TENDENCIES AND PROBLEMS OF THE ALTERNATION OF ASSESSMENT OF PUPILS’ ACHIEVEMENTS AND PROGRESS IN DIFFERENT STAGES OF LITHUANIAN EDUCATION REFORM
Authors: Vaškelienė Lina , Grabauskienė Antanina
Published: May 2021

With reference to educational documents and articles of scholars and teachers-practitioners, this arti-cle analyzes the tendencies and problems of the alternation of the assessment of pupils’ achievements and progress in primary school in the plane of education reform; the aim is also to reveal the input of Lithuanian scholars and teachers-practitioners on purpose of creating a new system of assessment. The analysis of the stages of education reform demonstrated that all stages emphasize the necessity to democratize pupils’ as-sessment system with a gradual transition towards idiographic assessment and a refusal to assess primary school children with marks. In response to the requirements of the education reform, in 1998–2004 the scholars gave most attention to a theoretical grounding of the assessment of pupils’ progress. In the third stage of Lithuanian education reform (2003–2008) methodical articles prevail which offer various versions of assessment, achievement books, whereas the attention of the scholars towards the system of assessment is decreasing. With reference to this, we make an assumption that the removal of scholars in the third stage of the reform was the main reason for teachers and students to be unsatisfied with the modern system of as-sessment.
Key words: primary education, pupils’ learning achievements, progress, assessment, alternation of the as-sessment.

Cloud computing has drawn expanding interests from both scholastic and industry in the recent years because of its productiveness and low-cost management. Since it offers different types of assistance in an open organization, it is critical for users to utilize secure information for stockpiling and sharing data to guarantee information classification and data users protection. To safely Protect information, the most broadly utilized technique is encryption. The dual-access control, with regards to cloud-based storage, is a control system over both the data owner and the user who can upload and download files without loss of safety, data[1] and effectiveness. The credulous arrangement is that the user can download the whole database[2]. The framework planned in this paper is when the A user logs in with his credentials and after successful acceptance from the two different administrators, the user will be able to download the file present over the cloud. When a malicious user requests, the administrators can find it because it will generate a null value and they can block the user from downloading the files.

Published: May 2021

Cloud Computing is one of the important fields in the current time of technological era. Here, the resources are available virtually for users according to pay-per-usage. Many industries are providing cloud services nowadays as pay for usage which reduces the computing cost drastically. The updated software services, hardware services can be provided to the user at a minimum cost. The target of the industries and scientists is to reduce the computing cost by various technologies. Resource management or task scheduling may also play a positive role in this regard. There are various virtual machine management algorithms available that can be tested and enhanced for research and benefit of the society. In this paper, three famous Max-Min, Ant Colony Optimization, and Particle Swarm Optimization algorithms have been used for experiments. After simulation results, it is found that the PSO algorithm is performing well for makes pan and cost factors. Further, a new algorithm can be proposed or a meta-heuristic technique can be enhanced or modified for getting better results.

Published: May 2021

Since they are isolated in their later years, most people are still forgotten and powerless in medical crises. To deal with this, we've devised a potential Remote Health Monitoring and Warning System (RHMAS). Heart attacks in the elderly are linked with complications such as body temperature changes, elevated blood pressure, profuse sweating, and an abnormal cardiac rhythm, among others. Our approach is to include sophisticated sensors capable of detecting and tracking these signs in order to warn family members, kin, family practitioner, and health care in the event of an emergency. Since most gadgets for this reason are wired, a wireless interface does not obstruct the user's movement. The suggested device includes a Photo-Plethysmography (PPG) dependent pulse sensor to identify arrhythmia, a temperature sensor to continuously track their body temperature, a pressure sensor to sense blood pressure ranges, and a heartbeat sensor. If the controlled data deviates from the nominal body state, an ESP 8266 module can give a message to the next of kin. If the tracked data hits emergency thresholds, health providers can send a message to her kin as well as a buzzer to a consent user.

Beyond intuitions: A biological interpretation of cognition

How can the study of cognition become an ordinary science that is intrinsically connected to the other natural sciences? Since the cognitive revolution in and around psychology, ‘cognition’ has become the standard term to refer to the processes that make us – humans – intelligent. The interpretation of this cognitive domain and cognition itself, however, has never become really clear. First, cognition is a mental concept that is conceptually linked with theories and ideas that are not self-evidently connected to the world as described by the natural sciences. In addition, cognition tends to remain a phenomenon that we recognize ‘on sight’, without the need for an explicit demarcation criterion, a ‘mark of the cognitive’.

