目的：本研究欲探究下蹲階段輔以彈性阻力之反向跳預先活動，對於6分鐘恢復時間後之跳躍表現的活化後增益效應。方法：本研究招募11名國立大學體育相關科系男性學生為受試對象，施以2循環、每循環5次的反向跳預先活動，且於下蹲制動階段介入外加彈性阻力，阻力強度分為0% BW、15% BW、30% BW三種情境，並於預先活動介入前與介入後第6分鐘後進行前測與後測。以兩塊測力板擷取前測與後測之反向跳過程中垂直地面反作用力值與時間，並計算發力率、跳躍高度、修正式反應力量指標以及下肢勁度。以相依樣本 t-test 進行統計檢驗，統計水準訂為 α = .05，比較前測與後測的下肢動態力量特徵之參數是否有差異。結果：本研究結果顯示，三種介入模式皆顯著提升反向跳制動末點力值 (p < .05)。15% BW與30% BW的介入模式顯著提升制動期與推蹬期發力率 (p < .05)。30 % BW的介入模式顯著提升反向跳下肢勁度、修正式反應力量指標，並縮短制動期時間 (p < .05)。結論：本研究之介入應有助於增進牽張反射機制之效益，尤其是在離心制動階段的肌力特徵表現上，因此，建議在進行具備牽張反射機制之動作執行前，可透過反向跳下蹲階段輔以30% BW彈性阻力進行下肢動態肌力活化之預先活動，以助於後續之運動表現。

 

Purpose: The current study aimed at exploring the immediate effect of pre-activities of countermovement jumps, with elastic resistance and 6 minutes of recovery time, on post-activation potentiation during squatting phase. Method: Eleven male college students recruited from the Physical Education department at National Dong Hwa University were asked to perform pre-activities of countermovement jumps (2 cycles, 5 repetitions for each cycle), with elastic resistances (0% BW, 15% BW, and 30% BW) during the squatting phase, followed by pre-tests and post-tests before and after six minutes of recovery time. Two AMTI force plates were used to collect data on vertical ground reaction force and time during countermovement jumps for pre- and post-tests. Rate of force development, jump heights, reactive strength index modified, and lower extremity stiffness were calculated accordingly. Dependent sample t-test was conducted (α=.05) to determine if there were significant differences in the parameters related to lower extremity dynamic strength between the pre- and post-tests. Results: Pre-activities with all three interventions significantly increased the ground reaction forces during the breaking phase (p < .05). Pre-activities with elastic resistances of 15% and 30% BW significantly elevated the rates of force development during the breaking and propulsive phases (p < .05). Pre-activities with 30% BW elastic resistance significantly led to increased lower extremity stiffness, reactive strength index modified, and decreased breaking time (p < .05). Conclusion: The added elastic resistance enhanced the benefits of stretch reflex mechanism, especially the muscle strength characteristics during the eccentric breaking phase. Based on our finding, countermovement jumps with pre-activity with elastic resistance of 30% BW is recommended prior to performing movements concerning stretch reflex mechanism.

 
Sensory and physicochemical characteristics of Uruguayan picual olive oil obtained from olives with different ripening indexes
Authors: ELLIS Ana Claudia , VIEITEZ Ignacio , GÁMBARO Adriana
Published: April 2024

The sensory and physicochemical characteristics of olive oil will be mainly influenced by the agronomic conditions of the crop and harvest. Therefore, the results cannot be extrapolated from one region to another. On the contrary, the ripening index (RI) is a factor that can influence the quality of the oils obtained. Picual is one of the four most important olive varieties from Uruguay. This work studied how ripening influences the sensory and physicochemical characteristics of the extra virgin olive oil extracted from the Picual variety olives harvested in Uruguay. A total of 19 samples of olive oils extracted in the Abencor System pilot plant were analyzed. They were obtained from green, medium, and ripened olives from two different harvests (2021 and 2022). All the studied pastes were considered “difficult” due to a high moisture content of over 55%. This was reflected in the low yields of extraction which did not exceed 12.9%. All the oils obtained were characterized as extra virgin from a sensory and physicochemical point of view. Their content of total phenols and oleic acid allows defining Uruguayan Picual oils as “high in total phenols” and “high in oleic acid,” respectively. They were sensory characterized as oils with fruity medium, bitter medium, and pungent medium and green, tomato, banana, and dry fruit aromatic notes. When olives increased ripening, the fruity, bitter, and pungent of the oils and phenol and oleic contents and the oleic/linoleic ratio decreased, and the yield was not modified. This is what makes the Uruguayan olive oil of the Picual variety ideal to be harvested with low RIs.

