Submanifold density estimation

Kernel density estimation is the most widely-used practical method for accurate nonparametric density estimation. However, long-standing worst-case theoretical results showing that its performance worsens exponentially with the dimension of the data have quashed its application to modern high-dimensional datasets for decades. In practice, it has been recognized that often such data have a much lower-dimensional intrinsic structure. We propose a small modification to kernel density estimation for estimating probability density functions on Riemannian submanifolds of Euclidean space. Using ideas from Riemannian geometry, we prove the consistency of this modified estimator and show that the convergence rate is determined by the intrinsic dimension of the submanifold. We conclude with empirical results demonstrating the behavior predicted by our theory.
Burnout Among Sexual Minority Mental Health Practitioners: Investigating Correlates and Predictors

Burnout is a significant concern that results in negative outcomes for both mental health practitioners (MHPs; e.g. counselors, psychologists, social workers) and their clients. Viehl and Dispenza (2015) found that sexual-minority-identified MHPs reported higher rates of burnout when compared to heterosexual-identified MHPs. To continue understanding what factors contribute to burnout among sexual-minority-identified MHPs, we used Internet survey procedures to explore possible correlates and predictors of burnout among 84 sexual- minority-identified MHPs. MHPs were recruited and sampled from across the U.S. Perceptions of reasonable workload, perceptions of workplace heterosexism, perceptions of workplace support, and identity concealment were all explored in this study as specific factors that could lead to burnout. All of the aforementioned factors correlated with burnout, and to some degree, uniquely predicted burnout among the MHPs sampled for this study. Perceptions of workplace support also mediated the relationship between workplace heterosexism and burnout. The data supports the need for MHPs, MHP educators, and clinical supervisors to address the stigma related to sexual minority identity as a potential contributor to burnout, as well as ways to navigate this marginalized identity within the mental health field.
Will Improving My Marriage Improve My Sleep?

ABSTRACT An essential component to overall health and well-being is sleep. Likewise, being happily married is associated with better physical, mental, and emotional health. In the present study, we examined links between marital satisfaction (MS) and aspects of sleep quality (SQ) among married individuals (N = 88) aged 39 to 64 years. Data were collected at baseline and 6-month follow-up. Regression analyses showed that MS at baseline was positively associated with overall SQ and sleep disturbance frequency at baseline and was negatively associated with minutes to fall asleep at follow-up. Results suggested that participants with greater MS at baseline reported better overall SQ at baseline and falling asleep faster at follow-up. However, results varied when controlling for other relevant covariates (e.g., age, depression, pain). Additionally, a negative change in MS between baseline and follow-up was a positive predictor of sleep disturbance frequency at follow-up, suggesting that participants whose MS decreased over time were more likely to report more frequent sleep disturbances 6 months later. Findings indicate that MS is linked with various aspects of SQ in married, middle-aged adults. Clinical implications, limitations of the current study, and areas for future research are discussed.
Take a look at the bright side : effects of positive body exposure on visual attention in body dissatisfied women

Background: Body image disturbance is one of the main diagnostic criteria for eating disorders and is considered an important factor in the onset and maintenance of these disorders. Body dissatisfaction has been linked to dysfunctional selective visual attention towards one's body. In comparison to normal controls, individuals high on eating disorder symptoms showed a decreased attention to their own 'beautiful' body parts and an increased attention to their own 'ugly' body parts (Jansen, Nederkoorn & Mulkens, 2005). The present study was designed to 1) replicate this prior study and 2) examine whether dysfunctional viewing patterns can be changed by positive body exposure. This way we aim to contribute to bridging the gap between science and practice of body exposure, which is already being widely used in clinical practice despite the fact that we still know little about if en how this intervention might be effective. Method: 29 highly body dissatisfied women with a normal weight and 14 satisfied controls were exposed to pictures of their own body and control bodies. Eye movement registration was used to assess selective visual attention (cf. Jansen et al., 2005). Then, dissatisfied individuals were randomly assigned to a 5-session training condition (N=16) or a no treatment control group (N=13) and after the training they were assessed again. Results: We just finished the data-acquisition. Results and theoretical implications will be discussed during the conference. Discussion: These results will help to determine whether positive body exposure is effective in improving dysfunctional selective visual attention in body dissatisfied women.
Emotional labor, teacher burnout, and turnover intention in high-school physical education teaching

