Published: October 2019

Abstract. The World Meteorological Organization (WMO) Solid Precipitation Inter-Comparison Experiment (SPICE) involved extensive field intercomparisons of automated instruments for measuring snow during the 2013/2014 and 2014/2015 winter seasons. A key outcome of SPICE was the development of transfer functions for the wind bias adjustment of solid precipitation measurements using various precipitation gauge and windshield configurations. Due to the short intercomparison period, the dataset was not sufficiently large to develop and evaluate transfer functions using independent precipitation measurements. The present analysis uses data collected at eight SPICE sites over the 2015/2016 and 2016/2017 winter periods, comparing 30-minute adjusted and unadjusted measurements from Geonor T-200B3 and OTT Pluvio2 precipitation gauges in different shield configurations to the WMO Double Fence Automated Reference (DFAR) for the verification of the transfer function. Performance is assessed in terms of relative total catch (RTC), root mean square error (RMSE), and Pearson correlation (r), and Nash-Sutcliffe Efficiency (NSE) for all precipitation types, and for snow only. The evaluation shows that the performance varies substantially by site. Adjusted RTC varies from 54 % to 123 %, RMSE from 0.07 mm to 0.38 mm, and r from 0.28 to 0.94 and NSE from −1.88 to 0.89, depending on precipitation phase, site, and gauge configuration. Generally, windier sites such as Haukeliseter (Norway) and Bratt's Lake (Canada) exhibit a net under-adjustment (17 % to 46 %), while the less windy sites such as Sodankylä (Finland) and Caribou Creek (Canada) exhibit a net over-adjustment (2 % to 23 %). Although the application of transfer functions is necessary to mitigate wind bias in solid precipitation measurements, especially at windy sites and for unshielded gauges, the inconsistency in the performance metrics among sites suggests that the functions be applied with caution.
Coupled machine learning and the limits of acceptability approach applied in parameter identification for a distributed hydrological model

Published: October 2019

Abstract. Monte Carlo (MC) methods have been widely used in uncertainty analysis and parameter identification for hydrological models. The main challenge with these approaches is, however, the prohibitive number of model runs required to get an adequate sample size which may take from days to months especially when the simulations are run in distributed mode. In the past, emulators have been used to minimize the computational burden of the MC simulation through direct estimation of the residual based response surfaces. Here, we apply emulators of MC simulation in parameter identification for a distributed conceptual hydrological model using two likelihood measures, i.e. the absolute bias of model predictions (Score) and another based on the time relaxed limits of acceptability concept (pLoA). Three machine learning models (MLMs) were built using model parameter sets and response surfaces with limited number of model realizations (4000). The developed MLMs were applied to predict pLoA and Score for a large set of model parameters (95 000). The behavioural parameter sets were identified using a time relaxed limits of acceptability approach based on the predicted pLoA values; and applied to estimate the quantile streamflow predictions weighted by their respective Score. The three MLMs were able to adequately mimic the response surfaces directly estimated from MC simulations; and the models identified using the coupled ML emulators and the limits of acceptability approach have performed very well in reproducing the median streamflow prediction both during the calibration and validation periods.
Inferred inflow forecast horizons guiding reservoir release decisions
across the United States
Authors: Turner Sean W. D. , Xu Wenwei , Voisin Nathalie
Published: October 2019

Abstract. Medium to long-range forecasts often guide reservoir release decisions to support water management objectives, including mitigating flood and drought risks. While there is a burgeoning field of science targeted at improving forecast products and associated decision support models, data describing how and when forecasts are applied in practice remains undeveloped. This lack of knowledge may prevent hydrological modelers from developing accurate reservoir release schemes for large-scale, distributed hydrology models that are increasingly used to assess the vulnerabilities of large regions to hydrological stress. We address this issue by estimating seasonally-varying, regulated inflow forecast horizons used in the operations of more than 300 dams throughout the Conterminous United States. For each dam, we take actual forward observed inflows (perfect foresight) as a proxy for forecasted flows available to the operator, and then identify for each week of the year the forward horizon that best explains the release decisions taken. Resulting horizon curves specify for each dam the inferred horizon as a function of the week of the water year. These curves are analyzed for strength of evidence for contribution of medium to long-range forecasts in decision making. We use random forest classification to estimate that approximately 80 % of large dams and reservoirs in the US (1553 ± 50 out of 1927 dams with at least 10 Mm3 storage capacity) adopt medium to long-range inflow forecasts to inform release decisions during at least part of the water year. Long-range forecast horizons (more than six weeks ahead) are detected in the operations of reservoirs located in high elevation regions of the Western US, where snowpack information likely guides the release. A simulation exercise conducted on a selection of key reservoirs demonstrates that forecast-informed models of reservoir operations outperform models that neglect the horizon curve – including during flood and drought conditions.
On the Conceptual Complexity of Non-Point Source Management:
Impact of Spatial Variability
Authors: Henri Christopher Vincent , Harter Thomas , Diamantopoulos Efstathios
Published: October 2019

