Authors: Amaliah Tri , Lukum Amir
Published: September 2022

Permasalahan sampah hingga saat ini masih menjadi problematika masyarakat, tak terkecuali yang dialami masyarakat di Desa Huangobotu Kecamatan Kabila Bone. Dalam mengatasi permasalahan sampah di Desa Huangobotu sejauh ini telah dilakukan pelatihan pengolahan sampah plastik. Sampah plastik yang berasal dari tutup botol minuman kemasan plastik dijadikan vas bunga, asbak rokok dan lainnya yang dapat juga dijadikan souvenir. Namun, karena benda-benda souvenir yang telah dihasilkan dari limbah plastik tidak dipasarkan ke pubik, maka hanya disimpan sebagai pajangan di Kantor Desa. Padahal benda-benda souvenir yang dihasilkan sebenarnya dapat dijadikan komoditas yang menghasilkan pundi-pundi penghasilan masyarakat setempat. Selama ini memang belum pernah dilakukan sosialisasi dan pelatihan terhadap sistem pemasaran digital yang dapat mengatasi kesulitan ekonomi yang tengah dihadapi oleh masyarakat Desa Huangabotu khususnya di masa pandemik Covid 19 saat ini. Pelatihan ini dimaksudkan untuk membantu istri-istri nelayan yang terdapat di Desa Huangobotu sehingga memiliki kemampuan dan kesadaran dalam penyelenggaraan teknik pemasaran digital sebagai sarana untuk menambah penghasilan terhadap hasil olahan sampah yang selama ini telah dihasilkan. Pelaksanaan pelatihan dilakukan dengan menggunakan metode praktik dalam hal teknis pemasaran digital, melalui pembuatan website pada media sosial yaitu facebook (marketplace) dan instagram untuk menangkap peluang-peluang bisnis secara luas. Program pengabdian ini sangat bermanfaat dalam memberikan kontribusi terhadap peningkatan kompetensi kaum perempuan khususnya istri-istri nelayan di Desa Huangabotu untuk meningkatkan pendapatan. Dengan pengetahuan dan keterampilan yang dimiliki, masyarakat di Desa Huangobotu dapat menghasilkan karya dari sampah plastik dan dipasarkan ke masyarakat yang membutuhkan.

Published: September 2022

The paper presents new possibilities of using a mixed method for calculating bendable plates with complex boundary conditions. When composing resolving equations, it is sufficient to have an expression to determine the deflections of a plate with a normal pinched at the origin. Such solutions are given in the authors’ previously published works for plates of various shapes. On the basis of these solutions, the canonical equations of the mixed method are compiled, where the unknown forces of the method are the forces in the support links, the displacement method is linear and angular displacement of the pinching introduced at the origin. After determining the unknown forces of the method, according to the generally accepted formulas of the mixed method, the deflections of the plate are determined, according to which, in turn, internal forces are determined. Two examples of calculating plates in Cartesian and polar coordinates are given. Numerical implementation of the proposed methodology and algorithm for elastic calculation of bendable plates with complex boundary conditions is carried out using the Wolfram Mathematica 11.3 computer program.

When solving frame stability problems, replacing a distributed load acting on a frame element with an equivalent load in the form of concentrated forces that are applied in the frame nodes is often resorted to. This causes the bending equilibrium of the beam to become a non-bending tension-compression equilibrium. The buckling load for such frames can be either greater or less than the actual load.

Published: September 2022

The article considers the calculation of the effective length of an under-ream bored pile and a pile without broadening. The pile is located under axial compression conditions in a homogeneous ground of the base. Reducing the cost of piles is an important problem, since the manufacture of piles with broadening is characterized by increased cost. This can be achieved by identifying the value of the effective pile length. The length of the pile is considered effective if a stress in the ground is reached under its widened part equal to the calculated value R of the resistance of the ground of the base. The values of soil resistance are given in SP 24.13330.2011 (2021) for different soils at different depths of immersion of the Hc pile. In the paper, the tabular values of H and R are presented as a dependence of R on Hc (functions). The type of these functions is determined by the least squares method. In contrast to the instructions for the calculations of piles according to JV 24.13330.2011 (2021), a different design scheme for the operation of the pile in the ground of the base is proposed without bringing it to a “breakdown”. As a result, a calculation equation is presented to determine the effective length of the under-ream bored pile. Similar calculations are applicable for piles without broadening.

