Large-scale Machine Learning over Graphs

Graphs are ubiquitous in statistical modeling and a broad range of machine learning applications. Examples are social networks, natural language dependency structures, latent interrelationships among tasks, and neural network topologies. Despite their versatility in representing structured data, how to fuse the information from heterogeneous and/or dynamically evolving graphs poses a grand challenge to existing machine learning theory and optimization algorithms. Furthermore, efficient graph topology optimization is another important but unsolved problem which entails searching over a combinatorially large discrete space. In this thesis, we address these open challenges in several complementary aspects: In §1 we focus on a novel framework for fusing multiple heterogeneous graphs into a single homogeneous graph, on which learning tasks can be conveniently carried out in a principled manner. We also propose a new approach to impose analogical structures among heterogeneous nodes, which offers a theoretical unification of several representative models along with improved generalization. In §2 we focus on graph induction problems in the context of graph-based semisupervised learning. We start with a nonparametric method that is able to recover the optimal latent label diffusion pattern over the graph, and then generalize label diffusion processes as graph convolution operations whose filter weights are induced from data residing on the non-Euclidean manifold. In §3 we extend the scope of our modeling from static graphs to dynamic graphs. Specifically, we develop an online algorithm for multi-task learning with provable sublinear regret bound, where a latent graph of task interdependencies is dynamically inferred on-the-fly. We also look at time-series forecasting tasks, showing that the explicitly modeling of the graph dependencies among temporally evolving variables can improve the prediction accuracy. In §4 we formulate neural architecture search as a graph topology optimization problem. We present a simple yet efficient evolutionary algorithm that automatically identifies high-performing architectures based on a novel hierarchical representation scheme, where smaller operations are automatically discovered and reused as building blocks to form larger ones. The learned architecture achieves highly-competitive performance on ImageNet against the state-of-the-art, outperforming a large number of modern convolutional neural networks that were designed by hand.

NURSING PRACTICES IN CHILD CARE CONSULTATION IN THE ESTRATÉGIA SAÚDE DA FAMÍLIA

Objective: to analyze the care actions performed by nurses during child care consultations. Method: an observational, quantitative study with 31 nurses who performed child care consultations in the Estratégia Saúde da Família of a municipality of Paraíba (Brazil). Three randomized consultations were performed by each participating nurse, totaling 93 consultations between March and July 2016, through a previously structured checklist based on the guidelines of national child health care policies containing the care actions that should be implemented by nurses. The analysis was made through descriptive statistics and chi-square test, with a significance level of 5% and cluster analysis. Results: the most common dimensions of care performed were the evaluation of immunization and iron and vitamin A supplementation; anamnesis, welcoming, physical examination/neuropsychomotor development and health education were the actions least performed by the nurses. Conclusion: nursing care in child care consultation falls short of what is established by the child health care guidelines. Continuing education interventions to qualify nurses for comprehensive child care can overcome these shortcomings. DESCRIPTORS: Nursing. Child care. Child health. Primary health care.

CEO ’ s compensation and risk taking in UK firms

Prior empirical evidence on executive compensation and risk taking remained inconclusive. Most of these researches failed to adequately consider the endogenous relationship between compensation and risk. Furthermore, most studies focused on the US non-financial firm perhaps because US CEOs have received the highest level of compensation but lately the trends has shifted to other countries including the UK as well. I investigate whether higher executive compensation is related to greater riskier corporate decision in UK firms incorporating an additional measure of compensation referred to as Total wealth. CEO’s total wealth represents the accumulated equity linked compensation, which had already been received by CEOs over the years in the firm; this variable has not be considered due to unavailability of data. It is important to measure total wealth because executives will have greater incentive to ensure that the value of their accumulated equity earnings (total wealth) over time goes up and could therefore take more risk. I used panel data to control for unobservable heterogeneity in contracting environment of firms, and fixed effect two stage least square regressions to deal with endogeneity. I examine the relationship using six measure of compensation and two instruments (CEO age and CEO experience). The sample include both financial and non-financial firms over the period 1999 to 2017 analysed separately. Results support my hypothesis of positive and increasing relationship between all forms of compensation including total wealth and riskier corporate decisions (leverage and R&D) in both financial and non-financial firm. In addition, the level of pay measured by the proportion of each forms of compensation in total compensation matters as higher equity and higher salary reduces risk taking in non-financial firms and financial firms respectively.
Auswirkungen eines 6-monatigen Power Plate-Trainings auf die Hüftknochendichte, Muskelkraft und Haltungskontrolle bei Frauen im postmenopausalen Alter: Eine kontrollierte und randomisierte Pilotstudie

