Authors: Flores García Andrés , Moctezuma-López Georgel
Published: July 2021

Para México, en las últimas décadas los bosques naturales de coníferas han proveído de beneficios económicos. No obstante, en ellos se demanda su administración con el menor impacto posible. La regionalización basada en las Zonas de Movimiento de Germoplasma (ZMG) es una alternativa para la gestión de las masas arbóreas, que no limita los esfuerzos económicos y técnicos de las áreas operativas locales, estatales o de unidades de manejo forestal; sin embargo, son pocos los trabajos desarrollados con esta visión. Para determinar la cosecha de madera de las principales coníferas del país en las ZMG, se analizaron datos estatales sobre volumen de madera producida para especies de Pinus y Abies de 2013 a 2017. Se determinó que 19 taxones de pino y uno de oyamel son los que más contribuyeron a la producción forestal nacional. En particular, P. patula, P. douglasiana, P. maximinoi, P. pseudostrobus, P. teocote, P. oocarpa, P. montezumae y P. devoniana proveyeron 81.39 % del volumen total de los pinos; y con respecto al otro género, A. religiosa suministró 100 % del volumen total. Asimismo, las zonas X.3, V.3, XII.5, XII.3, X.1, XII.2, III.1, III.2 registraron 84.14 % de la cosecha de madera de pino, y X.3 acumuló 72.16 % de la correspondiente al oyamel.

Published: July 2021

Las elevadas concentraciones de plomo (Pb) en el suelo limitan el establecimiento de las plantas, por lo que es importante identificar especies tolerantes. El objetivo del presente estudio consistió en determinar el efecto de PbCl2 y Pb(NO3)2 en la germinación y crecimiento temprano de Parkinsonia aculeata. En laboratorio se imbibieron las semillas en soluciones de PbCl2 y Pb(NO3)2 a concentraciones de 0.0, 0.1, 0.2, 0.5, 1.0 y 2.0 mM. Las semillas se pesaron al inicio y al final (48 h); posteriormente, se incubaron y regaron con sus respectivas soluciones (7 días). En invernadero, las semillas se sembraron en arena y se regaron (15 días) para determinar el porcentaje de germinación (laboratorio) y emergencia (invernadero); las variables consideradas fueron: longitud de vástago, radícula y peso seco (ambas condiciones). Bajo condiciones controladas, PbCl2 y Pb(NO3)2 no afectaron la imbibición, pero al aumentar sus concentraciones, redujeron significativamente la germinación en 18 y 26 %, respectivamente, así como el peso seco del vástago (40 y 49 %), y radícula (40 y 57 %). En invernadero, los compuestos de Pb no redujeron la emergencia, pero inhibieron el crecimiento de radícula; mientras que el Pb(NO3)2 inhibió en mayor proporción su peso seco. El efecto del Pb puede diferir en función del compuesto de Pb utilizado. El Pb(NO3)2 presenta una mayor toxicidad.

Aktivitas berbahasa dalam dialog antara Bu Tejo dan Yu Ning juga menghasilkan dua model kognitif ideal tokoh Dian. Dari hasil transkripsi percakapan ditemukan pula dua model kognitif ideal menurut Bu Tejo dan Yu Ning. Perbedaan ini terjadi karena keduanya memiliki pengalaman sosial yang berbeda dalam berinteraksi dengan tokoh Dian. 
Abstract: The process of conceptualizing ideas is not only in the mind but also in human speech. Two problems that will be examined in this research are the frame and ideal cognitive model of Dian's character based on the dialogue of Bu Tejo and Yu Ning. The purpose of this research is to describe the frame in the dialogue between Bu Tejo and Yu Ning and to identify the ideal cognitive model of Dian in Tilik film. The data used in this research is the transcription of the Indonesian dialogue between Bu Tejo and Yu Ning. Data analysis used frame theory and ideal cognitive models within the scope of cognitive linguistics. Presentation of the results of the data alignment will be presented in the form of an informal presentation with a flow chart. The formation of the frames comes from the background knowledge of each individual. In the dialogue between Bu Tejo and Yu Ning, there are seven forming frames as the frame of work, wealth, truth, pregnancy, campaign, comfort, and culture. Language activity in the dialogue between Bu Tejo and Yu Ning also produced two ideal cognitive models for Dian. The transcription results of the conversation also found two ideal cognitive models according to Bu Tejo and Yu Ning. This difference occurs because both of them have different social experiences in interacting with Dian.

