Authors: Guerra Ana Isabel , Lopes João Carlos
Published: March 2023

A União Europeia tem sugerido várias abordagens para diminuir assimetrias regionais e para o desenvolvimento das suas zonas rurais. O objetivo deste artigo é estudar uma dessas medidas, o Programa Jovens Agricultores, na zona rural de Trás-os-Montes, uma área ameaçada pelo envelhecimento e despovoamento. A iniciativa poderá reverter estes fenómenos e tornar o estilo de vida rural atrativo para as gerações mais novas. Mas serão estes agricultores um vetor de inovação para Trás-os-Montes? Terão uma consciencialização ambiental e sustentável sólida? Conhecerão o modelo de economia circular? Será o uso digital uma realidade? Estarão os dirigentes associativos a encorajar um desenvolvimento sustentável? A tentativa de resposta a estas questões é feita através de um inquérito por questionário distribuído a uma amostra representativa de jovens agricultores e através de entrevistas aos seus principais dirigentes associativos. Em termos gerais, os resultados apontam para uma conclusão positiva, a de que os jovens agricultores podem trazer mudança e desenvolvimento a Trás-os-Montes.
Regional Deconcentration in Brazilian Economy: Putting some Lights on the Industrial Sector in the 19952018 Period
Authors: Monteiro Neto Aristides , De Oliveira Silva Raphael , Severian Danilo
Published: March 2023

The article analyzes the trajectory of industry and its reverberations across Brazilian regions during the period 1995-2018. The technical restructuring of industrial activities is investigated through the macroregional scales (North, Northeast, Southeast, South and Midwest) and the relevant industrial agglomerations. Results have indicated that the recent movements of regional deconcentration continue to occur but are on a small scale and mainly linked to intensive activities in natural resources and labor. The perceived changes in the composition of the industrial sector particularly in the manufacturing industry –, as something new within Brazil’s economic development, are an indication of how this sector has lost its relevance in the expansion of the national economy.

Determinantes de los flujos de remesas en el Ecuador, desde una perspectiva territorial
Authors: Andrade-Herrera Carlos , Correa-Quezada Ronny
Published: March 2023

El objetivo de la investigación es determinar los factores que influyen en el envío de remesas (en dólares) de Estados Unidos y España a Ecuador, en el periodo 2000 – 2020. La metodología empleada son los modelos de serie con corrección de errores estándar, tendencia secular o de largo plazo. Los resultados muestran que el crecimiento de la actividad económica, medida por medio del Producto Interno Bruto per cápita, empleo, salarios, tipo de cambio (euro/dólar), aumenta la remisión de estos flujos a Ecuador y consecuentemente el desarrollo local. Es decir, mientras estas economías registren tasas de crecimiento positivas, los migrantes ecuatorianos tendrían más oportunidades de aumentar sus ingresos y, por tanto, enviar mayores cantidades de remesas hacia sus localidades. En este escenario, los flujos de remesas son determinados por ciertas variables macroeconómicas (crecimiento del PIB, salario, empleo y tipo de cambio) de los países anfitriones que afectan directamente a los ingresos de los emigrados.

The first cases of the COVID-19 disease in Mexico came from abroad in February 2020. Communitarian propagation accelerated the infection in the big metropolitan areas of Mexico, such as Valle de México Metropolitan Zone (VMMZ), were located the biggest people concentration in the country. In this study, we evaluate the spatial distribution of the positive cases and deaths in VMMZ at municipality level through a spatial econometric model that include socio demographic and economic variables, besides we explore the active cases in Ciudad de México at neighborhood level. We found significant spatial effects, most notably in positive cases, that could help to explain the stage of the disease, in both levels municipality and neighborhood. The model shed light to observe how the COVID19 hits harder at the municipalities more densely populated and where the urbanization process was deeper, compared with those peripheral, nevertheless, worst living conditions also exhibit a positive relationship, in both positive cases and deaths.
A Atracção das Universidades em Regiões Economicamente Deprimidas. O caso da Universidade de Évora
Authors: Rego Conceição , Caleiro António
Published: March 2023

