Spectroscopic Characterization of Diazophosphane—A Candidate for Astrophysical Observations
Authors: Tschöpe Martin , Rauhut Guntram
Published: May 2023

Quite recently, diazophosphane, HP−N≡N, was synthesized for the first time. This was accomplished by a reaction of PH3 with N2 under UV irradiation at 193 nm. As these two molecules have been observed in different astrophysical environments, as for example, in the circumstellar medium and, in particular, in the AGB star envelope IRC+10216, the question arises whether HPN2 can be found as well. So far there is only the aforementioned experimental work, but neither rotational nor rovibrational data are available. Hence, the lack of accurate line lists, etc. to identify diazophosphane is the subject of this work, including a detailed analysis of the rotational, vibrational, and rovibrational properties for this molecule. Our calculations rely on multidimensional potential energy surfaces obtained from explicitly correlated coupled-cluster theory. The (ro)vibrational calculations are based on related configuration interaction theories avoiding the need for any model Hamiltonians. The rotational spectrum is studied between T = 10 and 300 K. In contrast, the partition functions for HPN2 and DPN2 are given and compared for temperatures up to 800 K. In addition, more than 70 vibrational transitions are calculated and analyzed with respect to resonances. All these vibrational states are considered within the subsequent rovibrational calculations. This allows for a detailed investigation of the infrared spectrum up to 2700 cm−1 including rovibrational couplings and hot bands. The results of this study serve as a reference and allow, for the first time, for the identification of diazophosphane, for example, in one of the astrophysical environments mentioned above.
Generating Space-based SDO/HMI-like Solar Magnetograms from Ground-based Hα Images by Deep Learning
Authors: Gao Fei , Liu Tie , Sun WenQing , Xu Long
Published: May 2023

Recently, the method of estimating magnetic field through monochromatic images by deep learning has been proposed, demonstrating good morphological similarity but somewhat poor magnetic polarity consistency relative to real observation. In this paper, we propose to estimate magnetic field from Hα images by using a conditional generative adversarial network (cGAN) as the basic framework. The Hα images from the Global Oscillation Network Group are used as the inputs and the line-of-sight magnetograms of the Helioseismic Magnetic Imager (HMI) are used as the targets. First, we train a cGAN model (Model A) with shuffling training data. However, the estimated magnetic polarities are not very consistent with real observations. Second, to improve the accuracy of estimated magnetic polarities, we train a cGAN model (Model B) with the chronological Hα and HMI images, which can implicitly exploit the magnetic polarity constraint of time-series observation to generate more accurate magnetic polarities. We compare the generated magnetograms with the target HMI magnetograms to evaluate the two models. It can be observed that Model B has better magnetic polarity consistency than Model A. To quantitatively measure this consistency, we propose a new metric called pixel-to-pixel polarity accuracy (PPA). With respect to PPA, Model B is superior to Model A. This work gives us an insight that the time-series constraint can be implicitly exploited through organizing training data chronologically, and this conclusion also can be applied to other similar tasks related to time-series data.
Association between eupatilin and reduction in small bowel bleeding in aspirin users and aspirin plus acid suppressant users
Authors: Lee Hyun Seok , Nam Ji Hyung , Oh Dong Jun , Ahn Hyun Jung , Lim Yun Jeong
Published: May 2023

Background/Aims: Capsule endoscopy (CE) has shown that low-dose aspirin occasionally causes small bowel (SB) bleeding. We herein evaluated the protective effects of mucoprotective agents (MPAs) on SB bleeding in aspirin users using the nationwide database of claims data from the National Health Insurance Service (NHIS).Methods: As CE is an insured procedure, we constructed an aspirin-SB cohort using NHIS claims data, with a maximum follow- up period of 24 months. Patients with anemia, melena, or hematochezia that occurred within 4 weeks before and after performing CE were suspected to have SB bleeding. A Cox proportional hazards regression model was used to determine the risk factors for SB bleeding. Subgroup analyses were conducted among patients who used acid suppressants, such as proton pump inhibitors (PPIs) and histamine-2 receptor antagonists.Results: A total of 15,542 aspirin users were included. Anticoagulant use (hazard ratio [HR], 3.22), high Charlson comorbidity index score (≥ 2) (HR, 3.54), and PPI use (HR, 2.85) were significantly associated with SB bleeding, whereas eupatilin use (HR, 0.35) was a preventive factor. SB bleeding occurred more frequently in concurrent users of acid suppressants than in nonusers (1.3% vs. 0.5%). Subgroup analysis revealed that eupatilin significantly reduced the risk of SB bleeding in aspirin users with concurrent use of acid suppressants (HR, 0.23 vs. 2.55).Conclusions: Eupatilin was associated with a reduced risk of SB bleeding in both aspirin users and those with concomitant use of acid suppressants. Eupatilin use should be considered for aspirin users, especially for those concomitantly taking acid suppressants.
Le sanctuaire gallo-romain à édifices multiples des Hernies à Macé (Orne)
Authors: Leclerc Guy , Leclerc Guy
Published: May 2023

