Structural analysis of Cu-based FeCr reinforced composites prepared by mechanical alloying
Authors: Yilmaz S. O. , Teker T. , Aydin S.
Published: July 2023

Production and structural investigations of Cu-based FeCr reinforced composite were performed by using mechanical alloying, optical microscope, scanning electron microscope, X-ray diffraction and hardness test. The increment in FeCr addition caused the increment in the cold deformation rate. This situation resulted in breakage of the powder particles throughout mechanical alloying.

Thus, the grain dimension of the FeCr powders decreased and the Fe wt.% in the CuCr powders advanced. The collision force between the Cu-Cr powder and the grinding ball weakened with the increase of FeCr concentration and resulted as higher reinforcement size. After mechanical milling, FeCr grains decreased in size more than copper grains due to the ductility of copper grains. The smaller crystals occurred after grinding, and increased the grain boundary zone for further spread of Cr into the Cu. Despite the high sintering process, the high sintering temperature improved the compactness of the alloys, but caused coarsening of the nanoparticles. The mechanical alloying time, reinforcement wt.% and sinter temperature were effective on the micro-hardness of the microstructure.
Evaluation of nickel shot peening process on strength of friction stir welded AA2014-T6 aluminum alloy joints
Authors: Mallieswaran K. , Rajendran C. , Padmanabhan R. , Rajasekaran S.
Published: July 2023

The best aluminum alloys for construction are those that incorporate copper. However, welding engineers find it difficult to join aluminium and its alloys as a result of cracking. One of the popular methods for joining nonferrous materials, especially aluminum alloys, is friction stir welding (FSW). A tensile strength of 75 % to 85 % of the basic material strength is produced by FSW joints. The majority of studies have documented a reduction in strength as a result of incomplete melting, creating a soft region at the boundary between the thermo – mechanically influenced zone and the stir zone. The current effort has focused on using the shot peening method to reduce the softness at the interface. According to the test findings, the nickel shot-peened joint produced a stronger joint than the traditional FSW joint. The shot-peened joint has gained 7 % additional strength compared to untreated joint.
Scale-bridging contrasting and characterization of multi-wire submerged arc welds and electron beam welds in steels
Authors: Herges A. , Pauly C. , Müller M. , Britz D. , Mücklich F.
Published: July 2023

For a comprehensive microstructural characterization of welds, a scale-bridging analysis of the microstructure is required. It is the only way to identify all microstructural characteristics relevant for the mechanical properties which, in turn, may cover several observation scales. The analytical methods used range from etchings for the macroscopic evaluation of the weld and heat-affected zone to the detection of so-called “local brittle zones” (LBZs) in the micrometre range. This paper will study weld joints in low-alloy steels produced by multi-wire submerged arc welding and electron beam welding. Macro and micro etching as well as electropolishing will be used for microstructural contrasting. Scanning electron microscopy will be performed to identify the finely dispersed carbon-rich secondary phase. Electron backscatter diffraction will enable the identification of so-called martensite/austenite regions (MAs) capable of acting as LBZs.
Vibratory polishing of multiphase CuZn30//CuZn80 diffusion pairs for electron backscatter diffraction (EBSD) characterization
Authors: Möbius J. , Lippmann S. , Seyring M.
Published: July 2023

The influence of vibratory polishing time on the quality of EBSD mappings of a multiphase microstructure is investigated and optimized for CuZn30//CuZn80 diffusion couples. The diffusion couples consist of four different phases whose hardness varies between 70 HV0.1 and 454 HV0.1. These are first mechanically ground, polished and finally prepared by vibratory polishing. A vibratory polishing of 2 h provides for all phases the highest quality of the recorded Kikuchi patterns (Image Quality values) and the highest correct assignment of the individual pixels of the mapping. Preparation artifacts, such as relief formation, only appear at higher vibratory polishing times (> 2 h). A vibratory polishing of the diffusion couples of 0.5 h already provides sufficient surface quality for EBSD analyses.
Eine jüdische Stimme vor Gericht
Authors: Stengel Katharina
Published: July 2023

