Sharing Drawings with Smartphones in the Classroom – Art-Based Education in Social Sciences
2020
This article identifies the factors that indicate the opportunity of reviewing the methods in teaching economics in order to overcome the traditional teaching-learning scheme that overvalues rote learning and find formulas that facilitate the development of analytical skills. On the other hand, this work points out the importance of developing creative competences. One way to do this is to introduce artistic practices in the classroom, even in non-artistic subjects. In this work an experience of education based on the arts is presented. Thanks to smartphone cameras, students can share and project drawings in the classroom immediately to facilitate group learning. The proposal is to represen…
PLAYING WITH THE COLORS-PRE-SCHOOL CHILDREN’S SELF-DIRECTED DRAWING EXPERIANCE
2019
At the pre-scool age, playing is the main key to the child’s way to express them selfs in drawing process. In order to ensure the self-directed drawing, there is a need for the availability of diverse naterials throughout of the day, enabling the child to act and play in accordance with his intentions. In a drawing process, trying out different techniques, tools,mixing colors, trying to discover new ways of expression, observing and imitating other (children’s or adult) actions, provides the basic conditions for meaningful activity of a child. The aim of the thesis is to find out theoretically and practically the essence of self-directed drawing activity of preschool children and possibilit…
Design of the Tube Roll Forming Process Through an Heuristic Algorithm
2002
In the paper the design of an industrial tube roll forming process is developed utilizing an heuristic algorithm, namely the simulated annealing (SA). In particular both the number and the shape of the deforming rolls are determined in order to define the forming sequence. The effectiveness of the results supplied by the SA algorithm is verified both by means of some experiments tests carried out on an industrial tube roll forming equipment and through a set of numerical simulations of the process.
Quality in the consulting service – evaluation and impact: a survey in Spanish firms
2001
The paper deals with the importance of the work of external consultants in firms and of consulting as a function. The study deals with the analysis of external advice within small to medium‐sized enterprises. It tries to reflect the actual importance of external advice sought by firms in trying to reach the highest possible level of client satisfaction. The survey reported in this paper was carried out to evaluate the impact of consulting and to determine the degree of satisfaction of the clients that had used Spanish consulting services. To this end, firms that had used such services were interviewed on‐site. The purpose of the research was to analyse the effects on management processes wi…
Nursing home vouchers in Spain: the Valencian experience
2002
The main purpose of this paper is to evaluate the innovative nursing home voucher scheme that was introduced by the Valencia Autonomous Region of Spain in the early 1990s to implement targets laid down by the national plan for the development of older people's services. The article begins with a review of the evolution of Spanish social services, and especially the nursing home sector, and then summarises the genesis, objectives and characteristics of the voucher scheme. The main part of the paper reports a performance analysis and economic evaluation of the programme. On the basis of detailed information over four years, it is concluded that nursing home vouchers have contributed to the in…
Rubber Forming Processes of Thin Sheets
1999
In the last decade flexible media have been increasingly utilized in sheet metal drawing processes in order to reduce the tooling cost and to improve the product quality. In the present paper an axisymmetric deep drawing process of thin steel sheets is taken into account: in particular a flexible pad is utilized in order to simplify the tooling set. The process mechanics is investigated through numerical simulations and experimental tests with the aim to find out a proper set of operative parameters allowing the stamping of sound components and to highlight the particular deformation path of the drawing cup. The comparison between the numerical predictions and the experimental verification …
Springback Evaluation In Basic Sheet Metal Stamping Processes
2000
In the present paper a measurement technique based on the shadow moire method has been set up in order to evaluate the springback phenomenon in deep drawing operations. Two proper coefficients are introduced to quantitatively describe the effect considered. In particular the proposed technique is able to acquire the final profile of the drawn parts along one or more generatrices, once extracted out from the dies and to compare such profile with the ideal one derived from the dies CAD geometry. The proposed technique has been applied to an axysimmetrical deep drawing operation and moreover the influence of the blankholder force level and of the lubricating conditions have been taken into acc…
An Optical Technique for Springback Measurement in Axisymmetrical Deep Drawing Operations
2001
Abstract In this paper, a measurement technique based on the shadow moire method has been set up to evaluate the springback phenomenon in deep drawing operations. Two proper coefficients are introduced to quantitatively describe the investigated effect. In particular, the proposed technique is able to acquire the final profile of the drawn parts along one or more lateral contour, once extracted out from the dies, and compare such profile with the ideal one derived from the dies CAD geometry. The proposed technique has been applied to an axisymmetrical deep drawing operation, and, moreover, the influence of the blankholder force level and lubricating conditions has been taken into account. T…
Environmental and Forest Planning in Italy: Conflicts and Opportunities
2016
Abstract The necessity of a more sustainable use of lands and environmental resources in general, throughout specific programming and management tools at different scale levels is nowadays widely shared. Forests and woodlands are a key asset of the environment and the traditional and current landscapes. With regards to the state of art of forest planning and management tools in Italy, in this short paper, after a synthetic analysis of the tools currently adopted at different levels, some critical aspects of the relationships of forest planning instruments with other planning tools involved in environmental management (landscape plan, energy plans, basin plans) are investigated, enlightening…
Il laboratorio di A.
2021
E allora c’è l’uso della tipografia per la composizione del testo, in forma concisa di pensieri sparsi o più strutturata di riflessioni ampie, necessarie per tenere insieme la mente e la mano, per verificare la direzione presa e correggere la rotta se necessario. C’è l’uso del progetto grafico, che di strumenti ne richiede diversi, la tipografia in primis, ma anche le forme, i colori, e poi le gerarchie, le relazioni, e su tutti la traduzione dei contenuti, un continuo processo di mediazione. C’è infine l’uso del disegno, che ha bisogno davvero di pochi strumenti per esistere, un foglio e un pennino, ovvero un piano su cui depositare una bava di inchiostro e uno in grado di spargerlo sulla …