Como se sabe, as universidades são fontes de significativos efeitos multiplicadores na actividade económica das regiões onde estão inseridas; no caso das regiões deprimidas, a importância desta influência acentua-se bastante. Este é certamente o caso da Universidade de Évora (U.E.), localizada no Alentejo, uma das regiões mais pobres da União Europeia, na medida em que este estabelecimento de ensino superior tem vindo claramente a contribuir para o desenvolvimento da economia local. Contudo, para além do efeito directo na actividade económica do Alentejo, da presença da Universidade de Évora na região também decorrem, por um lado, efeitos demográficos, cativando população que passa a viver na cidade e, por outro lado, atraindo estudantes que residem na cidade durante o período em que efectuam os seus cursos. Este trabalho propõe-se abordar este segundo aspecto, verificando os motivos pelos quais os estudantes, oriundos um pouco de todo o país, escolhem a U.E. e os seus cursos para realizarem a sua formação. Esta análise, efectuada com recurso a técnicas econométricas, mostra quais são os factores determinantes da atracção exercida pela U.E., em geral, e pelos seus cursos, em particular, sobre os alunos ingressados no ensino superior
Modelos de Avaliação Imobiliária e Fundiária Aplicados ao Mercado de Escritórios
Authors: Rebelo Emília Maria Malcata
Published: March 2023

Neste artigo desenvolve-se um modelo integrado de avaliação do imobiliário de escritórios e de rendas do solo urbano para uso de escritórios, que consiste num conjunto de ferramentas interactivas, incluindo um interface cartográfico, com o objectivo de apoiar as decisões de planeamento e fiscais dos agentes municipais, e a respectiva implementação. É aplicado como estudo de caso, à cidade do Porto (Portugal). Propõe-se o reforço do papel do Planeamento e dos poderes municipais nos mercados de propriedade, através da redefinição da tributação imobiliária e fundiária (adaptando melhor os instrumentos tributários às realidades locais específicas), evitando comportamentos especulativos, e permitindo a apropriação social de (pelos menos) parte das “maisvalias” decorrentes da actuação da administração pública.
Quão distantes estão as regiões portuguesas? Uma aplicação de escalonamento multidimensional
Authors: Guerreiro Gertrudes , Caleiro António
Published: March 2023

Apesar de ser um país pequeno, Portugal caracterizase por disparidades regionais significativas, as quais se tornam evidentes a partir da análise de numerosos indicadores como o nível de rendimento ou a taxa de desemprego. Estas disparidades regionais adquirem características que, em certo sentido, não respeitam o padrão tradicional que seria de esperar, o qual apontaria no sentido de uma diminuição das condições de vida, à medida que aumenta a distância de cada região, à região onde a prosperidade económica é mais elevada. De facto, isto significa que, para além do mapa geográfico, é possível construir um mapa alternativo das regiões de Portugal o qual, pelas suas características, é certamente muito mais interessante do ponto de vista da economia regional. Tal pode ser feito, recorrendo ao escalonamento multidimensional, o qual permite representar graficamente as unidades espaciais de maneira a reproduzir, tanto quanto possível, as distâncias económicas entre elas, medidas por indicadores tradicionais. A análise dos resultados do escalonamento multidimensional torna, então, possível, por um lado, verificar como as distâncias geográficas se relacionam com as distâncias económicas e, por outro lado, verificar se as políticas económicas regionais portuguesas contribuíram para uma diminuição daquelas disparidades regionais.
Estarão os Portugueses a ‘Votar com os Pés’? Uma Apreciação Sobre a Questão
Authors: Caleiro António
Published: March 2023

Como é sabido, os movimentos migratórios à escala regional são fruto de uma diversidade de factores. Sendo entendidos como uma reacção, por parte da população, a desvantagens (inaceitáveis) de natureza económica apresentadas pela região de origem, estes movimentos demográficos constituem um importante exemplo da chamada ‘votação com os pés’. Claramente, a inexistência (ou a mera ineficácia) de políticas regionais que tenham como objectivo combater este fenómeno acarreta a inevitável desertificação humana a qual, certamente, constitui um crucial entrave ao desenvolvimento regional. O objectivo principal deste trabalho é o de verificar se existe evidência empírica, em Portugal, suportando a hipótese de que aos movimentos migratórios regionais se pode associar o fenómeno da ‘votação com os pés’. Dado que o espaço de tempo decorrido entre os dois últimos Censos da População nos parece ser suficiente para se puderem observar com alguma segurança as tendências migratórias verificadas em Portugal, aquele objectivo pretende ser atingido usando os dados dos Censos de 1991 e 2001, recorrendo a uma metodologia que se baseia no uso de técnicas estatísticas especialmente adequadas no tratamento de variáveis que se apresentam localizadas no espaço nacional.

