Muhammed Âbid el-Câbirî’nin Üç Bilgi Sistemi Teorisi Üzerine Eğitimsel Bir Analiz
Authors: İPEK Fatih
Published: September 2022

Bu çalışmada Câbirî’nin “Üç Bilgi Sistemi” olarak ifade ettiği teorisinin eğitimsel açıdan analiz edilmesi amaçlanmıştır. Bu konunun seçiminde Câbirî’inin teorisinin en temelde İslam eğitim geleneği eleştirisiyle ilgili olduğu düşüncesi etkili olmuştur. Câbirî’nin doküman taraması yöntemiyle tespit edilen görüşleri literatürdeki çalışmalarla ve eğitim bilimleri alanına ait ilke ve kabullerle karşılaştırılmıştır. Câbirî’nin teorisinde İslâm kültürüne hâkim olan referans bilgi sistemlerinin sayısını üçtür: (1) “beyânî bilgi sistemi”, (2) “irfânî bilgi sistemi” ve (3) “burhânî bilgi sistemi”. Ona göre bu üç epistemolojik yaklaşım, tedvîn döneminden başlayarak, bütün zamanlarda ve bütün Müslüman toplumlarda, ayrı ayrı olarak, baskın biçimde bilgiyi üretme ve kullanma tarzı olmuştur. Câbirî üç bilgi sisteminin (beyânî, burhânî, irfânî) hem ayrı ayrı var olmasını hem de birbirleriyle karışmasını İslâm medeniyetinin bir türlü atlatamadığı entelektüel, siyasî ve kültürel buhranların nedenleri arasında görmektedir. Ona göre üç farklı bilgilenme sisteminin olması İslâm medeniyeti açısından toplumsal ve zihinsel parçalanma ile sonuçlanan bir krize neden olmuştur. Bu krizi aşmak için yegâne yol; rasyonaliteyi ön plana çıkaran, geçmişteki Mağribî felsefenin mirasını dikkate alan yeni bir yapılanma dönemine girmektir. Câbirî’nin İslâm kültüründe bilginin üretilmesi ve değerlendirilmesi konusundaki tespitlerinde eğitimsel açıdan bazı sorunlar bulunmaktadır. Onun insanın bütünlüğünü ve insanın Allah ve evrenle ilişki biçimlerini göz ardı ederek bilgi sistemlerinin birbirinden bağımsız, ayrık ve düşman sistemler gibi yansıtması bu sorunların başında gelmektedir. Belirli bir insan tasavvuru ortaya koymadan üretilmiş olan bu teoride epistemolojik yaklaşımların ortaya çıkışındaki psikolojik yönelimler göz ardı edilmiştir. Onun entelektüel becerileri doğrudan milliyet (kalıtım) ve coğrafya (sosyo-kültürel yapı) ile ilişkilendirmesi ise teorisinin diğer önemli bir sorunudur. Bütün bunların yanı sıra onun, tarihi süreçte bilgi sistemlerinin baskın oluşunda ya da bilgi sistemleri arasında gezinti yaşanmasında toplumsal ihtiyaçları ve dönemsel şartları yeterince tahlil edemediği de söylenebilir. Bu açıdan Câbirî’nin tarihi, felsefi ve sosyolojik perspektifinin yanı sıra eğitsel perspektifi de kullanması gerektiği görülmektedir. Eğer İslâm eğitim geleneğindeki yapılara ve uygulamalara detaylı bir biçimde eğilmiş olsaydı belli açılardan Câbirî’nin teorisi indirgemeci ve katı determinist olmaktan kurtulabilecekti. Zira Câbirî’nin bir kriz olarak gördüğü üç ayrı bilgi sisteminin mevcudiyeti eğitimsel perspektifle bakıldığında bazı açılardan fırsat olarak görünmektedir.
Syntactic complexity in Japanese dialects
Authors: Li Wenchao
Published: September 2022

This study attempted the clustering of Japanese dialects at a syntactic level in light of dependency grammar. it is Kagoshima, a southwestern area of Japan, that bears the longest mean dependency distance (1.7851) and Akita of the north-eastern prefecture that shows the shortest mean dependency distance (1.1805). A test of Euclidean distances and clustering based on the MDD brings to light that, the north-eastern and north Kinki areas tend to bear a shorter MDD, indicating a less complex syntax in spoken dialect; the Kantoo and Chuubu, south Kinki, and Shikoku areas tend to present a medium syntactic complexity; the south areas tend to present long MDDs. In a broader sense, the more northward the region, the deeper the syntactic complexity of spoken dialect. The longest DD (3.4) is detected in Gifu prefecture. This has to do with its location, between eastern and western Japan, connected to seven prefectures: Toyama, Ishikawa, Fukui, Shiga, Aichi, Mie and Nagano.

