Wave-Forced Hydrogeology and Diagenesis, Tague Reef, St. Croix, U.S. Virgin Islands.

Wave driven pressure variations in reef porewater were used to investigate the physical processes that affect early marine carbonate cementation in a bankbarrier reef. Cores taken along a transect, and porewater geochemistry sam pled from wells were used to characterize sedim entary and geochemical environments. The cores show an Acropora palmata framework with a patchily cem ented sandy matrix com poses the forereef and reef crest, with dominantly loose sedim ents in the backreef. Hydraulic conductivities a re approximately 1x1 O'4 m/s. The wave climate is m oderate, with up to 75 % wave height attenuation across the reef crest. Porewater p ressure variations correspond to surface waveforms, and are attenuated with increasing depth. Hydraulic head gradients are approximately 0.01. The resulting instantaneous porew ater velocities are about 1x10*6 m/s. Time series of pressure variations su g g est flow is dominantly oscillatory, with no apparen t net motion. Shallow reef porewater is well oxygenated and supersaturated for aragonite or Mg-calcite. Deeper porewater becom es nearly anoxic, with som e sulfate reduction, both due to biological respiration. A corresponding decrease in pH causes carbonate saturation values also to decrease , limiting the potential for cementation to the shallow reef surface. Oxide and sulfide coatings on sedim ents are thought to reflect porewater redox conditions. The distribution of coatings suggests deeper porew ater exchange in the forereef and reef crest than in the backreef. Modeling of symmetrical and asymmetrical linear wave motion suggests net advective transport is negligible. Instead, mechanical dispersion is believed to dominate porewater exchange p ro cesses . Gradients from wave generated setup, tides and infragravity waves also drive porew ater circulation, and may contribute to porewater exchange.
Long-Term Efficacy and Safety of Anlotinib as a Monotherapy and Combined Therapy for Advanced Sarcoma

Objective To analyze the effectiveness of the long-term (> 12 months) administration of anlotinib as a monotherapy or combined therapy in patients with advanced sarcomas. Methods A retrospective analysis was conducted of patients with advanced sarcomas with measurable target lesions since 2018. Twenty-two of the patients had taken anlotinib regularly for > 12 months. The patients’ general information and the drug’s clinical efficacy and toxicity data were collected and statistically analyzed using RECIST 1.1 to measure the target lesions and tumor PFS time as the main endpoints. We used a swimmer plot to observe the drug’s efficacy and duration, and employed a waterfall plot to express the best treatment effect. Results The study included 14 male and 8 female patients, ranging in age from 14 to 75 (mean: 44.82) years. The primary diseases included alveolar soft part sarcoma, synovial sarcoma, leiomyosarcoma, and others. The metastasis sites were the lungs in fifteen cases, lymph nodes in four cases, and multiple sites in three cases. Fourteen patients had previously undergone chemotherapy. The current therapy protocol was oral anlotinib alone for nine cases, combination chemotherapy for nine cases, and combination immunotherapy (anti-PD-1) for four cases. The highest clinical efficacy was complete remission (CR) in four (18.18%) cases, partial response (PR) in five (22.73%) cases, and stable disease in 13 (59.09%) cases, with an odds ratio of response of 40.91%. The mean PFS for the CR, PR, and stable disease groups was 16.50, 14.50, and 29.31 months, respectively (p < 0.05). The main adverse effects included hand-foot syndrome, hypertension, and leukopenia. Conclusion Anlotinib monotherapy or combination therapy can be more effective and safer for certain advanced sarcomas, with more extended maintenance and acceptable side effects. Clinical efficacy at the CR and PR levels might predict the long-term PFS in certain advanced sarcomas.
Development of Landmark Use for Navigation in Children: Effects of Age, Sex, Working Memory and Landmark Type

