Effect of intercropping on the morphological and nutritional properties of carrots and onions in organic agriculture

A trial involving intercropped and pure stands of carrots 'Nantes' and onions 'Kupusinski jabucar' was conducted on a certified organic farm in Futog. The yield, morphological and nutritional properties of the crops analyzed were determined in the study. Furthermore, the biological efficiency of intercropping was assessed using the relative yield (RYT) and the land use efficiency index (LER). The mixture of crops had influenced the morphological properties examined. In both experimental plant species, the nutritional properties of onions and carrots exhibited a higher content of dry matter (DM) in the double-row growing system without maize gluten meal (onions - 11.42 %, carrots - 10.45 %) compared to single crops. The highest content of β-carotene was determined by alternating single rows of onions and carrots in a plot without the use of gluten (68.94 μg/g DM). The relative yield and the land use efficiency index have shown that there is a biological efficiency of combining carrots and onion as the values obtained are higher than 1. Carrots and black onions are favorable for intercropping because they are complementary, thus interactively contribute to increasing the yield per unit area and improving the nutritional properties.
The relationship between regulatory focus and learning engagement among Chinese adolescents

Abstract Regulatory focus may shape the manner in which students perceive and respond to learning environments and then further influence their attitudes and behaviors. In the current study, 1487 adolescents in China were surveyed to illuminate the relationship between regulatory focus and learning engagement. The results showed that promotion focus was a positive predictor of learning engagement, whereas prevention focus was a negative predictor. Both academic self-efficacy and depression mediated the relationship between the two foci and learning engagement. Moreover, five regulatory focus profiles identified by adopting a person-centered approach were found to relate to academic self-efficacy, depression, and learning engagement in various ways. Compared with other profiles, the one with high promotion focus and low prevention focus showed higher academic self-efficacy and lower depression and, in turn, demonstrated greater learning engagement, suggesting that such a profile may be the most beneficial for adolescent development.

“My Eyes Have Been Opened”: Pre-Service Secondary Teachers Exploring Behavior Management through a Microteaching Project

ABSTRACT One of the primary concerns of pre-service secondary teachers is negotiating student behavior and classroom management, and novice teachers cite this as one of the reasons why they leave the profession in the first three years. This study examines the learning outcomes of a microteaching project with a student behavior component. The participants were 79 pre-service secondary teachers enrolled in four sections of a general methods and assessment course. Participants engaged in a two-and-a-half-week microteaching project in which they were confronted with various behavior disruptions during their teaching as their classmates became “high school students. ” The results show that the participants gained a deeper understanding of the complexity of teaching and student behavior and also identified strategies to take with them into their future classrooms.
Entrepreneurial attitudes : a distinction between two professional groups

This study investigates discrimant ability of the Entrepreneurial Attitude Orientations Scale of 365 individuals practicing in two mutually exclusive professions (pharmacists N = 200 and accountants N = 175) on the profiles of Holland’s hexagon of occupational groups. Anova was performed with the EAOS sub-and total scales as dependent variables and entrepreneurial and non-entrepreneurial profiles as independent variables. Some discriminance by means of Tukey’s Range Test and interaction through LS-means was found between the two professions and employment status of individuals. Implications for management are indicated. *To whom all correspondence should be addressed.
The Impact of Intellectual Capital On Profitability, Productivity And Market Valuation: Evidence From Iranian High Knowledge-Based Industries

This study investigates the impact of intellectual capital (IC) on firms’ performance indices, namely, profitability, productivity, and market valuation in the listed companies at Tehran Stock Exchange. Data were obtained from a sample of 69 firms in high knowledge-base industries from 2001 to 2008. In order to measure the intellectual capital index, we have used Value Added Intellectual Coefficient (VAICTM). Multiple linear regression was applied to analyze and test research hypotheses. The findings suggest that the performance of a firm’s intellectual capital can explain its profitability and productivity, but not market valuation. The findings of the study reveal that there are positive relationships between firms’ size, leverage and physical capital intensity, and their profitability and productivity. However, the results also show that, except for firms’ size, there aren’t significant associations of these factors with market valuation. The findings propose that managers can raise firm’s performance by designing a plan to enhance intellectual capital, such as the plan of improving human capital performance by training and educating or employing new intellectual capital.
Metric and Scale Design as Choice Architecture Tools

Interest is increasing in using behavioral decision insights to design better product labels. A specific policy target is the fuel economy label, which policy makers can use to encourage reduction in carbon dioxide emissions from transport-related fossil-fuel combustion. In two online experiments, the authors examine whether vehicle preferences can be shifted toward more fuel-efficient vehicles by manipulating the metric (consumption of gas vs. cost of gas) and scale (100 miles vs. 15,000 miles vs. 100,000 miles) on which fuel economy information is expressed. They find that preference for fuel-efficient vehicles is highest when fuel economy is expressed in terms of the cost of gas over 100,000 miles, regardless of whether the vehicle pays for its higher price in gas savings. The authors discuss the underlying psychological mechanisms for this finding, including compatibility, anchoring, and familiarity effects, and conclude that policy makers should initiate programs that communicate fuel-efficiency information in terms of costs over an expanded, lifetime scale.
Achievement Motivation And Emotional Intelligence As Predictors Of Mathematical Resilience Among Secondary School Students

