Published: December 2020

The patient population needing physical rehabilitation in the upper extremity is constantly increasing. Robotic devices have the potential to address this problem, however most of the rehabilitation robots are technically advanced and mainly designed for clinical use. This paper presents the development of an affordable device for upper-limb neurorehabilitation designed for home use. The device is based on a 2-DOF five-bar parallel kinematic mechanism. The prototype has been designed so that it can be bound on one side of a table with a clamp. A kinematic optimization was performed on the length of the links of the manipulator in order to provide the optimum kinematic behaviour within the desired workspace. The mechanical structure was developed, and a 3D-printed prototype was assembled. The prototype embeds two single-point load cells to measure the force exchanged with the patient. Rehabilitation-specific control algorithms are described and tested. Finally, an experimental procedure is performed in order to validate the accuracy of the position measurements. The assessment confirms an acceptable level of performance with respect to the requirements of the application under analysis.

In this paper, a comparison of the impact of major sudden stratospheric warmings (SSWs) in the Arctic in February 2018 (SSW1) and January 2019 (SSW2) on the mid-latitude mesosphere is given. The mesospheric carbon monoxide (CO) and zonal wind in these two major SSW events were observed at altitudes of 70–85 km using a microwave radiometer (MWR) at Kharkiv, Ukraine (50.0°N, 36.3°E). Data from ERA-Interim and MERRA-2 reanalyses and Aura Microwave Limb Sounder measurements were also used. It is shown that: (i) The differences between SSW1 and SSW2, in terms of local variability in zonal wind, temperature, and CO in the stratosphere and mesosphere, were clearly defined by the polar vortex (westerly in cyclonic circulation) and mid-latitude anticyclone (easterly) migrating over the MWR station, therefore; (ii) mesospheric intrusions of CO-rich air into the stratosphere over the Kharkiv region occurred only occasionally, (iii) the larger zonal wave 1–3 amplitudes before SSW1 were followed by weaker polar vortex recovery than that after SSW2, (iv) the strong vortex recovery after SSW2 was supported by earlier event timing (midwinter) favoring vortex cooling due to low solar irradiance and enhanced zonal circulation, and (v) vortex strengthening after SSW2 was accompanied by wave 1–3 amplification in March 2019, which was absent after SSW1. Finally, the influence of the large-scale circulation structures formed in individual major SSW events on the locally recorded characteristics of the atmosphere is discussed.

Published: December 2020

In this study, 16 satellite-based precipitation products (SPPs) comprising satellite, gauge and reanalysis datasets were assessed on a monthly time step using precipitation data from 11 gauge stations across Nigeria within the 2000–2012 period as reference. Despite the ability of some of the SPPs to reproduce the salient north–south pattern of the annual rainfall field, the Kling–Gupta efficiency (KGE) results revealed substantial discrepancies among the SPP estimates. Generally, the SPP reliability varies spatially and temporally, with all SPPs performing better over part of central Nigeria during the dry season. When we compared the real-time and adjusted satellite-based products, the results showed that the adjusted products had a better KGE score. The assessment also showed that the reliability of integrated multi-satellite retrievals for Global Precipitation Mission (IMERG) products was consistent with that of their predecessor Tropical Rainfall Measuring Mission (TRMM) multi-satellite precipitation analysis (TMPA). Finally, the best overall scores were obtained from multi-source weighted-ensemble precipitation (MSWEP) v.2.2 and IMERG-F v.6. Both products are therefore suggested for further hydrological studies.

Published: December 2020

Radars are used to retrieve physical parameters related to clouds and fog. With these measurements, models can be developed for several application fields such as climate, agriculture, aviation, energy, and astronomy. In Chile, coastal fog and low marine stratus intersect the coastal topography, forming a thick fog essential to sustain coastal ecosystems. This phenomenon motivates the development of cloud radars to boost scientific research. In this article, we present the design of a Ka-band cloud radar and the experiments that prove its operation. The radar uses a frequency-modulated continuous-wave with a carrier frequency of 38 GHz. By using a drone and a commercial Lidar, we were able to verify that the radar can measure reflectivities in the order of −60 dBZ at 500 m of distance, with a range resolution of 20 m. The lower needed range coverage imposed by our case of study enabled a significant reduction of the instrument cost compared to existent alternatives. The portability and low-cost of the designed instrument enable its implementation in a distributed manner along the coastal mountain range, as well as its use in medium-size aerial vehicles or balloons to study higher layers. The main features, limitations, and possible improvements to the current instrument are discussed.

