Factores explicativos de la eficiencia educativa en Uruguay: evidencia a partir de PISA 2012.
Authors: Sicilia Gabriela
Published: March 2024

Resumen. El enorme esfuerzo presupuestario observado en Uruguay en la última década no ha sido acompañado de mejoras en los resultados académicos, lo cual evidencia la posible presencia de ineficiencias en el sistema educativo. En este sentido, el objetivo de este artículo es identificar los factores determinantes de la eficiencia educativa en los centros públicos de educación secundaria. En base a la información de PISA 2012, las estimaciones revelan que sería posible mejorar los resultados académicos en un 7,4% en promedio dado los recursos actuales. Para ello, las políticas educativas deberían focalizarse en revisar las políticas de repetición vigentes, las prácticas de instrucción docente y la gestión de los docentes en los centros, así como trabajar sobre el grado de estrés de los estudiantes asociado al trabajo con las matemáticas.
Autonomía Universitaria en el Siglo XXI: nuevas formas de legitimidad ante las transformaciones del Estado y la Sociedad. University Autonomy in the Twenty-first Century: New Forms of Legitimation Under the Changes of State and Society.
Authors: Bernasconi Andrés
Published: March 2024

Resumen. En este artículo voy a señalar qué es y para qué sirve la autonomía universitaria, además de postular y argumentar la relación estrecha que existe entre autonomía y legitimidad del gobierno universitario. En primer lugar, voy a reiterar la noción elemental de que la autonomía existe principalmente para proteger la libertad académica y por lo tanto merece protección porque es esencial para que la universidad entregue a la sociedad el servicio que le es propio: descubrir y comunicar el conocimiento de las ciencias, las artes y las humanidades. En segundo lugar, voy a afirmar que, como todo gobierno, el de la universidad requiere de legitimidad para sostenerse y esa legitimidad no puede desatender la aptitud del gobierno universitario para conducir a la universidad hacia el cumplimiento de su misión. Autonomía y forma de gobierno están al servicio de un bien mayor, a saber, el cumplimiento por la universidad de la función social que la distingue como institución. Abstract. In this article I will define what university autonomy is, and will discuss the close relationship between university autonomy and legitimacy of university government. First, I will go over the elementary notion that autonomy exists mainly to protect academic freedom and therefore deserves protection since it is essential for the university delivering to society its own service: discover and convey knowledge on sciences, arts and humanities. Secondly, I will say that, as any government, the university requires of such a legitimacy which should not disregard the university government ability to lead it towards the fulfillment of its mission. Both autonomy and university government exist for the fulfillment of a greater aim, namely, compliance by the university of the social function that distinguishes it as an institution.
Enseñanza Superior en Brasil y las políticas de inclusión social. Higher Education in Brazil and Social Inclusion Policies.
Authors: Baeta Neves Clarissa Eckert
Published: March 2024

Resumen. El artículo analiza las políticas de inclusión social para estudiantes de bajos ingresos y/o que pertenecen a grupos raciales minoritarios: la política de cuotas (sector público) y el Programa Universidade para Todos/ProUni (sector privado). Se estudia la evaluación que realizan los estudiantes sobre su trayectoria educativa hasta la llegada a la Enseñanza Superior y lo que significa “estar en una universidad” en sus vidas. Los estudiantes entrevistados tienen una percepción positiva sobre las políticas. La oportunidad de ingresar a una universidad produce una diferenciación en sus vidas y favorece las expectativas de cambio de posición en la estructura social, adquisición de nuevos capitales escolares y simbólicos rompiendo con la noción de transmisión mecánica del capital cultural heredado. Abstract. This article examines social inclusion policies for low-income students and/or students who belong to minority racial groups: a policy of quotas (public sector) and the Programa Universidade para Todos/ProUni (University for All Program/ProUni) (private sector); and the appraisal beneficiary students make about their trajectory until entering Higher Education, as well as what means in their lives “to be in the university”. Interviewed students have a positive perception of policies. The opportunity of entering university makes the difference in their lives bringing the expectation of changes in social position, acquiring new school and symbolic capitals, doing away with the notion of mechanical transmission of the inherited cultural capital.