In other to improve the ability of decision-makers to prepare for and deal with the unforeseen circumstances resulting from climate change as consequences of precipitation fluctuations, extreme and torrential rainfall. It is important to provide a more complete understanding of the range and likelihood of rainfall patterns a location could receive using a probabilistic model whose parameters might complement or even replace such common measures as the mean, median, variance, minimum, maximum and quartile values as major descriptors of rainfall at such location. Daily precipitation totals can be approximated by the gamma distribution as it is bounded on the left at zero and positively skewed indicating an extended tail to the right which suit the distribution of daily rainfall and accommodate the lower limit of zero which constrains rainfall values. This paper presents the comparison between Maximum Likelihood Estimation (MLE) of closed & open form solutions and Method of Moment Estimation (MME) of location and scaling parameters of the two-parameter gamma distribution, the parameters were estimated using MME and MLE with their performance adjudged and the result obtained showed that the closed-form solution of the MLE outperformed the open form solution and MME by comparing their estimates for the scaling parameter.

Published: September 2022

It has been observed that device inspiratory muscle warm-up exercises (IMW-D), which has started to take place in general warm-up in recent years, contribute to performance in a positive fashion. In the literature, IMW-Ds are usually performed with 40% of maximum inspiratory pressure (MIP). There is not a single study explaining or determining the best percentage of MIP in both acute and chronic studies on IMW-Ds in the literature. Therefore, in this study, it was aimed to determine the most important pressure percentage to improve respiratory parameters in IMW-Ds. A total of 40 athletes with licenses in a federation between the ages of 12-14 participated in the study. Participants underwent IMW-D with a powerbreathe plus respiratory exercise device at 15%, 30%, 40%, 45%, 50% and 60% of the MIP on different days, and immediately following these exercises were performed with a spirometer, respiratory parameters were measured as (FVC, FEV1, PEF). Kruskal Wallis H test was used in order to determine the difference between measurements. As a result of statistical analysis, it was found that while there was significant difference in PEF values between 15% and 40%, 45% of MIP; and the highest improvement was 45%, 50% and 60% of MIP in FVC, FEV1 and PEF values. It can be suggested that sedentary people and athletes who want to improve their respiratory parameters can also train with 45%, 50% and 60% of MIP without depending on 40% of the MIP applied only as given in the literature for a higher improvement in their IMW-D.

This work deals with the biological activity of the essential oils of an Algerian plant (Cotula cinerea) which belongs to the Asteraceae family. The study was carried out in the south-west of Algeria. We chose essential oils which are natural substances thanks to their numerous anti-infectious, antioxidant and antibacterial properties, etc. The objective of this work is to study the acute toxicity as well as the evaluation of the anti-inflammatory properties of the essential oils of both organs (leaves and flowers) of Cotula cinerea. As methodological approaches, we used the hydrodistillation technique to obtain the essential oils from leaves and flowers. Thus, the acute toxicity was determined by Lorke's method and the anti-inflammatory activity was evaluated by measuring the plantar oedema of mice induced by carrageenan. The results show that the essential oil extracts of the leaves and flowers are low toxic substances with LD50s of 1131.37 mg/kg and 1264.91 mg/kg respectively. They also show a considerable anti-inflammatory effect at doses not exceeding 300 mg/kg with maximum percentages of 86.16% for leaves and 80.87% for flowers. These results show the efficacy of the essential oils of this plant and their therapeutic richness which can be used in traditional medicine for anti-inflammatory treatment. This study has provided additional knowledge on the biological activity of Cotula cinerea essential oils and has opened perspectives for the research of the active principles contained in this species as well as the application of biotechnology to know the molecular mechanism and valorise this natural wealth.
Protective role of Curcumin in Di-n-butyl phthalate-induced damage on reproductive parameters in male Rabbits
Authors: Rihani Lamia
Published: September 2022

Di-n-butyl phthalate (DBP) is a ubiquitous environmental pollutant, extensively used as a plasticizer in many products including plastics, cosmetics, and medical devices. Some studies have shown that DBP has potential testicular toxicity. The aim of this study was to explore the adverse effects of DBP on testes and epididymis weight, sperm head counts, sperm motility, abnormal changes in sperm morphology, in male rabbits as well as to assess ameliorating role of curcumin. The present study was carried out to evaluate the protective effects of curcumin (from the rhizome, Curcuma longa L.) on the di-n-butylphthalate (DBP)-induced damage in reproductive rabbits. The dose of curcumin (60 mg/kg) and curcumin(60 mg/kg) plus DBP 700 mg/kg were administered per gavage to male rabbits for 30 consecutive days and reproductive parameters were determined.. The results indicated that DBP administration (700 mg/kg) significantly decreased testosterone level, count and motility of sperms, and testis weight compared to control group. However, administration of curcumin with DBP increased reproductive indices in most of the groups compared to DBP-treated groups. DBP-treated rabbits showed marked degeneration of the seminiferous tubules with necrosis and defoliation of spermatocytes .Our research demonstrated that DBP-induced injuries in spermatological parameters and histological structure of testis were recovered by treatment with curcumin Thus, it seems that curcumin inhibits DBP-induced adverse effects on reproductive parameters. The protective effects of these compounds may be due to their intrinsic antioxidant properties and as such may prove useful in combating phthalate-induced reproductive toxicity.

