Organizational career management practices, career satisfaction, and intention to quit among Indian employee: Examining the moderating effect of ‘four types of work experience’

This study examined the interactive effect of organizational career management practices and different types of work experience on career satisfaction and intention to quit the organization in 386 Indian employees. The results showed that after controlling for the effect of the demographic variables and organizational career management practices, different types of work experience played unique roles in predicting career satisfaction and intention to quit the organization. It was found that that organizational career management practices correlated positively with career satisfaction and negatively with intention to quit the organization. The results further showed that organizational experience moderated the relationship between organizational career management practices and career satisfaction, and organizational tenure moderated the relationship between organizational career management practices and intention to quit. These findings carry implication for research and practice on career satisfaction and intention to quit the organization.
Age Estimation Robust to Expression Variations

In this paper, we present a novel age estimation method that is able to deal with varying face expressions. We construct two efficient descriptors for face appearance which are robust to expression variations. One is termed as Proportion Descriptor constructed by proportion indices based on facial geometric features, the other is termed as Local Descriptor based on local facial texture features extracted by Modular Principle Component Analysis (MPCA). We set up experiments for evaluating the performance of the two facial descriptors in the presence of facial expressions.
Can large N{sub c} equivalence between supersymmetric Yang-Mills theory and its orbifold projections be valid?

In previous work, we found that necessary and sufficient conditions for large N{sub c} equivalence between parent and daughter theories, for a wide class of orbifold projections of U(N{sub c}) gauge theories, are just the natural requirements that the discrete symmetry used to define the projection not be spontaneously broken in the parent theory, and the discrete symmetry permuting equivalent gauge group factors not be spontaneously broken in the daughter theory. In this paper, we discuss the application of this result to Z{sub k} projections of N=1 supersymmetric Yang-Mills theory in four dimensions, as well as various multiflavor generalizations. Z{sub k} projections with k>2 yielding chiral gauge theories violate the symmetry realization conditions needed for large N{sub c} equivalence, due to the spontaneous symmetry breaking of discrete chiral symmetry in the parent super-Yang-Mills theory. But for Z{sub 2} projections, we show that previous assertions of large N{sub c} inequivalence, in infinite volume, between the parent and daughter theories were based on incorrect mappings of vacuum energies, theta angles, or connected correlators between the two theories. With the correct identifications, there is no sign of any inconsistency. A subtle but essential feature of the connection between parent and daughter theories involvesmore » multivaluedness in the mapping of theta parameters from parent to daughter. « less
Where populist citizens get the news: An investigation of news audience polarization along populist attitudes in 11 countries

ABSTRACT This article presents a secondary analysis of two multi-national cross-sectional surveys conducted in 2015 (11 countries, N = 10,570) and 2017 (4 countries, N = 2165) to examine the relationship between populist attitudes and media use. The results indicate that populist citizens are more likely to consume news than non-populist citizens. Specifically, populist citizens exhibit a preference for commercial television (TV) news, as well as a tendency to read tabloid newspapers. While they use fewer quality newspapers, public TV news are not systematically avoided. Regarding the online news environment, populist citizens prefer Facebook over Twitter as a source of political information. This selective pattern will be discussed in light of the debates on news audience polarization and political polarization.
Threats to student evaluative judgement and their management

ABSTRACT Students’ capacity for making evaluative judgements of their own work is widely acknowledged as central to their learning within programmes as well as being vital to their subsequent professional practice. In higher education literature, the act of evaluative judgement is usually portrayed as a process of deliberative, analytical reasoning requiring student agency and objectivity, typically scaffolded by points of reference such as explicit criteria, rubrics or exemplars. This article challenges this common portrayal of judgement by drawing attention to research from outside higher education on the role of unconscious factors in judgement and decision-making. Drawing from the field of heuristics and bias studies, the article outlines six unconscious factors that have the potential to distort students’ analytical judgement of their work. A recent challenge to the heuristics and bias approach that radically repositions the place of reasoning in judgement is also considered. Since these unconscious factors have received scant attention in higher education literature, the purpose of this article is to draw attention to them, to identify the challenges they pose to current understandings of evaluative judgement, and to outline their implications for enhancing assessment practice.
Minerals and chosen heavy metals retention in immature common bean (Phaseolus vulgaris L.) seeds depending on the method of preservation.

