Job Satisfaction, Organizational Commitment, and Contextual Performance: Examining Effects of Work Status and Emotional Intelligence among Private Club Staff Members

This study explored the effects of work status (part-time vs full-time) and emotional intelligence (high EIvs low EI-groups) on job satisfaction, organizational commitment, and contextual performance, using a sample of private club staff members (N = 136). Multivariate analysis of covariance (MANOVA) showed that there were no statistically significant differences between part-time and full-time staff members with regard to job satisfaction, organizational commitment, and contextual performance. On the other hand, multivariate effects for emotional intelligence and work status × emotional intelligence interaction were statistically significant, respectively. Practical implications for the private club industry are also provided in terms of hiring and training procedures.
BEHAVIOR OF BRAZILIAN COMMERCIAL RELATIONSHIP FOR HARDWOOD LUMBER EXPLAINED WITH GRAVITATIONAL EQUATION

The aim of this study was to explain the dynamics of Brazil’s hardwood lumber exports. The database containing information regarding the sales of hardwood lumber between 1997 and 2010, distance between Brazil and its hardwood lumber importers, a dummy variable indicating the contiguity, GDP and GDP per capita of the countries that bought hardwood lumber from Brazilian was analyzed. The fitted equation showed r=63.65% and all the variables were significant. This equation showed that countries with bigger economies import more Brazilian hardwood lumber than countries with small economies. Besides, the negative signal on the adjusted parameter associated with the distance shows that the imported quantity for the countries is inversely proportional to distance. The gravitation model explained Brazil’s sawn hardwood exports.
El programa ConRed, una práctica basada en la evidencia = The ConRed Program, an Evidence-based Practice

The incredible force with which ITCs have arrived in society and the consequent risks to children when dealing with the Internet and social networks make it necessary for the domain of virtual environments to be included in the school curriculum. However, the initiatives in this direction are limited and there is a lack of rigorously evaluated programs that might act as a basis for designing educational lines of action. The ConRed Program is based on the theory of normative social behavior and aims to reduce problems such as cyber-bullying and addiction to the Internet and refocus the misadjusted perception of information control in the social networks in order to promote their use in a more beneficial way. The ConRed Program has been evaluated using a quasi-experimental methodology, with an experimental group (N=595) and a quasi-control group (N=298) consisting of 893 students (45.9% girls) with an average age of 13.80 years (SD= 1.47). The reduction of problems in the experimental group and the lack of change in the control group is evidence of the program’s validity, and show that by working and collaborating with the whole educational community it is possible to improve the quality of the virtual and, therefore, the real life of adolescents. RESUMEN La vertiginosa incorporación de las TIC a la sociedad y los consecuentes riesgos a los que los menores se enfrentan en Internet y las redes sociales han dejado en evidencia la necesidad de incorporar en el currículum escolar el dominio de los entornos virtuales. En cambio, son escasas las iniciativas en esta dirección y más aún programas rigurosamente evaluados, de modo que sirvan de fundamento para el diseño de las líneas de acción educativa. El programa ConRed está basado en la teoría del comportamiento social normativo y persigue los objetivos de mejorar y reducir problemas como el cyberbullying, la dependencia a Internet y la desajustada percepción del control de la información en las redes sociales, para así potenciar el uso beneficioso de éstas. La evaluación del ConRed se ha desarrollado mediante una metodología cuasi experimental, con un grupo experimental (N=595) y uno cuasi-control (N=298). Del total de los 893 estudiantes, el 45,9% eran chicas y la edad media 13,80 años (DT=1,47). Los resultados positivos de reducción de problemas en el grupo experimental y la ausencia de cambio en el grupo control son muestra de su validez y demuestran que trabajando con toda la comunidad educativa y en colaboración con ella es posible mejorar la calidad de la vida virtual y, por tanto, real de los adolescentes.
Differentially Private Uniformly Most Powerful Tests for Binomial Data

