Micromechanisms leading to shear failure of Opalinus Clay in a triaxial test: a high-resolution BIB–SEM study
Authors: Winhausen Lisa , Klaver Jop , Schmatz Joyce , Desbois Guillaume , Urai Janos L. , Amann Florian , Nussbaum Christophe
Published: September 2021

Abstract. A microphysics-based understanding of mechanical and
hydraulic processes in clay shales is required for developing advanced
constitutive models, which can be extrapolated to long-term deformation.
Although many geomechanical tests have been performed to characterise the
bulk mechanical, hydro-mechanical, and failure behaviour of Opalinus Clay,
important questions remain about micromechanisms: how do microstructural
evolution and deformation mechanisms control the complex rheology? What is
the in situ microstructural shear evolution, and can it be mimicked in the
laboratory? In this contribution, scanning electron microscopy (SEM) was
used to image microstructures in an Opalinus Clay sample deformed in an
unconsolidated–undrained triaxial compression test at 4 MPa confining stress
followed by argon broad ion beam (BIB) polishing. Axial load was applied
(sub-)perpendicular to bedding until the sample failed. The test was
terminated at an axial strain of 1.35 %. Volumetric strain measurements
showed bulk compaction throughout the compression test. Observations on the
centimetre to micrometre scale showed that the samples exhibited shear failure and
that deformation localised by forming a network of micrometre-wide fractures,
which are oriented with angles of 50∘ with respect to horizontal.
In BIB–SEM at the grain scale, macroscale fractures are shown to be
incipient shear bands, which show dilatant intergranular and intragranular
microfracturing, granular flow, bending of phyllosilicate grains, and pore
collapse in fossils. Outside these zones, no deformation microstructures
were observed, indicating only localised permanent deformation. Thus,
micromechanisms of deformation appear to be controlled by both brittle and
ductile processes along preferred deformation bands. Anastomosing networks
of fractures develop into the main deformation bands with widths up to tens
of micrometres along which the sample fails. Microstructural observations and
the stress–strain behaviour were integrated into a deformation model with
three different stages of damage accumulation representative for the
deformation of the compressed Opalinus Clay sample. Results on the
microscale explain how the sample locally dilates, while bulk measurement
shows compaction, with an inferred major effect on permeability by an
increase in hydraulic conductivity within the deformation band. Comparison
with the microstructure of highly strained Opalinus Clay in fault zones
shows partial similarity and suggests that during long-term deformation
additional solution–precipitation processes operate.
Impact of the wind field at the complex terrain site Perdigão on the surface pressure fluctuations of a wind turbine
Authors: Wenz Florian , Langner Judith , Lutz Thorsten , Krämer Ewald
Published: September 2021

Abstract. The influence of turbulent inflow, as it occurs in complex terrain, on the unsteady surface pressure distributions on a wind turbine is investigated numerically. A method is presented that enables an accurate reproduction of the inflow to the turbine in the complex terrain in Perdigao, Portugal. For this purpose, a precursor simulation with the steady-state atmospheric computational fluid dynamics (CFD) code E-Wind and a high-resolution Delayed Detached Eddy Simulation (DDES) with FLOWer is performed. The conservation of the flow field is validated by a comparison with measurements from the 2017 field campaign in Perdigao. Then, the resolved fluid-structure coupled generic wind turbine I82 is included in the FLOWer simulation to investigate the impact of the complex terrain inflow on the surface pressure fluctuations on tower and blades. A comparison with simulations of the same turbine in flat terrain with simpler inflows shows that the turbine in complex terrain has a significantly different vortex shedding at the tower, which dominates the periodic pressure fluctuations at the tower sides and back. However, the dominant source of periodic pressure fluctuations on the upper part of the tower, the blade-tower interaction, is hardly altered by the terrain flow. The pressure fluctuations on the blade have a rather broadband characteristic, caused by the interaction of the leading edge with the inflow turbulence. In general, it is shown that a sophisticated DDES of the complex terrain plays a decisive role in the unsteady aerodynamics of the turbine, due to its specific flow characteristic.
Local thermal gradient and large-scale circulation impacts on turbine-height wind speed forecasting over the Columbia Basin
Authors: Liu Ye , Qian Yun , Berg Larry K.
Published: September 2021

