A room of one’s own? The consequences of living density on individual well-being and social anomie

Abstract The global housing affordability crisis and COVID shutdowns have put living space inequality back on the political agenda. Drawing on Durkheim’s theory of anomie and density, this paper argues that on how many square meters a society lives matters for how stable or anomic it develops. Using data from the Swiss Household Panel, we examine the selection, short-term, and dynamic effects associated with transitions to overcrowded and under-occupied dwellings. We conceptualize these transitions as disruptive events that require a reconfiguration of personal and social equilibria in individuals’ lives. While overcrowded housing leads to a heightening of emotional states and more tense internal household dynamics, people respond by adjusting their leisure activities and restructuring their support networks from strong to weak ties. Conversely, moving to an under-occupied dwelling is associated with melancholic emotional stabilization, but improves household balance and leads to consolidation of the core network of relatives at the expense of outer social circles. We conclude that the classical characterization of anomie as a mismatch between personal means and societal ends should be understood as a multifaceted phenomenon in which meso-level social networks can be a crucial means to cope with disruptions that arise at other levels.

Language Dominance in the Input and Use Patterns of Cameroon’s Special Bilingual Students

This paper examines dominance in the language input and use patterns of students of Cameroon’s Special Bilingual Education Programme (SBEP). The participants were 373 bilingual students from 10 schools set in French-speaking Cameroon, who submitted self-ratings via an adapted version of the Bilingual Language Profile questionnaire by Birdsong, Gertken and Amengual (2012). The data were analysed using the subtraction method to determine dominance. The results showed a consistent pattern of OL1-dominance for all the three domains considered under language input (viz. listening, reading, and watch time), but a more contrasted pattern for language use, as the respondents were found to be French-dominant (or slightly OL1-dominant to balanced) in the outer circle of relationships (circle of friends and school environment) and OL1-dominant in the inner circle (self-talk and family circle). The findings of this study suggest that individual language use is more significantly impacted by societal dominance than language input is, most likely because the latter is less constrained by relationships and offers a greater possibility of choice. They equally suggest that there is a directionality in the influence of societal dominance, with a decreasing effect from the public to the private sphere. Lastly, the study underscores the powerful negative impact the lack of official recognition can have on the maintenance of local ethnic languages in a multilingual context.

"Folding Fan Flap": A Novel and Dependable Surgical Technique for Crow's Feet Correction by Z-Plasty of Orbicularis Oculi Muscle.

The challenge of crow's feet surgical correction is to minimize the complication caused by orbicularis oculi muscle (OOM) resection while ensuring the operative effect. This study aims to propose a novel technique to solve this problem and evaluate its efficacy. From January 2022 to April 2024, all patients who received "Folding fan flap" in our institution were included. The outer third of the OOM below the lateral canthus was dissected and received Z-plasty to exchange width for length and reconstruct the muscle dynamics in a non-circular direction. Preoperative and postoperative smiling crow's feet were assessed by two independent physicians using the Lemperle wrinkle scale. At least six months after surgery, patient satisfaction with wrinkle correction, naturalness of facial expression, and local flattening was subjectively evaluated on a five-point scale. Complications including hematomas, incomplete eyelid closure, facial stiffness, and forehead numbness were recorded. A total of 32 patients (63 sides) were included with a mean follow-up of 13.9 ± 5.2 months. Postoperative assessments showed a significant reduction in Lemperle's score from 4.8 ± 0.4 to 1.5 ± 0.5 (P=0.000). Regarding the satisfaction of surgical outcomes and the naturalness of facial expressions, thirty patients (93.8%) were very satisfied. There were no severe complications such as hematomas and incomplete eyelid closure. Preliminary clinical studies demonstrated the efficacy of this technique in ensuring outcomes while preserving normal dynamic expressions. By Z-plasty of the outer circle of OOM, the muscle dynamic was successfully modified rather than eradicated. This journal requires that authors assign a level of evidence to each article.

