Evolving the Master-Apprentice Tradition: A Pathway Back to a Student-Centered Pedagogy
Authors: Sherwood Travis
Published: August 2023

This article explores one of the oldest structures of formal education, the master-apprentice tradition, and how it has both persisted and evolved in the Western classical singing community in both name and practice. By studying the history of the master-apprentice tradition, contemporary pedagogues may contextualize their current practices while considering modifications that may yield a more student-centered pedagogy. The master-apprentice tradition is rooted in the experiences of the master. This teacher-centered pedagogy establishes a clear hierarchy of power in the teacher-student relationship. From an inferior position, students may become dependent on their teachers and ultimately silence their own technical and artistic instincts. Student and teacher interaction play a crucial role in the development of a student’s concept of self and their agency to embrace autonomy. Teachers and students often assume the dependent relationship of the master-apprentice tradition as it allows them to fulfill roles they understand, and earnestly continue to honor traditions established by the singers and pedagogues of the past. The period from the late nineteenth to the early twentieth century is often regarded as the “golden age” of Western classical singing. During this time, Manuel Garcia II, Mathilde Marchesi, the Lamperti’s, among others, codified much of the bel canto technique that continues to resonate throughout voice studios today. Much of the research concerning these revered pedagogues focuses on what they taught, but not how they taught. However, writings of the “golden age” pedagogues and their students infer that their primary focus was on the individual and independent development of each student. The teacher often relinquished the traditional role of “master,” and assumed the role of mentor and co-learner. By examining the how, contemporary pedagogues may realize adjustments in their teaching that honor and build upon the knowledge and experiences of students, ultimately devising a more student-centered pedagogy.

The Effect of Marijuana on the Voice
Authors: Balouch Bailey , Alnouri Ghiath , Sataloff Robert
Published: August 2023

Marijuana is derived from the cannabis sativa plant originating in central and southeast Asia. In recent years, there was increasing popularity and use of marijuana in addition to the legalization of its recreational use in parts of the United States. Singing teachers should be fam iliar with the voice effects of marijuana so that they may counsel students about marijuana usage. The authors sent a web-based questionnaire to adult voice center patients. The survey was designed to collect relevant demographic data, past laryngeal history, marijuana use history, and beliefs about effects of marijuana on voice. Those who used marijuana reported voice symptoms that they attributed to marijuana use, including hoarseness, breathiness and weakness. Smoking marijuana may cause immediate and long-term voice dysfunction. No positive changes to the voice have been identified. Further research is necessary to evaluate changes to the voice and safety of marijuana use, but voice teachers should be aware of the common adverse effects.

‘I’m Black but I don’t feel like I am’ – Young people’s experiences of living in transracial foster placements
Authors: Ansbro Yasmin , Collie Harriet , Lewis Matthew , Erin Libby
Published: August 2023

Transracial foster placements are the placement of ethnic minority youths with ethnic majority foster families. Some exploration into the challenges faced by ethnic minority youths living in transracial families have highlighted a loss of identity, managing racial discrimination and white privilege. So far, the research has looked at the perspective of care leavers, adoptees and carers, however there is little research that aims to understand the perspective of the child whilst they are living in transracial foster families. This pilot study aimed to explore ethnic minority youth’s experiences of transracial foster placements, with a view to developing a training package for foster carers. Eight ethnic minority young people, aged between 12 and 18 years old, living in transracial foster placements took part in semi-structured interviews about their lived experiences. Thematic analysis was conducted on the data and an inductive approach was taken. Three themes were identified: loss of identity; living in a white world; advice for foster carers. The findings of the study outline the many challenges that young people face living in transracial foster families and highlight the need for training, policy development and further research.