The use of landmarks for navigation develops throughout childhood. Here, we examined the developmental trajectory of egocentric and allocentric navigation based on landmark information in an on-screen virtual environment in 39 5–6-year-olds, 43 7–8-year-olds, and 41 9–10-year-olds. We assessed both categorical performance, indicating the notion of location changes based on the landmarks, as well as metrical performance relating to the precision of the representation of the environment. We investigated whether age, sex, spatial working memory, verbal working memory, and verbal production of left and right contributed to the development of navigation skills. In egocentric navigation, Categorical performance was already above chance at 5 years of age and was positively related to visuo-spatial working memory and the production of left/right, whereas metrical performance was only related to age. Allocentric navigation started to develop between 5 and 8 years of age and was related to sex, with boys outperforming girls. Both boys and girls seemed to rely more on directional landmark information as compared to positional landmark information. To our knowledge, this study is the first to give insight into the relative contribution of different cognitive abilities to navigation skills in school-aged children.
Distance education students’ acceptance of online learning systems, attitudes towards online learning and their self-directed learning skills

About four million people living in Turkey or abroad with a Turkish passport enrolled in distance education schools to have the opportunity to complete their compulsory formal education in the spring of 2018-19. The aim of this descriptive study was to determine distance education students’ acceptance of online learning systems, their attitudes towards online learning, and their self-directed learning skills and the relationship between them. The study group consisted of 1233 students in the spring term of 2018-2019. Some of the main results are as follows: A six-variable model (perceived ease of use, perceived usefulness, general acceptance, individual awareness, usefulness, application effectiveness) played a significantly explanatory role in dependent variables (subscales of self-directed learning skills). Perceived usefulness and usefulness positively predicted motivation, suggesting that the higher the perceived usefulness, the higher the motivation. General acceptance and application effectiveness negatively predicted self-monitoring. Female participants were more motivated by online learning environments than males.

Antecedents of Work Engagement in the Public Sector: A Systematic Literature Review

This article systematically reviewed the body of literature concerning work engagement in public organizations, aiming to examine the antecedents of work engagement in the public sector. Web of Science and Scopus, two prominent journal databases, were utilized to identify relevant literature. Adopting the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) approach, a final of 48 articles were systematically analyzed as research samples. The review identified five main themes: organizational and team factors, perceived leadership, job-related experience, individual, and organizational intervention factors. Generally, most studies reviewed emphasized individual and job-design-related factors as antecedents of work engagement in the public sector. Only minimal emphasis has been placed on organizational intervention compared to the other factors. This study also found that most literature addressed a single or a few themes of work engagement antecedents instead of a comprehensive work engagement model comprising all related aspects. This systematic review ends with directions for future studies to aid future scholars.
Bayesian Methods and Confidence Intervals for Automatic Target Recognition of SAR Canonical Shapes

Abstract : This research develops a new Bayesian technique for the detection of scattering primitives in synthetic aperture radar (SAR) phase history data received from a sensor platform. The primary goal of this research is the estimation of size, position, and orientation parameters defined by the ? canonical? shape primitives of Jackson. Previous Bayesian methods for this problem have focused on the traditional maximum a posteriori (MAP) estimate based on the posterior density. A new concept, the probability mass interval, is developed. In this technique the posterior density is partitioned into intervals, which are then integrated to form a probability mass over that interval using the Gaussian quadrature numerical integration techniques. The posterior density is therefore discretized in such a way that the location of local peaks are preserved. A formal treatment is given to the effect of locally integrating the posterior density in the context of parameter estimation. It is shown that the operation of choosing the interval with the highest probability mass is equivalent to an optimum Bayesian estimator that places zero cost on a ? range? of parameters. The range is user-controlled, and is akin to the idea of parameter resolution. Additionally the peak-preserving property allows the user to begin with coarse intervals and ? zoom? in as they see fit. Associated with these estimates is a measure of quality called the credible interval (or credible set). The credible interval (set) is a region of parameter space where the ? true? parameter is located with a user-defined probability. Narrow credible intervals are associated with high-quality estimates while wide credible intervals are associated with poor estimates. The techniques are implemented in state-of-the-art graphics processor unit (GPU) hardware, which allows the numerical integration to be performed in a reasonable time. A typical estimator requires several hundred million computations and the GPU implementa
Are Smartwatches Actually Used for Exercise? Evidence from HBCU Students

