Mapeamento temático na análise da paisagem: bacia hidrográfica do Rio Urussanga, Santa Catarina, Brasil
Authors: Dias Adriano De Oliveira , Ladwig Nilzo Ivo , Conto Danrlei De
Published: June 2020

Desde o início do século XVI, o desenvolvimento de atividades antrópicas em território brasileiro tem provocado a fragmentação da formação florestal original, processo que ocorreu na bacia hidrográfica do rio Urussanga. Nesse contexto, foi definido o objetivo do estudo que consiste em analisar a dinâmica espaçotemporal da paisagem da bacia hidrográfica para identificar as mudanças na cobertura florestal. Para tanto, foram utilizadas imagens orbitais do sistema sensor Landsat (5 – sensor TM e 8 – sensor OLI) – dos anos de 1986, 2001 e 2016. Os mapas temáticos obtidos no processamento das imagens geraram os dados que permitiram analisar a dinâmica espaçotemporal do uso e cobertura da terra na bacia hidrográfica do rio Urussanga entre os anos de 1986 e 2016. A análise foi subdividida em dois períodos – 1986 a 2001 e 2001 a 2016. Os resultados mostraram que, em ambos os períodos analisados, a cobertura florestal (classe Vegetação Arbórea - Arbustiva) apresentou redução espacial na bacia. Dentre as classes de uso e cobertura da terra que apresentaram expansão territorial, nos períodos analisados, tem-se as classes Área Urbanizada e Massa de Água. Os resultados analisados apontaram a evolução da rizicultura e a urbanização dos municípios. Conclui-se que os mapas temáticos elaborados representam a dinâmica de transformação da paisagem na bacia hidrográfica. São documentos que poderão encaminhar o plano de bacia e servir de base para que o comitê possa desenvolver ações de sensibilização com relação ao uso e ocupação do território e a importância do recurso hídrico às organizações sociais.

Authors: Bagolin Izete Pengo , Lindemayer Natália , Fraga Luana Dos Santos
Published: June 2020

O objetivo deste artigo é comparar o bem-estar pessoal de beneficiários e não beneficiários do Programa Bolsa Família, que residem em domicílios bi ou monoparentais, podendo ser chefiados por homens ou mulheres. Para tal, é construído um Indicador Multidimensional de Bem-Estar (IMBE), empregando os microdados do Censo de 2010 utilizando uma metodologia similar à do Índice de Desenvolvimento Humano. Os resultados mostram que, em relação aos beneficiários, as pessoas que residem em domicílios chefiados por mulheres apresentam melhores condições de bem-estar do que as que vivem nos chefiados por homens. Porém, o indicador aponta que este bem-estar é inferior ao alcançado pelas pessoas que vivem em domicílios chefiados por não beneficiários, sejam mulheres ou homens.
Reading Graphic Design in Cultural Context
Authors: Lees-Maffei Grace , Maffei Nicolas P.
Published: June 2020

Reading Graphic Design in Cultural Context explains key ways of understanding and interpreting the graphic designs we see all around us, in advertising, branding, packaging and fashion. It situates these designs in their cultural and social contexts.

Drawing examples from a range of design genres, leading design historians Grace Lees-Maffei and Nicolas P. Maffei explain theories of semiotics, postmodernism and globalization, and consider issues and debates within visual communication theory such as legibility, the relationship of word and image, gender and identity, and the impact of digital forms on design. Their discussion takes in well-known brands like Alessi, Nike, Unilever and Tate, and everyday designed things including slogan t-shirts, car advertising, ebooks, corporate logos, posters and music packaging.
Remote sensing of two exceptional winter aerosol pollution events and representativeness of ground-based measurements
Authors: Baron Alexandre , Chazette Patrick , Totems Julien
Published: June 2020

