Unraveling the mysteries of Goeldia Keyserling, 1891: revision, description of seven new species and first record from USA (Araneae: Titanoecidae)
Authors: ALMEIDA-SILVA LINA M. , BRESCOVIT ANTONIO D.
Published: March 2024

The spider genus Goeldia Keyserling is revised, seven new species are described, two species are revalidated and new synonyms are proposed. Goeldia patellaris (Simon, 1892) is removed from the synonymy with Goeldia obscura Keyserling, 1891 and considered a senior synonym of G. arnozoi (Mello-Leitão, 1924). This resulted in a secondary homonymy with Goeldia obscura Keyserling, 1878, which was resolved with the proposal of G. leechi Almeida-Silva & Brescovit nomen novum for the type species (Goeldia obscura Keyserling, 1891). Goeldia funesta (Keyserling, 1883) is removed from the synonymy with G. obscura (Keyserling, 1878) and revalidated. Goeldia munda (Chamberling, 1916) is removed from the synonym with Goeldia patellaris (Simon, 1892) and placed as synonym of G. funesta. Calleva paupercula Simon, 1892 is removed from the synonym with Goeldia patellaris (Simon, 1892) and placed as junior synonym of G. luteipes (Keyserling, 1891). Newly described species are: G. bagumbubu sp. nov., Goeldia diva sp. nov., G. gauderio sp. nov., G. goytacazes sp. nov., and G. mirim sp. nov., all from Brazil, G. portenha sp. nov. from Argentina and G. utcuyacu sp. nov. from Peru. Here we also include the first descriptions of the male of Goeldia obscura (Keyserling, 1878), G. funesta (Keyserling, 1883), and G. nigra (Mello-Leitão, 1917) and first description of the female G. guayaquilensis (Schmidt, 1971). Detailed examination of Goeldia tizamina (Chamberlin & Ivie, 1938) types shows that they are adult specimens, but not congeneric with species of Goeldia and will be treated in another publication. Other discoveries include the placement of Amaurobius thoracicus Mello-Leitão, 1945 as junior synonym of Goeldia luteipes (Keyserling, 1891), first record of Goeldia funesta to USA and new distribution records for several species.

Authors: MONTALVO-SALAZAR JORGE L. , LÓPEZ-GARCÍA MARGARITA M.
Published: March 2024

Ennya is a very speciose genus of treehoppers, especially in the northern Andes. After review of the type material of most species of the genus, the following nomenclatural changes are proposed: Ennya nebulosa Breddin syn. nov. of Ennya chlorizans Breddin stat. rev., Ennya gibbera Goding reinst. comb., Ennya funkhouseri Goding stat. rev., Creonus fasciata Fallou comb. nov., Centronodus gounellei Fallou comb. nov., and, as Polyglyptini incertae sedis, Maturna rufomaculata Fallou. Lectotypes are designated for E. ecuadorensis Fowler, E. conspersa Stål, E. notata Stål, and E. nutans Stål. Two new species are described from the Ecuadorian Andes: Ennya allkukiru Montalvo-Salazar sp. nov. and E. lamariela Montalvo-Salazar & López-García sp. nov. The first immature of the genus is described. Lastly, we provide a key to all Ennya species and new distributional records within Ecuador of E. chrysura Fairmaire, E. sobria Walker, and E. scaramozzinoi Creão-Duarte & Sakakibara.

Published: March 2024

Background

Body weight and size are important economic traits in chickens. While many growth-related quantitative trait loci (QTLs) and candidate genes have been identified, further research is needed to confirm and characterize these findings. In this study, we investigate genetic and genomic markers associated with chicken body weight and size. This study provides new insights into potential markers for genomic selection and breeding strategies to improve meat production in chickens.

Methods

We performed whole-genome resequencing of and Wenshang Barred (WB) chickens (n = 596) and three additional breeds with varying body sizes (Recessive White (RW), WB, and Luxi Mini (LM) chickens; (n = 50)). We then used selective sweeps of mutations coupled with genome-wide association study (GWAS) to identify genomic markers associated with body weight and size.

