Evaluating the Value of a Geology Degree: An Economic and Societal Analysis

In an era where the economic returns on investment in higher education are increasingly scrutinized, the question arises: Is a geology degree worth it? This paper tends to provide answers to this inquiry through comprehensive economic analysis to evaluate the financial viability and broader benefits of obtaining a geology degree. The analysis begins by examining the economic landscape for geologists, including their earning potential, employment opportunities, and career advancement trajectories. Data from national labor statistics, industry reports, and academic studies are synthesized to provide a nuanced understanding of the financial outcomes associated with a geology degree. Factors such as geographic location, industry specialization, and level of education are considered to capture the variability in economic outcomes among geology graduates. This paper also explores the non-monetary benefits of a geology degree, such as job satisfaction, intellectual fulfilment, and contributions to societal challenges like natural resource management, environmental conservation, and hazard mitigation. These aspects contribute to a holistic evaluation of the degree's value proposition, balancing economic returns with intrinsic rewards. Furthermore, the analysis addresses trends in the geology job market, including the impacts of technological advancements, environmental regulations, and global economic shifts on career opportunities for geologists. Insights into emerging fields within geology, such as geotechnical engineering, hydrogeology, and environmental consulting, are also discussed to illuminate evolving career pathways and specialization opportunities. Through this multidimensional examination, the paper aims to provide valuable insights to prospective students contemplating a geology degree, educators shaping curricula, and policymakers concerned with higher education and workforce development. By integrating economic principles with empirical data and qualitative perspectives, this study offers a robust framework for understanding a geology degree's economic implications and broader societal contributions in contemporary contexts.

A study of the morphological and geographical diversity of Korean indigenous buckwheat landraces for breeding

This study was carried out to explore the significance of morphology-based selection for breeding, using a case study of indigenous buckwheat landrace from Korea. Although many studies have utilized molecular methods to investigate germplasm diversity, this research underscores the often-overlooked importance of morphology-based selection in breeding strategies. Furthermore, it highlights the necessity of considering geographical information only when it accurately reflects the actual environment. The study collected and analyzed five traits from 96 samples across 27 varieties. The hypothesis was that these 27 samples might have been grouped by region due to similar environmental conditions. This hypothesis was tested using a dendrogram, clustering, correlation analysis of each trait, and PCA analysis. The results showed that morphological traits are a crucial factor in germplasm or landrace selection and that they should be considered the basic information for breeding purposes. Morphological traits were found to be random regardless of the locations where they were collected, indicating that they should be used to determine breeding targets rather than geographic locations. The study suggested that understanding the physiological traits of specific germplasm groups can accelerate breeding efforts. Overall, this study provided important insights into the selection of germplasm or landrace for breeding purposes, highlighting the importance of morphology-based selection and the need to consider environmental factors.

Optimizing defibrillator deployment with bus-mounted automated external defibrillator

ABSTRACT OBJECTIVES Early defibrillation with an automated external defibrillator (AED) can effectively improve the survival rate of patients with out-of-hospital cardiac arrest (OHCA). Placing AEDs in public locations can reduce the defibrillation response interval from collapse to defibrillation. Most public AEDs are currently placed in a stationary way (S-AED) with limited coverage area. Bus mounted AED (B-AED) can be delivered directly to the demand point. Although B-AEDs are only available during bus operating hours, they provide greater coverage area. When the number of available AEDs is insufficient, better coverage may be achieved by placing a portion of AEDs as B-AEDs. Our purpose is developing a model to determine the optimal locations of B-AEDs and S-AEDs with a predetermined number of available AEDs. The goal is to maximize the total coverage level of all demand points. METHODS We proposed a joint location model to place B-AEDs and S-AEDs based on the p-median problem (JPMP). Using data from Chang'an District, Xi'an City, China, we determined the optimal AED deployment. The performance of JPMP was compared with several other models. The coverage results of JPMP are analyzed in details, including the quantity assignment, coverage level, and geographical location of B-AEDs and S-AEDs. The impact of the bus departure intervals on coverage was also discussed. RESULTS The use of B-AEDs results in an average 98.43% increase in the number of covered demand points, and an average 74.05% increase in total coverage level. In optimal AED deployment, B-AEDs coverage follows an inverted U-shaped curve with increasing number of available AEDs. It begins to decrease when all demand points during the operating hours are covered. With a constant number of available AEDs, the total coverage level increases and then decreases as the bus departure interval increases. The larger the number of available AEDs, the smaller the optimal departure interval. CONCLUSIONS With a given number of available AEDs, combinational deployment of B-AEDs and S-AEDs significantly improves the coverage level. B-AEDs are recommended when AEDs are insufficient. If more AEDs are available, better coverage can be obtained with reasonable location of S-AEDs and B-AEDs.

