Published: July 2019

Abstract. Lacustrine sediments are important sites of fixed nitrogen (N) elimination through the reduction of nitrate to N2 by denitrifying bacteria, and are thus critical for the mitigation of anthropogenic loading of fixed N in lakes. In contrast, dissimilatory nitrate reduction to ammonium (DNRA) retains bioavailable N within the system, promoting internal eutrophication. Both processes are thought to occur under oxygen-depleted conditions, but the exact O2 thresholds particularly of DNRA inhibition are uncertain. In O2-manipulation laboratory experiments with dilute sediment slurries and 15NO3− additions at low- to sub-micromolar O2 levels, we investigated how, and to what extent, oxygen controls the balance between DNRA and denitrification in lake sediments. In all O2-amended treatments, oxygen significantly inhibited both denitrification and DNRA compared to anoxic controls, but even at relatively high O2 concentrations (≥ 70 µmol L−1), nitrate reduction by both denitrification and DNRA was observed, suggesting a relatively high O2 tolerance. Nevertheless, differential O2 control and inhibition effects were observed for denitrification versus DNRA in the sediment slurries. Below 1 µmol L−1 O2, denitrification was favored over DNRA, while DNRA was systematically more important than denitrification at higher O2 levels. Our results thus demonstrate that O2 is an important regulator of the partitioning between N-loss and N-recycling in sediments. In natural environments, where O2 concentrations change in near bottom waters on an annual scale (e.g., overturning lakes with seasonal anoxia), a marked seasonality with regards to internal N eutrophication versus efficient benthic fixed N elimination can be expected.

Abstract. Weather diaries constitute an important source of data
for historical climatology, employed in the analysis of weather patterns for
both the pre-instrumental and the early instrumental periods. Among the many
weather diaries that exist in Europe, the daily records kept by the Reverend
Šimon Hausner from Buchlovice in south-east Moravia (Czech Republic),
covering the 1803–1831 period, are particularly useful. His qualitative
daily weather descriptions enable the construction of series for
temperature, precipitation, cloudiness, wind, and other weather phenomena
(particularly thunderstorms and fogs), supplemented by a number of
phenological and agricultural work records. His data related to temperature
and precipitation patterns were quantified into a series of weighted
temperature and precipitation indices on 7-degree scales, which were
subsequently compared with standard meteorological observations from the
secular meteorological station in Brno. This comparison indicates that
Hausner's observations are highly reliable and confirms the importance of
his data for a better understanding of the variability in the regional
climate in the period of early instrumental measurements in Moravia. At the
same time, it reveals the importance of weather-related documentary data in
the overlap period with instrumental meteorological observations.
FORHYCS v1.0: A spatially distributed model combining hydrology
and forest dynamics
Authors: Speich Matthias J. R. , Zappa Massimiliano , Scherstjanoi Marc , Lischke Heike
Published: July 2019

Abstract. We present FORHYCS (FORests and HYdrology under Climate Change in Switzerland), a distributed ecohydrological model to assess the impact of climate change on water resources and forest dynamics. FORHYCS is based on the coupling of the hydrological model PREVAH and the forest landscape model TreeMig. In a coupled simulation, both original models are executed simultaneously and exchange information through shared variables. The simulated canopy structure is summarized by the leaf area index (LAI), which affects local water balance calculations. On the other hand, an annual drought index is obtained from daily simulated potential and actual transpiration. This drought index affects tree growth and mortality, as well as a species-specific tree height limitation. The effective rooting depth is simulated as a function of climate, soil and simulated above-ground vegetation structure. Other interface variables include stomatal resistance and leaf phenology. Case study simulations with the model were performed in the Navizence catchment in the Central Swiss Alps, with a sharp elevational gradient and climatic conditions ranging from dry inneralpine to high alpine. In a first experiment, the model was run for 500 years with different configurations. The results were compared against observations of vegetation properties from national forest inventories, remotely sensed LAI and high-resolution canopy height maps from stereo aerial images. Two new metrics are proposed for a quantitative comparison of observed and simulated canopy structure. In a second experiment, the model was run for 130 years under idealized climate change scenarios: daily temperature was increased by up to 6 K, and precipitation altered by 10 %, with a gradual change over 35 years. The first experiment showed that model configuration greatly influences simulated vegetation structure. In particular, simulations where height limitation was dependent on environmental stress showed a much better fit to canopy height observations. Spatial patterns of simulated LAI were more realistic than for uncoupled simulations of the forest landscape model, although some model deficiencies are still evident. Under idealized climate change scenarios, the effect of the coupling varied regionally, with the greatest effects on simulated streamflow (up to 40 mm y−1 difference with respect to a simulation with static vegetation parameters) seen at the valley bottom and in regions currently above the treeline. This case study shows the importance of coupling hydrology and vegetation dynamics to simulate the impact of climate change on ecosystems. Nevertheless, it also highlights some challenges of ecohydrological modelling, such as the need to realistically simulate plant response to increased CO2 concentrations, and process uncertainty regarding future land cover changes.
BP Neural Network and improved Particle Swarm Optimization for Transient Electromagnetic Inversion
Authors: Zhang Huaiqing , Li Ruiyou , Yu Nian , Li Ruiheng , Zhuang Qiong
Published: July 2019