Abstract. Non-point source (NPS) pollution has degraded groundwater quality of unconsolidated sedimentary basins over many decades. Properly conceptualizing NPS pollution from the well scale to the regional scale leads to complex and expensive numerical models: Key controlling factors of NPS pollution – recharge rate, leakage of pollutants, and soil and aquifer hydraulic properties – are spatially and, for recharge and pollutant leakage, temporally variable. This leads to high uncertainty in predicting well pollution. On the other hand, concentration levels of some key NPS contaminants (salinity, nitrate) vary within a limited range (
On the sensitivity of meteorological forcing resolution on hydrologic metrics
Authors: Maina Fadji Z. , Siirila-Woodburn Erica R. , Vahmani Pouya
Published: October 2019

Abstract. Projecting the spatio-temporal changes to water resources under a no-analog future climate requires physically-based integrated hydrologic models, which simulate the transfer of water and energy across the earth's surface. These models show promise in the context of unprecedented climate extremes given their reliance on the underlying physics of the system as opposed to empirical relationships. However, these techniques are plagued by several sources of uncertainty, including the inaccuracy of input datasets such as meteorological forcing. These datasets, usually derived from climate models or satellite-based products, typically have a resolution of several kilometers, while hydrologic metrics of interest (e.g. discharge, groundwater levels) require a resolution at much smaller scales. In this work, a high-resolution watershed model is forced with various resolutions (0.5 to 40.5 km) of meteorological forcing generated by a dynamical downscaling analysis based on a regional climate model (WRF) to assess how the uncertainties associated with the spatial resolution of meteorological forcing affect the simulated hydrology. The Cosumnes watershed, which spans the Sierra Nevada and Central Valley interface of California (USA), exhibits semi-natural flow conditions due to its rare un-dammed river basin and is used here as a testbed to illustrate potential impacts on snow accumulation and snowmelt, surface runoff, infiltration, evapotranspiration, and groundwater levels. Results show that localized biases in groundwater levels can be as large as 5–10 m and that other metric biases (e.g. ET and snowpack dynamics) are seasonally and spatially-dependent, but can have serious implications for model calibration and ultimately water management decisions.

Published: October 2019

Abstract. The growth of Indonesia‟s national economy in the sector of tourism has been improving constantly. Based on BPS data year 2015, tourism has contributed to PDB with the amount of 4,25%. Tourists is an important aspect because they play a role in the economic change in tourism. Along with social media development, tourists‟ distribution can be monitored using big data in social media. Instagram is one of the social media which is often used by tourists to share photos or videos while traveling. Issues that appeared when using big data Instagram to produce spatial data are size, variation, and a big time span. This research is aimed to extract big data Instagram to produce basic tourists’ spatial data and analyze tourist attractions using geovisualization hexagonal tessellation in West Java Province and Special Region of Yogyakarta. Generally, the methods used are divided into three which are data mining, graphic visual analysis and geovisualization classification hexagonal tessellation. The Instagram data extraction process uses a web-based software called Netlytic, while pre-processing data to produce tourists’ spatial data uses QGIS software. Hexagonal tessellation is tested by graphic visual to ensure the most effective measurement in the scale of 1 : 1.250.000. The most effective hexagonal tessellation measurement is used to classify tourist attractions. Based on the results, it shows that the most effective measurement of hexagonal tessellation is 2 Km. The most popular tourist attraction is Malioboro Yogyakarta based on hexagonal tessellation geovisualization analysis.
A spatial decision support system for enhancing resilience to floods.
Bridging resilience modeling and geovisualization techniques
Authors: Heinzlef Charlotte , Becue Vincent , Serre Damien
Published: October 2019

