Authors: Zanchi Fabrício Berton , Carvalho Ana Luísa Santos de , Da Cruz Raiane Silva , Silva Leonilton Cagy , Pereira Rafael Magalhães
Published: March 2021

Os crescentes desafios quanto ao gerenciamento dos resíduos sólidos (RS) nos municípios e a necessidade da diminuição dos impactos ambientais causados ao meio ambiente vêm impulsionando a busca por estratégias que proporcionem soluções de tais problemas. Dentre estas estratégias está a utilização da modelagem dinâmica de sistemas, que possibilita analisar o comportamento de situações como a geração dos RS em um dado período de tempo. Considerando a necessidade de estudos que corroborem para efetividade na gestão dos RS, este estudo propôs um modelo dinâmico para estimar a geração dos RS e uma rotina para calcular o retorno financeiro dos resíduos reciclados. O modelo foi construído no software STELLA e considerou aspectos como a taxa do incremento populacional, geração de RS per capita diária, bem como, as rotinas de estimativas é composta e identificada pela caracterização gravimétrica e valor praticado na venda dos resíduos que possam ser reciclados. O modelo associa e estimulam as discussões relacionadas com a modelagem dinâmica dos RS, promovendo o desenvolvimento do pensamento teórico e da interação do que é produzido atualmente e o quanto poderá ser produzido futuramente, o que traz a luz para uma melhor estratégia de gerenciamento a ser empregada.

Published: March 2021

As comunidades tradicionais do Baixo Amazonas no Pará possuem diversas atividades pesqueiras que geram emprego e renda para os pescadores. Uma dessas é a pesca do camarão-da-amazônia Macrobrachium amazonicum praticada às margens do rio Amazonas, próximo à cidade de Santarém (PA). Este trabalho tem como objetivo registrar a ictiofauna acompanhante da pesca do camarão-da-amazônia, bem como sua relação com a biomassa total, riqueza, captura por unidade de esforço (CPUE) e a proporção de peixes e camarões. Os dados foram coletados por meio do acompanhamento mensal em três armadilhas semi-fixas na área de pesca no período de fevereiro/2018 a janeiro/2019. As informações foram anotadas e organizadas em um banco de dados para facilitar as análises. Foram capturados um total de 2.136 peixes, com ocorrência de 24 famílias e 69 espécies, sendo Colomesus asellus mais abundante e Hypoptopoma elongatum com ocorrência em todos os meses. O comprimento total foi baixo e variou entre 32 e 275 mm, sugerindo a participação de muitas espécies de pequeno porte e/ou indivíduos juvenis, com pouco ou sem valor comercial. A proporção de peixe/camarão foi de 0,02/35,24 kg indicando que 97% da produção pesqueira do camarão é constituída da espécie alvo, contudo, os peixes jovens são descartados geralmente mortos, impactando negativamente seu ciclo. A diversidade e equitabilidade variaram ao longo dos meses, apontando um padrão de distribuição sazonal relacionado ao regime hidrológico da região.

Vivemos um contexto de estresse hídrico decorrente do modelo econômico hegemônico responsável por uma crise ambiental planetária sem precedentes, que vem causando a devastação dos ecossistemas e o desequilíbrio ecológico. Tal quadro pode ser constatado na Bacia Hidrográfica do rio Urussanga, Sul de Santa Catarina, onde atividades econômicas, como a mineração de carvão, promoveram severa degradação ambiental, contaminando solo, água e ar. Trata-se da bacia catarinense de menor área, porém com passivos ambientais ainda sem intervenção. Diante desse cenário, o presente trabalho buscou analisar as dinâmicas de poder determinantes na apropriação dos recursos hídricos nesse território.  Para tanto, realizou-se pesquisa de abordagem qualitativa, nas modalidades bibliográfica, documental, de campo e estudo de caso, utilizando-se instrumento de análise com enfoque na apropriação de recursos comuns.  Como resultados, constatou-se sobreposição de poder do setor econômico em relação ao interesse coletivo, como na gestão da água, cuja atuação de um setor alinha-se aos segmentos políticos, identificando-se fatores que evidenciam assimetria nos espaços de tomada de decisão. Nesse contexto, o carbonífero se destaca, utilizando estratégias como financiamento de campanhas políticas para se manter, mesmo diante de indicadores de insustentabilidade. Concomitantemente, os instrumentos legais de tutela da água mostram-se insuficientes para evitar a sua poluição.

