Background Problems: With the high demands of sports and the crave for success despite diminishing strength with ageing in the presence of disability, athletes are tempted to contravene the ADRV. Research Objectives: The study aimed to study paralympic athletes’ perspective of doping self-regulatory efficacy in Nigeria. Methods: Descriptive survey design was adopted for the study. A 13-item validated questionnaire (α= .74) was employed to collect data for the study. One-hundred and twenty-four male (81) and female (43) elite para-athletes (mean= 23.15 years, ±3.65) voluntarily participated in the study. ANOVA, PPMC, and Cramer’s V Chi-Square Coefficient Contingency were used to determine the relationship and difference across age, gender and sport type and the extent of the para-athletes’ likelihood to dope and confidence to avoid banned substances, respectively. Findings and Results: It indicated a significant effect of age on likelihood to dope at the p < 0.05 for all conditions (F (1, 123) = 45.84, p = 0.000). Therefore, the null hypothesis was rejected. Findings indicated no significance across gender (0.091, p > 0.05), sport (0.280, p > 0.05), and age (0.263, p > 0.05) on the likelihood to dope. Although, significant among older (0.022), female (0.024) para-athletes. Cramer’s V indicated a strong association when drugs would give immediate fitness (ɸ = 0.217), (ɸ = 0.243), and (ɸ = 0.263) across age, gender, and sport type respectively. Conclusion:  It is concluded among others that the para-athletes showed high self-efficacy and low likelihood to dope even in the presence of stressors. However, the ever-pressing need for the athlete’s body longing need for nutrition, oxygen, rest and staying in shape and top form for competing increased the possibility to use a banned drugs for your injury recovery among some older athletes. Psychological interventions are suggested combat the likelihood to dope given the experience levels or psychological dispositions of athletes.

Published: February 2024

В последние годы возрос спрос на ягодную продукцию. Среди них можно выделить клюкву болотную (Oxyccocus palustris Pers.) и клюкву крупноплодную (Oxyccocus macrocarpus (Aiton) Pers) благодаря их пищевым и лекарственным свойствам. Важной проблемой при выращивании качественных саженцев остается малоизученность системы питания клюквы. Остается слабоизученным вопрос о дозах применения удобрений нового поколения, особенно по фазам развития. Поэтому целью исследования является оценка эффективности удобрений нового поколения на показатели саженцев клюквы сорта «Piligrim». Исследования проводили на территории Главного ботанического сада им. Н.В. Цицина РАН, на контейнерной площадке в лаборатории культурных растений в течение двух лет с 15 апреля по 15 октября (2021-2022 гг). Объектом исследования являлся сорт клюквы крупноплодной «Piligrim». Контрольным являлся вариант без применения удобрений. В качестве удобрений применяли органоминеральные комплексы «Белый Жемчуг» (ГК АгроПлюс) и водорастворимое минеральное удобрение «Fertika Kristalon» (NPK (18:18:18)+Mg+МИКРО). По результатам исследования доказана эффективность удобрения «Агроплюс» при выращивании саженцев клюквы «Piligrim». Выяснилось, что показатели имели максимальные значения: высота куста (15,9 см), число горизонтальных побегов (6,4 шт), суммарная длина горизонтальных побегов (274 см), длина (16,7мм) и ширина (7,6 мм) листа, а также объем корневой системы (13,3 мл).

Published: February 2024

The decline in raw water quality recorded by PDAM Pontianak on Jalan Imam Bonjol is caused by sea water intrusion across land during the dry season. The research objective is to design an IoT-based system as a data transmission medium for monitoring river water quality, the water pH sensor for reading pH levels of water and the Turbidity sensor for reading the level of turbidity in river water and can designing a river water quality monitoring tool using several parameters, namely salinity, pH levels and turbidity. From the overall test results of the tool it can be concluded that the tool has worked. The tool's measurement results can be seen in the Blynk application sent by the tool at an average interval. The results of measurements at 2 locations for 3 days showed that TDS ranged from 2 ppm to 6.16 ppm with an average of 3.8 ppm, turbidity ranged from 211 NTU to 574 NTU with an average of 424.4 NTU and pH ranged from 6.87 to 8.62 with an average -average of 8.02. The tool designed is capable of sending measurement data via the Blynk application to smartphone users.
Amplification in the Uncertainty of the Yield and Recovery for a Steady-State Mineral Separator calculated using the Two-Product Formula
Authors: Iveson Simon , Galvin Kevin
Published: February 2024