Published: April 2024

Naucalpan shares critical sustainability challenges with Mexico City due to geographic proximity, notably those related to transport. Furthermore, deindustrialization, lack of integrated urban planning and climate change exacerbate everyday problems in the municipality, including air and water pollution, poor waste management, inequality and poverty. Better understanding the links between these issues could inspire transformative climate action at the local level. A strategic long-term vision for a more sustainable Naucalpan could build upon existing multilevel collaboration agreements and transnational partnerships. Vertical and horizontal integration and formalization of climate change mitigation and adaptation programs and projects could help the municipality to bridge fragmented climate agendas, sectoral development projects and short-term administrations. Naucalpan residents are increasingly recognizing socio-environmental challenges and conflicts at the local level, as well as the shortcomings of the institutionalized channels for citizen participation. As a result, different informal spaces for citizens to voice their opinions regarding government decisions and projects are emerging in the municipality. Addressing significant gaps in municipal data, knowledge and capacity regarding climate change is critical to accelerate a transformation towards sustainability in Naucalpan. Furthermore, existing community-led initiatives could be leveraged to anchor climate action and ensure buy-in from different actors.

Authors: Brandea Bianca
Published: April 2024

Atacul terorist din 11 septembrie 2001 a marcat schimbarea percepției Occidentului asupra Orientului Mijlociu și viceversa. Urmat de prezența militară a SUA în Orientul Mijlociu, acest eveniment a contribuit la dezvoltarea mijloacelor de acțiune teroristă din întreaga lume și la popularizarea jihadului. Atitudinea ostilă a Occidentului astfel succedată a întreținut starea de tensiune dintre cele două spații. De-a lungul timpului, grupărilor jihadiste și teroriste li s-au alăturat membri originari din Occident, care au fost convinși de importanța „misiunilor” pe care și le-au asumat ulterior. În prezenta lucrare, ne vom concentra asupra transpunerii și continuării ostilităților în spațiul geografic și cibernetic, ținând cont inclusiv de conflictul israeliano-palestinian actual.
The integration of multi-domain capabilities in land forces units combined arms operations
Authors: VEREȘ Petru–Marian
Published: April 2024

Current conflicts, ongoing across the globe, have highlighted the need for a new form of warfare that reduces the number of casualties and the degree of destruction and, at the same time, mitigates the effects of hybrid means, ubiquitous in the doctrine of all actors. This new approach to warfare utilizes multi-domain operations as a means of achieving success. Although multi-domain operations have been conducted in the past, the concept that encompasses the process of these operations is novel, and there are still significant adjustments that need to be made to make it operational for all actors. This article aims to study the integration of multi-domain operations into land operations by identifying the strengths and limitations of their development process, the conditions and principles of their integration at the land forces level, resulting from a comparative analysis of US and Russian Federation approaches, as well as from lessons learned from current conflicts.

Application of Molecular Biology Technologies in Environmental restoration
Authors: Zheng Wenyue
Published: April 2024

With the development of molecular biology, various new technologies have been developed and applied to the monitoring and management of the ecological environment. This includes the biodiversity of the oceans, soils, and plant and microbial ecosystems. This paper introduces the types of molecular biology techniques and discusses their applications in bioremediation and monitoring of contaminated environments. Conventional techniques include genetic engineering, DNA sequence analysis, electrophoresis separation and purification, nucleic acid probe detection, and polymerase chain reaction. Denaturing gradient gel electrophoresis (denaturing gradient gel electrophoresis) is a new electrophoresis technique. It is a gel system that separates DNA fragments according to their melting properties. Gene microarray technology (also known as gene chip) began to be widely used in the 1890s with biological monitoring technology. There are thousands of nucleic acid probes, which detect nucleic acids in living organisms using fluorescence or electricity, in gene microarray technology. These technologies can be used to regulate the diversity of microbial communities, solve the virus infection of plants, and explore the contaminant degradation genes and functional strains. The development and progress of modern molecular biology technology and biochemical technology have promoted the research and detection of ecological environments. These methods would become very effective tools for the study of environmental ecology.
Negative Ecological Impacts of Wind Power, Hydropower and Geothermal Energy
Authors: Yang Qianwen
Published: April 2024