Results

We identified over 9.4 million high-quality single nucleotide polymorphisms (SNPs) among three chicken breeds/lines. Among these breeds, 287 protein-coding genes exhibited positive selection in the RW and WB populations, while 241 protein-coding genes showed positive selection in the LM and WB populations. Genomic heritability estimates were calculated for 26 body weight and size traits, including body weight, chest breadth, chest depth, thoracic horn, body oblique length, keel length, pelvic width, shank length, and shank circumference in the WB breed. The estimates ranged from 0.04 to 0.67. Our analysis also identified a total of 2,522 genome-wide significant SNPs, with 2,474 SNPs clustered around two genomic regions. The first region, located on chromosome 4 (7.41-7.64 Mb), was linked to body weight after ten weeks and body size traits. LCORL, LDB2, and PPARGC1A were identified as candidate genes in this region. The other region, located on chromosome 1 (170.46-171.53 Mb), was associated with body weight from four to eighteen weeks and body size traits. This region contained CAB39L and WDFY2 as candidate genes. Notably, LCORL, LDB2, and PPARGC1A showed highly selective signatures among the three breeds of chicken with varying body sizes.

Conclusion

Overall this study provides a comprehensive map of genomic variants associated with body weight and size in chickens. We propose two genomic regions, one on chromosome 1 and the other on chromosome 4, that could helpful for developing genome selection breeding strategies to enhance meat yield in chickens.

Published: March 2024

Background

Quinoa leaves demonstrate a diverse array of colors, offering a potential enhancement to landscape aesthetics and the development of leisure-oriented sightseeing agriculture in semi-arid regions. This study utilized integrated transcriptomic and metabolomic analyses to investigate the mechanisms underlying anthocyanin synthesis in both emerald green and pink quinoa leaves.

Results

Integrated transcriptomic and metabolomic analyses indicated that both flavonoid biosynthesis pathway (ko00941) and anthocyanin biosynthesis pathway (ko00942) were significantly associated with anthocyanin biosynthesis. Differentially expressed genes (DEGs) and differentially accumulated metabolites (DAMs) were analyzed between the two germplasms during different developmental periods. Ten DEGs were verified using qRT-PCR, and the results were consistent with those of the transcriptomic sequencing. The elevated expression of phenylalanine ammonia-lyase (PAL), chalcone synthase (CHS), 4-coumarate CoA ligase (4CL) and Hydroxycinnamoyltransferase (HCT), as well as the reduced expression of flavanone 3-hydroxylase (F3H) and Flavonol synthase (FLS), likely cause pink leaf formation. In addition, bHLH14, WRKY46, and TGA indirectly affected the activities of CHS and 4CL, collectively regulating the levels of cyanidin 3-O-(3’’, 6’’-O-dimalonyl) glucoside and naringenin. The diminished expression of PAL, 4CL, and HCT decreased the formation of cyanidin-3-O-(6”-O-malonyl-2”-O-glucuronyl) glucoside, leading to the emergence of emerald green leaves. Moreover, the lowered expression of TGA and WRKY46 indirectly regulated 4CL activity, serving as another important factor in maintaining the emerald green hue in leaves N1, N2, and N3.

Conclusion

These findings establish a foundation for elucidating the molecular regulatory mechanisms governing anthocyanin biosynthesis in quinoa leaves, and also provide some theoretical basis for the development of leisure and sightseeing agriculture.

Published: March 2024

Introduction

In Mongolia, there has been limited research on the posttreatment survival rate, recurrence, and occurrence of oral cancer. The goal of this study is to investigate the risk factors that contribute to the recurrence of oral cancer to increase survival rates, facilitate early detection, and improve treatment accuracy.

Method

A retrospective cohort method was used, with medical records from 173 patients diagnosed with squamous cell carcinoma of the mouth at the National Cancer Center of Mongolia’s Department of Head and Neck Surgery, Radio, and Chemotherapy between 2012 and 2017. The Mongolian National University of Medical Sciences’ Research Ethics Committee approved the project.

Results

The findings revealed that 109 cases (63.0%) were men and 64 (37.0%) were females, with a large proportion of patients (28.3%) falling between the ages of 61 and 70. Men had a 3.8 times higher risk of cancer recurrence than women (OR = 3.79, CI = 1.24–11.57). Furthermore, lymph node metastases and treatment were linked to oral cancer recurrence.

Conclusion

This study offers light on the factors that influence the recurrence of oral cancer, giving useful insights for improving patient outcomes through early detection and proper treatment.

