How Person–Organization Fit Impacts Work Performance: Evidence from Researchers in Ten Countries during the COVID-19
Authors: Liu Xiao , Xie Cathy Ping
Published: June 2023

It is important to provide researchers with the support they need to improve the Person–Organization (PO) fit in order to manage the negative impact of COVID-19 on work performance. Underpinned by the PO fit theory, drawing upon the survey data of 2321 researchers from ten countries initiated by Nature in 2021, this paper discusses how the independent variables of person–organization fit and organizational resources impact work performance, a dependent variable, moderated by career stages via a factor and path analysis. The results show that organizational resources and PO fit have significantly assisted researchers in managing the negative impacts of COVID-19 on work performance. In terms of national heterogeneity, for developing countries, it is more important to provide more organizational support to researchers than PO fit. However, for developed countries, personal demands would be focused on improving PO fit, which would be helpful for researchers’ work performance more effectively than providing organizational support blindly. Therefore, in order to improve the efficiency of organizational support, those that fit less but had more helpful aspects should be increased appropriately, while those that fit more but were less helpful should be reduced accordingly. It implies that it would be significant to emphasize differentiated and career-stage-sensitive support to researchers in different countries to improve researchers’ wellbeing and organizational performance.

Published: June 2023

The development of halal tourism in Indonesia is the focus of the Indonesian government and MSMEs have an important role in supporting the development of halal tourism in Indonesia. This study aims to examine the relationship between marketing communication and Islamic financial literacy on Islamic financial inclusion and MSME performance in the halal-tourism sector. A covariance-based SEM technique utilizing LISREL software was used to analyze the data from this investigation. Nonprobability sampling was employed to collect the data, and the sample consists of 152 halal-tourism entrepreneurs. This study found a positive and significant association between Islamic financial inclusion and business performance. This study also found that there is a positive and significant association between Islamic financial literacy and Islamic financial inclusion. Marketing communication and Islamic financial inclusion have a positive relationship, but it is insignificant. This study implies that to establish a halal-tourist ecosystem for long-term development in Indonesia, commercial actors must lend their full support. This study demonstrates that they can thrive when MSMEs in the halal-tourist ecosystem are backed by Islamic banking and Islamic rural banks. As a result, a more accommodating approach from Islamic banking is required to provide access to halal finance for business actors in Indonesia’s halal-tourism ecosystem.
Unpacking the Complexities of Emotional Responses to External Feedback, Internal Feedback Orientation and Emotion Regulation in Higher Education: A Qualitative Exploration
Authors: Yang Lan , Wu Yiqi , Liang Yuan , Yang Min
Published: June 2023

Research suggests that unpleasant emotions induced by feedback may reduce its efficiency in enhancing students’ performance, which is a crucial issue to address in education. In the context of Chinese language instruction in higher education, this study sought to investigate how students regulate their emotions as a result of feedback through the lens of individuals’ feedback orientation. In light of the feedback orientation lens and its conceptual framework, we applied in-depth qualitative interviews to explore how students experienced feedback, the negative emotions they experienced, and the emotion regulation strategies they used. Eleven undergraduates across years one to five joined our in-depth interviews. Students reported negative emotions when they received feedback that did not live up to their expectations or was unrealistic for them to accept. However, students’ feedback orientation supported their emotion regulation techniques, which in turn supported students’ adaptive feedback processing to interpret and take action to use feedback for academic performance improvement. Students also actively sought further teacher feedback or peer support to deal with a wide range of negative emotions. These findings imply the significance of fostering in students a high level of feedback orientation and the necessity of additional empirical investigation into the relationships between feedback orientation and emotional well-being in higher education. By shedding light on how students regulate the emotions that external feedback causes in them, the study adds valuable qualitative findings to the existing literature on positive psychology research in terms of emotions and emotion regulation. It also emphasizes how crucial students’ personal feedback orientation is for improving emotional well-being in the context of feedback.