Published: March 2021

This study explicates the effect of green supply chain management on corporate sustainability performance in Indonesia. We conducted an online survey to collect data from targeted respondents with three years of experience on average in the supply chain management field. The respondents consist of company managers, public accountants, public sector accounting managers, and accounting lecturers. We analyzed the data by implementing ordinary least square regression procedures. Our study results suggest that green purchasing, green manufacturing, and internal environmental management can hardly improve economic performance, social performance, and environmental performance. However, strong evidence shows that green distribution triggers a positive effect on economic, social, and environmental performance. Our study implicates that both private sector companies and public sector organizations in Indonesia, as an emerging country, should consider green supply chain management as a necessity. More organizations should pay more attention to apply the green supply chain framework to nourish the competitive advantage.
Improvement of an Escherichia coli whole-cell biocatalyst for geranyl glucoside production using directed evolution
Authors: Ruediger Julian , Schwab Wilfried
Published: March 2021

The biotechnological production of glycosides is an economically
competitive manufacturing alternative to classical chemical synthesis.
Through continuous production improvement, glycosides can now be used in
low-cost products by various industries. However, many production
systems still suffer from low yields. Directed evolution, coupled with a
suitable screening method, can tackle this challenge. We generated
glycosyltransferase mutants through error-prone-PCR and screened the
library using a small-scale whole-cell biotransformation system. The
screening of only 176 colonies yielded three putative candidates.
Detailed investigations revealed that the reason for the increase in
product titer was mainly due to different expression effects of the
mutagenized genes rather than improved enzyme kinetics. In total, a
60-fold increase in product formation was achieved. Therefore, in
addition to the quality of the mutant library, an efficient and stable
expression system is crucial to achieve high concentrations of active
enzyme and product, as formation of inclusion bodies and other inactive
forms of the biocatalyst reduces productivity.

Proposed Ionizing Radiation Doses of 3711 Fluoroscopy-Guided Epidural Injections
Authors: Sacaklidir Rekib , Ozturk Ekim Can , Sencan Savas , Gunduz Osman Hakan
Published: March 2021

Background: Since fluoroscopy-guided interventional therapies grew
significantly in recent years, exposure to ionizing radiation (IR)
either for patient or medical staff became a critical issue. IR exposure
varies according to the physicians’ experience, patients’ body mass
index (BMI), imaging techniques and type of the procedure performed. The
purpose of this study is to calculate the reference IR doses for
fluoroscopy-guided epidural injections per procedure and BMI to provide
reference doses for potential use in future dose reduction strategies.
Methods: A retrospectively, evaluation of patients who received epidural
steroid injections between January 2015 and December 2020 in a
university hospital interventional pain management center, was
performed. This observational study was conducted with patients aged 
18 who underwent 3711 epidural injections including cervical
interlaminar, lumbar interlaminar, lumbar transforaminal and caudal
approaches. Provided IR doses for each patient were also divided by
patients’ BMI to obtain dose per BMI. Results: The highest IR dose per
procedure was found in caudal epidural injection with 0.218 mGy m2 and
lowest dose was in cervical interlaminar epidural injection with 0.057
mGy m2. The IR dose per procedure was 0.123 mGy m2 for lumbar
transforaminal and 0.191 mGy m2 for lumbar interlaminar epidural
injection. Caudal epidural injection had also the highest IR dose per
BMI which was 0.00749 and cervical interlaminar epidural injection had
the lowest radiation dose per BMI which was 0.00214. Conclusions: We
proposed reference IR dose levels of four approaches of epidural
injections obtained from 3711 injections performed in a university
hospital pain medicine clinic. BMI of patients were taken into account
with the dose levels of injections given per BMI. Multicenter research
with standardized techniques will assure more reliable reference levels
which will guide pain physicians to self-assess their own levels of
radiation exposure.

