Fast structural dynamic modeling and analysis for horizontally folding wing
Authors: Ni Y. , Zhang W. , Lv Y.
Published: September 2021

To investigate the structural dynamic characteristics of a folding wing effectively, a fast structural dynamic modeling approach is proposed. Firstly, the interface compatible relationship of the traditional fixed interface component modal synthesis method is modified, and the internal force of the interface is completely expressed in the structural dynamic equation, so that the influence of the connection stiffness on the wing structure dynamics can be considered. Then, on the basis of the fixed interface component modal synthesis method, the main mode of fixed-loaded interface is introduced to establish the mixed-loaded interface component modal synthesis method, which makes it feasible to accurately reflect the influence of elasticity and inertia of fuselage and outer wing on inner wing. The structural dynamics modeling method based on two different kinds of component modal synthesis method analyzed and deduced in detail. The application of component modal synthesis method in the fast structural dynamics modeling of folding wing is achieved. The whole program is compiled in MATLAB. At the same time, the dynamic characteristics of the folding wing with different folding angles, different connections and different connection positions is investigated. The results of the method proposed in this paper are compared with the results of the repeated finite model established in MSC.NASTRAN to verify the effectiveness from the aspects of natural frequency and vibration mode.

Published: September 2021

The land surface in the Padang City is thought to be experiencing a continuous relative subsidence due to natural processes and man-made activities. Factors that affect land subsidence include earthquakes, sea level rise, infrastructure development, sediment transport, and excessive use of groundwater sources. The purpose of this research is to map the rate of land subsidence which is processed from the Sentinel 1-A radar, satellite imagery using the Differential Synthetic Aperture Radar (DInSAR) method. The data used are two pairs of Sentinel-1A level 1 Single Looking Complex (SLC) imagery which were acquired in 2018 and 2019. Image processing is carried out by filtering and multilooking techniques on Synthetic Aperture Radar (SAR) images. The following process changes the phase unwrapping to the ground level phase using phase displacement. Land subsidence in 2018–2019 from DInSAR processing reached -10.5 cm / year. The largest land subsidence occurred in North Padang with an average of -7.64 cm/year. Land subsidence in the Padang City, which is located near the estuary, is due to the nature of the alluvial sediment material. The use of Sentinel 1 SAR remote sensing data can provide important information in the context of mitigating land subsidence in the Padang City. Therefore, we need the right policies to handle future land subsidence cases. Land subsidence mapping is one of the factors that determine the vulnerability of coastal areas to disasters

Published: September 2021

This study aims to determine the fulfillment of the needs of victims of natural disasters through the implementation of a social assistance distribution system for victims of natural disasters that occurred in Padang Pariaman Regency. This research was conducted using a qualitative descriptive approach that describes the social assistance distribution system for victims of natural disasters with an orientation towards meeting the needs of the victims. It can also be categorized as exploratory research which studies a number of cases of aid distribution towards meeting the needs of victims. Data collection was carried out by direct interviews with officials who were directly involved in the distribution of aid, direct observation to victims of natural disasters, document review, and Focus Group Discussion (FGD). Data analysis, using descriptive-qualitative techniques. The results of the study conclude that the current social assistance distribution system for victims of natural disasters has not yet achieved the goal, namely meeting the needs of victims of natural disasters. Long mechanisms and procedures, incompatible with regional conditions, and the absence of potential synergy of personnel are factors between the ineffectiveness of the social assistance distribution system for victims of natural disasters in Padang Pariaman Regency. The results of the study recommend that in formulating a policy for the distribution of social assistance systems for victims of natural disasters, it should begin with periodic mapping of disaster events and the needs of victims, involving victims as recipients of assistance in accordance with the mandate of Article 26 of Law No.24 of 2007 concerning National Disaster Management. Local governments should be given full authority to implement policies in accordance with regional conditions and disaster characteristics. The granting of this authority should be included in the regional autonomy law regarding the rights of regional governments in the case of natural disaster management, specifically included in local regional regulations.