This paper presents a simple relationship for estimating the uncertainty in the overall yield and species recovery when the two-product formula is applied to assays of the feed, product and tailings streams of a steady-state mineral separator. The non-linearity of the two-product formula means the reliability of these yield and recovery values can vary significantly. Formal treatment of the problem provides a generalized, albeit complex, expression for the uncertainty (Wills, 1997), limited to relatively small input disturbances. This paper explores the problem further using Monte Carlo simulations, covering the effects of relatively small through to relatively large input disturbances. Assay values for the feed, GF, product, GP, and tailings, GT, were assumed to have the same relative uncertainty. The work focussed on the amplification in the uncertainty of the yield, AY, and recovery, AR, resulting in very simple expressions, AY ~ √2.GF/|GF – GT| and AR ~ √2.GT/|GF – GT|.
Modular Synthesis of Templated Bimetallic Sites in Metal–Organic Framework Pores
Authors: Geary Jackson , Aalto Jonathan P. , Xiao Dianne J.
Published: February 2024

Binuclear metal active sites are found throughout all subfields of catalysis, from homogeneous and heterogeneous systems to enzymes. Here, we report a synthetic route to install well-defined bimetallic sites in metal–organic frameworks that offers independent control over the ligand environment, metal identity, metal–metal distance, active site flexibility, and pore environment. Our approach uses thermolabile tertiary carbamate crosslinkers to template pairs of amine functional groups within framework pores. The templated amine pairs can be quantitatively converted into diverse chelating sites, such as iminopyridine and bis(2-pyridylmethyl)amine ligands, and metalated with a variety of metal cations (M = Mn(II), Fe(II), Co(II), Ni(II), Cu(I), and Cu(II)). A combination of density functional theory, extended X-ray absorption fine structure spectroscopy, and electron paramagnetic resonance spectroscopy is used to confirm the local coordination environment and support the proximal nature of the templated bimetallic sites. The templating strategy described here will enable the exploration of new bimetallic motifs in heterogeneous catalysis.
Essential Dynamics of Ubiquitin in Water and in a Natural Deep Eutectic Solvent
Authors: Gomes Inês , Martins Gabriel , Galamba Nuno
Published: February 2024

Natural deep eutectic solvents (NADESs) comprised of osmolytes are of interest as potential biomolecular (cryo)protectants. However, the way these solvents influence the structure and dynamics of biomolecules as well as the role of water remains poorly understood. We carried out principal component analysis of various secondary structure elements of ubiquitin in water and a betaine:glycerol:water (1:2:;z = 0, 1, 2, 5, 10, 20, 45) NADES, from molecular dynamics trajectories, to gain insight into the protein dynamics as it undergoes a transition from a highly viscous anhydrous to an aqueous environment. A crossover of the protein’s essential dynamics at z ~ 5, induced by solvent-shell coupled fluctuations, is observed, indicating that ubiquitin should (re)fold in the NADES upon water addition at z > ~ 5. Further, in contrast to water, the anhydrous NADES preserves ubiquitin’s essential modes at high temperatures explaining the protein’s enhanced thermal stability.

Published: February 2024

Fluorine-containing saturated nitrogen heterocycles are very attractive structures in medicinal and biological chemistry because fluorine can be used to tune conformation as well as key properties such as basicity and bioavailability. At present cyclic fluorinated amines are accessed using hazardous reagents such as DAST or by lengthy synthesis routes. Here we report a modular two-step synthesis of cyclic β-fluoroalkyl amines using a photoredox-catalysed cyclisation/hydrogen atom transfer reaction of bromodifluoroethylamines.

Unraveling oxidation and spin states of single Fe based meso-macroporous silica catalyst in Fenton like reaction by magnetic measurements
Authors: Bellouard Christine , Kim Sanghoon , Ghanbaja Jaafar , Wojcieszak Robert , Canilho Nadia , Pasc Andreea
Published: February 2024

Single-atom catalysts are acknowledged for their superior efficiency compared to nanoparticles or clusters, primarily because of the enhanced accessibility of the catalytic center. Essential parameters for assessing their performance are the metal loading degree and the oxidation state of the individual catalytic sites. This is particularly the case in Fe-based Fenton like reaction, in which both Fe2+ and Fe3+ are active but react with significantly different catalytic rates. While the elemental metal loading is easily assessed by elemental analysis, the determination of the oxidation degree is more challenging. To do so, we designed single Fe-based meso-macroporous silica materials as catalysts for the degradation of methylene blue, an organic dye serving as well-known model for the degradation of organic pollutants in wastewater. The silica materials were successfully synthesized by a sol-gel process through a combined templating mechanism with micelles and solid lipid nanoparticles of Fe-based surfactants. Magnetic measurements have revealed that half of the iron centers are in the Fe2+ state. The following of the Fenton like reaction through magnetic measurements agrees with a contribution of Fe2+ in the catalytic process. The magnetic response emerges as a valuable tool for quantifying and characterizing individual catalytic centers.