Authors: Fitriani Novi , Koesrindartoto Deddy Priatmodjo
Published: March 2021

XYZ is a university with the best reputation in Indonesia which has 12 companies engaged in consulting services (construction and non-construction)). The proportion of ownership in this business varies from 20% to 99.99%. This business has several companies that are inefficient and unhealthy because operating costs are greater than revenue. In addition, in 2019, this consulting company experienced a decrease in revenue by 7.11% while the cost of goods sold increased by 7.45%. This study aims to select which companies have good and healthy performance, create new and effective business strategies for the best performing companies, and develop sustainable business and new competitive advantages. This research methodology is qualitative using secondary data in the form of annual financial reports from 12 companies for 2015-2019, websites and other information media. External analysis in this study using macroeconomics, PEST, Porter's Five Forces, and Benchmark Analysis. While the internal analysis uses Financial Ratio Analysis and Altman-Z Score. The tools used to obtain business solutions and strategies from the XYZ consulting firm case are Business Level Formulations, Business Level Strategies, Functional Strategies, and Implementation Strategies. One of the strategies that the author applies in this case is by implementing an acquisition strategy

After analyzing and calculating using the Financial Ratio and Altman-Z Score of 12 companies, the result shows that there are only 7 companies that have good and healthy performance so that they are included in the "safe zone" category with a discriminant zone Z> 2.99. The acquisition strategy was created by combining these companies. The first step is to evaluate each company, then calculate the acquisition to find out the synergy value of the acquisition to compare the value when the acquisition was made and what was not. The calculation results show that the company's FCFF accumulation after the next 10 years on 2030, In the event of an acquisition is IDR 124,131,871,981.11. Meanwhile, if there is no acquisition is IDR 117,285,044,723.00. So that we know there have added value of the synergy IDR 6,846,827,258.11.

Published: March 2021

The colour of the fish skin is one of the important factors to determine the freshness of a fish. There are potential to use the fish images as an alternative to determining the fish freshness. However, the freshness relationship of the fish skin image to the Red, Green, Blue (RGB) colour channel needs to be elucidated to achieve an accurate interpretation of fish freshness. The objective of this study is to determine the freshness of the fish samples using QIM assessment and to extract the RGB colour value from fish skin images. Finally, to establish the relationship between the QIM scores ranging from 1 (fresh) to 3 (spoiled) and RGB value for freshness indicator using fish images. The effects of temperature, environment, and storage method have been shown to play an important role in determining the rate of deterioration towards the quality and freshness level in fish. From this study, a freshness indicator based on the Quality Index Method (QIM) and RGB value for Queenfish and Threadfin were created. Based on the QIM score, Threadfin was easier to deteriorate as compared to Queenfish from its leaner body type properties. Different fish would reflect different freshness reading as Threadfin is in a fresh state when it possesses a QIM score of 1 with RGB values to range between of 143 to 172. As deterioration progresses, the QIM score is at 3 and the RGB values are ranging from 132 to 161. While Queenfish is found to be in a fresh state when it acquires QIM score of 1 and the RGB values are in the range of 148 to 170. It starts to spoil when the QIM score is at 3 and the RGB values are ranging from 154 to 184.

Uno de los campos de las ciencias sociales que concibió históricamente a la tecnología como una herramienta crucial para el progreso y la transformación de las sociedades es la Economía. Desde esta visión autores como Machlup, Bell, Masuda, Castells y Schwab explicaron las transformaciones sociales a partir de la segunda mitad del siglo XX hasta la actualidad mediante la relación economía-tecnología. Desde esta perspectiva la producción de conocimiento es entendida como una actividad económica derivada de la capacidad de la sociedad de crear tecnologías aplicadas al desarrollo social.
Inimputables en contextos penitenciarios argentinos
Authors: Rojas Machado Mercedes
Published: March 2021

En el presente artículo me propongo analizar la situación de personas declaradas inimputables en su vinculación con el Estado desde una lectura de Giorgio Agamben, haciendo hincapié en la forma de ejercicio de poder que predomina en las sociedades occidentales. El eje analítico esta conformado por la relación entre biopolítica, el estado de excepción y la nuda vida que propuesta por el autor, la forma en la que la ley incorpora la posibilidad de disponer de ciertas vidas, en términos de prescindibles o eliminables, a través de la figura de la excepción. Posibilidad que puede ejercerse de forma temporal o permanente sobre un tipo de población en particular, en este caso, infractores de la ley penal declarados insanos. Expongo cómo, desde su enunciación, el sistema de medidas de seguridad curativas para inimputables opera como un conjunto de dispositivos penales que regulan, administran y aplican las medidas previstas para sujetos de una reclusión penal excepcional a la pena privativa de la libertad, debido a sus condiciones particulares. Desde un lenguaje de excepcionalidad en su relación con el Estado, estas personas quedan reducidas a la incertidumbre de su mera existencia física y producidas como nudas vidas, colocándolos en el umbral en donde vida y derecho se confunden.

