Política y moral en la producción de inteligencia. Las clasificaciones y sus sentidos en los archivos de inteligencia en períodos democráticos en Argentina
Authors: Muzzopappa María Eva , Schnyder Maria Celeste
Published: July 2021

Este trabajo analiza documentos del D2 de la policía de Santiago del Estero y de la oficina de inteligencia de una Base Aeronaval en Chubut con el objetivo de identificar sus clasificaciones para la identificación de actores y preguntarse, a partir de allí, respecto del rol de los organismos de información e inteligencia durante los períodos democráticos. Este aspecto, que sigue siendo una de las deudas de la democracia argentina, fue materia de legislación en 2001 con la sanción de la Ley de Inteligencia Nacional 25.520. Sin embargo, el hallazgo de archivos militares y policiales que ocupan a este artículo dan cuenta de la continuidad de la práctica de investigación de antecedentes, reunión de información y producción de inteligencia por razones políticas sobre ciudadanos e instituciones. Esto abre interrogantes en torno a la idea de que el sentido de los documentos responde exclusivamente a las funciones formales del organismo productor. Antes bien, deben ser considerados como artefactos sociales que encarnan y reproducen repertorios culturales políticos de largo aliento, que forman parte de la llamada “baja política” pero que inciden en los procesos, conflictos y decisiones que se despliegan en la dimensión institucional de la política.

La incidencia de la dimensión afectiva en los ciclos de acción en el Movimiento por la Paz con Justicia y Dignidad
Authors:   , Palma López María de los Ángeles
Published: July 2021

El objetivo de este trabajo es interpretar y explicar al Movimiento por la Paz con Justicia y Dignidad (MPJD) desde dos dimensiones interdependientes: desde lo afectivo y desde la estructura de oportunidades y restricciones políticas. Se trata de revelar cómo ciertas estructuras generan una particular dimensión afectiva que impacta tanto en el proceso de movilización como de desmovilización en el Movimiento por la Paz con Justicia y Dignidad; y al mismo tiempo, cómo dicha dimensión pone en cuestión y transforma el statu quo. El estudio se divide en seis capítulos. En el primer capítulo, se presentan las herramientas teóricas y metodológica que retoma la investigación. Se pone a disposición un breve estado del arte de la dimensión afectiva en la teoría de los movimientos sociales. En el capítulo 2, nos concentramos en la incidencia biográfica del líder principal del MPJD, Javier Sicilia. El objetivo es evidenciar la incidencia del liderazgo en la protesta; argumentamos que Sicilia es un dirigente carismático, por ende, emociones y sentimientos cobran un papel fundamental. Tener en claro a dicho personaje nos permite comprender en los siguientes apartados las singularidades del Movimiento. Aludiendo a los poderes en movimiento de Sídney Tarrow, en el capítulo tercero señalamos el marco de injusticia del MPJD. Se muestra el contexto de violencia y criminalización que da lugar a un conjunto de emociones y cómo estas se encauzan hacia la movilización. Se analiza el proceso que permite trasladar un agravio local a uno nacional y sus cimientos simbólicos-políticos. El capítulo 4, reflexiona cómo el desplazamiento en Caravanas propicia una singular interacción que representa físicamente y dota de sentido la indignación la cual denominamos interacción performativa de resistencia. Asimismo, comenzamos a evidenciar los conflictos que llevan a una ruptura entre los miembros. En el quinto capítulo, ponemos énfasis al segundo poder en movimiento, redes y organizaciones. Se expone a los actores —individuales y colectivos—, la organización, los liderazgos y con ello la capacidad de incidencia en la toma de decisiones. Planteamos que los mayores conflictos y agravios al interior son resultado de un conjunto de actores que poseen mayor influencia y del tipo de liderazgo que posee Sicilia. El capítulo sexto, refiere a la incidencia de lo afectivo en las oportunidades y restricciones políticas —tercer poder en movimiento—. Aludimos a la potencialidad de las Caravanas para abrir diálogos con distintas figuras institucionales, entre ellas, el presidente Felipe Calderón; y la evocación de lo emocional como estrategia política. Sin embargo, colocamos en evidencia la utilización de los encuentros y lo afectivo para iniciar un proceso de desmovilización; y las emociones y sentimientos generados.
The role of the formation and destruction of the Hudson Strait glacial ice dam in changes of climate and sea level during the Last Interglacial-Glacial transition
Authors: Johnson Robert G.
Published: July 2021