Authors: Andrew Essien  , U. ImaObong
Published: February 2024

The study examined the extent to which principals’ adoption of budgetary control principles (P-ABCP) predict their job performance in public secondary schools in Uyo Local Government Area. The study adopted ex-post facto research design. The population of the study consisted of 41 principals in the 41 private secondary schools in Uyo LGA from which a sample of 21 principals were derived using census sampling approach. Data was collected with designed instruments tagged: “Principals Adoption of Budgetary Control Scale (PABCS)” and “Principals’ Job Performance Scale (PJPS)”. Data collected was analysed using mean while hypothesis was tested with linear regression. The results indicate that the extent of P-ABCP was low (1.88), implying that most of the principals did not utilize feasible budget in administering their schools. The results also showed that the extent to which P-ABCP predicts their job performance in secondary schools was very low. However, though to a very low extent, it was revealed that P-ABCP does significantly predict principals’ job performance. It is concluded the potentials of budgetary control in school administration has shown to be ineffective in enhancing sustainably, the principals’ job performance in public secondary schools. It is recommended that schools owners should mandate the principals to subject their budget and budgetary control plans for assessment before the commencement of an academic session and at the end of the session. This will spur the consciousness of the principals to the importance of having a clear-cut blueprint in the course of achieving effectiveness in school administration.
Monitoring and improvement of PV panel efficiency due to thermal effect
Authors: Anita Manish Soni , Shruti Tiwari
Published: February 2024

Solar Photovoltaic (PV) panels are extensively employed for the purpose of converting renewable energy, namely solar energy, into electrical energy. A significant portion of the solar radiation collected by Photovoltaic (PV) panels is transformed into thermal energy, resulting in the heating of PV cells and a consequent reduction in PV efficiency. The increase in the temperature of Photovoltaic (PV) panels leads to a decrease in their conversion efficiency. The data indicate that an increase of one degree Celsius in PV temperature can lead to a reduction in efficiency of up to 0.65%. This phenomenon has garnered significant scholarly interest in the realm of reducing and managing Photovoltaic (PV) temperature. One of the ways that has been explored is the use of Phase Change Material (PCM), which has the ability to effectively regulate the temperature of Photovoltaic (PV) systems due to its latent heat storing capabilities. Additionally, integrating Phase Change Material (PCM) in Photovoltaic (PV) systems not only helps in temperature regulation but also contributes to extending the lifespan of PV panels by mitigating thermal stress. As the demand for sustainable energy solutions continues to grow, optimizing the efficiency and durability of solar technologies remains a crucial focus for researchers and industry professionals alike.

Abstract
Background: Not a few students deliberately postponed their assignments. Academic procrastination often occurs in students because of the high workload. Self-efficacy is believed to influence procrastination. Objective: This research aims to determine the extent to which students' self-efficacy plays a role in their level of academic procrastination in carrying out lecture assignments. Method: Research uses descriptive quantitative methods with non-experimental research types, and result analysis using simple regression analysis. The subject used is a student of Psychology at the State University of Surabaya. Results: The results of this study showed that self-efficacy and procrastination have a negative relationship, which means that if self-efficacy is improved then procrastination in students is decreased and vice versa. Self-efficacy variables give an effective contribution of 23.2% to the procrastination variable which means self-efficacy is not the most crucial thing in affecting procrastination because there are still 76.8% other factors. Conclusion: To reduce procrastination, self-efficacy is required because the higher the self-efficacy of a person, the lower the tendency to procrastination.