Published: September 2022

The literature suggest that date palm cultivars are a promising source of beneficial compounds, of which many cultivars around the world are gaining increasing interest due to their important biological properties. Hence, there is a need to be further investigated in Algerian date palm cultivars. The purpose of this study was to identify the effect of the storage temperature variation on the content of phenolic compounds in dates for some Algerian cultivars (Deglet Nour, Ghars, Mech Degla, Degla Baidha). The fruits of the four cultivars were preserved in varying degrees of temperature (4°C and ambient temperature). To determine the effect of the varying degrees of storage temperature on the content of phenolic compounds, the total phenols, flavonoids and total tannins were measured. The differences were noted for the five studied parameters. We found that there was a storage temperature effect on the pH parameter with a value of 6.17 (±0.04), and low effect on electric conductivity. Determination of total polyphenols in dates shows high degrees in Degla Baidha cultivar stored at 4 °C (574.46 mg EAG/100 g) compared to those of Mech Degla, Ghars and Deglet Nour (564.46, 554.35 and 526.39 mg EAG/100 g respectively), and for the same cultivars stored in high temperature, the total polyphenols content was found lower. The total tannin and flavonoid content show a significant difference for date cultivars, where the best estimated levels of the two components in Degla Baidha cultivar at 4 °C (110.43 mg EAT/100 g and 4.51 mg QE/100 g respectively). The results revealed that there was insignificant effect of variation in storage temperatures on flavonoids and total tannins, but the effect was strong, with respect to total polyphenols. Considerable quantities of these compounds were recorded at a temperature of 4 °C. These findings reveal the richness of these Algerian cultivars in phenolic compounds compared to others.
StraKLIP: A Novel Pipeline for Detection and Characterization of Close-in Faint Companions through the Karhunen–Loéve Image Processing Algorithm
Authors: Strampelli Giovanni M. , Pueyo Laurent , Aguilar Jonathan , Aparicio Antonio , Duchêne Gaspard , Robberto Massimo
Published: September 2022

We present a new pipeline developed to detect and characterize faint astronomical companions at small angular separation from the host star using sets of wide-field imaging observations not specifically designed for high-contrast imaging analysis. The core of the pipeline relies on Karhunen–Loéve truncated transformation of the reference point-spread function (PSF) library to perform PSF subtraction and identify candidates. Tests of reliability of detections and characterization of companions are made through simulation of binaries and generation of receiver operating characteristic curves for false-positive/true-positive analysis. The algorithm has been successfully tested on large HST/ACS and WFC3 data sets acquired for two HST Treasury Programs on the Orion Nebula Cluster. Based on these extensive numerical experiments we find that, despite being based on methods designed for observations of a single star at a time, our pipeline performs very well on mosaic space-based data. In fact, we are able to detect brown-dwarf-mass companions almost down to the planetary-mass limit. The pipeline is able to reliably detect signals at separations as close as ≳0.″1 with a completeness of ≳10%, or ∼0.″2 with a completeness of ∼30%. This approach can potentially be applied to a wide variety of space-based imaging surveys, from data in the existing HST archive to near-future JWST mosaics and future wide-field Roman images.
Nonlinear Outcome of Coagulation Instability in Protoplanetary Disks. I. First Numerical Study of Accelerated Dust Growth and Dust Concentration at Outer Radii
Authors: Tominaga Ryosuke T. , Kobayashi Hiroshi , Inutsuka Shu-ichiro
Published: September 2022