In this paper, I abandon this intuition-based demarcation of cognition and propose an unequivocal biological one. This biological demarcation does not build on our current intuitions concerning cognition and in any many cases will not be in line with these. As a consequence, the direct conceptual connection between cognition and the traditional notion of ‘mind’ will be cut and the term ‘cognition’ will acquire a fundamentally different meaning. However, the term ‘cognition’ can and will be maintained, as with its new meaning it still refers to the processes that make us humans – as well as other organisms – intelligent: it still covers the scientific domain that its original form was meant to cover, although now with some additional areas.

The proposal states that cognition is to be interpreted as the interactions between organisms and their environments together with the organismal structures specifically involved in this interaction. This proposal gives a specific material foundation to cognitive phenomena, which can act as the empirical basis for existing and new cognitive theory formation that will place human cognition unequivocally in the wider framework of living organizations.

Some of the implications of the proposal will be further illustrated by differentiating between agents and organisms. When organisms rather than agents form the focal point for cognition, due consideration can be given to ongoing research on intelligence in bacteria, plants and fungi, as well as research concerning the fundamental roles played by nervous systems in animals.

The COVID-19 pandemic, which was first seen in Wuhan, China, caused by the virus named SARS-CoV-2, causes serious, economic and social problems with the deaths of nearly 1.5 million people all over the world. Although initially diagnosed with COVID-19, only mild/moderate cold/flu-like symptoms were seen in the vast majority of cases, COVID-19 results in severe respiratory failure in individuals with advanced age and chronic disease. Because the infection is very contagious, it makes the prognosis of the patients worse by switching to other patients. It plays an important key role in the healthcare team in breaking the nurses’ chain of infection and minimizing disease and treatment-related complications. Therefore, nurses are expected to take precautions to minimize the transmission of COVID-19 and at the same time meet their care needs with a holistic perspective. This situation is only possible with a qualified and holistic nursing care. It is a necessity for patients who have undergone amputation to receive qualified care both physically and mentally in terms of developing a favorable prognosis. Systematized data collection models, internationally accepted nursing diagnoses and interventions should be used in order to provide optimal and standardized nursing care in patient groups where comorbid conditions such as COVID-19 develop with amputation. In this case report, the nursing care of a transtibially amputated COVID-19 patient is presented using the Functional Health Patterns Model (FSO) and the North American Association of Nursing Diagnostics (NANDA) nursing diagnoses. The case in the study included nursing diagnoses that require the care of physiological problems such as hyperthermia, less than necessary nutrition, risk of fluid electrolyte imbalance, disruption in gas exchange, as well as nursing diagnoses aiming to care for emotional problems such as anxiety and body image deterioration. Thus, it was aimed to meet physiological, emotional and social care needs as a requirement of holistic care in nursing philosophy. Positive care outcomes were determined as a result of the holistic nursing care for the patient. Keywords: diabetic foot, amputation, COVID-19, nursing care, functional health patterns
Using material flow cost accounting to determine the impacts of packaging waste costs in alcoholic beverage production in an alcoholic beverage company in Durban
Authors:   , Tajelawi Omolola Ayobamidele
Published: May 2021

A large number of manufacturing companies adopt the use of the traditional accounting method in their operations. This technique fails to reflect a detailed report of all material losses incurred in their production processes. Worthy of note, is that losses/waste are considered as inefficiencies in manufacturing operations and viewed as a costly venture to the sustainability of the company. This research, therefore, through a case study analysis, examined the efficient/inefficient flow of resources in the production process of an alcoholic beverage company in the Durban metropolis. The study was carried out in order to determine the impact of packaging waste cost in an alcoholic beverage company using the material flow cost accounting technique. Measurements included the input of packaging materials against its output, while giving consideration to waste incurred as losses. The Material Flow Cost Accounting (MFCA) technique, an environmental management accounting tool developed for measuring the flows and stocks of materials of a company and production process in both physical and monetary units, was used to measure the costs of waste on two production lines. MFCA was used to trace all material inputs and categorize them as product or non-product output. MFCA is used to classify the relevant material flows as cost collectors, thereby allocating the costs of the company’s production operations and flows. Different packaging materials that constitute waste on the lines were analyzed using the mixed method approach, which includes observation, questionnaire administration, and analysis of six months production report. Two production lines were considered for sampling, and recommendations were given based on the data analyzed using the SPSS package. The MFCA technique revealed that losses on both production lines were understated, and that, the bottling plant was losing a sizeable amount of monetary value of packaging materials to waste. The MFCA technique also revealed that the traditional costing technique is unable to provide adequate information managers require for strategic cost decision making. MFCA is therefore recommended to assist managers improve production line efficiency and cost savings via accurate waste costing and reduction for corporate sustainability.
THE CONCEPT OF IMAGO DEI IN THE THOUGHT OF GERRIT CORNELIS BERKOUWER

