Determining Forms of Expressions of Food Violence in Venezuela
Authors: José Iciarte García María
Published: December 2021

In the present investigation, the existence of various forms of expression of food violence in Venezuela was determined, through the measurement of contextualized variables within the established classification. The existence and aggravation of forms of economic expression of food violence were determined, with a relative improvement in food availability but an increase in the difficulty of access: the basic food basket was located in December 2020 at $180.16, and the minimum wage at $6.35, which covers only 3.5% of the basic food basket. Additionally, a substantial increase in the use of the US dollar was determined, in parallel to the Venezuelan legal tender (Bolívar) as well as the introduction of the electronic currency “Petro”, which distorts the food access market and hinders the accessibility. Likewise, the effectiveness index for the delivery of food subsidies and the ability to satisfy the basic food basket through the food programs was determined. The existence of forms of moral expression of food violence was determined by observing in the respondents, high levels of dissatisfaction in the delivery criteria both in a general and community way and high levels of inappropriate perception of the use of propaganda or political advertising in the delivery of help with the no consulted use of the image of the beneficiaries. Forms of emotional expression of food violence were evidenced, showing high levels of dissatisfaction and uncertainty in the ability to purchase food, as well as high levels of anguish. Forms of cultural expression of food violence were determined, by determining changes in the ancestral and traditional eating pattern of the Venezuelan, as well as high measurements of dissatisfaction in the forced change in said pattern, as well as in the alteration of tastes and preferences expressed by the respondents have experienced. Sanitary forms of expression of food violence were evidenced, by determining considerable percentages in the consumption of basic products such as flour and sugar in bulk with ignorance of the brand and origin of the food and high levels of dissatisfaction with the realization of this type of consumption. No physical forms of expression of Food Violence were evidenced when the queues for food access were apparently stopped, and the use of body markings.

Published: December 2021

Copolymerization is a very important method in the synthesis of products having the physical and chemical properties sought in industrial sense. In this paper, the copolymerization of N-(4-nitrophenyl) acrylamide monomer with D-limonene was carried out and LIM-co-NPA copolymer was synthesized by free radical chain polymerization reaction. The structure of sustainable copolymer of limonene was chemically characterized by FT-IR, 1H-NMR spectroscopic techniques. In addition, thermal stability of copolymer investigated by TGA/DTG/DTA simultaneous thermal analysis methods. The spectroscopic results are compatible with the amide or limonene polymers synthesized in the literature. From the important thermal results of the sustainable copolymer, it has been found that the initial decomposition temperature is 226°C, and the maximum decomposition temperatures is 329°C, glass transition temperature at 261°C and crystallization temperature at 340°C. It can be said that this promising sustainable copolymer is suitable for other mechanical, physical and biological study and research fields.
Interaction of mid-latitude systems in the southern Hemisphere with southwest monsoon
Authors: KUMAR S.
Published: December 2021

The movement of cold fronts with associated westerly waves in the lower troposphere across southern Africa and adjoining southwest Indian Ocean during the months of May to August for the years 1977 to 1981 has been examined in relation to the chief features of southwest monsoon. The deep frontal systems which penetrate north or latitude 25° S cause considerable fluctuations in the intensity of south to north pressure ridge along the east coast of southern Africa and Mascarene high.

 

During the period of movement deep frontal systems from the west coast of South Africa to the Mozambique channel, the pressure index falls leading to decrease in cross equatorial flow. With further eastward movement of the system across Mozambique channel the pressure .index rises and causes increase in cross equatorial flow in Arabian Sea, strengthening equatorial westerlies and .increase in horizontal shear. The study has revealed a definite association between variation of pressure index with onset and various phases of the monsoon circulation. This association could be of help in understanding and forecasting of these monsoon features.

A study of large-scale vertical motion over West Africa
Authors: JEGEDE OLUWAGBEMIGA  O.
Published: December 2021

Three separately recorded cases of thundery weather over West Africa that occurred during the conduct of the West African Monsoon Experiment (WAMEX) of 1979, are investigated with the kinematic vertical p-velocity field. The scheme employed here is based on a least-squares-plane technique which has been desribed in Jegede and Balogun (1991), as a variant to the similar methods used by Kung (1972, 1973), and Pedder (1981).

