Authors: Kiruba J.
Published: December 2020

Leadership is an important aspect of managing people. It is the art of dealing with and influencing people so that they will try hard happily and actively toward the achievement of group or organizational goals. The leaders understand what makes their followers to get motivated and how well these motivations operate. This understanding will reflect in their leadership behaviour. Preparing young people for leadership responsibility begins at home with an enriched environment that offers opportunities for children to acquire broad interests, self-esteem and the insights and skills that characterize leaders. Parents can provide their children with support and encouragement as they participate in a wide variety of home and community activities. The aim of the present study is to find out the level of leadership behaviour of B.Ed. trainees. The investigator has used the leadership behavior inventory as tool. The sample consists of 300 B.Ed. trainees from six B.Ed. Colleges in Kanyakumari District. Stratified random sampling technique has been used for collecting the data. The major finding reveals that there is significant difference between rural and urban B.Ed trainees in their leadership behaviour.
THE SOCIO ECONOMIC FACTORS AFFECTING GIRLS’ ACADEMIC ACHIEVEMENT AND GENDER BASED VIOLENCE IN HIGHER INSTITUTION: CASE STUDY IN UNIVERSITIES IN AMHARA REGIONAL STATE
Authors: Gebeyehu Zelalem , Kathiresan A.
Published: December 2020

At the beginning of human history, the environment favored and promoted equality of males and females. However, as the exposure of males to the natural environment differed, various activities and dangers increased, both sexes started to differ in the nature and depth of experience. Since then, the gender disparity that began in this way was widened by religious, political, economic, cultural and other factors. Currently, gender differentiations are reflected in the accesses to the three precious things of the world, political power, economic privileges and social or cultural prestige. In the 21st century, knowledge plays the leading role and education is the central element that nations can use to maintain equality among society specially to insure gender equality. Thus this paper would attempt to identify the socio-economic factors affecting girl's academic achievement and gender based violence in higher institutions in case of Amhara regional state by selecting two university from first, one from second and two from third generation universities including Wollo five universities will be included out of the total seven universities found in the region. The respondents are selected randomly from each university. The respondents included in this study are female students, gender office, instructors, student deans and registrar workers. The data would be collected using Focus group discussion, interview and questionnaires. To analyze the data logistic regression and two limit Tobit model would be used. Even if there is some progressive trend, the girl’s academic achievement is low and their attrition rate is high. That is their mean achievement below the national average.  From econometrics result it has been found that entrance exam result, parents income, personal related factors, peer pressure the major factors that substantially determines level of girl’s academic achievement. Similarly, though there are positive changes regarding gender based violence still significant portion of girls were vulnerable. That is 20 percent out of the total surveyed girls were violated and 22.59 percent still exploited by the transaction sex in the nearby cities. Besides, the logistic regression  analysis showed that gender based violence highly depend on the personality those girls with strong personality and self-esteemed girls have less chance of being harassed or abused verbally, physically and psychologically.

Authors: Subathra C.
Published: December 2020

Decision-making is one of the most important elements in the administration of any organization. In higher education, college is an institution, in which the principal is a prime person who makes decision. This article investigates the perception of college principal towards his decision Making style. Numerous studies in the area of Management and Leadership indicate that one’s decision making style (DMS) is reflective of one’s leadership style. Using the Decision Making Styles Inventory (DMSI) developed by Rowe and Boulgarides (1992), this paper attempts to explore and report the managerial DMS among 130 college principals in Kanyakumari District. The scores derived from Decision making inventory were categorized into four decision styles namely: Directive, Behavioral, Analytical and Conceptual. Results revealed that a majority of principals adopted a very dominant or dominant intensity level for Behavioral Decision Making Style.
SOCIAL ENTREPRENEURSHIP: CHALLENGES IN WAY TO RISE
Authors: Devi Seema
Published: December 2020

