Fécondité différentielle au début du XX e siècle selon la classe sociale des femmes. Les cas de la Belgique et de la France
Authors: Bourguignon Mélanie , Brée Sandra , Eggerickx Thierry , Sanderson Jean-Paul
Published: April 2020

Cet article a pour objectif d’analyser la relation entre la fécondité et la classe sociale des femmes dont la vie reproductive se déroule durant les premières décennies du xx e siècle en France et en Belgique. Le niveau d’instruction de ces femmes est considéré ici comme une mesure de l’appartenance sociale et l’analyse repose sur l’exploitation de données rétrospectives extraites des recensements de la population de la Belgique et des enquêtes Famille réalisées en France. Durant cette période de « fin de transition », marquée par des contextes socioéconomiques et politiques de crises, observe-t-on des différences significatives de fécondité entre catégories sociales ? Et les « mécanismes » de la restriction de fécondité (contraception d’arrêt, report de naissance, célibat définitif…) varient-ils selon ces catégories sociales ? Des analyses, il ressort que le déclin de la fécondité est généralisé, quel que soit la classe sociale des femmes, mais qu’il survient selon des ampleurs variables. L’antériorité du mouvement chez un groupe particulier est toutefois difficilement confirmée, la perspective historique des données ne permettant pas d’observer les premiers signes de décrochage de la fécondité. Les comportements de fécondité sont davantage orientés vers une contraception d’arrêt, avec une maîtrise de plus en plus efficace du destin génésique, surtout au sommet de la pyramide sociale.
Forced Separation and Intercountry Adoption: The Invisible Narrative of the War in Lebanon
Authors: Ismail-Allouche Zeina
Published: April 2020

L’adoption d’un enfant a toujours été perçue comme un conte de fées selon lequel les couples, qui n’ont pas eu la chance d’avoir leurs propres enfants, choisiraient de sauver la vie d’enfants abandonnés ou orphelins. Cependant, un nombre croissant d’individus adoptés dans le monde entier expriment maintenant leur mécontentement face aux arrangements qui les ont déracinés de leurs origines. Ils partagent des histoires d’identités perdues et aspirent à renouer avec leurs parents biologiques, en particulier leurs mères qui sont souvent blâmées et stigmatisées. Cet article vise à montrer que l’adoption internationale dans le cadre de la guerre du Liban ne visait pas uniquement à sauver des enfants innocents et à leur offrir de meilleures perspectives. En comparant le cas libanais à l’histoire internationale de la séparation forcée, en particulier l’expérience des peuples autochtones au Canada, cet article explore les récits partagés par les adoptés dans un effort visant à documenter l’un des aspects invisibles de la guerre civile libanaise.
27Al MAS NMR spectroscopy study of Eu2+-doped and Dy3+-co-doped SrAl4O7
Authors: Misevičius Martynas , Dagys Laurynas , Maršalka Arūnas , Kristinaitytė Kristina , Balevičius Vytautas
Published: April 2020

The Eu2+-doped strontium aluminate SrAl4O7 samples have shown the blue-green persistent luminescence at 490 nm while the co-doping with Dy3+ shifts the maximum of emission to 475 nm. Undoped, 3% Eu-doped and 6% Dy-co-doped SrAl4O7 samples were prepared by the solid state-reaction method and studied by the solid-state 27Al MAS NMR applying the single pulse-acquire and Hahn-echo pulse sequences. It was shown that the Eu2+ with Dy3+ ion doping did not affect the bulk structure as well as the local Al environment in SrAl4O7. This means that large shifts of the emission maximum cannot be caused by changes in the local environment upon the co-doping of SrAl4O7:Eu2+ with Dy3+. However, the spectral features observed in the range between the signals of 4- and 6-coordinated Al (20–40 ppm) indicate that certain phase imperfections are present in all studied samples, and most probably amorphous/glassy domains were formed. Note that such amount of phase impurities was not detected by standard XRD or FTIR methods. This has revealed the 27Al MAS NMR technique to be a very effective tool monitoring the phase perfectness in series of strontium aluminate samples.
Effect of vertebral degeneration on the instability of spine
Authors: Chabarova Olga , Kačianauskas Rimantas , Alekna Vidmantas
Published: April 2020