 

The aim in this study is to demonstrate the practicability of the kinematic method for interpreting observed surface weather. In all the three cast-s, there was some consistency noted between the precipitation patterns and the computed vertical velocity fields within the sub-region.
Treands in atmospheric turbidity over India
Authors: SRIVASTAVA H. N. , DATAR S. V. , MUKHOPADHYAY B.
Published: December 2021

Annual mean values of the turbidity coefficients at Indian Background Air Pollution Monitoring Network' (BAPMoN) were compared for the periods 1973-1980and 1981-1985. It was found that there is a general increase of turbidity during the latter period at all the stations except at Kodaikanal and Pune, suggesting the effect of anthropogenic sources of pollution. Short term influence of volcanic eruptions were also discernible from the observations at Kodaikanal. Spectral analysis (FFT) at these stations brought out the predominant modes which could be explained on the basis of climatology and aerosol dispersion characteristics. The long term atmospheric turbidity observations (1973-1985) presented in this paper provide reliable data set for assessing the aerosol impact on radiation climate.
Precipitation chemistry over the Indian region
Authors: MUKHOPADHYAY B. , DATAR S.V. , SRIVASTAVA H.N.
Published: December 2021

The present study is based on the precipitation chemistry data from the Background Air Pollution Monitoring Network (BAPMoN) in the Indian region, for the period 1976-87. Sampling is made on an event basis and the pH and electrical conductivity of the samples are determined from filtered samples immediately after cessation of rain. The chemical analysis is performed on monthly mixed samples.

 

No trend is found in the pH of rainwater from background areas except at Allahabad, Pune and Visakhapatnam which suffer from sizable anthropogenic influences. The pH seems to be related more to NO3 ions compared to SO4-2 ions. A natural buffer appearing in the form of alkaline soil-derived species seems adequateat most places (except Mohanbari), in keeping a check on progressive acidification despite steady increase in concentration of nitrates. The ion balance cannot be achieved without including the presence of HCO3, which when done explains the observed electrical conductivity of rainwater. The interaction of marine aerosols with acid aerosols has also been studied for the marine regions in the Indian areas and reveals a substantial removal of chloride from sea-salt. Inland sources of NaCl have also been identified from the BAPMoN data.
Numerical simulation of a tropical Storm boundary layer
Authors: MANDAL J.C.
Published: December 2021

A model has been designed to study the surface boundary layer of a tropical storm. The numerical method consists of solving a two point boundary value problem for two systems of simultaneous non-linear differential equations by finite differences. A Stoke's stream function suitable to represent the flow both in interior and exterior regions of a tropical storm boundary layer has been developed. The advantage of the method is that the, boundary layer of the tropical storm can be studied starting from the outer region to the centre of the storm without neglecting non-linear terms. In addition, there IS no need for assumptions on the vertical profiles for tangential and radial velocities. The method is stable and converges within a few iterations. The flow above the friction layer is represented by a steady axisymmetric vortex in gradient balance. To investigate the effect of turbulence- on boundary layer characteristics, turbulence has been represented by four different variations of the eddy coefficient of viscosity with no slip boundary conditions. Computations have been performed 1aking 40-grid points in the vertical direction. It is observed that, if the eddy coefficient of viscosity is assumed to vary with the superimposed flow above the boundary layer, the solutions compare favourably well with observations. The solution also shows an outflow from the Inner core of the boundary layer which is necessary for creation of an eye of the storm.