In the current digital era, digital technologies develop and emerge rapidly, businesses, especially the electronic sector more connected to information technology, facing challenges in the terms of its technology infrastructure and tactical directions. That’s why most of them adopt the latest digital technology (DT) and design novel business strategies and models. The growing significance of AI in the transformation of manufacturing operations and the demand for a thorough knowledge of the variables affecting its adoption serve as the driving forces behind the study. Several researchers have presented that digital technology can lead toward AI adoption. Though, previous studies lack an efficient transformation pathway. Therefore, this study establishes an inventive approach and aims to investigate the direct link between digital technology and AI adoption, the mediating function of knowledge sharing (KS) between them, and explore the moderating impact of privacy and security that assist in the acceleration of AI adoption in electronics manufacturing enterprises through the antecedent of digital technology. This study is quantitative in nature, random sampling method and questionnaire is used as a survey tool. Depending on 298 questionnaire data from electronic firms of Saudi Arabia, this study performs multi-level correlation and regression analysis to evaluate study hypotheses. Findings confirm that digital technology has a positive influence on AI adoption. In addition, outcomes corroborate that knowledge sharing mediates in the linkage between digital technology and AI adoption. The results also proved that privacy and security have a positive moderation impact on the association between digital technology and AI adoption. This study enlighten that the adoption of this framework enables electronic manufacturing companies to strategically integrate digital-technologies to promote effective AI adoption, increase its operational efficiency, and sustain a competitive advantage in the constantly evolving manufacturing landscape. The outcomes as well supplement the previous study on the linkage between digital technology and AI adoption, expand application space and theoretical boundary from the perspective of knowledge sharing, privacy and security at the managerial level, and give reference for AI adoption in, as electronics manufacturing firms.

Published: June 2023

By considering the importance of water and its purity, herein, a powerful adsorbent has been developed for the adsorption of two toxic contaminants that commonly exist in water, viz., divalent mercury and hexavalent chromium. The efficient adsorbent, CNTs–PLA–Pd, was prepared by covalent grafting polylactic acid to carbon nanotubes and subsequent deposition of palladium nanoparticles. The CNTs–PLA–Pd could adsorb Hg(II), and Cr(VI) entirely exists in water. The adsorption rate for Hg(II) and Cr(VI) was rapid at initial stage, followed by gradual decrease, and attained the equilibrium. The Hg(II) and Cr(VI) adsorption was perceived within 50 min and 80 min, respectively with CNTs–PLA–Pd,. Further, experimental data for Hg(II) and Cr(VI) adsorption was analyzed, and kinetic parameters were estimated using pseudo–first and second–order models. The adsorption process of Hg(II) and Cr(VI) followed the pseudo–second–order kinetics, and the rate–limiting step in the adsorption was chemisorption. The Weber−Morris intraparticle pore diffusion model revealed that the Hg(II) and Cr(VI) adsorption over CNTs–PLA–Pd occurs through multiple phases. The experimental equilibrium parameters for the Hg(II) and Cr(VI) adsorption were estimated by Langmuir, Freundlich, and Temkin isotherms models. All three models were well suited and demonstrated that Hg(II) and Cr(VI) adsorption over CNTs–PLA–Pd transpires through monolayer molecular covering and chemisorption.

Published: June 2023

Antrocin is a novel compound isolated from Antrodia cinnamomea, and is classified as a sesquiterpene lactone. The therapeutic efficacy of antrocin has been studied, and it has shown an antiproliferative effect on various cancers. The aim of this study was to evaluate the anti-oxidant activity, potential genotoxicity, and oral toxicity of antrocin. Ames tests with five different strains of Salmonella typhimurium, chromosomal aberration tests in CHO-K1 cells, and micronucleus tests in ICR mice were conducted. The results of anti-oxidant capacity assays showed that antrocin has great anti-oxidant activity and is a moderately strong antimutagenic agent. In the results of the genotoxicity assays, antrocin did not show any mutagenic potential. In the 28-day oral toxicity test, Sprague Dawley rats were gavaged with 7.5 or 37.5 mg/kg of antrocin for 28 consecutive days. In addition, 7.5 mg/kg sorafenib, an anti-cancer drug, was used as a positive control for toxicity comparison. At the end of the study, antrocin did not produce any toxic effects according to hematology, serum chemistry, urine analysis, or histopathological examinations. According to the results of the genotoxicity and 28-day oral toxicity study, antrocin, at a dose of 37.5 mg/kg, did not cause adverse effects and can be a reference dose for therapeutic agents in humans.

Published: June 2023

The jujube is one of the most popular fruits in China because of its delicious taste and high nutritional value. It has a long history of usage as an important food or traditional medicine. However, the jujube is easily infected by fungi, which causes economic losses and threatens human health. When the jujube was infected by Aspergillus niger (H1), the changes in nutritional qualities were determined, such as the content of total acid, vitamin C, reducing sugar, etc. In addition, the ability of A. niger (H1) to produce ochratoxin A (OTA) in different inoculation times and culture media was evaluated, and the content of OTA in jujubes was also analyzed. After jujubes were infected by A. niger (H1), the total acid, and vitamin C contents increased, while the total phenol content decreased, and the reducing sugar content increased after an initial decrease. Although A. niger (H1) infection caused the jujubes to rot and affected its quality, OTA had not been detected. This research provides a theoretical foundation for maximizing edible safety and evaluating the losses caused by fungal disease in jujubes.