Insufficient exploration of the dependence between diseases of degenerative bones and the range of motion (ROM) during torsion, flexion and lateral bending limits further understanding about the lumbar biomechanics and treating of the lumbar related dysfunction. The objective of this study was to determine the effect of vertebral degradation on the instability of spine 2 motion L2–L4 segments during torsion, flexion and lateral bending by the finite element method (FEM). Three different 3D FE models comprising the healthy state and the degradation of trabecular bone and cortical bone were developed. Nonlinear numerical analyses of lumbar spine stability discovered that osteoporotic degradation can lead to critical segmental ROM and intervertebral shearing values, which results in the loss of spine stability for the case of flexion loading. Instability is caused by microscopic changes in the thickness of cortical shell. This analysis of the intervertebral shearing and ROM may be further used to diagnose such translation abnormalities like hypomobility or hypermobility.
Les fortifications occidentales de Porsuk, restitution et modélisation des états les plus anciens
Authors: Tibet Aksel , Laroche-Traunecker Françoise
Published: April 2020

The aim of this paper is to propose a reconstruction of the evolution and of the appearance of the Porsuk fortifications on the western part of the site. The so-called ‘Hittite’ period, which has been chosen for this study, corresponds to the earliest phases of the site – Porsuk VI and V – with two successive destruction layers and three stages of construction – VI, Vb and Va. Considering the highly speculative interpretation of the latest status of phase V, its remains being seriously disturbed by the Iron Age reoccupation, it has been decided to limit our study to Phase VI and to Phase V before its first destruction. Reconstruction hypothesis given in this contribution have been conceived with the help of 3D computer program based on the archaeologists’ observations and a detailed documentation of the remains.
Tyana Bizantina: circolazione e tesaurizzazione monetale
Authors: Asolati Michele , Crisafulli Cristina
Published: April 2020

Excavations at Tyana by the archaeological mission of the University of Padua (Italy) under the direction of Guido Rosada revealed a large amount of numismatic material now reached six hundred units. Most of the coins were minted in the Byzantine era, especially between the 6th and the middle of the 7th century: they are isolated finds, but one can document for the first time in Cappadocia bronze coins treasure from the 6th or 7th century. They illustrate the network of relationships and the degree of economic development of the former center of Tyana, on the eve of the Arab invasion.
Autun/Augustodunum, cité des Éduens
Authors: Labaune Yannick , Kasprzyk Michel
Published: April 2020

Les campagnes de fouilles de ces quinze dernières années permettent désormais de mieux cerner les modalités de la fondation d’Autun/Augustodunum et son développement à l’époque julio-claudienne. Malgré d’indéniables avancées scientifiques, la chronologie et les formes d’occupation se précisant peu à peu, on constate que seule une petite superficie de l’espace urbain inégalement répartie, de l’ordre de 1 %, a bénéficié jusqu’à présent d’une fenêtre de fouille sur les niveaux les plus précoces. Ce bilan est donc amené à évoluer dans les prochaines années, au fil des fouilles préventives qui s’attardent désormais plus volontiers sur les niveaux intra muros les plus anciens, mais également dans le cadre des campagnes de fouilles programmées à l’emplacement du sanctuaire périurbain de la Genetoye, dont le substrat laténien a récemment été mis en évidence. Il conviendra notamment de s’interroger sur le rôle éventuel joué par ce secteur lors du transfert de chef-lieu de Bibracte à Autun.

Published: April 2020

Le dossier relatif à la ville antique de Langres s’est récemment enrichi de données qui ont permis de reconsidérer la question de la mise en place de la capitale des Lingons. Les informations nouvelles alimentent en particulier le dossier relatif aux antécédents celtiques de la ville romaine. Les recherches menées dans le cadre de l’archéologie préventive ont livré des témoins de travaux urbanistiques importants réalisés à l’époque augustéenne, à l’emplacement même de l’oppidum gaulois. Les prospections et les études de mobilier réalisées au nord de Langres ont livré des renseignements intéressant la capitale lingonne et son environnement, en particulier sur les modalités d’émergence et de développement du pôle urbain langrois, depuis La Tène moyenne et durant la période julio-claudienne.
Trèves/Augusta Treverorum, cité des Trévires : les premiers temps de la ville
Authors: Morscheiser-Niebergall Jennifer
Published: April 2020

