Dynamic semantic ontology generation: a proposal for social robots
Authors: Sevilla Salcedo Javier , Quispe-Flores M. A. , Carrasco-Martínez Sara , González-Jiménez Jaime , Castillo José Carlos , Castro-González Álvaro , Malfaz María , Salichs Miguel Ángel
Published: September 2021

During a human-robot interaction by dialogue/voice, the robot cannot extract semantic meaning from the words used, limiting the intervention itself. Semantic knowledge could be a solution by structuring information according to its meaning and its semantic associations. Applied to social robotics, it could lead to a natural and fluid human-robot interaction. Ontologies are useful representations of semantic knowledge, as they capture the relationships between objects and entities. This paper presents new ideas for ontology generation using already generated ontologies as feedback in an iterative way to do it dynamically. This paper also collects and describes the concepts applied in the proposed methodology and discusses the challenges to be overcome.
Perceived Security and Trust in Electronic Payment Systems: How They Affect the Decision to Use EPS During the COVID-19 Pandemic
Authors: Primadineska Rasistia Wisandianing , Jannah Syayyidah Maftuhatul
Published: September 2021

Research aims: This study is intended to determine the influence of perceived security and trust on the decision to use digital payment systems during the COVID-19 pandemic.Design/Methodology/Approach: The type of data used in this study was primary data, which was collected using an online survey. Sample used in this study determined by purposive sampling method. The information collected was handled and analyzed using SEM-PLS.Research findings: This study shows the results that the presence of technical protection explicitly affects the perception of security and trust significantly. In addition, security also greatly affects an individual's confidence in the use of digital payment systems. However, of the various findings made in this study, trust is the only one that influences the choice in using EPS.Theoretical contribution/Originality: During this pandemic Covid-19, limited studies talk about consumers’ perceptions instead of technical protection of digital payment in detail. Meanwhile, consumers' security is the thing that needs to be studied further to create a comprehensive study result.Practitioner/Policy implication: Results of this study give some implications for the EPS providers to complete and develop a secure EPS system for users, especially in this pandemic era when the EPS users increase and people’s mobility is restricted in some areas.Research limitation/Implication: The implication of this research is to emphasize the importance of one's knowledge regarding risks when using an electronic payment system. It is because the use of EPS in the pandemic era is unavoidable. Therefore, not only providers must improve their security systems, but users must also be aware of the EPS risks and security. Nevertheless, the limitation of this study is that it only used samples in Indonesia; maybe the results will be different when applied in other countries with better EPS security systems.
Propriedades da cana-de-açúcar e qualidade da bebida brasileira caldo de cana
Authors: Santos João Víctor De Andrade dos , Silva Geilson Rodrigues da , Gandra Lucas Pereira , Kwiatkowski Angela , Gomes Aline Dos Santos Garcia
Published: September 2021

Além de ser matéria-prima para o açúcar, a cana é considerada uma alternativa para o setor de biocombustíveis e outras bioenergias são produzidas a partir da queima do seu bagaço. A cana também é utilizada in natura sob a forma de forragem, e também como alimentação animal ou como matéria-prima para a fabricação de cachaça, caldo de cana, rapadura e melado. O caldo de cana é uma bebida obtida pela extração do caldo pela moagem (esmagamento) do colmo da cana-de-açúcar. O alto teor de sacarose em sua composição química, confere ao colmo o sabor doce devido. A cana-de-açúcar é uma cultura semiperene de grande versatilidade, sendo matéria-prima do açúcar (sacarose), da cachaça, do álcool e da rapadura. Como há poucos trabalhos na literatura científica que destacam a cana-de-açúcar para produção da bebida caldo de cana, também conhecida como garapa, este trabalho visa apresentar alguns aspectos da cultura e da bebida, como características químicas e conservação. A conservação é um aspecto importante a ser analisado, visto que o caldo de cana tem em sua composição alto teor de sacarose, o que pode promover elevado índice de degradação dos componentes da bebida e reduzir sua qualidade tão apreciada pelos brasileiros. Embora seja uma bebida popular, o caldo de cana ainda carece de condições de higiene mais apropriadas para a sua comercialização. Sendo assim, este trabalho destaca que ainda são necessárias contribuições científicas para o fortalecimento comercial da bebida.
Quantificação de descargas parciais em geradores usando modelo matemático baseado na teoria de campo
Authors: Leite Reinaldo Corrêa
Published: September 2021

