The effect of transformational leadership on innovative work behavior with moderating role of internal locus of control and psychological empowerment

The current study examined the effect of the style of transformational leadership on innovative work behavior as well as the internal locus of control’s moderating role and psychological empowerment between the relationships of them. We collected data from 422 respondents who are related to family business in Malaysia. Path coefficient analysis was employed to test the hypotheses and SPSS software was used for analyzing descriptive data. The results showed that transformational leadership style, psychological empowerment and internal locus of control have affirmative relationship and significant impact on innovative work behavior. Finally, psychological empowerment and internal locus of control were not found to have moderating effect between innovative work behavior and the style of transformational leadership.
Generalized Market Uncertainty Measurement in European Stock Markets in Real Time

We estimate generalized market uncertainty indicators for the stock markets of eight European countries greatly affected by the recent Covid-19 crisis and the economic measures implemented for its containment and mitigation. Our statistics emphasize the difference between risk and uncertainty, in the aggregate, and provide readily and easily interpretable estimates, in real time, which are relevant for market participants and regulators. We show that generalized uncertainty in Europe was, indeed, at historically high levels in the wake of the recent public health crisis before the large interventions by the European Central Bank, the Fed, and the Bank of England, but also that, for some markets, recently recorded uncertainty levels were still lower than those recorded during the Global Financial Crisis, which puts things into perspective. We also show that uncertainty shocks are extremely persistent, but such persistence varies greatly across countries. The period needed for the markets to absorb half of the shock lies between less than a year and two and a half years.
Myrtus communis in Tunisia: variability of the essential oil composition in natural populations

The essential oil of 12 Tunisian natural populations of Myrtus communis L. (Myrtacea), prospected in three bioclimatic stages (humid inferior, sub-humid and semi-arid superior) were analyzed. Oil was extracted by n-hexane from crushed leaves and analysed by GC and GC-MS. Twenty-four components, representing approximately 79.10% of the oil, were identified. The major constituents were α-pinene (19.20%) and 1,8-cineole (15.96%). The other important constituents were linalool (7.66%), α-terpineol (7.51%) and limonene (5.75%). The percentage of all components varied within and among populations according to their bioclimatic appurtenance. α-Pinene, camphene and 1,8-cineole were the main compounds to differentiate the populations according to the bioclimate.

Data-driven computational models reveal perceptual simulation in word processing

In their strongest formulation, theories of grounded cognition claim that concepts are made up of sensorimotor information. Following such equivalence, perceptual properties of objects should consistently influence processing, even in purely linguistic tasks, where perceptual information is neither solicited nor required. Previous studies have tested this prediction in semantic priming tasks, but they have not observed perceptual influences on participants’ performances. However, those findings suffer from critical shortcomings, which may have prevented potential visually grounded/perceptual effects from being detected. Here, we investigate this topic by applying an innovative method expected to increase the sensitivity in detecting such perceptual effects. Specifically, we adopt an objective, data-driven, computational approach to independently quantify vision-based and language-based similarities for prime-target pairs on a continuous scale. We test whether these measures predict behavioural performance in a semantic priming mega-study with various experimental settings. Vision-based similarity is found to facilitate performance, but a dissociation between vision-based and language-based effects was also observed. Thus, in line with theories of grounded cognition, perceptual properties can facilitate word processing even in purely linguistic tasks, but the behavioural dissociation at the same time challenges strong claims of sensorimotor and conceptual equivalence.
Numerical Analysis of a Hydrodynamic Herringbone Grooved Journal Bearing