Published: May 2021

Gerrit Cornelis Berkouwer was a significant Dutch Reformed theologian. This article will observe Berkouwer’s concept of imago Dei based on systematic-biblical method. In other words, biblical concept will only support the systematic-theological based discussion. It will be demonstrated through this article that, in comparison to previous approaches of explaining the concept of the image, Berkouwer had made a significant contribution. That contribution is found in his emphasis on the functional aspect of being the image. In doing this, on one hand, he followed the path of Reformatory tradition, but on the other hand, he also diverted from the Reformatory tradition on some issues about the concept of the image.

At the end of the 20th century discussions about human freedom has become discussions about free will. Discussions about this topic end up with the polemic between autonomy and heteronomy. The idea of autonomy tries to eliminate all limitations that obstruct human freedom. But after all the limitations have been eliminated, there are some raise questions about internal authority in a person’s self that limits him or her. In the opinion of the writer, theologians who approaches the problem of human freedom as a ‘freedom from’ would never touch the essence of human freedom. Gerrit Cornelis Berkouwer discusses human freedom not with the ‘free from’ approaches that will lead to a secularistic humanism but tries to look at the meaning of freedom biblically, that is “true freedom.” This kind of freedom does not depend on both external nor internal authorities, but rather depend on the hope of eschatological liberation where the believers will be in full obedience to Christ.

Contradições na “Cidade do charme”: a interseccionalidade nas desigualdades em Baltimore, Estados Unidos
Authors: Daniel Camila
Published: May 2021

Este artigo analisa a interseção entre raça, classe e fluxos migratórios no espaço urbano, enfocando no caso de Baltimore, EUA. Cidade majoritariamente negra, Baltimore enfrenta uma segregação racial histórica, agravada pelos ciclos de crise do capitalismo. No final do século XX, a cidade sofreu com a desindustrialização, o desemprego estrutural, uma brusca queda populacional e uma política de austeridade. Na tentativa de recuperar a economia da cidade, Baltimore mergulhou numa reforma urbana que privilegia os bairros majoritariamente brancos, através de empreendimentos corporativos e do investimento em equipamentos de hospedagem, lazer, esporte, turismo e infra-estrutura que deram a Baltimore a alcunha de “cidade do charme”. Enquanto isso, os bairros negros sofrem ou com o desinvestimento ou com a gentrificação. Baseando-me numa análise bibliográfica e no trabalho de campo etnográfico realizado entre 2016 e 2019, concluo que a imigração complexifica as tensões raciais e as desigualdades no espaço urbano.
A un año de la pandemia: Los cuidados en el centro y en los márgenes

Published: May 2021

La pandemia del COVID-19 da cuenta de múltiples crisis (sanitaria, económica, política, de cuidados), todas preexistentes, que colapsan a medida que se prolonga una nueva cotidianeidad y donde poco ha cambiado en términos de responsabilidades sociales. El artículo identifica los principales ejes conceptuales en torno al cuidado y a su reconocimiento como derecho humano, como también el tratamiento del cuidado durante la pandemia y las configuraciones que lo caracterizan, en su mayoría asentadas sobre la asignación de responsabilidades en las mujeres. En base a un abordaje desde el enfoque de género y derechos humanos, se analizan los escenarios que la retórica de la “nueva normalidad” ha introducido, y que llevan a cuestionar el efectivo alcance de las soluciones coyunturales sobre el marco de desigualdades estructurales previas.