Este trabalho desenvolve um modelo para quantificar o nível de descargas parciais (DP) em cavidades ocluídas em sistemas de isolação de geradores. O modelo baseia-se na teoria de campo e usa o Método dos Elementos Finitos (MEF) para resolver as equações de campo. A simulação desenvolve-se em dois passos: no primeiro passo simula-se a situação anterior à descarga parcial, em que não existem cargas espaciais no interior da cavidade, pela resolução das equações de Laplace. Já o segundo passo simula a situação logo após a ocorrência da DP, resolvendo-se as equações de Poisson, simulando a existência das cargas espaciais criadas durante o tempo de descarga. As simulações indicam uma diferença de 2,14% entre os níveis de DP medido e calculado para uma delaminação na isolação de uma barra estatórica. Com base nesse resultado, o modelo é capaz de estimar o nível de DP para defeitos localizados no sistema de isolação de estatores de hidrogeradores.

Listeria monocytogenes es un patógeno ubicuo intracelular, causante de la Listeriosis, la cual se considera una enfermedad transmitida por alimentos (ETA). En la actualidad existe una creciente demanda de consumidores de productos alimenticios tratados mínimamente que pueden favorecer la proliferación de este microorganismo. Es necesario contar con programas de vigilancia que incluyan métodos fiables para la detección de este patógeno en casos de brotes epidémicos. Esta revisión bibliográfica compara las ventajas y desventajas de las técnicas fenotípicas y genotípicas utilizadas en la determinación de L. monocytogenes con el fin de definir la más adecuada que permita obtener resultados confiables y en el menor tiempo posible. Se realizó una búsqueda bibliográfica en bases de datos como Pubmed, Science Direct, Proquest y Ovid, en inglés y español, utilizando los siguientes descriptores: L. monocytogenes, molecular typing, diagnosis, PCR y bacterial typing techniques. Estos se combinaron de diferentes maneras para, finalmente, recopilar setenta artículos que cumplieron con los criterios de selección propuestos. Como resultado se presentan las técnicas de diagnóstico fenotípico y genotípico que representan una opción útil para el aislamiento e identificación de este patógeno a partir de diferentes orígenes. Las técnicas revisadas permiten la diferenciación entre especies patógenas y no patógenas, así como de serotipos y genotipos con base en la implementación de procedimientos cuya fundamentación puede diferir, pero que igualmente pueden ser complementarias.

Published: September 2021

A comparative analysis of ash and slag waste (ASW) of six deposits, differing in quantitative chemical and phase composition, granulometry, melting temperature and other properties, is presented, and the production of a material promising for the construction industry is proposed – aggloporite, the production technology of which practically does not depend on the composition and properties of TPP ash. Aggloporite can also be used in road construction to form side slopes. The proposed method of recovery of large volumes of ash and slag waste accumulated at a number of power plants opens up opportunities to improve the environmental situation in the areas located in the vicinity of coal power plants, free up significant land areas occupied by ash and slag waste storage facilities, and reduce the harmful effect of waste on soil, water and air.

Authors: Chugainova A.A. , Rudakova L.V.
Published: September 2021

The data on the dynamics of e-waste generation in different countries are presented and modern methods of handling this type of waste are analyzed. The characteristics of the component composition of electronic waste are given. The problem of neutralization and disposal of mobile phone screens has been studied. An analysis of possible methods for extracting metals from electronic waste has been carried out, which has shown the promise of a biotechnological method based on the ability of the biomass of microscopic algae to selectively, under certain conditions, sorbs metals. Based on the analysis of the research results of domestic and foreign scientists presented in the literature the process of extracting indium from the screens of mobile phones using microscopic algae was simulated under laboratory conditions. When justifying the choice of indium as an extractable metal, two criteria were used: limited distribution in the earth's crust and the difficulty of obtaining from natural ores, as well as demand in various industries. In experimental studies, the parameters of the effective extraction of indium by the biosorption method have been determined.