Abstract. As one of the most active nonlinear inversion methods in transient electromagnetic (TEM) inversion, the back propagation (BP) neural network has high efficiency because the complicated forward model calculation is unnecessary in iteration. The global optimization ability of the particle swarm optimization (PSO) is adopted for amending BP's sensitivity on initial parameters, which avoids it falling into local optimum. A chaotic oscillation inertia weight PSO (COPSO) is proposed in accelerating convergence. The COPSO-BP algorithm performance is validated by two typical testing functions and then by two geoelectric models inversion. The results show that the COPSO-BP method has better accuracy, stability and relative less training times. The proposed algorithm has a higher fitting degree for the data inversion, and it is feasible in geophysical inverse applications.
The Complexity of Relationship between Corporate Social Responsibility (CSR) and Financial Performance
Authors: P Golrida Karyawati , Subroto Bambang , T Sutrisno , Saraswati Erwin
Published: July 2019

This study argues that, inconsistent results of the Corporate Social Responsibility (CSR) relationship with financial performance is due to the complexity of relationship between two variables. The complexity of relationship stems from the nature of CSR, which is unseparable from its environment. This nature of relationship brings unfavourable impact on empirical research. The conclusion obtained from empirical evidents of such relationship will be highly contextual and lack generalization. This study proposes variables that led to the complexity of CSR relationship and financial performance, which are country characteristics as well as CSR forms and dimensions. Country characteristics determine the tendency of CSR practices, which finally influence the strength of CSR relationship with financial performance. The selection of CSR forms and dimensions to be done is part of a company’s strategy in an effort to achieve legitimacy.

El cosmonauta Ivan Istochnikov en la era de la postfotografía
Authors: Benito Mario F.
Published: July 2019

La fotografía está sufriendo una transformación radical debido a tres factores del desarrollo tecnológico: la digitalización, el nacimiento y el acelerado desarrollo de Internet y, por último, la revolución de los dispositivos móviles. Este proceso en curso está dando como resultado lo que se ha venido en llamar postfotografía. Conceptos clave en la fotografía se están “desmaterializando” en el medio “líquido” digital de la Red de redes, donde la autoría individual de las imágenes está dejando paso a formas visuales de expresión en las que se crea nuevo sentido, y conceptos como verdad y memoria entran en crisis. Este trabajo cuestiona si en la actual era postfotográfica tendría sentido el proyecto Sputnik, realizado por Joan Fontcuberta en 1997 con el propósito de reflexionar sobre los usos de la fotografía en aquel momento. Tras detallar la aventura del cosmonauta Ivan Istochnikov y lo que sucedió en los medios de comunicación, se estudia las características de la postfotografía, para concluir que una obra así no tendría sentido después de la mencionada transformación del hecho fotográfico.
Etnografía y "Creación Colectiva Teatral". Una década de "artivismo" con personas sin hogar en Sevilla
Authors: Del Campo-Tejedor Alberto , Cordero-Ramos Nuria , Muñoz-Bellerin Manuel
Published: July 2019