With the rapid development of the global economy and increasing population, the demand for energy is growing. Clean energy technology has received a lot of attention in recent years, and it has solved the traditional energy sources such as coal and oil to a great extent, but it still has some negative effects on the environment. This paper obtains data on ecosystems from authoritative websites and published papers in various countries. Use these data to show the changes in the ecological environment before and after the development of clean energy. It has been found that wind power could reduce environmental pollution and water consumption. However, it causes visual interference, noise pollution and negative impacts on wildlife. Hydropower stations generally have comprehensive economic benefits such as flood control, navigation, aquaculture, landscaping and tourism. However, large reservoirs cause extensive inundation upstream of the dam and also affect plant-side aquatic ecosystems. The main environmental problems in the development of geothermal energy are the emission of toxic gases, the overuse of water resources, the negative impact of heavy metals on agriculture and the inefficient use of geothermal energy. In order to minimize the environmental problems associated with the development of various energy sources, it is hoped that the government will support the development of scientific and technological innovations through policies that regulate the development of energy sources.

Published: April 2024

Diabetes especially T2D is one of the most popular chronic diseases all over the world. And the amount of T2D patients is increasing day by day for the gradual changes in diets of people. Unlike T1D, the onset of T2D is not sudden, and because it has relatively few genetic factors, it is easier to prevent or inhibit the onset and complications. Nutritional intervention is not Pharmaceutical but blending and combining the common nutrients to achieve the efficacy, including controlling blood sugar and blood lipids, reduce obesity, etc. And the tangible means are taking specific diet especially Mediterranean diet, adjusting the total energy intake, supplementing specific deficiency nutrients including protein, vitamins, dietary fiber, etc., and quitting harmful eating habits such as drinking high-sugar or alcoholic beverages. The review focused on the several methods of nutritional intervention for diabetes, especially T2D, in different stages, including the prevention and the treatment of both T2D and the complications.

On the International Law Issues of Crimean Public Investment in Russia
Authors: Sun Zeliang
Published: April 2024

On March 16, 2014, Crimea held a referendum to leave Ukraine as part of the Russian Federation. The referendum is a legal procedure used by the people of a region when applying the principle of national self-determination, while the public investment in Crimea involves national sovereignty and territorial integrity. So, when the principle of national self-determination and territorial integrity conflict, does the referendum comply with international law and be recognized? Crimea and public investment in Russia are the case of "foreign self-determination". This paper analyzes the applicable conditions of "foreign self-determination" and the situation of the Crimean people's exercise of the right of national self-determination, and makes specific judgments on the legitimacy of Crimea and public investment in Russia.

Published: April 2024

This study investigates the essential prerequisites for the effective integration of artificial intelligence (AI) into secondary education in the Kingdom of Saudi Arabia, assessing the perceptions of both male and female educators. Employing a descriptive survey methodology, the primary data collection tool consists of questionnaires administered to 427 secondary school teachers in Riyadh. The findings reveal a notable average agreement level (mean score of 4.43) among participants concerning the identified prerequisites for implementing AI. Notably, students' requirements scored the highest (average of 4.51), followed closely by those for teachers (average of 4.48), the educational environment (average of 4.46), and educational content (average of 4.25). Each category demonstrates consistently high importance. Gender-based analysis indicates no statistically significant difference in determining prerequisites, except for those expected from teachers and the educational environment, which garnered preference from female educators. Similarly, no statistically significant variance emerged in the identification of prerequisites based on major. Regarding teaching experience, no statistically significant difference was found in determining prerequisites, except for requirements related to the educational environment, where educators with 10-15 years of experience exhibited a preference. The study concludes that qualification does not significantly impact the determination of prerequisites for AI in secondary education. This study offers useful insights into the perspectives and requirements of educators, providing detailed knowledge of the integration of artificial intelligence (AI) into secondary education in Saudi Arabia. It highlights important factors that need to be considered for the effective deployment of AI in education.