English varieties in Thai higher education: Views of international university students across Kachru’s circles

This qualitative study aimed to investigate the perceptions and adaptation strategies of international university students from Kachru’s Inner, Outer, and Expanding Circles regarding English varieties in Thai higher education. For data collection, the study used semi-structured interviews with six students chosen through purposive sampling: one from the Inner Circle, two from the Outer Circle, and three from the Expanding Circle. Qualitative content analysis was used to analyze the data. The research aimed to provide a comprehensive understanding of how these students experience and engage with English varieties within their English programs. The context of globalization and internationalization highlights the growing prevalence of English programs in Thai universities, making it essential to explore how diverse linguistic backgrounds impact students’ learning experiences. The findings reveal that students encounter distinct challenges based on the English varieties, affecting the participants’ academic adaptation and overall engagement. The study underscores the importance of acknowledging and incorporating multiple English varieties into educational practices to support international students better. This research contributes to the broader discourse on Global Englishes (GE) by analyzing qualitative data from interviews, emphasizing the need for inclusive and adaptable pedagogical approaches.

Navigating linguistic ideologies and market dynamics within China’s English language teaching landscape

Abstract This study explores the intricate interplay of linguistic ideologies, market dynamics, and linguistic habitus within the context of English language education in China. Analysis of Chinese English language teachers’ (CELTs) discourse on linguistic insecurity reveals a strong association between accentedness and incompetence, as well as between nativeness and teacher expertise. Despite dissatisfaction with nativeness-oriented criteria prevalent in the field, most CELTs reported experiencing anxiety due to the social stigma surrounding Mandarin-accented English. While certain Inner Circle English varieties are viewed as the most valuable capital, local and other non-Inner Circle varieties are considered the least valuable. Notably, Mandarin-accented English gains higher symbolic value than other perceived nonstandard English varieties beyond the teaching domain. This pricing mechanism within China’s English language teaching (ELT) landscape deviates from the price formation model of world Englishes proposed in previous work, which assigns a greater value to Outer Circle varieties than Expanding Circle varieties. By contextualizing CELTs’ experiences within broader language policies, this study illustrates how national interests, beyond the influence of Inner Circle publishers, intensify native-speakerism in China’s ELT market, thus emphasizing the intricate nature of explaining nuanced pricing patterns in the autonomous market within Expanding Circle contexts.

Exploring the medicinal potential of Dendrobium: Uncovering the spatial distribution of flavonoids and alkaloids in 15 species of Dendrobium using MALDI-MSI

Dendrobium, the second largest genus in the Orchidaceae family, has been regarded as a valuable medicinal plant throughout Chinese history. Secondary metabolites present in the stem of Dendrobium, including alkaloids and flavonoids, confer significant pharmacological effects such as anti-inflammatory, antibacterial, immunomodulatory, antitumor, and antioxidant properties. To our knowledge, this study is the first to apply matrix-assisted laser desorption/ionization mass spectrometry imaging (MALDI-MSI) technology to comprehensively identify the spatial distribution of secondary metabolites, particularly flavonoids and alkaloids, in the mature stems of 15 common Dendrobium species. By analyzing the matching scores and relative concentrations of compounds, 20 flavonoids and 19 alkaloids with high identification credibility were identified, along with 4 sesquiterpenoid compounds. Their spatial distributions and compositions were analyzed, and the results revealed that despite the similar structural basis of the stems in the 15 Dendrobium species, significant differences existed in the distribution of secondary metabolites among different species. Flavonoids and alkaloids with different medicinal effects exhibited certain specific distribution patterns; for instance, flavonoids with antioxidant effects were mostly concentrated in the outer circle of thin-walled cells of Dendrobium stems, whereas those with antitumor effects were found in higher concentrations in the central areas of some Dendrobium species than in the periphery. Alkaloids with antitumor properties typically exhibited a higher concentration in peripheral thin-walled cells than in central regions. Furthermore, statistical analysis was conducted on the content of secondary metabolites with different effects among the 15 Dendrobium species to identify species with greater medicinal potential in terms of antioxidant and antitumor effects. The findings of this study not only enhance our understanding of the distribution patterns of flavonoids and alkaloids within Dendrobium stems but also offer valuable insights for the medicinal development and quality assessment of Dendrobium.

Eye-tracking analysis of attentional disengagement in phobic and non-phobic individuals.

