De víctimas a pedagogas de la memoria: el caso de las llamadas Madres de Soacha
Authors: Gutiérrez Carlos Arturo
Published: September 2021

En 2008, unos jóvenes desaparecieron de Soacha, un municipio aledaño a Bogotá. Meses después sus cuerpos aparecieron en el departamento de Norte de Santander, donde fueron presentados por el ejército colombiano como guerrilleros dados de baja en combate. La lucha que sus madres llevaron a cabo para esclarecer lo sucedido dio lugar a una organización defensora de derechos humanos conocida como las Madres de Soacha. Tras los hechos, otras mujeres, que no eran propiamente de Soacha y cuyos familiares fueron asesinados bajo la misma modalidad, pero en años y lugares diferentes, se articularon con ellas, tejieron vínculos con organizaciones defensoras de derechos humanos y actualmente adelantan una batalla contra el olvido. De esta manera han dado visibilidad a este acontecimiento que tenía un espacio de escucha limitado y que aún es negado por ciertos sectores.

Abstract: In 2008, a group of young men disappeared from Soacha, a commune adjoining to Bogotá. Months later, their bodies were found in Norte de Santander, where they were presented by Colombian army as guerrilla soldiers killed in combat. The battle that their mothers started to enlighten what happened resulted in a human rights defender organization known as Madres de Soacha. After those events, other women, which were not exactly from Soacha, and whose relatives were killed the same way, but in different years and places, weaved links with those women, and human rights defenders organizations. Nowadays, all these women are fighting against oblivion, giving visibility to facts that had a very limited listening space and are still denied by some sectors.

Keywords: falsos positivos, Mothers of Soacha, official memories, disturbing memories.

Contrarrestando reclamos de democracia. El poder de las narrativas y la disputa por la jurisdicción en sectores extractivos en Colombia
Authors: Dietz Kristina
Published: September 2021

El artículo está enfocado en el uso de narrativas para entender la manera como los reclamos de participación democrática en los conflictos por minería y extracción petrolera están siendo contrarrestados por actores del Estado y de las corporaciones. Teóricamente, el análisis está basado en una interpretación dialéctica entre narrativas y agencia, en la que las narrativas son entendidas como productos contingentes de interacción social. Se argumenta que para impedir la institucionalización de la participación democrática y evitar un cambio en las relaciones de poder en el sector minero y petrolero, se usa una combinación de diversas narrativas. Las narrativas principales son adaptadas a los reclamos de opositores, complementadas con nuevas historias en reacción a las condiciones cambiantes del contexto y combinadas para diferentes contextos, escenarios y públicos. Empíricamente, el estudio se enfoca en las disputas en torno a consultas populares por minería, fracking (fracturación hidráulica) y explotación de petróleo en Colombia. Los datos de análisis consisten en entrevistas semiestructuradas; transcripciones de dos audiencias públicas transmitidas en directo, una en el Senado de la República y otra en la Corte Constitucional; y varios artículos de dos de los principales periódicos colombianos: El Tiempo y El Espectador. El periodo investigado cubre desde junio de 2013 hasta noviembre de 2018.

Counteracting Claims for Democracy. The Power of Narratives and the Dispute over Jurisdiction in Extractive Sectors in Colombia

Abstract: The article focuses on the use of narratives to understand how demands for democratic participation in mining an oil extraction conflicts are being countered by state and corporations. Theoretically, the analysis is based on a dialectical interpretation about narratives and agency, in which narratives are understood as contingent products of social interaction. It is argued that to prevent the institutionalization of democratic participation and prevent a change in power relations in the mining and oil sector, a combination of diverse narratives is used. The main narratives are adapted to the claims of opponents, complemented by new stories in reaction to the changing conditions of the context and combined for different contexts, scenarios and audiences. Empirically, the study focuses on disputes over popular consultations about mining, fracking (hydraulic fracturing) and oil exploitation in Colombia. The data analyzed came from semi-structured interviews, from transcripts of two public hearings transmitted live, one in the Senate of the Republic and one in the Constitutional Court, and from several articles from two of the main Colombian newspapers: El Tiempo and El Espectador. The period under investigation covers from June of 2013 to November of 2018.

