Habichuelas y prácticas de cultivo en dos lugares de los llanos costeros de Puerto Rico
Authors: James S. Beaver  , Obed Román-Hernández  , Luis E. Rivera
Published: October 2020

De 1983 a 1985 se hicieron experimentos de campo en dos localidades de Puerto Rico para comparar la respuesta de tres genotipos de habichuela (Phaseolus vulgaris L.) a diferentes prácticas de cultivo. Los genotipos de habichuela variaron en hábito de crecimiento y en susceptibilidad a acamarse. Se utilizó un diseño de bloques completos aleatorizados con un arreglo de parcelas divididas con tres repeticiones. Las parcelas enteras consistieron de dos distancias entre surcos (0.5 y 1.0 m.). Las subparcelas consistieron de un arreglo factorial de tres densidades de siembra (6.6, 13.2, y 19.8 semillas/m.) y tres genotipos de habichuela. Con los tres genotipos se obtuvieron los mayores rendimientos en parcelas con 0.5 m. entre surcos y una densidad de siembra de 19.8 semillas/m. Los mayores rendimientos se debieron a un aumento en el número de vainas/ha. El genotipo 2W-33-2 produjo los mayores rendimientos, a pesar de que el acamado fue mayor que en los demás genotipos. En Fortuna los rendimientos de los genotipos fueron mayores de 2,000 kg./ha. cuando se sembraron en surcos de 0.5 m. de ancho. Con relación al índice de cosecha, en Fortuna no hubo diferencias significativas tanto en distancia entre surcos como en densidad de siembra. Por el contrario, en Isabela, el índice de cosecha disminuyó cuando se aumentó la densidad de siembra. La altura de la planta y el peso de 100 semillas no mostraron diferencias significativas al variar la distancia entre surcos y la densidad de siembra. En Fortuna el acamado fue mayor cuando la densidad de siembra se aumentó.

Authors: Qureshi Javed Akhtar , Ababs Naeem , Khan Garee , Khan Hawas , Shah Kausar Sultan , Ali Sajid
Published: October 2020

In this study, optimal operation parameters for the extraction of copper (Cu) from malachite ore of the Shigar region of Gilgit-Baltistan were identified. The effects of some operational parameters on Cu recovery has been identified. The pulp density (25%) and other parameters are kept constant throughout the process. Crushing and grinding were carried out and obtained the desired size range of flotation. The sample of malachite ore has been overwhelmed using roll and jaw crushers. The final product of roll crusher was finer than that of jaw crusher. It has been observed that more fines were obtained with increasing grinding time. After a certain time, there is little effect on grinding. With decreasing particle size, copper recovery increased. At 50 µm the recovery is almost 90% while at 325µm, recovery decreased to 46%. With increasing pH copper recovery is increased and at 12.5% pH, maximum recovery (up to 90%) has been achieved. The optimum parameters for the copper extraction from malachite ore of the Shigar valley are the pH 12.5%, 50-micron particle size and grinding time of 25 minutes.

Published: October 2020

Soil erosion is a serious environmental problem faced by district Chakwal. Unpredictable short term and high intensity rainfall, improper cultivation and deforestation have accelerated the soil erosion in the district. The agricultural productivity of the study area can be enhanced by understanding, estimating and controlling the root causes of soil erosion. This study was undertaken to estimate and spatially represent the rate of average annual soil erosion in Chakwal using GIS/RS techniques. The soil erosion was estimated using Universal Soil Loss Equation (USLE) model. To find out parameters of USLE, ASTER GDEM of 30 m resolution was used to estimate slope length and elevation of the study area. Landsat 8 satellite imagery of year 2019, was used to prepare land use map using supervised classification. Soil map with texture and geomorphology was used to identify soils of study area and rainfall data of last 7 years was also studied. Finally, the soil loss has been computed using raster calculator of ArcGIS 10.2 software. The average annual soil loss was predicted up to 268,619 tons/acre/year, of which maximum soil erosion was occurring near the steep slopes and river channels. It is necessary to adapt sustainable land management practices to reduce the risk of further soil erosion, by adopting rainwater harvesting and choosing right crops for suitable soil types.

