RESUMO Com objetivo de verificar as condições higiênico-sanitárias de ovos comerciais de vários fornecedores da região de Descalvado, estado de São Paulo, foram avaliados, no período de 17/1/ 98 a 28/12/98, 48 amostras compostas por 30 ovos cada. Os gêneros Escherichia, Enterobacter, Citrobacter e Klebsiella, formam o grupo denominado coliforme que diferencia-se em dois grupos: total e fecal. Os ovos foram analisados no Laboratório de Patologia Avícola de Descalvado, onde foram assepticamente manipulados e processados de acordo com as técnicas bacteriológicas específicas para isolamento e identificação destes microorganismos. Obteve-se crescimento de coliforme total em 33,3% e de coliforme fecal em 8,33% das amostras. Estes resultados indicam que é necessário uma melhora na manipulação e acondicionamento desses ovos, considerando os padrões de comparação em ovos frescos para estes microorganismos de acordo com a Secretaria de Vigilância Sanitária do Ministério da Saúde.

Published: September 2024

ABSTRACT The genus Pison Jurine (in Spinola), 1808 (Hymenoptera: Crabronidae) was revised by Menke, 1988 and three subgenera were placed in synonymy with Pison: Pisonoides F. Smith, 1858; Krombeiniellum Richards,1962 and Entomopison Menke, 1968a. The genus includes 42 native species in the Neotropical Region and more of the half of these are found in Brazil. Some of them make mud nests on diverse substrates, such as: on the underface of broad leafs, on the wall of human constructions, boxes, windows, and in the edges of roofs. The coccons of some of these species are closed cells with a fine layer of mud in a small abandoned nest (made on vegetable fibres) of Mischocyttarus de Saussure, 1853 sp. (Hymenoptera.: Vespoidea, Vespidae, Polistinae, Mischocyttarini). This is the first record of nesting behavior for this species. Male of P. duckei is still undescribed. The third specie observed was P. delicatum Menke, n sp.

RESUMO Avaliou-se o efeito tóxico "in vitro" de seis produtos fitossanitários utilizados para controle de Leptopharsa heveae na cultura da seringueira sobre os isolados dos fungos Beauveria brongniartii (619); Verticillium lecanii (972); Metarhizium anisopliae (1144 e 1189); Paecilomyces fumosoroseus (1200), Sporotrix insectorum (1229) e Beauveria bassiana (1196). Os produtos foram adicionados em concentrações proporcionais às que são utilizadas em condições de campo em meio de cultura BDA, quando este ainda encontrava-se em estado líquido, sob a temperatura de, aproximadamente, 50º C. Após a solidificação do meio em placa de Petri, foi feita a inoculação dos microrganismos, em três pontos por placa. Decorridos 10 dias, as placas foram retiradas da incubação (câmara tipo BOD, com 26 ± 0,5° C, 70 ± 10% UR e fotofase de 12 horas), fazendo-se a avaliação do diâmetro médio das colônias e da produção de conídios. Decis e Nuvacron foram compatíveis com B. brongniartii (619). A maioria das combinações, com exceção da formulação de Decis foi compatível com V. lecanii (972). O fungo M. anisopliae (1144) foi muito sensível para todas as formulações, com exceção do isolado 1189, que não foi suscetível às formulações de triclorfon, carbosulfan e metamidofós, o que mostra a variabilidade genética de uma mesma espécie de fungo. Nuvacron e Stron foram compatíveis com B. bassiana (1196), P. fumosoroseus (1200) e S. insectorum (1229). Marshal foi compatível com B. bassiana (1196) e S. insectorum (1229) e Dipterex foi compatível com P. fumosoroseus (1200).