Model simulations of chemical effects of sprites in relation with observed HO2 enhancements over sprite-producing thunderstorms
Authors: Winkler Holger , Yamada Takayoshi , Kasai Yasuko , Berger Uwe , Notholt Justus
Published: May 2021

Abstract. Recently, measurements by the Superconducting Submillimeter-Wave
Limb Emission Sounder (SMILES) satellite instrument have been presented
which indicate an increase in mesospheric HO2 above sprite-producing thunderstorms.
The aim of this paper is to compare these observations to model simulations
of chemical sprite effects.
A plasma chemistry model in combination with a vertical transport module
was used to simulate the impact of a streamer discharge in the
altitude range 70–80 km, corresponding to one of the observed sprite events.
Additionally, a horizontal transport and dispersion model was used
to simulate advection and expansion of the sprite air masses.
The model simulations predict a production of hydrogen radicals
mainly due to reactions of proton hydrates formed after the electrical discharge.
The net effect is a conversion of water molecules into H+OH.
This leads to increasing HO2 concentrations a few hours
after the electric breakdown.
Due to the modelled long-lasting increase in HO2 after a sprite
discharge, an accumulation of HO2 produced by several sprites appears
possible.
However, the number of sprites needed to explain the
observed HO2 enhancements is unrealistically large.
At least for the lower measurement tangent heights, the
production mechanism of HO2 predicted by
the model might contribute to the observed enhancements.
Using artificial neural networks to predict riming from Doppler cloud radar observations

Published: May 2021

Abstract. Riming, i.e. the accretion and freezing of SLW on ice particles in mixed-phase clouds, is an important pathway for precipitation formation. Detecting and quantifying riming using ground-based cloud radar observations is of great interest, however, approaches based on measurements of the mean Doppler velocity (MDV) are unfeasible in convective and orographically influenced cloud systems. Here, we show how artificial neural networks (ANNs) can be used to predict riming using ground-based zenith-pointing cloud radar variables as input features. ANNs are a versatile means to extract relations from labeled data sets, which contain input features along with the expected target values. Training data are extracted from a data set acquired during winter 2014 in Finland, containing both Ka-band cloud radar and in-situ observations of snowfall. We focus on two configurations of input variables: ANN #1 uses the equivalent radar reflectivity factor (Ze), MDV, the width from left to right edge of the spectrum above the noise floor (spectrum edge width; SEW), and the skewness as input features. ANN #2 only uses Ze, SEW and skewness. The application of these two ANN configurations to case studies from different data sets demonstrates that both are able to predict strong riming (riming index = 1) and yield low values (riming index ≤ 0.4) for unrimed snow. In general, the predictions of ANN #1 and ANN #2 are very similar, advocating the capability to predict riming without the use of MDV. It is demonstrated that both ANN setups are able to generalize to W-band radar data. The predictions of both ANNs for a wintertime convective cloud fit coinciding in-situ observations extremely well, suggesting the possibility to predict riming even within convective systems. Application of ANN #2 to an orographic case yields high riming index values coinciding with observations of solid graupel particles at the ground.

Abstract. Layers of biomass burning aerosol particles were observed in the lower troposphere, at 2 to 5 km height on 4 to 6 June 2019, over Kuopio, Finland. These long-range-transported smoke particles originated from a Canadian wildfire event. The most pronounced smoke plume detected on 5 June was intensively investigated. Optical properties were retrieved from the multi-wavelength Raman polarization lidar PollyXT. Particle linear depolarization ratios of this plume were measured to be 0.08 ± 0.02 at 355 nm and 0.05 ± 0.01 at 532 nm which were slightly higher than the values given in the literature. Non-spherical shaped aged smoke particles and/or the mixing with a small amount of fine dust particles could cause the observed increase in the particle linear depolarization ratios. Lidar ratios were derived as 47 ± 5 sr at 355 nm and 71 ± 5 sr at 532 nm. A complete ceilometer data processing for a Vaisala CL51 is presented, including the water vapor correction for high latitude for the first time, from sensor provided attenuated backscatter coefficient to particle mass concentration. A combined lidar and sun-photometer approach (based on AERONET products) is applied for mass concentration estimations. Mass concentrations were estimated from both PollyXT and the ceilometer CL51 observations, which were of the order of ~ 30 µg m−3 in the morning and decreased to ~ 20 µg m−3 in the night. A difference of ~ 30% was found between PollyXT and CL51 estimated mass concentrations. The mass retrievals were discussed and compared with the Modern-Era Retrospective analysis for Research and Applications, version 2 (MERRA-2) meteorological and aerosol reanalysis. The inclusion of dust in the retrieved mass concentration slightly improved the correspondence between the observations and the MERRA-2 simulations.
LES study of precipitation/condensation dependance on cumulus clouds dynamics
Authors: Kogan Yefim L.
Published: May 2021

