Employers’ Needs and Expectations for Qualified Employees (Case Study on the Opinions in One of the Regions in Latvia)
2015
Abstract Qualified, loyal and motivated employees are highly demanded by employers and business promoters. The paper deals with employers’ needs and expectations for qualified and loyal employees, and investigates cooperation of employers, educators and municipalities. The following methods were used: analysis of scientific publications; focus group discussions; surveys of employers, teaching staff, students and graduates of VEI. For survey data analysis descriptive statistical analysis, non-parametric statistical test of Kruskal-Wallis and factor analysis were applied. The main findings indicate that besides professional skills and competence, social competence, motivation to work and resp…
Prevalence of lip lesions in an Indian population
2014
Objectives: Lip lesions are a frequent cause of consultation in dentistry, as they comprise a signifi cant proportion of the oral lesions. The aim of the present study was to identify the different lip lesions and determine their prevalence in an Indian population. Material and methods: 5231 patients visiting a Department of Oral Medicine and Radiology were examined for the presence of different lip lesions during the period from October, 2011 to May, 2013. The statistical analysis was done using Chi-square test and p<0.05 was considered to be statistically signifi cant. Results: The age of the patients ranged from 8-70 years with a mean age of 32.6 years. The prevalence of lip lesions was …
Elementary school teachers adapt their instructional support according to students' academic skills – A variable and person-oriented approach
2015
This study examined the longitudinal associations between children’s academic skills and the instructional support teachers gave individual students. A total of 253 Finnish children were tested on reading and math skills twice in the first grade and once in the second grade. The teachers of these children rated the instructional support that they gave each child in reading and mathematics. The results showed that the poorer the student’s reading and math skills were, the more support and attention the student received from his or her teacher later on. However, instructional support did not contribute positively to the subsequent development of the students’ academic skills. The person-orie…
Use of electronic nose to determine defect percentage in oils. Comparison with sensory panel results
2010
Abstract An electronic nose based on an array of 6 metal oxide semiconductor sensors was used, jointly with linear discriminant analysis (LDA) and artificial neural network (ANN) method, to classify oils containing the five typical virgin olive oil (VOO) sensory defects (fusty, mouldy, muddy, rancid and winey). For this purpose, these defects, available as single standards of the International Olive Council, were added to refined sunflower oil. According to the LDA models and the ANN method, the defected samples were correctly classified. On the other hand, the electronic nose data was used to predict the defect percentage added to sunflower oil using multiple linear regression models. All …
Frequency Change Patterns across Proficiency Levels in Japanese EFL Learner Speech
2014
This study investigated the overall patterns of variation across seven oral proficiency levels of 1,263 Japanese EFL learners and native English speakers. The methodological approach combined a learner corpus, language processing techniques, and multivariate statistical analyses to identify patterns of language use. The largest spoken learner corpus in Japan, the National Institute of Information and Communications Technology Japanese Learner English (NICT JLE) Corpus was used for the analysis. This corpus consists of transcribed interviews with 1,281 learners and contains over one million running words of spoken English. The transcriptions were compared with data gathered from 20 native En…

Search for anisotropic gravitational-wave backgrounds using data from Advanced LIGO and Advanced Virgo's first three observing runs
2021
We report results from searches for anisotropic stochastic gravitational-wave backgrounds using data from the first three observing runs of the Advanced LIGO and Advanced Virgo detectors. For the first time, we include Virgo data in our analysis and run our search with a new efficient pipeline called {\tt PyStoch} on data folded over one sidereal day. We use gravitational-wave radiometry (broadband and narrow band) to produce sky maps of stochastic gravitational-wave backgrounds and to search for gravitational waves from point sources. A spherical harmonic decomposition method is employed to look for gravitational-wave emission from spatially-extended sources. Neither technique found eviden…

Review of Particle Physics
2020
The Review summarizes much of particle physics and cosmology. Using data from previous editions, plus 2,143 new measurements from 709 papers, we list, evaluate, and average measured properties of gauge bosons and the recently discovered Higgs boson, leptons, quarks, mesons, and baryons. We summarize searches for hypothetical particles such as supersymmetric particles, heavy bosons, axions, dark photons, etc. Particle properties and search limits are listed in Summary Tables. We give numerous tables, figures, formulae, and reviews of topics such as Higgs Boson Physics, Supersymmetry, Grand Unified Theories, Neutrino Mixing, Dark Energy, Dark Matter, Cosmology, Particle Detectors, Colliders, …
Identifying Finnish Children’s Impulsivity Trajectories From Kindergarten to Grade 4: Associations With Academic and Socioemotional Development
2015
Research Findings: The purpose of this study was to identify the developmental trajectories of impulsive behavior among 378 Finnish children who were followed from kindergarten to fourth grade. In addition to ratings of children’s impulsivity, the analyses included measures of motivation, cognitive skills, socio-emotional adjustment, and teacher–student relationship. Four latent groups were identified that differed in the level and change of the children’s impulsive behavior across time: first, a group with low impulsivity; second, a group with decreasing impulsivity; third, a group with moderate impulsivity; and, fourth, a small group with a contradictory trajectory showing an upward trend…