ABSTRACT The objective of this study was to determine the effects of height within the canopy, leaf chemical composition, levels of leaf nitrogen and potassium, densities of leaf trichomes and crystalliferous idioblasts, natural enemies, total rainfall and median temperature on the intensities of Myzus persicae (Sulzer) (Homoptera: Aphididae) and Frankliniella schulzei (Trybon) (Thysanoptera: Thripidae) attacks in six tomato plantations Lycopersicon esculentum var. "Santa Clara" in two counties in Brazil. Our results indicate that M. persicae can be an important tomato pest in regions of mild temperature while, F. schulzei, can be in higher temperature regions. F. schulzei tended to attack in the initial phase of the culture while M. persicae, from the middle to the final phases. Both M. persicae and F. schulzei concentrated their attack on the leaves in the apical part of the plants rather than in the middle and basal parts. Natural enemies, especially the parasite Adialytus spp. (Hymenoptera: Braconidae) and spiders, can be important agents for the control of the aphid and thrips population in tomato, respectively. No correlation was detected between levels of leaf N and K, leaf chemical composition, leaf trichome (99.65% non-glandular), and crystalliferous idioblasts with these pests.

RESUMO Nos estudos relacionados com dissipação e contaminação de agrotóxicos são necessárias determinações de sua presença e das quantidades no ambiente. Esta determinação quantitativa é possível após a utilização de métodos eficientes de extração. Testes preliminares são normalmente efetuados para estabelecimento da melhor metodologia de extração dos princípios ativos da matriz. A eficiência de alguns métodos de extração de diferentes agrotóxicos foi estudada em diversas matrizes (solo, tecidos animal e vegetal) usando-se técnicas radiométricas. A extração por metanol usando-se soxhlet foi a mais eficiente para a maioria dos agrotóxicos: aproximadamente 100% para atrazina, simazina e trifluralina; 99% para paration etílico; 98% para DDE; 95% para DDT; 91% para endossulfan; 90% para monocrotofós; 88% para paration metílico; 81% para acefato; 80% para carbaril e 75% para deltametrina. Já para o 2,4-D, o sistema de solventes mais eficiente (86%) foi composto de acetonitrila: água: ácido acético e extração por agitação mecânica. O metalaxil foi eficientemente extraído (aproximadamente 96%) utilizando-se acetato de etila como solvente e agitação mecânica. Para hexaclorobenzeno e paraquat as metodologias mais eficientes foram respectivamente, soxhlet com solução de hexano: acetona, e aquecimento sob refluxo com ácido sulfúrico (98% e 94%, respectivamente).

ABSTRACT This paper reports the death of a wild, subadult male of a southern brown howler monkey (bugio-ruivo), Alouatta guariba clamitans. The animal was found dead by the owner of a 60 ha. farm (Fazenda São Maximiano), located along the interstate road BR-116, km 308, Guaíba, State of Rio Grande do Sul, southern Brazil, 30º10'46,74"S, 51º23'30,78"W, in August 2000. The paper also describes the specimens of Trypanoxyuris (Trypanoxyuris) minutus found in the cecum. All organs were examined for helminths but were negative, except the cecum, which was full of macerated leaf litter and nematodes. The cecum wall was hyperemic, very thin, and distended, possibly by the large volume of material present. All the cecum contents were suspended in 5 liters of 0.85% saline physiological solution, from which a sample of 10% was taken and thoroughly examined. Six thousand one hundred and eighty-seven nematodes were counted in the sample (males + females). A total of 61,870 helminths were estimated in the entire cecal infrapopulation.

Published: September 2024

Abstract This article presents the lived and reflected experience of an Afro-centered psychology pilot study group. In addition to promoting collective studies, the group also aimed to experiment with an anti-racist inspired pedagogical-therapeutic methodological approach, aiming to promote processes of personal and professional Afrocentration. The group consisted of five psychologists from Brazil and Angola who shared a prior interest in the study. They met online monthly between July 2020 and August 2021. The reflections produced at each meeting were recorded in minutes. These records were collectively organized and analyzed to identify units of meaning. The reflections point to challenges in Psychology: 1) the need for Brazilian and Angolan psychology to open to authors who produce from Africa and the diaspora; and 2) the need for reflection and knowledge production based on the potential of traditional African and Afro-Brazilian practices as therapeutic tools.
Neurobiological origins of impulsive behavior in adolescence: possibilities of physical exercise
Authors: Martinez Victor Matheus Lopes , Martins Maiara da Silva
Published: September 2024

Abstract Objective This article aimed to understand the neurobiological origins of adolescent behavior and how the possibility of practicing physical exercises can attenuate the maturational tendency for impulse behaviors in this age group. Method For this purpose, a bibliographic research of a narrative nature was carried out in the databases SciELO, Web of Science, PubMed, and in books. Results The data revealed that during adolescence there is a propensity as a function of neurobiological development to search for rewarding behaviors in the short term. In this sense, bodily practices, including exercise, can be an essential component in the search to increase the neural control of impulses through a neurobiological and sociological bias. Conclusion It is concluded that exercise can be a propelling means in the search to attenuate the immediate and even risky behaviors of the adolescent brain, increasing higher cognitive functions with this better cortical control.

