Published: December 2023

The presence of Law Number 5 Year 1999 on the Prohibition of Monopolistic Practices and Unfair Business Competition is a real effort for the state to reform the law in the field of economics and business competition law. Against the condition of Indonesia in the vortex of economic globalization that intersects with foreign business actors, there are legal issues that arise are related to the legal position of foreign business actors within the framework of the principle of extraterritoriality jurisdiction and how to anticipate the negative impact of anti-competitive actions committed by foreign business actors based on the principle of extraterritoriality to realize legal certainty. The method used in this research is normative and analytical descriptive research, using secondary data and analyzed qualitatively. The result of the research is the need for improvement and reformulation of the legal position of foreign business actors in the context of extraterritorial jurisdiction in modern competition law. Renewal of business competition law is a necessity considering the needs and dynamics of business competition law that is growing rapidly in the era of global trade. KPPU's institutional strengthening must be carried out continuously and policy innovations must be implemented continuously to adjust to the current needs of competition law.

The social protection aspect of the subjective assessment of the material security of large and foster families: the results of a comparative qualitative study
Authors: Karpikova Irina Serafimovna
Published: December 2023

Modern demographic trends in the field of fertility have led to increased state attention in recent years to issues of social protection of motherhood and childhood, social support for families with children. This trend has resulted in a significant increase in the list and volume of social benefits and other social benefits, and an increase in the number of their recipients. The issue of evaluating the effectiveness of measures taken by the state is becoming increasingly relevant, not only from the standpoint of quantitative statistical indicators, but also by studying the opinion of beneficiaries. The article presents the results of a study aimed at determining subjective assessments of the material security of families with children in connection with their receipt of social protection and support measures. The object of the study is families with children belonging to the categories of large and foster families. By the method of in-depth qualitative interviews, representatives of households of 10 large families and 10 foster families living in large and small cities of the Irkutsk region were interviewed. The author has revealed significant differences in assessments between representatives of different categories of families with children. Large families express dissatisfaction with the following positions: the availability and amount of social benefits; the amount of benefits and the complexity of obtaining them. In conditions of dependence of social benefits on the size of the per capita income of family members, the status of having many children ceases to play a social protection role, not being a significant factor in ensuring the material well-being of the family. On the contrary, foster families note: a significant increase in the amount of payments for the maintenance of foster children and the remuneration of foster parents; an increase in the list and volume of additional social support measures. These measures have made it possible to increase the level of financial security of foster families. Foster parents expressed the need to take into account the needs of foster children not only of a minimal nature, but also related to their development, health maintenance, and additional education. The results obtained made it possible to formulate approaches to solving problems of a social protection nature of the considered categories of families with children. For foster families, it is important to gradually expand measures of social support for foster children based on monitoring needs. In relation to large families, it is necessary to radically change the social protection mechanisms based on the recognition of the status of having many children, which gives the right to receive additional social guarantees.

Published: December 2023

Periodic orbits are widely used in space missions and are fundamental for us to understand the complex dynamic system of circular restricted three-body problem. However, there are still many potential families of periodic orbits that have not been located and computed. This study aims to generate some new and less-known families of periodic orbits for the Jupiter–Callisto system to obtain an extended database. The numerical methods for the computation and continuation of periodic orbit families are provided. Five bifurcation diagrams are explored in depth, and 108 periodic orbit families are located. Of these, 59 families are continued to the entire families. Twenty asymmetrical families also come into view. New discoveries and the characteristics of several particular families are presented and discussed. Synodic resonant periodic orbits appearing under the perturbation of Ganymede are also identified. The expanded families of periodic orbits are expected to provide a reference for future Callisto exploration mission design.

Published: December 2023

As part of the UK Research and Innovation project New Aviation, Propulsion, Knowledge and Innovation Network (NAPKIN), a high-level framework was developed for the assessment of the noise impact of the proposed regional-sized hydrogen-powered aircraft. This study consists of the methodology used to generate the industry-standard noise–power–distance (NPD) curves from individual component noise analysis, specifically propeller tonal noise. The model is based on an asymptotic analysis of a frequency domain propeller tonal noise model combined with a linear approximation, taking advantage of the logarithmic nature of noise. An error analysis on the linear approximation assumption proves that the relative error between predicted and actual values of the noise remains below 10% for appropriately chosen baseline points. Verification of the framework was achieved through a bench-marking procedure that compared predictions of departure NPD curves for current technology regional aircraft against published ones over a range of operational power settings. Finally, departure and approach NPD predictions for three of the NAPKIN hydrogen concept aircraft are presented. Concepts featuring a larger, slower-rotating propeller with an increased number of blades relative to the reference aircraft showed benefits over the reference aircraft, despite, in some cases, increases in maximum takeoff weight.