Transformación de los mitos de Cronos y Orfeo en "El hombre y lo divino" de María Zambrano
Authors: López Arano Marina
Published: February 2024

María Zambrano (1904-1991) fue poeta y filósofa, y así lo refleja en El hombre y lo divino, ensayo que invita a regresar a Grecia y recuperar la autenticidad de los ancestros para darnos cuenta de que el hombre no solo tiene una dimensión razonadora, sino que tiene otra dimensión que la razón no alcanza a entener, en este caso espiritual. La poeta y gran pensadora acude a la mitolgía y a los dioses porque sin ellos se produce un vacío existencial y se refugia en diferentes lugares de la mitología griega. El objetivo del trabajo es que a través de los orígenes de los mitos de Cronos y Orfeo se corrobore cómo la instancia de lo sagrado todavía pervive al encontrarse en el subconsciente del individuo, y demostrar que a través de ellos la filósofa intentará buscar en su interior su espacio en la vida y devolverlos al presente.

Published: February 2024

This study examined the impact of foreign direct investment on financial development in selected Arab League countries (Algeria, Comoros, Egypt, Jordan, Kuwait, Lebanon, Mauritania, Oman, and Qatar) for the period from 2010 to 2021. The study used one explanatory variable — financial development — and one explained variable — foreign direct investment. To obtain reliable and valid results, panel data were analyzed, and various tests were carried out, including the Chow test, Breusch-Pagan Lagrange multiplier test, Hausman test, Jarque-Bera normality test, Wooldridge test, generalized least squares, and ordinary least squares. The robust model of the study revealed a positive and significant relationship between foreign direct investment and the financial development index, human development index, and interest rate. Also, there is a negative and significant relationship between foreign direct investment and the consumer price index and domestic credit to private sector. Based on these findings, the study recommends that Arab League countries’ policies and strategies should attract foreign investors to maintain and sustain economic developmental goals for healthy, literate, and wealthy lives.

Published: February 2024

The transformation of the digital economy has been constantly evolving in the society of the 4.0 industrial revolution, particularly under the governmental policies of developed countries. One of the most popular tools in digital economy activities is cryptocurrency, which has led to a rise in digital awareness among people who are more inclined to live their lives electronically and digitally. The aim of this study is to explore the problems and prospects associated with the usage of cryptocurrency and identify ways to address these issues using the governmental roadmap in China and Cambodia. The methods employed in this study include descriptive, explanatory, and comparative analyses. The results demonstrate that the adoption of cryptocurrency presents both opportunities and threats to the Chinese and Cambodian economies. These opportunities and threats need to be carefully considered and balanced by policymakers and stakeholders. The conclusion drawn from the study is that there is still no official acceptance and recognition of cryptocurrency by the Chinese and Cambodian governments. This is primarily due to the fact that the risks and challenges associated with cryptocurrencies are deemed to be greater than the foreseeable opportunities, making them difficult to manage effectively.

Correlates of Cannabis Use and Self-Control Across a Diverse Sample of College Students: 2020-2022
Authors: Giaquinto Francesca , Knapp Jessica , Kulak Jessica , Kamper-DeMarco Kimberly
Published: February 2024

Background: Despite the established relationship between substance use and self-control, it is unknown how the COVID-19 pandemic may have played a role in this association. Given the unique circumstances of the pandemic along with changing societal regulations surrounding cannabis use, and their collective impact on college students, there is a need to examine the relationship between cannabis and self-control during the pandemic era. Methods: Data was collected from a repeated cross-sectional sample of college students at a mid-sized, urban U.S. institution during 2020-2022. Logistic and negative binominal regression analyses along with an ANCOVA were conducted to examine associations between self-control and past 30-day cannabis use. Results: Lower self-control was significantly associated with using cannabis in the past 30-days with those individuals with self-reported low self-control using cannabis significantly more and more times per day. Finally, we found that both past 30-day cannabis use and cohort significantly predicted self-control with both individuals who report past 30-day cannabis use and the 2020 cohort reporting lower levels of self-control. There was not a significant interaction effect. Conclusions: Despite evolving legislation regarding both medicinal and recreational cannabis use, colleges often maintain drug-free campus policies. Given high rates of cannabis use among college students and continued development of self-control, this association should be examined longitudinally and considered when creating college-level cannabis policies. Implications for college students surrounding COVID-era environments, and self-control are discussed.