This study investigated threat-related attention biases using a new visual search paradigm with eye tracking, which allows for measuring attentional disengagement in isolation. This is crucial as previous studies have been unable to distinguish between engagement, disengagement, and behavioral freezing. Thirty-three participants (Mage = 28.75 years, SD = 8.98; 21 women) with self-reported specific phobia (spiders, snakes, and pointed objects) and their matched controls (Mage = 28.38 years, SD = 8.66; 21 women) took part in the experiment. The participants were instructed to initially focus on a picture in the center of the screen, then search for a target picture in an outer circle consisting of six images, and respond via a button press whether the object in the target picture was oriented to the left or right. We found that phobic individuals show delayed disengagement and slower decision times compared with non-phobic individuals, regardless of whether the stimulus was threat-related or neutral. These results indicate that phobic individuals tend to exhibit poorer attentional control mechanisms and problems inhibiting irrelevant information. We also confirmed a threat-unrelated shared feature effect with complex stimuli (delayed disengagement when an attended stimulus and an unattended target share common stimulus features). This process might play a role in various experimental setups investigating attentional disengagement that has not yet been considered. These findings are important, as good attentional control may serve as a protective mechanism against anxiety disorders.

Relationship between the inner setting of CFIR and the delivery of the Healthy School Recognized Campus initiative: a mixed-methods analysis

IntroductionHealthy School Recognized Campus (HSRC) is a Texas A&M AgriLife Extension initiative that promotes the delivery of multiple evidence-based physical activity and nutrition programs in schools. Simultaneous delivery of programs as part of HSRC can result in critical implementation challenges. The study examines how the inner setting constructs from the Consolidated Framework for Implementation Research (CFIR) impact HSRC program delivery.MethodsWe surveyed (n = 26) and interviewed (n = 20) HSRC implementers (n = 28) to identify CFIR inner setting constructs related to program acceptability, appropriateness, and feasibility. Using a concurrent mixed-methods design, we coded interviews using the CFIR codebook, administered an inner setting survey, tested for relationships between constructs and implementation outcomes via chi-square tests, and compared quantitative and qualitative results.ResultsStakeholders at schools that implemented one program vs. more than one program reported no differences in acceptability, appropriateness, or feasibility outcomes (p > .05); however, there was a substantial difference in reported program minutes (1118.4 ± 951.5 vs. 2674.5 ± 1940.8; p = .036). Available resources and leadership engagement were related to HSRC acceptability (r = .41; p = .038 and r = .48; p = .012, respectively) and appropriateness (r = .39; p = .046 and r = 0.63; p = .001, respectively). Qualitative analyses revealed that tangible resources (e.g., curriculum, a garden) enabled implementation, whereas intangible resources (e.g., lack of time) hindered implementation. Participants also stressed the value of buy-in from many different stakeholders. Quantitative results revealed that implementation climate was related to HSRC acceptability (r = .46; p = .018), appropriateness (r = .50; p = .009), and feasibility (r = .55; p = .004). Learning climate was related to HSRC appropriateness (r = .50; p = .009). However, qualitative assessment of implementation climate subconstructs showed mixed perspectives about their relationship with implementation, possibly due to differences in the compatibility/priority of different programs following COVID-19. Networks/communication analysis showed that schools have inner and outer circles of communication that can either benefit or hinder implementation.ConclusionFew differences were found by the number of programs delivered. Implementation climate (i.e., compatibility, priority) and readiness for implementation (i.e., resources and leadership engagement) were important to HSRC implementation. Strategies that focus on reducing time-related burdens and engaging stakeholders may support HSRC’s delivery. Other constructs (e.g., communication, access to knowledge) may be important to the implementation of HSRC but need further exploration.

Inner Circle Ideology Domination in a National Commercial EFL Textbook: A Case of Indonesian Islamic-affiliated Schools

This study employs an analysis of visual images in English textbooks used in Islamic-affiliated schools through the lens of Kachru’s three-circle model of English, which categorizes English-speaking countries into Inner, Outer, and Expanding circles. This study aims to explore how these images reflect and reinforce linguistic and cultural ideologies associated with each circle. A qualitative content analysis was implemented, focusing on the visual images within English textbooks, which were categorized based on the representation of cultural elements. Data analysis was implemented using a coding scheme and Critical Discourse Analysis framework, examining the power relations and ideological influences represented by the visual content of the textbook. Results show that inner circle culture was dominantly represented (67.9%) in the textbook of its visual use. Western-looking people, outfits, movies, and food represent the images used in the textbook. The finding suggests that textbooks used in English teaching at Islamic affiliated schools, or madrasas, must be carefully designed and selected to adjust students’ needs and school context, as teaching a foreign language can carry others’ ideologies and power.

