A case of Giant Perifollicular Fibroma - a Diagnostic Challenge
Authors: Rao Raghavendra , Srinivas Srilatha Parampalli , Shetty Varsha M.
Published: November 2020

Perifollicular fibroma (PFF) is a rare proliferative lesion originating from the perifollicular connective tissue sheath. It may be congenital or acquired manifesting as skin colored to pink, asymptomatic papules of 1-5 mm in size. They are commonly distributed in the head and neck region. Multiple PFFs may be associated with internal malignancy or as a part of Birt-Hogg-Dube syndrome. Histopathology serves as an essential tool in clinching the diagnosis. Herein we report a case of giant congenital PFF.
Controlling the Operation of a Ship’s Electric Power Supply Using Fuzzy Controllers
Authors: Żak Bogdan , Hożyń Stanisław
Published: November 2020

The paper presents dynamical models of controlling voltage and frequency of ship’s electric supply set. The simulation model of synchronous generator, implemented in Matlab/Simulink, was described. For the developed simulation model, developed control systems using fuzzy controllers type P and PD were presented. Simulation research for resistance, inductive and capacitive loads were carried out for these regulators. Sample results of simulation tests are presented in the form of voltage waveforms at the output of the generator and rotational speed of the internal combustion engine for various load conditions. The conducted tests allow to assess the quality of the control process using fuzzy controllers and thus ensure the selection of the optimal solution.
Nonhomogeneus Generalisations of Poisson Process in the Modeling of Random Processes Related to Road Accidents
Authors: Grabski Franciszek
Published: November 2020

The stochastic processes theory provides concepts, and theorems, which allow to build the probabilistic models concerning accidents. “Counting process” can be applied for modelling the number of road, sea, and railway accidents in the given time intervals. A crucial role in construction of the models plays a Poisson process and its generalizations. The nonhomogeneous Poisson process, and the corresponding nonhomogeneous compound Poisson process are applied for modelling the road accidents number, and number of people injured and killed in Polish roads. To estimate model parameters were used data coming from the annual reports of the Polish police.

Published: November 2020

After 1990, the problem of finding econometric models to assess the influence of economic development on the environment becomes a global goal, a central element of regional, national and Community policies. A perception on the evolution of global climate change and on the impact of human activity on them has been determined by the hypothesis that in the early stages of economic development, pollution and incomes are growing almost simultaneously, and beyond a certain level of incomes, the trend is reversing, therefore at high levels of incomes and economic growth occur improvements in environmental conditions. In this paper, we aim to analyze the relationship between the level of pollution (CO2 emissions) and revenues (GDP per capita) using the Kuznets Environmental Curve (EKC). To apply the econometric model, two indicators were used: CO2 emissions and GDP per capita, using a panel analysis for the period 2000 - 2016, which included 31 European countries and 527 observations. The article contributes to the development of econometric applications based on panel data and the Kuznets Environmental Curve.
Ease of Doing Business and Capital Market Development in a Demand Following Hypothesis: Evidence from ECOWAS
Authors: Nageri Kamaldeen Ibraheem
Published: November 2020

Capabilities of African businesses in a transformative role in solving the continent‘s challenges are underestimated and misunderstood. This study examined ease of doing business and financial development from a demand following hypothesis in the West African sub-region, employed Structural Equation Model covering the period of 2004 - 2017. Ten ease of doing business indicators and five distinct financial (capital market) development variables from the World Bank database were used. Findings indicate weak demand following the hypothesis of capital market development: positive and negative, depending on the measure of capital market development from the ease of doing business for West African countries majorly because of inadequate electricity. The indirect effect of the construction permit, property registration, access to credit, minority investors‘ protection and cross-border trading are indirectly significant to capital market development while starting a business, tax-paying, contract enforcement and settling insolvency are insignificant. The study recommended roadshow by West African capital markets to improve the listing of companies and the government should improve on the electricity supply.
Causality Analysis of Disaggregated FDI Inflows on Sectorial Growth in OECD Area
Authors: Ogbeifun Lawrence , Shobande Olatunji Abdul
Published: November 2020

This article revisits the link between disaggregated Foreign Direct Investment (FDI) inflows and sectorial growth using the panel dataset of 25 Organisation for Economic Co-operation and Development (OECD) countries for the period 1990 to 2017. It adopted the panel fixed effect and Feasible Generalized Least Squares Approach in its analysis. The findings show that disaggregated FDI inflows have the potential to improve growth in the OECD area with adverse effects on domestic investment and inflationary pressure. Additionally, the results further indicate that disaggregated FDI inflows have a positive and significant relationship on the service and manufacturing sector but with no evidence shown on the agricultural industry. Thus, the study concludes that efficient reallocation of FDI resource(s) among sectors will not only boost output growth but also impact on the real economy. However, the necessary policy strategy to regulate this inflow is vital to mitigate its negative impact on domestic investment and inflation pressure.
The Accuracy of the Navigational Accelerometer with a Nonlinear Metrological Model in Operating Conditions
Authors: Chernyak Mycola , Kolesnyk Vadym
Published: November 2020