Abstract. We investigate the sensitivity of turbine-height wind speed forecast to initial condition (IC) uncertainties over the Columbia River Gorge (CRG) and Columbia River Basin (CRB) for two typical weather phenomena, i.e., local thermal gradient induced marine air intrusion and a cold frontal passage. Four types of turbine-height wind forecast anomalies and their associated IC uncertainties related to local thermal gradients and large-scale circulations are identified using the self-organizing map (SOM) technique. The four SOM types are categorized into two patterns, each accounting for half of the ensemble members. The first pattern corresponds to IC uncertainties that alter the wind forecast through modulating weather system, which produces the strongest wind anomalies in the CRG and CRB. In the second pattern, the moderate local thermal gradient and large-scale circulation uncertainties jointly contribute to wind forecast anomaly. We analyze the cross-section of wind and temperature anomalies through the gorge to explore the evolution of vertical features of each SOM type. The turbine-height wind anomalies induced by large-scale IC uncertainties are more concentrated near the front. In contrast, turbine-height wind anomalies induced by the local IC thermal uncertainties are found above the surface thermal anomalies. Moreover, the wind forecast accuracy in the CRG and CRB are limited by IC uncertainties in a few specific regions, e.g., the 2-m temperature within the basin and large-scale circulation over the northeast Pacific around 140° W.

Two-Year Retrospective Evaluation of Anti-DFS70 Antibody Positive Cases in a University Hospital
Authors: Aksoy Rahime , Us Ebru
Published: September 2021

Objective: The presence of anti-nuclear antibodies (ANA) are important indicators of systemic connective tissue diseases. Anti-DFS70 autoantibody is also known to be found in healthy individuals and has not yet been identified in relation with diseases. The aim of our study was to investigate the relationship between clinical complaints, diagnoses and inflammation parameters [C-reactive protein (CRP), erythrocyte sedimentation rate (ESR) and rheumatoid factor (RF)] of patients with anti-DFS70 antibody positivity detected by Indirect Immune Fluorescent-ANA (IIFANA) and Immunoblot method. Method: A total of 450 patients, 412 (91.5%) women and 38 (8.5%) men, between the ages of 4–90, were included in the study. The clinical diagnoses and inflammation parameters of the patients were evaluated retrospectively. Results: Complaints were pain (126/136) and rash, dyspnea, pruritus (10/136). While inflammation was not detected in 81 (64.3%) of the patients with pain complaints, it was found in 45 (35.7%) and was found to be statistically significant (p=0.001). Inflammation was found to be negative in 106 (67.9%) patients with systemic involvement of connective tissue, positive in 50 (32.1%) patients (p<0.001), negative in 19 (95%) and positive in 1 (5%) patients with urticaria (p<0.001). Ten of the 60 patients with a definitive diagnosis had systemic involvement of the connective tissue, 10 had urticaria, and 40 had different diagnoses. Conclusion: It was concluded that DFS70 positivity was higher in women and this pattern may accompany many diseases. Our study suggests that the cause of pain may be the DFS70 antibody when inflammation parameters are eliminated, and that there may be a relationship between urticaria and DFS70 autoantibodies.

Zur Wiederentdeckung einer Kantate Gioachino Rossinis in Berlin
Authors: Joerg Guido Johannes
Published: September 2021

Die "Cantata per Sampieri" (Bologna 1830) wurde im September 1991 in Berlin wiederentdeckt. Einer Beschreibung der Partiturhandschrift folgt die Analyse der Besetzung, der Besonderheiten der Instrumentierung, des Textes, der Entstehungsgeschichte und der ersten Aufführung der Kantate als Geschenk zum Namenstag des Bologneser Marchese Francesco Sampieri. In der musikalischen Analyse zeigen sich die Einflüsse durch die Kantate "La riconoscenza" und die Bühnenwerke "Aureliano in Palmira" und "Le comte Ory". Die Kantate dient als Argumentationshilfe gegen die Vorstellung, daß Rossini nach dem "Guillaume Tell" nicht mehr komponiert habe. (Joerg, Guido Johannes)