High-frequency mechanical strain seems to stimulate bone strength in animals. In this randomized controlled trial, hip BMD was measured in postmenopausal women after a 24-week whole body vibration (WBV) training program. Vibration training significantly increased BMD of the hip. These findings suggest that WBV training might be useful in the prevention of osteoporosis. Introduction: High-frequency mechanical strain has been shown to stimulate bone strength in different animal models. However, the effects of vibration exercise on the human skeleton have rarely been studied. Particularly in postmenopausal women—who are most at risk of developing osteoporosis—randomized controlled data on the safety and efficacy of vibration loading are lacking. The aim of this randomized controlled trial was to assess the musculoskeletal effects of high-frequency loading by means of whole body vibration (WBV) in postmenopausal women. Materials and Methods: Seventy volunteers (age, 58–74 years) were randomly assigned to a whole body vibration training group (WBV, n 25), a resistance training group (RES, n 22), or a control group (CON, n 23). The WBV group and the RES group trained three times weekly for 24 weeks. The WBV group performed static and dynamic knee-extensor exercises on a vibration platform (35–40 Hz, 2.28–5.09g), which mechanically loaded the bone and evoked reflexive muscle contractions. The RES group trained knee extensors by dynamic leg press and leg extension exercises, increasing from low (20 RM) to high (8 RM) resistance. The CON group did not participate in any training. Hip bone density was measured using DXA at baseline and after the 6-month intervention. Isometric and dynamic strength were measured by means of a motor-driven dynamometer. Data were analyzed by means of repeated measures ANOVA. Results: No vibration-related side effects were observed. Vibration training improved isometric and dynamic muscle strength ( 15% and 16%, respectively; p 0.01) and also significantly increased BMD of the hip ( 0.93%, p 0.05). No changes in hip BMD were observed in women participating in resistance training or age-matched controls ( 0.60% and 0.62%, respectively; not significant). Serum markers of bone turnover did not change in any of the groups. Conclusion: These findings suggest that WBV training may be a feasible and effective way to modify wellrecognized risk factors for falls and fractures in older women and support the need for further human studies.

Survival Estimates for Two Hawaiian Honeycreepers

Most Hawaiian forest birds are endangered by habitat loss and degradation, predation by introduced mammals, and introduced diseases, but species recovery planning has been hampered by lack of demographic information, such as annual survival rates. To address this knowledge gap, we analyzed mark-recapture data using the program MARK to estimate apparent survival in the endangered Maui parrotbill (Pseudonestor xanthophrys) and Maui ‘alauahio (Paroreomyza montana). Annual survival estimates were high in adult Maui parrotbills (0.84 ± 0.04) and Maui ‘alauahio (0.78 ± 0.15). Survival was lower in hatch-year parrotbills (0.76 ± 0.09) and hatch-year ‘alauahio (0.64 ± 0.13), and survival of ‘alauahio also varied among years (0.51 ± 0.18 to 0.95 ± 0.06 in adults). These results provide important baseline data for two little-known species of honey-creepers and, together with ongoing nest success and productivity studies, will enable assessment of population trends and inform management decisions. Mark-recapture methods are a useful tool for monitoring populations of rare and cryptic species that are difficult to monitor using traditional survey methods.
Inhibition Activity of Curcumin-Loaded Sterically Stabilized Micelles and Its Up-Regulator Effect on Enhancement of Cytotoxicity of a New Nano-Pirarubicin Formulation in the Treatment of Breast Cancer

This study aims to investigate the effects of co-administration of nano-Curcumin on anticancer effect of nano-Pirarubicin considering the fact that the clinical use of Pirarubicin and other anthracyclines has been limited by development of multidrug resistance (MDR) and based on previous data which have shown that Curcumin can down-regulate MDR proteins and suppress the activity of Nuclear factor-kappa B (NF-κB) a protein involved in chemoresistance. Nano micellar formulations of both Curcumin and Pirarubicin were separately synthesized using 1,2-Distearoyl-sn-glycero-3-phosphoethanolamine-N-methoxy-[poly(ethylene glycol); PEG MW 2,000] (DSPE-PEG2000). The produced sterically stabilized micelles (SSM) are very well known drug delivery systems in terms of their enhanced efficacy and good toxicity profile. We measured the differences of NF-κB levels in two different situations: when Pirarubicin is used alone and when it is co-administered with Curcumin. This study showed that co-administration of SSM-Curcumin (CSSM) and SSM-Pirarubicin (PSSM) with size of 12.81 nm enhances the efficacy of Pirarubicin by suppressing P65, an NF-κB subunit. Furthermore, we showed that SSM is able to successfully enhance water solubility and therapeutic stability of curcumin for using as a complementary agent.
From Heterogeneity to Concentration: Latino Immigrant Neighborhoods and Collective Efficacy Perceptions in Los Angeles and Chicago