Published: March 2021

Con el presente informe me propongo socializar mi tesis doctoral defendida en marzo del año 2019 en el marco del Doctorado en Estudios Sociales de América Latina del Centro de Estudios Avanzados de la Universidad Nacional de Córdoba. Presento una síntesis de los principales componentes de la investigación, con el fin de contribuir a la comunidad de las Ciencias Sociales y al colectivo de trabajadoras del servicio doméstico, visibilizando las particularidades de la actividad en una provincia del norte argentino. La estructura sigue la lógica de la tesis, comenzando por el planteo del problema, seguido por el marco teórico-metodológico que permitió abordar el objeto de estudio, los principales resultados, analizados desde un abordaje cuantitativo y cualitativo, y las reflexiones finales.

Se observan múltiples desigualdades hacia el interior del mercado de trabajo santiagueño, con altas tasas de informalidad y precariedad, sumado a las inequidades de género. El servicio doméstico se presenta como la principal actividad entre las mujeres que trabajan, constituido principalmente por trabajadoras provenientes de sectores populares urbanos, cuyas trayectorias laborales son intermitentes e inestables. Las relaciones al interior de la actividad giran en torno a la autoridad de las familias empleadoras, quienes determinan unilateralmente las condiciones de trabajo.

Revealed Comparative Advantage Method for Solving Multicriteria Decision-making Problems
Authors: Gogodze Joseph
Published: March 2021

This study proposes and analyzes a new method for the post-Pareto analysis of multicriteria decision-making (MCDM) problems: the revealed comparative advantage (RCA) assessment method. An interesting feature of the suggested method is that it uses the solution to a special eigenvalue problem and can be considered an analog/modification in the MCDM context of well-known ranking methods including the authority-hub method, PageRank method, and so on, which have been successfully applied to such fields as economics, bibliometrics, web search design, and so on. For illustrative purposes, this study discusses a particular MCDM problem to demonstrate the practicality of the method. The theoretical considerations and conducted calculations reveal that the RCA assessment method is self-consistent and easily implementable. Moreover, comparisons with well-known tools of an MCDM analysis shows that the results obtained using this method are appropriate and competitive. An important particularity of the RCA assessment method is that it can be useful for decision-makers in the case in which no decision-making authority is available or when the relative importance of various criteria has not been preliminarily evaluated.
Are University Rankings Statistically Significant? A Comparison among Chinese Universities and with the USA
Authors: Leydesdorff Loet , Wagner Caroline S. , Zhang Lin
Published: March 2021

Purpose

Building on Leydesdorff, Bornmann, and Mingers (2019), we elaborate the differences between Tsinghua and Zhejiang University as an empirical example. We address the question of whether differences are statistically significant in the rankings of Chinese universities. We propose methods for measuring statistical significance among different universities within or among countries.

Design/methodology/approach

Based on z-testing and overlapping confidence intervals, and using data about 205 Chinese universities included in the Leiden Rankings 2020, we argue that three main groups of Chinese research universities can be distinguished (low, middle, and high).

Findings

When the sample of 205 Chinese universities is merged with the 197 US universities included in Leiden Rankings 2020, the results similarly indicate three main groups: low, middle, and high. Using this data (Leiden Rankings and Web of Science), the z-scores of the Chinese universities are significantly below those of the US universities albeit with some overlap.

Research limitations

We show empirically that differences in ranking may be due to changes in the data, the models, or the modeling effects on the data. The scientometric groupings are not always stable when we use different methods.

Practical implications

Differences among universities can be tested for their statistical significance. The statistics relativize the values of decimals in the rankings. One can operate with a scheme of low/middle/high in policy debates and leave the more fine-grained rankings of individual universities to operational management and local settings.

