Detection of arsenite-oxidizing bacteria in groundwater from a gold mine under different geochemical environments
Authors:   , Kraidech Supeerapat 
Published: April 2023

Millions of people around the world potentially expose to arsenic (As) contaminated groundwater. Besides, the dominant form of As in groundwater is arsenite (As+3) and is more toxic than arsenate (As+5). This study integrated the microbial investigation, geochemical modeling, and multivariate statistical analysis to investigate the arsenite-oxidizing bacteria community from As-contaminated groundwater and its environmental influencing factors in order to understand and further develop the in-situ arsenic bioremediation technology. Microbial investigation was focusing on the detection and identification of native arsenite-oxidizing bacterial community using PCR-DGGE, cloning and sequencing of arsenite oxidase (aoxB) gene amplicons. Nine groundwater samples were collected from the gold mine and residential areas. Surface water and soil samples were also collected from upstream, within, and downstream of the gold mining area and then were compared each other. The results showed that the majority of arsenite-oxidizing bacteria was related to α-, β-proteobacteria-like clusters in which the environmental media divided them into separated clusters. Many of groundwater clones revealed affiliated to the member of β-proteobacteria class where it was contributed by Hydrogenophaga, Burkholderia, Alcaligenes, Variovorax, Thiomonas, and Cupriavidus genera. This finding implied that these native arsenite-oxidizing bacteria might play a key role in controlling an As geochemistry in As-contaminated groundwater. Moreover, PHREEQC geochemical modeling of As and multivariate statistical analysis revealed that As presented as As5+ in most groundwater samples. However, the speciations seemed to be not driven by the arsenite-oxidizing bacterial community, but geochemical charateristics of groundwater, which were pH, ORP, and DO, influence on the shape their communities significantly, while As, and Fe concentrations play a minor role.
¿Qué comparten los académicos de un grupo de investigación? Un caso de estudio crítico

The purpose of this study is to investigate the content of knowledge sharing among academics. The aim is to make an empirical contribution to a practically unresearched topic in the national (Spanish) and international context. To this purpose, an exploratory analysis based on a critical case study was proposed. Sixteen interviews were conducted with members of a research group at a Spanish public university. The results reveal that academics share elements of explicit, tacit and emotional support related to teaching, research and knowledge transfer. It has been found that the exchange refers preferentially to the field of research and that there are differences between senior and junior researchers in terms of the type of knowledge and emotional support they give and receive. This study shows that the tacit nature of knowledge can hinder its transfer and that emotional support, as part of social support, can favor knowledge sharing practices among academics.
El propósito de este estudio es investigar el contenido del intercambio de conocimiento entre los académicos. Se pretende realizar una contribución empírica a un aspecto prácticamente inédito en el contexto nacional (español) e internacional. Para ello se planteó un análisis exploratorio basado en un caso de estudio crítico. Se realizaron 16 entrevistas a miembros de un grupo de investigación de una universidad pública española. Los resultados revelan que los académicos intercambian elementos de carácter explícito, tácito y apoyo emocional relacionados con la docencia, la investigación y la transferencia de conocimiento. Se ha constatado que el intercambio se refiere preferentemente al ámbito de la investigación y que existen diferencias entre los investigadores senior y junior en cuanto al tipo de conocimiento y al apoyo emocional que dan y reciben. Este estudio demuestra que el carácter tácito del conocimiento puede dificultar su transferencia y que el apoyo emocional, como parte del apoyo social, puede favorecer las prácticas de intercambio entre los académicos.

Published: April 2023

Este artículo trata sobre la medición de la calidad en los servicios sanitarios públicos del País Vasco, cuya provisión corresponde al ente público Osakidetza – Servicio vasco de salud. Se describen métodos y herramientas de calidad generales en el ámbito de la gestión empresarial y sanitaria, junto con otras específicas de Osakidetza, a las que, estas últimas, se les dedica un análisis más profundo. En concreto, el concepto de calidad se ha estudiado desde una perspectiva poliédrica, que incluye diferentes aspectos del término, tales como la calidad contratada frente a la calidad financiada; la calidad certificada, comparada, percibida y evaluada. La principal conclusión es la constatación de la importancia que en el Servicio vasco de salud tienen los objetivos orientados a la calidad del servicio sanitario y calidad de la gestión. Estos se consiguen, entre otros, mediante el conocimiento de la percepción que tienen sus pacientes y usuarios de la atención sanitaria recibida a través de encuestas de satisfacción, así como del establecimiento de compromisos de calidad contratados que cuando son alcanzados reciben financiación específica a través de la fórmula de formalización de contratos programa.
Cooperating for a better future
Authors: Krugman Paul 
Published: April 2023