La violencia y la enseñanza de la historia nacional en el escenario institucional colombiano (1948-2006). Violence and National History Teaching (1948-2006): an Institutional Colombian Perspective.
Authors: González Moreno María Isabel Cristina
Published: March 2024

A lo largo de la segunda mitad del siglo xx, es posible rastrear en Colombia múltiples reformas estatales a la Educación Media en materia de planes de estudio y currículos. Detrás de cada una sale a relucir una racionalidad que excede las lógicas del campo educativo y que, más bien, se entrelaza con el proyecto político gubernamental de turno y sus requerimientos ideoló- gicos, o con coyunturas sociopolíticas determinadas. Esta incidencia del mundo político en el educativo se revela de manera particular en las asignaturas escolares que abordan la historia nacional. Dentro de esta perspectiva, se muestra cómo, tras las transformaciones institucionales registradas, se impulsaron diferentes memorias y visiones de ciudadanía, democracia, nación y conflicto que ponen en evidencia líneas de subordinación del proyecto educativo al amplio universo de las dinámicas políticas.Abstract:It is possible to track multiple State reforms to Secondary Education in terms of curricula and syllabus throughout the second half of the Twentieth century in Colombia. Underlying each reform, one can identify a rationality that surpasses the logic of Education, and is rather intertwined with the political project and ideological requirements of the government in office, or with certain socio-political junctures. The impact of the political world on education is particularly noticeable in school subjects that address national history. Within this perspective it is shown how, after institutional changes have occurred, different memories and visions about citizenship, democracy, conflict and nation are being promoted. This highlights different ways of subordination of the educational project to a wide universe of political dynamics

Published: March 2024

Resumen. Aquí se presentan los resultados de una investigación sobre el impacto del sistema PCI en tres centros educativos a través del estudio de cuatro dimensiones organizacionales que afectan los aprendizajes: comuni-cación, clima, enseñanza, y aprendizaje y satisfacción de las personas. Además de encontrarse evidencia para afirmar que los docentes consideran que el sistema de calidad PCI ha contribuido a mejorar a su centro educativo, los análisis estadísticos no revelan que haya diferencias estadísticamente significativas entre ellos asociadas a su tamaño y/o población que atienden, por lo que se ha podido observar versatilidad en el sistema estudiado.
Utilização de periódicos como referencial teórico nas dissertãçoes e teses sobre a formaço continuada de professores (2010-2014).
Authors: Schiavon Sandra Helena , Fagundes Da Silva Elza , Do Rocio Artigas Joanita
Published: March 2024

RESUMO. A finalidade do presente artigo é avaliar a utilização de periódicos nas pesquisas sobre formação continuada de professores em dissertações e teses on-line disponíveis no Portal CAPES no período de 2010-2014. Trata-se de pesquisa exploratória, com abordagem quantitativa. O material de análise e referência foi constituído pelas dissertações e teses dos Programas de Mestrado e Doutorado em Educação no Brasil, no período de 2010 a 2014, disponíveis no portal de domínio público – Biblioteca Digital, da CAPES e selecionadas pelos descritores “Formação de Professor” e “Formação continuada do professor”. Os resultados mostram que apenas 12,1% das pesquisas sobre formação do professor utilizam os periódicos como referencial teórico. Conclui-se que a utilização de periódicos no campo da pesquisa acadêmica ainda é incipiente e muitos pesquisadores ainda utilizam periódicos sem nível de impacto ou não indexados. Uma das limitações do estudo foi a utilização de apenas uma base de dados para a coleta das dissertações e teses que continham os descritores selecionados. É de extrema importância divulgar, entre os pesquisadores, que a utilização de periódicos como referencial bibliográfico pode fornecer estudos mais recentes dos temas a serem investigados.

Published: March 2024

Integrated crop-livestock-forest (ICLF) systems involve intercropping of various crops to achieve beneficial and synergistic outcomes, enhancing both economic viability and environmental sustainability. Considering the complexity of integrated agrosystems and the economic importance of soybean production in Brazil, we aimed to investigate the effects of two ICLF systems on the physical characteristics and quality of soybeans produced. The treatments comprised plots (two ha) with either single-row (ICLFS) or triple-row (ICLFT), tree configurations intercropped with soybean (maize and forage grass), and control plots (one ha), whose crops were cultivated under full sunlight (CFS). Soybeans were harvested from plants located at 3, 6, 10 and 15 m from tree bands in the north and south faces of the ICLF systems and at random positions in the CFS plots. The moisture content, electrical conductivity of the exudate solution, hue angle and chroma index of grains harvested from ICLFS and ICLFT were similar to those of CFS-grown soybeans. However, the mass of 1000 grains and the bulk density values of ICLF-grown soybeans were significantly higher (P ≤ 0.05) than those of grains harvested from CFS plots. We conclude that the quality of soybean seeds was not negatively affected by the conditions prevailing in the ICLF systems. Moreover, it appears that the forest component contributed positively to the ecosystem by providing a favorable microclimate for the development of soybean grains.
Sejas “plīvurs” kā musulmaņu sievietes identitātes rīks un politiskās teoloģijas sociālpolitiska barjera Eiropā
Authors:   Latvijas Universitāte, Dāvidsone Inese
Published: March 2024

