GOVERNANÇA METROPOLITANA NO CONTEXTO LATINO-AMERICANO: ESTRATÉGIAS E POTENCIALIDADES DA PESQUISA EM GEOGRAFIA POLÍTICA
Authors: Silva Augusto César Pinheiro da , Azevedo Daniel Abreu de
Published: February 2020

O debate contemporâneo sobre democracia participativa vai ao encontro das propostas de novos arranjos político-territoriais que buscam construir relações mais virtuosas entre cidadão e Estado. Nessa perspectiva, o artigo propõe discutir a governança metropolitana a partir da premissa de que novas estratégias de gestão de territórios são fundamentais para se pensar as dinâmicas contemporâneas do fenômeno urbano. Para tanto, utilizamos pesquisas já desenvolvidas sobre a Região Metropolitana do Rio de Janeiro para analisar a proposta de governança da região metropolitana da Cidade do México a partir da nova Constituição Política promulgada em 2018. Com uma investigação comparativa entre os dois casos, o artigo revela as virtudes e os impasses existentes na nova carta constitucional da capital mexicana e aponta características político-espaciais que precisam ser levadas em consideração para gerir uma das maiores aglomerações urbanas do mundo.

The common invariant subspace problem and Tarskiâs theorem
Authors: Pastuszak Grzegorz
Published: February 2020

This article presents a computable criterion for the existence of a common invariant subspace of $n\times n$ complex matrices $A_{1}, \dots ,A_{s}$ of a fixed dimension $1\leq d\leq n$. The approach taken in the paper is model-theoretic. Namely, the criterion is based on a constructive proof of the renowned Tarski's theorem on quantifier elimination in the theory $\ACF$ of algebraically closed fields. This means that for an arbitrary formula $\varphi$ of the language of fields, a quantifier-free formula $\varphi'$ such that $\varphi\lra\varphi'$ in $\ACF$ is given explicitly. The construction of $\varphi'$ is elementary and based on the effective Nullstellensatz. The existence of a common invariant subspace of $A_{1},\dots,A_{s}$ of dimension $d$ can be expressed in the first-order language of fields, and hence, the constructive version of Tarski's theorem yields the criterion. In addition, some applications of this criterion in quantum information theory are discussed.

Tridiagonal pairs of type III with height one
Authors: Li Xue , Hou Bo , Gao Suogang
Published: February 2020

Let K denote an algebraically closed field with characteristic 0. Let V denote a vector space over K with finite positive dimension, and let A, A∗ denote a tridiagonal pair on V  of diameter d.  Let V0, . . . , Vd  denote a standard ordering of  the eigenspaces of A on V , and let θ0, . . . , θd denote the corresponding eigenvalues of A. It is assumed that d ≥ 3.  Let ρi  denote the dimension of Vi. The sequence ρ0, ρ1, . . . , ρd is called the shape of the tridiagonal pair. It is known that ρ0 = 1 and there  exists  a  unique  integer  h (0 ≤ h ≤ d/2)  such  that  ρi−1 < ρi  for  1 ≤ i ≤ h,  ρi−1 = ρi  for  h < i ≤ d − h,  and  ρi−1 > ρi for d − h < i ≤ d. The integer h is known as the height of the tridiagonal pair. In this paper, it is showed that the shape of a tridiagonal pair of type III with height one is either 1, 2, 2, . . ., 2, 1 or 1, 3, 3, 1.  In each case, an interesting basis is found for V and the actions of A, A∗ on this basis are described.

