Published: May 2022

O voleibol se caracteriza por exigir determinadas qualidades psicológicas dos jogadores tais como: autoconfiança, determinação, disposição e força de vontade. Tem que dominar todo um sistema de hábitos motores, em diferentes combinações, com um alto grau de precisão e de diferenciação dos movimentos e com uma rápida modificação de formas de movimento, em termos de ritmo e velocidade, em ataques e defesas. O desempenho esportivo no voleibol envolve muito mais do que uma habilidade física, técnica e tática, envolve também qualidades psicológicas importantes. O objetivo deste estudo foi investigar o papel representativo dos atletas levantadores das equipes de voleibol e verificar a predominância significativa entre os aspectos físicos, técnicos, táticos e pensamento coletivo dos técnicos. Fizeram parte do presente estudo, 14 técnicos, com predominância de 13 técnicos do sexo masculino, com média de idade em um intervalo de 35 a 45 anos e tempo de experiência como treinadores destas equipes, entre 10 a 20 anos  em  média.  Os  treinadores foram entrevistados  com uma única questão geradora que permitiu respostas abertas: “Para você, quais são as características que um levantador deve ter para ser um atleta de alto rendimento e chegar a uma seleção nacional?”. “Comente sua resposta”. As entrevistas foram gravadas em áudio e posteriormente transcritas na íntegra. Os resultados foram analisados seguindo-se o Modelo do Discurso do Sujeito Coletivo (DSC), finalizando com a construção do DSC para cada grupamento identificado em cada etapa do Modelo, redigido na primeira pessoa do singular como se uma única pessoa estivesse falando. Com base nos resultados obtidos neste estudo, As características de comportamentos das atletas que  atuam  na  posição de levantador  estariam  fundamentalmente  associadas  com  os  aspectos  psicológicos,  quando comparados com os aspectos físicos, técnicos e táticos.

Published: May 2022

O envelhecimento saudável é uma condição a ser atingida e almejada por todos os segmentos da sociedade, envolve criar políticas intersetoriais que promovam modos de viver mais saudáveis em todo mundo. A noção de que uma boa qualidade de vida envolve a adoção de comportamentos promotores de saúde a exemplo da prática de atividade física no cotidiano e no lazer, está fortemente propagada no imaginário social. O comportamento ativo é cada vez mais estimulado e percebido como uma ação estratégica para o cuidado com a saúde ao longo de toda a vida. Entretanto, ao analisar a mudança comportamental de quem envelhece, significa refletir sobre a possibilidade de ganhos substanciais em qualidade de vida com a manutenção da autonomia e do autocuidado na velhice. Neste trabalho, analisa-se os conceitos de autonomia e autocuidado de egressas em projeto de extensão e a relação entre a manutenção e a adoção da prática de atividade física após a participação no projeto. Para tanto, a investigação transcorreu por meio da abordagem qualitativa com um grupo de sete mulheres idosas participantes de projeto de extensão. A produção dos dados foi obtida mediante o uso do grupo focal, o material produzido foi submetido à análise temática segundo os procedimentos de codificação proposto por Saldaña. Os resultados demonstram que os conceitos de autocuidado e autonomia das participantes egressas favorecem a manutenção e a adoção da prática de atividade física bem como, ações promotoras de saúde. Observou-se ainda, que para as participantes os conceitos de autocuidado e autonomia estão intimamente relacionados com a história de vida de cada participante e a construção social do papel da mulher como promotora do cuidado familiar. O grupo enfatiza a velhice como um processo de autoconhecimento e liberdade para o cuidado de si desde que ações de cunho educacional sejam direcionadas a esta população.

