Good Enough for An Affair. Self–Enhancement of Attractiveness, Interest in Potential Mates and Popularity as A Mate

Using data from the Berlin Speed Dating Study, we tested rival hypotheses concerning the effects of self–enhancement of attractiveness on dating outcomes. Three hundred eighty–two participants took part in one of the 17 speed–dating sessions. After each speed–dating interaction, participants indicated how interesting they found the respective person as a long–term and short–term partner. Using social relations analyses, we computed perceiver effects (being more or less choosy) and target effects (being rated as more or less interesting) of long–term and short–term partner ratings. Self–enhancement was operationalized as the discrepancy between self–rated attractiveness and four components of actual attractiveness (observer–rated facial and vocal attractiveness, height and body mass index). Results indicated that self–enhancers were less choosy with respect to their interest for short–term partners, which was especially true for men, but more choosy with respect to long–term partners. With regard to popularity as a mate, potential partners indicated that they found self–enhancers more interesting as short–term partners but not as long–term partners. As self–enhancement is a key component of narcissism, these results are consistent with findings that narcissists perceive many sexual affairs as an achievement, while preferring selected ‘trophy’ long–term partners, and narcissists have a charming appeal for short–term, but not lasting, social relationships.

UNIQUE CHARACTERISTICS OF COLD CATHODE CARBON-NANOTUBE-MATRIX FIELD EMITTERS

The attributes of electron field emission from disordered matrix arrays of carbon nanotubes are studied and found to be quite reproducible in spite of the disorder, density, and quality variations from sample to sample. At low applied electric fields, the electron field emission current-voltage characteristics qualitatively follow conventional Fowler-Nordheim behavior up to a critical current density. However, the current rise at low applied fields is anomalously steep, suggesting that the Fowler-Nordheim model is not sufficient to quantitatively characterize the emission. In the high-field region, the emission characteristics have a more complex behavior. In that regime, the instantaneous field emission is reminiscent of the low-field behavior, but discrete switching events lead to an overall current suppression. We attribute the sudden and well-defined onset of the switching events to interactions between neighboring nanotube tips. By correlating the switching behavior to the current-voltage characteristics, we rule out other physical processes that cause similar effects. {copyright} {ital 1997} {ital The American Physical Society}
Machine learning-based app for self-evaluation of teacher-specific instructional style and tools

Course instructors need to assess the efficacy of their teaching methods, but experiments in education are seldom politically, administratively, or ethically feasible. Quasi-experimental tools, on the other hand, are often problematic, as they are typically too complicated to be of widespread use to educators and may suffer from selection bias occurring due to confounding variables such as students’ prior knowledge. We developed a machine learning algorithm that accounts for students’ prior knowledge. Our algorithm is based on symbolic regression that uses non-experimental data on previous scores collected by the university as input. It can predict 60–70 percent of variation in students’ exam scores. Applying our algorithm to evaluate the impact of teaching methods in an ordinary differential equations class, we found that clickers were a more effective teaching strategy as compared to traditional handwritten homework; however, online homework with immediate feedback was found to be even more effective than clickers. The novelty of our findings is in the method (machine learning-based analysis of non-experimental data) and in the fact that we compare the effectiveness of clickers and handwritten homework in teaching undergraduate mathematics. Evaluating the methods used in a calculus class, we found that active team work seemed to be more beneficial for students than individual work. Our algorithm has been integrated into an app that we are sharing with the educational community, so it can be used by practitioners without advanced methodological training.
Multi-Criteria Based Recommender System Scalability Optimization : The Approach Based On Clustering of Users