We derive uniformly most powerful (UMP) tests for simple and one-sided hypotheses for a population proportion within the framework of Differential Privacy (DP), optimizing finite sample performance. We show that in general, DP hypothesis tests for exchangeable data can always be expressed as a function of the empirical distribution. Using this structure, we prove a `Neyman-Pearson lemma' for binomial data under DP, where the DP-UMP only depends on the sample sum. Our tests can also be stated as a post-processing of a random variable, whose distribution we coin "Truncated-Uniform-Laplace" (Tulap), a generalization of the Staircase and discrete Laplace distributions. Furthermore, we obtain exact p-values, which are easily computed in terms of the Tulap random variable. We show that our results also apply to distribution-free hypothesis tests for continuous data. Our simulation results demonstrate that our tests have exact type I error, and are more powerful than current techniques.
ON FLAT SUBMAPS OF MAPS OF NONPOSITIVE CURVATURE

We prove that for every r > 0 if a nonpositively curved (p, q)-map M contains no flat submaps of radius r, then the area ofM does not exceed Crn for some constant C. This strengthens a theorem of Ivanov and Schupp. We show that an infinite (p, q)-map which tessellates the plane is quasi-isometric to the Euclidean plane if and only if the map contains only finitely many nonflat vertices and faces. We also generalize Ivanov and Schupp’s result to a much larger class of maps, namely to maps with angle functions.
Intervention Strategies Promoting Academic Self-Efficacy in Prospective First-Generation College Students: A Literature Review

This literature review first identifies the challenges facing prospective first-generation college students (PFGCS) including a lack of academic preparation in high school, financial barriers created by lower socioeconomic status (SES), and a lack of family support due to unfamiliarity with higher education (Majer, 2009; Olive, 2008; Weiser & Riggio, 2010). Second, this literature review examines the positive correlation between increased academic self-efficacy (ASE) and academic achievement (Elias & Loomis, 2002; Robbins et al., 2004; Zajacova, Lynch, & Espenshade, 2005). Third, this literature review provides a conceptual framework for PFGCS intervention program development based on four strategies found to influence ASE: enactive experiences, vicarious experiences, verbal persuasion, and physiological and affective states (Gandara & Bail, 2001; Habel, 2009; Robbins et al., 2004; Zimmerman, 2000). Fourth, the literature review provides implications including the proposed use of an ASE framework for existing intervention program assessment, a recommendation for the use of an ASE framework to guide high school educator and program administrator activities, and the proposed use of an ASE framework for school counselor planning activities serving the PFGCS population.
Effect of Glycemic Control on Plasma Oxidized Low Density Lipoprotein Levels in Diabetics

Objective: Increased low-density lipoprotein (LDL) glycation in diabetics could facilitate LDL oxidation, which is proatherogenic. I studied plasma oxidized LDL (OxLDL) levels in diabetics and non-diabetics, their relation to glycemic control, and their circadian variations. Methods: OxLDL in diabetics (n=32) and in non-diabetics without coronary artery diseases (n=20) were compared. OxLDL in diabetics (n=24) was measured on Days 2, 3, 4, 8 and the last day of hospitalization. Circadian variation in OxLDL in diabetics (n=18) was also examined. Glycemic control was implemented during hospitalization. Patients: The diabetics were divided into two groups; moderately-controlled (MC) group (HbA1c < 9.0% at admission, n = 15) and poorly-controlled (PC) group (HbA1c ≧ 9.0% at admission, n = 9). Results： In the MC group, OxLDL decreased by 20.8% after glycemic control (p = 0.0139), but not in the PC group. OxLDL is correlated with LDL on Days 3, 4, 8 (r = 0.837, 0.864, 0.801, respectively), TG on Day 8(r = 0.932), and Lp(a) at discharge (r = 0.871). In the PC group, OxLDL was 15.8% higher on the average in the daytime than at night (p = 0.0024). Conclusion： Plasma OxLDL is decreased by glycemic control, particularly in moderately glycemic controlled patients. OxLDL has a circadian variation, particularly in poorly glycemic controlled patients. Long-term glycemic control could reduce the progression of atherosclerosis, by reducing OxLDL levels.
Behaviour of fiber reinforced concrete beams with spliced tension steel reinforcement