Sejas aizklāšana ir reliģiska barjera, kas sievieti jau gadsimtiem sargājusi no svešām acīm, ļaujot saglabāt tikumību un cieņu sabiedriskajā telpā. Līdz ar islāma izplatību pasaulē un citu kultūru un valstu likumu ietekmi vēsturiskais aspekts kļuvis apstrīdams, dodot pamatu bažām, šaubām, diskusijām, tiesas prāvām un reliģijas normu pārvērtēšanai. Rakstā aplūkots musulmaņu sievietes sejas ietērps no teoloģiskā un juridiskā viedokļa, islāma ticības pamatteksti, sieviešu tiesības un pienākumi pret valsti Eiropas valstu likumdošanā, kā arī tas, kāpēc sejas elements ir kļuvis par aktuālu tēmu musulmaņu kultūrā Eiropā. Tēze – teoloģiski politiskie ierobežojumi rada slēptus draudus sociālajai videi un vājina sievietes identitātes vietu islāma ticībā. Rakstā blakus nostatīti islāma principi attiecībā uz sievietes lomu, izskatu, uzvedību un reliģijas gaidām un Rietumu sabiedrības izpratnes pretstats, kas politiski, sociāli un likumiski sievieti nereti ierobežo vēl vairāk nekā sejas aizsegums nikāba apģērbā. ​​​​​​​Darbā izmantota vēsturiskā metode, veicot avotu analīzi, un sintēzes metode, meklējot labākā skaidrojuma definīciju un lietojumu. Tāpat, aplūkojot sieviešu identitāti islāmā, izmantota hermeneitikas tekstu interpretācijas metode.
Dzelzs ferocianīda modificēšana cilvēku un vides aizsardzībai no radioaktīvā cēzija iedarbības
Authors:   Latvijas Universitāte, Eismonts Uģis
Published: March 2024

Pēc Krievijas Federācijas agresijas Ukrainā un tai sekojošajiem notikumiem pasaulē ar katru dienu palielinās iespēja, ka šajā konfliktā varētu tikt izmantoti arī kodolieroči, kas potenciāli apdraud visu valstu iedzīvotājus, īpaši tos, kas atrodas tuvāk Ukrainas teritorijai, tajā skaitā arī Latviju. Dzelzs ferocianīds ir perspektīvs, maztoksisks metālorganisks savienojums. Pirmo reizi tas tika sintezēts 1706. gadā, un pēdējos gadu desmitos zinātnisko publikāciju skaits par šo savienojumu tikai aug, jo tas ir izmantojams gan medicīnā, gan arī, piemēram, bateriju ražošanā. Lai iegūtu atkārtojamu sintēzes reakcijas iznākumu, ir jābūt specifiskiem apstākļiem – gan pH, gan reakcijas ātruma, gan temperatūras kontrolei. Darbā analizēta dzelzs ferocianīda spēja nepieļaut cēzija radioaktīvo savienojumu nokļūšanu cilvēka organismā un nepieciešamības gadījumā tā spēja iespējami ātri un efektīvi izvadīt to no organisma. Aprakstīta arī specifiska dzelzs ferocianīda sintēze, par pamatu izmantojot vienīgā Latvijas teritorijā dzimušā un strādājušā ķīmiķa – Nobela prēmijas laureāta Vilhelma Ostvalda – ģeniālo novērojumu par mehanoķīmiskām reakcijām. Šāda sintēzes shēma dotu iespēju Latvijai nodrošināt saviem iedzīvotājiem un varonīgajiem aizstāvjiem maksimāli ātri un efektīvi sagatavotus individuālās aizsardzības līdzekļus, lai iespēju robežās pasargātu savu organismu un vidi no radioaktīvā piesārņojuma un šī piesārņojuma izraisītajām sekām.

Authors: Saraswathi K. , Nandhagopal Koushik Kumar , Nandhini S , Cyrus Bernard Ebenezer , Kirupa K. , Aishwarya B. , Pavithra S.
Published: March 2024