Las deficiencias de las políticas públicas con el sinhogarismo obligan a la búsqueda de alternativas que conviertan a las personas sin hogar (PSH) en actores y no solo en sujetos pasivos, asistencializados y burocratizados. Este artículo describe las lógicas, logros y retos de un proyecto de investigación y artivismo desarrollado durante una década con PSH en Sevilla, con el objetivo de comprender y contribuir a revertir su situación de exclusión, y muy particularmente la institucionalización de las PSH en centros de acogida. Enmarcado como investigación-acción-participativa, el proyecto se ha articulado con dos métodos; por un lado, la Creación Colectiva Teatral (CCT), y por otro, la Etnografía, entendida como práctica de con-vivencia, diálogo y experimentación. La propuesta ha permitido la problematización, comunicación y deconstrucción de ciertos obstáculos experimentados por las PSH, y ha generado ámbitos de creatividad, educación e investigación-acción, tanto en la gestación, representación y recepción de las obras teatrales, como en su difusión en Internet y las redes sociales. Ello ha alentado el empoderamiento y la capacitación de las PSH, notablemente identificadas con un proceso de creación basado en el aprendizaje mutuo de los presupuestos ontológicos, epistemológicos, axiológicos y emocionales del científico y las PSH.

Authors: Ramon Ricard
Published: July 2019

El artículo es producto de un proceso de investigación basado en la metodología de la Photo Based Research realizada con alumnado universitario en formación como futuros docentes. Parte del análisis de prácticas artísticas performativas del cuerpo, en relación con un entorno de mediación pedagógica y los objetos que lo configuran, para establecer una nueva mirada analítica sobre el papel de mediación del entorno y sus objetos sobre la posición del docente y su identidad. Ello nos permite vislumbrar y poder subvertir, utilizando la propuesta de análisis de visualización de entornos mediáticos, que desarrollamos en el artículo, estos efectos de mediación. Con ello, podemos articular, por medio de la visualización, propuestas de proyección alternativas y de transformación y cambio de nuestra posición en el medio y de transformación del medio. A partir del análisis del proceso investigador, se hacen visibles los posicionamientos del alumnado en su proyección docente en el medio. Concluimos nuestra investigación constatando que, la propuesta de visualización de entornos mediáticos entre cuerpos y objetos resulta efectiva como elemento de reflexión, de aprendizaje y construcción de conocimientos nuevos sobre el mismo y sobre nosotros, posibilita la creación de nuevos mundos posibles y desafía la inmutabilidad del poder mediático del entorno.
Videojuegos y literatura: Estudio de tres casos de intertextos hispanoamericanos
Authors: Núñez-Pacheco Rosa , Castillo-Torres Daniel , Navarrete-Cardero Luis
Published: July 2019

Esta investigación establece relaciones entre distintas producciones videolúdicas y obras literarias representativas del ámbito hispanoamericano. El vínculo entre el mundo de los videojuegos y la literatura es un tema aún poco explorado, pero adquiere relevancia en el actual dominio de las narrativas transmedia de la cultura contemporánea. Se analiza desde una perspectiva ludoficcional, narratológica y sociocultural un conjunto de remediaciones videolúdicas sobre la novela El ingenioso hidalgo Don Quijote de la Mancha (1615) de Miguel de Cervantes Saavedra; el videojuego Intimate, infinite (Robert Yang, 2014) basado en el cuento “El jardín de senderos que se bifurcan” (1941) de Jorge Luis Borges; y el videojuego Space invaders (Taito, 1978) que inspiró la novela homónima de la escritora chilena Nona Fernández (2013). Se sostiene que la significación de estos artefactos culturales adquiere mayor sentido cuando se establecen los vínculos con otros intertextos y cuando se los examina desde la configuración de los mundos ludoficcionales.
Identidades robadas. Arte, apropiación y extimidad en la vida online
Authors: Baigorri-Ballarín Laura
Published: July 2019