La barbarización del ejército y de la corte oriental: el matrimonio de Serena y Estilicón.
Authors: Seijo Ibáñez Elisabet
Published: February 2020

On November 24th 380, Theodosius I celebrated his first aduentus in Constantinople and inaugurated a new period of the Roman Empire. Several women of his family arrived with him, and one of them was his adopted daughter Serena, who in 384 married Stilicho, a soldier born of a Roman woman and a Vandal. This union stands out as it was between a member of the imperial family and a man of barbarian origins (although Stilicho had Roman citizenship). The aim of this paper is to analyse the circumstances of the wedding and why Theodosius I allowed the nuptials.
Hipacio de Rufiniana y la lucha contra la idolatría y la magia en Bitinia durante el siglo V.
Authors: Jiménez Sánchez Juan Antonio
Published: February 2020

In the present work, we study the struggle against idolatry in Bithynia during the first half of the fifth century from the analysis of the Vita Hypatii, a biography written by Callinicus about 450. Hypatius, founder and first abbot of the monastery of Rufinianae (near Chalcedon) between 406 and 446, stood out as a tireless combatant against the remains of idolatrous cults which, despite being prohibited, were still practised in that region. According to his biographer, he used the supernatural powers derived from his holiness to confront idols and demons. In addition, and taking into account that Christian authorities identified magic and polytheism, Hypatius also fought the magical practices, stating at all times that the powers granted by God always beat those of the magicians.
Los monoteísmos abrahámicos y las imágenes: un panorama.
Authors: Boespflug François
Published: February 2020

This study is conducted through the form of a triptych. In the first part, we evoke the unprecedented situation in which the three monotheisms stand before the images, due, among other factors, to the Internet. We also aim to specify the meaning of every term used, in order to avoid simplifications in regard to their respective connections with the images. The second part, that is, the central panel of the triptych, intends to recall how each of the three religions, especially in its beginnings, dealt with images in general, and images of religious inspiration in particular. The third part examines the possible link between the hostility of nascent Islam towards the images and the well-known Controversy in Byzantium, also advocating the creation, within each of the three religions, of competent instances to designate those images that represent them properly.
Deep iterative vessel segmentation in OCT angiography
Authors: Pissas Theodoros , Bloch Edward , Cardoso M. Jorge , Flores Blanca , Georgiadis Odysseas , Jalali Sepehr , Ravasio Claudio , Stoyanov Danail , Da Cruz Lyndon , Bergeles Christos
Published: February 2020

This paper addresses retinal vessel segmentation on optical
coherence tomography angiography (OCT-A) images of the human
retina. Our approach is motivated by the need for high precision
image-guided delivery of regenerative therapies in vitreo-retinal
surgery. OCT-A visualizes macular vasculature, the main landmark of
the surgically targeted area, at a level of detail and spatial extent
unattainable by other imaging modalities. Thus, automatic extraction
of detailed vessel maps can ultimately inform surgical planning. We
address the task of delineation of the Superficial Vascular
Plexus in 2D Maximum Intensity Projections (MIP) of OCT-A
using convolutional neural networks that iteratively refine the
quality of the produced vessel segmentations. We demonstrate that the
proposed approach compares favourably to alternative network baselines
and graph-based methodologies through extensive experimental analysis,
using data collected from 50 subjects, including both individuals that
underwent surgery for structural macular abnormalities and healthy
subjects. Additionally, we demonstrate generalization to 3D
segmentation and narrower field-of-view OCT-A. In the future, the
extracted vessel maps will be leveraged for surgical planning and
semi-automated intraoperative navigation in vitreo-retinal
surgery.

LEGAL CERTAINTY AS AN EVALUATIVE CATEGORY IN CIVIL PROCEEDINGS
Authors: Bolovnev M.A. , Rekhtina I.V.
Published: February 2020

The article explores the effect of the legal certainty of civil procedure legislation and its application onthe creation of appropriate conditions for the effective implementation of justice. It is stressed that the lack of legal certainty, namely, its opposite — legal “uncertainty,” creates both legislative conflicts and, even moresignificantly, law enforcement problems, which significantly reduce the accessibility of justice to personsin need of judicial protection. The courts used different procedural rules, using a formalistic approach,jeopardizing the delivery of a lawful and justified judicial act. In order to overcome the state of legaluncertainty and, as a result, to improve the efficiency of legal proceedings, it is necessary to use techniquesof legal technique that do not lead to the emergence of causal rules of law. The model of the most generalrules is capable of being applicable to any emerging procedural situation, taking into account systemic andtargeted modes of interpretation. It is this approach to the construction of the system of legislation, togetherwith the subsequent application of the rules on the basis of internal conviction and judicial discretion, thatwill ensure the unity of judicial practice.