During the Last interglacial period of constant sea level, large coral reefs formed on the tectonically rising island of Barbados, and a broad lagoon with a small barrier reef formed at the Cane Vale site. The constant sea level was ended by a rapid glaciation, causing a fall of world sea level of 2.4 m, as measured by surveys of features associated with breaking waves on Barbados. The fall began about 120 ka BP, and lasted roughly 400 years, according to a lake pollen record from western Europe. That rapid fall was terminated at a wave-cut step on Barbados and with a quite small reversal in falling sea level. The rise was caused by rapid melting of the marine-based Barents Sea ice dome and other ice masses, due to a restored strong Atlantic Meridional Overturning Circulation (AMOC) flow. The sea level fall then resumed until it was halted at a wave-cut step at a world sea level 12.3 m below the last interglacial level, as recorded at the University of the West Indies site on Barbados. Following the erosion of that second step, a zonal northern North Atlantic circulation prevailed, causing a glacial ice-volume decrease and rise in sea level of 3.8 m. These two sea level fall reversals were caused respectively by the formation and destruction of a Hudson Strait ice dam and the resulting increase and much later decrease in the rate of AMOC flow.

Using proper greenhouse covering materials can provide a suitable environment for plant growth in Saudi Arabia. The effects of three different greenhouse covering materials, clear glass, polycarbonate and diffuse tempered glass were used to evaluate its effect on cucumber productivity, water and energy use efficiency. Results show that either water or light use efficiency was higher in compartments covered with diffused or clear glass than polycarbonate compartment. Inconsequence, fruit yield of cucumber plants/m2 was significantly higher (58%) in clear and diffuse glass greenhouses as opposed to polycarbonate greenhouse. In term of the effect of cultivar or plant density, no significant differences on cucumber yield were found. Using of different covering materials did affect environmental data of greenhouses. Less light was transmitted through polycarbonate cover than clear or diffuse glass. The photosynthesis active radiation (P.A.R.) was 996, 1703, 1690 mol/m2/d, while the electricity consumption was 2.97, 3.44, and 2.88 kWh under polycarbonate, clear glass, and diffuse glass, respectively. Meanwhile, diffuse glass compartment revealed 16% lower of water consumption than other covering materials. In this respect, it could be concluded that using diffuse glass, as a greenhouse cover material, has a strong positive influence on crop productivity under Saudi Arabia climate.

Authors: Olszewska Dorota , Nowaczyk Paweł
Published: July 2021

The results of the investigation proved the gametophytic origin of diploids derived from two-embryonic seeds of pepper C. annuum L. hybrid. During the germination of seeds harvested from the red fruited hybrid (C. annuum L. ATZ × C. annuum L.`Sono`) F1, additional embryos have been found. Four of diploid twins F2 generation were different in their phenotype within the pair and/or from the F1 mother plant. Plants of three pairs: 1A-1B, 2A-2B, 4A-4B were significantly different with regard to the average fruit weight, length and seeds number. Yellow colour of ripe fruit was characteristic for 2A, 3A and 3B plants. In RAPD molecular analysis, twenty-three primers were used and six of them enabled polymorphic products to be obtained in reactions. The results of the analysis confirmed phenotypic differentiation of the twins and their parental forms. The phenotypic and molecular analyses proved that spontaneous diploids from a two-embryonic seeds are ready for the production of genetically stable, sexual progeny.
The destruction of the idyll: Linda Castillo’s and Jodi Picoult’s Amish crime fiction
Authors: Bubíková Šárka
Published: July 2021

