Authors: Santana Elivaldo Ribeiro de , Silva Ricardo Freitas da , Duarte Júlio Cesar Messias , Amaral Vera Lúcia de Sousa 
Published: November 2024

Objective: The objective of this work was to verify the correlation of the amount of transfers of ICMS-e with the expenses in the environmental management and sanitation functions of the municipalities with a Cerrado area greater than 50%.

Theoretical Framework: The creation of the ecological ICMS as financial compensation for municipalities that have a majority of their territory occupied by environmental conservation areas.

Method: The sample used is composed of 47 municipalities in the state of Mato Grosso do Sul. The transfer data of the ICMS-e were obtained through contact via institutional email with those responsible for the Management of Conservation Units (GUC) of the Environment Institute of Mato Grosso do Sul (IMASUL). Municipal expenditure data for the environmental management and sanitation functions were obtained from the website of the National Treasury Secretariat (STN) through the Finances of Brazil (FINBRA) application. The time frame of the data was from 2002 to 2012. Pearson's correlation analysis was applied at a significance level of 5% (p <0.05).

Results and Discussion: The results show that the relationship between the variables: annual total of transfers of ICMS-e (TAR_ICMS-e) and the annual total of expenditures in the environmental management function (TA_GestAmb) is positive and statistically significant (r = 0.872 and p = 0.000).

Research Implications: Given the above, it appears that the strength of the correlation coefficient is strong. Pearson's r coefficient also provides the degree of joint variation of these variables and, therefore, it is estimated that 76% of the investment in TA_GestAmb is a reflection of the transfer received from TAR_ICMS-e.

Originality/Value: Regarding the variable: total annual expenditure on the sanitation function (TA_San), the result shows a positive and not statistically significant correlation (r = 0.093 and p = 0.785), however, the effect is practically null.

Comment la morphologie de l’émission principale aurorale UV de Jupiter réagit-elle aux conditions changeantes dans la magnétosphère ?
Authors: Head Linus A. 
Published: November 2024

The ultraviolet aurorae of Jupiter, the brightest in the Solar System, are known to be of variable morphology. It is not entirely understood how this morphology varies with conditions present in Jupiter’s extensive magnetosphere, such as its state of compression. This work presents the first use of automatic detection techniques to analyse the morphology of Jupiter’s UV main auroral emission and link it with the state of the magnetosphere. A new reference oval for the average shape of the main emission is produced for the northern and southern hemisphere, based on images taken by Juno-UVS during its first 54 perijoves. A strong correlation is observed between the expansion/contraction of the main emission compared to these reference ovals in the northern and southern hemispheres, as well as between the main-emission expansion/contraction in the day and night hemispheres of the aurora, which indicates that the processes that work to vary the size of the main emission do so in a global way within the magnetosphere. The equatorward expansion also shows excellent correlation between with the equatorward latitudinal shift of the discrete aurora emission linked to Ganymede and the strength of the current in the magnetospheric current sheet, indicating that it is largely the stretching of the magnetic field of Jupiter that gives rise to the variable size of the main emission. Finally, compression of the magnetosphere is linked to a global main-emission contraction, one that occurs concurrently in both the north, south, day-side, and night-side hemispheres of the aurora, albeit to different extents. In all, these results indicate that the expansion or contraction of the UV main emission can be linked to a number of changes in the state of Jupiter’s magnetosphere and magnetic field.

Актуальность исследования обусловлена необходимостью решения задачи обучения моделей многоклассовых классификаторов, используемых в структуре системы федеративного машинного обучения, оперирующей обучающей выборкой данных, которая содержит как общедоступные данные, так и конфиденциальные данные, формирующие скрытые классы. Подобная проблема возникает в условиях обучения классификатора с использованием выборки данных, часть из которых состоит из персональной информации или данных различной степени конфиденциальности. В связи с этим данная статья направлена на исследование особенностей модели гауссовой смеси распределений как способа представления скрытых классов, представляющих конфиденциальные данные, а также обоснование выбора алгоритмического метода нахождения оценок максимального правдоподобия ее параметров. Ведущим методом решения проблемы идентификации параметров скрытых классов является обоснованно выбранная двухэтапная итерационная процедура «ожидание-максимизация» (EM-алгоритм), обеспечивающая усиление связи между пропущенными (конфиденциальными) данными и неизвестными параметрами модели данных, представленной гауссовой смесью распределений. В статье представлена схема разработанного алгоритма многоклассового классификатора системы федеративного машинного обучения, представленная параллельно выполняющимися циклами формирования локальных моделей обучения и их последующего ансамблирования в глобальную модель обучения.
The relevance of research is due the need to solve the problem of training multi-class classifier models used in federated machine learning system structure operating with a training data set that contains both publicly available data and confidential data that forming hidden classes. A similar problem arises in the context of training a classifier using a training data set, some of which consists of personal information or data of varying degrees of confidentiality. In this regard, this article is aimed at researching the features of the Gaussian mixture model of distributions as a way of representing hidden classes representing confidential data, as well as justifying the choice of an algorithmic method for finding maximum likelihood estimates of its parameters. The main method for solving the problem of identifying the parameters of hidden classes is a reasonably chosen two-stage iterative expectation-maximization procedure (EM-algorithm), which ensures strengthening the relationship between missing (confidential) data and unknown parameters of the data model represented by a Gaussian mixture of distributions. The article presents a diagram of the developed algorithm of a multi-class classifier for federated machine learning system, represented by parallel cycles of forming local learning models and their ensemble into a global learning model.

