Chinese red panda (Ailurus styani) has stable individual-level laterality of anogenital rubbing
Authors: Lin Yi , Liu Qunxiu , Song Ningning , Zhang Endi , Chen Min
Published: September 2021

Behavioural laterality was widely discovered in both vertebrates and invertebrates. However, reports of behavioural laterality in scent-marking are scarce and focused on limb preference during scent-marking. In this study, we observed another scent-marking behaviour, anogenital rubbing, which involved whole-body movement, in zoo-housed Chinese red pandas. We recorded the moving direction of the buttocks when initiating anogenital rubbing. Our results showed that three of our subjects were explicitly left-biased when initiating anogenital rubbing and the other one showed more left initiation although there was no statistical significance. Besides, the laterality was consistent across the whole observational period. This is the first report of laterality in anogenital rubbing, perhaps indicating hemispheric specialization for chemical communication in the Chinese red panda.
Branding Salafism: Salafi Missionaries as Social Media Influencers
Authors: Sorgenfrei Simon
Published: September 2021

This article analyses the social media activity of Swedish Salafi missionaries in the light of theories about influencer marketing and branding. Making use of source material from the Instagram accounts of the preacher Anas Khalifa and the preachers Abdulwadud Frank, Abdullah as-Sueidi, and Moosa Assal, the last three of whom are associated with the organisation Islam.nu, this article investigates how social media can be used as tools for missionary endeavours, how Salafism might be branded on Instagram, and how religious authority and authenticity are fashioned online.
Regreening of The Northern Ethiopian Mountains: Effects on Flooding and on Water Balance
Authors: Asfaha Tesfaalem G. , De Meyere Michiel , Frankl Amaury , Haile Mitiku , Nyssen Jan
Published: September 2021

The hydro-geomorphology of mountain catchments is mainly determined by vegetation cover. This study was carried out to analyse the impact of vegetation cover dynamics on flooding and water balance in 11 steep (0.27-0.65 mm-1) catchments of the western Rift Valley escarpment of Northern Ethiopia, an area that experienced severe deforestation and degradation until the first half of the 1980s and considerable reforestation thereafter. Land cover change analysis was carried out using aerial photos (1936,1965 and 1986) and Google Earth imaging (2005 and 2014). Peak discharge heights of 332 events and the median diameter of the 10 coarsest bedload particles (Max10) moved in each event in three rainy seasons (2012-2014) were monitored. The result indicates a strong reduction in flooding (R2 = 0.85, P<0.01) and bedload sediment supply (R2 = 0.58, P<0.05) with increasing vegetation cover. Overall, this study demonstrates that in reforesting steep tropical mountain catchments, magnitude of flooding, water balance and bedload movement is strongly determined by vegetation cover dynamics.
Mediating Matonge: Relocations of Belgian Postcoloniality in Four Films
Authors: Arnaut Karel
Published: September 2021

In this paper I look at the Matonge neighbourhood of Brussels as a locus of postcolonial and diasporic imagination and activism by different groups and individuals most notably people who identify as Africans, Belgians with African roots, or ‘Black’ in Belgium. Within a longer historical narrative that starts in the late 19th century, I focus on the period beginning in the late 1980s when new migrational flows from Africa and other southern countries into Brussels make the Matonge quarter increasingly visible in an otherwise hesitantly globalizing Belgian/European metropolis. This issue is taken up by several filmmakers who, over the last thirty years, have situated their critiques of the Belgian postcolonial condition in ‘Matonge’. In this paper I briefly present four of these films in order to illustrate the ways in which ‘Matonge’ features in changing discourses concerning inequality, cultural affirmation, and diasporic activism.
Orality, Memory and the New African Diaspora Poetry: Examining Tanure Ojaide’s Poetics
Authors: Odueme Edoama Frances
Published: September 2021

The influence of traditional oral poetic forms on modern African poetry has been significant. Fascinated by oral forms which their respective communities relied on (to inform, teach, and correct erring members) before the advent of literacy, modern African writers borrow from these oral traditions and blend them with the features of the written Western literary forms. This appropriation of the oral poetic techniques by modern African poets continues today, as is clearly evident in the writings of many contemporary African poets, whose scripted works are seen to have drawn much in terms of content and form from the African oral poetic tradition. Following in this trend, the new African diaspora poets have also maintained the practice of skillfully blending the rich African verbal art and the modern (written) poetic forms to articulate the experiences of their African homeland as well as those of the diaspora, in order to construct and project their identities and visions of a new life in their lived world. In order to explore how through recourse to memory, “new African diasporas” (African-descended people who migrated out of Africa, during the postcolonial era and who live and practice their art outside the African homeland) utilize African oral art techniques in their writings, this essay analyses the poetry of Tanure Ojaide.