Published: December 2023

The evolution of shock waves in a combustor is a complex process comprising multiple time series, which results in a long computational cycle for unsteady numerical simulations. Current data-driven methods integrating physical information provide novel opportunities to rapidly and accurately predict the flowfield in the combustor. In this study, we construct a dataset under Mach numbers from 2 to 5 based on a self-designed scramjet combustor model and propose a physical convolutional neural network flowfield reconstruction method based on channel interaction (PICNNCI). This method embeds Euler equations that characterize the flow characteristics of inviscid fluids as physical constraints to solve the low-accuracy problem of traditional convolutional neural networks arising due to insufficient prior information. The model first performs dimensional transformations on temporal and spatial information input and converts a one-dimensional column vector into a two-dimensional vector to meet the convolution operation rules. Then, convolution is used for feature extraction to output the predicted flowfield, including velocity, pressure, and density fields. Finally, the predicted flowfield is optimized using the Euler equation and compared with the results obtained by numerical calculation and traditional neural network methods. The average peak signal-to-noise ratio of PICNNCI reaches 34.01 dB, and the linear correlation reaches 0.994.

Authors: Rampal Parikha , Sachdev Namrita , Khurana Rajat , Taneja Anil
Published: December 2023

Objectives:

Juvenile idiopathic arthritis (JIA) is a common cause of morbidity and consequent disability among youth up to 16 years of age. Our study aims to image the ankle joints of JIA patients and correlate the findings with the clinical disease activity scores. Juvenile Arthritis Disease Activity Score (JADAS-27) is used by pediatricians to assess disease activity in JIA patients. There are four factors that determine this score – Global assessment of disease activity by the physician as well as patient/parent, joint count with active disease, and erythrocyte sedimentation rate (ESR). However, these clinical scores are dependent on the clinician’s experience and observation and, therefore, subjective.

Material and Methods:

Thirty patients of either sex with a clinical diagnosis of JIA as per the International League of Association for Rheumatology definition with clinically involved ankle joints were included in the study. Chronic arthritis due to other causes, such as infection, trauma, and so on, was excluded. All clinically diagnosed cases of JIA were subjected to magnetic resonance imaging (MRI) evaluation on Siemens Skyra 3 Tesla High-Resolution MR system using a dedicated coil for the ankle joint. Six sub-joints for each patient are evaluated, namely - The tibiotalar joint, subtalar joint, calcaneocuboid joint, calcaneonavicular joint, naviculocuneiform joint, and tarsometatarsal joint. Image analysis and scoring shall be done for each patient at each joint as per the Juvenile Arthritis MRI SCORE, consisting of the following parameters-synovial hypertrophy score, cartilage lesion score, bone erosion score, and bone marrow change score. Each of these scores is calculated individually based on the percentage of involved bone volume. All individual scores were summed to get the total MRI Score. The data collected were then statistically analyzed.

Results:

A positive correlation was sought between the JADAS-27 score and the total MRI score with the P-value being 0.03. A positive correlation was also found between the total MRI score and the ESR value of the patient (P - 0.02).

Conclusion:

MRI findings can be a potential marker of disease activity in JIA patients and these findings could also predict the prognosis accurately in these patients. The findings are objective and comparable to the aforementioned clinical scores.