Abstract. In the context of climate change and increasing urbanization, floods are considerably affecting urban areas. The concept of urban resilience may be an interesting means of responding to urban flood issues. The objective of this research is to propose a spatial decision support tool based on geovisualization techniques and a resilience assessment method. The goal is to localize the level of resilience modeled in different territories. The methodology proposed consists in integrating three resilience indicators applied to a case study in Avignon (Provence Alpes Côte d'Azur Region, France) and the use of geovisualization techniques: using GIS for data processing and analysis, visualization, mapping and model processing. The methodology integrates decision-making by identifying characteristics capable of improving urban resilience and facilitating its understanding using a visual tool. The results demonstrate the usefulness of modeling resilience using geovisualization techniques to identify the potential for local resilience, integrate local stakeholders into a process of clarifying the concept through the contribution of visualization, and consider easier access to this concept based on data analysis, processing and visualization through the design of maps.
Assessment of ocean analysis and forecast from an atmosphere–ocean coupled data assimilation operational system

Published: October 2019

Abstract. The development of coupled atmosphere–ocean prediction systems with utility on short-range numerical weather prediction (NWP) and ocean forecasting timescales has accelerated over the last decade. This builds on a body of evidence showing the benefit, particularly for weather forecasting, of more correctly representing the feedbacks between the surface ocean and atmosphere. It prepares the way for more unified prediction systems with the capability of providing consistent surface meteorology, wave and surface ocean products to users for whom this is important. Here we describe a coupled ocean–atmosphere system, with weakly coupled data assimilation, which was operationalised at the Met Office as part of the Copernicus Marine Environment Service (CMEMS). We compare the ocean performance to that of an equivalent ocean-only system run at the Met Office and other CMEMS products. Sea surface temperatures in particular are shown to verify better than in the ocean-only systems, although other aspects including temperature profiles and surface currents are slightly degraded. We then discuss the plans to improve the current system in future as part of the development of a “coupled NWP” system at the Met Office.
Deciphering the metamorphic evolution of the Pulo do Lobo metasedimentary belt (SW Iberian Variscides)

Published: October 2019

Abstract. The Pulo do Lobo belt is one of the units related to the orogenic suture between the Ossa-Morena and the South Portuguese zones in the SW Iberian Variscides. This metasedimentary unit has been classically interpreted as a Rheic subduction-related accretionary prism formed during the pre-Carboniferous convergence and eventual collision between the South Portuguese Zone (part of Avalonia) and the Ossa-Morena Zone (peri-Gondwanan terrane). Discrete mafic intrusions also occur in the dominant Pulo do Lobo metapelites, related to an intraorogenic Mississippian transtensional and magmatic event that had a significant thermal input. Three different approaches have been applied to the Devonian/Carboniferous phyllites and slates of the Pulo do Lobo belt in order to study their poorly known low-grade metamorphic evolution. X-Ray diffraction (XRD) was used to unravel the mineralogy and measure crystallographic parameters (illite crystallinity and K-white mica b-cell dimension). Compositional maps of selected samples were obtained from electron probe microanalysis, which allowed processing with XmapTools software, and chlorite semi-empirical and thermodynamic geothermometry was performed. Thermometry based on Raman spectroscopy of carbonaceous material (RSCM) was used to obtain peak temperatures. The microstructural study shows the existence of two phyllosilicate growth events at the chlorite zone, the main one (M1) related to the development of a Devonian foliation S1, and a minor one (M2) associated with a crenulation cleavage (S2) developed at middle/upper Carboniferous time. M1 entered well into epizone (greenschist facies) conditions. M2 conditions were at lower temperature, reaching the anchizone/epizone boundary. These data accord well with the unconformity that separates the Devonian and Carboniferous formations of the Pulo do Lobo belt. The varied results obtained by the different approaches followed, combined with microstructural analysis, are indicative of different snapshots of the metamorphic history. Thus, RSCM temperatures are higher in comparison with the other methods applied, which is interpreted as reflecting a faster reequilibration during the short-lived thermal Mississippian event. Regarding the metamorphic pressure, the data are very homogeneous (very low celadonite content in muscovite and low values of K-white mica b-cell dimension), indicating a low-pressure gradient, which is unexpected in a subduction-related accretionary prism.
Development and feasibility study of segment blade test methodology
Authors: Ha Kwangtae , Bätge Moritz , Melcher David , Czichon Steffen
Published: October 2019

Abstract. This paper outlines a novel segment test methodology for wind turbine rotor blades. The segment test mainly aims at improving the efficiency of the fatigue test as a future test method at Fraunhofer IWES. While resulting in reduced testing times, target fatigue bending moments over the intended test area have to be matched within an acceptable range of overload. The numerical simulation reveals that the proposed segment testing has a significant time saving up to 43 % and 53 % for 60 m and 90 m blades. When compared to the experimental data of 60 m full-length blade fatigue test, the proposed methodology also shows better test quality over the intended area and better certifiable regions over the outboard area.