Published: September 2021

Maize lethal necrosis (MLN) disease caused by a combined infection of Maize chlorotic mottle virus (MCMV) and any cereal infecting potyvirus is a threat to food security in Sub-Saharan Africa (SSA). Resistance to potyvirus has been extensively studied and Mdm1 gene for potyvirus resistance on chromosome 6 of maize is linked to Y1 gene for maize endosperm colour. This study is aimed at selecting for coupling-phase recombination of potyvirus resistance and white endosperm colour. White susceptible maize lines CML333 and CML277 were crossed with a yellow resistant line, Pa405, to produce F1 and F2 progenies. Progenies were screened using molecular markers to recover 22 white endosperm recombinants. 22 selections were advanced to F3 recombinant families, and 10 were assayed for their responses to Maize dwarf mosaic virus (MDMV) and Sugarcane mosaic virus (SCMV). Four families segregated for SCMV resistance, selection of homozygous recombinants within these families will provide lines appropriate for improving lines with resistance to SCMV and MLN resistance in SSA.
Yield Stability and Farmer Preference of Cowpea (Vigna Unguiculata) Lines in Semi-Arid Eastern Kenya
Authors: Kuruma Rose Wangari , Sheunda Patrick , Kahwaga Charles Muriuki
Published: September 2021

Stability in yields of agronomically acceptable cultivars is generally regarded as the ultimate goal in cowpea improvement. Nine advanced cowpea lines and 3 local checks were evaluated for grain yield in eastern Kenya with the aim of identifying stable genotypes and integrating farmer preferences. The study was conducted in 3 locations over 2 years under a randomized complete block design with 3 replications. Stability was estimated using additive main effects and multiplicative interaction (AMMI) and genotype by environment (GGE) models. There was variation among genotypes, locations and their interactions for grain yield. Genotype G5, G9 and G2 were found to be stable and high yielding. Environments Kit16 and Kit15 were considered as the most suitable for selecting superior genotypes for adaptability and stability. Farmers’ criteria for selecting genotypes included early maturing, pod length, disease tolerant and high yielding varieties. Cowpea performance for grain yield was greatly influenced by inherent genotypic factors, environment and their interaction effects.

Three new species of Androdeloscia Leistikow, 1999 (Oniscidea: Philosciidae) from the Brazilian Amazonia
Authors: GRANGEIRO DANIELA CORREIA , SOUZA LEILA APARECIDA , CHRISTOFFERSEN MARTIN LINDSEY
Published: September 2021

Three new species of Androdeloscia Leistikow, 1999 from the Brazilian Amazonian rainforest are described. Androdeloscia bicornuata sp. nov., A. paraleilae sp. nov., and A. micropunctata sp. nov. were distinguished from the 26 other species of the genus mainly based on the shape of male pleopod I endopod. Androdeloscia bicornuata sp. nov. differs from all the species in the genus by the complex morphology of the distal portion of the male pleopod I endopod bearing hyaline lamella and two horn-like tips. Androdeloscia paraleilae sp. nov. is characterized by the male pleopod I endopod with simple distal portion, without hyaline lamella, and apex represented by a curved tip and inner margin serrate proximally; and by the concavity on the lateral margin of the first maxilla (except for the A. leilae that is related to other listed characteristics). Androdeloscia micropunctata sp. nov. differs from the remaining species of the genus by the male pleopod I endopod with simple distal portion, without hyaline lamella, and apex truncate bearing a small acute tip in the outer corner; and 5+5 teeth on the first maxilla. Some characters related to the genus are later discussed.
Excitation of the Madden–Julian Oscillation in Atmospheric Adjustment to Equatorial Heating
Authors: Liang Yu , Fedorov Alexey V. , Zeitlin Vladimir , Haertel Patrick
Published: September 2021

We study the adjustment of the tropical atmosphere to localized surface heating using a Lagrangian atmospheric model (LAM) that simulates a realistic Madden–Julian oscillation (MJO)—the dominant, eastward-propagating mode of tropical intraseasonal variability modulating atmospheric convection. Idealized warm sea surface temperature (SST) anomalies of different aspect ratios and magnitudes are imposed in the equatorial Indian Ocean during MJO-neutral conditions and then maintained for 15 days. The experiments then continue for several more months. Throughout these experiments, we observe a robust generation of an MJO event, evident in precipitation, velocity, temperature, and moisture fields, which becomes a key element of atmospheric adjustment along with the expected Kelvin and Rossby waves. The MJO circulation pattern gradually builds up during the first week, and then starts to propagate eastward at a speed of 5–7 m s−1. The upper-level quadrupole circulation characteristic of the MJO becomes evident around day 14, with two anticyclonic gyres generated by the Gill-type response to convective heating and two cyclonic gyres forced by the excited Kelvin waves and extratropical Rossby wave trains. A moisture budget analysis shows that the eastward propagation of the MJO is controlled largely by the anomalous advection of moisture and by the residual between anomalous moisture accumulation due to converging winds and precipitation. The initial MJO event is followed by successive secondary events, maintaining the MJO for several more cycles. Thus, this study highlights the fundamental role that the MJO can play in the adjustment of the moist equatorial atmosphere to localized surface heating.
Should I Stay or Should I Go? South Indian Artisanal Fishers’ Precarious Livelihoods and Their Engagement with Categorical Ocean Forecasts