Naturvitenskapelige praksiser og tenkemåter – på vei mot et tolkningsfellesskap
Authors: Haug Berit S. , Sørborg Øystein , Mork Sonja M. , Frøyland Merethe
Published: September 2021

Scientific practices are introduced in curricula around the world, replacing the more general concept of inquiry. There are many different definitions of scientific practices, and the purpose of this article is to contribute to a common understanding of what scientific practices are and how they can be implemented and assessed in the classroom. We analyzed the Norwegian curriculum LK20 and found that teachers are mainly left on their own in how to interpret, implement and assess scientific practices. To address the lack of support, we selected a set of central scientific practices based on LK20, the research literature and international curricula and described the practices as explicit and close to teaching practice as possible. Implications for use are discussed, together with a call for other researchers to join the discussion.
WHAT IS NEW IN CARDIOVASCULAR MEDICINE?
Authors: Mesihović-Dinarević Senka
Published: September 2021

The rapid pace of change continues to be a hallmark in cardiovascular medicine and many see that pace accelerating in adult cardiovascular medicine as well as in paediatric cardiology medicine. Cardiovascular medicine is an area of clinical practice with a continually rapid expansion of knowledge, guidelines, best practices and new technology. Cardiovascular diseases are the leading cause of mortality in the world and cause major costs for the health sector and economy. Primary care clinicians are challenged to optimally manage a multitude of diseases including congestive heart failure, coronary artery disease, valvular diseases, arrhythmias, lipid disorders, and hypertension. Multimodality imaging techniques are being used more frequently as their utility is better appreciated. Echocardiography has been the mainstay approach, cardiac computerized tomography and magnetic resonance imaging provide a good imaging alternative for patients with multiple complex surgeries. 3D printing has seen a rapid growth in use for planning treatments for patients with congenital heart disease. Simulation using 3D models is emerging as a fundamental resource for teaching procedural techniques and a new standard of care. Artificial intelligence holds the greatest potential for revolutionizing medicine. Innovative technologies in the world of cardiovascular health are expanding every day: wearable computing technologies, bioresorbable stents, leadless pacemaker, valve-in-valve procedure, protein patch for heart muscle growth and others. As a part of lifelong learning process for all professionals in cardiovascular medicine, the imperative is to have continuity of reviewing novelties, with results data from numerous researches in order to treat patient according to best practices and evidence-based medicine.

Similarity searches can be modeled by means of distances following the Metric Spaces Theory and constitute a fast and explainable query mechanism behind content-based image retrieval (CBIR) tasks. However, classical distance-based queries, e.g., Range and k-Nearest Neighbors, may be unsuitable for exploring large datasets because the retrieved elements are often similar among themselves. Although similarity searching is enriched with the imposition of rules to foster result diversification, the fine-tuning of the diversity query is still an open issue, which is is usually carried out with and a non-optimal expensive computational inspection. This paper introduces J-EDA, a practical workbench implemented in Java that supports the tuning of similarity and diversity search parameters by enabling the automatic and parallel exploration of multiple search settings regarding a user-posed content-based image retrieval task. J-EDA implements a wide variety of classical and diversity-driven search queries, as well as many CBIR settings such as feature extractors for images, distance functions, and relevance feedback techniques. Accordingly, users can define multiple query settings and inspect their performances for spotting the most suitable parameterization for a content-based image retrieval problem at hand. The workbench reports the experimental performances with several internal and external evaluation metrics such as P × R and Mean Average Precision (mAP), which are calculated towards either incremental or batch procedures performed with or without human interaction.
Criminal Responsibility For Non-Risky Behaviors
Authors: Antolak Wiktor
Published: September 2021