The aim of the current work is to describe the flexural and bond behaviour of simply supported concrete beams with tension reinforcement spliced at mid-span. The parameters included in the study were the type of the concrete, the splice length and the configuration of the hooked splice. Fifteen beams were cast using an ordinary concrete mix and two fiber reinforced concrete mixes incorporating steel and polypropylene fibers. Each concrete mix was used to cast five beams with continuous, spliced and hooked spliced tension steel bars. A test beam was reinforced on the tension side with two 12-mm bars with a splice length of 20 and 40 times the bar diameter. The hooked bars were spliced along 20 times the bar diameter and provided with 45-degree and 90-degree hooks. The test results in terms of cracking and ultimate loads, cracking patterns, ductility, and failure modes are reported. The results demonstrated the consequences due to short splices and the improvement in the structural behaviour due to the use of hooks and the confinement provided by the steel and polypropylene fibers. Keywords: bond; splice; hook; fiber reinforced concrete; steel fibers, polypropylene fibers.
Effect of tissue decomposition on stable isotope signatures of striped dolphins Stenella coeruleoalba and loggerhead sea turtles Caretta caretta

Marine mammals and turtles are often studied using the carcasses of stranded dead individuals. Since decomposition processes might modify the stable isotope ratios of tissues, the present study tested the effects of decomposition on carbon (δ 13 C) and nitrogen (δ 15 N) stable iso- tope ratios in 2 tissue types of striped dolphin Stenella coeruleoalba and loggerhead sea turtle Caretta caretta. Decomposing carcasses of 3 dolphins and 3 turtles were sampled for muscle and skin for 62 d. Following lipid extraction, samples were analysed regularly using a continuous flow- isotope ratio mass spectrometer. Samples reached decomposition stage CC4 after 62 d at ambient temperature, but no statistical change in δ 13 C or δ 15 N was observed over that period for either tis- sue or species. These results imply that muscle and skin samples from carcasses decomposing out of water at stage CC4 or lower can be used as reliable material for stable isotope analysis in these 2 species, and probably in other marine mammal and marine turtle species. The effects of decom- position on the stability of stable isotope ratios in other tissues, in carcasses at stage CC5, or in car- casses decomposing underwater require further study.
Accuracy of Medicaid reporting in the ACS: Preliminary results from linked data

The “Medicaid undercount” refers to the discrepancy between administrative counts of Medicaid enrollment and estimates from survey data. Nearly all state and federal surveys estimate fewer Medicaid enrollees than is described by enrollment records. In the 2005 Current Population Survey (CPS) 40.8% of people known to have Medicaid from administrative records were not reported as having Medicaid in the CPS (SNACC Phase V, 2010). In the 2002 National Health Interview Survey (NHIS) the undercount was 33.5% (SNACC Phase IV, 2009) and in the 2003 Medical Expenditure Panel Survey Household Component (MEPS/HC) it was 17.5% (SNACC Phase VI, 2010). State sponsored surveys often fare better, but still tend to undercount Medicaid by 12-26% (Call, Davern, Klerman & Lynch, 2013). This mismatch suggests that survey data, relative to what is known from administrative data, give biased estimates of key policy measures such as the share of the population covered by Medicaid or those lacking health insurance. Although survey data on Medicaid is likely biased, unlike administrative data, surveys provide a wide array of policy relevant covariates such as access to health services, health status, and race and ethnicity, and surveys are the only source of information about the uninsured and the eligible but not enrolled.
Modelling tail risk with tempered stable distributions: an overview

In this study, we investigate the performance of different parametric models with stable and tempered stable distributions for capturing the tail behaviour of log-returns (financial asset returns). First, we define and discuss the properties of stable and tempered stable random variables. We then show how to estimate their parameters and simulate them based on their characteristic functions. Finally, as an illustration, we conduct an empirical analysis to explore the performance of different models representing the distributions of log-returns for the S&P500 and DAX indexes.
Cellular mixing with bounded palenstrophy

