Eley, Nolan, Catherine Lavandier, Théodora Psychoyou e Brian F. G. Katz. "Listener perception of changes in historically informed performance of solo baroque music due to room acoustics". Acta Acustica 8 (2024): 6. http://dx.doi.org/10.1051/aacus/2023069.
Testo completoAbstract (sommario):
A listening test was performed to determine whether there were any perceived differences in the playing styles of musicians as a function of the room in which the music was performed. This listening test was part of a larger study aimed at investigating the impact of room acoustics on historically informed performance (HIP) of baroque music which included an objective analysis framework designed to capture dimensions of performance important to a historical baroque playing style. The test included both flute and viol examples and included the participation of 20 musically trained listeners with a background in HIP. The results of the test showed some significant differences in certain performance parameters for both instruments. In particular, the flute examples demonstrated differences that aligned with reports from the flutists about the strategies they used to adapt to the different acoustics, and there was agreement between listener ratings and previously extracted objective parameters. These findings suggest that room acoustics play a role in shaping musical performance, and that the resulting changes can be perceived by listeners.

Testo completoAbstract (sommario):
Beatles tributes come in many forms and guises, but look-alikes are arguably the most popular type. Because of their focus on replicating the band’s iconic costumes and hairdo, they usually limit themselves to an easily reproducible core repertoire, forgoing the elaborate post-1966 studio productions. By contrast, sound-alikes strive for complete aural accurateness, often recreating the heavily produced compositions the Beatles never performed outside of the studio. One of the industry’s top-tier Beatles sound-alikes are the Analogues. Neglecting all mimetic visual effects, they re-animate the albums created after 1966, using the same orchestrations and instrumentations as the Beatles, including rare vintage instruments such as the Mellotron. Their approach bears parallels to historically informed performance (HIP), a common practice in Early Music, yet it operates within an entirely different framework. Informed by sound recordings, the Analogues deconstruct and re-record the Beatles’ music to construct their own performance, in the process conceiving a modern technology-based type of HIP. This article begins by establishing a typology of Beatles tributes before examining the process of staging an Analogues performance. It argues that the Analogues’ approach to historical recreation allows them to transcend criticism typically aimed at tributes and, paradoxically, lay claim to an “authentic” performance of what is inherently inauthentic, a live imitation of a recording. Overall, this article demonstrates how HIP can be used effectively outside of its mainstream classical context as a tool for popular music researchers and performers.

AbstractThis article explores an emergent vanguard of the ‘historically informed performance’ (HIP) movement in the twenty-first century, focusing on new music written for, and performed on, historical instruments. Drawing on musicological and journalistic writing, as well as first-hand interviews with artists working in the scene, discussion is centred around the work of three key practitioners: the lutenist Jozef van Wissem, gambist Liam Byrne and baroque violinist Halla Steinunn Stefánsdóttir. Finally, an attempt is made to situate the scene, both in relation to earlier revivalist practice and to broader cultural trends, drawing, in particular, on notions of ‘retromania’, post-internet and post-postmodernist practice.

Testo completoAbstract (sommario):
In the 20th century a wave of experimentation and discussion hit most artistic disciplines. As pianist-researcher Mine Dogantan-Dack points out, classical music has been slow to join in. Although composers have been experimenting with the musical language, classical music performance as an artistic practice has relatively stayed untouched. In the area of vocal music, the traditional recital format with the singer standing by the piano is THE standard. In my doctoral research project, I aim to challenge and explore alternatives to this traditional format. I start by investigating the original performance practice of Satie’s mélodies to then design three different performances of this repertoire using various artistic methods and theoretic concepts. The first one is based on the approach known as historical informed performance (HIP). Satie’s mélodies are little known and seldom performed. They are also difficult to appreciate at a first hearing: incredibly short, condensed in their simplicity, lacking catchy melodies and with obscure texts. My hypothesis is that the standard way of performing them, as a static vocal chamber music recital, doesn’t suit them and makes it in fact harder for the public to appreciate them. Investigating the original performance practice then became a way to rediscover other aspects of the music, beyond the dogmas of the score, and to find inspiration for creating alternative modes of presenting classical vocal chamber music. In this paper I retrace my use of HIP as a creative tool for designing performances of classical music.

This study investigates the essential strategies for interpreting Johann Sebastian Bach's Cello Suite No. 1 Prelude, with a specific emphasis on historically informed performance practices (HIP). The focus of this study is the intricate implementation of Baroque performance methods, including slurs, detached notes, double stops, cross-string techniques, and ornamentation. These skills are crucial for providing a faithful interpretation of Bach's music. The significance of this research is to connect historical performance techniques with present interpretative approaches, guaranteeing that contemporary performers may give performances that are both historically precise and emotionally captivating. The research methodology employed in this study involves an extensive examination of relevant literature, specifically focusing on the contributions of prominent academics such as Frederick Neumann, David Schulenberg, and Jean Claude Veilhan. These scholars have offered valuable insights into the fundamental aspects of Baroque performance practices. Furthermore, this analysis examines the incorporation of historical knowledge with contemporary performance practices by studying the practical insights of esteemed cellists such as Anner Bylsma and Pieter Wispelwey. This dual approach enables a comprehensive comprehension of both the theoretical foundations and actual implementations of the performance strategies in question. This research emphasizes the crucial function of slurs in producing smooth and connected phrasing, the significance of detached notes for precise rhythm, the utilization of double stops and cross-string techniques to enhance harmonic richness and technical complexity, and the importance of ornamentation in deepening the expressive quality of the Prelude. This research offers a complete framework for interpreting Bach's Cello Suite No. 1 Prelude by combining theoretical analysis with practical performance suggestions. This technique not only respects the artistic authenticity of Baroque music but also guarantees that Bach's enduring masterpiece remains relevant to contemporary audiences, thus contributing to the continuous development of classical music performance.

