Machine Learning: An Overview and Applications in Pharmacogenetics.
2021
This narrative review aims to provide an overview of the main Machine Learning (ML) techniques and their applications in pharmacogenetics (such as antidepressant, anti-cancer and warfarin drugs) over the past 10 years. ML deals with the study, the design and the development of algorithms that give computers capability to learn without being explicitly programmed. ML is a sub-field of artificial intelligence, and to date, it has demonstrated satisfactory performance on a wide range of tasks in biomedicine. According to the final goal, ML can be defined as Supervised (SML) or as Unsupervised (UML). SML techniques are applied when prediction is the focus of the research. On the other hand, UML…
Elaboration of a Critical Paradigm for Interpreting Modern Architecture: The Almost Intangible Essence of Luigi Moretti's Casa del Balilla at Trecate
2021
Modern architecture is not, from a lexical point of view, uniquely definable. The heterogeneity of the twentieth century heritage is therefore a collective wealth that should be protected from the risk of falling into oblivion. In order to avoid this, it could prove fundamental to establish a process of the knowledge of these assets. This should not, however, result in a simple and passive recording of architectural facts: a deep understanding of the complexity of modern architecture, which has as its objective the protection of buildings, could be obtained, for example, through a real and proper decoding of signs, conducted by a critical use of the metalanguage most congenial to the archit…
Computer Simulation Paradigm Regarding the Structure and Mechanical Characteristics of Human Long Bones
2013
Given the complex form of the long bones, a quality method of geometrical modeling which provides a good result is that of the 3D modeling by reconstruction, using the principles of reverse engineering. One of the important problems that shall be taken into consideration while modeling is the one concerning the real structure of the bones. This aspect presents a lot of importance because from the point of view of the mechanical behavior, the bones are neither homogenate structures. In this paper a study of the long bones structures is undergone, and in relation to the modelated element (the human tibia) it is divided in areas (called constructive-anatomical entities) of different mechanical…
Mental Account Barriers and Transaction Purpose: A Romanian Point of View
2013
Abstract The present study encompasses the behavioral model of decision making. Using the models provided by scientific literature, the relationship between the basic structure of mental accounts, transaction utility and consumer decision, together with perceived comfortability. The procedure was carried out using undergraduate students of Lucian Blaga University of Sibiu, with similar proportions of sexes and with resembling ages. Results have shown that influence of mental accounting structuring and transaction utility on decision and perceived comfortability is insignificant, taken into account the differences between sexes. The presented results bring knowledge into the economic behavio…
Investigating Some Construct Validity Threats to TALIS 2018 Teacher Job Satisfaction Scale: Implications for Social Science Researchers and Practitio…
2020
The credibility of findings ensuing from cross-sectional survey research depends largely on the validity and reliability of the research instruments. Critical attention to the quality of such instruments will ensure logical and valid results. The purpose of this article is to provide evidence for two methodological issues observed that are potential threats to construct validity of widely used Teaching and Learning International Survey (TALIS) 2018 data on teacher job satisfaction scale (TJSS). The first issue concerns reverse recoding of some items necessary to obtain a coherence covariance between these items and other items on the same subscale. The second issue concerns the addition of …
An Analysis of the Internal Organization of Facebook Groups
2019
With the rapid development and growth of online social networks (OSNs), researchers have been pushed forward to improve the knowledge of these complex networks by analyzing several aspects, such as the types of social media, the structural properties of the network, or the interaction patterns among users. In particular, a relevant effort has been devoted to the study and identification of cohesive groups of users in OSNs (also referred as communities) because they are the basic building block of each OSN. While several research works on groups in OSNs have mainly focused on identifying the types of groups and the contents created by their members, the analysis of internal organizations of …
Digital Technologies for virtual recomposition. The case study of Serpotta stuccoes.
2014
The matter that lies beneath the smooth and shining surface of stuccoes of the Serpotta family, who used to work in Sicily from 1670 to 1730, has been thoroughly studied in previous papers, disclosing the deep, even if empirical, knowledge of materials science that guided the artists in creating their masterworks. In this work the attention is focused on the solid perspective and on the scenographic sculpture by Giacomo Serpotta, who is acknowledged as the leading exponent of the School. The study deals with some particular works of the artist, the so-called “teatrini” (Toy Theater), made by him for the San Lorenzo Oratory in Palermo. On the basis of archive documents and previous analogica…
Bullying in Students Who Stutter: The Role of the Quality of the Student–Teacher Relationship and Student’s Social Status in the Peer Group
2020
Children who stutter are at risk of being excluded, rejected, or bullied at school because of their impairment. The aim of the current research is to assess the relationship between students and te...
Determinants of user behaviour and recommendation in social networks
2014
Purpose – The purpose of this paper is to analyse the determinants of social network use behaviour using Theory of Planned Behaviour (TPB) and Uses and Gratifications Theory. Design/methodology/approach – A quantitative study was carried out with data gathered by personal interview using a structured questionnaire. Relationships proposed in the theoretical model were estimated through structural equation models. In total, 811 users of social networks over 14 and residents in Spain were part of the sample. Findings – Results indicate that use attitude and the subjective norm, both TPB variables, directly and significantly influence social network loyalty. Thus, network loyalty can be achiev…
Psychometric properties of the Spanish version of the Temporal Satisfaction with Life Scale (TSLS): A study on elderly attending to university progra…
2015
Several measures have been developed for the operalization of well-being, standing out the Satisfaction With Life Scale (SWLS). To cope with some of its problems the Temporal Satisfaction with Life Scale (TSLS) was developed. The aim of this study is to present and validate the Spanish version of the TSLS, in a sample elderly attending to University programs. The sample was composed of 737 elderly. Together with the TSLS, an indicator of general life satisfaction and the SF-8 Health Scale were used. Analyses included the study of factorial validity, estimations of reliability and external validity. Results of the confirmatory factor analysis were adequate: χ2(87)=454.593 (p<.001), CFI=.9…