For a comprehensive assessment of the management decisions quality, it is necessary to take into account heterogeneous information presented both in numerical form and in natural language expressions. The effective occurs the use of data mining including neural network clustering and fuzzy set theory. The article presents our approach to the use of these methods for evaluating risks and the management decisions quality in Russian higher education on the example of the implementation of the most ambitious Project 5-100 for it. On the example, the expediency of the neural network clustering to assess the possibility of achieving the goals of any such large-scale project has been proved. Clustering the information database used for the analysis, makes it possible to carry out an objective selection of candidate universities-candidates for the right to receive state subsidies, as well as to adjust the composition of the Project participants. Another methods of intellectual analysis – the construction of a complex of fuzzy inference systems, – confirmed the possibility of a quantitative fi evaluating of the project based on the expert verbal estimates of the project. At the same time, the neural network clustering initially illustrated the unattainability of the Project 5-100 goals. The use of a complex of fuzzy inference systems confirmed this statement by the very low quantitative final assessment of the project on the basis of verbal expert opinions.

Published: September 2022

Communication network simulators are software designed to model, explore, test and debug network technologies, including wireless decentralized self-organizing networks or ad-hoc networks. They greatly simplify the research, development and optimization of routing protocols in these networks. However, the well-known simulators have a number of disadvantages, including the difficulty of adding custom extensions to ad-hoc network routing protocols, the lack of the necessary network stack, the lack of routing algorithm visualization modes, low performance, and difficulty in debugging communication protocols. The purpose of this work is to create a simulation model of a wireless network that would allow us to explore, debug and evaluate the developed algorithms and routing protocols for ad-hoc networks. At the same time, the requirements for interface ergonomics and the ability to visualize the operation of algorithms, ensure the collection of statistics, and create various scenarios for the operation of the network come to the fore. The article proposes the structure of the simulation model, which includes the modules of the network subscriber, application software, network layer of the OSI data transmission model, radio module, radio transmission environment, statistics collection, visualization and scenario management. To solve the tasks set, the approach of discrete-event modeling was used. To create a simulator of wireless decentralized networks and routing algorithms, a set of classes was developed that implement the modules of the simulation model. Based on the proposed structure, module classes and discrete event simulation algorithm, a software implementation of the simulation model was created using the C++ programming language and the Qt framework. The developed simulation model was used in the course of an experimental study of the effectiveness of the network routing algorithm. The proposed software will simplify the development and debugging of algorithms and routing protocols for ad-hoc networks.

Published: September 2022

The article provides a rationale for the relevance of developing a recommender system in the field of e-learning. The main approaches to building a recommender system are analyzed: collaborative, content and hybrid filtering. The main objects of the recommender system for choosing online courses are presented: the student, training modules (online courses), elements of knowledge that the user can receive at the end of the training. In algorithmic support, methods for creating recommender systems, such as machine learning, neural networks, genetic algorithms, are considered. Problems in the methods of building recommender systems have been identified: sparseness; cold start; scalability; searching for elements that are most likely to be preferred by the user from a common set of elements. The main problem of recommender systems is to obtain an accurate and high-quality recommendation for the selection of educational objects in accordance with user preferences. It is concluded that it is necessary to build an architecture of a recommender system, including a model of an individual learning trajectory. Filtration of educational objects occurs with the help of a genetic algorithm. The expediency of using a microservice approach to create a web application is determined. The functional tasks of the developed system are highlighted, such as data collection, analysis of user requests, the formation of educational objects using an individual learning trajectory and the issuance of recommendations for choosing online courses. An algorithm for the functioning of the recommender system, a scheme for the operation of the recommender system, as well as information support for the operation of this system have been developed. A general approach to the development of a universal recommender system that can be integrated into the client's service is proposed. The purpose of developing a recommender system for choosing online courses is to provide students with the most appropriate learning objects (sequence of objects) to study in accordance with the characteristics of the student and fragments of knowledge (competencies).