BACKGROUND Legumes are a good source of protein, and are also abundant in carbohydrates, B-group vita-mins, dietary fibre and mineral compounds. MATERIAL AND METHODS This work evaluates the retention of ash, eleven minerals and two heavy metals in products obtained from two common bean cultivars harvested before reaching full maturity, with a dry matter content of about 40%. Analyses were conducted on raw, blanched and cooked seeds and three products prepared for consumption after 12-month storage: two frozen and one canned (sterilized). The former comprised two types of frozen product: one traditionally produced (blanching-freezing-frozen storage-cooking), the other a convenience, "ready-to-eat" product obtained using a modified method (cooking-freezing-frozen storage-defrosting-heating to consumption temperature in a microwave oven). RESULTS In cooked bean seeds of both cultivars, levels of potassium, calcium, magnesium and copper were significantly lower, the only exception being the content of ash and sodium (due to added salt), than in blanched seeds; the changes in the remaining components were not so clear-cut and depended on the cultivar. Seeds frozen using the modified technology generally showed higher levels of the elements investigated than frozen products produced traditionally, with the exception of chromium, nickel and lead. Sterilized seeds had lower levels of ash, phosphorus, calcium, magnesium, iron, zinc, manganese, copper and chromium compared with both types of frozen product; retention levels of individual components depended on the cultivar examined. Conclusions. Compared with the traditionally produced frozen product, prepared for consumption, seeds after modified method of freezing (convenience food) contained significantly higher levels of ash and all macroelements, regardless of the cultivar. Seeds preserved by sterilization, compared with frozen seeds (either method of production) prepared for consumption, had lower content of most of the analyzed components.
Microscopic Origin of Interfacial Dzyaloshinskii-Moriya Interaction

Chiral spin textures at the interface between ferromagnetic and heavy nonmagnetic metals, such as Neel-type domain walls and skyrmions, have been studied intensively because of their great potential for future nanomagnetic devices. The Dyzaloshinskii-Moriya interaction (DMI) is an essential phenomenon for the formation of such chiral spin textures. In spite of recent theoretical progress aiming at understanding the microscopic origin of the DMI, an experimental investigation unravelling the physics at stake is still required. Here, we experimentally demonstrate the close correlation of the DMI with the anisotropy of the orbital magnetic moment and with the magnetic dipole moment of the ferromagnetic metal. The density functional theory and the tight-binding model calculations reveal that asymmetric electron occupation in orbitals gives rise to this correlation.
Separation of sound sources by convolutive sparse coding

An algorithm for the separation of sound sources is presented. Each source is parametrized as a convolution between a time-frequency magnitude spectrogam and an onset vector. The source model is able to represent several types of sounds, for example repetitive drum sounds and harmonic sounds with modulations. An iterative algorithm is proposed for the estimation the parameters. The algorithm is based on minimizing the reconstruction error and the number of onsets. The number of onsets is minimized by applying the sparse coding scheme for onset vectors. A way of modeling the loudness perception of the human auditory system is proposed. The method compresses high-energy sources, and enables the separation of lowenergy sources which are perceptually significant. The algorithm is able to separate meaningful sources from real-world signals. Simulation experiments were carried out using mixtures of harmonic instruments. Demonstration signals are available at http://www.cs. tut.fi/~tuomasv/demopage.html.
Direct Measurement of Scientific Giftedness

Giftedness in science today is largely measured by various kinds of standardized tests—IQ tests, SATs, ACTs, GREs, and so forth. For example, many STEM (science, technology, engineering, math) gifted programs rely at least in part on IQ tests or the SAT for identifying students as gifted. It might be useful to supplement such standard measures with measures that directly measure the skills involved in actual scientific work, such as (a) generating hypotheses, (b) generating experiments, (c) drawing conclusions, (d) reviewing (i.e., analyzing scientific work), (e) editing (i.e., evaluating reviews of scientific work), and (f) evaluating teaching. This article discusses the status of the measurement of scientific giftedness and also describes assessments designed to measure scientific giftedness as well as giftedness in evaluating teaching (an important component of scientific success).
The Stuff That Verbal Person-Centered Support Is Made of: Identifying Linguistic Markers of More and Less Supportive Conversations

Although the functions of messages varying in verbal person centeredness (PC) are well-established, we know less about the linguistic content that differentiates messages with distinct levels of PC. This study examines the lexicon of different levels of PC comfort and seeks to ascertain whether computerized analysis can complement human coders when coding supportive conversations. Transcripts from support providers trained to enact low, moderate, or high levels of PC were subjected to the Linguistic Inquiry and Word Count (LIWC) dictionary. Results reveal that several categories in the LIWC dictionary vary systematically as a function of conversational PC level. LIWC categories, particularly pronouns, social process, cognitive process, anxiety, and anger words, reliably predict which level of the PC hierarchy an interaction represents based on whether a conversation was designed to be high, moderate, or low in PC. The implications are discussed in the context of the lexicon of conversations that vary in PC.
A Large-Area Search for Low-Mass Objects in Upper Scorpius. II. Age and Mass Distributions