Alexander Skrjabin: Die 6. Klaviersonate op. 62
Authors: Willmann Roland
Published: September 2021

Als Musik historischen Übergangs erweist sich die 6. Sonate Skrjabins. Oktatonik vermittelt noch unverbrauchten Ausdruck und ist schon einheitsstiftendes Strukturprinzip. Die Sonatensatzform wird einer prozeßhaften Dynamik unterworfen, indem sich die Musik mittels klanglich-linearer Dialektik entfaltet. Thematische Gestalten profilieren sich, die auf einer höheren Entwicklungsstufe wiederum zur Synthese gelangen. Eine Analogiebildung zu geistigen Prinzipien schein möglich. Der von Friedrich Nietzsche formulierte dionysisch-apollinische Gegensatz erscheint in der 6. Sonate sogar explizit: Als apollinische Welt des Traums und als dionysische Sphäre von Rausch und Tanz.

„Daß deines Namens Ruhm in Deutschland bald angehn... wird”
Authors: Heyink Rainer
Published: September 2021

In den 1660er und 70er Jahren dürfte Johann Rosenmüller im Musikleben Venedigs eine bevorzugte Stellung eingenommen haben, wo er für die prunkvollen Vespergottesdienste der venezianischen Kirchen viele großangelegte Konzerte schrieb. Mit Hilfe von Rondoschemata, wiederholt auftretenden Instrumentalritornellen und dem thematischen Zusammenhang zwischen Psalmbeginn und abschließender Doxologie erreicht Rosenmüller einheitliche, in sich geschlossene musikalische Formen. Auch kann kein Zweifel bestehen, daß die deutsche Musik im späten 17. Jahrhundert von Rosenmüllers Werken entscheidende Impulse empfangen hat.
süddeutsches Tropar-Fragment
Authors: Schier Volker
Published: September 2021

Das Bistumsarchiv der Diözese Augsburg beherbergt ein wahrscheinlich süddeutsches fragmentarisches Graduale aus der ersten Hälfte des 12. Jahrhunderts, das auf Blatt 7 recto einen kurzen Tropar enthält. Verzeichnet sind im Tropar Gesänge zum Weihnachtsfest, zum Fest des hl. Stephanus und zum Fest des hl. Johannes. Sowohl das Repertoire wie auch die melodischen Lesarten lassen sich in identischer Form in keiner weiteren Quelle aufzeigen. Der Tropus  im Stephanus-Formular deutet auf eine Verbindung der aufgezeichneten Praxis nach St. Gallen und Eichstätt hin. Die Position dieses Tropus innerhalb des wohl ursprünglichen St. Galler Formulars wurde jedoch bei der Übernahme in den Tropar des Fragments erheblich verändert.

Von Ankunft und Aufbruch und ein ‚etwas harter Gang’ durch die Figurenproblematik
Authors: Raab Claus
Published: September 2021

Widerlegt werden Darstellungen, die in Beethovens Werk viele Elemente barocker musikalischer Rhetorik zu finden glauben - so auch im 1. Satz der Klaviersonate op. 81a. Vielmehr kombiniert und schichtet Beethoven in diesem Satz realitätshaltige Signal-Motive, die von Aufbruch künden und zugleich unterschiedlichen Ausdrucksbereichen zugehören. Damit erschließt er dem Topos Abschied mit rein instrumentalen Mitteln die psychische Dimension subjektiv erlittener Trennung, woraus die einzigartige Form des Stückes resultiert. Ganz ähnlich verhält es sich im 4. Satz des Streichquartetts op. 18 Nr. 6 ().
Originalität oder Epigonentum?
Authors: Keym Stefan
Published: September 2021

Julius Reubkes  gilt als getreues Abbild der  h-Moll seines Lehrers Franz Liszt. Tatsächlich unterscheiden sich die beiden Werke deutlich voneinander: sowohl in ihrem Verhältnis zur Sonatenform als auch in Grundstruktur und Abwandlung ihrer Motive sowie der daraus resultierenden Dramaturgie. In der Kombination einer latenten "double-function"-Form mit einem systematisch verwendeten zyklischen Prinzip stellt Reubkes Werk einen originellen Beitrag zur Geschichte der Sonatenform dar, der auf die zyklische Sonate César Francks und die von ihr abgeleitete Theorie Vincent d'Indys vorausweist.