Published: September 2024

Abstract Objective The present study aimed to adapt the Anxiety Symptoms Questionnaire and analyze its psychometric properties for the Brazilian population. Method The adaptation was conducted in six stages: translation, synthesis, back translation, expert analysis, evaluation by the target population, and a pilot study. A total of 441 adults (M = 35.36; SD = 11.08 years) were interviewed, with 301 classified as healthy, 105 as having anxiety, and 35 as having depression. Results The Anxiety Symptoms Questionnaire results demonstrated evidence of content validity, exhibiting high internal consistency (Cronbach’s alpha = 0.975 and McDonald’s omega = 0.976). Moreover, the questionnaire showed evidence of criterion validity by effectively distinguishing between groups with and without anxiety (F(2.438) = 22.647; p < 0.01), as well as convergent validity with the structured clinical interview for DSM-5 (ρ = 0.70, p < 0.01), and correlations with anxiety (ρ = 0.62, p < 0.01), depression (ρ = 0.64, p < 0.01), and stress (ρ = 0.70, p < 0.01) scores from another instrument. Conclusion The Anxiety Symptoms Questionnaire is valid and reliable for use by healthcare professionals in the Brazilian population.

Abstract Objective This study aimed to analyze the narratives of social educators regarding their practices within a foster care institution for children and adolescents in South Brazil. Method A narrative interview script and a sociodemographic questionnaire were employed in the investigation, involving eleven participating social educators. The interviews underwent grounded theory analysis, resulting in four emergent categories pertaining to practices (initiation, types, dimensions, context). Results The practices initiate in a straightforward manner and unfold gradually through caregiving, the incorporation of play, and affection. Notably, aspects of comprehensive care and humanized attention were identified. Conclusion The results underscore that these practices adhere to guidelines outlined by public policies. However, they also emphasize the need for continuing education to discuss specific aspects of care and strategies for evaluating the undertaken activities.
Peculiarities of the Formation of Benthic Algae Communities in the Kyiv Reservoir (Ukraine)
Authors: Davydov O. A. , Koziychuk E. Sh.
Published: September 2024

The main structural and functional indices of benthic algae communities of the Kyiv Reservoir, including species richness, numbers, biomass, and the composition of leading complexes, are given in the paper. Totally, 199 algal species and infraspecific taxa, including those containing nomenclatural types of species, were identified. Bacillariophyta, Chlorophyta, and Cyanobacteria were highly diverse in their species composition. A polymixed ecotopic algal community,
including both resident species (benthos organisms) and those introduced from other biotopes (plankton and periphyton organisms) is formed at the bottom of the reservoir. In the shallow water zones of the reservoir, the structure and
abundance of microphytobenthos are formed mainly by benthos organisms, whereas in the deep water zones its formation depends on the intensity of sedimentation of plankton forms of algae from the water column to the bottom under specific hydrological conditions. Beta-diversity is determined mainly by the circulation (replacement) of species, and the nestedness component of the species structure is insignificant. Species sorting prevails among different types of microphytobenthos spatial dynamics, and manifestations of the "mass effect"
are also noted.