Niepełnosprawność i praca. Dyskursywne konstrukcje wykluczeń i akty niezgody
Authors: Woynarowska Agnieszka 
Published: November 2024

W niniejszym artykule autorka szkicuje problematykę wykluczeń osób z niepełnosprawnościami z obszaru zatrudnienia oraz objaśnia przyczyny trudnej do przezwyciężenia dyskryminacji na otwartym rynku pracy, która dotyka tę społeczną grupę. Omawiana problematyka ukazana jest w nawiązaniu to teorii studiów o niepełnosprawności oraz społeczno-kulturowego modelu niepełnosprawności postrzegającego niepełnosprawność jako wytwór dominującego dyskursu. Prezentując problem marginalizacji osób z niepełnosprawnościami na rynku pracy, autorka sięga do korzeni wszelkich ekskluzji powstałych w dobie wczesnego kapitalizmu przemysłowego, który stworzył, a następnie wykluczył „nieproduktywne ciało” z obszaru zatrudnienia, następnie nawiązując do koncepcji ekonomicznego modelu niepełnosprawności omawia obszary ekonomicznej opresji, utrwalane dyskursywnie praktyki wykluczające oraz ukazuje działania próbujące przeciwstawić się narzuconemu porządkowi poprzez żmudne „żłobienie nowych linii ujścia” walczące z despotą kapitalistycznego rynku pracy.

Published: November 2024

The purpose of this study is to increase the efficiency of underground block metal leaching by increasing the metal content in the pregnant solution using the cavitation effect. To achieve this goal, it is proposed to process (cavitate) the leaching solution on the injector. The following research methods were used in this study: analysis of the current state of scientific and technical problems and research, laboratory work to establish the effect of the treated (cavitated) solution on the metal content in the pregnant solution, collection and processing of statistical data from laboratory work, analysis of research results, and preparation of conclusions. According to the results of laboratory research, leaching with a treated solution on an injector leads to an increase in the content of a useful component in the pregnant solution. The maximum increase in the metal content in the pregnant solution was achieved by processing the leaching solution for 5 min. The effectiveness of the solution over time after treatment was maintained for a long time (up to one month). Changes in the solution pressure did not affect the effectiveness of the treated leaching solution. The scientific novelty of this work consists of determining the dependence of the content of the useful component in the pregnant solution on the time of processing the leaching solution on the injector and the leaching time, which determines the optimal time for processing the solution on the injector to obtain the maximum metal content in the pregnant solution. The dependence of the content of the useful component in the solution on the pressure during leaching with untreated and treated solutions on the injector was obtained.

Effect of Porous Rectangular Type Baffle Block Angle on Hydraulic Jump Downstream of Spillway
Authors: Djunur Lutfi Hair , Pallu Muhammad S. , Karamma Riswal , Bakri Bambang 
Published: November 2024

The elevation of the water surface upstream of the spillway structure increases significantly due to damming, leading to a rapid, supercritical flow downstream. This flow transitions from supercritical to subcritical, resulting in hydraulic jumps (Lj). The placement of a porous rectangular baffle block in the chute acts as an energy dissipator within the channel. This study aimed to investigate the effect of the angle of the porous rectangular baffle block on energy dissipation and hydraulic jumps downstream of the spillway structure. The experiment utilized a two-dimensional (2D) approach to evaluate energy dissipation and hydraulic jumps under various placements of the porous rectangular baffle block in the chute. The results indicated that the water level above the weir (hd) increased, along with turbulence downstream, while energy loss decreased. However, the efficiency of energy dissipation improved as variations in the water level above the weir decreased. A baffle block with an angle (α) of 60° was found to be the most effective in dissipating flow energy and shortening hydraulic jumps. Additionally, an empirical equation was developed for the hydraulic jump length as a function of the downstream Froude number (Fr): Lj=yt (k α hd(Fr-1)^4). The porous rectangular baffle block proved advantageous as it gradually dissipates flow velocity through its pore openings, preventing flow momentum reversal.