These results provide valuable information for the development of effective educational strategies aimed at strengthening patriotic values among the younger generation in the region.
Reproduction of fixed assets in the Republic of Sakha (Yakutia): an analysis of the state and direction of development
Authors: Noeva E. E.
Published: December 2023

Fixed capital is an important component of any business. It provides long-term benefits that positively impact financial performance. One of the significant benefits of investing in fixed assets is that it helps improve the efficiency and productivity of a business entity. For example, investing in modern equipment or machines allows you to increase production speed, reduce losses, reduce maintenance costs, and create the prerequisites for the long-term sustainable development of any company. The provision of fixed assets, their general condition, and technological level determine the competitiveness of the national economy. This article, in addition to some theoretical aspects that form the basis for the study, presents an assessment of the state of fixed assets in the Republic of Sakha (Yakutia) in comparison with all-Russian indicators. In general, with regard to the state and development of fixed capital, the situation in the Republic of Sakha (Yakutia) is quite favorable; however, if we consider the emerging trends from an industry perspective, significant disproportions become obvious both in the structure of investments and in the rate of reproduction of fixed assets. Such industries as construction, information and communications, and manufacturing are characterized by a high degree of depreciation of fixed assets in the Republic of Sakha (Yakutia). However, the areas of greatest interest to investors are subsoil use, as well as cargo transportation and storage. The purpose of investment in most cases is not technological development, which leads to qualitative changes and is the basis for the sustainable development of enterprises, but simple reproduction.

Authors: Kirillina E. I. , Ushnitskaya L. E.
Published: December 2023

The regional budget is a tool through which regional government institutions obtain resources to support their activities and fulfill the region’s development tasks. These resources include revenues from the use of regional property, tax receipts from the population and businesses, funding from the federal budget, and others. Through the budget, regional authorities have the opportunity to plan and implement investment projects, support small and medium-sized businesses, finance education, healthcare, culture, and other areas of activity. Consolidation of resources through the regional budget allows for the reduction of inequality between different territories, the improvement of the standard of living for the population, and the promotion of sustainable regional development. An important aspect of the regional budget is also the ability to plan and adapt to changing economic conditions, prevent financial crises, and ensure the financial stability of the region. This article explores the formation of the budget and resource allocation in the Sakha Republic (Yakutia). The importance of studying this topic is due to the fact that the system of interbudgetary relations plays a significant role in ensuring the socio-economic development of the region. The Sakha Republic (Yakutia) is a major resource-rich region, and interbudgetary relations have particular relevance as a significant portion of the region’s revenue is associated with the extraction and export of natural resources. The aim of the study is to analyze the distribution of income and expenditure in the region. The methodological basis of the research consisted of analyzing official statistical information on the budget’s income and expenditure in the Sakha Republic (Yakutia), as well as using methods of economic analysis and planning. The study examines and analyzes the revenue and expenditure of the consolidated budget of the Sakha Republic (Yakutia), analyzes the relationship between gratuitous receipts and own funds in the republic, and also examines interbudgetary transfers to the budget of the Sakha Republic (Yakutia).

Authors: Gulyaeva I. V. , Skryabinа I. V.
Published: December 2023

The climatic features of the Sakha Republic (Yakutia) require increased reliability of engineering life systems, and therefore the volume of housing and communal services provided far exceeds the average Russian indicators. One of the backbone enterprises in this industry is Vodokanal JSC. Vodokanal JSC is a monopolist in the field of water supply and sanitation and plays a key role in the economic and social development of the republic. The relevance of the study is explained by the fact that fixed assets provide the material and technical possibility of providing residents of the city of Yakutsk with high-quality drinking water and sanitation services. Maintaining fixed assets in normal technical condition and improving their use is the key to the success and reliability of any enterprise. The purpose of the research is to study the role of fixed assets in the activities of Vodokanal JSC. The analysis of literature sources shows a variety of methods for analyzing fixed assets. The authors selected two main areas: an analysis of the condition and movement of fixed assets and calculation of indicators of their effectiveness. The analysis showed that the fixed assets are generally in satisfactory condition, as evidenced by the calculated indicators of the efficiency of stock return, capital coefficient, and stock ratio. The main ways to improve the use of fixed assets are proposed. To conduct the study, the data of the financial statements of Vodokanal JSC were used, general scientific methods and techniques of the study were used.
A Comparison of Estimated and Actual Indicators of Flood Damage on the Yana River in the Sakha Republic (Yakutia)
Authors: Parfenova O. T.
Published: December 2023