High pathogenicity avian influenza (HPAI) viruses of clade 2.3.4.4 H5Nx have been circulating in poultry and wild birds worldwide since 2014. In South Korea, after the first clade 2.3.4.4b H5N1 HPAI viruses were isolated from wild birds in October 2021, additional HPAIV outbreaks occurred in poultry farms until April 2022. In this study, we genetically characterized clade 2.3.4.4b H5N1 HPAIV isolates in 2021–2022 and examined the pathogenicity and transmissibility of A/mandarin duck/Korea/WA585/2021 (H5N1) (WA585/21) in chickens and ducks. Clade 2.3.4.4b H5N1 HPAI viruses caused 47 outbreaks in poultry farms and were also detected in multiple wild birds. Phylogenetic analysis of HA and NA genes indicated that Korean H5N1 HPAI isolates were closely related to Eurasian viruses isolated in 2021–2022. Four distinct genotypes of H5N1 HPAI viruses were identified in poultry, and the majority were also found in wild birds. WA585/21 inoculated chickens showed virulent pathogenicity with high mortality and transmission. Meanwhile, ducks infected with the virus showed no mortality but exhibited high rates of transmission and longer viral shedding than chickens, suggesting that they may play an important role as silent carriers. In conclusion, consideration of both genetic and pathogenic traits of H5N1 HPAI viruses is required for effective viral control.

Dog-mediated rabies is endemic in much of Indonesia, including Bali. Most dogs in Bali are free-roaming and often inaccessible for parenteral vaccination without special effort. Oral rabies vaccination (ORV) is considered a promising alternative to increase vaccination coverage in these dogs. This study assessed immunogenicity in local dogs in Bali after oral administration of the highly attenuated third-generation rabies virus vaccine strain SPBN GASGAS. Dogs received the oral rabies vaccine either directly or by being offered an egg-flavored bait that contained a vaccine-loaded sachet. The humoral immune response was then compared with two further groups of dogs: a group that received a parenteral inactivated rabies vaccine and an unvaccinated control group. The animals were bled prior to vaccination and between 27 and 32 days after vaccination. The blood samples were tested for the presence of virus-binding antibodies using ELISA. The seroconversion rate in the three groups of vaccinated dogs did not differ significantly: bait: 88.9%; direct-oral: 94.1%; parenteral: 90.9%; control: 0%. There was no significant quantitative difference in the level of antibodies between orally and parenterally vaccinated dogs. This study confirms that SPBN GASGAS is capable of inducing an adequate immune response comparable to a parenteral vaccine under field conditions in Indonesia.

Published: June 2023

Human papillomavirus (HPV) vaccination protects against six types of cancer—cervical, anal, oropharyngeal, penile, vulvar, and vaginal. In the United States (U.S.), HPV vaccination coverage in college students remains low, especially in the Mid-South region, despite the highest risk of HPV infections and disease burden. However, few studies have assessed HPV vaccination among college students here. This study examined factors associated with HPV vaccination among college students in the Mid-South and explored preferred strategies for promoting vaccination. A mixed-methods design comprising a cross-sectional, self-report online survey and dyadic virtual interviews was conducted. Simple random sampling was performed to recruit a total of 417 undergraduate students aged 18–26 from March to May 2021; convenience sampling was performed to recruit three sex-matched dyads of a total of six (four female and two male) undergraduates from survey respondents who had not completed the HPV vaccine series in May 2021. Binary logistic regression analyses showed HPV vaccine knowledge and perceived barriers to vaccination were factors contributing to coverage for both female and male students, while perceived risks of HPV and vaccine hesitancy were factors only among female students. Findings from the qualitative content analysis identified college students’ perceived barriers to the vaccination at multiple levels and preferred strategies for vaccination promotion, corroborating the findings from the survey study. The findings provide implications that benefit the development of tailored interventions aimed at facilitating catch-up vaccination among college students in the Mid-South region. There is an urgent need for further research and the implementation of effective strategies that address the identified barriers and improve HPV vaccine uptake in this population.

