Sur le plastique. Klänge de Wassily Kandinsky
Authors: Caliandro Stefania
Published: August 2023

L’article se propose de contribuer à l’exploration des logiques du sensible par une réflexion sur le plastique. L’œuvre Klänge de Wassily Kandinsky amène à observer comment la matière se façonne continuellement dans l’appréhension sensible, en supportant et accompagnant l’émergence de formes et figures, la création d’effets d’ambiance, mais en étayant aussi le retour à des valeurs et attraits proprement matériels. Recueil de poèmes et gravures où se déclenchent parfois des résonances entre le visuel et le langage verbal, Klänge est avant tout une œuvre qui exploite ce que l’artiste appelle sonorité, concept qu’il élabore à partir de l’usage poétique du mot et qu’il étend à la couleur et aux éléments picturaux, au-delà de tout ancrage référentiel. Le livre, contemporain, et peut-être même moteur, du passage à un art dit abstrait, est également une œuvre charnière pour entendre du tournant esthétique envisagé par l’artiste dans ses écrits théoriques. Il incite à une réflexion sur la plasticité, qui, en faisant fi de la délimitation de celle-ci à certains matériaux ou genres, dépasse aussi l’opposition entre l’abstrait et le figuratif, ou entre le plastique et l’iconique. Le plastique se tourne alors en concept-clé pour la compréhension de dynamiques morphologiques et permet de relever comment, dans la saisie, la matière est informée à divers degrés de figurabilité.
Modelagem cinemática dos sistemas de falhas e aplicação em casos de taludes naturais N030 e N040 da cidade do Salvador, Bahia, Brasil
Authors: Menezes Lucas de Santana , Corrêa-Gomes Luiz César
Published: August 2023

O processo desordenado de ocupação urbana em uma região de variação topográfica acentuada transformou a cidade do Salvador em uma das cidades brasileiras mais suscetíveis a movimentos de massa. Paralelamente, poucos são os trabalhos que analisam os sistemas de falhas presentes no substrato da cidade como condicionantes das rupturas de taludes. Este trabalho propôs um estudo baseado na realização de uma modelagem cinemática a partir de rede estereográfica igual-área (Schmidt-Lambert). Foram considerados como parâmetros um conjunto de taludes naturais N030 e N040, respectivamente relacionados com o Sistema de Falhas de Salvador (SFS) e o Sistema de Falhas do Iguatemi (SFI), e as principais estruturas rúpteis presentes na região. Essa modelagem foi aplicada no estudo de caso de 67 taludes próximos aos SFS e SFI, identificados através da interpretação de lineamentos morfoestruturais utilizando os dados geomorfométricos do projeto TOPODATA e por meio de seções transversais em mapa de curvas de nível da cidade do Salvador. Os dados obtidos pela modelagem cinemática viabilizaram a identificação de configurações de taludes suscetíveis aos mecanismos de ruptura associados às estruturas rúpteis descritas na região. O estudo de caso descreve seis locais em Salvador com presença de risco de movimento de massa por escorregamento em cunha e uma localidade onde o risco está relacionado com o mecanismo de tombamento. A divulgação desses dados permite tanto ao poder público quanto aos responsáveis técnicos por empreendimentos locais estabelecer um diagnóstico geotécnico mais acurado a respeito da estabilidade de taludes, com menor risco de prejuízos sociais e materiais.
A literacia midiática como ferramenta para amplificar a participação no jornalismo: um estudo de jovens universitários do ABC Paulista
Authors: Cunha Matheus Cestari , Santos Marli dos
Published: August 2023

Este artigo investiga a relação entre participação em conteúdos noticiosos e as competências midiáticas de jovens universitários. São consideradas essenciais a participação do público no jornalismo pós-industrial e as competências midiáticas do cidadão, segundo Celot e Perez-Tornero. Trata-se de recorte de um estudo mais amplo, no qual a abordagem é quali-quantitativa com a aplicação de questionário exploratório e entrevistas semiestruturadas com jovens universitários da região do ABC paulista. Identificou-se que a relação entre participação e competências midiáticas não está necessariamente explícita na contribuição e criação de conteúdos, porque as transformações do jornalismo contemporâneo e as manifestações do público abrangem tanto a produção quanto a disseminação de conteúdos.