Genetic diversity, population structure, and phylogenetic relationships of a widespread East Asia herb, Cryptotaenia japonica Hassk. (Apiaceae) based on genomic SNP data generated by dd-RAD sequencing.

Single-nucleotide polymorphisms (SNPs) represent the most prevalent form of genomic polymorphism and are extensively used in population genetics research. Using dd-RAD sequencing, a high-throughput sequencing method, we investigated the genome-level diversity, population structure, and phylogenetic relationships among three morphological forms of the widely distributed taxon Cryptotaenia japonica Hassk., which is native to East Asia. Our study aimed to assess the species status of C. japonica according to its genetic structure and genetic diversity patterns among 66 naturally distributed populations, comprising 26C. japonica f. japonica, 36C. japonica f. dissecta (Y. Yabe) Hara and 4C. japonica f. pinnatisecta S. L. Liou accessions. Based on genomic SNP data generated by dd-RAD sequencing, we conducted genetic diversity, principal component, neighbor-joining (NJ) phylogenetic, admixture clustering, and population differentiation analyses. The findings revealed the following: (1) 5,39,946 unlinked, high-quality SNPs, with mean π, H O, H E and F IS values of 0.062, 0.066, 0.043 and -0.014, respectively, were generated; (2) population divergence was unaffected by isolation through distance; (3) six main distinct regions corresponding to geographic locations and exhibiting various levels of genetic diversity were identified; (4) pairwise F ST analysis showed significant (P < 0.05) population differentiation in 0%-14% of populations among the six regions after sequential Bonferroni correction; and (5) three migration events (historical gene flow) indicated east‒west directionality. Moreover, contemporary gene flow analysis using Jost's D, Nei's G ST, and Nm values highlighted the middle latitude area of East Asia as a significant contributor to genetic structuring in C. japonica. Overall, our study elucidates the relatively low genetic differentiation and population structure of C. japonica across East Asia, further enhancing our understanding of plant lineage diversification in the Sino-Japanese Floristic Region.

Moderating effects of socioeconomic status and geographical location on the Health4Life school-based intervention

ObjectiveThis study evaluated the moderating effects of socioeconomic status (SES) and geographical location on the efficacy of an eHealth school-based multiple health behaviour change intervention – Health4Life – in targeting alcohol and tobacco use, dietary intake, knowledge, behavioural intentions, and psychological distress over 24-months. MethodsData from the Health4Life cluster-randomised controlled trial conducted from 2019 to 2021 in 71 Australian secondary schools were analysed (N=6639; baseline age 11-14yrs). Schools were from metropolitan (89%) and regional (11%) areas, and participants’ SES was classified as low (15%), mid (37%), and high (48%) relative to the study population. Primary outcomes included alcohol and tobacco use, and a composite indicator of poor diet. Secondary outcomes were knowledge, behavioural intentions, and psychological distress. Latent growth models assessed moderating effects of SES and geographical location on between-group change over 24-months. ResultsGeographical location moderated the intervention’s effect on odds of reporting a poor diet (OR = 1.79, 95% CI = 1.32–2.43, p < 0.001) and diet-related behavioural intentions (OR = 0.71, 95% CI = 0.56–0.89, p = 0.024) over time. Subset analyses indicated that intervention participants in regional areas had higher odds of reporting a poor diet (OR = 1.61, 95% CI = 1.13–2.29, p = 0.008), while those in metropolitan areas had higher odds of improving diet-related behavioural intentions (OR = 1.13, 95% CI = 1.01–1.27, p = 0.041), compared to the control group. No other significant moderation effects were observed. ConclusionsWhile significant disparities were generally not observed, the geographical differences in intervention effects on diet and diet-related intentions suggest that co-designed and tailored approaches may benefit disadvantaged adolescents to address the disproportionately high rates of lifestyle risk behaviours among these priority populations.