Published: September 2021

Ocean State Forecasts contribute to safe and sustainable fishing in India, but their usage among artisanal fishers is often limited. Our research in Thiruvananthapuram district in the southern Indian state of Kerala tested forecast quality and value and how fishers engage with forecasts. In two fishing villages, we verified forecast accuracy, skill, and reliability by comparing forecasts with observations during the 2018 monsoon season (June–September; n = 122). We assessed forecast value by analyzing fishers’ perceptions of weather and risks and the way they used forecasts based on 8 focus group discussions, 20 interviews, conversations, and logs of 10 fishing boats. We find that while forecasts are mostly accurate, inadequate forecasting of unusual events (e.g., wind >45 km h−1) and frequent fishing restrictions (n = 32) undermine their value. Fishers seek more localized and detailed forecasts, but they do not always use them. Weather forecasts are just one of the tools artisanal fishers deploy, used not simply to decide as to whether to go to sea but also to manage potential risks, allowing them to prepare for fishing under hazardous conditions. Their decisions are also based on the availability of fish and their economic needs. From our findings, we suggest that political, economic, and social marginality of south Indian fishers influences their perceptions and responses to weather-related risks. Therefore, improving forecast usage requires not only better forecast skill and wide dissemination of tailor-made weather information, but also better appreciation of risk cultures and the livelihood imperatives of artisanal fishing communities.
Up-Conversion Luminescence Processes in NaLaF4 Doped with Tm3+ and Yb3+ and Dependence on Tm3+ Concentration and Temperature
Authors: Grube Jurgis
Published: September 2021

In this work, luminescence processes in polycrystalline NaLaF4:Tm3+ and NaLaF4:Tm3+,Yb3+ materials were studied. Luminescence spectra and decay kinetics measurements were performed for NaLaF4 doped with various Tm3+ concentrations (0.01, 0.1, 0.5, 1, and 2 mol%) under direct excitation to 3P0, 1D2, 1G4, and 3H4 states. It was found that some of the Tm3+ excited states are more affected by Tm3+ concentration than other states. Under infrared excitation of Yb3+, energy transfer to Tm3+ occurred and intensive ultraviolet and blue up-conversion luminescence was observed. Possible up-conversion mechanisms are discussed. Spectroscopic measurements show that long-duration excitation radiation reduces ultraviolet up-conversion luminescence intensity, and this intensity reduction is related to sample heating due to high excitation radiation density and a poor heat sink from samples. It was found that sample configuration for spectroscopic measurements is crucial to correctly describe measured up-conversion luminescence spectra.
Using an Integrated Model of Strain and Routine Activities to Explore the Reciprocal Relationship Between Direct/Various Victimization and Criminal Coping Among Serious Adolescent Offenders
Authors: Park Yeoju , Metcalfe Christi
Published: September 2021

Using an integrated model of general strain and lifestyle/routine activities theories, the study aimed to prospectively assess the reciprocal relationship between direct victimization, vicarious victimization, and delinquency/crime over time among serious offenders. A cross-lagged path model was conducted using three waves from the Pathways to Desistance Study. Past victimization consistently predicted future victimization, while past delinquency/crime consistently affected future delinquency/crime, demonstrating stability across these variables. Prior vicarious victimization also indirectly increased subsequent direct victimization and delinquency/crime. However, there were no direct or indirect effects found between direction victimization and later vicarious victimization or delinquency/crime, or between delinquency/crime and later direct or vicarious victimization. Sensitivity analyses revealed the contemporaneous effects of victimization were more consequential on offending than the lagged effects.
Undergraduate Researcher Stories: Insights for Mentoring in an Open and Distance Learning Context
Authors: De Silva Radhika , Devendra Dinali
Published: September 2021