A third degree polynomial surface fitting technique is adopted to compute the winds at different isobaric levels for the limited area domain from 35°E to 140°E and 30° S to 40oN for the month of June. The polynomial surfaces are fitted to the ratios of the monthly mean winds at different isobaric levels with the 850 hPa winds. The surfaces are fitted to the II and v components of the winds separately. The winds for the level are then reconstructed using the computed coefficients and observed wind at 850 hPa. The results of the technique are presented and discussed in the paper.
Monsoon onset and reservoir build up- A case Study for Hirakud
Authors: DHAR O. N. , NANDARGI S.S.
Published: December 2021

Onset of monsoon for each year of the period from 1961 to 1986 over the Upper Mahanadi basin has been studied taking into consideration the sharp increase in water levels of the Hirakud reservoir. This study has shown that .there are positive and negative time-lags in the arrival of monsoon run off into the reservoir. It has been seen that positive time lags are due to antecedent condition of the basin before the onset of monsoon while negative time-lag appears to be due to pre-monsoon thunderstorm activity which causes reservoir levels to increase before the onset of monsoon. Attempt has been made to discuss all these cases briefly. It has been seen that on  a majority of occasions monsoon runoff has reached the reservoir with a time-lag of 1 to 4 days.

Género y economía. Visibilización de la contribución de las mujeres en la agricultura familiar campesina en Paraguay. Año 2019
Authors: Ayala Dahiana , Achinelli Marcela
Published: December 2021

El artículo tiene como objetivo visibilizar la contribución de las mujeres en la agricultura familiar campesina y profundizar en la posibilidad que tienen las mismas, para acceder a la tierra, al crédito y a la tecnología, elementos generadores de desarrollo agrícola y por qué no, potenciadores de la autonomía económica de las productoras. Según (Kempf et al., 2019), las relaciones sociales y de producción presentes en la agricultura familiar campesina presentan contextos peculiares con relación a otros tipos de modelos de agricultura, uno de ellos, se refiere al trabajo de las mujeres y la magnitud de su contribución laboral en el establecimiento familiar, además de ser el pilar fundamental en la promoción de la seguridad alimentaria. La contribución económica y social de las mujeres en la agricultura familiar debe ser visibilizada y sujeta de políticas públicas para fomentar la igualdad de género en el contexto rural, significando esto, la generación de canales de participación de las mujeres en todo el desarrollo de la cadena de valor de la producción, impulsando el reconocimiento de las mujeres como actoras principales en la sostenibilidad del modelo agro-familiar y la soberanía alimentaria. En cuanto a la metodología, esta se desarrolla a partir de un análisis de la información cuantitativa, para lo cual se hizo uso de los datos secundarios proveídos por el Ministerio de Agricultura y Ganadería a través de la Dirección de Extensión Agraria (DEAg) con todos los programas que intervienen en la Agricultura Familiar y el Instituto Nacional de Estadística (DGEEC) con la Encuesta Permanente de Hogares (EPH) y la Encuesta de Uso del Tiempo (EUT), considerando para la Encuesta de Hogares una temporalidad de 10 años y, para el caso de la encuesta de uso del tiempo correspondiente al año 2016, así como el Censo Agropecuario Nacional (CAN) del año 2008. Entre los principales resultados se puede observar que las mujeres rurales padecen más fuertemente la pobreza, el 23,0% de ellas se encuenta en situación de pobreza y el 8,7% en condición de pobreza extrema, el 24% de las mujeres rurales trabaja como trabajadoras familiares sin percibir salario alguno, cuando se trata de explotación agropecuaria las mujeres se encuentran en mayor desventaja que los hombres, en el estrato de menos de una hectárea ellas representan el 36% de los productores, mientras que su participación se reduce al 15% en las de más de 1.000 hectáreas. El 44% de las mujeres inactivas rurales señala como razón principal el realizar labores del hogar, lo que concuerda con la mayor carga de trabajos no remunerados que ellas deben soportar, lo que significa mayores problemas de inserción al mercado laboral, mayor informalidad laboral y por ende la imposibilidad de desarrollar una vida plena, esto aunado a la poca participación que ellas tienen en los proyectos productivos y de financiamiento desarrollados por el gobierno y el casi nulo acceso a la propiedad de la tierra.

Policymakers have implemented a wide range of non-pharmaceutical interventions to fight the spread of COVID-19. Such policies vary substantially across regions or countries and, therefore, lead to variations in the diffusion patterns and fatality rates associated with this virus. We show that political decentralization is closely related to both the spread of COVID-19 and government responses to this spread. Specifically, we find that the disease tends to spread at higher speeds and result in more confirmed cases and deaths in countries that are more decentralized. We further show that it takes longer for more decentralized countries to implement any non-pharmaceutical interventions against COVID-19 and that more decentralized countries tend to adopt policies that are more targeted as opposed to being more generalized.