Abstract: The first step in creating new crop varieties is to evaluate current germplasm based on agro-morphological, physiological, biochemical, and molecular properties. The recent study compared the key morpho-physiological and biochemical characteristics among ten cotton genotypes. Ten cotton genotypes, including BH-249, BH-617, BH-227, BH-248, BH-613, BH-244, BH-247, BH-606, BH-184, and BH-600 were arranged in triplicates under randomized complete block design (RCBD) with plant-to-plant and bed-to-bed distances of 30 cm and 75 cm, respectively. Data obtained from the mature, fully-guarded plants were subjected to analysis of variance, and the results revealed the presence of significant variations in the studied plant traits. The correlation analysis revealed a significantly positive correlation of cotton yield with the plant height (r = 0.92**), transpiration rate (r = 0.79**), and ascorbic acid (r = 0.64**), while a significantly negative correlation with monopodial branches (r = -0.65**), virus effect plants (r = -0.59) and boll weight (r = -0.50). Similarly, seed cotton yield also showed a positive correlation with the number of bolls (r = 0.55) and peroxidase (r = 0.51), but these correlations were insignificant. Multivariate analysis approaches i.e., principal component, biplot, and cluster analysis, were used to classify and group cotton genotypes based on their performance. These analyses revealed that BH-247 and BH-606 were the most productive cotton genotypes. Therefore, these genotypes could be recommended for cultivation in core-cotton areas following extensive multilocation testing.

Published: August 2023

Anticoagulant therapy prevents and treats thromboembolic occasions like profound vein thrombosis, pneumonic embolism, and stroke. Warfarin, a vitamin K bad guy, has been the standard oral anticoagulant for quite some time. The study's main objective is to find that warfarin is associated with higher rates of epistaxis compared to direct oral anticoagulants. This cross-sectional study was conducted at Islamabad Medical and Dental College, Islamabad, from January 2023 till July 2023. Data was collected from 123 patients of both genders. The study population consists of adult patients prescribed anticoagulant therapy for various indications, including atrial fibrillation, venous thromboembolism, and mechanical heart valve replacement. Patients were identified from electronic medical records at the study site. In this study, a total of 123 adult patients receiving anticoagulant therapy were included. Among them, 62 patients were prescribed warfarin, and 61 were on direct oral anticoagulants (DOACs) (rivaroxaban, dabigatran, apixaban, or edoxaban). Warfarin and DOACs demonstrated similar safety profiles regarding other bleeding events and major adverse events. It is concluded that the study found no statistically significant difference in the incidence of epistaxis between the two treatment groups. Both Warfarin and DOACs showed similar safety profiles regarding other bleeding events and major adverse events, indicating that they are generally well-tolerated options for anticoagulation therapy in this patient population.
An Activity for Building Teaching Potential Designed on Community of Practice Cooperated with Lesson Study
Authors: Cojorn Kanyarat , Sonsupap Kanyarat
Published: August 2023

This paper proposes the development of an activity based on the community of practice (CoP) approach in collaboration with lesson study to enhance teaching potential. The CoP approach is utilized to elicit teachers' experiences and facilitate the sharing of teaching guidelines, while the lesson study method enables small groups of teachers to collaboratively design, teach, reflect on, and refine a class lesson. Drawing from semi-structured interviews, classroom observations, documentation, expert field notes, and focus groups, the proposed activity consists of four key components: 1) principle, 2) activity objective, 3) learning activity, and 4) learning evaluation. The learning activity encompasses four steps: educating, innovating, implementing, and reflecting. Each step comprises several sub-activities, with the innovating and implementing steps being iterative. The activity demonstrates a content validity of 0.95 and a suitability rating of 4.88. Furthermore, the participating teachers in this study exhibit increased self-confidence in constructing classroom activities and gained additional pathways for designing effective learning activities. The paper suggests that this approach can effectively foster the acquisition of new knowledge, the development of innovative practices, and the application of effective instructional strategies in the classroom.
Increasing Energy Efficiency of Central Cooling Systems with Engineered Nanofluids
Authors:   Blue Snow Energy, Sagaiyaraj Bernard
Published: August 2023