The University of Texas MD Anderson Cancer Center, a comprehensive cancer center designated by the National Cancer Institute (NCI), defines its service population area as the State of Texas (29.1 M), the second most populous state in the country and the state with the greatest number of uninsured residents in the United States. Consistent with a novel and formal commitment to prevention as part of its core mission, alongside clear opportunities in Texas to drive vaccine uptake, MD Anderson assembled a transdisciplinary team to develop an institutional Framework to increase adolescent HPV vaccination and reduce HPV-related cancer burden. The Framework was developed and activated through a four-phase approach aligned with the NCI Cancer Center Support Grant Community Outreach and Engagement component. MD Anderson identified collaborators through data-driven outreach and constructed a portfolio of collaborative multi-sector initiatives through review processes designed to assess readiness, impact and sustainability. The result is an implementation community of 78 institutions collaboratively implementing 12 initiatives within a shared measurement framework impacting 18 counties. This paper describes a structured and rigorous process to set up the implementation of a multi-year investment in evidence-based strategies to increase HPV vaccination that solves challenges preventing implementation of recommended strategies and to encourage similar initiative replication.

Leishmaniasis is a wide-spectrum disease caused by parasites from Leishmania genus. A well-modulated immune response that is established after the long-lasting clinical cure of leishmaniasis can represent a standard requirement for a vaccine. Previous studies demonstrated that Leishmania (Viannia) naiffi causes benign disease and its antigens induce well-modulated immune responses in vitro. In this work we aimed to identify the immunodominant proteins present in the soluble extract of L. naiffi (sLnAg) as candidates for composing a pan-specific anti-leishmaniasis vaccine. After immunoblotting using cured patients of cutaneous leishmaniasis sera and proteomics approaches, we identified a group of antigenic proteins from the sLnAg. In silico analyses allowed us to select mildly similar proteins to the host; in addition, we evaluated the binding potential and degree of promiscuity of the protein epitopes to HLA molecules and to B-cell receptors. We selected 24 immunodominant proteins from a sub-proteome with 328 proteins. Homology analysis allowed the identification of 13 proteins with the most orthologues among seven Leishmania species. This work demonstrated the potential of these proteins as promising vaccine targets capable of inducing humoral and cellular pan-specific immune responses in humans, which may in the future contribute to the control of leishmaniasis.
Characterising Rhythmic and Episodic Pulsing Behaviour in the Castleton Karst, Derbyshire (UK), Using High Resolution in-Cave Monitoring
Authors: Gunn John , Bradley Chris
Published: June 2023

The discharge from most karst springs exhibits a consistent and reasonably predictable response to recharge but a few exhibit short-term (‘rhythmic’) changes in flow that are commonly attributed to the geometry of feeder conduits and the action of siphons. This paper investigates water flow in a karst system that exhibits rhythmic and episodic changes in discharge due to variations in flow from two phreatic conduits (Main Rising (MR) and Whirlpool Rising (WR)) that pass through Speedwell Cavern en route to the springs. Water tracing experiments indicate that the conduits receive both allogenic and autogenic recharge. Flow dynamics and conduit behaviour were investigated using high-resolution (2-min) water depth data collected from MR and WR between 2012 and 2015 (when MR was dominant) and between 2021 and 2023 (when WR was dominant). Water depths were also logged in a cave at the upstream end of a conduit draining to both MR and WR and at springs. The short-term temporal variability in water depths at both MR and WR is greater than any documented in previous studies. This is attributed to conduit bedrock geometry and changes in conduit permeability due to sediment accumulation in phreatic loops, which together influence the response to recharge.
The Current Status of Forest Residues and Disposal Machinery in Turkiye
Authors: Gülci Sercan , Sarıyıldız Temel , Akay Abdullah Emin
Published: June 2023

The term "cutting residue" is a widely used term in Turkey, which refers to the leftover pieces of logs in the forest after cutting, except for the logs. As of yet, there is no specific expression and explanation for the term "slash" in Turkish forestry. Turkey carries out intensive forestry activities based on industrial wood production, primarily in mature stands and damaged after disasters such as fire or storm fall. Products that do not carry industrial woodiness in the stand, such as branches, roots, and tips that are not suitable for industrial production, are considered firewood and used for energy production or left in the stand. As a result, it is observed that the collected cutting residues from the fields that are sufficient in terms of benefit and cost is burned to generate electricity in electricity generation stations. Due to the demand for forest-based wood raw materials in recent years, some domestic companies have begun converting thick branches into industrial products such as paper and chipboard production. Additionally, some studies have been conducted to reduce transportation costs in bringing cutting residues to the economy, focusing on the storage and processing of forest cutting residues on the landing sites. In this regard, small-scale chipping machines have been produced by the domestic industry. Therefore, slash disposal and mechanization have a very limited place in Turkish forestry. Decision makers need to prepare action plans in this regard and provide support to joint research projects with academic units.
Estimating effective acoustic properties of various configuration of perforated panels
Authors: Dandsena J.
Published: June 2023