The theoretical temporal resolution limit tT of a silicon photodiode (Si PD) is 11.1 ps. We call “super temporal resolution” the temporal resolution that is shorter than that limit. To achieve this resolution, Germanium is selected as a candidate material for the photodiode (Ge PD) for visible light since the absorption coefficient of Ge for the wavelength is several tens of times higher than that of Si, allowing a very thin PD. On the other hand, the saturation drift velocity of electrons in Ge is about 2/3 of that in Si. The ratio suggests an ultra-short propagation time of electrons in the Ge PD. However, the diffusion coefficient of electrons in Ge is four times higher than that of Si. Therefore, Monte Carlo simulations were applied to analyze the temporal resolution of the Ge PD. The estimated theoretical temporal resolution limit is 0.26 ps, while the practical limit is 1.41 ps. To achieve a super temporal resolution better than 11.1 ps, the driver circuit must operate at least 100 GHz. It is thus proposed to develop, at first, a short-wavelength infrared (SWIR) ultra-high-speed image sensor with a thicker and wider Ge PD, and then gradually decrease the size along with the progress of the driver circuits.

Published: December 2020

Biosensors are small but smart devices responding to the external stimulus, widely used in many fields including clinical diagnosis, healthcare and environment monitoring, etc. Moreover, there is still a pressing need to fabricate sensitive, stable, reliable sensors at present. DNA origami technology is able to not only construct arbitrary shapes in two/three dimension but also control the arrangement of molecules with different functionalities precisely. The functionalization of DNA origami nanostructure endows the sensing system potential of filling in weak spots in traditional DNA-based biosensor. Herein, we mainly review the construction and sensing mechanisms of sensing platforms based on DNA origami nanostructure according to different signal output strategies. It will offer guidance for the application of DNA origami structures functionalized by other materials. We also point out some promising directions for improving performance of biosensors.
Crosstalk-Reduced Double-Layer Half-Divided Volume Holographic Concentrator for Solar Energy Concentration
Authors: Kao Hongxu , Ma Jianshe , Wang Chengchen , Wu Taihui , Su Ping
Published: December 2020

A new double-layer sunlight concentration system, where each layer is divided into two regions, is proposed, and the system has four volume holograms. Since the four holograms convert light in different directions, the interlayer crosstalk is reduced, and the system has a high concentration ratio. The simulation results show that the concentration system can achieve a 30° operation angle range. The holograms are fabricated on photopolymer substrates, and the left half of the system is implemented using two holograms. The characteristics of the left half of the system are assessed. The agreement of the simulation and experimental results on diffraction efficiency validates the proposed method. The tested monochromatic concentration ratio can achieve a record of 418.8, and the concentration ratio under sunlight is 5.38. The experiment results of light use efficiency are close to the simulation with non-crosstalk, which indicates that the interlayer crosstalk is small.

Published: December 2020

Accurate and quantitative assessment of the impact of natural environmental changes and human activities on total suspended solids (TSS) concentration is one of the important components of water environment protection. Due to the limits of traditional cross-sectional point monitoring, a novel water quality evaluation method based on the Markov model and remote sensing retrieval is proposed to realize the innovation of large-scale spatial monitoring across administrative boundaries. Additionally, to explore the spatiotemporal characteristics and driving factors of TSS, a new three-band remote sensing model of TSS was built by regression analysis for the inland reservoir using the synchronous field spectral data, water quality samples and remote sensing data in the trans-provincial Hedi Reservoir in the Guangdong and Guangxi Provinces of South China. The results show that: (1) The three-band model based on the OLI sensor explained about 82% of the TSS concentration variation (R2=0.81, N=34,  p value<0.01) with an acceptable validation accuracy (RMSE=6.24 mg/L,MRE=18.02%, N=15), which is basically the first model of its kind available in South China. (2) The TSS concentration has spatial distribution characteristics of high upstream and low downstream, where the average TSS at 31.54 mg/L in the upstream are 2.5 times those of the downstream (12.55 mg/L). (3) Different seasons and rainfall are important factors affecting the TSS in the upstream cross-border area, the TSS in the dry season are higher with average TSS of 33.66 mg/L and TSS are negatively correlated with rainfall from upstream mankind activity. Generally, TSS are higher in rainy seasons than those in dry seasons. However, the result shows that TSS are negatively correlated with rainfall, which means human activities have higher impacts on water quality than climate change. (4) The Markov dynamic evaluation results show that the water quality improvement in the upstream Shijiao Town is the most obvious, especially in 2018, the improvement in the water quality level crossed three levels and the TSS were the lowest. This study provided a technical method for remote sensing dynamic monitoring of water quality in a large reservoir, which is of great significance for remediation of the water environment and the effective evaluation of the river and lake chief system in China.