Anthologies as Tools of Literary Hospitality
Authors: Rodríguez Guerrero-Strachan Santiago , Ibáñez José R.
Published: August 2023

This article examines the presence of Poe’s fiction in Spain, focusing on the reception of his anthologized short stories in the second half of the nineteenth century and the early twentieth century, and taking this as a case of literary hospitality that helped to develop the fantasy genre in the country. In the early decades of publication, collections of Poe’s short stories were generally introduced into Spain as translations of anthologies of Baudelaire’s French versions. These anthologies appealed to a broad readership and sold well, being published by both large, professional houses and smaller, family-run presses. Poe came to form part of the literary canon that was being shaped in the final decades of the nineteenth century in Spain, and was thus published alongside major literary figures, which attests to the kind of literary hospitality he enjoyed in Spain’s cultural world in the decades following his introduction into the country.
Culm anatomy of the genus Otatea (Poaceae, Bambusoideae, Bambuseae, Guaduinae) as a contribution to Mexican species identification
Authors: GARCÍA-MARTÍNEZ MIGUEL A. , TERRAZAS TERESA , SÁNCHEZ DANIEL , CARRILLO-REYES PABLO , RUIZ-SANCHEZ EDUARDO
Published: August 2023

Otatea is a Neotropical woody bamboo genus with thirteen described species. It is distributed from Mexico to Central America and northeastern Colombia. In Mexico, the archaeological evidence suggests that the culms of Otatea have been used for centuries by some ethnic groups. It is important to explore morphological and anatomical characters for species identification in woody bamboos as consequence of its monocarpic nature. Most studies on culm anatomy are centered on commercially used species describing their physical and mechanical properties. The aim of this work was to find culm anatomical characters with taxonomic value. To perform this, we collected internode samples from adult plants at mid culm of 15 specimens that represent 10 described species and two putative new species of Otatea. Our results include descriptions of culm anatomy at a cross section accompanied with images that detail all the structures measured and described. Additionally, we elaborate a key based on anatomical characters. This contribution is the first to explore culm anatomy of the genus Otatea in search for characters with taxonomic value, providing useful evidence for species identification, including samples from archaeological sites.

Published: August 2023

Two new species of Onychiuridae (Collembola) from Buryatia (Russia, East Siberia), Supraphorura chernovae sp. nov. and Thalassaphorura transbaikalica sp. nov., are herein described and illustrated. Supraphorura chernovae sp. nov. differs from its closest species, S. furcifera (Börner, 1901), by its dorsal pso formula as 32/022/23232, presence of 1 pso on the subcoxae 1 of all legs, and a larger set of vesicles on the PAO. Thalassaphorura transbaikalica sp. nov. is most similar to T. tibiotarsalis Sun, Chen & Deharveng, 2010 by the same dorsal pso formula (32/233/33343) and presence of 7 chaetae on the distal whorl of all tibiotarsi, but differs from the latter species specially by the presence of 1 pso on the subcoxa 1 of leg 1 (T. tibiotarsalis has 2 pso), number of vesicles on the PAO (13–14 vs. 17–18), number of chaetae on the subcoxa 1 of legs 1–3 (4, 4, 4 vs. 3, 3, 3), and ratio of the empodial appendage and claw (0.8–0.9 vs. 0.5). After our study there are now 47 recorded species of Onychiuridae recorded from East Siberia.

Roth (Poaceae), is distributed in Europe and the Asian part of Russia, while D. altithermella (Walsingham, 1903) was only recorded in Europe with host plant unknown. Here, we report Dactylotula for the first time in China represented by a new leaf-mining species described herein as D. phragmitella, sp. n., feeding on Phragmites australis (Cav.) Steud. (Poaceae). Most of the specimens were collected in the Yellow River Delta. Photos of the adult, wing venation, male and female genitalia, host plant, leaf mines and parasitoid wasps of the new species are provided. Additionally, DNA barcodes of the new species are provided and discussed along sequences of the other two congeneric species.
Seasonal Storm Characteristics Govern Urban Flash Floods: Insights from the Arid Las Vegas Wash Watershed
Authors: Yu Guo , Hatchett Benjamin J. , Miller Julianne J. , Berli Markus , Wright Daniel B. , Mejia John F.
Published: August 2023

