Using System Dynamics to Model Student Performance in an Intelligent Tutoring System

2017

One basic adaptation function of an Intelligent Tutoring System (ITS) consists of selecting the most appropriate next task to be offered to the learner. This decision can be based on estimates, such as the expected performance of the student, or the probability that the student successfully solves each particular task. However, the computation of these values is intrinsically difficult, as they may depend on other complex latent variables that also need to be estimated from observable quantities, e.g. the current student's ability. In this work, we have used system dynamics to model learning and predict the student's performance in a given exercise, in an existing ITS that was developed to …

Adaptation of a German Multidimensional Networking Scale into English

2011

Networking refers to building and maintaining personal contacts in order to obtain resources that, in turn, enhance one’s career success and work performance. This study reports the translation and adaptation of a multifaceted German networking scale ( Wolff & Moser, 2006 ) into English and focuses on the equivalence of the two language versions. Going beyond the often used translation-backtranslation method, we used a parallel translation-backtranslation method in combination with two expert committees to arrive at the English scale version, aiming to obtain at least structural equivalence. We utilize a bilingual sample (N = 76) as well as monolingual samples from the US (N = 174) and…

Linking Online Marketing Practices in Romania to Global Trends

2018

The very fast online transformations cause rapid changes in consumers’ behavior and, implicitly, the need for businesses’ adaptation to market trends and wants.

Thus, online marketing is a business culture, an entrepreneurial mindset in all over the world, for each type of business. This paper aims to give an overview on Romanian online advertising market by presenting data, trends, and main players. Many recent studies showed that the online is in a growing process, a…

Contractual satisfaction: drivers and implication for theory

2014

The aim of inter-firm relations is to achieve each firm’s objectives. The achievement of these objectives is reflected in firms’ satisfaction. Satisfaction as a concept can be studied at different levels and contractual relations is one such level. Most studies on inter-firm satisfaction have looked at the general level of satisfaction, whose drivers are complex to account for. This study aims to investigate contractual satisfaction from the perspective of some of its key drivers. The main finding suggests that, while ongoing term specificity, contingent adaptability, reputation and trust have a positive influence on contractual satisfaction, opportunism has a negative one.

Effects of nine months resistance training on cycling economy in elderly men and women

2016

The aging process, along with the lifestyle, is associated with loses in functional capacity and independence due to factors such as decreases in muscle mass, strength, and aerobic capacity, among others. Resistance training (RT) has been shown to induce strength and muscle size gains in the elderly. Improvements in maximal endurance capacity have been shown in some studies, while others have found no change. The purpose of the present study was to examine the effects of RT on the cycling economy in the elderly. A group of 47 older men and women (65-75 years) participated in the study. Subjects were assigned into one of two groups: 1) a training group performing 3 months of RT focusing on l…

Employability and Job Insecurity:Supporting Individuals to Achieve Career Success in the WhiteWater Environment

2019

El rápido ritmo de la cuarta revolución industrial de hoy, junto con la inestabilidad económica y la competitividad global, han resultado en cambios organizativos generalizados y en una creciente inseguridad laboral. Reconociendo que la inseguridad laboral continuará intensificándose en los años venideros, esta investigación, a través de tres estudios, tiene como objetivo actualizar el papel de la empleabilidad en el éxito profesional subjetivo en el mundo laboral contemporáneo y descubrir las condiciones que pueden impulsar el rendimiento al experimentar inseguridad laboral . El estudio 1 ha demostrado que la empleabilidad sigue siendo un concepto relevante en el mercado laboral actual a p…

Reliability and Validity of The Finnish Version of The Boston Carpal Tunnel Questionnaire among Surgically Treated Carpal Tunnel Syndrome Patients

2019

Background and Aims: The Boston Carpal Tunnel Questionnaire is the most commonly used outcome measure in the assessment of carpal tunnel syndrome. The purpose of this study was to translate the original Boston Carpal Tunnel Questionnaire into Finnish and validate its psychometric properties. Materials and Methods: We translated and culturally adapted the Boston Carpal Tunnel Questionnaire into Finnish. Subsequently, 193 patients completed the Finnish version of the Boston Carpal Tunnel Questionnaire, 6-Item CTS Symptoms Scale, and EuroQol 5 Dimensions 12 months after carpal tunnel release. The Boston Carpal Tunnel Questionnaire was re-administered after a 2-week interval. We calculated cons…

Investigations on the geographical variability of the human transferrins.

1971

On the basis of own and from the widely scattered literature compiled materials the geographical distribution of the transferrin alleles is discussed. They reveal a characteristic distribution pattern, as the slow Tf variants produced by TfD alleles are obviously more frequent in tropical than in non-tropical populations. Considering similar results in cattle and its interpretation by Ashton (1958, 1965), it is hypothesized, that the relatively high TfΓ frequencies in tropical biotops might be a selective adaptation to their special climatic conditions. In this connection an association between slowly moving transferrin proteins in man and tolerance to hotter climates — as could be found in…

Genetic-dependency of peroxisomal cell functions - emerging aspects

2003

This paper reviews aspects concerning the genetic regulation of the expression of the well studied peroxisomal genes including those of fatty acid beta-oxidation enzymes; acyl-CoA oxidase, multifunctional enzyme and thiolase from different tissues and species. An important statement is PPARalpha, which is now long known to be in rodents the key nuclear receptor orchestrating liver peroxisome proliferation and enhanced peroxisomal beta-oxidation, does not appear to control so strongly in man the expression of genes involved in peroxisomal fatty acid beta-oxidation related enzymes. In this respect, the present review strengthens among others the emerging concept that, in the humans, the main …