U–Pb–Hf and morphological evolution of zircon from granites associated with world-class tungsten skarn deposits in the northern Canadian Cordillera

The northern Canadian Cordillera is the most significant tungsten district in North America. Here, high-grade tungsten skarn deposits are associated with small, reduced, high-K calc-alkaline, S-type biotite granite plutons belonging to the 102–96 Ma Tungsten plutonic suite (TPS). A detailed U–Pb–Hf and morphological study of magmatic zircon from plutons in the southern half of the TPS belt was undertaken to better understand magmatic processes leading to the generation of the associated tungsten deposits. Antecrystic zircon from the TPS plutons began crystallizing during a transpressional regime ca. 117 Ma, suggesting the TPS magmas were active for up to 21 Myr prior to their upper crustal emplacement and final crystallization. This prolonged magmatic activity necessitates a magma origin in long-lived, deep crustal magma chambers. Hafnium isotopic compositions in zircon for the southern TPS as a whole form a non-radiogenic, univariate, and relatively wide ranging population (εHfi = −17.6 ± 4.5), but U–Pb–Hf trends become apparent when the data are sub-divided into sample groups with similar age, zircon morphology, and geographic location. These evolutionary trends in magmatic zircon are most simply explained by interactions between the parent melt and dissolving inherited zircon grains. This, along with changing zircon morphology, is consistent with gradual cooling and crystallization pathways exhibited by S-type magmas. Differing evolutionary trends in the U–Pb–Hf isotopic data between sample groups, however, suggest there were multiple magma batches that evolved independently, possibly in separate pockets within large, deep magma chambers. Zircon morphologies also suggest some grains in all sample groups were equilibrated with hotter and more alkaline magmas, although there is no textural or compositional evidence in the zircon for mixing of magmas with widely different compositions. An unconstrained inversion of local aeromagnetic data indicates reduced batholiths could be present 4–6+ km below the surface and that the plutons are apophysies to (or, higher level injections from) these deeper bodies. Although these batholiths can only be short-term holding chambers for magmas ascending from deep crustal levels, they may have been important for the segregation of mineralizing fluids. Since no single magmatic evolutionary pattern in the unaltered TPS plutons can be definitively linked to tungsten mineralization, pulses of mineralizing fluid may have been derived instead from the underlying batholiths. The 20+ Myr duration of deep magmatic activity exhibited by the TPS is similar to timeframes suggested for magmas associated with tungsten deposits in southern China, and may have allowed extended fractionation of a large volume of crustally derived magma to concentrate tungsten into late-stage melts. The emplacement of upper crustal batholiths and plutons in both regions during or following a transition to an extensional tectonic regime suggests the relaxed geodynamic regime may have been important in the ascension of metal-rich magmas and (or) fluids, ultimately resulting globally important tungsten deposits.

Contribution of artificial intelligence for understanding animal rabies epidemiology in Morocco: What are the perspectives of an innovative and predictive approaches?

Rabies is a major zoonotic disease legally notifiable in Morocco and elsewhere. Given the burden of rabies and its impact on public health, several national control programs have been implemented since 1986, without achieving their expected objectives.The aim of this study was to design a predictive analysis of rabies in Morocco. The expected outcome was the construction of probabilistic diagrams that can guide actions for the integrated control of this disease, involving all stakeholders, in the country. Such modeling is an essential step in operational epidemiology to optimize expenditure of public funds allocated to the integrated strategy for fighting this disease.The methodology employed combined the use of geospatial analysis tools (kriging) and artificial intelligence models (Machine Learning). In order to investigate the link between the risk of rabies within a territorial municipality (commune) and its socio-economic situation, the following data were analyzed: (1) health data: reported animal cases of rabies between 2004 and 2021 and data obtained through the ArcGIS kriging tool (Geospatial data); (2) demographic and socio-economic data. We compared several Machine Learning models. Of these, the “Imbalanced-Xgboost” model associated with kriging yielded the best results. After optimizing this model, we mapped our results for better visualization.The obtained results complement and consolidate previous study in this field with greater accuracy, showing a strong correlation between a commune's socio-economic status, its geographical location and its risk level of rabies. From this, 399 out of the 1546 communes have been identified as high-risk areas, accounting for 25.8% of the total number of communes. Under this risk-based approach, the results of these analyses make it practical to take targeted decisions for rabies prevention and control, as well as canine population control, in a territorial commune according to its risk level. Such an approach allows obvious optimized distribution of financial resources and adaptation of the control actions to be taken.The study highlights also the importance of using innovative technologies to refine epidemiological approaches and fill gaps in field data. Through this study, we hope to contribute to eradication of rabies in Morocco by providing reliable data and practical recommendations for control actions against rabies.

Intra-Phenotypic and -Genotypic Variations of Beauveria bassiana (Bals.) Vuill. Strains Infecting Aedes aegypti L. Adults.