Published: December 2020

A non-destructive measuring technique was applied to test major vine geometric traits on measurements collected by a contactless sensor. Three-dimensional optical sensors have evolved over the past decade, and these advancements may be useful in improving phenomics technologies for other crops, such as woody perennials. Red, green and blue-depth (RGB-D) cameras, namely Microsoft Kinect, have a significant influence on recent computer vision and robotics research. In this experiment an adaptable mobile platform was used for the acquisition of depth images for the non-destructive assessment of branch volume (pruning weight) and related to grape yield in vineyard crops. Vineyard yield prediction provides useful insights about the anticipated yield to the winegrower, guiding strategic decisions to accomplish optimal quantity and efficiency, and supporting the winegrower with decision-making. A Kinect v2 system on-board to an on-ground electric vehicle was capable of producing precise 3D point clouds of vine rows under six different management cropping systems. The generated models demonstrated strong consistency between 3D images and vine structures from the actual physical parameters when average values were calculated. Correlations of Kinect branch volume with pruning weight (dry biomass) resulted in high coefficients of determination (R2 = 0.80). In the study of vineyard yield correlations, the measured volume was found to have a good power law relationship (R2 = 0.87). However due to low capability of most depth cameras to properly build 3-D shapes of small details the results for each treatment when calculated separately were not consistent. Nonetheless, Kinect v2 has a tremendous potential as a 3D sensor in agricultural applications for proximal sensing operations, benefiting from its high frame rate, low price in comparison with other depth cameras, and high robustness.
Gravitational-Wave Burst Signals Denoising Based on the Adaptive Modification of the Intersection of Confidence Intervals Rule
Authors: Lopac Nikola , Lerga Jonatan , Cuoco Elena
Published: December 2020

Gravitational-wave data (discovered first in 2015 by the Advanced LIGO interferometers and awarded by the Nobel Prize in 2017) are characterized by non-Gaussian and non-stationary noise. The ever-increasing amount of acquired data requires the development of efficient denoising algorithms that will enable the detection of gravitational-wave events embedded in low signal-to-noise-ratio (SNR) environments. In this paper, an algorithm based on the local polynomial approximation (LPA) combined with the relative intersection of confidence intervals (RICI) rule for the filter support selection is proposed to denoise the gravitational-wave burst signals from core collapse supernovae. The LPA-RICI denoising method’s performance is tested on three different burst signals, numerically generated and injected into the real-life noise data collected by the Advanced LIGO detector. The analysis of the experimental results obtained by several case studies (conducted at different signal source distances corresponding to the different SNR values) indicates that the LPA-RICI method efficiently removes the noise and simultaneously preserves the morphology of the gravitational-wave burst signals. The technique offers reliable denoising performance even at the very low SNR values. Moreover, the analysis shows that the LPA-RICI method outperforms the approach combining LPA and the original intersection of confidence intervals (ICI) rule, total-variation (TV) based method, the method based on the neighboring thresholding in the short-time Fourier transform (STFT) domain, and three wavelet-based denoising techniques by increasing the improvement in the SNR by up to 118.94% and the peak SNR by up to 138.52%, as well as by reducing the root mean squared error by up to 64.59%, the mean absolute error by up to 55.60%, and the maximum absolute error by up to 84.79%.
Ego or Eco? Neither Ecological nor Egoistic Appeals of Persuasive Climate Change Messages Impacted Pro-Environmental Behavior
Authors: Kesenheimer Jana Sophie , Greitemeyer Tobias
Published: December 2020