Growth performance and meat composition of rabbits fed diets supplemented with silkworm pupae meal
Authors: Gugołek Andrzej , Strychalski Janusz , Kowalska Dorota
Published: October 2019

Aim of study: To determine the effect of different dietary levels of silkworm pupae meal (SWPM) on the growth performance of broiler rabbits and the chemical composition of their meat.Area of study: Southern Poland, Europe.Material and methods: Ninety Termond White rabbits were divided into three feeding groups. Control group rabbits were fed a diet containing 10% soybean meal (SBM). In the first experimental group, rabbits received a diet containing 5% SBM and 5% SWPM. The diet administered to the second experimental group was supplemented with 10% SWPM.Main results: Both partial and complete replacement of SBM with SWPM in diets contributed to a decrease in the final body weights of rabbits (2416.50 and 2390.78 vs. 2616.78 g), average daily gains (30.23 and 30.52 vs. 33.12 g) and feed intake (5.61 and 5.15 vs. 6.51 kg), but it improved the feed conversion ratio (3.28 and 3.05 vs. 3.41 kg/kg). Rabbits fed diets supplemented with SWPM were characterized by lower values of selected carcass parameters such as carcass weight and dressing percentage. Experimental diets had no significant effect on the proximate chemical composition of meat, but they increased the levels of fatty acids C18:3, C22:5 and C22:6.Research highlights: The results of this study can be put into practice to replace conventional protein and fat sources in rabbit diets with insect meals (SWPM) in the production of rabbit meat for human consumption. Our findings can also contribute to the recycling of sericultural waste.
A sinusoidal equation as alternative to conventional growth functions to describe the evolution of growth in quail
Authors: Darmani-Kuhi Hassan , France James , López Secundino , Ghavi Hossein-Zadeh Navid
Published: October 2019

Aim of study: The aim of the present study was to introduce a sinusoidal equation into poultry science by applying it to temporal growth data from quail.Material and methods: To examine the performance of the sinusoidal equation in describing the growth patterns of quail, four conventional growth functions (Gompertz, logistic, López and Richards) were used as reference in this study. Comparison of models was carried out by analysing model behaviour when fitting the curves using nonlinear regression and assessing statistical performance. Maximum log-likelihood estimation, mean squared error, Akaike and Bayesian information criteria were used to evaluate the general goodness-of-fit of each model to the different data profiles.Main results: The selected sinusoidal equation precisely describes the growth dynamics of quail. Comparison of the growth functions in terms of the goodness-of-fit criteria revealed that the sinusoidal equation was one of the most appropriate functions to describe the age-related changes of bodyweight in quail.Research highlights: To the best of our knowledge there are no studies available on the use of sinusoidal equations to describe the evolution of growth in quail. The sinusoidal equation used in this study represents a suitable alternative to conventional growth functions to describe the growth curves for a range of strains/lines of male and female Japanese quail.

Published: October 2019

O presente artigo é um estudo empírico, realizado por meio da revisão da literatura, que pretende i) investigar e descobrir a possível relação entre a taxa básica de juros Selic e o Imposto sobre Produtos Industrializados (IPI) sobre a Produção Industrial; ii) responder às crescentes discussões sobre a efetividade de diferentes medidas do governo inclusive a redução do IPI, visando estimular a competitividade do setor industrial do país; iii) verificar a possível influência da política monetária do governo para o controle da inflação por meio da subida da taxa de juros sobre a variável econômica da produção industrial. Por se tratar de três variáveis de pesquisa, utilizou-se o modelo de Vetores autorregressivos (VAR), analisando como a produção industrial responde a choques na variação das taxas Selic e IPI. Foi verificado, que a produção industrial reage tanto às variações na taxa Selic quanto ao IPI. Esse, por sua vez, reage a choques na taxa Selic, o que acaba por  refletir no comportamento da produção industrial.

Published: October 2019

Comumente as empresas elaboram os fluxos de caixa com projeções limitadas ao horizonte de tempo que assegurem um planejamento financeiro plausível. Contudo, estas projeções não permitem contemporizar tomadas de decisões que possam ser essenciais para a constância no mercado. Uma maneira para contornar esta deficiência, que é inerente aos projetos de investimentos em ativos reais, é a adoção de modelos dinâmicos que permitam flexibilizar o gerenciamento destes projetos. Diante disso, a Teoria das Opções Reais foi utilizada para avaliar os investimentos de capital de um projeto destinado ao processamento de laranja com a possibilidade de alteração da escala operacional. Os resultados demonstraram que a aplicação da Teoria das Opções Reais permitiu quantificar o valor adicional do projeto de investimentos aumentando o valor da indústria em 67%.