Published: September 2024

Active producers were selected as a result of studies on the ability of exoproteases of supernatants of culture liquids of bacteria isolated from bottom sediments of the Black Sea to hydrolyze fibrin, fibrinogen, and collagen. It was shown that partially purified enzyme preparations of Bacillus subtilis 248 and Bacillus subtilis 231 differed in physicochemical properties. Thus, the fibrin-(ogen)olytic activity of B. subtilis 248 has a pH optimum of 9.0, and the thermooptimum of fibrinogenolytic activity is 4-20 °C, while that of fibrinolytic activity is 15-20 °C. The partially purified enzyme preparation B. subtilis 231 has two pH optimums of fibrin(ogen)olytic activity - 7.0 and 11.0, and the thermooptimum - 37 °C. It was established that Bacillus subtilis 248 and Bacillus subtilis 231 may be promising for further scientific research as producers of proteases with α/β/γ-fibrinogenase and α/β-fibrinase activity.
Migration Capacity and Bioavailability of Metals in Bottom Sediments of Surface Water Bodies (Chemical and Analytical Aspects)
Authors: Linnik P. M. , Zhezherya V. A. , Linnik R. P.
Published: September 2024

The paper summarizes results of the study of the coexisting forms of metals (Cd, Pb, Mn, Co, Cu, Zn, Fe, Cr, and Al) in bottom sediments of surface water bodies of various types, in particular the reservoirs of the Dnieper cascade and small water bodies of the urbanized territories (for example Lake Verbne) located in the city of Kyiv. On the whole, five fractions - ion exchange, carbonate, oxide, organic/sulfide, and residual, including the metals found in the crystal lattice of minerals, were obtained using the five-stage extraction technique. It has been found that the distribution of metals between the specified fractions significantly differs due to the chemical properties of metals and the type of bottom sediments. The major portion of cadmium is concentrated in the first three fractions of bottom sediments and therefore it is characterized by the highest migration capacity. An increase in water mineralization and a decrease in pH values in the near-bottom layer of water are the most important factors contributing to cadmium migration from bottom sediments. Therefore, this metal should be considered
as potentially bioavailable to aquatic organisms. The lowest migration capacity is characteristic of aluminum, copper, chromium, and lead occurring mainly in the composition of organic/sulfide and residual fractions. These metals migrate from the bottom sediments under specified conditions, the probability of the occurrence of which in the natural aquatic environment is rather low. Thus, these metals belong to the category of poorly available for hydrobionts. Iron and manganese, as well as those metals, the share of which is quite high in the composition of Fe(III) and Mn(IV) oxyhydroxides occupy an intermediate position. Zinc and partly cadmium, cobalt, and lead belong to this group of metals. The
migration of these metals from bottom sediments increases significantly with long-term oxygen deficiency in the near-bottom layer and the formation of anaerobic conditions. These research results are relevant under conditions of climate
changes that occur now and will occur in future, as the risk of secondary pollution of the water environment of surface water bodies by various chemical substances, including metals, due to their migration from bottom sediments increases. Dissolved oxygen deficiency in surface waters, salinization of fresh water, and the increase in the concentration of organic substances and decrease in pH and Eh-potential in the near-bottom layer of lakes and reservoirs contribute to the increase of secondary pollution of the water environment by metal compounds. The urgency of this problem makes it necessary to perform such research at the present time.

Drained and undrained behaviour of a sandy silt gold tailings under general multiaxial conditions
Authors: FANNI RICCARDO , REID DAVID , FOURIE ANDY
Published: September 2024

A laboratory study was carried out on a sandy silt gold tailings to investigate the effect of the Lode angle (θ) on the critical state line (CSL) in the compression (e–p′) and effective stress (q–p′) planes, and to study the strength anisotropy of the tailings. Four sets of strain-controlled tests were carried out: (a) drained and undrained triaxial compression tests; (b) torsional shear hollow cylinder tests under drained and undrained conditions at constant θ and constant direction of the major principal stress relative to the vertical axis (α); (c) drained and undrained triaxial extension tests; and (d) undrained hollow cylinder simple shear tests. The tests were carried out on loose moist tamped (LMT) and dense slurry air-dried (AD) prepared specimens. The results indicated that: (a) the CSL in the compression plane does not depend on θ or on the stress path; (b) the stress-dilatancy is dependent on θ while the effect of θ on state-dilatancy is minor; (c) the undrained yield strength of LMT was found not to depend significantly on the state parameter (ψ), but it was significantly affected by the stress path followed during consolidation and subsequent shear, for example, by the pre-shearing stress ratio, stress-reversal loading, θ and α. The results demonstrate the contribution of the initial shear stress and evolving anisotropy on the undrained strength of the gold tailings in a loose state.
Reliability of dynamically embedded anchors in soft clay
Authors: Tom Joe G. , D. O’Loughlin Conleth , White David J.
Published: September 2024