À 3,5 km au nord-ouest de Sées, chef-lieu de cité des Sagii , le sanctuaire des Hernies a fait l’objet d’une fouille programmée de 2005 à 2007. Une première phase d’occupation, datable du début de la période augustéenne, est matérialisée par un simple bâtiment quadrangulaire doté d’un foyer central associé à une construction à plan centré. La phase monumentale d’aménagement intervient sous les règnes de Caligula ou Claude, avec la construction d’un second bâtiment carré entouré d’une galerie et de neuf édicules carrés placés dans plusieurs cours circonscrites par un péribole maçonné. Les pratiques cérémonielles consistent en sacrifices d’animaux et dépôts d’offrandes : monnaies, éléments de parures, statuettes en terre cuite, céramiques et objets domestiques. Dans la seconde moitié du iii e siècle, le démantèlement partiel des structures est perceptible. Un réaménagement d’une partie du site intervient au début du iv e siècle avec la réutilisation de plusieurs édicules, l’édification de cabanes et la construction d’un nouvel édifice.

Published: May 2023

La dynamique des réseaux d’échanges et la production de terre cuite dans l’ouest de la France, et plus particulièrement en Normandie occidentale, ont été appréhendées dans de nombreux habitats grâce à la multiplication des découvertes de corpus céramiques antiques au cours de ces dernières décennies. Aux côtés des importations lointaines de vaisselle, de nombreuses productions locales et régionales ont été mises en évidence par la récurrence de certaines formes au sein des répertoires et de groupes de pâte observés à l’œil nu ou à la loupe binoculaire. Afin de circonscrire et d’identifier plusieurs aires probables de productions, une démarche d’analyses collaboratives a été mise en œuvre. Elle s’appuie sur le croisement des données typo-chronologiques avec des analyses pétro-graphiques et chimiques réalisées sur les produits finis et sur différents matériaux argileux susceptibles d’être utilisés pour l’artisanat potier. Les productions des ateliers de Lisieux et de Sées ont également été réexami-nées afin de préciser leur spécificité sous les angles typologique et physi-co-chimique, tout en proposant de nouvelles données sur leur chronologie et aire de diffusion.
Les supports de vase gallo-romains de Normandie occidentale. Éléments vernaculaires de la culture matérielle régionale
Authors: Demarest Mélanie , Lėon Gaël
Published: May 2023

Les supports de vase, généralement retrouvés en petit nombre, bénéficient rarement d’une présentation synthétique à l’échelle d’une région. L’inventaire des supports de vase antiques permet de recenser 81 exemplaires en Nor-mandie occidentale. Il s’agit de productions locales assez répandues au sein de ce territoire qui témoignent d’une corrélation forte entre ressources naturelles et production. Si la fonction de support semble attestée pour les exemplaires normands, leur usage précis selon la nature du vase associé reste encore en suspens.
Production et circulation des meules rotatives antiques le long de la Manche : perspectives de recherche en Normandie
Authors: Picavet Paul
Published: May 2023

Au xix e siècle, Charles de Gerville mentionnait des carrières de meules romaines sur la pointe du Cotentin ; Léon de La Sicotière découvrait de possibles ateliers de taille de meules à Alençon. Aujourd’hui, à la faveur d’une dynamique nationale renouvelée, les études de meules se multiplient et éclairent un pan méconnu de l’économie antique. La présence du poudingue à galets de silex tertiaire est prédominante le long de la Manche, au moins du Cotentin au Pas-de-Calais ; on le retrouve dans le sud de l’Angleterre, ce qui révèle certains contacts transmanche dès l’âge du fer et tout au long de l’Antiquité. Parallèlement à ces productions normandes très caractéristiques, certaines roches sédimentaires et plutoniques montrent des variations pétrographiques qui révèlent un approvisionnement meulier complexe à l’ouest de la Normandie. Des études récentes ont mis en évidence des éléments dont l’origine géologique est à rechercher en bordure du Massif armoricain, dans le Cotentin et dans les massifs granitiques de Vire et d’Athis.
Quand le silence s’installe… Quelques expériences d’un clinicien
Authors: Marcelli Daniel
Published: May 2023