Our previous linear analysis presents a new instability driven by dust coagulation in protoplanetary disks. The coagulation instability has the potential to concentrate dust grains into rings and assist dust coagulation and planetesimal formation. In this series of papers, we perform numerical simulations and investigate the nonlinear outcome of coagulation instability. In this paper (Paper I), we first conduct local simulations to demonstrate the existence of coagulation instability. Linear growth observed in the simulations is in good agreement with the previous linear analysis. We next conduct radially global simulations to demonstrate that coagulation instability develops during the inside-out disk evolution owing to dust growth. To isolate the various effects on dust concentration and growth, we neglect the effects of back-reaction to a gas disk and dust fragmentation in Paper I. This simplified simulation shows that neither back-reaction nor fragmentation is a prerequisite for local dust concentration via the instability. In most runs with weak turbulence, dust concentration via coagulation instability overcomes dust depletion due to radial drift, leading to the formation of multiple dust rings. The nonlinear development of coagulation instability also accelerates dust growth, and the dimensionless stopping time τ
s reaches unity even at outer radii (>10 au). Therefore, coagulation instability is one promising process to retain dust grains and to accelerate dust growth beyond the drift barrier.
Radio Jet Proper-motion Analysis of Nine Distant Quasars above Redshift 3.5

Published: September 2022

Up to now, jet kinematic studies of radio quasars have barely reached beyond the redshift range z > 3.5. This significantly limits our knowledge of high-redshift jets, which can provide key information for understanding the jet nature and the growth of black holes in the early universe. In this paper, we selected nine radio-loud quasars at z > 3.5 which display milliarcsecond-scale jet morphology. We provided evidence of the source nature by presenting high-resolution very long baseline interferometry (VLBI) images of the sample at 8.4 GHz frequency and making spectral index maps. We also consider Gaia optical positions that are available for seven out of the nine quasars for better identification of the jet components within the radio structures. We find that six sources can be classified as core–jet blazars. The remaining three objects are more likely young jetted radio sources, compact symmetric objects. By including multiepoch archival VLBI data, we also obtained jet component proper motions of the sample and estimated the jet kinematic and geometric parameters (Doppler factor, Lorentz factor, and viewing angle). Our results show that at z > 3.5, the jet’s apparent transverse speeds do not exceed 20 times the speed of light (c). This is consistent with earlier high-redshift quasar measurements in the literature and the tendency derived from low-redshift blazars that fast jet speeds (>40c) only occur at low redshifts. The results from this paper contribute to the understanding of the cosmological evolution of radio active galactic nuclei.
Cosmic Reionization on Computers: Physical Origin of Long Dark Gaps in Quasar Absorption Spectra
Authors: Gnedin Nickolay Y.
Published: September 2022

I explore the properties of “dark gaps”—regions in quasar absorption spectra without significant transmission—with several simulations from the Cosmic Reionization On Computers (CROC) project. The CROC simulations in the largest available boxes (120 cMpc) come close to matching both the distribution of mean opacities and the frequency of dark gaps, but alas not in the same model: the run that matches the mean opacities fails to contain enough dark gaps and vice versa. Nevertheless, the run that matches the dark gap distributions serves as a counterexample to claims in the literature that the dark gap statistics requires a late end to reionization—in that run reionization ends at z = 6.7 (likely too early). While multiple factors contribute to the frequency of large dark gaps in the simulations, the primary factor that controls the overall shape of the dark gap distribution is the ionization level in voids—the lowest-density regions produce the highest transmission spikes that terminate long gaps. As the result, the dark gap distribution correlates strongly with the fraction of the spectrum above the gap detection threshold and the observed distribution is matched by the simulation in which this fraction is 2%. Hence, the gap distribution by itself does not constrain the timing of reionization, although it may do so in combination with the distribution of mean opacities.

Published: September 2022

BACKGROUND: Sepsis-induced myocardial dysfunction (SIMD) is an increasingly recognized form of transient cardiac dysfunction in sepsis patients.
AIM: The aim of the study was to evaluation of N-terminal pro brain natriuretic peptide (NT-pro BNP) as a predictor of SIMD and poor outcome in patients with sepsis or septic shock.
METHODS: Forty patients were enrolled and divided into: Group 1 with sepsis; Group 2 with septic shock. Each group was subdivided according to the presence or absence of cardiomyopathy. Echocardiography, NT-pro BNP - assay on the 1st and 2nd days of admission - were performed.
RESULTS: NT-pro BNP level was significant predictor for cardiomyopathy in all case group with 75% sensitivity, 70% specificity (cutoff level >334 pg/ml) on 1st day of admission and 65% sensitivity, and 80% specificity (cutoff level >325 pg/ml) on 2nd day. On subgroup analysis, pro-BNP had 70% sensitivity, 90% specificity; cutoff level >334 pg/ml for prediction of cardiomyopathy in sepsis group and 70% sensitivity and 80% specificity; cutoff level >357pg/ml in septic shock group. Pro-BNP on 2nd day was excellent predictor of mortality in septic shock group with 100% sensitivity and specificity; cutoff level >350 pg/ml.
CONCLUSION: N terminal pro-BNP is a good diagnostic and prognostic indicator for cardiomyopathy and mortality in septic patients.

