Unveiling the urban colonization of the Asian water monitor (Varanus salvator) across its distribution range using citizen science
Authors: Luna Álvaro , Rausell-Moreno Armand 
Published: August 2024

Background
This study aims to investigate the urban colonization of the Asian water monitor (Varanus salvator) across its entire range of distribution, addressing the paucity of research on this species in urban ecosystems. The research spans the geographic range of the Asian water monitor, focusing on urbanized areas where the species accumulates more observations (Bangkok, Colombo, Jakarta, Kuala Lumpur and Singapore).

Methods
We conducted a systematic review to comprehensively assess the current knowledge of the species’ presence in cities. Additionally, citizen science data from repositories like GBIF (Global Biodiversity Information facility ) were utilized to analyze the distribution patterns of V. salvator in urban environments. To elucidate urban distribution and correct collection biases, observations were weighted by sampling effort, using as a proxy all squamate occurrences available from 2010–2023, including V. salvator.

Results
Despite the widespread presence of the Asian water monitor in numerous cities within its distribution range, the available studies on the topic appear to be scarce. Existing research primarily consists of descriptive reports on diet and behavior. Our findings indicate that V. salvator predominantly colonizes green patches in urban areas, such as parks and small gardens. Larger cities exhibit higher records, potentially due to both permanent populations and increased citizen science reporting.

Conclusions
The Asian water monitor, as the largest lizard with established populations in cities, remains scarcely studied on a broader scale. However, the urban design of each city seems relevant to understand the distribution patterns within each context. Our study highlights the need for further research to explore the ecological and human dimensions associated with the species’ presence in urban environments.
Índice de Carencias Críticas: La razón algorítmica aplicada a la selección social
Authors: Camejo Soledad 
Published: August 2024

La discusión presentada tiene como objetivo principal la reflexión sobre las lógicas que subyacen a la incorporación de tecnologías en las políticas sociales. El artículo se encamina al análisis de la génesis del Índice de Carencias Críticas en Uruguay, como un caso particular de un algoritmo aplicado a la selección social, considerando especialmente el contexto de surgimiento, con las coordenadas institucionales dentro las cuales fue creado, así como también los discursos que han legitimado y fundamentado su creación, a partir del análisis de documentos, materiales y discursos producidos alrededor de su creación.
En ese sentido, se esbozan algunas advertencias sobre la ilusión de objetividad que se proyecta en la idea de que no hay intencionalidad detrás de las acciones y se propone que las políticas están impulsadas por visiones de mundo y ligadas a intereses que condicionan su creación.
Entre las reflexiones finales se señala que uno de los aspectos que requiere atención se vincula las competencias y potestades dentro de los procesos de construcción política. La eliminación de operaciones humanas, que es a lo que se direcciona la automatización, supone en el caso estudiado la exclusión de instancias decisorias subalternas, así como la supresión de instancias de discusión democrática y en esta exclusión parecería haber hay una nueva centralización del poder.
A Survey of the Use of Evidence-Based Health Care in Chiropractic College Clinics
Authors: Rose Kevin A. , Adams Alan 
Published: August 2024

ABSTRACT
The purpose of this article is to explore to what extent evidence-based health care (EBHC) methods are being utilized in chiropractic college clinics. A survey was mailed to the clinic administrator/director of every chiropractic college identified worldwide. The response rate was 78%. A majority of colleges required their interns to participate in oral case presentations (67%) and write case reports (65%), but only small minorities were required to generate research questions (11%) or conduct literature searches routinely (18%). No college required their interns to participate in formal journal clubs. Interns were more likely to rely on clinic faculty, preclinic class instruction, and textbooks for information on how to deal with clinic cases, rather than literature searches or health care journal articles. This study seems to show that EBHC methods are not being widely used in chiropractic college clinics worldwide. The literature suggests that EBHC can result in better patient care. EBHC methods should be incorporated into chiropractic college clinic practices. Effective strategies for implementation need to be developed, and faculty development will be required.