This study evaluates COVID-19 prevention and control policies. Based on the simulation, we compare the effects of two major policies: contact restriction and active treatment. Through regression and cluster analysis, we classified 169 countries and regions in the world into 10 groups, among which five groups accounted for the major proportion: the ones with the labels “CHN (China) mode,” “SE (South Europe) mode,” “ENE-SSA (East & North Europe and Sub-Saharan Africa) mode,” “US (United States) mode,” and “DEU (Germany) mode”). Differences in the effects of the prevention and control of COVID-19 in typical countries in each mode are comprehensively investigated. The conclusions of this study can be summarized as follows: First, contact restriction outperforms active treatment in curbing the spread of COVID-19. Second, “CHN mode” ranks the highest level of epidemic control and emphasizes epidemic prevention and control more than economic stimulus, which is the opposite of the “US mode”. Regression analysis reveals that the differences in epidemics worldwide are caused by policy differences among modes.

Análise de Sobrevivência dos Infectados pela COVID-19 no Estado do Rio Grande do Norte
Authors: Cavalcanti Gabriella da Silva
Published: December 2021

O presente estudo tem por objetivo investigar os determinantes da probabilidade e do tempo de sobrevivência dos infectados pelo novo coronavírus no estado do Rio Grande do Norte. Para tanto, foram utilizados os microdados oficiais de notificações de COVID-19 disponibilizados pela Secretaria de Estado da Saúde Pública (SESAP-RN) para estimar a função de sobrevivência, a partir do método de Kaplan-Meier (1958) e do modelo de risco de Cox (1972). Uma coorte de 13.738 casos confirmados de COVID-19 no estado entre as datas de 09/03/2020 a 12/06/2020 foi analisada. Os resultados apontaram uma queda na probabilidade de sobrevivência do infectado com o passar do tempo e que a idade, a preexistência de comorbidades como hipertensão arterial sistêmica, obesidade e doenças renais crônicas, a Região de Saúde e o bairro de residência influenciam a probabilidade de sobrevivência dos infectados pela COVID-19 no Rio Grande do Norte, corroborando com as evidências internacionais.
Los derechos culturales como libertades y su problemática en el Perú
Authors: Flores Paredes Jorge Luis
Published: December 2021

El presente artículo se basa en la tesis que sustenté en febrero de 2020 para optar el grado de magíster en Derechos Humanos, donde sostengo que los derechos humanos culturales, reconocidos en el primer párrafo del artículo 27 de la Declaración Universal de Derechos Humanos, son libertades de acuerdo con el concepto establecido por el jurista alemán Robert Alexy. Asimismo, se identifica en la normativa peruana de rango infraconstitucional una mayor atención por parte del Estado a sus obligaciones de protección del patrimonio cultural en desmedro de sus obligaciones de garantizar el pleno ejercicio de los derechos culturales en su naturaleza de libertad, que incluyen abstenerse de intervenir en el ejercicio de las prácticas culturales y en el acceso a los bienes culturales y a la par de realizar acciones para asegurar que existan condiciones para ambas prácticas. Se identifica la relevancia de esta tesis en la posibilidad de generar conciencia en funcionarios y servidores del sector cultura peruano sobre la naturaleza de libertad de los derechos culturales para la más idónea prestación de sus servicios.
Biología reproductiva e historia natural del Mero (Agriornis Lividus) en Chile central
Authors: Marín Manuel
Published: December 2021