A mathematical model of the error of the navigational accelerometer caused by the nonlinearity of its metrological model, taking into account the influence of vibration, was developed. The method of experimental estimation of the vibration error based on the developed model was proposed. The main idea of the method is to evaluate parameters of the developed model during static tests in the terrestrial gravitational field and to calculate error according to the specific vibration characteristics – the amplitude in the case of harmonic vibration profile or the frequency band and the power spectral density in the case of random vibration. The effectiveness of the proposed method has been tested using three types of navigation accelerometers in comparison with the results of classical dynamic testing in various vibration conditions (harmonic, white noise, etc.).
Vibration Properties of Steel Constructed Hospital Elevated Helipads
Authors: Krzymień Wiesław , Szmidt Michał , Cieślak Sławomir
Published: November 2020

Polish Medical Air Rescue helicopters facilitate the rapid transport of patients to large hospitals. The requirements of the space around the helipad and the safety of flight operations mean that hospitals closer to city centers create more elevated helipads than ground-based helipads. The helipads can vary in the way they are constructed and located - depending on the possibilities offered by hospital buildings and their surroundings.

Vibroacoustics Laboratory of the Institute of Aviation measured the vibration properties of some elevated helipads. The goal of this research was to determine the vibration properties of the helipads itself and the transmission of vibrations to the construction of the helipads, the building and its equipment caused by the landing and taking-off of a helicopter.

This article presents some of the results of measurements of vibrations of steel constructed elevated helipads with the use of a modal hammer and while landing and taking-off of a helicopter, as well as comparison of the vibration properties concerning various elevated concrete helipads.

Potencjalne koszty suburbanizacji. Zarys problematyki oraz praktyka badawcza
Authors: Dawid Wojciech
Published: November 2020

Abstrakt

Konsekwencją suburbanizacji jest szereg zmian w fizycznej przestrzeni zurbanizowanej. Niosą one za sobą wiele łatwo identyfikowalnych wynikających z nich kosztów, chociażby tych związanych z dojazdami do pracy czy też kosztami utrzymania i budowy dodatkowej infrastruktury. Na ich temat pojawiło się już wiele polskich i zagranicznych publikacji opierających się na różnorodnych wyliczeniach i metodach kalkulacji. Trudność bezpośredniego wskazania wymiaru ekonomicznego zjawiska suburbanizacji wskazuje na konieczność dalszych analiz w tym zakresie oraz szerokiego spojrzenia w istniejące już badania i opracowania pozwalające uchwycić niedostrzegalne na pierwszy rzut oka czynniki poboczne. Szczególnie wrażliwe mogą być tzw. koszty społeczne, często identyfikowalne z czynnikami wpływającymi na jakość życia mieszkańców miast i przedmieść. Zauważyć to można dzięki zróżnicowaniu szacunków w poszczególnych analizach przytoczonych w artykule. Równie trudne do wykazania mogą być także koszty środowiskowe, które naturalnie łączone są ze zjawiskiem rozlewania się miast. Analiza istniejących już badań w tym zakresie, szczególnie obszernej zagranicznej literatury przedmiotu, pozwala na wieloaspektowe spojrzenie na zjawisko suburbanizacji oraz bardziej krytyczną ocenę uproszczonych analiz pozbawionych szerszego kontekstu.

Authors: Ziółkowska Marta
Published: November 2020

Abstrakt

Badania dotyczące urbanizacji, z uwagi na jej złożony, wieloaspektowy charakter, były dotychczas przedmiotem wielu prac naukowych. Podstawy teoretyczne i metodologiczne geograficznych studiów miejskich zaczęły kształtować się w pierwszej połowie XX w., a wraz z nimi pojawiały się nowe koncepcje i orientacje badawcze oddziałujące na całą geografię społeczno-ekonomiczną. Celem artykułu jest przegląd wybranych zagranicznych i krajowych koncepcji i metod badawczych dotyczących przestrzeni zurbanizowanej, realizowanych od przełomu XIX i XX do XXI w. W pracy przedstawiono główne metody i kierunki badań nad urbanizacją. Analizie poddano dorobek i rozwój geografii osadnictwa oraz podstawy teoretyczno-metodologiczne z dziedziny studiów miejskich mające wpływ na rozwój struktur osadniczych. Zwrócono uwagę głównie na prace poświęcone przekształceniom urbanistycznym oraz studiom nad przestrzenią zurbanizowaną miast, a także na zastosowanie badań geografii osadnictwa dla celów planistycznych. Z uwagi na złożoność poruszanej problematyki w pracy odniesiono się tylko do wybranych koncepcji i metod uznanych za najbardziej znaczące z punktu widzenia badań nad urbanizacją.
Bilansowanie terenów pod zabudowę – praktyka sporządzania
Authors: Szpura Anna
Published: November 2020