The category of abstract-danger crimes not referring in hallmarks to the riskiness for legal good raises the question whether behavior formally fulfilling all the features of one of these types of crimes, without being risky, may be the subject of criminal liability. This question arises from the fact that there is no logically necessary relationship between the compliance with this kind of statutory description and the real occurrence of the riskiness. The answer to this question is sought in this paper by using normative analysis conducted in the context of human rights and of the constitution. This method makes it possible to understand the significance of the relation between behaviors and legal goods for the legitimization of a legal norm. So, the method shows what kind of the relation constitutes the state's competence to prohibit certain behaviors (the level of a sanctioned norm) and what character the relation must have to justify imposing a criminal penalty for given behaviors (the level of the sanctioning norm). These considerations, having a specific and pragmatic aim, which is to settle whether the behaviors realizing all hallmarks of the abstract dangerous type of crime but atypically non-risky could be a factual basis for criminal repression, at the same time show the limits of criminal law because they allow seeing what the conditions are that constitute the state's competence to use penal repression.
Wohin steuern die Ultra-vires- und die Identitätskontrolle? Eine Zwischenbilanz anhand der Entscheidungen des Bundesverfassungsgerichts im PSPP-Verfahren
Authors: Walter Christian
Published: September 2021

The article takes stock of the consequences which the decisions of the German Federal Constitutional Court (FCC) concerning the Public Sector Purchase Programme (PSPP) of the European Union (EU) have had on the relation between EU law and the German constitution. The interplay between the PSPP judgment of 5 May 2020 and a follow-up decision on its enforcement reveals a certain degree of back-paddling by the FCC. Irrespective of the infringement procedure, which the European Commission recently initiated against Germany, there are good chances for a respite for both the FCC and the Court of Justice of the EU. It is up to the FCC to use this period to clarify where it is headed with its jurisprudence on controlling the application of EU law in Germany.

This article scrutinizes the impact of the widely criticized PSPP-judgement of the Federal Constitutional Court (FCC) on the Union´s legal order. It shows that the European Commission´s opening of an infringement procedure was inevitable due to the FCC´s disregard of the rules of the preliminary reference procedure, denies the necessity of a modification of the Union´s judicial architecture and develops recommendations for the future loyal cooperation between the FCC and the Court of Justice of the European Union (CJEU) in handling such disputes.
A Paradigm Change: The CETA Investment Chapter
Authors: Bungenberg Marc , Reinisch August
Published: September 2021

The Investment Chapter of the Comprehensive Economic and Trade Agreement (CETA) can be seen as an unofficial blueprint of future EU Investment Agreements and Chapters. It was developed under immense public pressure and had to fulfil multiple conditions resulting from the EU constitutional framework. This contribution highlights the political and juridical background of EU investment policy, and then analyses the most significant new approaches in international investment law - both with regard to substantive standards and investor-State dispute settlement - as exemplified in the CETA. With regard to the substance, it can be witnessed that states are more proactive in defining investment protection standards, leaving less discretion for adjudicators. With regard to dispute settlement, the EU managed to introduce a completely new Investment Court System (ICS) with preselected adjudicators and an appellate mechanism. In light of all these developments, this article argues that we are currently facing a complete change of paradigms in EU investment law, heading towards the EU’s long-term goal of establishing a Multilateral Investment Court (MIC).
Concentrations in the Aviation Sector: How to maintain the level playing field for airlines and airports?
Authors: Lemonnier Valentine
Published: September 2021

Before the Covid-19 pandemic hit, the scheduled passenger air transport sector was already subject to several horizontal concentrations. The mix of free competition and strict regularization in the air transport sector in the EU raises the question whether the current framework will still be able to provide a level playing field to the market participants, notably airlines and airports. The study focusses on how EU competition law has influenced horizontal concentrations (i.e. mergers and horizontal co-operations) in the scheduled passenger air transport sector. The results of the discussion are the basis for a reflection of the effects of different types of horizontal concentrations on the negotiation power of airlines vis-à-vis airports. A third focus of the study is the identification of regulatory weaknesses with regard to airport financing under the Airport Charges Directive (Directive 2009/12/EC), how those weaknesses benefit airlines and how they might interfere with efforts made under the application of competition law.
Nanosilver in Biomedicine: Advantages and Restrictions
Authors: V. Morozova Olga , V. Klinov Dmitry
Published: September 2021

