Aims

Internal hemipelvectomy without reconstruction of the pelvis is a viable treatment for pelvic sarcoma; however, the time it takes to return to excellent function is quite variable. Some patients require greater time and rehabilitation than others. To determine if psoas muscle recovery is associated with changes in ambulatory function, we retrospectively evaluated psoas muscle size and limb-length discrepancy (LLD) before and after treatment and their correlation with objective functional outcomes.

Methods

T1-weighted MR images were evaluated at three intervals for 12 pelvic sarcoma patients following interval hemipelvectomy without reconstruction. Correlations between the measured changes and improvements in Timed Up and Go test (TUG) and gait speed outcomes were assessed both independently and using a stepwise multivariate regression model.

Results

Increased ipsilesional psoas muscle size from three months postoperatively to latest follow-up was positively correlated with gait speed improvement (r = 0.66). LLD at three months postoperatively was negatively correlated with both TUG (r = -0.71) and gait speed (r = -0.61).

Conclusion

This study suggests that psoas muscle strengthening and minimizing initial LLD will achieve the greatest improvements in ambulatory function. LLD and change in hip musculature remain substantial prognostic factors for achieving the best clinical outcomes after internal hemipelvectomy. Changes in psoas size were correlated with the amount of functional improvement. Several patients in this study did not return to their preoperative ipsilateral psoas size, indicating that monitoring changes in psoas size could be a beneficial rehabilitation strategy.

High-efficiency square-hole single-mode waveguide photon sieves for THz waves
Authors: Cheng Changjie , Cao Qing , Bai Lihua , Li Chaoyue , Zhu Jirui , Chen Wenxuan , Mao Yaxing
Published: March 2023

The photon sieve has had the problem of low diffraction efficiency since it was proposed. Dispersion from different waveguide modes in the pinholes also reduces the quality of focusing. To overcome the above drawbacks, we propose a kind of photon sieve working in the terahertz band. In a metal square-hole waveguide, the effective index is determined by the side length of the pinhole. We adjust the optical path difference by changing the effective indices of those pinholes. When the thickness of the photon sieve is fixed, the optical path in a zone is set to be a multilevel distribution from 0 to λ. In this way, the optical path differences caused by the waveguide effect of pinholes are used to compensate for those caused by the positions of pinholes. We also derive the focusing contribution of an individual square pinhole. The simulated example shows a 60 times increase in intensity than that of the equal-side-length single-mode waveguide photon sieve.

Image sensors are must-have components of most consumer electronics devices. They enable portable camera systems, which find their way into billions of devices annually. Such high volumes are possible thanks to the complementary metal-oxide semiconductor (CMOS) platform, leveraging wafer-scale manufacturing. Silicon photodiodes, at the core of CMOS image sensors, are perfectly suited to replicate human vision. Thin-film absorbers are an alternative family of photoactive materials, distinguished by the layer thickness comparable with or smaller than the wavelength of interest. They allow design of imagers with functionalities beyond Si-based sensors, such as transparency or detectivity at wavelengths above Si cutoff (e.g., short-wave infrared). Thin-film image sensors are an emerging device category. While intensive research is ongoing to achieve sufficient performance of thin-film photodetectors, to our best knowledge, there have been few complete studies on their integration into advanced systems. In this paper, we will describe several types of image sensors being developed at imec, based on organic, quantum dot, and perovskite photodiode and show their figures of merit. We also discuss the methodology for selecting the most appropriate sensor architecture (integration with thin-film transistor or CMOS). Application examples based on imec proof-of-concept sensors are demonstrated to showcase emerging use cases.