Published: September 2021

The results of assessing the state of surface water bodies located in the zone of influence of the closed landfill of industrial and household waste "Shcherbinka" (Domodedovsky district of the Moscow region) are presented. The toxicity of river and waste waters of the landfill was determined by the biological effect on two species of higher plants – oats sowing (Avena sativa) and watercress (Lepidium sativum). As test reactions, the length of the roots of oat seedlings, the germination and length of seedlings of watercress seeds were used. It was found that wastewater from the surface and body of the landfill has a pronounced phytotoxic effect (52–98 %), which manifests itself in the suppression of all the assessed indicators. The high toxicity of river water in the place of discharge of leachate from the waste disposal facility was shown (the phytoeffect value reaches 37 %). As you move away from the source of pollution (when moving downstream of the river), mixing the leachate with river water reduces the concentration of chemicals in the waters to levels that are safe for plants. The values of the estimated indicators obtained during biotesting of river waters at a distance from the landfill are comparable with the control ones. The experiment revealed a similar sensitivity to toxicants of two plants selected as test objects.

Published: September 2021

The evaluation issues on the aggregate’s extraction on the ecosystem of bodies of water has been considered. The dredgers' impact of various capacities on bodies of water of different capacities have been compared, as well as on food supply change of bodies of water for benthos eater. The research findings have showed the dragger's impact of a higher capacity is bigger on a large body of water than this of a lower capacity on a small body of water. The impact manifests itself in decreasing the number and biomass of macrozoobenthos in the area used for the oil and lubricants extraction and the downstream flow. It has been found that the complete destruction of macrozoobenthos at the site of hydraulic engineering activities has not been detected either in small rivers or in large reservoirs.

Published: September 2021

The analysis of the main approaches to the assessment of environmental safety is presented. The requirements for environmental safety measurement are justified. The relationship between safety and development, safety and danger are revealed. The approach to the environmental safety methodology is proposed. The goals of environmental safety are justified. The article analyzes life expectancy as the indicator of environmental safety and its dependence on other priorities of the state development, such as the cost of childbirth and raising children, support for pregnant and nursing mothers, care for pensioners (the size of pensions, their indexation, retirement age), the cost of ensuring industrial and transport safety, etc. The indicators that determine the quality (state) of the natural environment as maximum permissible environmental loads and the degree of proximity of the ecosystem state to the border of its stability are considered in the article. The possibility and advantages of using the assessment of the photosynthetic organisms (photosynthetics) state as the indicator of environmental safety are substantiated. The possibility of using the other integral biota state indicators to assess environmental safety is shown in the article.
Palmer Amaranth (Amaranthaceae) and At-Plant Insecticide Impacts on Tarnished Plant Bug (Hemiptera: Miridae) and Injury to Seedling Cotton Terminals
Authors: Randell Taylor M. , Roberts Phillip M. , Culpepper A. Stanley
Published: September 2021

The direct effect of Palmer amaranth, Amaranthus palmeri Watson, on cotton growth and development is well documented, but its indirect effect through harboring feeding insects is less understood. Palmer amaranth emerged with cotton and remaining in the field for 30 days increased tarnished plant bug, Lygus lineolaris (Palisot de Beauvois), populations compared with a weed-free system. Weedy systems noted up to 49% more damaged terminals than weed-free systems, with cotton yield decreasing as damaged terminals increased at one of two locations. Thrips (Thysanoptera: Thripidae) populations were effectively controlled with Aeris® (Bayer, St. Louis, MO) seed treatment (imidacloprid + thiodicarb at 0.375 mg active ingredient per seed), but there was no correlation between thrips infestations and increasing damaged cotton terminals. However, Aeris seed treatment significantly reduced the occurrence of damaged cotton terminals. In a second experiment, Palmer amaranth infesting an area adjacent to a weed-free cotton field had maximum damaged terminals of 51% on the cotton row proximal to the weedy area, with the distal cotton row (44 m away) having 8% terminal damage. Cotton yield significantly decreased as damaged terminals increased. A final bioassay experiment further evaluated the influence of seed treatment on tarnished plant bug feeding impacting cotton seedlings. With Aeris seed treatment, tarnished plant bug mortality was 97%, compared with 37% for nontreated seed. Results suggest tarnished plant bug infestations increased where Palmer amaranth was present in cotton fields. Additionally, greater Palmer amaranth infestations led to an increase in damaged cotton terminals and lower yields.