Unequal allocation of overt and covert attention in Multiple Object Tracking
Authors: Hadjipanayi Veronica , Shimi Andria , Ludwig Casimir J. H. , Kent Christopher
Published: May 2022

In many real-life contexts, where objects are moving around, we are often required to allocate our attention unequally between targets or regions of different importance. However, typical multiple object tracking (MOT) tasks, primarily investigate equal attention allocation as the likelihood of each target being probed is the same. In two experiments, we investigated whether participants can allocate attention unequally across regions of the visual field, using a MOT task where two regions were probed with either a high and low or with equal priority. Experiment 1 showed that for high-priority regions, accuracy (for direction of heading judgments) improved, and participants had more frequent and longer fixations in that region compared with a low-priority region. Experiment 2 showed that eye movements were functional in that they slightly improved accuracy when participants could freely move their eyes compared with when they had to centrally fixate. Replicating Experiment 1, we found better tracking performance for high compared with low-priority regions, in both the free and fixed viewing conditions, but the benefit was greater for the free viewing condition. Although unequal attention allocation is possible without eye movements, eye movements seem to improve tracking ability, presumably by allowing participants to fixate more in the high-priority region and get a better, foveal view of the objects. These findings can help us better understand how observers in real-life settings (e.g., CCTV monitoring, driving) can use their limited attentional capacity to allocate their attention unequally in a demand-based manner across different tracking regions.

John Gerson and the Foundations of Mystical Theology
Authors: Vermander Benoît
Published: May 2022

Among other contributions, Jean Gerson (1363-1429) has played a decisive role in establishing spiritual theology as an experimental science, the foundation and process of which are independent from the ones of dogmatic theology, even if their results need to eventually coincide. Based, as all works in the field, on Pseudo-Dionysius, Gerson’s De theologia mystica (written between 1402 and 1423) developed an epistemology of mystical knowledge, itself grounded upon an anthropology describing how humankind’s cognitive and affective powers operate together. Gerson’s work played a major role in the development of French, and more largely, modern approach to mysticism.

The same Origin and different Roads: the old and recent hatred between Catholicism and Protestantism in Modern China
Authors: Guo Jianbin
Published: May 2022

In modern China, with the signing of a series of unequal treaties, there were constant disputes between Catholicism and Protestantism in order to fight for missionary authority, missionary regions and discourse power. As a modern Catholic Chinese Jesuit, Li Wenyu（1840-1911） had written many works on the relationship between the two denominations to defend for Catholicism. In the terms of the content, most of the works are the continuation of the sectarian argument triggered by the Reformation, concentrating mainly on the discussion of doctrines, rituals, the Bible and so on. However, few researches are concerned about new missionary issues such as Missionary cases or a type of inseparable connection between missionaries and Western Powers and they are just a kind of passive response to other people's queries. In the way of Apologetics methods, he once used traditional Chinese culture to explain the doctrines of Catholicism whereas it only occupied a little part. On most occasions, he interpreted doctrines through the Bible directly. By reviewing the relevant works of him, it can be seen that the modern Chinese Catholicism represented by Li Wenyu paid more attention to the enmities caused by differences in beliefs or doctrines instead of new problems arose in missionary work.
The Economic Ethic in Chinese Society: Differences from and Similarities to the Western Economic Ethic from the Perspective of Social Cooperation
Authors: PENG Rui
Published: May 2022

Using game theory and transaction cost theory, religion or the religious ethic is converted to a system that provides ethical support and interpretation for various types of social cooperation and supports their equilibrium either partially or completely. From the perspective of the social cooperation ethic, the economic ethic of modern society may be viewed as a “partial equilibrium” that comprises the horizontal cooperation ethic (commerce or market) and the vertical cooperation ethic (the internal power in an enterprise). In this regard, Weber strongly interpreted the causes and processes of the differentiation and independence of the modern economic ethic of the West as “partial equilibrium” from “overall equilibrium.” However, the economic ethic in Chinese society has been different and has always maintained a close association with “overall equilibrium,” and its expression and symbolism have undergone a change in process from the local god of Sheji(社稷神，god of state) to local Chenghuang gods(城隍神, city gods) to nationwide popular general gods.