In hydrodynamic lubrication, at very high rotational speed, the phenomenon of axial fluid leakage is often present. This can involve an increase of shear stress in the contact and consequently a considerable increase of the temperature. For that and in order to solve this problem, we took interest in the herringbone grooved journal bearings. The researches made before on these types of groove bearing have shown that they present a good dynamical behavior with a low eccentricity and a low axial flow. In this paper, a numerical study of a herringbone journal bearing operating behavior, under laminar and isothermal regime, is presented. The theoretical model, based on the classical Reynolds equation, is used. In order to include the film rupture and reformation, the Reynolds equation is modified using a mass conservative algorithm. To understand the behavior of these herringbone grooved journal bearings well, numerical modeling, using finite element method, has been developed. Various geometrical shapes of the herringbone grooved journal bearings have been analyzed, allowing us to limit the fluid leakage problem, by working particularly on the contact form.
Factors affecting the effect of exploitation and exploration on performance: A meta-analysis

From a contingency view, we aim to contribute to a better understanding of how exploitation and exploration influence performance. By conducting a meta-analysis, we aim to answer the following research question: How do substantive moderators (slack resources, organizational structure, inter-organizational relationships, competitive intensity, and environmental dynamism), extrinsic moderators (region, size, and sector) and methodological moderators (data sources and performance measurement) affect the impact of exploitation and exploration on performance? The results of the meta-analysis, including 328 correlations, 102 studies, and a sample of 41,298 cases, suggest that the influence of exploitation and exploration on performance depends on the presence of the moderating factors included in our analysis. Furthermore, some of these factors are relevant for explaining a better performance of exploitation versus exploration, while other moderators do not determine a different effect of exploitation and exploration on performance.

Long time dynamics of a polymer with rigid body monomer units relating to a protein model: Comparison with the rouse model

Simulation data from an off‐lattice polymer model are compared with data from the Rouse model. The polymer model is built of sequentially connected rigid monomer units that represent the amide planes of a protein backbone. The time propagation of the dynamics of the polymer model is performed by a Monte Carlo method. The elementary Monte Carlo steps correspond to local confomational changes in a window of three consecutive monomer units. The time autocorrelation functions of end‐to‐end distances from segments within the linear chain molecule are considered in detail. Both models exhibit a stretched exponential decay pattern. A comparison of the data from the Rouse model and the computer simulation provide an estimate of the time unit of 15 ps for a full scan of the algorithm for local conformational changes along the chain. With a conservative estimate of the parameters governing the Rouse model this time unit is four orders of magnitude longer than the elementary time step of a conventional computer simulation of polymer dynamics based upon the classical equations of motion for all atoms. © 1992 by John Wiley & Sons, Inc.
Thermal Accelerometer Simulation by the R‑Functions Method

As well as many modern devices, thermal accelerometers (TAs) need a sophisticated mathematical simulation to find the ways for their performance optimization. In the paper, a novel approach for solving computational fluid dynamics (CFD) problems in the TA’s cavity is proposed (MQ-RFM), which is based on the combined use of Rvachev’s R-functions method (RFM) and the Galerkin technique with multiquadric (MQ) radial basis functions (RBFs). The semi-analytical RFM takes an intermediate position between traditional analytical approaches and numerical methods, such as the finite-element method (FEM), belonging to the family of the so-called meshless techniques which became popular in the last decades in solving various CFD problems in complex-shaped cavities. Mathematical simulation of TA by using the MQ-RFM was carried out with the purpose to simulate the temperature response of the device and to study and improve its performance. The results of numerical experiments were compared with well-known analytical and numerical benchmark solutions for the circular annulus geometry and it demonstrated the effectiveness of the MQ-RFM for solving the convective heat-transfer problem in the TA’s cavity. The use of solution structures allows one to take a relatively small number of expansion terms to achieve an appropriate accuracy of the approximate solution satisfying at the same time the given boundary conditions exactly. The application of the MQ-RFM gives the possibility to obtain semi-analytical solutions to the diffusion-convection problems and to identify the main thermal characteristics of the TA, that allows one to improve the device performance.
Yield, Agronomic and Forage Quality Traits of Different Quinoa (Chenopodium quinoa Willd.) Genotypes in Northeast China