Egg parasitoids are the most used natural enemies in biological control of Spodoptera frugiperda (J.E. Smith), a pest of gramineous plants native to the Americas that recently invaded Africa and some countries of Asia. Although Trichogramma pretiosum (Riley) is one of the main species used against this pest, there are other species with equal or greater parasitism potential. The objective of this work was to compare, in laboratory and in field cages, the parasitism of Telenomus remus Nixon, Trichogramma atopovirilia (Oatman and Platner), and T. pretiosum on S. frugiperda eggs. Telenomus remus and T. atopovirilia reached the highest percentages of parasitism in laboratory (>70%) which did not differ statistically from each other. Trichogramma pretiosum had the lowest percentage of parasitism (29%) of the three. In the field cage assays, Te. remus parasitized 30% of the S. frugiperda egg masses, and T. pretiosum parasitized about 7.5% of the egg masses. These results underscore the importance of adequate selection of egg parasitoids for their use in biological control programs by augmentation against S. frugiperda.

Published: September 2021

Background: The aim of this study was to compare the epochs before and after the revision of the transfusion guideline, and determine their effects on transfusion rates and short-term outcomes in preterm infants.
Materials and Methods: This retrospective study was conducted to investigate the effect of the new transfusion guideline. Infants who were born <32 weeks of gestation and received red blood cell (RBC) transfusion in their first 6-weeks of life were divided into two epochs according to adopting the new transfusion guideline. The demographic and clinical data of the patients were compared between these two periods.
Results: Fifty-six infants were included (Period 1, n=22; Period, n=34). The number of transfusions, total and cumulative volume of the transfusions were similar in the two periods. There was an inverse relationship between the gestational age and the number of transfusions in both periods (r=-0.575, p=0.005, and r=-0.494, p=0.003), and there was an inverse relationship between the birth weight and the number of transfusions in period 2 (r=-0.423, p=0.013). The ratio of total phlebotomy volume to estimated total blood volume was higher in period 2 (p=0.029). There was a direct relationship between the phlebotomy loss and volume of RBC transfused in period 2 (r=0.487, p=0.003). The incidence of morbidities was similar in the two periods.
Conclusion: Changing only the transfusion protocol did not decrease the transfusion number. Although transfusion guidelines were adopted rigorously, it seems to be impossible to reduce RBC transfusion rates unless anemia prevention strategies were also in place.

Published: September 2021

Methemoglobinemia is a rare autosomal recessive genetic disease caused by disruptive mutations in the CYB5R3 gene (MIM: 250800). Herein, a novel mutation is reported in an Iranian patient affected with methemoglobinemia type II. In this case study, the patient is precisely described according to the thoroughly carried-out examinations and workups. In so doing, the peripheral blood sample was collected to evaluate the methemoglobin level and NADH-CYB5R3 activity test. Moreover, whole-exome sequencing (WES) was recruited to identify the mutation leading to this disorder. Subsequently, Sanger sequencing was employed to confirm the detected mutation. Magnetic Resonance Imaging was also performed to explore the structure of the brain. As identified by the blood test, the methemoglobin level increased up to 25%, and the NADH-CYB5R3 enzyme activity showed to be 13.8 IU/g of Hb. A novel homozygous mutation in CYB5R3 (NM_001171661: g.23435C>T, c.181C>T, p.R61X, rs1210302322) was identified as the cause of the Methemoglobinemia type II in the proband. This nonsense mutation alters arginine to the stop codon at position 61 of protein in the FAD-binding domain that results in a truncated protein. The MRI revealed brain atrophy and corpus calusom hypoplasticity. It was established that this variation can lead to Methemoglobinemia. The proband demonstrates Methemoglobinemia type II phenotype such as cyanosis, severe mental retardation, microcephaly, as well as developmental delay. The brain MRI revealed brain atrophy and corpus calusom hypoplasticity. The cyanosis symptom is managed by daily ascorbic acid uptake.

Published: September 2021

The best way to prevent unplanned downtime of production machines is certainly adherence to the principles of preventive maintenance. In case of extremely difficult working conditions and the contaminated working environment of the machine, a major maintenance intervention is required. This involves not only the replacement of worn parts, but also design changes, the use of other materials or shapes, such as hydraulic cylinder seals. Such a major intervention often also presents a major logistical and organizational challenge. As such an example, the paper presents the reconstruction of an older special press for the production of molds for casting and is still of key importance for the production of the company. The challenge was to renovate a special hydraulic block with 63 hydraulic rollers mounted in a 9 x 7 matrix, which, in addition to the appropriate force for sand compaction in all molds, must also ensure flawless compression parallelism.