En présence de certaines situations cliniques, le thérapeute éprouve une perplexité, un sentiment de ne rien y comprendre alors même que l’entretien ou les séances se déroulent sans heurt apparent. Ce silence associatif, ce blanc dans la pensée, reflète en lui un silence, une énigme dans l’histoire du patient et de sa famille, trace intangible autour de laquelle pivote la dynamique relationnelle. Il faut que le clinicien puisse souffrir d’attendre ( « suffere » en latin signifie « attendre ») pour qu’au moment propice la parole du patient ou de ses proches puisse dévoiler le sens de ce silence et de cette souffrance familiale… Quatre courtes vignettes en sont l’illustration.
Risques sanitaires : anticiper pour mieux gérer
Authors: Znaty Sylvie , Dab William , Jean Kévin
Published: May 2023

Après la crise sanitaire de 2020-2021, l’association Futuribles International a mis en place, en 2022, un forum prospectif Santé 2040 incluant notamment des travaux sur les relations entre santé et environnement 1 . En écho à ces travaux, la revue Futuribles publie, dans ce numéro, un article de Sylvie Znaty, William Dab et Kévin Jean sur la prise en compte des risques sanitaires, leur nature et la nécessité de mieux les anticiper dans les organisations, publiques comme privées. On a malheureusement, en France comme ailleurs, fait l’expérience de ce que pouvait coûter (au sens large : humain, économique, politique…) une crise sanitaire, et l’on mesure désormais l’importance de l’anticipation des risques et de la prévention en matière de santé. Mais concrètement, comment faire et surtout comment bien faire ? Après un rappel de ce que recouvre la gestion des risques sanitaires, cet article décrit en quoi peut consister une politique en la matière et les outils sur lesquels elle doit s’appuyer : principes directeurs, cartographie des risques, etc. — des éléments essentiels mais susceptibles de varier selon le point de vue adopté (épidémiologiste, entrepreneur, juriste…). Les auteurs soulignent également la différence d’appréhension des problématiques de santé suivant le pays considéré — on ne court pas les mêmes risques dans les pays du Sud que dans ceux du Nord, dans une région industrielle que dans une région agricole… Qui plus est, les risques sanitaires que l’on rencontre aujourd’hui sont très souvent plurifactoriels, ce qui complique encore leur anticipation et leur prévention en raison de la diversité des acteurs concernés. En raison de ces différents éléments et pour tenir compte de l’environnement, qui constitue lui aussi un élément majeur dans les conditions d’exposition au(x) risque(s) d’une population, les auteurs invitent à adopter une approche prospective intégrée, résolument intersectorielle, afin d’élaborer des scénarios de gestion des risques. Ils terminent par une réflexion sur les enjeux du principe de précaution, dans le cadre institutionnel de la France, avec en ligne de mire : informer, rassurer, protéger des citoyens très (trop ?) (parfois mal) informés… S.D. 1 Présenté sur la page https://www.futuribles.com/folder/forum-prospectif-sante-2040/
Le mirage des classes moyennes en Afrique
Authors: Lautier Marc
Published: May 2023

Le contexte inflationniste qui pèse sur l’économie mondiale depuis plus d’un an, lié aux conséquences de la guerre engagée par la Russie en Ukraine, met à mal le pouvoir d’achat d’une partie importante des consommateurs, en Europe comme ailleurs. Les premiers touchés par cette situation sont, bien évidemment, les ménages à bas revenus et issus de la classe moyenne, qui peuvent rapidement basculer dans la pauvreté. Si ceci vaut dans les pays développés, c’est encore plus prégnant dans les pays en développement, à commencer par ceux du continent africain dont la croissance économique mise beaucoup sur l’essor des classes moyennes. Or, sans même tenir compte des évolutions récentes ayant suivi la crise Covid et le conflit en Ukraine, cette émergence des classes moyennes en Afrique reste très hypothétique, comme le montre ici Marc Lautier. Après un bref rappel de la situation économique en Afrique subsaharienne, principal gisement mondial de population active, actuel et à venir, Marc Lautier revient sur la notion de classe moyenne et son apport en matière de développement socio-économique. Il montre combien les définitions et analyses de la classe moyenne diffèrent et font souvent preuve d’un excès d’optimisme. Retenant pour sa part le niveau de revenu et la capacité de consommation qu’il confère aux individus (autrement dit, une population sortie de la pauvreté), Marc Lautier montre que les classes moyennes, à l’exception sans doute de l’Afrique du Sud, devraient rester très marginales en Afrique subsaharienne, y compris à long terme. Elles ne représenteraient guère plus de 4 % de la population d’ici 2030, ne permettant pas de tirer la croissance de la demande et d’enclencher une expansion économique solide et durable. À un horizon plus lointain, la situation est moins figée et dépendra très largement de la dynamique démographique régionale. S.D.
Quel avenir pour les pays du Partenariat oriental ?
Authors: Drevet Jean-François
Published: May 2023