O cultivo de peixes em sistemas de recirculação (RAS) tem se mostrado uma opção promissora para a aquicultura, visando a redução dos impactos ambientais e a otimização da produção. Nesse contexto, este estudo teve como objetivo avaliar a qualidade da água e o desempenho zootécnico de juvenis de tambaqui (Colossoma macropomum) em RAS com água tratada por ozonização e luz UV. O experimento foi conduzido em delineamento inteiramente casualizado (DIC), com três tratamentos (T1 = UV, T2 = Ozônio, T3 = Controle) e quatro repetições. Os peixes foram submetidos a um período experimental de 45 dias, com monitoramento diário dos parâmetros físico-químicos da água e biometrias realizadas no início e no final do experimento. Os resultados mostraram todos os parâmetros de qualidade da água ficaram dentro do intervalo indicado para a criação do tambaqui. Quanto ao desempenho zootécnico, não foram observadas mortalidades ou qualquer diferença estatística significativa entre os tratamentos (P > 0,05). Com base nos resultados apresentados é possível afirmar que o uso do ozônio e da radiação UV não apresenta riscos zootécnicos ou alterações significativamente negativas da qualidade da água durante a criação de tambaqui em sistema RAS. Recomenda-se estudos posteriores com demais classes de peso e por um tempo mais prolongado a fim de validar os resultados alcançados.

Published: April 2024

O aumento da população em situação de rua no estado de Santa Catarina, após a pandemia de Covid-19, sugere uma reflexão sobre as atuais políticas públicas destinadas a este segmento social. A concreção da dignidade humana pode ser analisada por meio da abordagem das capacidades proposta pelo economista indiano Amartya Sen. A teoria sugere uma compreensão da dignidade que envolve as capacidades como oportunidades que o indivíduo terá acesso e suas habilidades de exercê-las para realização pessoal. O método utilizado foi o hipotético-dedutivo, partindo-se da hipótese que as atuais políticas públicas concretizam a dignidade da pessoa humana em situação de rua. Como resultado, constatou-se que a deficiência na efetivação da dignidade pelas atuais políticas públicas, isso porque, o Estado não aborda capacidades do indivíduo, mas oferece apenas meios de subsistências insuficientes para emancipação do indivíduo.

Published: April 2024

Face ao aumento das emissões de carbono na atmosfera e a urgente necessidade de busca de alternativas energéticas mais eficientes em todos os setores da cadeia produtiva, este estudo objetivou determinar a eficiência energética de máquinas utilizadas na colheita florestal operando em sistema full tree e sua correlação com a volumetria das florestas e a produtividade das máquinas. Foram analisados dados coletados em áreas de uma empresa florestal, produtora de eucalipto, localizada nas regiões dos vales dos Rios Jequitinhonha e São Francisco, Estado de Minas Gerais. Foi analisado o rendimento energético das máquinas Feller Buncher, Skidder e Garra Traçadora, operando em sistema full tree e sua correlação com a volumetria das florestas e a produtividade das mesmas. Os resultados apontam que a variável produtividade da floresta tem forte correlação positiva a produtividade do Feller Buncher, média correlação positiva com a do Skidder e baixa correlação positiva com a da Garra Traçadora. Seguindo essa tendência, todas as máquinas apresentaram fortíssima correlação negativa entre produtividade e eficiência energética, demonstrando que um acréscimo na produtividade das mesmas acarreta, em ordem inversamente proporcional, uma significativa melhoria da eficiência energética da operação, independente da atividade realizada. Conclui-se a melhoria da eficiência energética em máquinas de colheita florestal oferece vantagens significativas que vão desde a economia de custos e a redução do impacto ambiental até o aumento da produtividade e a conformidade com regulamentações. Portanto, é uma prática importante para o setor florestal moderno, que busca equilibrar o uso sustentável dos recursos naturais com a eficiência operacional.