Published: September 2022

The present research investigated the characteristics of convective boundary layer flow and heat transfer of the blood carrying ferroparticle modelled known as the non-Newtonian Williamson hybrid ferrofluid. The fluid flow and the heat transfer of a stagnation point over a stretching surface are considered. The similarity transformation approach is used to reduce the partial differential equation system to an ordinary differential equation. The transformed equations are then solved numerically by Runge-Kutta-Felberg (RKF45) method in Maple software. The flow characteristic and the heat transfer of the non-Newtonian Williamson hybrid nanofluid are tested from various pertinent fluid parameters. The temperature distribution, velocity profiles, as well as variation of the Nusselt number and the skin friction coefficient are analysed and discussed. The study reveals that the non-Newtonian Williamson Hybrid ferrofluid potentially provided better performance in heat transfer capability compared to ferrofluid with the same volume of nanoparticle volume fraction.
A Study of the Background to the Book of Amos
Authors: Boaheng Isaac
Published: September 2022

The book of Amos is among the most studied books in the Bible. The high scholarly interest in Amos is due to the prophet’s emphasis on true religion. Amos’ message cannot be understood without a proper understanding of the context in which it was delivered. Amos ministered in eighth-century Israel when the nation had prospered economically and politically. The nation’s prosperity had yielded a high level of religiosity evident in the payment of tithes, offerings, religious gatherings and singing of hymns. Unfortunately, the religiosity of the people had no positive impact on their social lives. This situation prompted Amos’ prophecy of an impending divine judgment which was to decimate the nation and finally send the people into exile. The purpose of this paper is to explore the contextual issues within which Amos’ message emerged and then compare Amos’ situation with the contemporary Ghanaian socio-religious and political contexts. The paper used literary research methodology as well as textual and historical analyses. The findings from the study serve as a hermeneutical framework for interpreting and applying Amos’ message. Lessons are also drawn for contemporary leaders. The paper contributes to Old Testament scholarship, particularly scholarship on the minor prophets.

Review of Kevin DeYoung’s What does the Bible really teach about homosexuality?
Authors: Phelan James E.
Published: September 2022

In his book, “What does the Bible really teach about homosexuality?” theologian Kevin DeYoung compares his own conservative biblical hermeneutics to those of contemporary revisionists as it relates to homosexuality throughout the Bible in the following: Sodom and Gomorrah, Leviticus and the Mosaic Law – covenant, Romans 1:18-27, 1 Corinthians 6 and 1 Timothy 1. In understanding these passages in the Bible, DeYoung concludes that homosexuality is immoral behavior, and that marriage should only be between one man and one woman. This contrasts with revisionists who argue that the homosexuality mentioned in the Bible was not the same as current same-sex relationships in committed contexts. The book is composed of two main parts. Although the book is written by a theologian, it is easy to read even in part 1 where DeYoung discusses his own biblical hermeneutics in simplest terms. Part 2 is objection handling which he does with graceful rebuttal. His conclusion is not about slamming those who might disagree with him (conservative vs. progressive), but rather exchanging potential discourse with grace while considering exegetical, historical, and theological conclusions. DeYoung includes an annotated bibliography of resources that are representative of his view, written in introductory, intermediate, and advanced levels.

Supernova Precursor Emission and the Origin of Pre-explosion Stellar Mass Loss
Authors: Matsumoto Tatsuya , Metzger Brian D.
Published: September 2022

A growing number of core-collapse supernovae (SNe) that show evidence for interaction with dense circumstellar medium (CSM) are accompanied by “precursor” optical emission rising weeks to months prior to the explosion. The precursor luminosities greatly exceed the Eddington limit of the progenitor star, implying that they are accompanied by substantial mass loss. Here, we present a semi-analytic model for SN precursor light curves, which we apply to constrain the properties and mechanisms of the pre-explosion mass loss. We explore two limiting mass-loss scenarios: (1) an “eruption” arising from shock breakout following impulsive energy deposition below the stellar surface; and (2) a steady “wind,” due to sustained heating of the progenitor envelope. The eruption model, which resembles a scaled-down version of Type IIP SNe, can explain the luminosities and timescales of well-sampled precursors, for ejecta masses ∼ 0.1–1 M
⊙ and velocities ∼ 100–1000 km s−1. By contrast, the steady wind scenario cannot explain the highest precursor luminosities ≳ 1041 erg s−1, under the constraint that the total ejecta mass does not exceed the entire progenitor mass (though the less luminous SN 2020tlf precursor can be explained by a mass-loss rate ∼ 1 M
⊙ yr−1). However, shock interaction between the wind and pre-existing (earlier ejected) CSM may boost its radiative efficiency and mitigate this constraint. In both the eruption and wind scenarios, the precursor ejecta forms compact (≲1015 cm) optically thick CSM at the time of core collapse; though only directly observable via rapid post-explosion spectroscopy (≲ a few days before being overtaken by the SN ejecta), this material can boost the SN luminosity via shock interaction.