The present article discusses recent developments in American crime fiction, namely the so-called Amish mysteries by Linda Castillo and Jodi Picoult. The aim is to show that although Castillo’s and Picoult’s fiction has been termed ethnic crime writing, the way these writers make use of the Amish setting does not serve the primarily educational purpose of raising awareness of a specific ethnic group as was the case with the older generation of ethnic crime writers (such as Tony Hillerman and P.L. Gaus). Employing Bakhtin’s idyllic chronotope (a concept most often critically applied to classic works1 but shown here as a versatile instrument for discussing genre literature as well) as a point of reference, the paper further analyses how the narratives invoke this familiar spatial model and initiate its violation. It is argued that the writers’ narrative strategies serve to achieve the sharpest contrast between the idyllic place of love, family and labour and the hideous crimes committed there, implying that idyllic rurality is either too fragile to be attainable or that its existence is a mere deception.
Political violence and re-victimization inThe Ferryman
Authors: Günenç Mesut
Published: July 2021

Jez Butterworth’s The Ferryman (2017) is a play about the Carney family living in 1980s Ireland during the period of insurgency of the Irish Republican Army (IRA – also known as the Provisional IRA) and its efforts to end British rule in Northern Ireland, a period known as “the Troubles”. This paper focuses on Jez Butterworth, one of the most distinctive voices of the contemporary British theatre scene and a typical representative of the 1990s cultural trend, and his tragedyThe Ferryman, which portrays the struggle and conflicts between Catholic nationalists and Protestant loyalists in Northern Ireland in the last decades of the 20th century. The second major point of the study is that the power of the Irish Republican Party has a heavy impact on the play. The paper also discovers how Sean Carney and other members of his family both embody and apply the story of Eugene Simons and other members of “the Disappeared”. Like other young men, Seamus Carney became a victim during the Troubles and the campaign of political violence. The discovery of his body symbolizes how political violence created the Disappeared and shows that re-victimization and retraumatisation continue in the aftermath of the Troubles.

Published: July 2021

The mechanical properties of the Al-7075 material, which is used in important areas such as automotive, aviation and defense industry, are still being studied by researchers. In this study, the effects of different proportions of Nb additives on the microstructure and mechanical properties of the rapidly solidified Al-7075 alloy was investigated. Rapid solidification processes were carried out with a single roller melt spinner at a disk surface speed of 25 m / s. Microstructure characterization was performed by using a scanning electron microscopy (SEM) and X-ray diffraction. According to the results, the Nb additive significantly increased the micro hardness of the Al-7075 alloy. The microhardness of the sample added with 0.5% by weight of Nb is 0.9 GPa. This value is 3 times higher than the sample without Nb added. The Nb contribution has led to modification of the dimensions and shapes of both α-Al and intermetallic phases. Nb addition reduced the average grain size from 9.1 µm to 2.46 µm.

Published: July 2021

Mechanical properties, wear resistance and impact resistance of a high-alloy chromium cast iron used in the fabrication of grinding balls have been studied. A rank of tempering heat treatments under several temperatures 500°C, 525°C, 550°C and 575°C was performed after austenitized at 1050°C. The Scanning Electron Microscope (SEM) and X-ray Diffraction (XRD) techniques have been used to characterize the microstructures and identify the phases. The wear balls tests were conducted in a rotating drum with a velocity 0.5 r/s. The tribological tests were carried out by evaluated a weight loss as function time. The measurement of the rebound resilience was determined by Charpy impact tests. The results of XRD showed the presence of the martensite, carbides type M7C3 and M2C for all tempering heat treated. The hardness of the sample increased after the tempering and reach nearly 65 HRC at 1050°C. In another hand, it decreased after the tempering treatment it could be explained by precipitation of the carbides type M2C.
Maternal age as a risk factor for cerebral palsy

Published: July 2021

The relationship between maternal age and the occurrence of cerebral palsy is still highly controversial. The aim of the study was to examine the effect of maternal age on the risk of CP development, taking into account all significant risk factors and the division into single, twin, full-term, and pre-term pregnancies. The survey covered 278 children with CP attending selected educational institutions in Poland. The control group consisted of data collected from the medical records of 435 children born at Limanowa county hospital, Poland. The analyses included socio-economic factors, factors related to pregnancy and childbirth, and factors related to the presence of comorbidities and diseases in the child. Constructed logistic regression models were used for statistical analyses. For all age categories included in the estimated models (assessing the effect of demographic factors on the development of CP), only the category of ≤24 years of age (in the group of all children) was significant. It was estimated that in this mother’s age category, the risk of CP is lower (OR 0.6, 95% CI: 0.3–1.0) in comparison to mothers aged 25-29 (p = 0.03). However, estimation with the use of a complex logistic regression model did not show any significant effect of maternal age on the incidence of CP in groups from different pregnancies types.   It became apparent that maternal age is a weak predictor of CP, insignificant in the final logistic regression model. It seems correct to assume that the studies conducted so far, showing a significant effect of maternal age in this respect, may be associated with bias in the estimators used to assess the risk of CP due to the fact that other important risk factors for CP development were not included in the research.
Mobility in Ancient Egypt from the shape and strength of the femurs
Authors: Jesús Herrerín , Margarita Carmenate
Published: July 2021