Authors: Tuyet Tran Thi Bach , Khang Nguyen Duy
Published: October 2020

Research on the use of Flipgrid in the language classrooms has focused on its effects of online video-mediated communication tools, learners’ attitudes, and perceptions; nonetheless, not much research has recently been conducted about the influences of the Flipgrid app on EFL learners’ speaking anxiety. Therefore, this research aimed at investigating whether Flipgrid helps the EFL high school learners reduce their anxiety in learning English speaking and determine the learners’ attitudes towards its usages. The research followed a combination of a quasi-experimental method and a mixed-method with the participation of 60 EFL tenth-grade learners in a high school in the Mekong Delta. Three research instruments namely the modified Foreign Language Classroom Anxiety Scale (FLCAS), the questionnaire, and the interviews were employed in this study. The findings showed that there was a decrease in EFL high school learners’ level of anxiety in learning English speaking after experiencing Flipgrid. Moreover, the majority of the learners also showed their positive attitudes towards the use of Flipgrid in learning English speaking and expected that Flipgrid should be employed frequently to make learning English speaking become more motivating.

Published: October 2020

Otizm spektrum bozukluğu, doğuştan gelen ya da yaşamın ilk yıllarında ortaya çıkan ve bireylerin gelişimini etkilediği için “gelişimsel bozukluk” olarak da adlandırılan bir nörogelişimsel farklılıktır. Beynin yapısını ve işleyişini etkileyen çeşitli sinir sistemi sorunlarından kaynaklanan otizm spektrum bozukluğuna neyin neden olduğu kesin olarak bilinmemekle birlikte genetik bir alt yapısının olduğu düşünülmektedir. OSB tanısı konulan bireylerde; beslenmede problem yaşama, nesneleri döndürme, öfke nöbeti, birbirini tekrarlayan hareketler, yoğun konsantrasyon, alışkanlıkların dışına çıkamama, ses ve ışığa karşı hassasiyet, belirli alanlara takıntılı olma derecesinde ilgi duyma gibi sorunlar görülmektedir. Erken tanı, tedavi ve eğitimde OSB li bireylerin hayata kazandırılması ve topluma uyum sağlamasında etkin bir rol oynamaktadır. Zamanında başlanan doğru bir eğitim programıyla OSB’li bireyler diğer akranları ile aralarındaki gelişim geriliği farkını büyük oranda kapatabilmektedirler. Dolayısıyla günümüz toplumunda OSB li bireylerin eğitimi ve tedavisinin yanı sıra bu bireyleri topluma katmak adına toplumun da bilinçlenmesi gerekmektedir. Bu makalede OSB hakkında içerik araştırılmış ve grafik tasarım alanı olan dergi ilanı tasarımları ile OSB li bireylerin toplumda yaşadığı sıkıntılara dikkat çekilerek otizm hakkında toplumsal farkındalık oluşturulmaya çalışılmıştır.

Neural tube defects, their implications and solutions in Muslim society
Authors: Muhammad Fayyaz  , Arshad Khushdil  , Shehla Baqai
Published: October 2020

Abstract

Neural Tube Defects (NTDs) are serious congenital abnormalities and most of them are incompatible with life. The extremely debilitating quality of life, if one survives, calls for actions to prevent such sufferings.  Experts agree on the role of Folic Acid in primary prevention of NTDs, yet, despite best efforts, the use of Folic Acid has reduced NTDs by only 50%. These cases too can be prevented by employing secondary preventive measures. These involve timely interruption of pregnancy -- a decision which, in addition to a medical judgment, is based on ethics, social, cultural and Muslim religious value systems in Pakistan. Indeed, it is a complex issue but empathic understanding and strong co-ordination, once established between different disciplines, can help parents to decide and opt for necessary secondary prevention by interruption of malformed foetus within the given time frame mandated by medical and religious authorities.