Authors: Yuan Jia-jia , Zhao Ya-nan , Lan Xing-yu , Zhang Yong , Zhang Rong
Published: March 2024

Background

Autism spectrum disorder (ASD) is heritable neurodevelopmental disorders (NDDs), but environmental risk factors have also been suggested to a play a role in its development. Prenatal, perinatal and parental factors have been associated with an increased risk of ASD in children. The aim of the present study was to explore the prenatal, perinatal, and parenting risk factors in children with autism spectrum disorder (ASD) from Beijing, China by comparing them with typically developing (TD) children.

Methods

A sample of 151 ASD children’s parents who from rehabilitation institutions in Beijing were enrolled in this study, and an additional 151 children from kindergartens in Beijing were recruited as a control group (child age: mean = 4.4 years). TD children were matched according to age, sex and maternal education. We explored the maternal AQ (Autism Spectrum Quotient) scores (mean:19.40-19.71, no significant difference between two groups) to referring the genetic baseline. This study evaluated 17 factors with unadjusted and adjusted analyses.

Results

Birth asphyxia was associated with a more than a thirteen-fold higher risk of ASD (adjusted odds ratio (AOR) = 13.42). Breastfeeding difficulties were associated with a higher risk of ASD(AOR = 3.46). Parenting influenced the risk of ASD, with low responding (LR) and harsh or neglectful parenting associated with a higher risk of ASD in offspring (AOR = 2.37 for LR, AOR = 3.42 for harsh parenting and AOR = 3.01 for neglectful parenting). Maternal fever during pregnancy was associated with a higher risk of ASD in offspring (AOR = 3.81).

Conclusions

Many factors were associated with ASD in offspring. Further assessment is needed to elucidate the role of modifiable environmental factors to inform prevention strategies.

Published: March 2024

Background

Benzodiazepines are a class of medications that are being frequently prescribed in Canada but carry significant risk of harm. There has been increasing clinical interest on the potential “sparing effects” of medical cannabis as one strategy to reduce benzodiazepine use. The objective of this study as to examine the association of medical cannabis authorization with benzodiazepine usage between 2013 and 2021 in Alberta, Canada.

Methods

A propensity score matched cohort study with patients on regular benzodiazepine treatment authorized to use medical cannabis compared to controls who do not have authorization for medical cannabis. A total of 9690 medically authorized cannabis patients were matched to controls. To assess the effect of medical cannabis use on daily average diazepam equivalence (DDE), interrupted time series (ITS) analysis was used to assess the change in the trend of DDE in the 12 months before and 12 months after the authorization of medical cannabis.

Results

Over the follow-up period after medical cannabis authorization, there was no overall change in the DDE use in authorized medical cannabis patients compared to matched controls (− 0.08 DDE, 95% CI: − 0.41 to 0.24). Likewise, the sensitivity analysis showed that, among patients consuming ≤5 mg baseline DDE, there was no change immediately after medical cannabis authorization compared to controls (level change, − 0.04 DDE, 95% CI: − 0.12 to 0.03) per patient as well as in the month-to-month trend change (0.002 DDE, 95% CI: − 0.009 to 0.12) per patient was noted.

Conclusions

This short-term study found that medical cannabis authorization had minimal effects on benzodiazepine use. Our findings may contribute ongoing evidence for clinicians regarding the potential impact of medical cannabis to reduce benzodiazepine use.

Highlights

• Medical cannabis authorization had little to no effect on benzodiazepine usage among patients prescribed regular benzodiazepine treatment in Alberta, Canada.

• Further clinical research is needed to investigate the potential impact of medical cannabis as an alternative to benzodiazepine medication.
Welding fume exposure and prevalence of chronic respiratory symptoms among welders in micro- and small-scale enterprise in Akaki Kality sub-city, Addis Ababa, Ethiopia: a comparative cross-sectional study
Authors: Badima Hager , Kumie Abera , Meskele Bereket , Abaya Samson Wakuma
Published: March 2024

Background

Exposure to welding fumes can lead to different respiratory health disorders, including lung cancer, due to long-term exposures. In Ethiopia, large numbers of people are engaged in the welding sector. Often, these workers are exposed to welding fumes at their workplaces, however, the level of exposure and its health effects have never been studied.

Objective

To measure the level of personal welding fume exposure and assess chronic respiratory symptoms and associated factors, among micro and small-scale enterprise metal workshop workers, in Akaki Kality Sub city, Ethiopia.