Published: August 2024

Background: Coronavirus disease (COVID-19) was declared a pandemic by the World Health Organization (WHO) on March 11, 2020. Fortunately and unfortunately, there are various information sources out there; medical students should have optimal knowledge of COVID-19 with all forms of education explored as they would ultimately become the future physicians.
Objectives: This current study aimed to identify the knowledge about COVID-19 amongst final year medical students and various means at which they source their information.
Methods: This was a cross-sectional study conducted amongst final year medical students in the universities in Enugu State, Nigeria. An online questionnaire was distributed amongst the respondents. The SPSS software was used for analysis with p <0.05 as significant.
Results: 84.3% of the respondents first got to know about COVID-19 from the internet amongst others; only 21.9% alluded to being adequately informed about COVID-19.
Amongst those that use the internet as their predominant source of information, about 71.7% of them use Social Media as the preferred means. The most commonly used social media was WhatsApp whereas the most trusted Social Media was Twitter.
There was a significant association between age and preferred social media for assessing information (X2=30.142; df =12; p=0.03). There was no significant association between age and medium chosen as predominant source of information (X2=2.796; df =6; p=0.834).
Conclusion and Recommendation: Final year medical students showed the expected level of information and knowledge about COVID-19. Medical educators should incorporate social media in medical education especially twitter and WhatsApp, which were the most trusted media of information sources, should be employed in the dissemination of information amongst medical students and the populace in general.
Magnetopause orientation: Comparison between generic residue analysis and BV method

Published: April 2015

AbstractDetermining the direction normal to the magnetopause layer is a key step for any study of this boundary. Various techniques have been developed for this purpose. We focus here on generic residue analysis (GRA) methods, which are based on conservation laws, and the new iterative BV method, where B represents the magnetic field and V refers to the ion velocity. This method relies on a fit of the magnetic field hodogram against a modeled geometrical shape and on the way this hodogram is described in time. These two methods have different underlying model assumptions and validity ranges. We compare here magnetopause normals predicted by BV and GRA methods to better understand the sensitivity of each method on small departures from its own physical hypotheses. This comparison is carried out first on artificial data with magnetopause‐like noise. Then a statistical study is carried out using a list of 149 flank and dayside magnetopause crossings from Cluster data where the BV method is applicable, i.e., where the magnetopause involves a single‐layer current sheet, with a crudely C‐shaped magnetic hodogram. These two comparisons validate the quality of the BV method for all these cases where it is applicable. The method provides quite reliable normal directions in all these cases, even when the boundary is moving with a varying velocity, which distorts noticeably the results of most of the other methods.
Using the level set method to study the effects of heterogeneity and anisotropy on hyporheic exchange
Authors: Chen Cheng , Zeng Lingzao 
Published: April 2015

AbstractThe level set method was used to simulate the interface movement when a conservative solute migrated from stream water to subsurface water, and study the effects of streambed heterogeneity and anisotropy on solute penetration. The level set method is a numerical technique for tracking moving interfaces based on the idea that the interface is a level set curve of a higher‐dimensional function. Numerical simulations were compared to experiments conducted in a recirculating flume. Streambed heterogeneity led to water exchange between multiple bed forms, while in homogeneous streambeds the water exchange was restricted within a single bed form. A thin layer of homogeneous sediments at the top of the heterogeneous streambeds significantly increased the interfacial water influx, resulting in faster solute penetration and stream concentration decrease. Streambed heterogeneity generated horizontal preferential flow paths in the upper part of the bed while decreasing pore water velocities deeper in the bed, which hindered vertical penetration and consequently led to slower stream concentration decrease. Decreasing vertical permeability or increasing horizontal permeability led to slower vertical penetration and stream concentration decrease. Decreasing vertical permeability had a much more significant impact on solute penetration than increasing horizontal permeability, because mass transfer in hyporheic exchange is greatly dominated by vertical advection which depends primarily on the vertical permeability. This study was the first to apply the level set method in the study of hyporheic exchange. The theoretical and numerical methods have important applications in subsurface flow and transport processes.
Water in Hawaiian peridotite minerals: A case for a dry metasomatized oceanic mantle lithosphere
Authors: Peslier Anne H. , Bizimis Michael 
Published: April 2015