In the arid and semiarid southwestern United States, both cool- and warm-season storms result in flash flooding, although the former storms have been much less studied. Here, we investigate a catalog of 52 flash-flood-producing storms over the 1996–2021 period for the arid Las Vegas Wash watershed using rain gauge observations, reanalysis fields, radar reflectivities, cloud-to-ground lightning flashes, and streamflow records. Our analyses focus on the hydroclimatology, convective intensity, and evolution of these storms. At the synoptic scale, cool-season storms are associated with open wave and cutoff low weather patterns, whereas warm-season storms are linked to classic and troughing North American monsoon (NAM) patterns. At the storm scale, cool-season events are southwesterly and southeasterly under open wave and cutoff low conditions, respectively, with long duration and low to moderate rainfall intensity. Warm-season storms, however, are characterized by short-duration, high-intensity rainfall, with either no apparent direction or southwesterly under classic and troughing NAM patterns, respectively. Atmospheric rivers and deep convection are the principal agents for the extreme rainfall and upper-tail flash floods in cool and warm seasons, respectively. Additionally, intense rainfall over the developed low valley is imperative for urban flash flooding. The evolution properties of seasonal storms and the resulting streamflows show that peak flows of comparable magnitude are “intensity driven” in the warm season but “volume driven” in the cool season. Furthermore, the distinctive impacts of complex terrain and climate change on rainfall properties are discussed with respect to storm seasonality.

Published: August 2023

The low-temperature plasma (LTP) probe is a common plasma-based source used for ambient desorption–ionization mass spectrometry (MS). While the LTP probe has been characterized in detail with MS, relatively few studies have used optical spectroscopy. In this paper, two-dimensional (2D) imaging at selected wavelengths is used to visualize important species in the LTP plasma jet. First, 2D steady-state images of the LTP plume for N2+ (391.2 nm), He I (706.5 nm), and N2 (337.1 nm) emissions were recorded under selected plasma conditions. Second, time-resolved 2D emission maps of radiative species in the LTP plasma jet were recorded through the use of a 200 ns detection gate and varying gate delays with respect to the LTP trigger pulse. Emission from He I, N2+, and N2 in the plasma jet region was found to show a transient behavior (often referred to as plasma bullets) lasting only a few microseconds. The N2+ and He I maps were highly correlated in spatial and temporal structure. Further, emission from N2 showed two maxima in time, one before and one after the maximum emission for N2+ and He I, due to an initial electronic excitation wave and ion–electron recombination, respectively. Third, the interaction of the LTP probe with a sample substrate and an electrically grounded metallic needle was studied. Emission from a fluorophore on the sample substrate showed an initial photon-induced excitation from plasma-generated photons followed by electronic excitation by other plasma species. The presence of a grounded needle near the plasma jet significantly extended the plasma jet lifetime and also generated a long-lived corona discharge on the needle. The effect of LTP operating parameters on emission spectra was correlated with mass-spectral results including reagent-ion signals. Lastly, five movies provide a side-by-side comparison of the temporal behavior of emitting species and insights into the interactions of the emission clouds with a sample surface as well as an external needle. Temporally and spatially resolved imaging provided insights into important processes in the LTP plasma jet, which will help improve analyte ion sampling in LTP–MS.
First-Order Individual Gas Sensors as Next Generation Reliable Analytical Instruments