Las redes sociales no sólo han transformado radicalmente las experiencias de privacidad e intimidad, sino que también han propiciado nuevos espacios de análisis sobre las estrategias de socialización, convirtiéndose en un territorio de experimentación prioritario para los artistas que trabajan en propuestas creativas en torno a la identidad y a la preservación de la privacidad y la intimidad. Sus planteamientos extremos dejan al descubierto una persistente necesidad de reafirmación de la autoestima que es paradójicamente opuesta al ejercicio de un control efectivo sobre nuestra visibilidad y sobre la utilización de nuestras imágenes en las redes sociales. El objetivo de esta investigación es examinar críticamente, a través obras de los artistas, la gestión que los usuarios de medios sociales hacen de su identidad compartida; asimismo, averiguar cuáles son sus reacciones cuando sufren robos de imágenes íntimas, o cuando las descubren expuestas en galerías privadas y exhibiciones online. A la violación de la privacidad que ejecutan tanto los individuos como las grandes compañías cuando utilizan información privada de sus usuarios se confrontan las decisiones personales y libres de éstos cuando desean compartir su privacidad y su intimidad; robos y donaciones coexisten en el mismo territorio de la vida conectada.
Visualidad y consumo en Chile. Un análisis de la publicidad del "mall" en los años ochenta
Authors: Vergara-Leyton Enrique , Garrido Claudio , De Simone Liliana , Condeza Rayén , Pino Bárbara
Published: July 2019

A través de este artículo se presentan los resultados de una investigación cuyo objetivo fue explorar la relación entre visualidad y consumo en Chile, tomando como referencia el caso de mall Parque Arauco en los años ochenta. Se postula que el protagonismo sociocultural que adquiere Parque Arauco en la sociedad chilena sería consecuencia de un particular relato visual que, junto con otorgar un valor estético a la experiencia de comprar, vincula el consumo con experiencias cotidianas asociadas a nuevos estilos de vida, anhelos y expectativas propias de un proceso de modernización impuesto en un contexto autoritario. A partir de un trabajo de campo que consideró la publicación de avisos publicitarios entre los años 1982 y 1990, se seleccionó un corpus de 6 piezas que fueron analizadas desde una perspectiva cualitativa. Entre los principales hallazgos de este análisis se destaca una dimensión simbólica del consumo más allá de lo funcional asociadas a una nueva forma de entender los espacios de interacción social y de representar la vida cotidiana. En este sentido, el discurso de Parque Arauco anticipa el profundo cambio cultural que experimentará la sociedad chilena en la década de los noventa, al trasladar las expectativas de cambio desde el ámbito político al consumo, en cuanto eje articulador de identidades y de reconocimiento social.

Published: July 2019

El pensamiento crítico no solo es una de las competencias definitorias del perfil profesional del futuro profesorado, sino también una necesidad ineludible para cualquier acción educativa. En este sentido, las capacidades y actitudes críticas representan un papel fundamental en el proyecto de analizar y dominar la gran cantidad de información que caracteriza al contexto social actual. El presente artículo expone una técnica de enseñanza-aprendizaje que posibilita la formación del pensamiento crítico de una forma experiencial y motivacional: el juego de rol. Con el fin de evaluar su impacto, se recogen, mediante cuestionario, las opiniones de 331 estudiantes de primer curso de los Grados de Educación Infantil y Educación Primaria de la Facultad de Educación y Deporte de la Universidad del País Vasco (UPV/EHU). Según dichas opiniones, el alumnado participante considera que la actividad simulada de los debates académicos supone una técnica motivadora para el desarrollo de su pensamiento crítico; a su vez, manifiesta que el juego de rol propuesto constituye una estrategia perfectamente válida para el desarrollo de sus competencias comunicativas y pedagógicas, redundando también en la adquisición de las competencias disciplinares y transversales de los grados.