Die Einflussmöglichkeiten von Opfern der nationalsozialistischen Terrorherrschaft in den bundesdeutschen Strafverfahren gegen NS-Verbrecher waren sehr begrenzt, denn als Zeuginnen und Zeugen hatten sie den streng formalisierten Anforderungen der Strafjustiz zu entsprechen. Seit den 1950er Jahren versuchten jüdische Organisationen daher, über Nebenklagen in den Prozessen mehr Einfluss zu gewinnen und eigene Forderungen deutlich zu artikulieren. Katharina Stengel zeichnet die teils kontroversen Diskussionen innerhalb der internationalen jüdischen Organisationen nach, untersucht die Bedeutung der Nebenklage im Frankfurter Auschwitz-Prozess und einigen anderen NS-Verfahren und geht auf die wichtige, aber kaum bekannte Mithilfe der jüdischen Organisationen bei der Vorbereitung der Prozesse ein.
Das Institut für Zeitgeschichte und die Affäre um die gefälschten Hitler-Tagebücher 1982/83
Authors: Kutzner Maximilian
Published: July 2023

Die Veröffentlichung der gefälschten Hitler-Tagebücher im April 1983 löste unter den bundesdeutschen Historikern erregte Diskussionen aus. Konnten die Tagebücher überhaupt echt sein? Das Institut für Zeitgeschichte (IfZ) war bereits vor ihrer Veröffentlichung in Kontakt mit maßgeblichen Akteuren des späteren Skandals. In der Phase zwischen der Ankündigung des Funds und der Entlarvung als Fälschung spielten sich vielschichtige Prozesse der Selbstverortung in der Institutsleitung ab. Die Dokumente aus dem IfZ-Archiv zeigen, dass die gefälschten Tagebücher auch ein Prüfstein für die gesellschaftliche Rolle der Zeitgeschichte und ihrer maßgeblichen Vertreter waren.
Stabilizing a Keynes-Minsky Model of Financial Fragility
Authors: Dunn Bill
Published: July 2023

The profound insights provided by Minsky's theory of financial instability are insufficient. On the one hand, as Marxists and other critics have pointed out, they tend to dissociate finance from the instability-creating dynamics of the wider economy. On the other hand, they tend to depict the state as an exogenous, stabilizing, influence. This creates an inherent tension in Minsky's analysis, which also insists, “stability is destabilizing.” A Marxist understanding resolves this tension. The state is an essential and active component of capitalism and its contradictions. State interventions may attenuate some of capitalism's destabilizing processes but these displace rather than eliminate the underlying contradictions and themselves contribute to longer-term instability and crises.
Free Digital Labor as a New Form of Exploitation: A Critical Analysis
Authors: Vercellone Carlo , Di Stasio Antonio
Published: July 2023

The notion of Free Digital Labor has emerged at the center of scientific debate with the advent of platform capitalism. This notion denotes the apparently free activity that users perform on digital platforms, producing, often unknowingly, data without any monetary remuneration. It is therefore particularly useful in signaling the progressive loss of a clear distinction between working time and leisure time. The paradigmatic example of the valorization of these activities is provided by Google and Facebook. Their accumulation system is based on a multi-sided market logic, in which the extraction of user data is combined with online advertising. Recent debate has raised several objections to the notion of Free Digital Labor. Our aim is to clarify the terms of the debate and to revive the relevance of the notion of Free Digital Labor through a historical and theoretical analysis of the transformations of the relationship between capital and labor.
Whose Labor? Labor, Appropriation, and the Very Idea of Full Automation
Authors: Borg George
Published: July 2023

Is a “fully automated” capitalism possible? According to Marx's labor theory of value (LTV) and the theory of surplus-value derived from it, a fully automated economy cannot be profitable. To refute the theory, critics have put forth various thought experiments claiming to show that a fully automated but profitable capitalist economy is conceivable. I argue that the thought experiments fail to demonstrate conceivability, because they misunderstand the role of labor in a commodity economy. In the latter, labor is a means for acquiring the property of others, and so it cannot be eliminated so long as the economy is based on the commodity form. Quite apart from issues of technical feasibility, then, the idea of a fully automated commodity economy is conceptually incoherent. The ineliminability of labor under the commodity form reflects the limits to the socialization of production this form imposes.