Authors: Mohamed Samar Ramadan , Fadl Hend A. , Tork Islam , Omar Tarek , El-Barrany Usama , Elshatory Ahmed
Published: September 2022

BACKGROUND: Multiple sclerosis (MS) is a demyelinating inflammatory disease of the central nervous system white matter. Both of environmental and genetic factors have been implicated in its pathogenesis. Heavy metals generate free radicals causing alteration in genetic material and blood-brain barrier damage. In addition, intracellular accumulation of certain heavy metals can trigger autoimmune reaction against myelin proteins and nerves cytoskeletal proteins.

AIM: We aimed to analyse complex profile of altered heavy metals accumulation in multiple sclerosis and relationship with copper and zinc homeostasis.

METHODS: The present study was carried out in the period between September 2019 and May 2021 on 86 MS Egyptian patients and 86 age and gender matched healthy controls. Whole blood levels of lead (Pb), mercury (Hg), and Cadmium (Cd) in microgram/liter (μg/L) in addition to Zinc (Zn) and Copper (Cu) in milligram/liter (mg/L) were quantitated using the Agilent ICP-MS-MS. The current study also discussed physiological-toxic metals interactions in these patients.

RESULTS: We demonstrated significant relations between toxic heavy metals levels and MS suggested by significantly higher levels of Pb, Hg, and Cd and significantly lower levels of Zn and Cu as well as Cu/ Zn in MS patients than controls. Besides, it could be assumed that; physiological heavy metals homeostasis limits the accumulation of toxic heavy metals that share absorption and transport binding sites, suggested by the significant negative correlations between whole blood levels of Cu and both of Hg and Pb.

CONCLUSION: A complex profile of altered elements rather than a single element imbalance in MS pathogenesis is suggested.
Comparative Study between Ultrasound-Guided Quadratus Lumborum Block Type 2 Versus Lumbar Epidural Analgesia as a Perioperative Analgesic Technique for Pelvic Cancer Surgeries
Authors: Elwakil Mohammad , Tharwat John , Abbas Dina , Elwaseef Mohammad , Elgendy Sameeh
Published: September 2022

Background: The effect of the quadratus lumborum block (QLB) is believed to result from a spread of LA from its lumbar deposition cranially into the thoracic paravertebral space.The aim of this study is to compare the analgesic efficacy of an Ultrasound-guided quadrates lumborum type II block versus lumbar epidural analgesia or conventional analgesia after pelvic cancer surgeries regarding intraoperative fentanyl consumption, postoperative pain scores and morphine consumption in the first 24 hours.Methods: This study was conducted on 90 patients of American Society of Anesthesia (ASA) physical status II scheduled for elective pelvic cancer operations. Patients were randomized into three equal groups of 30 patients: Group Q: received bilateral QLB by 20ml of 0.25% bupivacaine in each side, Group E: received continuous lumbar epidural block analgesia ((0.125 % bupivacaine at infusion rate of 6ml/hour for 24 hours). Group C (Control group): were transferred to operation room without further intervention.Results: End tidal sevoflurane was significantly decreased in group Q than group C and in group E than group C at all time measurements. VAS at 0.5, 1, 8. 16 and 24 hours was significantly increased in group C than Group Q and group E. Time to first rescue dose of morphine was significantly increased in Group E than Group Q (P1 <0.001) and was significantly decreased in group C than Group Q (P2 <0.001) and was significantly decreased in group C than Group E (P3 <0.001). Total dose of morphine in 1st 24 hours was significantly increased at group C than group Q and group E (P <0.001) but there was an insignificant difference between Group Q and E.Conclusion: When compared to the control group, QLB and epidural block resulted in decreased VAS, intraoperative sevoflurane and fentanyl use and postoperative morphine consumption with a greater level of patient satisfaction. Epidural block, on the other hand, resulted in less intraoperative sevoflurane usage than QLB.

Published: September 2022

BACKGROUND: Pregnancy state affects the immune regulation including physical barrier, innate, and adaptive immunity-related to susceptibility of infections and increasing risk for severe to critical case of COVID-19. Further, high risk of thrombosis becomes a challenge in the management of COVID19 in pregnancy due to the strong association with worse outcome.

CASE REPORT: Here, we present three cases of pregnant women infected with COVID-19 pneumonia with different outcomes in maternal and fetal condition related to high-risk thrombosis. Serial inflammatory markers were needed to the early detect the disease progressivity in pregnant women with COVID-19. Further, complete assessment of fetus including reverse transcriptase-polymerase chain reaction and chest X-ray must be performed to the early diagnosis of COVID-19 in neonatal whose mother was infected by SARS-CoV-2.