El hemitruncus arterioso es una cardiopatía congénita rara caracterizada por el origen anómalo de alguna de las ramas de la arteria pulmonar a partir de la aorta ascendente. En la mayoría de los casos su diagnóstico se realiza durante la infancia; además, por su elevada morbimortalidad es extremadamente inusual su evolución asintomática y supervivencia hasta la etapa adulta. Presentamos el caso de un varón de 30 años con antecedente de cierre quirúrgico de persistencia del conducto arterioso en la infancia, que cursó asintomático hasta hace un año, y se le diagnosticó hemitruncus arterioso a partir de episodios recurrentes de hemoptisis.
A Short Analysis of Quality and Performance in The Radio Segment of Romanian Mass-Media
Authors: Burtic Daniel
Published: October 2020

More than one hundred years ago, once the radio appeared, mass media started to be more pronounced. Mass-media market diversified its offer, and the quality and creativity of economical agents determined a reassert on the competition and performance scale. For our research in mass media field, we distinguish two vital aspects of economic quality and performance: audience and financial results. In this section we will try to follow the evolution of the main players from the Romanian audiovisual market on the radio segment, taking into account these two variables: audience and financial results. Quality and performance in mass-media are two elements desired on one side by mass-media producers: the owners and employees from this field, and on the other side, by mass-media customers: audience and publicity buyers. We analyse the aspects of quality and performance in Romanian media industry in o period of rapid change. The changes are on multiple levels, and the most accentuated regards the consumer’s behaviour, market environment, technological changes and legal regulations. The changes in the consumer behaviour are determined by their perceptiveness towards the digital world. Quality and performance in mass-media are two desired elements, on one side by the mass-media producers: owners and employees in the field, and on the other side by mass-media customers: audience and publicity buyers.
Advice for a Communicative Learning Environment
Authors: Santoro Cerice
Published: October 2020

Currently the Philippines is the last country in Asia implementing a ten year education plan providing education until tenth grade before students reach university level. The education change will aid future Filipino professionals to compete globally since it is the recognized standard throughout the world. However, with expanding pressure for EFL teachers to implement new programs and systems it has left a gap between students being proficient academically and communicatively at the same time. The issue continues to increase since inappropriate implementation of activities leave students perceiving the communicative approach as frivolous and unproductive. As a result students do not appreciate an active learning environment in the classroom.
The examination of the test of English as a foreign language (TOEFL):
Evident disparities between world Englishes and standard English
Authors: Kim Caroline
Published: October 2020

While many English Language Learners (ELLs) embark on a path towards higher education in universities centered around Standardized English, they must undergo rigorous training to prepare for these demanding TOEFL exams. Students that have been exposed to World Englishes, or lingua francas, for communicative purposes are now asked to abandon these English varieties to assume the elevated importance of the Standardized form of English implemented across universities around the world. This paper analyzes the juxtaposition and negotiation of these languages as learners are often encumbered with not only linguistic barriers but cultural hindrances that contribute to identity displacement. As language is deeply entrenched in one’s cultural background, it is necessary to reflect on how these English proficiency exams negate the learner’s L1 along with the unique qualities that they strongly identify with.
Research in Writing Instruction and Assessment: Current and needed research to improve student writing
Authors: Outcault Hill MJ , Caldwell Robert
Published: October 2020

Discussions among educators at almost any level will invariably result in one point of agreement: students at all levels are under-prepared in writing skills. Unfortunately, this is a conclusion that also predominates much of the research literature on the improvement of student writing as well. Despite the importance attached to high-stakes academic writing skills, research has contributed little insight about the challenges students face with academic writing tasks. Llosa, Beck, and Zhao (2011) point out that the National Commission on Writing in America’s Schools and Colleges found that this lack of understanding of the writing process was so significant that they identified writing as, the “Neglected ‘R’ (National Commission on Writing, 2003; Llosa, Beck and Zhao, 2011). In the following paper, authors Caldwell and Outcault Hill present a broad review of the areas of research into the writing process and assessment of writing and suggest areas where further research is needed. Their discussion focuses on 1) Research related to the influence of Cognitive function on the writing process, 2) Research into teaching various genres such as exposition, argument, narrative, analysis, and creative writing, 3) Research on the assessment of writing, and finally, 4) Research on alternative teaching methods.
The level of psychological and docial adjustment among a sample of persons with learning disabilities in Asir Region in light of some variables
Authors: Khasawneh Mohamad
Published: October 2020

