Humpback whales (Megaptera novaeangliae) are well known for their complex acoustic communication, which plays a critical role in social interactions and reproduction. Understanding the variability in humpback whale songs is crucial to deciphering their communication strategies and the factors that influence these changes, which may affect reproductive success and population dynamics. While most studies of humpback whale song behavior have focused on annual variation, intra-seasonal changes remain underexplored. This study investigates intra-seasonal song variation in the Colombian Pacific humpback whale population, a unique and diverse breeding stock. We analyzed 37 h of recordings collected during two distinct periods of the 2019 breeding season (July and August–September) in the northern Colombian Pacific. Song repertoires were compared between periods, and the acoustic structure of a common song unit (Unit1) was analyzed using spectrographic cross-correlation. Results revealed a decrease in repertoire diversity over the course of the season, along with an increase in the song rate and the acoustic consistency of Unit1 during the second period. These findings highlight the dynamic nature of humpback whale song production and suggest potential influences of social learning and hormonal modulation. Such insights may be useful for the conservation and monitoring of humpback whale populations in breeding areas. Full article

This paper explores the harmonious integration of Confucian moral values and officially sanctioned love-themed lyrics in music education across Mainland China. It addresses the main research question: What role do officially approved school songs, which embody themes of love related to three key relationships—(1) family and home, (2) teachers and friends, and (3) the Chinese Communist Party (CPC) and the Chinese nation—play in promoting the virtue of love through singing within Mainland China’s music education? By analyzing two sets of officially approved music textbooks for primary school students, consisting of a total of 24 volumes, this study reveals how love-themed lyrics serve as a medium for propagating political ideology while reinforcing traditional Confucian values among the younger generation. The research illustrates how love, as a fundamental virtue, is expressed and reinforced through these songs, highlighting their significance in fostering emotional and ethical development. The findings underscore the role of music education in cultivating a sense of community and national identity, as well as the interconnectedness of personal and collective values in shaping students’ moral frameworks.

This paper addresses the issue of distinguishing commercially played songs from non-music audio in radio broadcasts, where automatic song identification systems are commonly employed for reporting purposes. Service call costs increase because these systems need to remain continuously active, even when music is not being broadcast. Our solution serves as a preliminary filter to determine whether an audio segment constitutes “music” and thus warrants a subsequent service call to an identifier. We collected 139 h of non-consecutive 5 s audio samples from various radio broadcasts, labeling segments from talk shows or advertisements as “non-music”. We implemented multiple data augmentation strategies, including FM-like pre-processing, trained a custom Convolutional Neural Network, and then built a live inference platform capable of continuously monitoring web radio streams. This platform was validated using 1360 newly collected audio samples, evaluating performance on both 5 s chunks and 15 s buffers. The system demonstrated consistently high performance on previously unseen stations, achieving an average accuracy of 96% and a maximum of 98.23%. The intensive pre-processing contributed to these performances with the benefit of making the system inherently suitable for FM radio. This solution has been incorporated into a commercial product currently utilized by Italian clients for royalty calculation and reporting purposes. Full article