The temporomandibular joint is a synovial joint made up of articulating surface of the temporal bone and the head of the mandible.Patients suffering from temporomandibular joint pain syndrome will frequently have pain in the region, limitation in opening, asymmetrical jawmovements, and restricted jaw movements. The etiology is associated with several factors, including malocclusion, trauma, emotional stress,and para-functional habits, which cause excruciating pain and inflammation of the surrounding muscle, posterior fibers, and synovial fluid. Thisstudy evaluated and compared the effectiveness of low-level laser therapy (LLLT) and ultrasound therapy (UST) in managing temporomandibularjoint pain syndrome. This experimental study of pre and post-comparative types involves 30 subjects with temporomandibular joint painsyndrome who were selected from the outpatient department. This study included 30 subjects divided into two groups of each 15 by simplerandom sampling method.15 sessions each alternate day of low-level laser therapy (GROUP A) and ultrasound therapy (GROUP B) wereadministered to the affected side. Both groups received stretching exercises as a common intervention. Group A received low-level lasertherapy along with stretching exercises for 7 sessions /week/10 min. Group B received ultrasound therapy and stretching exercises for 7sessions /one weeks/10 min. On comparing the mean values of Group A & Group B on the Visual Analogue Scale Score in terms of painintensity, it shows a significant decrease in the post-test mean values in both groups, but (Group A - Low-level Laser Therapy) shows 2.33,which has the lower mean value is more effective than (Group B - Ultrasound Therapy) 3.53 at P ≤ 0.001. Hence the null Hypothesis isrejected. On comparing the pre-test and Post-test between Group A & Group B on VAS Score, Group A shows a highly significant difference inmean values at P ≤ 0. 001. Thus, we conclude that low-level laser therapy is more effective than ultrasound therapy in the management oftemporomandibular joint pain syndrome.
The Impact of E-Business Technologies and Social Media Marketing on Indonesian SMEs Sustainability
Authors: Prabowo Hartiwi , Sriwidadi Teguh
Published: March 2024

Objectives: As a result of the COVID-19 pandemic, many MSMEs in Indonesia have experienced losses and some have even gone bankrupt. To try to keep their business running, MSMEs must carry out digital transformation, including by selling their merchandise via the internet, using social media such as Instagram and Facebook, as well as online markets including Tokopedia, Shopee, Bukalapak, Blibli, and Lazada. By using the internet for business, it is necessary to know the role of e-business technology and social media marketing. Therefore, this research examines how perceived usefulness, perceived ease of use, and digital transformation influence the sustainability of SMEs through e-business technology and social media marketing.Methodology: This research uses quantitative methods with a type of causal research. The population in this study were members of the CUP Bestari UKM community, numbering around 600 SMEs. To determine the sample size, the convenience sampling method was used, the sampling process was from the population closest and easiest to reach for researchers, taken from members of the CUP Bestari SMEs participating in the November 2021 bazaar at the Periuk District Hall, Tangerang City, totaling 108 samples. Primary data collection was carried out using a questionnaire by sending a Google Forms link to members of the UKM CUP Bestari community via WhatsApp. Then the data was analyzed using partial square rent structural equation modeling techniques. Finding:  As a result, perceived usefulness and perceived ease of use have a significant influence on e-business technology. Perceived ease of use significantly affects social media marketing, perceived usefulness does not affect social media marketing. In addition, e-business technology significantly influences SMEs' sustainability, and e-business technology also influences SMEs' sustainability. Perceived usefulness and perceived ease of use influence SME sustainability both through e-business technology and through social media marketing. Meanwhile, digital transformation does not influence social media marketing both direct and indirect through social media marketing as a mediator.Conclusion: SME sustainability is influenced by factors of perceived usefulness, and perceived ease of use with e-business technology, and social media marketing as mediating variables. Another factor, namely digital transformation does not influence social media marketing both directly and indirectly through social media marketing as a mediator. In future research, it is recommended to use digital transformation as a variable that moderates the achievement of SME sustainability.

Authors: Zahri Cut , Sopang Fandi Iskandar , Irwandi Bambang
Published: March 2024

Objectives: In this study, capital structure is used as an intermediary variable to examine how liquidity, profitability, and company size affect firm value. This study is anticipated to serve as a resource for future research as well as help businesses and investors make a variety of decisions.Methodology: This study uses secondary data and is quantitative. These facts were gathered via documentation methods. All of the firms in the food and beverage sectors that are listed on the IDX 2020–2021 make up the study's population. Purposive sampling was used to collect samples from 158 observations.Finding: According to the study's findings, liquidity, profitability, firm size, and capital structure had an impact on share value while only partially having an impact on capital structure. The outcomes of the path analysis demonstrate that while profitability has an impact on share value mediated by capital structure, liquidity, and company size do not have an impact on share value.Conclusion: Future researchers are urged by the findings of this study to include other variables, including external variables like inflation, interest rates, and taxes which may have an impact on business value
The Role of Customer Value as Intervening in Repurchase Decisions: The Case of Skincare Indonesia
Authors: Panjaitan Feliks Anggia Binsar Kristian , Panjaitan Hotman
Published: March 2024