Authors: Pingale Ajay D. , Kachare Pravin S.
Published: July 2023

Over the past few decades, research on impact dampers has grown significantly, leading to numerous analytical and experimental investigations in that field. Vibrations can harm industrial equipment and cause process errors. Particle impact damper has a significant impact on lowering vibration and has been broadly implemented in various engineering applications. This work deals with the theoretical modeling for cantilever beam and fixed-fixed beam attached with a cylindrical enclosure filled with particles. Transient and forced excitations are considered to trace the motion of the primary mass with respect to time. Also, theoretical modeling of particle arrangement in enclosure, condition for particles to detach from base or ceiling of enclosure, motion of particle after detachment from enclosure, and mechanism of collision and friction of particles are discussed and presented in detail. Theoretical models proposed in this study can be used to generate theoretical readings for practical engineering applications.

The highest application of 3D printing is for hobby (i.e., 67% of the respondents), while the highest response for experience in 3D printing is 28% with 1–3 years of experience. Creality 3D printer brand is the most selected printer brand, with 64.7% of the respondents using the brand. 33% of the respondents used the printer at a heavy usage rate of 5 days per week, which is the highest response. For the material used, 85.4% of the respondents agreed that they normally used polylactic acid, while 79.3% of the respondents selected Cura as the most used software. Furthermore, 79.3% of the respondents stated that the infill percentage setting as the most changed setting, while 63.4% of the respondents agreed that bed levelling is the most common problem in 3D printing. In the opinion section, most of the respondents believed that 3D printing technology is still new and should be taught in schools. Based on the results, the research has successfully established the demographics and usage among 3D printer users in Malaysia.
A numerical investigation of effects of chemical kinetic mechanisms on the structure of turbulent jet diffusion H2/air flame with Lagrangian PDF method
Authors: Senouci Mohammed  , BOUNIF Abdelhamid , MEROUANE Habib , BOUKHELEF Mohamed
Published: July 2023

Many physical phenomena characteristic of reactive flows are controlled by the detail of the chemical kinetics of combustion. These include, for example, the ignition and extinction of a flame and the formation of polluting species. These phenomena require the use of detailed kinetic schemes including hundreds of species and thousands of reactions.The main objective of this work is to highlight the influence of chemical kinetics on the structure of turbulent jet diffusion H2/air flame. Five improved hydrogen kinetic mechanisms have been tested in order to validate, compare and evaluate their effect on the scalar and dynamic fields of such flames. The effect of number particles used in Lagrangian PDF method on the temperature evoltution is also studied. A hybrid method, PDF Lagrangian coupled to the RSM turbulence model, is used in this work, for the numerical simulation. The micro-mixing term of the TPDF is modeled by the EMST model. This model, which describes well the physical process of mixing, has shown its capabilities to give good numerical results. The impact of these mechanisms on the numerical results of scalar and dynamic fields was discussed and compared with the experimental data. The scalar field is well influenced by the choice of the chemical kinetic mechanism. This is not the case of the dynamic field. A good agreement with experience is observed for detailed kinetic mechanisms. However, it has been noticed that simple and reduced mechanisms give also satisfactory results, particularly the reduced kinetic mechanism R12 wich includes 12 reaction and can be considered as a compromise among the five kinetic mechanisms. These mechanisms allows for a significant reduction in CPU time and storage memory. It was also observed that, for the two chemical kinetic mechanisms R12 and R27, the number of particles only affects the radial evolution.
Preparation of bamboo dissolving pulp for textile production. Part 1. Study on prehydrolysis of green bamboo for producing dissolving pulp
Authors: Ma Xiaojuan , Huang Liulian , Chen Yanxi , Cao Shilin , Chen Lihui
Published: July 2023