La naissance de la ville de Trèves, Augusta Treverorum, est généralement associée à l’édification du pont de bois sur la Moselle, en 18-17 av. J.-C. Une analyse méticuleuse du mobilier associé aux premiers niveaux de la voirie montre que le réseau viaire ne semble pas avoir été construit avant l’horizon céramique de Haltern, autour du tournant de l’ère. Même s’il existe dans la vallée des traces d’occupations humaines antérieures à cette époque, notamment le camp du Petrisberg, clairement associé à l’épisode de la grande révolte trévire de 29 av. J.-C., la naissance matérielle de la ville doit être chronologiquement dissociée de la datation du pont.
Cologne, oppidum des Ubiens : l’urbanisme augustéen
Authors: Schäfer Alfred
Published: April 2020

Implanté par initiative impériale sur le territoire fraîchement attribué au peuple transrhénan des Ubiens, l’Oppidum Ubiorum (future Cologne) prend, dès sa naissance, sans doute dans la dernière décennie avant notre ère, l’allure d’une capitale provinciale. Son urbanisme typiquement romain, son faciès culturel sont caractéristiques d’une population d’origine italienne et non pas locale. L’armée romaine a probablement joué un rôle majeur dans l’émergence de ce pôle provincial, situé au sein d’un territoire fertile et bien relié au reste de la Gaule par les grandes rocades du réseau routier augustéen. Ville romaine et non pas indigène, Cologne allait par la suite connaître un destin exceptionnel et jouer un rôle majeur dans l’organisation et l’économie de la province de Germanie.

Published: April 2020

O desempenho técnico-tático é fundamental para a vitória no voleibol, deste modo, é importante identificar indicadores associados com a vitória no set. Assim, o objetivo do presente estudo foi identificar e associar os coeficientes de performance técnico-tático em função do resultado do set no voleibol feminino escolar. Participaram do estudo atletas escolares, com idade entre 12 e 14 anos. Foram analisados 27 jogos, resultando em 57 sets, 7194 ações (saque= 2380; recepção de saque= 2157; levantamento= 1358; e ataque= 1299). Posteriormente, foi calculado o coeficiente de performance por ação e set. Utilizou-se de regressão logística binária, para verificar a associação dos coeficientes de performance com a vitória do set. O coeficiente de performance de saque classificado como “bom” mostrou-se como principal preditor de vitória no set (OR = 29,46), seguido por levantamento “bom” (OR= 15,87), e ataque “bom” (OR= 7,32). O saque é o principal preditor de performance no presente estudo, seguido pelo levantamento e ataque. Esses resultados sugerem que o saque deve ser priorizado no treinamento, já que aumenta as chances de vitória no set.

Published: April 2020

A partir da análise documental de 210 relatórios dos Jogos Escolares da Rede Pública da Bahia (JERP), este estudo teve por objetivo descrever a evolução histórica do JERP de 2009 a 2017, considerando as modalidades comuns e inovadoras ofertadas, número de escolares, número de escolas, número de professores e recursos financeiros descentralizados. Verificamos que as modalidades inovadoras foram numericamente superiores às modalidades comuns e apresentaram maior diversificação das práticas esportivas; o número de escolares, escolas e professores na primeira etapa dos jogos (dentro das escolas) foi superior a terceira etapa (regional), além de aumentar ao longo dos anos em ambas as etapas; e que o valor financeiro descentralizado tendeu a crescer no período histórico analisado. Concluímos que o JERP se apresenta como uma oportunidade dos alunos vivenciarem diferentes modalidades esportivas, entretanto esta oportunidade é ressaltada apenas na primeira etapa. Em relação aos recursos financeiros descentralizados para o JERP, parece não haver planejamento prévio com relação a proporção destes recursos e a proporção de escolares participantes deste programa. Sugerimos maior concentração de recursos em competições locais do que estaduais, uma vez que atendem mais crianças e jovens e favorecem a valorização da diversificação de modalidades e respeito à cultura esportiva local.
Teacher self-efficacy and its sources in physical education teaching training experiences
Authors: Iaochite Roberto Tadeu , Costa Filho Roraima Alves da
Published: April 2020