Buildings consume about 40% of the world’s energy consumption and of that, 65% is dedicated to cooling (or heating) systems. Central building cooling uses water as the main heat transfer medium. The nanoparticle fluid suspension exhibits thermal properties superior to water. The goal was to achieve the highest possible thermal properties with just the right amount of nanoparticles in a uniform and stable dispersion and suspension in water. This engineered nanofluid contains a uniform and stable suspension of graphene nanoparticles (GNP) in water. Using covalent functionalization, centrifugation and high-speed dispersion, the GNP remains in a stable suspension indefinitely. The nanofluid is applied to the closed loop of the chilled water system, where the heat transfer enhancement occurs at the fluid tubes within the evaporator and the tubing in the chilled water coils within the Air Handling Units(AHUs). The Proof of Concept (POC) completed in 2019 using laboratory-derived nanofluid resulted in energy saving that averaged at 32% compared with the baseline fluid (water). In 2022, a Scaled-Up mini plant produced GNP nanofluids in a commercial process environment, showing an average energy savings of 21%. These results were further verified and validated on small chilled water plants outside of the Scaled-Up plant with 25% and 29% average savings.
Do International Building Researchers Mostly Work Right Before the Deadline? Yes, According to Empirical Data
Authors:   Aalborg University, Johra Hicham , Hansen Anders Rhiger ,   Aalborg University, Rohde Lasse ,   Aalborg University
Published: August 2023

Academic work is characterised as increasingly time-pressured and deadline-driven. Moreover, increased use of online tools underpins flexible working hours. Does this make researchers work just before a deadline or a meeting (perceived as an intermediate deadline)? The "imminent deadline-driven work habit" hypothesis seems intuitively plausible since the research and academic world is notorious for heavy workloads and multiple parallel tasks and projects. The current article investigates the activity of several collaborative online documents from international building research projects as a function of the distance to a deadline or coordination meeting. A similar analysis is conducted on the submission data of an international conference on building physics. This empirical analysis supports the "imminent deadline-driven work habit" hypothesis. Finally, the article discusses the possible reasons behind the latter and the ensuing practical implications and recommendations for the management of collaborative research/academic work in energy, building physics and indoor environment.
Using Adaptive Behaviour Patterns of Open Plan Office Occupants in Energy Consumption Predictions
Authors:   Kaunas University of Technology, Tuniki Himanshu Patel , Bekö Gabriel ,   Technical University of Denmark, Jurelionis Andrius ,   Kaunas University of Technology
Published: August 2023

One of the factors that affects energy consumption in buildings is the level of control that occupants have over their environment, as well as their adaptive behaviour. The aim of this study was to focus on the adaptive clothing behaviour pattern, and to analyse its impact on energy consumption when integrated into a dynamic energy prediction tool. A questionnaire survey was conducted in an office building to collect the occupant behaviour data. The occupant clothing levels and the window opening behaviour were integrated into the dynamic energy performance prediction software, IDA ICE. The results of the simulations showed that the impact of adaptive clothing behaviour on energy consumption is relatively small, but it can meaningfully improve thermal comfort. Including adaptive behaviour in energy simulations can help in improving the accuracy of the energy performance and comfort predictions.
Energy retrofitting of non-residential buildings with effects on the indoor environment: a study of university buildings at NTNU in Trondheim, Norway
Authors:   Norwegian University of Science and Technology, Bjelland David , Hrynyszyn Bozena Dorota ,   Norwegian University of Science and Technology
Published: August 2023