Prehydrolysis was used as the first treatment of bamboo materials for producing high dissolving pulp for textile applications. In this paper, green bamboo (Dendrocalamopsis oldhami)was hydrolyzed in water, and the hydrolysis process was optimized. The morphology and super-molecular structures of the raw material and prehydrolyzed material were studied by SEM and XRD, respectively. Based on the optimum conditions, a study of the kinetics and mechanism showed that pentosan dissolution during the hydrolysis process was a first order reaction. When cooking temperature was 150 oC, 160 oC, 170 oC, and 180 oC, the corresponding reaction rate constants were 0.00411h-1, 0.00495h-1, 0.00730h-1, and 0.00925h-1, respectively. The activation energy was 44.94 kJ/mol based on the Arrhenius empirical equation. SEM results revealed that after the pre-hydrolysis process, the bamboo structure became loose because of hemicellulose dissolution, which created a favorable environment for chemical penetration in the subsequent treatment. Furthermore, the degree of crystallinity was increased from 45.43% to 57.06% during the prehydrolysis. Both the treated and the untreated fibers were assumed to be cellulose I.

Published: July 2023

The objective of the study is to develop a new filler for the production of natural filler thermoplastic composites using the waste rapeseed stalks. The long-term water absorption and thickness swelling behaviors and flexural properties of rapeseed filled polypropylene (PP) composites were investigated. Three different contents of filler were tested: 30, 45, and 60 wt%. Results of long-term hygroscopic tests indicated that by the increase in filler content from 30% to 60%, water diffusion absorption and thickness swelling rate parameter increased. A swelling model developed by Shi and Gardner can be used to quantify the swelling rate. The increasing of filler content reduced the flexural strength of the rapeseed/PP composites significantly. In contrast to the flexural strength, the flexural modulus improved with increasing the filler content. The flexural properties of these composites were decreased after the water uptake, due to the effect of the water molecules.

Published: July 2023

La presente investigación examinó la importancia de los actores sociales en el ordenamiento y gestión territorial de los gobiernos locales del Perú. Para este fin se empleó la revisión sistemática, que permitió analizar cuarenta y ocho publicaciones sobre el tema de estudio de los últimos cinco años. Actualmente, las normas legales sobre planificación urbana se dan a nivel nacional, a pesar de que la problemática es diferente en cada gobierno local, generando así conflictos sociales en el manejo y gestión de los territorios. Dichos problemas, son ocasionados por la falta de un ordenamiento territorial transversal en todos los sectores, el cual debe incluir lineamientos generales a ser desarrollados por cada gobierno local según sus características físicas y bioclimáticas. La principal conclusión del estudio es que los diferentes gobiernos locales enfrentan desafíos al momento de planificar sus territorios y, consecuentemente, en la zonificación y uso del suelo para futuras edificaciones en los diferentes sectores.

The sanitary emergency installed in the world generated by the pandemic COVID-19 instigates the search for scientific strategies to mitigate the damage caused by the disease to different sectors of society. The disease caused by the coronavirus, SARS-CoV-2, reached 216 countries/territories, where about 20 million people were reported with the infection, and more than 740,.000 died. Given the situation, research involving the development and validation of new antiviral molecules, especially against the SARS-CoV-2 virus, is highly relevant. In this work, a in silico study was carried out to evaluate the inhibitory power of phytoconstituents from Anacardium occidentale L. against Mpro enzyme from COVID-19 virus. The molecular docking simulations were performed to understand interactions between some phytochemicals present in A. occidentale against the Mpro enzyme from SARS-CoV-2, the amentoflavone and agathisflavone molecules showed the best affinity energy in the value of -8.0 kcal/mol and -8.3 kcal/mol, respectively. The molecular dynamics results indicated that the agathisflavone ligand had interactions more stable and a highest interaction potential energy with the Mpro enzyme than the amentoflavone ligand.
The Ukrainian Family in the Conditions of War
Authors: SLYUSAR LIUDMYLA
Published: July 2023