El Síndrome de Williams-Beuren (SWB) es un síndrome congénito generado a partir de una microdeleción hemicigótica (presente en una sola copia del cromosoma), ocurrida en el brazo largo del cromosoma 7 (7, brazo q11: 23), involucrando una región que alberga aproximadamente 28 genes. Entre estos genes se encuentra el responsable por la producción de una proteína llamada elastina, que es un componente importante de las fibras elásticas del tejido conectivo. La deleción en el gen de la elastina explica varias de las características del Síndrome de Williams-Beuren, como las alteraciones faciales, cardiopatías y envejecimiento precoz de la piel. El SWB posee características típicas faciales, cardiopatías como la estenosis aórtica supravalvular y el comportamiento de sociabilidad excesiva. Este estudio, a través de la revisión bibliográfica, tuvo como objetivo comprender los aspectos clínicos relacionados con el síndrome de Williams-Beuren, así como su fenotipo conductual. El SWB es un problema congénito raro que trae en su génesis enfermedades orgánicas y características faciales típicas que hacen el diagnóstico del síndrome específico. El tratamiento consiste en intervenciones específicas para la reparación de cardiopatías, anomalías oftalmológicas, anomalías pulmonares e incluso tratamientos terapéuticos que ayuden al desarrollo conductual adecuado de los individuos que viven con la Síndrome de Williams-Beuren.

Moda, arte e sociedade: O pioneirismo da maison Canadá-de-Luxe e a emergência da indústria fashion nacional nos anos 1950
Authors: Oliveira Claudia de
Published: March 2023

Hoje, a moda brasileira ganhou destaque e reconhecimento internacional por seu estilo especial de criar roupas e lançar tendências: movimento que procura unir a diversidade cultural única do Brasil ao que há de mais contemporâneo e global em design de moda em todo o mundo. Contudo, o sistema de moda atual tem uma história, e podemos dizer que seu ponto de partida remonta à década de 1950 e foi parte de grande engrenagem que articulou vários setores industriais, segmentos sociais e políticos dentro e fora do campo da moda. É dentro desta grande engrenagem que podemos posicionar a Canadá-de-Luxe e as criações de d. Mena Fiala. D. Mena jamais se propôs a criar uma moda de vanguarda brasileira, mas foi incansável na consolidação de uma moda nacional sintonizada com o que se produzia fora, especialmente, na Paris do Pós Guerra. Armada de técnica elaborada, que ela própria inventou, não parou de desenvolvê-la e aperfeiçoá-la sem abandonar os cânones que constituem o estilo: rigor, esforço, persistência e beleza. A casa Canadá é referência quando se fala em moda no Brasil nos anos 1950, e isso se deve ao esforço incansável de Mena Fiala e Cândida Gluzman em transformar a marca Canadá em referência de beleza e elegância.Palavras-chave: moda, vanguarda, elegância.

Familie og følelser i det romerske Kartago
Authors: Carlsen Jesper
Published: March 2023

This article discusses the epitaphs with epithets from two burial grounds at Carthage excavated by Alfred-Louis Delattre in the last decades of the 19th century. He found more than 900 Latin inscriptions that can be dated between the late first century and the early third century CE. Most of those buried at the so-called ‘cimetières des officiales’ were imperial slaves and freedmen together with their relatives and include almost 1300 individuals. Epithets occur just in about sixty epitaphs or about 6 % of the inscriptions from the imperial burial grounds at Carthage. The inscriptions are mostly short with certain conventions. The employment of epithets characterized the moral qualities of the commemorated seen from the commemorator’s point of view and is an expression of feelings, emotions and grief. The epitaphs from Carthage come from a well-defined context within a well-defined group, which may share the same feelings and be called an emotional community. The analysis of the most common epithets demonstrates remarkable differences between their use at Carthage and in the funerary inscriptions found in Rome.