This study investigated achievement motivation and emotional intelligence as predictors of Mathematical resilience among senior secondary school students in Rivers Nigeria. Two research questions were answered and two hypotheses were tested at 0.05 alpha level. The population of the study comprised all 24,727 senior secondary school (SS2) students in the 247 public secondary schools in Rivers State. Sample size of 1690 was obtained using 20% of the population in simple random sampling technique. Three self-designed non-cognitive instruments titled Achievement Motivation Scale” (AMS), “Emotional Intelligence Scale” (EIS) and “Mathematical Resilience Scale” (MRS) were used for data collection. The AMS contained 14 items; EIS contained 17 items while MRS contained 20 items respectively. Face and content validities were carried out by the researchers along with three other experts in test, measurement and evaluation. The Cronbach reliability coefficient of 0.75, 0.72 and 0.77 were obtained for AMS, EIS and MRS respectively. Linear and multiple regressions were used to answer the research questions while t-test and ANOVA associated with linear and multiple regressions were used to test the null hypotheses. It was found among others that achievement motivation significantly predicted mathematical resilience. Emotional intelligence and achievement motivation jointly and significantly predicted mathematical resilience. It was recommended among others that guidance counselors should help students to reshape their minds from fixed to growth mindsets in order to become mathematical compliant as opposed to mathematical anxious.
AMD-stability in the presence of first-order mean motion resonances

The angular momentum deficit (AMD)-stability criterion allows to discriminate between a priori stable planetary systems and systems for which the stability is not granted and needs further investigations. AMD-stability is based on the conservation of the AMD in the averaged system at all orders of averaging. While the AMD criterion is rigorous, the conservation of the AMD is only granted in absence of mean-motion resonances (MMR). Here we extend the AMD-stability criterion to take into account mean-motion resonances, and more specifically the overlap of first-order MMR. If the MMR islands overlap, the system will experience generalized chaos leading to instability. The Hamiltonian of two massive planets on coplanar quasi-circular orbits can be reduced to an integrable one degree of freedom problem for period ratios close to a first-order MMR. We use the reduced Hamiltonian to derive a new overlap criterion for first-order MMR. This stability criterion unifies the previous criteria proposed in the literature and admits the criteria obtained for initially circular and eccentric orbits as limit cases. We then improve the definition of AMD-stability to take into account the short term chaos generated by MMR overlap. We analyze the outcome of this improved definition of AMD-stability on selected multi-planet systems from the Extrasolar Planets Encyclopaedia.
Framing Matters in Gender-Paired Dictator Games

We show that social context matters in gender-paired dictator decisions. Our experiment investigates the influence of gender-pairing and framing on monetary transfers in a 2x2x2 design where sender gender, recipient gender, and frame, i.e. give or take, are varied. We are the first to combine all three variables and uncover that giving information about the gender of the recipient accommodates framing effects. If each of the three manipulated variables were to be analyzed independently, our data would confirm previous findings where females transfer more than males and framing has no effect (Eckel and Grossman, 1998; Dreber et al., 2013). However, we investigate the manipulated variables in interaction and find that framing matters when information about recipient gender is salient. For both genders, transfers in opposite-sex pairs are always higher than in same-sex pairs, but signicantly higher in the take frame. We thus suggest that the gender composition of the sample, gender-pairing, or beliefs about the counterpart's gender should be controlled for in experiments testing gender differences in social interaction.
Displacement characteristics of coarse fluvial bed sediment

Previous work highlights the need for data collection to identify appropriate models for temporal evolution of tracer dispersal in rivers. Results of 64 gravel‐bed field tracer experiments covering a wide range of flow and sediment supply regimes are compiled here to determine the probabilistic character of gravel transport. We focus on whether particle travel distances and waits are thin‐ or heavy‐tailed. While heavy‐tailed travel distance distributions are observed between successive monitoring events in different hydrological and sediment supply regimes, heavy‐tailedness does not persist through total travel distance over multiple monitoring events, suggesting that individual monitoring events occur before particle travel distance exceeds the characteristic correlation length for the channel (such that particles that start in fast paths remain in fast paths and particles in slow paths remain in slow paths). After a large number of transport events, super‐diffusive spreading was not observed at any of the gravel bed streams. Continuous‐time tracking of x, y, z coordinates of tracers in natural streams is necessary to capture exact step and waiting time distributions.
A UNIFIED LENSE–THIRRING PRECESSION MODEL FOR OPTICAL AND X-RAY QUASI-PERIODIC OSCILLATIONS IN BLACK HOLE BINARIES