The present study aimed at development of finger millet-based functional beverage mix with 9% green banana flour and 1% ginger powder. The developed beverage mix was packed by using four different packaging materials i.e., low-density polyethylene (P1), standup pouch (P2), aluminium foil pouch (P3) and polyethylene terephthalate bottles (P4) and stored at room temperature. The changes in the physico-chemical, microbial quality were analyzed for 3 months (90 days). The results revealed that during storage, the moisture content was increased from 6.23 to 6.99%, whereas other chemical properties viz., carbohydrate (CHO), protein, fat, ash and dietary fiber were gradually decreased from 68.62 to 68.48, 15.09 to 14.99, 1.50 to 1.48, 3.74 to 3.73 and 2.78 to 2.77 respectively. There was no signifance change in calcium and phosphorus among the packaging materials during storage. The microbial load was low in P3 and P4 packed beverage mix during storage. The functional beverage mix packed in polyethylene terephthalate bottles was undergone minimum changes in physico-chemical characteristics. Hence, it is concluded that the storage of functional beverage mix in polyethylene terephthalate bottles extended the shelf life of the product and reduced the nutrient losses during storage.

Leaf blight caused by Alternaria alternata (Fr.) Keissler is a severe disease of Gloriosa, causing severe yield loss in every part of Gloriosa growing areas of Tamil Nadu. The foliar pathogen was isolated from disease-infected leaves and proved its pathogenicity. Further, the molecular analysis of the pathogen using 18S rDNA confirmed the pathogen as Alternaria alternata. Attempts were made to explore the biocontrol agents and fungicides for the management of leaf blight incidence under field conditions. Four field trials conducted from 2014 to 2018 revealed that foliar application of talc-based formulation of Bacillus subtilis significantly reduced the leaf blight incidence and increased the seed yield under field conditions. Besides, prophylactic application of these biocontrol agents has also increased the plant growth parameters like plant height, number of flowers/plant, no. of pods/plant and number of seeds/pod. Similarly, foliar application of chlorothalonil (0.1%) and mancozeb (0.2%) was also credited to managing the leaf blight disease under field conditions.

The present study aimed to evaluate the influence of bioregulators on physiological attributes and yield components of TNAU Papaya CO. 8 variety during 2017 - 2018. The study involved two factors viz., growth retardants as factor I and stress tolerance promoting bioregulators as factor II. The treatments involving growth retardants (Factor I) were water spray (G1) as control, 250 ppm of pro hexadione calcium (G2), 500 ppm of mepiquat chloride (G3) and 500 ppm of chlormequat chloride (G4). Similarly, the stress tolerance promoting bioregulators (Factor II) comprised of water spray as control (S1), 100 ppm of methyl jasmonate (S2), 100 ppm of salicylic acid (S3) and 0.6 g/ L of strobilurins (S4). The bioregulators were applied as foliar spray at the fourth and eighth months after transplanting. Initially, growth retardants were sprayed and one week after that, the stress tolerance promoting bioregulators were sprayed. Observations were recorded on number of leaves, leaf area index, leaf gas exchange parameters, papaya ring spot virusdisease incidence and yield components. Among the treatments, higher number of leaves (52.03) were observed in the combination involving 250 ppm of prohexadione calcium and 100 ppm of salicylic acid (G2S3) and leaf area index (2.73) was highly influenced by 500 ppm of chlormequat chloride and 100 ppm of salicylic acid (G4S3). Leaf gas exchange parameters were found to be superior with 250 ppm of prohexadione calcium and 100 ppm of salicylic acid treatment (net photosynthetic rate - 16.46 µmol cm-2 s-1, stomatal conductance - 0.51 mol m-2s-1, transpiration rate - 7.58 mmol m-2s-1) as compared to control. Significant differences were also observed among the treatments for yield and yield components. The fruit yield was significantly improved by the treatment involving 500 ppm of mepiquat chloride and 100 ppm of salicylic acid (G3S3 - 61.76 kg plant-1), indicating the possibility for enhancing papaya yield under field conditions where PRSV is prevalent.