This paper addresses what I consider to be the world’s main problems, although I recognise that there are also other problems at present, such as inflation and the war in Ukraine. I will try to address the main problems, which are of interest to CIRIEC, which is an international organisation that pays particular attention to what is called the Third Sector” or “Social Economy”, an area that lies between the private business sector and the government despite I am not, I must admit, an expert in this last field. I will deal with it in the context of discussing a couple of problems we face in the world that I think are really important. The first problem is economic inequality, which I know something about. The second problem is climate change and environmental problems, which I think are the most important. I will also refer at the end to some problems related to the COVID pandemic. In all the problems, what we could call the Third Sector can play a big role.

Published: April 2023

AbstractCirculating Tumor Cells (CTCs) enrichment technology refers to medical approaches for capturing and isolating target tumor cells, which has drawn great attention owing to its applications in the clinic such as cancer diagnosis and prognosis. Magnetic nanoparticles have emerged as an important platform for CTCs capture and isolation. However, due to the inert surface nature, the molecular phenotype analysis of CTCs and identification sensitivity remain a huge challenge. Herein, an ultrasound‐activated microfluidic method is presented for rapid basic modification of magnetic nanoparticles, laying the foundation for further covalently binding of functional groups to capture CTCs. In this work, Fe3O4@SiO2 nanoparticles obtained from microfluidics are hybridized with folic acid for the capture and isolation of CTCs with folate receptors such as Hela cells. The usage of microfluidic technology to upgrade Fe3O4 nanoparticles provides the possibility for improving the detective efficiency of rare cells associated with malignancies, which sheds new light on future clinical applications.
A Bochev‐Dohrmann‐Gunzburger stabilized method for Maxwell eigenproblem

Published: April 2023

AbstractA stabilized mixed finite element method is proposed for solving the Maxwell eigenproblem in terms of the electric field and the multiplier. Using the Bochev‐Dohrmann‐Gunzburger stabilization, we introduce some ad hoc stabilizing parameters for stabilizing the kernel‐coercivity of the electric field and for stabilizing the inf‐sup condition of the multiplier. We show that the stabilized mixed method is stable and convergent, with applications to some lowest‐order edge elements on affine rectangular and cuboid mesh and on nonaffine quadrilateral mesh which fail in the classical methods. In particular, we prove the uniform convergence for guaranteeing spectral‐correct and spurious‐free discrete eigenmodes from the Babus̆ka‐Osborn spectral theory for compact operators. Numerical results have illustrated the performance of the stabilized method and confirmed the theoretical results obtained.
Trust rhetoric and CEO gender
Authors: Breuer Wolfgang , Knetsch Andreas , Salzmann Astrid Juliane 
Published: April 2023

AbstractThis study investigates the perceived and actual trustworthiness of female managers when using rhetoric to advertise their trustworthiness in public disclosure documents. We find that the stock market reacts more favorably to trust rhetoric if the document has been prepared under the responsibility of a female CEO rather than a male CEO. We rule out that this result could be driven by female and male CEOs talking about trust in different contexts. However, inconsistently with the notion that the trust rhetoric of women managers is more truthful than that of their male counterparts, trust rhetoric does not relate to less extensive earnings manipulation if such rhetoric stems from female CEOs compared to male CEOs. Our results thus do not confirm the popular view that higher female trustworthiness explains gender differences in accounting behavior.
Isotopic decoupling of K from Sr and Nd in the Saima alkaline complex, NE China: interactions of cratonic roots and asthenosphere