Abstract. Two intense winter aerosol pollution events, which took place in winter 2016–2017 in Paris, were monitored using a ground-based N2-Raman
lidar, in the framework of WASLIP (Winter Aerosol Survey by Lidar In Paris), a dedicated field campaign that was carried out in this area from
1 November 2016 to 31 January 2017. The data analysis uses the synergy between ground-based and spaceborne lidar observations and data from the air
quality monitoring network Airparif. The first severe aerosol pollution event began on 30 November 2016 and ended on 2 December, concerning
a circular area of ∼250 km in diameter around Paris. The maximum PM10 was 121±63 µg m−3 (regional spatial
average ± SD) for the Airparif ground-based PM monitoring stations, and the aerosol extinction coefficient (AEC) ranged from 0.2 to
1 km−1. The second event took place from 20 to 23 January which covered all of the northwestern Europe, with maxima of PM10
around 156±33 µg m−3 and AEC between 0.6 and 1 km−1, within the winter atmospheric boundary layer. Although these
two major aerosol pollution events did not occur under identical anticyclonic weather conditions, they share very low planetary boundary layer (PBL)
heights, down to 300 m above ground level. Moreover, they are associated with significantly different aerosol lidar ratios:
72±15 and 56±15 sr, respectively in December and January. Such results are consistent with available spaceborne lidar data, 70±25 sr from CALIOP (Cloud-Aerosol Lidar and Infrared Pathfinder Satellite Observations), and values found in the literature. During these
two events, the continuous temporal evolution of the aerosol extinction coefficient allows us to investigate the representativeness of optical
parameters found in the planetary boundary layer to assess surface aerosol concentration. No one-to-one relationship between the aerosol optical
thickness (AOT) and PM2.5 values stands out within our study. In contrast, the maximum aerosol extinction coefficient found within the
planetary boundary layer correlates well with PM2.5 at the ground (R2∼0.75, specific extinction cross section of
9.4 m2 g−1) for these polluted events. Thus this lidar-derived aerosol extinction coefficient is identified as a consistent
variable to monitor the pollution during winter events.

Published: June 2020

Abstract. The energetic electron content in the Van Allen radiation belts surrounding the Earth can vary dramatically at several timescales, and these strong electron fluxes present a hazard for spacecraft traversing the belts. The belt response to solar wind driving is, however, largely unpredictable, and the direct response to specific large-scale heliospheric structures has not been considered previously. We investigate the immediate response of electron fluxes in the outer belt that are driven by sheath regions preceding interplanetary coronal mass ejections and the associated wave activity in the inner magnetosphere. We consider the events recorded from 2012 to 2018 in the Van Allen Probes era to utilise the energy- and radial-distance-resolved electron flux observations of the twin spacecraft mission. We perform a statistical study of the events by using the superposed epoch analysis in which the sheaths are superposed separately from the ejecta and resampled to the same average duration. Our results show that the wave power of ultra-low frequency Pc5 and electromagnetic ion cyclotron waves, as measured by a Geostationary Operational Environmental Satellite (GOES), is higher during the sheath than during the ejecta. However, the level of chorus wave power, as measured by the Van Allen Probes, remains approximately the same due to similar substorm activity during the sheath and ejecta. Electron flux enhancements are common at low energies (<1 MeV) throughout the outer belt (L = 3–6), whereas depletion predominantly occurs at high energies for high radial distances (L>4). It is distinctive that the depletion extends to lower energies at larger distances. We suggest that this L-shell and energy-dependent depletion results from the magnetopause shadowing that dominates the losses at large distances, while the wave–particle interactions dominate closer to the Earth. We also show that non-geoeffective sheaths cause significant changes in the outer belt electron fluxes.