Beauveria bassiana has potential for Aedes aegypti biological control. However, its efficacy depends on the strain's geographic location, host susceptibility, and virulence. The present study aimed to evaluate the effectiveness of B. bassiana strain BBPTG4 conidia in controlling Ae. aegypti adults and its detection via introns profile on exposed mosquito corpses. Morphologic characteristics among strains were highly similar. Comprehensive testing of these strains demonstrated that BBPT4 exhibited the ideal biological activity for Ae. aegypti control, with a median lethal time (TL50) of 7.5 d compared to ~3 d and ~10 d for BB01 and BB37 strains, respectively. Infected mosquitoes died after GHA and BBPTG4 exposure, and corpses were analyzed for infecting strains detection. Differences among the seven evaluated strains were determined, assessing five different insertion group I intron profiles in BBTG4, BB01, GHA, BB37, and BB02 strains. Mosquitoes infected by BBPTG4 and non-exposed (negative control) intron profiles were obtained. We detected the presence of introns in the BBPTG4 strain, which were not present in non-exposed mosquitoes. In conclusion, B. bassiana strains showed similarities in terms of their cultural and microscopic morphological characteristics and biologicals virulence level, but different intron profiles. BBPTG4 strain-infected Ae. aegypti adult corpses, showing specific amplicons, enabled us to identify B. bassiana at the strain level among infected mosquitoes. However, monitoring and detection of field-infected insects is essential for further verification.

Telehealth visit type and patient-reported outcomes among patients with cancer

BackgroundRelaxed licensing restrictions on telehealth use during the COVID-19 pandemic allowed broad use irrespective of visit type. As these telehealth waivers expire, optimal uses of telehealth must be assessed to inform policy and clinical care. We evaluated patient experience associated with telehealth and in-person new or established visits. MethodsPatients seen in-person and via telehealth for urologic cancer care from August 2019 to June 2022 received a survey on satisfaction with care, perceptions of communication during their visit, travel time, travel costs, and days of work missed. We assessed survey responses with descriptive statistics. ResultsSurveys were completed for 1,031 patient visits (N = 494 new visits, N = 537 established visits). Satisfaction rates were high for all visit modalities among new and established patients (mean score range 59.9–60.7 [maximum 63], P > 0.05). Patient-rated quality of the encounter did not differ by visit type and modality (P > 0.05, for nearly all comparisons). New in-person patient visits were associated with significantly higher travel costs (mean $496.10, SD $1021) compared with new telehealth visits (mean $26.60, SD $141; P < 0.001); 27% of new in-person patients required plane travel and 41% required a hotel stay (P < 0.001 vs. 0.8% and 3.2% of new telehealth patients, respectively). ConclusionsSatisfaction outcomes among patients with urologic cancer receiving new patient telehealth care equaled those of new patients cared for in-person while costs were significantly lower. Offering telehealth exemption beyond COVID-19 licensing waivers to include new patient visits would allow for ongoing delivery of high-quality urologic cancer care irrespective of geographic location.

Influence of sea surface waves on numerical modeling of an oil spill: Revisit of symphony wheel accident

The greatest purpose of this study is to analyze the importance of surface waves on the hindcasting of the oil spill through the Symphony wheel accident in the Qingdao coastal waters. During the accident period, a total of four synthetic aperture radar (SAR) images by Gaofen-3 (GF-3) were acquired from 2 to 19 May 2021. The hindcasting of two sea surface dynamics, namely currents and waves, is carried out using a coupled marine numeric model. This model, known as the finite-volume community ocean model-simulating waves nearshore (FVCOM-SWAVE), employs a triangular grid. Simulated significant wave height (SWH) is validated against remotely sensed product by the Haiyang-2B (HY-2B) altimeter on April 2021 yields a root mean square error (RMSE) of 0.38, a correlation coefficient (COR) of 0.78, and a scatter index (SI) of 0.34. Subsequently, Stokes drift estimated by waves are included to hindcasting oil spills using the oil particle-tracing method. The bias of the spatial coverage (SAR minus simulations) of an algorithm called the constant false alarm rate (CFAR) is −73.92 km2 with Stokes drift, which is significantly less than the 55.45 km2 coverage without Stokes drift. Moreover, compared with model-simulated oil spills, the bias of the geographic location at the center point with Stokes drift is 8.18 km, which is less than the 12.95 km bias without Stokes drift. These results demonstrate that Stokes drift needs to be included in the prediction of oil spills.

