Migration Flows in Finland: Regional Differences in Migration Determinants and Migrant Types

2003

The present study analyzes interregional migration flows in Finland during 1985-96 using a large sample from the longitudinal census data file. The regional concentration of population has sped up in recent years, and most migrants now head to five urban growth centers. The empirical analysis reveals that it is particularly the human capital component (young, educated individuals) that moves to, and stays in, the growth centers. They are attracted by the higher expected wages and employment chances. Conversely, some individuals, mainly older and less educated ones, move back to their original home regions. This countermovement reduces the speed of population concentration. Declining region…

Assessment of Organizational Trust: Preliminary Data for Romanian Adaptation of the Organizational Trust Inventory Short Form

2013

Abstract In the last years, trust became an important variable in regard to the well-being of organizations. In Romania, it was included in studies as a variable but there are few instruments that measure organizational trust. Therefore I identify a necessity for developing instruments useful in assessing and promoting any organizational adjustments. This paper presents the preliminary data obtained in the process of adaptation of OTI for the Romanian population. In doing so, we followed the guidelines of ITC. Using a sample of 108 employees the psychometric results show that OTI-RO has a high level of internal consistency reliability (a = 0.94) and it can be used exclusive for equivalent p…

A two-point boundary value formulation of a mean-field crowd-averse game

2014

Abstract We consider a population of “crowd-averse” dynamic agents controlling their states towards regions of low density. This represents a typical dissensus behavior in opinion dynamics. Assuming a quadratic density distribution, we first introduce a mean-field game formulation of the problem, and then we turn the game into a two-point boundary value problem. Such a result has a value in that it turns a set of coupled partial differential equations into ordinary differential equations.

The Trier Inventory for Chronic Stress (TICS), consisting of 57 items, is an instrument for measuring chronic stress in nine areas. There is also a short form (SSCS) of the TICS consisting of 12 items. However, this 12-item short form does not include all nine areas of the theoretical model and the long version. Therefore, a short version including all nine scales/areas was investigated. The TICS was taken by a sample of N = 2,473 respondents from the general population, aged 14 to 99, selected by random-route sampling. Confirmatory factor analyses applying robust maximum likelihood estimations (MLM) tested the model fit. The one-factor-model proposed by the original authors was tested, and…

Anthropological investigation of a Kurdish village population from south-eastern Turkey. I. Regional comparison of morphological features

1988

The paper is dealing with an anthropological investigation of a Kurdish village population from southern Turkey. We especially attached importance on the complete registration of all inhabitants to get a reliable sample for regional comparison of morphological features. Anthropological data of other Kurdish population groups are used for univariate and multivariate analysis. The resulting clusters are discussed beside the question of representation under the standpoint of regional and cultural origin of the samples.

La inteligencia de los niños

2005

Partial results of an investigation are presented whose primary objective is to adapt and to standardize the neurocognitive assessment battery C.A.S. of Das and Naglieri (1997) in a child sample. The test is an operationalization of a non traditional intelligence model (PASS) that considers the intelligent behaviors as a group of four cognitive basic processes (planning, attention, simultaneous and successive processing). The objectives of this work are to obtain the psychometric properties of the instrument and also, to analyze if differences exist according to sex and age. The study type is crosswise - transactional. It was administered the CAS to 150 children residents in Buenos Aires am…

Testing international dental maturation scoring system and population-specific Demirjian versions on Saudi sub-population

2013

Objectives: The purpose of this study was to test the applicability of the Demirjian method and revised versions for estimating chronological age (CA) from dental age (DA) in a sample of children. Study Design: A sample of 252 individuals of known age (4 to 14 yrs), sex (males: 125, females: 127), and ethnicity (Saudi) was collected. Each individual was aged using the original Demirjian method and revised versions, including Saudi, Kuwaiti, Belgian, and revised international curves. The differences between dental age and chronological age were analyzed using paired sample t-tests with Bonferroni corrections and multinomial regression tests at the 0.05 level of significance. Results: The res…

Validation of the F-DBQ: A short (and accurate) risky driving behavior questionnaire for long-haul professional drivers

2021

Abstract Although the Driving Behavior Questionnaire (DBQ) remains the most known tool for assessing risky road behaviors among motor vehicle drivers, recent studies have raised several concerns on the specificity of both driving task conditions and behavioral repertory of certain segments of the driving population. Among them, long-haul (cargo) professional drivers constitute one of the “intensive driving” groups for which the existing adapted behavioral research tools are still very scarce. Purpose The aim of the present study was to test and validate the F-DBQ (or “Freight Driving Behavior Questionnaire”), a short version of the DBQ adapted to the occupational driving conditions and typi…

The Tax Justice Network-Africa v Cabinet Secretary for National Treasury & 2 Others: A Big Win for Tax Justice Activism?

2019

This paper develops an optimization model for selecting a large subsample that improves the representativeness of a simple random sample previously obtained from a population larger than the population of interest. The problem formulation involves convex mixed-integer nonlinear programming (convex MINLP) and is therefore NP-hard. However, the solution is found by maximizing the “constant of proportionality” – in other words, maximizing the size of the subsample taken from a stratified random sample with proportional allocation – and restricting it to a p-value high enough to achieve a good fit to the population of interest using Pearson’s chi-square goodness-of-fit test. The beauty of the m…

Method effects associated with negative worded items in the 29 items spanish version of Ryff's Well-being Scales

2018

Aim Although they have been frequently used in the literature, there has been much confusion concerning Ryff’s Well-being Scales, such as their factor structure and the effects of method due to the use of reversed items. A common practice nowadays is the use of positively worded items and reversed forms, in order to reduce response bias. However, in many different studies have been seen that this practice introduce method effects in the scores, leading to problems of reliability and validity. This work had two goals: first, to verify the factor structure of the 29-item Spanish version of the original Ryff’s Well-being Scale in an athlete population, and second, to determine whether the meth…