The year 2050 is considered the deadline for achieving the European climate goal of net zero emissions, an essential sustainability milestone. Current strategies ask for higher retrofitting rates in the building sector, as most of today’s buildings will still be standing and be used in 2050, and longer. However, retrofitting strategies must consider energy and emissions reductions alongside social sustainability, targeting not only the building but also its users. Historically, the focus has been on indoor environmental quality, while other aspects of human well-being such as the quality of views were not addressed as frequently. Educational buildings can function as lighthouse projects, profiting from its many users as communicators. This article presents the retrofitting potential of the central building complex of the Gløshaugen campus of the NTNU in Trondheim in terms of energy, as basis to study the impact of retrofitting strategies on the indoor environment. The study consists of a selection of details, their building physical assessment, and a proposal of retrofitting measures. The results highlight the importance of human-centric definitions in the early (re-)design stages. Humancentric planning aspects can have diverse positive influences on the building’s users, especially in educational and other highly cognitive settings. Their impact however is strongly dependent on the selection of measures and their implementation. Interactions of the many aspects of well-being that can be addressed during retrofitting must be studied further as their interdependencies are often unclear and case specific. Human-centric retrofitting can function as a guide for upcoming mass retrofits throughout Europe for the sustainable achievement of climate goals.
Measurement of air change behaviour at Finnish apartment rooms
Authors:   Tokyo City University, Kayo Genku , Suzuki Nobue
Published: August 2023

While the expectation for natural ventilation is increasing under the context of COVID-19, fresh air at residential houses in Finland is basically guaranteed by mechanical ventilation systems. It means that natural ventilation is not considered as an available potential of ventilation in Finnish building regulation. Even if the mechanical ventilation system handles the air quality, the natural ventilation by window opening is expected to be a supportive measure. However, there is not enough measured data about how much air change is fulfilled by window opening. The article describes the evaluation of fresh air accessibility by window openings at six Finnish apartments. To understand the behaviour of air change, CO2 mass balance equation model was applied. The results of summer season clarified that the actual number of air changes are 085 to 1.54 times per hour with one-side opening. The CO2 mass balance model for apartments, which is a kind of tracer gas decay method, is an effective way to estimate the actual number of air changes without preventing occupants’ daily living. Since some buildings, such as residential, school, churches, are affected by the moisture problems, the management of moisture behaviour by both natural and mechanical ventilation is essential.
PRELUDE Roadmap for Building Renovation: set of rules for renovation actions to optimize building energy performance

Published: August 2023

In the context of climate change and the environmental and energy constraints we face, it is essential to develop methods to encourage the implementation of efficient solutions for building renovation. One of the objectives of the European PRELUDE project [1] is to develop a "Building Renovation Roadmap"(BRR) aimed at facilitating decision-making to foster the most efficient refurbishment actions, the implementation of innovative solutions and the promotion of renewable energy sources in the renovation process of existing buildings. In this context, Estia is working on the development of inference rules that will make it possible. On the basis of a diagnosis such as the Energy Performance Certificate, it will help establishing a list of priority actions. The dynamics that drive this project permit to decrease the subjectivity of a human decisions making scheme. While simulation generates digital technical data, interpretation requires the translation of this data into natural language. The purpose is to automate the translation of the results to provide advice and facilitate decision-making. In medicine, the diagnostic phase is a process by which a disease is identified by its symptoms. Similarly, the idea of the process is to target the faulty elements potentially responsible for poor performance and to propose remedial solutions. The system is based on the development of fuzzy logic rules [2],[3]. This choice was made to be able to manipulate notions of membership with truth levels between 0 and 1, and to deliver messages in a linguistic form, understandable by non-specialist users. For example, if performance is low and parameter x is unfavourable, the algorithm can gives an incentive to improve the parameter such as: "you COULD, SHOULD or MUST change parameter x". Regarding energy performance analysis, the following domains are addressed: heating, domestic hot water, cooling, lighting. Regarding the parameters, the analysis covers the following topics: Characteristics of the building envelope. and of the technical installations (heat production-distribution, ventilation system, electric lighting, etc.). This paper describes the methodology used, lists the fields studied and outlines the expected outcomes of the project.
Integration of smart building technologies costs and CO2 emissions within the framework of the new EPIQR-web application