Abstrakt

Bilans terenów przeznaczonych pod zabudowę jest jedną z ważniejszych analiz, którą należy wykonać w związku z opracowaniem studium uwarunkowań i kierunków zagospodarowania przestrzennego gminy. Jego wynik decyduje o dalszym losie opracowywanej polityki przestrzennej. Wykazanie niedoboru terenów do zabudowy pozwala uwzględniać wnioski inwestorów i wskazywać nowe tereny na cele budowlane. Nadmiar terenów do zabudowy w studium stawia gminę w trudnej sytuacji, gdyż blokuje możliwość wyznaczania nowych terenów na cele inwestycyjne. Art. 10 ust. 5 ustawy o planowaniu i zagospodarowaniu przestrzennym zawiera nieprecyzyjne normy co do sposobu przeprowadzenia bilansu terenu, co rodzi szereg problemów aplikacyjnych. Artykuł stanowi głos w dyskusji prowadzonej w środowiskach naukowych i eksperckich dotyczącej poszukiwania optymalnych metod bilansowania terenów zgodnych z wymogami prawnymi oraz mających na uwadze interes samorządów. W pracy skupiono się wyłącznie na metodach bilansowania terenów na cele mieszkaniowe.
Trends in a State Pharmaceutical Assistance Program for Low-income Older Adults in Wisconsin
Authors: Look Kevin , Kim Nam Hyo , Dague Laura , Winn Aaron
Published: November 2020

Introduction: Many older adults face difficulty in affording their prescription drugs, despite having coverage available through Medicare Part D. SeniorCare is Wisconsin’s pharmaceutical assistance program that provides comprehensive drug coverage for low-income older adults who are not eligible for full Medicaid benefits.
Methods: We analyzed SeniorCare enrollment and pharmacy claims data from 2014 to 2018.
Results: Total drug expenditures increased by 19.3%, with the proportion of expenditures paid by SeniorCare and members decreasing while the proportion paid by other payers increased. Specialty drugs accounted for a substantial and growing proportion of total expenditures (20.4% in 2018) despite accounting for <0.2% of all claims.
Conclusions: Total drug expenditures in SeniorCare have steadily increased over time, primarily due to rising average expenditures per drug fill and increased use of specialty drugs. However, SeniorCare members have been largely protected from these increases and have paid a decreasing proportion of costs over time.

Eco-Cosmopolitan Strangers: Migration, Toxicity and Vulnerability in the US-Mexico Border Through a Revision of Lucha Corpi’s Cactus Blood
Authors:   University of Oviedo (España), Pérez Ramos María Isabel
Published: November 2020

Migration flows are common in the US-Mexico border region. However, it has never been so complicated for Latinas/os to cross northwards as it is today. This is due not only to political factors, but also to worsening environmental conditions. Migration, environmental degradation, toxicity and vulnerability are all entangled issues in the US-Mexico border region, as Lucha Corpi’s novel Cactus Blood (1995) depicts. When analyzed from an eco-cosmopolitan perspective, the migrant character in the novel, understood as a “stranger”–in the sense of an in-between, insider-outsider character that makes boundaries porous–discloses an environmental awareness that she can use to face her own vulnerability, while at the same time revealing the (global) networks responsible for the environmental degradation and toxicity of certain places, such as the US-Mexico border region. A socio-environmental revision of Cactus Blood–a novel written a quarter of a century ago–highlights issues that are extremely pertinent to confront contemporary challenges.
Immersion Through Culture: Representations of the “Day of the Dead” in Film
Authors:   Aristotle University of Thessaloniki, Greece, Dimitriadis Giorgos
Published: November 2020

The Mexican celebration of the “Day of the Dead” (Día de Muertos or Día de los Muertos) has been recurrently used in film, with three of the most notable examples ranging from the recent Coco (Lee Unkrich and Adrian Molina, 2017) and Spectre (Sam Mendes, 2015), all the way back to the surviving footage of ¡Que Viva Mexico! (Sergei Eisenstein, 1931, unfinished). Though vastly different from one another in almost every respect, all three cases explore the topic of “in-between” both thematically and technically: the celebration that merges life and death becomes a visual metaphor and a tool for filmmakers to explore the ways in which film technique creates overlapping areas between cinema and reality. In each film, a visually powerful cultural asset such as the “Day of the Dead,” is combined with different aspects of film technique, explicitly, but differently, appealing to a kind of sensory immersion in order to attract viewers inside its world. By doing so, the “Day of the Dead” exemplifies the ways in which a common cultural element can help translate the personal visions of different filmmakers into distinct filmic events.
Visions of Aztlán: The Chicano Documentary Film
Authors:   Centro de Investigación y Docencia Económicas (CIDE), México, Maciel David R.
Published: November 2020