Testo completoAbstract (sommario):
In the world of historically informed performance (HIP) the word ‘authenticity’ is, if not exactly dead, certainly taboo (‘I know that we shouldn't use the A-word’), fenced in with qualifiers (‘Of course we can't be fully authentic’) or softened to clarify that of course HIP performances are aiming for something less than a full realization of the composer's intentions (‘This may be the way Mozart could have heard it’, or ‘This represents some of the practices of the time’). But at least for the most successful practitioners of HIP (epigones may be a different matter), authenticity discourse was always a significant but simplified version of one part of a more complex and even contradictory set of justifications for using old instruments and techniques. Indeed, HIP practitioners regularly invoke chapter and verse from the treatises or other primary sources in the same breath as claiming not to be interested in authenticity per se or not to be engaged in any kind of ‘reconstruction’. This discursive rupture may be more striking with music of the later seventeenth, eighteenth and nineteenth centuries, where the performance-practice sources are more numerous and the scores are more ‘complete’ by modern standards than those of much earlier music, whose performance has always been more frankly imaginative and conjectural.

Yiddish and German are two languages and cultures that are considered autonomous and important within the European cultural diversity. Although they are linguistically very close and historically interwoven, not much research has been done concerning the comparison of their folk cultures. The present comparative study of Eastern Yiddish and German folk songs is a first step towards a deeper understanding of the processes of cultural migration and transfer since the Middle Ages. The paper concentrates on three aspects: 1. Discussion of previous undervalued research by scholars in the twentieth century. 2. Uncovering the roots and routes of parallel folk songs. 3. The significance of this research for the development of a historically informed performance practice (hip) for Yiddish folk songs.

A representação do violino como instrumento musical hegemônico é um fato incontestável se considerarmos sua presença nos mais diversos âmbitos das práticas da música ocidental. As últimas décadas presenciaram, porém, a emergência de algumas vozes dissonantes: as práticas interpretativas historicamente informadas (Historically Informed Performance ou HIP) redescobriram o violino barroco e todo o seu aparato técnico; no Brasil, a rabeca mostrou suas potencialidades, não mais somente nas mãos de ardorosos defensores da cultura popular, mas de músicos em busca de novas sonoridades. Tomando como exemplo a intersecção do popular e erudito contido nas peças para rabeca escritas por José Eduardo Gramani, pretende-se aqui, sobretudo, mais do que apresentar respostas definitivas, abrir novas questões relacionadas ao ensino do violino no mundo contemporâneo, a partir da inserção de instrumentos esquecidos pela história oficial. Neste sentido, reflete alguns dos aspectos defendidos por Walter Benjamin em Sobre o conceito de história, e traz para a pauta das discussões sobre interpretação musical a questão da padronização imposta pela indústria cultural.

У статті актуалізовано проблему інтерпретації музичних творів у підготовці музикантів-виконавців, майбутніх викладачів виконавських дисциплін. Зроблено наголос на феномені історично інформованого виконання (historically informed performance (HIP)). Розкрито його переваги, недоліки та перспективи застосування в освітньому процесі закладів вищої музичної та музично-педагогічної освіти. Мета статті полягає в аналізі феномену історично інформованого виконання взагалі, а також у контексті навчання майбутніх музикантів і майбутніх викладачів музичного виконавства інтерпретувати твори й оцінювати інтерпретацію як педагогічний ресурс професійного навчання, зокрема. Представлено внесок історично інформованого виконання (HIP) щодо розуміння музичної спадщини, її збереження, розповсюдження, а також акцентовано увагу на її обмеженнях і викликах, які зумовлені сучасними чинниками віртуально-естетичного й інформаційно-цифрового середовища. Конкретизовано педагогічний потенціал історично інформованого виконання, через розуміння інтерпретаційної концепції як такої, що сприяє більш інклюзивному та нюансованому сприйняттю історичної музики. Представлено дискусійні погляди щодо впливу зазначеного виду інтерпретації на узагальнене розуміння виконавського контексту через роль звукозаписів і актуальність історичних практик у сучасному виконанні. Серед суперечливих питань визначено тему актуального застосування стародавньої музики, що подається через висвітлення різних поглядів на історичне виконання. Зокрема вказано на опосередкований чинник занепаду цивілізації, оскільки зосереджується увага на відродженні старої музики, а не на створенні нової. У статті також розглядаються практичні проблеми історичного відтворення, як-от вплив виконавського контексту та зміна очікувань слухачів через записи. Підкреслюється важливість критичної оцінки актуальності конкретних історичних практик у сучасному виконанні.

O ainda restrito acesso a partituras e concertos do vasto repertório musical brasileiro dos séculos XVIII e XIX e sua instrumentação estereotipada (quase sempre obras vocais religiosas com acompanhamento orquestral) são obstáculos para sua inclusão nos currículos dos cursos de música no país e sua apreciação por um público mais amplo. Uma alternativa para mudar este quadro é a transcrição de obras desse repertório e adaptação de sua instrumentação para grupos de câmara menores, com exclusão até mesmo da voz na sua instrumentação. Essas transcrições podem proporcionar, de maneira mais eficaz, o contato e a experimentação com as assim-chamadas práticas de performance historicamente informadas (Historically Informed Performance ou HIP), seja a partir da adaptação de referências (auditivas e textuais) já consolidadas na interpretação do repertório europeu, seja a partir da análise de elementos históricos, formais e possíveis figuras de retórica. No presente trabalho, estas questões são abordadas no Recitativo e Aria da cantata acadêmica Heroe, egregio, douto, peregrino (anônimo, Salvador, 1759) para soprano, dois violinos e baixo contínuo, transcrita para um instrumento de cordas orquestral solista (violino, viola, violoncelo ou contrabaixo) e cravo.