Published: August 2023

It is conventionally expected that the performance of existing gas sensors may degrade in the field compared to laboratory conditions because (i) a sensor may lose its accuracy in the presence of chemical interferences and (ii) variations of ambient conditions over time may induce sensor-response fluctuations (i.e., drift). Breaking this status quo in poor sensor performance requires understanding the origins of design principles of existing sensors and bringing new principles to sensor designs. Existing gas sensors are single-output (e.g., resistance, electrical current, light intensity, etc.) sensors, also known as zero-order sensors (Karl Booksh and Bruce R. Kowalski, Analytical Chemistry, DOI: 10.1021/ac00087a718). Any zero-order sensor is undesirably affected by variable chemical background and sensor drift that cannot be distinguished from the response to an analyte. To address these limitations, we are developing multivariable gas sensors with independent responses, which are first-order analytical instruments. Here, we demonstrate self-correction against drift in two types of first-order gas sensors that operate in different portions of the electromagnetic spectrum. Our radiofrequency sensors utilize dielectric excitation of semiconducting metal oxide materials on the shoulder of their dielectric relaxation peak and achieve self-correction of the baseline drift by operation at several frequencies. Our photonic sensors utilize nanostructured sensing materials inspired by Morpho butterflies and achieve self-correction of the baseline drift by operation at several wavelengths. These principles of self-correction for drift effects in first-order sensors open opportunities for diverse emerging monitoring applications that cannot afford frequent periodic maintenance that is typical of traditional analytical instruments.
‘East of Suez’ and the ‘Indo-Pacific’ in British Politics: Some Lessons of History
Authors: Pearce Nick
Published: August 2023

The idea of a transoceanic ‘Indo-Pacific’ region has a long historical lineage in British political thought and practice, one whose roots lie in processes of imperial colonisation, conquest and trade in Asia and Australasia. Recent discourses of a return ‘East of Suez’ and the UK's ‘Indo-Pacific Tilt’ cannot be understood as mere imperial nostalgia or post-imperial over-reach, however. Instead, there are historical political imaginaries of Britain's global role which are being put to work in the contemporary politics of shaping an Indo-Pacific strategy for the UK. British policy in the Indo-Pacific has been marked by a consistent awareness of multi-polarity and strategic vulnerability, hierarchies of alliances that give a privileged place to the US and the countries of the ‘Anglosphere’, and the recurrence of maritime, ‘blue water’ conceptions of British identity and interests. These are now being tested by the war in Ukraine and other developments.
Astronomical observations in Bologna, Montpellier, and Genoa in the early 14th century: Iohannes de Luna Theutonicus revisited
Authors: Nothaft C. Philipp E.
Published: August 2023

MS Vienna, Österreichische Nationalbibliothek, 5311, fol. 137r, contains an unusual record of astronomical observations, among which are measurements of solar and stellar altitudes carried out with large quadrants in Bologna, Montpellier, and Genoa between 1305 and 1312. An analysis of this observational data reveals a high level of precision and accuracy, as the astronomer responsible achieved a mean error of only 0;2° during an extended run of measurements of solar noon altitudes made between December 1305 and March 1306. Other passages on the same manuscript page mention Johannes de Luna, a German astrologer-astronomer active in Bologna between c.1299 and 1312. References to his name in 14th-century manuscripts shed light on his involvement in contemporary attempts to correct the Toledan Tables and revise their model of precession on an observational basis.
College Student Video Gaming: Risk or Resilience for Mental Health?
Authors: Vengurlekar Ishan N. , Thudi Koushik R.
Published: August 2023

Video gaming has become a popular method of entertainment for college students. Previous work indicates mixed results regarding the link between video gaming and mental health outcomes. However, little research has addressed how different genres of video games might produce various mental health outcomes. The current study examined whether video game genre enjoyment moderated the links between time spent playing video games and anxiety and stress in college students. College students responded to measures assessing various components of mental health indicating their engagement with various genres of video games. Results indicated no evidence of moderation in all genres of video games. The only significant association to emerge was that of time spent playing life simulation games and anxiety. Our findings demonstrate a minimal influence of video gaming on stress and anxiety levels among college students. Discussed are rationales for the null results and future directions for video game focused research.
Research on route planning for solar UAV based on the intelligent optimization algorithm
Authors: Hu Zhonghua , Liu Shihao
Published: August 2023