This study aimed at investigating the level of psychological and social adjustment in relation to the grade and type of learning disability among persons with learning disabilities in the Asir region. The study was applied to a sample of (350) students studying in schools in the Department of Education in Asir. The sample responded to the psychological and social adjustment scale developed as a tool of the study. The results showed that the level of psychological and social adjustment came with a medium degree, as well as the absence of statistically significant differences in the level of psychological and social adjustment students in the basic stage. In light of the results, the researcher recommended preparing awareness programs for teachers of learning disabilities to identify the various indicators that accompany the phenomenon of psychological and social adjustment for persons with learning disabilities. The study also recommends conducting more studies on psychological and social adjustment and its relationship to other variables, such as emotional intelligence.
Goya depois de Goya
Authors: Radünz Dennis Lauro
Published: October 2020

O procedimento de montagem do poema “Goya después de El Prado”, de Hebert Benítez, atualiza a Gravura # 43 de Francisco de Goya e, atravessado de heterocronia, incita a uma leitura do “princípio-atlas” (Georges Didi-Huberman) e da configuração do monstro como compossibilidade e mistura, desde a filosofia pré-socrática de Empédocles de Agrigento. A atribuição de valor, a causalidade, a periodização e, em especial, a heterocronia são substratos dessa cena de leitura que procura articular a gravura de 1799 e o poema de 1999 à noção de “desativação da autonomia” (Raúl Antelo) e, no percurso, encontra a heterocronia e a montagem da artista Leila Danziger, em sua exposição “Navio de emigrantes” (2018/2019).
Sobre o governo das memórias: aspectos de um domínio do real
Authors: Honesko Vinícius Nicastro
Published: October 2020

A partir de considerações sobre questões relacionadas à teoria da história, o presente ensaio analisa como a produção de uma narrativa historiográfica contém alguns aspectos que podem também ser detectados nos atuais modos de gestão de informações e governo político baseados em padrões da cibernética. Para tanto, num primeiro momento, expõe como as maneiras de operar na historiografia podem ser compreendidas a partir de uma poética do saber e, num segundo momento, entrelaça essa dinâmica aos padrões de gestão de probabilidades no âmbito das ciências físicas e sociais. Por fim, expõe como a produção de um real por meio do controle das probabilidades se tornou o eixo central para o domínio das experiências humanas em sua amplitude (desde a gestão das memórias às práticas de governo em sentido estrito).
Poesia segundo Paul Zumthor na canção "Metal contra as nuvens", de Renato Russo
Authors: Ozório Elisângela Maria
Published: October 2020

Paul Zumthor (1997; 2005; 2007) apresenta teorias e críticas acerca da poesia presente na canção. Para isso, o crítico vale-se do estudo sobre a poesia oral e passa a reconhecer que toda poesia possui, pelo menos, duas vozes que se conectam: a voz do eu poético e a voz do intérprete que executa a canção. A voz do intérprete incorpora a voz do eu poético, o que facilita a recepção da mensagem poética, já que tal prática precisa da performance que está contida na canção. Portanto, a performance figura como uma das ideias centrais do teórico, assim como ele a diferencia da pura recepção e assim como também define o que é canção. O artigo Poesia segundo Paul Zumthor na canção Metal contra as nuvens, de Renato Russo se dispõe a pensar a canção poética, usando a letra músico-poética Metal contra as nuvens (1991), do compositor e poeta Renato Russo. Além do mais, antes de adentrar nas proposições de Paul Zumthor, o artigo conta com os estudos de Octavio Paz (1982) para aclarar o que são a poesia e a palavra poética.

Authors: Trindade Leonardo Antônio , Magnani Vinicíus Medeiros , Ambrozini Marcelo Augusto , Antônio Rafael Moreira
Published: October 2020

Este estudo se propôs a avaliar o impacto da utilização de derivativos para fins de proteção (hedge) no risco das companhias de capital aberto negociadas na Bolsa de Valores de São Paulo ([B]3). A partir de uma amostra composta por 359 empresas analisadas entre os anos de 2010 e 2017 e separadas entre usuárias e não usuárias de derivativos por meio de variável dummy, foi empregada a metodologia de regressão de dados em painéis, tendo como variável dependente o risco e como variáveis independentes o uso ou não de derivativos, o tamanho, a alavancagem, o book-to-market e a liquidez. Os resultados obtidos pelos modelos passaram por testes de robustez e indicaram, assim como era esperado, que o uso de derivativos para hedge está acompanhado de uma redução no risco das companhias, assim como verificado em países desenvolvidos. Diante disso, este estudo poderá auxiliar na compreensão dos reflexos do uso de derivativos antes das alterações implementadas pela norma que regulamenta a contabilização e a divulgação dos instrumentos financeiros derivativos (IFRS 9), que passou a vigorar em 1º de janeiro de 2018. Além disso, o estudo contribui para que os gestores de empresas percebam o impacto da adoção de políticas de hedge no mercado acionário.

