Strategies for waste recycling : the mechanical performance of concrete based on limestone and plastic waste
2022
Recycling is among the best management strategies to avoid dispersion of several types of wastes in the environment. Research in recycling strategies is gaining increased importance in view of Circular Economy principles. The exploitation of waste, or byproducts, as alternative aggregate in concrete, results in a reduction in the exploitation of scarce natural resources. On the other hand, a productive use of waste leads to a reduction in the landfilling of waste material through the transformation of waste into a resource. In this frame of reference, the paper discusses how to use concrete as a container of waste focusing on the waste produced in limestone quarries and taking the challenge…
Ephemeral Arts Connection 2011: così le cave di Marsala sono diventate uno spazio scenico unico...
2011
Sintesi dei risultati dell'Ephemeral Arts Connection 2011, 2° workshop internazionale in Sicilia. Le cave dismesse diventano traccia storica di un’attività produttiva peculiare del territorio, memoria dell’intervento dell’uomo sulla natura, scenario naturale da salvaguardare e valorizzare pensando e proponendo usi e fruizioni alternativi. Il workshop ha lavorato a partire dalla riflessione sulle modificazioni del paesaggio e delle sue risorse, sull’intervento dell’uomo quale produttore di eventi spaziali di alta concentrazione che danno luogo a trasformazioni urbane e territoriali di grande rilevanza paesistica. La coscienza del valore ambientale acquisito come bene comune, la proiezione a …
The emergence of a shared action ontology: building blocks for a theory.
2003
To have an ontology is to interpret a world. In this paper we argue that the brain, viewed as a representational system aimed at interpreting our world, possesses an ontology too. It creates primitives and makes existence assumptions. It decomposes target space in a way that exhibits a certain invariance, which in turn is functionally significant. We will investigate which are the functional regularities guiding this decomposition process, by answering to the following questions: What are the explicit and implicit assumptions about the structure of reality, which at the same time shape the causal profile of the brain's motor output and its representational deep structure, in particular of t…
Does letter position coding depend on consonant/vowel status? Evidence with the masked priming technique
2008
Recently, a number of input coding schemes (e.g., SOLAR model, SERIOL model, open-bigram model, overlap model) have been proposed that capture the transposed-letter priming effect (i.e., faster response times for jugde-JUDGE than for jupte-JUDGE). In their current version, these coding schemes do not assume any processing differences between vowels and consonants. However, in a lexical decision task, Perea and Lupker (2004, JML; Lupker, Perea, & Davis, 2008, L&CP) reported that transposed-letter priming effects occurred for consonant transpositions but not for vowel transpositions. This finding poses a challenge for these recently proposed coding schemes. Here, we report four masked priming…
Sul rilievo costituzionale della responsabilità dirigenziale nell’attuale sistema dei rapporti tra politica e amministrazione
2019
L'articolo intende mettere in luce gli elementi caratterizzanti ed innovativi della responsabilità per risultati dei dirigenti pubblici italiani ed il ruolo di garanzia costituzionale che questa nuova forma di responsabilità può assolvere nell'attuale assetto dei rapporti tra politica e amministrazione. This paper argues for the Constitutional Importance of Accountability for Performance of Public Management in the Italian Legal System.
Role of Sky-gardens in Improving Energy Performance of Tall Buildings
2018
Natural ventilation has been used as a passive strategy for many decades but only now its importance in tall buildings for addressing the issues of high energy usage and reducing carbon footprints is emerging. Sky-gardens can play an important role in successful implementation of natural ventilation through amplification of natural wind speeds. This study presents a state-of-the-art review on optimization of tall buildings energy performance through incorporation of sky-gardens. Pros and cons of use of natural ventilation for multi-story buildings are highlighted. Details of involved technical difficulties and barriers in the construction and operation process of sky-gardens are also given.…
Development of organizational trust among employees from a contextual perspective
2006
It is becoming increasingly accepted that trust in the workplace is an important factor which potentially leads to enhanced organizational performance and can be a source of competitive advantage in the long run (e.g. McAllister 1995, Whitener et al. 1998, Leana & van Buren III 1999, Wicks et al. 1999, Gould-Williams 2003). Although it may be unreasonable to expect that any firm can have boundless trust among employees, the starting point of this paper lies in the argument that organizational trust is more desirable from the viewpoint of the firm’s economic prosperity than its lack. Organizational trust is important for successful socialization, cooperation and effective teamworking (cf. Pu…
How personal resources predict work engagement and self-rated performance among construction workers: A social cognitive perspective
2014
Traditionally, research focussing on psychosocial factors in the construction industry has focused mainly on the negative aspects of health and on results such as occupational accidents. This study, however, focuses on the specific relationships among the different positive psychosocial factors shared by construction workers that could be responsible for occupational well-being and outcomes such as performance. The main objective of this study was to test whether personal resources predict self-rated job performance through job resources and work engagement. Following the predictions of Bandura's Social Cognitive Theory and the motivational process of the Job Demands-Resources Model, we exp…
Organizational Learning Capability and Job Satisfaction: an Empirical Assessment in the Ceramic Tile Industry
2009
Organizational learning capability has been considered an essential issue of an organization's effectiveness and potential to innovate and grow. Although its positive effects on organizations and employees are generally assumed, there is no empirical evidence of its positive association with employee attitudes such as job satisfaction. This paper aims to investigate the relationship between organizational learning capability and job satisfaction through the questionnaire responses of 157 employees from eight companies in the Spanish ceramic tile industry. Results suggest that organizational learning capability and job satisfaction are strongly linked.
Moderating influence of organizational justice on the relationship between job insecurity and its outcomes: A multilevel analysis
2010
A great amount of research has illustrated the evident prevalence of job insecurity in working life and its harmful outcomes for employees and organizations. Some authors have identified factors that can reduce this negative influence. However, up until now, most of these factors have only been studied at an individual level, without taking into account the fact that contextual conditions can play a moderating role in organizations. Following this perspective, this article analyses the moderator role of organizational justice and organizational justice climate in the relationship between job insecurity and its outcomes. The study was carried out with a sample of 942 employees from 47 Spanis…