Grounded upon the conservation of resources theory, this study sought to examine the relationships between the three emotional labor strategies, teacher burnout, and turnover intention among physical education teachers. A total of 613 high-school physical education teachers from 47 states across the United States completed online questionnaires that measured the proposed variables. The goodness-of-fit statistics indicated that the structural model showed a reasonable fit, χ2(605) = 1391.26 = 2.30, p < 0.01; RMSEA = . 05; TLI = . 93; CFI = . 93. The results also revealed that teacher burnout was positively associated with surface acting and negatively associated with genuine expression. Further, teacher burnout was positively associated with turnover intention. Mediation analysis showed that teacher burnout fully mediated the trajectory from emotional labor strategies to turnover intention. The results highlight the impact of emotional labor on physical education teachers’ well-being and intention to leave the teaching profession.
Prognostic Value of Pentraxin-3 Level in Patients with STEMI and Its Relationship with Heart Failure and Markers of Oxidative Stress

Objective. Pentraxin-3 (PTX3) appears to have a cardioprotective effect through a positive influence against postreperfusion damage. This study assesses the prognostic value of PTX3 level and its relationship with clinical parameters and markers of oxidative stress and nitric oxide metabolism in patients with ST-elevation myocardial infarction (STEMI). Methods. Plasma/serum levels of several biomarkers of inflammation and oxidative stress and nitrite/nitrate were assessed upon admission and 24 h after STEMI onset in patients treated by primary percutaneous coronary intervention. Results. ROC analysis showed that plasma PTX3 at 24 h was a strong predictor of 30-day and 1-year mortality and independent predictor of combined end-point of left ventricle dysfunction or mortality in 1 year. The inflammatory response expressed by PTX3 had a significant relationship with age, heart failure, infarct size, impaired flow in the infarct-related artery, and renal function and positively correlated with neopterin, TNF-α, 8-hydroxy-2′-deoxyguanosine, and nitrite/nitrate. Conclusions. Plasma PTX3 at 24 h after STEMI onset is a strong predictor of 30-day and 1-year mortality. PTX3 as a single biomarker is comparable with currently used scoring systems (TIMI or GRACE) or B-type natriuretic peptide. PTX3 is also an independent predictor of combined end-point of left ventricle dysfunction or mortality in 1 year.
Implementation of linear‐scaling plane wave density functional theory on parallel computers

We describe the algorithms we have developed for linear‐scaling plane wave density functional calculations on parallel computers as implemented in the onetep program. We outline how onetep achieves plane wave accuracy with a computational cost which increases only linearly with the number of atoms by optimising directly the single‐particle density matrix expressed in a psinc basis set. We describe in detail the novel algorithms we have developed for computing with the psinc basis set the quantities needed in the evaluation and optimisation of the total energy within our approach. For our parallel computations we use the general Message Passing Interface (MPI) library of subroutines to exchange data between processors. Accordingly, we have developed efficient schemes for distributing data and computational load to processors in a balanced manner. We describe these schemes in detail and in relation to our algorithms for computations with a psinc basis. Results of tests on different materials show that onetep is an efficient parallel code that should be able to take advantage of a wide range of parallel computer architectures.

Automated Detection of Test Fixture Strategies and Smells

Designing automated tests is a challenging task. One important concern is how to design test fixtures, i.e. code that initializes and configures the system under test so that it is in an appropriate state for running particular automated tests. Test designers may have to choose between writing in-line fixture code for each test or refactor fixture code so that it can be reused for other tests. Deciding on which approach to use is a balancing act, often trading off maintenance overhead with slow test execution. Additionally, over time, test code quality can erode and test smells can develop, such as the occurrence of overly general fixtures, obscure in-line code and dead fields. In this paper, we show that test smells related to fixture set-up occur in industrial projects. We present a static analysis technique to identify fixture related test smells. We implemented this test analysis technique in a tool, called TestHound, which provides reports on test smells and recommendations for refactoring the smelly test code. We evaluate the tool through three industrial case studies and show that developers find that the tool helps them to understand, reflect on and adjust test code.
Warmth, Competence, and Willingness to Donate: How Perceptions of Partner Organizations Affect Support of Corporate Social Responsibility Initiatives in Professional Sport

To enact corporate social responsibility (CSR) initiatives, sport organizations often partner with organizations in different sectors, including public, private, and nonprofit. These partnerships provide teams and leagues with needed resources to effectively execute social initiatives. Little is known, however, about sport organizations’ partnership portfolios and the effectiveness of combining partnerships to improve cause outcomes. Using two experimental studies, we examine perceptions of partnership organizations in terms of warmth and competence, how these combined perceptions in a portfolio affect individuals’ willingness to donate to CSR initiatives, and whether portfolio perceptions can be improved by articulation. We find that perceptions of portfolio warmth and competence increased willingness to donate to sport organizations’ CSR initiatives through the serial mediation effects of cause fit and response efficacy in the structural equation model. Furthermore, we find that corporate competence articulation reduced the mediation effect of response efficacy in the structural relationship.
Proteomics as the Tool to Search for Lung Disease Markers in Bronchoalveolar Lavage