Floating offshore infrastructure requires geotechnical anchorage for station-keeping. Dynamically embedded anchors are anchors that free fall through the water column and embed in the seafloor through kinetic energy at impact, enabling efficient installation into soft seabeds. Dynamic installation of plate anchors is an alternative to static embedment methods, such as suction-embedded plate anchors. This paper uses a numerical installation and capacity methodology to explore the factors that control dynamically embedded plate anchor (DEPLA) capacity and to compare DEPLA reliability with that of statically embedded plate anchors for two sets of seafloor properties that represent different types of geotechnical uncertainty. Probabilistic Monte Carlo simulations are presented for the two representative conditions using the distribution of the tension loads for an example catenary-moored system. The results quantify the smaller influence of soil strength uncertainty on DEPLAs compared to statically embedded plates. The smaller influence arises due to dynamically embedded anchors reaching a deeper embedment in softer soil, counteracting the lower strength. This leads to increased reliability compared to statically embedded equivalent anchors installed to a specified depth. The authors quantify the reduction in safety factor that could be used for dynamically embedded anchor design to achieve similar levels of reliability compared to statically installed anchors of the same size.
Characteristics of alkali-activated composites containing blast-furnace slag aggregate and ferronickel slag powder

Published: September 2024

The use of alkali-activated composites and alternative aggregates reduces the carbon dioxide emissions of the construction industry and mitigates the problem of aggregate depletion. However, published investigations into non-cement composites containing ferronickel slag powder (FSP) and blast-furnace slag fine aggregate (BSA) are limited. The aim of this study was thus to assess the mechanical properties and durability of non-cement composites containing FSP and BSA. The mix with 10% FSP and 25% BSA was found to have the highest 28-day compressive strength, of approximately 42.2 MPa. For the mixes with 5% FSP, the 28-day compressive strength increased with an increase in BSA content. Charge-passed tests revealed that, after 7 days, the sample with 5% FSP and 50% BSA exhibited a total charge of approximately 907 C, classifying it as ‘very low’ according to ASTM C1202. By 56 days, the total charge for this sample reached a value of approximately 120 C, close to ‘negligible’ as per ASTM C1202. It was thus concluded that an appropriate BSA content effectively enhances the mechanical properties and durability of non-cement composites.
Flexural behaviour of normal concrete circular beams strengthened with ECC and stainless steel tubes

Published: September 2024

The use of laminated fibres for strengthening reinforced concrete beams is challenging owing to bonding and compatibility issues, especially in scenarios where cost effectiveness and long-term performance are important. A novel flexural strengthening technique for normal concrete circular beams (NCCBs) is proposed, using engineered cementitious composites (ECCs) and stainless steel tubes (SSTs). To examine the application of the proposed strengthening method, five NCCBs were fabricated and tested under static loading until failure to investigate the effects of ECC thickness and SST thickness. The test results showed that the strengthening technique greatly improved the failure pattern and the ultimate flexural capacity of the tested NCCBs, and the enhancement increased with an increase in the thickness of the ECC and SST. Using Abaqus software, finite-element models were constructed to simulate the performance of the tested NCCBs. The accuracy of the finite-element modelling was confirmed by comparing the simulations with the experimental results. The validated model was used for a detailed parametric investigation of the effects of the thickness of the ECC and SST on the failure and ultimate bending capacity of the strengthened beams.
Quantum Fundamentalism and Theological Liberty
Authors: Harris Mark
Published: September 2024

