Meta-analysis of the relationship between teachers’ self-efficacy and attitudes toward inclusive education

2022

Abstract This meta-study aims to examine the size of the relationship between teachers' self-efficacy and attitudes toward inclusive education of K-12 students with special educational needs and to identify potential moderators (publication, sample, and research procedure characteristics). We synthesized the research conducted from 1994 to 2018, and 41 studies were included. Bare-bones meta-analysis with random effect model revealed a sample size weighted correlation coefficient between teachers’ self-efficacy and attitudes as r ¯  = 0.35 (CI = 0.31-0.39). The between-study variations were not associated with hypothesized publication and sample characteristics. However, the self-efficacy me…

A correction method for dynamic analysis of linear continuous systems

2005

A method to improve the dynamic response analysis of continuous classically damped linear system is proposed. As in fact usually, following a classical approach, a reduced number of eigenfunctions are accounted for and the response is evaluated by integrating the uncoupled differential equations of motion in modal space, neglecting the contribution of high frequency modes (truncation procedure). Here, starting from the given system, it is proposed to set up two differential equations governing the motion of two new continuous systems: the first one contains only the first m non-zero eigenvalues of the given system and the second one contains the remainder non-zero infinity - m eigenvalues. …

On WQO Property for Different Quasi Orderings of the Set of Permutations

2013

The property of certain sets being well quasi ordered (WQO) has several useful applications in computer science – it can be used to prove the existence of efficient algorithms and also in certain cases to prove that a specific algorithm terminates.

A Posteriori Methods

1998

A posteriori methods could also be called methods for generating Pareto optimal solutions. After the Pareto optimal set (or a part of it) has been generated, it is presented to the decision maker, who selects the most preferred among the alternatives. The inconveniences here are that the generation process is usually computationally expensive and sometimes in part, at least, difficult. On the other hand, it is hard for the decision maker to select from a large set of alternatives. One more important question is how to present or display the alternatives to the decision maker in an effective way. The working order in these methods is: 1) analyst, 2) decision maker.

Toward solutions for energy efficiency

2020

Abstract The tariff setting for district heating (DH) services is a hard regulatory procedure. This chapter is devoted to development of the simple but sufficiently accurate methodology for fast and objective evaluation of the actual costs of DH to optimize the regulatory process and to set adequate tariffs on heat production and transmission. The developed methodology is based on the data sets of Latvian DH providers, but the methodological principles are applicable in another area too. Investigation of heat production drivers and following simulation revealed the key performance indicators (KPIs): fuel type and price. By usage of intelligent benchmarking data mining methods and mathematic…

Assessing preferences of some predefined consumer profiles for attributes of small fruit

2015

Small fruit (commonly referred to as berries), represents a potential high-value niche-market crop in Italy. This fruit grows naturally in many localities of northern Italy, but favorable environmental conditions for this crop can be found also in southern regions where this production may support local farmers' incomes. According to literature and to official statistics, small fruit's health benefiting properties are well known in the international market, but little is known about the reason of a low commercialization rate of fresh small fruit in Italy. The objective of this study was to assess, in the domestic market, consumer preferences for small fruit according to consumer rankings ap…

Women of wine in Sicily: analysis of their role, motivation and work

2012

Recent surveys on female employment show that, in Italy, the number of Women Entrepreneurs has constantly increased. This work aims to study the "Women of Wine" in Sicily, those entrepreneurs or managers who hold leadership and decision-making roles within the wineries, focusing on age, qualification, type of activity, motivations that led to undertake the task, difficulties encountered, and also on changes made by women in the firm. By calculating the coefficient of contingency we intended to measure the association between some factors of development of women-run wineries in Sicily, namely between professional characteristics of women managers deemed most important for this investigation,…

Forze di attrito e determinazione del coefficiente di attrito statico

2013

Esperimento per la misura del coefficiente di attrito dinamico con il metodo energetico.

2013

In questo articolo presenterò una proposta didattica laboratoriale che avrà per oggetto la misura del coefficiente di attrito dinamico fra due superfici, sfruttando il teorema lavoro-energia cinetica. Particolare attenzione sarà posta sulle problematiche tecniche e concettuali che stanno alla base di questa attività di laboratorio e sulla sua spendibilità in ambito scolastico.

Characterization of wastewater and biomass activity in a membrane bioreactor using respirometric techniques

2010

Over the last two decades, Membrane Bioreactors (MBRs) emerged even more for wastewater treatment, ensuring high removal efficiencies as well as very small footprint required. Indeed, in this kind of process, a modification in biomass activity and viability can exist compared to that of a conventional activated sludge (CAS) process. In this context, respirometric analysis represents a reliable tool in order to evaluate the actual biomass kinetic parameters, to insert in mathematical models in the design phase, as well as to monitor the biomass viability, especially when these processes are operated with high sludge retention time (SRT) values. The paper presents some results of respirometri…