Estimating groundwater level (GWL) changes is crucial for the sustainable management of water resources in the face of urbanization and population growth. Existing prediction methods for GWL variations have limitations due to their inability to account for the diverse and irregular patterns of change. This paper introduces an innovative approach to GWL prediction that leverages multisource data and offers a comprehensive analysis of influencing factors. Our methodology goes beyond conventional approaches by incorporating historical GWL data, examining the impacts of precipitation and extraction, as well as considering policy-driven influences, especially in nations like China. The main contribution of this study is the development of a novel hierarchical framework (HGP) for GWL prediction, which progressively integrates correlations among different hierarchical information sources. In our experimental analysis, we make a significant discovery: extraction has a more substantial impact on GWL changes compared to precipitation. Building on this insight, our HGP model demonstrates superior predictive performance when evaluated on real-world datasets. The results show that HGP can increase NSE and R2 scores by 2.8% during the test period compared to the current more accurate deep learning method: ANFIS. This innovative model not only enhances GWL prediction accuracy but also provides valuable insight for effective water resource management. By incorporating multisource data and a novel hierarchical framework, our approach advances the state of the art in GWL prediction, contributing to more sustainable and informed decision making in the context of groundwater resource management.

Managing a complete master list of public health facility data is deemed important in coordinating and planning of health services and achieving better service delivery. The master lists allow stakeholders to share a uniform operational health services data and ensuring availability and reliable data. This will able to support and manage patients clinical data and other health management services such as disease monitoring, facility management and monitoring service performance. However, most health facilities do not have accurate and informed data, this can affect monitoring of infrastructure and services provided. Various facilities have multiple and redundant lists of health data, the lists differ not only in the information they contain but also in the way they are named and identified. Existing studies state that the development of health facility registries store information mostly using conventional two-dimensional table methods or relational databases as in the case at the Health Informatics Center (HIC), Ministry of Health Malaysia. Hence, they faces the challenges in managing the data since it contains diverse data sources, the absence of uniform data standards and the dependence on manual processes and human intervention. To overcome the current problems, a dimensional modeling technique has been developed in an effort to design a Health Facility Data Warehouse. The proposed design of the data warehouse has been verified by the expert and they agrees that it is suitable for HIC to manage information related to health facilities due to its ability to deal with data sources, able to generate strategic information, as well as the ability to obtain a historical view of facility data. This study shows dimensional modeling techniques are effective in analyzing and designing data warehouse and can be a possible method in managing the master list of health facilities in Malaysia as well as other countries.

What follows is a spoken word piece delivered at the Suncoast Music Education Research Symposium in February of 2019 to a group of higher education faculty and doctoral students. It is the intersection of hip hop lyrics and my white privilege, effectively composed as an artistic response to demonstrate the deep knowledge contained within hip hop lyrics and the value gleaned from their critical analyses. The impetus for this piece was my desire to show the conference attendees an alternative to perpetuated and damaging stereotypes about hip hop, a problem which I perceive as the prevalent understanding of hip hop culture and the dominant critique used to oppress this beautiful art form in educational spaces. A caveat about how I chose to sample some of the lyrics is worth mentioning. In some cases, the first-person perspective of the artists, embodied by their use of ‘I’ or ‘we’ in a song, was not appropriate and lyrics were altered to ‘they’ or ‘them’. This choice was to show internal reflection rather than to imply a lived or even co-opted experience by the author. It is important to stress ‘they’ have informed ‘me’. Jvaust as listening to a piece of music would likely be more powerful than studying the score, this piece may best be received by watching the performance.

The story of hip hop in Brazil is one of empowerment among primarily disenfranchised youth of African and mixed racial heritage. Hip hop’s conquest is less a story of ghetto superstars and much more about overall recognition – hip hop as Brazilian culture. Over the years hip hop has grown to embrace ever-widening demographics and identities, mixing styles and (sub)urban geographies across the country. What is perhaps most impressive is the general pride among fans and artists that hip hop is a culture (and not just music) and thus a source of education, belonging and identity. Following legends, such as KRS-One, Afrika Bambaataa and local icons, Nelsão Triunfo and King Nino Brown, upstarts and veterans continue to shout ‘I am hip hop’ as their mantra. This article is a brief overview of historical and contemporary themes in Brazilian hip hop informed by over twenty-five years of anthropological fieldwork in the city of São Paulo, the indisputable centre of hip hop cultural production of Brazil.

Testo completoAbstract (sommario):
Hip-hop competitions are performed across the world. In the recent inclusion in the 2018 Youth Olympic Games, the assessment of hip-hop performance is undertaken by a panel of judges. The purpose of this study was to determine the reliability of different visualisation tools utilised in the assessment of the hip-hop dance movements. Ten dancers performed basic rhythmic hip-hop movements which were captured using a motion capture system and video camera. Humanoid and stick figure animations of the dancers’ movements were created from the motion capture data. Ten judges then assessed 20 dance trials through observation using three different visualisation tools on a computer display, each of which provided different representations of a given hip-hop performance: (1) the actual video of the dancers; (2) an anonymous stick figure animation; (3) an anonymous humanoid animation. Judges were not informed that they were repeating an assessment of the performances across the three visualisation tools. The humanoid animation demonstrated the highest inter-class correlation coefficients among the three methods. Despite the stick figure animation demonstrating moderate to high reliability, both the humanoid animation and the video demonstrated very high reliability in the intra-class correlation coefficient. It is recommended that further research is undertaken exploring the use of humanoid animation as a formative assessment tool in the evaluation of hip-hop dance and the evolution of hip-hop into a respected artistic athletic discipline.