Published: March 2023

Although a variety of patient safety interventions have been implemented, prioritizing them in a limited resource environment is important. The intervention priorities of patient safety managers may differ from those of patient safety experts. This study aimed to clarify the difference in prioritization of interventions between experts and safety managers to better identify interventions that should be promoted in Japan. We performed a secondary data analysis of two surveys: the Delphi survey for Japanese experts and a nationwide questionnaire survey for safety managers in hospitals. Regarding the 32 interventions constituting 14 organizational-level and 18 clinical-level interventions examined in the previous studies, we assessed three correlations to examine the difference in prioritization between experts and safety managers: correlations between experts and safety managers in the three perspectives (contribution, dissemination, and priority), those between priorities of experts and safety managers at the clinical and organizational level, and those among the three perspectives in experts and safety managers. Contribution (r = 0.768) and dissemination (r = 0.689) of patient safety interventions evaluated by experts and safety managers were positively correlated, but priorities were not. Interventions with priorities that differed between experts and safety managers were identified. In experts, there was no significant correlation between contribution and priority or between dissemination and priority. For safety managers, contributions (r = 0.812) and dissemination (r = 0.691) were positively correlated with priority. Our results suggest that patient safety managers evaluated future priority based on past contributions and current dissemination, whereas experts evaluated future priority based on other factors, such as expected impacts in the future, as mentioned in the previous study. In health policymaking, promotion of patient safety interventions that were given high priority by experts, but low priority by safety managers, should be considered with possible incentives.

Authors: Póvoas Susana , Krustrup Peter , Castagna Carlo
Published: March 2023

We aimed at examining the criterion validity and sensitivity of heart-rate recovery (HRRec) in profiling cardiorespiratory fitness in male recreational football players in the untrained and trained status, using endurance field-tests. Thirty-two male untrained subjects (age 40 ± 6 years, VO2max 41.7 ± 5.7 ml·kg-1·min-1, body mass 82.7 ± 9.8 kg, stature 173.3 ± 7.4 cm) participated in a 12-week (2‒3 sessions per week) recreational football intervention and were tested pre- and post-intervention (i.e. untrained and trained status). The participants performed three intermittent field tests for aerobic performance assessment, namely Yo-Yo intermittent endurance level 1 (YYIE1) and level 2 (YYIE2) tests, and Yo-Yo intermittent recovery level 1 (YYIR1) test. VO2max was assessed by performing a progressive maximal treadmill test (TT) and maximal HR (HRmax) determined as the maximal value across the testing conditions (i.e., Yo-Yo intermittent tests or TT). HRRec was calculated as the difference between Yo-Yo tests’ HRpeak or HRmax and HR at 30 s (HR30), 60 s (HR60) and 120 s (HR120) and considered as beats·min-1 (absolute) and as % of tests’ HRpeak or HRmax values. Significant post-intervention improvements (p<0.0001) were shown in VO2max (8.6%) and Yo-Yo tests performance (23–35%). Trivial to small (p>0.05) associations were found between VO2max and HRRec (r = -0.05−0.27, p>0.05) across the Yo-Yo tests, and training status either expressed as percentage of HRpeak or HRmax. The results of this study do not support the use of field-test derived HRRec to track cardiorespiratory fitness and training status in adult male recreational football players.
Study on energy rebound effects of China’s industries
Authors: Xu Guangqing , Huang Danze , Chen Xiaoyu , Chen Mengyao
Published: March 2023

From the perspective of generalized technological progress, this study investigates the energy rebound effects on China’s domestic overall and the country’s various industries using 2005–2017 data. The results showed that the rebound effect of the domestic overall is driven mainly by the secondary sector. The domestic overall and high-energy-consuming industries decrease the rebound effects, whereas low-energy-consuming industries increase the rebound effects. As China’s industrial structure does not lean toward high-energy-consuming industries, this implies that the Industrial Restructuring Initiative that began in the Chinese government’s “Eleventh Five-Year Plan” has effectively slowed down the rebound effects of high-energy-consuming industries, and the feedback effect of self-reinforcement within the economic system was offset. The results also implied that energy efficiency policies should shift to low-energy-consuming industries; the rebound effects of the energy industries could be lessened, the energy efficiency of low-energy-consuming industries could be increased, and the industrial structure could be further optimized by implementing an appropriate pricing in electricity.
Professional perceptions of participatory practices in green stormwater infrastructure development
Authors: Adib Mahsa , Wu Hong , Flohr Travis
Published: March 2023