Originality/value

In the discussion about the rankings of universities, the question of whether differences are statistically significant, has, in our opinion, insufficiently been addressed in research evaluations.
Microbiological safety of food of animal origin from organic farms
Authors: Sosnowski Maciej , Osek Jacek
Published: March 2021

The organic food sector and consumer interest in organic products are growing continuously. The safety and quality of such products must be at least equal to those of conventional equivalents, but attaining the same standards requires overcoming a particular problem identified in organic food production systems: the occurrence of bacterial pathogens such as Salmonella, Campylobacter, Listeria monocytogenes, Staphylococcus aureus and pathogenic Escherichia coli. These food-borne microorganisms were detected in the production environments of such food. The prevalence of pathogenic bacteria in organic livestock and products may be higher, but may also be the same as or lower than in like material from conventional farms. Furthermore, the incidence of antimicrobial-resistant bacteria was more often detected in conventional than in organic production. The aim of this review was to present the recent information on the microbiological safety of food of animal origin produced from raw materials from organic farms.
Peak Plantar Pressure as a Risk Factor for Lower Extremity Overuse Injury Among Infantry Soldiers
Authors: Ņesteroviča Darja , Stepens Ainārs , Vaivads Normunds
Published: March 2021

The majority of reported injuries among military populations are injuries due to cumulative repetitive microtrauma — overuse injuries. Plantar pressure measurement is a simple tool to analyse lower limb biomechanics through the assessment of forces applied to the foot. This study aimed to determine the relation between peak plantar pressure and lower extremity overuse. Sixty-six active-duty infantry male soldiers, with mean age 29.7 years (range 22–40 years), and mean service time 5.2 years (range 1–15 years) participated. The highest peak plantar pressure (PPP) at the forefoot occurred at the hallux (cases: 50.82 n/cm2, SD = 38.84; control: 34.39 n/cm2, SD= 28.03) and 3rd metatarsal head (cases: 54.40 n/cm2, SD = 33.83; control: 49.16 n/cm2, SD=28.87). The study demonstrated elevated PPP among cases. Statistically significant results were found at the hallux (χ2(1) = 6.8; p = 0.01), medial heel (χ2(1) = 5.18; p = 0.02) and lateral heel (χ2(1) = 12.12; p < 0.01) regions. The results show that plantar pressure assessment could be used as a useful screening tool for early lower extremity overuse injury detection.

Published: March 2021

The following study is aimed at investigating the construct validity of the 25-item Connor-Davidson Resilience Scale (CD-RISC 25) on a Romanian military population. The exploratory factor analysis was conducted on 434 male military participants, aged between 24 and 50 years (M = 34.83, S.D. = 6.14) and the confirmatory factor analysis was conducted on a sample of 679 military participants, of 605 men and 74 women, aged between 18 and 59 years (M = 38.37, S.D. = 9.07). Factor analysis of the scale showed it to be a bidimensional, rather than a multidimensional instrument, as the original five-factor structure was not replicated in this military Romanian sample. Moreover, EFAs suggested that a 14-item bidimensional model should be retained and CFA confirmed that this model fit the data best.
Sustainable Maritime Fleet Management in the Context of Global Sulphur Cap 2020
Authors: Atari Sina
Published: March 2021

Since the implementation of Emission Control Areas (ECA) in 2015, investment decisions related to abatement technologies represent a crucial task in the maritime industry. Currently, the focus in the maritime sector is on Sulphur reductions due to SECA regulations and the legislative of Global Sulphur Cap that started in 2020. A special challenge appears in maritime fleet management where sets of ships have to be considered, representing portfolios of assets that have to be equipped with a variety of different options of abatement technologies.

Modern portfolio theory has been applied to various economic decisions to achieve an optimal allocation of resources among different investment opportunities. The research investigates and discusses the application of the Markowitz´ optimization in the context of SECA regulations for maritime fleets. The optimal investment portfolios are taking into account the three most important compliance options based on the use of low Sulphur fuel, the use of LNG fuel and the use of HFO with a scrubber. The theoretical results are empirically validated by a case of a shipping line operating 10 vessels.

Problemy z moralnością zwierząt
Authors: Waleszczyński Andrzej
Published: March 2021

Problems with animal morality: The paper aims at discussing the category of animal morality in the light of contemporary scientific findings and theories. First, the issue of moral development is reconsidered in the context of evolutionary anthropology and primatology, then the main positions in this debate are presented. The author proposes a typology which is based on a distinction between various senses of morality, namely a descriptive, neutral, and normative sense (i.e. evaluative). These three aspects of morality are explained in detail and used when analyzing the problems specific to animal morality. The idea of morality applied by the leading participants of ongoing debates is also discussed. The article concludes with an observation that the main problem of these debates is not the very definition of morality and, at the same time, answering the question as to whether animals (individual species) are moral beings or not, but rather what is essentially problematic are the consequences to be implied from a specific understanding of morality.

