An empirical comparison of stock market bubbles
Authors: Korkmaz Özge , Bari Bilgin , Adalı Zafer 
Published: December 2021

Financial asset bubbles occur due to systematic and continuous differences between fundamental and market values. Due to high growth periods and foreign capital inflows, bubbles are also seen in stock market indexes, especially in emerging market economies. This study analyzes the existence of bubbles in BIST100, IDX COMPOSITE, BOVESPA, MDEX, NIFTY 50, SHANGAI, and S&P 500 stock markets for the period 2009:01-2021:06. RADF, SADF, and GSADF tests are applied to detect bubbles on stock market closing prices. In addition, the emergence and demise dates of the bubbles are determined by employing the date-stamping method. The GSADF test gives more effective results and determines bubbles with different durations in all stock markets, except the S&P 500. The results reveal that the most inefficient market is IDX COMPOSITE, and S&P 500is the most efficient market. The analysis includes the S&P 500, the world's most liquid and most prominent stock market, for comparison. In this respect, bubbles occur more in emerging market exchanges. The findings also confirm the validity of the rational bubble law.

Organización partidista y rendimiento electoral. Una aproximación al caso de la derecha radical en España
Authors: Ortiz Barquero Pablo , Benítez Espinosa Andrés , Aragón Morales Alba María 
Published: December 2021

En las últimas décadas, el creciente protagonismo de la familia de partidos de derecha radical en Europa ha recabado una considerable atención académica, siendo uno de los principales objetivos el estudiar su rendimiento electoral. En este sentido, la literatura ha otorgado un papel preeminente a los factores de la demanda; de forma paralela, los factores de la oferta -que son aquellos que hacen referencia a las características de los propios partidos- han recibido mucha menos atención. No obstante, existen motivos para pensar que, dadas las limitaciones de las explicaciones centradas en la demanda, la agenda de investigación sobre la derecha radical necesita de una suerte de “giro internalista”. O lo que es lo mismo: una mirada más rigurosa y sistematizada sobre los factores de la oferta (y en especial, sobre aquellos relacionados con la organización partidista).
El objetivo de esta investigación es examinar el impacto de la dimensión organizativa en el rendimiento electoral de VOX en las elecciones generales de noviembre de 2019. En particular, se testa el impacto de dos factores organizativos -estatus socioeconómico de los candidatos e implantación territorial-, a través de análisis multivariante. Los resultados señalan la importancia de la esfera organizativa en el rendimiento electoral de la derecha radical en España y apuntan en la dirección de seguir profundizando en el estudio de los factores de la oferta política.

Revaluando el sionismo y la causa palestina: Intelectuales argentinos frente al conflicto árabe-israelí. Recepción y debates durante la Guerra de los Seis Días (1967)
Authors: Kahan Emmanuel Nicolás 
Published: December 2021

Una de las representaciones comúnmente sostenidas en torno a la década del sesenta del pasado siglo es la que consagra la figura del intelectual como uno de sus actores destacados. Las trayectorias, programas y posiciones de aquellas personalidades que animaron el debate público contemplando un escenario con diversas alternativas que propiciaban la “liberación” –ya sea internacional, nacional o individual– constituyó uno de los rasgos característicos del período. En el plano nacional, los estudios consagraron una figura del intelectual que se posicionó en torno a una agenda específica centrada en la redefinición del vínculo entre las izquierdas y el peronismo y la adopción de la lucha armada como una de las alternativas para la instauración de una sociedad más igualitaria al calor del impacto que tuviera la Revolución Cubana. Sin embargo, muchos de los intelectuales que participaron en esos debates –como tantos otros que no lo hicieron o, al menos, que no tuvieron reconocimiento público o académico posterior– también se posicionaron en torno a un universo más amplio de temas que, en aquel contexto, resultaron significativos. Por ejemplo, el conflicto árabe-israelí y las tensiones suscitadas en torno a la cuestión judía, la causa palestina y el sionismo. Este trabajo propone hacer un relevamiento de aquellas intervenciones intentado sopesar de qué modo los debates en torno a un conflicto extra-territorial constituyeron una plataforma en la cual vehiculizar posiciones en torno a la agenda política e intelectual de carácter nacional.

Published: December 2021

The polluting effect of wood sawdust left in nature acts especially on the environment due to biodegradation in time, under the action of bad weather, fungi and micro-organisms.
Forestry and agricultural waste can be transformed through a technological process in pellets, agricultural pellets or combustible briquettes, products which may be used for energetic purposes, leading to higher use of them, and to nature protection of natural pollution with these secondary products.
Determination of the influences of uncontrolled timber waste storage on the environmental components regarding the soil's quality in a site located in an unarranged sawdust warehouse area led to marking out an insignificant level of pollution induced by the quality indicator of phenols in all the soil profiles analyzed. Concentrations of pollutants in the air (ammonia and hydrogen sulfide) were below the limit value laid down in STAS 12574-87, while the measured concentrations of powders (PM 10) were located in the area of limit values.