Methods

A comparative cross-sectional study involving 226 welders and 217 controls. Chronic respiratory symptoms were assessed using a standardized questionnaire adopted from the American Thoracic Society (ATS). Welding fumes were collected from the welder’s breathing zone using 37 mm close-faced plastic cassettes fitted with Polyvinyl Chloride (PVC) filters connected to Casella pumps at an airflow rate of 2 L/min.

Result

The overall prevalence of chronic respiratory symptoms among welders and controls were 54 (23.9%) and 20 (9.2%) respectively. The geometric mean and geometric standard deviation (GSD) of personal welding fume exposure, among welders was 5.98 mg/m3 (± GSD = 1.54). In this study, 53.3% of the samples exceeded the Occupational Exposure Limit defined by the American Conference of Governmental Industrial Hygiene. Chronic respiratory symptoms were significantly associated with educational status (Adjusted Odds Ratio (AOR): 5.11, 95% CI: 1.35, 19.33), respiratory protective equipment use (AOR: 3.33, 95% CI: 1.52, 7.31), safety training (AOR: 2.41, 95% CI: 1.10, 5.28), smoking (AOR:3.57, 95% CI: 1.54, 8.23), welding machine maintenance (AOR: 1.87, 95% CI: 1.01, 3.59) and welding site (i.e. indoors vs. outdoor) (AOR: 6.85. 95% CI: 2.36, 19.89).

Conclusions

The prevalence of chronic respiratory symptoms among welding workers was significantly higher than controls. More than half of the samples exceeded the Occupational Exposure Limit. Educational status, implementation of safety training, and welding sites were significantly associated with chronic respiratory symptoms. The results suggested a need to reduce welding fume exposure to improve the respiratory health of the workers.
Cold EMR vs. Hot EMR for the removal of sessile serrated polyps larger than 10 mm: a systematic review and meta-analysis
Authors: Ding Cong , Yang Jian-feng , Wang Xia , Zhou Yi-feng , Khizar Hayat , Jin Zheng , Zhang Xiao-feng
Published: March 2024

Background

Endoscopic mucosal resection (EMR) appears to be a promising technique for the removal of sessile serrated polyps (SSPs) ≥ 10 mm. To assess the effectiveness and safety of EMR for removing SSPs ≥ 10 mm, we conducted this systematic review and meta-analysis.

Methods

We conducted a thorough search of Embase, PubMed, Cochrane, and Web of Science databases for relevant studies reporting on EMR of SSPs ≥ 10 mm, up until December 2023. Our primary endpoints of interest were rates of technical success, residual SSPs, and adverse events (AE).

Results

Our search identified 426 articles, of which 14 studies with 2262 SSPs were included for analysis. The rates of technical success, AEs, and residual SSPs were 100%, 2.0%, and 3.1%, respectively. Subgroup analysis showed that the technical success rates were the same for polyps 10–19 and 20 mm, and en-bloc and piecemeal resection. Residual SSPs rates were similar in en-bloc and piecemeal resection, but much lower in cold EMR (1.0% vs. 4.2%, P = 0.034). AEs rates were reduced in cold EMR compared to hot EMR (0% vs. 2.9%, P = 0.168), in polyps 10–19 mm compared to 20 mm (0% vs. 4.1%, P = 0.255), and in piecemeal resection compared to en-bloc (0% vs. 0.7%, P = 0.169).

Conclusions

EMR is an effective and safe technique for removing SSPs ≥ 10 mm. The therapeutic effect of cold EMR is superior to that of hot EMR, with a lower incidence of adverse effects.

The latissimus dorsi creates a dynamic track for the inferior angle of the scapula during arm abduction in humans
Authors: Paksoy Alp , Akgün Doruk , Gebauer Henry , Karczewski Daniel , Lacheta Lucca , Tokish John M. , Chamberlain Aaron , Moroder Philipp
Published: March 2024

Background

The importance of several scapulothoracic muscles, including trapezius and serratus anterior, in maintaining physiological scapula kinematics has been highlighted in the past. However, the relationship between the scapula and the latissimus dorsi muscle remains unclear. Our clinical surgical observation is that the latissimus dorsi does not directly attach but rather runs superficial to the inferior angle of the scapula. Based on this observation, we hypothesise that the latissimus dorsi creates a dynamic track on which the scapula glides under the muscle belly during elevation of the arm, creating the latissimus-scapula overlap (LSO).