In the decade of the 1960s and 1970s, a trascendental social movement –which was known as the Chicano Movement for Civil Rights– took place in the United States. One of its major achievements was a cultural flowering that encompassed all the art forms and practices. Among them, one of single importance is the documentary film. This article presents an overview of the origins, first steps and current developments of the Chicana/o documentary cinema. Such films address a multitude of topics and combine highly artistic value with a definite political message. In addition, the Chicana/o documentary is an outstanding and highly informative mirror into Chicano experience. Since its inception to the present, over 100 documentaries have been produced and exhibited in the US, yet they have not been well-distributed in the Spanish-speaking world.
Towards a Geography of trauma: From El plan spiritual de Aztlán to the Birth of Chicana Spìritual Feminism
Authors:   The Bucharest University of Economic Studies (Rumanía), Got Monica
Published: November 2020

The paper explores the unbreakable link between Chicana literature and its political/ ideological/militant/subversive component, based on a new interpretation of “cultural nationalism.” Explaining the sociopolitical motivations that led to the California student revolts of the 1960s and the Chicana Movement’s Plan Espiritual de Aztlán, I also discuss the ensuing falling-out between the feminine/feminist faction of the Movement and its androcentric majority. I draw on the formal/conceptual/linguistic hybridity of Gloria Anzaldúa’s Borderlands/La Frontera as a metaphor for the radical character of the entire Chicana literary phenomenon.
Service-Learning as Part of the L2 Spanish Classroom in Canada

Published: November 2020

Service-learning in foreign language classrooms is an effective resource for developing language motivation. Unfortunately, Canadian language programs have been off to a slow start in adopting integrative teaching such as service-learning in their foreign language curricula (Hale, 1999). This work reports on a Community Service Learning (CSL) initiative introduced at a Canadian university in the Hispanic Studies program. A total of fifty second and third year Spanish language students volunteered with various community partners on a weekly basis for a total of sixteen weeks. End-of-term questionnaire indicates that overall students had a favorable experience at their placement and CSL had a positive influence in continuing their studies in Spanish.
Roughing It in the Bush, The Graphic Novel
Authors:   Universidad de Córdoba (España), Martín Párraga Javier
Published: November 2020

Graphic novels and comic books are no longer minor cultural artifacts which are produced to generate economic benefits, mostly consumed by young, not very literate, readers who do not hope to be educated but simply entertained. Quite on the contrary, authors such as Will Eisner, Art Spiegelman, Alan Moore, Neil Gaiman or Umberto Eco has vindicated the fundamental role these artistic manifestations play nowadays. The present paper analyzes Carol Shields and Patrick Crowe 2016 graphic novel adaptation of Susanna Moodie’s seminal book Roughing it in the Bush. In order to reach this goal, a brief theoretical state of the art is introduced. Consequently, the original writer and text are equally studied. Finally, the contemporary graphic novel adaptation is considered, explaining the genesis of the project as well and the similitudes and differences it shows when compared to the original work by Susanna Moodie.
Rhodes and the Spatial Realisation of Race, Gender and Sexuality
Authors: Van der Wal Ernst
Published: November 2020

The call for the decolonisation of South African space that started to resound throughout South Africa in 2015 has, for a large part, centred on the institutional and historical legacy of Cecil John Rhodes. The Rhodes Must Fall movement has, for example, demonstrated the degree to which Rhodes is still entangled with the South African landscape. Although this movement has largely exposed the race-based prejudices of Rhodes’ imperialist endeavours for South(ern) Africa, Rhodes’ legacy also carries overt biases towards gender and sexuality. As this article demonstrates, the spectre of Rhodes’ alleged homosexuality has haunted him not only during his lifetime, but has persisted to the present day. The concept of Rhodes as a homosexual man stands in a complex relationship to the public image of imperialist, statesman and entrepreneur that he and key agents in the British Empire have tried to foster. However, in the wake of a crumbling British Empire, Rhodes have been left exposed to critics who have strategically used him as an example of the way in which decolonisation can be exacted upon a memorialised legacy. As this article demonstrates, Rhodes’ entanglement with the ideas surrounding race, gender and sexuality that were prevalent during his life had a direct impact on his conduct in South Africa. When it comes to the active decolonisation of South African spaces and institutional discourses, Rhodes’ whiteness, masculinity and possible homosexuality present a complex picture of the history of empire-building – of British dreams to paint Africa red.
What do neurosurgical trainees think about neuro-interventional training and service provision in the United Kingdom?
Authors: Kotecha Jay , Hollingworth Milo , Patel Hiren C. , Lenthall Robert
Published: November 2020

Background:

There is a disparity between the number of interventional neuroradiologists (INRs) in the UK and the number needed to provide a comprehensive 24/7 interventional neurovascular service. It is recognized that trainees from other specialties such as neurosurgery may be able to provide INR services after appropriate training. At present gaining skills in INR is not a mandatory requirement of the neurosurgical training curriculum in the UK. The views on this issue of current neurosurgical trainees are unknown. We aimed to address this knowledge gap.