Neuropelveology for Endometriosis Management: A Systematic Review and Multilevel Meta-Analysis.

Background: Despite the availability of treatments such as surgery and hormonal therapy, women with endometriosis often endure chronic problems. This review aims to evaluate the effectiveness and safety of neuropelveology. Methods: In a systematic review with a meta-analysis, we searched three electronic databases: MEDLINE (PubMed), Scopus, Embase, and Web of Science (WOS). The search was conducted in January 2024 with no date or language restrictions using a carefully curated set of keywords. We conducted a comprehensive review, including all observational and clinical trials reporting data on neuropelveology approaches in the management of endometriosis, irrespective of geographical location. The studies included in our review were required to be published in peer-reviewed journals and be available in any language, with at least an abstract in English. The data of all included studies were summarized in excel (version 19) and were analyzed by Comprehensive Meta-analysis v3.3 (Biostat) and STATA (version 17). A multilevel meta-analysis was performed on studies with two arms (intervention and control) to evaluate the efficacy of neuropelveology in managing women with endometriosis. Results: After screening 476 records, 30 studies, published from 1952 to 2021, were included in this review, each employing various methodologies. The studies were divided into the following three categories: (a) efficacy of neurectomy or nerve resection (n = 20), (b) efficacy of neurolysis (nerve blocks) (n = 4), and (c) efficacy of neuromodulation (n = 6) in the management of endometriosis. Among the studies evaluating the efficacy of neurectomy or nerve resection, 10 studies (with 18 group comparisons) were included in the random-effects meta-analysis. Treatment success (not occurrence of pain) was higher with neurectomy vs. controls (RR = 0.497, 95% CI = 0.236 to 1.04, p = 0.06 (for experimental studies) and RR = 0.248, 95% CI = 0.14 to 0.43, p < 0.001 (for observational studies)), representing a 50% and 75.2% risk reduction in the recurrence of pain in experimental and observational studies, respectively. Similarly, neurolysis, particularly superior hypogastric plexus blocks and uterine nerve ethanol neurolysis, demonstrated encouraging outcomes in pain reduction and an improved quality of life for women with endometriosis. The efficacy of neuromodulation in managing endometriosis symptoms appears promising but requires further investigation. Conclusions: In conclusion, neuropelveology approaches, such as neurectomy, neurolysis, and neuromodulation, offer significant potential for pain reduction in endometriosis patients, albeit with risks of complications and high recurrence rates, necessitating careful patient selection and long-term monitoring.

Multimodal urban mobility solutions for a smart campus using artificial neural networks for route determination and an algorithm for arrival time prediction

Artificial intelligence algorithms play a key role in solving multimodal urban mobility problems, this study outlines a scheme covering bus, boat, and pedestrian transport modes. This involves designing an Artificial Neural Network (ANN) model to classify the most suitable routes for passengers, together with an algorithm capable of estimating the arrival times of various transportation modes at designated stopping points or buildings within the smart campus. The information used to train the ANN is obtained from an Internet of Things (IoT) network and a database that includes the available routes within the campus (which is situated in the Brazilian Amazon), where there is a multimodal electric mobility service. In seeking to achieve the objectives, this ANN relied on the user's geographic location in the input layer, and route mapping data stored in the database in the output layer, as well as the backpropagation algorithm for computational processing and adjustments of synaptic weight. The algorithm for modal arrival time prediction used real-time geographic location data, together with the Haversine formula to calculate geographic distance, while the average speed was obtained from the IoT network. A range of different ANN parameters were included in the experiments. In the study case, the ANN results show an improvement of above 92% for determining the best routes and predicting arrival times. The findings show that ANNs can effectively find the best route within a real-world smart campus environment. Moreover, the results show the arrival time can be estimated by using real-time geographic location data.

Current status of etiology and outcomes of acute liver failure in India-A multicentre study from tertiary centres.

