The impact of healthy lifestyles on academic achievement among Italian adolescents
2021
AbstractWe evaluated the association between healthy lifestyles and academic achievement in a sample of 373 adolescent Italian students. Specifically, we investigated on the association between use of illegal drugs, habits to practice a regular physical, typology of diet, levels of social support, levels of self-esteem, level of Internet use, perceived stress and amount of sleep and academic achievement. Academic performance was positively correlated with good diet, perceived social support, and self-esteem. A statistically significant difference emerged between students with high versus low correct grade point averages in relation to lifetime and current use of illegal drugs. Last, academi…
Using the Breeder genetic algorithm to optimize a multiple regression analysis model used in prediction of the mesiodistal width of unerupted teeth
2014
For the prediction of the unerupted canine and premolars mesiodistal size, have been proposed different variants of multiple linear regression equations (MLRE). These are based on the amount of the upper and lower permanent incisors with a tooth of the lateral support. Aim of present study was to develop a method for optimization of MLRE, using a genetic algorithm for determining a set of coefficients that minimizes the prediction error for the sum of permanent premolars and canines dimensions from a group of young people in an area Romania's central city represented by Sibiu. To test the proposed method, we used a multiple linear regression equation derived from the estimation method propo…
Satisfaction with the clinical practice among nursing students using regression models and qualitative comparative analysis
2020
Abstract Background Clinical practice is considered fundamental in nursing studies for the effective education of nurses and students' satisfaction. Both the clinical environment and the clinical educator are key factors in students´ satisfaction. Objectives To analyze the influence of the socio-demographic variables of clinical educators and nursing students on satisfaction with the clinical practice. Design This was an observational, cross-sectional study. Settings A clinical practice course at a private university in Valencia, Spain. Participants The study included 527 nursing students enrolled on the clinical practice, supervised by 187 clinical educators. Methods Two statistical method…
Relationship between Perception and Socio-Economic Characteristics of Culture Community in the Development of Marine Ecotourism in Nusmapi Island
2021
Marine tourism is a type of special interest tourism, namely by managing and utilizing marine and coastal landscapes, both those that are managed directly such as swimming, boating, snorkeling, diving, or indirectly such as picnics and beach sports. Nusmapi Island has the potential to be developed as a marine tourism object which has the potential for waters and coral reefs that are in good condition. The purpose of this study was to determine the relationship between the level of public perception and the socio-economic conditions of the local community on Nusmapi Island. In October-November 2020 this research was carried out on Nusmapi Island, Manokwari Regency. The descriptive explorator…
The Perception and Attitudes Towards City Garbage Management: A First Analysis
2017
The main aim of this paper is to to explore the perception and attitude of people toward an important issue like the City Garbage Management. A new Survey Questionnaire to measure the perception and attitudes towards city garbage management has been developed by the Authors, in order to realize a very first analysis of compatibility of the Comprehensive Action Determination Model - CADM (Klöckner, 2013) with City Garbage Management issues. To test the application of the CADM model to City Garbage Management, a simple linear regression was calculated to predict the dependent variables based on predictor variables according the CADM model. The linear regression analysis shows a first confirma…
Impact of COVID-19 pandemic on mobility in ten countries and associated perceived risk for all transport modes.
2021
The restrictive measures implemented in response to the COVID-19 pandemic have triggered sudden massive changes to travel behaviors of people all around the world. This study examines the individual mobility patterns for all transport modes (walk, bicycle, motorcycle, car driven alone, car driven in company, bus, subway, tram, train, airplane) before and during the restrictions adopted in ten countries on six continents: Australia, Brazil, China, Ghana, India, Iran, Italy, Norway, South Africa and the United States. This cross-country study also aims at understanding the predictors of protective behaviors related to the transport sector and COVID-19. Findings hinge upon an online survey con…
Modeling a non-stationary bots’ arrival process at an e-commerce Web site
2017
Abstract The paper concerns the issue of modeling and generating a representative Web workload for Web server performance evaluation through simulation experiments. Web traffic analysis has been done from two decades, usually based on Web server log data. However, while the character of the overall Web traffic has been extensively studied and modeled, relatively few studies have been devoted to the analysis of Web traffic generated by Internet robots (Web bots). Moreover, the overwhelming majority of studies concern the traffic on non e-commerce websites. In this paper we address the problem of modeling a realistic arrival process of bots’ requests on an e-commerce Web server. Based on real…
Forecasting Passenger Traffic for a Regional Airport
2019
Abstract The purpose of the present research is estimating the potential traffic for SIA (Sibiu International Airport, SBZ) for the year 2017. Predicting as accurate as possible the passenger traffic for a certain airport is an aspect of major importance for both the airport management and the airline companies. The theoretical quality of the forecasting models for air traffic of passengers is fundamental for obtaining the most accurate predictions. In this regard, a two-step process was used in developing the traffic forecasting model: (1) Identifying the proper regression model for traffic estimation based on the number of aircraft departures, and (2) Forecasting the number of aircraft de…
Attitude Function as a Moderator in Values-Attitudes-Behavior Relations
2011
Abstract The aim of the present study was to find whether attitude functions could be useful in predicting aberrant driving. One of the attitudes functions is to express values; hence, we hypothesized that attitudes whose function is to express values will better predict traffic violations. We explored: (i) values in relation to attitudes towards aberrant driving behavior by regression analysis; (ii) and we explored moderating role of attitude functions in value-attitude-behavior relations. The study sample included 305 respondents who completed self-report questionnaires. Current research confirms previous results and also shows that values do predict attitudes when individual had formed h…
A study on The Factors Affecting Merger and Acquisition Decision In Nepalese Banking Sector
2016
Master's thesis Business Administration BE501 - University of Agder 2016 The main purpose of this study is to find out the factors that would lead to making decision regarding going for merger and acquisition among the banks in Nepalese banking sector. This thesis finds out various factors that would affect merger and acquisition decision in banking sector based upon previous studies, and tries to check whether these are significant in case of Nepalese banking sector or not. Four theories: neo-classical, agency, behavioral and resource dependency; have been taken into consideration for purpose of finding out factors affecting decision to go for merger and acquisition. Based upon the previou…