Methods:

We performed an anonymized online survey to gauge the opinion of neurosurgical trainees about their attitudes to INR training and service provision.

Results:

90/265 (34%) UK neurosurgical trainees responded to the survey. About 56% of respondents reported they were likely or very likely to pursue interventional training if a curriculum was approved by the general medical council. About 80% thought training should take up to 2 years. About 90% of those very likely or likely to pursue INR wanted a hybrid neurosurgical practice and 92% were willing to provide endovascular services out of hours.

Conclusion:

The responses described suggest that a significant proportion of neurosurgical trainees would pursue INR training and have realistic expectation regarding out of hours commitment and length of training.
Comparison of TruView and King Vision video laryngoscopes in subaxial cervical spine injury: A randomized controlled trial
Authors: Sen Rupanwita , Mallepally Abhinandan Reddy , Sakrikar Gayatri , Marathe Nandan , Rathod Tushar
Published: November 2020

Background:

Airway management with cervical spine immobilization poses a particular challenge for intubation in the absence of neck extension and risks neurological damage in cases of unstable cervical spine injuries. Here, with manual inline stabilization (MILS) in patients with cervical spine injuries, we compared the safety/efficacy of intubation utilizing the TruView versus King Vision video laryngoscopes.

Methods:

This prospective, single-blind, comparative study was conducted over a 3-year period. The study population included 60 American Society of Anesthesiologists (ASA) Grade I-III patients, aged 18–65 years, who underwent subaxial cervical spine surgery utilizing two intubation techniques; TruView (TV) versus King Vision (KV). For both groups, relative intubation difficulty scores (IDS), total duration of intubation, hemodynamic changes, and other complications (e.g., soft-tissue injury and neurological deterioration) were recorded.

Results:

With MILS, patients in the KV group had statistically significant lower IDS (0.70 ± 1.02) and significantly shorter duration of intubation as compared to the TV group (1.67 ± 1.27) with MILS (P = 0.0010); notably, the glottic exposure was similar in both groups. The complication rate (e.g., soft-tissue injury) was lower for the KV group, but this was not statistically significant. Interestingly, no patient from either group exhibited increased neurological deterioration attributable to the method of intubation.

Conclusion:

King Vision has several advantages over TruView for intubating patients who have sustained cervical spine trauma. Nevertheless, both laryngoscopes afford comparable glottic views and safety profiles with similar alterations in hemodynamics.

Authors: Isolan Gustavo Rassier , Stefani Marco Antonio , Schneider Felipe Luis , Claudino Humberto Alves , Yu Yang Han , Choi Gil Goulart , Telles Joao Paulo Mota , Rabelo Nícollas Nunes , Figueiredo Eberval Gadelha
Published: November 2020

Background:

Anatomy of the hippocampal arterial supply is key to successful surgeries in this area. The goal of the current study is to present the results we obtained from our microsurgical dissections of the temporal lobe and to propose a new classification for the hippocampal arteries (HAs).

Methods:

Fifty-six brain hemispheres were analyzed. All dissections in this study were made using 3–40× at the surgical microscope.

Results:

The hippocampal arterial vasculature can be divided into six groups, according to their frequencies: Group A: mixed arterial vasculature originating from the anterior choroidal artery anterior choroidal artery, posterior cerebral artery (PCA), anterior infratemporal artery (AIA), and splenic artery (SA). Group B: Main origin at the temporal branches – main inferotemporal trunk, middle inferotemporal artery, posterior inferotemporal artery, AIA, or main branch of PCA. Group C: AIA as the main branch of the hippocampus. Group D: HAs originating from the main branch of PCA. Group E: A single hippocampal artery with the origin at the main branch of PCA. This single artery covered all of the structure and is named Ushimura’s artery. Group F: The hippocampal vessels arose exclusively from the parieto-occipital artery, calcarine artery (CA), and the SA.

Conclusion:

This study proposes a new classification for the hippocampal vascularization, according to the origin of HAs. One of the groups has not yet been described in the literature – in which the HAs arise from the parieto-occipital artery, SA, and CA.