Old Nordic herðr ‘shoulder’ and Greek κορσίς ‘behind, buttocks, ass’: Is there any etymological relationship between them?
Authors: Kaczyńska Elwira
Published: February 2024

The article discusses a possible relationship between the Proto-Germanic term for ‘shoulder’ (ON. herðr f., Far. herðar f. pl.; Elfd. erde f.; OHG. harti, herti f., MHG. herte f. < PG. *hardīz f.) and the unexplained Greek gloss attested in the lexicon of Hesychius of Alexandria: †κορσίς· πυγή (“korsís: behind, buttocks, ass”). It is suggested that the above-mentioned gloss comes from the Laconian dialect, which already in the Classical era (5th–4th c. BC) spirantized the Greek phoneme θ [th] > [θ] > Lac. σ [s]. The Laconian word κορσίς goes back to the Doric appellative *κορθίς, which presumably derives from the Proto-Indo-European root *ḱerdh- ‘to fart, blow to, break wind’, secondarily ‘to stink, smell’ (cf. Ved. śárdhate ‘s/he breaks wind downwards’; Lat. cerda f. ‘dung’ attested in mūscerdae f. pl. ‘mouse droppings’, ovicerda f. ‘sheep dung’ etc.). The Laconian derivative has reliable semantic equivalents in other Indo-European languages (e.g. Skt. śr̥dhū- f. ‘the anus, rump’, śr̥dhu- m. ‘id.’). The Proto-Germanic term *hardīz (gen. sg. *hardjōz) ‘shoulder’ has no convincing etymology. Its juxtaposition with the Laconian word κορσίς (< Doric Greek *κορθίς < IE. *ḱordh-ī̆-s f.) seems phonologically indisputable. Doubts are raised only by the semantic part of the proposed etymology. The author assumes that ancestors of the Germanic people originally used the term *hardīz (< PIE. *ḱordh-ih2-s f.) to describe an extremely smelly part of the human body, i.e. the armpit located near the shoulder. The suggested change ‘anus, rump’ > ‘a stinking part of the body’ > ‘armpit’ > ‘shoulder’ must have taken place already in the Proto-Germanic epoch.
Taboo zoonyms: What do 'bear', 'lynx' and 'wolf' have in common?
Authors: Wacewicz-Chorosz Adriana
Published: February 2024

The aim of this paper is to trace the etymologies of the English words bear, lynx and wolf and their Polish equivalents niedźwiedź, ryś and wilk within the context of Indo-European languages in terms of the mechanisms for creating euphemisms to denote animals subject to the phenomenon of linguistic tabooization. The methodology comprises the following stages: selection of cognates (to determine the scope of attestation); examination of the semantic features of the selected vocabulary; and an attempt to outline the problem of the functional features of euphemisms to denote tabooed vocabulary. The results of these considerations can contribute to concretising our ideas about the linguistic constitution of the surrounding world by past language users and linguistic interrelationships, as well as help reveal the peculiarities of euphemistic vocabulary conditioned by the functioning of linguistic taboos.
Symptotic behavior of solutions of the inhomogeneous Schrödinger equation on noncompact Riemannian manifolds
Authors: Mazepa E. A. , Ryaboshlikova D. K.
Published: February 2024

The paper studies the behavior of bounded solutions of the inhomogeneous Schrödinger equation on non-compact Riemannian manifolds under a variation of the right side of the equation. Various problems for homogeneous elliptic equations, in particular the Laplace-Beltrami equation and the stationary Schrödinger equation, have been considered by a number of Russian and foreign authors since the second half of the 20th century. In the first part of this paper, an approach to the formulation of boundary value problems based on the introduction of classes of equivalent functions will be developed. The relationship between the solvability of boundary value problems on an arbitrary non-compact Riemannian manifold with variation of inhomogeneity is also established. In the second part of the work, based on the results of the first part, properties of solutions of the inhomogeneous Schrödinger equation on quasi-model manifolds are investigated, and exact conditions for unique solvability of the Dirichlet problem and some other boundary value problems on these manifolds are found.

The purpose of this study is to determine the effect of capital, labor, and resources on the technical efficiency production of SMEs in West Sumatra and to see whether the SMEs production in West Sumatra is technically efficient. The type of data used in this study is panel data for 19 regencies/cities in West Sumatra from 2015 to 2021 using the Stochastic Frontier Analysis (SFA) approach. This research examines production efficiency technically at SMEs in the West Sumatra region. The result of this study indicates that the production factors of capital and resources have a positive and significant effect on the production of SMEs in West Sumatra, while labor has a negative and insignificant effect on the production of SMEs in West Sumatra. The result of the technical efficiency calculation shows that the mean level of technical efficiency of the SMEs production in West Sumatra from 2015 to 2021 is 0.543 or 54.3 percent,  which means that production in SMEs is technically inefficient. This research implies that the government can compile regulations and road maps that can increase the productivity of SMEs in the West Sumatra region, and for SMEs to be able to engage more broadly with sustainable programs for production efficiency such as attending training and business guidance, using the rural business credit program from the government, as well as establishing cooperation partners for raw materials with other SMEs.