Methods

All consecutive patients who had a whole-body computed tomography scan (CT) in case of polytrauma evaluation between 2018 and 2021, with complete depiction of the scapula and latissimus dorsi muscle, were analysed. 150 shoulders in 90 patients with arms up were matched according to their age (within five years), gender, and affected side with 150 shoulders in 88 patients with arms down. Patients with pathologies of the upper extremities or thorax that potentially could alter LSO measurements were excluded. LSO was calculated as a ratio of the measured area of the latissimus dorsi projection on the scapula and the total scapula area.

Results

The mean age of the 178 patients (48 females; 13 males) was 60 years. The arms-up group showed a significantly higher LSO than the arms-down group (19.9 ± 6.3% vs. 2.7 ± 2.2%; p < 0.0001). In the arms-up group, approximately one fifth of the scapula was overlapped inferiorly by the muscle belly of the latissimus dorsi, contrary to the almost non-existing LSO in the arms-down group.

Conclusion

With arms up, humans show a significantly higher LSO in comparison to arms down indicating that the latissimus dorsi indeed creates a dynamic track on which the scapula is forced to travel during abduction of the arm. This finding of increased LSO during the elevation of the arm warrants further consideration of the role of the latissimus dorsi in scapula kinematics and potentially scapular dyskinesis.

Inflammatory bowel disease is associated with an increase in the incidence of multiple sclerosis: a retrospective cohort study of 24,934 patients
Authors: Yaqubi Kaneschka , Kostev Karel , Klein Isabel , Schüssler Sofia , May Petra , Luedde Tom , Roderburg Christoph , Loosen Sven H.
Published: March 2024

Background

Recent data suggest a potential pathophysiological link between inflammatory bowel disease (IBD) and multiple sclerosis (MS), two immune-mediated diseases both of which can have a significant impact on patients' quality of life. In the present manuscript, we investigate the association between IBD and MS in a German cohort of general practice patients. These results may have important implications for the screening and management of patients with IBD, as well as for further research into the pathophysiological mechanisms underlying both disorders.

Methods

4,934 individuals with IBD (11,140 with Crohn’s disease (CD) and 13,794 with ulcerative colitis (UC)) as well as 24,934 propensity score matched individuals without IBD were identified from the Disease Analyzer database (IQVIA). A subsequent diagnosis of MS was analyzed as a function of IBD using Cox regression models.

Results

After 10 years of follow-up, 0.9% and 0.7% of CD and UC patients but only 0.5% and 0.3% of matched non-IBD pairs were diagnosed with MS, respectively (pCD = 0.002 and pUC < 0.001). Both CD (HR: 2.09; 95% CI 1.28–3.39) and UC (HR: 2.35; 95% CI 1.47–3.78) were significantly associated with a subsequent MS diagnosis. Subgroup analysis revealed that the association between both CD and UC and MS was more pronounced among male patients.

Conclusion

The results of our analysis suggest a notable association between IBD and a subsequent MS diagnosis. These findings warrant further pathophysiological investigation and may have clinical implications for the screening of IBD patients in the future.

Clinical trials frequently include multiple end points that mature at different times. The initial report, typically based on the primary end point, may be published when key planned co-primary or secondary analyses are not yet available. Clinical Trial Updates provide an opportunity to disseminate additional results from studies, published in JCO or elsewhere, for which the primary end point has already been reported.

We previously reported comparable 3-year regional relapse–free survival (RRFS) using elective upper-neck irradiation (UNI) in N0-1 nasopharyngeal carcinoma (NPC) compared with standard whole-neck irradiation (WNI). Here, we present the prespecified 5-year overall survival (OS), RRFS, late toxicity, and additional analyses. In this randomized trial, patients received UNI (n = 224) or WNI (n = 222) for an uninvolved neck. After a median follow-up of 74 months, the UNI and WNI groups had similar 5-year OS (95.9% v 93.1%, hazard ratio [HR], 0.63 [95% CI, 0.30 to 1.35]; P = .24) and RRFS (95.0% v 94.9%, HR, 0.96 [95% CI, 0.43 to 2.13]; P = .91) rates. The 5-year disease-free survivors in the UNI group had a lower frequency of hypothyroidism (34% v 48%; P = .004), neck tissue damage (29% v 46%; P < .001), dysphagia (14% v 27%; P = .002), and lower-neck common carotid artery stenosis (15% v 26%; P = .043). The UNI group had higher postradiotherapy circulating lymphocyte counts than the WNI group (median: 400 cells/μL v 335 cells/μL, P = .007). In conclusion, these updated data confirmed that UNI of the uninvolved neck is a standard of care in N0-1 NPC, providing outstanding efficacy and reduced long-term toxicity, and might retain more immune function.

