Published: February 2023

In this work, a kinematic wave-packet model is used to predict installed-jet noise. Large-eddy simulation results of freejets, for Mach numbers 0.4 and 0.9, are used to obtain parameters of wave packets representing large-scale turbulent structures, which were used to provide a model source for the Lighthill analogy used to predict far-field noise spectra. The source amplitude in the model is calibrated using noise measurements for a freejet, and such a wave-packet source is used to predict noise of the same jet in an installed configuration using a tailored Green’s function. Results from the prediction model are compared to installed-jet experimental data for four different observer positions and a large range of frequencies. Overall, the model predicts both directivities and amplitudes similar to the experimental data, with a hump in the generated noise for lower Strouhal numbers and a clear peak near a Strouhal number of 0.2. This low-order model is fast and flexible, and it is expected to be helpful in preliminary aircraft design.

Authors: Liu Chuanzhen , Liu Rongjian , Meng Xufei , Bai Peng
Published: February 2023

Wind-tunnel tests of the double-swept waverider were performed in the off-design states, aiming to analyze its potential advantage in wide-speed performances. The test configurations were generated using the planform-customized waverider design, developed from the osculating-cone method. Then models of double-swept waveriders with the bend and cusp head were fabricated, and compared with a model of a single-swept waverider also built using the same method. A variety of experiments in their on-design and off-design states were performed in the hypersonic wind tunnel FD-07 of our institute, and computational fluid dynamics were employed to simulate flowfields as a supplement. According to the wind-tunnel tests and flow simulations, the aerodynamic forces and longitudinal stability were obtained and analyzed. The aerodynamic performance of the double-swept waverider did not fall significantly when deviating from the design states. The general trend was that, as Mach number increased, the lift-to-drag ratios dropped slightly. The double-swept waverider featured large longitudinal stability margin in hypersonic states, and the change in Mach number had little effect on longitudinal stability. Compared with the single configuration, the double-swept waverider suffered a decrease in lift-to-drag ratio, but showed a significant improvement in longitudinal stability.

Published: February 2023

An assessment of a hybrid Reynolds-averaged Navier–Stokes/large-eddy simulation (HRLES) approach for [Formula: see text] prediction is presented for the NASA High-Lift Common Research Model (CRM-HL). Both free-air and wind tunnel configurations of the CRM-HL are investigated, and the results are compared to the QinetiQ wind tunnel experiments and two other numerical approaches: RANS and wall-modeled LES (WMLES). For the free-air configuration, HRLES is shown to address some of the known shortcomings with RANS and prevent inboard and outboard flow separation particularly in the region of [Formula: see text] and poststall. To achieve these improvements over RANS, LES-appropriate grids and numerical discretizations are required. It was also found that, when applying HRLES to a RANS best practice grid and numerics, the HRLES method significantly underperformed RANS. For the in-tunnel configuration, HRLES showed good agreement with the loads, surface pressure, and oil-flow photographs obtained in the experiment. HRLES was able to improve upon the RANS simulations, which showed a sharp loss of lift at the two highest angles of attack due to large-scale inboard and outboard separation on the wing, by correctly predicting the corner flow separation and showing remarkably close agreement in the flow topologies with the experiment.