Authors: Ávalos Ramos Mª Alejandra , Martínez Ruiz Mª Ángeles , Urrea Solano Mª Encarnación
Published: July 2019

Esta investigación analiza la percepción de tres cohortes de estudiantes universitarios de segundo curso, en relación a la desigualdad de género en las aulas de una universidad española y de otra universidad chilena. Dos de estos grupos (94 estudiantes) pertenecen a contextos curriculares masculinizados, como son los estudios de Ciencias de la Actividad Física y Deportiva. El otro grupo formado por 47 estudiantes del Grado de Educación Primara actúa de referente comparativo. La metodología de la investigación tiene un enfoque cualitativo y el análisis de los datos obtenidos se realizó con el programa informático AQUAD 6. Los resultados del estudio muestran que, a pesar de la realidad estadística que refleja la escasa presencia de las mujeres en el deporte, el alumnado universitario no es demasiado consciente de las sutiles formas de exclusión que experimentan las mujeres en el aula y de la forma en que esto puede influir en su carrera profesional.

This study aims to investigate the impacts of earning management on the stock returns of listed industrial firms on the Amman Stock Exchange, with the observance of (firm size and operating cash flow) as control variables for the study. In order to fulfill the purposes of this study, the researcher utilized (Jones model) and (Modified Jones model) to measure earning management through reliance on discretionary accruals as evidence of earnings management practices, and utilize (Market Return On the Stock model) to measure stock returns, and the study population was Mining and Extraction Industries firms also Food and Beverages firms listed in Amman Stock Exchange, the study was conducted on a sample of 18 firms which represents 75% of the study population for the period from 2014 to 2018, In addition to using descriptive and analytical approach to data collection, analysis, and testing hypotheses through financial statements of the firms in the study, the researcher has used the Statistical Package for Social Sciences (SPSS) program to test the hypotheses. This study creates many results some of which are: there is an insignificant relationship between earnings management practices and stock returns for listed industrial firms in Amman Stock Exchange during the study period at the significance level of 5%, Which reflects the poor efficiency in Amman Stock Exchange and not the information contained in the financial statements issued and therefore not impact stock prices, which in turn affects the stock returns, and there is an insignificant relationship between stock returns and operating cash flow at the level of significance of 5%, In addition found significant correlation between firm size and stock returns at the significance level of 1%. The researcher presented a set of recommendations; the following are most valuable: the importance of increasing the awareness of the relevant parties about the unreliability of financial statements issued by industrial companies listed on the Amman Stock Exchange in existence of the earnings management practice and not reflecting the information contained in the financial statements on prices and stock returns by holding seminars, conferences and meetings also Activating the role of audit committees further to be able to detect the practice of earnings management and decrease it.
Controlling Mechanisms for Molybdenum Isotope Fractionation in Porphyry Deposits: The Qulong Example
Authors: Li Yang , McCoy-West Alex J. , Zhang Shuang , Selby David , Burton Kevin W. , Horan Kate
Published: July 2019

Molybdenite-bearing porphyry deposits are the predominant supplier of molybdenum to industrialized society and one of the main hosts of Mo in the upper continental crust. The Mo isotope compositions (δ98/95Mo, normalized to NIST3134 equals 0‰) of molybdenite show considerable variation (–1.62 to +2.27‰), but the factors controlling this variability remain poorly constrained. This information is critical for underpinning genetic models of porphyry deposits, understanding elemental cycling, and utilizing the δ98/95Mo of marine sediments as a paleoredox proxy. Using the well-characterized Qulong porphyry Cu-Mo deposit (Tibet) as an example, here we discuss how rapid cooling, facilitated by mixing hot magmatic fluid with cold meteoric water, can be a controlling factor on efficient mineralization, and then tackle how fluid evolution regulates molybdenum isotope fractionation. Molybdenites, which preferentially partition isotopically light Mo (Rayleigh fractionation), precipitated from a single fluid will develop a heavier δ98/95Mo composition over time, and this also creates heterogeneous δ98/95Mo between molybdenite grains. Whereas a fluid undergoing multiple episodes of intensive boiling will gradually lose its isotopically heavy Mo to the vapor phase, molybdenites crystallizing successively from the residual liquid will then have lighter δ98/95Mo over time. However, when mineralization efficiency becomes too low, a negligible variation in δ98/95Mo of molybdenite is observed. Given that the mineralization efficiency (i.e., the amount of Mo crystallized as molybdenite from the fluid) rarely reaches 100% and molybdenite favors isotopically light Mo, the presence of a residual fluid with isotopically heavy Mo is inevitable. This residual fluid may then become trapped in alteration halos; hence, δ98/95Mo has the potential to aid in locating the mineralization center (e.g., lighter δ98/95Mo toward the orebody). The residual fluid may also feed surface hydrological systems and eventually impact Mo cycling. Our study highlights that understanding the controls of isotope fractionation is critical to bridge the gap between ore formation and elemental cycling, and that other transition metals (e.g., Cu, Fe, and Zn) may follow similar trajectories.
Effect of artificial seawater and feeding frequency on the larval culture of freshwater Amazonian ornamental fish banded cichlid Heros severus (Heckel, 1840) and angelfish Pterophyllum scalare (Schultze, 1823)