Objectives: Companies can more easily communicate product information by using digital marketing. Indonesian manufacturers of skincare products use digital marketing to advertise and promote their goods to a larger target audience. The objective of this study is to assess the potential mediating role of customer value in the relationship between digital marketing, product quality, brand perception, and the decision-making process of repurchasing products. Methodology: A quantitative research approach using purposive sampling of 210 research respondents from the population of Indonesian skin care product consumers based in Surabaya. Analysis was carried out using structural equation models, with Warp PLS 5.0 software.Finding: The results demonstrate that customer value does not mediate the relationship between digital marketing and repurchase decisions. The influence of brand perception and product quality on decisions to repurchase goods is mediated by customer value. Research findings also indicate that in comparison to digital marketing, factors such as product quality and brand image have a favorable impact on customer value. Conclusion: It is important to assess and improve how skin care products are marketed and promoted online. Brand perception, product quality, and customer value can increase customer repeat purchases. These findings have implications for the skin care business and highlight the need to prioritize factors that contribute to customer value to drive sales and increase customer repurchase decisions.
Organizacja oparta na wiedzy a CSR
Authors: Wołoszyn Jan , Ratajczak Marcin

W literaturze ekonomicznej, polityce uprawianej przez ludzi o neoliberalnych zapatrywaniach oraz praktyce biznesowej panowało do niedawna powszechne przekonanie, że przedsiębiorstwa istnieją po to, aby przynosić zysk dla ich właścicieli. Powoływano się przy tym na poglądy M. Friedmana, laureata Nagrody Nobla w dziedzinie ekonomii, który jest zdania, że w gospodarce rynkowej przedsiębiorstwa swoje zasoby i całą energię powinny wykorzystać na pomnażanie zysków, na podstawie określonych norm postępowania, bez naciągania i oszustw. Takie podejście do prowadzenia biznesu wyklucza prowadzenie przez przedsiębiorstwa różnych form działalności na rzecz społeczeństwa oraz ich współodpowiedzialność za ekologię. Podobne stanowisko można spotkać również obecnie, choć nie jest już ono tak powszechne. Coraz więcej bowiem menedżerów troski o wartość rynkową przedsiębiorstwa, o jego sukces nie przeciwstawia społecznej wrażliwości i społecznej odpowiedzialności. Chodzi tu zarówno o odpowiedzialność za sytuację materialną, bezpieczeństwo i rozwój własnych pracowników, jak też o poszanowanie praw społeczności lokalnej, o przestrzeganie zasad demokracji, o fair play w grze rynkowej, o uczestnictwo w rozwoju społeczeństwa obywatelskiego oraz o dbałość o środowisko naturalne. Uważają bowiem, iż wdrożenie zasad społecznej odpowiedzialności (Corporate Social Responsibility) nie obniża jego wartości, a nawet może ją pomnożyć. Można więc postawić pytanie, czy między organizacją, która promuje innowacyjność, kreatywność i otwartość na wiedzę, a organizacją, która wdraża zasady odpowiedzialnego społecznie biznesu istnieje zależność? Z wielu badań, a także obserwacji funkcjonowania przedsiębiorstw wynika, że taka prosta zależność nie istnieje. Są bowiem przedsiębiorstwa, które można zaliczyć do organizacji uczących się, a które nie przestrzegają niektórych zasad odpowiedzialności społecznej, między innymi nie przejawiają należytej troski o środowisko naturalne, czy też o własnych pracowników, zatrudniając np. dzieci do niektórych prac. Z kolei badania wskazują, że przedsiębiorstwa nastawione na ludzi, otwarte na nowości, niebojące się zmiany, promujące wspólny wysiłek i zaangażowanie wszystkich pracowników tworzą klimat sprzyjający poznawaniu i wdrażaniu zasad społecznej odpowiedzialności. Pracownicy, gdy ceni się ich potencjał intelektualny, gdy tworzy się im warunki do pozyskiwania, kreowania i dzielenia się wiedzą, są bowiem bardziej świadomi potrzeby dbania o środowisko naturalne, a także wrażliwi na kulturę i potrzeby społeczności lokalnej, partnerów biznesowych, klientów i konsumentów. Celem niniejszego artykułu jest ukazanie cech organizacji uczącej się oraz przybliżenie idei CSR, zwłaszcza z tych obszarów, które mają powiązania z cechami organizacji opartej na wiedzy.
Kryteria estetyczne narzucane przez sieci handlowe a potencjalne utracone korzyści w produkcji podstawowej marchwi. Studium przypadku
Authors: Bieniek-Majka Maryla
Published: March 2024