We present Hubble Space Telescope (HST) observations of the Type IIb supernova (SN) SN 2016gkg at 652, 1698, and 1795 days from explosion with the Advanced Camera for Surveys (ACS) and Wide Field Camera 3 (WFC3). Comparing to pre-explosion imaging from 2001 obtained with the Wide Field Planetary Camera 2, we demonstrate that SN 2016gkg is now fainter than its candidate counterpart in the latest WFC3 imaging, implying that the counterpart has disappeared and confirming that it was the SN progenitor star. We show the latest light curve and Keck spectroscopy of SN 2016gkg, which imply that SN 2016gkg is declining more slowly than the expected rate for 56Co decay during its nebular phase. We find that this emission is too luminous to be powered by other radioisotopes and infer that SN 2016gkg is entering a new phase in its evolution where it is powered primarily by interaction with circumstellar matter. Finally, we reanalyze the progenitor star spectral energy distribution and late-time limits in the context of binary evolution models. Including emission from a potential companion star, we find that all such predicted companion stars would be fainter than our limiting magnitudes.

Published: September 2022

BACKGROUND: The coronavirus disease 2019 (COVID-19) is an infectious disease characterized by severe acute respiratory syndrome caused by the coronavirus 2. The implementation of lockdown and social distancing is the efforts made by the government to prevent the spread of this virus. The COVID-19 pandemic has affected the incidence rate of ocular trauma in several means.

AIM: This study aimed to evaluate the factors that can cause ocular trauma, from the patient’s characteristics, clinical presentation, etiology, and mechanism of ocular trauma of patients who came to the emergency unit of Sanglah Central General Hospital (RSUP) during the COVID-19 pandemic.

METHODS: This study is an observational analytic study with simple random sampling method to evaluate the characteristics of patients with ocular trauma from March 2020 to March 2021. The secondary data were obtained from the medical records including age, gender, address, examination data (visual acuity, duration between trauma and time of seeking medical care, diagnosis, trauma etiology, trauma mechanism, and surgery performed on the patient).

RESULTS: In this study the most common was the presence of corpus alienum/foreign body in the cornea, chemical trauma, corneal erosion, canaliculi rupture, and keratitis which are usually caused by photoelectric injury. During the COVID-19 pandemic, new regulations were implemented including patient screening, COVID-19 test before undergoing surgery, patient treatment, and also the use of personal protective equipment for the examiners. Moreover, there were behavioral changes of the people caused by the enforcement of lockdown system and also people’s fear of going to the hospital, especially to a COVID-19 referral hospital such as Sanglah General Hospital; therefore, some patients delayed seeking medical treatment and refused to have surgery at Sanglah General Hospital.

CONCLUSION: Our study concluded that the trend of ocular trauma in the COVID-19 era tends to occur in the male population and involves trauma to the cornea, with the most common etiology is caused by the presence of foreign bodies such as gram, wood, or metal. Our finding also showed that despite the implementation of social distancing policies in the COVID-19 pandemic situation, ocular trauma can still be found related to the implementation of the lockdown that has been relaxed during this research.

Authors: Asreah Rabah , Atta Sama , SarKo Saman
Published: September 2022

BACKGROUND: Enteric fever caused by Salmonella Typhi is an endemic disease in Iraq. Variations in presentations make it a diagnostic challenge. If untreated or treated inappropriately then it is a serious disease with potentially life-threatening complications. The recent emergence of drug resistant strains of S. Typhi is a rising public health problem and a clinical concern to the physician.

AIM: The objectives of the study were to assess and describe the patterns of antimicrobial resistance, clinical characteristics, epidemiological distribution, and complications of typhoid fever.

PATIENTS AND METHODS: Fifty cases of typhoid fever (culture proven) were collected during the period from February 2019 to November 2019 in the medical wards of Baghdad Teaching Hospital. Detailed history, physical examination, and laboratory investigations were conducted and statistical analysis of the results was done, prospective observational study was conducted.

RESULTS: During the study period, 50 cases of typhoid fever were documented, mean age of presentation was 30.7 ± 12.8, 60% of the cases were male gender, gastrointestinal complications were the most common (90%) followed by hematological complications (71%). Mortality of typhoid fever in our study was 2%. High percentage of resistance to third generation cephalosporins, ciprofloxacin, and azithromycin was found (96%, 56%, and 56%, respectively) while good sensitivity to trimethoprim and meropenem was found (94% and 76%, respectively). Significant association was also found between the development of typhoid fever complications and the presence of anemia, thrombocytopenia, lymphopenia, and eosinopenia. Significant association was also found between the complications and the infection with strains resistant to cephalosporins, ciprofloxacin, and azithromycin.