Authors: Driptufany Dwi Marsiska , Guvil Quinoza , Syafriani Desi , Arini Dwi
Published: September 2021

The water catchment area also indirectly impacts on flood control for areas that are lower than it because rainwater does not fall to the lower areas but is absorbed as groundwater. Increased development of Padang City will be inversely proportional to the reduction in water catchment areas and become an area that is impermeable that makes rainwater stagnate on the surface and flood occurs. The development of remote sensing technology and geographic information systems has made it possible to study the spatial patterns of potential water catchment areas in a wide range, including mapping the potential of water catchment areas in Padang City. This study aims to analyze the condition of the availability of water catchment areas for controlling water management and flood disasters in Padang City based on data on spatial parameters such as rainfall data, slope, soil type maps, and land use obtained from Landsat 8 OLI imagery data. This study uses the scoring and overlay method with the Geographical Information System. The results show that the condition of the water catchment area in the western part of Padang City have been critical, reaching 18.29% of the total area of ​​Padang City, this is due to land use that has undergone a change of function. If the water infiltration condition worsens (critical), it gives more opportunities for flooding and inundation. Thus the areas with the potential for water absorption which are categorized as critical and very critical in the research location can be said to be areas that are potentially prone to flooding and inundation, because the ground surface is no longer able to absorb water. Monitoring the potential of water catchment areas is one form of flood mitigation efforts.

Factors affecting boxwood blight spread under landscape conditions
Authors: LaMondia J. A. , Allan-Perkins E. , Kodati S.
Published: September 2021

We investigated the spread of boxwood blight in a simulated landscape under conducive natural conditions from 2017 to 2019. We used strict sanitation to greatly reduce or eliminate spread by contact. Movement of the pathogen from an infected source plant was limited to one plant, likely spread by means of water splash. Plants were mulched with composted hardwood chips and mulching likely was primarily responsible for limiting spread to only the adjacent plant. Boxwood (Buxus spp.) cultivar susceptibility and fungicide spray programs influenced the incidence of spread and severity of disease; in 2018 and 2019 the more susceptible cultivar had higher disease incidence and severity, respectively, than less susceptible cultivars. Fungicide application only caused a small reduction in disease incidence in 2018. We also demonstrated that spores in clumps could survive extended dry conditions, indicating the importance of sanitation procedures on reducing spread. This experiment demonstrates that boxwood blight can be controlled in a landscape by following best management practices including cultural, sanitation, host susceptibility and fungicide application tactics.

Use of Routine Leaching Fraction Testing to Guide Irrigation at a Container Nursery
Authors: Million Jeff B. , Yeager Thomas H.
Published: September 2021

Efficient irrigation during container plant production is difficult to achieve as irrigation is scheduled daily or multiple times per day to maintain an adequate supply of water in the limited substrate volume. Leaching fraction (container drainage/water applied) testing is one strategy to monitor and adjust irrigation to limit excessive container drainage. We compared an automated irrigation schedule based on routine leaching fraction testing and weather (LFI) with a nursery's traditional irrigation practice (TIP). Compared to TIP, LFI reduced water applied in four of five sprinkler-irrigated trials without a notable growth affect; LFI increased water applied in a fifth trial but plant growth was also increased. Compared to TIP, LFI reduced water applied in all three micro-irrigated trials but also reduced growth in one of the trials. LFI reduced water applied by an average of 21% [57.8 vs. 73.1 kL·ha−1· d−1 (15,300 gal/acre/day) or $3,000 ha−1yr−1 ($1,200/acre/year) at a pumping cost of $0.53/kL ($0.20/1000 gal). We concluded that the greater economic benefit of water savings was to provide increased capacity for additional production under consumptive water use limitations rather than to reduce the unit cost of production.