The EPIQR method was developed between 1996 and 1998 within the framework of the European research programme JOULE II and with the support of the Swiss Federal Office for Education and Science. In its first versions, the EPIQR software and EPIQR+ that succeeded it, were desktop tools, allowing a precise diagnosis of the state of deterioration of an existing building and the elaboration of renovation scenarios including the different costs of the necessary works. However, deep refurbishment rate is still low. Climatic emergency state declared by most of the Swiss Cantons makes it necessary to search also for other strategies for urgent reduction of CO2 emissions. As part of the PRELUDE project, a web version of this tool has been developed to integrate both smart technologies and energy optimization actions. Some of them can be considered as soft actions, making it possible to develop a soft renovation roadmap for buildings that are not scheduled for renovation in the short term. As examples, the costs of optimization contracts, intelligent heating control, demand-controlled ventilation, abandonment of heat production from fossil fuels, integration of renewable energies into the building, and communities’ creation for self-consumption of photovoltaic production have now been modelled. Το help the residential building stock fit with the CO2 reduction of 60% by 2030 compliance and the “2000 W society” energy sobriety target by 2050, the EPIQR-WEB database includes the CO2 indirect emissions of each refurbishment action. Hence, this updated version enables the building diagnosis expert to evaluate and optimise deep refurbishment scenarios, from both financial and environmental point of view. Parallel calculation of CO2 indirect emissions with the calculation of refurbishment cost is done without extra time cost for the user. The paper will show the software new functions, the EPIQR-WEB database expansion and how its overall results can be used to meet the European Union Climate Target through a realistic and comprehensive investment plan.

Published: August 2023

This research project aims to document the spread of the biodegradation in wood frame buildings and, more specifically, to investigate the aggravating impact of the presence of the rotting fungus Serpula lacrymans in wood-based materials on the hygrothermal performance of wood-framed wall and floor assemblies. The proposed methodology is to calibrate a hygrothermal model of wood contaminated by varying stages of S. lacrymans. The S. lacrymans has a particular ability compared to other fungi in that it can move its water source to seek nutrients. Hyphen cords have been seen on brick and concrete elements, as a bypass mean to reach wood. Thus, this fungus is modelled with two means: modified hygrothermal properties and addition of parallel paths for moisture transfer in the assemblies. To develop these, characterizing healthy and contaminated wood is necessary to be used as input in the models. The simulations are performed for residential building envelope assemblies under current and future climatic conditions.

Processes for moisture concentration and temperature at different depths in a rather thick wall with mineral wool insulation are studied with a resolution of 1 minute. Damp processes in walls with thick layers of mineral wool differs a lot depending on the weather conditions. Any modelling of heat and moisture in building constructions need to consider this. The fact that the peaks in moisture concentration in some cases come hours before the peak in temperature is something that takes an explanation. It is possible, but not really sure, that this also may have influence on the risk for damage on the structures.

We are nowadays confronted with changes in moisture-related durability problems arising from climate change. As one example, building facades of historical buildings that before were hardly exposed to frost damage, may in future be exposed to an increase in frost-thaw cycling leading to a higher risk for moisture-related damage. An essential step in hygrothermal and durability analysis is the prediction of wind-driven rain (WDR). A computational fluid dynamics (CFD) Eulerian multiphase model provides WDR catch ratio charts. Building further on this work, methods are developed to predict WDR loads and moisture damage risks.

In this article, we presented our findings regarding an online project-based learning course, delivered to 64 students from the Federal University of Sao Paulo, Brazil, during the COVID-19 pandemic, in the second semester of 2021. The course had the goal of teaching Project Management by means of a competition (the Data Science Olympics). Our goal was to investigate the systemic impacts of the competition on learning. Data was collected by means of a questionnaire and from comments posted on the teams’ websites. We followed a convergent parallel mixed methods approach. We analyzed the data using a causal loop diagram to connect the insights gained with quantitative and qualitative results. Our findings were as follows: 1)The use of competition in a project-based learning centered course helped the students to develop project management and data science skills, and fostered metacognition and knowledge sharing opportunities. 2)The Data Science Olympics increased the students’ intrinsic motivation to learn. 3)The project-based teaching practices (scaffolding the students’ learning, giving meaningful feedback to the students, and managing the activities) facilitated the students' learning. 4)The problems the students faced throughout the Project (dropouts, communication problems, lack of commitment, difficulty scheduling online team meetings) impacted negatively on the students' motivation.