ABSTRACT Background Literature shows a litany of health issues disproportionately impacting Black Americans, with physical inactivity as a major risk factor. Purpose This study seeks to understand the role of smartwatches in physical activity uptake and subsequent improvement in health outcomes for students at HBCUs (Historically Black Colleges & Universities). Methods We administered an electronic survey to undergraduate students (n = 215) about smartwatch ownership, features, competitions, fitness goals and accomplishments, exercise tracking, frequency of exercise, perceptions of weight, and student demographics. Results Smartwatch owners who were aware of features such as calorie counting were significantly more likely to exercise at the gym at least once per week. The majority recorded themselves running and competed with other smartwatch users in some fashion. Others were unaware of fitness tracking features. Overall, smartwatch users were not more likely to workout than non-users and were significantly more likely to see themselves as overweight. Discussion Many smartwatch users are unaware of exercise tracking features and not using the devices to become more physically active. Translation to Health Education Practice Motivations for purchasing smartwatches must be explored, and initiatives to showcase the technology’s fitness promotion potential and encourage competition between users could yield positive health impacts.
Identifying and understanding challenges to inform new approaches to improve vaccination rates: A qualitative study in Indonesia

Abstract Purpose This study aimed to identify and understand challenges to inform new strategies to increase the COVID‐19 vaccination rate according to involved vaccinators' perspectives in Belitung, Indonesia. Design A qualitative descriptive study design was used. Methods Online interviews and chatting were done among 11 vaccinators for data collection between August 2021 and January 2022. Data were analyzed using a content analysis model. Findings Four main themes emerged, including (1) communication strategies (evidence‐based, electronic‐based, and culturally based communication), (2) cross‐sectoral strategies (collaboration with police, religious leaders, customary leaders, heads of village divisions, and non‐governmental organizations), (3) “picking‐up the ball” system (home visits for elderly and people with disability and school visits for children), and (4) setting‐up priorities (between mandatory vaccines and boosters). Conclusion Despite making vaccination mandatory, the roles of communication, cross‐sectoral innovations, “picking‐up the ball” system, and priority setting may have useful potential to improve vaccination rates. Clinical Relevance The findings may serve as an input to overcome challenges and accelerate the vaccination coverage in Indonesia and beyond. However, further research is needed.
Board characteristics and earnings management. Does firm size matter?

Abstract The purpose of this paper is to extend the existing literature by empirically examining the effect of board characteristics on earnings management (EM) from a developing region perspective. The study further adds literature by examining whether firm size moderates the relationship between board characteristics and EM. This study employs data drawn from 88 listed firms in the East African Community (EAC) for the period between 2011 and 2020. The study used the system generalized method of moments (SGMM) estimation model to take care of potential endogeneity and reverse causality. The findings revealed a positive and significant relationship between board size and EM. The findings further indicated that board independence, board gender diversity, and board financial expertise had a negative and significant effect on EM. In addition, the findings confirmed that firm size moderated the relationship between board size, board independence, board gender diversity, and EM. The insights of this study may provide useful information for shareholders and regulators in evaluating board attributes that are effective in mitigating earnings management practices from a developing region. Further, board effectiveness in deterring EM should be evaluated with regard to firm size. Just a few empirical studies have examined the relationship between board characteristics and EM in developing regions. Thus, this study contributes to the existing literature by empirically examining the topic in the EAC. Further, the study fills the existing gap in literature by examining whether firm size moderates the relationship between board characteristics and EM.
On an inverse scattering problem with an energy-dependent potential

The inverse scattering problem is considered for the radial s-wave Schrodinger equation with the energy-dependent potential V+ (E, x) = U (x) + 2 l’E Q (x), in the case of real potential U (x) and Q (x), when there is no bound state. To each element (U (x), Q (.r)) of a large class C’ of pairs of potentials is associated a function S+ (k) (k E R) called the « characteristic function " : : S+(~-)(~0) represents the scattering " matrix " and S+ (k) (k 0) plays the role of a parameter in the solution of the inverse problem. It is proved that there exists at most one pair (U (x), Q (r)) in (5’ which admits a given function S+ (k) (k E R) as its characteristic function, and, under very general assumptions on S+ (k) R), this pair is explicity constructed. The method of solution used generalizes the one given by Marchenko in the case Q (x) = 0. The results obtained also allow us to solve an inverse scattering problem associated with the radial s-wave Klein-Gordon equation of zero mass with a static potential in this case the characteristic function S+ (k) (k E R) for k ~ 0 represents the scattering " matrix " for a particle and for k ~ 0 represents the scattering " matrix " for the correspondent antiparticle -.