The era of Internet & the ever blooming E- Commerce applications have exposed people to the mines of information and variety of products to choose from while shopping on-line. In such situation it is quite obvious to get lost in exploring abundance of products and related information. This causes the waste of large amount of precious time and may at the same time, create confusion in the minds of prospective on-line shoppers regarding purchasing decision to be made, leading to in-vein search and unfruitful buying attempt. This is categorized as the information overload problem. Recommender systems play an important role in such scenario by presenting the buyer with the ranked list of products preferred by existing buyers for the same/similar products. The number of features or attributes of the product used to determine the order of the product in the ranked list will define the approach used by Recommender system. Traditional approach is called as single criterion based approach for recommender system while the other one is multi-criteria based approach for recommender system. As the number of users of the e- commerce site increases, the time required to form ranked list will also increase with the great amount in case of multi- criteria based recommender systems. This requires optimization criteria to be applied to minimize the time required to form ranked list while maintaining the accuracy of the result.
Compatibility of Transport and Reaction in Membrane Reactors Used for the Oxidative Dehydrogenation of Short-Chain Hydrocarbons

The possibility of process intensification by enhancing selectivity and yield in networks of parallel and series reactions was investigated applying asymmetric multilayer ceramic and sintered metal membranes in a dead-end configuration for a controlled distributed reactant feeding. The oxidative dehydrogenation of ethane to ethylene was selected as a model reaction applying three different doped and/or active VOx/? -Al2O3 catalysts. Experimental investigations were performed in a pilot scale in order to evaluate the potential of a distributed dosing via membranes with respect to operation conditions and compatibility of reaction and membrane properties. It was demonstrated that the rates of reaction and trans-membrane mass transfer have to be compatible for an optimal membrane reactor operation avoiding back diffusion of reactants out of the catalytic zone as well as achieving safety aspects. Therefore, a detailed modeling of the trans-membrane mass transfer under reaction conditions was carried out. As a main result, it was found metal membranes possess a favorable mechanical stability, relatively low costs for production and the possibility to control mass transfer if the rate of reaction and mass transfer in the membrane is compatible which can adjusted by the trans-membrane pressure and the catalyst activity, respectively.
2-dimensional Mapping of Sulfur Dioxide and Bromine Oxide at the Sakurajima Volcano with a Ground Based Scanning Imaging Spectrograph System

A scanning imaging spectrograph system was used in this study to retrieve readings of the 2-D distribution of lTEXg$SO_2$l/TEXg and BrO around the crater of the Sakurajima volcano in Japan. The measurement was carried out during the daytime on November 2, 2005. Measurements were made at the surface of the site, located 5 km from the Sakurajima crater. One hundred horizontal scans were performed. Each column scanned by the system consists of 64 vertical pixels in order to retrieve the spatial distributions of BrO and lTEXg$SO_2$l/TEXg in the plume in terms of slant column densities (SCDs). Measured spectra were analyzed to identify and quantify lTEXg$SO_2$l/TEXg and BrO in the volcanic plume utilizing the plume's specific absorption features in the ultra violet region. Two-dimensional BrO and lTEXg$SO_2$l/TEXg distributions in SCD were retrieved horizontally covering the upwind, crater and downwind areas, and vertically, including the plume in the center of the scanned image. Both horizontal and vertical dispersions of lTEXg$SO_2$l/TEXg SCD from the crater were successfully measured to be from lTEXg$10^{17}$l/TEXg to lTEXg$4.5{\times}10^{18}$l/TEXg molecules lTEXg$cm^{-2}$l/TEXg. However, BrO was measured below lTEXg$10^{15}$l/TEXg molecules lTEXg$cm^{-2}$l/TEXg, which is considered its background level.
Bialgebra and Hopf algebra structures on free Rota-Baxter algebras

In this paper, we obtain a canonical factorization of basis elements in free Rota-Baxter algebras built on bracketed words. This canonical factorization is applied to give a coalgebra structure on the free Rota-Baxter algebras. Together with the Rota-Baxter algebra multiplication, this coproduct gives a bialgebra structure on the free Rota-Baxter algebra of rooted forests. When the weight of the Rota-Baxter algebra is zero, we further obtain a Hopf algebra structure.
Mitochondrial COI Gene Sequence Analyses of Puntius ticto and Compared with Seven Species of Genus Puntius of Family Cyprinidae: A Finding for Phylogenetic Positioning and DNA Barcoding as Model Study for Cryptic Species