Nanosilver (in a range 1–100 nm) binds with thyol-, amino- and carboxy-groups of aminoacid residues of proteins and nucleic acids, thus providing inactivation of pathogenic multidrug-resistant microorganisms. Besides antibacterial, antiviral, antifungal and anti-cancer properties Ag-based nanomaterials possess anti-inflammatory, anti-angiogenesis and antiplatelet features. Drug efficacy depends on their stability, toxicity and host immune response. Citrate coated Ag nanoparticles (NPs) remain stable colloid solutions in deionized water but not in the presence of ions due to replacement of Ag+ by electrolyte ions, potential formation of insoluble AgCl, subsequent catalyzed oxidative corrosion of Ag and further dissolution of surface layer of Ag2O. Protein shells protect core of AgNPs from oxidation, dissolution, aggregation and provide specific interactions with ligands. These nanoconjugates can be used for immunoassays and diagnostics but the sensitivity threshold does not exceed 10 pg Cytotoxicity of AgNPs conjugated with proteins is associated with the rate of intracellular Ag+ release, a ‘Trojan horse’ effect, and exceeds one of Ag+ because of endocytosis uptake of NPs but not ions. Relatively toxic nanosilver causes immunosuppression of the majority of cytokines with a few exceptions (IL-1β, G-CSF, MCP-1) whereas AgNO3 additionally activate TNFα and IL8 gene expression.

Authors: Nakisa Nima , Ghasemzadeh Rahbardar Mahboobeh
Published: September 2021

Rheumatoid arthritis (RA) is a chronic inflammatory and debilitating joint disorder that causes severe impairment and reduces the quality of life. The available synthetic medicines used as standard therapy for RA have numerous side effects that can compromise their therapeutic outcomes. Thus, the demand for alternative and complementary medicines is increasing. A search of English articles in PubMed, Scopus, Google Scholar, and Web of Science databases was carried out on probable mechanisms of action of herbs with the antirheumatic property. Herbal medicines stated in folk medicine face acceptance concerns by the medical community because of the lack of scientific documents regarding their physio-pharmacological mechanisms. This chapter aims to review the possible antirheumatic effects of various herbs, including Rosmarinus officinalis L., Curcuma longa, and Crocus sativus, their related mechanisms, and preclinical applications, in order to recall the therapeutic properties of herbal medicine. However, more clinical trials are required to confirm the safety and efficacy of these antirheumatic herbal medicines.

The authors believe that this chapter will be a valuable tool for all healthcare providers (students, physicians, and in nursing care) in managing this challenging condition.
Drosophila Central Taste Circuits in Health and Obesity
Authors: Kaushik Shivam , Rawat Shivangi , Kain Pinky
Published: September 2021

When there is a perturbation in the balance between hunger and satiety, food intake gets mis-regulated leading to excessive or insufficient eating. In humans, abnormal nutrient consumption causes metabolic conditions like obesity, diabetes, and eating disorders affecting overall health. Despite this burden on society, we currently lack enough knowledge about the neuronal circuits that regulate appetite and taste perception. How specific taste neuronal circuits influence feeding behaviours is still an under explored area in neurobiology. The taste information present at the periphery must be processed by the central circuits for the final behavioural output. Identification and understanding of central neural circuitry regulating taste behaviour and its modulation by physiological changes with regard to internal state is required to understand the neural basis of taste preference. Simple invertebrate model organisms like Drosophila melanogaster can sense the same taste stimuli as mammals. Availability of powerful molecular and genetic tool kit and well characterized peripheral gustatory system with a vast array of behavioural, calcium imaging, molecular and electrophysiological approaches make Drosophila an attractive system to investigate and understand taste wiring and processing in the brain. By exploiting the gustatory system of the flies, this chapter will shed light on the current understanding of central neural taste structures that influence feeding choices. The compiled information would help us better understand how central taste neurons convey taste information to higher brain centers and guide feeding behaviours like acceptance or rejection of food to better combat disease state caused by abnormal consumption of food.
Hemodynamic Perspectives in Anemia
Authors: Ravikumar Nakul , R. Sheinfeld Geoffrey , T. McGee William
Published: September 2021

Oxygen delivery in normal physiologic states is determined by cardiac output, hemoglobin, oxygen saturation, and to a lesser extent, dissolved oxygen in the blood. Compensatory mechanisms such as an increase in stroke volume, heart rate, and re-distribution of blood flow helps in scenarios with increased oxygen demand. In cases of acute hemodynamic decompensation, this pre-existing physiologic relation between oxygen delivery and oxygen consumption is altered, resulting in tissue hypoxia and resultant anaerobic metabolism. A persistent state of sub-critical O2 delivery correlates with increased mortality. Oxygen consumption itself is usually independent of delivery unless a critical threshold is unmet. We can use various parameters such as serum lactate, oxygen extraction, and central venous oxygen saturation to determine this pathology. A basic understanding of this physiology will help better tailor therapy to improve outcomes in critically ill patients.