The solar unmanned aerial vehicle (UAV) route planning needs to comprehensively consider the conversion efficiency of solar cells under the influence of solar ground reflection radiation and sky scattering radiation. On the one hand, it is necessary to consider the cost of radar threat, mileage energy consumption, mountain impact and other costs. On the other hand, it is also necessary to consider the influence of high threat, mountain shadow occlusion cost, and cloud shading cost on solar photovoltaic conversion efficiency. The above problem was solved through using the ant colony intelligent optimization algorithm. By constructing ant colony paths rationally, models of mountain impact cost, high threat, mountain shadow shelter cost, and cloud shading cost were established. The constraints such as the maximum action distance, solar irradiation angle and effective action distance of various costs were introduced into the cost model and exploration factor calculation, and the comprehensive optimization problem of solar UAV route was solved. Finally, the simulation results show that the algorithm path structure is reasonable; the target node can be found independently; the convergence speed can meet the requirements of route planning; the generated route cost is small; the algorithm is reasonable and effective.
Objective Tinnitus of Nasopharyngeal Origin
Authors: Kim Ki-Won , Lee Gilmoon , Choi Ick Soo , Lee Jeon Mi
Published: August 2023

We report a rare case of objective tinnitus induced by nasopharyngeal muscle constriction. A 49-year-old female patient presented at the clinic with unintentional sounds coming from the nasal cavity while talking or swallowing, which were similar to the lip-smacking sound. Physical examination revealed a hypertrophic posterior nasopharyngeal wall and torus tubarius at rest. With voluntary effort, the posterior pharyngeal wall protruded prominently and collided with the torus tubarius on either side, generating a sound when they were separated. Botox injection was recommended but the patient refused. The diagnosis and treatment of objective tinnitus are well established, but in some cases, it may occur under unexpected conditions. We report a novel type of objective tinnitus. A thorough physical examination for tinnitus could reveal the cause.

Authors: Wang Meng , Hua Yuwen , Chen Ya , Qian Jing , Pang Lianfu
Published: August 2023

With the continuous development of information technology, information literacy education is becoming more and more important for university students. However, information literacy education in Chinese universities is still in the development stage and the cultivation effect needs to be improved. Therefore, this study takes the teaching of Information Retrieval as an example, based on constructivist learning theory and social exchange theory, reveals the influential factors related to the cultivation effect and explores the causal rela-tionship between each variable and the cultivation effect through a qualitative comparative analysis research method with a configura-tion perspective. This study finds that university students in information literacy education can be classified into four categories: context-driven, class-guidance, meaning-realised and motivation satisfaction. For these four types of university students, this study proposes corresponding countermeasures for information literacy cultivation in order to enhance the effectiveness of cultivation.

School Health Teachers as Partners in Diabetes Caring: Maternal Perspectives
Authors: Uhm Ju-Yeon , Choi Mi-Young
Published: August 2023

Background:

The absence of primary care providers’ participation in school health care may require close collaboration between school health teachers and parents. This study explores maternal perspectives on obstacles and improvements in partnerships with school health teachers of children with type 1 diabetes.

Methods:

Participants were recruited using purposive sampling through an online type 1 diabetes self-help group in South Korea. Twenty-two mothers whose children were aged between 7 and 13 and had been diagnosed with type 1 diabetes at least 1 year ago were included. Individual interviews were conducted based on a semi-structured interview guide from February to June 2019. Qualitative data were analyzed using inductive content analysis comprising open coding, coding sheets, grouping, categorization, and abstraction.

Results:

Mothers recognized obstacles in eight categories and improvements in nine categories under institutional, interpersonal, and intrapersonal aspects of the partnership with school health teachers. Respondents recognized insufficient legal coverage and guidelines, and also health teacher shortage and workload as obstacles in the institutional dimension. Mothers perceived building trust, compromising to balance responsibilities, and constant and open communication as improvements in the interpersonal dimension. They recognized practical competency and tailored care for ordinary school life as school health teacher-related improvements.