"alte Traum von alten Deutschland"

Similar to national feasts - e.g. the Wartburg Fest 1817 - German music festivals could be understood as symbolic politics: the masses of interpreters and listeners representing the German 'nation', the works, especially symhonies and oratorios, representing the 'greatness' of German culture (shown in texts by Wolfgang Robert Griepenkerl, Eduard Krüger, Robert Schumann). Mendelssohn's , first performed at the Leipzig Gutenberg Fest 1841, then one year later at the Düsseldorf music festival, is discussed as music for national feasts (with its references to the national 'heroes' Gutenberg, Luther, and Beethoven).

Joseph Haydns Skizzen zur  bilden das umfangreichste erhaltene Werkstattmaterial dieses Komponisten zu einem Werk. Die heute in Wien, London und New York aufbewahrten Blätter werden für die von der Autorin vorbereitete Edition der Schöpfung in der Gesamtausgabe  erstmals vollständig diplomatisch übertragen und kommentiert. Die insgesamt 35 Seiten bilden offensichtlich nur einen Teil des ursprünglichen Skizzenkorpus, gleichwohl sind darin geschlossene Arbeitseinheiten zu einzelnen Nummern überliefert, die eine systematische Untersuchung von Haydns Vorgehen beim Skizzieren erlauben. Es zeigt sich, dass Haydn die Seite bei der Skizzierung größerer musikalischer Verläufe nicht schlicht von oben nach unten beschrieb, sondern den Schreibraum entsprechend der musikalischen Form in bestimmte Bereiche gliederte und zugleich zwischen linksbündigen Verlaufskizzen und mittig platzierten Motiv- und Ausschnittsskizzen unterschied. Damit wählte er - entgegen gängiger Forschermeinung - für die Skizzierung von Vokalwerken dieselbe Methode wie für seine Sinfonien und Streichquartette. Die Verteilung der Skizzen auf den zusammengehörigen Blättern belegt zudem, dass er den für sein musikalisches Denken konstitutiven Schreib- und Denkraum einer Doppelseite auch über die Grenzen der Blatteinheiten herstellte, indem er aus zwei verschiedenen Blättern eine Doppelseite als Schreibraum konstruierte.
Nachruf auf den Urtext?

Dass Urtexte nur selten schlechthin originale Texte sind und nur Voraussetzung einer Realisierung, deren Originalitätsanspruch vom Hier und Jetzt des Erklingenden nicht getrennt werden kann, dass es mithin keine mit dem Begriff oft verbundene Ausschließlichkeit gibt, mindert die Verdienste der Bemühungen um sie nicht im Geringsten. Da sich die Ära der Gesamt- beziehungsweise Denkmälerausgaben dem Ende zuneigt, sollten indessen ihre Voraussetzungen und - gegen einen textfixierten Positivismus - der Anteil der ungeschriebenen Selbstverständlichkeiten neu überdacht werden. Dies hülfe auch eine simple Dichotomie von Textaufbereitung und Umsetzung aufzulösen, die darauf angewiesen ist, eine Endgültigkeit der Niederschrift zu unterstellen, die es nie gegeben hat. Herausgeber und Musizierende könnten dergestalt einander näher kommen, diese kritischer lesend, jene sich als Dolmetscher eines allemal mehrdeutigen Textstandes begreifend.
The Castro District in San Francisco as a Contemporary Utopia: “Somewhere over the rainbow”
Authors: Basural Idil
Published: September 2021