Published: May 2022

Introduction: Thyroidectomy is the treatment of choice for non-toxic compressive Multinodular Goiter (MNG). However, when surgery is contraindicated, other therapeutic options should be evaluated. In this case report, non-surgical therapeutic possibilities are reviewed, and the results obtained with Radioiodine Therapy (RAI) after stimulating with Recombinant Thyroid-Stimulating Hormone (rhTSH) are described. Case report: A 92-year-old patient with multiple comorbidities, non-toxic MNG, and symptomatic compression of the trachea and esophagus. Accordingly, RAI was chosen due to the high surgical risk. Initially, pre-treatment with methimazole was performed to increase TSH, which was interrupted due to drug hepatitis. Then, RAI was chosen in the post-stimulus with a low dose of rhTSH, with significant and early reduction of goiter and symptoms. Discussion: Although total thyroidectomy is the treatment of choice for non-toxic and symptomatic intrathoracic MNG; it does present risks, especially in patients with multiple comorbidities. Thus, interest in less invasive techniques is increasing. Thermal radio-ablations exhibit satisfactory results, however it is still an inaccessible technique. Radioiodine is an effective treatment option subsequent to the use of rhTSH or hypothyroidism methimazole-induced. RhTSH and methimazole can increase the level of radiation absorbed by the gland, which can lead to a reduction in the required I-131 dose. Conclusion: It is possible to mitigate the symptoms and improve the quality of life of patients with non-toxic and symptomatic MNG and multiple comorbidities, without surgical intervention. In this case report we describe alternatives to surgical intervention and show the effectiveness and safety of RAI along with rhTSH in the management of MNG.

Authors: Abu Ali Khaled Ali
Published: May 2022

Background: Hepatitis B is a vaccine-preventable liver infection caused by the Hepatitis B Virus (HBV). Hepatitis B (HB) is spread when blood, semen, or other body fluids from a person infected with the virus enters the body of someone who is not infected. Aim of the study: To identify the efficacy of hepatitis B immunoglobulin with hepatitis B vaccine versus hepatitis B vaccine alone to prevent the HB vertical infection. Method: An quasi-experimental clinical trial was used, 114 new born were included in the control group and 114 newborn were included in the intervention group, both groups were given HB vaccine but the control group HB vaccine combined with hepatitis B immunoglobulin, all of the subjects were born to mother positive HBV and negative HBeAg indicating inactive HBV cases. Results: Revealed that the used regimens were effective to interrupt mother to child transmission of HBV, the geometric mean titration was higher (207.64 IU/L) among the infants were included in the control group versus (180.87 IU/L) to the infants were included in the intervention group, non-protective rate was 6.6%, relative risk 2.63. Conclusion: Hepatitis B vaccine alone is not inferior to HB vaccine combined with HBIG to prevent the infection and both regimens were effective.

Published: May 2022

How microflares behave and differ from large flares is an important question in flare studies. Although they have been extensively investigated, microflares are not fully understood in terms of their detailed energy release processes and the role of energetic electrons. A recent study on an A-class microflare suggests the existence of a nonthermal component down to 6.5 keV, indicating that accelerated electrons play an important role in microflares, as in large flares. Here, we revisit this event, and present a comprehensive, quantitative analysis of the energy release and plasma heating processes. Using careful differential emission measure (DEM) analysis, we calculate the thermal X-ray fluxes. By subtracting this multithermal component from the observed data, we confirm the existence of the remaining nonthermal component. In addition, we analyze the clear evaporation process and report the first imaging evidence for a low-energy cutoff of energetic electrons in EM maps of >10 MK plasma, which first appeared as two coronal sources significantly above the chromospheric footpoints. Detailed calculations of electron transport, based on the electron parameters and the evolution of loop dynamics, provide strong evidence of a beam-driven plasma heating process with a low-energy cutoff consistent with that derived independently from DEM analysis. This study reveals the important role of electron thermalization and low-energy cutoffs in the physical processes of microflares.