Participatory practices are essential for green stormwater infrastructure (GSI) development that addresses stormwater issues while providing other ecosystem benefits. However, few studies have examined barriers to community engagement experienced by GSI professionals, particularly which phases include public participation, the groups they target, and the engagement mechanisms selected. If and how professionals evaluated their engagement processes or outcomes also remain under-investigated. This study fills these critical gaps through a survey (n = 195) and key informant interviews (n = 17) of professionals and academics previously involved in GSI development. We reveal that engagement initiatives for GSI are hindered mainly by available resources, knowledge and perceptions, requirements, and the COVID-19 Pandemic. Public hearings/information sessions and design workshops/charrettes are the most frequently applied engagement mechanisms, and current participation practices focus primarily on early project stages. While most of the reported benefits, challenges, and best practices are aligned with well-recognized general community engagement guides, GSI community engagement is uniquely challenged by project technical complexity and the need for effective knowledge transfer and long-term stewardship. Finally, the significant gap in engagement assessments calls for allocating adequate resources for evaluation and advancing research on appropriate evaluative methods based on project type, community context, and evaluation purpose.

Published: March 2023

In the ongoing fight against poverty and inequality, globalization and sustained economic growth are perceived as key to ending global poverty and achieving the Sustainable Development Goals (SDGs). Sustained economic growth is traditionally seen as leading to increased income, which either directly or indirectly lowers poverty levels. Similarly, as the world becomes more globalized, it is assumed that the increase in trade will be accompanied by good quality jobs in both industry and services and, consequently, increasing income, declining poverty and sustained growth.

O bioma da Mata Atlântica tem sido historicamente afetado pelas queimadas e/ou desmatamento e avanço de atividades antrópicas. Essas práticas humanas alteram a vegetação natural e têm ameaçado áreas protegidas, como Unidades de Conservação, Áreas de Proteção Permanente e Reserva Legal. O presente estudo teve como objetivo fazer uma análise da preservação de áreas protegidas, a ocorrência de focos de calor e uso do solo ocupados por atividades antrópicas nos municípios de Prado e Porto Seguro, localizados na Bahia e que abrigam três Parques Nacionais. A análise teve como base o mapeamento da cobertura e uso do solo do projeto Mapbiomas, bem como a presença e densidade de focos de calor dos dados levantados pelo Instituto Nacional de Pesquisas Espaciais entre 2012 e 2020, data inicial de divulgação do novo código florestal. Os resultados demonstraram que os municípios apresentaram aproximadamente 60% do seu território ocupados com atividades antrópicas, incluindo ocupações em áreas de preservação permanente, reserva legal e parques nacionais. Também foram contabilizados, a partir dos anos de 2012 a 2020, 250 focos de calor em Prado e 291 em Porto Seguro. Os resultados evidenciam a necessidade de gestão das áreas afetadas e cumprimento da legislação ambiental para preservação.

Published: March 2023

O sudeste do Tocantins caracteriza-se, dentre outros aspectos geográficos, pela presença de um carste bem desenvolvido, o que motivou a realização da compartimentação geomorfológica do relevo cárstico localizado nos municípios de Natividade e Chapada da Natividade. Neste sentido, este artigo objetivou tecer considerações sobre a influência dos fatores endógenos e exógenos na configuração da paisagem, enquanto eram definidas cada porção do relevo. Para tanto, com o auxílio das imagens dos satélites ALOS/Palsar, Sentinel 2A e da carta topográfica (SC.23-Y-C-IV), foram feitos mapas da rede de drenagem local, de altimetria, declividade, assim como a confecção de perfis topográficos e bloco diagrama, para melhor detalhamento do exocarste. In loco, o software Avenza Maps e os pontos espacializados no Google Earth Pro tornaram a navegação rápida e objetiva. A partir de então, dividiu-se a área em três compartimentos: Compartimento dos Planaltos Metassedimentares Não-Carbonáticos (PMNC), Compartimento dos Planaltos Carbonáticos (CPC) e Superfícies com Ocorrência de Dolinas (SCOD). O trabalho resultou ainda na elaboração de um mapa exploratório de fenômenos cársticos em escala de semidetalhe (1:50.000). O trabalho pode contribuir para a elaboração de políticas ambientais e servir de referência às novas pesquisas, auxiliando na produção de conhecimento mais detalhado do carste da região estudada.