In this bluesy poetic prose, the author engages poetry, personal narrative, and performance to reflect on how hip hop served as a soundtrack for her transition to womanhood in the rural south. She uses lyrics from Killing Me Softly (originated by Roberta Flack in the 70s and repopularized by The Fugees in 1996) and other songs from the 90s to tell stories about growing up, love, loss, depression, and abuse situated within her race, culture, sex, and social class. She muses how the cadences of sound and the words of songs helped her become a writer and feminist. She also reflects on how her formal and informal education has informed and been informed by her relationship to hip hop, which at times has fluctuated from fixation to disillusionment.

Testo completoAbstract (sommario):
Abstract The success of the early music movement raises questions about performing historical works: Should musicians perform on period instruments and try to reconstruct the original style? If a historically “authentic” performance is impossible or undesirable, what should be the goal of the early music movement? I turn to Gadamer to answer these questions by constructing the outlines of a hermeneutics of early music performance. In the first half of the paper, I examine Gadamer’s critique of historical reconstruction and argue that this critique sheds light on mistaken tendencies and misunderstandings within the early music movement, but it does not discredit the movement as such. In the second half of the paper, I attempt to show how Gadamer’s dialogical account of historical consciousness provides a framework for understanding what historically informed performance is seeking to accomplish, as well as its advantage over a Nietzschean approach.

Objective: Total hip arthroplasty (THA) is a widely successful orthopedic procedure offering relief to patients suffering from hip joint disorders. Ceramic bearings, particularly ceramic-on-ceramic (CoC) surfaces, have gained attention for their remarkable tribological properties and biocompatibility. This article discusses the role of ceramic bearings in THA, including their historical background, stability, and potential complications. It explores the advantages of CoC bearings, such as their low wear rates and reduced risk of complications like aseptic loosening and prosthetic joint infections and delves into considerations like ceramic fracture and squeaking phenomena. Materials and methods:This article is based on a rigorous literature search conducted across reputable academic databases, including PubMed, Scopus, Web of Science, and Google Scholar, the succeeding search keywords were applied: “total hip arthroplasty”, “ceramic- on-ceramic”, “total hip arthroplasty dislocation”, “prosthetic joint infections”, “ceramic fractures”, “aseptic loosening”, “squeaking”. Conclusion: Ceramic-on-Ceramic (CoC) bearings, while promising, are not commonly used in primary hip arthroplasty due to cost concerns and surgical precision requirements. However, they are gaining ground for younger, active patients. Technological advancements have reduced the risks of implant fracture. Additionally, noise generation is not associated with an increase incomplication Nevertheless, patients should be informed about these rare risks during the preoperative consent process.

ABSTRACT Objective: To determine the frequency of hip pain in competitive bodybuilders over three different bodybuilding competitions. Methods: This study evaluated bodybuilders recruited from three competitions during the year of 2016. All participants provided their informed consent and the study received IRB approval. Training routine, health condition, level of success on competitions, history of hip pain and physical examination of the hip were evaluated. Results: 113 bodybuilders were evaluated, mean age was 30.5 ± 8.65 years and mean BMI was 25.2 ± 3.65 kg/m2. Mean values for hip flexion, adduction, abduction, internal rotation, external rotation and distance between the knee and the table (FABER distance) were 116 ± 13, 23 ± 8, 71 ± 12, 40 ± 10, 36 ± 9 and 19 ± 4, respectively. Eight (7%) participants presented hip pain within the week prior to examination and only 2 (1,7%) presented with anterior impingement sign. None of the athletes who reported hip pain interrupted their physical training or performance. Conclusion: Symptomatic athletes continued their training program under the presence of hip pain.

Given the ephemeral nature of digital technology, alternative methods of recording hip-hop history must be developed. While I do not agree with dismantling the intergenerational oral tradition altogether, and would advocate for a reawakening of this historical convention as well, archiving hip-hop digital media, in both institutional archives, museums, and libraries as well as in alternative print, Internet, and video mediums, could be its own form of preservation and power in the hip-hop community. It would preserve a legacy of intergenerational cultural and historical inheritance that is currently threatened. It could also add institutional legitimacy and economic independence. Finally, it could promote education and artistic development. My lecture-demonstration featured an eighteen-minute filmed interview with breakdancer Rokafella, as well as a presentation of the larger project, set against the backdrop of a videotaped, commissioned, solo dance performance with Rokafella as well.

Background: To study myocardial performance index in prediabetes in medical staff. To correlate MPI with cardiovascular risk factors.
Methods: After subject selection, informed consent was taken from the cases and controls. Detailed history was taken and physical examination was done which included weight, height, body mass index (BMI), waist circumference, hip circumference, waist-hip ratio (WHR) and blood pressure measurement. After physical examination, biochemistry measurements including fasting blood sugar (FBS), post-meal blood sugar (PMBS), serum total cholesterol (TC), triglyceride (TG), high-density lipoprotein (HDL), low-density lipoprotein (LDL) and very low-density lipoprotein (VLDL) were done. Myocardial performance index (MPI) was calculated by 2D-ECHO.
Results: BMI, male WHR, serum cholesterol, TG, LDL and MPI was significantly higher in cases (prediabetics) as compared to controls while serum HDL was lower in cases as compared to controls, which was non-significant. Out of 50 prediabetics, 32 (64%) had abnormal MPI with p=0.0001. There was no correlation of MPI with cardiovascular risk factors like BMI, WHR and fasting lipid profile.
Conclusion: BMI, male WHR, serum cholesterol, TG, LDL and MPI was significantly higher in cases as compared to controls. However, there was no significant correlation between MPI and other cardiovascular risk factors.