Assim, para que sejam evitados desperdícios e, a fim de assegurar um melhor desempenho dos processos produtivos, métodos como o Seis Sigma são utilizados, para que sejam identificadas as principais perdas produtivas, eliminando desperdícios. O presente trabalho tem por objetivo implantar a ferramenta Seis Sigma para identificar e eliminar o desperdício de soja na transferência entre o graneleiro e a fábrica de uma cooperativa agroindustrial. Foi utilizada a metodologia Six Sigma, tendo como base a ferramenta DMAIC (Define, Measure, Analyse, Improve, Control) para mensurar e analisar as principais perdas do processo, propondo melhorias e soluções para minimizar os desperdícios encontrados no processo de recebimento, armazenamento e transporte do grão de soja, do setor do graneleiro para o setor de extração de óleo. A grande contribuição do projeto Seis Sigma foi a análise e, consequentemente, o conhecimento do processo de transferência da soja, e de cada etapa produtiva. Através deste projeto, observou-se grande envolvimento dos funcionários, os quais contribuíram nas diversas etapas realizadas em que buscaram a melhoria e maior conhecimento de todas as etapas ali presentes, bem como o estabelecimento de padrões nas atividades.
Pupils’ access to inappropriate web content: the example of primary schools in Slupsk
Authors: Kosznik-Biernacka Sylwia
Published: October 2019

The publication is a summary of the pilot studies carried out by Comdrev.PL company, a provider of a service named PROTECTI, from February to April 2018 in four primary schools in Slupsk. The study’s objective was to monitor pupils’ online activities while at school and using the school network. The author made a hypothesis that primary school pupils, while at school, do visit inappropriate websites. The analysis of the visited pages, based on the thematic catalogue by Comdrew.PL, shown that inappropriate content has indeed been accessed. The scale of the phenomenon turned out to be worrying, thus, as early as within the study duration, school authorities decided to take countermeasures by blocking access to inappropriate content. Therefore, the analysis included both the inappropriate content that the pupils actually viewed from February to April 2018 and the content they wanted to visit at that time but access to it was blocked. The fundamental conclusion of the research is that it is necessary to filter the content available in the school network and to block access to the inappropriate content so as to ensure the proper realization of the school’s educational tasks.
Immunitet parlamentarny we współczesnym świecie – ujęcie prawnoporównawcze
Authors: Jackiewicz Andrzej
Published: October 2019

The purpose of the article is to determine the current form of parliamentary immunity in various countries. The author uses the comparative-law method to analyse constitutions that represent the most common solutions, taking into account the geographic criterion, used in countries located on different continents and having different legal cultures. The author analyses the subjective scope of non-accountability and non-violability and focuses on the time and place in which the protection is provided, and trace the objective scope of the protection and the solutions related to the possibility to lift the parliamentary immunities. The analysis leads to the conclusion that non-accountability is similar in different countries, has undergone few modifications over the years, and it is permanently formed. In the case of non-violability, there are more extensive differences, in particular in the objective scope and the degree of protection. However, various solutions prove that there is not a single universally accepted model of immunity and that the scope of the guaranteed protection can be more diverse, it can be subject to change, and be adapted to the changes in political systems and the political and social expectations.
Grading AG Szpunar's Opinion in Case C-18/18 – A Caution against Worldwide Content Blocking as Default
Authors: Svantesson Dan
Published: October 2019

On 4th of June 2019, Advocate General Szpunar delivered his Opinion in Case C-18/18 between Eva Glawischnig-Piesczek (an Austrian politician) and Facebook Ireland Limited. The politician had sought to have certain current and future content – argued to be defamatory – blocked by Facebook with worldwide effect. This is arguably the most important Internet speech-related case currently before the Court of Justice of the European Union (CJEU) and will doubtlessly influence court reasoning far beyond Europe.This Comment analyses AG Szpunar’s interesting, but problematic, Opinion with particular emphasis on his reasoning in relation to the question of scope of jurisdiction; that is, what is the appropriate geographical scope of orders in these circumstances, rendered by a court that has personal jurisdiction and subject matter jurisdiction.
Algorithmic Copyright Enforcement and AI: Issues and Potential Solutions through the Lens of Text and Data Mining
Authors: Tóth Andrea Katalin
Published: October 2019