Most lung disorders are known to be associated to considerable modifications of surfactant composition. Numerous of these abnormalities have been exploited in the past to diagnose lung diseases, allowing proper treatment and follow-up. Diagnosis was then based on phospholipid content, surface tension and cytological features of the epithelial lining fluid (ELF), sampled by bronchoalveolar lavage (BAL) during fiberoscopic bronchoscopy. Today, it appears that the protein content of ELF displays a remarkably high complexity, not only due to the wide variety of the proteins it contains but also because of the great diversity of their cellular origins. The significance of the use of proteome analysis of BAL fluid for the search for new lung disease marker proteins and for their simultaneous display and analysis in patients suffering from lung disorders has been examined.
Playing Games: Listening to the Voices of Children to Tailor a Mindfulness Intervention

Abstract:This field report describes a community-based project that incorporates game playing to enhance an existing mindfulness-based stress reduction approach for children. The first phase of the project involved content analysis of children's diary recordings their experiences of participating in a mindfulness intervention. In the second phase, focus groups conducted with a group of these children guided the development of a game-playing script that could be used in delivery of a mindfulness program. Significant lessons are offered regarding incorporating game-playing into a mindfulness program that recognizes the voices of children and respects and values their experiences.
Saudi Science Teachers' Perceptions of Implementing Inquiry in Science Class

This study aims to measure science teachers’ perception about their students’ practices in science class, and to measure their model of inquiry teaching. The sample consisted of 127 middle school science teachers in Riyadh, Saudi Arabia, 65 males and 62 females, in the school year 2016/2017, and utilized a questionnaire with two parts, 11 items for their students’ practices, and 27 items related to model of inquiry teaching. The results showed that the general average of teacher’s assessment of their students’ practices in science class was "average", except for finding relevant literature was "low". Teachers' perceptions of their degree of practices of inquiry showed that all the three models "structured, guided, and open" rated as "average". In "Structured Inquiry", the means of males’ responses ranged between (3.60) and (2.61), while the females ranged between (3.92) and (3.02), indicating that both of them are practicing structured inquiry with a range from moderate to high practice. For the "Guided Inquiry" the means ranging between (3.52) and (2.97) for males, and (3.58) and (2.74) for females, indicating that the range from moderate to high practice. And for the perceptions of practicing "Open Inquiry" the means ranged between (3.38) and (2.42) for males, and (3.34) and (2.13) for females, indicating that they practice "Open Inquiry" between moderate and low practice. There were no statistically significant differences between male and female teachers’ perceptions for their students’ practices and of the degree to which they exercised all models of inquiry. Based on the findings, the researcher suggests a number of pedagogical implications.
Examining Science Educators’ Perspectives on Learning Progressions in a Climate Change Education Professional Development Program

ABSTRACT In the context of a weeklong summer professional development program focused on climate change education, we conducted a qualitative case study investigating how science educators’ understandings of learning progressions (LPs) informed their ideas about climate change teaching practice. Participants (N = 27) in the Climate Academy were middle school (n = 14), high school (n = 7), higher education (n = 2), and informal (n = 4) science educators from 2 Mid-Atlantic states in the United States. In cooperation with other Climate Academy facilitators, we engaged participants in a variety of professional learning activities, among which were exploring LPs and their potential utility for informing climate change teaching practice. During these activities with LPs, the science educators engaged with LPs on 2 constructs relevant to climate change: carbon cycling and sea level rise. We collected data in the forms of observational field notes and personal interviews to gain insight into participants’ perspectives on LPs and their potential utility for supporting instructional decision making related to climate change. Our analysis of the data indicated that participants related LPs to 4 key areas: advancing student understanding, assessing student understanding, instructional planning, and providing instructional supports. We found that our participants assimilated LP ideas into their preexisting views of teaching and learning, which could facilitate or hinder transformation in their instructional approaches. Implications apply directly to science educator professional development in climate change education and in general to professional development in science education that includes LPs as a focus.
Towards the optimal window for the 2MASS dipole