Authors: Pritulo Olga A. , Petrov Alexey A.
Published: February 2023

Background. Evaluation of the severity of pathological angiogenesis in patients with psoriasis can be considered as a promising direction for monitoring the activity of the disease and the effectiveness of systemic therapy.
Aims. Evaluation of interconnections between indicators of angiogenesis in the skin and nail bed of psoriasis patients with clinical characteristics of disease course and therapeutic response to the use of methotrexate by a comprehensive study of the morphometric data dynamics of videodermatoscopy in vascular bed of the skin, the severity of blood flow in the dermis and nail bed during ultrasonic power dopplerography and plasma concentrations of vascular endothelial growth factor (VEGF) and endothelin-1 (En-1).
Materials and methods. Work is based on the data analysis from a survey of 82 patients with moderate to severe psoriasis vulgaris in the acute stage, who were first prescribed methotrexate in the form of subcutaneous injections at a dose of 1015 mg per week in combination with folic acid 5 mg per week. Before treatment and three months after the start of methotrexate therapy, all patients underwent videodermatoscopy with dimension of the density and size of dilated skin capillaries, ultrasonography of psoriatic plaques and nail bed of affected nails and measurement of doppler blood flow parameters and concentration of VEGF and En-1 in blood plasma.
Results. A direct correlation was established between the average diameter of dilated skin capillaries (vascular glomeruli), the degree of increased blood flow in the doppler energy study of psoriatic plaques skin area and the plasma concentration of VEGF and En-1 and values of PASI, BSA, sPGA and DLQI indices, as well as the severity of doppler blood flow of the nail bed and NAPSI index (r = 0.210.73). Under the influence of methotrexate treatment, a decrease in diameter and density of vascular glomeruli (16.2 [12.9; 22.5] versus 25.2 [17.1; 33.7] m before treatment (p = 0.002) and (44.6 [31.6; 53.3] versus 53.5 [34.6; 67.4] before treatment (p = 0.04), respectively), the degree of blood flow in area of psoriatic plaques and the concentration of VEGF and En-1 (12.5 [6.7; 26.8] pg/ml versus 19.5 [4.7; 48.1] pg/ml after treatment (p = 0.002) and En-1 (168.2 [97; 319] versus 274.5 [146; 439] pg/ml(p = 0.003), respectively) was observed.
Conclusions. Studied indicators of angiogenesis can be used as additional criteria for assessing the degree of activity and achieving clinical improvement/remission during systemic therapy in patients with moderate and severe psoriasis.

Современные суперкомпьютеры востребованы в самых разных областях науки и техники. Однако их вычислительные ресурсы зачастую используются не в полной мере. Причина нередко кроется в низкой эффективности выполнения пользовательских приложений. Решить возникшую проблему весьма непросто, что связано как с чрезвычайной сложностью строения современных суперкомпьютеров, так и с недостатком теоретических знаний и практического опыта в создании высокоэффективных параллельных приложений у пользователей вычислительных систем. Более того, пользователи зачастую и не знают, что их приложения работают неэффективно. Поэтому важно, чтобы администраторы суперкомпьютеров могли постоянно контролировать и анализировать весь поток выполняющихся приложений. Для этих целей можно использовать различные существующие системы мониторинга и анализа производительности, однако подобные решения в большинстве своем либо не предоставляют достаточный функционал в части изучения производительности, либо не переносимы. В данной работе описывается прототип разрабатываемого программного комплекса, который предоставляет широкие возможности по сбору и автоматическому анализу данных о производительности приложений и при этом является переносимым.

Modern supercomputers are used in various areas of science and technology. However, their computational resources are often not fully utilized. The reason often lies in the low efficiency of user applications. However, it is very difficult to solve this problem, which is due both to the extreme complexity of the structure of modern supercomputers, and to the lack of theoretical knowledge and practical experience in creating highly efficient parallel applications among users of computing systems. Moreover, users are often not even aware that their applications are not working efficiently. Therefore, it is important for supercomputer administrators to be able to constantly monitor and analyze the entire flow of running applications. For these purposes, different existing systems for monitoring and analyzing performance can be used, however, most of such solutions do not provide sufficient functionality for studying performance, or are not portable. This paper describes a prototype of the software package being developed, which provides wide opportunities for collecting and automatically analyzing application performance data and is portable at the same time.

A “short blanket” dilemma for a state-of-the-art neural network potential for water: Reproducing experimental properties or the physics of the underlying many-body interactions?
Authors: Zhai Yaoguang , Caruso Alessandro , Bore Sigbjørn L. , Luo Zhishang , Paesani Francesco
Published: February 2023

Deep neural network (DNN) potentials have recently gained popularity in computer simulations of a wide range of molecular systems, from liquids to materials. In this study, we explore the possibility of combining the computational efficiency of the DeePMD framework and the demonstrated accuracy of the MB-pol data-driven many-body potential to train a DNN potential for large-scale simulations of water across its phase diagram. We find that the DNN potential is able to reliably reproduce the MB-pol results for liquid water but provides a less accurate description of the vapor-liquid equilibrium properties. This shortcoming is traced back to the inability of the DNN potential to correctly represent many-body interactions. An attempt to explicitly include information about many-body effects results in a new DNN potential that exhibits opposite performance, being able to correctly reproduce the MB-pol vapor-liquid equilibrium properties but losing accuracy in the description of the liquid properties. These results suggest that DeePMD-based DNN potentials are not able to correctly "learn" and, consequently, represent many-body interactions, which implies that DNN potentials may have limited ability to predict properties for state points that are not explicitly included in the training process. The computational efficiency of the DeePMD framework can still be exploited to train DNN potentials on data-driven many-body potentials, which can thus enable large-scale, "chemically accurate" simulations of various molecular systems, with the caveat that the target state points must have been adequately sampled by the reference data-driven many-body potential in order to guarantee a faithful representation of the associated properties.