Quinoa (Chenopodium quinoa Willd.) grain is well known as a source of nutritious human food, but the nutritional properties of quinoa as animal fodder has not been well explored. Fifteen quinoa accessions were assessed for grain and forage yields, and morphological and quality traits during anthesis and grain filling, with the aim of selecting superior genotypes for greater production and quality traits that are well adapted to northeastern China. Variations were significant among the tested genotypes for all traits. The highest grain weight was recorded in Rainbow (27.51 g plant−1), followed by the local Chinese genotypes Longli 3, YY28 and Mengli 1. Correlation analysis revealed a significant positive association of grain yield with branches and a negative association with culm thickness and inflorescence length, whereas more branches and moderate plant height were the main yield components affecting yield. Forage shoot weight was 37.2–81.6 g plant−1, with JQ3 and ZQ1 exhibiting the highest yields. Forage yield was strongly and positively correlated with most of the morphological traits, except plant height, and was negatively associated with chlorophyll content and the fresh/dry matter ratio. Quality traits and the neutral detergent fiber (NDF) and acid detergent fiber (ADF) contents of quinoa were significantly lower than alfalfa (Medicago sativa L.), oats (Avena sativa L.) or Leymus chinensis (Trin.) Tzvel, and the crude protein (CP) content was significantly higher than all three species, reaching above 20%. The saponin content of the whole plant was higher during anthesis than during grain filling. In conclusion, genotypes having more branches and shorter and more compact main inflorescences achieved higher grain yields, whereas genotypes possessing thick stems, more branches and moderate plant height produced more forage. Hence, the results indicate that superior quinoa genotypes have great potential to solve fodder shortages in China.
Associations between Cognitive Outcomes and Emotion Recognition among Preschoolers

The present study intends to address associations between dialectical thinking of 6-7 years old children and their emotional and executive functioning development. Participants were 152 children. One method was used to assess their emotion recognition by facial expression. Executive functioning was assessed in accordance with the Miyake model, which distinguishes three components of that: working memory, cognitive flexibility, and inhibition control. Dialectical thinking was assessed using three techniques aimed at analyzing children's understanding of the principle of cyclicality, ability to identify contradictions and find opposites to phenomena. Also, a number of parents was interviewed using the questionnaire, which allowed for additional analysis of associations between dialectical thinking and demographic variables such as the number of children in families, the level of mother's education and family income level. The results showed that understanding of the cyclicality principle is related to executive functioning. In turn, all three indicators of dialectical thinking were significantly related to emotion recognition. Taken together, these results suggest that dialectical thinking is associated with emotional knowledge and executive functioning in 6-7 years aged children.
Surface electronic structure for various surface preparations of Nb-doped SrTiO3 (001)

High-resolution angle-resolved photoemission spectroscopy (ARPES) was used to study the surface electronic structure of Nb-doped SrTiO3 (STO) single crystals prepared using a variety of surface preparations. ARPES measurements show that simple degreasing with subsequent anneal in vacuum is not an adequate surface preparation of STO, rather, preparations consisting of etching with buffered HF or HCl, and to a lesser extent, simple water leaching resulted in surfaces with much less disorder. A non-dispersing, mid-gap state was found ∼800 meV above the top of the valence band for samples which underwent etching. This mid-gap state is not present for vacuum-annealed and water-leached samples, as well as for STO thin films grown using molecular beam epitaxy. Theoretical modeling using density functional theory suggests that this mid-gap state is not related to the SrO- and TiO2-terminated surfaces, but rather, is due to a partial hydrogenation of the STO surface that occurs during etching.
Displacive Phase Transitions in and Strain Analysis of Fe-Doped CaTiO3 Perovskites at High Temperatures by Neutron Diffraction