Social entrepreneurship is the use of the techniques by startup companies and other entrepreneurs to develop, fund and implement solutions to social, cultural, or environmental issues. This concept may be applied to a variety of organizations with different sizes, aims, and beliefs. For-profit entrepreneurs typically measure performance using business metrics like profit, revenues and increases in stock prices, but social entrepreneurs are either non-profits or blend for-profit goals with generating a positive "return to society" and therefore must use different metrics. Social entrepreneurship typically attempts to further broad social, cultural, and environmental goals often associated with the voluntary sector  in areas such as poverty alleviation, health care and community development. This article builds on the literature to define social entrepreneurship, discusses the boundaries of socially-oriented entrepreneurial activities, and positions the social entrepreneur in the spectrum of entrepreneurship.

Authors: Jain Sushma
Published: December 2020

The painting tradition in the Maratha region dates back to prehistoric times. Human beings have left examples of paintings with a very careful reflex of behavior. In the primitive tendons of Madhya Pradesh, we are surprised today by the many linear signs of the human and the aesthetic form of the weapons, following the craving to be cultured and ornate on that barbar.

मराठा क्षेत्र में चित्रकला परंपरा का प्रारंभ प्रागैतिहासिक काल से होता है। मानव ने बहुत ही प्रांरभ में व्यवहार की सजगता के साथ चित्रों के उदाहरण छोड़े हैं। मध्यप्रदेश की आदिम कंदराओं में हमें उस बर्बर पर सुसंस्कृत और सुअलंकृत होने की लालसा के अनुगामी मानव के रचे अनेक रेखीय चिन्ह तथा अस्त्र शस्त्रों के सौंदर्य प्रधान रूप आज हमंें आश्चर्य चकित करते है।1

CLONING AND EXPRESSION OF Lb-PROTEASE FROM cDNA CLONE OF FOOT-AND- MOUTH DISEASE VIRUS
Authors: Sarkar Swaroop , Suryanarayana V.V.S. , Shankar S.R.Madhan
Published: December 2020

Foot-and –Mouth disease virus (FMDV) is a positive sense RNA virus and the genome codes for single polyprotein. The FMDV L protein is located at the N terminus of the polyprotein and is the first gene product released from the nascent polyprotein. The leader L protease which is involved in pathogenesis has two known functions: (i) auto-catalytic removal from the N terminus of the viral polyprotein and (ii) cleavage of the p220 subunit of the eukaryotic initiation factor 4F complex, which helps to shut off host protein synthesis. To explore the role of L protease in FMDV pathogenesis we generated synthetic FMDV genome lacking the L gene. The gene was amplified from an infectious cDNA clone of serotype Asia1. Primers corresponding to L protease were designed based on the sequence available in the data base. An amplified DNA of 546bp was purified and cloned into pET28 cloning vector. The sequence analysis revealed the presence of single Open Reading Frame (ORF) encoding a protein of 173 amino acid residues. The sequence alignment using BLAST search in NCBI gene Bank showed 91% homology with FMDV strain A isolate IND17/77 L protease gene. The recombinant plasmids pETLb was transferred into BL21 (DE3) pLysS cells and the IPTG induced expressed protein of 25 KDa was purified by nickel affinity column as per the manufacturer’s protocol (Sigma, USA). The specificity of the expressed protein in was confirmed by western blotting using convalescent cattle serum/ rabbit anti-bovine horse radish peroxidase conjugate and O-Dianisidine Dihydrochloride substrate.

Authors: Harry S.T. , Adekanmbi M.A
Published: December 2020

A review of the ground state confinement energy term in the Brus equation for the bandgap energy of a spherically shaped semiconductor quantum dot was made within the framework of effective mass approximation. The Schrodinger wave equation for a spherical nanoparticle in an infinite spherical potential well was solved in spherical polar coordinate system. Physical reasons in contrast to mathematical expediency were considered and solution obtained. The result reveals that the shift in the confinement energy is less than that predicted by the Brus equation as was adopted in most literatures.