Celem niniejszego opracowania jest wskazanie wysokości potencjalnych, utraconych przychodów dla badanych producentów marchwi wynikających ze strat w produkcji podstawowej. Nadmierne straty spowodowane są koniecznością stosowania kryteriów estetycznych narzuconych przez sieci handlowe. Materiałem źródłowym była literatura przedmiotu, dokumentacja księgowa za lata 2019-2022 oraz informacje pozyskane podczas wywiadów eksperckich z producentami marchwi, które zostały przeprowadzone w styczniu 2023 roku. Badaniem objęto dobranych celowo 7 producentów, których zagregowana wielkość zbiorów marchwi stanowiła w 2021 roku około 15% wielkości zbiorów w województwie kujawsko-pomorskim i około 2,8% w kraju. Rozmiary strat przedstawiono na podstawie wskaźnika bilansu mas. Stwierdzono, że tylko 43,86% zebranego surowca jest sprzedawana jako pełnowartościowy produkt (zaakceptowany przez sieci handlowe). Pozostała część jest dostarczana jako pokarm dla zwierząt, surowiec do przetwórstwa bądź paliwo do biogazowni. Wartość potencjalnych, utraconych korzyści oszacowano na podstawie różnicy uzyskanego przychodu ze sprzedaży produktów odrzuconych, a wartością potencjalnego przychodu uzyskanego przy założeniu, że producenci mogliby sprzedać 50% masy odrzuconej marchwi po średniej cenie rynkowej produktu spełniającego „normy” z upustem cenowym w wysokości 30%, 50% lub 70%. Z przeprowadzonej analizy wynika, że średnie przychody producenta (przy uwzględnieniu przyjętych założeń) mogłyby być wyższe od 30% do 173%, co dałoby wyższy przychód od 0,34 mln zł do 1,92 mln zł rocznie.
Regular integral transformations on time scales and generalized statistical convergence
Authors: Turan Yalçın , Duman Oktay
Published: March 2024

In this work, using regular integral transformations on time scales, we
generalize the concept of statistical convergence. This enables us not only
to unify discrete and continuous cases known in the literature but also to
derive new convergence methods with choices of appropriate transformations
and time scales. This is a continuation of our earlier work and includes
many new methods. We obtain sufficient conditions for regularity of kernel
functions on time scales and also we prove a characterization theorem for
the generalized statistical convergence. At the end of the paper we display
some applications and special cases of our results.
Approximation of functions belonging to Hölder’s class and solution of Lane-Emden differential equation using Gegenbauer wavelets
Authors: Lal Shyam , Yadav Harish
Published: March 2024

In this paper, a very new technique based on the Gegenbauer wavelet series is
introduced to solve the Lane-Emden differential equation. The Gegenbauer
wavelets are derived by dilation and translation of an orthogonal Gegenbauer
polynomial. The orthonormality of Gegenbauer wavelets is verified by the
orthogonality of classical Gegenbauer polynomials. The convergence analysis
of Gegenbauer wavelet series is studied in H?lder?s class. H?lder?s class
H?[0,1) and H?[0,1) of functions are considered, H?[0,1) class consides
with classical H?lder?s class H?[0, 1) if ?(t) = t?, 0 < ? ? 1. The
Gegenbauer wavelet approximations of solution functions of the Lane-Emden
differential equation in these classes are determined by partial sums of
their wavelet series. In briefly, four approximations E(1) 2k?1,0, E(1)
2k?1,M, E(2) 2k?1,0, E(2) 2k?1,M of solution functions of classes H?[0, 1),
H?[0, 1) by (2k?1, 0)th and (2k?1,M)th partial sums of their Gegenbauer
wavelet expansions have been estimated. The solution of the Lane-Emden
differential equation obtained by the Gegenbauer wavelets is compared to its
solution derived by using Legendre wavelets and Chebyshev wavelets. It is
observed that the solutions obtained by Gegenbauer wavelets are better than
those obtained by using Legendre wavelets and Chebyshev wavelets, and they
coincide almost exactly with their exact solutions. This is an
accomplishment of this research paper in wavelet analysis.
Some results on higher order symmetric operators
Authors: Shen Junli , Zuo Fei , Chen Alatancang
Published: March 2024

For some operator A ? B(H), positive integers m and k, an operator T ? B(H)
is called k-quasi-(A,m)-symmetric if T*k( mP j=0 (?1)j(m j )T*m?jATj)Tk =
0, which is a generalization of the m-symmetric operator. In this paper,
some basic structural properties of k-quasi-(A,m)-symmetric operators are
established with the help of operator matrix representation. We also show
that if T and Q are commuting operators, T is k-quasi-(A,m)-symmetric and Q
is n-nilpotent, then T + Q is (k + n ? 1)-quasi-(A,m + 2n ? 2)-symmetric. In
addition, we obtain that every power of k-quasi-(A,m)-symmetric is also
k-quasi-(A,m)-symmetric. Finally, some spectral properties of
k-quasi-(A,m)-symmetric are investigated.
On m-closure of ideals in a class of subrings of C(X)
Authors: Etebar Masoumeh , Parsinia Mehdi
Published: March 2024