L’invasion de l’Ukraine par la Russie a conduit, entre autres conséquences, à accélérer l’agenda d’examen de la candidature de Kiev à l’entrée dans l’Union européenne (UE). Si les critères requis pour une adhésion sont encore loin d’être remplis 1 , cette accélération a ravivé les discussions relatives aux candidatures engagées ou à l’approche d’autres pays de la périphérie orientale de l’Union (Balkans, Caucase…). Cette chronique propose de faire le point sur les relations entre l’UE et les pays du Partenariat oriental (Ukraine, Moldavie, Géorgie, Arménie, Azerbaïdjan, Biélorussie). Après un rappel historique (concernant les amorces d’intégration régionale avec la Russie et les candidatures à l’UE des pays des Balkans), Jean-François Drevet présente les scénarios d’évolution possible pour ces pays, au-delà de la politique européenne de voisinage qui régit actuellement leurs relations avec l’UE. Qui est ou pourrait être candidat à l’Union ? Dans quelles conditions ? Il précise ainsi la situation de chacun de ces six pays vis-à-vis de Bruxelles et Moscou, et examine la compatibilité de cette situation avec une entrée dans l’UE.

Les stratégies de social-communication des entreprises touristiques opérant par Yield Management : Quel impact sur l’intention d’usage des messages réseau-publicitaires par l’internaute marocain ? Application du modèle TAM
Authors: Hathout Chaimae , Hamadi Chakib , Hathout Sara
Published: May 2023

Ces dernières années imprégnées d’une large démocratisation de la publicité sur les réseaux sociaux, nous cherchons à modéliser la relation entre les stratégies de communication électronique menées sur ces plateformes par une entreprise pratiquant le Yield management, et l’intention comportementale du cybernaute marocain envers cette forme de publicité sociale. Dans ce cadre, un modèle primaire a été élaboré au fur et à mesure que nous avancions dans notre littérature. Nous avons ensuite cherché à analyser et contextualiser les différents éléments dudit modèle à travers une étude qualitative. Cette version modifiée a elle-même fait l’objet d’une investigation quantitative afin de confirmer ou infirmer nos hypothèses et d’arrêter notre model conceptuel final. Il en ressort une représentation à deux éléments exogènes « qualité des publications » et « qualité de réponse aux internautes », modérés respectivement par « usage des NAV » et « délai de réponse », et qui jouent le rôle d’antécédents à l’intention d’usage du message réseau-publicitaire. Nous estimons avoir pu apporter des éléments de réponse susceptibles d’accompagner les managers dans la production et la diffusion d’un contenu efficace sur les réseaux sociaux. L’idée est de proposer des outils susceptibles de les assister dans le pilotage de l’efficacité de la réseau-communication ainsi que la gestion des composantes de l’intention d’usage des messages réseau-publicitaires chez l’internaute social.
Management inclusif et performance durable de l’entreprise : une revue systématique de la littérature
Authors: Boubakary Ben , Peretti Jean-Marie
Published: May 2023

Le management inclusif constitue un domaine d’étude important dans les entreprises en quête des modèles d’affaire tenant compte de la diversité et de la mixité. Cependant, les recherches sur le management inclusif restent relativement faibles par rapport au développement des connaissances en management stratégique en général. Dès lors, l’objectif de cet article est de proposer un cadre théorique et conceptuel favorable à un modèle économique plus propice au respect de la diversité et de la mixité humaine dans l’entreprise afin d’assurer sa performance durable. Cet article présente une revue systématique de la littérature pour synthétiser la recherche dans ce domaine. Un processus rigoureux a abouti à un échantillon final de 77 documents publiés dans des revues scientifiques entre 1990 et 2020. La synthèse de ces études théoriques et empiriques a révélé que le management inclusif constitue un véritable levier de performance durable de l’entreprise. Par ailleurs, la littérature utilise un éventail étroit de perspectives théoriques et conceptuelles dans l’examen de ces deux notions. Il est donc important que les dirigeants d’entreprises puissent mieux intégrer le management inclusif dans leur stratégie d’affaires afin qu’il contribue véritablement à l’amélioration de la performance durable de l’entreprise. Au regard de la rareté des travaux sur la revue systématique de la littérature en management inclusif, cet article pose les jalons pour une meilleure compréhension des défis à relever par les théoriciens et praticiens pour contribuer, non seulement au développement de ce champ de recherche en termes de théorie, de contenu et de méthodologie, mais aussi pour rendre le management inclusif perpétuellement une source de performance pour l’entreprise.
Et si le Sud régénérait le Nord ? Place à la frugalité
Authors: Frimousse Soufyane
Published: May 2023