Published: March 2024

Abstract. The growing awareness of Halal compliance in today’s community shows the importance of Halal on the quality of products manufactured worldwide. Hence, it is crucial to ensure that the concept of Halal extends to the entire supply chain, from the farm to the consumer. Most research covers manufacturing and procurement, leaving Halal-compliant distribution and logistics open to a number of research opportunities. We conduct an investigation into digital Halal logistics from the perspective of the individual food delivery riders, focusing on the operational level of the supply chain. The extensive reliance on Internet-enabled smart phones and the growing popularity of food delivery have created an increasing number of job opportunities for delivery riders, mainly on motorcycles. However, there is a question around whether or not this delivery process is Halal compliant, given that the riders face many challenges in ensuring an acceptable quality of service. This study investigates how the riders perceive Halal compliance in the food delivery industry, and provides suggestions for the implementation of digital Halal at various operational checkpoints. Keywords: Digital logistics, Halal logistics, supply chain management, delivery riders.

Published: March 2024

Abstract. Cooperation between R & D institutions/universities and industry has been carried out a lot. Most of these partnerships have not produced a significant economic impact, as part of fostering national innovation. What is the cause of the unsuccessful cooperation? There are various studies on these failures, including those caused by: unclear reasons for cooperating, improper forms of cooperation, and not yet growing trust between them. This paper discusses research collaboration by paying attention to these three aspects. In addition, it is accompanied by policy implications to improve it. The research used qualitative descriptive analysis with data based on the results of a survey conducted by the Ministry of Research and Technology. The results of the analysis show that: (a) the reason there are still few industries that collaborate with R & D institutions and universities, is because the quality of technology produced by these institutions has not been proven; (a) the form of multi-stakeholder cooperation, involving other than industry and R&D institutions and universities, as well as other parties such as the government, is a form of good cooperation; (c) the industry trusts the performance of imported technology more than the domestic technology. The recommended policies include: (a) improving the quality of human resources, facilities, and infrastructure, as well as publishing research results from R & D institutions and universities in the media or forums, where industry is heavily involved; (b) the government acts as a regulator and facilitator in cooperation between industry and R&D institutions through various policy instruments; (c) technologies produced by R&D institutions and universities whose performance has been technically proven (TRL 6), need serious support.

Published: March 2024

Abstract. Cultural representations play an important role in tourism marketing. However, it is argued that the representation of Sundanese tradition and culture in the tourism marketing of Bandung is often overshadowed by the modern representation of the city. This paper explores the representation of Sundanese culture on the pictorial elements of the websites that promote Bandung tourism. This study used visual content analysis and semiotic analysis of the representations of Sundanese culture in Bandung promotional websites through pictorial data collections and coding of 83 websites and a total of 658 images. The results indicate that Sundanese traditional food dominates the representation of Sundanese culture in Bandung tourism marketing. Furthermore, this study suggests that Sundanese culture represents closeness to nature, harmony, warmth, egalitarianism, and togetherness. Implications to practice along with recommendations for future research are provided. Keywords: Cultural representation, visual content analysis, semiotic analysis, sundanese culture, pictorial destination image

Published: March 2024

Abstract. This research aims to determine whether there is a change in the amount of tip for drivers by customers during the COVID–19 pandemic compared to before the pandemic and to find out the customers' motives in tipping drivers during the COVID 19 pandemic. The research employs a quantitative approach through survey methods. The scale measurement technique uses the Likert scale and Interval scale. The number of respondents in this research are 453 Indonesian who use online motorcycle taxi service application. The data obtained were analyzed using SPSS through descriptive statistical analysis and multiple linear regression. The results show that most of the respondents tipped more amount during the COVID–19 pandemic than the amount of tip they gave before the pandemic. Giving a tip to drivers by customers was driven by several motives/reasons in the following order: a customer has the nature of wanting to help others without expecting to get rewards (altruism), wants to follow and obey applicable social norms (social norms), wants to give a reward for the satisfaction obtained from good service (reward positively), and wants to maintain social status and increase self–esteem in the social environment (social esteem).