Published: July 2019

The present study aimed to evaluate the effect of salinity and feeding frequency on zootechnical performance of Pterophyllum scalare and Heros severus five-day-old post-larvae. Two experiments were performed in a completely randomized experimental design in a 5 × 2 factorial scheme, with 5 different NaCl concentrations (0, 2, 4, 6 and 8 g/L) and 2 feeding frequencies (2 and 4 times a day). P. scalare showed the highest survival rates (p<0.05) when subjected to salinities of 0, 2 and 4 g/L (97.50–96.25%), and higher values (p<0.05) for standard length (13.22 mm), weight (64.64 mg) and specific growth rate (15.41% per day) when fed 4 times a day. For this species, feeding frequency did not influence survival rates. H. severus, in turn, showed higher survival rates in water without the addition of salt (96.25%) and the highest standard length in salinity of 2 g/L (11.80 mm). H. severus fed 4 times a day and presented the highest values (p<0.05) for most of the growth variables (weight: 57.28 mg, specific growth rate: 18.30% per day). The results of the present study suggest that banded cichlid post-larvae showed higher survival rates in water without salt addition, however, the best growth of this species occurred at the salinity of 2 g/L. In contrast, angelfish post-larvae can be cultivated in salinities of up to 4 g/LNaCl. A feeding frequency of 4 times per day is recommended for both species.

Published: July 2019

Credit risk can be effectively managed by evaluating and predicting the credit worthiness of a customer or a corporate. Credit scores are calculated to assess the credit worthiness. It helps the financial institutes to know the amount and dimensions of risk involved in different credit transactions. Credit scoring helps the financial institutes to decide whether or not to lend. It also helps in deciding the price of a particular exposure, the appropriate credit facility and different risk tools.  This research paper focuses on identifying the triggers of credit default. It also focuses on checking and predicting the financial solvency of the borrowers of non-banking financial companies and assigning the credit worthiness to these companies. The data is collected from a Mumbai based NBFC. The data for the study are extracted from balance sheet and profit &loss statement of these companies. The data includes the financial ratio variables for forty companies. Altman's Z-score is used to find credit worthiness and DuPont technique is used to find the main causes of financial distress. The results of this research highlights that the borrowing companies having a lower return on equity (ROE) are prone to be in distress zone. This research would help the financial institutions to identify the most likely defaulter companies and to segment the clients/companies in safe, grey and distressed zones. The results are robust to sub-samples.

The objective of the study is the assessment of the microbial ecology and safety of fish in Greece using next-generation sequencing (NGS) and the correlation of the species of microbial flora with the production of histamine. Fourteen different fish species were obtained from local fish stores (Greece) within 1 day from capture. The initial microbiota in fish flesh was determined using NGS. The main pathogenic bacterial species identified in the tested fish samples included Vibrio spp., Clostridium spp., Staphylococcus, Flavobacterium and Janthinobacterium representing both native freshwater habitats and contaminants arising from different sources, including sewage and direct contamination by wild animals, livestock, and feed. The initial spoilage microbiota of fish consisted of several psychrotrophic Gram-negative bacteria, such as Pseudomonas, Acinetobacter, Moraxella, Shewanella, Psychrobacter, Lactobacillus, Brochothrix and Photobacterium. The results of the study show the potential of the application and the usefulness of NGS for the determination of microbial flora associated with food-borne diseases and spoilage in fish products. Histamine formation correlated with the valid reads (concentration and number of bacteria) and slightly with the genus of the identified microorganisms.