Although digitalization and the emergence of the Internet has caused a long-term crisis for copyright law, technology itself also seems to offer a seemingly ideal solution to the challenges of digital age: copyright has been a major use case for algorithmic enforcement from the early days of digital rights management technologies to the more advanced content recognition algorithms. These technologies identify and filter possibly infringing content automatically, effectively and often in a preventive fashion. These methods have been criticized for their shortcomings, such as the lack of transparency, bias and the possible impairment of fundamental rights. Self-learning machines and semi-autonomous AI have the potential to offer even more sophisticated and expeditious enforcement by code, however, they could also aggravate the aforementioned issues. As the EU legislator envisions to make the use of such technologies essentially obligatory for certain online content sharing service providers (via the infamous Article 17 of the directive on copyright in the digital single market), the assessment of the situation in light of future technological development has become a current topic.This paper aims to identify the main issues and potential long-term consequences of creating legislation that practically requires the employment of such filtering algorithms as well as their solutions. This paper focuses on the potential role a broad copyright exception for text and data mining could play in counterbalancing the issues associated with algorithmic enforcement.
Problematika experimentálního výzkumu buddhistických meditací
Authors: Kotherová Silvie
Published: October 2019

Meditace jsou od 60. let 20. století stabilní součástí moderního vědeckého výzkumu. V rámci psychologie jsou meditace chápány často terapeuticky, co je spojeno s misijními strategiemi buddhistických skupin směrem na Západ. Tato tendence určila i další psychologický výzkumný program a vedla k „naivní“ psychologizaci a homogenizaci meditací ignorujíc jejich kulturní, historický a náboženský kontext. S tím souvisí i nedostatečné definování pojmu meditace a jeho další uchopování pro potřeby experimentu. Tato studie se snaží představit odlišný přístup k experimentálnímu výzkumu meditací. Ten je založen na důkladnějším vymezení konkrétního typu meditace a jeho prvků a na následném zkoumání jejího efektu na narušení tělesného obrazu sleduje různé intervenující proměnné. Studie se nezaměřuje jen na referování o průběhu a výsledcích experimentu, ale sleduje i mnohá, často nelehká, metodologická rozhodnutí, která je nutno při experimentálním výzkumu (nejen) meditací učinit. Obecně vzato, klíčový je integrovaný interdisciplinární přístup, který spojuje expertízy z různých oblastí.

Politizace pracovníků ministerstev v České republice dle pracovních pozic: současná teorie a praxe
Authors: Kohoutek Jan , Nekola Martin
Published: October 2019

The article analyses perceptions of the nature and extent of politicization by officials at eleven ministries of the Czech Republic. The empirical part of the article is based on a large-N inquiry among ministerial officials that were divided into four groups (directors of section, directors of department, heads of division, rank-and-file officials) following their work position. From the theory perspective, the article builds upon two types of politicization – formal and functional – with the latter further subdivided into hidden and partisan politicization. Such theoretical assumptions help towards formulating six hypotheses verified with relation to the four work positions. The corresponding analysis of officials’ perceptions by position attests to a rather limited extent of the two main types of politicization with the exception of functional politicization of top management (director of section). Compared to the other three positions, directors of section show more proclivity to personal contacts (functional-hidden politicization) or to direct party political nomination (functional-partisan politicization). Unlike the conclusions of previous, largely expert or qualitative, inquiries, the officials’ perceptions generally point towards rather moderate politicization of the Czech ministries without excessive direct influence of political representatives.
Materialita pohybu: vztah mezi nevidomostí a městským prostorem
Authors: Porkertová Hana
Published: October 2019

This article thematizes relations between visual impairment and urban space, drawing from the analytical perspective of actor-network theory (ANT). It traces the ways in which visually impaired people create specific connections with space and how they transform it. Urban space is configured for use by able-bodied persons, for whom movement within it is easy and seems to be disembodied. However, for those who defy the standardization of space, the materiality of movement is constantly present and visible, because the passages are difficult to make and are not ready in advance. These materialities, as well as the strategies that people use to make connections with urban space, differ according to the assemblages that visually impaired people create. A route is different with a cane, a human companion, a guide dog, or the use of a combination of such assistance; the visually impaired person pays attention to different clues, follows specific lines, and other information is important and available. Each configuration makes it possible or impossible to do something; this shows disability as dynamic, and demonstrates the collective nature of action, which is more visible and palpable in the case of a disabled person.