Published: June 2020

Abstract. A five-year greenhouse gas (GHG) exchange study of the three major gas species (CO2, CH4 and N2O) from an intensively managed permanent grassland in Switzerland is presented. Measurements comprise two years (2010/2011) of manual static chamber measurements of CH4 and N2O, five years of continuous eddy covariance (EC) measurements (CO2/H2O – 2010–2014) and three years (2012–2014) of EC measurement of CH4 and N2O. Intensive grassland management included both regular and sporadic management activities. Regular management practices encompassed mowing (3–5 cuts per year) with subsequent organic fertilizer amendments and occasional grazing whereas sporadic management activities comprised grazing or similar activities. The primary objective of our measurements was to compare pre-ploughing to post-ploughing GHG exchange and to identify potential memory effects of such a substantial disturbance on GHG exchange and carbon (C) and nitrogen (N) budgets. In order to include measurements carried with different observation techniques, we tested two different measurement techniques jointly in 2013, namely the manual static chamber approach and the eddy covariance technique, to quantify the GHG exchange from the observed grassland site. Our results showed that there were no memory effects on N2O and CH4 emissions after ploughing, whereas the CO2 uptake of the site considerably increased when compared to post-restoration years. In detail, we observed large losses of CO2 and N2O during the year of restoration. In contrast, the grassland acted as a carbon sink under usual management, i.e. the time periods (2010–2011 and 2013–2014). Enhanced emissions/emission peaks of N2O (defined as exceeding background emissions < 0.21 ± 0.55 nmol m−2s−1 (SE = 0.02) for at least two sequential days and the seven-day moving average exceeding background emissions) were observed for almost seven continuous months after restoration as well following organic fertilizer applications during all. Net ecosystem exchange of CO2 (NEECO2) showed a common pattern of increased uptake of CO2 in spring and reduced uptake in late fall. NEECO2 dropped to zero and became positive after each harvest event. Methane (CH4) exchange in contrast to N2O showed minor net uptake of methane seen by the static chambers and small net release of methane seen by the eddy covariance method. Overall, CH4 exchange was of negligible importance for both, the GHG budget as well as for the carbon budget of the site. Our results stress the inclusion of grassland restoration events when providing cumulative sums of C sequestration and/or global warming potentials (GWPs). Consequently, this study further highlights the need for continuous long-term GHG exchange observations as well as the implementation of our findings into biogeochemical process models to track potential GHG mitigation objectives as well as to predict future GHG emission scenarios reliably.
El verbo que dio nombre a la ontología. Una aproximación lingüística a la metafísica clásica
Authors: Alcocer Urueta Ricardo
Published: June 2020

Este artículo propone una aproximación lingüística a la ontología clásica y sugiere que el concepto griego de ‘ser’ fue determinado por las propiedades del verbo εἰμί. Por un lado, caracteriza esta palabra como un verbo estativo de soporte, léxicamente neutro y con aspecto imperfectivo. Por otro lado, relaciona semejante caracterización con la oposición filosófica entre la permanencia del ser y la transitoriedad del devenir, así como también con la expresión polisémica de lo ente.
Sobre las posibles referencias egipcias del Mito de las Edades de Hesíodo. Algunos documentos para el estudio de su génesis y estructura
Authors: Lazcano Vázquez Roque
Published: June 2020

En el presente artículo se explora la posibilidad de que las principales referencias no extranjeras del Mito de las cinco Edades-Razas de Hesíodo proviniesen de Egipto ‒aunque filtradas a través de la cultura minoica-micénica‒, y no, como por lo general se viene sosteniendo, de Mesopotamia. No se afirma que este mito, tal y como lo presenta Hesíodo, tuviese un homólogo previo en Egipto; solo se propone que algunos de los elementos que lo coordinan podrían inspirarse en tradiciones egipcias: particularmente, la idea de las cinco estirpes originarias (que Hesíodo historiza) y la distinción de los cuatro tipos de seres que las caracterizan. Contenidos similares se encuentran en Manetón (s. III a.C.), cuyos Αἰγυπτιακά se basaban en los registros mito-históricos transmitidos por las antiguas listas dinásticas, de las cuales el Canon Real de Turín (ca. s. XIII a.C.) es la mejor conservada. Guiados por este parecido, y apoyados en las reliquias que constatan el diálogo secular entre Grecia, Creta, Micenas y la región del Nilo, investigaremos otras tradiciones egipcias que pudieron influir en la elaboración del Mito de las Edades.