Published: March 2021

Red chili plants are one of the important vegetable commodities and have high economic value in Indonesia, most of them are used for household and industrial purposes. The demand for red chili plants is increasing every year so that efforts are needed to increase the productivity of red chili plants. The objectives of study to determine (1) the effect of the interaction between the application of organic fertilizers and inorganic fertilizers on the growth and yield of red chili plants, (2) the effect of the type of organic fertilizer and the correct dosage of inorganic fertilizers on the growth and yield of red chili plants. The research was conducted from January to May 2019 in Sumani village, X Koto Singkarak sub District, Solok District with a height of ± 400 meters above sea level. The design was used a factorial design in a Randomized Block Design (RBD) with 2 factors. The first factor is the use of organic fertilizers derived from cow manure (A1) and straw compost (A2). The second factor is the use of SP-36 fertilizer as a source of phosphate at a dose of 10 g/plant (B1), a dose of 30 g/plant (B2), and a dose of 50 g/plant (B3), each treatment consisting of four sample plants. Data from the observations were carried out by analysis of variance, if the obtained F count was greater than F table 5% followed by a further test of Duncan New Multiple Range Test (DNMRT) at the 5% real level. Parameters were observed: plant height, stem diameter, number of fruits, fruit length, fruit weight per plant, and yield of chili per hectare. The results showed that: (1) The results showed that the application of organic fertilizers was better for the growth and yield of Lotanbar chili plants. (2) The provision of cow manure can increase the growth of plant height, fruit length, fruit weight per plant and plant yield per hectare (3) There is no interaction between types of organic fertilizers and the dosage of phosphate fertilizers.
Heterogeneidade linguística na descrição e ensino de línguas em Moçambique
Authors: Saguate Artinesio Widnesse
Published: March 2021

Constitui objetivo deste ensaio demonstrar como a descrição das línguas em África, concretamente em Moçambique, deve priorizar e tratar de forma crítica a heterogeneidade da língua e a heterogeneidade entre línguas. Para tal, tomo como exemplos: (i) a situação linguística em Moçambique, caracterizada por um contato entre línguas, particularmente entre o português e as línguas nacionais, de origem bantu; (ii) a situação do ensino do português em Moçambique; (iii) e a situação da educação bilíngue em Moçambique. Com base em Labov (1972) e Bakhtin (1992), abordo aspectos de língua, contato linguístico e dialogismo; e considero duas constatações essenciais: (i) a heterogeneidade linguística em Moçambique se manifesta como constitutiva na relação entre o português e as línguas nacionais; (ii) na heterogeneidade entre o português e as línguas nacionais, é, essencialmente, em línguas nacionais o lugar de enunciação dos falantes moçambicanos. Desse modo, defendo a ideia de que, para que um professor de português da educação bilíngue em Moçambique seja capaz de lecionar suas aulas e possa (re)conhecer as nuances que os alunos apresentam nessa língua em sala de aula e, por conseguinte, seja capaz de intervir com competência, é imprescendível o (re)conhecimento da estrutura e do funcionamento, ao mesmo tempo, do português e das línguas nacionais; e esse (re)conhecimento só é possível a partir da descrição dessas línguas.

Published: March 2021

Objetivo: Identificar impactos da pandemia no consumo de bebidas alcoólicas pelos estudantes de medicina de uma faculdade particular da capital de Minas Gerais. Métodos: Estudo transversal, quantitativo, realizado através do questionário AUDIT, com amostra de estudantes matriculados na faculdade particular de medicina em questão no primeiro semestre de 2020. Para a busca científica da escrita do artigo, foram usados artigos publicados nos últimos cinco anos, em Português, Inglês e Espanhol, nas bases de dados Pubmed, Scielo e Lilacs. Resultados: Apesar da constatação de consumo de risco, foi encontrado redução do padrão de consumo e das consequências relacionadas ao uso abusivo da substância durante o período de isolamento. Conclusão: Os desdobramentos da pandemia como a diminuição do convívio social impactaram na redução do consumo de álcool. Apesar dos resultados, como os estudantes de medicina fazem parte deste cenário que potencializa vulnerabilidades e danos psicológicos, intervenções precoces para os casos de consumo de risco encontrados são consideradas importantes para prevenção e promoção de saúde.
Different progression pattern between acral and nonacral melanoma: A retrospective, comparative, clinicoprognostic study of 492 cases of primary cutaneous melanoma according to tumor site
Authors: Jung Joon Min , Jung Chang Jin , Won Chong Hyun , Chang Sung Eun , Lee Mi Woo , Choi Jee Ho , Lee Woo Jin
Published: March 2021