Acoustic metamaterial attains uncommon material properties over natural material such as negative effective mass density, negative effective bulk modulus, or both. To start with, the present research demonstrates and establishes robust method to estimate and measure acoustic metamaterial
properties of a Helmholtz resonator analytically using transfer matrix (TM) method and experimentally in detail. The proposed method extracts the reflection and transmission coefficients from corresponding TM to evaluate the effective acoustic metamaterial properties. For a single Helmholtz
resonator, the effective bulk modulus has been observed negative; however, the effective density remains positive. In order to attain double negative material properties, the perforated panel (PP) and microperforated panel (MPP) have been introduced in parallel to resonator. The 1D electro-acoustic
modeling has been carried out for all configurations to estimate effective properties analytically. Successively, the experiments have been conducted to measure the effective properties from acoustic metamaterial prospective. The analytical and experimental investigations on five different
cases reveal that one can attain negative effective compressibility and effective density by cascading two PPs or MPPs with a finite duct. Moreover, by backing a Helmholtz resonator from both sides with two PPs or MPPs in parallel, one can attain double negative properties comparatively higher
than earlier configuration in low-frequency zone in broadband. In total, eight different configurations have been investigated analytically and experimentally, where it has been demonstrated that the proposed compact model is more effective than a finite array of same Helmholtz resonators.
Bilan du programme OURSALP. Exemple de l’ours fossile du scialet de la décroissance à Corrençon-en-Vercors (Isère, France)

Published: June 2023

Le Programme OURSALP existe depuis 2002 avec comme objectifs de constituer un inventaire des ours fossiles ou subfossiles, de constituer un cadre chronologique rigoureux de datations 14C-AMS sur vestiges d’ours, de préciser les paléoenvironnements et les exigences écologiques des différentes espèces, de rechercher les interactions homme -ours, enfin d’instaurer une collaboration étroite entre spéléologues et scientifiques. Le bilan actuel montre que l’ours des cavernes (Ursus spelaeus) est présent au moins depuis 45 000 ans BP et sans doute bien avant. Il s’éteint en Chartreuse à la fin du Tardiglaciaire, au cours de la période froide du Dryas ancien, plus tard apparemment que dans le reste de l’arc alpin. Le Massif de Chartreuse a donc joué le rôle d’un refuge. L’homme préhistorique n’est pas la cause de l’extinction d’Ursus spelaeus, les conditions climatiques ont joué un rôle déterminant. L’ours brun du Scialet de la Décroissance à Corrençon-en-Vercors (Isère), gisait au fond d’un puits de 30 m. Ce squelette complet, à quelques perturbations près, permet une étude détaillée d’un même individu : sexe, taille, taphonomie, datation 14 C-AMS, ADN-mt ancien, c’est assez rare pour être souligné. L’ours brun, Ursus arctos, traverse la fin du Tardiglaciaire et l’amélioration climatique holocène. Il est plus carnivore que l’ours des cavernes et mieux adapté à la chaleur. Sa disparition du Jura et des Alpes françaises aux temps historiques est évidemment liée à l’action humaine, pression de chasse liée au développement des armes à feu et disparition des biotopes favorables. Le site de la Grande Rivoire apporte l’indication de l’apprivoisement d’un ours brun ayant vécu au contact des Castelnoviens, il y a 7700 ans, muni d’un mors selon la technique des montreurs d’ours.
L’industrie en matières osseuses du site du Pas de l’Échelle (Rovon, Isère)
Authors: Marquebielle Benjamin
Published: June 2023

Le site du Pas de l’Échelle a livré une petite collection d’industrie en matières osseuses, principalement des pièces en bois de cerf. Seule l’exploitation de cette matière première est attestée durant les occupations datées de l’âge du Bronze. Dans les niveaux du Néolithique, ont été retrouvées des pièces en bois de cerf ainsi qu’une pièce en os. Les témoins du travail des matières osseuses mis au jour au Pas de l’Échelle sont relativement ubiquistes, avec néanmoins quelques traits plus caractéristiques, techniques ou morphologiques, au sein de chaque ensemble chronologique.