Published: April 2023

AbstractWe report high-precision K isotopes, apatite U–Pb ages, whole-rock elements and Sr–Nd isotopes for the Saima nephelite syenite in the North China Craton. Trace-element and Sr–Nd–Hf–O isotope data indicate the presence of subducting sediments in the source region, while K isotopic compositions show a narrow range between –0.54 ‰ and –0.28 ‰, with an average of –0.41 ± 0.06 ‰, identical to the value of the asthenosphere. The nearly identical K isotopic compositions are low probability events compared with the K isotopic compositions of island arc lavas reported previously (–1.55 ‰ to +0.2 ‰). Although crustal contamination is consistent with the Sr–Nd–K isotopic data, alternatively we propose that the isotopic data also reconcile with the interaction between cratonic roots and the underlying convective asthenosphere, if this interaction is over prolonged periods of time. Numerical simulations successfully reproduced the observed data, if the metasomatism of the lithospheric mantle root, the source of the Saima alkaline rocks, occurred 500 Ma ago. Our study reveals that the isotopic compositions of fast-diffusion components in a lithospheric mantle metasomatized by ancient subducting melts can be effectively homogenized by convective asthenosphere through diffusion over a long time interval.

AbstractObjectiveThis study evaluated audiological outcomes of stapedotomy using two different techniques, vein graft interposition and vein graft surround, for sealing the stapes fenestra.MethodA retrospective study of 130 patients who underwent stapedotomy for otosclerosis was performed. A total of 84 patients underwent the vein graft surround procedure and 46 underwent the vein graft interposition procedure. Post-operative hearing outcome was compared between them.ResultsA total of 55 of 130 patients had a post-operative air–bone gap of less than 10 dB. A total of 57 patients had an air–bone gap within 20 dB. The average air–bone gap was 13.16 dB at 3 months with a mean improvement of 22.06 dB (11.98 dB for vein graft interposition and 13.80 dB for vein graft surround; p = 0.79).ConclusionThere was no significant difference in hearing outcome between the two techniques. The vein graft interposition technique is preferred for large fenestra or stapedectomy cases and in cerebrospinal fluid gusher cases. The vein graft surround technique is easier to perform and preferred in small fenestra stapedotomy.
Children's interactions with virtual assistants: Moving beyond depictions of social agents

Abstract
Clark and Fischer argue that people see social robots as depictions of social agents. However, people's interactions with virtual assistants may change their beliefs about social robots. Children and adults with exposure to virtual assistants may view social robots not as depictions of social agents, but as social agents belonging to a unique ontological category.

Published: April 2023

AbstractObjective:To explore how sources of familial encouragement are associated with breast-feeding initiation and duration among a national sample participating in the US Special Supplemental Nutrition Program for Women, Infants, and Children (WIC).Design:This study uses the 2013–2015 WIC Infant and Toddler Feeding Practices Study 2 (WIC ITFPS-2) data. Breast-feeding initiation was measured at the first month, while duration was derived from a composite of the first 13 months. The analysis used logistic and linear regression to explore the association between encouragement sources and breast-feeding outcomes.Setting:A nationally representative sample of WIC participants in the USA.Participants:WIC participants who completed the 13-month interview of the WIC ITFPS-2 (n2807).Results:Encouragement was significantly associated with both initiation and duration. Each source of encouragement was associated with a 3·2 (95 % CI 2·8, 3·8) increase in odds of initiating breast-feeding in the unadjusted model and 3·0 (95 % CI 2·5, 3·6) increased odds, controlling for age, education, nativity, poverty status, race and ethnicity (<0·0001). When predicting log duration, each percent increase in source of encouragement was associated with an increasing duration on average by 0·003 d (95 % CI 0·2, 0·3, <0·0001). When controls were added, it was associated with an increase of an average of 0·002 d (95 % CI 0·2, 0·3) per percent increase in encouragement source (<0·0001).Conclusions:Women who receive encouragement appear to be more likely to breastfeed. Additional work is needed to explore sources of encouragement and how to include them in intervention work.
On quantification and maximization of information transfer in network dynamical systems
Authors: Singh Moirangthem Sailash , Pasumarthy Ramkrishna , Vaidya Umesh , Leonhardt Steffen 
Published: April 2023

AbstractInformation flow among nodes in a complex network describes the overall cause-effect relationships among the nodes and provides a better understanding of the contributions of these nodes individually or collectively towards the underlying network dynamics. Variations in network topologies result in varying information flows among nodes. We integrate theories from information science with control network theory into a framework that enables us to quantify and control the information flows among the nodes in a complex network. The framework explicates the relationships between the network topology and the functional patterns, such as the information transfers in biological networks, information rerouting in sensor nodes, and influence patterns in social networks. We show that by designing or re-configuring the network topology, we can optimize the information transfer function between two chosen nodes. As a proof of concept, we apply our proposed methods in the context of brain networks, where we reconfigure neural circuits to optimize excitation levels among the excitatory neurons.