The ability to molecularly engineer materials may be one of the most powerful tools in favor of high performing heterogeneous catalysts. Porous organic polymers stand out as photocatalysts due to their high chemical stability, outstanding optoelectronic properties and their easy and tunable syntheses. In photocatalysis, the insertion of photosensitizing π-extended molecules into a molecularly well-defined donor-acceptor junctions is supposed to increase the cata-lytic activity, but yet remain experimentally underdeveloped. Here, we present a pyrene-based Covalent Triazine Framework (CTF) synthesized through a polycondensation approach, which was designed to contain a molecularly defined pyrene-triazine-bipyridine donor-acceptor-acceptor triad as the repetition unit of the CTF. The CTF is an efficient photocatalyst for hydrogen evolution from water reaching a production rate of 61.5 mmolH2/h/gcat. Moreover, the same CTF can easily be used as porous macroligand for an organometallic Rh complex to efficiently catalyze the carbon dioxide photoreduction into formic acid under visible light.

Authors: Zhuikova Lilia D. , Ananina Olga A. , Sirotina Alina S. , Pikalova Lidia V. , Fokin Vasilii A. , Kononova Galina A.
Published: February 2023

Background. Disability-adjusted life year (DALY) is one of the well-known methods of comprehensive health assessment in the world. The method was developed by the World Bank and the World Health Organization. The DALY units and gross domestic product per capita are used for the assessment of the indirect economic damage from premature death of cancer.
Aim. To estimate the number of years of life lost (DALY method) and economic losses due to death from cervical, uterine and ovarian cancers in the population of the Tomsk region.
Materials and methods. The data of the Tomsk Region Federal State Statistics Service on the mortality of the population of the reporting form C51 Distribution of the dead by sex, age groups and causes of death, data on the sex and age distribution of the population, life expectancy, gross regional product per capita for 2018 of the Tomsk region were used.
Results. In 2018, due to the death from gynecological cancer of the population of the Tomsk Region, 1616 DALY units were lost in absolute numbers. Of these, cervical cancer accounts for 44.3% (717 DALY units), uterine corpus cancer accounts for 24.8% (401 DALY units), ovarian cancer accounts for 30.8% (498 DALY units). At working age (1654 years), the absolute losses amounted to 694 DALYs. The economic damage to the Tomsk Region due to the mortality of the population from cancer of the cervix, uterine body and ovaries in 2018 amounted to 918.2 million rubles. Economic losses as a result of mortality from cancer of the cervix amounted to 407.4 million rubles, from cancer of the ovaries 283.0 million rubles, from cancer of the body of the uterus 227.8 million rubles. The economic damage from gynecological cancers in working age amounted to 394.3 million (42.9% of the total economic damage).
Conclusion. Determining the socio-economic losses associated with mortality from malignant neoplasms of the female genital organs is necessary for the effective use of health care resources, which can be used to justify the need of the population for oncological care.
Signs of Nervous System Sensitization in Female Runners with Chronic Patellofemoral Pain
Authors: Eckenrode Brian J. , Kietrys David M. , Brown Allison , Parrott J. Scott , Noehren Brian
Published: February 2023

Background

Patellofemoral pain (PFP) is a common overuse injury among runners, affecting females at a higher rate than males. PFP can often become chronic, with evidence suggesting it may be linked to both peripheral and central sensitization of the nervous system. Sensitization of the nervous system can be identified through quantitative sensory testing (QST).

Hypothesis/Purpose

The primary objective of this pilot study was to quantify and compare pain sensitivity as identified through QST measures, in active female runners with and without PFP.

Study Design

Cohort Study

Methods

Twenty healthy female runners and 17 female runners with chronic PFP symptoms were enrolled. Subjects completed the Knee injury and Osteoarthritis Outcome Score for Patellofemoral Pain (KOOS-PF), University of Wisconsin Running Injury and Recovery Index (UWRI), and the Brief Pain Inventory (BPI). QST consisted of pressure pain threshold testing to three local and three distant sites to the knee, heat temporal summation, heat pain threshold, and conditioned pain modulation. Data was analyzed utilizing independent t-tests for comparison of between-group data, effect sizes for QST measures (Pearson’s r), and Pearson’s correlation coefficient between pressure pain threshold values at the knee and functional testing.