In the late 1980s through 1990s shifts within the aesthetic of hip hop culture helped the sustainability of breaking. When the discussion of hip hop and its major contributors are mentioned, seldom is there any acknowledgement of African American women. Like many art forms, hip hop is male-dominated, which can eclipse narratives about African American women in early hip hop dance circles. African American women practitioners are rarely called upon to moderate panels, write or are acknowledged as true pioneers of the field. Many times, throughout hip hop, African American women kept the dance alive with their resiliency, becoming the catalyst from the streets that help preserve and continue its legacy. The question I ask is: How have these African American women impacted global hip hop culture and why are they unknown to us? The article will examine performance qualities within interdisciplinary practices that forged ahead hip hop culture with these under-represented New York hip hop female dancers. Insights about the experience of these African American female pioneers bring into light historical concerns of exploitation and representation right in time for the introduction of breaking in the 2024 Olympics.

This article offers a new view on ‘period’ or – as we propose to call it – ‘historically informed’ costume. We consider ‘historically informed’ costume a product of a specific mode of creation, but also and especially a process of research, which brings new insights both into the history of costume and performance. After a brief overview of approaches to period costume through the twentieth century, and its use in ‘historically informed performance’, we present a methodology developed through five years of collaboration between costume maker, historian and performers within the research project Performing Premodernity. This methodology employs comparative research of material, visual and textual sources, and making and performing experiments, often in historical spaces. It stresses an experimental and collaborative approach to research and creation, in which each member brings their expertise and way of doing that complement one another. Furthermore, the methodology promotes connections between objects – costumes and bodies – which inform each other through the historicity of their practice.

Popular culture is often othered in conservative theses as inferior and [or because it is] foreign. Scholarship and views on popular music in Nigeria have been sometimes inattentive to the extent that the popular musical forms have gone to entrench themselves as recognizable local forms. This article compares older popular forms that are now canonized—such as jùjú and highlife—with Nigerian Yoruba hip hop to show the peculiar historical factors that justify the latter’s cultural heterodoxy. The dominant hip hop morality that emerged is defiantly divergent from the earlier stress on formal education and legitimate industry. Importantly, hip hop performance in Yoruba has evolved a protocol of social criticism that first presents itself as acquiescent and/or reprobate. Also, existing conceptualization of hip hop acts as hidden [or even public] transcripts is complicated by the novel strategy of mimicry now found in the Yoruba form.

Crowd simulation holds crucial applications in various domains, such as urban planning, architectural design, and traffic arrangement. In recent years, physics-informed machine learning methods have achieved state-of-the-art performance in crowd simulation but fail to model the heterogeneity and multi-modality of human movement comprehensively. In this paper, we propose a social physics-informed diffusion model named SPDiff to mitigate the above gap. SPDiff takes both the interactive and historical information of crowds in the current timeframe to reverse the diffusion process, thereby generating the distribution of pedestrian movement in the subsequent timeframe. Inspired by the well-known social physics model, i.e., Social Force, regarding crowd dynamics, we design a crowd interaction encoder to guide the denoising process and further enhance this module with the equivariant properties of crowd interactions. To mitigate error accumulation in long-term simulations, we propose a multi-frame rollout training algorithm for diffusion modeling. Experiments conducted on two real-world datasets demonstrate the superior performance of SPDiff in terms of both macroscopic and microscopic evaluation metrics.

Purpose The purpose of this paper is to describe the ways in which hip-hop pedagogies and literacies encouraged middle school students to explore performance poetry as a tool to “(w)right” the truth(s) about learning and living in their local and global communities. Design/methodology/approach Collaborative self-study research methodologies were used by the author, a black male teacher educator and hip-hop cultural insider, along with two white, female reading specialists and hip-hop cultural outsiders, to collect and analyze the practices and behaviors used in The Shop – an after-school hip-hop-based spoken word poetry club for middle school students in a small, urban public school district in Northeastern USA. Findings Three primary findings emerge: teachers with limited cultural and content knowledge of hip-hop may struggle to negotiate real and perceived curricular constraints associated with using pedagogies with hip-hop texts and aesthetics in traditional school contexts, the intersections of teachers’ racial, cultural and gender identities informed the respective practices and behaviors in a number of interesting ways, and using hip-hop pedagogies for social justice in public schools requires a delicate balance of both transparency and discretion on the part of teachers. Originality/value Study findings are salient for in- and pre-service English teachers and English educators, as they offer insights and reflections on the instructional and relational challenges cultural outsiders may face when using hip-hop culture to create spaces and opportunities for young people to talk back and speak truth to power.