Based on the ‘Inclusion Model of Environmental Concern’, we tested whether daily messaging intervention increases participants’ pro-environmental behavior (PEB). In a two (time: pre vs. post, repeated measure) × three (condition: egoistic appeals, ecological appeals, control group) experimental design, two hundred and eighteen individuals received either daily messages containing egoistic appeals for action to prevent climate change (e.g., preventing personal consequences of released diseases in melting arctic ice), ecological appeals (e.g., ecological consequences of melting glaciers), or no messages (control). PEB was assessed via self-reports and donations to an environmental organization. Neither of the appeals had an effect on the two dependent measures. Irrespective of experimental conditions, self-reported PEB was higher in the post- compared with the pre-test. Overall, the present results do not provide support for the effectiveness of a daily messaging technique. Instead, it appears that ‘being observed’ is the more effective ‘intervention’. Implications for how to foster PEB are discussed.

Authors: Ortega Jairo , Moslem Sarbast , Tóth János , Péter Tamás , Palaguachi Juan , Paguay Mario
Published: December 2020

The Park and Ride (P&R) system is a set of facilities available to private vehicle users to transfer to public transportation in order to complete their journey. The location of the facilities is determined by the purpose for which they have been created, for example, to reduce traffic in the central business district (CBD), reduce pollution, or increase the use of public transportation. Thus, a set of six main criteria and 19 sub-criteria are considered that are particularly important for decision-makers about the location of P&R facilities in a city. In order to identify which criteria are relevant, a method belonging to the multiple criteria decision is needed. The central point of this study is to evaluate the problem of the location of the facilities of the P&R system according to the point of view of the experts. For this aim, the Best Worst Method (BWM) is adopted to estimate the location of the facilities of the P&R system. The questionnaire survey has been designed estimated by ten transport experts in the related field. The recently created BWM was conducted. The results highlighted that “accessibility of public transportation” is the most important aspect of the problem of the location of P&R facilities. The results obtained provide greater accuracy in the location of facilities problem than the pure analytic hierarchy process method (AHP).

Published: December 2020

Education is of key importance to achieve the Sustainable Development Goals (SGDs), particularly now that the COVID-19 pandemic threatens the progress made toward a more inclusive, peaceful, fair, and prosperous society. In this research study, students of the bachelor’s degree in Pedagogy receive a specialized training that addresses the SDGs through Information and Communication Technologies (ICT) referring to computers and digital technologies. In particular, the training addresses the SDGs through Educational Robotics (ER). The aim of the training course is twofold: first, to reinforce the students’ Teacher Digital Competence (TDC), defined as teachers’ ICT competence and didactic and methodological skills; and second, to train them in the integration of SDGs in ER educational projects. This paper presents a case study in which qualitative and quantitative methods are implemented. The objectives of the study are to investigate the students’ level of TDC and examine their ability to integrate SDGs in ER projects. The research instruments employed are the COMDID-A questionnaire, a lesson plan template, and a lesson plan evaluation rubric. Among the most prominent findings, it is shown that the training enabled the students to work on sustainability in a cross-curricular manner and successfully develop ER projects centered on different SDGs. These conclusions will encourage teacher education institutions to integrate SDGs in their curriculum.

Authors: Kulisz Monika , Kujawska Justyna
Published: December 2020

Planning is a crucial component of short- and long-term municipal waste management. Establishing the relationships between the factors that determine the amount of waste generated by municipalities and forecasting the waste management needs plays a fundamental role in the development of effective planning strategies and implementation of sustainable development. Artificial Neural Network employed for verifying the forecasts pertaining to the amount of rainfall in Poland were presented in the studies. The proposed models included selected explanatory indices in order to reflect the impact of social, demographic and economic factors on the amount of generated waste. Mean squared error (MSE) and regression value (R) are used as indices of efficiency of the developed models. The ANN models exhibited high accuracy of forecasts at high R values (R = 0.914, R = 0.989) and low MSE values. Derived from the socioeconomic data for 2003–2019, the model predicts that the future waste generation in 2024 will increase by 2%. The results indicate that the employed ANN models are effective in predicting the amount of waste and can be considered a cost-effective approach to planning integrated waste management systems.
Quantitative Measure of Sustainability for Water Distribution Systems: A Comprehensive Review
Authors: Lee Seungyub , Kim Joong Hoon
Published: December 2020