Authors: Rodrigues Melquizedec Arcos , MELO FILHO João de Almeida
Published: June 2020

RESUMO: O objetivo deste é determinar o percentual de substituição de cimento por resíduos de mármores/granitos (RMG) das marmorarias na fabricação de concreto autoadensável (CAA). A metodologia adotada foi a realização de vários ensaios laboratoriais: de caracterização; das propriedades reológicas, mecânicas, físicas e químicas do CAA. Foram aplicados dois superplastificantes,  sulfonado e polimérico. Os agregados foram caracterizados por ensaios de granulometria, massa específica; massa unitária em estado solto; e massa unitária em estado compactado. Os RMG foram submetidos a ensaio de massa específica e análise de Fluorescência de Raios X. Como ensaios reológicos foram realizados: Espalhamento, T500, Funil V e Caixa L; e Ensaios de Resistência à Compressão e à Flexão, Absorção, Índice de Vazios, Massa Específica e análise de Reação Álcali Agregado (RAA), no estado endurecido. Os resultados mostraram-se eficazes com até 30% de substituição do cimento por RMG. No estado fresco esse CAA atendeu aos requisitos da NBR 15823 (ABNT, 2010), se comportando como concreto adequado para utilização nas aplicações correntes. No estado endurecido apresentou resistência à compressão de 35 MPa e  resistência à flexão de 7,0 MPa, satisfazendo a NBR 15805 (ABNT, 2010), podendo também ser utilizado na produção de pavimentos de concreto e assim contribuindo para a redução de resíduos espalhados nas empresas, diminuição de danos ao meio ambiente  e trazendo economia para a obtenção de CAA.
ESTUDO DE VIABILIDADE ECONÔMICO-FINANCEIRA DA RECICLAGEM DE CONSTITUINTES DE RESÍDUOS DE CONSTRUÇÃO E DEMOLIÇÃO

Published: June 2020

RESUMO:  O objetivo deste trabalho consistiu em avaliar a viabilidade econômico-financeira de empreendimentos de construção e demolição realizarem a reciclagem de fragmentos de concreto e cerâmica. Para tal, foram projetados quatro cenários econômicos considerando construtoras responsáveis pela geração de diferentes quantidades de resíduos de construção e demolição (RCD’s), nos quais foi orçada uma britadeira móvel para a reciclagem do material. Os custos relacionados à aquisição, operação e manutenção da britadeira, foram confrontados em fluxos de caixa, com as receitas provenientes do uso ou venda do material reciclado na forma de brita n° 0, bem como da economia com caçambas de entulhos. Posteriormente, a rentabilidade dos projetos foi avaliada mediante o fator de recuperação do capital, o valor presente líquido e a taxa interna de retorno. Quanto maior a produção de RCD’s, maior também é a relação custo-benefício da aquisição da britadeira e, em função da maior quantidade de brita n° 0 reciclada (passível de ser utilizada na produção de contrapiso ou comercializada) e da maior economia com caçamba de entulhos, maiores são as receitas adquiridas, menor é o período de retorno do capital investido e maior é a rentabilidade financeira dos cenários projetados. A reciclagem de RCD’s além de proporcionar benefícios ambientais, pode ser um investimento financeiramente atrativo.

ABSTRACT: The objective of this work was to evaluate the economic and financial feasibility of construction and demolition projects to carry out the recycling of concrete and ceramic fragments. For this, four economic scenarios were designed considering constructors responsible for the generation of different amounts of construction and demolition waste (RCD's), in which a mobile squeegee was used to recycle the material. The costs related to the acquisition, operation and maintenance of the crushing machine were compared to cash flows, with revenues from the use or sale of recycled material in the form of gravel No. 0, as well as the economy with litter bins. Subsequently, the profitability of the projects was evaluated by the capital recovery factor, the net present value and the internal rate of return. The higher the production of RCD’s, the greater the cost-benefit ratio of the purchase of the crushing machine and, due to the greater quantity of recycled crushed stone (which can be used in the production of sub-floor or commercialized) and the largest economy with a bucket of debris, the higher are the revenues acquired, the lower the return period of invested capital and the greater the financial profitability of the projected scenarios. Recycling RCD’s in addition to providing environmental benefits can be a financially attractive investment.

