Early cognitive predictors of PISA reading in children with and without family risk for dyslexia
2018
Abstract This study examined language skills and pre-literacy skills (phonological awareness, rapid naming, and letter knowledge) before school-age as predictors of PISA reading at age 15 in two groups of children, with (n = 88) and without (n = 70) family-risk for dyslexia . Moreover, effects of family-risk on these early predictors, reading fluency , and PISA reading were examined while controlling the effect of gender. Children were followed from age 2 to 15. Family-risk had a significant effect on early language and pre-literacy skills, reading fluency and PISA reading. A similar model predicting PISA reading fitted the data well in the Family-risk and the No family-risk group. Languag…
Somatic complaints, emotional awareness and maladjustment in schoolchildren
2015
Introduction: Somatic complaints are common in childhood. Research has shown their relationship with emotional awareness and maladjustment. The study had three objectives: 1) to analyse the prevalence of somatic complaints; 2) to explore the relationships between the variables evaluated: somatic complaints, differentiating emotions, verbal sharing of emotions, not hiding emotions, body awareness, attending to others’ emotions, analysis of emotions, and personal, social, family, and school maladjustments; and 3) to identify predictors of somatic complaints. Patients and methods: The study included a total of 1134 randomly selected schoolchildren of both sexes between 10 and 12 years old (M =…
Conciencia emocional, estados de ánimo e indicadores de ajuste individual y social en niños de 8-12 años
2014
La conciencia emocional o experiencia consciente de la emoción es un concepto clave relacionado con diferentes indicadores de ajuste individual del menor, como las quejas somáticas. Esta relación, mediatizada por los estados de ánimo, se ha demostrado en población preadolescente y adolescente. Sin embargo, apenas se ha analizado en franjas de edad más bajas e incluyendo otros indicadores de ajuste social, como la adaptación. Por ello, el objetivo de este trabajo es el de analizar la contribución de la conciencia emocional y los estados de ánimo, sobre diferentes indicadores de ajuste individual (quejas somáticas) y social (inadaptación evaluada a través del test TAMAI), en niños de 8-12 año…
Sociālo mediju lomas analīze "LEGO" zīmolēšanā
2021
Šī pētījuma mērķis ir izpētīt, kā sociālos medijus var izmantot zīmolu veidošanas vajadzībām, kas būtu bijis jāņem vērā, izmantojot sociālos medijus zīmola veidošanas nolūkos, un izpētīt sociālo mediju ietekmi uz uzņēmuma “Lego” zīmola atpazīstamību. Pētījuma teorētiskajā aspektā tiek aplūkotas un apskatītas tēmas, kas saistītas ar zīmolu, sociālo mediju un visbeidzot sociālo mediju zīmolu veidošanu. Autore izmantoja primāro pieeju un izveidoja tiešsaistes anketu, kurā autore apkopoja datu analīzi. Kvantitatīva klientu aptauja starp Artel uzņēmuma Taškentā mārketinga aģentiem sastāv no pētījuma empīriskās daļas. Atzinumi liecina, ka sociālo mediju kopējā zīmola nozīme un tā ietekme uz zīmol…
Social network brand visibility (SNBV) : Conceptualization and empirical evidence
2018
Social media has become a new way of life that allows for real-time interaction among businesses (B2B) and consumers (P2P/C2C) as well as between business firms and consumers (B2C). Customers are increasingly accessing and using social networking sites (SNS), making it imperative for businesses and organizations to have a presence on these platforms to enhance visibility. The main purpose of this chapter is to provoke an agenda on the study of social network brand visibility (SNBV). We developed and proposed a definition of SNBV and report findings from a preliminary study. We further discuss implications for theory, research, and practice as well as the limitations and options for future r…
Small solar system bodies as granular systems
2017
Asteroids and other Small Solar System Bodies (SSSBs) are currently of great scientific and even industrial interest. Asteroids exist as the permanent record of the formation of the Solar System and therefore hold many clues to its understanding as a whole, as well as insights into the formation of planetary bodies. Additionally, SSSBs are being investigated in the context of impact risks for the Earth, space situational awareness and their possible industrial exploitation (asteroid mining). In all these aspects, the knowledge of the geophysical characteristics of SSSB surface and internal structure are of great importance. Given their size, constitution, and the evidence that many SSSBs ar…
Host–guest complexes of conformationally flexible C-hexyl-2-bromoresorcinarene and aromatic N-oxides: solid-state, solution and computational studies
2018
Host–guest complexes of C-hexyl-2-bromoresorcinarene (BrC6) with twelve potential aromatic N-oxide guests were studied using single crystal X-ray diffraction analysis and 1H NMR spectroscopy. In the solid state, of the nine obtained X-ray crystal structures, eight were consistent with the formation of BrC6-N-oxide endo complexes. The lone exception was from the association between 4-phenylpyridine N-oxide and BrC6, in that case the host forms a self-inclusion complex. BrC6, as opposed to more rigid previously studied C-ethyl-2-bromoresorcinarene and C-propyl-2-bromoresorcinarene, undergoes remarkable cavity conformational changes to host different N-oxide guests through C–H···π(host) intera…
Virtual Reality Based Simulators for Neurosurgeons - What We Have and What We Hope to Have in the Nearest Future
2018
High levels of manual skills, good visual-motor coordination, excel‐lent imagination and spatial awareness are the main factors determining the success of neurosurgeons. Proficiency in neurosurgical skills used to be acquired through hands-on training in cadaver labs and in real operating theatres under master neurosurgeon supervision. Most recently, virtual reality (VR) and augmented reality (AR) computer simulations have also been considered as tools for education in the neurosurgical training. The authors review existing solutions and present their own concept of a simulator which could become the useful tool for planning, simulation and training of a specific neurosurgical procedure usi…
Land Surface Temperature
2019
Abstract An introduction to the chapter on Land Surface Temperature (LST). The basic thermal infrared theory is presented with example algorithms for the retrieval of LST and emissivity data are described in the later section. Various methods to validate satellite Land Surface Temperature (LST) products exist, but the most accurate and conclusive method is the direct comparison against in situ LST obtained from spatially representative radiance measurements over homogeneous sites. Some validation results and insights found in the literature are provided and the determination of in situ emissivity and LST with thermal infrared field radiometers is explained. The chapter concludes with an exa…
Stepwise synthesis and selective dimerisation of bis- and trisloop tetra-urea calix[4]arenes.
2008
Tetra-urea calix[4]arenes substituted with four mono- or bisalkenyl residues have been converted into bis- or tetraloop compounds by intramolecular olefin metathesis, with use of a tetratosylurea calix[4]arene as template. The same strategy has now been used to synthesise trisloop compounds and bisloop compounds with adjacent loops, completing the series of the loop-containing tetra-urea derivatives. A tetra-urea calix[4]arene of the AABB type, where A stands for a bisalkenyl- and B for a monoalkenyl-substituted urea unit, was used as precursor for the three loops. It was easily synthesised from a tetraamino calix[4]arene in which two adjacent amino groups were Boc-protected. The ABCB-type …