Published: September 2021

Context: Coronavirus disease 2019 (COVID-19) has been one of the deadliest pandemics in recent decade. The virus has specifically targeted the comorbid population in terms of mortality. The present systematic review and meta-analysis aimed to determine the overall mortality and diabetes-associated mortality in COVID-19 patients. Methods: To obtain the related data, six databases, including Pubmed, Embase, MEDLINE, Web of Science, Google Scholar, and DOAJ, were searched. The full-texts of articles presenting the data of COVID-19 mortality and diabetes-associated mortality were screened and retrieved. Statistical analysis was performed using the Stata (version 13). The odds ratio (OR) of mortality in diabetic patients was calculated with 95% confidence interval (CI). Random-effects model was used to synthesize data for the relevant outcomes. Heterogeneity was evaluated using I2 statistic. Forest plots visually showed the effect estimates of the included studies. We used funnel plots to evaluate potential publication bias. A two tailed P < 0.05 was considered as statistically significant. Results: A total of 35 studies with 25,934 patients were finally included for meta-analysis. The pooled prevalence of diabetes mellitus in patients with COVID-19 was 16.8% (n = 4381). The overall mortality seen in all the studies was 12.81% (n = 3159), and diabetes-associated mortality was 22.14% (n = 970). The pooled analysis of included studies showed that diabetes mellitus had a significantly higher mortality rate (22.14% vs. 12.81%, P < 0.05) with higher odds of death (pooled OR 1.83, 95% CI: 1.61 - 2.05). The funnel plot was symmetric, thereby indicating a low risk of publication bias. Conclusions: In conclusion, the presence of diabetes was associated with a significantly increased risk of mortality in patients admitted to the hospital with COVID-19. Thus, this subpopulation must be continuously monitored for glycemic levels, coagulation abnormalities, and inflammatory surge.

Published: September 2021

: Health clinics are significant destinations for the creation of risky waste. Every clinic has its own profile for the management and transport of waste contingent upon its area. It is amazingly crucial to guarantee that the waste created in medical clinics is sufficiently kept away from dangers to well-being and the climate. The manuscript describes the control of clinical waste, which incorporates infectious waste, synthetic substances, lapsed medications, radioactive trash, and rough waste are the major ones in hospitals. On the off chance that the administration is not efficient, it becomes perilous, as they are pathogenic and environmentally unsafe. Inability to do so can bring about negative results; for example, genuine well-being chances and the clinic's standing. This article portrays the different ways to deal with the powerful administration of clinic squander. The authors conclude that pretreatment is basic before discarding emergency clinic squander in a hospital to minimize hazardous issues.

Background: One of the complications of cesarean section (C/S) is related to the incision site. Considering the effectiveness of platelet–rich plasma (PRP) on healing of wounds and management of scars, the present study aimed to inquire the effect of PRP on the thickness and completeness of the uterine scar. Methods: In a randomized double-blinded, placebo-controlled clinical trial, the women who underwent C/S from November 2019 to 2020 were included and randomized into two studied groups, including the control (n = 15) and intervention (n = 15) groups. In the intervention group, PRP, extracted from patients’ blood samples, was injected to the incision site (between decidua and myometrium), while the control group did not receive this treatment. The scar thickness of C/S as the primary outcome and postpartum hemorrhage as the secondary outcome were compared between the groups. Both groups were followed for 12 weeks. Results: The two groups (intervention and control) were not significantly different in terms of weight, height, BMI, age, parity, gravidity, duration of surgery, and blood hemoglobin (HB) level (P > 0.05). Comparison of scar characteristics showed the creation of a niche in the PRP group, which was almost one-fourth of that of the control group; a difference that was statistically significant (P = 0.002). The thickness of adjoining myometrium was comparable between the two groups. Mean uterine niche height in the intervention group was lower than in the control group, which was statistically significant (P = 0.048). The mean of residual myometrium thickness (RMT) in the intervention and control groups were 7.62 ± 0.95 and 5.6 ± 3.5 mm, respectively, a difference that was statistically significant (P < 0.001). Conclusions: Local injection of PRP is an effective and viable measure for reducing the uterine niche; therefore, it is suggested to be included in the routine wound care of CS. Future studies are needed to confirm PRP efficacy in different settings.