Les Boni sont aujourd’hui regardés comme le seul peuple marron rattaché à la France. L’article retrace les étapes qui ont abouti à cette situation. Massacrés par les Marrons Ndjuka, alliés des Néerlandais, en 1793, les Boni ne concluent pas de traité de paix avec les Pays-Bas par la suite : ils sont placés sous une sorte de « tutelle » des Ndjuka reconnue tant par les Néerlandais que par les Français. En 1860, avec les abolitions de l’esclavage, les Boni se voient reconnaître leur liberté par les deux puissances coloniales. Progressivement, à partir de 1880 et en raison d’un litige frontalier entre la France et les Pays-Bas, les Boni nouent un lien avec la France, confirmé en 1892.

Published: June 2020

Gastroenteric viruses are important pathogens related to cases of acute gastroenteritis, affecting millions of people worldwide with a major impact on children under five in developing countries. The introduction of metagenomic approach techniques in the 2000s has allowed the description of new viruses, among them Salivirus, which has been associated worldwide with cases of diarrhea. This study aimed to detect salivirus in raw sewage samples from a wastewater treatment plant (WWTP) collected between June 2013 and May 2014 in Rio de Janeiro, Brazil. Fifty-two samples collected weekly were tested by using a real-time quantitative PCR (qPCR).  Salivirus genome was detected in 71.1% (37/52) of the samples, with viral concentration ranging from 7.56 x 104 to 7.20 x 106 genomic copies per liter. Higher viral loads were detected in the summer and fall of 2014, although these data were not sufficient to infer seasonality for this virus. The high prevalence of salivirus in sewage samples highlights the importance of viral research in wastewater to generate data on salivirus circulation, increasing understanding regarding its dissemination in the population.KEY WORDS: Wastewater; viral detection; salivirus; Brazil; raw sewage; qPCR.

Null/overt subject alternations in L2 Spanish and L2 Greek
Authors: Margaza Panagiota , Gavarró Anna
Published: June 2020

This study aims at exploring the omission/expression of subjects in L2 Spanish and L2 Greek. The distribution of subjects is examined in the context of the Interface Hypothesis (IH), which locates the difficulty of acquisition at the syntax-pragmatics interface (Sorace & Filiaci 2006; Tsimpli & Sorace 2006) and the language combination examined is a case in point as both languages share the null subject property and yet the IH predicts delay in L2 acquisition. We also examine the predictions of Lozano’s (2016) Pragmatic Principles Violation Hypothesis. We designed two multiple-choice tasks, one in Spanish and one in Greek, testing subjects in various pragmatic contexts. The tasks were administered to L2 intermediate and advanced learners and native speakers of Spanish and Greek. The results obtained indicate that the L2 learners were able to select the felicitous type of subjects in the appropriate contexts, although they did not always achieve native-like patterns. An asymmetry arose between L2 Greek and L2 Spanish, as L2 Greek was native-like, an asymmetry that failed to be predicted by any of the hypotheses entertained. Even though the involvement of the interface levels might have affected L2 performance, the syntax-pragmatics interface was not consistently having a detrimental effect on the results. Furthermore, our results with the control group indicated that the subject distribution in adult Greek is more nuanced than reported in the literature, especially in unambiguous referent-shift contexts.
Finding (One)self in Art Education: A Queer Conversation
Authors: Bradshaw Darden , Ria
Published: June 2020

This article, a two-person narrative, makes visible some challenges embedded in queering pre-service art education in an educational sphere that tends to be seen as heteronormative, White, able-bodied, and cisgendered—even for those who are queer themselves. In this piece, Ria, an undergraduate student, offers the reader a peek into a lived experience rarely shared as they describe the challenge of finding themselves at university, navigating the repeated coming out process both in and outside the classroom, undergoing treatment for cancer, and returning a changed person. The co-narrative offers the perspective of Ria’s university faculty member and mentor. Acknowledging moments of awareness and dissonance, she discusses the journey to rectify curriculum and pedagogy in a responsive manner while noting the value of being present for one’s student beyond the walls of the classroom. Ria’s comic book images are the vehicle through which life, grief, and moving forward are explored.
Queer Up! Application of Queer Representation in Art Education
Authors: Yang Meng-Jung , Hsieh Kevin
Published: June 2020