Solidarity or Distancing? How Official Status Influences Chinese Protestant Reactions to Repression
Authors: Doshay Harris
Published: October 2020

When facing state-backed repression, why do groups sometimes band together in solidarity and sometimes fail to do so? This study contributes to the literature on repression by studying how and why repressed groups react to repression, focusing on how registered civil society groups affect solidarity. Specifically, I trace the impact of the Chinese Communist Party's Cross Demolition Campaign on patterns of solidarity and victim blaming among Christian Churches. I further demonstrate conditions under which repressed group members become more fragmented and scattered rather than more unified. Based on evidence from sixty-four elite and mass interviews, I find that registered groups' legibility constrains their members, thus enabling dynamics of victim-blaming that hinder solidarity and further empowering the autocrat to divide and conquer potential opposition.

Abstract. An analytic transfer inverse model for Earth Polychromatic Imaging Camera
(EPIC) observations is proposed to retrieve the cloud-top pressure (CTP) with the
consideration of in-cloud photon penetration. In this model, an analytic equation
was developed to represent the reflection at the top of the atmosphere from above cloud, in cloud, and below cloud. The coefficients of this analytic equation
can be derived from a series of EPIC simulations under different atmospheric
conditions using a nonlinear regression algorithm. With estimated cloud
pressure thickness, the CTP can be retrieved from EPIC observation data by
solving the analytic equation. To simulate the EPIC measurements, a program
package using the double-k approach was developed. Compared to line-by-line
calculation, this approach can calculate high-accuracy results with a
100-fold computation time reduction. During the retrieval processes,
two kinds of retrieval results, i.e., baseline CTP and retrieved CTP, are
provided. The baseline CTP is derived without considering in-cloud photon
penetration, and the retrieved CTP is derived by solving the analytic
equation, taking into consideration in-cloud and below-cloud
interactions. The retrieved CTPs for the oxygen A and B bands are smaller
than their related baseline CTP. At the same time, both baseline CTP and
retrieved CTP at the oxygen B band are larger than those at the oxygen
A band. Compared to the difference in baseline CTP between the B band and
A band, the difference in retrieved CTP between these two bands is generally
reduced. Out of around 10 000 cases, in retrieved CTP between the A and B bands
we found an average bias of 93 mb with a standard deviation of 81 mb. The
cloud layer top pressure from Cloud–Aerosol Lidar and Infrared Pathfinder
Satellite Observations (CALIPSO) measurements is used for validation.
Under single-layer cloud situations, the retrieved CTPs for the oxygen
A band agree well with the CTPs from CALIPSO, the mean difference of which
within 5 mb in the case study. Under multiple-layer cloud situations, the
CTPs derived from EPIC measurements may be larger than the CTPs of high-level thin clouds due to the effect of photon penetration.

Published: October 2020

Abstract. The monthly Standardized Precipitation Evapotranspiration Index (SPEI) can monitor and assess drought characteristics with one month or longer drought duration. Based on data from 1961 to 2018 at 427 meteorological stations across the mainland China, we developed a daily SPEI dataset to overcome the shortcoming of coarse temporal scale of monthly SPEI. Our dataset not only can identify the start and end dates of drought events, but also can be used to investigate the meteorological, agricultural, hydrological and socioeconomic droughts with different time scales. In the present study, the SPEI data with 3-month scale were taken as a demonstration example to analyze spatial distribution and temporal changes in drought conditions for the mainland China. The SPEI data with 3-month scale showed no obvious intensifying trends in terms of severity, duration, and frequency of drought events from 1961 to 2018. Our drought dataset serves as a unique resource with daily resolution to a variety of research communities including meteorology, geography, and natural hazard studies. The daily SPEI dataset developed is free, open and persistent publicly available from this study. The dataset is publicly available via the figshare portal (Wang et al, 2020), with https://doi.org/10.6084/m9.figshare.12568280.
GO_3D_OBS – The Nankai Trough-inspired benchmark geomodel
for seismic imaging methods assessment and next generation 3D
surveys design (version 1.0)
Authors: Górszczyk Andrzej , Operto Stéphane
Published: October 2020