Conclusions:

The findings indicate that school health teachers should compromise to balance responsibilities to improve partnerships with parents in the school health care setting. Institutional improvements, such as establishing robust laws and clear guidelines and increasing the number of school health teachers, should be prioritized.
Technology-enhanced creativity in K-12 music education: A scoping review
Authors: Lam Chi Kai
Published: August 2023

This scoping review addresses internationally published empirical studies on the subject of technology-enhanced creativity. The study aims to identify the types of technological tools used to enhance students’ creativity and examine how technological tools can support students’ creativity in K-12 music education. This review selected and analyzed 17 studies published from 1987 to 2022 in peer-reviewed journals using a rigorous five-stage scoping framework. Data extraction and analysis were conducted in Covidence. The results revealed eight types of technological tools used to enhance creativity in the music classroom, in which sequencer software and GarageBand were the most commonly used type of technological tools and applications respectively. Technology’s support for creativity was also discussed from the perspectives of Lubart’s four roles of computers: (a) computer as nanny, (b) computer as pen-pal, (c) computer as coach, and (d) computer as colleague. The results showed a dearth of research on how technology can become students’ partners to help them generate creative ideas. Based on the findings, this review concluded with implications and recommendations for future research.
Forgotten Stories of Yogurt: Cultivating Multispecies Wisdom
Authors: Mutlu Sirakova Sevgi
Published: August 2023

Thanks to recent human microbiome research, we are gradually gaining a better understanding of the vital role that microbial diversity plays in health and well-being. However, as industrial food production standardizes fermented foods—making monoculture “probiotics”—we risk losing both microbial diversity and the cultural heritage of how to sustain it. This article takes yogurt as a case study to explore the ongoing disappearance of microbial biodiversity and its relationship to food practices. As an ancient fermentation product, yogurt has a rich biocultural heritage that is reflected in its diverse preparation methods—including, as this article describes, using ants and spring rain. I employed autoethnography as a form of qualitative inquiry to trace the stories of yogurt passed down through generations in my community from the Rhodope Mountains. Here multispecies and sensory approaches allowed me to delve into the intimate cultural and personal aspects of yogurt making. The stories I gathered from Bulgaria and Turkey reveal the richness of interspecies and sensorial connections involved in yogurt production. I argue that these practices cultivate diverse multispecies relationships and provide valuable insights into the broader loss of biocultural diversity. This article is thus an invitation to reflect on the ways in which the contemporary biodiversity crisis is related to the loss of local cultural knowledge, skills, and wisdom that have long nurtured diverse and generative multispecies relationships.
Radiomics analysis of pericoronary adipose tissue based on plain CT for preliminary screening of coronary artery disease in patients with type 2 diabetes mellitus
Authors: Chen Meng , Hu Jingcheng , Chen Can , Hao Guangyu , Hu Su , Xu Jialiang , Hu Chunhong
Published: August 2023

Background

Type 2 diabetes mellitus (T2DM) is associated with a markedly increased prevalence of coronary artery disease (CAD). Radiomics features of pericoronary adipose tissue (PCAT) were correlated with inflammation, which may have potential value in the prediction of CAD.

Purpose

To determine whether radiomics analysis of PCAT captured by plain computed tomography (CT) could predict obstructive CAD in patients with T2DM.

Material and Methods

The study included 155 patients with T2DM with suspected CAD between January 2020 and December 2021. Volumes of right coronary artery of 10–50 mm were delineated in the plain CT to extract radiomics features and PCAT CT attenuation (PCATa). Least absolute shrinkage and selection operator was used to select the useful radiomics features to calculate the radiomics score (Rad-score). Univariate and multivariable logistic regression were applied to select independent predictors. The predictive performance was evaluated by the area under the receiver operating characteristics curve (AUC).

Results

Rad-score (per 0.1 increments: odds ratio [OR] = 1.297; P < 0.001), coronary artery calcium score (CACS) (OR = 1.003; P = 0.037), and sex (OR = 3.245; P = 0.026) were identified as independent predictors for obstructive CAD. Rad-score (AUC = 0.835) outperformed CACS (AUC = 0.780), sex (AUC = 0.665), and PCATa (AUC = 0.550) in predicting obstructive CAD ( P = 0.017 and 0.003 for Rad-score vs. sex and PCATa, respectively); however, the improvement between Rad-score and CACS had no statistical significance ( P = 0.490).