Published: March 2023

O objetivo central deste trabalho foi compreender a (re)produção do espaço urbano e o processo de segregação socioespacial em Poços de Caldas (MG). Ao longo do tempo, Poços de Caldas alterou suas formas, funções e estrutura urbana. A partir do duplo processo de urbanização-industrialização, seu espaço intra-urbano passou por diversas transformações. Essa reestruturação da cidade ocorrida após a década de 1970 intensificou o processo de segregação socioespacial. A cidade tornou-se fortemente dispersa e fragmentada devido às implantações de programas de habitação em áreas distantes do centro e descontínuas do tecido urbano geral, e pelas implantações de espaços residenciais fechados nas periferias.

The drainage system of a hydrographic basin is formed by integrated functional systems, which provide ideal conditions for studies aimed at conserving and preserving ecosystems. Given the need to protect remnants of native vegetation in the Atlantic Forest, this study identified the terrain systems of Una River Basin (BHRU), Bahia, through the technical application of terrain assessment and multi-criteria methodological approach. In addition, the identified systems were evaluated for their levels of potential and emerging frailty. The results showed that the BHRU is subdivided into 8 (eight) terrain systems. Considering the relationship between the natural dynamics of the environment and the pressures exerted by anthropogenic activities, it was found that alluvial and coastal systems have areas with high degree of emerging fragility (8.20% of the BHRU). This high degree of emerging fragility is due to its natural characteristics, allied to the increase of anthropized environments that contrast the Buerarema and pre-coast systems, which have more excellent environmental protection due to extensive vegetation cover on their slopes. The study's methodology was shown to be adequate for the identification and characterization of terrain systems in the BHRU and can be replicated in other ecoregions in the country.

Diversas cidades sofrem com a expansão urbana desordenada, favorecida por ocupações humanas espontâneas que geralmente contribuem para a degradação ambiental. Esta pesquisa objetivou identificar e analisar as dinâmicas espacial e temporal das mudanças de uso e cobertura do solo, entre 1987 e 2018, na microbacia de um igarapé na Amazônia brasileira. Para isso, o método incluiu técnicas de processamento digital de imagens de sensoriamento remoto, bem como visita in loco a pontos estratégicos do curso principal do igarapé, classificação supervisionada pelo algoritmo Máxima Verossimilhança e imagens dos satélites Landsat 5 TM e Landsat 8 OLI. Os resultados mostram a perda da vegetação densa e o aumento considerável das áreas edificadas ou com solo exposto. Nesse sentido, conclui-se que o ambiente sofreu profunda intervenção humana nos últimos 31 anos, sem qualquer tipo de reparação da vegetação nativa.

A bacia hidrográfica do rio das Rãs localiza-se no semiárido baiano, no contexto transicional entre os biomas Caatinga e Cerrado. Compreende uma síntese dos aspectos regionais, ambientais e atuações antrópicas do semiárido baiano. Ao longo das últimas décadas a bacia foi submetida a uma série de pressões antrópicas, levando-a a uma perda expressiva de vegetativo natural. Nesse contexto, o objetivo da pesquisa foi analisar a dinâmica espaço-temporal da cobertura vegetal em tipos de vegetação de Cerrado e Caatinga, da bacia hidrográfica e seu entorno, entre as os anos de 1970 e 2019. Para compreender a dinâmica da cobertura vegetal, no espaço e tempo, fez-se o uso das técnicas do sensoriamento remoto e do geoprocessamento. Nesse período, a redução da cobertura vegetal foi de 360.684,97 ha (18% da área do estudo), sendo que os primeiros 14 anos registraram as maiores diminuições. Os maiores remanescentes de vegetação localizam-se em áreas remotas (afloramentos rochosos/relevos residuais). Observou-se redução significativa da vegetação em áreas de Cerrado e Caatinga, ultrapassando a capacidade dessas fitofisionomias em suportarem pressões antrópicas. O que proporcionou a alteração do uso da terra foi, principalmente, os períodos prósperos da agricultura regional (plantio de algodão) e a prática do carvoejamento ilegal.