Análisis y propuesta del diseño de la silla de ruedas de propulsión manual a partir de la percepción y satisfacción de los usuarios con discapacidad motriz
Authors:   , Rojas Anaya José David
Published: September 2021

La presente investigación buscó analizar el diseño de la silla de ruedas de propulsión manual y proponerle mejoras y adecuaciones a partir de la satisfacción y percepción de los usuarios con discapacidad motriz de la Ciudad de México. Por lo anterior, este estudio muestra resultados cuantitativos y cualitativos referentes a la satisfacción y percepción de los usuarios de silla de ruedas en relación con esta ayuda técnica. Como objetos de estudio, se consideraron dos tipos de silla de ruedas de propulsión manual: la de estructura rígida y la de estructura plegable. Para obtener los resultados cualitativos se emplearon una serie de entrevistas de forma presencial en las que se obtuvieron hallazgos de tipo exploratorio donde se evidenciaron algunos factores emocionales y factores físicos de la silla de ruedas relacionados con la insatisfacción del usuario. En cuanto a la parte cuantitativa, los resultados fueron obtenidos por medio de dos herramientas, que fueron aplicadas de manera presencial y virtual, esta última debido a la pandemia del COVID-19. La primera herramienta, consistió en el cuestionario QUEST 2.0 (Quebec User Evaluation of Satisfaction with Assistive Technology) que tuvo como propósito mostrar de forma numérica el grado de satisfacción de los usuarios con respecto a diferentes características de usabilidad de la silla de ruedas. La segunda, fue la Escala de Diferencial Semántico, en este caso, utilizada para la cuantificación de la percepción de los usuarios hacia su silla de ruedas. Una vez fue recolectada y analizada la información descrita anteriormente, se procedió a la identificación de los requerimientos de diseño, que contribuyeron al planteamiento de las adecuaciones que fueron fue modeladas en SolidWorks y que posteriormente fueron sometidas a un análisis de elementos finitos en el mismo software. Finalmente, la silla de ruedas con sus respectivas adecuaciones fue evaluada mediante la Rueda Emocional de Ginebra con el objetivo de medir las reacciones emocionales de los usuarios a partir de la interacción visual con esta. De la evaluación, se obtuvieron reacciones emocionales positivas en comparación con la silla de ruedas de estructura rígida y a la de estructura plegable.

Published: September 2021

El objetivo fue evaluar de forma descriptiva la relación entre las expectativas de autoeficacia, malestar emocional y estrategias de afrontamiento en pacientes con fibromialgia, considerando los componentes físicos y psicosociales de la experiencia de dolor, y sobre todo la necesidad de clarificar la relación entre ellos para mejorar la adaptación a cualquier situación de dolor crónico. En el estudio participaron 100 mujeres pacientes de fibromialgia del Instituto Provincial de Rehabilitación del Hospital Universitario Gregorio Marañón de Madrid quienes completaron la siguiente batería de cuestionarios: la Escala de ansiedad y depresión en hospital (HADS), el Inventario de estrategias de afrontamiento en dolor (CPCI), y la Escala de autoeficacia en dolor crónico (CPSS). Los resultados muestran que la autoeficacia correlaciona inversamente con el malestar emocional (ansiedad y depresión). Con relación a las estrategias de afrontamiento, la persistencia en la tarea se relaciona significativamente con las expectativas de autoeficacia, mientras que esta variable lo hace de forma inversa con la depresión. Descansar y protegerse se relacionan de forma negativa con la autoeficacia. Estos resultados sugieren que las expectativas de autoeficacia juegan un papel importante en el uso de estrategias positivas de afrontamiento y en el funcionamiento emocional adecuado en pacientes con fibromialgia
El efecto Mateo en niños con Dificultades Específicas de Aprendizaje de las Matemáticas
Authors: Blanco Pérez Margarita , Bermejo Vicente
Published: September 2021

En el presente trabajo se intentó determinar si la presencia de Dificultades Específicas de Aprendizaje en Matemáticas (DAM) se asociaba con la caída de las puntuaciones en las pruebas psicométricas empleadas para valorar el Cociente Intelectual (CI) que con el paso de los cursos se observa en estos niños, tal como sostienen algunos autores con las Dificultades en Lectura y Matemáticas. Además, se evaluó si las diferencias en CI se relacionaban con rendimientos matemáticos igualmente diferentes. Para ello se comparó el CI de 12 niños con DAM escolarizados en 1º de Educación Primaria con el de 20 niños con DAM de 3º de Educación Primaria. Por otro lado, se contrastó el CI de estos niños DAM con el de dos muestras control sin DAM de las mismas cohortes. Entre otros resultados se observó que el CI de los niños DAM de mayor edad (3º curso) era significativamente más bajo que el de los niños más jóvenes, mientras que no existían diferencias entre los niños sin DAM. Además, la presencia de un CI alto o bajo no suponía siempre un rendimiento matemático igualmente alto o bajo en los escolares.
Global processing deficit in Alzheimer’s disease
Authors: Blanca María J. , Rodrigo Teresa , Bendayan Rebecca
Published: September 2021