Published: July 2021

Abstract. The inversion process of 1,3-cyclohexanedione was studied to know the energy associated with the chair-chair interconversion. 1,3-cyclohexanedione has a conformational inversion energy of 1.87 kcal/mol evaluated at M06-2x/6-311++G(2d,2p) level of theory. The global process combines inversion and topomerization originated by boat-boat interconversion that includes only two trajectories to the inversion transition state but no six-like cyclohexane, or four-like oxane and thiane. The process includes two different twisted boats associated with a boat transition state. A global scheme is proposed to represent this conformational equilibrium.

Published: July 2021

The use of local bean as an alternative food to meet the community's nutritional needs has been widely practised by society. One of the popular local beans in Kisar Island, Southwestern Maluku community, is gude bean. The people of Kisar Island have used gude beans and sweet potatoes to make traditional food, namely kolak (sweet compote), while the young pods are used as fresh vegetables. Gude bean can be used as a functional food such as gude essence, sweetened condensed milk, and soy sauce. The research objective was to determine the organoleptic assessment of food products from gude beans. Three sterile food products using gude beans were made in this research. The organoleptic tests were conducted on the Kisar community. Organoleptic panellists were fifteen (15) people originally from Kisar Island who live in Ambon city. Panellists were selected using a purposive sampling technique because they originally from Kisar Island know the nature of gude beans, like gude beans, have consumed gude beans. Descriptive analysis techniques were used as data analysis. The results showed that gude essence, milk, and soy sauce products had good taste, colour, texture, and aroma and were acceptable for consumption. This organoleptic test showed that the Kisar community could accept the gude bean food products.

Published: July 2021

An alternative methodology was developed to monitor the biokerosene content of palm kernel in blend with kerosene using medium infrared spectroscopy associated with partial least squares (PLS). The efficiency of this methodology was analyzed based on the parameters of accuracy and figures of merit. The values of root-mean-square error of cross-validation (RMSECV), root-mean-square error of calibration (RMSEC) and root-mean-square error of prediction (RMSEP) were in agreement because the RMSEP was higher than RMSECV and RMSEC. In addition, the RMSEP value is considered acceptable according to the Brazilian standard ABNT NBR 15568 because it is less than 1%. The figures of merit were performed in agreement with the requirements established in the standard ASTM E1655-05. The linearity of the model was assessed based on the analysis of the model fit through the correlation of the actual and predicted values of the calibration and prediction sets, where a high correlation between the values was evidenced, with a correlation coefficient (R) exceeding 0.99. The good results of the application of MIR spectroscopy combined with multivariate regression by PLS suggest that this analytical methodology is feasible, efficient and suitable for use by inspection agencies to control the biokerosene content of palm kernel in mixture with diesel.

En el avance por la igualdad de género atender a uno de sus frentes como es el lenguaje sexista continúa siendo un reto fundamental. Así, la educación y, en concreto, el profesorado se convierten en un factor fundamental para el cambio hacia un lenguaje no sexista (LNS). Este trabajo pretende analizar la actitud que tienen los futuros docentes durante su formación inicial hacia el LNS así como el uso de procedimientos lingüísticos inclusivos. La metodología utilizada se basa en la lingüística del corpus y el análisis de contenidos. Se han analizado 262 textos argumentativos de estudiantes de los grados de Educación Infantil y Primaria de diferentes universidades, y para el análisis de los datos se han empleado herramientas cualitativas y cuantitativas. Los resultados muestran que el masculino genérico es ampliamente usado entre quienes muestran una actitud de rechazo al LNS; no obstante, entre quienes manifiestan una actitud favorable al LNS, los índices de uso del masculino genérico superaban nítidamente a los procedimientos inclusivos. Estos datos indican que, en el contexto de la formación inicial del profesorado, las diferentes políticas de difusión y fomento del LNS conseguirían sensibilizar a más de la mitad de estos destinatarios.