Situé à 980 m d’altitude sur la façade ouest du Vercors, ce site se trouve sur un passage naturel reliant la plaine de l’Isère à un important axe de circulation nord-sud donnant accès aux Hauts-Plateaux du Vercors et plus loin au bassin de la Drôme. Le Pas de l’Échelle a livré une stratigraphie de 4 m de hauteur comportant des niveaux archéologiques du Premier et du Second Mésolithique, du Néolithique ancien et moyen, du Bronze ancien et final, de l’âge du Fer et enfin de l’Antiquité tardive. Dans l’ensemble bien préservés des perturbations post-dépositionnelles, ces niveaux, qui correspondent à de courtes occupations humaines, ont été calés chronologiquement par 13 datations radiocarbones cohérentes entre elles. Cet article traite particulièrement des occupations du Mésolithique et de la question de la transition Méso-Néolithique. La comparaison avec les sites mésolithiques et de la transition néolithique du Vercors permet de mieux appréhender la fonction du site dans l’exploitation territoriale par les hommes. La question des ensembles mixtes Méso-Néolithiques sur une plage chronologique entre 6200 et 5400 Cal. BC est évoquée. Au Pas de l’Échelle, un tel ensemble est en effet en rupture sur le plan paléoenvironnemental tout comme dans la composition des industries lithiques, avec le Second Mésolithique sous-jacent.

Enfin la séquence du Pas de l’Échelle est replacée dans un contexte régional qui regroupe six séquences stratigraphiques issues

de gisements majeurs des Alpes du Nord et qui ont livré des niveaux d’occupations humaines s’échelonnant du Dryas ancien au Subboréal.

L’Abri Faravel, découvert en 2010 à 2 133 m d’altitude dans le Parc National des Écrins (Freissinières, Hautes-Alpes, France), est un site d’altitude ayant fait l’objet de plusieurs campagnes de fouille programmée entre 2011 et 2015. Cet abri-sous-roche a connu plusieurs phases d’occupation sur une longue durée, depuis le Mésolithique jusqu’à l’époque contemporaine. Le mobilier archéologique collecté lors de ces fouilles se compose d’une série lithique assez importante dans un tel contexte (plus de 3 000 objets enregistrés dont un lot important de pièces diagnostiques attribuables au Premier Mésolithique) mais aussi, en moindre quantité, de céramique non tournée de l’âge du Fer, d’un objet de parure antique et d’éléments de ferronnerie antiques et médiévaux. La présence de peintures rupestres, comportant notamment la figuration de quadrupèdes la plus haute d’Europe à ce jour, souligne l’originalité de cet abri. La technique et le thème (un cerf blessé affronté à un autre animal) des peintures schématiques réalisées à l’ocre sur le plafond de l’abri et sur la paroi du fond, mais également les associations présentes, invitent à les attribuer au Néolithique. L’étude de ce site s’inscrit dans le cadre des recherches pluridisciplinaires menées depuis plusieurs années, sous la direction de F. Mocci et K. Walsh, dans les hauts massifs de l’Argentiérois, au coeur du Parc National des Écrins. Ces dernières ont notamment mis en évidence la fréquentation par l’Homme de ces reliefs alpins, au-delà de 2 000 m d’altitude, dès le Mésolithique. Nous présentons dans cet article un état des connaissances relatives à cet abri que nous replaçons dans le contexte plus large des données archéologiques et environnementales établi dans ce secteur des Alpes méridionales françaises.
La grotte de Prélétang (Presles, Isère) : un camp de chasse moustérien de moyenne montagne

Published: June 2023

La grotte de Prélétang, localisée dans le massif des Coulmes, dans le Vercors, à 1 225 m d’altitude, s’ouvre dans les calcaires urgoniens. Des fouilles, effectuées au niveau du porche et du seuil de la cavité, entre 1994 et 1999, par une équipe dirigée par T. Tillet, ont permis de mettre au jour une couche moustérienne. Ce niveau, daté de 46 200 ± 1 500 BP (OXA-10260, Ly-1382), a en partie été remaniée par des phénomènes de ruissellements, de charriages à sec et d’effondrements karstiques, surtout au niveau du seuil de la grotte. La faune recueillie dans cette couche moustérienne est peu abondante et très fragmentée. La marmotte et l’ours des cavernes y sont bien représentés mais leur présence est certainement naturelle. En revanche, les Néandertaliens ont dû introduire dans le site les différentes espèces d’Ongulés identifiées : cerf, chevreuil, sanglier, bouquetin et aurochs, comme l’attestent quelques os qui présentent des traces liées à une activité de boucherie ou des traces de combustion. L’industrie lithique, composée d’environ 300 pièces, est dominée par les produits Levallois et les outils à bords convergents. Les racloirs simples sont également abondants. La rareté des nucléus et des produits corticaux indiquent que le débitage a eu lieu à l’extérieur du site, probablement sur les gites de matières premières, distants de 7 km et à plus de 20 km. Le gisement moustérien de Prélétang a été le siège d’un ou de plusieurs campements de courtes durées en relation avec une exploitation cynégétique du plateau des Coulmes.

