We obtain different categories of singularities of fuzzy retracts, fuzzy deformation retracts, and fuzzy foldings on fuzzy fundamental groups of the fuzzy Friedmann–Lemaître–Robertson–Walker Space ${\tilde{W}}^4$. The fuzzy fundamental groups of fuzzy submanifolds in ${\tilde{W}}^4$ are characterized combinatorially using these fuzzy geometrical transformations. Also, the fuzzy fundamental groups of the fuzzy geodesics and the limit fuzzy foldings of ${\tilde{W}}^4$ are described. New types of fuzzy singularity of some fuzzy geometrical transformations of ${\tilde{W}}^4$ are obtained. Finally, the regularity of some other fuzzy retract singularities are discussed.

The present study investigates how US Southerners perceive second language (L2) speech by recruiting 170 undergraduate students who spoke Southern American English to listen to recordings of four speakers (US, Bangladeshi, Chinese, and Saudi Arabian) and evaluate their attributes. The listeners were grouped based on their ethnic affiliation: African American, Anglo-American, and Asian/Hispanic/multi-racial. A random half were primed, being asked questions about whether/how other people had negatively commented on their accents. Results showed no effect of priming on speech ratings. Moreover, whilst African American and Anglo-American listeners rated L2 speakers lower than the L1 speaker in almost all aspects, Asian/Hispanic/multi-racial listeners did not. Full article

Although prosodic differences in autistic individuals have been widely documented, little is known about their ability to perceive and interpret specific prosodic features, such as contrastive pitch accent—a prosodic signal that places emphasis and helps listeners distinguish between competing referents in discourse. This study addresses that gap by investigating the extent to which autistic children can (1) perceive contrastive pitch accent (i.e., discriminate contrastive pitch accent differences in speech); (2) interpret contrastive pitch accent (i.e., use prosodic cues to guide real-time language comprehension); and (3) the extent to which their ability to interpret contrastive pitch accent is associated with broader language and social communication skills, including receptive prosody, pragmatic language, social communication, and autism severity. Twenty-four autistic children and 24 neurotypical children aged 8 to 14 completed an AX same–different task and a visual-world paradigm task to assess their ability to perceive and interpret contrastive pitch accent. Autistic children demonstrated the ability to perceive and interpret contrastive pitch accent, as evidenced by comparable discrimination ability to neurotypical peers on the AX task and real-time revision of visual attention based on prosodic cues in the visual-world paradigm. However, autistic children showed significantly slower reaction time during the AX task, and a subgroup of autistic children with language impairment showed significantly slower processing of contrastive pitch accent during the visual-world paradigm task. Additionally, speed of contrastive pitch accent processing was significantly associated with pragmatic language skills and autism symptom severity in autistic children. Overall, these findings suggest that while autistic children as a group are able to discriminate prosodic forms and interpret the pragmatic function of contrastive pitch accent during spoken language comprehension, differences in prosody processing in autistic children may be reflected not in accuracy, but in speed of processing measures and in specific subgroups defined by language ability.

Acquiring prosodic focus marking in a second language (L2) is difficult for learners whose native language utilizes strategies that differ from those of the target language. German typically uses pitch accents (L+H*/H*) to mark focus, while (Modern Standard) Arabic preferably employs a syntactic strategy (word order) or lexical means. In Syrian Arabic, a variety which is predominantly oral, pitch accents are used to mark focus, but the distribution and types are different from German. The present study investigates how Syrian Arabic learners of German prosodically mark focus in L2 German. A question–answer paradigm was used to elicit German subject-verb-object (SVO)-sentences with broad, narrow, or contrastive focus. Productions of advanced (C1, N = 17) and intermediate (B1/B2, N = 8) Syrian Arabic learners were compared to those of German controls (N = 12). Like the controls, both learner groups successfully placed pitch accents on focused constituents. However, learners, especially those with lower proficiency, used more pitch accents in non-focal regions than the controls, revealing challenges in de-accentuation. These may result from the larger number of phrase boundaries in learners’ productions, which in turn might be explained by transfer from the L1 or aspects of general fluency. Learners also differed from the controls with respect to accent type. They predominantly used H* for narrow or contrastive focus (instead of L+H*); proficiency effects played only a minor role here. Our study hence reveals an intricate interplay between cross-linguistic influence and proficiency in the L2 acquisition of prosodic focus marking, targeting a language pair so far underrepresented in the literature (German vs. Syrian Arabic).