Detecting angloversal tendencies in the outer circle: a pilot study on a Maltese English speaker

Abstract World Englishes constitute an ever-developing study field where keeping track of the real-time changes which occur in language usage is a challenging task. This chapter aims at broadening the application field of the research on angloversals, described in literature as particular features divergent from Standard English and shared by English varieties across the world regardless of their geographical proximity or cultural affiliation. The present qualitative study hypothesises the presence of angloversals in Maltese English and considers a blended methodological approach to verify the research hypothesis. The study was performed on selected oral excerpts taken from a random interview to a speaker of the Maltese English continuum. Both the interviewee and the interviewer are native Maltese speakers and communicated in English all throughout the interview with no instances of code mixing between the two languages. Syntactical structures containing the overuse of the progressive aspect, article omission and resumptive pronouns, as well as unmarked phonology traits have been included in the angloversal categories by previous research on the matter. Said features are particularly found in contexts where language contact has had an impact on both the substrate and superstrate languages. This is the case for the Maltese context, where explanations for the plausible presence of the above features are to be sought in the realms of transfer from Maltese to English, language universals and pragmatic principles.

The ‘Coloured’ connection of Namibian English

AbstractAmong the first English speakers in Namibia, South African Coloureds came to form an essential part of an ethnically fluid intermediate social class in colonial Namibia. This study seeks to pinpoint to what extent Coloured English varieties have been contributing to Namibian English and how much prestige is attached to them. To this end, this study simultaneously uses linguistic and perceptual data. One dataset consists of English phonetic data elicited from a representative urban sample of young Namibians. That dataset is analysed to establish what phonetic features mark out Coloured Namibian English varieties and to what extent they are found in other ethnolinguistic varieties and across social classes. The study then reports on a verbal guise experiment whose aim is to establish how young Namibians rate Coloured Namibian English varieties. Finally, the study analyses folk comments on Namibian English accents elicited from young Namibian focus groups. The study finds that, in terms of vowel realization patterns, Coloured Namibian English varieties sit in between White and Black Namibian English varieties, forming part of a continuum of which one extremity displays a White South African English imprint. The less ‘Afrikaans‐accented’ Coloured English varieties—associated with women—are developing middle‐class indexicalities. The fact that these varieties are targeted by young Black women and are perceived as ‘General Namibian English’, the study concludes, confirms that Namibian English is norm‐developing, as befits any Outer Circle variety. It is loosely tied to (South African) Inner Circle norms and has entered Phase 4 (‘endonormative stabilization’) of E. Schneider's Dynamic Model. The normative influence of Namibian Coloured English, the study argues, shows that the Dynamic Model needs fundamental adjustment to properly account for the role of non‐Europeans in Outer Circle dynamics.

A kinematic analysis of the giant molecular complex W3: Possible evidence for cloud–cloud collisions that triggered OB star clusters in W3 Main and W3(OH)