Published: April 2024

As condições climáticas em especial as variações de demanda atmosférica, condicionam as respostas fisiológicas e o crescimento de espécies florestais. Neste sentido, o presente estudo objetivou investigar a influência dos efeitos conjugados da variação do déficit de pressão de vapor (DPVar) e da temperatura do ar na ecofisiologia de dois morfotipos de Paubrasilia echinata (folíolos pequeno e médio). Buscou-se compreender os mecanismos de aclimatação fisiológica e mensurar o crescimento de ambos os morfotipos em distintas combinações de DPVar e temperatura. Para isso, foram realizados experimentos em casas de vegetação climatizadas, em delineamento inteiramente casualizado. Durante 125 dias, mudas dos dois morfotipos cresceram sob quatro condições atmosféricas de DPVar e temperatura: Baixo déficit de pressão de vapor e baixa temperatura (DPVar↓ + T↓), Baixo déficit de pressão de vapor com alta temperatura (DPVar↓ + T↑), Alto déficit de pressão de vapor e alta temperatura (DPVar↑ + T↑), Alto déficit de pressão de vapor com baixa temperatura (DPVar↑ + T↓). Foram avaliadas as características fisiológicas, relacionadas às trocas gasosas foliares, e o crescimento. Como resultado, as variações climáticas de DPVar e temperatura ocasionaram diferentes mecanismos de aclimatação fisiológica e crescimento nos morfotipos de Paubrasilia echinata. Sob alta demanda e alta temperatura o morfotipo de folíolo pequeno realizou um ajustamento estomático que favoreceu a homeostase das suas relações de carbono e obteve maior crescimento frente as demais condições climáticas, enquanto o morfotipo folíolo médio apresentou um menor ajuste estomático, aparentemente priorizando a manutenção do seu status hídrico e assim apresentou baixa eficiência no uso da água e menor crescimento. Já quando submetidos aos ambientes de baixa temperatura independentemente do DPVar, a estratégia fisiológica do morfotipo médio propiciou o seu maior crescimento. Os morfotipos pequeno e médio apresentam respostas fisiologias e estratégias de aclimatação contrastantes quando submetidos as variações de demanda atmosférica.

Published: April 2024

Este estudo aborda a prática do linchamento, caracterizada como violência extrema por grupos contra indivíduos, um fenômeno histórico e global marcado por camadas de crueldade e desumanização. Analisando especificamente os linchamentos no Brasil, o trabalho destaca a complexidade desses atos, que oscilam entre a desconfiança nas instituições judiciárias e a manifestação de um sentimento coletivo de punição. Através da lente da anomia social de Durkheim, investiga-se a brutalidade dos linchamentos como uma forma de justiça popular profundamente distorcida. O estudo se concentra no caso de Fabiane Maria de Jesus para explorar a relação entre justiça popular e violência, questionando até que ponto a brutalidade dos linchamentos pode ser vista como uma busca por justiça. Adotando uma metodologia dedutiva com análise de conteúdo de notícias online, o objetivo geral é analisar a natureza intrinsecamente cruel dos linchamentos e questionar sua justificação como atos de justiça. Conclui-se que os linchamentos refletem uma falha coletiva em aderir a uma ordem social justa e equitativa, atuando não como justiça legítima, mas como expressões de desespero social e anomia. Os resultados apontam para a urgência de abordagens mais humanizadas de justiça e a necessidade de fortalecer as instituições para restaurar a confiança na justiça formal. Futuras pesquisas são sugeridas para explorar as causas sociais e psicológicas dos linchamentos e desenvolver estratégias de intervenção eficazes.

Published: April 2024

Camponeses e camponesas e suas respectivas organizações sociais fazem a defesa da agroecologia como estratégia de implementar alternativas às consequências deletérias geradas pela agricultura industrial e ao aquecimento global que vem acompanhado de eventos climáticos extremos. O desenvolvimento da agroecologia passa pela construção de processos de Transição Agroecológica (TA) que utilizam diversas metodologias para tal fim. O presente artigo tem como objetivo analisar o uso da metodologia de Camponês a Camponês (MCaC) em experiências aplicadas no Brasil na construção do conhecimento para transição agroecológica, bem como evidenciar a distribuição geográfica da aplicação da metodologia em território nacional segundo critérios metodológicos de busca dos trabalhos em portais e sites de busca de artigos publicados no Brasil. Constatou-se que o MCaC vem sendo aplicado nas regiões nordeste, centro-oeste, sudeste e sul do Brasil em diferentes categorias de publicações acadêmicas. Outra constatação é de que dentre os trabalhos encontrados na literatura sobre CaC destacam-se os trabalhos desenvolvidos na região nordeste. As principais lições destacam o processo de aprendizagem horizontalizada como importante ferramenta de construção do conhecimento agroecológico e da transição agroecológica. E como principais desafios identificados para a massificação dos processos de transição figuram a continuidade das políticas públicas de promoção da agroecologia.