This work provides a comprehensive review of the quantitative measures of sustainability proposed for water distribution systems (WDSs) and their sustainable development. After a comprehensive literature review, eighteen studies overall, either clearly proposing quantitative measures of sustainability (three studies) or highlighting sustainable development (fifteen studies), were selected for a closer review. All three measures showed either a lack of applicability or were missing important aspects of sustainability. Additionally, they have not been thoroughly validated by demonstrating the measures under acceptable scenarios/conditions. The reviewed sustainable development practices showed that energy usage and greenhouse gas emissions, life cycle costing, and reliability were widely used to evaluate environmental, economic, and social impacts, respectively. The two primary recommendations made based upon reviews were to: (1) consider balancing usage (cost) and gain (benefit), rather than impacts; (2) consider indirect (cascading/consequential) interactions. Overall, existing measures of sustainability and sustainable development practices in WDSs must be advanced to accommodate a focus on restorative systems, as well as to maximize benefits and enable multidisciplinary and broader analyses.

Published: December 2020

The article attempts to determine the effect of perceived flood risk, based on identified flood hazard zones, on the level of activity in the market of land property designated for housing developments in the historical town of Sandomierz, Poland. The study employed graphical, analytical, quantitative methods, and spatial analyses with GIS tools. The proposed methodology, involving spatial interpolation of the phenomenon (Kernel Density Estimation (KDE) and Inverse Distance Weighting (IDW)) and an expert opinion survey, facilitates the assessment of the market activity in towns where transactions are scarce. Trade in property is lower in areas at risk of flooding than for the remaining parts of the town. The potential flood hazard zone affects both the activity of the property market and the average prices of land. The study demonstrated that both a flood and flood risk affect the levels of market activity and the prices of residential land. However, this impact differs at various times and locations and is greater immediately after a flood. Properties located in the most attractive location within an area are characterised by a greater sensitivity to this risk.

Published: December 2020

The virion proteins of Kaposi sarcoma-associated herpesvirus (KSHV) were initially characterized in 2005 in two separate studies that combined the detection of 24 viral proteins and a few cellular components via LC-MS/MS or MALDI-TOF. Despite considerable advances in the sensitivity and specificity of mass spectrometry instrumentation in recent years, leading to significantly higher yields in detections, the KSHV virion proteome has not been revisited. In this study, we have re-examined the protein composition of purified KSHV virions via ultra-high resolution Qq time-of-flight mass spectrometry (UHR-QqTOF). Our results confirm the detection of all previously reported virion proteins, in addition to 17 other viral proteins, some of which have been characterized as virion-associated using other methods, and 10 novel proteins identified as virion-associated for the first time in this study. These results add KSHV ORF9, ORF23, ORF35, ORF48, ORF58, ORF72/vCyclin, K3, K9/vIRF1, K10/vIRF4, and K10.5/vIRF3 to the list of KSHV proteins that can be incorporated into virions. The addition of these proteins to the KSHV virion proteome provides novel and important insight into early events in KSHV infection mediated by virion-associated proteins. Data are available via ProteomeXchange with identifier PXD022626.