Published: July 2021

Son numerosas las investigaciones que han destacado la importancia de la motivación en la adquisición de segundas lenguas. Tanto es así que se apunta a que la motivación, entendida esta como un componente dinámico, variable y determinado por factores internos, sociales y contextuales, puede contribuir al éxito o no en el proceso de aprendizaje de una lengua. Dentro de este marco de trabajo, este estudio busca conocer las actitudes de estudiantes bilingües (euskera y castellano) de los Grados de Educación Primaria y Educación Infantil hacia el inglés. 229 estudiantes de dichos grados han dado respuesta a un cuestionario acerca de los diferentes aspectos motivacionales que se circunscriben al aprendizaje de esta lengua. Los resultados atestiguan que son los factores externos y profesionales los que más determinan las actitudes positivas hacia el inglés. Asimismo, se observa que los estudiantes otorgan una importancia destacada a la labor del profesorado, a su gestión del aula y a su metodología. La relevancia de este estudio reside en la cada vez mayor importancia del inglés para los futuros docentes de estas etapas educativas en un modelo trilingüe que progresivamente va ganando peso a los modelos bilingües.

Fluoroquinolone-Induced Aortic Injury
Authors: Izmozherova N. V. , Popov Artem A. , Bakhtin V. M. , Markova E. V.
Published: July 2021

According to clinical studies, the use of ﬂuoroquinolone antibacterial agents is associated with such rare, but serious adverse reactions as aortic injuries. The aim of the study was to analyse scientiﬁc literature data on the risk of aortic injury during ﬂuoroquinolone treatment. The analytical review showed that the risk factors for ﬂuoroquinolone-induced aortic injury are male gender, age over 45 years, underlying aortic disease, as well as smoking and associated atherosclerosis. Clinical and morphological forms of ﬂuoroquinolone-associated aortic injuries include dilatation (aneurysm development), dissection, and rupture. The analysis of data on the association between aortic injuries and the use of most common ﬂuoroquinolones (ciproﬂoxacin, levoﬂoxacin, and moxiﬂoxacin) showed that development of aneurysm and dissection was most often observed for levoﬂoxacin, and least often for ciproﬂoxacin. The mechanism of aortic injury is due to ﬂuoroquinolone-mediated activation of matrix metalloproteinases which damage elastic components of vascular walls, as well as reduction in lysyl oxidase expression and collagen synthesis. The ability of ﬂuoroquinolones to form complexes with magnesium ions reduces the availability of magnesium to the cell enzyme systems, which delays synthesis of extracellular matrix structural proteins, leads to metalloproteinase activation and calciﬁcation of the vascular walls. Prevention, early detection, and timely management of the above-mentioned issues depend on the awareness of diﬀerent medical specialists about the risks of aortic injury associated with the use of ﬂuoroquinolone antibiotics.

Published: July 2021

Background. Tinomiscium petiolare Hook.f. & Thomson is a medicinal species of the family Menispermaceae. This species is currently being intensively exploited for therapeutic purposes. Precise and rapid identification of T. petiolare is critical and essential for the classification, propagation, use and conservation of its genetic resources. In recent years, DNA barcoding has been known to be a fast and sensitive method for identifying species at any stage of development, using short DNA sequences. In this study we have performed the identification of T. petiolare specimens in Vietnam based on the sequence analysis of 4 DNA barcode loci: ITS, matK, rbcL and rpoC.Materials and methods. Total DNA was extracted from leaf samples using DNeasy Plant Mini Kit. PCR amplification of the ITS, matK, rbcL and rpoC regions was carried out on the GeneAmp PCR System 9700 with specific primers. The purified PCR products were sequenced on the ABI 3500 Genetic Analyzer system, using BigDye®Terminator v3.1 Cycle Sequencing Kit. These genetic sequences were analyzed and compared, and a phylogenetic tree was constructed using BioEdit, BLAST, and MEGA 6 programs.Results and conclusion. The success rate of amplification and sequencing was 100% for all 4 DNA barcode loci (ITS, matK, rbcL and rpoC) in the studied specimens. The produced sequence sizes of ITS, matK, rbcL and rpoC in the specimens were 574 bp, 810 bp, 527 bp and 488 bp, respectively. Further, we identified that all studied specimens were genetically related to each other and associated with the same species T. petiolare. Overall, the results of the study generated the most complete DNA barcode database of T. petiolare collected in Vietnam, contributing to the taxonomy and identification of this species.
Morphological features of rye grain with low pentosan content
Authors: Kobylyansky V. D. , Solodukhina O. V. , Nikonorova I. M.
Published: July 2021