In search of a utopia in a real place, in which groups marginalized by society recreate a space, this article offers an analysis of the Castro neighborhood in San Francisco. This neighborhood inhabited by sexual minorities is an example not only of a utopian counter-space, but also of a resident identity based on an urban space, of an international LGBTQ+ community. First, a micro-history of Castro and the imaginary construction of the neighborhood through images, narratives, words, everything visual and discursive will show, the infrapolitics, the invisible structure of this resistance. In a second phase, the promises and conditions of the neighborhood will be examined in order to discuss the accessibility and credibility of this utopia. Based on Foucault’s concept of heterotopias, the principle of "a system of opening and closing" of this utopian space will be questioned through testimonies of the current inhabitants during the San Francisco Pride of 2019. This analysis of the history, structure and semiology of the neighborhood and its relationship to the outside world will allow us to question the possibility of a utopia that is feasible or achieved in today’s world.
The utilization of project risk monitoring and control practices and their relationship with project success in construction projects
Authors: Obondi Kennedy Christopher
Published: September 2021

Risk monitoring and control is often poorly implemented in construction projects because of a failure to monitor and manage identified risks. Construction companies experience significant losses due to project managers' lack of project risk monitoring and control in construction projects. Most studies have concentrated on risk identification, risk assessment, and risk analysis processes while neglecting crucial risk management processes of risk control, risk monitoring, and risk response. The lack of research on these three crucial processes highlights a gap in the literature concerning how these processes can increase the delivery of successful projects. The purpose of this study was to examine whether the utilization of project risk monitoring and control practices was related to project success in construction projects in the United States. An electronic survey instrument was used to collect data from a sample of 50 construction project managers in the Dallas-Fort Worth area in the state of Texas, in the United States. Spearman rho correlation analysis was used to examine the relationship between project risk monitoring and control practices and project success. The results of this study indicated that all project risk monitoring and control practices, including risk reassessment, risk audits, contingency reserves analysis, and risk status meetings, were significantly and positively related to project success in construction projects. One of the recommendations presented in this study was that future research should conduct the same study in developing countries to see if the study’s findings remain the same and generalizable. The study concluded that construction organizations should regularly consider the importance and usage of project risk monitoring and control practices and apply them to improve the success rate of a project.

Los debates sobre el espacio público hacen parte de la singularidad de la convivencia en las ciudades; han estado presentes en el desarrollo de la vida en común, en la evolución de las instituciones que lo resguardan, en las normas que lo regulan, y en los actores que lo construyen. Los conflictos que se generan alrededor del espacio público evidencian su imbricación en la vida cotidiana de los individuos, así como revelan las apuestas estética y política, pero especialmente la apuesta comunicativa, comprometidas en su construcción. Este capítulo ofrece una aproximación al surgimiento, la transformación y las características del espacio público desde una perspectiva histórica y su relación con las dinámicas de crecimiento y expansión de las ciudades contemporáneas.
Una herramienta para la transmisión del mensaje. El storytelling: dimensión creativa del modelo sistémico de la comunicación de gobierno
Authors: Osorio Luna Juan Esteban
Published: September 2021

Contar historias ha sido una constante desde las sociedades más primitivas hasta ahora. Desde las artes en sus nociones más elementales, siempre se ha contado una historia. En su origen más puro no existen agendas asociadas al simple hecho de narrar un acontecimiento; en este caso se trabajará cuándo y cómo proponer los relatos que pueden cumplir un rol activo en la creación de un mensaje con fines políticos o con un objetivo encaminado a cumplir con un papel relevante dentro de una agenda del servicio público. Aquí entonces es tan importante el cómo se cuente como el dónde; no todas las historias necesitan los mismos elementos y los mismos canales a la hora de participar en el juego comunicacional.

Published: September 2021

This paper begins with the debate around the effects that video games have on the upbringing of children and youngsters. After interviewing UABJO high school students, I concluded that not all young people are addicted to video games, and that the time they spend playing them varies greatly, depending on their personal circumstances and age. Several youngsters lost their interest or reduced the time dedicated to video games for various reasons; some due to new interests, friendships or romantic relationships, others because they took on new responsibilities, whether work related or school related, and some more had to do with physical fatigue and boredom.