Published: December 2020

La actitud de los docentes frente a la inclusión es un factor clave si queremos avanzar hacia el desafí­o de contar con comunidades educativas cada vez más inclusivas. El objetivo de este estudio busca validar un cuestionario sobre la actitud docente frente a la inclusión educativa en Chile. Se efectúa un estudio descriptivo –survey, de corte transversal–transeccional, no experimental, con una muestra no probabilí­stica (accidental). Para ello se encuesta a 497 docentes que se desempeñan en escuelas municipales de Chile. Se utiliza un cuestionario con escala Lickert con 19 preguntas, para determinar la actitud frente a la inclusión. La medida de Kaiser-Meyer-Olkin KMO fue 0.893 y la prueba de esfericidad de Bartlet fue altamente significativa (X2= 4196.261, gl = 171, sig 0,000). Por otro lado, las cargas factoriales en las 19 preguntas oscilaron entre < 0.500 a 0.899 y la fiabilidad en general evidenció un Alpha de Cronbach (r=0.85). Se verifica, por tanto, que el cuestionario es válido y confiable en Chile para determinar la actitud docente frente a la inclusión educativa.

Authors: Karpova N. S. , Brusov O. S. , Oleichik I. V. , Faktor M. I. , Levchenko N. S. , Sizov S. V. , Nikolaeva E. R.
Published: December 2020

Background: currently, it has been proven that the pathogenesis of endogenous mental disorders is associated with the process of neuroinflammation in the brain of patients. It is also known that chronic neuroinflammation, accompanied by a violation the permeability of the blood-brain barrier. It is accompanied by the activation of platelets that generate procoagulant microparticles, which leads to a disturbance of the hemostasis system, causing an increase in blood clotting in patients. Objective: to investigate the dynamics of procoagulant activity of blood in patients with endogenous mental disorders before and after psychopharmacotherapy.

Patients and methods: the study included 185 patients aged 16 to 64 years with the following mental disorders: schizophrenia with attack-like/attack-progressive/continuous type of course (F20.00–2), affective disease (F31.1–5; F32.0–3; F33.0–3), schizotypal disorder with affective fluctuations (F21.3–4). The thrombodynamic test (TD) was performed on T-2 Trombodynamis device according to the manufacturer’s instructions (Hemacore LLC, Moscow, Russia). All patients received standard pharmacotherapy according to their condition.

Results: a significant decrease of procoagulant activity of spontaneous clots in the patients’ blood after psychopharmacological treatment is observed. Our data on the positive dynamics of changes in the values of TD test’s indicators in most of the examined patients suggest that a decrease in the coagulation activity of the patients’ blood as a result of treatment may be associated with the anti- inflammatory effect of antipsychotics and antidepressants.

Conclusion: for the first time, it was shown that there is a positive dynamic in changing the values of the main parameters of the TD test in most patients with endogenous mental diseases. The results of TD tests can be the basis for monitoring the response to therapy.

Published: December 2020

Objective: to construct a mathematical model that predicts the state of depression by immunological parameters in the blood plasma of older people to further predict the development of the disease.

Patients and methods: 55 hospitalized patients of late age (mean age 69.2 ± 6.9 years) with a depressive episode were included in the study. The control group consisted of 41 elderly people (average age 66.6 ± 6.2 years) without depressive disorders. The activity of inflammatory and autoimmune markers in the blood plasma of patients and control groups was determined: the enzymatic activity of leukocyte elastase (LE), the functional activity of the α1-proteinase inhibitor (α1-PI), the level of autoantibodies to neuro-specific antigens S100B and the myelin basic protein (MBP). Statistical data processing was performed using the R (R version 3.2.4) and STATA (version 12.1) programs. We used point-bead-correlation to measure the strength and direction of the relationship between the binary variable and continuous variables and logistic regression to predict the probability of occurrence of events of interest by the values of one or more independent variables (predictors).

Results: in patients with depressive disorders, a statistically significant increase in the functional activity of α1-PI (p ≤ 0.05) and the level of autoantibodies to the neurospecific S100B antigen (p ≤ 0.05) was revealed compared with the control. LE activity and MBP level did not differ from the control (p = 0.12 and p = 0.1, respectively). Based on immunological parameters in elderly patients with depression, a mathematical model is constructed. The accuracy of the correct prediction of outcomes using the model as a whole was 83.33%, which indicates a high predictive efficiency of this model.