A subalgebra A(X) of C(X) is said to be a ?-subalgebra if it is closed under
bounded inversion and the space of its maximal ideals equipped with the
hull-kernel topology is homeomorphic to ?X with a homeomorphism which leaves
X pointwise fixed. Kharbhih and Dutta in [Closure formula for ideals in
intermediate rings, Appl. Gen. Topol. 21 (2) (2020), 195-200] showed that
the closure of every ideal I of an intermediate ring with the m-topology,
briefly, the m-closure of I, equals the intersection of all maximal ideals
in A(X) containing I. In this paper, we extend this fact to the class of

Hematuria is a relatively common condition among school-aged children. Because international guidelines for asymptomatic hematuria in children are unavailable, developing practical guidelines for the diagnosis and management of asymptomatic hematuria based on scientific evidence while considering real-world practice settings, values, and patient and physician preferences is essential. The Korean Society of Pediatric Nephrology developed clinical guidelines to address key questions regarding the diagnosis and management of asymptomatic hematuria in children.

Authors: Pandey Ankita , Rai D. P.
Published: March 2024

This research  was conducted in the Department of Technology Transfer, Faculty of Agriculture, MGCGVV, Chitrakoot, Satna, Madhya Pradesh, India during 2022 to investigate the constraints faced by rural farm women while participating in decision-making processes related to animal husbandry activities. A sample of 340 farm women was surveyed in Dewas district of Madhya Pradesh, India in year 2019–20. Socioeconomics distribution reveals that the majority of respondents were in the medium age category (36 to 55 years), comprising 56.47% of the sample. The education status of participants varied, with a large proportion (43.23%) being illiterate. Among the educated individuals, primary education was the most common (36.17%), followed by middle education (12.94%). Regarding annual income, the majority fell into the medium category (56.76%), with low and high-income groups comprising 22.06% and 21.18% respectively. In terms of milch animals, the medium category (5–10 animals) was the most prevalent (45.88%). The study reveals that costly management, lack of technical knowledge, high cost of milch animals, social and cultural norms, and dominancy of other family members are significant barriers to women’s participation. The top three constraints identified by the women were costly management (97.35%), lack of technical know-how (96.76%), and high cost of milch animals (87.05%). These constraints highlight the need for providing technical and financial assistance to women engaged in animal husbandry activities. The findings underscore the importance of addressing these constraints through technical and financial assistance, capacity building programs, and improvements in veterinary services. By overcoming these constraints, women’s participation in decision-making processes can be enhanced, leading to improved agricultural practices and livelihoods in rural areas.

Development and project development in Indonesia is very important and is expected to have a good impact on the economy of this country. To achieve reliable development, it is necessary to manage human resources with the aim of increasing construction productivity. The factor influencing productivity is one of the benchmarks for the success of construction development implementation. This study aims to analyze the factors and occupations that have a relative effect on labor productivity in the Hurun Beach Resort Project. The AHP method is the research method used to carry out the analysis in this study. This is because decision-making criteria and alternatives become a reference to obtain achievements so that the percentage of the desired productivity factor can be known. Based on the results of the sub-criteria analysis, the relatively influential factor is the shop drawing with a weight of 0.19432, the second is the experience factor of 0.11948, and the third is the factor of adding working hours 0.10936. After analyzing the sub-criteria and then getting the final weight, the alternative superstructure work that is relatively influential is formwork work with a weight of 0.03413, the second is ironwork 0.03049, and the third is casting work 0, 0207.

Objectives: We aimed to determine the reasons for the emigration of health workers who left Turkey and the difficulties experienced before and after the migration.Methods: This is an exploratory qualitative study of open-text fields focusing on migrant health workers from Turkey. Answers given to five open-ended questions directed to the participants in our survey, with 513 participants between April and June 2022, were used. Data were analyzed following content analysis.Results: A total of 506 responses were analyzed. The mean age of the participants was 39.9 ± 8.8 years (54.2% men, 77.5% medical doctors). Almost all participants reported that the political atmosphere in Turkey forced them to migrate. Some participants were unable to do their jobs due to the increasing violence in the health system in recent years. Most participants saw migration as the only way out, as they did not feel free and safe. Comparatively, they were in a better economic situation in Turkey and had a higher standard of living.Conclusion: Migration creates a sense of security while at the same time accepting a lower standard of living. To organize the sustainable migration of professionals, it is beneficial to ask what framework conditions need to be created and to access the labor market in particular.
Effect of probenecid on astrocyte activation in vitro
Authors: Babkina II , Mazeeva VV , Morozova MP , Gorbacheva LR
Published: March 2024