During initial training, aspiring teachers should learn how to deal with the high cognitive, emotional and behavioral demands generated by teaching. At the same time, they need to develop and strengthen their personal belief that they will be capable of handling said challenges. In the physical education context, these demands can be even more challenging, given the environment and conditions in which classes are taught. This study aimed to analyze teacher self-efficacy belief as to teaching physical education, and its construction from situations experienced during school-based teacher training. A total of 87 future teachers (54% women; average age = 21.8) from a public university in the state of São Paulo completed a sociodemographic questionnaire and the Teachers’ Sense of Efficacy Scale (Tschannen-Moran & Woolfolk Hoy, 2001). To describe sources of teacher self-efficacy, reflective portfolios composed as the final product of a supervised internship were analyzed. The student teachers showed moderate to high self-efficacy belief, which was primarily supported by teaching experiences and verbal persuasions. The relevance of teacher self-efficacy for teacher training, particularly in physical education early training processes, is discussed.

Published: April 2020

The present study aimed to evaluate the acute behavior of the brachial artery resistance index (BARI) and popliteal artery resistance index (PARI) in response to low intensity strength exercises involving small (SMG) and large muscle groups (LMG) performed with and without blood flow restriction. Eleven men (age 23 ± 3.29 years) underwent a four-arm, randomized, cross-over experiment: Small muscle group exercise (SMG), small muscle groups with blood flow restriction (SMG+BFR), large muscle groups (LMG) and large muscle groups with blood flow restriction (LMG+BFR). The behavior of BARI and PARI was evaluated at rest, immediately after exercise, and at 15 and 30 minutes during recovery. Data analysis showed a significant reduction of the BARI from rest to post-exercise only in the protocols involving SMG, regardless of the BFR (p <0.05). Protocols involving LMG, with or without BFR, did not affect PARI (p> 0.05), but were efficient to promote significant increases in BARI (p <0.05) immediately after exercise. Our findings indicate that the exercises involving SMG, regardless of BFR, are efficient to promote local vasodilatation (brachial artery), but without systemic effects. None of the analyzed protocols affected the PARI behavior.
SÍMBOLOS DE CHRISTOFFEL VIA FORMALISMO LAGRANGEANO
Authors: Nascimento Luciano
Published: April 2020

Neste trabalho é utilizado o formalismo de Euler-Lagrange para descrever as equações geodésicas baseadas em derivadas covariantes para obtenção dos Símbolos de Christoffel. Os Símbolos de Christoffel e as demonstrações destas relações servirão para resolução de vários problemas em teoria da relatividade geral, teoria da elasticidade, mecânica dos fluídos e eletromagnetismo. Utilizam-se os símbolos de Christoffel sempre que cálculos práticos que implicam geometria devam ser realizados, pois permitem que cálculos muito complexos sejam realizados sem confusão. Inversamente, a notação formal, sem índices, para a conexão de Levi-Civita é elegante, e permite que os teoremas sejam estabelecidos de um modo breve, porém são quase inúteis para os cálculos práticos.

Published: April 2020

Baseado na crescente e expressiva quantidade de resíduos sólidos gerados pelo atual modelo de desenvolvimento, a busca pela produção de concretos que sigam as diretrizes e os conceitos de sustentabilidade tornou-se um grande desafio para o âmbito da construção civil. Nestas diretrizes estão inseridas a reciclagem e a reutilização, ambas se apresentam como alternativas sustentáveis para reduzir os danos acarretados ao meio ambiente. Neste contexto, o objetivo desta pesquisa foi analisar a substituição parcial da areia natural por resíduos de borracha de pneu de diferentes malhas, sendo a mais fina malha 40 e a mais grossa de malha 10. Os corpos de provas foram submetidos aos ensaios de resistência à compressão, tração por compressão diametral nas idades de 3, 7, 28 e 91 dias e módulo de elasticidade dinâmico nas idades de 28 e 91 dias. Verificou-se então que todos os concretos em ambos estados, fresco e endurecido atenderam aos parâmetros normativos e surgem como uma alternativa um tanto quanto promissora no quesito sustentabilidade.