Abstract. Parameters affecting condensation/evaporation rates (CR/ER) in trade wind cumulus
clouds were analyzed using LES model simulations. The model was initialized
with data observed during the RICO field project, and simulated in a rather
large 50.0×50.0×4 km3 domain. 2031 clouds were
analyzed seeking relationships between CR/ER and thermo-dynamical cloud
parameters. The condensation/evaporation rates were analyzed by stratifying
the clouds by their size. The analyzed parameters included, among others,
integral mass and buoyancy fluxes, as well as cloud and rain water and drop
concentration. The results revealed rather remarkable relationship between integral
condensation/evaporation rate and integral upward mass flux. Identified
relathionship may be useful for parameterization of subgrid latent heat in
meso and large-scale models.
Theoretical insights from upscaling Michaelis-Menten microbial dynamics in biogeochemical models: a dimensionless approach
Authors: Wilson Chris H. , Gerber Stefan
Published: May 2021

Abstract. Leading an effective response to the accelerating crisis of anthropogenic climate change will require improved understanding of global carbon cycling. A critical source of uncertainty in Earth Systems Models (ESMs) is the role of microbes in mediating both the formation and decomposition of soil organic matter, and hence in determining patterns of CO2 efflux. Traditionally, ESMs model carbon turnover as a first order process impacted primarily by abiotic factors, whereas contemporary biogeochemical models often explicitly represent the microbial biomass and enzyme pools as the active agents of decomposition. However, the combination of non-linear microbial kinetics and ecological heterogeneity across space guarantees that upscaled dyamics will violate mean-field assumptions via Jensen’s Inequality. Violations of mean-field assumptions mean that parameter estimates from models fit to upscaled data (e.g. eddy covariance towers) are likely systematically biased. Here we present a generic mathematical analysis of upscaling michaelis-menten kinetics under heterogeneity, and provide solutions in dimensionless form. We illustrate how our dimensionless form facilitates qualitative insight into the significance of this scale transition, and argue that it will facilitate cross site intercomparisons of flux data. We also identify the critical terms that need to be constrained in order to unbias parameter estimates.
A wavelet-based approach to streamflow event identification and modeled timing error evaluation
Authors: Towler Erin , McCreight James L.
Published: May 2021

Abstract. Streamflow timing errors (in the units of time) are rarely explicitly
evaluated but are useful for model evaluation and development. Wavelet-based approaches have been shown to reliably quantify timing errors
in streamflow simulations but have not been applied in a systematic way
that is suitable for model evaluation. This paper provides a step-by-step
methodology that objectively identifies events, and then estimates timing
errors for those events, in a way that can be applied to large-sample,
high-resolution predictions. Step 1 applies the wavelet transform to the
observations and uses statistical significance to identify observed events. Step 2 utilizes the cross-wavelet transform to calculate the timing errors for the events identified in step 1; this includes the diagnostic of model event hits, and timing errors are only assessed for hits. The
methodology is illustrated using real and simulated stream discharge data
from several locations to highlight key method features. The method groups
event timing errors by dominant timescales, which can be used to identify
the potential processes contributing to the timing errors and the associated model development needs. For instance, timing errors that are associated with the diurnal melt cycle are identified. The method is also useful for documenting and evaluating model performance in terms of defined standards. This is illustrated by showing the version-over-version performance of the National Water Model (NWM) in terms of timing errors.