CONCLUSIONS: There is a concerning increase in resistance toward cephalosporins, ciprofloxacin, and azithromycin while meropenem and trimethoprim are emerging as effective drugs. There was high incidence of complications found (84%).Lymphopenia, anemia, eosinopenia, and thrombocytopenia are independent risk factors for the development of complications of typhoid fever.
Diversifying the GBIF Data Model
Authors: Robertson Tim , Wieczorek John , Raymond Mélianie
Published: September 2022

The Global Biodiversity Information Facility (GBIF) has been immensely successful in mobilizing a large number of records documenting species occurrence through a global network of data publishers. Today over 2 billion records are available for search and download through the GBIF.org infrastructure, with over 200 million originating in natural science collections or gleaned from citations of specimens in literature. These data are most commonly made available through the TDWG standards Darwin Core and Access to Biological Collections Data (ABCD) with their various extensions.

The growth of the GBIF network has generated new challenges and a desire for GBIF to accommodate more varied types of data (e.g., ecological, eDNA, biological interactions, material samples with subsamples and associated media, taxonomic treatments), acknowledging that biodiversity data are more complex than ‘just’ the occurrence of species in time and space. GBIF has initiated work to explore the diversification of the data model that underpins the datasets connected to GBIF, and the services provided by its infrastructure. During 2021, several case studies were drafted and analyzed to establish a draft common domain model that could satisfy the key aspects of the studies. The cases cover a range of concerns, including automated monitoring, identification through sequencing techniques, biotic interactions, environmental measurements, and improvements to the handling of data representing preserved material. The draft model has been presented publicly several times and is being tested and matured to accommodate real datasets during 2022.

This presentation will summarise the process followed, provide an overview of the cases that have been explored, and show the resulting model. We will describe the ongoing opportunities for community engagement as this work continues. We will provide insight into some of the lessons we have learned and how this research has the potential to help integrate many efforts relating to the use of the Darwin Core-related standards today.
Representation of Object Provenance for Research on Natural Science Objects: Samples, parts and derivatives in DINA-compliant collection data management
Authors: Bölling Christian , Bilkhu Satpal , Gendreau Christian , Glöckler Falko , Macklin James , Shorthouse David
Published: September 2022

Collection objects in natural science collections span a diverse set of object types of substantially different origin, physical composition, and relevance for different fields and methodologies of research and application. Object provenance is often characterized by elaborate series of interventions from collecting or observing originals in a natural state to generating derived objects that can be physically persistent or are suitable for a given use. This sequence of events gives rise to intermediate objects or object states that can be of a persistent or ephemeral nature in their own right. Detailed metadata on object provenance is vital to enable informed use of collection objects for research and other application areas. Providing the ability to generate, maintain, update and access such accounts is an important requirement for Collection Management Software (CMS).

DINA (Digital Information System for Natural History Data, Glöckler et al. 2020)-compliant collection management software meets this challenge by using process- and state-based representation of object histories and modular application architecture as the main conceptual and architectural principles, respectively (Bölling et al. 2021).

In applying these principles, we showcase how object provenance can be represented in the DINA system in cases where

multiple objects, possibly of varying types, are derived from a single object,

objects consist of parts of different biological individuals,

object histories involve different types of objects such as living biological individuals, samples, and preserved specimens.

multiple objects, possibly of varying types, are derived from a single object,

objects consist of parts of different biological individuals,

object histories involve different types of objects such as living biological individuals, samples, and preserved specimens.