Abstract. Detailed reconstruction of deep crustal targets by seismic methods remains a long-standing challenge. One key to address this challenge is the joint development of new seismic acquisition systems and leading-edge processing techniques. In marine environments, controlled-source seismic surveys at regional scale are typically carried out with sparse arrays of ocean bottom seismometers (OBSs), which provide incomplete and down-sampled subsurface illumination. To assess and minimize the acquisition footprint in high-resolution imaging process such as full waveform inversion, realistic crustal-scale benchmark models are clearly required.The deficiency of such models prompts us to build one and release it freely to the geophysical community. Here we introduce GO_3D_OBS – a 3D high-resolution geomodel representing a subduction zone, inspired by the geology of the Nankai Trough. The 175 km x 100 km x 30 km model integrates complex geological structures with a visco-elastic isotropic parametrization. It is defined in form of a uniform Cartesian grid containing 33.6e9 degrees of freedom for a grid interval of 25 m. The size of the model raises significant high-performance computing challenges to tackle large-scale forward propagation simulations and related inverse problems. We describe the workflow designed to implement all the model ingredients including 2D structural segments, their projection into the third dimension, stochastic components and physical parametrisation. Various wavefield simulations we present clearly reflect in the seismograms the structural complexity of the model and the footprint of different physical approximations. This benchmark model shall help to optimize the design of next generation 3D academic surveys – in particular but not only long-offset OBS experiments – to mitigate the acquisition footprint during high-resolution imaging of the deep crust.
Coupling interactive fire with atmospheric composition and climate
in the UK Earth System Model

Published: October 2020

Abstract. Fire constitutes a key process in the Earth system (ES) being driven by climate as well as affecting the climate by changing atmospheric composition and impacting the terrestrial carbon cycle. However, studies on the effects of fires on atmospheric composition, radiative forcing and climate have been limited to date, as the current generation of ES models (ESMs) do not include fully coupled fires. The aim of this work is the development and evaluation of a fully coupled fire-composition-climate ES model. For this, the INteractive Fires and Emissions algoRithm for Natural envirOnments (INFERNO) fire model is coupled to the atmosphere-only configuration of the UK’s Earth System Model (UKESM1). This fire-atmosphere interaction through atmospheric chemistry and aerosols allows for fire emissions to influence radiation, clouds, and generally weather, which can consequently influence the meteorological drivers of fire. Additionally, INFERNO is updated based on recent developments in the literature to improve the representation of human/economic factors in the anthropogenic ignition and suppression of fire. This work presents an assessment of the effects of interactive fire coupling on atmospheric composition and climate compared to the standard UKESM1 configuration that uses prescribed fire emissions. Results show a similar performance when using the fire-atmosphere coupling (the online version of the model) when compared to the offline UKESM1 that uses prescribed fire. The model can reproduce observed present day global fire emissions of carbon monoxide (CO) and aerosols, despite underestimating the global average burnt area. However, at a regional scale there is an overestimation of fire emissions over Africa due to the misrepresentation of the underlying vegetation types and an underestimation over Equatorial Asia due to a lack of representation of peat fires. Despite this, comparing model results with observations of CO column mixing ratio and aerosol optical depth show that the fire-atmosphere coupled configuration has a similar performance when compared to UKESM1. In fact, including the interactive biomass burning emissions improves the interannual CO atmospheric column variability and consequently its seasonality over the main biomass burning regions – Africa and South America. Similarly, for aerosols, the AOD results broadly agree with MODIS and AERONET observations.
Statistical postprocessing of ensemble forecasts for severe weather at Deutscher Wetterdienst
Authors: Hess Reinhold
Published: October 2020