Authors: Zapor Michael
Published: December 2020

The Severe Acute Respiratory Syndrome Coronavirus (SARS-CoV-2) that emerged in December 2019 as the causative agent of Coronavirus 2019 (COVID-19) and was declared a pandemic by the World Health Organization in March 2020 has several distinctive features, including extensive multiorgan involvement with a robust systemic inflammatory response, significant associated morbidity and mortality, and prolonged persistence of viral RNA in the clinical specimens of infected individuals as detected by Reverse Transcription Polymerase Chain Reaction (RT-PCR) amplification. This review begins with an overview of SARS-CoV-2 morphology and replication and summarizes what is known to date about the detection of the virus in nasal, oropharyngeal, and fecal specimens of patients who have recovered from COVID-19, with a focus on the factors thought to contribute to prolonged detection. This review also provides a discussion on the infective potential of this material from asymptomatic, pre-symptomatic, and convalescing individuals, to include a discussion of the relative persistence and infectious potential of virus in clinical specimens recovered from pediatric COVID-19 patients.
Effect of Zr Impregnation on Clay-Based Materials for H2O2-Assisted Photocatalytic Wet Oxidation of Winery Wastewater
Authors: Guimarães Vanessa , Teixeira Ana R. , Lucas Marco S. , Peres José A.
Published: December 2020

UV-activated Zr-doped composites were successfully produced through the impregnation of Zr on the crystal lattice of different clay materials by a one-step route. Fixing the amount of Zr available for dopage (4%), the influence of different supports, submitted to different chemical treatments, on the photocatalytic activity of the resulting Zr-doped pillared clay materials (PILC) was assessed. Both chemical characterization and structural characterization suggest that the immobilization of Zr on montmorillonite and PILC structures occurred through isomorphic substitution between Si and Zr in the tetrahedral sheet of the clay material. This structural change was demonstrated by significant modifications on Si-OH stretching vibrations (1016 cm−1, 1100 cm−1 and 1150 cm−1), and resulted in improved textural properties, with an increase in surface area from 8 m2/g (natural montmorillonite) to 107 m2/g after the pillaring process, and to 118 m2/g after the pillaring and Zr-doping processes ((Zr)Al-Cu-PILC). These materials were tested in the UV-photodegradation of agro-industrial wastewater (AIW), characterized by high concentrations of recalcitrant contaminants. After Zr-dopage on AlCu-PILC heterogeneous catalyst, the total organic carbon (TOC) removals of 8.9% and 10.4% were obtained through adsorption and 77% and 86% by photocatalytic oxidation, at pH 4 and 7, respectively. These results suggest a synergetic effect deriving from the combination of Zr and Cu on the photocatalytic degradation process.
Water and Climate Governance in Deltas: On the Relevance of Anticipatory, Interactive, and Transformative Modes of Governance
Authors: Triyanti Annisa , Hegger Dries L. T. , Driessen Peter P. J.
Published: December 2020

Deltas worldwide have been experiencing pressures and challenges exacerbated by climate change. An explicit focus on deltas is lacking in various bodies of literature, although present in those bodies focusing on the resilience of social-ecological systems. However, overall, literature relevant for addressing water and climate governance in deltas is arguably still fragmented, leading to knowledge gaps and unexplored opportunities with regards to the development of delta-oriented governance strategies. To address this knowledge gap, we conducted a systematic literature review focusing on six bodies of literature relevant to delta governance up to and including the year 2019. The results show that scholarly interest in developing transformative pathways has increased sharply over the last few years. We derived seven key governance problems and five governance solutions for resilient deltas. We found that the predominant focus is still on technocratic approaches, with limited recognition of the political dimension and few forward-looking studies. In conclusion, we suggest stimulating the development and application of more anticipatory, transformative, and interactive modes of governance to help steer the transformation to resilient and sustainable deltas. We end with suggestions for systematic, interdisciplinary, and forward-looking empirical-analytical research.

Authors: Kim Seon Woo , Jung Donghwi , Choung Yun-Jae
Published: December 2020

Climate polarization due to global warming has increased the intensity of drought in some regions, and the need for drought estimation studies to help minimize damage is increasing. In this study, we constructed remote sensing and climate data for Boryeong, Chungcheongnam-do, Korea, and developed a model for drought index estimation by classifying data characteristics and applying multiple linear regression analysis. The drought indices estimated in this study include four types of standardized precipitation indices (SPI1, SPI3, SPI6, and SPI9) used as meteorological drought indices and calculated through cumulative precipitation. We then applied statistical analysis to the developed model and assessed its ability as a drought index estimation tool using remote sensing data. Our results showed that its adj.R2 value, achieved using cumulative precipitation for one month, was very low (approximately 0.003), while for the SPI3, SPI6, and SPI9 models, the adj.R2 values were significantly higher than the other models at 0.67, 0.64, and 0.56, respectively, when the same data were used.