Strong galactic winds are ubiquitous at z ≳ 1. However, it is not well-known where inside galaxies these winds are launched from. We study the cool winds (∼104 K) in two spatial regions of a massive galaxy at z = 1.3, which we nickname the “Baltimore Oriole’s Nest.” The galaxy has a stellar mass of 1010.3±0.3
M
⊙, is located on the star-forming main sequence, and has a morphology indicative of a recent merger. Gas kinematics indicate a dynamically complex system with velocity gradients ranging from 0 to 60 km s−1. The two regions studied are: a dust-reddened center (Central region), and a blue arc at 7 kpc from the center (Arc region). We measure the Fe ii and Mg ii absorption line profiles from deep Keck/DEIMOS spectra. Blueshifted wings up to 450 km s−1 are found for both regions. The Fe ii column densities of winds are 1014.7±0.2 cm−2 and 1014.6±0.2 cm−2 toward the Central and Arc regions, respectively. Our measurements suggest that the winds are most likely launched from both regions. The winds may be driven by the spatially extended star formation, the surface density of which is around 0.2 M
⊙ yr−1 · kpc−2 in both regions. The mass outflow rates are estimated to be 4 M
⊙ yr−1 and 3 M
⊙ yr−1 for the Central and Arc regions, with uncertainties of one order of magnitude or more. The findings of this work and a few previous studies suggest that the cool galactic winds at z ≳ 1 might be commonly launched from the entire spatial extents of their host galaxies, due to extended galaxy star formation.
Yellow Post-asymptotic-giant-branch Stars as Standard Candles. I. Calibration of the Luminosity Function in Galactic Globular Clusters
Authors: Ciardullo Robin , Bond Howard E. , Davis Brian D. , Siegel Michael H.
Published: May 2022

We use the results of a survey for low-surface-gravity stars in Galactic (and LMC) globular clusters to show that “yellow” post-asymptotic-branch (yPAGB) stars are likely to be excellent extragalactic standard candles, capable of producing distances to early-type galaxies that are accurate to a couple of percent. We show that the mean bolometric magnitude of the 10 yPAGB stars in globular clusters is 〈M
bol〉 = −3.38 ± 0.03, a value that is ∼0.2 mag brighter than that predicted from the latest post-horizontal-branch evolutionary tracks. More importantly, we show that the observed dispersion in the distribution is only 0.10 mag, i.e., better than the scatter for individual Cepheids. We describe the physics that can produce such a small dispersion and show that, if one restricts surveys to the color range 0.0 ≲ (B − V)0 ≲ 0.5, then samples of nonvariable yPAGB stars can be identified quite easily with a minimum of contamination. The extremely bright absolute V magnitudes of these stars (〈M

V
〉 = −3.37) make them, by far, the visually brightest objects in old stellar populations and ideal Population II standard candles for measurements out to ∼10 Mpc with current instrumentation. A Hubble Space Telescope survey in the halos of galaxies in the M81 and Sculptor groups could therefore serve as an effective cross-check on both the Cepheid and tip-of-the-red-giant-branch distance scales.
Kepler Pixel Project: Background RR Lyrae Stars in the Primary Kepler Mission Field of View
Authors: Forró Adrienn , Szabó Róbert , Bódi Attila , Császár Kornél
Published: May 2022

In this paper, we describe a project we initiated to investigate individual pixels in downloaded Kepler apertures in order to find objects in the background of the main targets with variable brightness. In the first paper of this series, we discovered and investigated 547 short-period eclipsing binaries. Here we present the independent discovery of 26 new RR Lyrae stars in the Kepler background pixels obtained during the primary mission and provide continuous and precise photometry for these objects. Twenty-one of these stars were already noted by the Gaia or the Pan-STARRS survey. This new population of dominantly faint and distant RR Lyrae stars increases by 50% and complements nicely the 52 already known main target RR Lyrae stars in the original Kepler field. Despite their faintness, the four-year quasi-uninterrupted light curves of these stars allow an unprecedented view of these faint halo objects. We present an analysis of the light curves of the new RR Lyrae sample, verify their classification using Fourier parameters, and discuss the properties of these newly found pulsating variable stars. Most notably, this is the first time that such faint RR Lyrae stars have been investigated with the help of a photometric data set with outstanding cadence and precision. Interestingly, these objects share the properties of their brighter siblings in terms of subclass characteristics, additional mode content, and modulation occurrence rates.
Detecting Coconut Rhinoceros Beetle Breeding Sites Using Harmonic Radar
Authors: Moore Aubrey , Siderhurst Matthew
Published: May 2022

Coconut rhinoceros beetle, a major pest of coconut and oil palms, is causing severe economic and environmental damage following recent invasions of several Pacific islands. Population suppression and eradication of this pest requires location and destruction of active and potential breeding sites where all life stages aggregate. Three search tactics for discovering breeding sites have been used with limited success: visual search by humans, search with assistance from detector dogs, and search by tracking CRB adults fitted with radio transmitters.