A qualidade da água vem sendo uma preocupação crescente devido principalmente ao aparecimento de contaminantes emergentes nas águas de consumo, o que tem provocado pesquisas de diferentes tecnologias e processos para seu tratamento. Portanto o objetivo deste trabalho foi analisar a adsorção da tetraciclina utilizando uma matriz de poliuretano expandido com carvão ativado obtido a partir da casa de banana. O carvão ativado foi obtido pelo processo químico e físico e a matriz foi desenvolvida com diferentes frações do carvão. Com as matrizes, foi realizado um teste de adsorção com concentrações diferentes de Tetraciclina (10 mg/L e 30 mg/L). Através dos resultados obteve-se uma eficiência de remoção de tetraciclina de 22,9% para a concentração de 10 mg/L e 21,4% para a concentração de 30 mg/L para a matriz de 10% de carvão. Uma análise da eficiência do carvão ativado foi realizada, e obteve-se uma eficiência de aproximadamente de 98% para ambas as concentrações de tetraciclina estudas. Apesar da matriz não apresentar resultados satisfatórios na adsorção, a casca de banana provou ser um bom meio de obtenção de carvão ativado alternativo, utilizando-se de um resíduo industrial para adsorção de fármacos, como a tetraciclina.

Published: April 2020

This paper emphases on the effect of various machining constraint on surface roughness and material removal rate in turning SiC reinforced Al alloy composite through taguchi orthogonal array based experimental analysis which has been further optimized using principal component analysis (PCA). Experimental investigation has been conducted under minimum quality lubricant (MQL) cutting environment. Palm oil has been used as lubricant where flow rate and pressure were kept at 120 ml/hr and 8 bar. The whole experiment has been designed using L25 orthogonal array having three input parameters and five different level to measure surface roughness and material removal rate. Taguchi S/N ratio-based optimization has been implemented where smaller the better criteria has been used for surface roughness whereas larger the better criteria has been used for material removal rate. From Analysis of variance, it is observed that cutting speed and feed rate are the most prominent factor for surface roughness. Nevertheless, Depth of cut and cutting speed are the most dominant factor for material removal rate. While comparing the predicted output values with experimental values, MAPE value is found in the range of 0.23 % for surface roughness and 0.045 % for material removal rate which is in very much tolerable range. Correlation coefficient value for experimental values of the resultant output is 0.98286 and 0.99869 respectively which signifies the effectiveness of the whole experiment. Subsequently, machining parameters were optimized using PCA technique. To attain satisfactory response values, depth of cut, cutting speed and feed rate need to be at 0.85 mm, 396 m/min and 0.16 mm/rev respectively. By applying the model, surface roughness of 0.7257 μm and MRR of 53856 mm3/min can be obtained.

An Analysis of Equity Among Policy Solutions for Traffic Congestion
Authors: Steakley Ethan
Published: April 2020

The emergence of ride-hailing in the United States has brought forth new issues for its cities, particularly a large influx of traffic congestion. Today, several cities have introduced distinct ideas to solve congestion issues while debating their implications for equity. This paper examines the equity implications of traffic congestion in America'•s cities by comparing a flat tax rate on ride-hailing to various road pricing mechanisms using specific evaluative criteria, including transportation access and vertical equity. This paper begins with an overview of ride-hailing in the United States and the congestion problem it poses for cities, then reviews the literature around congestion and equity, describes and assesses the equity of a flat tax rate and road pricing, and ends with broad implications resourced from the literature for future policy.

The COST-UTILITY ANALYSIS OF FOUR CHELATION REGIMENS FOR Β-THALASSEMIA MAJOR: A CHINESE PERSPECTIVE
Authors: Li Jialian
Published: April 2020

Background: The four most commonly used chelation regimens for β-thalassemia major patients in China are a combination therapy of deferoxamine and deferiprone (DFO+DFP), deferoxamine(DFO) monotherapy, deferiprone(DFP) monotherapy and deferasirox(DFX) monotherapy. Such patients use iron chelators their whole lives, resulting in enormous treatment costs. This study analyses the cost-utility of these four regimens from the Chinese healthcare system perspective.

Methods: A Markov decision model was used over a 70-year time horizon and was populated using clinical data from a systematic literature review. We obtained utility data from local and previous research. Costs were estimated using Chinese national sources.