Gender representation is inherently a part of child-oriented media that plays a significant role in childhood identity development, and the lack of positive queer representation may lead to unfair treatment of queer youth. An art classroom cannot be a space for exploration and risk-taking if art teachers are unaware of how to structure an appropriate environment for queer curricula. Recognizing the circumstances, we categorize queer representations in media as queer main-text and queer subtext. (Queer representation can be utilized as a foundational approach for cultivating pre-service art teachers’ visual literacy regarding two aspects: (1) the sensibility of decoding visual spectacles of queer representations, and (2) the actions of encoding visual messages for educational application. With a mind-set of advocating for diversity, pre-service art teachers can critically and logically refute normative interpretations of LGBTQ+ representations in media, create a space for open exploration of LGBTQ+, and reveal and neutralize top-down power relationships within K—12 art classrooms. Further, pre-service art teachers will be better primed to take on a leading role in advocating for LGBTQ+ themes, and they will be encouraged to create an appropriate place for queer students to feel welcome to express themselves, but also a place where students can experience open-mindedness and empathetically embrace diversity.
Redefining Controversy and Outness: Honest Queer Art Education in the South
Authors: Manning Madison
Published: June 2020

In this paper, I discuss my experience as an out lesbian art professor and offer my view into the future of queer art education. After a year of teaching at a southeastern private Christian university, I’ve developed strategies for integrating queer art history even in the least accepting of institutions. Throughout the narrative, I use three of my own pieces to illustrate the intersection of my art practice, my pedagogy, and my experience as a queer womxn. Ultimately, by framing queer art history as a crucial component of art history, I argue that it is our job as educators to teach our students rich, complicated histories of art so they are able to place themselves as artists but also as human beings within that history.
The “Day After” Covid-19 Pandemic: Logistical Disorders in Perspective
Authors: Paché Gilles
Published: June 2020

Half of humanity experienced an unprecedented situation of lockdown during the Covid-19 pandemic of 2020. The sharp slowdown in trade and the shutdown of entire industrial and commercial sectors had major economic consequences, with a historic collapse in household consumption, particularly in Europe. One country after another decided to gradually organize a lockdown exit, taking into account the heavy health constraints involved. This lockdown exit, and the resulting boom of trade, is likely to come up against a major disruption of supply chains, which needs to be evaluated now. The research note proposes an exploratory reflection on a unique situation since the WW II, and the logistical implications of what can be called the “day after” the Covid-19 pandemic. In order to limit serious disorders in product flow monitoring, the question of a moderate rhythm of lockdown exit and economic recovery is raised.

Steering tourism gentrification in the urban centre: lessons from the city streets of Amsterdam

The extensive growth of urban tourism has influenced the living environment of urban citizens worldwide, which is among others due to changes in the range of commercial amenities. As a manifestation of this development, the existing supply of retail and hospitality services gradually changes from a focus on inhabitants to the tourist. As a result, the call for municipal intervention grows. However, little is known about the steerability of this development. In this article we therefore asses how tourism affects the range of commercial amenities in city streets, and what local policy responses are most suitable. The research builds on the concepts of tourism gentrification and different types of ‘policy-instrument fit’. Our case study of the city centre of Amsterdam, including a media and policy document analysis, as well as in-depth interviews with stakeholders, show that some problems caused by mass tourism require ‘hard’ forms of government control, while others require a ‘softer’ process approach, linking local parties to jointly improve a city street. The presented steering perspectives are not only relevant for the city of Amsterdam, but also for many other towns within, and beyond, the Netherlands, that have been struggling with the growth of tourism. The open attitude towards urban mass tourism has come up for discussion and urban (tourism) policy calls for reconsideration.

De procesinleiding; het goede moment voor regie

De door de minister beoogde procesinleiding dreigt het aantal betekeningen sterk te verhogen. Verder blijven zijn voorstellen binnen de vertrouwde kaders; veel mogelijkheden van de moderne techniek worden onbenut gelaten.