L’abri du Pas de l’Échelle à Rovon a été occupé à la fin du Néolithique, à l’âge du Bronze ancien et au Bronze final 1 et 2. Le mobilier céramique présenté n’est significatif que pour le Bronze moyen-Bronze final 1. Les comparaisons conduisent vers la vallée du Rhône et vers les productions du style à cannelures au début du Bronze final, attribution confirmée par une date radiocarbone. Les occupations de l’âge du Bronze correspondent à des passages, des fréquentations ou des occupations très sporadiques de l’abri, discontinues, un peu plus durables, peut être dès la fin du Bronze moyen et certainement pour le BF1. Elles pourraient être liées à des déplacements depuis la vallée, dans le cadre de parcours pastoraux gagnant les pâturages du Vercors par l’emprunt d’un des accès privilégiés au plateau. Les phases représentées dans l’abri du Pas de l’Échelle, synchrones d’améliorations des conditions climatiques, sont aussi attestées par le développement de l’habitat en plaine et sur les reliefs, lors de renouveaux des dynamiques de peuplement à vocation agro-pastorale à large échelle.

Published: June 2023

The mounds of Combe Bossue were discovered in 2014 during the fortuitous discovery of an assembly of seven bronze bracelets

attributable to Hallstatt D1. A first intervention in 2015 followed by a second the following year made it possible to unearth an

unprecedented protohistoric burial ensemble on the Vercors plateau. Two contiguous burial mounds were erected before the 6th century BC and probably served as a receptacle for as many burials whose soil acidity did not allow conservation. The rare regional comparisons concerning the architecture of these tumuli make it possible to propose a chronological attribution centered on the Bronze A and / or B. Subsequently a burial, probably feminine, was deposited on the eastern border of the two tumuli. In spite of its very poor state of preservation, the metal assemblage associated with the burial make it possible to associate it with the series of abundant adornment of female burials, characteristic of the Hallstatt D1-D2.

Published: June 2023

Key Points

Serum uromodulin levels are higher in healthy female participants than healthy male participants.

Serum uromodulin levels in participants with normal kidney function do not correlate with eGFR but do correlate with body mass index.

Estrogen increases uromodulin production, likely because of noncanonical and half estrogen response elements in the UMOD gene.

The oxygen octahedral rotation (OOR) forms fundamental atomic distortions and symmetries in perovskite oxides and definitely determines their properties and functionalities. Therefore, epitaxial strain and interfacial structural coupling engineering have been developed to modulate the OOR patterns and explore novel properties, but it is difficult to distinguish the 2 mechanisms. Here, different symmetries are induced in Na

Moreover, the interfacial oxygen octahedral coupling effect is demonstrated to propagate to the entire thickness of the film, suggesting an intriguing long-range effect. This work provides a deep insight into understanding the structure modulation in perovskite heterostructures and an important avenue for achieving unique functionalities.

Purpose: to determine the comparative analysis of disorders of the musculoskeletal system and the level of stress of students of sports faculties in Indonesia and Malaysia.

Material and methods. 316 students of the Faculty of Sports Science of Indonesia and Malaysia were sampled from this study: 159 students of the Faculty of Sports Science of Indonesia, and 157 students of Sports Science of Malaysia. This research is a comparative analytical observational descriptive study conducted with a cross-sectional approach. This research was conducted in several universities both in Indonesia and Malaysia. The subjects of this study were students from Indonesia and Malaysia who took part in online learning by the criteria of inclusion and exclusion. The instrument used to collect data was a questionnaire for musculoskeletal disorders using a Nordic Body Map while a stress level questionnaire used an MSSQ (Medical Student Stressor Questionnaire). Data analysis techniques use descriptive tests through percentage distribution and comparison tests.