Le présent article a pour but d’explorer comment, à travers des époques différentes (1929-2009), la polyphonie, décrite initialement par Mikhaïl Bakhtine à l’aide de l’oeuvre de Dostoïevski, a évolué pour refléter une polyphonie plus contemporaine dans l’oeuvre de Marie-Claire Blais, plus précisément dans Naissance de Rebecca à l’ère des tourments, en devenant une polyphonie paradoxale où le foisonnement des voix ne conduit pas à la communication et où les multiples faits particuliers ne peuvent être isolés. Les deux approches, bien que différentes, mènent à un effet de globalité où la narration joue un rôle prépondérant et où les événements relatés ne signifient que s’ils sont pris dans leur ensemble.
DYNAMICS OF DESIRE: GIFT GIVING AND RECIPROCITY IN ANCIENT GREEK HOMOEROTIC COURTSHIP COURTSHIP
Authors: Bednarek Bartłomiej
Published: March 2023

The article addresses the problem of reciprocity in homoerotic relationships in classical Athens. According to the more traditional approach, the pecking ord er model ’’, these typically a symmetrical relationships almost inevitably involved humiliation of one of the partners, who literally or metaphorically assumed a passive and therefore u n manly role. Although more recent studies tend to underline the arti fici al cha racter of these schola rly reconstructions, they still fail to account for the nuances of ancient homoerotic courtship. I argue that some sources often used by scholars as reflec t ing negative attitudes towards homoeroticism may actually t estify to the existenc e of very clear rules of highly valued and praised behaviours of passive partners. T h ese rules formed an implicit grammar of social actions but were never explicitly codified.

The rotation, translation, and vibration of many amino acid molecules fall in the terahertz (THz) region, thus qualitative and quantitative researches on amino acids can be carried out through their THz absorption characteristic fingerprint peaks. In this paper, the room temperature THz absorption spectra of DL-glutamic acid and its monohydrate at 0.5-3.0THz were measured by utilizing terahertz time-domain spectroscopy (THz-TDS). It is found that the THz characteristic peaks of these two amino acids are obviously different. Moreover, according to the change of the absorption amplitude of the characteristic absorption peak (1.24THz) of DL-glutamate monohydrate at different sample concentrations, a quantitative analysis was carried out on the mixed samples of DL-glutamate and its monohydrate, and then the quantitative analysis formula was also verified. In addition, the optical mode of DL-glutamic acid and its monohydrate in THz region was predicted by using density functional theory (DFT). Under the condition that the theoretical data matched with the experimental peaks, the origins of THz absorption peaks obtained in the experiment were discussed and summarized. The results show that the THz characteristic peaks (<2.80THz) of DL-glutamic acid and its monohydrate come from the intermolecular interaction modes, and the other absorption peaks are resulted from the combination of intermolecular and intramolecular interaction modes.

Due to the continuous variant of the COVID-19 virus, the present epidemic may persist in a long time, and each breakout displays strongly region/time-dependent characteristics. Prediction for each specific bursting is the basic task for the corresponding strategies. However, the refinement of the prevention and control measures implies generally the limitation of available records for the evolution of the spreading, which leads to a special difficulty for predictions. Taking into account of the interdependence of people's travel behaviors and the epidemic spreading, we proposed an Modified Logistic Model to mimic the COVID-19 epidemic spreading, to predict with limited epidemic related records the evolutionary behaviors for a specific bursting in a megacity. It reproduces successively the COVID-19 infected records in Shanghai China in the duration from March 1 to June 28,2022. Since December 7, 2022 when a new refinement of the prevention and control measures is adopted in the Mainland China, the COVID-19 epidemic blew up on a national-wide scale, and the drug "ibuprofen" is widely taken by the infected people themselves to relieve the fever symptoms. A reasonable assumption is that the total searching times for the word "ibuprofen" is a good representation for the amount of the infected people. By using the searching times for the word "ibuprofen" provided on Baidu, a famous searching platform in Mainland China, we estimated the parameters in the Modified Logistic Model and predicted subsequently the epidemic spreading behavior in Shanghai China starting from December 1, 2022. It will persist for a period of 72 days. The amount of the infected people will increase exponentially in the duration from the beginning to the 24th day, reach summit at the 31th day, and decrease exponentially in the duration from the 38th day to the end. Within the two weeks centered at the summit the increasing and decreasing speeds are both significantly small, but the increased amount of infected people each day is significantly large. The characteristics for this prediction match very well with that for the amount of metro passengers in Shanghai. As a proposal, the related departments should setup a monitoring system according to the principles of sampling in statistics, composing of some communities, hospitals, etc., to provide researchers with reliable records for prediction.
Evolution of neural activity in circuits bridging sensory and abstract knowledge