Que faire quand les crises se multiplient ? Comment continuer d’innover? Comment agir quand les budgets se réduisent ? Comment continuer à mobiliser les équipes quand l’insécurité domine et qu’il y a perte de repères ? Ce contexte de complexités et d’incertitudes constitue une opportunité de réinventer le management en s’appuyant sur la frugalité qui n’est pas qu’une affaire de coûts et d’innovation. L’article présente donc les principes du concept de frugalité en plongeant dans sa genèse indienne et africaine. Puis, l’intérêt d’une telle démarche pour le continent et les organisations européennes est abordé. Nous démontrons que la frugalité est désormais une compétence recherchée et une réponse à la complexité et l’incertitude du monde et des organisations. D’un point de vue conceptuel, nous verrons que la frugalité s’accommode bien de la théorie de l’effectuation et de la théorie des ressources. En nous appuyant sur les principes de la thermodynamique, nous verrons également que la frugalité est le seul choix pour réussir et relever les défis environnementaux.

Improved Gust Tolerance of a Cyclocopter UAV Using Onboard Flow Sensing
Authors: Shrestha Elena , Yeo Derrick , Hrishikeshavan Vikram , Chopra Inderjit
Published: May 2023

This paper describes the gust rejection study of a twin-cyclocopter micro air vehicle with two cyclorotors and an antitorque nose rotor. A gust rejection controller relying on velocity feedback and onboard flow sensing was implemented in a closed-loop feedback system. Tethered experiments
were conducted with the vehicle mounted on a 6-DOF stand in front of a synthetic gust generation device capable of providing up to 4 m/s step gust input. Planar gusts along the longitudinal and lateral axis of the cyclocopter and crosswinds were systematically studied. Both pitch control (varying
nose rotor rpm) and thrust vectoring control strategies were evaluated to counteract perturbation along the longitudinal axis, while the cyclocopter used differential rotational speed of the cyclorotors for lateral gusts. Results showed that thrust vectoring was more effective than pitch control
in reducing displacement from gust. Pitch control using the position feedback controller resulted in a maximum gust tolerance of 2.8 m/s with a duration of 3 s. while thrust vector control using the combined flow feedback and position feedback controller was able to withstand 4 m/s step gust
input with 1 s duration with only 0.01 m displacement. In addition, flow feedback was more effective than position feedback in minimizing position error. The cyclocopter was also able to mitigate step gusts of 2.8 m/s in magnitude and 3 s duration with crosswind components at 30 deg from the
longitudinal axis. The difference in performance can be attributed to the cyclocopter's unique thrust vectoring capability.

Authors: Halimi Eltjon , Paparisto Anila , Alameti Era
Published: May 2023

This study provides taxonomic and ecological data on Hemiptera (Insecta) order prevalence in Berati region habitats in Southern Albania. Diverse natural environments, fields, and hilly and mountainous habitats characterize this region. The expeditions for the biological material collection were organized during 2018-2020 in six stations from May to September. Our study refers to 38 species, representing 28 genera and 10 families of the order Hemiptera. Taxonomical results on the family distribution indicate that the highest belonged to Pentatomidae, with 12 species or 31.5%, followed by Miridae, with 9 species and 23.6%. Regarding species diversity, the Lybesha station had the highest diversity, with 16 species or 42.1%, while the Lapardha station had the lowest diversity, with six species or 15.7%. Estimating species similarity by the Jaccard coefficient indicates the Lybesha and Peshtani stations, with four common species and a species similarity coefficient of 16.6%, reflecting the ecological factors’ similarity between these stations.
A multicomponent nutraceutical (Perilla frutescens, quercetin, and vitamin D3) as add-on therapy in patients with grass pollen-induced mild persistent asthma and rhinitis
Authors: Marogna Maurizio , Ciprandi Giorgio
Published: May 2023

Background Allergic asthma is an inflammatory disease characterized by a type 2 immune response. Pollens are a common cause of seasonal asthma. Allergic rhinitis (AR) frequently associates with asthma. The treatment usually aims at controlling inflammation and relieving symptoms. Inhaled corticosteroids are the most effective controller and short-acting b2-agonists (SABA) as a reliever for asthma. Oral antihistamines and nasal corticosteroids (NC) are the mainstays for AR. A multicomponent nutraceutical containing perilla, quercetin, and vitamin D3 significantly prevented AR exacerbations in children. Thus, the current study explored the add-on use in adult patients with mild persistent asthma and AR due to grass pollen allergy.