Several studies of Alzheimer’s disease (AD) reveal an impaired capacity to integrate visual elements into global pictures, leading to a deficit in global processing of visual information. The aim of this paper was to explore global and local processing in people with AD at non-advanced stage. The Global and Local Attention Test (AGL; from the original Spanish: AGL-Atención global y local) was administered to a group of 100 participants with a mean age of 75.36 years. Fifty of them were AD patients at a mild or moderate stage, while the remainder comprised healthy elders. The AGL provides two scores that indicate speed and accuracy in analyzing global and local figures. Participants had to indicate the figures where the target appeared at either global or local levels in a divided attention task. The results showed lower accuracy in the AD group compared with controls. Also in the AD group, and in line with previous findings, accuracy in detecting the target was much lower at the global level than at the local level, thereby confirming the expected deficit in global processing associated with AD. This deficit did not vary according to sex or age.

Published: September 2021

El objetivo del presente estudio es conocer si existen diferencias en patrones de personalidad y síndromes clínicos en función de la rehabilitación o recaída en el juego patológico. Para ello, se ha llevado a cabo un seguimiento a 176 jugadores de un centro de rehabilitación cuya terapia está centrada en grupos de autoayuda de dos años de duración, dividida en tres fases de ocho meses cada una. La rehabilitación se consigue con la finalización de las tres fases, considerándose recaída inmediata el abandono en la primera, o tardía si el abandono es en la segunda fase. Se realizó una evaluación previa al tratamiento con el Inventario Clínico Multiaxial de Millon. Se analizan las diferencias en patrones de personalidad y síndromes clínicos entre los participantes que recaen en una de las fases y los que alcanzan la rehabilitación. El 61,93% de los participantes alcanzan el éxito terapéutico. Los resultados muestran que sólo la personalidad antisocial presenta diferencias significativas, presentando menor puntuación los participantes que finalizan el tratamiento. Por otro lado, no se encontraron diferencias en el número de personas que se rehabilitan en función de su perfil clínico previo.

Authors: Navarro Raúl , Yubero Santiago
Published: September 2021

El presente estudio fue diseñado para conocer las conductas de comunicación online en una muestra de preadolescentes (10-12 años, n=812). Se analizó el efecto de la ansiedad social, las habilidades sociales y las experiencias de cibervictimización sobre la comunicación online. La comunicación online comprendía ítems relacionados con el tiempo empleado, las plataformas utilizadas, las personas con las que interactúan y los motivos para conectarse a la red. La ansiedad social fue evaluada mediante la Escala de ansiedad social para niños revisada, las habilidades sociales a través de la subescala del Cuestionario Matson y la cibervictimización mediante la Escala de Victimización a través de Internet. Los resultados mostraron que el grupo con altas habilidades sociales y baja ansiedad emplean más tiempo comunicándose en Internet y utilizan más los mensajes instantáneos para hablar con los amigos. Por el contrario, la conducta online del grupo con alta ansiedad social y bajas habilidades está más motivada por el deseo de hacer amigos. Las víctimas de ciberbullying emplean más tiempo online, utilizan más las salas de chat y se comunican más con desconocidos. Estos hallazgos sugieren que, a pesar de los riesgos, Internet también permite mantener y ampliar la red social existente.