Results: From the base-case analysis results, DFP was the most cost-effective chelation regimen, followed by DFO+DFP, DFO and DFX. DFP had a 99.60%, 78.10% and 64.40% likelihood of being cost-effective versus DFX, DFO and DFO+DFP, respectively, at a payment threshold of 193,932.00 CNY/QALY.

Conclusions: DFP was the most cost-effective chelation regimen for β-thalassemia major patients, followed by DFO+DFP, DFO and DFX. Using DFP as the primary treatment regimen may potentially result in cost-savings and QALY gains for the Chinese healthcare system. To increase these benefits, the Chinese government and clinicians should lower drug costs, increase drug utility and reduce mortality and morbidity. Changes in influential parameters easily affect the results of DFO+DFP versus DFP and of DFP versus DFO; clinicians should focus on such parameters and adjust the regimens accordingly.

Published: April 2020

Background: Several strategies have been developed to reduce collagen degradation in the adhesive interface. Epigallocatechin3gallate (EGCG) has the ability to stabilize collagen, and it is effective in microbial reduction. Aims and Objectives: The objective of the present study was to evaluate the antimicrobial potential, water sorption (WS), and solubility of a universal adhesive incorporated with EGCG at concentrations of 0.02%, 0.1%, and 0.5%, respectively. Materials and Methods: Atotal of 40 specimens of composite resin disks, to which the adhesives were applied, were divided into four groups: control (without EGCG), 0.02%, 0.1%, and 0.5%. The specimens were submitted to an in vitro cariogenic challenge, inoculated with Streptococcus mutans for 3 days for biofilm formation. The generated biofilm was collected, and the colonyforming units were established. For the solubility test, the specimens using the adhesive were divided into the same groups mentioned previously (n = 10). Adhesive models were made following an ISO standard for sorption and solubility tests. Microbiological data were submitted to the analysis of variance (ANOVA), followed by the Tukey test (P < 0.05). ANOVA was used to evaluate WS and solubility, and comparisons were made by post hoc analysis by the Student–Newman–Keuls method (P < 0.05). Results: A statistical difference was observed regarding the antimicrobial potential between the groups without and with EGCG at 0.5% (P = 0.03). EGCG 0.5% presented the highest values of solubility and WS (P < 0.01 and P = 0.009, respectively). Conclusion: The addition of 0.5% EGCG was capable of inhibiting biofilm formation; however, it caused significant alteration of the solubility and sorption of the adhesive.

Published: April 2020

INTRODUCTION: Diabetes mellitus is a common disease of the human body caused by a group of metabolic disorders where the sugar levels exceed a prolonged period, and that is very high than the usual time. It not only affects different organs of the human body but also harms a large number of the body system, in particular the blood veins and nerves.OBJECTIVES: Early predictions of this phenomenon can help us to control the disease and also to save human life. For achieving the goal, this research work mainly explores various risk factors such as kidney complications, blood pressure, hearing loss, and skin complications related to this disease using machine learning techniques and make a decision.METHODS: Machine learning techniques provide an efficient result to extract knowledge by constructing predicting models from diagnostic medical datasets collected from 200 diabetic patients from the Medical Centre Chittagong, Bangladesh using 16 attributes. Obtaining knowledge from such data can be useful to predict diabetes. In this work, we perform four popular machine learning algorithms, such as Support Vector Machine (SVM), Naive Bayes (NB), K-Nearest Neighbour (KNN) and C4.5 Decision Tree (DT), on adult population dataset to predict Diabetes Mellitus.RESULTS: C4.5 Decision Tree performs better than other algorithms for predicting diabetes with 73.5% accuracy, 72% F-measure, and 0.69 of AUC (area under ROC curve). Besides, we determine the correlation between different risk factors of Diabetes Mellitus. The highest correlation is 0.81 for blood pressure (Hypertension) complications with diabetes.CONCLUSION: In this study, both positive and negative correlation has been established between the various risk factors and diabetes. There is a positive correlation for predicting kidney complications (Nephropathy) and blood pressure (Hypertension) complications and a negative correlation at predicting hearing loss and skin complications (diabetes dermopathy) from diabetic patients. It helps a patient to be aware of the risk factors related to diabetes.