Quantum mechanics (QM) is astonishingly successful as a theoretical framework, underpinning countless scientific areas and providing the impetus behind entire technologies. Many scientists suspect that physical reality is fundamentally quantum in nature, even if we perceive little of this in our everyday human experience. This is the viewpoint of “quantum fundamentalism.” Yet, the conceptual implications of QM defy common sense, to such an extent that popular culture largely perceives of QM as a source of counterintuitive weirdness. At the same time, bestselling self-help manuals portray QM as a source of hidden healing power within, while spiritual readings invoke QM as a bridge to the divine, or as a source of theological analogies. Scientists often denounce these mystical approaches as “quantum quackery,” but I examine their serious side. I argue that, for quantum fundamentalism to function as a worldview, it should inform a sense of human purpose, something for which theological analysis is well equipped.
The Protection of Human Rights in South Africa: Unpacking the Duty of the State to Realise the Right to Development
Authors: Fobosi Siyabulela Christopher
Published: September 2024

The 1986 United Nations Declaration on the Right to Development (DRTD) presents a multifaceted framework that blends political aspirations with principles from international human rights treaties. Advocating "people-centered development" places individuals at the forefront, empowering them as principal beneficiaries of development efforts. According to Article 2 of the DRTD, both state and non-state actors are responsible for formulating inclusive national development policies to continually enhance the well-being of the entire populace. This involves ensuring active, accessible, and meaningful participation in development processes and fair distribution of the resulting benefits. South Africa's duty to realise the right to development comes under scrutiny in this context. Despite its obligations under international instruments like the African Charter, challenges persist in effectively implementing developmental advancements. This includes fields critical for sustainable progress, such as renewable energy, biotechnology and information technology. Furthermore, the COVID-19 pandemic has exacerbated existing obstacles, straining resources and threatening to reverse recent developmental gains. Budget constraints, particularly in the research and development sectors, hinder progress towards meeting development objectives. Therefore, while the DRTD and other international instruments emphasise the importance of the right to development, critical debates regarding its scope and implementation persist. Addressing these issues requires a nuanced understanding of development dynamics, balancing global aspirations with practical considerations. It necessitates collaborative efforts to refine and operationalise the right to development, ensuring equitable progress and sustainable development for all.

Published: September 2024

En este trabajo se presentan aspectos relevantes de la vida de la Sagrada Familia, la misma que ha sido descrita por el Vaticano II, y que ha sido una preocupación constante para el Magisterio de la iglesia, la “ecclesia doméstica” o Iglesia del Hogar, que ha sido llamada a salvaguardar la tradición cristiana (Vega y Porra, 2014). Además, analiza el contexto de la esencia de la Sagrada Familia, y la establece como un ejemplo a seguir para toda familia cristiana, lo cual fue ratificado posteriormente por Juan Pablo II. Estos archivos conciliares han sido origen de inspiración para las reflexiones teológicas con respecto a la familia. La iglesia celebra una fiesta en nombre de La Sagrada Familia conformada por María, José y Jesús para conmemorar su relevancia. Para muchos autores, la iglesia doméstica ha ido en aumento en la santidad teniendo como dirección la Sagrada Familia tal como lo destacaba Juan Pablo II, “es el comienzo de muchas otras familias santas” (Vega y Porra, 2014, p. 179). La Sagrada Familia es un ejemplo y modelo para seguir para la familia cristiana, pues se destaca la vida sencilla y armoniosa de una familia. El nacimiento de la Sagrada Familia significó el comienzo de los tiempos de fe y amor filial, para la cual Dios escogió un hogar en el que pudiera nacer su hijo y entregar así todo su amor a los humanos. “Esa voluntad divina se cumple mediante ciertas circunstancias normales y ordinarias; una mujer que da a luz, una familia, una casa”.

Authors: Zhang Wei-Guang
Published: September 2024

Three mononuclear nickel(II), cadmium(II) and zinc(II) complexes, [NiL2]·2CH3OH·H2O (1), [CdI2(HL)]·CH3OH (2) and [ZnL2] (3), have been synthesized from 3-hydroxy-4-methoxy-N’-[(Z)-(pyridin-2-yl)methylidene]benzohydrazide (HL) by microwave irradiation method. All complexes were characterized by CHN elemental analyses and infrared spectra. Structures of the complexes were further studied by single crystal X-ray determination, which reveals that the Ni and Zn atoms in complexes 1 and 3 are in octahedral coordination, and the Cd atom in complex 2 is in square pyramidal coordination. The biological activity of the complexes on the bacterial strains Bacillus subtilis, Staphylococcus aureus, Pseudomonas aeruginosa and Escherichia coli was evaluated. As a result, the zinc complex has interesting antibacterial activities.