Canis desempenham importante serviço, portanto a gestão ambiental dessa atividade é necessária para minimizar os impactos negativos e atender à legislação, visando qualidade do meio ambiente, vida da população e serviço prestado. O objetivo deste trabalho foi avaliar as medidas de controle ambiental implementadas pelo canil Parque Francisco de Assis (PFA), instalado em Lavras-MG. Realizou-se diagnóstico e avaliação dos aspectos e impactos ambientais antes e depois das medidas de aprimoramento do controle ambiental. O canil apresentou 11 aspectos que podem ocasionar 13 impactos. Os resultados do monitoramento do tratamento da água residuária aplicados na matriz de aspectos e impactos ambientais, após as medidas de controle, apontaram a necessidade de ajustes ainda em relação aos coliformes termotolerantes (E. coli), o que pode ser alcançado com o acréscimo de tratamento terciário. O consumo de água e energia também pode ser mais bem gerido com práticas de reúso do efluente tratado e de uso de água da chuva. As medidas de controle ambiental adotadas pelo PFA se apresentaram como iniciativas essenciais na gestão ambiental da atividade.
Effects of phosphorus and potassium fertilization and fruit canopy position on sugar accumulation in mangifera indica cv. 'Kent' pulp
Authors: Olale Kennedy
Published: April 2024

Sugar content is the key to mango quality and growers are constantly seeking methods to optimize it. In this study, fructose, glucose, sucrose, and maltose sugars were evaluated to determine how phosphorus and potassium fertilizers in varying amounts could affect these sugar levels and how sunlight exposure effects fruit. The experiments were conducted in the KALRO Orchard of Kiambu County, Kenya. Thirty-five healthy 7- to 8-year-old ‘Kent’ trees were selected and divided into five treatment groups with five replicates each. Treatment with 1 kg, 2 kg P, K and combined PK per tree resulted in a significantly higher fructose content than the control.
In contrast, neither 1 kg nor 2 kg P resulted in significantly higher glucose contents than the control. Combined PK fertilizers at 0.5+0.5 kg per tree reduced fructose and increased glucose, sucrose, and maltose. A combination of PK fertilizers at 1.0+1.0 kg significantly increased only fructose, but not other sugars. Even after applying P and K fertilizers, the position of the fruit canopy did not affect fructose, glucose, or maltose contents. However, there was a trend towards a higher sucrose content in fruits exposed to sunlight (5.17 g/100 g) than in canopy fruits (2.29g/100g), although this difference was not statistically significant. The same trend was observed for the other sugars. The t-test revealed no significant differences between the two canopy positions (t = 1.01, p = 0.344). A significant difference in sugar content (p < 0.05) between fruits harvested at different canopy positions suggests that fruits harvested at different canopy positions did not ripen simultaneously.
In contrast, neither 1 kg nor 2 kg of P produced a significant difference in the glucose content. Combining PK fertilizers at 0.5+0.5 kg per tree decreased fructose while increasing glucose, sucrose, and maltose. A combination of PK fertilizers at a rate of 1.0+1.0 kg significantly increased only fructose but not other sugars. Even after the application of P and K fertilizers, the position of the fruit canopy did not affect fructose, glucose, and maltose contents. However, there was a trend towards a higher sucrose content in fruits exposed to sunlight (5.17 g/100 g) than in crown fruits (2.29 g/100 g), although this difference was not statistically significant. The same trend was observed for the other sugars. The t-test revealed no significant differences between the two canopy positions (t = 1.01, p = 0.344).