Knowledge and Awareness of Glaucoma and associated Risk Factors in Urban Community
Authors: Islam Shahariar
Published: February 2020

Background:Although glaucoma is the second leading cause of irreversible blindness globally, the condition shows no signs or symptoms until later stages. Knowledge about the disease is known to influence utilization of eye screening services. This study aimed at understanding knowledge and awareness of glaucoma and its associated risk factors among residents of urban community of Rajshahi district, Bangladesh.
Methods: This was a cross-sectional study with the use of a semi-structured questionnaire. Descriptive statistics were used to describe the socio-demographic characteristics, knowledge and awareness of glaucoma and associated risk factors.
Results: Out of a total of 185 respondents, 52.3 % were females and 0.5 % were aware of glaucoma. Majority (99.5 %) of the respondents were unaware of glaucoma and 24.3% (n=45) of the respondents didn't know that the disease can result in blindness. Only (16.2%) affirming that blindness from glaucoma is irreversible. 9.2 % of the respondents perceived themselves to be at risk of developing glaucoma. The results showed that age, sex, level of education, employment status, occupation, residential status, marital status and monthly income of the respondents (p<0.05) were statistically significant with glaucoma knowledge level. In addition, the result also showed that age, level of education, employment status, occupation, residential status, marital status and monthly income of the respondents (p<0.05) were statistically significant with glaucoma awareness.
Conclusion: Glaucoma awareness was not satisfactory and the findings also display inadequate knowledge about glaucoma. So there is a need to effectively inform and educate people about the disease.

Published: February 2020

In order to solve the problem that the total sugar content of the chlortetracycline fermentation tank can not be automatically detected online, a prediction method which combines the output recursive wavelet neural network and the Gauss process regression is proposed in this paper. A soft sensor model between the measurable parameters (inputs) and the total sugar content (output) of the chlortetracycline fermentation tank was established. The soft sensor model was trained by self updating algorithm. Based on field data, the accuracy and generalization ability of the soft sensor model were analyzed. It is shown that the prediction accuracy of the combined model proposed in this paper is better than that of other single models. The results demonstrate the superiority of the method, and MRE and RMSE are used to evaluate the performance of the soft sensor model. It shows that the prediction precision of the soft sensor model based on ORWNN-GPR combination is relatively high in the long period of fermentation, and is suitable for on-line prediction of the total sugar content of the chlortetracycline fermentation tank. The soft sensor method can effectively reduce the labor intensity of the analysts and saves the production cost for enterprise.
Service quality of the urban public transport companies and sustainable city logistics
Authors: Chocholac Jan , Sommerauerova Dana , Hyrslova Jaroslava , Kucera Tomas , Hruska Roman , Machalik Stanislav
Published: February 2020

The issue of sustainable city logistics has steadily been developed over the last decades. Urban public transport companies can make a significant contribution to the concept of sustainable city logistics. The customers’ perception and satisfaction regarding urban public transport companies can be associated with the increased use of their services. The preference for urban public transport reduces the use of individual car transport, which is linked to the environmental pillar of sustainability. For the customers, the level of the provided service is very important. The article is focused on the evaluation of the outcomes from the primary research concerning the service quality performed by the urban public transport companies in the Hradec-Pardubice residential agglomeration. The goal lies in identifying gaps in service quality. The method used in this article is representative primary research. The primary research was carried out in the form of structured personal interviews with a representative sample of respondents. Selected statistical methods were used to evaluate the data. The results are discussed in the context of published research studies. Research in this article found that respondents are more satisfied with the quality of services performed by the urban public transport companies, but the perception of individual service quality factors varies from one user group to another. The research also confirms a different perceptions regarding customer care and comfort by different age groups of respondents. The article implies that public transport companies should pay attention to setting fare prices for different groups of passengers.
Logistic regression in modeling and assessment of transport services
Authors: Borucka Anna
Published: February 2020