The aim of the study was to establish the degree of robustness and to infer the level of mobility of a group from ancient Thebes (Middle Egypt). Seventy-one left femurs of adult individuals from the 1st century AD from the tomb of Monthemhat (Luxor) were studied.  Metrical, non-metrical variables, shape and size indices of femur were considered. Stature, body mass and Body Mass Index were calculated. All variables showed higher values in males, the vertical diameter of the femoral head was the variable with the highest sexual dimorphism. Non-metric variables also indicated low robustness, with heterogeneous sex distribution. The robustness, pilastric and platymeric indices indicated that the values were close to those of gracile populations in both sexes. Subtrochanteric size and shape showed no sexual dimorphism. The robustness, size and shape in the middle of the diaphysis suggested a mobility related to a daily occupation without intense physical activity in the legs. The results indicate a profile of low robustness, relative sedentarism with apparent sexual division in daily activities.
Weight status and body composition analysis among Polish boys with autism spectrum disorders
Authors: Trambacz-Oleszak Sylwia
Published: July 2021

Currently, autism spectrum disorders (ASD) are one of the main health care problems in both Poland and in other countries. There are limited studies on the physical growth and body composition among children and adolescents with ASD. Several studies have indicated that the prevalence of unhealthy weight is high among autistic patients. Therefore, the main aim of this study was to assess the prevalence of underweight, overweight and obesity of Polish boys with ASD and to analyse body composition.  

A cross-sectional study was performed on 29 Polish boys aged 3–11 with autism. Anthropometric measurements were taken. Bioelectrical impedance analysis (BIA) was used to evaluate body composition. The percentile values and z-scores for body height, body weight and BMI were calculated. The CDC cut–points were used to determine weight status. Statistical analyses were performed using the Statistical Package for the Social Sciences (SPSS) version 25.  

16.1% autistic boys had z-scores for body weight above two standard deviations, 12.9% had z-scores for body height above two standard deviations and z-scores for BMI above two standard deviations were found in 19.4% of the boys. 13.8% of autistic boys were underweight, 48.3% had healthy weight, 20.7% were overweight, and 17.2% were obese. The mean value of body fat percentage was 18.46%, and 16.1% of the boys with ASD had higher than normal fat tissue.  There is a high prevalence of overweight and obesity among Polish boys with autism.
Correlations Between Respiratory Manifestations And Nutritional Status In Children With Cystic Fibrosis
Authors: Viviana Cuzic , Maria Mihai Cristina , Adriana Bălașa , Larisia Mihai , Cosmin Pantazi Alexandru
Published: July 2021

Background: Cystic fibrosis is a multisystemic genetic disease with autosomal recessive transmission, with progressive clinical evolution and potentially fatal, predominantly found in the Caucasian population. It is characterized by chronic lung disease and malabsorption caused by exocrine pancreatic insufficiency.

Objective: Screening of patients with persistent respiratory disease and malabsorption syndrome to diagnose cystic fibrosis and monitoring the correlation between respiratory manifestations and nutritional status.

Methods: A retrospective study on 8 patients diagnosed with cystic fibrosis, from Department of Pediatrics - Constanta County Emergency Hospital, during the period from 2015 to 2018.