Background: Total hip arthroplasty is a surgery in which the diseased ball and socket of the hip joint is completely removed and replaced with artificial materials and satisfaction is a state felt by a person who has experienced a performance or an outcome that fulfill his or her expectation. Prevalence of total hip arthroplasty is 5.26%. Objectives: The objective of the study was to determine the patient satisfaction level after primary total hip arthroplasty. Methods: This was a descriptive cross sectional study with a sample size of 51 patients. Both genders are included with an age range of 45-65years and the patients who enrolled six months after surgery. Those patients were excluded who refused to participate in the study, those patients undergoing revision hip arthroplasty and patients who have any congenital deformity of lower limb. A self-administrated patient-satisfaction questionnaire was used. The questionnaire was valid and reliable and used in a previous study. Data was analyzed by using Statistical Package of Social Sciences (SPSS). Value of Cronbach's alpha was 0.86 which was considered highly reliable. Informed consent was obtained from every single patient. Results: Mean age of patients was 55.72, with range minimum 46 years to maximum 65 years. Satisfaction after six months of total hip arthroplasty in patients was somewhat high, 46.1% and the percentage of patients who were dissatisfied was 8.8%. Conclusion: Patient satisfaction is higher after total hip arthroplasty. Patients are satisfied with the result of the surgery, improving pain and improving functional activities.

The performance, field utility, and low cost of lateral flow assays (LFAs) have driven a tremendous shift in global health care practices by enabling diagnostic testing in previously unserved settings. This success has motivated the continued improvement of LFAs through increasingly sophisticated materials and reagents. However, our mechanistic understanding of the underlying processes that drive the informed design of these systems has not received commensurate attention. Here, we review the principles underpinning LFAs and the historical evolution of theory to predict their performance. As this theory is integrated into computational models and becomes testable, the criteria for quantifying performance and validating predictive power are critical. The integration of computational design with LFA development offers a promising and coherent framework to choose from an increasing number of novel materials, techniques, and reagents to deliver the low-cost, high-fidelity assays of the future.

Testo completoAbstract (sommario):
The Steam Generator (SG) is a crucial component of a Nuclear Power Plant (NPP), generating steam to transfer heat from the primary loop to the secondary loop. The control performance of the Steam Generator Level Control System (SGLCS) plays a crucial role in the normal operation of the SG. To improve the system’s performance, the parameters of the control system should be optimized. However, the steam generator and its corresponding control system are highly complex, exhibiting nonlinearity and time-varying properties. Conventional parameter-setting methods mainly rely on engineers’ experience, and are laborious and time-intensive. To tackle the aforementioned challenges, a Model-Free Optimization (MFO) method based on Knowledge-informed Historical Gradient-based Simultaneous Perturbation Stochastic Approximation (GK-SPSA) is applied to the performance optimization of the steam generator level control system. The GK-SPSA algorithm is a variant of the traditional SPSA algorithm. The fundamental idea of this revised algorithm is to maximize the utilization of historical gradient information generated during the optimization process of the SPSA algorithm, with the aim of enhancing overall algorithm performance in a model-free optimization context. Based on the effective utilization of historical gradient information, the GK-SPSA algorithm exhibits two improvements over the SPSA algorithm. The first improvement is related to the recognition of the online optimization progress, utilizing the state of the optimization progress to dynamically adjust the optimization step size. The second improvement is related to gradient estimation compensation, employing compensation rules to enhance the accuracy of gradient estimation, thus improving the optimization efficiency. Through simulation experiments, it can be observed that there is not much difference in the final iteration values among the GK-SPSA, IK-SPSA, and SPSA methods. However, the iteration count of GK-SPSA is reduced by about 20% compared to SPSA and by 11.11% compared to Knowledge-informed SPSA (IK-SPSA). The results indicate that this method can significantly improve the efficiency of parameter tuning for the liquid level control system of a steam generator.

Testo completoAbstract (sommario):
In a rapidly evolving and often volatile crypto market, the ability to use historical data for simulations provides a more realistic assessment of how decentralized finance (DeFi) protocols might perform. This insight is crucial for participants, developers, and investors seeking to make informed decisions. This paper presents a comprehensive study evaluating the dynamic performance of a newly developed DeFi protocol—NOLUS. The main objective of this paper is to present and analyze the built realistic model of the platform. This model could be successfully used to analyze the stability of the platform under different environmental influences by performing various simulations and conducting experiments with different parameters that could not be realized with the real platform. In the article, the key components of the platform are presented in detail and the main dependencies between them are clarified, in addition to the ways of forming multiple variables, and the complex relations between them in the real protocol are explained. The main finding from the experimental part of the study is that the performance of the protocol representation accounts for the expected system behavior. Hence the system simulation could be successfully used to reveal essential protocol behaviors resulting from potential shifts in the crypto market environment and to optimize the protocol’s hyper parameters.

Mutual fund performance depends on many things, including the fund manager's skill. Investors must evaluate a manager's past performance, investment strategy, and market adaptability to make informed investment decisions. Remember that past performance does not guarantee future outcomes, and knowing the fund's strategy and manager's approach is crucial for investing. Mutual fund performance depends on fees. Investors should evaluate a fund's management fees, loads, and other charges to determine their influence on returns. Active vs. passive funds and fee transparency can also affect investment decisions. Fund size affects performance differently depending on kind and market. Larger funds may face style drift, liquidity concerns, and operational hazards notwithstanding economies of scale. Investors should carefully analyse a fund's characteristics, investment approach, and how its size may affect its goals. Mutual fund evaluation should also include manager expertise, costs, and historical performance. Investors must examine market dynamics and mutual funds' responses. Making informed investment selections requires understanding the macroeconomic climate, global events, and a fund's capacity to traverse changing market conditions. Investors should also match their investing goals and risk tolerance with the funds they buy, considering more than previous performance.The main goal of the research is toidentify &analyse factors which influence mutual fund performance in the context of manager Skill, fees, fund size, and market conditions.