Research is a requisite for most of the undergraduate honors degrees offered by universities worldwide and these undergraduates are expected to submit a dissertation based on their research. Given the new demands of this independent component of learning, it is important to understand the challenges faced by students and the strategies that they employ in successfully navigating the various components of this process. This knowledge is useful to mentors and course developers as it provides insights about the firsthand experience of the students. The present study used a qualitative research design to investigate the research experience of a purposive sample of undergraduates who completed their Bachelor of Arts Honors in English and English Language Teaching in an open and distance university in Sri Lanka in the academic year 2017/2018. The responses from 12 undergraduates in the form of written stories were coded and analyzed thematically. The study revealed areas which need attention by mentors, faculty, and universities, especially those in open and distance contexts, when providing support to novice researchers.
Embodying Daoist Internal Arts: Walking the Line between the Reification and the Instrumental Use of Cognition
Authors: Giovine Vittorio
Published: September 2021

Existing research into the body pedagogics of cultural practices emphasises tacit/pre-reflective/corporeal knowledge, yet the role of cognition requires further non-dualist/non-conflationist theoretical elaboration. This article contributes to this task through an ethnographic case study of Daoist Internal Arts (DIA) – eastern self-cultivation practices including neigong, qigong and tai chi. Daoist Internal Arts practitioners employ cognitive thought to facilitate a phenomenological shift from a Cartesian/dualist to a non-dualist mode of embodiment whereby mind and body are experienced in their ontological unity. Yet the effective use of thought in this process requires practitioners to walk a fine line between reifying cognition as a substance separate from corporeality, thus opposing mind and body, and utilising it as an instrument to address corporeality and foster mind–body unity. In underscoring this ambivalent character of cognition, I outline a sociological perspective of embodiment that avoids both dualist and conflationist accounts of cognitive and corporeal dimensions.

Published: September 2021

Service-learning provides an experientially-based pedagogical approach that can increase student engagement in the learning environment and promote the development of cultural competency when working with diverse populations. This article reports on the curriculum development of a Latinx mental health undergraduate service-learning course that discussed disparities in Latinx access and utilization of mental health services and used service-learning as a teaching method to increase students’ cultural awareness and skills by putting their knowledge into practice in community-based settings. We provide an overview of the course including specific guidelines for readings, assignments, and group facilitation for future application of this course in Latinx mental health. Students of this course have developed critical awareness of their identities as it relates to their work with Latinxs, and a continued commitment to meet community needs. We briefly discuss challenges in implementing similar ethnically-rooted and service-learning multicultural psychology curriculum.

Effect of anterior overbite malocclusion on smile esthetics in adult patients
Authors: Cheng Johnson Hsin-Chung , Lee Tracy Yi-Hsuan , Cheng Pei-Chin , Chen Daniel De-Shing
Published: September 2021

Objective

To investigate whether overbite affects smile esthetics.

Methods

This study involved 106 patients with complete pretreatment records. Lateral cephalometric tracings were used to measure hard tissue variables. Frontal smile and upper occlusal photographs were used to measure nine smile esthetic variables: arc ratio, number of teeth, upper incisor exposure, upper midline, buccal corridor ratio, smile index, archform index, lower teeth exposure, and interlabial gap. The patients were classified into three groups according to their overbites (B1: 0–4 mm, B2: >4 mm, and B3: <0 mm). Analysis of variance was performed to compare 14 cephalometric measurements and the 9 smile esthetic variables. Multiple linear regression analysis was performed to determine the influencing cephalometric factors.

Results

Only upper incisor exposure was significantly different among the groups. In the multiple linear regression analysis, upper incisor exposure was positively associated with the distance from the upper incisor to the palatal plane in Group B2. No significant correlations were observed between cephalometric measurements and smile variables in Groups B1 and B3.

Conclusions

Smile variables were not significantly different among patients with various overbite malocclusions with the exception of upper incisor exposure. Overbite malocclusions do not appear to influence smile esthetics in adult patients.
DICER-AS1 functions as competing endogenous RNA that targets CSR1 by sponging microRNA-650 and suppresses gastric cancer progression
Authors: An Junyan , Guo Xiaoling , Yan Bingli
Published: September 2021

Objective

This study explored the functional interactions between the long non-coding RNA DICER-AS1 and the cellular stress response 1 ( CSR1) gene in gastric cancer.

Methods

Quantitative polymerase chain reaction (qPCR) and western blotting were used to measure DICER-AS1, CSR1, and miR-650 expression levels. Gastric cancer cell line proliferation and migration abilities were analyzed using the MTT and transwell migration and invasion assays, respectively. Bioinformatic analysis and dual luciferase reporter assays were employed to study the functional interactions among miR-650, DICER-AS1, and CSR1.

Results

DICER-AS1 and CSR1 expression levels were significantly decreased in gastric cancer tissues compared with normal tissues, and qPCR analysis showed that miR-650 was upregulated in gastric cancer tissues. Bioinformatic analysis and dual luciferase reporter assays revealed that DICER-AS1 functioned as a competing endogenous RNA that sponged miR-650, which in turn regulated CSR1 expression. Importantly, ectopic DICER-AS1 and CSR1 expression inhibited cell proliferation and migration in vitro and suppressed xenograft tumorgenicity in vivo.