Background:

There are limited data regarding the difference in progression pattern between acral melanoma and nonacral melanoma.

Aims:

The objectives of this study were to compare the progression pattern between acral and nonacral melanoma and evaluate its impact on clinical outcomes.

Methods:

Clinical and histopathological features, survival outcomes and prognostic factors of 492 patients with acral melanoma or nonacral melanoma were retrospectively evaluated using the Asan Medical Center database.

Results:

The male-to-female ratio and the mean age was 1:0.92 and 60.2 years for acral melanoma (n= 249), and 1:0.85 and 58.4 years for nonacral melanoma (n= 243), respectively. The demographic difference was not significant. Although prediagnosis duration was longer and the advanced stage was more common in acral melanoma than that in nonacral melanoma, the vertical growth phase was more common in nonacral melanoma than that in acral melanoma, whereas, the horizontal diameter is longer in acral melanoma than that in nonacral melanoma. Dissemination to lymph nodes was more common in acral melanoma than that in nonacral melanoma. Lymph node involvement was associated with deeper Breslow thickness in nonacral melanoma but not in acral melanoma. The degree of correlation of prediagnosis duration with horizontal diameter was remarkable in acral melanoma, but with Breslow thickness in nonacral melanoma. Overall survival was worse in acral melanoma than that in nonacral melanoma. The prognostic value of Breslow thickness was more remarkable in nonacral melanoma than that in acral melanoma.

Limitations:

This study is a retrospective, single-center design.

Conclusion:

Acral melanoma has a longer radial growth phase compared with nonacral melanoma. However, acral melanoma is commonly associated with lymph node dissemination which contributed to worse survival in acral melanoma than nonacral melanoma.
Gestion de l’immigration clandestine : la puissance normative de l’Union européenne à la dérive ?
Authors: Albessard Guillaume
Published: March 2021

L’immigration clandestine ne cesse d’alimenter les débats nationaux et européens. A travers cet article, la gestion européenne des phénomènes migratoires est mise en relation avec l’attachement historique à la norme et au soft power émanant de l’Union européenne. L’hypothèse principale consiste à affirmer que cette gestion représente une rupture avec le pouvoir normatif européen. Le poids des intérêts nationaux et l’approche intergouvernementale permettent d’abord de mettre au jour une vision « insécurisante » de l’immigration. Par ailleurs, le processus d’externalisation des frontières remet en cause l’attachement manifeste à la liberté et la sécurité. Quant à Frontex, son rôle semble paradoxal au regard des principes de bonne gouvernance et de rejet de la « norme », au profit de la force. Enfin, l’idée d’ « Europe forteresse » désignerait moins les effets de la politique migratoire européenne que ses intentions.
The State of the Cyprus Question
Authors: Renard Juliette
Published: March 2021

The Cyprus question raises a wide number of questions and issues to be investigated. Using scientific literature mainly, this present work is giving a broad overview and understanding of the main issues at stake, while acknowledging that not all the aspects of the conflict and its resolution are brought up. Moreover, a theoretical approach is used to define the type of reconciliation process ongoing in Cyprus and the several challenges it has faced in the past. Thus, this paper is structured as follows: firstly, the historical and political context in which the Cyprus question erupted is detailed. Afterwards, the notion of reconciliation is theoretically developed. In the third part, we enounce the issues that challenge and delay the peace process. That section acknowledges: one, the important role of the “motherlands” on Cyprus’ reconciliation; two, the issue of identity and nationalism in this context, and three, the rejection of the Annan plan and its consequences are mentioned. In the conclusion, a formulated response to the research question is provided and a short reflection over the “almost moral” imperative to reconcile former enemies concludes the paper.