Yangzhi jingshui 楊枝淨水 (willow twigs and clean water) are part of one of the most popular rituals used in Chinese Buddhist practices. In order to preserve dental health and eliminate bad odors, the Vinaya texts specify rules on chewing willow twigs as a form of tooth brushing in one’s daily facial washing process. Willow twigs are also frequently employed in Esoteric (mijiao 密教) rituals, where they are accompanied by spells to create intricate ceremonies that have the power to heal illnesses, ward off bad luck, and bring about happiness and tranquility. For the development of this ritual in China, the usage of yangzhi jingshui was not originally connected to any particular deity, but later on, the ritual became primarily linked to Avalokitêśvara (Guanyin, 觀音), who was believed to use them as crucial tools for healing and saving lives. The symbolic meaning of using willow and water has been thoroughly discussed by Master Zhiyi 智顗 (538–597) and then has since developed into the more complete Repentance Practice of Guanyin (Guanyin chanfa 觀音懺法). Using yangzhi jingshui to save people as well as trees is also an important aspect described in Buddhist biographies and Chinese novels, such as Gaoseng zhuan 高僧傳 [The Biographies of Eminent Monks], Song Gaoseng Zhuan 宋高僧傳 [Biographies of Eminent Monks in the Song Dynasty], and stories of collected in Taiping guangji 太平廣記 [Extensive Records of the Taiping (xingguo) Period], Lunhui Xingshi 醒世輪回 [Reincarnation Stories to Awaken the World], and Xiyou ji 西遊記 [Journey to the West], which all demonstrate the rich cultural significance of this ceremony. Through the narratives of monks, the worship of Yangliu Guanyin, and its portrayal in the literature, yangzhi jingshui evolved from a cleansing tool in scriptures to a ritual object in Esoteric Buddhist healing ceremonies, ultimately becoming a common Buddhist practice. While new elements were added over time, its core themes of healing and purification have remained consistent. Full article

To address the issues of high single-point failure risk, weak privacy protection, and poor resistance to poisoning attacks in edge federated learning, an edge federated learning privacy protection scheme based on blockchain and fully homomorphic encryption is proposed. This scheme uses blockchain technology combined with the CKKS (Cheon–Kim–Kim–Song) fully homomorphic encryption scheme to encrypt computational parameters. This approach reduces the risk of privacy leakage and provides edge federated learning with features such as anti-tampering, resistance to single-point failure, and data traceability. In addition, an unsupervised mechanism for identifying model gradient parameter updates is designed. This mechanism uses the consistency of historical model gradient parameter updates from edge servers as the identification basis. It can effectively detect malicious updates from edge servers, improving the accuracy of the aggregated model. Experimental results show that the proposed method can resist poisoning attacks from 70% of malicious edge servers. It offers privacy protection, transparent model aggregation, and resistance to single-point failure. Furthermore, the method achieves high model accuracy and meets stringent security, accuracy, and traceability requirements in edge federated learning scenarios. Full article

Artificial light at night (ALAN) and noise pollution are two important stressors associated with urbanisation that can have a profound impact on animal behaviour and physiology, potentially disrupting biological rhythms. Although the influence of ALAN and noise pollution on daily activity patterns of songbirds has been clearly demonstrated, studies often focus on males, and the few that examined females have not included the potential influence of males on female activity patterns. Using free-living pairs of great tits (Parus major) as a model, we examined for the first time the effects of ALAN and noise pollution and their interaction on the onset of (vocal) activity in both members of a pair. We focused on the egg-laying phase, when both sexes are most vocally active. The onset of male dawn song, female emergence time from the nest box and the onset of female calling in the nest box were measured and used as a proxy for the chronotype. The repeatabilities for all chronotype proxies were high, with higher repeatabilities for males. Consistent with previous studies, ALAN advanced the onset of male dawn song, while it did not elicit a strong response in female emergence time. Additionally, our results suggest an indirect effect of ALAN on the onset of female vocal activity via acoustic interaction with the male. Noise pollution advanced the emergence time in females, while an interaction between ALAN and noise pollution was found for the onset of female calling. In agreement with previous studies, several covariables were shown to have an influence on the activity onset. Taking several proxies for chronotype into account, this study has provided robust evidence of effects of ALAN on male and female cavity-nesting songbirds during the egg-laying period. Full article