Published: March 2023

The ability to associate sensory stimuli with abstract classes is critical for survival. How are these associations implemented in brain circuits? And what governs how neural activity evolves during abstract knowledge acquisition? To investigate these questions, we consider a circuit model that learns to map sensory input to abstract classes via gradient-descent synaptic plasticity. We focus on typical neuroscience tasks (simple, and context-dependent, categorization), and study how both synaptic connectivity and neural activity evolve during learning. To make contact with the current generation of experiments, we analyze activity via standard measures such as selectivity, correlations, and tuning symmetry. We find that the model is able to recapitulate experimental observations, including seemingly disparate ones. We determine how, in the model, the behaviour of these measures depends on details of the circuit and the task. These dependencies make experimentally testable predictions about the circuitry supporting abstract knowledge acquisition in the brain.
Behavioral dissection of hunger states in Drosophila

Published: March 2023

Hunger is a motivational drive that promotes feeding, and it can be generated by the physiological need to consume nutrients as well as the hedonic properties of food. Brain circuits and mechanisms that regulate feeding have been described, but which of these contribute to the generation of motive forces that drive feeding is unclear. Here, we describe our first efforts at behaviorally and neuronally distinguishing hedonic from homeostatic hunger states in Drosophila melanogaster and propose that this system can be used as a model to dissect the molecular mechanisms that underlie feeding motivation. We visually identify and quantify behaviors exhibited by hungry flies and find that increased feeding duration is a behavioral signature of hedonic feeding motivation. Using a genetically encoded marker of neuronal activity, we find that the mushroom body (MB) lobes are activated by hedonic food environments, and we use optogenetic inhibition to implicate a dopaminergic neuron cluster (protocerebral anterior medial [PAM]) to α’/β’ MB circuit in hedonic feeding motivation. The identification of discrete hunger states in flies and the development of behavioral assays to measure them offers a framework to begin dissecting the molecular and circuit mechanisms that generate motivational states in the brain.
Quality management and sustainability in logistics service providers: case study in brazilian company
Authors: Junqueira Carolina de Oliveira , Grande Marcia Mazzeo
Published: March 2023

Logistics operators have become important agents in supply chains, due to the current trend of outsourcing logistical activities by companies. In this way, the level of quality of the services provided is an important aspect for the competitiveness of companies. In addition, the sustainability aspect has become relevant, given the environmental impact caused by logistics activities. Studies have shown that there are points of convergence between quality management approaches and sustainable practices. The objective of this work was to analyze aspects of quality management and sustainability in Brazilian logistics operators, from the perspective of the company contracting these services. To this end, a case study was conducted at a large company that outsources its logistics activities. The five main logistics operators providing services to the company were considered. The analysis was carried out on the basis of a model that integrates sustainability and quality management criteria. Quality assets, processes and dimensions were considered.  It was found that the contracted logistics operators have a wide portfolio of services offered, quality assets and well-defined processes. However, sustainability practices are still in their infancy.

Published: March 2023

Este artigo tem como objetivo verificar a importância da agropecuária familiar na produção agropecuária baiana, comparativamente à agropecuária patronal. Pretende-se estimar funções de produção para os segmentos produtivos familiar e patronal, por análise de regressão múltipla multivariada, para obter as elasticidades de produção para avaliar os impactos dos fatores de produção sobre o valor bruto da produção. A análise comparativa entre os segmentos familiar e patronal também foi feita por meio de análise tabular. Os dados utilizados foram obtidos do Instituto Brasileiro de Geografia e Estatística (IBGE), mais especificamente, do Censo Agropecuário de 2017. Observou-se grande heterogeneidade nas condições de produção entre e dentro de cada segmento. Foram verificadas diferenças estatisticamente significativas entre os segmentos produtivos e a variável relacionado às despesas de produção foi a que apresentou o maior impacto sobre a quantidade produzida. A agropecuária familiar fez uso do insumo trabalho em maior intensidade, enquanto a patronal foi mais intensiva em capital. A agropecuária familiar mostrou-se importante para a agropecuária baiana, contudo, alguns índices de produtividade ainda são baixos.