Acute liver failure (ALF) is a medical emergency and liver transplantation (LT) may be required as definitive therapy. The etiology varies across geographical locations and is mostly viral dominant in India. We aimed at evaluating the spectrum, impact of interventions (plasma exchange [PLEx], continuous renal replacement therapy [CRRT]) and outcomes of ALF in India in recent times. A multicentre retrospective study across four major tertiary care centres. As many as 183ALF patients (median age, 23years; females, 43.1%; model for end-stage liver disease [MELD], 32.7) from January 2021 to December 2023 were included. Nineteen percent had infection and 40.4% of patients satisfied King's College criteria (KCC) at admission. Most common cause for ALF was hepatitis A virus (HAV) (44.2%) followed by rodenticide poisoning (10.3%). Approximately 35% of patients each received either PLEx or CRRT. The 7, 14 and 21-day transplant-free survival probability was 65.5%, 60.1%, and 57.3%, respectively. Only 3.8% of patients underwent liver transplantation. On multivariable Cox regression analysis, hemoglobin (HR, 0.74 [0.63-0.87]), lactate (HR, 1.14 [1.03-1.26]), advanced hepatic encephalopathy (HE) (HR, 4.87 [1.89-12.5]) and fulfilling KCC [HR, 10.04 [4.57-22.06]) at admission were the independent predictors of mortality. A model including KCC + lactate + HE ≥ 3 with or without hemoglobin had an AUROC of 0.81-0.84 to predict mortality. In those who underwent PLEx, advanced HE (HR, 4.13 [1.75-9.7]), procalcitonin (HR, 1.18 [1.07-1.30]) and KCC (HR, 4.6 [1.6-13.1), while for those who received CRRT, lactate (HR, 1.37 [1.22-1.54]) and KCC (HR, 6.4 [2.5-15.8]) independently predicted mortality. Hepatitis A virus is currently the most common cause for ALF in India, emphasizing the need for universal vaccination programmes. Spontaneous survival in tertiary care centres is 57%. LT rates were low.

Are There Non-Business Days for Crime? A Small-Area Bayesian Spatiotemporal Analysis of Crime Patterns

ABSTRACT Criminal behavior may be different on weekends and holidays compared to business days. Understanding the distinctive crime patterns on non-business days is useful for crime research and crime control. This study contributes to the literature by explicitly investigating the small-area spatiotemporal variation in five types of major crimes between business days and non-business days using a Bayesian modeling approach in Old Toronto, Canada. The results show that criminal activity varies between business days and non-business days, influenced by the types of crimes, geographic locations, and local neighborhood characteristics. Compared to business days, on non-business days, southern areas with high business and entertainment activity exhibit increased assault and robbery levels, while northern residential areas experience reduced activity of break and enter, auto theft, and theft over $5,000. Nonetheless, spatial crime hot spots generally remain consistent between the two date categories, with some hot spots presenting an exacerbation of criminal activity during non-business days. A few sociodemographic variables and built environment features are associated with the spatiotemporal variation in crime. These findings demonstrate the spatiotemporal variation in criminal behavior and crime patterns between business days and non-business days and highlight the need for customized crime control measures at the small area level.

Ligand-selective turn-off sensing, harvesting and post-adsorptive use of Dy(III) and Yb(III) by intrinsically fluorescent flower-shaped Gum Acacia-grafted hydrogels

Rare earth metals (REMs), such as Dysprosium (Dy) and Ytterbium (Yb), have experienced unprecedented demand in recent times due to their applications in high-end technologies. REMs are found only in select geographic locations placing tremendous economic constraints on their use. In this work, we have developed Gum Acacia-grafted hydrogels (GmAc-FluoroTerPs) that are capable of selective detection and capture of Dy and Yb. The intrinsically blue fluorescent polymer hydrogel GmAc-FluoroTerP has been optimized for Dy(III) and Yb(III) specific quenching, enabling limit of detection of the REMs at 0.13 nM and 60.8 pM, respectively. A comprehensive structural characterization of the fluorescent hydrogel has been performed via NMR, FTIR, XPS, EPR, TGA, XRD, TEM, SEM, EDX, TCSPC, and DLS. In addition to an in situ generated fluorophore, GmAc-FluoroTerP displays a distinctive aggregation induced emission enhancement in mixed solvents. The complexation of Dy(III)/Yb(III) with GmAc-FluoroTerP hydrogel has been characterized by XPS, TCSPC, and logic gate analyses, and the adsorptive capacity for Dy(III) and Yb(III) are found to be best reported till date as 125.57 mg g−1 and 102.27 mg g−1, respectively. Desorption at acidic pH allows recovery of the REMs. We also report semiconducting behaviour of the native fluorescent hydrogel, that is enhanced upon adsorptive capture of Dy(III) and Yb(III), with calculated band gaps at 1.37, 0.77, and 0.49 eV, respectively. The convergent sensing, capture, and reuse of Dy(III) and Yb(III) presented in this work promises a hitherto unreported template for application on other REMs.

