Measuring Cognitive Reflection without Maths: Development and Validation fo the Verbal Cognitive Reflection Test
The Cognitive Reflection Test (CRT) became popular for its impressive power to predict how well people reason and make decisions. Despite the popularity of the CRT, a major issue complicates its interpretation: the numerical nature of the CRT confounds reflection ability with mathematical ability. We have addressed this issue by developing the Verbal CRT (CRT-V), a novel 10-item measure of cognitive reflection (https://osf.io/xehbv/), using non-mathematical problems with good statistical and psychometric properties and with low familiarity. First, we selected suitable items with relatively low familiarity and optimal difficulty as identified in two different populations (Studies 1 and 2) and with high content validity as judged by an expert panel (Study 3). Second, we demonstrated good criterion and construct validity for the test in different populations with a wide range of variables (Studies 4-6, 8) and a good internal consistency and test-retest reliability (Study 7). The Verbal CRT was less associated with math anxiety, objective and subjective numeracy than the original CRT and it was test equivalent across gender, age groups and administration setting. In contrast with the original CRT (Hedge’s g = 0.29, 95% CI[0.17, 0.40]), the Verbal CRT showed no gender differences (Hedge’s g = -0.06, 95% CI[-0.18, 0.06]). The Verbal CRT can complement existing, numerical, tests of cognitive reflection
ЗАКОНОДАТЕЛЬНОЕ ОБЕСПЕЧЕНИЕ СЕМЕНОВОДСТВА ОВОЩНЫХ КУЛЬТУР В РОССИЙСКОЙ ФЕДЕРАЦИИ (ПО МАТЕРИАЛАМ ПАРЛАМЕНТСКИХ СЛУШАНИЙ 11 ИЮЛЯ 2017 ГОДА)
The analysis of the national seed market state really showed the high dependence of Russian food security on imported seeds. The government means for supporting the national seed production program undertaken in 2015 by Ministry of Agriculture of RF were very effective and took action as showed the data from ‘Roselkhozcentre’. Thus, the total land area used for seed production in vegetables, melons and gourds was increased by 48% that amounted to 2104.3 ha in 2016, and that was more than in 2015. Moreover, the vegetable and melon seed producers and breeders are worried about the facts of falsification and low quality. The main reason of occurrence of such seeds that are not meeting the variety requirements in the market is an insufficient legislative system and its lack of correspondence to the current seed production, conditions and up-to-date requirements. It is necessary to take urgent measures to revise the current state of legislative system in national seed production program. Анализ состояния отечественного рынка семян данных культур показывает действительно высокую зависимость продовольственной безопасности России от импорта семян. Меры государственной поддержки семеноводства, предпринятые МСХ РФ в 2015 году, оказались актуальными, и как показывают данные ФГБУ «Россельхозцентр», начали давать свои первые результаты: в 2016 году, по сравнению с 2015 годом, отмечено увеличение площадей под семеноводством овощебахчевых культур на 48%, и они составили 2104,3 га. Вместе с тем, авторов сортов, производителей семян, имеющих отношение не только к семенам овощебахчевых культур, все больше беспокоят факты фальсификации семян и, прежде всего, их сортовых качеств. Причиной появления на рынке семян, не отвечающих сортовым требованиям, является несовершенство законодательства и его несоответствие требованиям отрасли и времени. Необходимо принятие безотлагательных мер по исправлению создавшейся ситуации в семеноводстве.

Non-Gaussian generalization of the Kazantsev-Kraichnan model
We consider a natural generalization of the Kazantsev-Kraichnan model for
small-scale turbulent dynamo. This generalization takes account of statistical
time asymmetry of a turbulent flow, and, thus, allows to describe velocity
fields with energy cascade. For three-dimensional velocity field, generalized
Kazantsev equation is derived, and evolution of the second order magnetic field
correlator is investigated for large but finite magnetic Prandtl numbers. It is
shown that as , the growth increment tends to the limit known
from the T-exponential (Lagrangian deformation) method. Magnetic field
generation is shown to be weaker than that in the Gaussian velocity field for
any direction of the energy cascade, and depends essentially on the Prandtl
number.Comment: 6 figures, 1 tabl
Temperamental Constellations and School Readiness: A MultiVariate Approach
This study uses canonical correlation analyses to explore the relationship between mul- tiple predictors of school readiness (i.e., academic readiness, social readiness, and teacher-child relationship) and multiple temperamental traits using data from the second wave (age 54 months, n = 1226) of the longitudinal Study of Early Child Care and Youth Development (SECCYD; NICHD ECCRN 1993). This longitudinal study collected data on a large cohort of children and their families from birth through age 15. For academic readiness, only one temperamental constellation emerged, representing the construct of effortful control (i.e., high attentional focusing, high inhibitory con- trol). For peer interactions, two significant constellations emerged: “dysregulated” (low inhibitory control, low shyness, and high activity), and “withdrawn” (high shyness, low inhibitory control, low attentional focusing). Finally, the analyses exploring child-teacher relationships revealed two significant constellations: “highly surgent” (high activity, low inhibitory control, low shyness) and “emotionally controlled” (low anger/frustration and high inhibitory control). Results of this study form a more nuanced exploration of relationships between temperamental traits and indicators of school readiness than can be found in the extant literature, and will provide the groundwork for future research to test specific hypotheses related to the effect temperamental constellations have on children’s school readiness

Modulated Crystalline-B Phases in Liquid Crystals
Detailed x-ray scattering studies of the modulated phases of 4-n-heptyloxybenzylidene-4-n-heptylaniline (7O.7) are reported. In addition to the previously identified one-dimensional modulation that appears at the transition from the crystalline-B (CrB) phase with AB AB stacking to the CrB phase with orthorhombic stacking, there are two other modulation structures each of which contains two noncolinear modulations. The modulations are explained in terms of a phenomenological model in which domains are separated by walls for which the intralayer packing is identical to the lower-temperature crystalline-G phase. This model yields the measured values for both the modulation wave vector and the lattice distortion.Engineering and Applied Science
Generation of small-scale structures in the developed turbulence
The Navier-Stokes equation for incompressible liquid is considered in the
limit of infinitely large Reynolds number. It is assumed that the flow
instability leads to generation of steady-state large-scale pulsations. The
excitation and evolution of the small-scale turbulence is investigated. It is
shown that the developed small-scale pulsations are intermittent. The maximal
amplitude of the vorticity fluctuations is reached along the vortex filaments.
Basing on the obtained solution, the pair correlation function in the limit
is calculated. It is shown that the function obeys the Kolmogorov law