Published: September 2021

The hydraulic cylinder is dimensioned based on a static or dynamic criterion, assuming the desired operating pressure. The paper further analyzes the dimensioning of cylinders according to different load categories. The sizing of the hydraulic cylinder affects the choice of control algorithm parameters but also the stability of the system. How the cylinder dimension and the gain of the distributor affect the choice of the integral constant in the control algorithm in the case when we have the PI control law is especially considered. Then we have by definition an unsTable system 1 / s2 to which we provide stability through feedback.

Background: The linear type traits are the one of important tools for selection of milch cattle. The lifespan of cattle mostly depends on these linear type traits particularly feet and udder related traits. So it is necessary to measure the linear type traits and effect on longevity of Sahiwal cattle. Methods: The experiment was conducted on 86 Sahiwal cattle maintained in Bull mother experimental farm and government cattle breeding farm, Anjora, Durg (C.G.). The linear type traits in Sahiwal cattle were measured as per the recommendation of International committee for animal recording (ICAR). Result: The different linear type traits were studied the average value of stature 125.39±0.534, Chest width 27±0.49, rump angle 12.75±0.97, rump width 17.32±0.29, rear leg set (side view) 146.03°±0.91, rear leg set (rear view) -3.74±0.15, udder depth 18.97±0.43, udder cleft 2.77±0.95, rear udder height 24.06±0.45, fore udder attachment 130.50±1.75° and front teat position 3.61±0.13 cm. these linear type traits mainly affects the longevity and survivability of Sahiwal herds. The most of the traits were found to be intermediate type it leads to increase the longevity and fewer reproductive problems in the Sahiwal herds.

El trabajo presenta un acercamiento sobre el estado de situación del ocio y el turismo sostenible en Costa Rica, a partir de una serie de categorías de análisis tales como: sitios históricos y patrimoniales, actividades culturales programadas, espacios acuáticos, sitios de atracción cultural, sitios de atracción natural, servicios turísticos o actividades de entretenimiento, recreación y esparcimiento, actividades de aventura, sitios de educación natural y cultural y rescate de animales silvestres. El propósito es disponer de un estado de situación que oriente el desarrollo de investigaciones y propicie gestiones oportunas en aspectos diversos como política pública, planes locales o emprendimientos afines a la búsqueda de reducir la brecha que eventualmente se observa en el cumplimiento del derecho universal al ocio, la recreación y al turismo. El marco teórico orienta hacia la reflexión, sobre la actividad turística, la sostenibilidad, el turismo social, los destinos y lo que implica esta actividad económica en el desarrollo económico local. La metodología utilizada se centró en el análisis bibliográfico y en trabajo de campo, el cual permitió un acercamiento particular al objeto de estudio. En la conclusión, se destaca que el turismo supone acceso a gran cantidad de personas, quienes en principio deben tener derecho al ocio, por lo tanto, es una actividad para el disfrute de las personas de diferentes extractos sociales. Sin embargo, la accesibilidad a los diferentes sitios se da en función de una marcada diferencia del poder adquisitivo de las personas.
Reverberações simbólicas no Google Trends: uma análise do imaginário na internet
Authors: Contrera Malena Segura , Torres Leonardo Souza
Published: September 2021

O texto propõe uma análise dos termos mais pesquisados da plataforma Google nos últimos dez anos, visando mapear, pela ferramenta Google Trends, a irrupção de conteúdos do imaginário na comunicação em rede. Buscou-se uma adaptação da proposta de Mitodologia de Gilbert Durand para se identificar o mito que irrompe na mídia eletrônica. A partir desses dados levantados, propôs-se uma reflexão sobre o Arquétipo de Tânatos e seus desdobramentos simbólicos para a sociedade mediática, questionando acerca do papel dos meios de comunicação e das práticas comunicativas nesse cenário cultural que elege a morte como seu símbolo diretor. Recorreu-se às contribuições da Teoria do Imaginário, Teoria da Comunicação e da Mídia, estabelecendo cruzamentos teóricos que nos forneçam ferramentas cognitivas para pensar a contemporaneidade.
Developing Metacognitive Instructors through a Guided Journal