A comprehensive perspective on local drivers in community-based health tourism industry development: a qualitative study of Mazandaran Province, Iran

BackgroundHealth tourism is an important component that may influence the direction of development in a region. Mazandarn, Iran, is recognized as a highly sustainable market in the region because of its abundant natural resources, temperate temperature, and strategic geographical location. Therefore, considering the importance of health tourism and its existing potential in Mazandaran, Iran, this study was conducted with the aim of exploring a comprehensive perspective on local drivers in community-based health tourism industry development and factors affecting the attraction of health tourism.MethodsWe conducted this study in Mazandarn, Iran, using a qualitative approach. Participants included a sample of Iranian people, aged 34–54 years, with previous history of health tourism or expert in it. Participants were selected from three different categories of the community: academic professionals in health tourism, managers in health tourism, and health tourists. Data were obtained via semi-structured in-depth interviews and focus group discussions. Inductive qualitative content analysis was used to converge and compare themes through participant data. The interviews kept going until data saturation was achieved.ResultsBased on our findings, we distilled local drivers in community-based health tourism industry development into five main categories and 30 subcategories: (Sharifabadi AM, Ardakani FA. A model for health tourism development using fuzzy TOPSIS and interpretive structural modeling in Yazd province. J Health Adm (JHA). 2014;17:55.) infrastructure and resources; (Hemmati F, Dabbaghi F, Mahmoudi G. Investigating the impact of Information Technology on the status of Health Tourism in Mashhad, Iran. Revista Publicando. 2018;5(15):54–65.) tourist attractions; (Sarabi Asiabar A, Rezapour A, Raei B, Tahernezhad A, Alipour V, Behzadifar M. Economic, Cultural, and Political Requirements for Medical Tourism Development in Iran: Insights from a Fuzzy Analytical Hierarchy Process Method. Med J Islamic Repub Iran. 2022;35:199.) socio-cultural contexts; (Mosadeghrad AM, Sadeghi M. Medical tourism: Reasons for choosing Iran. Payesh (Health Monitor). 2021;20(2):145–66.) economic-financial factors; and (Manna R, Cavallone M, Ciasullo MV, Palumbo R. Beyond the rhetoric of health tourism: shedding light on the reality of health tourism in Italy. Curr Issues Tourism. 2020;23(14):1805–19.) political-communicative factors. The findings of the study showed that, from the participants’ point of view, although there are several strategies, such as the development of public service and tourism infrastructure, increasing tourist attractions, and formulating appropriate policies and procedures for the development of health tourism, they are also faced with many challenges, especially political, economic, and cultural challenges.ConclusionThis study showed that improving infrastructure and resources, promoting tourist attractions, informing socio-cultural contexts, improving economic and financial capacity, and developing political and communicative contexts might increase the attraction of health tourists. The suggested components are not contextually driven, although empirical outcomes may differ based on the level of service offerings in health tourism locations.

Evidence of Differential Attainment in Canadian Medical School Admissions: A Scoping Review.

In Canada, many groups (e.g., Black, Indigenous, rural backgrounds) have historically faced and continue to encounter systemic barriers in accessing the medical profession. These barriers often manifest in performance disparities, known as differential attainment, during medical school admissions. This scoping review summarizes the nature and extent of evidence on the association of differential attainment in medical school admissions selection tools and outcomes with applicant social identity in the Canadian context. The authors used Arksey and O'Malley's scoping review framework to summarize research studies published between 2000-2022 with empirical evidence of differential attainment in admissions selection tools and outcomes with respect to a range of applicant social identity categories. The authors recorded whether studies adopted a structuralist and/or intersectional perspective. Ultimately, 15 studies were included in the review. While the evidence on differential attainment associated with social identity in Canadian medical education was heterogeneous, numerous studies highlight differential attainment in the admissions process associated with applicant race and/or ethnicity (6 studies), age (5 studies), gender (4 studies), socioeconomic status (3 studies), geographic location (4 studies), and rural or urban background (5 studies). These attainment differences were reported at 3 phases of the admissions process (invitation to interview, offer of admission, and acceptance of offer), and were driven by several admissions selection tools, including grade point average, Medical College Admission Test score, and interview performance. The review highlights evidence that suggests systemic, structural inequities in admissions systems manifest as differential attainment in Canadian medical school admissions. Based on this evidence, those who identify as Black or Indigenous and those with low socioeconomic status or rural backgrounds were generally more adversely affected. Admission practices must be studied and improved so medical education systems can better avow equality and human dignity and achieve equity goals.

