. Interestingly, these local velocity gradients are not randomly oriented with respect to filament spines and their perpendicular, i.e., radial, component decreases in magnitude toward the spine for many filaments. Together with remarkably constant velocity gradients on larger scales along many filaments, these results suggest a scenario in which gas falling onto filaments is progressively damped and redirected to flow along these filaments.

Introduction: Chagas disease (CD) remains a public health concern in several Latin American countries. At global level, Bolivia has the highest CD burden and the Chaco region, in the southeast of the country, is the most affected area. We report the results of four serosurveys for Trypanosoma cruzi antibodies, carried out approximately ten years apart from each other, during the lapse 1987-2013, in different localities of the Bolivian Chaco.

Methodology: Four cross-sectional surveys were conducted in various localities, mostly rural, of the Bolivian Chaco, during the period 1987-2013.

Results: Although a reliable analysis of CD epidemiological trend is challenging, a partial reduction of anti-T. cruzi seroprevalence over the past four decades in the Bolivian Chaco may be assumed. In particular, in 1987 the exposure to T. cruzi in rural setting was universal since the first years of life, while it resulted gradually lower and age-dependent thereafter. Moreover, T. cruzi seroprevalence among women of reproductive age (15-45 years) has been persistently high in rural areas.

Conclusions: T. cruzi transmission is still active and CD remains a concern throughout the Bolivian Chaco. More efforts are needed in order to achieve a sustainable interruption of vector-borne CD transmission in this area.

BACKGROUND: Phacoemulsification surgery has the ability to deeply alter the segment anterior morphology, especially in eye with shallow anterior chamber (AC), narrow anterior chamber angle (ACA). However, the changes of anterior chamber depth (ACD) and ACA on the close angle suspect eyes after phacoemulsification have not been mentioned in many studies. So, we conduct this research.
AIM: To evaluate the alteration in the ACA and ACD after phacoemulsification in the close angle suspect eyes.
METHODS: Interventional study with no control group. Subjects were the primary angle closure suspect (PACS) eyes, that were operated by phacoemulsification with intraocular lens (IOL) at Glaucoma Department of VNIO from December 2017 to October 2018.
RESULTS: 29 PACS eyes with cataract were operated by phacoemulsification with intraocular lens. After 3 months of monitoring, the average ACD augmented from 2.082 ± 0.244 to 3.673 ± 0.222 mm. AOD500 increase from 0.183 ± 0.088 to 0.388 ± 0.132 μm, AOD750 increased from 0.278 ± 0.105 to 0.576 ± 0.149 μm. The TISA500 enlarged from 0.068 ± 0.033 to 0.140 ± 0.052 mm2, TISA750 enlarged from 0.125 ± 0.052 to 0.256 ± 0.089 mm2 at the third month (p < 0.01).
CONCLUSION: Phacoemulsification surgery increases the ACD and enlarged the angle in the PACS eyes.

Handicap psychique et société : cette chance !
Authors: Aoustin Nathalie
Published: March 2020

Le handicap psychique est une surprise pour la société : coup de tonnerre ou chance ? Le handicap psychique se définit par la prise en compte d’une différence. Il est possible, pour la personne en situation de handicap psychique, de s’insérer dans un cadre adapté, d’avoir sa place, y compris dans nos entreprises. Elle est porteuse d’une créativité essentielle à un certain art de vivre, sans quoi règnerait un productivisme dénué de sens. Le handicap psychique est un espace de poésie et de lien social, valeur immatérielle, bien précieux pour le quotidien de la société. À Toulouse, le gem Bon Pied Bon Œil met la participation au cœur de la réhabilitation et de l’insertion.
Du municipalisme au communalisme
Authors: Cossart Paula , Sauvêtre Pierre
Published: March 2020

De nombreuses tentatives municipalistes contemporaines se réfèrent à Murray Bookchin, le principal théoricien du municipalisme libertaire et du communalisme. Beaucoup de ces tentatives, bien qu’elles renouvellent parfois profondément la vie locale, ont cependant du mal à se défaire du cadre de la souveraineté municipale. Si elles cherchent de façon innovante à faire fonctionner autrement les institutions municipales, elles restent distinctes du communalisme de Bookchin qui implique la mise en place de contre-institutions fondées sur l’autogouvernement des assemblées populaires citoyennes. Les pratiques récentes qui se revendiquent des « communs » remettent ce débat en scène. Associé à la logique des communs, comme formes d’auto-organisations socio-économiques, le communalisme est en train de se redéfinir.
Au-delà de l’art, une existence conceptuelle : Lee Lozano et Stanley Brouwn
Authors: Robert Émilie
Published: March 2020