Conclusions

These results suggest that DICER-AS1 functions as a competing endogenous RNA that regulates miR-650 to suppress proliferation and migration of gastric cancer cells by targeting CSR1. These findings indicate that targeting DICER-AS1 and miR-650 could be a novel treatment for gastric cancer.
Delayed-onset malignant hyperthermia in the postanesthetic care unit: a case report
Authors: Min Ji Young , Hong Sang Hyun , Kim Sung Jun , Chung Mee Young
Published: September 2021

Malignant hyperthermia (MH) is a potentially fatal hypermetabolic syndrome that occurs when susceptible individuals are exposed to triggering agents. Variability in the order and time of occurrence of symptoms often makes clinical diagnosis difficult. A late diagnosis or misdiagnosis of delayed-onset MH may lead to fatal complications. We herein report a case of delayed-onset MH in the postoperative recovery room. A 77-year-old man awoke from anesthesia and was transferred to the recovery room. Ten minutes after his arrival, his mental status became stuporous and he developed masseter muscle rigidity, hyperventilation, and a body temperature of 39.8°C. The patient was suspected to have MH, and 60 mg of dantrolene sodium (1 mg/kg) was administered via intravenous drip with symptomatic treatment. Within 10 minutes of dantrolene administration, the patient’s clinical signs subsided. This case report demonstrates that rapid diagnosis and treatment are crucial to ensure a good prognosis for patients with MH. A high level of suspicion based on clinical symptoms and early administration of therapeutic drugs such as dantrolene will also improve the clinical course. Therefore, suspicion and prompt diagnosis are absolutely essential. This case report emphasizes the importance of continuous education in the diagnosis and treatment of MH.

Published: September 2021

Odontogenic carcinosarcoma is a very rare malignant odontogenic tumor, characterized by malignant epithelial and mesenchymal components. Studies have reported several cases of odontogenic carcinosarcoma, mainly in the upper and lower jaws, with malignant clinical manifestations. Herein, we present the case of a 58-year-old woman with odontogenic carcinosarcoma with dentinoid in the left maxilla. The invasion range was large, and the left maxillary molar was missing. Histology revealed odontogenic carcinosarcoma with bidirectional differentiation characteristics and comprising three components: malignant epithelium, malignant interstitium, and dentinoid. The patient subsequently underwent nasal endoscopic sinus tumor resection, and she recovered well after surgery. After a strict 4-year follow-up, to date, there are still no signs of disease or local recurrence. To our knowledge, this is the first reported case of odontogenic carcinosarcoma with dentinoid. Our study describes the clinical, morphological, and immunohistochemical characteristics of this case, and distinguishes it from related diseases.
Extratesticular gliomatosis peritonei after mesenteric teratoma: a case report and literature review
Authors: Li Jiaqiang , Li Shoulin , Xiao Dong , Song Jiaming , Mao Jianxiong , Yin Jianchun
Published: September 2021

Mesenteric teratoma is a rare extragonadal teratoma. Gliomatosis peritonei (GP) is mature glial tissue implanted into the peritoneum's surface and is mainly accompanied by ovarian teratoma. Only a few cases of gliomatosis have occurred in the extraperitoneum. We present a rare case of a 3-year-old boy who presented with extratesticular GP after excision of an immature mesenteric teratoma at 2 months old. After the extratesticular mass was excised, we found ductile tissue on the surface of the terminal spermatic cord and epididymis. Some ductile tissue of the epididymis was removed and sent to a laboratory for a pathological examination. The mass and the ductile tissue of the epididymis had a hard consistency. The pathological diagnosis was extratesticular gliomatosis. Complete surgical resection of the teratoma and GP is helpful for identifying the presence of malignant lesions and for preventing malignant transformation. However, characteristics of GP lesions are extensive and they are difficult to completely remove. Moreover, GP is usually benign. Therefore, the residual GP tissue was not completely removed in our case. The child is still in good health, but requires lifelong follow-up. In conclusion, we report our experience of a rare case of extraperitoneal GP from an extragonadal teratoma.
Nerve injury following ultrasound-guided nerve root block with 2% lidocaine for shoulder manipulation: a case report
Authors: Kwak Soyoung , Chang Min Cheol
Published: September 2021