Recent observations of accreting black holes reveal the presence of quasi-periodic oscillations (QPO) in the optical power density spectra. The corresponding oscillation periods match those found in X-rays, implying a common origin. Among the numerous suggested X-ray QPO mechanisms, some may also work in the optical. However, their relevance to the broadband—optical through X-ray—spectral properties have not been investigated. For the first time, we discuss the QPO mechanism in the context of the self-consistent spectral model. We propose that the QPOs are produced by Lense–Thirring precession of the hot accretion flow, whose outer parts radiate in optical wavelengths. At the same time, its innermost parts are emitting X-rays, which explains the observed connection of QPO periods. We predict that the X-ray and optical QPOs should be either in phase or shifted by half a period, depending on the observer position. We investigate the QPO harmonic content and find that the variability amplitudes at the fundamental frequency are larger in the optical, while the X-rays are expected to have strong harmonics. We then discuss the QPO spectral dependence and compare the expectations to the existing data.
An Early Ostrich Dinosaur and Implications for Ornithomimosaur Phylogeny

Abstract A new ornithomimosaur from the Yixian Formation of Liaoning Province People's Republic of China is described. These beds are near the Jurassic-Cretaceous boundary. This specimen is interesting because it has several primitive characters for ornithomimosaurs such as teeth and a short first metacarpal. This taxon is placed in a phylogenetic analysis of Coelurosauria and shown to be near the base of the ornithomimosaur clade. Using this phylogeny we comment on the biogeographic history of this group.
Gravity wave characteristics in the middle atmosphere derived from the Empirical Mode Decomposition method

The recently developed Empirical Mode Decomposition (EMD) method is applied to analyzing gravity wave characteristics in the middle atmosphere. By establishing a close connection between the fundamental Intrinsic Mode Functions (IMFs) derived from the EMD method and WKB solutions of a dispersive-dissipative wave equation, we show that the EMD method can provide useful insights into physical processes in the middle atmosphere where dispersive-dissipative wave phenomena are dominant. A local power spectrum function P is introduced which provides a quantitative description of the spectrum at any particular location within a data series. The sharp localization of P in space and wavenumber leads to an identification of unphysical small scale oscillations by falling spheres embedded in the wind profiles above 60 km. Further analyses of the horizontal wind profiles derived from the Dynamics Adapted Network for the Atmosphere (DYANA) campaign suggest that for horizontal wind fluctuations with vertical wavenumber m≤3 km−1 (or vertical wavelength Lz≥2 km) the previously observed m−3 Fourier spectra could be produced by a linear wave packet whose characteristic vertical wavenumber decreases with altitude. For small vertical scale disturbances with m>3 km−1 (Lz<2 km) a near −3 slope in the marginal distribution exists locally in the middle atmosphere with a great degree of universality, suggesting that nonlinear energy cascade processes may dominate the spectral formation in this wavenumber range.
Guideline to Different Aspects of Assessment in Alzheimer’s Disease Patient

Alzheimer’s disease (AD) is the leading cause of dementia in the USA and worldwide. In this article, we have discussed the incidence of dementia, especially Alzheimer's disease dementia, and its familial association, according to the latest reports. There is a menu of instruments discovered in past decades for the behavioral, cognitive and functional assessment of an AD person. Behave-AD, E-BEHAVE-AD, E-BEHAVE-AD FW, Neuropsychiatric inventory are discussed in detail, in view of the researches conducted in their context. Global deterioration scale (GDS), Brief cognitive rating scale (BCRS), Mini-mental state exam (MMSE), Functioning and self-care (FAST) and other tools are used in the cognitive and functional assessment of an AD person. We threw light on the pros and cons of utilization of these divergent tools.
Mean Shift Segmentation Assessment for Individual Forest Tree Delineation from Airborne Lidar Data

Airborne lidar has been widely used for forest characterization to facilitate forest ecological and management studies. With the availability of increasingly higher point density, individual tree delineation (ITD) from airborne lidar point clouds has become a popular yet challenging topic, due to the complexity and diversity of forests. One important step of ITD is segmentation, for which various methodologies have been studied. Among them, a long proven image segmentation method, mean shift, has been applied directly onto 3D points, and has shown promising results. However, there are variations among those who implemented the algorithm in terms of the kernel shape, adaptiveness and weighting. This paper provides a detailed assessment of the mean shift algorithm for the segmentation of airborne lidar data, and the effect of crown top detection upon the validation of segmentation results. The results from three different datasets revealed that a crown-shaped kernel consistently generates better results (up to 7 percent) than other variants, whereas weighting and adaptiveness do not warrant improvements.
MODIS Image-derived ice surface temperature assessment in the Southern Patagonian Icefield