Sacralization of Ostroh as a result of the establishment of the topos of the "God-saved hail" (according to documentary sources of the last quarter of the 16 century)
Authors: Tymoshenko Leonid
Published: November 2020

Поширення топосу Богоспасаємого граду вписуються в теорію ієротопії, тобто сакральних просторів, в яких побутує реальна присутність Бога, невіддільна від чудотворності. Автор розглядає випадки використання цього топосу в рукописних і друкованих джерелах на прикладі Луцька й Острога – міст, що були одними з найбільших на Волині релігійними центрами, столицями Луцької і Острозької єпархії Київської митрополії. Якщо сакралізації Острога сприяла його слава як центру Волинських Афін зі знеменитою Академією та друкарнею, місця видання біблійних текстів, серед яких виокремлюється знаменита Біблія, то сакралізація Луцька може пов’язуватись з діяльністю Хрестовоздвиженського братства, а також численних монастирів і храмів. Автор припускає, що поширення топосу Богоспасаємого граду на ряд міст вело до формування своєрідного національного культурно-релігійного коду, який об’єднував українців і білорусів. Водночас, відбувалася сакралізація міст, і не тільки столичного характеру.
Library in the Unadapted Premises: Development of Architectural Transformation of Space
Authors: Kolesnikova Marina N. , Timonin Vadim P.
Published: November 2020

Siting, reconstruction, modernization of libraries in the unadapted premises has always been and remains till now a challenging practical problem in the global librarianship, which in each case obtains unique, unconventional solution. Soviet architects involved in the design of libraries — F.N. Pashchenko, L.Z. Amlinsky, V.G. Gelfreikh, A.R. Zimonenko and others — contributed to the development of this problem. They laid the modern and progressive theoretical and methodological foundations of the interdisciplinary section of library science — architecture and construction of library buildings which is actively developing in the 21st century, making the transition from the long-standing concept of the library as a repository for books to understanding it as a constantly changing, flexible and technological information space for all its subjects — visitors, readers and employees. Actualization of the complex task of creating a comfortable environment for the reader and librarian in the adopted for this purpose architectural space has come to the fore. The purpose of the article is to present an original approach in the pre-project study of the University library located in the Palace building in the form of an individual matrix of ideas and solutions. For the key conceptual ideas in the matrix of possible redesigning of the University scientific library the authors chose human centrism, openness, mobility and uniqueness. The paper presents architectural plans of the library, performed by master’s students of the St. Petersburg State Art and Industry Academy named after A.L. Stieglitz under the guidance of the architect-artist, Professor V.P. Timonin, as well as the matrix of ideas and possible solutions for the transformation of the material space of the library of the St. Petersburg State Institute of Culture, prepared by Professor M.N. Kolesnikova. The results of this work are of practical interest from the point of view of architectural design of libraries in the premises of historical buildings, that is an urgent global problem, as well as of theoretical interest for the development of modern library science in its sections related to library design, material and technical base of libraries and library imageology.

Published: November 2020

The author considers the problem of including unpublished digital scientific documents published on the websites of scientific institutions of the Russian Academy of Sciences (RAS) in the system of library and information services. The paper describes the study of this class of information objects conducted in May — June 2020 on 200 websites of academic institutions of social and humanitarian profile. The author discovered the unpublished scientific materials of socio-humanitarian profile on the websites of 158 institutions; five institutions had no websites or did not work; and 37 websites didn’t have the materials the author was looking for. The research is based on the data included in the Navigator of information resources on social Sciences (NIRON), developed at the Institute of Scientific Information on Social Sciences of the Russian Academy of Sciences (INION RAS). The author proposes classification of unpublished documents, which includes both well-known types of scientific documents, such as dissertations and reports on research work, which processing is regulated, and new types, specific for modern scientific communication, such as overviews on activities of institutions and scientific departments. In total, the described class of unpublished scientific documents consists of 10 types, some of them are divided into subtypes. The paper discloses the quantitative data of the conducted accounting, including distribution of documents by the retrospective depth. For scientific reports, the author made the comparison with the data on reports in the Unified state information system for recording the results of research, development and technological works for civil purposes. The article analyses the specific features of presenting different types of unpublished scientific materials on the websites. The author proposes to include these documents in the service system using the information-reference system. When designing such a system, many controversial issues arise, in particular: the problems of metadata, the choice of subject classification, determination of the exact composition of unpublished digital scientific documents, unification of the retrospective depth, the feasibility of their reworking and editing for unification, inclusion of unpublished documents in bibliographic databases and lists, and the possibility of using them in the anti-plagiarism system. These and other problems require further research and solutions.