Shoulder manipulation under ultrasound (US)-guided C5 and C6 nerve root block is effective for treating refractory adhesive capsulitis (AC). We herein report the development of cervical nerve root injury following manipulation under anesthesia (MUA) in a patient with AC. A 47-year-old woman underwent shoulder manipulation under US-guided C5 and C6 root block with 2% lidocaine for the management of AC-induced shoulder pain. For the procedure, 3 mL of 2% lidocaine (total of 6 mL) was injected around each C5 and C6 nerve root under US guidance. Seven days after the procedure, the patient visited a university hospital because of severe neuropathic pain (numeric rating scale score of 9) in the right anterior arm, lateral arm, and forearm areas. Sensory deficits in the corresponding C5 and C6 dermatomes and motor weakness of the right shoulder abductor, elbow flexor, and wrist extensor were observed. Electrophysiologic studies demonstrated C5 and C6 nerve root injury. The patient was diagnosed with right C5 and C6 nerve root injury following MUA, and lidocaine toxicity or ischemia was the suspected cause. Clinicians should be mindful of the possibility of this complication.

Published: September 2021

Introduction:

Osimertinib is a third-generation epidermal growth factor receptor (EGFR) tyrosine kinase inhibitor (TKI) approved as first-line therapy for advanced EGFR-mutated non-small cell lung cancer (NSCLC). Some osimertinib-related interstitial lung diseases (ILDs) were shown to be transient, called transient asymptomatic pulmonary opacities (TAPO)—clinically benign pulmonary opacities that resolve despite continued osimertinib treatment—and are not associated with the clinical manifestations of typical TKI-associated ILDs.

Methods:

In this multicentric study, we retrospectively analyzed 92 patients with EGFR-mutated NSCLC treated with osimertinib. Computed tomography (CT) examinations were reviewed by two radiologists and TAPO were classified according to radiologic pattern. We also analyzed associations between TAPO and patients’ clinical variables and compared clinical outcomes (time to treatment failure and overall survival) for TAPO-positive and TAPO-negative groups.

Results:

TAPO were found in 18/92 patients (19.6%), with a median follow-up of 114 weeks. Median onset time was 16 weeks (range 6–80) and median duration time 14 weeks (range 8–37). The most common radiologic pattern was focal ground-glass opacity (54.5%). We did not find any individual clinical variable significantly associated with the onset of TAPO or significant difference in clinical outcomes between TAPO-positive and TAPO-negative groups.

Conclusions:

TAPO are benign pulmonary findings observed in patients treated with osimertinib. TAPO variability in terms of CT features can hinder the differential diagnosis with either osimertinib-related mild ILD or tumor progression. However, because TAPO are asymptomatic, it could be reasonable to continue therapy and verify the resolution of the CT findings at follow-up in selected cases.
Effect of cutting edge geometry change due to tool wear on hole quality in drilling of carbon fiber reinforced plastics using advanced ceramic coated tools
Authors: Bin Abdullah Mohammad Sayem , Kim Dave , Kwon Patrick , Kim Tae-Gon
Published: September 2021

This paper aims to study the evolution of cutting edge geometry due to tool wear and discuss its impact on the hole quality of a carbon fiber reinforced plastic (CFRP) laminate. A drilling experiment was conducted using three types of twist drills: uncoated, BAM (AlMgB14) coated, and (AlCrSi/Ti)N nanocomposite coated tungsten carbide tools. After generating 120 holes, the uncoated drill had the largest cutting edge radius (∼36 µm), while the BAM coated drill had the most extensive flank wear (∼287 µm) among the three drills. This relatively rapid tool wear results in a reduction of average hole size and a considerable variation on the hole profiles. The worn drills with the cutting edge radius greater than 19.3 µm form the fiber pull-outs in not only the 135° plies but also the adjacent 45° and 90° plies from the cutting direction, creating deep void networks. This type of networked fiber pull-out damage was observed with the holes machined by the uncoated and BAM coated drills. The (AlCrSi/Ti)N coated drill, which experienced the least amount of flank wear and the least increase of cutting edge radius, generated consistently sized holes up to 120 holes. However, the relatively sharp (AlCrSi/Ti)N coated tool results in the higher arithmetic roughness average (Ra) and the maximum roughness height (Rz) values than the other tools due to the localized fiber pull-outs and the absence of severe matrix smearing.
CLPTM1L Is a Novel Putative Oncogene Promoting Tumorigenesis in Oral Squamous Cell Carcinoma
Authors: Hou Yunwen , Xue Feifei , Fu Yu , Feng Guanying , Wang Ruixia , Yuan Hua
Published: September 2021