Conclusion: the results of mathematical analysis obtained in this work indicate that immunological parameters such as the functional activity of α1-PI and S100B are statistically significantly associated with the likelihood of depression in the elderly. Indicators such as enzymatic activity of LE and the level of autoantibodies to MBP did not have a statistically significant effect on the desired probability.

Authors: Svetlichnaya T. G. , Voronov V. A. , Smirnova E. A.
Published: December 2020

Objective: the comorbidity of schizophrenia and tobacco and alcohol addiction modifies the clinical manifestations of both diseases, impairs compliance, increases the risk of aggressive behavior and contributes to the criminalization of patients. In order to study the characteristics of tobacco smoking and alcohol consumption by patients with schizophrenia, we conducted a medical and sociological study of the specified contingent.

Patients and methods: 104 in-patients with diagnosis of schizophrenia admitted to psychiatric hospital were interviewed in February 2020. All patients participating in the study have reached the age of 18. The research program is presented by the “Questionnaire for the study of smoking and alcoholic behavior in patients with mental disorders”. Evaluation of smoking status included K. Fagerström’s test, A. Leonov’s test “Why do I smoke?” To determine the motivation to smoke, smoking index was calculated to determine the risk of developing COPD, and the AUDIT test was used to assess alcohol consumption. Statistical processing of the results of the questionnaire survey was using the SPSS-17 software. The prevalence of smoking among patients with schizophrenia is high (56.8%). Most (86.4%) of them are heavy (66.1%) and hardcore (20.3%) smokers. A high degree of dependence was revealed, the smoking experience averages 27.6 years, and the number of cigarettes smoked per day ranges from 10–20 and even up to 60 pieces. The patients are characterized by early onset of smoking (15.2 years) and the prevalence of high (47.5%) and medium (18.6%) degrees of nicotine addiction. The prevalence of alcohol consumption among patients with schizophrenia is very high (36.5%). Most (73.7%) patients consume alcohol either regularly (31.6%) or habitually (42.1%). Every fifth (21.2%) stopped drinking alcohol due to poor health.

Conclusions: high prevalence of smoking and alcoholic addiction in patients with schizophrenia increases the medico–social significance of this comorbidity.

L’Apocalisse come eccezione nel canone neotestamentario
Authors: Antonioli Ermanno
Published: December 2020

The textual canon of the New Testament established by the Church is usually regarded as the model par excellence of a canon’s strict coherency and normativity. Nonetheless, what is explored here is that this archetypal model of a canon carries in itself an almost irresolvable problem of incoherency, constituted by the Book of Revelation. Thus, the aim of this contribution is firstly to show why this book represents a remarkable exception in the New Testament canon for its genre, content and tone (§§ 1, 2); and secondly to underline the reasons and the implications of its acceptance in the canon (§ 3).

Appunti sulla ricezione della xilografia nordica in Italia tra XV e XX secolo
Authors: Gigante Lorenzo
Published: December 2020

Germany, France, Italy: the attribution of the first woodcut images has long been debated between several countries, to gain the technological primacy of the invention of reproductive printmaking, before Gutenberg’s movable type printing. Today we know how difficult it is, if not impossible, to establish a place and a date of origin of image printing in Europe. Impossible and probably unimportant. Printing was a European phenomenon in the 15th century, and we may ask ourselves whether a northern woodcut beyond the Italian borders was intended as something different than an Italian one. The contrast between northern and southern prints, which has been claimed by art historians from Vasari until the half of the 20th century, seems to be denied by early modern Italian sources. For example, a German woodcut from the first decades of the 15th century and a Florentine painting from the end of the 14th century can coexist as models for the illumination of the same manuscript. This unpublished case study of two Florentine 15th-century illuminations shows how a European cultural horizon was more common than we think today, and how much woodcut has been a fundamental tool for this broadening of horizons, since its very beginning.
Итальянская живопись ‘до Рафаэля’ в творчестве Николая Рериха
Authors: Voytekunas Valentina
Published: December 2020