The SARS-CoV-2 virus is an emerging coronavirus identified in 2019 and is responsible for the disease called COVID-19, which was declared a global pandemic, in 2020 by the World Health Organization (WHO). At the beginning of May 2020, more than 4 million infected people have been confirmed in the world and more than 278 thousand deaths, estimating an economic impact of more than 3 billion dollars. In Mexico, a total of 36,327 positive cases have been confirmed. The impact of this disease is mainly associated with the rapid spread among the human population and the severity of the clinical signs, which, if not treated, can lead to death. Currently, there is no vaccine available to prevent the disease and its control is based on the clinical diagnosis, which must be carried out by a specialist. This diagnosis must be confirmed by laboratory tests, which are of two types, mainly: for the detection of the etiological agent (virological and molecular) and serological (detection of antibodies), both tests must be carried out by institutions approved by the InDRE. The objective of molecular diagnosis (which is the most widely used worldwide) is to identify a fragment of the viral genome, which would indicate that the individual has had exposure and has been infected with SARS-CoV-2. In the case of serological tests, the diagnosis is based on identifying the presence of specific antibodies in serum samples from patients in the convalescent phase, with this test the degree of protection in a population can be evaluated. Both types of tests can be performed in patients with or without symptoms and are of utmost importance for the establishment of prevention and control measures for this pandemic.

Nowadays, schools use many information systems to automate their activities for different stakeholders’ groups – learning management systems, student diary, library systems, digital repositories, financial management and accounting systems, document processing systems, etc. The huge amount of data generated by the users of these systems, led to increased interest in the collection and analysis of data to encourage students to achieve higher results, teachers to provide personalized support and school managers to make data-driven decisions at all levels of school, and stimulates research into the application of Learning Analytics (LA) in schools. The paper presents a LA model and a software prototype of the LA tool designed for the needs of Bulgarian school education from the perspective of different stakeholder groups (students, teachers, class teachers, parents, school managers, inspectors from evaluation agencies), aiming to improve school methods of approaching and analyzing learning data. The tool allows stakeholders to track data for students’ learning or training for different purposes, e.g. monitoring, analysis, forecast, intervention, recommendations, etc., but finally to improve the quality of learning and teaching processes. Research and experiments with the model and the LA tool under consideration are conducted based on the information infrastructure of a typical Bulgarian school.

Correlación entre la resistencia real del concreto y el ensayo no destructivo de esclerometría para muestras de concreto en el departamento de Lambayeque – Perú Autores/as
Authors: Borja Suárez Manuel Alejandro
Published: September 2021

La presente investigación busca encontrar el nivel de correlación entre la resistencia real del concreto (kg/cm2) y el ensayo no destructivo de esclerometría, pero sobre todo determinar el nivel de confianza con el que se deberían aceptar estos resultados. Para esto se evaluaron probetas provenientes de diferentes obras de construcción en la región Lambayeque, indistintamente de sus características de diseño, y antes que sean ensayadas en la prensa de compresión, se les sometió a un examen con esclerómetro digital siguiendo el procedimiento de la NTP 339.181 (2013). Se ensayaron también probetas con diseño controlado para f’c: 175, 210 y 280 kg/cm2 y así comparar si con estas probetas se obtiene una mejor correlación respecto a las probetas provenientes al azar de diferentes obras. Para las muestra analizadas de todas las obras, se encontró una desviación estándar de 45 kg/cm2 (ligeramente alta); y para el caso de concretos de diseño controlado: 13 kg/cm2, con un coeficiente de correlación de r2 = 0.9467 (a los 28 días). Después de procesar todos los datos, se llegó a la conclusión que el ensayo de esclerometría si se puede utilizar para estimar la resistencia a la compresión del concreto pero bajo ciertas condiciones controladas y teniendo en cuenta un margen de error y confiabilidad. Finalmente, se puede concluir que para un nivel de confiabilidad del 95% la resistencia del concreto obtenida con el esclerómetro podría ser estimada con el siguiente rango de precisión: f’c ± 25 kg/cm2.