Testo completoAbstract (sommario):
Accurate prediction of mutual fund performance is becoming crucial for investors and fund managers to make informed investment decisions and earn profits. This paper utilized Long Short-Term Memory (LSTM) models to forecast the future performance of mutual funds in this research paper. This paper began by collecting a comprehensive dataset comprising historical fund prices and relevant financial indicators from Yahoo Finance. The dataset is preprocessed to handle missing values and format errors. LSTM models are known for their ability to retain and utilize information from earlier time steps in a sequence to make predictions or decisions at later time steps. This capability enables them to capture and understand long-term dependencies or relationships between elements in the sequential data, which are employed to understand and model the changes and trends in the performance of a mutual fund over time. The models are trained on a subset of the dataset, and hyperparameters are optimized to enhance their predictive capabilities. Evaluation metrics such as Mean Squared Error (MSE), the mean absolute error (MAE), root mean square error (RMSE), and R2 are employed to evaluate how accurately the models can predict future outcomes or events based on the available data. In conclusion, this research presents a robust methodology for predicting mutual fund performance using LSTM models. The findings highlight the potential of LSTM models as valuable tools for fund managers and investors, offering enhanced accuracy and providing valuable insights for informed decision-making in the dynamic and competitive mutual fund market.

AbstractIn this essay, I explore the use of rap and hip-hop conventions as they have developed within the self-consciously contemporary American Jewish ‘hipster’ scene between c. 1986 and 2006, framed particularly around the way these genres have addressed the discourses of masculinity within Jewish culture. By exploring the works and actions of such artists as Matisyahu and the Hip Hop Hoodíos within the context of both American Jewish masculinity discussions and the historical relationship of Jews with commercial hip-hop performance, I attempt to explore how a population’s attempts at musical ‘change’ act as a crucial part of the religious and ethnic transmission and preservation process. Although outwardly seen as based on mimesis and even novelty, ‘Jewish’ hip hop, I suggest, instils a deep sense of identity into a population often characterised as iconoclastic, dynamic, politically inclusive and culturally mutable. Masculinity therefore serves largely as a vessel for young Jews to fashion a sense of self into a conversation from which they had previously been largely absent: one of several strategies used both to unmoor and to redefine what it means to be a ‘new’ Jew.

Purpose This paper aims to examine tensions around play, performance and artmaking as becoming in the mix of expected and taken-for-granted discourses implicit in an after-school ceramics makerspace (Perry and Medina, 2011). The authors look closely at one adolescent girl’s embodied performance to see how it ruptures the scripts for compliant bodies in the after-school program. While these performances take place out-of-school and in an arts studio, the tensions and explorations also resonate with broader issues around student embodied, performative and becomings that run counter to normalized school expectations. Design/methodology/approach A contemporary approach to nexus analysis (Medina and Wohlwend, 2014; Wohlwend, 2021) unpacked two critical performative encounters (Medina and Perry, 2011) using concepts of historical bodies (Scollon and Scollon, 2004) informed by sociomaterial thing-power (Bennett, 2010). Findings Playing while painting pottery collides and converges with the tacitly desired and expected ways of embodying student in this after-school artspace. Emily’s outer-space alien persona ruptured expected discourses when her historical body and embodied performances threatened other children. While her embodied performances facilitated her becoming a fully present participant in the studio, she fractured the line between play and reality in violent ways. Originality/value As literacy researchers, the authors are in a moment of reckoning where student embodied performances and historical bodies can collide with all-too-real violent threats in daily lives and community locations. Situating these performances in the nexus of embodied literacies, unsanctioned play and thing-power can help educators respond to these moments as ruptures of tacit expectations for girlhoods in school-like spaces.

The agriculture sector plays a crucial role in the economy of Pakistan, contributing significantly to the Gross Domestic Product (GDP) and the employment rate. However, this sector faces challenges such as climate change, water scarcity, and low productivity, which have a direct impact on agricultural commodity prices. Accurate forecasting of commodity prices is essential for farmers, traders, and policymakers to make informed decisions and improve economic outcomes. This paper explores the use of a big data framework for agricultural commodity price forecasting in Pakistan, using a historical dataset on commodity prices in various Pakistani cities from 2007 to 2022 and Apache Spark to preprocess and clean the data. Based on historical spinach prices in Vehari City, the machine learning models Auto-Regressive Moving Average (ARIMA), Random Forest, and Long-Short-Term Memory (LSTM) were applied to price trends, and their performance was compared using Mean Absolute Error (MAE), Mean Squared Error (MSE), Root Mean Squared Error (RMSE) and squared correlation coefficient (R2). LSTM outperformed ARIMA and Random Forest with a higher R2 value of 0.8 and the lowest MAE of 125.29. Such predictions can help farmers to effectively plan crop cultivation and traders to make well-informed decisions.

Speedrunning describes activities related to the development and performance of strategies to complete games quickly, and is a valuable source of historical and technical information, while producing specialized aesthetic explorations of a videogame’s environment. Most research on speedrunning emphasizes its metagaming or documentary function. However, speedrunning also changes the aesthetic experience of gameplay, both for players and in spectated performance. Aesthetic investigation informed by art historical perspectives, such as Angela Ndalianis’ theory of the Neo-Baroque and H.S. Becker’s study of Art World formations, offers new insights into the experience of speedrunning and how discontinuous and disjointed simulated space is experienced and appreciated as aesthetic phenomena by players and spectators. While Nidalianis has applied her theory to videogames, among other types of contemporary entertainment, further investigating speedrunning performances through this lens extends her analysis and problematizes the idea of a videogame as a singular aesthetic work, instead drawing attention to alternative aesthetic experiences videogames can offer.