Here we suggest a fourth search tactic: releasing CRB adults fitted with harmonic radar tags to locate breeding sites. Our idea is to find static end points for tags which accumulate at breeding sites, rather than active tracking of individual beetles. We plan to use commercially available hand-held harmonic radar devices. If we are successful, this technique may be useful for locating other insects which aggregate, such as hornets and other social insects.

Published: May 2022

The gas diffusion layer (GDL) in the fuel cell has been made from carbon dispersion electrochemically deposited from binchotan. We prepared GDL by spraying the ink on the surface of the conductive paper. The carbon was then characterized by its crystallography, surface functional groups and size by x-ray diffraction (XRD), FT-IR and PSA instrumentations. Cyclic voltammetry and impedance spectroscopy tests were applied to study the GDL electrochemical characters. Buble drop tests were used to obtain contact angles representing the hydrophobicity of the layer. The electrodeposition/oxidation of binchotan derived carbon dispersion has a crystalline phase in its dot structure. According to particle size analysis, carbon dispersion has an average particle size diameter of 176.7 nm, a range of 64.5–655.8 nm, and a polydispersity index was 0.138. The Nyquist plot revealed that the processes in the GDL matrices as the plot consist of two types of structures, i.e., semicircular curves and vertical (sloping) lines. The GDL electrical conductivity of Vulcan and carbon dots were 0.053 and 0.039 mho cm-1. The contact angle between conductive paper and water was 150.27°; between the gas diffusion layer and carbon Vulcan was 123.28°, and between the gas diffusion layer and carbon dispersion was 95.31°. The surface of the GDL with Vulcan is more hydrophobic than that made with carbon dispersion. In other words, the GDL with carbon dispersion is closer to hydrophilic properties. The results show that the carbon can support the gas diffusion layer for hydrophobic and hydrophilic conditions.

Published: May 2022

Depuis les années 2010 en France, une politique ciblée sur une catégorie d’« immigré » est organisée dans le cadre de la lutte contre les inégalités face au diabète. À l’appui d’un terrain ethnographique en milieu hospitalier, cet article interroge la manière dont les malades ainsi ciblés appréhendent, s’adaptent et mobilisent ces identités assignées. Après avoir analysé la manière dont les catégories ethniques sont utilisées par les soignants et modifient la trajectoire de soins, l’article revient sur comment les soignés perçoivent la relation de soins et sur les obstacles à la dénonciation des discriminations. Enfin, l’article met en évidence les limites de la possibilité d’agir des soignés tant individuellement que collectivement, participant paradoxalement au renforcement d’un ordre social inégalitaire.

Published: May 2022

With the continuous development of science and technology, especially computer technology, people need a more convenient and natural way to communicate with the machine. Language can provide people with convenient and efficient information, and speech recognition technology makes this convenience extended to the field of science and deep into human daily life. In this paper, based on human-computer speech recognition interaction system, using big data Internet of things as technical support, the contribution of intelligent social service robot to urban fire protection is studied. In this system, the user can control the action of the service robot through voice command, and the user can also realize voice interaction with the robot. Because of the continuous expansion of information technology and computer technology, human beings have entered the era of information overload, and big data technology has become a hot spot in people’s production and life. The integration of big data and Internet of things technology will make the intelligence of human society to a new level, and its development has unlimited possibilities in the future. In recent years, China’s urbanization process continues to accelerate, and the land price and house price of cities begin to rise rapidly. In order to meet people’s need, a large number of high-rise, super high-rise and underground buildings continue to increase, which not only provides us with convenience, but also makes fire safety a hot concern of the whole society. Fire fighting plays an increasingly important role in the life of urban residents. In order to greatly reduce the lack of fire safety monitoring ability, this paper uses speech recognition technology to design a city fire safety management service platform based on big data Internet of things.