O objetivo deste artigo é compreender como são construídas, por meio de discursos de autorrepresentação, as identidades dos usuários do aplicativo de relacionamentos Grindr, utilizado principalmente por homens gays (ou bissexuais), com a finalidade de marcar encontros. Busco, especificamente, analisar as representações (homos)sexuais que esses sujeitos fazem de si mesmos e do outro em seus perfis virtuais, averiguando o confronto entre a escolha de certas identidades e o silenciamento de outras através das estratégias de negociações identitárias.  A escolha desse aplicativo se deu em razão ao seu intenso crescimento de usuários e pela expressiva popularidade que ele adquiriu nos últimos anos, visto que os sujeitos, caso queiram, podem disponibilizar fotografias e informações básicas sobre si para criarem um tipo de “autoidentidade”. O percurso metodológico utilizado para a análise dos dados busca romper com as fronteiras e limites disciplinares, em direção a uma perspectiva inter/trans/indisciplinar. Amparo-me, para isso, nas perspectivas epistemológicas dos Estudos da Linguagem e da Teoria Crítica do Discurso, dos Estudos Culturais, da Antropologia e da Sociologia.

Published: December 2020

The aim of this study is to determine the effect of ethical leadership behavior on counterproductive behaviors. Data were obtained using the survey technique. The sample of the study consists of 252 employees who work in four - and five - star hotels in Istanbul. According to the results of the analysis, it is found that the "abuse" dimension is the most powerful dimension in order to explain counterproductive work behavior. Counterproductive business behavior is negatively affected by ethical leadership behaviors.

Authors: Arıkan Saltık Işıl
Published: December 2020

El objetivo del estudio es examinar el efecto del cinismo organizacional en la satisfacción laboral de los empleados en las organizaciones públicas de turismo. El cinismo organizacional, que es la creencia de los individuos de que las organizaciones están privadas de la unidad moral y que los principios de equidad, honestidad y sinceridad se sacrifican en favor de los intereses organizacionales, pueden afectar la satisfacción laboral de los empleados. Este estudio contribuye a la investigación empírica limitada al investigar los impactos del cinismo organizacional y sus dimensiones en la satisfacción laboral de los empleados de las organizaciones públicas de turismo donde los recursos humanos administrados efectivamente tienen importancia tanto como en las empresas privadas.

Los resultados de la regresión indican que, excepto en la dimension comportamental otras dimensiones del cinismo organizacional tienen impactos negativos y significativos en la satisfacción laboral. Se encontró que el cinismo cognitivo tiene el de mayor efecto seguido del cinismo emocional en la satisfacción laboral. Además, en el estudio se examinaron las diferencias en el cinismo organizativo por algunas características demográficas y ocupacionales del empleados. El estudio concluye con una discusión sobre las implicaciones y limitaciones de la gestión.

El Turismo en un Mundo Incierto: desafios para el siglo XXI en un contexto post COVID19
Authors: Korstanje Maximiliano E.
Published: December 2020

Desde su adopción en el turismo, el término gobernanza ha hecho referencia a la reducción de la pobreza y a la pauperización de ciertos colectivos o grupos étnicos que históricamente habían sido relegados y desprotegidos por sus propios estados Nacionales. Con el advenimiento del terrorismo y de los conflictos étnicos, los hacedores de políticas públicas vieron en la noción de la gobernanza un fértil campo para los estudios que quieren explicar no sólo las fallas de la planificación racional y el desarrollo, también los beneficios del turismo para mejorar las condiciones de vida de la población local. El presente ensayo reflexiona sobre el rol del turismo y sus desafíos en un mundo complejo donde el miedo y el placer por la muerte del Otro son dos valores importantes de un nuevo capitalismo. El covid-19, lejos de ser un evento fundante, parece re-afirmarse en una lógica donde la hospitalidad se encuentra en su leyó de muerte.
Integralna ekologija i franjevci
Authors: Tomašević Luka
Published: December 2020