At the turn of the 20th century, interest in Italy and the artistic heritage of the Old Italian Masters, especially the Proto-Renaissance and Early Renaissance was a noticeable phenomenon in Russian culture. Painting ‘before Raphael’ became one of the most important sources that influenced the style and imagery of many Russian artists, including Nicholas Roerich. This article examines the factors that determined Roerich’s interest in early Italian art and analyzes the direct experience of the artist studying ancient painting in Italy, which was reflected in his artistic practice of the 1900s-1910s.
Timur Novikov. L’attualità del passato
Authors: Redaelli Maria
Published: December 2020

This contribution focuses on the activity of Timur Novikov (1958-2002) and his dynamic approach to Western or national patterns, to classicism or avant-gardism. His artistic activity stands as the perfect case study when discussing appropriations and negations in the development of an artistic canon. The focal point for interpreting Novikov’s dynamical activity is his trademark parodic approach to his work, through the use of the so-called stiob, and in the text this aspect will be analysed on the basis of Linda Hutcheon’s theory of parody ([1985] 2000). Examining Novikov’s career, taking and denying different aesthetic canons, is essential to understand the development of Russian contemporary art.

Wound dressing have experienced continuous improvement and changes since ancient time. Electrospinning of polymeric nanofibers have captured the interest of researchers due to its simplicity and cost effective technique that able to produce wound dressing membrane that meet the requirement as ideal wound dressing and drug delivery carrier. In this work, polyvinyl alcohol (PVA) and poly (lactic acid) (PLA) were chosen polymer to produce wound dressing membrane through electrospinning and coating method. PVA was electrospun and then coated with PLA. Preliminary study had been conducted between 1, 4 and 8% concentration for the selection of optimum PLA coating concentration. PLA has been proposed for the use of coating materials at 4%, the coated nanofiber membrane started to exhibit high Ultimate Tensile Strength at 1022.5 ± 9.28 MPa, highest degree of swelling (1850 ± 3.7 %) and optimum water contact angle (60.9 ± 11.46˚). The aim of this study was to investigate the morphological properties of PVA/PLA wound dressing membrane. Based on the results from Atomic Force Microscope, PVA nanofiber coated with 4% PLA exhibit the highest value of Rq which is 0.47 ± 0.19 μm compared to neat PVA nanofibers membrane. Field Emission Scanning Electron Microscope (FE-SEM) image revealed that PVA nanofiber coated with 4% PLA shows porous fiber-like morphology and well incorporated with each other without any gap formed between them. This report clearly suggestive of the fact that synthetic biodegradable polymers such as PLA can be exploited for the synergistic combination with PVA nanofiber for wound dressing application.

Published: December 2020

Objective: to describe the perception of the patient undergoing larval therapy. Method: qualitative, exploratory-descriptive study, using oral history as a data collection technique and methodological framework, in the form of oral life history. Six patients with difficult-to-heal wounds participated in the study, followed by the dressing committee of a teaching hospital in Natal, Rio Grande do Norte, undergoing larval therapy. Results: the testimonies of the patients/collaborators point to various values, such as belief, fear, acceptance, improvement of the wound and pain. They revealed that there is no major objection and that clarification regarding the treatment instituted proved to be important in the acceptance decision. Conclusion: the feelings expressed by the patients, such as improvement of the wound, reduction of pain and odor, optimization of the healing process, emergence of sparks of hope regarding the return to their life, among others, translate the benefits of Larval Therapy (LT). Despite the seizure caused by the animal’s movement over the affected area and the disgust it causes to some professionals and people, LT was considered wonderful, especially for its effectiveness in cleaning the wound without the need for new invasive procedures such as cutting and surgical debridement.