Over the last three decades, mitochondrial DNA (mtDNA) has declared as the most popular marker of molecular diversity, for a combination of technical ease-of-use considerations, and supposed biological and evolutionary properties of a species. The present study examined partial mitochondrial cytochrome c oxidase subunit I gene sequence of mitochondrial DNA for phylogenetic positioning of Puntius ticto among eight species of genus Puntius and its suitability to determine the genetic differentiation in among genus Puntius. The 05 samples of P. ticto were collected from Halali reservoir were analyzed mtcox1 gene of mitochondrial partial regions were sequenced and compared with the online database available on NCBI (National Centre for Biotechnology Information, USA) for rest of seven species (P. sophore, P. sarana, P. amphibious, P. chola, P. conchonius, P. dorsalis and P. gelius). Sequencing of 668 bp of mtcox1 gene revealed 18 haplotypes (h) with haplotype (gene) diversity (Hd) 0.981 ± 0.023 and nucleotide diversity (Pi) 0.658. 504 variable sites and parsimony sites have been recorded and conserved positions were observed at equal frequency in the nucleotide sequence and the variable regions were mostly visualized between nucleotide 27 to 76. The results concluded that the partial mtcox1 is polymorphic and can be a potential marker to determining phylogenetic positioning of Puntius ticto with rest of seven species. Present investigation may be treated model study for wildlife scientists for banding smuggling protected species under false pretenses and the importance of DNA barcoding in stopping such illegal trade.
Gender Differences on Airway Obstruction in Smokers

Objectives: Published data on gender differences in the effect of smoking on pulmonary function have been controversial. The study was designed to investigate the gender differences in effects of smoking on pulmonary function. Methods: Female smokers were chosen among individuals older than 40 yrs, living in home for the aged. Male smokers were chosen from among office workers older than 40 yrs in MCI (machine chemical industry). Total 215 female smokers and 283 male smokers included the study. The individuals were interrogated with a questionnaire concerning respiratory symptoms, smoking status and other characteristics. Chronic airway obstruction was defined by FEV1/FVC <70%. Results: The prevalence of chronic bronchitis in male smokers was similar to those of female smokers. The prevalence of airflow obstruction was higher in male smokers than female smokers [11.0% vs 3.7%, OR=3.1 (95%CI 1.4 to 7.0), p=0.003, respectively]. The man smokers compared to women smokers had lower values of the ratio forced expiratory volume in 1 second to forced vital capacity (FEV1/FVC) (81.1 ± 8.3 vs 86.9 ± 7.9, p=0.0001, respectively) and lower the dyspnea score. FEV1/FVC was an important predictor for magnitude of dyspnea, after adjusting for confounding factors in all subjects in regression analysis. Conclusions: Male smokers have more severe airway obstruction and lower perception of dyspnea than female smokers with similar age and smoking burden. The males are particularly prone than females to the negative effects of smoking. Individuals' perceptions of airway obstruction and response to cigarette smoke vary depending on gender.
Evaluation of IRS1D-LISS-III and Landsat 8-OLI Images for Mapping in Maroon Riparian Forest, Iran

In order to compare the mapping by IRS1D-LISSIII and Landsat 8-OLI data in Riparian forest of Maroon Behbahan of Iran, the small window of panchromatic and multispectral images of IRS1D-LISSIII, and Landsat 8-OLI satellites data have been selected at Maroon riparian forest. Quality of data and radiometric error has been checked. Using 25 ground control points, geometric correction, whose accuracy was less than 5.0 pixels, has been implemented. Classification of images has been performed by supervised method using Maximum Likelihood and SVM algorithms for seven classes on the original bands. Moreover, Jeffreys-Matusita Method has been employed in order to test the separability of classes. Considering to the results, it can be concluded that IRS1D-LISS-III and Landsat 8-OLI data have suitable ability for mapping Maroon riparian forest as well as classification of forest to separate land use. Overall accuracy of classification obtained by OLI images and using SVM algorithm on original bands was 92/95. Furthermore, kappa coefficient was 0/85 percent which was the best result. In general, it should be notified that according to the presented study, OLI sensor can be considered as a more accurate method than LISS Ð¨ in order to map Maroon riparian forests.
VARIANCE ANISOTROPY IN KINETIC PLASMAS