Authors: Cruz Pérez Miguel Alejandro
Published: November 2020

El presente artículo se basa en una propuesta metodológica para el empleo del software educativo como recurso didáctico, dirigido a la formación investigativa en estudiantes universitarios con la finalidad de suscitar su comprensión en la actividad investigativa. La metodología empleada en el estudio parte de lo inductivo para descubrir los hechos particulares, analítico en la realización del análisis de la información teórica y los datos empíricos, el sintético en la determinación de las conclusiones pertinentes; el sistémico estructural funcional facilita concebir la propuesta metodológica. Se empleó la estadística descriptiva e inferencial, para ponderar frecuencias y obtener porcentajes de los datos empíricos obtenidos en la observación a clases; se determina el nivel de aplicabilidad de la propuesta a partir de la prueba no paramétrica de Kendall aplicado a 10 especialistas, y se analiza desde un nivel de significación del 5% lo cual representa un 95% de confiabilidad.  La investigación fue de tipo descriptiva, explicativa y proyectiva, porque permite describir, explicar la problemática y proyectar la propuesta hacia una posible solución. Se concluye que los docentes necesitan de una propuesta metodológica que permita el reconocimiento y empleo del software educativo como recurso didáctico que facilita el desarrollo de la formación investigativa.
Impacto de la tecnología en la sociedad: el caso de Ecuador
Authors: Luque González Arturo , Galora de Mora Raúl Pavlov
Published: November 2020

Los continuos avances tecnológicos condicionan la forma de interactuar y comunicarse en las sociedades posmodernas. En esta investigación, se llevan a cabo dos análisis, uno cualitativo que abarca el estudio comparativo de las bondades y deficiencias del uso de diferentes tecnologías; y uno cuantitativo, en el que se aplica un cuestionario a una muestra de cien sujetos con la finalidad de analizar los impactos de la tecnología en la sociedad, así como indagar en el uso de la telefonía móvil y redes sociales en situaciones de comunicación interpersonal. Los resultados desvelan que la mitad de los jóvenes universitarios ambateños se sienten molestos cuando su interlocutor prefiere la comunicación virtual en lugar de la personal, concomitante al hecho de no poder cesar el estado conectado semi permanente. El uso –y abuso– de tecnologías y conexión a redes sociales estudiado indica una falta de control sobre los mismos.

Published: November 2020

En el artículo se analiza la opinión de los estudiantes de la Universidad Nacional de Educación (UNAE) acerca de las tutorías, los proyectos integradores de saberes (PIENSA) y la relación de las asignaturas con la Práctica Preprofesional (PP). Para la muestra, escogida de manera no aleatoria, se convocó a un grupo focal a los representantes de cada uno de los paralelos (25 en total) de las 4 carreras: 15 participantes de Educación Básica (EB), 4 de Educación Intercultural Bilingüe (EIB), 4 de Educación Inicial (EI) y 2 de Educación Especial (EE). La recolección de información se realizó durante dos encuentros: en el primer día acudieron 9 participantes de EB y en el segundo día 5 participantes de EI, EIB y EE. El propósito de estos grupos focales es contrastar las opiniones de los estudiantes con el modelo pedagógico de la UNAE y aspectos teóricos-conceptuales afines. Como conclusión se destacan aspectos sobre cómo desarrollan las tutorías y se identifican también algunos aspectos a mejorar.
Investigación evaluativa para la inclusión educativa
Authors: Garduño Teliz Elvia , Albarrán Millán Delia Faustina , Damián Julián Fernando
Published: November 2020

El objetivo es evaluar los procesos inclusivos en la Escuela Superior Ciencias de la Educación de la Universidad Autónoma de Guerrero para mejorar el plan de estudios vigente. Con base en el índice de inclusión de la Universidad de Bristol el estudio aborda tres categorías: cultura, políticas y prácticas inclusivas. La investigación es evaluativa en tres fases: diagnóstico, comparación, y evaluación. En un trabajo anterior, se difundieron los resultados de la fase de diagnóstico; ahora se presenta la fase de comparación con un enfoque cualitativo para responder la pregunta de investigación ¿Cómo implantar los procesos de inclusión educativa en el plan de estudios?  se analizaron observaciones, entrevistas, programas de estudio y fotografías de espacios e interacciones escolares. En la cultura, los resultados demuestran la necesidad de relacionar contenidos de aprendizaje, intereses personales y de la comunidad escolar, realizar adaptaciones curriculares e integrar lenguaje inclusivo en los valores escolares. En las políticas, se precisa la integralidad mediante la participación y la difusión de buenas prácticas. En las prácticas, se requiere reducir las brechas que inciden en las interacciones y aprendizaje escolar.  Finalmente, se propone una serie de acciones para formar, sensibilizar y concientizar a la comunidad escolar en el tránsito hacia la escuela inclusiva