Abstract W3 is one of the most outstanding regions of high-mass star formation in the outer solar circle, and includes two active star-forming clouds: W3 Main and W3(OH). Based on a new analysis of the ${^{12}\text{CO}(J = 2-1)}$ data obtained at $38^{\prime \prime }$ resolution, we have found three clouds that have molecular masses from 2000 to $8000\, {M_\odot }$ at velocities $-50\:\rm{km\: s^{-1}}$, $-43\:\rm{km\:s^{-1}}$, and $-39\:\rm{km\:s^{-1}}$. The $-43\:\rm{km\:s^{-1}}$ cloud is the most massive one, overlapping with the $-39\:\rm{km\:s^{-1}}$ cloud and the $-50\:\rm{km\:s^{-1}}$ cloud toward W3 Main and W3(OH), respectively. In W3 Main and W3(OH), we have found typical signatures of a cloud–cloud collision, i.e., the complementary distribution with/without a displacement between the two clouds and/or a V-shape in the position–velocity diagram. We frame a hypothesis that a cloud–cloud collision triggered the high-mass star formation in each region. The collision in W3 Main involves the $-39\:\rm{km\:s^{-1}}$ cloud and the $-43\:\rm{km\:s^{-1}}$ cloud. The collision likely produced a cavity in the $-43\:\rm{km\:s^{-1}}$ cloud that has a size similar to the $-39\:\rm{km\:s^{-1}}$ cloud and triggered the formation of young high-mass stars in IC 1795 $2\:$Myr ago. We suggest that the $-39\:\rm{km\:s^{-1}}$ cloud is still triggering the high-mass objects younger than $1\:$Myr currently embedded in W3 Main. On the other hand, another collision between the $-50\:\rm{km\:s^{-1}}$ cloud and the $-43\:\rm{km\:s^{-1}}$ cloud likely formed the heavily embedded objects in W3(OH) within $\sim\! 0.5\:$Myr ago. The present results favour an idea that cloud–cloud collisions are common phenomena not only in the inner solar circle but also in the outer solar circle, where the number of reported cloud–cloud collisions is yet limited (Fukui et al. 2021, PASJ, 73, S1).

World Englishes and sociolinguistic variation

AbstractThis article discusses the connections between world Englishes and sociolinguistic variation. It begins with an overview of the field of sociolinguistic variation, and also highlighting contemporary approaches to world Englishes, with specific reference to the sociolinguistic realities (in the Kachruvian sense) of Outer Circle contexts. The article then proceeds to examine language variation studies with a focus on vernacular language practices and the growing use of corpus approaches. It then presents the contributions to this special issue on world Englishes and sociolinguistic variation, before considering possible future directions for research.

A calibration method of line-structured light system for measuring outer circle dimension during machining

The line-structured light system is widely utilized for various 3D profile measurements due to its convenience and high efficiency. However, the existing calibration methods primarily focus on establishing the relationship between object points and image points, which imposes stringent requirements on the calibration target. To address this issue, a practical calibration method based on interpolation function is proposed in order to measure a specific 3D profile - namely, the diameter of a rotating workpiece during machining. Firstly, the light stripe projected onto an ordinary machined workpiece by a light plane is captured using a Charge-Coupled Device (CCD) camera and subsequently fitted to a quadratic elliptic curve after undergoing image processing. Subsequently, the cubic spline interpolation function is selected to directly establish a mapping relationship between geometric characteristics of the elliptic curve and the diameter measurement. Several experiments are conducted to evaluate the proposed methods. The experimental results demonstrate that compared with two comparison methods, our approach reduces the calibration error of linear structured light systems by 69 % and 51 %, respectively; furthermore, it enables restoration of smooth and detailed 3D models through parallel movement of the system. Moreover, our entire calibration process proves practicable in simplifying experimental procedures while remaining suitable for industrial inspection applications.

Comment Markers in Spoken English in Korea

The present study examines the use of four categories of comment markers among Korean speakers of English, a category of grammatical items whose use is prompted by pragmatic factors, using the data from the elicited conversation in English. Previous research on comment markers has suggested that comment markers are more frequent in the Inner Circle varieties than in the Outer Circle varieties and that there are systematic differences in the distribution of comment markers between Kachru’s Inner and Outer Circles. Since English is learned and used as an important foreign language in Korea, Korean society which belongs to the Expanding Circle is a suitable context for research on world Englishes and English as a lingua franca as well. Findings from the data analysis indicate that the use of comment markers among Korean speakers of English displays similar features with that of the Outer Circle varieties of English, especially East Asian varieties. Epistemic markers constitute the most sizable subcategory and the frequency of hearsay markers are relatively high raking the second in the data. The implications of the findings for the stylistic preferences and areal co-patterning are suggested. This paper contributes to the body of comment markers across the world Englishes.