Abstract The influence of small amounts of Fe 3+ on the phase transitions of CaTiO 3 perovskite has been studied by means of in situ high-temperature neutron diffraction. The same sequence of phase transitions as observed in CaTiO 3 is shown by both CaTi 0.9 Fe 0.1 O 2.95 and CaTi 0.8 Fe 0.2 O 2.90 perovskites: from orthorhombic Pnma symmetry at room temperature (RT) to cubic Pm 3 m at high temperature, with an intermediate I 4/ mcm tetragonal phase which exists over a temperature range of about 100°C. The two phase boundaries in the temperature vs composition phase diagram of the system CaFe x Ti 1− x O 3− x /2 (0≤ x ≤0.4) decrease in a quasi-linear manner with increasing Fe content up to x =0.2 and then they both drop abruptly to RT. The existence of a second orthorhombic phase ( Cmcm ), which has been postulated for CaTiO 3 , is ruled out in the Fe-doped CaTiO 3 perovskites in view of the behavior of specific diffraction peaks. Strain analysis shows first-order thermodynamic character for the Pnma → I 4/ mcm transition, while the character of the Pm 3 m → I 4/ mcm transition could be second order or tricritical. Shear strains behave more or less classically, as described by order parameter coupling and shear strain/order parameter coupling models. The volume strain has an anomalous coupling with the order parameter components, which appears to be temperature-dependent.
A fast maximum flow algorithm

In 2013, Orlin proved that the max flow problem could be solved in O(nm) time. His algorithm ran in O(nm + m1.94) time, which was the fastest for graphs with fewer than n1.06 arcs. If the graph was not sufficiently sparse, the fastest running time was an algorithm due to King, Rao, and Tarjan. We describe a new variant of the excess scaling algorithm for the max flow problem whose running time strictly dominates the running time of the algorithm by King et al. For graphs in which m = O(nlog n), the running time of our algorithm dominates that of King et al. by a factor of O(loglog n). Moreover, our algorithm achieves this improved performance without reliance on dynamic trees.
A quantum-mechanical ab initio simulation of neutral and charged point defects in alpha-quartz

The ab initio perturbed-cluster approach has been used to simulate a few defects in alpha-quartz: substitutional aluminium at a silicon site, and interstitial lithium or sodium, both in pure quartz and near substitutional aluminium. Results concerning the electronic structure and the energetics of these defects are presented and discussed. The energies associated with the passage of an alkali ion from a general interstitial site in quartz to one near an aluminium impurity are in reasonable agreement with those resulting from a previous shell-model study of the same defects.
Immigration and Crime in the Local News: Exploring the Macrolevel Covariates of Coverage and Framing

ABSTRACT Contrary to empirical evidence, immigration is seen as increasing rates of crime among the public. However, most people draw from secondary sources—including local news media—to form such opinions. We examine the contextual factors impacting whether and how local media describe the immigration–crime nexus. Using data constructed from content analysis of over 3,800 news articles, we find that the likelihood of local media providing coverage of immigration and crime varies as a function of the violent crime rate, minority population size and growth, and religious and political conservatism. Additionally, news “frames” depend on contextual factors too: Articles in more affluent communities with growing minority populations link immigration to higher rates of crime but are less likely to discuss the protective effects of immigration or immigrant refugees.
The Unbearable Lightness of Academic Fraud: Portuguese Higher Education Students’ Perceptions

The perception that academic fraud is widespread in higher education affects the credibility of higher education schools, giving rise to doubts concerning the quality of learning and the students’ preparation for their professional life. Academic misconduct is presently a common research area. However, higher education schools still seem unable to contain academic fraud, given its prevalence and scope. Therefore, understanding students’ perceptions and attitudes remains critical for schools to define effective policies in promoting and defending academic integrity. Towards that aim, the results from a set of focus groups of students from a higher education school are presented. Students do not link academic fraud with unethical professional behaviour, propose more sanctions for those who commit academic fraud, and consider that certain evaluation methods favour unethical behaviour.
Antimicrobials and Antibiotic-Resistant Bacteria: A Risk to the Environment and to Public Health