Published: November 2020

El presente trabajo proyecta la realidad a la que se enfrentan las personas con discapacidad visual en la práctica de actividades acuáticas, la inclusión de dichas personas al ámbito deportivo sigue siendo un obstáculo debido a la falta de promoción de estas actividades por parte de instituciones deportivas competentes. Esta investigación tiene como finalidad enseñar natación a personas con discapacidad visual que nunca han tenido la oportunidad de practicar este deporte, con el propósito de conocer las dificultades que presentan los no videntes que asisten a la fundación Dr. Oswaldo Loor. No se aplica cálculo muestral debido a que la población total fueron 11 personas, el instrumento empleado para la obtención de información fue una prueba de diagnóstico, además se aplicó una investigación exploratoria y de campo, posteriormente se ejecutó una estrategia metodológica para enseñanzar la natación, apoyándonos con bibliografía relacionada a nuestra investigación, al momento de su ejecución se elaboraron: planes de clase y test de observación, dando cumplimiento al objetivo planteado en las etapas de enseñanza. Los resultados demostraron que se cumplió la hipótesis, logrando que los alumnos aprendieran a nadar; dejando claro que, a pesar de su deficiencia visual, desarrollaron diferentes destrezas requeridas en este deporte.

Authors: Chávez García Debbie , Vera Vera Joseph , Acosta Lozano Néstor
Published: November 2020

El uso de anabólicos como promotores de crecimiento en producción de especies menores ha resultado rentable demostrado por investigaciones previas realizadas a nivel nacional e internacionalmente, para lo cual se establece el presente ensayo en la provincia de Santa Elena. Para esta investigación se establecieron 4 tratamientos con diferentes dosis de boldenona definidos como: T1= 0,025ml, T2 = 0,035ml, T3 = 0,045ml y T4 = testigo; cada uno con 7 repeticiones. El régimen alimenticio fue a base de alfalfa como forraje fresco dosificado según las etapas de producción de los cuyes. Las variables a evaluar en este ensayo son el consumo de alimento (CA), ganancia de peso (GP), índice de conversión alimenticia (ICA) y la relación beneficio/costo por cada gramo de carne en pie producida, las mismas que fueron evaluadas de manera semanal. En base a los resultados obtenidos se destaca que el mejor tratamiento respecto a las variables de GP y CA es el T2 en donde se alcanzaron valores de 1053,42g/ff/semanal y 17,82g/semanal por tratamiento; el mejor valor de ICA se obtuvo en el T4 con 3,9. El mejor tratamiento en cuanto al costo por gramo de carne en pie producido es el T1 (0,025ml) con un costo de $0,02g de carne por semana. Finalmente, las variables evaluadas no presentan diferencias estadísticas significativas, pero en la práctica las ganancias de peso e índices de conversión alimenticia que se obtuvieron representan rentabilidad productividad para los sistemas de explotación de estas especies.

Con la finalidad de incrementar el conocimiento sobre los cnidarios se estudió la composición, distribución, abundancia y ecología de la comunidad de medusas y sifonóforos durante la época húmeda desde diciembre del 2015 a mayo del 2016 en seis estaciones ubicadas en la zona costera de Ancón, Anconcito y Punta Carnero (Ecuador), a partir de 51 muestras zooplanctónicas colectadas mediante arrastres superficiales y verticales. Se identificaron 22 especies de medusas clasificadas en 5 órdenes, 14 familias y 16 géneros y 14 especies de sifonóforos con 1 orden, 2 subórdenes, 4 familias y 10 géneros. Las especies más abundantes a nivel superficial fueron Aglaura hemistoma en febrero, Liriope tetraphylla en marzo, Obelia sp. y Proboscidactyla ornata en febrero, Nanomia bijuga en abril, Muggiaea atlantica en febrero, Sulculeolaria chuni y Diphyes dispar en marzo, mientras que en la columna de agua (10 metros) fueron Proboscidactyla ornata en febrero, Liriope tetraphylla, Solmundella bitentaculata, Obelia sp., Muggiaea atlantica y Nanomia bijuga en abril, la máxima diversidad en medusas fue de 2.14 bits/ind en la columna de agua para abril, mientras que en sifonóforos a nivel superficial con 1.67 bits/ind para diciembre. La similitud de Bray-Curtis determinó a las estaciones E2, E3 y E4 como las más afines por sus máximas abundancias. El análisis de correspondencia canónica destacó la relación entre Obelia sp. y Muggiaea atlantica con la temperatura y de Liriope tetraphylla con la salinidad. En general, la fauna de medusas y sifonóforos mostró una representativa afinidad ecológica para aguas tropicales y subtropicales así como también presencia de especies cosmopolitas, neríticas y oceánicas, estudio de vital importancia para asociarlos en futuras investigaciones al Evento El Niño.