CONCLUSION: Pregnancy state affects the immune regulation including physical barrier, innate, and adaptive immunity-related to susceptibility of infections and increasing risk for severe to critical case of COVID-19. Further, high risk of thrombosis becomes a challenge in the management of COVID19 in pregnancy due to the strong association with worse outcome. Although fetal transmission of COVID-19 to fetus remains unclear, complete assessment of fetus including RT-PCR, and chest X-ray must be performed to the early diagnosis of COVID-19 in neonatal whose mother was infected by SARS-CoV-2.
Description of the female of Platycheirus altomontis Merlin & Nielsen in Nielsen, 2004 (Diptera, Syrphidae) with notes on the occurrence and hilltopping behaviour of rare French montane and Alpine Syrphidae
Authors: Van de Meutter Frank
Published: September 2022

A focused search in very high (2500–3200 m asl) Alpine mountain tops in France resulted in the discovery of the very rare Alpine-endemic syrphid Platycheirus altomontis Merlin & Nielsen in Nielsen, 2004, including its hitherto unknown female. A description of the female is given and further complemented with behavioural observations of this species with special reference to hilltopping. Additional records and behavioural observations are provided for rare and new species for the French fauna from the montane and Alpine habitat with focus on species of high altitude (>2750 m) and hilltopping behaviour. The species Rohdendorfia alpina Sack 1938 is new to France and was observed in large numbers at scree slopes above 2750 m and males were found sitting at hilltops up to 3200 m. Hilltopping behaviour of Syrphidae was observed over the whole altitudinal range visited, and multiple species engaged in this behaviour even at above 3000 m. Hilltopping appears to be more common in some genera (e.g. Parasyrphus and Pipizella) than in others and may be linked to specific phenotypes in some species. The latter was observed for the species Cheilosia melanura (Becker, 1894) of which at high hilltops much smaller males were found than at lower altitudes.
Le choix en assurance affecte-t-il les comportements préventifs des assurés ?
Authors: Plantier Morgane
Published: September 2022

À l’aide d’une expérimentation en laboratoire, cette étude compare le niveau d’effort de prévention fourni par les participants pour diminuer la probabilité de risque auquel ils font face, entre le cas où ils ont au préalable choisi un contrat d’assurance dans un menu ; et le cas où le contrat leur a été imposé. L’évidence expérimentale révèle un impact négatif de l’introduction de l’option de choix du contrat sur les comportements préventifs des assurés. Outre l’effet négatif du taux de couverture sur l’effort de prévention (effet d’aléa moral), le fait de laisser le choix du contrat aux participants diminue le niveau d’effort de prévention qu’ils sont prêts à fournir ensuite, à niveau de couverture donné.

University student perception of sustainability and environmental issues
Authors: Genovese Elisabetta
Published: September 2022

There is a global consensus among scientists that human-caused climate change is threatening the environment and communities worldwide and that major changes must be implemented to reduce the increasing rate of CO2 emissions. Moreover, environmentally unsustainable practices are both endangering and degrading the quality of life on Earth. One major and often underestimated aspect of this problem is the difference in individual environmental risk perception and evaluation. It is evident that the responsibility for Earth's future lies in the hands of young generations and raising their awareness of environmental issues is a substantial challenge for education institutions. Students need to develop new values, skills and behaviors to foster sustainable development. As institutions of higher education, universities have a major impact on society and play a key role in the development of environmental awareness in young people. The paper describes the results of a survey administered to students in the Cultural Geography B course at the University of Torino. The purpose of the analysis was to determine if there is a relationship between environmental perception, attitude and behavior. The results showed that the students had a good knowledge of and positive attitude to the environment. However, as past studies have already revealed, there is a gap between their awareness and proactive environmental behaviors. Knowledge does not appear to be the only variable needed and other hypotheses should be explored to change the behavior of young generations. This study provides some insights for implementing integrated sustainability processes and engaging students. Moreover, the results will support the structuring of a future Geography course that focuses on sustainable development and environmental risk.
Kitaev Quantum Spin Liquid
Authors: HWANG Kyusung
Published: September 2022

Quantum spin liquid is a phase of matter featured with quantum entanglement and fractionalization, and it has been sought after in condensed matter. Kitaev quantum spin liquid has been of particular interest due to the emergent quasiparticles of Majorana fermion, which is proposed as a venue for quantum computations. Recently, experimental evidences for Majorana fermion have been reported in the Kitaev quantum magnet -RuCl3. Half-integer quantized thermal Hall effect and field-angle dependent Majorana gap were experimentally observed. In this article, we review physics of Kitaev quantum spin liquid and recent advances in experiments.
Des corps-en-train-de-se-faire. Ce que la compost-philosophie peut apprendre du danser
Authors: Bigé Emma
Published: September 2022