In 2022, Verkhoyansky District of Yakutia experienced the largest flood of the regional scale, affecting 1,220 people and with the cost of emergency recovery work amounting to RUB 160.2 million. For the Arctic regions, the consequences of natural disasters are felt several times more acutely, due to the natural and geographical peculiarities and the duration of the process of restoration of the disturbed ecosystem. Protection of the population and territories of the Arctic is one of the priority tasks of the state policy of Russia. The article assesses the flood hazard on the Yana River. Based on the analysis of historical elevations at hydrological posts, hydrological characteristics of the water body, determination of maximum levels, water discharge of the river, and basic hydrological calculations, the area of flooded territory of settlements in Verkhoyansky District of the Sakha Republic (Yakutia) under the percentage availability is determined, and a map of flood zones is drawn up. Using the cadastral value of lands falling into the flood zone, the index of forecast economic damage is determined in order to preliminarily determine the scale of flooding; to carry out preventive measures for preparation, protection of the population, socially important objects, buildings and structures; to plan the amount of financial resources required for rescue operations and for liquidation of the consequences of emergency situations. A comparison and an analysis of actual and estimated damage indicators are given. A strong disproportion in the actual and calculated indicators of economic damage is proved.

Obesity-related disruptions in female reproduction are a growing concern. The neuroendocrine regulation of female reproduction in the context of obesity involves the intricate interplay between adipokines and the Hypothalamus-Pituitary- Ovarian (HPO ) axis. In this review, we explore the role of adipokines, particularly leptin and adiponectin, in regulating neuroendocrine female reproduction in the context of obesity. Leptin, primarily produced by adipocytes, plays a pivotal role in signaling energy status to the brain. However, excessive levels of obesity can lead to leptin resistance, affecting the HPO axis and causing menstrual irregularities and fertility issues. Adiponectin, on the other hand, is reduced in obesity and influences insulin sensitivity and ovarian function. We delve into the impact of altered adipokine levels on the HPO axis, discussing disruptions in hormone secretion, oocyte maturation, and ovarian steroidogenesis. This study paves the way for further exploration of adipokine-related pathways and potential therapeutic targets, enhancing our understanding of the intricate relationship between obesity and female reproduction.

In recent years, thermally activated delayed fluorescence (TADF) has attracted intense attention owing to its straightforward application to high-efficiency organic light-emitting diodes. Further, to develop high-performance TADF materials, many researchers have designed novel molecules that have a small energy gap between the lowest excited singlet and triplet states (∆E_ST), and detailed analysis suggest a significant contribution of higher lying excited states for spin flipping processes. In this study, we studied the spin-flipping process of the donor–acceptor TADF molecule with 1,3,6,8-tetramethyl-9H-carbazole as the donor unit and 5,9-dioxa-13b-boranaphtho[3,2,1-de]anthracene as the acceptor unit (TMCz-BO) and observed peculiar thermally activated behaviour similar to that of the negative gap molecule HzTFEX2 (a heptazine derivative). By comprehensive kinetic analysis across various temperatures in various solvents, the peculiar thermal behaviour of TMCz-BO can be explained with a normal four-state configuration without a negative small energy gap between the S1 and T1 states. While the activation energy has previously been treated as being temperature independent, we stress that it should be a dynamic parameter affected by the environmental temperature, especially in the case of a small energy gap of ~10 meV. Insufficient analysed results would cause confusion and inhibit the visualization of the true picture of the TADF mechanism. We anticipate that the comprehensive analysis in this study will provide information for the molecular design of advanced TADF emitters in organic light-emitting diodes.
Substituent effects on the equilibria between cyclopropylcarbinyl, bicyclobutonium, homoallyl, and cyclobutyl cations
Authors: Larmore Sean , Champagne Pier Alexandre
Published: December 2023

The cyclopropylcarbinyl (CPC) and bicyclobutonium (BCB) structures of the C4H7+ cation have been proposed as intermediates in various synthetic transformations forming cyclopropylcarbinyl, cyclobutyl, or homoallyl products. It has recently been recognized that such cations, when generated from chiral electrophiles, are themselves chiral and can react with nucleophiles stereospecifically. However, the CPC and BCB cations are in equilibrium with each other and with other related structures such as the cyclobutyl (CB) and homoallyl (HA) cations, from which stereospecificity is not guaranteed. Currently, the effect of substitution on the composition of cation mixtures containing CPC/BCB/CB/HA cations is not understood, precluding the prediction and control of the major products generated from such cations. Using Density Functional Theory and DLPNO-CCSD(T) calculations, we have studied the electronic and steric effects on the equilibria between mono- and polysubstituted C4H7+ cations. Our results indicate that electron-donating groups at the C1 position favor CPC structures, while BCB/CB structures are favored for the C2 position and HA structures for the C3/C4 positions. Electron-withdrawing groups yield shallower potential energy surfaces where many related structures are energetically accessible. Strong Hammett correlations (σ+) are observed for the various substituent effects, which appear to be additive in nature. In addition, BCB cations with more substituents are energetically destabilized compared to CPC cations, except with donating substituents at the C2 position. This work provides a predictive model for the major structures observed in mixtures of CPC/BCB/CB/HA cations, for given substituent patterns.
Implementing the Blowers-Masel Approximation to Scale Activation Energy Based on Reaction Enthalpy in Mean-field Micro-kinetic Modeling for Catalytic Methane Partial Oxidation
Authors: Xu Chao , Mazeau Emily , West Richard
Published: December 2023