Results: 8 patients were diagnosed by genetic test for 34 mutations and polymorphism of CFTR gene; 2 homozygous patients with ∆F508 mutation (second class of mutations) with severe disease, 2 heterozygous patients with ∆F508 mutation del 2,3; 2 heterozygous patients with ∆F508 and R553X mutations, 1 heterozygous patient with N1303K and 394delTT mutations, 1 heterozygous patient with 2183 AA96 and ∆F508 mutation; 7 out of 8 patients were diagnosed in the first year of life by performing the sweat test, with values higher than 120 mmol/L.

Clinical manifestations at onset were represented by diarrhea and failure to thrive in 4 cases and in 4 cases respiratory manifestations were associated. More than half of cases had less than 6 months of age at first respiratory exacerbation, which was associated with failure to thrive. Analyzing the correlation between genotype and anthropometric indicators, it was observed that the weight was more affected than the height. The analysis between nutritional status and lung function revealed that obstructive respiratory dysfunction with low FEV1 was correlated with nutritional status.

Conclusion: Cystic fibrosis is a severe genetic disease and it is important to diagnose early, because it has been observed that if the diagnosis is established late, the consequences will be severe and lung function will deteriorate earlier.

Authors: Grzegorczyk Anna
Published: July 2021

The aim of the study is to determine the scale and patterns of the social segregation of Aix-Marseille-Provence Metropolis and Marseille, in the light of the socio-spatial processes it is currently undergoing and its influence on social sustainability. In the study, quantitative measures of segregation are confronted with a qualitative interpretation of existing facts gathered during literature analysis and field observations. Population groups most subject to residential segregation are revealed, together with the areas of the greatest concentration of particular population categories. Changes of concentration pattern in the decade 2007–2017 are indicated and the role of gentrification and privatiszation of land, which are all conditioned in Marseille by the city's economic restructuring, liberal housing policy and historical role of the port-industrial system.

Published: July 2021

In this paper, the main objective is to detect changes in the geographical area of Ottawa city in Canada due to floods. Two multi-temporal Synthetic Aperture Radar (SAR) images have been taken to evaluate the un-supervised change detection process. In this process, two ratio operators named as Log-Ratio and Mean-Ratio are used to generate a difference image. Performing image fusion based on DWT by selecting optimum filter coefficients by satisfying the wavelet filter coefficient properties through a novel image fusion technique is named as ADWT. GA, PSO, AntLion Optimization algorithms (ALO) and Hybridized AntLion Algorithm (HALO) have been adapted to perform the ADWT based image fusion. Segmentation has been performed based on fuzzy c-Means clustering to detect changed and unchanged pixels. Finally, the performance of the proposed method will be analysed by comparing the segmented image with the ground truth image in terms of sensitivity, accuracy, specificity, precision, F1-score.

Authors: Başaran Hamit , Karaca Sibel , Koca Timur , Gündoğdu Yasemin Örs
Published: July 2021

Purpose: The aim of this study is to compare the dosimetric results of Helical Tomotherapy (HT) and Multi-field IMRT treatment plans using a Simultaneous Integrated Boost (SIB) technique in the treatment of High-Risk Prostate Cancer (HRPCa) with pelvic nodal radiation.

Methods: Seventeen patients planned with HT and 7,8 and 9 fields IMRT were investigated. All plans were designed with the prescribed dose of 54.0 Gy to the PTVln while simultaneously delivering 74.0 Gy to the PTVPS in 30 fractions. Dosimetric data of PTV and OARs were compared.

Results: HT gives a better CI and HI of PTVPS compared to multi-field IMRT plans. HT plans significantly improved target coverage (HT:0.95 vs multi-field IMRT: 0.52, 0.49 and 0.49 respectively, p < 0.001). Bladder mean dose(Gy) (HT: 45.6 vs multi-field IMRT: 53.6, 53.3 and 52.7 respectively, p = 0.004) and D66%(Gy) dose (HT: 35.3 vs multi-field IMRT: 46.7, 47.0 and 44.9 respectively, p = 0.006) were lower in HT. But multi-field IMRT plans significantly reduced the rectum volume receiving more than 75 Gy; (HT V75% (%) 2.7 vs multi-field IMRT 0.8, 1.4 and 0.9 respectively, p = 0.008). HT provided better sparing of the right and left femoral head receiving a mean dose. The penile bulb and small bowel doses were the highest in HT compared with multi-field IMRT.