Introduction: A dental graduate face difficulties in establishing his private setup after graduation. It is essential to introduce entrepreneurial content in undergraduate education. The efficacy of students to launch their practice is known as Entrepreneurial self-efficacy (ESE). This study is aimed to asses ESE in order to implement practice management education.

Methodology: A quantitative study was conducted in Lahore by selecting two dental colleges i.e. UCD, University of Lahore and De'montomorency College of Dentistry, Lahore. A Pre-validated questionnaire was used that contains 17 items. Descriptive statics were performed. Results were analyzed using SPSS version 23

Results: A total of 216 students participated of the dental colleges involved in the study. Mean score of Entrepreneurial Efficacy was 5.1

Discussion: The students of both institutes somewhat agrees to their entrepreneurial self-efficacy. They felt less confidence in their ability to search, plan and marshal to establish their dental setup.

Conclusion: There is a need to introduce entrepreneurial education at the undergraduate level to strengthen the practice management skills of our dental graduates.
Perception of students about Team-based learning (TBL) Problem-based learning (PBL)
Authors: Malik Khizar Ansar
Published: September 2021

Abstract

Background: Medical teaching has evolved over the past few years, from traditional teaching methods such as lectures and practical classes using blackboard, slide projector to more student-centered activities such as self-directed learning, problem based learning (PBL) and team-based learning (TBL) Problem based learning is an integral part of our MBBS curriculum. We introduced TBL to 2nd year MBBS students in Pharmacology department, who are also practicing PBL in 2nd year.

Aim: The aim of the study was to know student’s perception about TBL and PBL.

Methods:  Students were asked to fill the questionnaire regarding each teaching strategy anonymously using both, open and closed ended questions. The data was analyzed by using SPSS version 21.

Results: A total of 120 students filled the questionnaire regarding their perception about TBL, and 94 students filled the questionnaire regarding PBL. Students found the readiness assurance tests and immediate feedback effective for their learning in TBL. While for PBL, students found that different point of views were respected by group members and there is better integration among different disciplines in PBL.

Conclusion: It is the need of the hour to include new strategies in our curriculum which promotes team work and effective communication skills. Both PBL and TBL have advantages of their own and can provide better student learning if incorporated in a medical curriculum, keeping in view the students responses in our study.

“Ese es, hoy, el quehacer del docente: lidiar y vivir con ese tipo de realidad”
Authors: González Angulo Paola Veraliz , Hernández Valdés Pamela María
Published: September 2021

In educational research on the educational situation of El Salvador, the phenomenon of violence has increased signifcantly within public schools. There has been a lack of recognition of how thin affects both the students (which is addressed in very few studies) and the teaching community.
The following essay researches how personal, interpersonal, didactic and institutional dimensions of teaching practice got affected; and the strategies adopted to stay resilient against the impact of the types of violence indicated, as well. In contradiction with this reality, from the cognitive point of view, teachers fail to establish a clear conceptualization of this phenomenon, which has been interpreted as an indication of lack of formal refection and institutional problematization on the subject.

Entre obstáculos de la familia y barreras de la escuela
Authors: Martin Pauline
Published: September 2021

Family involvement in education is considered beneficial, but not all participation improves children´s learning (Gatt & Petreñas, 2012); neither does education policy in El Salvador clearly define expected family participation in schools, much less for difficult contexts of scarce resources, low economic development and insecurity. In the absence of a clear model for family participation in education, the relationship is defined by families’ economic and social limitations and barriers that schools themselves impose. This essay, based on a qualitative case study in two Salvadoran public schools with in-depth interviews, proposes that an adequate model for family participation in school should define separate and shared responsibilities for families and schools, according to each part’s possibilities and needs. In this way, it is possible to respond to the difficulties suffered by families, as well as to the resistance that schools have.