Ice surface temperature (IST) is one of the most relevant parameters when it comes to estimating the effects of climate change on glaciers. This study aims to estimate the IST for the Southern Patagonian Icefield (SPI) during the 2001–2016 period and, in so doing, to contribute to the assessment of the MOD11A1 product in this area. We evaluated IST performance by comparing it with that of automatic weather stations (AWSs). In addition, the glaciological significance of the results is presented through 1) IST trends, 2) annual IST anomalies, 3) IST behavior at different altitudes and orientations and 4) a comparison with Santa Cruz River flow records. The correlation coefficients obtained between the IST and AWSs ranged between 0.66 and 0.85. In addition, we report on the mean absolute differences between them, ranging between 0.6 ± 3.6°C and 9.4 ± 1.9°C. In this sense, we observed the lowest differences at the AWSs that were located in a homogeneous environment. Stated in glaciological terms: 1) only 1% of the pixels had a statically significant IST trend (p-value ≤ 0.05): between 0.01 and 0.05°C/month; 2) we found that most of the IST anomalies ranged between –1 and 1°C throughout the period of this study; 3) the results suggest that the altimetric gradient was the most influential variable of the IST, mostly in north-oriented glaciers; and 4) the SPI IST showed an annual periodicity, which, in turn, shows a high correlation with the Santa Cruz River flow (R = 0.86). This study is the first in estimating the SPI’s IST and contributes to enhance our knowledge of glacier dynamics and, therefore, the management of the water resource. Despite this, some MOD11 filtering is required in regions with high cloud cover frequency.
Frequency effects on spelling in Hebrew-speaking younger and older adults

Abstract Previous research has documented conflicting findings regarding the effect of word frequency on spelling in older adults. The current study examines spelling in Hebrew, in which it is easier to define the type of likely misspellings in each word. Younger and older Hebrew speakers spelled 120 single words that differed in word and letter frequency. Results show that all participants made more phonological substitutions of target letters on low-frequency words and on words with low-frequency letters. Yet, younger adults had a lower percentage of correct responses than did older adults, especially on low-frequency words. Vocabulary knowledge eliminated this age effect. We suggest that aging leads to greater reliance on full lexical retrieval of spelling instead of on sublexical phoneme-to-grapheme processing, due to years of exposure to written language, increase in vocabulary, and consolidation of orthographic representations.
ELVIS: Exploring the Local Volume in Simulations

We introduce a set of high-resolution dissipationless simulations that model the Local Group (LG) in a cosmological context: Exploring the Local Volume in Simulations (ELVIS). The suite contains 48 Galaxy-size haloes, each within high-resolution volumes that span 2–5 Mpc in size, and each resolving thousands of systems with masses below the atomic cooling limit. Half of the ELVIS galaxy haloes are in paired configurations similar to the Milky Way (MW) and M31; the other half are isolated, mass-matched analogues. We find no difference in the abundance or kinematics of substructure within the virial radii of isolated versus paired hosts. On Mpc scales, however, LG-like pairs average almost twice as many companions and the velocity field is kinematically hotter and more complex. We present a refined abundance matching relation between stellar mass and halo mass that reproduces the observed satellite stellar mass functions of the MW and M31 down to the regime where incompleteness is an issue, M_* ∼ 5 × 10^5 M_⊙. Within a larger region spanning approximately 3 Mpc, the same relation predicts that there should be ∼1000 galaxies with M_* > 10^3 M_⊙ awaiting discovery. We show that up to 50 per cent of haloes within 1 Mpc of the MW or M31 could be systems that have previously been within the virial radius of either giant. By associating never accreted haloes with gas-rich dwarfs, we show that there are plausibly 50 undiscovered dwarf galaxies with H i masses >10^5 M_⊙ within the local volume. The radial velocity distribution of these predicted gas-rich dwarfs can be used to inform follow-up searches based on ultracompact high-velocity clouds found in the ALFALFA survey.
Empowering Leadership and Team Creativity: An Examination of Direct and Indirect Path

In this research, we investigated how empowering leadership is related with team level creativity of employees. Integrating theory of group behavior with componential theory of creativity, we found that empowering leadership behavior affects the team level creativity of employees directly and indirectly through the mediation of team learning behavior and team psychological empowerment as team process and team emergent states. For this research we collected data from two sources (Subordinates, and Supervisors) by temporally dividing data collection process into two points in time for independent, dependent, and mediating variables from employees of a bank operating in Pakistan. Preliminary analysis and analysis with mediation and indirect affects performed to check the direct and indirect effects. Mplus 7.0 was used with random model techniques to analyze hypothesized model for employees’ sample (N = 343). Mediation was analyzed using indirect effect of random models and further confirmed the confidence using bootstrapping procedure. Further research findings, implications, and future research directions also discussed in this research.