Conclusions: HT achieved better dose distribution to target compared to multi-field IMRT. This study suggests HT as a reasonable option for the treatment of HRPCa patients.
Urban Theatricalities, A Communicational Claim. Reading of the Scenic Performances of the City of Jijel (Algeria)
Authors: Khelfallah Sheherazad , Farhi Abdallah
Published: July 2021

This article aims to analyse and interpret the structures responsible for the urban theatricality with deep claims of the city of Jijel (Algeria). It is through scenic readings of public space that this study explores the latent expressions of users as stage directors. This will be done mainly with observation supported by research interviews that combine qualitative and quantitative studies. The urban theatricalities studied in this paper are those unconscious, spontaneous and continual experiences that the actors of the urban scene use to make an urban spectacle. It is about the spectacle of daily life and scenic transcriptions of experiences. The results of this scenic reading of urban script allow us to understand the hidden expressions responsible for communicational theatrical structures.
Natural Resources, Urbanisation, Economic Growth and the Ecological Footprint in South Africa: The Moderating Role of Human Capital
Authors: Nathaniel Solomon Prince
Published: July 2021

South Africa is the largest emitter of CO2 and arguably the most developed and urbanised country in Africa. The country currently harbours an ecological deficit territory which could be the outcome of economic expansion, urban explosion, unsustainable resource exploration and a low level of human development. After all, environmental distortions are mainly the outcome of human activities. This study is a maiden attempt to examine the linkage between urbanisation, human capital, natural resources (NR) and the ecological footprint (EF) in South Africa. Unlike previous studies, this study employs positivist and relevant environmental indicators that accommodate built-up land, forest land, carbon footprint, ocean, grazing land and cropland. Findings from the long-run results suggest that urbanisation, economic growth and NR increase the EF, whereas human capital ensures environmental sustainability. The interaction between urbanisation and human capital mitigates environmental degradation by reducing the EF. The canonical cointegrating regression (CCR), dynamic ordinary least squares (DOLS) and the fully modified ordinary least squares (FMOLS) results further confirm the nature of the relationships and linkages existing with respect to NR, urbanisation, economic growth and the EF. A bidirectional causality exists between human capital, economic growth and the EF. Policies related to NR and urban sustainability, the limitations of the study, as well as possible directions for future research are discussed.

The purpose of this study was to identify the willingness of farmers to pay for small-scale irrigation (SSI) and its determinants. Additionally, this study analysed the physical water availability in the study area using 16 years’ (2004–2019) historical data of streamflow, rainfall and forest cover change. A structured questionnaire was used to collect the data from 100 farmers. A contingent valuation method was employed to elicit farmers’ willingness to pay (WTP) for irrigation water. The results show that the average WTP of farmers is US$ 215.84/ha/year. It accounts for 20% of farm revenue and is almost 20 times the water fee in large-scale irrigation systems. The study area experienced significant deforestation in the last two decades suffering a decrease of 11.72% of forest cover. It decreases the amount of stored rainwater and decreases the streamflow causing water scarcity during the dry season. Farm size, farmer income, distance to a small dam and usage of water-pump are the significant determinants. The results indicate that water scarcity caused by poor infrastructure increases the economic value of water in a SSI system.

Building the Engineering Mindset: Developing Sustainable Leadership and Management Competencies in First Year Engineering
Authors: Jamieson Marnie V. , Donald John R.
Published: July 2021

The broad inclusion of sustainable engineering leadership and management concepts are increasinglyrecognized as necessary to ensure the relevance of an engineering education in a rapidly shifting world.Engineering leadership and management are integral to the engineering mindset and necessary to addressthe complex engineering problems faced by society. Examples of these complex problems can be seen in theUN Sustainable Development Goals (SDGs) adopted by all UN member states, including Canada, in 2015[1]. The Canadian Engineering Accreditation Board (CEAB) identifies the need for strong non-technicalskills with a majority of the Graduate Attributes focusing on non-technical skills such as communication,teamwork, ethics and lifelong learning [2]. The UN SDGs are well aligned with the CEAB GraduateAttributes [3] and could be very effectively operationalized in engineering programs through the use of asustainable engineering leadership and management model.
TRANSITIONING TO ONLINE TEACHING IN AN UNDERGRADUATE APPLIED ENGINEERING COURSE
Authors: Mortazavi Pedram , Zhong Chiyun , Christopoulos Constantin
Published: July 2021