Conclusion

Plain CT-derived Rad-score may be used as a preliminary screening tool for obstructive CAD in patients with T2DM.
Errors in clinical diagnosis: a narrative review
Authors: Vally Zunaid Ismail , Khammissa Razia A.G. , Feller Gal , Ballyram Raoul , Beetge Michaela , Feller Liviu
Published: August 2023

Diagnostic errors are often caused by cognitive biases and sometimes by other cognitive errors, which are driven by factors specific to clinicians, patients, diseases, and health care systems. An experienced clinician diagnoses routine cases intuitively, effortlessly, and automatically through non-analytic reasoning and uses deliberate, cognitively effortful analytic reasoning to diagnose atypical or complicated clinical cases. However, diagnostic errors can never be completely avoided. To minimize the frequency of diagnostic errors, it is advisable to rely on multiple sources of information including the clinician’s personal experience, expert opinion, principals of statistics, evidence-based data, and well-designed algorithms and guidelines, if available. It is also important to frequently engage in thoughtful, reflective, and metacognitive practices that can serve to strengthen the clinician’s diagnostic skills, with a consequent reduction in the risk of diagnostic error. The purpose of this narrative review was to highlight certain factors that influence the genesis of diagnostic errors. Understanding the dynamic, adaptive, and complex interactions among these factors may assist clinicians, managers of health care systems, and public health policy makers in formulating strategies and guidelines aimed at reducing the incidence and prevalence of the phenomenon of clinical diagnostic error, which poses a public health hazard.
State action and inaction in the shaping of value and wealth entanglements: The role of Singapore in the global ‘gold chain’

Published: August 2023

Value and wealth creation, capture and protection are important features of contemporary global capitalism. However, global value chains and global wealth chains have been studied mostly in isolation from each other. In this article, we address this limitation by revealing the entanglements of value and wealth in the gold sector. We develop a typology of state action and inaction in value and wealth chains to explain how the state shapes the mobilisation and management of tangible and intangible assets. In our empirical analysis, we chronicle the creation of a ‘gold hub’ in Singapore that pulls together value and wealth functions, and highlight the various roles of the Singaporean state – as facilitator, deregulator-cum-redistributor, and direct actor. We show that entanglements of value and wealth are shaped by specific configurations of state action and inaction, and are built upon intangible dimensions of legal affordance and cultural practice coupled with very tangible facilities and infrastructure. Our analysis pinpoints the co-dependence of value creation and wealth protection systems as vital to processes of accumulation.
Statistical analysis and modeling of wrinkle defects in continuous-fiber composite forming processes
Authors: Yang Yunpei , Colton Jonathan
Published: August 2023

Wrinkles are detrimental to the performance of composite components. The prediction of wrinkling during forming is challenging because of complex material interactions. Current computational modeling methods are capable of wrinkle prediction but only for one given set of parameters per simulation cycle. To improve the prediction of wrinkles, this article presents a theory that correlates wrinkle formation with factors such as composite layup and part dimension. This theory allows one to perform design of experiments for physical or virtual forming tests and obtain binomial probability distributions capable of wrinkle prediction. The theory is validated with forming experiment data and demonstrates its potential in wrinkle prediction.

Diabetic wounds impose enormous distress and financial burden on patients, and finding effective dressings to manage wounds is critical. As a Chinese herbal medicine with a long history of Clinical application, Bletilla striata has significant medicinal effects in the therapy of various wounds. In this study, PLA and the pharmacodynamic substances of Bletilla striata were prepared into fibrous scaffolds by emulsion electrospinning technology for the management of diabetic wounds in mice. The results of scanning electron microscopy showed that the core-shell structure fibre was successfully obtained by emulsion electrospinning. The fibre membrane exhibited excellent water absorption capability and water vapor transmission rate, could inhibit the growth of Staphylococcus aureus and Pseudomonas aeruginosa, had good compatibility, and achieved excellent healing effect on diabetic wounds. Especially in the in vivo wound healing experiment, the wound healing rate of composite fibre membrane treatment reached 98.587 ± 2.149% in 16 days. This work demonstrated the good therapeutic effect of the developed fibrous membrane to diabetic wound, and this membrane could be potentially applied to chronic wound healing.