Transport companies operate in a dynamically developing and competitive market. Maintaining the already held position and further expansion requires adjusting the level of services provided to the needs and requirements of customers, as well as continuous surveying, monitoring and adjusting the implemented strategy. There are different methods for such an analysis. This article proposes logistic regression. The research was conducted on the basis of a distribution and trade company dealing with the supply of automotive spare parts. As the most profitable group of customers are local car repair shops, it was this group that was subject to analysis.

The quality of service assessment was considered from the point of view of delivery time. The dichotomous form of the predictor taking two values - late and on-time delivery - was determined. From among the possible ones, regressors whose influence was statistically significant and whose modification was possible were selected. The research showed which of them (and how strongly) affect the dependent variable, which allowed for modification of strategy and implementation of new solutions increasing the number of satisfied customers.
La langue polynomique, le concept phare de l’appareil critique corse
Authors: Di Meglio Alain
Published: February 2020

This article deals mainly with the notion of polynomie, which has occupied a large place in Corsican studies and in Corsican sociolinguistics. It is argued in this article that this concept developed by the sociolinguist Jean-Baptiste Marcellesi and the process it covers have allowed the emergence of Corsican as a “language”. The aim here is to propose a synthesis that takes the form of an advocacy for a bi-plurilingual societal model potentially better adapted to the Corsican political aspirations. The implications and applications in language didactics or literary production will be discussed in particular.

Non-occurrence of the Lavrentiev phenomenon for a class of convex nonautonomous Lagrangians
Authors: Mariconda Carlo , Treu Giulia
Published: February 2020

We consider the classical functional of the Calculus of Variations of the form

$$\begin{array}{}
\displaystyle
I(u)=\int\limits_{{\it\Omega}}F(x, u(x), \nabla u(x))\,dx,
\end{array}$$

where Ω is a bounded open subset of ℝn and F : Ω × ℝ × ℝn → ℝ is a Carathéodory convex function; the admissible functions u coincide with a prescribed Lipschitz function ϕ on ∂Ω. We formulate some conditions under which a given function in ϕ +
$\begin{array}{}
\displaystyle
W^{1,p}_0
\end{array}$(Ω) with I(u) < +∞ can be approximated in the W1,p norm and in energy by a sequence of smooth functions that coincide with ϕ on ∂Ω. As a particular case we obtain that the Lavrentiev phenomenon does not occur when F(x, u, ξ) = f(x, u) + h(x, ξ) is convex and x ↦ F(x, 0, 0) is sufficiently smooth.
High-performance monolayer MoS2 photodetector enabled by oxide stress liner using scalable chemical vapor growth method
Authors: Li Zhiwen , Wu Jing , Wang Cong , Zhang Han , Yu Wenjie , Lu Youming , Liu Xinke
Published: February 2020

MoS2, as a typical representative of two-dimensional semiconductors, has been explored extensively in applications of optoelectronic devices because of its adjustable bandgap. However, to date, the performance of the fabricated photodetectors has been very sensitive to the surrounding environment owing to the large surface-to-volume ratio. In this work, we report on large-scale, high-performance monolayer MoS2 photodetectors covered with a 3-nm Al2O3 layer grown by atomic layer deposition. In comparison with the device without the Al2O3 stress liner, both the photocurrent and responsivity are improved by over 10 times under 460-nm light illumination, which is due to the tensile strain induced by the Al2O3 layer. Further characterization demonstrated state-of-the-art performance of the device with a responsivity of 16.103 A W−1, gain of 191.80, NEP of 7.96 × 10−15 W Hz−1/2, and detectivity of 2.73 × 1010 Jones. Meanwhile, the response rise time of the photodetector also reduced greatly because of the increased electron mobility and reduced surface defects due to the Al2O3 stress liner. Our results demonstrate the potential application of large-scale strained monolayer MoS2 photodetectors in next-generation imaging systems.