Published: September 2021

The state economic development is largely determined by the effectiveness of its individual structural elements. Among them, a special place is occupied by trends in the mineral sector, which dictates the requirements and mechanisms for the development of natural resources, creating the basis for a national strategy. However in this area there are a number of unsolved problems, which include: a low level of rational use of machine-technological mining systems from under the water with minimal man-made impact. The authors consider existing and alternative extraction methods of peat raw materials. The tasks facing the mineral resource sector can be solved through technological priority developments of aggregated extraction complexes for the peat raw materials and the equipment modernization for mining complexes. The analysis is carried out and recommendations are made for the working equipment modernization of the aggregated mining complex. Variants of the excavator excavation bucket for the extraction of peat raw materials from under water have been proposed. The results of studies on primary dehydration, combining mining and dewatering cycles in a bucket, are presented; the work gives the recommendations on the bucket use and the expediency of operating the mining machine's extraction body when extracting peat raw materials.
A Model for Prediction of the Buffalo and Cattle male Calves' live Weight
Authors: Soliman Ibrahim
Published: September 2021

The buffalo and cattle population in Egypt reached about 4.898,893 and 3,476,396 heads, respectively, in 2019. The buffalo and cattle meat production represented around 43% and 45% of the total meat production in Egypt, respectively, and the average carcass weight of buffalo and cattle reached 318 kg and 336Kg in 2019. About 50% of livestock numbers are slaughtered off-slaughter houses due to a shortage in the capacity of slaughterhouses and other financial and administrative reasons. The conducted field survey of this study showed that the majority of Egyptian livestock markets lack live weight scales, and if available, they are expensive and frightening for the animals. Therefore, numerous feedlot enterprises hire an agent who can visually forecast the expected live weight of the exhibited feeder calves for sale in the market at a high charge. Most of the models to predict the weight of live cattle-bulls knowing the chest circumference were lacking such models for buffalo-bulls and were linear models that fit only limited periods of cattle-fattening. The sample survey included 500 buffalo males and 340 cattle males of different live weights from 14 villages in 4 provinces in the Nile Delta. The data were used to estimate the best-fitted model for Egyptian livestock. This study showed that the best-fitted model was curved linear. It was a quadratic form. For empirical application, the study designed a table to predict the live weight of buffalo and cattle males at a range of 100-200 cm chest circumference. The results showed that a 1% increase in the chest circumference was associated with a 2.4% and 2.8% increase in the buffalo and cattle male's circumference, which implicitly reflects higher live weight gain of cattle than buffalo males and better meat quality. Therefore, the farm price of cattle feeder males surpassed the buffalo by $1000.
The influence of aromatic amino acids on the chemical composition of mint plants genus (Mentha L.)
Authors: Velička Aloyzas , Tarasevičienė Živilė , Danilčenko Honorata
Published: September 2021

The aromatic amino acids, tryptophan, phenylalanine and tyrosine, are not only components of proteins, but also precursors of many compounds in plants that have a significant impact on their growth, development, reproduction and protective function against various abiotic and biotic factors. With the growing demand for plant-derived chemical compounds, much in vitro and in vivo research is being conducted to intensify the synthesis of these compounds or to change their qualitative composition in plants. The aim of the research was to evaluate the influence of aromatic amino acids on the chemical composition of different varieties of Mentha L. plants. The field experiment was conducted at Aleksandras Stulginskis University (ASU) in 2017–2019, since 2019 at the Vytautas Magnus University Agricultural Academy Experimental Station, which is located in Ringaudai Eldership, Kaunas District (coordinates 54 ° 53′ 08.9″ N, 23° 50′ 08.02″ E). The effect of different concentrations of amino acid solutions on the chemical composition of mints depended on the mint variety. Spraying with all amino acids solutions significantly increased the dry matter, crude fiber and crude ash content in M. spicata ‘Crispa’ mints while a positive effect of amino acids solutions on the protein content was found only in M. piperita ‘Granada’ mints sprayed only with 200 mg l–1 tyrosine solution, where the amount of protein increased significantly by 1.41-fold compared to that of non-sprayed plants. The intensity of the synthesis of photosynthetic pigments depended on the amino acid solutions used and the variety of mint. There were both inhibitory and stimulatory effects.