AbstractThe distribution of water concentrations in the oceanic upper mantle has drastic influence on its melting, rheology, and electrical and thermal conductivities and yet is primarily known indirectly from analyses of OIB and MORB. Here, actual mantle samples, eight peridotite xenoliths from Salt Lake Crater (SLC) and one from Pali in Oahu in Hawaii were analyzed by FTIR. Water contents of orthopyroxene, clinopyroxene, and the highest measured in olivine are 116–222, 246–442, and 10–26 ppm weight H2O, respectively. Although pyroxene water contents correlate with indices of partial melting, they are too high to be explained by simple melting modeling. Mantle‐melt interaction modeling reproduces best the SLC data. These peridotites represent depleted oceanic mantle older than the Pacific lithosphere that has been refertilized by nephelinite melts containing <5 weight % H2O. Metasomatism in the Hawaiian peridotites resulted in an apparent decoupling of water and LREE that can be reconciled via assimilation and fractional crystallization. Calculated bulk‐rock water contents for SLC (50–96 ppm H2O) are on the low side of that of the MORB source (50–200 ppm H2O). Preceding metasomatism, the SLC peridotites must have been even drier, with a water content similar to that of the Pali peridotite (45 ppm H2O), a relatively unmetasomatized fragment of the Pacific lithosphere. Moreover, our data show that the oceanic mantle lithosphere above plumes is not necessarily enriched in water. Calculated viscosities using olivine water contents allow to estimate the depth of the lithosphere‐asthenosphere boundary beneath Hawaii at ∼90 km.
Shear heating and weakening of the margins of West Antarctic ice streams
Authors: Perol Thibaut , Rice James R. 
Published: April 2015

AbstractIce streams are fast flowing bands of ice separated from stagnant ridges by shear margins. The mechanisms controlling the location of the margins remain unclear. We use published ice deformation data and a simple one‐dimensional thermal model to show that West Antarctic ice stream margins have temperate ice over a substantial fraction of their thickness, a condition that may control their width. The model predicts a triple‐valued relation between the thickness‐averaged lateral shear stress and the lateral shear strain rate. Observed strain rates at the margins imply that they support slightly less lateral shear stress than adjacent ice within the stream. This requires enhanced basal resistance near the margin. We suggest, in agreement with the limited observations, the presence of a channelized drainage system at the margin that reduces the pore fluid pressure at the ice‐till interface, thus increasing the shear stress acting on the yielding Coulomb plastic bed.
Accumulation of cell‐penetrating peptides in large unilamellar vesicles: A straightforward screening assay for investigating the internalization mechanism

Published: April 2015

ABSTRACTThe internalization of cell‐penetrating peptides (CPPs) into liposomes (large unilamellar vesicles, LUVs) was studied with a rapid and robust procedure based on the quenching of a small fluorescent probe, 7‐nitrobenz‐2‐oxa‐1,3‐diazole (NBD). Quenching can be achieved by reduction with dithionite or by pH jump. LUVs with different compositions of phospholipids (PLs) were used to screen the efficacy of different CPPs. In order to “validate” the composition of the membrane models, a control cationic peptide, which does not enter eukaryotic cells, was included in the study. It was found that pure DOPG or DOPG within ternary mixtures with cholesterol are the most appropriate models for studying CPP translocation. An anionic lipid, such as DOPG, is required for the adsorption of the basic peptides on the surface of LUVs. In addition, it acts as transfer agent through the lipid bilayer. A fluid phase and/or the presence of phase defects also appear mandatory for the internalization to occur. The neutralization of charges within an inverted micelle demonstrated in the case of DOPG and also proposed for a ternary mixture of PLs might not be the only mechanism for the CPP translocation. Finally, it is shown that oleic acid facilitates the entry inside LUVs in gel phase of a series of cationic peptides including CPPs and also the negative control peptide PKCi. © 2015 Wiley Periodicals, Inc.