Background. The grain coat plays a major role in the development of rye cultivars with low levels of water-soluble pentosans (WSP). Grain coat thinness is a diagnostic trait for low WSP (arabinoxylans) content. To improve the technology of low-pentosan rye breeding, it becomes important to study the effect of changes in the anatomy of low-pentosan grains on morphological characteristics.Materials and methods. Grains with thin coats (transparent) were identified with the LFS-1 diaphanoscope in the populations of 7 commercial winter rye cultivars grown in Russian Federation. Anatomical and morphological features of seed coats were studied on thick- and thin-coated grains identified in the rye cultivars ‘Era’ and ‘Vyatka’. The thickness of grain coats and the aleurone layer were assessed according to L. N. Lyubarsky.Results and conclusions. In thin-coated rye grains, we found a reduction in the thickness of the pericarp and seed coats by 50–70% and in the aleurone layer by 32.1–39.6%, compared to thick-coated grains. With a constant cell size in “transparent” grains, a decrease in the thickness of the aleurone layer and coat occurs at the expense of the reduction in not only the cell walls, but also the intercellular space. The pericarp in the tissues of the second multicellular layer contains the bulk of the protective biologically passive WSP. It was proved that there were no significant changes in grain parameters, such as length, width and relative volume, depending on coat thinness. Significant differences were found in the 1000 grain weight. In “transparent” grains the index increased by 5.2–19.7%, compared with “nontransparent” ones.

Cultivars and promising materials developed at the Spring Durum Wheat Breeding Laboratory, Omsk Agrarian Scientific Center (OASC), lines obtained under the CIMMYT and KASIB programs, and accessions from the VIR collection were the objects of research. Field experiments, phenological observations, and assessment of stem rust resistance were carried out from 1990 through 2019 in the OASC experimental fields using conventional methods. Resistance to the Ug99 race was evaluated under natural infection pressure at the Kenya Agricultural and Livestock Research Organization (KALRO).Results. Promising source material was identified and included in the Laboratory’s breeding program. The ways were shown to develop stable cultivars of spring durum wheat for the environments of Western Siberia. A strategy was proposed for the selection of genotypes in hybrid combinations of spring durum wheat: it would include early selection (starting from F2 ) for disease resistance with simultaneous screening for quantitative traits and pasta-making qualities. The description and advantages of cv. ‘Omsky korall’, submitted to the State Variety Trials in 2018, are presented. This cultivar combines high yield, adaptability, resistance to the local population and the Ug99 race of the stem rust pathogen, and excellent pasta-making qualities.Conclusion. As a result of these studies under heavy stem rust pressure in Western Siberia, all breeding nurseries obtained source material resistant to the Omsk population of P. graminis. The released cultivars ‘Omskaya yantarnaya’ and ‘Omsky izumrud’ demonstrate resistance to the Omsk population of the stem rust causative agent.