Background: Meaning in Life (MiL) represents a key variable in mental health models of personal recovery. There is a need for straightforward and concise instruments to assess this construct quantitatively in individuals diagnosed with severe mental illness (SMI). Objective: The aim of the present study was to test the psychometric properties of the Purpose in Life Test-Short Form (PIL-SF), a brief self-report measuring the presence of MiL, in a sample of individuals with SMI. Methods: The participants were 41 adults (21 women, 51.8% and 20 men, 48.2%) aged 18 to 65 years (M = 50.05; SD = 10.73) with a diagnosis of SMI (schizophrenia, 61%; bipolar disorder, 26.8%; borderline personality disorder, 7.3%; and major depression, 4.9%) and clinically stable. The PIL-SF, Satisfaction with Life Scale (SWLS), Oxford Happiness Questionnaire—6 Item (OHQ-6), Engagement in Meaningful Activities Survey (EMAS), and Seeking of Noetic Goals—8 Item (SONG-8) were used. Descriptive analysis, estimation of the internal consistency, and Confirmatory Factor Analysis of the PIL-SF were conducted. Furthermore, correlations between the PIL-SF, SWLS, OHQ-6, EMAS, and SONG-8 were calculated. Results: The PIL-SF showed acceptable internal consistency (ω = 0.81) and an excellent fit as a unidimensional scale (CFI = 1.000, TLI = 1.070, RMSEA = 0.000, SRMR = 0.021), confirming its factorial structure. Regarding construct validity, correlations between the PIL-SF and the SWLS (ρ = 0.54, p < 0.001), the OHQ-6 (ρ = 0.52, p < 0.001), and EMAS (ρ = 0.44, p < 0.005) were positive and significant, whereas the correlations between the PIL-SF and the SONG-8NfM (ρ = −0.35, p < 0.025) were negative and significant. Conclusions: The Spanish version of the PIL-SF appears to be a reliable and valid instrument to measure the presence of MiL in adults with SMI. Full article

This paper provides a fresh redemptive reading of Gen 3:16, viewed in light of a whole mosaic of canonical contexts and intertextual connections. These include, among others, the full equality without hierarchy of man and woman in Gen 1–2; the paradigmatic nature of egalitarian marriage with mutual submission between husband and wife in Gen 2:18–24; the rupture of husband–wife relationships in Gen 3:6–13; the covenant lawsuit of Gen 3:14–19; the meaning of mashal in Gen 1:16–18 and 4:7; the meaning of teshuqah and grammatical–syntactical parallels and contrasts in Gen 4:7 and Song 7:11 (Eng. v. 10); the redemptive aspects of the woman and her seed in Gen 3:15; and the intertextual connections with New Testament passages. Considering this mosaic of contexts and connections, it is suggested that Gen 3:16 must be viewed only in reference to marriage; it is never broadened to include man–woman gender relationships in general. In Gen 3:16, God provides a temporary, remedial measure to preserve harmony and unity in a ruptured marriage relationship, with an implicit call for husbands and wives to return as soon as possible from the mashal–teshuqah relationship to the paradigmatic egalitarian marriage set forth in Gen 2:24. This return to the divine creation ideal for marriage is empowered by the redemptive promises of Gen 3:15, confirmed in the reversal of the Gen 3:16 marital relationship articulated in the Song of Songs—the inspired commentary on Gen 1–3—particularly Song 7:11 [Eng. v. 10]), and reaffirmed in the consistent citations of Gen 2:24 (and not Gen 3:16) in the NT (Matt 19:5, 6; Eph 5:31).

Many musicologists and researchers of popular music have recently stressed the omnipresence of covers in today’s music industry. In the sociolinguistics of music, however, studio-recorded covers and their potential differences from ‘original’ compositions have certainly been acknowledged in passing, but very few sociolinguists concerned with the study of song seem to have systematically explored how language use may differ in such re-imagined musical outputs. This article reports on a study which examines the language use of 45 blues artists from three distinct time periods (viz., 1960s, 1980s, and 2010s) and three specific social groups (viz., African American; non-African American, US-based; and non-African American, non-US based) distributed over 270 studio-recorded original and cover performances. Through gradient boosting decision tree classification, it aims to analyze the artists’ use of eight phonological and lexico-grammatical features that are traditionally associated with African American English (viz., /aɪ/ monophthongization, post-consonantal word-final /t/ deletion, post-consonantal word-final /d/ deletion, alveolar nasal /n/ in <ing> ultimas, post-vocalic word-final /r/ deletion, copula deletion, third-person singular <s> deletion, and not-contraction). Our analysis finds song type (i.e., the distinction between covers and originals) to have no meaningful impact on artists’ use of the examined features of African American English. Instead, our analysis reveals how performers seem to rely on these features to a great extent and do so markedly consistently, regardless of factors such as time period, socio-cultural background, or song type. This paper hence builds on our previous work on the language use of blues performers by further teasing out the complex indexical and iconic relationships between features of African American English, authenticity, and the blues genre in its various manifestations of time, place, and performance types.