Published: July 2019

Land use shows the interaction between human and nature, and its impacts especially on runoff have received global attention and required more research studies. However, watershed database is generally available only for very large scales and not yet adapted to small scales. This paper presents a methodology for watershed delineation and potential influence assessment of runoff on the small watersheds in Japan based on the locations of the official observatory point data. Flow direction, flow accumulation, snap pour point and watershed recognition were analyzed by using the D8 algorithm and 10 m × 10 m DEM data of Japan. Totally 3831 watersheds were delineated by defining snapping pour point distance of 50 m as the input value, and the nation-wide watershed database was established. According to the suggestion of Notification No. 521 from the Ministry of Land, Infrastructure and Transport of Japan and land use/land cover data from JAXA satellite Alos-2, comprehensive runoff coefficient (CRC) was calculated by the weighted average method and divided into 10 levels by the equal interval method using ArcGIS. The obtained watershed boundary lines were almost identical to the ridge lines in the mountain area which accounts for more than half of Japan. The CRC values in the biggest cities such as Tokyo and Osaka were the highest, indicating these cities would receive the highest impacts of runoff. These results can provide the technical support for the decision-making on watershed management. The creation of small-scale watershed database would provide basic materials for the subsequent research such as flood prevention, water shortage and biogeochemical cycle of the sustainable regional development.
A Model for Prioritization of Improvement Opportunities Based on Quality Costs in the Process Interdependency Context
Authors: Glogovac Maja , Filipovic Jovan
Published: July 2019

In this paper, the PAF (preventive-appraisal-failure) quality costs model is used on the process level, in order to identify those processes which are critical as a top-priority for improvement. The elements of quality costs are considered in relation to the outputs of the processes, where the principle that one process affects the quality of another process by its outputs is taken into account. That is why the failure costs of the affected processes should also be assigned to the quality costs of the observed process. Using the factors proposed in the Process cost model, costs are identified and calculated for each process for two moments: the current (before improvements) and desired (after improvements). Improvements are implemented on the basis of the causes of nonconformity analysis and according to the PAF model assumption that preventive and appraisal activities reduce failure costs and the total costs of quality. The difference between the total costs of quality in two observed moments is seen as the greatest possible quality cost reduction for the observed process. This value is used as a criterion for ranking the processes according to their priority for improvements, taking into account the assumption of the PAF model that greater costs mean lower quality and hence a higher priority for improvement.
The Role of Information Sources in Firm R&D Activities – The Case of German Knowledge Intensive Industries
Authors: Prokop Viktor , Stejskal Jan , Hájek Petr
Published: July 2019

R&D activities affect the ability to create innovation for every firm. Many studies have shown that R&D activities are influenced by a number of determinants and the environment (R&D milieu) in which individual economic entities exist. Due to the nature of firms´ production, it is important to note that not every firm needs the same amount of information and knowledge. This thesis will also affect the efficiency of the use of information sources in R&D activities. In practice, it is necessary to know the dependence of companies and their R&D activities on the available information sources so that public policy makers can better target public policy and possible financial support schemes (grant schemes), because, the one size-fits all principle cannot be assumed. Therefore, the aim of this paper is to analyze the role of information resources in the knowledge intensive industries in the strongest EU economy, i.e. Germany. For the analysis, Eurostat CIS data and own regression model were used. The results show that the knowledge environment has a major impact on the development of R&D in the German knowledge intensive firms. German companies sourced information from the market (especially clients and customers), and all firms acquired information and knowledge from collaborating with universities. The biggest impetus for the realization of R&D activities is for firms to focus on markets outside the EU.
Rorty on Hermeneutical Injustice, Liberal Redescription and Utopian Imagination
Authors: Penelas Federico
Published: July 2019