A vulnerabilidade natural identifica o maior ou menor estágio de estabilidade ou instabilidade dos elementos abióticos e bióticos da paisagem, enquanto a vulnerabilidade ambiental refere-se à maior ou menor susceptibilidade de um ambiente a um impacto potencial provocado pelo uso. O objetivo deste trabalho é avaliar a vulnerabilidade natural e ambiental na bacia hidrográfica do rio Sepotuba, visando a geração de subsídios para o planejamento. Por meio das geotecnologias foi efetuada a elaboração de mapas temáticos e quantificação dos atributos da paisagem. Para obtenção da vulnerabilidade natural da bacia de estudo foram combinados os mapas de geologia, geomorfologia, pedologia e declividade em Sistema de Informação Geográfica. Enquanto para a vulnerabilidade ambiental acrescentou-se a combinação o mapa de cobertura vegetal e uso da terra. Verificou-se na bacia predomina na vulnerabilidade natural a classe média (42,69%), logo, a magnitude das pressões antrópicas influencia no grau de vulnerabilidade, tornando os ambientes mais ou menos susceptíveis à degradação ambiental. Quanto a vulnerabilidade ambiental predomina a classe alta (47,87%), decorrente das alterações na paisagem, como a supressão vegetal para o desenvolvimento da agropecuária. Concluiu-se que as atividades antrópicas tornaram os ambientes vulneráveis na Bacia hidrográfica do rio Sepotuba, embora muitos destes sejam prioritários à conservação.

A ocupação do Sudeste Mato-grossense é marcada pela chegada da frente de expansão que avançou sobre territórios indígenas por volta da década de 1930, composta sobretudo por camponeses e garimpeiros. Nas décadas seguintes tem-se a chegada da frente pioneira, construindo infraestruturas e estabelecendo relações propriamente capitalistas de produção, com a transformação da terra em mercadoria, a produção determinada pela lógica de mercado, pelo trabalho assalariado, pelas desapropriações dos camponeses e intensificação da ocupação do território dos povos indígenas, que se encontravam em processos de “criação” de terras indígenas (TIs), que compunham uma pequena parte de seus territórios tradicionais. Essa pesquisa teve por objetivo, através de revisão bibliográfica e uso de geotecnologias, analisar como ocorreu o processo histórico de ocupação de territórios indígenas tradicionais no Sudeste Mato-grossense e como esses processos transformaram o uso e cobertura da terra em áreas circunvizinhas às terras indígenas entre 1998 e 2018. O mapeamento do uso e cobertura da terra foi feito através de imagens do satélite Landsat 8/OLI e Landsat 5/TM. A análise demonstrou que essas áreas se encontram com pouca cobertura vegetal e com grande fragmentação de remanescentes florestais, deixando as terras indígenas isoladas e cercadas em meio a atividade da agropecuária.

Authors: Mirabedini Shivasadat , Musavi Hadis , Makhlough Atieh , Hashemi-Sooteh Mohammad-Bagher , Zargari Mehryar
Published: March 2023

Objectives

Type 2 diabetic Mellitus (T2DM) is the most common systemic and endocrine disease in humans, and diabetic nephropathy is one of the most serious complications of this disorder. The polymorphisms in the apolipoprotein A5 (ApoA5) gene are strongly related to hypertriglyceridemia and are considered a predisposing factor for diabetic nephropathy. The current study proposed to examine the association of APOA5-S19W polymorphism with serum lipids levels in patients with type 2 diabetic nephropathy in Mazandaran province.

Methods

This case-control study was designed to determine the association of APOA5–S19W polymorphism with plasma lipid profile in 161 T2DM patients with nephropathy (DN+), without nephropathy (DN−), and in 58 healthy individuals. Lipid profile values were measured using Pars Azmoun commercial kits. S19W variant, one of the polymorphisms of the APOA5 gene, was determined by PCR–restriction fragment length polymorphism (PCR-RFLP) and Taq1 restriction enzyme.

Results

In comparison between the three groups, DN+ had a higher mean TG than DN− and the control group (p<0.001). The incidence of the G allele in DN+ was not significant compared to groups of DN−. Comparing the relationship between the mean of biochemical variables with CC and CG genotypes showed that the mean level of TG in people with CC genotype was increased compared to people with CG genotype in diabetic patients. However, this increase was not significant (p=0.19).

Conclusions

There was no association between SNP APOA5 S19W and serum lipids in diabetic patients with and without nephropathy.