Results

The PFP group exhibited significantly lower scores on the KOOS-PF (p<0.001), BPI Pain Severity and Interference Scores (p<0.001), and UWRI (p<0.001). Primary hyperalgesia, identified through decreased pressure pain threshold at the knee, was detected in the PFP group at the central patella (p<0.001), lateral patellar retinaculum (p=0.003), and patellar tendon (p=0.006). Secondary hyperalgesia, a sign of central sensitization, was observed via differences in pressure pain threshold testing for the PFP group at the uninvolved knee (p=0.012 to p=0.042), involved extremity remote sites (p=0.001 to p=0.006), and uninvolved extremity remote sites (p=0.013 to p=0.021).

Conclusion

Compared to healthy controls, female runners with chronic PFP symptoms exhibit signs of both peripheral sensitization. Despite actively participating in running, nervous system sensitization may contribute to continued pain in these individuals. For female runners with chronic PFP, physical therapy management may need to include interventions which address signs of central and peripheral sensitization.

Bodyblade™ Training in Athletes with Traumatic Anterior Shoulder Instability
Authors: Pulido Victor , Alvar Brent , Behm David
Published: February 2023

Background

The Bodyblade™ has the potential of enhancing conservative management of Traumatic Anterior Shoulder Instability (TASI).

Purpose

The purpose of this study was to compare three different protocols: Traditional, Bodyblade™, and Mixed (Traditional & Bodyblade™) for shoulder rehabilitation on athletes with TASI.

Study Design

Randomized-controlled longitudinal training study.

Methods

Thirty-seven athletes (age = 19.9±2.0 years) were allocated into Traditional, Bodyblade™, and Mixed (Traditional/Bodyblade™) training groups (3×week for 8-weeks). The traditional group used resistance bands (10-15 repetitions). The Bodyblade™ group transitioned from classic to the pro model (30-60-s repetitions). The mixed group converted from the traditional (weeks 1-4) to the Bodyblade™ (weeks 5-8) protocol. Western Ontario Shoulder Index (WOSI) and the UQYBT were evaluated at baseline, mid-test, post-test, and at a three-month follow-up. A repeated-measures ANOVA design evaluated within and between-group differences.

Results

All three groups significantly (p=0.001, eta2: 0.496) exceeded WOSI baseline scores (at all timepoints) with training (Traditional: 45.6%, 59.4%, and 59.7%, Bodyblade™: 26.6%, 56.5%, and 58.4%, Mixed: 35.9%, 43.3% and 50.4% respectively). Additionally, there was a significant (p=0.001, eta2: 0.607) effect for time with mid-test, post-test and follow-up exceeding baseline scores by 35.2%, 53.2% and 43.7%, respectively. The Traditional and Bodyblade™ groups (p=0.049, eta2: 0.130) exceeded the Mixed group UQYBT at post-test (8.4%) and at three-month follow-up (19.6%). A main effect (p=0.03, eta2: 0.241) for time indicated that WOSI mid-test, post-test and follow-up exceeded the baseline scores by 4.3%, 6.3% and 5.3%.

Conclusions

All three training groups improved their scores on the WOSI. The Traditional and Bodyblade™ groups demonstrated significant improvements in UQYBT inferolateral reach scores at post-test and three-month follow-up compared to the Mixed group. These findings could lend further credibility to the role of the Bodyblade as an early to intermediate rehabilitation tool.

Examining the Peer-Reviewed Published Literature Regarding Low Back Pain in Rowing: A Scoping Review
Authors: Athy Veronica , Hach Sylvia , Anderson Helen , Mason Jesse
Published: February 2023

Background

Low back pain (LBP) is highly prevalent in the rowing population. The body of existing research variously investigates risk factors, prevention, and treatment methods.

Purpose

The purpose of this scoping review was to explore the breadth and depth of the LBP literature in rowing and to identify areas for future research.

Study Design

Scoping review

Methods

PubMed, Ebsco and ScienceDirect were searched from inception to November 1, 2020. Only published, peer-reviewed, primary, and secondary data pertaining to LBP in rowing were included for this study. Arksey and O’Malley’s framework for guided data synthesis was used. Reporting quality of a subsection of the data was assessed using the STROBE tool.