The results. Based on the results of the Independent Sample t-test, a calculated t-value of 4.076 with a significance value of 0.000 was obtained. Because the significance value of 0.000 is smaller than 0.05 (p<0.05), it can be concluded that there is a significant difference in musculoskeletal disorders between Indonesian and Malaysian students. The most common musculoskeletal disorder experienced by Malaysian students is a disorder of the lower back with an average of 3.15. Based on the results of the Independent Sample t-test analysis, a calculated t-value of 3.624 with a significance value of 0.000 was obtained. Because the significance value of 0.000 is less than 0.05 (p<0.05), it can be concluded that there is a significant difference in stress levels between Indonesian and Malaysian students. Based on the results of the analysis, the average value of stress levels in Indonesian students was 15.66 while the average value of stress levels in Malaysian students was 17.77. It can be interpreted that students from Malaysia have a higher level of stress compared to Indonesian students.

Conclusions. Based on the results of the study, it can be concluded that: Malaysian students experience higher musculoskeletal disorders in the lower back and high-stress levels due to online learning compared to Indonesian students.

Purpose. Running is a common sport and recreational activity in the United States. Due to its dysfunctional implication in runners, femoroacetabular impingement (FAI) is increasingly recognized as a problematic source of anterior hip pain. The purpose of this case series was to describe an impairment-based physical therapy intervention in non-professional runners with FAI.

Materials and methods. Two males, non-professional runners with a mean age of 28.5± 2.1 years, both with a diagnosis of femoroacetabular impingement (FAI), were treated with manual therapy, dynamic neuromuscular stabilization (DNS), and functional training. At initial evaluation, subjects were examined and completed self-reported outcome measures including the visual analog scale (VAS), and the patient-specific functional scale (PSFS). At discharge, they completed the same outcome measures along with the global rating of change (GROC) questionnaire.

Results. Both subjects showed clinically meaningful improvement in pain and function above the minimal clinically important difference (MCID). Upon discharge, subject 1 had a 86% reduction in VAS score, a 75% improvement in PSFS score, and a GROC score of 6; subject 2 had a 88% reduction in VAS, a 64% improvement in PSFS, and a GROC score of 5.

Conclusion. The overall improvement observed in this study was clinically meaningful to subjects who participated, however, because a cause and effect cannot be inferred from case series studies, follow-up randomized clinical/controlled trials are recommended to further investigate the studied intervention on runners with FAI.

The effects of gastrointestinal parasties on feed intake and growth is well-established. The emphasis here is on raising awareness that parasites do have effects on body compositon and meat quality atrributes. Body composition refers to the acceptable balance of lean to fat ratio when animals were parasitised or when they were free of parasites. Rejection of carcases due to parasitism is also covered. It was concluded that parasitic infections at subclinical level lead to reduced quantity and impaired quality of meat indirectly by in protein and energy intake as well as through altering and diverting of protein availability for both body maintenance in the forms of establishing resilience to infection as well as repairing of tissues damaged by parasites at sites of predilection. Ineficiency in meat production and alterations to body composition due to nematode parasitism is very much associated with alterations in nutrient absorption and utilisation.

Penggunaan jagung sebagai pakan harus memenuhi standar kualitas kimia yang dipersyaratkan untuk menjamin keamanan pakan. Penggunaan penghambat jamur sintetis merupakan salah satu strategi untuk menghambat pertumbuhan jamur dan produksi metabolit sekunder yang dapat menurunkan kualitas kimia jagung. Penelitian ini bertujuan untuk menganalisis kandungan amilum (pati) dan aflatoksin B1 (AFB1) jagung kuning pipilan yang terdiri dari tiga level kadar air dan disuplementasi produk anti jamur sintetis. Sejumlah 750 kg jagung kuning pipilan digunakan dalam penelitian ini. Penghambat jamur (PJ) komersial yang digunakan diperoleh dari PT Japfa Comfeed Tbk, Indonesia dengan dosis 450 g/ton jagung. Percobaan dua faktor (Level kadar air: 13, 14 dan 15%; penghambat jamur PJ: -, +) digunakan pada penelitian ini.  Hasil uji ANOVA membuktikan bahwa kecuali kandungan pati, interaksi yang signifikan antara LKA dan PJ terhadap kandungan aflatoksin B1 jagung yang disimpan selama 60 hari. Jagung (LKA berbeda dan tanpa PJ) memiliki kandungan AFB1 lebih tinggi dari yang diberi PJ.  Simpulannya, penggunaan penghambat jamur efektif menghambat pertumbuhan jamur sehingga produksi aflatoksin B1 dapat ditekan. Penggunaan PJ sintetis tidak mempengaruhi kandungan pati jagung biji selama 60 hari penyimpanan.