The aim of this study was to evaluate the precision and compliance with international guidelines in the medical certification of cause of death at a rural tertiary care center in Western Maharashtra, India. Additionally, we aimed to identify prevalent errors and discrepancies while investigating the factors that influence the medical certification process at the center. By conducting this research, we sought to obtain comprehensive insights into the accuracy of cause of death documentation and contribute to enhancing the adherence to standardized practices in this crucial aspect of medical practice. The Medical Certificate of Cause of Death (hereafter MCCD) is an important document issued by a doctor for which the World Health Organisation has prescribed a standard format, together with the International Classification of Diseases (hereafter ICD). In it, the doctor records the time, causes and circumstances of the deceased person's death. 615 MCCD forms were available during two years from the MAEER MIT Pune’s MIMER Medical College & BSTR Hospital, Talegaon Dabhade and Pune. All of them were scrutinized for the completeness of the certificate and tried to find out the cause of death in which underlying cause of death was written. Data was analyzed and expressed in the percentage form. Ethical clearance was obtained from the Institutional ethics committee (No. IEC/MIMER/2021/761). Main leading cause of death in the present study was disease of circulatory system 868 (29.35%), followed by Neoplasm (16.54%) and Certain infectious and parasitic disease (16.44%). The present study showed incompletely and inaccurately filled MCCD forms. Therefore, adequate training and proper sensitization of the doctors regarding the usefulness of MCCD data is required.
Effectiveness of educational interventions to reduce healthcare- associated infections in adult intensive care units: a scoping review

Healthcare-associated infections (HAIs) represent a serious threat to patients admitted to hospitals and particularly to ICUs, as they contribute to increased mortality, prolonged length of stay and consequently increased healthcare costs. The aim of the present scoping review was to evaluate the effectiveness of educational interventions for the reduction of these infections in the adult ICU. A systematic literature search was conducted from December 2022 to March 2023, making use of official electronic databases such as PubMed, SCOPUS, CINAHL and Cochrane Database of Systematic Reviews; the key terms used for the search were the following: "Healthcare Associated Infections"; "educational interventions"; "intensive care unit" in all possible combinations and making use of the Boolean operators "AND" and "OR"; the application of the PRISMA methodology allowed a final screening of ten[MOU2] (10) studies on which the present review was based. In the selected studies, it was evident that education was essential and should be shared between multidisciplinary care teams, patients, their families, and caregivers. Statistical significance was found in two studies that demonstrated a reduction in HAIs. Despite considerable variation in the duration and type of educational intervention, the importance of establishing continuing education to maintain intervention results.

Published: August 2023

La falla cardiaca (FC) afecta a más de 23 millones de personas en el mundo. Se ha demostrado que las intervenciones de enfermería mejoran el conocimiento, comportamientos y reingresos hospitalarios. Asimismo, se recomienda realizar alguna actividad física de tipo aeróbico no sólo como medida preventiva, sino que los estudios reportan que se mejora la calidad de vida de los pacientes con enfermedades crónicas y aumenta su bienestar cuando se mantienen activas y realizan sus actividades habituales. Esta reflexión presenta generalidades de la cultura de la actividad física y los beneficios en los pacientes con enfermedades crónicas como la falla cardiaca; está comprobado que el ejercicio físico contribuye a mejorar los síntomas y a aumentar la autoestima. La FC limita la vida de los pacientes por la variedad de síntomas de la enfermedad, pero la evidencia describe la importancia de la prescripción de la actividad física la cual debe hacer parte del tratamiento integral de los pacientes con esta condición.