Authors: Zhang Kai , Wang A. J.
Published: February 2020

The main purpose of this paper is to analyze the characteristics of the flow field in fan rotor. Nowadays the twisted and swept fan is the representative work of the forefront of aerospace engines. The tip clearance flow field can have a large impact on fan rotor performance. This article describes and uses the throttle method to obtain near stall condition. Near stall condition value simulation of the transonic fan rotor was carried out by CFX. The Proper Orthogonal Decomposition method was applied to the tip flow-field analysis. The main structure of the flow field can be distinguished by Proper Orthogonal Decomposition method. Then the flow structure is sorted according to energy. Disturbing fine flow structures can also be captured. This provides a comparative reference for flow field visualization. It also provides important data for the design of the fan.
Preparation and Application of Palladium Nanoparticle Impregnated Chloromethylated Polysulfone Matrix as an Efficient Catalytic Membrane for Oxidation of Alcohols
Authors: Mahdavi Hossein , Fayyazi Faeze
Published: February 2020

The use of palladium nanoparticles embedded in a chloromethylated Polysulfone (CMPSf) matrix was developed for highly efficient oxidation of primary and secondary alcohols to corresponding aldehyde and ketone in organic solvent free condition. Pd (Π)/bis (2, 4-dihydroxybenzaldehyde) chelate chemically incorporated onto CMPSf was used to prepare beneficial catalytic membranes. Chemical structure and thermal properties of resulting membranes were characterized via FTIR, 1HNMR, UV-vis, TGA and DSC techniques. Morphology and particle distribution throughout the catalytic membranes was elucidated using FE-SEM. An average particle size of Pd nanoparticles was estimated about 20 nm by XRD technique. ICP technique proved that no Pd particles were leached out of the membrane into the solutions; hence the as-prepared catalytic membranes could be used several times without significant loss in their activities. This is in good accordance with formation of chemical bond between Pd and polymer matrix.

Background: Medicalization has been a topic of discussion and research for over four decades. It is a known concept to researchers from a broad range of disciplines. Medicalization appears to be a concept that speaks to all, suggesting a shared understanding of what it constitutes. However, conceptually, the definition of medicalization has evolved over time. It is unknown how the concept is applied in empirical research, therefore following research question was answered: How is medicalization defined in empirical research and how do the definitions differ from each other? Methods: We performed a scoping review on the empirical research on medicalization. The 5 steps of a scoping review were followed: (1) Identifying the research question; (2) Identifying relevant studies; (3) Inclusion and exclusion criteria; (4) Charting the data; and (5) Collating, summarizing and reporting the results. The screening of 3027 papers resulted in the inclusion of 50 empirical studies in the review. Results: The application of the concept of medicalization within empirical studies proved quite diverse. The used conceptual definitions could be divided into 10 categories, which differed from each other subtly though importantly. The ten categories could be placed in a framework, containing two axes. The one axe represents a continuum from value neutral definitions to value laden definitions. The other axe represents a continuum from a micro to a macro perspective on medicalization. Conclusion: This review shows that empirical research on medicalization is quite heterogeneous in its definition of the concept. This reveals the richness and complexity of medicalization, once more, but also hinders the comparability of studies. Future empirical research should pay more attention to the choice made with regard to the definition of medialization and its applicability to the context of the study.