We present continued results from a wide-field, ~150 deg2, optical photometric and spectroscopic survey of the northern part of the ~5 Myr old Upper Scorpius OB association. Photometry and spectral types were used to derive effective temperatures and luminosities and place newly identified association members onto a theoretical Hertzsprung-Russell diagram. From our survey, we have discovered 145 new low-mass members of the association and determined ~10% of these objects to be actively accreting material from a surrounding circumstellar disk. Based on comparison of the spatial distributions of low- and high-mass association members, we find no evidence for spatial segregation by mass within the northern portion of the association. Measured data are combined with pre-main-sequence evolutionary models to derive a mass and age for each star. Using Monte Carlo simulations, we show that, taking into account known observational uncertainties, the observed age dispersion for the low-mass population in USco is consistent with all stars forming in a single burst ~5 Myr ago, and we place an upper limit of ±3 Myr on the age spread if the star formation rate has been constant in time. We derive the first spectroscopic mass function for USco that extends into the substellar regime and compare these results to those for three other young clusters and associations.
Citizenship Status, Warm Glow, and Prosocial Behavior: A Quasi-Experiment on Giving Behavior by Host-Country Citizens and Asylum Seekers

Abstract This paper is concerned with the question of whether and how social class and status affect prosocial behavior among status groups.We conducted dictator games in which both host-country citizens (high social status) as well as asylum seekers (low social status) make monetary donations towards their respective in- and out-groups. As a novelty, we varied the number of recipients in the dictator game (i.e. one, two or three recipients). Our results indicate that host-country citizens donate significantly more than asylum seekers and that asylum seekers receive significantly higher donations than host-country citizens. Donations vary only marginally with the number of recipients. These findings and answers to a follow-up questionnaire show that prosocial behavior among status groups, and in particular prosocial behavior from high-status towards low-status actors, might be instances of impure altruism, i.e., motivated by a warm glow of giving or a purchase of moral satisfaction.
Factors Shaping the Agency of Beginning Science Teachers Working in High-Poverty Schools

ABSTRACT The national shortage of science teachers and the substantial teacher turnover rate in high-poverty schools are outcomes of multiple issues. Using a framework built on 2 constructs—teacher agency (typically examined in experienced rather than beginning teachers) and professional identity—we investigate how agency and identity interact and might be used to explain teachers’ perceptions of and responses tao challenges. We present a case study of 3 secondary science teachers committed to teaching in high-needs contexts and show that in spite of challenges they faced regularly, these individuals worked to achieve the goals associated with their primary values. On the basis of our analysis, we propose that teacher agency establishes the foundation for the retention of teachers in the profession, especially those whose careers are in particularly challenging contexts.
Obesity as Compared With Physical Activity in Predicting Risk of Coronary Heart Disease in Women

Background— The comparative importance of physical inactivity and obesity as predictors of coronary heart disease (CHD) risk remains unsettled. Methods and Results— We followed 88 393 women, 34 to 59 years of age, in the Nurses’ Health Study from 1980 to 2000. These participants did not have cardiovascular disease and cancer at baseline. We documented 2358 incident major CHD events (including nonfatal myocardial infarction and fatal CHD) during 20 years of follow-up, including 889 cases of fatal CHD and 1469 cases of nonfatal myocardial infarction. In a multivariate model adjusting for cardiovascular risk factors, overweight and obesity were significantly associated with increased risk of CHD, whereas increasing levels of physical activity were associated with a graded reduction in CHD risk (P<0.001). In joint analyses of body mass index (BMI) and physical activity in women who had a healthy weight (BMI, 18.5 to 24.9 kg/m2) and were physically active (exercise ≥3.5 h/wk) as the reference group, the relative risks of CHD were 3.44 (95% confidence interval [CI], 2.81 to 4.21) for women who were obese (BMI ≥30 kg/m2) and sedentary (exercise <1 h/wk), 2.48 (95% CI, 1.84 to 3.34) for women who were active but obese, and 1.48 (95% CI, 1.24 to 1.77) for women who had a healthy weight but were sedentary. In combined analyses of waist-hip ratio and physical activity, both waist-hip ratio and physical activity were significant predictors of CHD, and the highest risk was among women in the lowest category of physical activity and the highest tertile of waist-hip ratio (relative risk=3.03; 95% CI, 1.96 to 4.18). Even a modest weight gain (4 to 10 kg) during adulthood was associated with 27% (95% CI, 12% to 45%) increased risk of CHD compared with women with a stable weight after adjusting for physical activity and other cardiovascular risk factors. Conclusions— Obesity and physical inactivity independently contribute to the development of CHD in women. These data underscore the importance of both maintaining a healthy weight and regular physical activity in preventing CHD.
Functional Genomics Approach for Identification of Molecular Processes Underlying Neurodegenerative Disorders in Prion Diseases