Solar wind fluctuations admit well-documented anisotropies of the variance matrix, or polarization, related to the mean magnetic field direction. Typically, one finds a ratio of perpendicular variance to parallel variance of the order of 9:1 for the magnetic field. Here we study the question of whether a kinetic plasma spontaneously generates and sustains parallel variances when initiated with only perpendicular variance. We find that parallel variance grows and saturates at about 5% of the perpendicular variance in a few nonlinear times irrespective of the Reynolds number. For sufficiently large systems (Reynolds numbers) the variance approaches values consistent with the solar wind observations.
The Supervisory Working Alliance: its Relation To Trainee Self-Efficacy and Satisfaction With Supervision

This study was conducted to test Bordin's (1983) proposition that, in supervision, counselor trainees' perceptions of the supervisory working alliance (goals, tasks, and an emotional bond) are predictive of supervisory outcomes (trainee self-efficacy and trainee satisfaction with supervision) over time. Beginning practicum to intern level counselor trainees (N-.107) completed the Working Alliance Inventory, the Self-Efficacy Inventory, the Trainee Personal Reaction Scale, and a demographic questionnaire that also assessed trainee experience level. The results indicated that changes in the supervisory working alliance were not predictive of changes in trainee self-efficacy. Changes in the supervisory working alliance, however, were predictive of trainee satisfaction with supervision. Bordin's model and theoretical propositions were supported by the findings in that the supervisory working alliance was significantly related to one aspect of supervision outcome. The results seemed to provide evidence which suggests that the supervisory working alliance changes over time and this change needs to be considered when evaluating its effectiveness.

Comprehensive Review of RunoffEstimation by the Curve Number Method

Rainfall-runoff relationship is one of the most important phenomena in hydrologic design of hydrological structures and drainage systems. The estimation of runoff volume of a catchment is an important aspect in engineering planning, environmental impact assessment, flood forecasting and water balance calculations. There are basically two types of methods for the estimation of runoff namely the direct method and the indirect method. The direct method is based on the direct measurements while the other one is based on the equations. One of the indirect methods for the computation of runoff is the National Resource Conservation Service curve number method. This paper gives a review of the origin of the curve number method and development of the curve number equations. The Natural Resource Conservation Service curve number technique is a well-accepted tool for estimation of direct runoff from storm rainfall. CN model is used where constraints like slope, land cover, type of soil, area of watershed etc. are considered for runoff estimation.
Revista Mexicana de Biodiversidad

Eighty-six specimens representing 7 species of rodents from 9 localities in the state Zacatecas were examined for helminths. Only 5 host species were found to harbor at least 1 species: Chaetodipus sp. , Dipodomys merriami atronasus , Neotoma mexicana, Otospermophilus variegatus , and Peromyscus sp. ; in contrast Mus musculus and Reithrodontomys sp. , were not parasitized. Three species of cestodes (Catenotaeniidae gen. sp., Hymenolepis sp., and Raillietina sp.) and 7 nematodes ( Gongylonema sp., Heteromyoxyuris longejector , Lamotheoxyuris cf. ackerti , Mastophorus dipodomis , Rauschtineria sp., Pterygodermatites dipodomis , and Trichuris dipodomis ) were recorded. The intestine is the most parasitized (7 taxa) and trematodes were not found. The highest species richness was recorded in D. merriami atronasus from Rancho La Barranca (6 taxa), which also had the most sampling effort. H. longejector in Chaetodipus sp. from El Gordillo, showed the greatest mean abundance, and mean intensity values, followed by Rauschtineria sp. in O. variegatus from Morelos-Zacatecas Road. All species are new locality records, 14 new host records, and 2 taxa recorded for the ﬁrst time in Mexico: Rauschtineria sp. and M. dipodomis . This is the ﬁrst study of helminth parasites of rodents from Zacatecas. © 2016 Universidad Nacional Autónoma de México, Instituto de Biología.