Mean-field micro-kinetic modeling is a powerful tool for catalyst design and the simulation of catalytic processes. The reaction enthalpies in a micro-kinetic model often need to be adjusted when changing species’ binding energies to model differ- ent catalysts, when performing thermodynamic sensitivity analyses, and when fitting experimental data. When altering reaction enthalpies, the activation energies should also be reasonably altered, to ensure realistic reaction rates. The Blowers-Masel ap- proximation (BMA) relates the reaction barrier to the reaction enthalpy. Unlike the Brønsted-Evans-Polani (BEP) relationship, the BMA requires less data because only one parameter, the intrinsic activation energy, needs to be determined. We validate this novel application of BMA relations to model surface reactions by comparing against density functional theory (DFT) data taken from literature. By incorporating the BMA rate description into the open-source Cantera software we enable a new work- flow, demonstrated herein, allowing rapid screening of catalysts using linear scaling relationships (LSRs) and BMA kinetics within the process simulation software. For demonstration purposes, a catalyst screening for catalytic methane partial oxidation (CMPO) on 81 hypothetical metals is conducted. We compare the results with and without BMA-corrected rates. The heat maps of various descriptors (e.g. CH4 conver- sion, syngas yield) show that using BMA rates instead of Arrhenius rates (with constant activation energies) changes which metals are most active. Heat maps of sensitivity analyses can help identify which reactions or species are most influential in shaping the descriptor map patterns. Our findings indicate that while using BMA-adjusted rates didn't markedly affect the most sensitive reactions, it did change the most influential species.

Published: December 2023

Two-dimensional metal-organic nanosheets (MONs) have emerged as attractive alternatives to their three-dimensional metal-organic framework (MOF) counterparts for heterogeneous catalysis due to their greater external surface areas and higher accessibility of catalytic active sites. Zr MONs are particularly prized because of their chemical stability and the high Lewis and Brønsted acidities of the Zr clusters. Herein, we show that careful control over modulated self-assembly and exfoliation conditions allows the isolation of the first example of a two-dimensional nanosheet wherein Zr6 clusters are linked by dicarboxylate ligands. The hxl topology MOF, termed GUF-14 (GUF = Glasgow University Framework), can be exfoliated into monolayer thickness hns topology MONs, and acid-induced removal of capping modulator units yields MONs with enhanced catalytic activity towards the formation of imines and the hydrolysis of an organophosphate nerve agent mimic. The discovery of GUF-14 serves as a valuable example of the undiscovered MOF/MON structural diversity extant in established metal-ligand systems that can be accessed by harnessing the power of modulated self-assembly protocols.

This research focused on the determination of potentially toxic elements (PTEs) distribution in different agricultural soils and Ambrosia atremisiifolia L. (ragweed) at seven, different locations in the northern part of Bosnia and Herzegovina (BiH). Quantification of PTEs was done using atomic absorption spectrophotometry provided after acid digestion of the air-dried samples of soil and plant material. Determined content of elements in the soils increased as follows: Cd<Pb<Cu<Zn<Cr<Ni<Mn<Fe and were under the allowed maximum for unpolluted soils, except for Ni and Cr. However, transfer of Ni and Cr from the soil to the ragweed as well as their bioaccumulation was not intensive. Established metal contents ratio from plant tissues (root and shoot) to soil for both elements, represented their bioaccumulation factors (BAF), which were extremely low in the roots, as well as in the shoots, both in average less than 0.2. On the other hand, Zn showed a tendency to accumulate in ragweed shoots (BAF=2.07). The study showed that uptake and accumulation of PTEs in the ragweed was mainly influenced by their content in the soil, as well as specific characteristics and biological role of each element. Hence, content of PTEs in the ragweed tissue could be used as the soil contamination degree indicator.