Prion diseases or transmissible spongiform encephalopathies (TSEs) are infectious neurodegenerative disorders leading to death. These include Cresutzfeldt-Jakob disease (CJD), familial, sporadic and variant CJD and kuru in humans; and animal TSEs include scrapie in sheep, bovine spongiform encephalopathy (BSE) in cattle, chronic wasting disease (CWD) of mule deer and elk, and transmissible mink encephalopathy. All these TSEs share common pathological features such as accumulation of mis-folded prion proteins in the central nervous system leading to cellular dysfunction and cell death. It is important to characterize the molecular pathways and events leading to prion induced neurodegeneration. Here we discuss the impact of the functional genomics approaches including microarrays, subtractive hybridization and microRNA profiling in elucidating transcriptional cascades at different stages of disease. Many of these transcriptional changes have been observed in multiple neurodegenerative diseases which may aid in identification of biomarkers for disease. A comprehensive characterization of expression profiles implicated in neurodegenerative disorders will undoubtedly advance our understanding on neuropathology and dysfunction during prion disease and other neurodegenerative disorders. We also present an outlook on the future work which may focus on analysis of structural genetic variation, genome and transcriptome sequencing using next generation sequencing with an integrated approach on animal and human TSE related studies.
SET-INVARIANT ESTIMATORS FOR LINEAR SYSTEMS SUBJECT TO DISTURBANCES AND MEASUREMENT NOISE

Abstract The concept of set-invariance is applied to the design of full-order state observers with limitation of the estimation error, for discrete-time linear systems subject to unknown but bounded persistent disturbances and measurement noise. It is shown that if the initial error belongs to a D -( C, A )-invariant set, then it can be kept in this set by means of a suitable output injection, for all admissible disturbances and noise. Polyhedral D -( C, A )-invariant sets are explicitly characterized by necessary and sufficient conditions. Based on such conditions, algorithms are proposed for the computation of a D -( C, A )-invariant polyhedron containing the one to which the initial error belongs. The results are illustrated and compared to other approaches by means of a numerical example.
Universität Des Saarlandes Fachrichtung 6.1 – Mathematik Lucas/kanade Meets Horn/schunck: Combining Local and Global Optic Flow Methods Lucas/kanade Meets Horn/schunck: Combining Local and Global Optic Flow Methods

Differential methods belong to the most widely used techniques for optic flow computation in image sequences. They can be classified into local methods such as the Lucas–Kanade technique or Bigün's structure tensor method, and into global methods such as the Horn/Schunck approach and its extensions. Often local methods are more robust under noise, while global techniques yield dense flow fields. The goal of this paper is to contribute to a better understanding and the design of differential methods in four ways: (i) We juxtapose the role of smoothing/regularisation processes that are required in local and global differential methods for optic flow computation. (ii) This discussion motivates us to describe and evaluate a novel method that combines important advantages of local and global approaches: It yields dense flow fields that are robust against noise. (iii) Spatiotemproal and nonlinear extensions to this hybrid method are presented. (iv) We propose a simple confidence measure for optic flow methods that minimise energy functionals. It allows to sparsify a dense flow field gradually, depending on the reliability required for the resulting flow. Comparisons with experiments from the literature demonstrate the favourable performance of the proposed methods and the confidence measure.
Different practice effects for males and females by psychometric and chronometric mental-rotation tests

ABSTRACT Gender differences in the psychometric mental-rotation test are usually larger than in the chronometric version. In both tests, practice effects appear for males and females. In this study, 104 participants (54 females, 50 males, age: 21.72 years) completed both tests in counterbalanced order. In the chronometric test, only males reacted and rotated significantly faster after the practice with the psychometric test. A strong practice effect independently of gender was found in the psychometric test and a gender difference in accuracy in favour of males. Males reported more confidence and females rated the perceived pressure of the time limit of the psychometric test higher than males. Consequently, differences in confidence after the practice could partly explain the gender differences in the improvements of reaction time and rotational speed. Practice from one mental-rotation test on the performance in another seems to be dependent of participants’ gender and the type of the test.