Taxonomic review of the genus Luciobarbus Heckel, 1843 (Actinopterygii, Cyprinidae) from northwestern Morocco with the description of three new species

The genus Luciobarbus in Morocco presents high diversification, in contrast to the generally impoverished freshwater fish fauna from North Africa. Within Morocco the northern area is one of the least studied territories, due to both its historical background and the limited accessibility of many regions. Previous phylogenetic studies identified Luciobarbus populations that are morphologically and genetically differentiated, to the same extent as others already recognized as separate species. The aim of this work is to describe these populations as distinct species, based on morphological, meristic, and genetic traits. urn:lsid:zoobank.org:pub:8FC4B423-104C-4097-A468-ED3D2664A15A
Journal of Geophysical Research: Solid Earth Postseismic GRACE and GPS observations indicate a rheology contrast above and below the Sumatra slab

More than 7 years of observations of postseismic relaxation after the 2004 Sumatra-Andaman earthquake provide an improving view on the deformation in the wide vicinity of the 2004 rupture. We include both Gravity Recovery and Climate Experiment (GRACE) gravity ﬁeld data that show a large postseismic signal over the rupture area and GPS observations in the back arc region. With increasing time GPS and GRACE show contrasting relaxation styles that were not easily discernible on shorter time series. We investigate whether mantle creep can simultaneously explain the far-ﬁeld surface displacements and the long-wavelength gravity changes. We interpret contrasts in the temporal behavior of the GPS-GRACE observations in terms of lateral variations in rheological properties of the asthenosphere below and above the slab. Based on 1-D viscoelastic models, our results support an (almost) order of magnitude contrast between oceanic lithosphere viscosity and continental viscosity, which likely means that the low viscosities frequently found from postseismic deformation after subduction earthquakes are valid only for the mantle wedge. Next to mantle creep, we also consider afterslip as an alternative mechanism for postseismic deformation. We investigate how the combination of GRACE and GPS data can better discriminate between diﬀerent mechanisms of postseismic relaxation: distributed deformation (mantle creep) versus localized deformation (afterslip). We conclude that the GRACE-observed gravity changes rule out afterslip as the dominant mechanism explaining long-wavelength deformation even over the ﬁrst year after the event.
Measurement of snow interception and canopy effects on snow accumulation and melt in a mountainous maritime climate, Oregon, United States

The results of a 3 year field study to observe the processes controlling snow interception by forest canopies and under canopy snow accumulation and ablation in mountain maritime climates are reported. The field study was further intended to provide data to develop and test models of forest canopy effects on beneath‐canopy snowpack accumulation and melt and the plot and stand scales. Weighing lysimeters, cut‐tree experiments, and manual snow surveys were deployed at a site in the Umpqua National Forest, Oregon (elevation 1200 m). A unique design for a weighing lysimeter was employed that allowed continuous measurements of snowpack evolution beneath a forest canopy to be taken at a scale unaffected by variability in canopy throughfall. Continuous observations of snowpack evolution in large clearings were made coincidentally with the canopy measurements. Large differences in snow accumulation and ablation were observed at sites beneath the forest canopy and in large clearings. These differences were not well described by simple relationships between the sites. Over the study period, approximately 60% of snowfall was intercepted by the canopy (up to a maximum of about 40 mm water equivalent). Instantaneous sublimation rates exceeded 0.5 mm per hour for short periods. However, apparent average sublimation from the intercepted snow was less than 1 mm per day and totaled approximately 100 mm per winter season. Approximately 72 and 28% of the remaining intercepted snow was removed as meltwater drip and large snow masses, respectively. Observed differences in snow interception rate and maximum snow interception capacity between Douglas fir (Pseudotsuga menziesii), white fir (Abies concolor), ponderosa pine (Pinus ponderosa), and lodgepole pine (Pinus contorta) were minimal.