The online teaching framework presented in this paper was developed for a third-year engineering design course at the University of Toronto, with more than 100 students located in 8 different time zones. The study was inspired by the pressing challenge faced by educators around the world in 2020 to fully transition to online teaching in a limited time, due to the COVID-19 pandemic.  Different facets of the course were restructured to enhance the learning experience of students, overcome the challenges associated with online instruction, and implement active learning techniques in the course whenever possible. This initiative included the development of interactive course notes and a course map, with links to videos, 3D models, asynchronous lectures, and short video explanations.  Several online paltforms were used in the framework, which are discussed in detail.  The proposed framework provided an alternative to achieve the desired teaching outcomes in an online teaching environment for an engineering design course which had always been taught in-person prior to the year 2020. Despite the inherent challenges of this transition to online teaching, this format allowed for active learning activities in the course, promoting learner-centered teaching, and strengthening the students’ collaborative skills. Elements of the framework and the methodology outlined in this paper could be useful for other engineering courses attempting an effective transition to online instruction.
DEVELOPMENT OF LARGE SCALE STEM PROBLEM DATABASES FOR STUDENT LEARNING AND ASSESSMENT TOOLS
Authors: Davis J. A. , Lorimer S.A.
Published: July 2021

Problem databases in STEM courses are used in tools for the development of student learning andfinal assessment. In addition, large problem databases are used to develop models for automatic assessment and feedback of students’ work. However, the availability of large, open source, problem databases for specificcourses is limited, and in-house development of a wide variety of problems can take years. In this paper, theframework for a problem database in STEM courses was created using semantic analysis of sentence structure and composition. Problem statements were analyzed to determine the key grammatical constructs that are used in commonly posed problems. Based on this analysis, software was developed to create large problemdatabases which allow for simple extension to other courses. Using a first-year mechanics course this softwarewas populated with a few generalized question and sentence structures to create a large problem database.

Authors: Torvi David , Noble Scott , Bitner Doug , Fauchoux Melanie , Peace Rob , Retzlaff Rick , Oguocha Ike , Reitenbach Hayden
Published: July 2021

Since the mid-1980’s, the mechanical engineering program at the University of Saskatchewan has included three core third and fourth-year lab courses, each of which consists of 9-10 individual labs. In 2015 a task group was set up to review these courses, including deliverables, scheduling and links to material in corecourses. Since this time, the task group has taken on the major responsibility for continuous improvement of the lab program, including reviewing student evaluations, making changes to labs, and recommending equipment purchases.  The task group has also been responsible for a major redesign of the lab program, which will improve delivery and scheduling of labs, alignment with core courses, workload of students, and experience gained by graduate teaching assistants. Smaller apparatus have been designed and built in-house to allow students to gain additional hands-on experience. Labs have been designed to build on one another in order to systematically improve students’ general laboratory skills, including the use of data acquisition systems and experimental design. This new approach was used for the first time in ME 328 in 2019-20.  This paper will focus primarily on the role of the task group in continuous improvement, and the lab program redesign.  The new ME 328 course is described, along with lessons learned from the first offering. The task group’s role in moving to remote labs during COVID-19 is also discussed.
STUDENTS AS PARTNERS PEDAGOGICAL APPROACH IN ENGINEERING EDUCATION: A CASE STUDY AND MULTIPLE PERSPECTIVE REFLECTION
Authors: Chan Adrian D. C. , Colley Laura , Dempsey Ryan
Published: July 2021

Instructors engaging students as partners in curriculum development is a growing pedagogical approach. This can promote a two-way conversation between instructors and students and jointly benefit both sides of the partnership. This paper will take the form of a case study centered on implementation of the Students asPartners Program (SaPP) for two compulsory biomedical engineering courses at Carleton University. Reflections on student partnership and its effects will be considered from multiple perspectives: from the instructor, from the SaPP student, and from a student who took one of the courses. Generalized observations will be presented, as well as reflections that may be applicable to the engineering academic community at large.