Se estudió la biología reproductiva del Mero (Agriornis lividus) principalmente en un terreno privado en la zona central de Chile. En Chile la especie es más abundante bajo los 1.700m, pero puede llegar a los 2.600m, prefiriendo laderas arbustivas de áreas áridas a semi-áridas, con arbustos espinosos, con algunos cactus, pero de preferencia áreas con Chaguales (Puya sp). En la zona central de Chile su época de nidificación se extiende desde principios de septiembre a finales de octubre con una nidada por temporada, si pierde su nidada al parecer no los reemplaza. Su nido era en forma de taza, pero muy voluminoso, la parte exterior fue construida con palitos gruesos y con otras ramillas. Su interior cubierto con una gruesa capa intermedia de musgos y luego forrado con musgos o fibras vegetales suaves y ocasionalmente pelos de mamíferos (e.g., conejos o caballos) y raramente algunas plumas de otras aves. La posición de los nidos variaba entre 1,5 a 2,5 m de altura. Había una tendencia de preferir plantas espinosas para nidificar principalmente en Chaguales (Puya chilensis) y algunas veces en cactus como Quiscos Echinopsis chiloensis. Su nidada varió entre dos a cinco huevos, siendo la mayoría (47%) de tres huevos y (41,2%) (n=17) de cuatro huevos y la mayoría de los huevos (42%) era de la forma subelíptica. El color de los huevos era de un color base café cremoso con poco brillo casi opaco, con una gran variabilidad en el patrón de marcas. Aunque para algunos de los huevos el patrón de marcas era capirotado, con manchas irregulares, de un color rojizo, café-rojizo a negruzco, o café obscuro, estas marcas pueden ser: punteadas o moteadas. So observó que solo la hembra incubaba. El período de incubación fue en promedio de 20 días (19–21) y los pichones abandonaron el nido entre los 18–20 días. Los pichones eran empollados día y noche hasta la edad de 7 a 8 días y luego hasta los 15 días solo parcialmente. El periodo T10–90 fue de 13 días y la constante de crecimiento K = 0,338. El promedio de su masa corporal al eclosionar fue de 5,9 g y de su máxima masa fue 84,5 g a los 18 días de edad. La dieta de los pichones fue de un 82% entre lagartijas y orugas. Los adultos capturaban para los pichones principalmente presas del sotobosque (70,4%), y el resto presas arbóreas. Los adultos en la época post reproductiva se alimentaban principalmente de presas del sotobosque, pero en su dieta adicionalmente incluían frutas como Calafate (Berberis microphylla) y Maitén (Maytenus boaria). La mayor mortalidad 32,5% ocurrió en el estado de huevo. El éxito reproductivo total fue de 53,4%. Es un migrante austral parcial, como en otros cazamoscas en algunos años parte de la población se queda a nidificar. A finales de marzo y principios de abril es cuando se han detectado pequeños grupos pasando por el área y moviéndose hacia el norte.
The Speech Act of Apology by Filipino Call Center Agents
Authors: Sienes Mary Joy V , Catan Jasper Eric C
Published: December 2021

The Philippines is a global leader in business process outsourcing (BPO). Many foreign investors view the Philippines as a viable location for their call center operations due to the Filipinos' strength in English proficiency. This study focuses on inbound call center accounts that deal with a variety of call situations, ranging from information requests to difficult calls that require more time to handle, such as complaint calls. Since the goal of any business is customer satisfaction, this research aims to investigate how Filipino call center agents mitigate and reduce the liability and guilt towards customers. Results show that the 90 call center representatives have successfully produced 'perfect apologies' by providing all five strategies posited by Cohen et al. (1986) in most of their complaint calls. However, the sequence is distorted by emphasizing more on offering a repair. This leads to a recommendation that calls center training on apology be emphasized on building personal connections rather than a mechanical response to situations.
Design Optimization of Low-Pass Filter with Exponential Transmission Lines Using Differential Evolutionary Algorithm
Authors: Belen Aysu , Gunes Filiz , Belen Mehmet Ali , Moule Mahdi Ranjbar
Published: December 2021

In this work, Differential Evolutionary Algorithm (DEA), a novel and commonly used optimization algorithm in engineering problems, is applied for the design optimization of a low pass filter with exponential transmission lines. Basically the principle of DEA is similar to genetic algorithms techniques, however compare to meta-heuristic algorithms it has a much simpler algorithm structure and higher stability compare to its counterpart algorithms. For design optimization of low pass filter with exponential transmission lines, each of the transmission lines width and variation with its length are taken as an optimization variable for DEA. Firstly the unit microstrip transmission line model is chosen. After that, the optimal value of widths and lengths are obtained via DEA. The cost function of the DEA is based on the calculation of scattering parameters of candidate's solutions crossed the requested frequency bandwidth.