A comparison of the 2MASS flux dipole to the CMB dipole can serve as a method to constrain a combination of the cosmological parameter m and the luminosity bias of the 2MASS survey. For this constraint to be as tight as possible, it is n ecessary to maximize the correlation between the two dipoles. This can be achieved by optimizing the survey window through which the flux dipole is measured. Here we explicitly constru ct such a window for the 2MASS survey. The optimization in essence reduces to excluding from the calculation of the flux dipole galaxies brighter than some limiting magnitude Kmin of the near-infrared Ks band. This exclusion mitigates nonlinear effects and shot noise f rom small scales, which decorrelate the 2MASS dipole from the CMB dipole. Under the assumption of negligible shot noise we find that the optimal value of Kmin is about five. Inclusion of shot noise shifts the optimal Kmin to larger values. We present an analytical formula for shot noise for the 2MASS flux dipole, to be used in follow-up work with 2MASS data. The misalignment angle between the two dipoles is a sensitive measure of their correlation: the higher the correlation, the smaller the expectati on value of the angle. A minimum of the misalignment is thus a sign of the optimal gravity window. We model analytically the distribution function for the misalignment angle and show that the misalignment estimated by Maller et al. is consistent with the assumed underlying model (though it is greater than the expectation value). We predict with about 90% confidence that the misalignment will decrease if 2MASS galaxies brighter than Kmin = 5 mag are excluded from the calculation of the flux dipole. This prediction has been indirectly confirme d by the results of Erdo˘ gdu et al. The measured misalignment constitutes thus an alternative way of finding the optimal value of Kmin: the latter corresponds to a minimum of the former.
Object modeling by registration of multiple range images

The problem of creating a complete model of a physical object is studied. Although this may be possible using intensity images, the authors use range images which directly provide access to three-dimensional information. The first problem that needs to be solved is to find the transformation between the different views. Previous approaches have either assumed this transformation to be known (which is extremely difficult for a complete model) or computed it with feature matching (which is not accurate enough for integration. The authors propose an approach that works on range data directly and registers successive views with enough overlapping area to get an accurate transformation between views. This is performed by minimizing a functional that does not require point-to-point matches. Details are given of the registration method and modeling procedure, and they are illustrated on range images of complex objects. <<ETX>>
Optimal Pilot and Payload Power Control in Single-Cell Massive MIMO Systems

This paper considers the jointly optimal pilot and data power allocation in single-cell uplink massive multiple-input-multiple-output systems. Using the spectral efficiency (SE) as performance metric and setting a total energy budget per coherence interval, the power control is formulated as optimization problems for two different objective functions: the weighted minimum SE among the users and the weighted sum SE. A closed form solution for the optimal length of the pilot sequence is derived. The optimal power control policy for the former problem is found by solving a simple equation with a single variable. Utilizing the special structure arising from imperfect channel estimation, a convex reformulation is found to solve the latter problem to global optimality in polynomial time. The gain of the optimal joint power control is theoretically justified, and is proved to be large in the low-SNR regime. Simulation results also show the advantage of optimizing the power control over both pilot and data power, as compared to the cases of using full power and of only optimizing the data powers as done in previous work.
Gingival Enlargement Induced by Felodipine Resolves with a Conventional Periodontal Treatment and Drug Modification

We present a case of a 47-year-old male who suffered from GE around his lower anterior teeth as soon as he started treatment with Felodipine 400 mg. We show that oral hygiene measures, antibiotics, and conventional periodontal treatment (scaling and root planing SRP) were all not sufficient to resolve the drug induced GE, which will persist and/or recur provided that systemic effect of the offending medication is still present. The condition immediately resolved after switching to a different medication. The mechanism of GE is complex and not fully understood yet. It is mainly due to overexpression of a number of growth factors due to high concentrations of calcium ions (Ca2+). This affects fibroblasts proliferation and DNA synthesis and leads to a heavy chronic inflammatory cell infiltrate. Our case was managed according to the suggested protocols in previous case studies. The unique features in our case were the immediate onset of the adverse effect after starting the medication and the absence of any underlying medical condition apart from high blood pressure. Improving the oral hygiene together with SRP and cessation of the medication resolves drug induced GE.
Maternal BMI, IGF-I Levels, and Birth Weight in African American and White Infants

At birth, elevated IGF-I levels have been linked to birth weight extremes; high birth weight and low birth weight are risk factors for adult-onset chronic diseases including obesity, cardiovascular disease, and type 2 diabetes. We examined associations between plasma IGF-I levels and birth weight among infants born to African American and White obese and nonobese women. Prepregnancy weight and height were assessed among 251 pregnant women and anthropometric measurements of full term infants (≥37 weeks of gestation) were taken at birth. Circulating IGF-I was measured by ELISA in umbilical cord blood plasma. Linear regression models were utilized to examine associations between birth weight and high IGF-I, using the bottom two tertiles as referents. Compared with infants with lower IGF-I levels (≤3rd tertile), those with higher IGF-I levels (>3rd tertile) were 130 g heavier at birth, (β-coefficient = 230, se = 58.0, P = 0.0001), after adjusting for gender, race/ethnicity, gestational age, delivery route, maternal BMI and smoking. Stratified analyses suggested that these associations are more pronounced in infants born to African American women and women with BMI ≥30 kg/m2; the cross product term for IGF-I and maternal BMI was statistically significant (P ≤ 0.0004). Our findings suggest that the association between IGF-I levels and birth weight depends more on maternal obesity than African American race/ethnicity.