This protocol is used for successful NGS library preparation from total RNA of animal tissue samples. With this method we obtained full-length paramyxovirus genomes using the Illumina sequencing platform. It works most efficiently on RNA viruses possessing a polyA tail, but it can also be used for sequencing any other RNA viral sequences originating from tissue samples.
USDA LTAR Common Experiment measurement: Soil water content v1
Authors: H. Cosh Michael , Baffaut Claire
Published: September 2024

Soil water content, also known as soil moisture, is commonly defined as the volume of water per volume of soil (volumetric soil water content). Gravimetric soil water content is the weight of water per weight of soil. For most purposes, we speak of volumetric water content in the units of m3/m3. Soil water content usually refers to the water contained within the vadose zone of the surface soil layer. Soil water content below the saturated water content of the soil usually ranges from 0-0.5 m3/m3.
Exploring the Coverage of the Scientific Production of the University of Bologna in OpenCitations v2
Authors: Zilli Leonardo , Andreose Erica , Di Marzo Salvatore
Published: September 2024

We present a step-by-step methodology for tracking the coverage of publications available in the CRIS (Current Research Information System) infrastructure of the University of Bologna and implemented in the IRIS platform, within the databases of OpenCitations. The methodology filters and transforms data dumps from IRIS and OpenCitations Meta and Index to create novel datasets that are used to perform quantitative analysis on the subject matter. Specifically, we quantify the proportion of IRIS publications included in OpenCitations Meta, examine the types of publications best covered, evaluate the number of citations within OpenCitations Index involving IRIS publications as either citing or cited entities, and the extent to which these citations reference works outside of IRIS. The research questions addressed in the study are: What is the coverage of the publications available in IRIS (strictly concerning research conducted within the University of Bologna) in OpenCitations Meta? What are the types of publications that are better covered in the portion of OpenCitations Meta covered by IRIS? What is the amount of citations (according to OpenCitations Index) coming from the IRIS publications that is involved in OpenCitations Meta (as citing entity and as cited entity)? How many of these citations come from and go to publications that are not included in IRIS? How many of these citations involve publications in IRIS as both citing and cited entities?

Published: September 2024

La Ley 30 de 1992, en su artículo 1, señala que las instituciones de educación superior deben enfocarse en el desarrollo y articulación de procesos meticulosamente diseñados, cuyo objetivo primordial es asegurar y elevar la calidad de sus programas académicos. Esta normativa subraya la importancia de mejorar continuamente las actividades formativas, entre otros aspectos esenciales. En este marco, se destaca la necesidad de evaluar el servicio universitario o conocido también como prácticas formativas en salud, definidas por el Ministerio de Salud en Colombia como estrategias pedagógicas fundamentales que fomentan el desarrollo de competencias y conocimientos tanto en estudiantes como en docentes. Estas prácticas, que involucran activamente a estudiantes, educadores y la comunidad, son consideradas piedras angulares para el aseguramiento de la calidad educativa y la generación de un impacto social positivo. Se enfrentan a retos significativos, como la necesidad de adaptarse a contextos reales y a los constantes cambios en el ámbito educativo, lo que a su vez exige la implementación de nuevas estrategias pedagógicas y un eficaz manejo del cambio. Esto, con el fin de potenciar la enseñanza, la investigación y la proyección social, a través de la gestión educativa. El estudio realizado tuvo como finalidad explorar la gestión educativa en el servicio universitario de un programa de fisioterapia en la ciudad de Cali, Colombia, buscando promover un modelo educativo que sea inclusivo, participativo y resiliente.
El Principio de Congruencia en el Proceso Penal: Análisis Comparado
Authors: Betancur Soto Christian Felipe , Daza González Alfonso
Published: September 2024