Published: September 2021

The aim of this work was to investigate and compare the amounts of biologically active compounds, dry matter and soluble solids in pulp and peels of four pear cultivars (‘Ksena’, ‘Beloruskaja pozdniaja’, ‘Alna’ and ‘Aleksandr Lucas’). The research was carried out at Vytautas Magnus University Agriculture Academy (Lithuania) in 2020. Four pear cultivars (‘Ksena’, ‘Beloruskaja pozdniaja’, ‘Alna’ and ‘Aleksandr Lucas’) were cultivated at a farm in the Joniškis District of Lithuania. Pears were grown following traditional pear production technology. The amounts of dry matter, soluble solids, vitamin C and fiber were determined using the standard method. The total content of phenolic compounds was determined using a Folin-Ciocalteu reagent with a UV/VIS spectrophotometer. The research results showed that significantly the highest amounts of soluble solids were found in the ‘Alna’ pear fruit pulp (14.25% f. w.). The ‘Alna’ peel sample had significantly the highest amount of total phenolic compounds (1290.99 mg 100 g–1 d. w.). The highest content of dry matter was found in the ‘Aleksandr Lucas’ pear fruit peel (24.67%). The ‘Aleksandr Lucas’ and ‘Beloruskaja pozdniaja’ pear fruit peel contained significantly the highest amounts of vitamin C (2.70 and 2.63 mg 100 g–1 f. w., respectively). The highest content of fiber was found in the ‘Ksena’ fruit peel (36.12% d. w.).

O presente artigo examina a volatilidade dos retornos semanais dos preços do etanol hidratado por meio do modelo de variância condicional, também chamado heteroscedástico. A análise compreende o período de 29 de novembro de 2002 a 20 de novembro de 2020. Os resultados empíricos demonstraram as reações de persistência e assimetria na variância dos respectivos retornos, ou seja, boas e más notícias impactam diferentemente sobre a volatilidade dos retornos de acordo com o modelo ARMA(1,1)- APARCH (1,1), com distribuição generalizada de erro, do ponto de vista da realização de previsões.

Para compreender o nível de qualidade de vida de um indivíduo, faz-se necessário conhecê-lo em sua totalidade, avaliando fatores internos e externos que atuam sobre o sujeito. Neste sentido, a variável trabalho exerce grande influência, pois em alguns casos relaciona-se intrinsicamente com a identidade do ser, como ocorre no trabalho docente. Este estudo observacional, descritivo, de corte transversal e abordagem quantitativa, teve como objetivo identificar o nível de qualidade de vida de docentes de diferentes modalidades de ensino. A amostra foi composta por 79 professores de uma instituição de ensino superior privada localizada em Valença/RJ que responderam a um questionário composto por duas partes: caracterização dos respondentes e identificação do nível de qualidade de vida, este obtido por meio do instrumento genérico de avaliação da qualidade de vida SF-36, dividido em oito domínios. Para análise dos dados, utilizou-se a estatística descritiva, com determinação de frequência, média e desvio padrão e os resultados apresentados por meio de gráficos e tabelas. Observou-se que os docentes que atuam na modalidade presencial e EaD possuem os domínios Capacidade Funcional, Limitações por Aspectos Físicos, Dor, Estado Geral de Saúde e Vitalidade com médias superiores àqueles que lecionam exclusivamente na modalidade presencial, os quais, por sua vez, apresentaram os fatores Aspectos Sociais, Limitações por Aspectos Emocionais e Saúde Mental com valores de médias superiores quando comparado os dois grupos. Diante dos resultados, a instituição deve desenvolver e aplicar ações que potencializem a qualidade de vida desses profissionais.