BACKGROUNDThe safety and efficacy of yttrium 90 (90Y) therapy for unresectable infiltrative hepatocellular carcinoma (HCC) with portal vein thrombosis (PVT) requires further evaluation.METHODSA prospective, single‐center safety and feasibility study recruited patients with unresectable (Barcelona Clinic Liver Cancer stage C) infiltrative HCC with PVT. Safety was assessed according to Common Terminology Criteria for Adverse Events version 4.0. Overall survival (OS) and time to progression (TTP) were measured from the first 90Y therapy. Survival analysis was performed with Kaplan‐Meier estimation. Prognostic factors were tested with a log‐rank test and Cox proportional regression analysis.RESULTSOverall, 45 patients were recruited, and 30 patients who met the study's inclusion criteria underwent glass‐based 90Y therapy. Four patients (13%) had transient hepatobiliary toxicity (grade ≥ 2). Ten patients (33%) had related emergency department visits, with 5 patients (17%) requiring short‐term hospitalization. No radiation pneumonitis, gastrointestinal ulceration, or procedure‐related mortality occurred. The median OS was 13 months (95% confidence interval, 4.4‐22 months) with a TTP of 9 months (95% confidence interval, 6.2‐13.1 months). Absence of ascites, an international normalized ratio < 1.2, an Eastern Cooperative Oncology Group (ECOG) performance status of 0, Child‐Pugh class A, a macroaggregated albumin lung shunt fraction (LSF) < 10%, and no hepatobiliary toxicity were significant predictors of prolonged OS according to a univariate analysis (P < .05). A multivariate analysis found an ECOG performance status of 0, Child‐Pugh class A, an LSF < 10%, and lack of transient hepatobiliary toxicity (grade ≥ 2) to be independent predictors of prolonged OS (P < .05). An ECOG performance status of 0, Child‐Pugh class A, and an LSF < 10% were also predictors of prolonged TTP according to the multivariate analysis (P < .05).CONCLUSIONSIn patients with unresectable infiltrative HCC and PVT, 90Y therapy appears to be a safe and viable therapy.

Environmentally Responsible Value Orientations: Perspectives from Public Assembly Facility Managers
Authors: Walker Matthew , Mercado Haylee 
Published: April 2015

ABSTRACTDrawing on the theories of stakeholder salience and the value‐belief norm (VBN) theory, this study examined managerial value orientations for supporting environmental responsibility. This purpose was accomplished by testing a dichotomized model of managerial value orientations, conceptualized as 'self‐interested' (performance focused) and 'other‐interested' (community focused). The hypotheses were tested among a sample of Public Assembly Facility (PAF) managers who support ER policies in this industry. The results demonstrated how the managerial value orientations influenced the hypothesized outcomes. For example, a performance‐focused stance influenced image and economic ends, while a community‐focused stance more concerned with moral obligations and localized impact. Implications are discussed in terms of how internal and external stakeholder considerations, performance concerns, community issues, and personal values toward ER are perceived by PAF managers. Accordingly, the results have implications for broad organizational theory and add to the debate over whether economic factors, social factors, or both influence ER decision‐making.

Published: April 2015

In this research, the evaluation of the pre‐heating effect on olive paste before malaxation was performed. The olive paste was treated by means of a tubular heat exchanger. The heat exchanger performances on yield and olive oil quality were evaluated considering two different types of olive paste obtained, respectively, by means of a disc crusher and a de‐pitter machine. The experimental tests were conducted on an industrial olive oil extraction plant. The results of the experimental test showed that it is possible to reduce the malaxation time by about 10 min, maintaining constant the extraction yield, when a disc crusher was used. On the other hand, using the heat exchanger to condition the de‐stoned paste, a reduction of the malaxation time compared to the control test was observed, but with significant loss in extraction yield. Concerning the olive oil quality, the flash thermal treatment of the olive paste after the crushing operation improves the phenolic and volatile compound content significantly with respect to the traditional process, in which the malaxation time has a duration of at least 30 min. By employing a tubular heat exchanger we observed some advantages, like the reduction of malaxation time and the improving of phenolic and volatile compounds.Practical applications: The practical application of this research concerns the possibility of evaluating the effects inherent in the insertion of a tubular heat exchanger before the malaxer, in an industrial olive oil extraction plant. The effects were evaluated on an industrial scale olive oil extraction plant considering these quantitative parameters: extraction efficiency of the decanter and the amount of oil lost in the husk. The olive oil quality was also evaluated. The research provides useful information to the operators of the olive oil sector and to researchers in understanding the changes manifested in the extraction plant in traditional configuration and innovative configuration with the tubular heat exchanger.A tubular heat exchanger to pre‐heat the olive paste in an industrial olive oil extraction plant.