High ratio DC-DC converter based on cascade modified Cuk converter topology

The proposal of a modified Cuk converter as the basic cell in the cascade topology, namely the cascade modified Cuk converter, has been conducted. A scheme for increasing the high voltage ratio using a cascade topology with 3 cells has been obtained, namely by increasing the source voltage to the total output voltage which includes the 3 cells. This will provide a higher voltage ratio than DC-DC converters that do not use cascade topology. In this study, a drop voltage expression due to non-idealities is derived. The voltage losses in the cascade condition will be high if there is an increase in the number of levels. Calculations and simulations on the proposed converter have also been conducted where the optimal duty cycle value is obtained in ideal and non-ideal conditions and the output voltage in both conditions. Experimental results have been given where non-ideal conditions give output voltage results close to the calculation and simulation values so that the duty cycle value becomes a reference in the design of the closed loop control system. Power loss fraction and efficiency have also been given so that efficiency optimization in the cascade modified Cuk circuit can be done to get high efficiency. The proposed closed loop control system has also been given where the control system uses a double-loop control scheme, namely the inner circle for current control and the outer circle for voltage control. Simulations and experiments have been given on the closed loop control system. It is found that the closed loop control system is fast, adaptive, and responsive. The contributions in this paper are to provide the results of simulation and experimental calculations, perform power loss analysis, propose a closed loop control system on the cascade topology, and provide expected results.

Demystifying the cultural representations in international high school English textbooks: a social-semiotic approach and teachers’ views

ABSTRACT Albeit cultural content in English textbooks have been much reported, little empirical evidence addresses global or international-distributed English textbooks. To fill this void, the present qualitative content analysis study aims to explore the representation of cultural content in international English textbooks used for Indonesian senior high school students. For another contribution, we also attempt to gain English teachers’ perceptions of cultural content in the textbooks examined through written interviews. Grounded in a social semiotic approach, the findings showcased that the textbooks’ content represents inner-circle countries in the aspect of perspectives, products, persons, and practices. Further, the imbalance in the cultural representation of the outer circle and expanding circle countries indicated that the authors do not sufficiently increase the global cultural awareness of English language learners because other cultural perspectives on varieties of English are not included. The interviews analysis revealed that the cultural contents were short and required improvement.

Development and Validation of Artificial Intelligence-Based Algorithms for Predicting the Segments Debulked by Rotational Atherectomy Using Intravascular Ultrasound Images

We develop and evaluate an artificial intelligence-based algorithm that uses pre-rotation atherectomy (RA) intravascular ultrasound (IVUS) images to automatically predict regions debulked by RA. A total of 2106 IVUS cross-sections from 60 patients with de novo severely calcified coronary lesions who underwent IVUS-guided RA were consecutively collected. The two identical IVUS images of pre- and post-RA were merged, and the orientations of the debulked segments identified in the merged images were marked on the outer circle of each IVUS image. The artificial intelligence model was developed based on ResNet (deep residual learning for image recognition). The architecture connected 36 fully connected layers, each corresponding to one of the 36 orientations segmented every 10°, to a single feature extractor. In each cross-sectional analysis, our artificial intelligence model achieved an average sensitivity, specificity, positive predictive value, negative predictive value, and accuracy of 81%, 72%, 46%, 90%, and 75%, respectively. In conclusion, the artificial intelligence-based algorithm can use information from pre-RA IVUS images to accurately predict regions debulked by RA and will assist interventional cardiologists in determining the treatment strategies for severely calcified coronary lesions.

Enacting a Global Englishes and Critical Pedagogy Integrated Curriculum in Korean High School English as a Foreign Language Classrooms

AbstractThis study examines the enactment of Global Englishes (GE) curriculum in public high school English as a foreign language classrooms in South Korea. Data collection involved pre‐ and post‐course surveys (N = 217, nine classrooms), students' written responses, and their oral presentations. The findings highlight the necessity of adopting a critical perspective as the initial step to incorporate GE in these classrooms. They also recommend integrating GE curriculum within the existing assessment framework. After curriculum enactment based on critical pedagogy and GE took place over the course of a year, the results from the post‐course survey indicated positive changes in students' receptiveness to GE, their perceptions of Outer Circle varieties, and their confidence in engaging in intercultural communication. Students' written responses also demonstrated an enhanced critical awareness of GE‐related issues. However, there was no significant change in their perceptions regarding the exclusion of GE in listening tests, their low preference for Expanding Circle varieties, and their limited multicultural communication skills. The pedagogical implications of this study are relevant not only for GE educators but also for those who enact locally driven curriculum innovations within test‐oriented contexts.