This paper presents a novel approach to automated music mixing, focusing on the optimization of loudness control in multi-track recordings. By taking into consideration the complexity and artistic nature of traditional mixing processes, we introduce a personalized multi-track leveling method using two types of approaches: a customized genetic algorithm and a neural network-based method. Our method tackles common challenges encountered by audio professionals during prolonged mixing sessions, where consistency can decrease as a result of fatigue. Our algorithm serves as a ‘virtual assistant’ to consistently uphold the initial mixing objectives, hence assuring consistent quality throughout the process. In addition, our system automates the repetitive elements of the mixing process, resulting in a substantial reduction in production time. This enables engineers to dedicate their attention to more innovative and intricate jobs. Our experimental framework involves 20 diverse songs and 10 sound engineers possessing a wide range of expertise, offering a useful perspective on the adaptability and effectiveness of our method in real-world scenarios. The results demonstrate the capacity of the algorithms to mimic decision-making, achieving an optimal balance in the mix that resonates with the emotional and technical aspects of music production.

Although music singing and sharing is a most common cultural activity, users are not allowed to instantly share their own songs due to fixed streaming and listening services on the music service platforms. In order to deal with instant singing and listening together with other users, this research was conducted to propose a mobile social karaoke system that supports group creation and music sharing via smartphones. The proposed karaoke system consists of a social music cloud that provides impromptu mobile singing and sharing services on the user’s devices. The social music cloud manages a group of users and supports data streaming and message sharing among the users’ devices. The users’ devices enable users to utilize karaoke services based on touch and voice-based natural interfaces in consideration of mobile specifications. After testing the system’s usability and stability, the results illustrated that the voice-based interface was effective in controlling and using the service according to the devices’ mobility and availability. In addition, when karaoke services are utilized in small groups, music transmission/reception is possible without being affected by the number of users. This study has three implications: first, it presented an important possibility for the creation of more active digital cultural spaces and changing mobile life by providing users with a recreation function; second, it provides convenient touch and voice UI for mobile users; and, third, it improves performance and management through its distributed processing.

Permian Ben Giang-Que Son and Triassic Van Canh granitic rocks are widely distributed across the southern Kontum Massif, the basement of which consists mainly of metasedimentary rocks. The Ben Giang-Que Son granitic rocks are classified as I- to S-type and ilmenite-series granitic rocks, while the Van Canh granitic rocks are classified as I-type and magnetite-series granitic rocks. Both granitic rock suites exhibit more or less adakitic properties, suggesting that the subduction of the high-temperature Song Ma Ocean crust, part of the Paleo-Tethys Ocean, beneath the Indochina Block produced adakitic magma. It is hypothesized that the differences between the two granitic rock suites were caused by differences in the quantities of incorporated continental crustal materials and carbon or graphite in clastic sedimentary rocks when their adakitic magma intruded into the continental crust. Based on their high initial Sr isotope ratios, the Ben Giang-Que Son granitic rocks evidently incorporated a higher quantity of continental crustal materials compared to the Van Canh granitic rocks, resulting in the former showing the signatures of ilmenite-series and I- to S-type granitic rocks. Consequently, the Ben Giang-Que Son granitic rocks have relatively high A/CNK ratios and high total Al contents in their biotite, whereas the Van Canh granitic rocks have low A/CNK ratios and low total Al contents in their biotite. The intrusion of the Ben Giang-Que Son granitic rocks caused high-temperature metamorphism, which decomposed some of the carbon or graphite in the surrounding continental crustal materials, such as clastic sedimentary rocks. Meanwhile, the Van Canh granitic rocks, which intruded later than the Ben Giang-Que Son granitic rocks, incorporated smaller quantities of carbon or graphite in continental crustal materials, resulting in them retaining the chemical characteristics of adakitic, magnetite-series, and I-type granitic rocks, different from the Ben Giang-Que Son granitic rocks.