Authors:   School of Business and Management Institut Teknologi Bandung, Putri Jessica Amanda , Sudrajad Oktofa Yudha , Kabir Rezaul ,   University of Twente, Netherlands
Published: March 2024

Abstract. This study compares ASEAN and EU banking efficiency using Data Envelopment Analysis (DEA) and an intermediary approach. Three input variables (staff expense, fixed assets, total customer deposits) and two output variables (loans to customer and operating income other than interest) are analyzed using RStudio and R. EU and ASEAN banks had efficiency scores of 0.7 and 0.65, respectively, showing opportunity for improvement. Based on cost analyses, ASEAN banks are more efficient than their EU counterparts. Inefficiencies occur when output surpasses input or is much lower than another output variable. However, both regions may improve banking efficiency to do better. The 10-year trends exhibit oscillations, showing that regulatory issues affect banking efficiency. Stricter laws, higher capital requirements, and risk management changes may have hampered ASEAN credit. The dynamics and objectives of the EU and ASEAN economic blocs shape their financial systems. ASEAN is working toward regulatory convergence, while the EU has integrated and harmonized more.

In order to improve the efficiency of biodiesel production from esterification of free fatty acids, an alternative to sulfuric acid has been explored in this study. These catalysts including three pyrrolidonium ionic liquids (ILs), 1-methyl-2-pyrrolidonium hydrogen sulfate ([Hnmp]HSO4), 2-pyrrolidonium hydrogen sulfate ([Hnhp]HSO4), and 1-(3-sulfonic acid) propyl-2-pyrrolidonium hydrogen sulfate ([C3SO3Hnhp]HSO4), were applied as catalysts to produce biodiesel through the esterification reaction of oleic acid with methanol. The catalytic performances of the synthesized ILs for the esterification of oleic acid were evaluated, and [C3SO3Hnhp]HSO4 exhibited the best catalytic activity among all tested acidic ILs. Moreover, the esterification of oleic acid with methanol by the [C3SO3Hnhp]HSO4-catalyzed was systematically explored, and the reaction conditions were further optimized through a single-factor experiment, the Plackett-Burman design, and a response surface methodology. It was found that optimum response for oleic acid conversion was 97.4% under reaction condition of using catalyst dosage of 12.5%, methanol/oleic acid molar ratio of 9:1, reaction time at 4 h and reaction temperature at 70 °C. In addition, the catalytic activity of [C3SO3Hnhp]HSO4 still remained high level after 5 cycles. In a conclusion, the IL [C3SO3Hnhp]HSO4 has great potential as a catalyst for producing fatty acid methyl esters via the esterification reaction.

INTRODUCTION. Today’s society needs personalities, both as educators and as learners, capable of rapid and flexible change in their lifestyle, and requires a rethinking of the educational paradigm, moving away from established adaptive-disciplinary models of learning in favour of scalable and personalised learning. The purpose of the study was to investigate the concept of “research culture” in relation to students of pedagogical specialities and to formulate basic requirements that contribute to the development of a research culture. METHOD. The methodological basis of the study lies in the general integrative philosophical-systemic approach, which is based on the provision on the universal connection of phenomena and the search for integral characteristics of the phenomena under study. RESULTS. During the study of the topic, the criteria and conditions for the formation of a research culture among future teachers-educators in higher education institutions were characterised. The study also resulted in the development of a structural and content model for shaping the research culture of higher education students, based on the identified characteristics and regularities. Furthermore, key ideas and recommendations for developing a research culture among future educators were formulated. DISCUSSION. The practical significance of the study is determined by the fact that the developed model for shaping a research culture can be applied during the training of pedagogical specialities.