Published: February 2020

Background: Health system performance assessment (HSPA) is a major tool for evidence-based governance in health systems and patient/population-orientation is increasingly considered as an important aspect. The IPHA study aims (1) to undertake a comprehensive performance assessment of the German health system from a population perspective based on the intermediate and final dimensions defined by the World Health Organization (WHO) and (2) to identify differences in HSPA between (a) common user characteristics and (b) user types, which differ in their interactions and patterns of action within the health system. Methods and Analysis: A cross-sectional survey was conducted between October and December 2018 with statutorily and privately health insured to assess the German health system from a population perspective related to the past 12 months. The random sample consists of 32 000 persons insured by AOK Nordost and 20 000 persons insured by Debeka. Data from the survey will subsequently be linked with health insurance claims data at the individual level for each respondent who has given consent for data linkage. Claims data covers the time period January 1, 2017 to June 30, 2018. The combination of the 2 data sources allows to identify associations between insured patient characteristics and differences in the assessment of health system performance. The survey consists of 71 items measuring all final and intermediate health system goals defined by the WHO and user characteristics like health literacy, self-efficacy, the attention an individual pays to his or her health or disease, the personal network, autonomy, compliance and sociodemographics. The claims data contains information on morbidity, care delivery, service utilization, (co)payments and sociodemography. Discussion: The study represents a promising attempt to perform a holistic HSPA using a population perspective. For this purpose, a questionnaire was designed that contains both validated and new items in order to collect data on all relevant health system dimensions. In particular, linking survey data on HSPA with claims data is of high potential for assessing and analysing determinants of health system performance from the population perspective.
Portrait at an Exhibition
Authors: Kottenstette David T.
Published: February 2020

This work examines a gay survivor’s grief after his partner’s death from cardiac arrest. Their twenty-four years in relationship inform twenty years of grief. His lived experience questions the often inflexibility of heteronormativity in a world about to change. Like a portrait at exhibition, an image speaks long after the brushstrokes stop and the canvas dries. We are asked to see new things in a painting every time it’s viewed.
Contemporary Autoethnography Is Digital Autoethnography
Authors: Dunn Tasha R. , Myers W. Benjamin
Published: February 2020

Autoethnography has become legitimized through its ability to connect culture to personal experiences. This legitimization has occurred alongside a titanic shift in communication made possible by digital technology, which has rapidly transformed, multiplied, and mediated the ways through which we engage one another. This essay explores and exemplifies the necessity of autoethnography to evolve in concert with the ways our lives have become inextricably tethered to digital technology. Due to this shift, we propose that contemporary autoethnography is digital autoethnography, a method we propose that relies on personal experience(s) to foreground how meaning is made among people occupying and connected to digital spaces. Digital autoethnography is distinguishable from traditional autoethnography because the cultures analyzed are not primarily physical; they are digital. In short, the work of digital autoethnography is situated within and concerned about digital spaces and the lived experiences, interactions, and meaning-making within and beside these contexts. Embracing digital autoethnography pushes us to consider and reflect upon the ways we have changed over time with the influx of digital technology. Additionally, the method provides a framework to keep autoethnography relevant in spite of the inevitable changes to human experience that will occur as digital connectivity becomes increasingly enmeshed in our everyday lives.
Two Nations
Authors: Clayton Dewey M.
Published: February 2020

The landmark 1954 Brown v. Board of Education Supreme Court decision outlawed public school segregation and was the catalyst for the nonviolent civil rights movement and some positive change for African Americans. However, in 1967, race riots broke out in largely African American urban districts across America, leading President Lyndon Johnson to form the Kerner Commission to determine the underlying causes of the riots. This paper explores the causes of the riots and the government’s response to them after the Kerner Commission’s findings, and then uses critical race theory as a theoretical framework to determine why institutional racism continues to be pervasive in society. The author focuses on three main areas: school desegregation; mass incarceration and police brutality; and sports, race, and activism to discuss the lack of progress between the Kerner Commission report and today.

Restoring the Critical Power of Curriculum Studies to Transform the Society
Authors: Subkhan Edi
Published: February 2020