Methods The treatment lasted three months. Asthma and AR symptoms, asthma control test, spirometry, nasal eosinophils, and use of rescue medications (SABA and NC) were evaluated in the previous grass season and throughout the treatment. All patients were treated with ciclesonide (320 mcg/day) and cetirizine (10 mg/day). Patients were randomly stratified into Group A, taking the nutraceutical, and Group B using the predetermined therapy.

Results 90 patients (13-59 years old) were enrolled, and 84 completed the trial. Group A significantly improved all outcomes (p<0.001). Group B did not achieve an improvement in AR symptoms, nasal eosinophils, and nasal steroid use. The intergroup analysis showed that Group A patients experienced less severe bronchial symptoms (- 32 %), AR symptoms (- 39 %), better asthma control (+ 38 %), higher FEV1 (+ 10 %), lower SABA (- 30 %) and NC use (- 41 %), and nasal eosinophils count (- 35 %) than Group B (p<0.0001 for all).

No clinically relevant adverse events occurred.

Conclusion A multicomponent nutraceutical containing perilla, quercetin, and vitamin D3, as an add-on treatment to inhaled ciclesonide and cetirizine, provided a clinically relevant benefit in patients with mild persistent asthma and AR due to grass pollen uncontrolled by standard therapy.
Experience of patients and their caregivers with telepsychiatry consultations: An exploratory study
Authors: Grover Sandeep , Naskar Chandrima , Mehra Aseem , Sahoo Swapnajeet
Published: May 2023

Background:

While telepsychiatry became a prominent and widely used service in the COVID-19 pandemic-related lockdown, data regarding the patient’s experience of telepsychiatry consultations is lacking.

Materials and Methods:

In this study, we attempted to understand the experience and level of satisfaction of 129 patients receiving psychiatry consultations over video consultations from April 2021 to December 2021. We also tried to understand the factors that might be associated with the satisfaction of the patients.

Results:

About three-fourths (77.5%) of the respondents were very satisfied with the quality of care provided and the overall experience of the consultation. The majority (92.2%) of the respondents reported that they would “definitely” recommend the telepsychiatry service to a friend or relative in need of a psychiatric consultation. The majority of the patients expressed high levels of satisfaction with the amount of time spent, the amount of freedom in expressing themselves, the amount of freedom in choosing the treatment option, the prescription provided, and the number of medications prescribed. The clarity of voice and the quality of connectivity throughout the consultation were found to be associated with the level of satisfaction.

Conclusions:

The present study suggests that overall satisfaction with teleconsultations was high among patients and/or caregivers for telepsychiatry consultations.
Prevalence of sexual dysfunction in HTLV-1 patients without spastic paraparesis and the association with psychiatric symptoms
Authors: Kamrani Maedeh , Rad Narges Niazi , Zemorshidi Fariba , Khadem-Rezaiyan Majid
Published: May 2023

Introduction:

The findings of previous studies are inconclusive in terms of psychological abnormalities and sexual function in asymptomatic human lymphotropic virus type 1 (HTLV-1) carriers.

Aim:

This study aimed to evaluate the prevalence of sexual dysfunction and its relationship with psychological abnormalities in asymptomatic HTLV-1 carriers.

Materials and Methods:

This cross-sectional study was conducted on asymptomatic HTLV-1 patients who were referred to the Neurology Clinic of a tertiary hospital in Mashhad, Iran. Patients with spastic paraparesis, leukemia, and uveitis, and those with an expanded disability status scale (EDSS) score higher than 2 were excluded. Sexual function in male and female subjects was evaluated using the brief male sexual function inventory (BMSFI) and female sexual dysfunction index (FSFI) questionnaires, respectively. The severity of psychological symptoms was evaluated in all patients using the symptom checklist-90-revised (SCL-90-R) questionnaire.

Results:

A total of 117 patients (61 males and 56 females) with a mean age of 35.3 ± 6.3 years were evaluated. Overall, 50.9% of males had a high and 39.3% of females had a good sexual function. Both male and female patients with poor sexual function were older and had more children compared to those with good sexual function (P < 0.05). There was no significant difference in the distribution pattern of SCL-90 domains between patients with high and low to moderate sexual function among male patients (P > 0.05). Depression, hostility, interpersonal sensitivity, paranoid ideation, and psychological abnormality were significantly more prevalent in female patients with poor sexual function compared to those with good sexual function (P < 0.05).