This paper introduces an innovative mobile-assisted language-learning (MALL) system that harnesses deep learning technology to analyze pronunciation patterns and deliver real-time, personalized feedback. Drawing inspiration from how the human brain processes speech through neural pathways, our system analyzes multiple speech features using spectrograms, mel-frequency cepstral coefficients (MFCCs), and formant frequencies in a manner that mirrors the auditory cortex’s interpretation of sound. The core of our approach utilizes a convolutional neural network (CNN) to classify pronunciation patterns from user-recorded speech. To enhance the assessment accuracy and provide nuanced feedback, we integrated a fuzzy inference system (FIS) that helps learners identify and correct specific pronunciation errors. The experimental results demonstrate that our multi-feature model achieved 82.41% to 90.52% accuracies in accent classification across diverse linguistic contexts. The user testing revealed statistically significant improvements in pronunciation skills, where learners showed a 5–20% enhancement in accuracy after using the system. The proposed MALL system offers a portable, accessible solution for language learners while establishing a foundation for future research in multilingual functionality and mobile platform optimization. By combining advanced speech analysis with intuitive feedback mechanisms, this system addresses a critical challenge in language acquisition and promotes more effective self-directed learning.

This article investigates the phenomenon of missionary landscape photography with an eye to contributing to the field of environmental history. It uses photos made by Dutch missionaries in newly independent Nigeria between about 1960 and 1968. The missionaries were focused on economic development, agricultural innovation, medical aid, and strengthening local churches. Most photos reflect these preoccupations. Even so, many of the photos also portray trees, animals, agricultural fields, and especially landscapes. We argue that missionaries, through their landscape photography, were instrumental in developing a Western gaze of tropical nature, even if their photography cannot be defined as environmental. By comparing the photos to journals of the missionaries, we can distinguish distinct visual and textual narratives that are obviously connected but also have different accents. Whereas both portray tropical wilderness as exotic or as a challenge for missionary efforts, the photos are less optimistic about opportunities for mission by emphasizing desolate, uncultivated landscape. Overall, we argue that missionary photography offers a rich resource for the study of environmental history. Full article

This paper presents the design and evaluation of e-SoundWay, a cross-platform serious game developed to improve English phonetic competence through a multimodal and narrative-driven approach. While the platform is specifically tailored to meet the needs of Spanish-speaking learners, it is adaptable for a wider range of English as a Foreign Language (EFL) users. e-SoundWay offers over 600 interactive multimedia minigames that target three core competencies: perception, production, and transcription. Learners progress along a gamified version of the Camino de Santiago, interacting with characters representing diverse English accents. A mixed-methods evaluation combining pre- and post-tests with a user experience questionnaire revealed statistically significant improvements across all domains, particularly in perception. Reduced post-test variability indicated more equitable learning outcomes. User satisfaction was high, with 64% of participants reporting satisfaction with their phonetic progress and 91% stating they would recommend the platform. These findings highlight the educational effectiveness, accessibility, and motivational value of e-SoundWay, reinforcing the role of serious games and multimodal technologies in delivering inclusive and engaging pronunciation instruction.

Midlatitude westerly and East Asian summer monsoon (EASM) are crucial circulation systems in the upper and lower troposphere of East Asia that significantly influence mid-summer precipitation pattern. However, their synergistic effect on mid-summer precipitation in North China (NC) remains unclear. In this study, the concurrent variations of mid-summer westerly and EASM are categorized into two configurations: strong westerly–strong EASM (SS) and weak westerly–weak EASM (WW). At the synoptic timescale, the SS configuration significantly enhances precipitation in NC, whereas the WW configuration suppresses mid-summer rainfall. The underlying mechanism is that the SS pattern stimulates an anomalous quasi-barotropic cyclone–anticyclone pair over the Mongolian Plateau–Yellow Sea region. Two anomalous water vapor channels (westerly-driven and EASM-driven water vapor transport) are established in the southern and western peripheries of this cyclone–anticyclone pair, ensuring abundant moisture supply over NC. Meanwhile, frequently occurring westerly jet cores in northern NC form a jet entrance region, favoring strong upper-level divergent pumping and deep accents in its southern flank. This synergy between strong westerlies and EASM enhances both the moisture transports and ascending movements, thereby increasing precipitation over NC. Conversely, the atmospheric circulation associated with the WW pattern exhibits opposite characteristics, resulting in decreased NC rainfall. Our findings elucidate the synoptic-scale influences of westerly–monsoon synergy on mid-summer rainfall, through regulating moisture transports and westerly jet-induced dynamic uplift, potentially improving predictive capabilities for mid-summer precipitation forecasting.