The purpose of this study is to determine the problems and risks for the Ukrainian family, which is the basic institution of society, in the conditions of the Russia’s war against Ukraine, and its role in preserving the human potential of country. The study is based on information from open sources, expert assessments, data from the State Statistics Service of Ukraine, and sample survey materials. The research was carried out using such methods as comparative analysis, generalization and induction, survey, system approach. The family is a primary and main center of society, which ensures the physical (biological) and sociocultural reproduction of generations of the human community. In recent decades, the development of the family in Ukraine took place in the same direction as in other European countries. Russia’s war against Ukraine deformed the natural processes of life and development of the Ukrainian family. Great human losses, the destruction of the environment necessary for life (housing, social and economic infrastructure, natural environment), forced mass migration made it extremely difficult to implement the main specific functions of the family (child-bearing, upbringing, and maintenance of children), but activated its protective function. Family practices in the conditions of war and forced migration testify to powerful family ties and their special importance in the crisis period. In the conditions of war and the socio-economic disorganization caused by the war, family becomes a support: family solidarity, mutual assistance, care, the exchange of activities and material resources between family members allow to sustain living, and sometimes to protect life. A significant part of the forced migrants, who left the dangerous areas, receive assistance, and often move to relatives in safe regions of the country. Socio-psychological functions of the family acquire protective character. At the same time, the war aggravated the problems of Ukrainian family and provoked new risks. The consequence of the full-scale war was the reduction and deformation of the marriage potential and negative changes in the marriage and family structure of the population: an increase in the number of widowed; single-parent families and families where children live without parents with relatives; single people of the oldest age. The increase in the number of orphans and children deprived of parental care (whose parents have died, are in captivity, forcibly deported, their whereabouts are unknown, etc.) is one of the most serious consequences of the war. Weakening of marital relations due to mobilization and large-scale migration with gender disproportions may lead to an increase in divorce rates in the future. An increase in the number of single-child families among families with children is to be expected, although its significant growth was a problem even in the pre-war years. The changes in the Ukrainian family may be fully understood only a few years after the end of the war.
Housing Affordability Issues in Ukraine

Published: July 2023

The article is dedicated to the analysis of population’s housing provision in Ukraine and its certain regions considering the methodological features of assessing housing affordability indicators, as well as the losses in the housing stock as a result of military invasion. The purpose of the paper is the methodological determination of housing affordability indicator, assessment of its pre-war trend in Ukraine; and determination of an acceptable for modern conditions institutional mechanism for improving housing affordability based on the principle of rent. The novelty of the research is the substantiation of use of permanent housing lease mechanism. These schemes can be implemented at the state and regional levels with the direct participation of investors and local self-government bodies within the framework of public-private partnerships. In the paper the pros and cons of the current mechanisms of housing construction and obtaining are identified; prospective directions and possible financial mechanisms for state housing policy implementation in the current condition of construction industry and population welfare are shown. Research methods are the following: correlational, analog, time series for the analysis of regional differentiation of housing affordability in Ukraine. Housing affordability has become much more complicated due to the need to restore damaged and destroyed dwellings. In view of current situation, prospective dynamics of living area commissioning indicator aimed at bringing the level of housing provision of Ukrainian citizens closer to the indicators of European countries was determined. In the absence of official housing purchase estimates at the national level, the ratio of median cost per square meter of living area to the median wage was used as the housing affordability ratio. The housing affordability ratio for the regions of Ukraine was calculated. According to the generally accepted classification of housing markets by affordability criterion, the purchase of housing in the country is significantly complicated. The correlation between the housing affordability indicator and the living area commissioning indicator was calculated, which was negative and indicated that the regional programs for providing the population with housing are critically unsatisfactory. The positive and negative features of the financial instruments for ensuring the housing affordability for the population and their compliance with the strategic goals of the housing policy development were determined. The financial and organizational mechanism of lease as a target vector for providing the population with housing was proposed.