Conclusion:

The prevalence of psychological abnormalities was high in female with sexual dysfunction and these disorders might have a negative effect on various dimensions of sexual function.
Impact of economic shocks on mental health during COVID-19: A longitudinal study of adult residents of Indian metropolitan cities
Authors: Husain Zakir , Dutta Mousumi , Ghosh Saswata , Datta Soumitra S.
Published: May 2023

Background:

The causal impact of income shocks on mental well-being in developing countries is an under-researched area. The COVID-19 pandemic, along with the economic recession caused by the lockdowns to reduce transmission, provides a natural experimental setting to examine the causal impact of a decline in monthly per capita expenditure (MPCE) on mental health of the general population in India during the pandemic.

Aim:

To evaluate the impact of income shocks on mental health of adults in metro cities during the COVID-19 pandemic.

Materials and Methods:

The data were collected using the abridged version of the Depression Anxiety Stress Schedule administered through a telephonic survey on adult residents of six metropolitan cities in September–August 2020 and July–August 2021.

Results:

In the present study, 994 adults participated from six metropolitan cities. Average treatment effects were estimated using Propensity Score Matching. The mean normalized scores are significantly higher for respondents whose MPCE had fallen (treated) vis-à-vis respondents whose MPCE had remained same or increased (control): anxiety (0.21 for treated vs –0.19 for control), stress (0.16 vs –0.14), and depression (0.04 vs –0.19). Propensity score matching reveals that the normalized scores for anxiety, stress, and depression were 33 (95% confidence intervals, CI: 20.0–46.7), 25 (95% CI: 12.9–36.9), and 36 (95% CI: 18.6–53.1) higher among the treated group vis-a-vis control group. The ATET was 34 (95% CI: 18.9–48.9), 26 (95% CI: 10.1–42.9), and 32 (955 CI: 12.3–50.7) for these three outcomes, respectively. The post-estimation tests indicated that the results are valid.

Conclusions:

The study advocates that policies to ensure income security should be made an integral part of the response packages to tackle pandemics like COVID-19.

Cotton (Gossypium hirsutum) is a cash crop commonly grown in the savanna zone of West Africa. The objective of this study was to determine the optimum sowing dates for different cotton varieties in Ghana. The study was conducted at the Savanna Agricultural Research Institute (SARI), Tamale, Ghana during 2016-2018 wet seasons. Treatments consisted of sowing dates at four levels, namely mid to late June (PD1), early to mid- July (PD2, mid to late July (PD3) and early August (PD4); and cotton varieties at three levels, i.e. FK37, SARCOT1 and SARCOT5. Treatments were laid out in a split arrangement, with cotton variety as the as the main plot and planting date as the sub plot factor. Results showed that earlier sown cotton maximised seed cotton yield, number of bolls and opened bolls, seed weight, boll weight, plant height, as well as ginning out-turn. Cotton sown early at PD1 produced the highest average (1570 kg ha-1) seed cotton yield, with 10 number of bolls and 9 opened bolls plant-1. SARCOT5 cotton variety produced the highest (1223 kg ha-1) seed cotton yield; while FK37 gave the lowest (861 kg ha-1) yield. The interaction between PD1 and SARCOT5 produced the highest (1777 kg ha-1) seed cotton yield and could be recommended for viable cotton production in the Guinea savanna agroecology of Ghana.

This study examined the effect of women participation in artisanal fishing on their Socio- economic well-being in coastal communities in Cross River State, Nigeria. The study focused specifically on the socio-economic characteristics of women artisanal fish farmers, areas of women participation in artisanal fishing, and effect of women participation in artisanal fishing on their socio-economic well-being. The population of the study comprised all rural women in the coastal communities, who are involved in artisanal fishing activities. The sample was drawn from the population of the study using simple random sampling techniques. A total of 200 respondents were used for the study. Data were collected using a semi-structured interview schedule, and analyzed using the mean, ranking, percentages and ordered probit regression model. Results of analysis indicated that 66% of the women were between the ages of 20-40 years, 39.5% of them attended secondary school, 60% of the women had 3-6 children and about 58% of them were married. Women were also involved in a wide range of areas of artisanal fishing, including fish catch, unloading of fish from canoes, fish processing and carrying and repair of fish gear etc. The study found that women participation in artisanal fishing enabled them to have more money (ranked = 1st), do not lack money again (ranked=2nd ),allowed them to build their own houses (ranked = 3rd) and enhanced their capacities to contribute donations to charities (ranked = 4th) among others. The result of probit analysis revealed that women participation in artisanal fishing was determined by their level of education, credit facilities, age, cultural/religious variables, and family factors etc. The study recommended that government should provide credit facilities in form of grants to rural women involved in artisanal fishing and provide basic training in terms of safety protocol, preservation and processing of fish.