Prioritizing Narrative Structure in Large-Scale Film-Music Analysis: A Case Study of Dramatic Irony inBarton Fink
Authors: Jarvis Brian Edward
Published: February 2024

In this article, I introduce and outline a graphic technique for large-scale film-music analysis that utilizes the film’s narrative structure as a scaffold on which to conduct musical inquiry. This technique combines Seymour Chatman’s narrative theory with Gustav Freytag’s theory of dramatic structure into a temporal map called a Narrative/Dramatic Structure diagram (NDS diagram) upon which a film’s complete score can be viewed and explored. I analyze Carter Burwell’s complete score to the Coen brothers filmBarton Fink(1991) as a case study and demonstrate its usage of large-scaledramatic ironythat provides focus in an otherwise perplexing narrative.
Extending the Parallel Multiple-Analysis Processor
Authors: Sullivan James
Published: February 2024

This article revisits the issue of perceived meter in rhythmically irregular post-tonal music by way of Danuta Mirka’s (2009) dynamic model of meter. Her model, which is a parallel multiple-analysis processor in the sense of Jackendoff (1991), accounts for rapidly fluctuating sensations of meter in the real-time listening process, while maintaining local regularity as a defining feature of metric processing. I offer two extensions to her model—one concerning the perceptual processing of non-isochronous meter and the other concerning meter in multiple perceptual streams—along with applications to music by Carter, Webern, Barber, Babbitt, Feldman, and Adès.
Metric Modes and Fluid Meter in Mande Drumming Music
Authors: Morford James B. , David Aaron M.
Published: February 2024

This article proposes a model that unites a broad range of performances of Mande drumming music within a single cohesive and fluid sub-beat metric framework. The framework categorizes musical performance in terms of two metric modes, each of which includes a set of metric cycles featuring non-isochronous pulsations. A novel feature of the proposed model that distinguishes it from previous research is that it frames metric non-isochrony in terms of the ranges for pulsation positions within a pulsation cycle. This approach is shown to be especially useful for analyzing and describing mechanisms of metrical change and transformation and for connecting seemingly distinct phenomena and repertoire.
Buffy Sainte-Marie’s Self-Expressive Voice
Authors: Murphy Nancy
Published: February 2024

Buffy Sainte-Marie is a Cree singer-songwriter who emerged in the folk-inspired Greenwich Village coffeehouse scene in the mid-1960s. From her positionality as an Indigenous woman, Sainte-Marie wrote protest music (“activist songs”) on topics including antiwar themes and issues facing Native Americans. Her provocative 1966 activist song “My Country ’Tis of Thy People You’re Dying” is an anthem to decolonization that aims to educate her listeners about acts of genocide against Indigenous communities in the United States and Canada. The song’s lyrics, however, are only one aspect of its significance. In this article, I draw on studies of voice and flexible meter to explore Sainte-Marie’s self-expressive vocal rhetoric in three extant recordings of “My Country ’Tis of Thy People You’re Dying”—two from 1966 and one from 2017. I explore how Sainte-Marie’s flexible hypermeter and vibrato techniques add layers of expressive impact to her performances and help to position Sainte-Marie as an innovator in the singer-songwriter tradition.
Philosophizing Time in Sinitic Opera
Authors: Yu Wang Anna
Published: February 2024

This article grapples with the question: how do huangmei opera and kua-a opera listeners experience formal coherence? Both opera traditions abound with changing phrase lengths that subvert the anticipatory listening strategies familiar to Anglo-American theorists. However, these temporal variabilities do not appear to disturb local listeners’ sense of formal coherence. Instead, ethnographic interviews and musical analyses suggest that the temporal sensibilities of huangmei opera and kua-a opera listeners anchor in the cadence of linguistic sounds and, more broadly, in “timeways”—ideas and practices relating to how a community experiences, measures, and expresses time—that stem from a Dao-centered paradigm of worldmaking. The latter yields a conception of musical time that embraces changeability and the pursuit of auspicious timings.