Published: December 2021

Maize grain has many and diverse uses in the food and feed industry. The diversity of applications requires characteristics of quality in accordance to that. To examine phenotypical diversity in the grain content, it was evaluated a total of 754 maize samples: 265 local populations (landraces); 59 synthetics/composites; 430 “TURDA” inbred lines for their grain quality attributes. Comparison of the inbred lines diversity is on average the most divergent in grain starch concentration (range value 19.9) from landraces (range value 11.8) and synthetics (range value 12.5). The grain oil and ash content showed high variability among the genotypes. The quality attributes in most of the cases showed positive phenotypic correlation except grain starch contents which was negatively correlated at phenotypic levels.
The objective of this study was to evaluate the potential of maize “TURDA” germplasm in according to its grain quality content, such as: protein, oil, fiber, ash and starch concentration; to estimate the extent of phenotypical variability and correlation for various quality components to formulate a selection criterion in a breeding program.

Published: December 2021

Acrylamide is a colorless (or white), odorless, highly water soluble vinyl monomer formed from the hydration of acrylonitrile.
The chemical compound acrylamide is an amide with chemical formula C3H5NO and structure.
Acrylamide is a white odorless crystalline, soluble in water, ethanol and ether. It is used in papermaking, ore processing, manufacture of permanent-press fabrics, and the manufacture of dyes. Acrylamide is also used to synthesize polyacrylamides which find many uses as water-soluble stabilizers, for instance in waste water treatment and in gel electrophoresis (SDS-PAGE).
Acrylamide is also a probable carcinogen found in small quantities in some foods. It is believed to be created in foods when starches and other carbohydrates are overheated (far past 100°C) during cooking. Some sources claim that people in the modern world consume daily on average around 25 micrograms of acrylamide, and that this accounts for a significant number of cases of cancer.

The paper based on the researches carried out during 2005 – 2008 in the long term trial placed in 1990 on the preluvosoil from Oradea. The monoculture of maize, maize – wheat and maize – soybean – wheat crop rotations were studied in unirrigated and irrigated conditions. The crop rotatin of six years (oat + clover – clover – maize – wheat – maize - sunflower) was studied in unirrigated conditions. The researches emphasized that the monoculture is the most responsible for the pest multiplication.
In maize monoculture the larvae number on the roots was ranged between 4.91-8.23 and root attack degree in IOWA scale (with marks from 1 to 6 in which maximum attack is 6), had values between 3.84 and 5.62 and the frequent of attacked plants with the symptom “goose neck” ranged between 16,4% and 31.2% and larval aggressiveness being higher in the case of favorable soil moisture in irrigated condition. The maize rotation with other plants interrupts the biologic pest cycle.
The results obtained emphasize that later maize sowing alongside by the utilizing of lower plant thickness level contribute to prevention of pest multiplication, while earlier sowing at high thickness favor the larvae developing.

Published: December 2021

An important criterion for evaluating the technical condition of the spraying machines is to determine the uniformity of transverse distribution. Within this paper one has tried to establish the influence of pressure and height of application upon the transverse distribution uniformity. The machine on which the tests were conducted is the EEP 600 ME, designed at the Department of Agricultural Engineering and complies with the European Regulations.
The coefficient of variation was calculated and the maximum allowed limit was 9%.
During the experimental tests, the limit of acceptable distribution of 9% was not reached at any pressure (2,5 and 4 bar), nor height of application (50, 70 and 90 cm). For IDK 120-04 nozzles, at 2,5 bar pressure, the covered surface is not uniform, the trend line being on a descendent slope. Raising the pressure at 4 bar the uniformity of distribution is following an ascendant line. For 2,5 bar the coefficient of determination was 0.694, and for 4 bars 0.968.
For AD 120-02 nozzles, at 2,5 bar, the coefficient of determination was 0.327, and for 4 bars 0.949

Published: December 2021

Oxidative stress causes biological changes responsible for carcinogenesis and aging in human cells. The retinal pigmented epithelium is continuously exposed to oxidative stress. Therefore reactive oxygen species (ROS) and products of lipid peroxidation accumulate in RPE. Neutralization of ROS occurs in retina by the action of antioxidant defence systems. In the present study, the protective effect of caffeic acid (3,4-dihydroxy cinnamic acid), a dietary phenolic compound, has been examined in normal and in oxidative stress conditions (500 µM peroxide oxygen) in cultures human epithelial pigment retinal cells (Nowak, M. et al.). The cell viability, the antioxidant enzymes activity (CAT, GPx, SOD) and the level of intracellular reactive oxygen species (ROS) were determined.
Exposure to l00 µM caffeic acid for 24 h induced cellular changes indicating the protective effect of caffeic acid in RPE cells. Caffeic acid did not show any cytotoxic effect at concentrations lower than 200 μM in culture medium. Treatment of RPE cells with caffeic acid causes an increase of catalase, glutathione peroxidase and superoxide dismutase activity, especially in cells treated with hydrogen peroxide. Caffeic acid causes a decrease of ROS level in cells treated with hydrogen peroxide. This study proved that caffeic acid or food that contain high levels of this phenolic acid may have beneficial effects in prevention of retinal diseases associated with oxidative stress by improving antioxidant defence systems.