This paper presents the results of comparing data from three-dimensional electromagnetic modeling of two designs of double-gap photonic crystal resonators of a two-barrel multi-beam klystron operating in the X-band at an accelerating voltage of 3.6 kV. These resonators are designed to operate on the main π-type oscillation with an output power level of about 2 kW. They are characterized by different profiles of the beam-let tubes. Each of the beam-let tubes in these structures contains 19 beam channels arranged in linear rows. The results of optimization of the complex of electronic and electro-dynamic parameters are presented. The optimal parameters and designs of resonant systems are found, which make it possible to significantly reduce the degree of inhomogeneity of the effective characteristic resistance in the interaction space.

The block principle of constructing of coding matrices for non-absorbing flat digital anisotropic meta-coatings (MC) used to reduce monostatic RCS of objects is considered. The essence of this principle consists in 2-bit coding of the tilt angles of the anisotropy axes of the MC modules so that four arbitrary adjacent modules of the MC form two pairs of antiphase modules. The use of the block principle in the development of a MC provides a reduction of monostatic RCSs on cross polarization due to cancellation of interference waves. The reduction of the monostatic RCS of a MC at matched polarization (co-RCS) is due to the twist-effect. Simultaneously with cancellation and twist-effect, diffuse wave scattering is implemented in the developed digital MCs. The proposed 2-bit anisotropic MCs make it possible to achieve a more effective reduction of monostatic co-RCS (in relation to the traditionally accepted level of minus 10 dB) in a wide frequency band, for different polarization planes of the incident wave. The impedance and full-wave models of the two main blocks of digital anisotropic MCs are developed. An asymptotic representation of the polarization scattering matrix is obtained for the impedance model of the MC block using the method of physical optics. The algorithm for calculating the frequency characteristics (FC) of monostatic co-RCS of impedance models of MC blocks is implemented in the Octave program. Full-wave models of MC blocks are built using the HFSS program. Layouts of two main MC blocks were made. Monostatic co-RCSs of the blocks are measured in the 7÷17.5 GHz frequency band for different polarizations of the incident wave. It is shown that the calculated and measured frequency characteristics of monostatic RCS of the models and layouts of blocks of 2-bit anisotropic MCs are in good agreement. The calculated and measured levels of monostatic RCS reduction of the main blocks are at least 12.5 - 13.5 dB at different co-polarizations in the band from 10.2 to 17.5 GHz and higher (based on the results of calculations).

This article presents an algorithm for recovering radiation sources from a printed circuit board in the near field. The model of the printed circuit board is represented by the Hertz dipoles, the equations for which are known. The basis of the reconstruction algorithm is LASSO regression, which allows one to recover the parameters of radiation sources with a higher accuracy than the classical Tikhonov regularization method widely used in similar problems. To use the reconstruction algorithm, it is necessary to have experimental data on electromagnetic radiation from the printed circuit board. Such data can be obtained using a planar scan method. This article presents the experimental results of reconstructing radiation sources from a printed circuit board using the proposed algorithm.

Introduction. Hypovitaminosis D is a global public health problem. It affects children of all ages. Objective. To determine the risk factors of hypovitaminosis D in children. Population and methods. Cross-sectional study of non-supplemented children (n=123), 54 girls, and 69 boys, aged between 6-12 years. The thresholds were defined as adequacy 30 ng/mL, and deficiency 10 ng/mL. Seasons, daily sunshine duration, gender, exogenous Vit. D intakes, phototype, and body mass index (BMI) were analysed. The study was carried out during 12 months (January 2018-January 2019) with samples taken during the four seasons. Results. The median age was 8.16 ±1.82 years. Hypovitaminosis D was noted in 79.6% versus 20.4% adequacy. The average BMI was 16.80 ± 3.29kg/m2 [11.89 -30.70]. Vit. D daily intakes < 400 IU/d was noted in 52.9% of children, 75.6% of them were insufficiently exposed to sun. After multivariate analysis, and adjustment, the influencing factors were seasons (pa <0,0001, OR=11.22), and sun exposure (pa <0,001, OR=3.56). The lowest rates were present in winter, and when sunshine was < 30 min/d. There was a significant negative correlation between Vit. D values and parathormone (PTH) rate (p <0,001, r= -0.49). Conclusion. There is a high prevalence of hypovitaminosis D in scholar age children. Sun exposure could be insufficient in this urban city. Children should have adequate outdoor activities with sunlight, according to Word Health Organization (WHO) recommendations. Vit.D supplementation should be intensified, especially in winter, and diet should be enriched in Vit. D