Autor je članak podijelio na sljedeći
način: uz uvod i zaključak, rad se dijeli na sljedeća poglavlja: 1. Kratka povijest ekološke problematike u
Crkvi; 2. Misao pape Franje; 3. Doprinos franjevačke tradicije. Već je
na konferenciji Ujedinjenih naroda o okolišu u Rio de
Janeiru kardinal Martini uime pape Pavla VI. govorio o ekološkim problemima u
svijetu, a papa Ivan Pavao II. na svjetski Dan mira 1990. godine uputio je
poruku Mir s Bogom Stvoriteljem – mir s
cjelokupnim stvorenjem. Papa Franjo također se bavi ekološkom
problematikom, nadahnut sv. Franjom Asiškim. Franjevačka paradigma nadilazi
današnju fragmentarnu viziju svijeta koja vlada u znanosti i koja naglašava
sukob umjesto suradnje. Ekološka filozofija trebala bi shvatiti da različitost
ne onemogućuje relaciju, već je čini još autentičnijom jer smo, istina, svi
različiti, ali ovisni jedni o drugima.
“I’ll tell”: Beckett, Geulincx y la voluntad de fracasar
Authors: Duchovny Malena
Published: December 2020

En el presente trabajo buscamos rastrear la influencia que tuvo la Ética del filósofo Arnold Geulincx en los Fizzles de Samuel Beckett, a los cuales consideramos representativos de la poética beckettiana tardía ya que las constantes referencias a textos anteriores del autor irlandés dan la idea de una condensación de su obra. Para esto, analizamos las primeras referencias que Beckett hace a Geulincx luego de haber leído su Ética y mostramos el cambio que se da en la poética beckettiana, especialmente en relación con la idea de la voluntad humana subsumida a la voluntad divina, como quienes caminan hacia el este a bordo de un barco que se dirige al oeste. Beckett reemplaza a la voluntad de Dios por el azar, pero acepta que no hay manera de expresar la voluntad de la conciencia. Así, su poética se modifica: el esfuerzo negativo se transforma en una voluntad de crear aunque el fracaso sea inevitable. Esto lo vemos especialmente retratado en “Three Dialogues”, donde Beckett realiza su famosa aseveración acerca de la imposibilidad de expresarse. Finalmente, procedemos a un análisis de los Fizzles en sí y reparamos en la insistencia en el fracaso voluntario en la forma y el contenido de estas prosas.
ОСОБЛИВОСТІ МІЖМОВНОЇ ІНТЕРФЕРЕНЦІЇ РОСІЙСЬКОМОВНИХ АМЕРИКАНЦІВ
Authors: Васильева О. В.
Published: December 2020

Стаття присвячена аналізу особливостей міжмовної інтерференції, що виникає в процесі вивчення російської мови як іноземної. Проаналізовано різні погляди на термін «міжмовна інтерференція», представлені в лінгвістичній науковій літературі. Автором названо причини виникнення інтерференції і ефективні шляхи її подолання. Виявлено типи інтерферентних явищ: недодіфференціація ознак (при наявності диференціальних ознак в нерідній мові і відсутності в рідній мові); сверхдіфференціація (при наявності диференціальних ознак в рідній мові і відсутності їх в іноземній); реінтерпретація. У статті виділено ключові фактори, поєднання яких дозволяє досягти більш вільного володіння іншомовною вимовою. Описано явище інтерференції на фонетичному, лексичному, морфологічному і синтаксичному рівнях: на фонетичному рівні названо типові помилки в артикуляції звуків російської мови, заміщення окремих звуків, зміна наголосів, неточності в інтонуванні речень; виявлено труднощі в засвоєнні окремих граматичних категорій, наприклад, категорії роду, відмінка, які відсутні в англійській мові; звернуто увагу на порушення норм мови на синтаксичному рівні, проаналізовано складності в структурі речень, зумовлені вільним порядком слів; визначено особливості інтерференції на лексичному рівні – використання багатозначних слів, труднощі з використанням омофонів, акцентовано увагу на використанні фразеологізмів. Представлено результати опитування американців, які вільно володіють російською мовою і проживають у місті Херсоні, про лінгвістичні труднощі, що виникли в процесі вивчення російської мови. Аналіз особливостей рідної мови дозволяє прогнозувати типові помилки, поява яких можлива в мовленні американців.