Gender Heterogeneity and Politics in Decision-Making About Green Public Procurement in the Czech Republic

Green public procurement (GPP) is a widely recognized public policy tool that has attracted considerable scholarly research. However, much of this research has paid little attention to the nature of discretionary decision-making on the part of bureaucrats and local politicians; nor has it recognized that a crucial determinant of the implementation of GPP is the extent to which women hold administrative and political positions. While GPP tends to be discussed as a tool for promoting gender equality, we draw on feminist insights to argue that doing so may be a tool for enhancing the uptake and implementation of GPP. Utilizing the data from a large-N survey among local politicians and upper-echelon bureaucrats in the Czech Republic, we develop a path analysis model exploring the influence of gender on their decision-making. The results give credence to our overall argument that women are more likely to promote GPP. This argument not only breaks new ground by revealing the gendered nature of GPP but also generates straightforward policy implications.
Switched LC Network-Based Multi-Stage Ultra Gain DC-DC Converter

A multi-stage active switched inductor-capacitor network (SLCN)-based high gain DC-DC converter structure with a single switch is proposed in this paper. The idea of utilizing multiple number of SLCN networks to achieve an ultra-voltage gain is proposed. The achievement of ultra-gain helps to operate the converter at lower duty ratio. Hence, a reduction of conduction loss, improvement in efficiency and elimination of core saturation are attained in the proposed bi-quadratic converter compared to the conventional converters. The performance of a biquadratic boost converter which is formulated from the n-stage SLCN converter for n=2, is analyzed. To reduce the effect of parasitic elements of the semiconductor devices, the SiC-based devices are selected. The small-signal model of the biquadratic converter is derived, and a PI controller is designed to regulate the output voltage. The designed controller is implemented using XSG platform. Experimental waveforms for 650 V output voltage, 500 W output power and 50 kHz switching frequency are presented. The performance of the proposed converter with similar recently reported topologies is compared. Simulation results of the bi-quadratic converter interfaced solar PV panel with P&O algorithm are presented to assess the feasibility of the proposed converter in solar PV application.
A note on shortest paths in the plane subject to a constraint on the derivative of the curvature

We consider the class of C 2 , piecewise C 3 , planar paths joining two given conngurations (position, orientation, and curvature) X 0 and X f , and along which the derivative of the curvature (with respect to the arc length) remains bounded. We admit an innnite (countable) number of pieces, as long as the switching points do not accumulate more than a nite number of times. For generic X 0 and X f , we prove that the path of minimal length satisfying the constraint is such that : either it contains no line segment, or it contains innnitely many arcs of clothoid. As a consequence, the number of C 3 arcs involved in a shortest path may not be uniformly bounded with respect to X 0 and X f. the plane. Note sur les plus courts chemins dans le plan soumis a une contrainte sur la d eriv ee de la courbure R esum e : On consid ere la classe des chemins C 2 dans le plan, C 3 par mor-ceaux, joignant deux conngurations donn ees (position, tangente et courbure) X 0 et X f , le long desquels la d eriv ee de la courbure (par rapport a l'abs-cisse curviligne) reste born ee. On admet un nombre innni (d enombrable) de morceaux, mais seulement un nombre ni de points d'accumulations pour les points de commutations. Pour des X 0 et X f g en eriques, on prouve que le plus court chemin satisfaisant la contrainte est tel que : soit il ne contient pas de segment de droite, soit il contient aussi un nombre innni d'arcs de clothoide. En cons equence, le nombre de morceaux de classe C 3 constituant un plus court chemin n'est pas uniform ement born e par rapport a X 0 et X f. Mots-cl e : planiication de trajectoires, commande optimale, plus courts chemins contraints dans le plan.