Mowers versus growers: Riparian buffer management in the Southern Blue Ridge Mountains, USA
Authors: Sanders Jennifer M. , Jackson C. Rhett , Welch‐Devine Meredith 
Published: April 2023

AbstractDespite long‐standing knowledge of the benefits of riparian buffers for mitigating nonpoint source pollution, many streams are unprotected by buffers. Even landowners who understand ecological values of buffers mow riparian vegetation to the streambank. Do trends in rural riparian conditions reflect the development of riparian forest science? What motivates residential riparian management actions? Using high‐resolution orthoimagery, we quantified riparian conditions and trends between 1998 and 2015 in the rural upper Little Tennessee River basin in Macon County, North Carolina and explored how landowners view riparian zone management and riparian restoration programs. Buffer composition in 2015 was as follows: no buffer (32.5%), narrow (19.3%), forested (26.7%), shrub (7.2%), and intermediate (7.0%). Relative to 1998, the greatest decrease occurred in the no buffer class (−17.7%, 46 km) and the largest increases occurred in the shrub (+72.5%, 20 km) and narrow (12.6%, 14 km) classes. Forested buffer marginally increased. Semi‐structured interview data suggest that landowners prioritize recreational and scenic aspects of riparian buffers over ecological functions such as filtration and bank stabilization. Riparian restoration programs might be made more enticing to non‐adopters if outreach language appealed to landowner priorities, design elements demonstrated intentional management, and program managers highlighted areas where ecological goals and landowner values align.

AbstractCircular RNAs (circRNAs) play a pivotal role in the tumorigenesis and progression of various cancers. However, the role and mechanisms of circABCA13 in esophageal squamous cell carcinoma (ESCC) are largely unknown. Here, we reported that circABCA13, a novel circular RNA generated by back‐splicing of the intron of the ABCA13 gene, is highly expressed in ESCC tumor tissues and cell lines. Upregulation of circABCA13 correlated with TNM stage and a poor prognosis in ESCC patients. While knockdown of circABCA13 in ESCC cells significantly reduced cell proliferation, migration, invasion, and anchorage‐independent growth, overexpression of circABCA13 facilitated tumor growth both in vitro and in vivo. In addition, circABCA13 directly binds to miR‐4429 and sequesters miR‐4429 from its endogenous target, SRXN1 mRNA, which subsequently upregulates SRXN1 and promotes ESCC progression. Consistently, overexpression of miR‐4429 or knockdown of SRXN1 abolished malignant behavior promotion of ESCC results from circABCA13 overexpression in vitro and in vivo. Collectively, our study uncovered the oncogenic role of circABCA13 and its mechanism in ESCC, suggesting that circABCA13 could be a potential therapeutic target and a predictive biomarker for ESCC patients.
Mechanisms responsible for the onset of selective laser flash sintering of 8‐YSZ
Authors: Hagen Deborah , Beaman Joseph J. , Kovar Desiderio 
Published: April 2023

AbstractSelective laser flash sintering (SLFS) is a variation of flash sintering where the only external heat source is a scanning laser. The scanning laser locally heats a region of the sample between two electrodes, initiating measured current flow at a threshold electric field and laser energy density. This study focuses on understanding how charge transport occurs during stage I SLFS in 8 mol% yttria stabilized zirconia. Two potential charge transport mechanisms are considered: (1) a continuous current moving along a hot line between electrodes and (2) charge transported in a discrete bundle within a hot spot, localized to the area under the laser beam. Two laser scan patterns are employed to experimentally determine how charge is transported during stage I SLFS. Numerical modeling is used to estimate the temperatures at which SLFS initiates, which allows the calculation of charge carrier densities and mobilities relevant for the onset of SLFS. Results demonstrate that both a discrete bundle of charges and continuous flow of charge carriers contribute to the current at the onset of SLFS.