Published: July 2021

Background. One of the global problems presently faced by humanity is obesity and overweight. For treatment and prevention of this disease, doctors recommend consuming more vegetables, cucumbers in particular. Despite the fact that Russia is one of the major cucumber producers, its average yield is more than twice lower than in the EU countries. To meet the demand of the population, it is necessary to additionally import the missing products. In this regard, the urgent need for an increase of cucumber production is obvious, and first of all, by raising the yield.Materials and methods. The research was conducted at the experimental sites of Volgograd Experiment Station of VIR. Accessions from VIR’s cucumber collection served as the material for the study. Methods developed and accepted by VIR were used in the research.Results and conclusions. Such agronomic characteristics as yield, fruit weight and length, thorn color, dry matter and sugar content were studied. A noticeable direct correlation was found between fruit length and fruit weight, and moderate direct correlations were observed between yield and fruit length, yield and fruit weight, dry matter and sugars. The indicators showing suitability of accessions for salting and canning were analyzed. Accessions that can be used in breeding practice are recommended. A conclusion is made about the prospects of breeding for valuable agronomic traits using long-fruited forms of cucumber from the countries of South-East Asia and the Russian Far East.

The immune North American grapevine species Vitis rotundifolia Michaux (subgen. Muscadinia Planch.) is regarded as a potential donor of disease resistance genes, withstanding such dangerous diseases of grapes as powdery and downy mildews. The cultivar ‘Dixie’ is the only representative of this species preserved ex situ in Russia: it is maintained by the N.I. Vavilov All-Russian Institute of Plant Genetic Resources (VIR) in the orchards of its branch, Krymsk Experiment Breeding Station. Third-generation sequencing on the MinION platform was performed to obtain information on the primary structure of the cultivar’s genomic DNA, employing also the results of Illumina sequencing available in databases. A detailed description of the technique with modifications at various stages is presented, as it was used for grapevine genome sequencing and whole-genome sequence assembly. The modified technique included the main stages of the original protocol recommended by the MinION producer: 1) DNA extraction; 2) preparation of libraries for sequencing; 3) MinION sequencing and bioinformatic data processing; 4) de novo whole-genome sequence assembly using only MinION data or hybrid assembly (MinION+Illumina data); and 5) functional annotation of the whole-genome assembly. Stage 4 included not only de novo sequencing, but also the analysis of the available bioinformatic data, thus minimizing errors and increasing precision during the assembly of the studied genome. The DNA isolated from the leaves of cv. ‘Dixie’ was sequenced using two MinION flow cells (R9.4.1).

Background. Development of early-ripening spring bread wheat (Triticum aestivum L.) cultivars is an important task for Russian breeders. Knowledge of the genetics of ultraearly varieties – sources of valuable genes that determine an earlier-maturing type of plant development –will be used to work out methods for obtaining source material for breeding.Materials and methods. The ultra-early lines Rico (k65588, var. erythrospermum Koern.) and Rimax (k-67257, var. lutescens (Alef.) Mansf.), and cvs. ‘Max’ (k-57181, var. lutescens) and ‘Leningradskaya 6’ (k-64900, var. lutescens) were studied. Alleles of the Vrn and Ppd genes were identified by PCR according to known publications, and genomic DNA was isolated from 3-day-old seedlings by the CTAB method.Results. In the environments of Northwest Russia, the Rimax and Rico lines are characterized by the highest rate of development before heading among the spring wheat accessions from the VIR collection. In the Rimax and Rico genotypes, the Vrn-A1, Vrn-B1, Vrn-D1 and Ppd-D1 genes were found. Genotypes with different alleles of Ppd-D1 and Vrn-B1 were identified in the Rimax line. Under conditions of a long day (18 hours), in the population of F2  (F3 ) Rico × Rimax hybrids, the ratio of phenotypes with a high development rate to all others was observed as 1 : 15 (χ2 1: 15 = 0.64). Under a short day (12 hours), 5 clearly tested groups were identified in F2 with the ratio 1 : 4 : 6 : 4 : 1 (χ2  = 3.03; χ2 0.05 = 9.48), which indicates the manifestation of cumulative polymerization.Conclusion. Each of the Rimax and Rico lines has two pairs of independent duplicated genes that determine a high development rate. Under short-day conditions, these genes can interact like cumulative polymers. The Rimax and Rico lines, due to their high development rate, are valuable source material to be used in breeding for earliness.
Crop wild relatives of Karachay-Cherkessia: inventorying and conservation prospects
Authors: Bagmet L. V.
Published: July 2021