Corporate governance through the lens of Islam: A comparative review and analysis
Authors: Marjan Usama Ismael
Published: April 2024

Corporate governance is a set of relationship between a company’s boards, its shareholders, and other stakeholders as well as provides the structure and mechanism through which the objectives of the company are set and the means for attaining those objectives and monitoring performance are determined. The concept of corporate governance (CG) has gained critical interest and has become a debating point since the mid-1980s. It became an aspect of concern when the corporate world became aware of the importance of protecting the rights of all stakeholders. This paper critically reviews the existing literature on Islamic Corporate Governance (ICG), presents a basic understanding of Islamic Corporate Governance (ICG) and compares the Islamic concept of Corporate Governance to the Organization for Economic Cooperation and Development principles. The study reveals that the Islamic system of governance encourages and promotes the ethical norms of transparency and honesty in every business transaction.
“Sounds good, but… what is it?” An introduction to outcome measurement from a music therapy perspective
Authors: Spiro Neta , Tsiris Giorgos , Cripps Charlotte
Published: April 2024

“Sounds good, but… what is it?” This is a common reaction to outcome measurement by music therapy practitioners and researchers who are less familiar with its meanings and practices. Given the prevailing evidence-based practice movement, outcome measurement does ‘sound good’. Some practitioners and researchers, however, have a limited or unclear understanding of what outcome measurement includes; particularly with respect to outcome measures and related terminology around their use. Responding to the “what is it?” question, this article provides an introduction to such terminology. It explores what outcome measures are and outlines characteristics related to their forms, uses and selection criteria. While pointing to some debates regarding outcome measurement, including its philosophical underpinnings, this introduction seeks to offer a useful platform for a critical and contextual understanding of the potential use of outcome measures in music therapy.
Social-emotional learning through a drumming intervention
Authors: StGeorge Jennifer , Freeman Emily
Published: April 2024

The growth of social and emotional competence is considered a developmental goal of childhood and adolescence. While early caregiving and family environment are key to children’s wellbeing and developmental trajectories, social-emotional learning (SEL) interventions may reduce young people’s vulnerability to internalising and externalising problem behaviours if family or environment factors present some risk. The purpose of this study was to evaluate the impact of the SEL program DRUMBEAT (Discovering Relationships Using Music, Beliefs, Emotions, Attitudes and Thoughts), a 10-week school-based intervention. Students who took part in the DRUMBEAT program (N = 75, 64% male, 59% Primary School, 18% Indigenous) across six Australian schools, and their teachers, completed pre and post measures of Self-Esteem and the Strengths and Difficulties Questionnaire. Linear mixed model analyses showed there were significant improvements in students’ self-esteem, and internalising and externalising behaviours, as reported by students and teachers. Drumming has the potential to draw young people into an educative environment where rhythm, collaboration and discussion can enhance understanding of intra- and interpersonal processes.
Music interventions and pain: An integrative review and analysis of recent literature
Authors: Fidler Hannah , Miksza Peter
Published: April 2024

Music interventions offer a low-cost, low-risk adjuvant to traditional therapies. However, scarce physiological evidence exists to explain how music relieves pain. In this integrative review, we provide a summary of results in the recent literature regarding music-induced analgesia and provide a critical analysis of methodological patterns. We then describe the need for robust theoretical explanations that could account for the observed effects of music on pain. We completed a broad electronic search using common search engines to identify recent experiments and literature reviews that represented the current understanding of potential causal relationships between music and pain. Thirty-one articles were synthesised in this review – 23 were individual experiments and eight were literature reviews. The results show that music-induced analgesia is a consistently observable phenomenon in clinical settings, although a minority of articles report inconclusive results. The magnitude of pain relief is small to modest and results become less conclusive when derived from indirect measures of pain. Limitations of the recent literature revolve around operational definitions of pain, varieties of pain examined within articles, over-reliance on self-reporting scales, rigour in demographic reporting, diversity and size of samples and weak experimental designs. Theoretical explanations for the effect of music on pain are varied but undeveloped and lacking in physiological evidence. We conclude that music-induced analgesia is a persistently observable phenomenon. To advance the field of study, more rigorous methodological practices need to be applied and more attention needs to be focused on finding underlying physiological mechanisms for the relationships between music and pain.