Introduction: Juvenile idiopathic arthritis (JIA) is a persistent autoimmune-inflammatory disease that affects children younger than 16. Aggressive synovitis of the hip may cause joint destruction, hip protrusion, erosion, pseudosubluxation, dysplasia, and osteoarthritis. Subluxation of the hip had been reported previously. However, dislocation of the hip in JIA is an extremely rare situation, and only two cases have been reported up to date. Reduction of the dislocated hip has to be performed in any way. However, there is no algorithm to be followed for the treatment of hip dislocations caused by JIA. Case Presentation: In this study, we presented two cases of hip dislocation caused by JIA. Case 1: An 11-year-old boy had JIA and chronic recurrent multifocal osteomyelitis (CRMO). X-rays and computed tomography (CT) revealed a posterior dislocation of the left hip. An urgent operation was planned for the reduction of the hip. Avascular necrosis, dysplasia, or erosions were not evident at the last follow-up. Case 2: An 11-year-old girl was referred to the hospital with excessive left hip pain starting 24 h ago. A limited synovectomy with joint irrigation was performed. However, pathological examination of the synovium showed chronic inflammation consistent with JIA. On the post-operative 10th day, the patient was consulted for an increase in hip pain and deformity of the left hip. X-rays and MRI revealed posterior dislocation of the left hip with synovial hypertrophy. An urgent operation was planned. The hip could be reduced under anesthesia with mild traction, and a pelvipedal cast was applied only for 3 weeks. Avascular necrosis, dysplasia, destruction, or erosions were not evident at the last follow-up. Conclusion: For early diagnosed patient reduction under anesthesia and medial soft-tissue contracture release; for late diagnosed patient medial soft-tissue contracture release, capsulotomy and synovectomy were effective to prevent destruction and early degenerative changes of the hip joint for treatment of dislocation caused by JIA.

Introduction: Synchondrosis ischiopubic syndrome (SIS), also known as Van Neck-Odelberg disease, is a benign skeletal abnormality in children due to delayed closure in the ischiopubic synchondrosis (IPS). Patients may present with vague groin, hip, or buttock pain that can cause limitation of hip movement or limp. Few descriptions of this disorder exist, and it can easily be mistaken for other pathologies, including stress fracture, osteomyelitis, or tumor. Case Report: We report the case of a 9-year-old female gymnast presenting with right hip pain who was diagnosed with SIS. She was managed conservatively by the pediatric orthopedist. Conclusion: Van Neck-Odelberg disease is a rare cause of pediatric hip pain that can be mistaken for other more serious pathologies. The ability to recognize the disease early allows for effective treatment and the avoidance of unnecessary procedures. Keywords: Hip pain, pediatric, synchondrosis ischiopubic syndrome, Van Neck-Odelberg disease.

Published: March 2024

This research offers a comprehensive exploration of three pivotal aspects within the realm of fiber optics and piezoelectric materials. The study delves into the influence of voltage variation on piezoelectric displacement, examines the effects of bending multimode fiber (MMF) on data transmission, and scrutinizes the performance of an autoencoder in MMF image reconstruction with and without additional noise. To assess the impact of voltage variation on piezoelectric displacement, experiments were conducted by applying varying voltages to a piezoelectric material, meticulously measuring its radial displacement. The results revealed a notable increase in displacement with higher voltage, presenting implications for fiber stability and overall performance. Additionally, the investigation into the effects of bending MMF on data transmission highlighted that the bending process causes the fiber to become leaky and radiate power radially, potentially affecting data transmission. This crucial insight emphasizes the necessity for further research to optimize data transmission in practical fiber systems. Furthermore, the performance of an autoencoder model was evaluated using a dataset of MMF images, in diverse scenarios. The autoencoder exhibited impressive accuracy in reconstructing MMF images with high fidelity. The results underscore the significance of ongoing research in these domains, propelling advancements in fiber optic technology.

Published: March 2024

The complex interaction dynamics of intense femtosecond (fs) pulses and their picosecond (ps)-long leading edge with nanostructured solids occur at both the nanometer and the femtosecond scales, making them extremely difficult to measure directly. Here, we present pump-probe-based measurements that capture the ultrafast evolution of relativistically intense laser-driven grating plasma on fs time and nanometer spatial scales. We measure the transient reflectivity and spectrum of the scattered or diffracted UV-probe pulses from the grating structures with 100s of fs resolution. Our measurements capture the initial onset of the solid-to-plasma transition and the subsequent grating plasma expansion, a few ps before the peak of the intense fs pulse. We measure the instantaneous position of the electron critical surface, its velocity, and its acceleration, which are very crucial for fundamental understanding and applications in ion/electron acceleration and high harmonic generation, while also providing valuable benchmarks for simulations. Particle-in-cell (PIC) simulations corroborate the observations well offering further insight into this process.

Published: March 2024

This research extensively investigates the speed characteristics of light in a medium through the Fizeau experiment. By leveraging the particle properties of light, a physical model of particle movement in a medium is constructed to dissect the underlying physics mechanisms. The experimental data and theoretical analysis mutually corroborate, revealing the influence of the relative velocities between photons and the electric field, as well as between photons and the medium, on the speed of light in a medium. This research provides a rational justification for the Fizeau experiment and holds significant importance for the research and utilization of light.
