PURPOSE This study evaluates the extent to which bilingual children produce the same or overlapping responses on tasks assessing semantic skills in each of their languages and whether classification analysis based on monolingual or conceptual scoring can accurately classify the semantic development of typically developing (TD) bilingual children. METHOD In Study 1, 55 TD children (ages 4;0 [y...

This paper analyzes the impact of biased beliefs on the structure of informational equilibria in classical self-selection models. Using the intuitive insurance market example of Rothschild-Stiglitz (1976) I show that biases of high-risk individuals have fundamentally different effects on equilibrium contracts than biases of low-risk individuals. Whereas equilibrium contracts of both groups are ...

INTRODUCTION Suicide is one of the most prominent problems in health care system in current Iran. It could be impacted by various factors such as social, economic, individual and so on. Researchers show that socio-economic factors and suicide has significantly related. The people in low social class may more engage with social problems than higher social class. They may confront to problems suc...

Through joined two sensitive methods solvation and cloud point extraction separated and determined micro amount of Ce(III) from aqueous solutions by using organic reagent 2,4-Dimethyl pentan-3-one (2,4-DMP) as extractant and non-ionic surfactant 1% TritonX-100 , the experimental study shows the solvation species of Ce+3 extracted into cloud point layer (CPL) have a wavelength for maximum absorb...

Following publication of our article [1], we found errors in analyses performed by the corresponding author (DJS) related to the phylogenetic relationship between Xylella species and the other xanthomonads. These errors do not make any difference to the main findings and conclusions reported in our paper. For example, the phylogenetic positions of NCPPB1131, NCPPB1132 and NCPPB4393 within the G...

Ni-based single crystal (SX) superalloy with low specific weight is vital for developing aero engines a high strength-to-weight ratio. Based on an alloy system 3 wt.% Re but without W, namely Ni-Co-Cr-Mo-Ta-Re-Al-Ti, below 8.4 g/cm3 has been achieved. To reveal the relationship among composition, mechanical properties, and thermal stability of SX superalloys, SXs desirable microstructures are f...

The new species is a member of an apparently monophyletic group within the genus that includes R. flexile, R. walga, R. himanturi, R. burgeri, R. euzeti, R. hawaiiensis, R. urobatidium, R. paratrygoni, R. ditesticulum, R. tetralobatum, R. margaritense, R. biorchidum, and R. spinicephalum. All of these species have bothridia with medial longitudinal septa, a constriction at mid-bothridium, and, ...

A new set of perovskite-like Bi4-xNdxTi3O12 (x=0.1, 0.3, 0.5, 0.7) oxides were synthesized by the method high-temperature solid-phase reaction at temperatures 1000 and 1050°C. X-ray diffraction study showed that these compounds are single-phase have structure Aurivillius phases (AP) family with parameters close to orthorhombic unit cell corresponding space group B2cb (41). The microstructure wa...