Retail trade involves constant changes and trends due to influence of marketing promotions on traders themselves and their customers as well. This is an internal environment of a retail store, which is a part of factors that define customer’s buying decision. In general, more than 80% of buyers make a buying decision on the spot or the last place where buyers normally can change their mind to make a purchase. A customer’s final decision to make a purchase is affected not only by the cost of the item but also the means of marketing promotion and visual aspect of goods. Therefore, it is necessary to constantly collect factual information based on customers’ feedback on effectiveness and efficiency of these marketing promotions in real-store environment. Recent trends of marketing research development demand a wide use of research methods in conducting in-store research based on new technologies besides the traditional ones. Optimal use of new methods of neuromarketing gives more opportunity to develop efficient marketing strategy and to provoke customers’ interest and emotions as well. Techniques to stimulate customer’s interest and emotions can help increase their motivation to make a purchase followed by increase in s store’s sales and profit. In this study we have used a methodology based in neuromarketing technology to identify factors affecting customer’s visual attention and emotions in a grocery store. The study was conducted in real environment of a retail grocery store using a mobile eye camera (Eye tracker), mobile electroencephalograph (EEG), face reading technology (FA) and internal position system. The objective of the study is to identify customers’ reaction, emotions and feedback using selected neuromarketing methods in a store. At the end of the research, we have identified how neuromarketing techniques can be applied in better understanding customer behavior at a point of sale.

This paper proposes an assessment of the links between freight trip generation (FTG) rates and accessibility. First, the paper overviews the background, sets the context and motivates the research. Second, it presents the proposed methodology, which combines an FTG model, two accessibility indicators and a linear regression analysis to assess the relationships between freight trip demand and a set of socio-demographic variables including accessibility. The FTG modelling framework, adapted from previous works, allows estimating the number of freight trips with a small amount of standard data, even when no surveyed data is available. The two gravity accessibility indexes, one potential and one exponential, are defined in the continuity of recent freight accessibility works. To those indicators, a set of socio-demographic variables, including population, area or a zone (or density), are introduced. The relationships between FTG and all those variables are assessed via standard linear regression methods completed by the verification of the corresponding linear relationship hypotheses. Third, the framework is applied to the urban area of Lyon (France), where no urban goods survey data is available. Results show that potential accessibility seems to have a better correlation to FTG and could be a good decision support indicator when combined with the population as an explanatory variable. The population can be added to accessibility as an explanatory variable, the resulting models with two variables have a slightly lower accuracy but remains close to that of models with only accessibility as an explanatory variable. This work remains exploratory and finishes by proposing practical implications and further development lines.

Currently, air pollution and energy consumption are the main issues in the transportation area in large urban cities. In these cities, most people choose their transportation mode according to corresponding utility including traveller's and trip’s characteristics. Also, there is no effective solution in terms of population growth, urban space, and transportation demands, so it is essential to optimize systematically travel demands in the real network of roads in urban areas, especially in congested areas. Travel Demand Management (TDM) is one of the well-known ways to solve these problems. TDM defined as a strategy that aims to maximize the efficiency of the urban transport system by granting certain privileges for public transportation modes, Enforcement on the private car traffic prohibition in specific places or times, increase in the cost of using certain facilities like parking in congested areas. Network pricing is one of the most effective methods of managing transportation demands for reducing traffic and controlling air pollution especially in the crowded parts of downtown. A little paper may exist that optimize urban transportations in busy parts of cities with combined Markov decision making processes with reward and evolutionary-based algorithms and simultaneously considering customers’ and trip’s characteristics. Therefore, we present a new network traffic management for urban cities that optimizes a multi-objective function that related to the expected value of the Markov decision system’s reward using the Genetic Algorithm. The planned Shiraz city is taken as a benchmark for evaluating the performance of the proposed approach. At first, an analysis is also performed on the impact of the toll levels on the variation of the user and operator cost components, respectively. After choosing suitable values for the network parameters, simulation of the Markov decision process and GA is dynamically performed, then the optimal decision for the Markov decision process in terms of total reward is obtained. The results illustrate that the proposed cordon pricing has significant improvement in performance for all seasons including spring, autumn, and winter.
Where and when do drivers speed? A feasibility study of using probe vehicle data for speeding analysis