Results

Following the removal of duplicates and abstract screening, a set of 78 studies were included and divided into the following categories: epidemiology, biomechanics, biopsychosocial, and miscellaneous. The incidence and prevalence of LBP in rowers were well mapped. The biomechanical literature covered a wide range of investigations with limited cohesion. Significant risk factors for LBP in rowers included back pain history and prolonged ergometer use.

Conclusion

A lack of consistent definitions within the studies caused fragmentation of the literature. There was good evidence for prolonged ergometer use and history of LBP to constitute risk factors and this may assist future LBP preventative action. Methodological issues such as small sample size and barriers to injury reporting increased heterogeneity and decreased data quality. Further exploration is required to determine the mechanism of LBP in rowers through research with larger samples.
The Effectiveness of Physical Therapy Interventions for Athletes Post-Concussion: A Systematic Review
Authors: Art Kylie , Ridenour Courtney , Durbin Stephanie , Bauer Max , Hassen-Miller Amy
Published: February 2023

Background

Sports-related concussions are the most common cause of head injury in adolescents and young adults. Typical treatment methods for this injury include cognitive and physical rest. Evidence suggests that physical activity and physical therapy interventions can be beneficial to decrease post-concussion symptoms.

Purpose

The aim of this systematic review was to investigate the effectiveness of physical therapy interventions for adolescent and young adult athletes post-concussion.

Study Design

Systematic Review

Methods

The following databases were utilized for the search: PubMed, CINAHL, Proquest, MEDLINE, SPORTDiscus, and SCOPUS. The search strategy focused on athletes, concussions, and physical therapy interventions. Data extraction from each article included: Authors, subjects, gender, mean age, age range, specific sport, acute or chronic concussion, first or recurrent concussion, treatments for intervention and control group, and outcomes measured.

Results

Eight studies met the inclusion criteria. Six of the eight articles scored seven or higher on the PEDro Scale. Physical therapy intervention(s), such as an aerobic intervention or a multimodal approach, show improvements in time to recovery and reduction of post-concussion symptoms in patients who have had a concussion. Physical activity and physical therapy as early as a couple days following injury, is beneficial at decreasing post-concussion symptoms, allows for earlier return to play, and/or shorter days to recovery, and is considered safe for treating post-concussion symptoms.

Conclusion

This systematic review demonstrates that physical therapy interventions including aerobic exercise and multimodal approaches have been found to be beneficial in treating adolescent and young adult athletes post-concussion. Utilizing aerobic or multimodal interventions for this population allows for a quicker symptom recovery and return to sport than traditional treatment of physical and cognitive rest. Future research should investigate the superior intervention for adolescents and young adults with post-concussion syndrome and determine if a single treatment or a multimodal approach is more beneficial.
Effectiveness of Spinal Stabilization Exercises on Dynamic Balance in Adults with Chronic Low Back Pain
Authors: Alshehre Yousef M. , Alkhathami Khalid , Brizzolara Kelli , Weber Mark , Wang-Price Sharon
Published: February 2023

Background

Dynamic balance is a vital aspect of everyday life. It is important to incorporate an exercise program that is useful for maintaining and improving balance in patients with chronic low back pain (CLBP). However, there is a lack of evidence supporting the effectiveness of spinal stabilization exercises (SSEs) on improving dynamic balance.

Purpose

To determine the effectiveness of SSEs on dynamic balance in adults with CLBP.

Study Design

A double-blind randomized clinical trial.

Methods

Forty participants with CLBP were assigned randomly into either an SSE group or a general exercise (GE) group, which consisted of flexibility and range-of-motion exercises. Participants attended a total of four to eight supervised physical therapy (PT) sessions and performed their assigned exercises at home in the first four weeks of the eight-week intervention. In the last four weeks, the participants performed their exercises at home with no supervised PT sessions. Participants’ dynamic balance was measured using the Y-Balance Test (YBT) and the normalized composite scores, Numeric Pain Rating Scale and Modified Oswestry Low Back Pain Disability Questionnaire scores were collected at baseline, two weeks, four weeks, and eight weeks.

Results

A significant difference between groups from two weeks to four weeks (p = 0.002) was found, with the SSE group demonstrating higher YBT composite scores than the GE group. However, there were no significant between-group differences from baseline to two weeks (p =0.098), and from four weeks to eight weeks (p = 0.413).