Turkey-Africa Relations: Opportunities and Challenges
Authors: Gamawa Yusuf Ibrahim
Published: April 2020

The Continent of Africa had been of great importance to many Countries outside Africa, Since the begining of the slave trade when European slave merchants invaded Africa and estalished the trade in human beings, which forced the migration of millions of Africans to America and the West Indies.

This article discusses the concept of scalability as it relates to business and non-scalable components of business process as well as the importance of being scalable.

Price-Swinging Stock Market Fundamentals: Nexus and Contemporary Features
Authors: Agundu Prince Umor C. , Wula James T. , Musa Usman Mamuda
Published: April 2020

The factors which determine stock prices in capital markets are many and diverse; hence researchers in the academic fields of accounting and finance intermittently undertake to track them with contextual emphasis. From the philosophical basics to the more rigorous econometric dispositions, analysts in different schools of thought had ventured in this regard and came up with divergent outcomes. Some factors did commonly appear for most stock markets, while various conditions surrounding the respective scenes accounted for environmental dynamics.  This reinforces the truism that each market has acclimatized rules and regulations, country peculiarities, and investor typologies; all of which provide basis for uniqueness. In this conceptual analysis, the factors that feature as dominant determinants of stock prices are Earnings per Share (EPS), Dividend Per Share (DPS), and Price-Earnings Ratio (P/ER); among which the last is the most and not the least. It further attests to the prevailing value relevance of financial statement information emanating from corporate accounting reports; hence the imperativeness of stock market regulators sustaining the rules that make for adherence to best practices. The alternative to informational reliability is institutional fragility; because when investors’ confidence erodes, liquidity squeezes, efficient markets crashes, and in turn, investors withhold investments. It, therefore, requires market regulatory/administrative mechanisms to be focally directed at enhancing reportorial compliance and compelling higher due diligence, accountability and responsibility in line with international standards.

Authors: Allahyarifard Mahmoud , Karimzadeh Mostafa , Falahi Mohammad Ali , Meidani Ali Akbar Naji
Published: April 2020

Simultaneous making policy of interest rates, exchange rates and capital accounts can be extended to trilemma theory, contrary to its earlier theories, provided that the imbalances of the private sector, the government and the capital account adjusted through the policy variables such as the government expenditures, the interest rates on domestic deposits, the interest rates on domestic loans, effective exchange rates, foreign prices and foreign interest rates. On the other hand, the components of the extension of trilemma theory in the form of internal and external imbalances affect the exchange rate. In other words, if the real sector markets of the economy are not cleared through the aforementioned trilemma components, and policy variables, internal and external imbalances will be affected by opposite direction of net domestic assets (ΔNDA) and net foreign assets (ΔNFA) of the banking system. This is in accordance with the fundamental principles of the monetary approach balance of payments and exchange rate. Policy variables do not put pressure on the unofficial exchange rate as long as they have the same effect on the net changes in the domestic and foreign assets of the banking system. The purpose of this study is to consider the effect of internal and external imbalances on exchange rate through the simultaneous equations system, generating impulses in policy variables, and examining reactions in Iranian economy. In this paper, the monetary exchange rate determination model is analyzed and examined by using the extension of trilemma theory for macroeconomic data of Iran in the form of internal and external imbalances. The results of this study suggest that policy variables can stabilize the unofficial exchange rate (with other conditions being constant) through trading off internal and external imbalances. Thus, the economic policymaker can, while independently policing interest rates, capital accounts and government expenditures and other policy variables in this research, maintain exchange rate stability as a strategic variable and anchor the general level of prices.

Macroeconomics Needs Fresh Methodology of Theorization
Authors: Bidabad Bijan
Published: April 2020

In this paper, we try to analyze the macroeconomic reasoning in different methodological issues. Subsequently, we try to touch some current macroeconomic debates on aggregations, relations, monetary and real sectors analyses. We assess that what we know about the behavior of macroeconomic variables is just our understanding from empiricism, and we have rarely found the laws of linkages among macroeconomic variables. We also conclude that successive theories have an intuitional foundation. It seems that to improve macroeconomic theories and policies, we need to be redirected to basic philosophical thinking about the macroeconomic theoretical foundation and try to rebuild a new concrete base for macroeconomics.