Both acute brain injuries and neurodegenerative diseases are accompanied by neuroinflammation. The outcome of neuroinflammation and the prognosis of brain functional status depend on the balance of pro-inflammatory and anti-inflammatory factors. Many studies are aimed at finding possible therapeutic targets allowing to shift inflammatory response processes towards anti-inflammatory mechanisms. It has been shown that channels formed by pannexin proteins are expressed in all brain cells including astrocytes. However, their role in the processes of neuroinflammation is still unclear. Channels formed by pannexin 1 (Panx1) may be involved in proinflammatory activation of astrocytes induced by thrombin and/or lipopolysaccharide (LPS). The aim of this study was to assess thrombin- and LPS-induced activation of primary mouse cortical astrocytes under Panx1 blockade by probenecid. Functional profile of astrocytes, their proliferation and secretory activity changed both in case of thrombin application (50 nM and 100 nM) and in case of incubating cells with LPS. The observed increasing of nitric oxide (NO), β-hexosaminidase HEX and IL6 secretion stopped after the cells were treated with probenecid. Based on the obtained results, probenecid can be considered as a potential agent influencing the inflammatory process in brain tissue by stabilizing astrocytes through inactivation of Panx1 and reduction of astrogliosis.

Maintaining and enhancing employee loyalty and satisfaction has always been a top priority for management in every firm. This study aims to investigate the relationship between workplace spirituality, loyalty, and Generation Y employees at private organisations in Indonesia. A quantitative approach with descriptive and verification analysis techniques is used to see the picture and examine the relationship between variables. Data and information were obtained from a sample of 132 people, through the process of distributing questionnaires and surveys. Data analysis using statistical software calculation tools. The results showed that each variable has a fairly high criterion. Employee loyalty is significantly influenced by workplace spirituality and job satisfaction. The results demonstrate that workers who uphold spiritual principles at work are more likely to desire to remain with the company. The theoretical contribution of this study is that Generation Y employee loyalty can be increased by increasing job satisfaction and workplace spirituality. The growth of spiritual values needs to be supported by creating a spiritual work environment, providing fair remuneration is expected to foster loyal attitudes and behavior of employees. Research is limited to Y-generation and to objects in private tertiary institutions in Garut Regency where there is a possibility of cultural similarities, therefore further research is suggested with a wider scope.
El insuficiente apoyo a la vivienda protegida en la España rural y el reto demográfico
Authors: Moreno Mozo Fernando
Published: March 2024

Frente a una España muy poblada, existen regiones con escasa población, y es precisamente en éstas donde proliferan las zonas rurales, configurando un desierto demográfico con escasos núcleos urbanos. Desde hace décadas este éxodo del pueblo a la ciudad, y al mismo tiempo de unas regiones a otras, es incesante. En este trabajo, teniendo en cuenta los datos que nos ofrece esta realidad, se estudia si la vivienda, convenientemente fomentada y protegida por las Administraciones Públicas en los pequeños municipios, puede constituirse en un medio que coadyuve a evitar la sangría demográfica que sufren, contribuyendo así al denominado reto demográfico. A tal fin, se analiza la protección de la vivienda rural en la actualidad y se exponen los modelos habitacionales más idóneos para favorecer el desarrollo rural. También se proponen unas medidas programáticas complementarias, pero necesarias para la consecución de este objetivo
Mechanical Properties Characterization of Glass/Carbon Fiber Hybrid Multilayer Composite under Environmental Aging Condition

Published: March 2024

Metallic components in boating industry are being replaced with carbon fiber composites due to their light weight, excellent mechanical properties, and corrosion resistance. However, the carbon fiber cost has obstructed the substitution. Hybridization is suggested to merge carbon and glass fibers in cost-effective composites while maintaining the desired engineering properties. This study experimentally examines the impact of hybridization and seawater aging on the mechanical properties of glass and carbon fibers hybrid composites. A range of composites ([C]6, [CGC]s, [C]3[G]3, [GCG]s, and [G]6) are fabricated and aged in simulated seawater solution before their tensile, flexural, impact, and hardness properties are examined. The results revealed degradation in properties due to the ageing, the degree of degradation is influenced by the s hybridization configuration. The [G]6 sample shows the highest tensile strength reduction of 30% compared to 20% for the [C]6. The remaining samples exhibit reduction percentages falling between these two extremes. A similar behavior is observed in the flexural test, though the extremes values are smaller, 10.2%, and 12.5%. The impact and hardness tests showed an inverse relationship between the glass fiber content and impact strength degradation due to aging, while they exhibited a linear correlation for hardness degradation due to ageing.