Hate speech is a prevalent issue on social media platforms that has recently been a cause for concern due to its detrimental effects on individuals and society. The development of effective hate speech detection procedures and algorithms is crucial to address this issue. However, the existing natural language processing (NLP) algorithms and machine learning models face several challenges in accurately identifying and categorizing hate speech. These challenges include the ambiguity and variability of language use, the lack of standardized definitions and guidelines for hate speech, and the rapid evolution of new and creative forms of hate speech. In this paper, we propose a technique that leverages classic machine learning and deep learning methods to locate and categorize hate speech in social media. Our approach involves the use of Support Vector Machines (SVM) and Long ShortTerm Memory (LSTM) networks for classification. We evaluate the performance of our model on a hate speech dataset and compare it with a deep learning-based model. Our results show that the SVM model outperforms the deep learning-based model in accuracy and efficiency. Our approach offers a promising solution to the challenges posed by hate speech detection on social media and contributes towards building a safer and more welcoming online community.

The pipeline is one of the main modes oftransportation for the oil and gas industry that could be laid offshore and onshore. Pipeline transportation requires close monitoring as a failure in pipelines causes disruption of supply, loss of precious commodities and not to mention irreversible environmental damage will be an essential topic. The major issue in AODV and DSDV is when the network gets more extensive, which causes high packet traffic resulting in high packet loss, energy consumption and passive nodes. This research aims to establish a routing algorithm with better performance focusing on throughput, fairness index, delivery ratio and passive nodes and energy consumption. The study is confined to wireless sensor network simulation on Network Simulator Tool. A technique of quad-interleaving Ad-hoc On- demand Distance Vector (QAODV) routing algorithm has been developed where predefined Alpha, Beta, Charlie and Delta nodes will communicate with the nodes which belong to their family. The results of the developed routing protocol have been compared with standard AODV, DSDV and OLSR routing protocols. The developed routing algorithm has produced a massive improvement in the delivery ratio (25% more), throughput (44% more), passive nodes (71 less), fairness index (0.06 more) and energy consumption (0.22J less).

—Efficiency in photovoltaic (PV) energy production is significantly influenced by various electrical, environmental, and manufacturing-related factors. These variables often lead to a range of PV generator faults, compromising the system's performance and the overall grid's safety. The current fault detection methods can be complex and resource-intensive. In this paper, we propose a novel and efficient grid-connected PV system fault detection mechanism using the k-means clustering algorithm. Our approach categorizes the possible faults based on clustering the output PV and grid powers under healthy and faulty conditions. A comparison between centroid locations of both conditions leads to fault categorization. The findings demonstrate the efficacy of the proposed technique for addressing localized faults in grid-tied PV systems without the need for complicated calculations. The technique is both cost-effective and accurate, with a straightforward application that can be easily adopted by all stakeholders. This method enables users to safeguard their PV system's health and ensure the more comprehensive grid's safety.

ICT security has proven to be important in any organization in dealing with digital data. In implementing data protection, there are several challenges that an organization may encounter such as employee’s lack of awareness and education, cybersecurity threats, data breaches, lack of technical infrastructure, and limited resources. To combat internal security threats and encourage employees' security habits every agency, in the different sectors of the government must practice and promote data protection awareness against cybercrimes. To improve the security posture of every public or private organization in the Philippines. This study looked at a newly suggested security management standard that offers a thorough framework for detecting and evaluating risks to ICT (information and communication technology) systems and applications. The proposed standard strongly emphasizes the necessity of ongoing security control monitoring and assessment, frequent recovery plan testing and evaluation, and compliance with the PDCA Model anchored to the ISO/IEC 27001 standard and the Data Privacy Act of 2012. The study examined the suggested standard's main aspects and potential business advantages, including security, compliance, and stakeholder coordination and communication as well as emphasized the difficulties in implementing the suggested standard, including the requirement for significant resources and knowledge. The proposed standard also provides a common language for communication and collaboration among stakeholders, including I.T. staff, business leaders, and external partners. This can help promote a security culture and ensure everyone in the organization works together towards a common goal.