Como consecuencia de la crisis financiera global, la tasa de desempleo en España ha alcanzado dimensiones históricas. En este sentido, el presente estudio tiene como objetivo examinar las repercusiones psicológicas del desempleo en los trabajadores que lo han padecido como consecuencia de la crisis. Para ello se ha comparado el bienestar psicológico de una muestra de trabajadores del sector de la construcción, clasificados en cuatro grupos diferentes de acuerdo a su situación laboral: desempleados (n = 57), trabajadores temporales (n = 54), trabajadores indefinidos (n = 52) y trabajadores autónomos (n = 56). Los resultados del ANOVA muestran que los desempleados experimentan mayor deterioro psicológico que los trabajadores que conservan su empleo, si bien sólo se constatan diferencias estadísticamente significativas entre los trabajadores desempleados y los trabajadores temporales. Finalmente, se discuten las implicaciones teóricas y prácticas de los resultados encontrados.
Protocolo preliminar "Teatinos" de evaluación y diagnóstico funcional de la voz
Authors: Adrián José A. , Casado Juan C. , González Mercedes
Published: September 2021

La voz es uno de los principales mecanismos usados en comunicación humana. Ésta depende de estructuras anatomo- fisiológicas bien definidas, cuya alteración morfológica o funcional provoca alteraciones laríngeas que pueden ocasionar una patología denominada disfonía. La disfonía es la causa de muchas de las bajas laborales que se producen anualmente entre personas que han de usar frecuentemente de la voz en el trabajo, tales como los maestros y profesores. También afecta a personas que hacen un uso incorrecto de su voz, lo que puede ocasionarles con el tiempo una fatiga vocálica y el consecuente trastorno disfónico. El tratamiento de este tipo de patologías ha de conllevar una evaluación otorrinolaringológica, logopédica y psicológica previa que determine la causa de dicho trastorno. El protocolo “Teatinos” es una propuesta de evaluación y diagnóstico sencilla y asequible que mide los principales parámetros que influyen en el uso de la voz. Su fin es dotar a los alumnos y profesionales del diagnóstico y rehabilitación de estas patologías de herramientas fiables y homogéneas que les ayuden en su práctica clínica.
Las características personales en la experiencia de dolor y en proceso de afrontamiento
Authors: Ramírez Maestre Carmen
Published: September 2021

Se trata de un trabajo de revisión acerca de cómo una serie de determinantes estables afectan a la experiencia de dolor y a las respuestas del sujeto al mismo. En concreto, se repasa lo que la literatura teórica y empírica dice acerca de cómo las características personales del sujeto con dolor crónico (sexo, edad y variables de personalidad como el neuroticismo, la extraversión y el optimismo disposicional) pueden determinar tanto la percepción de dolor como las estrategias de afrontamiento utilizadas, ejerciendo así un efecto diferencial en la adaptación del sujeto a la situación de dolor crónico. El número de estudios de este tipo con pacientes de dolor crónico es muy escaso. Sin embargo, se contemplan también algunas publicaciones acerca de la influencia de dichas características personales en el ámbito del estrés y del dolor experimental y agudo.

Aims

Percutaneous left atrial appendage occlusion (LAAO) is an alternative nonpharmacological therapeutic option for stroke prevention in patients with NVAF. However, no data exist on potential LAAO candidates’ prevalence among ‘real-world’ NVAF patients. This study aimed to investigate the indications for LAAO in hospitalized patients with comorbid nonvalvular atrial fibrillation (NVAF).

Methods

This is a post-hoc analysis of the MISOAC-AF (Motivational Interviewing to Support OAC-AF, ClinicalTrials.gov: NCT02941978), randomized controlled trial, which enrolled NVAF patients hospitalized for any reason in a tertiary cardiology department. In this analysis, patients with a history of major bleeding or stroke under OAC therapy were considered to have a strong indication for LAAO.

Results

A total of 980 patients with NVAF were studied (mean age 73.9 ± 10.9 years, 54.7% men). Prior major bleeding occurred in 134 (13.7%) patients (intracranial bleeding in 1%, upper and lower gastrointestinal bleeding in 6.4 and 8.9%, respectively). A total of 58 (5.9%) patients experienced an embolic stroke while being treated using OAC. Overall, either of these events was prevalent in 173 (17.7%) patients, denoting a strong indication for LAAO.