En México, los responsables de gestionar los residuos sólidos urbanos (RSU) son los gobiernos municipales. Para estas municipalidades no existe un esquema establecido de parámetros que sea de utilidad para estimar la gobernanza ambiental en la gestión de residuos. El estado de Oaxaca es una entidad federativa con un importante rezago en educación y nivel de vida; cuenta con 570 municipios, organizados en ocho regiones. Se propuso como objetivo generar un mapeo que evalúe el estatus de manejo o gestión de los RSU en los municipios de esta entidad federativa, a través de una base de indicadores. Los resultados de la evaluación fueron bajos para el 82% de los municipios, mientras que la región con una evaluación significativa fue el Istmo con 28 puntos. Además, se propuso una línea base de parámetros que estimen la gobernanza ambiental en la gestión de residuos y que sea de utilidad en otros estudios similares.

Glasses of binary systems (Sb2S3-As2S3 and Sb2Te3-As2S3) and ternary sections (containing 10, 20 and 40 mol% of Sb2Te3) belonging to Sb2S3-As2S3-Sb2Te3 system were prepared by rapid quenching method in ice water of their liquid phases. From chemical formulas obtained by using Energy Dispersion Spectroscopy (EDS), average values of Sb2S3-As2S3-Sb2Te3 glasses’ parameters such as coordination number (Z), atomic radius (Rav), atomic number (Zav), atomic molar mass (Mav) and electronegativity (av) were calculated. These parameters were used to explain the formation of the glasses in the Sb2S3-As2S3-Sb2Te3 system by following their evolution as a function of the As2S3 content.

Published: March 2023

Pseudomonas aeruginosa is a Gram‐negative bacterium causing morbidity and mortality in immuno‐compromised humans. It produces a lectin, LecB, that is considered a major virulence factor, however, its impact on the immune system remains incompletely understood. Here we show that LecB binds to endothelial cells in human skin and mice and disrupts the transendothelial passage of leukocytes in vitro. It impairs the migration of dendritic cells into the paracortex of lymph nodes leading to a reduced antigen‐specific T cell response. Under the effect of the lectin, endothelial cells undergo profound cellular changes resulting in endocytosis and degradation of the junctional protein VE‐cadherin, formation of an actin rim, and arrested cell motility. This likely negatively impacts the capacity of endothelial cells to respond to extracellular stimuli and to generate the intercellular gaps for allowing leukocyte diapedesis. A LecB inhibitor can restore dendritic cell migration and T cell activation, underlining the importance of LecB antagonism to reactivate the immune response against P. aeruginosa infection.

Enhancing the Quality of Physical Culture Education: Exploring the Role of Communicative Competence in Physical Culture Teachers
Authors: Vaskov Yurij
Published: March 2023

Background and study aim. Effective communication is crucial for teachers in ensuring a high-quality educational process. This study aims to analyze the communicative competence of physical culture teachers and its contribution to the quality of the educational process in their lessons.

Methodology. The study employs a literature review using sources from the Vernadskyi National Library and Google search system, with 31 sources selected for analysis. The study focuses on the components of communicative competence and the assessment of its levels.

Results. The study finds that the quality of the educational process is closely linked to the teacher's professional skills, with communicative competence being an essential component. The study defines the concepts of communication, pedagogical communication, and outlines the various aspects of communicative competence. It further establishes criteria for evaluating communicative competence and identifies three levels of competence.

Conclusions. The study concludes that a physical culture teacher's communicative competence includes verbal and non-verbal means, such as silence, with non-verbal means further categorized into linguistic, kinetic, extralinguistic, and proxemic. Two groups of communicative skills are identified, with one aimed at resolving communicative tasks and the other providing a high level of communication. This study emphasizes the importance of improving teachers' communicative competence in enhancing the quality of the educational process in physical culture lessons.
Applying Integral Thinking to Music Therapy Education
Authors: DiMaio Lauren , Winter Trish
Published: March 2023