En dépit de ses revendications fondamentales, l’art conceptuel se heurte aux limites d’une dématérialisation et d’une objectivité idéalisées. Moins concernés par la définition de l’art (et ses investigations) que par l’expérimentation du concept en tant que tel, Lee Lozano et Stanley Brouwn optimisent les enjeux et préceptes parfois contradictoires de l’art conceptuel par le biais d’une pratique divergente, aussi radicale que cohérente. Sujets de leur propre conceptualisation, tous deux gagent d’une existence absolue en faisant de la généralisation de l’identité et de la disparition du champ de l’art les facteurs de leur application et de leur latence universelles.
Artification de la politique, désartification de l’art ? Esquisse d’un style militant dans quelques expositions au XXI e siècle
Authors: Fartas Nadia
Published: March 2020

Depuis une vingtaine d’années on peut observer en France dans le champ de l’art contemporain la présence d’expositions institutionnelles qui font appel aux formes d’expression du militantisme. Deux caractéristiques majeures rendent compte de ce processus particulier d’artification de la politique d’où résulte en partie une désartification de l’œuvre d’art : l’inscription d’objets militants dans des expositions et l’extension du style militant qui en découle au discours des commissaires d’exposition. Fondée sur le courant des études postcoloniales, l’exposition « Tous, des sang-mêlés » (2017, Mac/Val) en offre un cas exemplaire. Les œuvres d’art ne sont pas pleinement devenues des objets militants mais, nimbées de style militant, elles sont enserrées par le fonctionnalisme direct.
Équipement technique ou objets d’art ? Du geste outillé dans la cérémonie du thé japonaise
Authors: Toader Iulia
Published: March 2020

Dans les années 1900, la cérémonie du thé fut érigée en art total, comme la quintessence même de l’esprit japonais. Par-delà le biais des enjeux politiques de cette artification, le discours académique portant sur la cérémonie du thé a également été perméable à l’esprit contradictoire inhérent à cette pratique. Nous tentons de dépasser ces difficultés par une vision réticulaire de l’art telle que la défend Simondon dans sa techno-esthétique, tandis que la Glass Tea House Mondrian de Sugimoto Hiroshi offre une métaphore permettant d’approfondir la place de l’abstraction dans la voie du thé. Dans cette réflexion, au détriment de l’objet réel conçu comme une entité isolée, le geste technique, outillé, s’avère jouer un rôle plus déterminant que ne lui accorde la tradition.
La gloire du machiniste et les plaisirs de l’illusion en France à l’époque moderne (1645-1772)
Authors: Saudrais Anthony
Published: March 2020

De l’arrivée de Torelli à la cour de France en 1645 à la publication des quarante-neuf planches de l’ Encyclopédie (« THÉÂTRES » et « MACHINES DE THÉÂTRE ») en 1772, les machines de théâtre ont connu en France un processus de considération critique pour un art jusqu’alors minoré – au seul rang de « mécanique » – depuis les grandes figures de la philosophie grecque. L’intérêt suscité par la machinerie théâtrale chez les savants français fait écho, sur le plan philosophique, au triomphe du mécanisme cartésien dont le déclin, prononcé définitivement dans le troisième quart du xviii e  siècle par Rousseau et Diderot, annonce la mort d’une scénographie classique portée sur les plaisirs de l’illusion et le merveilleux mythologique.
Les orphelins mineurs confrontés à la monoparentalité et le droit
Authors: Monteil Marine
Published: March 2020

La fonction parentale, qui est organisée par principe sur une répartition égale des pouvoirs entre les parents, est déséquilibrée à la mort de l’un d’entre eux. Le parent vivant est désormais investi de plein droit de l’ensemble des attributs de l’autorité parentale et de l’administration légale ; il prend seul toutes les décisions relatives à la vie du mineur, le représente et assume l’entièreté de ses besoins matériels. Ses prérogatives sont intensifiées dès lors que les contre-pouvoirs accordés au prémourant disparaissent avec lui. Par ailleurs, depuis l’ordonnance du 15 octobre 2015, le parent vivant peut faire sans autorisation judiciaire tous les actes de gestion à l’exception de ceux énumérés aux articles 387-1 et 387-2 du Code civil. Ce système de liste d’actes proposé par les nouveaux textes ne protège pas suffisamment les intérêts du mineur orphelin [1] .