My purpose is to use Miranda Frickers’ concepts of testimonial injustice and hermeneutical injustice to draw a distinction between the policy of tolerance and the policy of solidarity in Rortyan liberalism.  I shall focus on the policy of solidarity interpreted as unfolding in two phases of the imagination: the phase of critical imagination and that of utopian imagination. I advocate that critical imagination may be understood as focusing on overcoming hermeneutical injustice through what I term liberal redescription.  Lastly, I critique the Rortyan project on what I view as an inadequate inclination to restrict critical imagination on the basis of adopting a criterion that focuses on flaws in the development of utopian imagination.
La noción de logismoí en Evagrio Póntico: el correlato cognitivo de las pasiones enfermas
Authors: Vazquez Santiago Hernán
Published: July 2019

El presente trabajo se propone profundizar en una noción característica de la obra del filósofo tardoantiguo, Evagrio Póntico. Dicha noción es la de logismoí. Las distintas modulaciones y sentidos con que Evagrio se refiere a este tópico, justifica la necesidad de acercarse a éste a fin de lograr una conceptualización coherente del mismo que contemple todos sus sentidos. Se trata principalmente de dilucidar si estamos frente a una realidad psíquica y/o frente a lo que nuestro autor considera una sugestión preternatural. Creemos que comprender estos  como el correlato cognitivo de las pasiones, enfermas a raíz de la ignorancia de sí, constituye la clave de bóveda para acceder a una conceptualización coherente.
Nomadismo y espíritu libre. La noción de Freisinnigkeit en el pensamiento político nietzscheano
Authors: Quejido Alonso Oscar
Published: July 2019

En diferentes ocasiones a lo largo de su obra, F. Nietzsche utiliza el término Freisinnigkeit para referirse a una cierta «liberalidad de espíritu». Esta noción se relaciona directamente con la de espíritu libre, así como con el planteamiento nietzscheano del nomadismo y, más particularmente, con el de la diáspora judía. En este artículo mostraremos cómo, por medio de estas nociones, Nietzsche genera un espacio para la reflexión política en el que es posible integrar cuestiones tales como su radical crítica al nacionalismo.
Dimensiones ético-políticas del concepto "pathos de la distancia" en la filosofía de Nietzsche
Authors: García-Granero Marina
Published: July 2019

En el presente artículo me propongo elucidar el significado del concepto “pathos de la distancia” y sus implicaciones ético-políticas, destacando su sentido y coherencia con el conjunto del pensamiento nietzscheano. La tesis fundamental es que el pathos de la distancia, como característica básica del ideal noble, muestra cómo el concepto de supremacía política en Nietzsche se disuelve siempre en una idea de preeminencia anímica. La reflexión se enmarca dentro de la crítica nietzscheana de la cultura, la política y la educación, y su propuesta de reforma de los valores dominantes de la sociedad, entre ellos, los que configuran la subjetividad y la individualidad. Se estudian las diversas dimensiones del pathos de la distancia: como articulación jerárquica, como principio de individualidad, como parte la Gran Política y como elemento del pensamiento de la cría (Züchtung) de la humanidad.Palabras clave: pathos de la distancia, valor, moral, gran política, cría.
How many ways to say goodbye? The latent class structure and psychological correlates of European Union sentiment in a large sample of UK adults
Authors: Lewis Gary J. , de-Wit Lee
Published: July 2019

Most psychological research on Brexit categorises participants as either leave or remain supporters. In the current study we take a data-driven approach and identify different clusterings of attitudes towards the European Union (EU) using latent class analysis (LCA), as well as how these classes differ across a range of important social and psychological variables. This analysis revealed 10 distinct classes of voters in a large (N = 15860) adult sample of UK citizens using data from the British Election Study. These classes ranged from being quite uniformly pro- or anti-EU in sentiment, to more mixed groups with more complex patterns of attitudes. The classes that included majority-remain supporters were younger and better educated, and self-rated more highly on the measures of actively open-minded thinking, openness, political trust, and external locus of control. The classes that included majority-leave supporters were older and less well educated, and self-rated more highly on the measures of authoritarianism and conscientiousness. However, there were also notable demographic and psychological differences within the classes associated with leavers and remainers. A full consideration of these attitudinal nuances will be necessary to achieve a deeper understanding of why the UK decided to leave the EU.