We study the problem of optimal mixing of a passive scalar $\rho$ advected by an incompressible flow on the two dimensional unit square. The scalar $\rho$ solves the continuity equation with a divergence-free velocity field $u$ with uniform-in-time bounds on the homogeneous Sobolev semi-norm $\dot{W}^{s,p}$, where $s>1$ and $1< p \leq \infty$. We measure the degree of mixedness of the tracer $\rho$ via the two different notions of mixing scale commonly used in this setting, namely the functional and the geometric mixing scale. For velocity fields with the above constraint, it is known that the decay of both mixing scales cannot be faster than exponential. Numerical simulations suggest that this exponential lower bound is in fact sharp, but so far there is no explicit analytical example which matches this result. We analyze velocity fields of cellular type, which is a special localized structure often used in constructions of explicit analytical examples of mixing flows and can be viewed as a generalization of the self-similar construction by Alberti, Crippa and Mazzucato. We show that for any velocity field of cellular type both mixing scales cannot decay faster than polynomially.
High-resolution numerical modelling of flow—vegetation interactions

ABSTRACT In this paper, we present and apply a new three-dimensional model for the prediction of canopy-flow and turbulence dynamics in open-channel flow. The approach uses a dynamic immersed boundary technique that is coupled in a sequentially staggered manner to a large eddy simulation. Two different biomechanical models are developed depending on whether the vegetation is dominated by bending or tensile forces. For bending plants, a model structured on the Euler–Bernoulli beam equation has been developed, whilst for tensile plants, an N-pendula model has been developed. Validation against flume data shows good agreement and demonstrates that for a given stem density, the models are able to simulate the extraction of energy from the mean flow at the stem-scale which leads to the drag discontinuity and associated mixing layer.
Deep Defense: Training DNNs with Improved Adversarial Robustness

Despite the efficacy on a variety of computer vision tasks, deep neural networks (DNNs) are vulnerable to adversarial attacks, limiting their applications in security-critical systems. Recent works have shown the possibility of generating imperceptibly perturbed image inputs (a.k.a., adversarial examples) to fool well-trained DNN classifiers into making arbitrary predictions. To address this problem, we propose a training recipe named "deep defense". Our core idea is to integrate an adversarial perturbation-based regularizer into the classification objective, such that the obtained models learn to resist potential attacks, directly and precisely. The whole optimization problem is solved just like training a recursive network. Experimental results demonstrate that our method outperforms training with adversarial/Parseval regularizations by large margins on various datasets (including MNIST, CIFAR-10 and ImageNet) and different DNN architectures. Code and models for reproducing our results are available at this https URL
Air drying of chopped chestnuts at several conditions: effect on colour and chemical characteristics of chestnut flour

Fresh chopped chestnuts were dried using a hot air convective tray dryer at different temperatures (45, 65 and 85oC) and loading densities (2.5 and 6.3 kg/m 2 ). Drying kinetics were experimentally determined and modelled by means of Page model. Model parameters correlations with temperature and loading density were found. Dried samples were milled and chemical composition (starch, amylose, fat, fibre, proteins, sugars) and colour characteristics of the flour were determined. Total and damaged starch varied significantly with drying temperature and loading density, but not amylose content. Protein and sugars content were also influenced by drying conditions whereas no meaningful differences were observed for fibre and fat content. Lightness of flour chestnut decreased and redness increased with drying temperature. At high loading density, the thermal effects on the flour colour were less promoted.
The Economic Determinants and Engagement Modes of Foreign Banks in Central Europe