Que se passe-t-il pour la théorie qui se met à l’écoute des savoir-sentir des danseureuses ? À bien tendre l’oreille, il apparaît que « le corps » – obsession contemporaine – n’est pas toujours le domaine privilégié d’investigation de la danse. Il y a tout un monde de sentis intérieurs ou atmosphériques, nanoscopiques ou collectifs, qui se déclarent lorsqu’on s’efforce de se défaire de l’écran de fumée dressé par lecorps, concept qui, trop facilement et quoi qu’on fasse, traîne derrière lui la douloureuse histoire de sa séparation d’avec l’esprit et l’intériorité – suivant le schéma des dualismes modernes qui vont du schisme nature/culture aux délétères binarismes de genre, de race et d’espèces. Cet article, écrit depuis les temps troubles du Capitalocène et de la sixième extinction de masse, part à la recherche des stratégies philosophiques (chez Erin Manning) et chorégraphiques (chez Steve Paxton) qui se sont développées pour renommer les mouvementements qui inquiètent le corps séparé et donnent quelques motifs de se rappeler à l’humus dont nous sommes faites.
Le musée de la danse : mouvement et répétition
Authors: Popa Délia
Published: September 2022

Si l’on est habitué à concevoir le mouvement comme un déplacement d’un point de l’espace vers l’autre, y a-t-il autre chose qui se joue dans les mouvements de notre corps qui ne relève pas de ce type de déplacement et que la danse est susceptible de révéler ? Quel est le rapport entre danse et répétition ? Et dans quelle mesure la répétition affecte-t-elle notre rapport à l’espace social dont nous faisons partie ? A partir des réflexions développées autour du « Musée de la danse » conçu par le chorégraphe français Boris Charmatz, cet article explore le rôle des mouvements répétitifs dans la constitution du sens des lieux que nous fréquentons, ainsi que l’incidence de ces lieux sur notre manière de nous mouvoir les uns en rapport avec les autres. Notre intention est de souligner la dimension sociale et politique des mouvements que nous effectuons dans l’espace, à travers une analyse phénoménologique de leur dimension esthétique.
Qu’est-ce qui fait art en danse classique ?
Authors: Basselier Laetitia
Published: September 2022

Si le concept d’artification tel qu’il est défini par Nathalie Heinich et Roberta Shapiro paraît à première vue peu pertinent pour saisir les enjeux actuels de ce genre « artifié » par excellence que constituerait la danse classique, leur mise à l’épreuve mutuelle s’avère soulever plusieurs problèmes, qui conduisent tant à interroger ce qui fait art en danse classique qu’à complexifier le concept d’artification, et à souligner quelques unes de ses spécificités dans le domaine chorégraphique. Plus généralement, il s’agira de montrer qu’un questionnement philosophique sur la danse classique gagne à dialoguer avec des travaux d’histoire et de sociologie de la danse.
The Ambivalences of Smart Cities
Authors: Santaella Lucia , Napole Luiz Felipe
Published: September 2022

This chapter deals with the emerging urban spaces of the 21st century, at first named as sentient cities and then as smart cities, which result from the growth of megalopolises. This growth was accompanied by the expansion of disruptive technologies such as the internet, surveillance cameras, and sensors throughout the space interfering with domestic, public, corporate, and government affairs. The purpose of the chapter is to analyze the ambivalences that result from the inevitability of the use of intelligent technologies to guarantee the management and administration of the urban life, on the one hand, but the increase on the systems of control and surveillance, on the other side, to the point of converting the ambivalences into paradoxes.
Mitigating the Pandemic Through Creativity
Authors: Bertrand Cabral Clara , Roders Ana Pereira , Albuquerque Rosana
Published: September 2022

Culture and creative industries are nowadays a most relevant dimension of cities' economies and a fundamental asset of the tourism sector. The rise of COVID-19 has strongly and negatively impacted these resources, triggering responses from international organizations and municipalities eager to address the emergent constraints and difficulties experienced by society. This chapter analyzes how UNESCO assisted state members in dealing with the situation through the dissemination of information, studies, and reports, and how cities reacted to lockdowns, reduction of revenues, and the need to support and encourage their citizens. The analysis of information provided by UNESCO Creative Cities and World Heritage Cities concerning activities implemented provide a broad image of cities' reactions to the pandemic and of creative field distinctiveness.
COVID-19 and Human Rights in a Fragile State
Authors: Sangreman Carlos , Faria Raquel Tavares , Turé Bubacar
Published: September 2022