In the twentieth century and into the present one, scholars working in the field of Christian pastoral care have concentrated their efforts in both well-established and emerging areas. Traditionally, thinking about pastoral care has been oriented to the person suffering from an existential, developmental, spiritual, or moral crisis (or a combination of these). With the emergence of the psychotherapeutic psychology of Freud, Jung, Erikson, Kohut, Berne, Perls, and others, a new focus on pastoral psychotherapy emerged. Taking things in a very different direction, a host of pastoral theologians issued a call to not only care for the individual, but also for the socio-political world that is oppressive and exclusionary for many. Still others promoted pastoral care and counseling as a ministry of the Christian Church. Finally, those animated by the ancient tradition of cura animarum accented pastoral care as spiritual formation. It is to these latter two themes that this article is addressed. What is proposed is a practical prompt card approach to spiritual formation in the congregation that is holistic and runs in the first instance over six to eight weeks. The four areas covered are spiritual practices, spiritual character (fruits of the Spirit), moral character, and positive psychology. Full article

There is a growing body of evidence regarding the barriers to participation in sport for people with sight loss and for people from ethnically diverse communities. However, far less is known about the experience of people with sight loss who are also from ethnically diverse communities. Semi-structured interviews with people with lived experience and focus groups with civil society organisations that work with people with sight loss in the UK were undertaken. The aim was to explore how issues concerning ethnicity, culture, and heritage overlap with sight loss to affect sport participation. This research found that the intersecting occurrences of sight loss and ethnicity/cultural factors, as well as other socio-demographic factors like gender, compound and exacerbate the barriers to sport participation for people with sight loss from ethnically diverse communities. Further research is needed in different settings to unpack the heterogeneity related to sight loss, ethnicity, and sport. Full article

Speech Emotion Recognition (SER) technology helps computers understand human emotions in speech, which fills a critical niche in advancing human–computer interaction and mental health diagnostics. The primary objective of this study is to enhance SER accuracy and generalization through innovative deep learning models. Despite its importance in various fields like human–computer interaction and mental health diagnosis, accurately identifying emotions from speech can be challenging due to differences in speakers, accents, and background noise. The work proposes two innovative deep learning models to improve SER accuracy: a CNN-LSTM model and an Attention-Enhanced CNN-LSTM model. These models were tested on the Ryerson Audio-Visual Database of Emotional Speech and Song (RAVDESS), collected between 2015 and 2018, which comprises 1440 audio files of male and female actors expressing eight emotions. Both models achieved impressive accuracy rates of over 96% in classifying emotions into eight categories. By comparing the CNN-LSTM and Attention-Enhanced CNN-LSTM models, this study offers comparative insights into modeling techniques, contributes to the development of more effective emotion recognition systems, and offers practical implications for real-time applications in healthcare and customer service.

Ionic liquids (ILs) have been explored as a way of improving the performance of ZnO-based optoelectronic devices; however, there are few fundamental studies of the IL/ZnO interface. Here, the adsorption of the IL 1-octyl-3-methylimidazolium tetrafluoroborate [C₈C₁Im][BF₄] on ZnO (0001) and ZnO ($10\overline{1}0$) has been studied using synchrotron-based soft X-ray photoelectron spectroscopy. The results indicate that [C₈C₁Im][BF₄] is deposited intact on the ZnO (0001) surface; however, there is some dissociation of [BF₄]⁻ anions, resulting in boron atoms attaching to the oxygen atoms in the ZnO surface and forming B₂O₃. In contrast, the deposition of [C₈C₁Im][BF₄] on the ZnO ($10\overline{1}0$) surface at −150 °C results in the appearance of more chemical environments in the spectra. We propose that the high temperature of the IL evaporator causes some conversion of [C₈C₁Im][BF₄] to a carbene–borane adduct, resulting in the deposition of both the IL and adduct onto the ZnO surface. The adsorption and desorption of the analogous IL 1-butyl-3-methylimidazolium tetrafluoroborate [C₄C₁Im][BF₄] was investigated on ZnO (0001) using synchrotron-based soft X-ray photoelectron spectroscopy. The results indicate that [C₄C₁Im][BF₄] is deposited largely intact at −150 °C and forms islands when heated to room temperature. When heated to over 80 °C, it begins to react with the ZnO surface and decomposes. This is a much lower temperature than the long-term thermal stability of the pure IL, quoted in the literature as ~400 °C, and of IL on powdered ZnO, quoted in the literature as ~300 °C. This indicates that the ZnO surface may catalyse the thermal decomposition of [C₄C₁Im][BF₄] at lower temperatures. This is likely to have a negative impact on the potential use of ILs in ZnO-based photovoltaic applications, where operating temperatures can routinely reach 80 °C. Full article