Soil hydraulic properties play a crucial role in the unsaturated soil water supply process. Currently, Tunisia lacks a database containing essential values for soil retention properties and soil saturated hydraulic conductivity. The main objective of this study is to create the inaugural soil hydraulic properties database through the utilization of open-access data and pedotransfer functions (PTFs). To achieve this goal, the harmonized world soil database (FAO) was employed to identify 752 measurement points across Tunisia. Subsequently, the soil texture, organic carbon content, and bulk density were determined at each point. These acquired values were then entered into the CalcPTF software to estimate the van Genuchten soil retention parameters. The calculation of soil saturated hydraulic conductivity was accomplished using two widely recognized pedotransfer functions (Saxton and Rosetta). The outcomes facilitated the creation of a catalog containing soil hydraulic parameter value for each soil texture. Significance of discrepancies between values obtained from the PTFs was assessed using a Tukey test. The spatial variability of each soil hydraulic property was studied using the simple kriging. In conclusion, the establishment of this significant soil hydraulic properties database holds diverse applications in agricultural, hydrological, and environmental studies in Tunisia.

El desarrollo de la competencia investigativa es una tarea inminente del proceso formativo en la licenciatura en Educación y ello urge hacerlo desde la impartición de las asignaturas de la malla curricular. En la actualidad el proceso formativo transcurre en la educación superior se exige que el proceso de enseñanza – aprendizaje que se lleva utilice las experiencias didáctico-pedagógicas que han predominado de manera positiva en los distintos modelos educativos que se conocen, pero utilizando diferentes alternativas didácticas y se utilizan las tecnologías de la información y las comunicaciones como medios de enseñanza actualmente. Se desarrolló la investigación con enfoque mixto en un grupo de 40 estudiantes del 3er semestre de la licenciatura en Educación. Se determinaron las principales problemáticas presentes en el programa de la materia Pedagogía y Didáctica y en el desempeño académico de los estudiantes, a partir de las cuales se trabajó utilizando elementos de la escuela nueva, bajo los referentes teóricos de la Escuela Histórico – Cultural. En consonancia con  ello, también se realizaron precisiones de los temas para establecer una lógica estructural satisfactoria y congruente con el desarrollo de la competencia investigativa, como exige la carrera, en la que se determinó su sistema de contenidos-habilidades-valores, que permitiera utilizar estrategia de enseñanza-aprendizaje contentivas de la escuela nueva, entre las que se destacó el Aula Invertida, el Método investigativo; la Enseñanza Asistida por Proyectos, entre otras, apoyados en técnicas de estimulación del desarrollo intelectual que potencian el desarrollo del pensamiento crítico y el pensamiento creativo en estudiantes del Campus Caborca, Universidad de Sonora, México.

La educación pública rural del Perú posee dificultades en términos de acceso y calidad, puesto que los estudiantes con una primera lengua distinta al español, como el quechua, no contarían con un adecuado acceso y uso de las Tecnologías de la Información y las Comunicaciones (TIC) para su aprendizaje. Ello porque las TIC y sus aplicativos no están en su lengua materna, dificultando la enseñanza o inclusión de la identidad de los estudiantes. El objetivo de esta investigación fue entender, a través de las perspectivas de los docentes, cuáles eran las barreras lingüísticas a las que se enfrentaban los estudiantes quechua hablantes del área rural del Perú al usar las TIC. Se contó con una metodología de enfoque cualitativo, en el que se empleó entrevistas semiestructuradas a una muestra de 5 docentes que enseñan en quechua en el Perú y que tienen conocimiento acerca de la educación rural del país. Los resultados indicaron que; no todas las TIC y sus aplicativos estaban configurados en quechua y que no todos los estudiantes quechua hablantes reciben tales TIC, el que las TIC y sus aplicativos no estuviesen en quechua generaba frustración en el proceso de aprendizaje de los estudiantes e impidiéndoles fortalecer su identidad, las autoridades cuando elaboraban las TIC y sus aplicativos en quechua, no tomaban en cuenta el contexto de los estudiantes, lo que debería mejorarse mediante una política pública sostenida.