El presente artículo investigativo surge de la actividad analítica e interpretativa de los autores, la cual se centra en el estudio del proceso penal en el contexto colombiano, de las instituciones jurídicas y principios que integran al mismo.
Se enfoca la temática de este documento en la necesidad de dar claridad sobre cómo opera el principio de congruencia en el derecho procesal penal, cuáles son los límites de la discrecionalidad que tienen las partes que integran el proceso, cual es el papel del juez respecto de las solicitudes que estos elaboran por medio de los mecanismos señalados en la norma, como lo es el escrito de imputación, el escrito de acusación y cuáles son los límites que tiene el juez en su rol de tercero imparcial de intervenir dentro del proceso para garantizar una calificación jurídica de los hechos que lleven a la verdad y la justicia.
Tomando principal relevancia en el ejercicio de derechos y obligaciones por parte de las partes, los que pueden llegar a ser limitados por el juez, pudiendo generar escenarios de extralimitación arbitraria de las funciones que la ley le otorga y vulnerando inclusive los preceptos constitucionales, el debido proceso y la discrecionalidad que se le otorga al fiscal sobre el ejercicio de la acción penal.
Límites Presupuestales de las Personerías Municipales y la Vigilancia de la Conducta Oficial: Análisis de Medidas Legislativas que Restringen el Control sobre la Función Pública
Authors: Gómez López Mateo , Betancur Corrales Juan Felipe
Published: September 2024

El propósito de este artículo es analizar la incidencia que tiene el límite presupuestal de las personerías en Colombia, es decir, se revisa si estos afectan la función de vigilancia de la conducta oficial de los servidores públicos que tales entidades adelantan conforme a la función constitucional establecida en el artículo 118 de la Constitución Política. La metodología utilizada es de carácter dogmático porque se aborda la legislación y los pronunciamientos de la Corte Constitucional que han subrayado la importancia de las personerías para prevenir, corregir y sancionar las conductas de los servidores públicos en Colombia. Las personerías atraviesan por graves dificultades dada la cantidad de funciones que se les han asignado por cuanto existe una discrecionalidad por parte de los alcaldes y de los concejos distritales o municipales en la asignación del presupuesto. Por tanto, es necesario un nuevo diseño de regla fiscal.
El imaginario sobre formación profesional y mercado laboral en jóvenes estudiantes de administración de la generación z. Análisis comparativo entre Francia y México
Authors: Romo-Morales Gerardo , Agulhon Sophie
Published: September 2024

In this article, we analyze the role played by the social imaginary of the young people of generation Z, in their formal education processes as well as in their professional learning. For this analysis we worked with students between the ages of 18 and 25 from Mexico and France. Specifically with Mexicans from different university centers of a public university in the State of Jalisco, and Frenchmen from equivalent institutions in the Paris region who study careers related to administrative sciences. We sought that the comparative analysis had correlational meaning, that the young participants, in addition to their age, had relatively similar socioeconomic conditions and cultural access. It is assumed from the beginning that we would find some significant differences in the institutional frameworks, however, the explicit intention was to focus on the coincidences that we could attribute to the study generation and its assumed global characteristics. This study consists of two main phases: in the first, semi-structured interviews were used as data collection, and in the second, the information obtained was analyzed in order to identify patterns and trends in the responses of the participants. In this way, we were able to characterize the social imaginary of generation Z linked to the world of work, and their constant and systematic doubts about institutions and their correlation with obtaining a good job. In general, the study is part of the analysis of the identity processes of the generations, and the weight that the imaginary and the institutions have in these.
Requerimientos del escritor intermedio para adquirir las competencias de escritor experto
Authors: Villarreal-C Elizabeth , Valetopoulos Freiderikos , Méndez Jeisson
Published: September 2024

The literature registers two main types of writers: novices and experts. However, in the process of their development, intermediate writers can also be found, who lack certain elements to reach maturity as expert writers. Thus, the objective was to identify the aspects that should be considered for the design of a device that allows the transformation of intermediate writers into expert writers. For this purpose, the characteristics of each group were analyzed, as well as the aspects that differentiate them, the deficiencies they present, the difficulties in their training, and their integration into a process of cognitive reconstruction. It is concluded that elements of planning and structuring of ideas should be incorporated into a training device that enables the structuring of more elaborate texts, helping writers to understand the importance of ensuring that the ideas they write truly reflect the message and knowledge they want to convey.