Cover crop mixtures do not assemble markedly distinct soil microbiotas as compared to monocultures in a multilocation field experiment

Cover crops are used in cropping systems to enhance ecosystem services, such as soil resilience to erosion or microbial activity. Different cover crops are selected to steer specific processes, but whether cover crop mixtures have an added value over monocultures remains debated. Here, we investigated if cover crop mixtures accumulate soil microbiotas distinct from those of monocultures, potentially leading to more varied microbially-driven soil functions. We performed a field experiment at three locations in the Netherlands, each including nine cover crop monocultures, five- and eight-species mixtures, and a fallow control. After three months, we measured cover crop biomass and profiled soil bacterial, fungal, and arbuscular mycorrhizal fungal communities via amplicon sequencing. The different crop monocultures produced similar biomass across all three locations, and mixtures had average productivity compared to monocultures. The diversity and community structure of soil microbial communities was primarily determined by the geographical location, and then by cover crop treatment at each location. Although the cover crop species affected the soil microbiome differently, cover crop mixtures did neither increase microbial diversity nor the overall community differentiation compared to monocultures. Our results suggest that mixing cover crop species does not significantly influence microbially-driven soil functions, at least in short-term crop rotations.

Cultural Representations in Border Literature: Reflecting on Harka Gurung’s Vignettes of Nepal

This article explores the issues raised in Harka Gurung’s Vignettes of Nepal and analyzes them from historical perspectives. Cultural activities of the different geographical locations of Nepal that Gurung explores in the book are based on border, culture and the literature. Culture is a part of social practices interlinked to the cultural activities that connect people and literature of a society or a cultural community under a chain of social/socio-cultural activities. There might be different kinds of cultural groups within the same geographical border but they have the same kind of humanitarian values. However, they have some conflicting borders because of the space on performances and understanding of the cultural critics. Here, border refers to both the cultural community’s line as well as geographical territory. Many people respect to each-other’s culture but some of them disrespect borderland culture and literature that creates social disharmony in the name of cultural identity. Culture is a part of literary activities that helps to generate the literature and every literature is based on the culture. Gurung’s Vignettes of Nepal incorporates twenty essays based on different geographical borderlands, cultural practices and literature. He begins his essays from west of Kathmandu and concludes them coming to the east. In this study, this researcher selects particularly a few essays based on cultural borderland. Border, culture and literature are inseparable and so this study is on cultural cum ethno-geographical methodology as it studies the behavioral things of the people of different cultural communities. Objective of this paper is to show the connectivity of literature in the cultural borderland. To achieve the research goal, this study centers on historical places and observes cultural practices in Nepal. This researcher applies Mary Anderson and Dor Bahadur Bista’s ideas as supporting tools to the research in addition to Shalom H. Schwartz’s theory based on universal human values and cross-cultural psychologies. Finding of this paper is that the humanitarian cultures of the borders are key subjects to create the socio-cultural harmonies that help to generate the literature.

Temporal stability of sex ratio distorter prevalence in natural populations of the isopod Armadillidium vulgare.

In the terrestrial isopod Armadillidium vulgare, many females produce progenies with female-biased sex ratios due to two feminizing sex ratio distorters (SRD): Wolbachia endosymbionts and a nuclear non-mendelian locus called the f element. To investigate the potential impact of these SRD on the evolution of host sex determination, we analyzed their temporal distribution in six A. vulgare populations sampled between 2003 and 2017, for a total of 29 time points. SRD distribution was heterogeneous among populations despite their close geographic locations, so that when one SRD was frequent in a population, the other SRD was rare. In contrast with spatial heterogeneity, our results overall did not reveal substantial temporal variability in SRD prevalence within populations, suggesting equilibria in SRD evolutionary dynamics may have been reached or nearly so. Temporal stability was also generally reflected in mitochondrial and nuclear variation. Nevertheless, in a population, a Wolbachia strain replacement coincided with changes in mitochondrial composition but no change in nuclear composition, thus constituting a typical example of mitochondrial sweep caused by endosymbiont rise in frequency. Rare incongruence between Wolbachia strains and mitochondrial haplotypes suggested the occurrence of intraspecific horizontal transmission, making it a biologically relevant parameter for Wolbachia evolutionary dynamics in A. vulgare. Overall, our results provide an empirical basis for future studies on SRD evolutionary dynamics in the context of multiple sex determination factors co-existing within a single species, to ultimately evaluate the impact of SRD on the evolution of host sex determination mechanisms and sex chromosomes.