We highlight how the abstractions and categories used in the DINA model can be used to meet a variety of challenging use cases for representing collection object provenance. For instance, while the connections and relationships between living, preserved, and even destructively processed samples can be documented in DINA, these are ordinarily difficult to accommodate in a single information system.
A new massopodan sauropodomorph from Trossingen Formation (Germany) hidden as ‘ Plateosaurus’ for 100 years in the historical Tübingen collection
Authors: Fernández Omar Rafael Regalado , Werneburg Ingmar
Published: September 2022

A literature review showed that there is not a defined consensus on what specimens belong to Plateosaurus in current phylogenetic analyses, and after the assignation of SMNS 13200 as the neotype for Plateosaurus, the specimen composition of Plateosaurus as an operational taxonomic unit (OTU) needs to be addressed in further iterations of phylogenetic analyses. At least one of the specimens used to illustrate plateosaurian anatomy contains several characters identified in more derived sauropodomorphs commonly referred to as massopodans. This partial skeleton, traditionally known as specimen ‘GPIT IV’, was found in the lower dinosaur bone bed of the Obere Mühle, a Trossingen Formation outcrop, during an excavation in 1922 near the city of Tübingen, Germany. The holotype of Plateosaurus trossingensis and several other specimens referred to as this species were found in this level, which was initially interpreted as a synchronic deposit of animals. However, the current understanding of the Trossingen Formation indicates that this bed was probably a constant accumulation of carcasses through miring and transport down a river for hundreds of years. In this work, a framework to compare phylogenetic signals with morphological and histological data is provided to help in the species delineation of Plateosaurus, and support is found to refer the historic specimen ‘GPIT IV’ as a new genus and a new species.
Wallon et l’éphémère, face cachée du développement
Authors: Nadel Jacqueline
Published: September 2022

Wallon a défini l’enfance comme « un chantier dont certains organes assurent l’activité présente tandis que des masses importantes s’édifient, qui n’auront leur raison d’être qu’aux âges ultérieurs ». Si l’on prend au mot la métaphore, le futur et le présent cohabitent. Et pourtant c’est à les séparer que s’est employée la psychologie. Comment Wallon voyait-il les rapports entre la psychologie de l’enfant et la psychologie du développement ? Quelle est la place de l’éphémère dans sa vision du développement ? Quel rôle joue l’équilibre fonctionnel comme modèle d’une adaptation sans cesse renouvelée de l’individu à son milieu ? Quelle est sa définition du milieu ? C’est ce que cet article s’essaie à questionner, comme une moderne rencontre avec le modèle darwinien de l’adaptation individuelle tel qu’élaboré par Wallon.
L’importance des émotions dans la vie sociale des enfants : et si Wallon avait vu juste ?
Authors: Brun Philippe
Published: September 2022

La pensée d’Henri Wallon accorde une place prépondérante aux émotions dans la description du développement de l’humain. Il s’agit là d’une évidence pour le lecteur intéressé par ses travaux. Précisément, cet article se propose d’esquisser trois axes de recherches actuelles qui permettent notamment de rappeler la modernité et l’originalité des propos wallonniens, originalité que les méthodologies contemporaines en psychologie du développement ou en sciences de l’éducation ont pu éprouver et souvent rejoindre. Parmi ces perspectives, nous présenterons brièvement l’heuristique wallonienne concernant l’étude de la régulation émotionnelle chez l’enfant, la question de la loyauté entre enfants et des interactions émotionnelles qu’elle suppose, et enfin, les récentes propositions qui conduisent le monde de l’éducation scolaire à s’interroger sur la pertinence des climats émotionnels entre enfants, entre enseignant et élèves.
Henri Wallon et Lev Vygotsky

Dans l’étude du développement cognitif de l’enfant, la comparaison entre les analyses de Wallon et de Vygotsky a peu porté sur la période des trois premières années. À l’époque où Vygotsky cite Wallon, tous deux, en se fondant principalement sur la méthode d’observation, ont une approche théorique commune : le bébé vu comme un être social ; le développement par stades et crises… En examinant les six volumes des Œuvres choisies de Vygotsky, publiées en langue russe, puis en anglais, nous en avons extrait l’intégralité des références à Wallon concernant le développement de la conscience de soi. Nous montrons qu’Henri Wallon a pu exercer un certain rôle dans la représentation de Lev Vygotsky sur les conquêtes extéroceptives des premiers mois, sur les prémisses de la conscience corporelle et sur l’émergence du langage. Nous comparons également leurs apports respectifs sur le développement émotionnel, l’interaction triadique et la crise des 3 ans.
Ce que l’international fait à l’économie (et réciproquement)
Authors: Gayon Vincent , Lecler Romain
Published: September 2022