Published: June 2020

Speed is a critical transportation concept – it is one of the most important factors that road users consider in relation to route convenience and efficiency; at the same time speed has been recognized as the most influential risk factor. To improve speeding analyses, an emerging data source – probe vehicle data (also known as floating car data), may be used. This data enables obtaining information on vehicle speeds, without being limited in time and space.
To prove the feasibility of using this data, a study was conducted on a sample of Prague expressway and collector roads. Firstly, probe data sample validity was checked through comparison to a traditional speed measurement technique – average speed control. Secondly, descriptive analysis of speeding was performed, focusing on speeding differences across homogeneous road segments in individual hour intervals. Thirdly, statistical models were also developed to explain which road parameters contribute to speeding. Analysis utilized cross-section and geometry parameters, which may potentially be related to speed choice and driving speed and speeding.
In general, the applied concept proved as feasible: particularly night time was found more prone to speeding, and the rates were significantly different between segments. Statistical models indicated the statistically significant influence on speeding: lower speed limit, lower number of lanes, absence of roadside activities, or presence of horizontal curves. Information on these factors may be generalized and used for planning adequate speeding countermeasures. Final discussion also identified and described several challenges for future research, including free-flow speed estimation uncertainty, quality of speed-safety models, and potential multicollinearity of explanatory variables.
Das Recht auf soziale Sicherung nach der VN Behindertenrechtskonvention und dessen Implementierung in Uganda und Ghana
Authors: Groß Lukas
Published: June 2020

‘Disability may increase the risk of poverty, and poverty may increase the risk of disability.’ Breaking this cycle is a major challenge for the international community, especially the countries of the Global South. As the most recent human rights treaty of the United Nations, the UN Convention on the Rights of Persons with Disabilities also specifies the right to social protection. This study deals with the question of to what extent a human rights-based approach characterised by need orientation and accessibility can be derived from specific state obligations. In addition, it examines the efforts to implement such an approach in Sub-Saharan Africa. In this context, the study shows that it has been possible to both develop innovative concepts that consider the realities of the lives of local people with disabilities in Uganda and Ghana and, at the same time, to ensure the implementation of international human rights law in those two countries.

Background: Nowadays, complicated and painful surgical procedures are encouraged to be carried out in an ambulatory setting. Objectives: The current study aimed to assess 4-week postoperative pain profiles of 4 painful ambulatory surgical procedures. We analyzed the prevalence of and reasons for non-adherence and partial adherence of patients to a predefined treatment schedule after the ambulant surgery. Methods: The current study analyzed data from a large randomized trial by evaluating the effect of postoperative pain medication on acute postoperative pain at home during the first 4 postoperative days (POD) in patients scheduled for ambulatory hemorrhoid surgery, shoulder or knee arthroscopy, and inguinal hernia repair. Postoperative pain intensity was assessed at POD 0, 1, 2, 3, 4, 7, 14, and 28 via the Numeric Rating Scale (NRS). Adherence was assessed on POD 1, 2, 3, and 4. Results: Median average pain scores were above an NRS of 3 during the first postoperative week after shoulder arthroscopy and even above 4 during the first postoperative week after hemorrhoid surgery. 26% of patients undergoing shoulder arthroscopy and hemorrhoid surgery still had moderate pain 1 week after surgery. Median average pain scores were below an NRS of 3 during the whole study period after inguinal hernia repair and knee arthroscopy. 24.61% of patients did not use the study medication as prescribed, 5.76% of whom were non-adherent, and 18.85% were partially adherent. Conclusions: Each type of ambulant surgery has its unique postoperative pain profile. New strategies should be developed for pain therapy at home, particularly after the ambulatory arthroscopic shoulder surgery and hemorrhoid surgery. Non-adherence is uncommon if they are provided with a multimodal analgesic home kit together with clear verbal, written instructions, and intensive follow-up.