This study aimed to explore the function of CLPTM1L in oral squamous cell carcinoma and mechanism of tumorigenesis. The expression of CLPTM1L was detected by immunohistochemistry. The localization in cells was detected by immunofluorescence. Cell invasion, proliferation, and migration were detected by transwell, CCK-8 and scratch-wound test. The possible characteristics of CLPTM1L were analysed in TCGA, GO, KEGG and String databases. IHC revealed that the expression of CLPTM1L in 92 cases of OSCC tissues was significantly higher ( P < 0.01) than 29 cases of normal oral epithelium tissues. The expression of CLPTM1L was significantly higher in oral squamous cell carcinoma in TCGA database. CLPTM1L expression was not significantly correlated with the patients’ clinical parameters. High expression of CLPTM1L was associated with worse prognosis. Cox regression analysis demonstrated that the CLPTM1L expression was the significant risk factor. CLPTM1L was mainly localized in the perinuclear cytoplasm. The vitro studies revealed that the knockdown of CLPTM1L suppressed invasion, proliferation and migration. CLPTM1L related genes were enriched in protein processing in the endoplasmic reticulum, protein folding, endoplasmic reticulum formation, N-glycan biosynthesis, and protein hydroxylation. Highly expressed CLPTM1L may contribute to a poor prognosis and increase invasion, proliferation and migration of oral squamous cell carcinoma. CLPTM1L may play an important role in tumorgenesis and would be a valuable target gene for the treatment of oral squamous cell carcinoma.
Unprofessional conduct by nurses: A document analysis of disciplinary decisions

Published: September 2021

Background:

A small minority of nurses are investigated when they fail to meet the required professional standards. Unprofessional conduct does not just affect the nurse but also patients, colleagues and managers. However, it has not been clearly defined.

Objective:

The objective was to identify unprofessional conduct by registered nurses by examining disciplinary decisions by a national regulator.

Design:

A retrospective document analysis.

Data and research context:

Disciplinary decisions delivered to 204 registered nurses by the Finnish national regulatory authority from 2007 to 2016. The data were analysed with quantitative statistics.

Ethical consideration:

The study received permission from the Finnish National Supervisory Authority for Welfare and Health and used confidential documents that were supplied on the basis of complete anonymity and confidentiality.

Findings:

The mean age of the registered nurses who were disciplined was 44 years and 81% were female. Two-thirds had worked for their employer for 5 years or less, 53% had two or more employers and 18% had a criminal history. All the decisions included a primary reason for why the nurses were investigated, but there were also 479 coexisting reasons. In most cases, unprofessional conduct was connected to substance abuse (96%). In addition, stealing of medicine, a decreased ability to work and neglect of nursing guidelines were reported.

Discussion:

We found that the nurses were investigated for unprofessional conduct for complex combinations of primary and coexisting reasons. Our study highlighted that more attention needs to be paid to the key markers for unprofessional conduct.

Conclusion:

Unprofessional conduct is a complex phenomenon that is connected to nurses’ individual and working backgrounds and has an impact on their work performance. More research is needed to identify how nursing communities can detect, manage and limit the serious effects and consequences of unprofessional conduct.
Pre-decision regret before transition of dependents with severe dementia to long-term care
Authors: Hanssen Ingrid , Mkhonto Flora M , Øieren Hilde , Sengane Malmsey LM , Sørensen Anne Lene , Tran Phuong Thai Minh
Published: September 2021

Background:

To place a dependent with severe dementia in a nursing home is a painful and difficult decision to make. In collectivistic oriented societies or families, children tend to be socialised to care for ageing parents and to experience guilt and shame if they violate this principle. Leaving the care to professional caregivers does not conform with the cultural expectations of many ethnic groups and becomes a sign of the family’s moral failure.

Research design:

Qualitative design with individual in-depth interviews with nurses, family members and dementia care coordinators in Norway, Montenegro, Serbia and South Africa. Braun and Clarke’s six analytic phases were used.

Ethical considerations:

The project was approved by the Regional Committee for Research, South-Eastern Norway; the Norwegian Centre for Research Data; the Ethics Committee; University of Limpopo, MEDUNSA Campus, South Africa; and by the local heads of the respective nursing homes or home care services. Interviewees were informed orally and in writing and signed an informed consent form.

Findings:

Healthcare professionals tend to be contacted only when the situation becomes unmanageable. Interviewees talked about feelings of obligation, shame and stigma in their societies regarding dementia, particularly in connection with institutionalisation of family members. Many lacked support during the decision-making process and were in a squeeze between their own needs and the patients’ need of professional care, and the feeling of duty and worry about being stigmatised by their surroundings. This conflict may be a source of pre-decision regret.