The spatio-temporal identifiers are obtained by using optical flow histogram and the structural similarity index from the videos that contain normal conditions. An artificial neural network, Selforganizing maps are used in modeling. The proposed system has been tested on the UCSD dataset.
Using Local Features in Face Recognition Systems
Authors: Aydin Yildiz , Akar Funda
Published: December 2021

Among the many applications in the field of computer vision, face recognition systems; is a subject that has been studied extensively and has been working for a long time. In general, the success of facial recognition systems, which consist of feature extraction and classifier steps, depends not only on the classifier but also on the features used. In a face recognition system, the feature selection is to obtain distinctive features for recognition of different facial images of interest. For this purpose, SIFT, SURF and SIFT + SURF features, which are unchanging features to scaling and affine transformations, are used in this study. In addition, to be able to compare with these local features, the HOG feature which is a global feature, also has been added to the study. Classification was performed using support vector machine. Experimental results show that local features are more successful than the global feature HOG.

What are academic journals good for? An editorial outlook on the possibilities of contemporary political research
Authors: GHICA Luciana Alexandra
Published: December 2021

The appointment of a new editorial team for an academic journal is an occasion for reflecting not only about the goals of a specific publication, but also about the relevance and intricacies of editorial work within the contemporary scientific landscape. Additionally, the process provided food for thought on the openings and limits of a disciplinary tradition - in this case, political science - within an institution, a country, a region and the larger academic community.

"Risk literacy" and social cleavages: Vulnerability in three acts
Authors:   ISM University of Management and Economics, Vilnius, Lithuania, HASHIMOTO Tom , ZIRGULIS Aras ,   ISM University of Management and Economics, Vilnius, Lithuania
Published: December 2021

Although recent studies show widening socio-economic divisions due to the COVID-19 pandemic, many such divisions were already identified as social cleavages. Scholars and observers tend to view the world in a dichotomous manner, overgeneralising their analyses along known cleavages. Therefore, the relevance of our work as scholars is at risk and we, the scholars of the contemporary world, are “vulnerable” to the temptation of ignoring the details, nuances, and complexities. The uneven impact of and recovery from the pandemic is not necessarily binary – for example, a refusal to follow the medical consensus (e.g. social distancing, vaccination) can be observed on both sides of many cleavages. Against such a background, this paper first characterises the pandemic as a medical, socio-economic, and information crisis. With the former two “pillars” resembling the known cleavages, the third pillar goes beyond the physical access to information and deals with the people’s perception of various risks. Such a behavioural angle to the vulnerability – labelled “risk literacy” – highlights the phenomenon of “digital divide” and shows a promising feature as an additional analytical tool. By familiarising ourselves with the people’s varying risk perceptions, we increase our own literacy against the risk of overgeneralisation. Keywords: risk literacy, social cleavages, information crisis, digital divide, risk perception, vulnerability, behavioural analysis, COVID-19, pandemic
The Romanian National Television and the Romanian Communist Party during the 1970s: A complicated relationship
Authors:   School of Doctoral Studies in History, University of Bucharest, Romania, BAUMGARTEN Silvia Cristina
Published: December 2021

To legitimize its actions and to control the population, the Romanian Communist Party (PCR) worked constantly to impose its vision, with the propaganda apparatus acting intensely during both the period of Gheorghe Gheorghiu-Dej, as well as during the reign of his successor, Nicolae Ceaușescu. From its establishment in 1956, the Romanian National Television (TVR) had been one of the instruments through which the voice of the communist authorities had been heard, both literally and figuratively. In this study I investigate the evolution of TVR as a propaganda tool of the communist regime during the 1970s, with a focus on the evolution of the propaganda programmes and on the main requirements of the Party. For this purpose, I used sources from the Romanian National Archives and the Archives of the Romanian Broadcasting Society, and I analysed the measures that PCR took in relation to TVR so that the latter meets the ideological expectations of the communist regime. Keywords: Romania, communism, Romanian Communist Party (PCR), Romanian National Television (TVR), propaganda, ideology, media studies
