Application of molecular topology to the prediction of antifungal activity for a set of dication-substituted carbazoles, furans and benzimidazoles

2003

In this paper, the endpoint is the application of molecular topology to the search of QSAR relations into a group of dicationsubstituted carbazoles, furans and benzimidazoles, all showing antifungal activity against C. albicans. Mathematical and statistical methods such as linear regression and discriminant analysis, are used to goal. The obtained results clearly show a high efficiency of the formalism on the prediction and classification of antifungal activity. 83% of the compounds showing MIC , 10 mg/ml (active group) are correctly classified, whilst 100% overall accuracy is achieved for those compounds showing MIC . 100 mg/ml (inactive group). q 2003 Elsevier Science B.V.

Comparison of Physical Activity and Sedentary Behaviour between Schoolchildren with Cystic Fibrosis and Healthy Controls: A Gender Analysis

2021

The purpose of this study was to examine differences in sports participation and the levels of physical activity (PA) and sedentary behaviour (SB) between schoolchildren with cystic fibrosis (CF) and a healthy control group (CG) taking into account the gender variable. PA and SB were measured with an accelerometer for 7 consecutive days in 44 children (24 girls

Lobbying on Accounting Standards: Evidence from IFRS 2 on Share-Based Payments

2012

Lobbying is an essential part of the International Accounting Standards Board (IASB) standard-setting process. There is still much to learn, however, about key aspects of the roles played and arguments employed by various constituents when lobbying practices do occur. This paper focuses on the regulation of share-based payments. As these transactions were under-regulated before International Financial Reporting Standard (IFRS) 2, we expect that the strong debate that occurred during the 1990s resulted in conflicting opinions when this standard was under discussion. To analyse lobbying behaviour and assess its influence on the IASB's decision-making, we conducted a content analysis of 539 le…

Introduction: Despite substantial interest in the development of health behaviors, there is limited research that has examined the longitudinal relationship between physical activity (PA) and smoking trajectories from youth to adulthood in a Finnish population. This study aimed to identify trajectories of smoking and PA for males and females, and study the relationship between these trajectories from youth to adulthood. Methods: Latent profile analysis (LPA) was used to identify trajectories of smoking and PA separately for males and females among 3355 Finnish adults (52.1% females). Participants’ smoking and PA were assessed five to eight times over a 31-year period (3–18 years old at the …

Longitudinal physical activity trajectories from childhood to adulthood and their determinants: The Young Finns Study

2018

Determining lifelong physical activity (PA) trajectories and their determinants is essential to promote a physically active lifestyle throughout the life-course. We aimed to identify PA trajectories from childhood to midlife and their determinants in a longitudinal population-based cohort. This study is a part of the Cardiovascular Risk in Young Finns Study. From 1980, a population-based cohort (N = 3596; 1764 boys/1832 girls, age 3-18 years) has been followed up for 31 years. PA indices were formed based on self-reported data (between age 9-49 years) on frequency, duration, and intensity of leisure (during childhood) or high-intensity (at later age) PA and on sports club participation/comp…

Accelerated internationalisation: evidence from a late investor country

2006

PurposeRecent studies are trying to adapt the explanation of the internationalisation process to new environmental conditions. This paper aims to offer evidence of the existence of a group of firms that use a speeded‐up internationalisation process.Design/methodology/approachCluster analysis and logit regressions are used on a sample of 271 Spanish export firms.FindingsThe results obtained support the claim that substantial differences do exist between fast and gradual internationalising firms. The firms included in the more international active group are characterised by: a proactive attitude on the part of managers with regard to internationalisation activities, a strategy based on market…

Repercussions of Evolutionism in the Spanish Natural History Society

2001

In 1871, during the markedly libe ral environment created by the Sexennial Revolution (1868-1874), the Spanish Natural History Society (SEHN) was founded) It was established at the instigation of an active group of naturalists whose primary objectives were to promote the study of Natural History in Spain, discuss the most relevant problems relating to this discipline, and have a vehicle through which to publish their work. This early initiative was highly successful, with the number of members in the first three decades fluctuating between 290-300 and, in some years, exceeding four hundred. University professors and teachers from the Faculties of Science, Medicine and Pharmacy; researchers …

How the Psychology of Education Contributes to Research With a Social Impact on the Education of Students With Special Needs: The Case of Successful …

2020

One current challenge in the psychology of education is identifying the teaching strategies and learning contexts that best contribute to the learning of all students, especially those whose individual characteristics make their learning process more difficult, as is the case for students with special needs. One main theory in the psychology of education is the sociocultural approach to learning, which highlights the key role of interaction in children's learning. In the case of students with disabilities, this interactive understanding of learning is aligned with a social model of disability, which looks beyond individual students' limitations or potentialities and focuses on contextual as…