Abstract. In 2018 Typhoon Mangkhut (locally known as Typhoon Ompong) triggered thousands of landslides in the Itogon region of the Philippines. A landslide inventory of the affected region is compiled for the first time, comprising 1101 landslides over a 570 km2 area. The inventory is used to study the geomorphological characteristics and land cover more prone to landsliding as well as the hydrometeorological conditions that led to widespread failure. The results showed that landslides mostly occurred on grassland and wooded slopes of clay superficial geology, predominantly facing east-southeast. Rainfall (Integrated Multi-satellitE Retrievals for Global Precipitation Measurement, IMERG GPM) associated with Typhoon Mangkhut is compared with 33 high-intensity rainfall events that did not trigger regional landslide events in 2018. Results show that landslides occurred during high-intensity rainfall that coincided with the highest soil moisture values (estimated clays saturation point), according to Soil Moisture Active Passive level 4 (SMAP-L4) data. Our results demonstrate the potential of SMAP-L4 and GPM IMERG data for landslide hazard assessment and early warning where ground-based data are scarce. However, other rainfall events in the months leading up to Typhoon Mangkhut that had similar or higher rainfall intensities and also occurred when soils were saturated did not trigger widespread landsliding, highlighting the need for further research into the conditions that trigger landslides in typhoons.

BORIS TISHCHENKO. THE TWELVE. CREATION HISTORY AND BASIC COMPOSING PRINCIPLES
Authors: Serov Yuri
Published: May 2021

The article is devoted to the history of the creation and music score of the ballet Twelve based on the poem by A. Blok by the outstanding Russian composer of the second half of the twentieth century Boris Ivanovich Tishchenko. The ballet was staged by the famous Soviet choreographer Leonid Jacobson back in 1964 and became, in fact, the first avant-garde ballet in the Soviet Union. Critics noted Tishchenko’s bright modern symphonic music and Jacobson’s free plastics, which “became a breath of clean air in the rarefied atmosphere of classical epigonism”.

COLD FUSION ON THE BASIS OF THE MODEL OF THE PLANET EARTH
Authors: Tarassenko G.V. , Tarassenko M.G.
Published: May 2021

Cold fusion is not possible in atmospheric conditions but it is possible underground. Synthesis formation is connected with electricity in the entrails of the earth. Electricity is produced with the help of friction and geospheres speed differential from the core (20-40 m/s to the surface), the speed of which according to GPS data is 2-16 cm per year. Faraday has determined planet electric capacity with 1 farad. Continent drift takes place at the expense of geospheres rotation, leading to subduction of ocean and continental plates, abduction, spreading, rifting and collision. An example of planet formation is ball concretions.

Authors: Nori Mauricia , Scoponi Liliana , Durán Regina , Fernandes Pacheco Dias Marcelo
Published: May 2021

La trazabilidad se ha difundido en diferentes países para garantizar una oferta de productos con buenas condiciones higiénico-sanitarias y nutricionales, empleándose en sistemas de certificación de calidad y gestión de las cadenas agroalimentarias. En la Argentina, los avances con este alcance son aún insuficientes en la cadena de la carne bovina. Se analizan, así, las presiones coercitivas, normativas y cognitivas sobre trazabilidad y su influencia en la gestión de la ganadería del Sudoeste bonaerense, actividad clave para el desarrollo local y nacional, mediante una investigación cualitativa a partir de documentos y entrevistas semiestructuradas. Se concluye que la Argentina ha avanzado en regulaciones sobre identificación animal para control sanitario y fiscal, sin una implementación holística y con visión comercial del sistema. Varios factores inciden para que las presiones normativas y cognitivas sean débiles en pos del aseguramiento de la calidad, como políticas de exportación, complejidad de las disposiciones y asimetrías del mercado interno.
Prácticas de Buen Gobierno Corporativo en empresas argentinas
Authors: Corzo Lilia José
Published: May 2021

Las prácticas de buen gobierno corporativo toman relevancia en las empresas de países emergentes, caracterizados por marcos institucionales deficientes y bajo desarrollo de sus mercados financieros. Este trabajo evalúa las prácticas de gobierno corporativo de empresas de capital abierto de la República Argentina a partir de dos índices académicos: Internet based corporate disclosure index (Garay et al, 2013) y el Índice de Transparencia en Gobierno Corporativo (Briano Turrent, 2012). La aplicación de ambos tiene por objeto poder comparar si una empresa con más transparencia informativa (medido como la transferencia de información vía web de la empresa) también tiene mejores prácticas de gobierno corporativo. De acuerdo a los resultados encontrados, solo en el caso de una de las empresas analizadas se verificó esta relación. En general, las empresas argentinas se remiten al cumplimiento de las normativas vigentes en materia de gobierno corporativo, sin realizar mayores esfuerzos en sus prácticas de transparencia informacional.