El análisis de la presente investigación planteó como objetivo central determinar la relación entre el empowerment y compromiso organizacional en el personal docente del centro educativo San Francisco de Asís en Huaycán, Lima, 2022. La metodología utilizada para el estudio es de nivel correlacional, bajo el enfoque cuantitativo y de diseño no experimental – transversal. Los datos fueron recolectados a través del cuestionario aplicado a una población establecida por 46 docentes; la confiabilidad de ambos instrumentos se evidenció bajo el estadístico Alpha de Cronbach, empowerment (0.871) y compromiso organizacional (0.782). Se logró como resultado una correlación entre ambas variables dado que el coeficiente estadístico Rho de Spearman refleja valor de 0.585, lo cual  responde a una correlación significativa positiva moderada, del mismo modo se observa que las dimensiones del empowerment influyen de manera directa y positiva con el compromiso organizacional recibiendo valores que corresponden a una correlación positiva; es decir, a más empowerment mayor compromiso organizacional.

Las bacterias fijadoras de nitrógeno y leguminosas mantienen una relación simbiótica, que les permite obtener nutrientes de manera eficiente, sin embargo, existe escasa información de las características morfológicas y medio de conservación adecuado de las bacterias que nodulan en el sistema radical de la variedad rosada de alverja (Pisum sativum L). El objetivo de esta investigación fue aislar y conservar cepas nativas de Rhizobium sp., a partir de los nódulos radicales del cultivo de arveja, variedad rosada, para lo cual se estableció el cultivo de arveja en campo en el cantón Espejo, provincia del Carchi. Para la obtención de los nódulos en campo, se realizó un muestreo aleatorio en zig – zag de plantas jóvenes y vigorosas en la etapa fenológica de floración. Se tomaron 3 plantas en 5 puntos de muestreo, para un total de 15 plantas del lote. Los nódulos obtenidos se llevaron al laboratorio y se sembraron en Levadura Manitol Agar con Azul de Bromotimol (YMA + AB). Se caracterizó morfológicamente las cepas nativas de Rhizobium y se observó colonias de forma circular, convexas con borde entero y superficie lisa, de color blanca cremosa rosada y consistencia gelatinosa y mediante la tinción de Gram, se reportó bacilos Gram negativos, además, se realizó la caracterización bioquímica, donde se identificó la cepa nativa perteneciente al género Rhizobium, por su reacción positiva a la prueba de Biuret, resistencia a NaCl  2%, e incapacidad de producir H2S, características típicas de cepas de rizobio. Además, un elemento esencial en la identificación fue la falta de absorción del colorante rojo congo. Se conservó la cepa aislada en medio YMA + AB, para luego incubar a 30 °C por 5 días y bajo condiciones de asepsia, se llevó la cepa a una nevera a temperatura de 4 °C, para preservar la integridad genética del microorganismo.

En Ecuador, el oso andino (Tremarctos ornatus) está catalogado en peligro de extinción como consecuencia de la afectación de su hábitat por actividades antrópicas. En la Parroquia Plaza Gutiérrez, provincia de Imbabura, se han reportado ataques a cultivos de maíz y ganado vacuno, generando un conflicto humano-oso andino. El objetivo de la investigación fue analizar la percepción de los habitantes afectados por el conflicto oso andino – humano en esta parroquia, con el fin de incorporar esta variable en la construcción de estrategias de mitigación de esta interacción. Se aplicó una encuesta a los 20 pobladores afectados por ataques de oso en la parroquia, visitando y georreferenciando cada predio. La información recabada se socializó entre afectados y actores clave en un taller participativo realizado para construir, consensuadamente, las estrategias de conservación. La presencia del oso en la zona fue ratificada por la totalidad de los afectados, considerándole una especie perjudicial (80%) y calificando la interacción con una intensidad media (75%) a alta (20%). Los daños económicos en el período 2013-2018 se estimaron en 21.055 US$, siendo el maíz el rubro más afectado. La valoración de la especie por parte de la población afectada indicó dos tendencias: la primera fue concebirla como una especie perjudicial, debido a las afectaciones que generan en sus predios. La segunda fue destacar su valor y respeto como ser vivo. Las soluciones propuestas se centraron en promover prácticas de agricultura y ganadería sostenible para reducir los ataques del oso en la parroquia.