Abstract:Latino immigrant presence in urban neighborhoods has been linked with reduced neighborhood cohesion in social disorganization–based ethnic heterogeneity hypotheses and enhanced cohesion in immigration revitalization approaches. Using the 2000–2002 Los Angeles Family and Neighborhood Survey and the 1994–1995 Project on Human Development in Chicago Neighborhoods Community Survey, we explore the association between Latino immigrant concentration and both levels of, and agreement about, neighborhood collective efficacy. Findings from multilevel models with heteroskedastic variance indicate that Latino immigrant concentration exhibits a nonlinear association with collective efficacy. At low levels, increases in Latino immigrant concentration diminish collective efficacy, consistent with a heterogeneity hypothesis. The negative association between Latino immigrant concentration and collective efficacy declines in magnitude as immigrant concentration increases and, particularly in LA, becomes positive beyond a threshold, consistent with an immigration revitalization effect. We also find an inverse nonlinear pattern of association with the variance of collective efficacy. At low levels, increasing Latino immigrant concentration increases the variance of collective efficacy (reflecting more disagreement), but beyond a threshold, this association becomes negative (reflecting increasing agreement). This pattern is observed in both LA and Chicago. The prevalence of social interaction and reciprocated exchange within neighborhoods explains a modest proportion of the Latino immigrant concentration effect on mean levels of collective efficacy in Chicago, but does little to explain effects on the mean in LA or effects on the variance in either LA or Chicago. These findings offer insight into the complex role Latino immigrant presence plays in shaping neighborhood social climate.
11-28-2018 Sharing Leadership through Digital Collaborative Objects

This paper contributes to the understanding of the role of collaborative tools and objects in the emergence and support of shared leadership, which has been associated with positive team dynamics and innovative outcomes. We draw on ideas from the recent discourse on viewing leadership as a practice that involves human actors and material or technological tools to provide the first analysis of the features of collaborative tools that can support shared leadership. We present our early findings and insights from a multiple case study of ten innovation teams in their interaction with a collaborative tool that is particularly designed for coordination. We suggest that collaborative tools can contribute to shared leadership through two facilitating features: shared problem space and shared visualisation. Through our findings, we highlight the role of collaborative tools in supporting teams in sharing leadership for the purpose of joint innovation.
In Situ FTIR Observations on NaCl-H 2 OD 2 O Fluids at Temperatures up to 850 ° C Using Hydrothermal Diamond Anivl Cell

NaCl–H2O is the main composition of the earth crust and mantle fluids. Aqueous fluids play a fundamental role in the geochemical evolution of the earth. But, knowledge for molecular nature of such fluids at temperatures approaching and exceeding the critical temperature of water, however, is more limited, thus may not accurately understand the behaviors of the fluids in the depths and their fundamental role in the geochemical evolution of the earth. Recently, many high temperature and pressure experiments combined with theoretical prediction (involving molecule dynamic calculations) indicated that given the huge range of P-T-x regimes in crust and mantle, aqueous fluids at high temperatures and pressures are strongly variable in molecular structure, phase transition, and exhibit specific physical and chemical properties. Previously, most investigators focus on high pressure water, i.e., ice. Water and aqueous solutions were in situ examined using diamond anvil cell (DAC) at super-high pressure and room temperature, using XRD, FT-IR, and Raman spectrometers, with synchrotron radiation light source (Aoki et al., 1996; Goncharov et al., 1999). Recently, in situ high pressure temperature Raman spectroscopy and synchrotron x-ray diffraction have been used to examine the phase diagram of H2O(Lin et al., 2005). But a few experiments using DAC on water and NaCl-H2O connected with FT-IR spectrometer are performed at high temperatures and very high pressures. We use hydrothermal diamond anvil cell connected with FT-IR spectrometric microscope to examine phase transitions and molecule structure of aqueous solutions at high temperatures and pressures.
Letter to the Editor