Les politiques économiques internationales constituent un objet de recherche prometteur pour la sociologie politique de l’international. Malgré quelques amorces en direction de la sociologie, les courants classiques de l’économie politique internationale puisent en effet davantage leur inspiration dans les sciences économiques. Cette introduction souhaite contribuer à un rapprochement critique entre ces perspectives disciplinaires en s’appuyant sur une série de travaux sociohistoriques qui cherchent à éviter le piège de la réification des États et des organisations, et se méfient de l’illusion héroïque et téléologique dans la conduite de l’action publique internationale. Elle montre tout l’apport d’une sociologie des agents, attentive à rendre compte de leurs pratiques, à éclairer leurs trajectoires et leurs dispositions, à analyser la structure de leurs interactions, de leurs conflits et de leurs stratégies au cœur des bureaucraties économiques internationales.
Les origines non-néolibérales d’un « tournant néolibéral »
Authors: Alayrac Pierre
Published: September 2022

Cet article explore les affinités électives entre économicisation et néolibéralisation qui permettent d’analyser avec une chronologie longue le « tournant néolibéral » des années 1980 à Bruxelles et ses conditions de possibilité. Il montre dans quelles situations, et avec quels effets, une technologie économique construite comme aide à la décision publique comme l’analyse coût-bénéfice s’est généralisée et a pu être utilisée pour encourager l’approfondissement de l’intégration économique puis la reconfiguration du pouvoir sur l’économie européenne entre États, administration communautaire et marchés. L’analyse complète la littérature existante en proposant d’analyser les origines dudit tournant dans les politiques du Marché intérieur.
Souvenirs d’un apparatchik sans avenir
Authors: Gayon Vincent
Published: September 2022

Cet article souhaite éclairer la teneur pratique et conflictuelle du « libéralisme encastré » d’après-guerre et de son délitement. Il prend le parti d’exhumer la trajectoire d’un haut fonctionnaire emblématique de l’Organisation de coopération et de développement économiques (OCDE) : Stephen Marris. Devenu « conseiller économique spécial » du secrétaire général, il est effacé des récits historiques officiels depuis qu’il y a été désigné persona non grata en 1983 en plein tournant reagano-thatchérien. Le pari de recherche consiste à saisir, sur une trentaine d’années, l’économie évolutive des soutiens à ce « charisme de fonction » et, spécifiquement, les réseaux de consolidation transgouvernementaux des pôles monétaires et financiers des États membres.
Numerical and experimental investigation for analyzing the temperature influence on the performance of photovoltaic module
Authors: Mohammad Abdulrahman Th. , Al-Shohani Wisam A. M.
Published: September 2022

The effect of temperature is considered a significant factor in controlling the output voltage of the photovoltaic (PV) module. In this work, a numerical analysis with an experimental demonstration were investigated to analyze the temperature effect on the performance of PV module. In the numerical part, the current-voltage I-V and power-voltage P-V curves of the PV module were simulated under the influence of various module temperature ranged from 25 to 65 ℃ as well as various solar radiation from 200 to 1000 W/m2. In addition, the variation of PV output electrical characteristics with a module temperature were performed to analyze the temperature coefficients of the PV module. Moreover, the experimental demonstration was performed to analyze performance of the PV module under the real weather conditions of Iraq. The numerical results conclude that the maximum power was recorded 165 W at 1000 W/m2 solar irradiance and 25 ℃ PV module temperature. Furthermore, the temperature coefficient was recorded a maximum value with output power about (−0.26) %/℃. Besides, the experimental results show that the maximum power was recorded 131.2 W at solar irradiance about 920 W/m2.

Determining the joint pricing and ordering policy is a challenging task for policy-makers dealing with perishable items. This research deals with the inventory coordination for a decaying commodity under a non-linear price-sensitive demand structure where the policy-maker completes the payment partially in advance, exploiting the multiple installments facility to control supply disruptions. Moreover, an inventory-out situation is incorporated to make the model more representative; shortages are backlogged partially through a variable rate in exponential form, depending on the customer waiting times. Though the formulated inventory coordination creates a highly complex optimization problem, the existence of the joint optimal pricing and ordering policy is explored by developing several theoretical outcomes. Three numerical illustrations are adopted to ensure the effectiveness of the model in providing the joint optimal pricing and ordering policy for the decision manager. Furthermore, to visualize the concavity of the average profit of the policy manager, as well as to demonstrate the adequacy of the optimum condition, MATLAB software was utilized. Finally, sensitivity studies for known key parameters are done using graphic presentation and a few supportive guidelines for the manager are also shown. The inventory manager should motivate the supplier to allow a higher installment frequency to implement the prepayment regulation, thus reducing the capital cost against the prepayment amount.