This investigation aims to study the situation of human rights during the COVID-19 pandemic in Guinea-Bissau between January 2020 and January 2022. The research organized an inquiry to families and another to market sellers about the effects of the pandemic and the measures enacted by the government and presidency to contain it. A public hearing was also organized, with various entities from the high commission to trade unions, journalists, and the public order police, for information on how each institution saw its situation and action in this period. The conclusions of the analysis of all these qualitative and quantitative data allow us to affirm that the fragility of Guinea-Bissau has such a social weight that a disease that killed fewer people than malaria, diarrhea, or tuberculosis did not overcome the problems of human rights stemming from poverty, institutional fragility, and low incomes in general.
Virtual Tourism as a Pedagogical Practice
Authors: Eliseu Sérgio Rafael , Sousa Marta Noronha , Berlinde Ãngela , Bogdan Mihaela
Published: September 2022

Post-pandemic anxiety and potential new outbreaks of this and other diseases could be a push, started long ago with the explosion of low-cost mobile devices, for immersive technologies, such as augmented reality, virtual reality, and mixed reality, to assert themselves as credible solutions in contrast to traditional ways of knowing the world. Effectively, these technologies already offer safe alternative ways to “travel” through continuous and uninterrupted interactive experiences for travelers who do not want to give up their own private space, safety, and health. However, this possibility brings with it new questions and challenges, mainly in terms of the development of these experiences, more specifically in the academic and pedagogical field. The authors analyze a project that articulates, in a transdisciplinary way, contents of several curricular units attended by Erasmus students around a VR experience of one of the most emblematic places in the region, the famous Castro of Monte Mozinho.
To Identify the Evolution of Tourism Practices in a Sensitive Way Through Documentary
Authors: Cyrulnik Natacha
Published: September 2022

As an extension of the audiovisual work carried out for 15 years in the cities of the South of France, the tourist sites are filmed in turn as part of a new documentary series in order to try to better understand, through their narration, the daily life in these easily caricatured territories. While this series “Getting Out of From the Postcard” aimed to bear witness to the tourists who took precedence over these sites, the pandemic reoriented it by (re)presenting daily life in these places, which are both tourists and inhabitants.
MXene-Based Nanocomposite Photocatalysts for Wastewater Treatment
Authors: Li Gao , Raza Ali , Ali Sarfraz , Li Zhiwen
Published: September 2022

Two-dimensional (2D) MXene has been considered as a hotspot toward environmental photocatalysis because of its outstanding structural stability, highly efficient conductivity, and versatile hydrophilicity. As an efficient photocatalytic candidate, MXenes offer rapid photogenerated charge carrier isolation, thereby providing plentiful availability for surface functional groups in respect of light-harvesting promising materials, and additionally executing a suitable foundation in favor of superior photoconversion proficiency. This chapter summarizes a comprehensive analysis of recent studies on fabrication method for MXene photocatalysts and photocatalytic performance for contaminant degradations. More significantly, MXenes are frequently employed as cocatalysts to boost the efficacy of photocatalytic activities when combined with other traditional photocatalysts such as metal oxide, metal sulfide, g-C3N4, and so on. Furthermore, in an effort to disclose the unique qualities of MXene-based nanocomposites, the stability of MXene-based nanocomposite photocatalysts is briefly examined.
Designing and Structural Modification of Novel Biomaterials to Increase Their Bioefficacy Towards Decontamination of Cadmium
Authors: Singh Nirupama
Published: September 2022

Heavy metals have come up as a threatening pollutant in aqueous media, leading to life threatening consequences. Biomaterial has been a novel and innovative wing of Green Chemistry, eradicating the threats in a cost effective and clean manner. The present study has been focused on the successful removal of a life-threatening heavy metal Cd (II) from aqueous solution using biosorbent created using selected plants. The present study establishes the fact that carboxylic acid group plays an important role in the metal binding process using protection of COOH group by propylamination and esterification. We could also conclude that the enrichment of COOH group onto the biomaterial using synthetic modifications succination leads to the increase in the sorption efficiency.
Photodegradation of Thymol Blue Under Visible Light by the Novel Photocatalyst Titania/PAni/GO
Authors: Kumar Azad
Published: September 2022

The TiO2/PAni and TiO2/PAni/GO nanocomposites were prepared by one-step in situ oxidative polymerization of aniline hydrochloride using ammonium persulphate as an oxidant in the presence of powder of TiO2 nanoparticles cooled in an ice bath. The obtained nanocomposites were characterized by XRD, TEM, SEM, BET, FTIR, and DRS. The obtained results showed that TiO2 nanoparticles have been encapsulated by PAni. The FTIR characterization confirms that the TiO2/GO molecules are well combined with polyaniline structure. The maximum photodegradation of Thymol blue was found in TiO2/PAni/GO at 25 ppm concentration of dye, 1600 mg/L amount of photocatalyst, pH 7, and 120 min irradiation of visible light. Hence, the photocatalytic activity of Titania has been increased by the coating of PAni and Graphene oxide.