Metacognitive instructors incorporate awareness and timely self-regulation in their teaching practice to support their current students’ learning. This exploratory study, using mixed methods, gathered empirical data to extend the work on student metacognition by documenting teacher experiences with metacognitive instruction, the impact of instructor use of a guided journal on the development of metacognitive instruction practices, and students’ perceptions of instructor responsiveness to their learning and engagement. Journal Intervention (N = 40) and Control (N = 33) instructors from five institutions and their students (N = 796) responded to multiple questionnaires throughout a semester. Data revealed significantly more baseline familiarity with and engagement in reflective teaching than metacognitive instruction for both groups. Within the Intervention group, qualitative data consistently suggested a positive impact from engagement with the journal, especially with respect to an increased focus on learning objectives and student engagement (rather than on content coverage) in pre-lesson planning, and on being aware of how students were achieving the learning objectives. Significant positive correlations were found between instructor use of the journal and student ratings of instructor responsiveness to their learning and engagement, and instructor use of effective instructional practices. Although instructors were enthusiastic overall about using the journal and incorporating metacognitive instruction, they did report barriers including time, existing habits, and uncertainty about alternate instructional practices. Based on our findings, we share strategies for using our journal prompts as a tool to facilitate faculty development of metacognitive instruction.
Faculty Empowering Faculty

Faculty are increasingly interested in engaging in the scholarship of teaching and learning (SoTL) across disciplines, necessitating educational development support. While many institutions utilize one-time workshops and faculty communities offering professional development funding, the case study presented in this article takes a different approach. The aim of the Engaged Teacher-Scholar (ETS) program is to support faculty growth in a process of becoming ETS leaders across the university campus. ETS leaders advance an individual SoTL research project and are trained to develop a plan for and offer professional development events to their department, college, and university related to SoTL. The article presents an overview of the program’s objectives, organization, and outcomes over four years of implementation. The article concludes with implications for implementation at other institutions.
Beyond Decoding the Disciplines 1.0
Authors: Pace David
Published: September 2021

Decoding the Disciplines has emerged as one of the foremost approaches to the scholarship of teaching and learning (SoTL) and is being used to increase learning across the globe. But it is often not recognized that the paradigm has undergone enormous changes since its appearance in 2004. The original model has been clarified and perfected, but scholars of teaching and learning have also expanded the scope of this work to include emotional, bodily, and social learning; created new roles for students in these investigations; and explored learning beyond the individual. Some of these changes have been so far reaching that they may be said to constitute a new version of the paradigm, Decoding 2.0. It is the purpose of this article to provide an overview of this paradigm’s development since it first appeared on the SoTL stage.
Using a Self-Determination Theory Approach to Understand Student Perceptions of Inquiry-Based Learning

Inquiry-based laboratory activities, as a part of science curricula, have been advocated to increase students’ learning outcomes and improve students’ learning experiences, but students sometimes struggle with open-inquiry activities. This study aims to investigate students’ perceptions of inquiry-based learning in a set of laboratory activities, specifically from a psychological (i.e., Self-Determination Theory) perspective. Students’ ratings of the level of inquiry in these activities indicate that students’ perceptions of inquiry align with the instructor-intended amount of inquiry in each exercise. Students’ written responses, explaining their ratings, indicate that students’ perceptions of the amount of inquiry in a given lab exercise relate to their feeling of freedom (or autonomy), competence, and relatedness (or support), during the inquiry-based learning activities. The results imply that instructors implementing inquiry-based learning activities should consider student motivation, and Self-Determination Theory can be a useful diagnostic tool during teaching development.

Student-faculty partnerships are a growing practice in scholarship of teaching & learning (SoTL) projects. They can foster greater student engagement in higher education and help advance teaching & learning experiences. For graduate students, in particular those pursuing academic careers, such partnerships can offer opportunities for development of their professional identities as emerging SoTL scholars. In this article, we expand upon previous theorizations of partnerships to include the unique attributes of graduate student partnerships, such as in terms of longer timeframes, increased complexity, and long-term goals. Drawing on a two-year SoTL study, we present a three-layer framework characterizing key attributes for a successful graduate student-faculty partnership: 1) individual attributes in a partnership, 2) collective attributes for a partnership, and 3) outcomes of a partnership. The framework is grounded in literature and illustrative examples from our experiences as graduate students and faculty members working together in partnership with a SoTL project. This framework offers a structured mechanism to inform, create, and enhance the capacity of student-faculty partnerships in SoTL research.
