Sustainability, Store Equity, and Satisfaction: The Moderating Effect of Gender in Retailing
2021
Currently, sustainability emerges as a key element on which the development of competitive advantages for businesses is based. In the dynamic and turbulent environment in which retail companies operate, sustainable practices are posited as an opportunity for their progress and survival. Through this article, it is intended to advance the nature and dimensions of this construct and examine its influence on store equity and consumer satisfaction. Furthermore, this work analyses the moderating effect of gender on these variables and the mediating nature of brand equity in the development of consumer satisfaction. All this is developed through a quantitative study carried out on a sample of 510…
Recent trends of urban development and town planning in Spain
1986
With the socio-economic change from rural to industrial, Spain has experienced an enormous urbanisation boom during the last 20 years. This has produced a concentration of high-rise apartment blocks not only in the big cities but also in medium-sized towns and even within the medieval town centres. More astonishing, compared with Central Europe, seems however, the spatial distribution of the social classes which, with a centre-periphery gradient, still corresponds to the model of the pre-industrial town. The paper investigates the impact of town planning, house building policy, and behavioural aspects on these structural patterns.
Effects of compositional and textural characteristics of clay based plasters on the control of indoor relative humidity
2015
Air humidity in contained spaces has a significant impact on health of inhabitants. The control capability of indoor relative humidity (RH) of clay-based plasters was tested on a series of commercially available products specifically designed for wall undercoating and on a natural earth collected in the surrounding area of Palermo. The innovative practice of ‘‘green building’’, since several years, led the interest of research to recyclable and reusable traditional materials that, in several cases, are a sustainable alternative to concrete and lime mortars. Earthen plasters, in general, have the ability to balance indoor humidity like no other classic building materials. The studied samples…
LONG-TERM STRUCTURAL DEFICIENCIES IN A MAT FOUNDATION ON CLAY SOIL
2013
A 3-story building with a mat foundation consisting of a slab on a grid of grade beams performed poorly on clay soil. Cracking of the slab became rogressively worse as a result of the incorrect esign and fluctuations in the groundwater pressure under the foundation. The cyclic presence and absence of water rusted the steel reinforcement, and the sulfates in the clay soil caused formation of ettringite in the concrete. Plastic hinges formed in the slab and settlements occurred, causing damage to the beams. The situation is still in progress and may lead to the collapse of the structure under normal service conditions. The geotechnical and structural investigations performed to survey and ass…
A tool for evaluating geothermal power exploitability and its application to Ischia, Southern Italy
2015
Abstract The paper proposes a method to evaluate the potential for electric power production at any site of possible geothermal interest. Accounting for geological data of the reservoirs, the method allows the computation of the available electrical power of the investigated site. Electrical energy production from geothermal sources is realized through different techniques, such as single flash and double flash, dry steam, and binary ORC plants. The technique chosen to be the most productive is determined by analyzing a specific range of geofluid properties, mainly temperature and pressure. Moreover, each plant typology has a global efficiency that may be correlated to geofluid enthalpy by …
Physical and mechanical properties of sustainable hydraulic mortar based on marble slurry with waste glass
2021
This paper aims to propose and characterize a sustainable hydraulic mortar entirely obtained by the reuse of waste materials, with marble slurry coming from quarries in the north-western Sicily and glass powder coming from a waste collection plant in Marsala (Province of Trapani). The first was used as raw material to produce the mortar binder by a kilning and slaking process, while the second was used as a pozzolanic additive. The chemical and morphological characterization of the marble slurry was done by XRD, FTIR, STA and SEM analyses. Glass powder was analyzed through particle size distribution measurements, XRD and standard pozzolanic tests. Hydraulic mortars constituted by slaked lim…
Tra medioevo e prima età moderna: eclettismi nel Mediterraneo : Ecclettismo consapevole: alcuni casi di approfondimento.
2019
Coexistence and mixture phenomena of different architectural idioms in the early 1500s Sicily are not rare. The present essay evaluates two late Gothic masters, Antonio Belguardo and Girolamo Vicchiuzzo (his epigone), whose activity in Palermo and Alcamo protracts in various and "eclectic" buildings, which go beyond the first half of the XVIth century.
State, Politics and the Legitimacy of Religious Peacebuilders
2016
In this chapter, Steen-Johnsen shows how the failure of religious leaders to challenge the political strategies of the Ethiopian regime affects their legitimacy as spokespersons for peace. Steen-Johnsen shows how this makes the religious leaders appear as accomplices of the state among groups that they try to address with their message of peace. Steen-Johnsen acknowledges that conflicts which appear religious almost always have political dimensions. She shows how retorting to toothless messages of coexistence and appearing alongside government officials, the Ethiopian religious leaders lose legitimacy as spokespersons for peace. Steen-Johnsen suggests considering how relationships between s…
Urban Services to Ecosystems - Green Infrastructure Benefits from the Landscape to the Urban Scale
2021
The aim of this book is to bring together multidisciplinary research in the field of green infrastructure design, construction and ecology. The main core of the volume is constituted by contributions dealing with green infrastructure, vegetation science, nature-based solutions and sustainable urban development. The green infrastructure and its ecosystem services, indeed, are gaining space in both political agendas and academic research. However, the attention is focused on the services that nature is giving for free to and for human health and survival. What if we start to see things from another perspective? Our actions shall converge for instance to turn man-made environment like cities f…