Abstract. This paper gives an overview of Deutscher Wetterdienst's (DWD's) postprocessing system called
Ensemble-MOS together with its motivation and the design consequences
for probabilistic forecasts of extreme events based on ensemble data.
Forecasts of the ensemble systems COSMO-D2-EPS and ECMWF-ENS
are statistically optimised and calibrated by Ensemble-MOS
with a focus on severe weather in order to support the warning decision management at DWD. Ensemble mean and spread are used as predictors for linear and logistic multiple regressions
to correct for conditional biases.
The predictands are derived from synoptic observations and include temperature, precipitation amounts, wind gusts and many more and are statistically estimated in a comprehensive model output statistics (MOS) approach.
Long time series and collections of stations are used as
training data that capture a sufficient number of observed events, as required for robust statistical modelling. Logistic regressions are applied to probabilities that predefined meteorological events occur.
Details of the implementation including the selection of predictors with testing for significance are presented.
For probabilities of severe wind gusts global logistic parameterisations are developed that
depend on local estimations of wind speed. In this way, robust probability forecasts for extreme events are obtained
while local characteristics are preserved. The problems of Ensemble-MOS, such as model changes and consistency requirements,
which occur with the operative MOS systems of the DWD are addressed.
Serialización de la ficción televisiva: el género policiaco español y la narrativa compleja. Cadenas generalistas (1990-2010)
Authors: Tous-Rovirosa Anna , Hidalgo-Marí Tatiana , Morales-Morante Luís Fernando
Published: October 2020

Se estudian las 36 producciones seriales de género policiaco de las cadenas generalistas españolas (1990-2010) mediante un análisis narrativo, a partir de la hipótesis de que los cambios observados están relacionados con las influencias extranjeras y van a resultar determinantes para la narrativa serial de calidad contemporánea. Los objetivos de la investigación son determinar si se produce la evolución del procedimental a la cop-opera melancólica, y cómo se produce y qué interrelación se observa con la modernización del relato televisivo. Entre los resultados, destaca que la estructura del procedimental deja de ser un impedimento para la serialización, que las analepsis como modo de resolución de los casos permiten que el procedimental y el serial se articulen, que el policiaco se mantenga como género en auge en la ficción televisiva contemporánea y proporcione numerosos títulos a las nuevas y viejas plataformas. Se ratifica la hipótesis planteada. La serialización del policiaco, la sofisticación en el uso de recursos narrativos y visuales, así como una clara influencia de las producciones extranjeras determinan la evolución del periodo analizado que se constata en la hibridación genérica y de formato, el subgénero forense y los recursos narrativos. La serialización coincide con el establecimiento del género en España en la segunda década analizada (2000-2010). La fragmentación visual de la trama acentúa una narrativa posmoderna. Se observa una narrativa en el policiaco cada vez más homogénea entre la ficción española y estadounidense, como La casa de papel (Netflix, 2017-). Las alteraciones temporales y la fragmentación del relato producen ficciones parecidas a un mosaico, y las transformaciones narrativas se usan para aumentar la vinculación de un espectador más activo.
Minimal sufficiency with covert even
Authors: Panizza Daniele , Sudo Yasutada
Published: October 2020

Exclusive particles (e.g. just) express exclusivity inferences by negating focus alternatives to the sentence they modify. Grosz (2012) observes that they can sometimes give rise to what he calls minimal sufficiency readings, which seem to affirm, rather than negate, focus alternatives. Grosz proposes to analyze them in terms of the rank-order reading, a kind of scalar reading of exclusive particles that is independently attested. Coppock & Beaver (2014) put forward a similar analysis based on their unified semantics for different uses of exclusive particles. We point out that these previous accounts fail to capture the distribution of minimal sufficiency readings, in particular, the relevance of distributivity, and propose an alternative analysis where the scalar component of the minimal sufficiency reading comes from a covert version of even, rather than from the exclusive particle itself. Empirical support for this comes from the generalization that an overt even can be added to sentences that have minimal sufficiency readings without changing the meaning, but not to sentences that do not allow for minimal sufficiency readings. We argue that our account not only captures the distribution of the minimal sufficiency reading, but also derives the inferences involved in the minimal sufficiency reading compositionally together with the standardly assumed semantics for exclusive particles and even.