Curriculum Studies has evolved for years and already gain its very honorable place in the heart of education studies. Most education scholars said that curriculum is important, curriculum is the heart of education (Priestley & Philippou, 2019), and in so doing curriculum studies. But, how this very important field of studies survive and evolve in this vulnerable and unpredictable era which neoliberal agendas dominating almost educational field around the world? We are witnessing how the culture of positivism, competition ideology, New Managerialism, and even racism and hatred, poisoning and deflect the aims of education. On the other hand, there also a crisis in curriculum studies in which curriculum seems only struggling and focusing on theoretical discourse without any significant influences on the material world. Right in this very difficult position of curriculum studies, the work of Wayne Au is significant. He wrote very important book entitled “Critical Curriculum Studies: Education, Consciousness, and the Politics of Knowing” in 2012. Which Michael Apple in the series editor introduction said that this work is ambitious and provocative, because it seeks theoretical and epistemological foundation of critical curriculum studies that challenges many basic assumptions about curriculum (Au, 2012, p. xv). I am agree with what has Apple said and through this review book article I would say that Au’s work has huge contribution to the development of curriculum studies in this contemporary era, especially in order to become a tool to change or transform the society to be more democratic and just.
O euro: moeda única ou Currency Booard?
Authors: Costas Antón
Published: February 2020

Neste artigo preguntámonos, en primeiro lugar, por que o deseño do euro non incor-porou os mecanismos necesarios para resolver situacións de crise como a actual. A hipótese que manexamos é que, en contra do que frecuentemente se di, o euro seguiu un modelo que responde máis á lóxica dunha “currency board” dun mercado común que ao dunha moeda única dunha unidade política. En segundo lugar, formulamos a cuestión de se a actual eurozona pode ir máis alá desa lóxica para transformarse nunha verdadeira moeda común. Para iso preguntá-monos en que medida a actual crise de débeda pode acabar sendo unha crise integradora ou, pola contra, desintegradora da eurozona, identificando os factores que poden determinar que o resultado sexa un ou outro. A conclusión é que o camiño cara ao goberno económico do euro será longo e de resultados impredicibles. O avance necesita dun novo impulso rexenerador do proxecto europeo. Ese impulso non poderá vir dos actuais plans de austeridade. A integración dos novos, hoxe afectados por un elevado nivel de desemprego, pode servir de obxectivo para dar ese novo impulso.

Published: February 2020

A valoración inmobiliaria é unha actividade de suma importancia nas economías modernas. Co-mo tal, o obxectivo deste artigo é analizar a relación entre o rendemento e as taxas de capitalización do mercado inmobiliario portugués, comparando os seus resultados a nivel municipal. Analízanse series de datos de catro anos (2006-2009) relativas ás rendas en euros/m2 no mercado inmobiliario portugués a ni-vel municipal, que permitirán determinar as medias das rendas e das taxas de capitalización das series, e realizar unha comparación destas a través da análise clúster. Os resultados obtidos demostran que o mé-todo de rendas pode utilizarse para explicar o valor da oferta das vivendas no nivel municipal.
O uso dunha cota variable de royalty para preservar as reservas de petróleo
Authors: Losada Moreira Joao Manoel , Juliani Lucélia Ivonete , Guy Guerra Sinclair Mallet
Published: February 2020

Neste traballo analízase a posibilidade de utilizar unha cota variable de royalty para inducir as empresas nunha contorna competitiva a preservar as reservas de petróleo. Inicialmente, desenvolveuse un modelo da evolución das reservas de petróleo, dispoñible para a extracción por un empresario en réxime de competencia, incluíndose na expresión do beneficio económico a cota variable de royalty. O modelo formúlase como unha función loxística que describe o comportamento dos recursos naturais renovables. Os resultados obtidos mostran que a situación que maximiza o beneficio económico do empresario e redu-ce a taxa de extracción do petróleo se produce cando a rendibilidade neta do empresario se aproxima á súa taxa de xuro relevante. Isto é debido á propensión do empresario a aumentar a taxa de extracción dos recursos naturais para darlles cabida ás variacións na rendibilidade causadas polo mercado. A introdución dunha cota variable de royalty proporciona unha variable que pode compensar estas flutuacións e ofrecer-lle ao empresario unha rendibilidade próxima á súa taxa de xuro relevante. Os resultados mostran que é posible regular, dentro duns límites, o nivel de reservas de recursos naturais e obter recursos financeiros para levar a cabo políticas sociais.