Atomic substitution or doping of a bioceramic material hydroxyapatite (HA) with specific ions is an appealing approach for improving its biocompatibility and activity, as well as imparting antibacterial properties. In this study, selenium- and/or copper-substituted hydroxyapatite powders were synthesized by an aqueous precipitation method and using the freeze-drying technique. The molar concentrations of constituents were calculated based on the proposed mechanism whereby selenium (Se4+) ions partially substitute phosphorus (P5+) sites, and copper (Cu2+) ions partially substitute (Ca2+) sites in the HA lattice. Dried precipitated samples were characterized using Inductively coupled plasma optical emission spectroscopy (ICP-OES), X-ray diffraction analysis (XRD), Fourier-transform infrared spectroscopy (FTIR) and Field-emission scanning electron microscopy with energy dispersive X-ray spectroscopy (FESEM-EDX). Accordingly, substitution of Se4+ and/or Cu2+ ions took place in the crystal lattice of HA without the formation of any impurities. The presence of sulphur (S2-) ions in the hydroxyapatite was detected by ICP-OES in all samples with copper substituted in the lattice. The cytotoxicity of the powders on osteoblastic (MC3T3-E1) cells was evaluated in vitro. Selenium substituted hydroxyapatite (SeHA), at the concentration (200 μg/mL), demonstrated higher populations of the live cells than that of control (cells without powders), suggesting that selenium may stimulate the proliferation of these cells. In addition, the copper substituted hydroxyapatite (CuHA) and the selenium and copper substituted hydroxyapatite (SeCuHA) at the concentrations (200 and 300 μg/mL) and (200 μg/mL), respectively demonstrated better results than the unsubstituted HA. Antimicrobial activity was assessed using a well-diffusion method against Streptococcus mutans and Candida albicans, and superior results has obtained with SeCuHA samples. Presented findings imply that selenium and/or copper substituted modified hydroxyapatite nanoparticles, may be an attractive antimicrobial and cytocompatible substrate to be considered for use in a range of translational applications.

Published: August 2023

In this study, composite materials with Al6061 alloy matrix and B4C particles reinforcement were produced by hot extrusion process. Fabricated composites were examined for the mechanical and machinability attributes. Al6061 alloy powders (<100 µm) and B4C particles (<10 µm) were mixed with the different weight fraction of B4C (3%, 6%, and 9% by weight) of and then cold pressed under 200 MPa pressure. The cold pressed powder metal block was extruded hot after preheating at 550°C for 1 h. Further, the composites were subjected to T6 aging heat treatment after hot extrusion. Microstructure, density, hardness, tensile strength, and wear properties were examined. The effects of cutting speed and cutting force on the machinability were also investigated. In addition, surface roughness and chips formation were examined. High density (99.6%) values were achieved with the extrusion process. With increasing B4C particles ratio, the hardness and tensile values were increased which was substantiated by the fracture morphology of the tensile specimens. It has been observed that tool smearing was high in the machining of the low-reinforced (3% B4C) composite. The highest cutting force was measured as 236 N at a feed rate of 0.27 mm/rev and a cutting speed of 250 m/min. It has also been observed that the average surface roughness decreased with increasing cutting speed and it increased with increasing feed rate.

Impact of Perceived Organizational Support on Turnover Intention in Luxury Hotels: The Mediating Role of the Perceived Value of Artificial Intelligence
Authors: Li Yanan , Khan Muhammad Shahid
Published: August 2023

The hotel industry’s artificial intelligence (AI) technology has increasingly become a topic of concern in academia and business circles. At the same time, scholars pay more and more attention to how AI technology affects employee turnover intention (TI). The current research empirically tested the impact of perceived organizational support (POS) on TI from the perspective of employees’ perceived value of AI (PVAI). The data were collected from the in-service employees of five-star rated ‘luxury’ hotels in 28 provinces of China through questionnaires and then analysed using Smart PLS (4.0) software using the structural equation method. The results show that POS has a significant effect on employees’ TI (compared with FPOS, CPOS and APOS are more prominent), POS has a significant effect on PVAI from employees, PVAI has a significant effect on employees’ TI and plays a significant mediating role (the effect size is 50.557%) between POS and TI in luxury hotels. This study is the first to propose a conceptual model with the PVAI as the mediator and verify its rationality, which has generated significant theoretical, methodological and managerial contributions for luxury hotels in the application of AI technology.