Conclusion

Almost one out of six patients hospitalized with comorbid NVAF may be considered eligible for percutaneous LAAO for stroke prevention.

Value-at-Risk Estimation of Equity Market Risk in India
Authors: Jitender
Published: September 2021

The value-at-risk (Va) method in market risk management is becoming a benchmark for measuring “market risk” for any financial instrument. The present study aims at examining which VaR model best describes the risk arising out of the Indian equity market (Bombay Stock Exchange (BSE) Sensex). Using data from 2006 to 2015, the VaR figures associated with parametric (variance–covariance, Exponentially Weighted Moving Average, Generalized Autoregressive Conditional Heteroskedasticity) and non-parametric (historical simulation and Monte Carlo simulation) methods have been calculated. The study concludes that VaR models based on the assumption of normality underestimate the risk when returns are non-normally distributed. Models that capture fat-tailed behaviour of financial returns (historical simulation) are better able to capture the risk arising out of the financial instrument.

The study examines the asymmetric impact of oil price and electricity consumption on economic growth in Nigeria between 1981 and 2018 using the Non-Linear Autoregressive Distributed Lag (NARDL) model. Results reveal that falling and increasing oil prices as well as gross capital formation affect economic growth in Nigeria negatively and significantly in the short-run, while electricity consumption affects economic growth positively and significantly in the short-run. In the long-run, the impact on economic growth of negative changes in oil price is negative and insignificant, while positive changes in oil price have a positive but insignificant impact on economic growth. The impact on the economic growth of electricity consumption remains positive but insignificant while that of gross capital formation is positive and significant. The results suggest that both in the short and the long run positive changes in oil price have greater impact on the economic growth than negative oil price changes. Capital formation is a significant determinant of Nigerian economic growth both in the short and the long run.

Published: September 2021

This paper investigates whether stock markets respond to disease pandemic referencing the case of COVID-19 in Nigeria. The paper employs three cointegrating regression models: Fully Modified Ordinary Least Squares, Dynamic Ordinary Least Squares, and Canonical Cointegrating Regression to analyse the effect of growth in total COVID-19 confirmed cases and related deaths in Nigeria and across the globe from 27 February 2020 to 4 September 2020 on the stock market performance. Key findings support the presence of long-run association between stock market returns and COVID-19 in Nigeria. The stock market is found to respond negatively to both domestic and global growths in total confirmed cases and deaths of COVID-19. Consequently, affected businesses in Nigeria should be assisted and bailed out by the government through practices such as tax filing, subsidies, targeted spending, and credit.

Published: September 2021

This paper examines the effects of environmental responsiveness on firm value in Nigeria and provides an insight into the feasibility of corporate entities engaging with the United Nations’ sustainable development agenda, without compromising their wealth creation agenda. Secondary data were gathered from annual reports and audited accounts of 83 quoted non-financial firms for three years covering the period of 2016–2018. Thereafter, a regression analysis using the Ohlson value relevant model for price valuation was done. Results of the empirical analysis confirm the positive influence of value relevance of book values, earnings per share, alongside environmental responsiveness and firm size on the firm value of Nigerian firms, while leverage is inversely related. Remarkably too, firms with higher values tend towards being environmentally responsive. Impliedly, there is an empirical evidence of reverse causality between firm value and environmental responsiveness.

This paper explores the role of entrepreneurial orientation in addressing upward mechanisms of Indian immigrant workers in rural areas. To achieve this purpose, an empirical analysis was carried out to investigate how entrepreneurial orientation may affect mechanisms of professional transition. Precisely, we managed direct interviews among Indian workers (through the support of cultural mediators), local actors (like public and private advisors) and Italian entrepreneurs. Our funding suggests the presence of three Indian workers in Italy (simple workers, intrapreneurs, entrepreneurs), characterised by different entrepreneurial profile acting as engine or barrier to what we have labelled as “upward transition”. Immigrant entrepreneurs play a relevant role in Italy and in our point of view, it is of paramount importance to allow them to access to rural development policies, knowledge, training and education upgrading.
Nostalgia, Sensations and Local Products in Rural Tourism Experiences in a Portuguese Schist Village