Conclusions

Supervised SSEs were superior to GEs in improving dynamic balance for the first four weeks after initiating intervention in adults with CLBP. However, GEs appeared to have an effect equivalent to that of SSEs after 8-week intervention.

Published: February 2023

Background: It is essential to study the availability of reproductive health services and the capacities of providers, to provide evidence for improving service quality. Aims: To identify the role of midwives in the provision of reproductive health services and recommend improvements. Methods: A national review of government health resources in the Islamic Republic of Iran was conducted to explore available reproductive health services. Through semi-structured interviews with 30 midwives, information was collected about the compatibility of services with the capacity and scope of the activities of midwives. A panel of 12 experts was assembled to develop a proposed service package. The content analysis method was applied to data analysis and interpretation. Results: The service package developed covered 82 services that midwives can offer at the 8 healthcare facility groups. Although midwives were trained to manage a range of primary and gynaecological care services, certain essential aspects of reproductive health services were not being delivered on the frontline. These include sexually transmitted diseases and human papilloma virus management, diagnosis and treatment of common gynaecological problems, sexual education and counselling, and childbirth services. Midwives were not adequately engaged to provide reproductive health care at the secondary level. Conclusion: There are drawbacks to the current reproductive health service delivery in the Islamic Republic of Iran. The service package designed and proposed in this study aims to strengthen reproductive health care services and planning and better integration of midwife-led programmes.

La historiografía escolar del bachillerato franquista desde la perspectiva del emisor
Authors: Castillejo Cambra Emilio
Published: February 2023

Este artículo establece relaciones entre el mensaje de algunos manuales de Historia del bachillerato franquista, utilizados como fuentes primarias (29 en total) y la posición política de sus autores, fueran castigados (depuración en el escalafón de catedráticos de 1935), o premiados con la convocatoria de oposiciones patrióticas de 1940 que favorecieron a los simpatizantes del golpe de Estado de 1936. Para descubrir esas trayectorias personales se recurre a fuentes secundarias. Si unos autores utilizan el manual de Historia para constatar su fidelidad personal al régimen de Franco; otros, lo utilizan como salvoconducto, para marcar distancias con su pasado masón, republicano de izquierdas, catalanista. Si en autores como José Ramón Castro hay coherencia entre su producción historiográfica profesional y escolar (su fidelidad al régimen es inquebrantable), Jaime Vicens Vives o Antonio Domínguez Ortiz, como autores de manuales representan la cultura oficial (legitiman al régimen); como historiadores profesionales, la denominada cultura establecida, al distanciarse más de él y de sus valores.

Este estudio parte de una formación realizada con profesorado de secundaria que persigue desarrollar competencias históricas y multimodales de forma integrada. En concreto, analiza si el aprendizaje mediante diseño de microdocumentales es un modelo formativo que responde a las necesidades del profesorado y valora si esta formación ha sido transformadora. Se emplea un modelo participativo, de corte cualitativo, en el que participan nueve docentes de cuatro centros de secundaria. Las conclusiones apuntan a que este modelo formativo responde a las necesidades del profesorado y ayuda a implementar una práctica transformadora. Asimismo, contribuye al desarrollo de competencias históricas del profesorado, a su alfabetización multimodal y competencia digital, si bien se observa la necesidad de profundizar en la práctica multimodal y de desarrollar una mayor confianza en su competencia digital.

Authors: López-García Alejandro
Published: February 2023

El siglo XXI ha visto aflorar ultranacionalismos propios del pasado. El neonazismo tiene su razón de ser en el ataque inequívoco contra las minorías, a partir de una ideología racista, xenófoba y excluyente, que tiene como máxima expresión la negación de muchos de los genocidios históricos. Cada vez más partidos de todo el mundo defienden algunas de estas ideas y modelos de pensamiento en sus programas, suavizándolas a la par que van ganando peso en las instituciones e instaurando su discurso e idearios en la ciudadanía. El objetivo de este estudio es analizar la efectividad de una propuesta docente sobre el Holocausto en estudiantes de la etapa de Bachillerato. Para ello, se ha creado un plan de acción que fomenta la indagación y pretende desarrollar una conciencia que promueva el pensamiento ético y critico de estos hechos. Los resultados son muy positivos y confirman que el Holocausto puede y debe trabajarse con documentos históricos, fuentes de internet y otros recursos que potencian el trabajo en grupo y la motivación hacia el conocimiento y la crítica de estos hechos, preservando la memoria histórica.