In the last fifteen years foreign banks have expanded their presence significantly in almost all developing economies. The transition countries are among those economies that have experienced one of the highest levels of banking internationalization in the world. The foreign controlled banking asset in these countries ranges from 70 per cent in Poland to almost 100 per cent in Slovakia. With our study using panel data we examine the economic determinants of foreign bank engagement in the four local banking markets in Central Europe during the period 1994-2004. In addition, we study whether the economic determinants affect different entry vehicles of foreign banks into the Central European markets. Our results show that the most important factors determining foreign bank engagements were (i) large potential of the Central European banking markets and low degree of their financial sophistication (ii) the legal origin of the home country, (iii) the size of the economic growth rates differentials between host and home markets, and (iv) finally the distance between the host country and the foreign bank headquarter. We also find that most foreign banks investments occurred in the period of poor creditor rights protection. Moreover, our results present that the economic determinants had an impact on the decision of the organization form of the foreign banks entering the Central European banking markets. Our results are robust to several controls, including the lack of independence of investment decisions.
Dispersive Approach to Hadronic Light-by-Light

A recently proposed dispersive approach to hadronic light-by-light is described. In this talk I have presented a dispersive approach to hadronic light-by-light (HLbL) which has been recently proposed in [1]. This approach aims to take into account only the cuts in the hadronic tensor which are due to singleor double-pion intermediate states – this approximation is justified by the fact that in explicit calculations higher-lying singularities (like the one due to two kaons) give small contributions [2]. Further, we split the hadronic tensor as follows: Πμνλσ = Π π0−pole μνλσ + Π FsQED μνλσ + Πμνλσ + · · · , (1) where the first term takes into account the one-pion pole, the second one two-pion intermediate states with simultaneous cuts in the s and t channel (and all possible cyclic permutations including u), and the third one is the one for which we write down a dispersion relation. We briefly discuss the three contributions. 1 Pion pole The dominant contribution to HLbL scattering at low energy is given by the π0-poles. Their residues are determined by the on-shell, doubly-virtual pion transition form factor Fπ0γ∗γ∗ (q1, q2), which is defined as the current matrix element i ∫ d4x eiq·x 〈 0 ∣∣∣T { jμ(x) jν(0)}∣∣∣π0(p)〉 = μναβqαpβFπ0γ∗γ∗(q2, (p − q)2). (2) In these conventions, the π0-pole HLbL amplitude reads Π π0-pole μνλσ = Fπ0γ∗γ∗(q21, q22)Fπ0γ∗γ∗(q23, 0) s − M2 π0 μναβqα1q β 2 λσγδq γ 3k δ + Fπ0γ∗γ∗(q21, q23)Fπ0γ∗γ∗(q22, 0) t − M2 π0 μλαβqα1q β 3 νσγδq γ 2k δ + Fπ0γ∗γ∗(q22, q23)Fπ0γ∗γ∗(q21, 0) u − M2 π0 νλαβqα2q β 3 μσγδq γ 1k .

Association between Red blood cell parameters and immune status in HIV infected males

Background and Objectives: Hematologic changes have been accepted as a powerful predictor of morbidity and mortality in HIV-infected patients. It has been demonstrated that severe anemia is linked with faster rate of HIV disease progression. HIV infection affects hematological indices like MCV (Mean corpuscular volume), MCH (Mean corpuscular haemoglobin) and MCHC (Mean corpuscular hemoglobin concentration) of patients regardless of age, sex and ART. The rationale of this study was to recognize the association between RBC parameters and immune status in male HIV infected patients. Methods: The objective of this study was to consider red blood cell parameters and immune status and to contemplate the relationship between RBC indices and immune status. Results: Among the 48 HIV infected male patients, the CD4 count was significant and positively correlated with the Hemoglobin (HB) and hematocrit (PCV) values. RDW and MCHC were negatively associated but insignificant with CD4 cell count. RBC, MCV and MCH were positively associated but insignificant. CD4 cell count had a wide range with 1376 cells /cmm because of the impact of one patient whose CD4 count was 1435cells/cmm. However, the median was 290 cells /cmm indicating 50% of patients showed deteriorating CD4 cell counts. Conclusion: HIV infection affects the RBC parameters. Anemia is a significant predictor of HIV progression to AIDS. Hemoglobin concentration could be used as a consistent biomarker of the prognosis in HIV-infected patients, and that a therapeutic approach is vital for patients with anemia. There is significant association with reduced CD4 cell count and altered hemoglobin and hematocrit. Evaluation of these parameters certainly improves the condition and endurance of HIV infected patients.