Studying wild relatives of cultivated plants in each specific region is an essential component in assessing the state of national plant genetic resources. This is especially true for the regions of the Russian Caucasus, with its tremendous diversity of plant species. This paper presents the results of exploring crop wild relatives (CWR) in natural plant communities of the Karachay-Cherkess Republic. The author conducted an inventory of CWR and analysis of their species composition in Karachay-Cherkessia. The CWR list includes 516 species belonging to 134 genera of 36 families; in this list, 449 species from 107 genera of 33 families are native to this region. The Dzheguta floristic district is the richest in CWR species diversity (391 species). There are 350 and 346 species in the Arkhyz and Uchkulan districts, respectively, and 301 species in the Cherkessk district. Species were ranked according to their agricultural value and economic importance: the 1st rank was assigned to 149 plant species, 2nd rank to 17, 3rd rank to 32, 4th rank to 97, and 5th rank to 222 species. In the context of their economic use, the species for feed (158) and food (136) purposes dominated over those for medicinal (60), melliferous (54), ornamental (53), industrial (51), and revegetation (5) applications. The list of priority conservation species was compiled for CWR of Karachay-Cherkessia according to the criteria of rarity and vulnerability, based on the analysis of the CWR species distribution over the studied area and their assessment for useful economic and biological traits. A map showing localities of these species within the Republic is presented, and recommendations are given for their effective conservation.
El saber psi y el campo de la salud: la circulación del discurso psicoanalítico en revistas especializadas (1946-1955)
Authors: Savio Karina
Published: July 2021

En este artículo analizamos los distintos modos que el discurso psicoanalítico adopta en el entramadosocial argentino durante los años en los que el peronismo detenta el poder, es decir, entre 1946-1955. Para ello, se ha tomado en cuenta la relación que se establece entre este saber, en aquel entonces, novedoso, y el campo de la salud. A su vez, se ha relevado el lugar que ocupa la dimensión social en este ámbito y su articulación con el psicoanálisis. Con este objetivo, se han revisado publicaciones de diversas revistas especializadas vinculadas con la psiquiatría, la pediatría, la higiene mental, la kinesiología y la medicina del trabajo. Como herramienta conceptual, hemos partido de la noción objeto discursivo empleada por el análisis del discurso. Nos ha interesado examinar los sentidos que se constituyen en torno al objeto psicoanálisis endichos materiales. A pesar de que el vínculo entre este saber y el peronismo ha sido, por lo general, relegado en las investigaciones que buscan rastrear las huellas de su devenir en este país, en este trabajo se ha evidenciado que el objeto-saber psicoanálisis adquiere en estos años tres sentidos diferentes: como saber cuestionable, como saber teórico y como saber revolucionario. Asimismo, se ha comprobado la importancia de la dimensión social en algunos de los artículos estudiados.
Rule of Law and Constitutionalism in Nigerian Democracy: A Critical Relativism Discuss in the Context of International Law
Authors: Igwe Isaac O. C.
Published: July 2021

The synthesis of rule of law enthrones democracy, justice and goes with such characteristics as liberty, freedom, and the restoration of the dignity of man. The rule of law is predicated upon absolute autonomy being accorded to the judicial arms of the government of any society, state, or country. Thus, the application and interpretation of the law must be under the control of impartial courts adjudicating within the ambit of fair judicial procedures. The dialectics of power and the guiding principles of governance are anchored in the constitution which enshrines the provisions of enforceable laws. The law is the cardinal power of a nation, a direction for due process, and a guiding principle for good governance. The age of enlightenment and the middle ages have a special place for the rule of law as opposed to tyranny otherwise, life could have been chaos. The role of law cannot be left in isolation of democracy as both are interlaced as core universal principles of the civilised world. This paper will explore the rule of law as a paramount factor in constitutionalism, idealism, and realistic principles of the law of any given society. The treatise will in general terms discuss the principles of rule of law and articulate it with the hitherto Nigerian democracy. It will conclude with the argument that complete independence of the judiciary in Nigeria is paramount to ensure proper implementation of rule of law for a better Nigeria.