“Comunicación política digital: un análisis del discurso presidencial de Mauricio Macri en Facebook durante su primer año de gobierno ”
Authors: Astigueta Martín Eugenio
Published: May 2022

El presente proyecto se inserta en el marco de un programa de investigación general orientado a estudiar la comunicación política digital de los mandatarios mundiales contemporáneos. Como caso de estudio, se analizó el uso de Facebook como canal oficial de comunicación política por parte del presidente argentino Mauricio Macri, a lo largo de su primer año de gobierno. Para ello, se implementó un análisis donde se combinaron metodologías cuantitativas y cualitativas con el propósito de indagar tanto sobre la conformación de sus contenidos, así como de las estrategias discursivas empleadas. Para dicho análisis, se recurrió a la combinación de la metodología del Análisis de Contenido con la del Análisis del Discurso Político, triangulando así, elementos teóricos del Funcionalismo con otras concepciones desarrolladas en el ámbito de la Teoría de los Discursos Sociales (Verón, 1987). El corpus de estudio estuvo constituido por una base de datos conformada por las 907 publicaciones realizadas en la cuenta oficial de Facebook del presidente Macri, durante el lapso en estudio. Para el procesamiento de los datos se recurrió a los software SPSS y Antconc. Los resultados obtenidos permiten ratificar, al menos en lo relativo al uso de Facebook, el supuesto de investigación sobre la presunta ausencia de un macro-relato unificador del discurso político del presidente Macri en un todo organizado; presentando por el contrario, un discurso fragmentado que se orientan a justificar a través de micro-relatos las medidas políticas de coyuntura adoptadas por el Gobierno. Esta fragmentación se pone de evidencia en la diversidad de tipos de formatos empleados, así como por la variedad de temáticas abarcadas por el discurso del presidente Macri en Facebook. Estos elementos, convergen en la construcción de un dispositivo de enunciación que puede caracterizarse por una lógica triple personalista, testimonial y electoralista. La caracterización de personalista se puede observar en el peso relativo de los contenidos asociados a cuestiones de la vida personal del presidente Macri, frente a los contenidos propios de la agenda política institucional. Así, se prioriza la construcción de un sujeto de enunciación centrado en la figura presidencial en sí misma, en detrimento del de la figura de un colectivo partidario. En segundo término, lo testimonial se aprecia tanto desde el plano del contenido, como desde lo enunciativo, convergiendo en una lógica propia de la “cobertura” periodística. Por último, la lógica electoralista se pone en evidencia por el peso especifico de los componentes prescriptitos y programáticos presentan frente a los didácticos y descriptivos. De esta forma, el discurso presidencial se realiza en torno a una continua promesa a futuro, a la vez que proclama una ética de la acción y la transparencia en oposición a la figura del gobierno anterior.

Published: May 2022

In 2019 there were pros and cons grew in the community regarding the repatriation of children of ex-ISIS combatants. BNPT data totaled 80 children. Those who objected were worried that these children would become radicals and would endanger the Unitary State of the Republic of Indonesia. The Presidential Staff Office proposed that for those under ten years old and orphans, the state must protect and ensure the survival of these children. Commission 1 of the DPR RI itself wanted restrictions; (1) The government should conduct an assessment involving various parties to see the extent to which these children were exposed to radicalism, (2) the government should prepare a rehabilitation and deradicalization plan, (3) the government should socialize the Indonesian people to accept the return of the children of ex-ISIS combatants. In addition, the government must also examine the perspective of international children's human rights because of the involvement of Indonesian children outside Indonesian territory.
An Empirical Evaluation of the Determinants of Property Tax Compliance Rate in Kaduna State, Nigeria
Authors: Usman Alhasan
Published: May 2022