The subject of research in the paper is the process of forming a criterion base to evaluate the effectiveness of carrying out modification changes in a transport category aircraft. The goal is to develop supporting criteria for making decisions regarding the expediency of modification changes, namely, during design, during production, and at the stage of its operation, at each stage of the life cycle of a new transport category aircraft. The complexity of the task lies in the need to develop a model for evaluation of the consequences of changing the aircraft for each stage separately, which would collectively determine the integral effectiveness of its modification. To evaluate the efficiency of basic aircrafts in operation, there are a number of economic indicators of their efficiency, in particular, the cost of an aircraft hour and the transportation of one ton of cargo per one kilometer, which are only partially taken into account when analyzing the efficiency of aircraft modifications, although in the case of aircraft transport category, specific cost criteria for the entire life cycle both for the base aircraft and for its modification is required. For their development, a method of estimating the cost of the entire life cycle of the aircraft is proposed, as well as a method of dividing modification changes according to the parameters of the upper level (PMD), which is used at the stage of designing the devices, and the lower level (PPO) for the operational stage. On the basis of and taking into account the specifics of the specified methods, indicators of additional labor costs that arise during the implementation of modification changes in the conditions of production and at the stage of aircraft operation have been developed. The proposed criteria take into account indicators of the transport efficiency of heavy aircraft modifications and the integral efficiency of the modification, taking into account the costs at all the main stages of the life cycle of the modification. The scientific novelty of the obtained results is as follows: the supporting criteria for the adoption of decisions regarding the expediency of modification changes at each stage of the life cycle of a new transport category aircraft are proposed, i.e. during design, under the conditions of production and at the stage of its operation. Such criteria will ensure the integral efficiency of the transport aircraft modification.
Gastrointestinal Bleeding in the Neonate: Updates on Diagnostics, Therapeutics, and Management
Authors: Reeves Patrick T. , James-Davis La’Toya , Khan Muhammad A.
Published: July 2023

Gastrointestinal bleeding (GIB) is a relatively uncommon presentation in the NICU. GIB in neonates includes a broad spectrum of disease morbidity, from minor reflux symptoms and growth failure to severe, clinically significant anemia requiring critical care resuscitation. Over the last several years, multiple diagnostic tools including fecal calprotectin and bedside ultrasonography have emerged and demonstrated utility in the early recognition of sources for GIB in neonates. Further evidence has continued to show that traditional medical therapy with intravenous proton pump inhibitors is well-tolerated, and that upper endoscopy has limited diagnostic and therapeutic value. Finally, additional research and quality improvement investigations are warranted to determine how best to prevent, recognize, and manage GIB in critical neonates.
The Complete Blood Count: A Practical Tool for the Pediatrician
Authors: Pabón-Rivera Samuel , Flores Raina R. , Frei-Jones Melissa
Published: July 2023

Every child should have a baseline hematology evaluation with hemoglobin and hematocrit levels starting at age 12 months, or younger if clinically indicated. Although history and physical examination provide key information needed to diagnose blood disorders, the addition of a complete blood count (CBC) with differential count and reticulocyte count allows the clinician to narrow the differential diagnosis and tailor the subsequent evaluation. The interpretation of CBC results is a skill that requires practice. Every clinician can learn to identify possible diagnoses before consulting a specialist. This review provides a step-by-step approach for CBC interpretation with tools to help the clinician diagnose and interpret the most common blood disorders seen in the general pediatric clinic or inpatient setting.

Indonesia is an archipelago where eight out of 38 Indonesian provinces are characterized by islands. Thus, the connectivity between islands is substantial in supporting economic development. This research aims to display the possible maritime connection and excavate the obstacles to improving maritime connectivity in the area. This research is qualitative comparative research using the Miles and Huberman model and analyzes it with the Graph Connectivity Node theory, comparing it with actual nodes in the areas and materializing the possible challenge and obstacles in connecting the nodes using RCA and 5 Whys Analysis as the tool. The data is obtained through two ports located in Kepulauan Riau Province. The research finds that the obstacles in connecting the node are infrastructure, budget, and interconnection with other forms of transportation. Therefore, the impact of this research on improving the node lies in the policy to overcome the obstacles encountered.
“It’s Like we Have Our Own Rhythm”. Music Therapeutic Affect Regulation in a Case Study of a Traumatized Patient in Mental Health Treatment
Authors: Bjørke Oda Dypvik , Beck Bolette Daniels
Published: July 2023