The research of El-Zein et al. (El-Zein et al., 2005, 2006) suggesting increased risk of cytogenetic abnormalities (Goldstein, 2010; Ponsa et al., 2009) stimulated a series of activities beginning in 2005 and extending to the present, within the US DHHS (United States Department of Health and Human Services) because of the common use of this drug in children and adolescents and because this was an unexpected result (NTP-CERHR, 2005). This response included scientists from NIH (NICHD, NIEHS, NIMH, and NINDS) as well as scientists from FDA. The activity included a visit to the laboratory in Texas which conducted the cytogenetic assays (Jacobson-Kram et al., 2008), studies in non-human primates (Morris et al., 2009; Rodriguez et al., 2010), rodents (Manjanatha et al., 2008, 2009) and children (Witt et al., 2008). All of these studies have been reassuring with respect to cytogenetic risk. Rodent studies, conducted at doses producing concentrations greater than human blood concentrations for 6 months, demonstrated toxicity however no increase in cytogenetic endpoints including; micronuclei or lymphocyte Hprt mutations was observed (Manjanatha et al., 2008). Subsequent studies evaluating the mechanism by which liver tumors were induced in mice observed no change in liver cll mutations, lymphocyte micronuclei or Hprt mutations suggesting that rodent liver tumors are produced by a non-genotoxic mechanism (Manjanatha et al., 2009). Non human primate studies were conducted in juvenile rhesus for 20 months using doses producing concentrations similar to those observed in humans (Morris et al., 2009). No significant increases in the frequencies of MN-RETs, HPRT mutants, or chromosome aberrations were detected in the treated animals compared to the control animals over the 20-month treatment. Human studies were similar to those conducted by El-Zein; children diagnosed with ADHD were studied before and at 3 months after initiating initial treatment with methylphenidate or amphetamine (Witt et al., 2008). No changes were observed in chromosome aberrations, micronuclei or sister chromatid exchange, the same cytogenetic markers studied by El-Zein et al. While these DHHS initiated studies are reassuring, and consistent with prior research (NTP-CERHR, 2005), a substantial body of work has also been published by other investigators suggesting that methylphenidate does not produce genetic toxicity or increased cancer risk (Andreazza et al., 2007; Dobrovolsky et al., 2010; Oestreicher et al., 2007; Ponsa et al., 2009; Stopper, Walitza, Warnke, & Gerlach, 2008; Suter, Martus, & Elhajouji, 2006; Teo et al., 2003; Tucker et al., 2009; Walitza et al., 2007, 2009, 2010; Witt et al., 2010; Zito & Safer 2007).
DEVELOPMENT OF AN ALTERNATIVE SYSTEM FOR THAI INSTRUCTORS USING ENGLISH AS A MEDIUM OF INSTRUCTION

The English for Integrated Studies (EIS) program has been accepted as an innovative practice to be utilized for Thai non-English speaking teachers (NESTs) using English as a medium of instruction (EMI) in the Thai basic education curriculum to increase the accessibility of the English program (EP) of the ministry of education to all students. The purpose of this research is to explore the problems and issues of the schools using EMI, to develop an alternative system of using EMI for NESTs and finally to determine the effectiveness of the alternative system. The Phenomenology theory approach of qualitative research was used as strategic research with the purpose of selecting key informants in 266 schools who provide and teach EP and/or EIS in the secondary and vocational education levels throughout Thailand. The results of the study show that the benefits and advantages from providing EIS program strongly supports solving the permanent problems in providing EP, such as reliance on outsourcing and
Genetic Improvement Of Litter Size In Rabbits

Breeding programs in rabbits are more recent than those developed in other species. In France and Spain breeding programs began in the seventies (Matheron (1982) and Estany et al. (1989)) and since then a large number of reviews have discussed the advances made in this area (Rouvier (1980); Baselga et al. (1982); Matheron (1982); Matheron and Poujardieu (1984); Rochambeau (1988); Blasco (1996); Garreau et al. (2004); Baselga (2004); Khalil and Al-Saef (2008)).
Match Demands, Anthropometric Characteristics, and Physical Qualities of Female Rugby Sevens Athletes: A Systematic Review.

Sella, FS, McMaster, DT, Beaven, CM, Gill, ND, and Hébert-Losier, K. Match demands, anthropometric characteristics, and physical qualities of female rugby sevens athletes: A systematic review. J Strength Cond Res XX(X): 000-000, 2019-Since the inclusion of rugby sevens in the 2016 Olympic Games, the popularity of women's rugby sevens has grown rapidly worldwide. This systematic review aimed to summarize the scientific literature addressing the match demands, anthropometric characteristics, and physical qualities of female rugby sevens athletes and to highlight differences between competition levels and playing positions. Four electronic databases were searched, as were the reference lists and key journals. Hedges' g effect sizes with 95% confidence intervals were calculated to evaluate differences between elite and nonelite athletes, and backs and forwards. Twenty-seven studies met inclusion criteria and scored 68 ± 13% upon quality assessment. Comparisons between groups were restricted to variables where data were available. Greater running demands and intensities, number of sprints and accelerations, but lower physiological responses characterized international matches compared with nationals. At international level, backs demonstrated greater running demands and intensities, number of sprints, and physiological responses than forwards. Elite athletes were leaner, taller, and displayed superior physical qualities (e.g., maximal speed, power, upper-body strength, and aerobic capacity) compared with nonelite athletes. At elite level, forwards were heavier and displayed greater upper-body strength, whereas backs showed greater acceleration and maximal speed abilities. The specific match demands and physical requirements of female rugby sevens athletes competing at different playing levels and playing positions must be considered for developing effective training programs.