Rural tourism has attracted increasing attention in recent decades. It responds to new market demands, some of which driven by a nostalgic quest for a ‘rural idyll’, as well as the need of many European rural territories to find new sources of income and development. Local products represent a relevant asset for appealing to rural tourist experiences, enhancing local identity and regional economies. Based on a study of the rural tourist experience as lived by visitors of a Portuguese schist village, the present paper analyses the role of nostalgia and sensory experiences in leading to tourists’ purchase of local products, using a conditional process analysis. Results confirm this link and also show that tourists seem to be more affected by these dynamics than excursionists. Implications of results for management and development of rural territories involving tourism and sales of local products are further discussed.
Understanding Phenological Stages of Pomegranates vis-à-vis Flowering and Fruiting Regulation

Published: September 2021

A thorough understanding of plant behavior at different growth stages is of paramount importance for fruit quality improvement, the regulation of production periods, and reduced fruit production costs. There are as many as three waves of flowering in evergreen pomegranate cultivars – i.e., during the spring, rainy, and autumn seasons. However, for securing enhanced production of superior quality fruits as well as profit to the growers, crop regulation is required. This can be achieved by forcing the tree to rest at a particular stage and by producing abundant blossoming and quality fruits during any one of the three flushes. Observations on phenological phases would help in understanding the dates of specific stages of crop development, which in turn enable the growers to plan, organize, and carry out timely schedules of agronomic practices such as irrigation, fertilization, and crop protection. Therefore, there is a need to evaluate the response of pomegranate under different environmental conditions to identify a suitable flowering season to produce a better quality of fruits with consistent yield, and to enable standardization of management practices for optimum production based on phenological stages.
Self-assessment of football referees on their educational influence on children aged 9–12 during a sports competition
Authors: Płoszaj Katarzyna , Firek Wiesław
Published: September 2021

Proper use of the educational potential of sports depends on the entities organizing children’s sports competitions (coaches, parents, referees). Particularly important is their awareness of the purposefulness and legitimacy of actions taken. Numerous studies have been devoted to the role of the coach and parents in providing children and young people with positive sporting experiences. In contrast, the referee has often been overlooked. The behavior of the referees during the match is also important for young players. Assuming that referee-player interactions have a major contribution to educational influence, the purpose of this study was to explore the opinions of soccer referees refereeing matches of children aged 9 to 12 years about their interactions with players in terms of emotional support, game organization, and instructional support. It was also decided to verify whether referees’ self-assessment of their educational function is influenced by experience. The research was conducted among 116 referees licensed by Mazovian Football Association who referee matches of children aged 9–12 years (Orliki and Młodziki categories) in the Masovian Voivodeship in Poland. To assess the referee-players educational interaction, a questionnaire survey was developed. These interactions are present in three domains: emotional support, game organization and instructional support. The results showed significant differences between referees’ self-assessments in the three domains. Referees rated their educational interactions with players higher in the domain of emotional support than the instructional support. Moreover, the results indicated that there was no differences in the referees’ self-assessment between the groups distinguished by more experienced in the domains of emotional support and game organization, while less experienced referees rated the quality of their educational interactions in the instructional support domain higher than those more experienced. The main conclusion of the research is the postulate to introduce pedagogical and psychological issues into the referee training.
Temple and Paradise. Some Remarks on the Dynamics of Sacred Place
Authors: Mihăilă Alexandru
Published: September 2021

In ancient eastern literature, the creation of the world could be connected to the building of the temple dedicated to the creator deity. Creation and temple-building represented for the ancient mentality an obvious continuity that legitimized the cult itself. A further connection could be drawn between the primeval world and the Temple Mount of Jerusalem. The present paper analyzes the intertwining elements of the temple on the holy mountain and the garden of paradise, the original place of pleasure in the presence of God, taking into account the primeval stories of Ezekiel and Genesis. Some elements of the biblical stories will be discussed as part of the history of traditions. For studying the concept of paradise, the "rst chapters of the Hebrew Bible are for now to be skipped, because, as it will be assumed, earlier accounts are found in the book of Ezekiel.