This article explores how music therapy can contribute to the treatment of individuals with affect regulation challenges related to relational traumatic experiences. Affect regulation was investigated through a case study of music therapy with a man with complex post-traumatic stress disorder. The case represents clinical work in a psychiatric hospital, on a ward for ambulatory treatment of people with severe mental illness and substance abuse challenges. Based on theories of communicative musicality, intersubjectivity and traumatology, an analysis of transcripts of music therapy improvisations and verbal interaction is presented and discussed. The method used in the study is an abductive explanatory thematic analysis grounded in hermeneutic interpretation of data. The two main themes emerging from the analysis are “Musical interaction as co-regulation” and “Music as a creative (re)source” with the subthemes “Musical interventions serves as a regulation tool”, “A process from regulation to relationship, “Musical self-agency” and “Music therapy as an experimental playground”. Further studies on affect regulation in clinical music therapy are warranted.
Navigating an Internship at a Residential Education and Medical Centre in Rural Kenya
Authors: Luvai Mufu
Published: July 2023

Little has been written from the perspective of a Kenyan student completing a music therapy internship at a mental rehabilitation institution in rural Kenya. At the time of writing this essay, music therapy was still not recognized as a profession in Kenya. This observation inspired me to fill a knowledge gap, encourage students to share their own experiences, and in the process, encourage aspiring music therapist students pioneering in other parts of Africa. I have divided my learnings into five themes based on my reflexive notes: (1) Mindset: Something out of nothing, (2) A staggered internship, (3) Transferring theory to practice, (4) Navigating workplace culture, and (5) Cultural sensitivity and musical multicultural competence. I advise the reader to take into conside­ration that these are my thoughts as a student undergoing a transformation. The essay not only describes my journey as an intern, but also provides me with a template for further reflections in my work as a music therapist. Compiling this essay has taught me that words on paper carry significant weight and have the ability to bring resolution to a problem or propagate it further. Through the internship, I came to learn that it is the role of music therapists to see beyond adversity; ignite hope where there is despair, and hold on to a future of possibilities.

Background: This paper presents the results of an arts-based, phenomenological research project in which members of a therapeutic community choir for people living with dementia and their family and friends reflected on their experiences of singing together pre and post the transition to online sessions as a result of the COVID-19 pandemic.
Method: Eleven choir members (three living with dementia and eight family care-partners) participated in interviews about their experience of the choir and its transition to an online format during the COVID-19 pandemic. Interviews were conducted in either a traditional, semi-structured interview format, or as a collaborative songwriting session, and participants were able to choose the format that they preferred. Transcripts of the interviews and songs that were composed were analysed using an adapted Interpretative Phenomenological Analysis and arts-based research method. Participants verified key themes that emerged from the analysis, which formed the basis of an 18-part Song Cycle, which included two original songs by participants, and 16 songs composed by the first author.
Results:  Eighteen sub-themes were generated from the analysis, which are expressed as songs and grouped into four overarching themes or ‘Movements’: i) the dementia experience; ii) the choir experience; iii) the COVID-19 experience; and iv) the virtual experience. The songs depict how participants experienced each of the overarching themes, and revealed challenges, new opportunities and resilience.
Conclusion: Navigating COVID-19 while living with or caring for someone with dementia was challenging. The virtual choir format was acceptable, provided relief from the stress of COVID-19, and kept members connected, however, there were technological limitations that made the experience challenging at times.
Characteristics of Music Therapy With Beneficial Impacts on Agitation in Dementia

Published: July 2023

Several reviews in recent years have reported evidence of the effect of music on the serious problem of agitation in dementia. Some reviews draw different conclusions, however, which actualizes the need for studies that examine characteristics of music therapy with beneficial impacts on agitation. In an instrumental case study, documented through qualitative interviews, recordings of group meetings, and patient record excerpts, we examine how music was used intensively in interaction with a man in his 70s at a unit for persons with dementia. Music therapy was often able to ease his agitation and was especially valuable in a period when he needed to be isolated due to a suspected coronavirus infection. However, the interventions did not work every time, and his responses differed considerably. The case illustrates that music therapy can address agitation in dementia for some clients, but the claim must be qualified. Potential characteristics of music therapy with such an ability might be i) situated use of the most favored music, ii) careful adjustment to signs of pain and discomfort, iii) sustained effort to build trustful relationships, iv) transferable interaction patterns of health musicking, and v) sufficient access to attention and support for the client(s) during the musical interventions.
