Indoor air pollution is a recognized emerging threat, claiming millions of lives annually. People are constantly exposed to ambient and indoor air pollution. The latest research shows that people in developed countries spend up to 90% of their time indoors and almost 70% at home. Although impaired IAQ represents a significant health risk, it affect...

Background Infantile nephropathic cystinosis (INC) is a rare lysosomal storage disorder, mostly and often firstly affecting the kidneys, together with impaired disharmonious growth and rickets, eventually resulting in progressive chronic kidney disease (CKD). With the introduction of cysteamine therapy, most pediatric patients reach adulthood with...

The paper presents a simpler and more precise model of lumbar moment prediction based on single linear, or multiple linear regression with two predictors. The body mass index (BMI) as the predictor contains two of the most important static anthropometric measures, height and mass, whose separated role in lumbar moment prediction, as well as their m...

This review covers peer-reviewed publications about free time of school-aged children and youth in Croatia, published since 1990. We briefly present these publications and extract their common points. Based on that, we suggest possible addition to leisure time activities of school-aged children and youth.

BACKGROUND: Inconsistent findings on coupled illumination, accumulated noise and task complexity effects on cognitive-motor performance asked for a more comprehensive analysis by focusing on performance dynamics. OBJECTIVE: The aim was to investigate the effects of illumination, accumulated noise, and task complexity on several average and non-aver...

Horizontal curves are locations on the road network with a high road accident risk. In order to provide drivers with timely and proper information about the upcoming curve, road authorities often use chevron signs. Although the main design of chevrons is similar in most countries (one colour for the background and another for the arrow), the combin...

Cognitive abilities of blind and partially sighted children have been understudied in Croatia, and there is very little research on it. Since working memory plays quite an important role in cognitive functioning, the goal of this research was to explore the status of working memory in blind and partially sighted Croatian adolescents. To do so, 195...

The intellectual status of blind and partially sighted children in Croatia has not been systematically researched for almost three decades, despite the change in assessment instruments and institutional support forms. The aim of the research was twofold: (1) to elucidate how developmental, health, and social support factors determine the choice of...

We present three studies which investigated the relations between cognition and personality from 7 to 20 years of age. All three studies showed that general cognitive ability and the general factor of personality are significantly related throughout this age span. This relation was expressed in several ways across studies. The first investigated de...

Research that focuses on aging process of selective attention (SA) functioning dynamics is very rare, especially regarding the professional drivers’ population. Given the fact that the consequences of SA functioning in railroad engineers are extremely high for traffic safety, we considered it important to investigate the aging effects on three indi...

Integration/differentiation of mental processes is major mechanism of development. Developmental theories ascribe intellectual development to it. In psychometric theory, Spearman’s law of diminishing returns postulates that increasing g allows increasing differentiation of cognitive abilities, because increased mental power allows variable investme...

Spearman's hypothesis tested at the level of items states that differences between ethnic groups on the items of an IQ test are a function of the g loadings of these items, such that there are small differences between groups on items with low g loadings and large differences between groups on items with high g loadings, and it has been confirmed i...

This paper focuses on the incidence, socio-demographic, psychological and psychiatric profiles of missing persons, as well as on the reporting and searching for missing persons. The sample used in the study included 1,724 cases of missing persons reported to the police between 2010 and 2012, representing 34.2% of the total number of reported missin...

The intention of this chapter is to make a contribution to the overall body of knowledge on the missing persons phenomenon. This study is a part of a larger study conducted for the first time in the Republic of Croatia. It focuses on the incidence, socio-demographic, psychological and psychiatric profiles of missing persons, as well as on the repor...

Purpose: To explore the importance and existence of Croatian police managers' relevant characteristics from the perspective of police officers, and in relation to several police officers' demographic and professional characteristics. Design/Methods/Approach: A convenience sample of 132 Croatian police officers (104 males) who attended a study progr...

We present a study which investigated the inter-relations between processing speed, attention control, working memory, fluid intelligence, and mathematical reasoning from 7 to 18 years of age. To fulfil this aim, 478 participants drawn from each of the age years 7-17 years at first testing were examined twice, separated by a 12-month interval. Seve...

Despite the relevant findings on non-average information processing rate (IPR) indicators-intelligence relation, and on age-related changes of some of these indicators during aging, the research on sex-specific age-related changes of these indicators during childhood and adolescence are lacking. In a transversal study, 1197 school children (598 gir...

A developmental research of the relationship between the Big-Five and speed of information processing (SIP) was conducted with the aim of considering the personality-intelligence relationship. Personality dimensions were assessed by International Personality Item Pool (IPIP) questionnaire, while SIP and related test errors (Er-SIP) were assessed by...

The objectives of the study were: (1) to give an overview of a less known developmental-psychological method of measuring quantitative-relational (Q-R) thought and it's psychometric validation on a Croatian sample of children and adolescents; (2) to investigate hypotheses on developmental specificities of Q-R thought derived from a Three-level theo...

The aim of this study was a systematic analysis of the relationship between speed of information processing (SIP), reading comprehension and school achievement in three school subjects among pupils in lower grades of primary school.

Design/methodology/approach The concept is developed in a thorough analysis of strengths and weaknesses of existing approaches, and in thorough contrasting the proposed solutions w...

Speed of human information processing (SIP) is a research construct which has been examined under different names and with different intensity for more than sixty years. Its importance is briefly described in four research fields: differential, experimental, aging and cognitive development. Since SIP presents an important component of contemporary...

We investigated cognitive-motor abilities in 303 (156 female) school children from Zagreb, Croatia, in the age span 10 to 14 years using a newly developed chronometrical reactionmeter system (CRD). The following tests were applied: CRD-311 (simple visual discrimination of signal location), CRD-324 (short-term memory actualisation), CRD-21 (simple c...

Certain statistical aspects of social systems are described by appropriately defined quantities named social potentials. Relations between social potentials are postulated by drawing an analogy with thermodynamics relations between thermodynamic potentials, thus obtaining a toy model of some of the statistical properties of social systems. Within t...