Introduction. Without magnesium, vitamin D cannot be converted to its biolo- gically active form, a relationship that is often overlooked. Objective. The aim of this study was to estimate the frequency of hypovitaminosis D and that of hypomagnese-mia on the one hand, and to analyze the relationship between vitamin D status, magnesium, and plasma parathormone on the other hand. Population and methods. A retrospective descriptive-analytical,and epidemiological study was conducted on a 112 apparently healthy young adult subjects. For this purpose, bioassays of 25-hydroxy-vitamin D, magnesium and plasma parathormone were performed. Results. The frequency of hypovitaminosis D (serum 25-hydroxyvitamin D  30ng/mL) represented 88.39%. Hypomagnesemia affeted 43.75% of the studied population. A highly significant positive correlation was noted between plasma magnesium levels and vitamin D status of the subjects (R= 0.849; P = 0.000), whereas, a very significant negative correlation was observed between magnesium and plasma parathormone levels (R=-0.92 ; P = 0.000). Conclusion. A high frequency of hypovitamin D, a significant frequency of hypomagne-semia, and a positive correlation between plasma magnesium and vitamin D status are observed. Magnesium level is a determining factor in the variation of serum calcidiol concentrations that should be considered in the assessment of vitamin D status.
Escrituras en la Compañía de Jesús, el Libro de Consultas de Provincia y las Historias de Provincia
Authors: Cargnel Josefina
Published: December 2020

La escritura cumplió un papel muy importante dentro de la Compañía de Jesús, en la cual tomar registro de las cosas se convirtió en una necesidad de gobierno; para esto desarrolló un estricto círculo de correspondencia y de informes para fomentar y mantener la unión de la Orden. Al mismo tiempo promovía la escritura “para mostrar” a través de libros e Historias que daban cuenta del accionar de los jesuitas en el mundo conocido. Nos proponemos realizar un análisis comparativo entre el “Libro de consultas de provincia” y las Historias de Provincia escritas por Pedro Lozano en la primera mitad del siglo XVIII. Centramos nuestro análisis en la escritura y en la forma discursiva de cada uno, buscando observar el “Libro de consultas” como una mirada más cotidiana de los sucesos vividos en la Provincia que aquella fijada en las historias oficiales para acercarnos a la escritura jesuítica como un producto de “alguien” – historiador, secretario, consultor – condicionado por su lugar y su contexto, más allá del mensaje que transmite esa escritura.
Orden y violencia : políticas espaciales de la última dictadura militar argentina en Santa Fe y área de influencia (1976-1983)
Authors: Rausch Gisela Ariana , Citroni Julieta , Manassero Leticia
Published: December 2020

Conjugando los enfoques más recientes sobre la última dictadura militar argentina (1976-1983) con análisis pormenorizados sobre ciertos casos particulares, este artículo se propone considerar algunas de las políticas espaciales adoptadas por el régimen en la ciudad de Santa Fe y su área de influencia. Proyectos dirigidos a la vivienda social que continuaban tendencias previas, novedosos barrios privados para las élites y grandes proyectos de infraestructura son examinados con el recurso a distintas fuentes gubernamentales, informes de gestión y la prensa periódica local. A partir de los opuestos orden y violencia, estas acciones se conciben como orientadas a producir un nuevo espacio o a restaurar un pasado perdido, en el cual ciertos actores colectivos y sus intereses tenían mayor incidencia que otros, aunque no estaban exentos de contradicciones internas y algunos cuestionamientos.