Countering the historiographic under-representation of Greek modern dance, this article focuses on early twentieth-century dance artist Vassos Kanellos. Combining Western/European choreographic inputs and local, often traditional, elements, Kanellos rearticulated the inscription of Greek dance in historical time—beyond a sole focus on antiquity—and anchored it in a nationally marked space and in the specificity of a posited Greek “race.” Informed by new modernist studies, this article reads Kanellos's practice as a reflection of the country's process of constructing a hegemonic national identity against a background in which Greece constituted both Europe's subaltern periphery and the foundation of its genealogical narrative.

Abstract. Historical centers represent the outcome of transformations and stratifications of the cities across the centuries. The knowledge of a historical urban environment requires an analytical methodology articulated on several interconnected levels of investigation to model a multi-layered complexity that encompasses the geometric and stylistic features of places (blocks irregularities, narrow streets, stratified buildings), the accessibility (pedestrial zone, no flyzone), the use of existing data (GIS, cartographies). Today the challenge for historical centers is dual: on the one side to make use of expeditious technologies to acquire data, on the other one to create 3D city models that allow to manage, visualize, enquire and use these data in a unique digital ecosystem. Our research deals with a multi-sensor data acquisition, evaluation and integration with the aim of creating informed and responsive 3D city models (CIM) that constitute a synthesis of the survey conducted and become the support for simulations in various contexts (seismic risk, hydraulic, energy performance).

This paper presents a systematic methodology for analysing options trading, integrating user inputs with historical stock data to facilitate informed decision-making. The process begins with the collection of user-specified stock tickers and expiration dates, followed by the retrieval of historical price data to assess past stock performance. Key components of the analysis include calculating historical volatility, fetching the option chain, and filtering options into put and call categories. The methodology employs the Black-Scholes model to estimate fair option prices, which are further evaluated by calculating expected returns. The analysis culminates in the ranking of the top three put and call options based on their expected returns, providing users with actionable insights. Additionally, the methodology incorporates visual representations of stock prices and option data, alongside calculations of option Greeks to assess risk sensitivity. This comprehensive approach empowers traders to navigate the complexities of options trading with a clear understanding of potential outcomes and associated risks.

This research explores the impact of social media sentiments on predicting Bitcoin prices using machine learning models, integrating on-chain data, and applying a Multi Modal Fusion Model. Historical crypto market, on-chain, and Twitter data from 2014 to 2022 were used to train models including K-Nearest Neighbors, Logistic Regression, Gaussian Naive Bayes, Support Vector Machine, Extreme Gradient Boosting, and Multi Modal Fusion. Performance was compared with and without Twitter sentiment data which was analysed using the Twitter-roBERTa and VADAR models. Inclusion of sentiment data enhanced model performance, with Twitter-roBERTa-based models achieving an average accuracy score of 0.81. The best performing model was an optimised Multi Modal Fusion model using Twitter-roBERTa, with an accuracy score of 0.90. This research underscores the value of integrating social media sentiment analysis and onchain data in financial forecasting, providing a robust tool for informed decision-making in cryptocurrency trading.

The International Lviv Early Music Festival is one of the largest and most prominent art forums in Ukraine, as well as in Central and Eastern Europe. The program of the festival is based on the current trends of historically informed performance and on the history of early music. It brings together Ukrainian and foreign musicians who have extensive experience in performing on historical instruments and playing music from different eras. Part of the program of each forum represents Ukrainian early music. Since the first festival, the organizers have been striving to present as diverse a program as possible, including not only works of the High Baroque, familiar to Lviv audiences from concerts at the Organ Music Hall and the Philharmonic but also music of the Middle Ages and the Renaissance. Ukrainian early music is mainly represented by the choral church tradition performed by such ensembles as Kalofonia, ACappella Leopolis, Sarmatica, and the Chorea Kozatska, etc. In addition to concerts, the festival hosts academic conferences on the history of music with the participation of prominent Ukrainian and European scholars, as well as roundtables, where festival participants discuss the interpretation of early music and the development of historically informed performance in Ukraine. The festival’s educational program has had a significant impact on professional performance in Lviv.

Testo completoAbstract (sommario):
This essay addresses the challenges of reaching a historically informed understanding of the emotional experience of seventeenth-century musical performance by applying a recent theoretical account of the psychological emotion mechanisms that underpin music perception. A short work by Claudio Monteverdi (1567–1643) is taken as a case study, to investigate the ways that structural elements of the music engage emotion mechanisms. Since modern-day listeners also draw on emotion mechanisms, a modern-day exploration of behavioural responses to the historical work – albeit performed and perceived through different personal experiences and perhaps with different emphases according to the many different social-cultural factors influencing modern perception – enables the identification of which mechanisms are activated in modern perceivers. While the authors acknowledge that emotional responses to music are highly susceptible to a whole range of complex and dynamic socio-cultural experiences and different historical contexts, the research undertaken nonetheless enables the development of some parameters on which to build a modern-day performance that emphasises the mechanisms most likely to arouse affect.

Governments have implemented different interventions and response models to combat the spread of COVID-19. The necessary intensity and frequency of control measures require us to project the number of infected cases. Three short-term forecasting models were proposed to predict the total number of infected cases in Canada for a number of days ahead. The proposed models were evaluated on how their performance degrades with increased forecast horizon, and improves with increased historical data by which to estimate them. For the data analyzed, our results show that 7 to 10 weeks of historical data points are enough to produce good fits for a two-weeks predictive model of infected case numbers with a NRMSE of 1% to 2%. The preferred model is an important quick-deployment tool to support data-informed short-term pandemic related decision-making at all levels of governance.