In order to investigate the evolution of Chinese lacquering techniques, seven pieces of lacquer Lian from the Warring States Period to the Yuan Dynasty (475 BC–1368 AD) were analyzed by means of cross-section observation, Raman spectroscopy (RS), and thermally assisted hydrolysis and methylation pyrolysis coupled with gas chromatography/mass spectroscopy (Py-GC/MS). The results revealed that the lacquer Lian consisted of a three-layer structure, encompassing a pigment layer on the surface, an undercoat layer in the middle, and a ground layer. The red mineral pigment utilized was cinnabar, while a combination of Chinese lacquer and drying oil served as the primary organic material. Although lacquering techniques had undergone minimal changes from the Warring States Period to the Yuan Dynasty, the species of drying oil had changed, based on the fact that boiled tung oil was found in the ground layer of lacquerware from the Song Dynasty and the Yuan Dynasty. The present research provides direct evidence for the inheritance and development of Chinese lacquer technology. Full article

This paper studies the spatial forms and cultural sustainability of the Damazhan and Xiaomazhan historical area, the only area that reflects the development of the assembled-clan hall culture in Guangzhou. In the face of modernization and reconstruction, traditional culture plays an increasingly crucial role in modern cities, determining the expression of architectural uniqueness and continuous development that adapts to social needs. Therefore, preserving cultural characteristics is more relevant than ever. This study combines historical literature research with typo-morphological analysis to establish analytical strategies that link cultural sustainability with spatial evolution from the perspective of sustainable development. The analytical framework consists of three parts: First of all, through historical literature research, a thorough analysis is conducted on the cultural and social influencing factors from the Dynasties of Song, Yuan, Ming, Qing and the Republic of China to the reform and opening up period. Secondly, feature elements of the location are extracted, and a typo-morphological approach is used to analyze the sustained changes in spatial forms. Finally, the relationship between changes in block form and building types and the inheritance and development of traditional culture are demonstrated. The analytical results indicate that the continuity of cultural characteristics is embodied in the continuity of the block and architectural spatial characteristics, while cultural transformation and man-made social factors affect the changes in spatial forms. This paper combines the perspective of cultural sustainability analysis with the traditional typo-morphological approaches of urban spatial analysis, supplementing the existing typo-morphological methodology. In addition, guiding the development of urban morphology from the perspective of cultural sustainability is of prominent practical significance. Full article

Chris Cornell was a guitarist, singer, songwriter, and pioneer of grunge music. Cornell struggled with mental illness and addiction and incorporated these themes into his song lyrics. At age 52, Cornell died by suicide in his hotel bathroom following a live performance. This mixed-methods study examines Cornell’s song lyrics for references to negative words and themes related to depression and suicide. Two coders independently reviewed lyrical transcripts to identify the primary theme, secondary theme(s), and valence (positive or negative). Sentiment analysis, a natural language processing technique, was used to examine word frequency and valence. Songs (N = 215) were predominantly (79%) negative and contained more negative (N = 3244, 56.1%) than positive (N = 2537, 43.9%) words. Thematic analysis by stage of career shows a narrowing focus on depression, failed relationships, and morbid thoughts. Themes of depressed mood, death, and suicide were common and increased by stage of career. By applying qualitative and quantitative techniques to song lyrics, this study revealed that Cornell’s songs reflect a narrative of negativity consistent with someone experiencing depression and thoughts of death and suicide. Like personal notes and poems, song lyrics may reflect symptoms of depression and suicidal thoughts warranting clinical attention. Full article