This study examines empirically the variables that are driving property tax compliance rates in Kaduna State, Nigeria. In doing so, it relies on primary data sources. During the study, 400 respondents were targeted, but 406 completed questionnaires were analysed. The nature of the data collected necessitated employing the ordered logistic regression model to analyse the data. The result indicated that taxpayers’ satisfaction with the level of property tax digitalisation, the adequacy of property tax law, the administration of property tax and government provision of public goods are important determinants of the property tax compliance rate in Kaduna State. It further found that the average property tax compliance rate in the State is 18.32 per cent, the average satisfaction with the level of digitalisation of property tax is 39.71 per cent, the average taxpayer’s satisfaction with the adequacy of property tax law in the State is 27.68 per cent, the average satisfaction with the administration of property tax is 31.31 per cent and the average taxpayer’s satisfaction with the provisions of public goods is 58.21 per cent. The study recommends that the Kaduna State government should enact a property taxation law to adequately take care of the rate, base, time and procedures of filing and payments of the tax. The digitalisation of the tax should go beyond property registration but should cover all other aspects of digital taxation, ranging from assessment to payment of taxes.
Estimating the Property Taxation in WAEMU Countries: an Analysis
Authors: Fatoumbi Djibril Adékola , Alinsato Alastiar Sena
Published: May 2022

The question of efficient domestic tax revenue mobilisation in developing countries has continued to receive particular attention in recent years. This article evaluates the potential of property tax revenues in Western African Economic and Monetary Union (WAEMU) countries. To this end, three methods were employed using data from the Government Financial Statistics (GFS) of the International Monetary Fund (IMF) and the World Bank’s World Development Indicators (WDI). The Hodrick-Prescott filter method (1980) further allowed for a chronological estimation of the potential of property taxes while the optimisation model of Scully (1995) facilitated a punctual estimation of the potential informs concerning the significance of the parameters. Finally, the quadratic model of Laffer (1981) completed the results of Scully’s model. Overall, the results demonstrate the existence of sub-optimality in the collection of property taxes in WAEMU countries.

The objective of this study is to identify the determinants of property tax revenues in Togo. The data relate to the regions and prefectures and were collected from the services of the Togolese Revenue Authority (OTR) and from the Ministry of Justice over a period of five years (2016 to 2020). The results of the descriptive analysis show that the maritime region especially the capital Lomé alone generates more than 98 per cent of property tax revenues. The linear regression revealed that digitisation and awareness efforts inf luence positively the level of revenue collection. However, land disputes are an obstacle to the success of reforms that can optimise the mobilisation of property tax revenues.
Property Taxation and Efficiency Scores of Metropolitan Municipalities in South Africa
Authors: Jansen Ada , Mackenzie Onesmo Kaiya , Steyn Wynnona
Published: May 2022

Property taxation is a primary source of income for urban municipalities (metros), particularly in South Africa. Property tax collection amongst metros varies, which begs the question of whether differences in tax efficiency scores can be explained by institutional factors, or whether economic factors such as the size of the tax base or the ability to raise other revenues play a role. This article estimates property tax efficiency scores for eight South African metros and considers factors that affect these scores. We use municipal data and apply the data envelopment analysis method to estimate the efficiency scores for property taxation. This is followed by a Tobit regression to evaluate the determinants of these scores. The results show that although metros achieve relatively high efficiency scores, property tax collections can be improved. In addition, economic indicators explain variations in efficiency scores, but financial management remains key to delivering municipal infrastructure.
An Analysis of the Effects of Taxation on Income Inequalities in WAEMU
Authors: Tchila Pouwemdéou , Okey Mawussé Komlangan Nézan
Published: May 2022

This article analyses the potential effect that tax instruments have on income inequalities in sub-Saharan Africa particularly in the West African Economic and Monetary Union (WAEMU). Tax instruments are represented by various types of levies and taxes whereas income inequalities are estimated by the Gini index. Using the generalised method of moments over the period from 1990 to 2017, the results demonstrate that value-added tax, excise duties, and port charges have no effect on income inequalities whereas personal income tax and corporate income tax improve income distribution in the WAEMU. However, the globalisation of economies reverses the effect of corporate income tax. Moreover, tax progressivity reduces inequalities while the tax structure has no significant effect on income inequalities. To this end, the study recommends using direct and progressive tax instruments for the fight against inequalities. Similarly, the fight against aggressive tax optimisation must take a central stage in tax policies within an economy that is increasingly open to multinational companies.