A maior velocidade em satisfazer as necessidades e desejos dos consumidores fazem com que um bom gerenciamento de estoques seja essencial para alcançar vantagem competitiva. A gestão de materiais é importante para a boa performance organizacional, pois permite a utilização mais eficiente dos recursos cada vez mais escassos. O objetivo do presente estudo é analisar e propor um plano de gerenciamento de estoques em uma empresa de fornecimento de materiais odonto-médico-hospitalares na cidade de Vitória da Conquista/BA. Foi realizado um levantamento dos produtos adquiridos e custos administrativos/operacionais, entre junho de 2020 e dezembro de 2020. Ainda assim, houve a  realização de entrevista  semi estruturada com o gestor. Como resultado, foi constatado que a empresa realizava a gestão dos estoques com base no senso comum e houve compras equivocadas, falta e excesso de materiais. Produtos odonto-médico-hospitalares possuem alto custo de aquisição e manutenção. Estoques elevados como forma de diminuir o risco de falta de materiais foi nocivo para a organização. A principal contribuição deste estudo é voltada para a área gerencial com implicações práticas, a partir da aplicação de ferramentas de gestão de estoque como estoque mínimo, estoque máximo, lote econômico de compra, ponto de pedido e curva ABC. Tais ferramentas auxiliam na minimização de riscos operacionais.

Com a democratização do acesso ao ensino superior houve uma expansão significativa no número de cursos e vagas em instituições federais do ensino superior. Porém, as mesmas políticas que têm contribuído para essa expansão, não têm sido eficazes em dar condições para a permanência dos estudantes até a conclusão do seu curso. É preciso conhecer as características desses novos estudantes que estão ingressando nessas instituições, principalmente nas localizadas nos interiores, onde ocorreu a maior parte dessa expansão. Diante disso, o presente estudo tem por objetivo analisar as principais diferenças entre os alunos ingressantes no curso de engenharia civil do Campus A.C. Simões e do Campus do Sertão, da Universidade Federal de Alagoas — UFAL entre os anos de 2014 a 2018. Quanto à metodologia, o estudo encontra-se classificado de acordo com os procedimentos como bibliográfica, documental e estudo de caso, e de acordo com os objetivos como descritiva, com uma abordagem quantitativa. Os dados foram coletados em bancos de dados disponibilizados em meio eletrônico e processados utilizando um software estatístico. A partir das análises, verificou-se que os dois grupos possuem características semelhantes no que diz respeito ao perfil básico, porém quanto ao perfil acadêmico, o campus do interior possui índices inferiores em relação ao campus da capital.

A Empresa estatal Brasileira de Correios e Telégrafos, presente em todos os municípios do país, passa por dificuldades por conta de déficits, ineficiência na prestação de serviços e escândalos sobre corrupção e, por isso, tem-se discutido sobre a possibilidade de privatizá-la. Diante disso, o presente estudo, visa, a partir de uma revisão bibliográfica sistematizada, organizar os argumentos favoráveis e contrários à privatização dos serviços postais brasileiros, utilizando-se a análise de conteúdo. Dos 11 (onze) artigos que responderam de forma satisfatória ao problema de pesquisa, observou-se, como argumentos favoráveis à privatização: a diminuição do tráfego postal, o déficit financeiro, o fomento à concorrência com abertura para o mercado internacional com melhorias nos produtos e serviços, greves constantes e exemplos positivos de outras privatizações. Já os autores que se posicionam contra a privatização dos Correios apresentam os seguintes argumentos: o monopólio postal subsidia o custo do serviço em áreas não rentáveis, a ECT é lucrativa, os Correios possibilitam o controle de operações de segurança nacional, haverá redução de postos de trabalho, o monopólio é assegurado por normas jurídicas constitucionais, a privatização não gera diminuição do déficit público, há relevância cultural e histórica em manter o monopólio e houve experiências de outros países em que foi possível notar que nenhum país com dimensões parecidas com as do Brasil optou por privatizar totalmente seus serviços postais, apenas países pequenos o fizeram. Após a análise das categorias, concluiu-se que a privatização não é a melhor opção para o setor postal, mas a abertura de seu capital é uma opção a ser considerada para melhorar seus processos e alavancar seus resultados, mantendo o acesso universal aos serviços de logística oferecidos pelos Correios, sobretudo para as áreas mais carentes.