The criminological approach to relapse is based, on the one hand, on the theories that explain the risk of relapse, including the risk level assessment tools, and on the other hand, on the rehabilitation theories—the Risk-Need-Responsivity (RNR) Model and The Good Live Model (GLM), which explain the mechanisms of reducing the risk of relapse in the assisted desistance paradigm. The objectives of this study focus on identifying the predictors of relapse in correlation with relapse inhibitors that combine a number of personal, psycho-emotional factors with psychopathological, socio-economic, and cultural accents. The method used is that of the case study from the perspective of clinical criminology, referring to forensic psychiatry through specific techniques and working procedures of some institutions in the correctional system—territorial structures of probation (TSP) in cooperation with the penitentiary system. The results of the study focus on the impact of standardized programs on the reduction in the risk of relapse after prison (RRR) and on personal and socio-familial factors involved in post-executional surveillance and post-criminal assistance. In conclusion, the current study highlights the need to corroborate the clinical or subjective assessment of relapse risk with the actual or objective assessment, which also includes the risk of violence in the framework of community monitoring from the perspective of community or social psychiatry.

In today’s globalized world, foreign language (FL) communication is characterized by the presence of regional variations that can impact L2 learners’ speech perception in their target language. While it is essential for FL programs to prepare their students for real-world language variation, research on learner perception of spoken regional varieties remains scarce, especially for less commonly taught languages, such as Italian. To address this, this study used a quantitative approach to explore to what extent listeners’ background factors (i.e., accent familiarity, contact with Italian speakers, heritage learner status, L1) and speaker accent impact FL learners’ perceptions of (1) intelligibility, (2) comprehensibility, and (3) acceptability of regionally accented Italian speech. A total of forty-seven FL learners of Italian listened to the speech of six Italian native speakers with different regional accents (two each from Northern, Central, and Southern Italy), rated them for comprehensibility and acceptability, and transcribed utterances for intelligibility. Mixed-effects models revealed statistically significant effects of speaker accent and listener L1 background on all three perceptual constructs. Additionally, greater contact corresponded with higher comprehensibility, while heritage learners rated speech as less acceptable for educational contexts. Listeners’ overall positive perception of regionally accented speech encourages the introduction of authentic spoken varieties in the FL classroom. Full article

This study examines the acoustic properties of vowels in foreigner-directed speech (FDS) in interactions between female Omani-Arabic-speaking employers and their foreign domestic helpers (FDHs). Particularly, it investigates whether Arabic corner vowels /i:/, /a:/, and /u:/ undergo acoustic adaptations in FDS. The study also explores the influence of foreign interlocutors’ psycholinguistic characteristics, such as degree of foreign accent, religion, and length of residence (LoR), on the extent of these adaptations. Data were collected from 22 Omani-Arabic-speaking women interacting with their 22 FDHs and with a native speaker (NS) confederate using a spot-the-difference task. Acoustic measures including vowel space area, formant frequency measures (F1 and F2), fundamental frequency (f0), intensity, and duration were compared across speech directed at FDHs and the NS. The results revealed that FDS exhibited greater vowel space expansion, higher F1, and increased pitch (f0) and intensity compared to speech directed at the NS confederate. However, FDS did not significantly affect F2 values. Unexpectedly, vowel duration in FDS was shorter than in speech directed at the NS. Furthermore, the psycholinguistic factors of foreign interlocutors had no significant effect on vowel space expansion in FDS. These findings provide evidence that FDS is characterized by heightened prosodic and acoustic features, potentially contributing to clearer speech. Additionally, the study highlights that NSs employ FDS when interacting with foreigners perceived to have a foreign accent. Full article