The release of antibiotics to the environment, and the consequences of the presence of persistent antimicrobial residues in ecosystems, have been the subject of numerous studies in all parts of the world. The overuse and misuse of antibiotics is a common global phenomenon, which substantially increases the levels of antibiotics in the environment and the rates of their spread. Today, it can be said with certainty that the mass production and use of antibiotics for purposes other than medical treatment has an impact on both the environment and human health. This review aims to track the pathways of the environmental distribution of antimicrobials and identify the biological effects of their subinhibitory concentration in different environmental compartments; it also assesses the associated public health risk and government policy interventions needed to ensure the effectiveness of existing antimicrobials. The recent surge in interest in this issue has been driven by the dramatic increase in the number of infections caused by drug-resistant bacteria worldwide. Our study is in line with the global One Health approach.
Absorptive Routines and the Economic Impact of Incremental Innovations: Developing Continuous Improvement Strategies

The important influence that incremental innovation has, both on the organization’s results and on the development of disruptive innovations in a synergistic relationship of positive sum, makes it necessary to deepen its study. In the context of absorptive capacity, this paper aims to contribute to the construction of a specific model of routines for more efficient exploitation. The empirical study was carried out in a sample of Spanish manufacturing companies of the PITEC Panel. The results show the superiority of the market as a source of knowledge compared to other sources with more complex knowledge, but not adjusted to the needs of a minor improvement. In addition, the management of external knowledge is a process whose phases are interrelated, so the routines and resources used must contribute to enriching the external knowledge previously acquired and not be redundant. Therefore, that would mean an inefficient allocation of resources for obtaining and exploiting continuous innovation.
Assessment of the prognostic value of interim fluorodeoxyglucose positron emission tomography/computed tomography in nasal-type extranodal natural killer/T-cell lymphoma.

Background The prognostic value of interim positron emission tomography/computed tomography (PET/CT) for nasal-type extranodal natural killer/T-cell lymphoma (ENKTL) is controversial. We evaluated the prognostic value of interim PET/CT in ENKTL patients to facilitate risk stratification and guide clinical treatment. Methods Patients with ENKTL who received first-line chemotherapy based on L-asparaginase/pegaspargase with/without involved-field radiotherapy were recruited for this study. Pretreatment and interim PET/CT evaluations were performed. Interim PET/CT was evaluated via the maximum standardized uptake value (SUVmax) and the Deauville 5-point scale (DS); and the capacity to predict progression-free survival (PFS) and overall survival (OS) was evaluated. Receiver operating characteristic (ROC) curves were used to determine the optimal SUVmax cutoff. Fisher's exact test was used to analyze relationships between interim PET/CT results and clinical characteristics. Univariate and multivariate analyses were performed to examine the independent effects of interim PET/CT. The Cochran-Mantel-Haenszel test was used to assess the prognostic value of interim PET/CT at different timepoints. Results Overall, 129 ENKTL patients were enrolled. The optimal interim PET/CT SUVmax cut-off was 4.95. The median follow-up was 34 [2-90] months, in the low SUVmax group (≤4.95), the 2-year PFS and OS rates were 76.3% and 88.0%, respectively; in the high SUVmax group (>4.95), the PFS and OS rates were 15.6% and 44.5%, respectively. Likewise, for the DS 1-3 group, the PFS and OS rates were 78.9% and 91.2%, respectively; and in the DS 4 or 5 group, the rates of PFS and OS were 49.7% and 69.0%, respectively. In univariate analysis, interim PET/CT evaluation based on SUVmax and DS scores were both PFS and OS predictors. In multivariate analysis, SUVmax was independently significantly associated with PFS (P<0.001) and OS (P=0.002), and DS was independently significantly associated with PFS (P=0.004) but not OS (P=0.204). In the Cochran-Mantel-Haenszel testing, the SUVmax and DS were significantly associated with PFS and OS after adjustments for the interim PET/CT timing. Conclusions Interim PET/CT was of prognostic value concerning ENKTL. The SUVmax is an independent prognostic indicator of PFS and OS, while the DS is an independent prognostic indicator of PFS but not OS. The SUVmax is of greater prognostic value than DS.