Conclusion:

Family caregivers need help to understand the behaviours of persons with dementia and how to access the formal and informal services available. Thus, they may provide effective support to patients and family carers alike. Supportive interventions for caregivers need to be tailored to meet the individual needs of both the caregiver and the persons with dementia.
The Moderating Effect of Attachment Styles on the Relationship Between Celebrity Credibility and Brand Attachment
Authors: Namrata  , Parmar Yadvinder
Published: September 2021

The current study aims to address the triadic relationship among the celebrity endorser, consumer and brand. The objective of this study is to investigate the influence of moderating role of attachment style dimensions on the relationship between the celebrity endorser traits and brand attachment. This study applies associative network theory and attachment theory to build the theoretical framework of the study. Data were gathered using a sample of 484 respondents. AMOS was used to employ structural equation modelling to test the hypotheses of the study. The results of the study reveal that celebrity expertise and trustworthiness are likely to enhance consumer brand attachment, whereas celebrity attractiveness does not lead to building brand attachment. It also discloses that both the dimensions of attachment style, namely anxiety and avoidance, have a moderating impact on the relationship between celebrity endorser traits and brand attachment. This study provides multiple implications for the marketing practitioners and academicians.
Competition and Banking Industry Stability: How Do BRICS and G7 Compare?
Authors: Oredegbe Abayomi
Published: September 2021

This study examines banking industry stability in BRICS and G7 from the period 2005 to 2014. The results show that stability level in a prior period affects stability in the subsequent period. Also, the study reveals that competition improves stability, which validates the competition-stability proposition. Economic growth enhances stability in BRICS but not in G7. Inefficiency weakens stability in BRICS; however, its impact in G7 is insignificant. Profitability, capitalization, and inflation enhance stability in G7; however, they show no meaningful impacts in BRICS. These findings contribute to literature and policy discussion on banking industry stability

An Innovative Three-in-One Face Protective Gear (FPG): A Feasibility Study in a Neonatal Unit in Times of Pandemic!
Authors: Panghal Astha , Gupta Ashok Kumar , Gupta Girish , Naranje Kirti M. , Singh Anita
Published: September 2021

Background:

Healthcare workers (HCWs) are at greatest risk of acquiring infection in times of global pandemic of COVID-19 disease. There is an unprecedented demand of several forms of personal protective equipment (PPE) for HCWs leading to possible acute shortage of these equipment. This has paved way for development of local innovative PPEs.

Objective:

To test feasibility of a low cost, indigenous three-in-one face protective gear (FPG) in HCWs of a neonatal unit of a tertiary care institute in northern India.

Methodology:

A three-in-one FPG was developed using the commonly available items in a ward or intensive care and few trash items. Items used were sterile surgical sheet, cling wrap piece/transparency sheet, cover of umbilical catheter/any sterile hollow plastic pipe, or straw and adhesive tape. The FPG was tested in 17 HCWs regarding its ease to use, comfort, and feasibility with the help of questionnaire.

Results:

A total of 17 HCWs participated in this study. Majority (10, 58.8%) were doctors. Eight (47%) participants have never used any form of PPE previously. Thirteen (76.4%) participants found the FPG comfortable to wear; 12 (70.5%) found it comfortable to wear up to 8 h. Three HCWs found it difficult to work when wear the FPG; 1 out of 3 found it suffocating.

Conclusion:

Three-in-one FPG is an indigenous, low cost, and may be a feasible alternative in low-risk situations when there is scarcity of conventional protective equipment.
Connecting the Disconnected: The Role of ICT in Women’s Livelihood Restoration in the Resettlement Site Kannagi Nagar in Chennai, India
Authors: Almira Atika , Eerd Maartje van
Published: September 2021

In Chennai, Development-Induced Displacement and Resettlement (DIDR) pushes the urban poor to resettlement sites in the outskirts of the city. One of those sites is Kannagi Nagar, located 15 km from the city centre, in which women suffer from more significant livelihood deprivation. As there is evidence of Information and Communication Technology (ICT) being useful in development, this study aims to explain the role of ICT in the livelihood restoration and enhancement of the social and financial capital for women in Kannagi Nagar. Through a case study with a blend of quantitative and qualitative techniques, the research incorporated a closed-ended questionnaire survey and interviews. Among the women, ICT use is prevalent, however, they have not fully optimized the potentials of ICT for livelihood restoration. The use is still limited to the purpose of maintaining the contacts they already have. However, some women have been able to use ICT, especially through their phones, for the restoration and enhancement of their social and financial capital. Nonetheless, to harness the full potential of ICT and strengthen women’s agency, access to ICT should be improved.

Recent research has increasingly documented the adverse effects of ADHD on physical health in addition to its well-known effects on emotional health. Responding to this concern, CHADD organized a summit meeting of health care providers, governmental and other health-related organizations, and health care payers. A White Paper generated from the meeting reviewed the adverse health outcomes, economic burden and public health implications of unmanaged ADHD. Here we summarize the resulting Calls to Action to the various stakeholder groups including: increased awareness and education of providers; development of professional guidelines for diagnosis and treatment; insurance coverage of the relevant services; support of research targeting the role of ADHD in the etiology and treatment of physical illness; and public education campaigns.