Educating music therapy students is a complex task as a result of laws and regulations, professional biases, and a desire to produce students who will be competent and thoughtful music therapists. The purpose, or outcome, of this article is to outline a curriculum re-design implementing Integral Thinking in Music Therapy (ITMT) as applied to the academic and clinical aspects of two university music therapy training programs in the United States. The history and philosophy of ITMT are explained to give context to this approach. An overview of the innovative curriculum design and teaching resources are included for direct implementation of experiences into the classroom. Recommendations include the uses of ITMT in music therapy education as well as possible limitations to this pedagogical approach.
The Question of Copyright in Music Therapy Practice and Research with Children
Authors: Krüger Viggo , Murphy Kathleen M.
Published: March 2023

This short essay discusses the relationship between ownership of creative works and music therapy. We ask the following question: what do we mean by ownership of stories and songs in music therapy? We answer this question by highlighting examples from music therapy literature. We base the essay on the notion that children may have certain rights concerning their intellectual properties and products made in therapy, but these rights are not always honored. Musical products such as lyrics or narratives made in music therapy are protected by most countries' national copyright laws, and music therapists working with music should pay close attention to the rights of the creator. Music therapy should not be a free zone or grey area where the laws on copyright do not matter. The essay offers suggestions for practitioners and researchers.
The Experience of Authenticity Across Three Music Disciplines; Music Therapy, Music Teaching and Music Performance
Authors: Ørnholt Bøtker Julie , Jacobsen Stine Lindahl
Published: March 2023

Across music disciplines, authenticity has been referred to in various ways. Within music therapy and music teaching, only sparsely has it been discussed focusing on the intrapersonal aspects of authenticity. This study seeks to explore and understand authenticity as experienced and expressed by three music professionals practicing within the areas of music therapy, music teaching, and music performance, the goal being primarily to deepen, enrich, and understand the authenticity experience to possibly benefit professionals and their clients, students, and audiences. Three music professionals holding various professional backgrounds were selected based on their assumed ability to reflect on this rather philosophical topic. Preparatory materials were sent out to participants prior to conducting two semi-structured interviews – 1 solo interview and 1 group interview. The interviews were transcribed and analyzed through a thematic coding analysis revealing four meta themes: 1) paradoxes in language and action, 2) imbalance and inauthenticity, 3) roles, relationships, masks, and 4) the field of authenticity. Findings were discussed with chosen theory synthesizing the experience of authenticity as being associated with several interconnected elements: relationship (with self and others), role (self-chosen and assigned), context (role fits the context), professionalism (having skills needed, letting go of control), and personality (transparent persona).
Music and Mandala
Authors: Abbott Elaine
Published: March 2023

It is recommended that music therapists engage in self-care, supervision, and personal therapy to cope with professional stressors. As a result, it is important that they can determine when one or more are needed. The purpose of this paper is to describe a self-administered, seven-step music and mandala method that can be used to determine those needs. Music therapists’ understanding of the purpose of each step will support successful use of the method. Therefore, the description of each step is accompanied by an explanation of the key concept(s) related to it, and a case example. The desired outcome of participation is for music therapists to increase self-awareness and identify their needs for self-care, supervision, and/or personal therapy.

Semi-empirical models for predicting mode-II bond indicators between FRP and concrete
Authors: Al-Huthaifi Nasser , Haddad Rami H.
Published: March 2023

The bond behaviour between fibre-reinforced polymer (FRP) composites and concrete is a complex problem that is influenced by material properties, joint geometric configuration and the surrounding environment. The three fundamental bond performance indicators of concern are interfacial fracture energy, bond strength and debonding strain. This paper introduces a new semi-empirical model for predicting interfacial fracture energy (Gf) between externally bonded FRP and intact concrete in terms of the most influential material and geometric parameters, namely concrete's compressive strength and maximum aggregate size, stiffness of FRP composites and bond width and length of FRP composites relative to the dimensions of the concrete member. The prediction of Gf helped generate accurate predictions for the other two bond performance indicators. The present model was developed using non-linear regression analysis before validation using almost one-third of the total database consisting of 425 points, collected from credible publications. The accuracy of the present model of Gf outperformed those of well-known literature. The excellent agreement in trend behaviour of the present model with those reported in related literature works postulated further the model's validity. The estimation of debonding strain and bond strength in terms of fracture energy demonstrated superior accuracy over those provided by different relevant literature models.
