Abitare la città nella cultura odierna. Il ponte tra rigenerazione dello spazio e progetto
No full textIn una società in cui la comunicazione, più che un’esigenza, è un modo di vivere l’innovazione in linea con il percorso evolutivo della storia e del progresso scientifico, in un’epoca in cui la sostenibilità, più che un’esigenza, è un modo di guardare al futuro che reinterpreta il vivere in armonia con la natura, il progetto dello spazio esterno deve relazionarsi al sistema infrastrutturale, nella consapevolezza del nuovo ruolo che riveste. In questo scenario, il ponte si configura come una delle nuove architetture capace di rigenerare la città, in quanto spazio da abitare, avvalendosi sia di nuove connotazioni materiche, sia di nuove valenza simboliche, che si relazionano alla percezione. Inoltre, nella sua interazione materica con il verde e l’acqua, il ponte riesce a riformulare il tema della città in termini di mobilità intelligente, sostenibile, più naturale e a volte anche più efficiente energeticamente
Use of bio activators to replace agro chemicals
No full textBiostimulants are defined as "containing substances and/or micro-organisms to stimulate natural processes in order to improve nutrient absorption and efficiency, tolerance to abiotic stress, and crop quality" according to the European Biostimulants Industry Council (EBIC, 2012), which creates a legal framework for marketing and the regulation of these products.
In the last two decades, the possible use of biostimulants to improve crop production though sustainable agriculture have attracted the interest, not only of the farmers, but also of the scientists as it could represent a tool to combat damaged farmland and the uncertainties of climate change. The objective of the research project I pursued during my PhD training was to select the plant growth-promoting bacteria, a specific category of biostimulants, among a collection of environmental isolate
MATERIALI NATURALI E DI RICICLO NEL PROGETTO DELL'INVOLUCRO EDILIZIO
No full textThe goal of energy efficiency is pursued with high performance materials at the cost of economically onerous production cycles which often impact the environment. In contrast, the use of natural materials and recycling is a much more sustainable choice starting from little energy-production cycle, construction site, implementation, useful life finishing with the building disposal. According to one of the central themes of the energy conscious design, the object of this present study consists in different models of building envelope, designed only by using natural materials and of recycling. The interaction occurs between brick wood-cement-hemp, mud bricks, cellulose fibers, mycelium of mushrooms, plasters lime mortar or clay. Some of these materials are raw products, so they have maximum sustainability, in addition to being completely recyclable. Some materials are natural and therefore are subject to chemical reactions which customarily occur in the environment while others are produced with recycled materials and /or zero km materials, and then they use a particular resource that is the raw material second. The study concludes with a series of comparisons that highlight varied performance levels, but still very performing
Knowledge and attitudes about cancer pain management: a national survey of Italian hospice nurses
No full textTo obtain information about the knowledge and attitudes of Italian hospice nurses concerning cancer pain management and to determine the predictor of nurses' pain management knowledge. Nationwide descriptive study. Hospice nurses in Italy from 9 hospice units distributed in the north, center, and south of Italy. Sixty-six nurses completed the questionnaire, indicating a 66.6% response rate. The Nurses' Knowledge and Attitudes Survey (Italian version) and a background information form were used to collect the data. Knowledge and attitudes regarding cancer pain. Among the 39 pain knowledge questions assessed, the mean number of correctly answered question was 24.4 (SD = 4.2), with a range of 15 to 35 items correctly answered. The correct answer rate for the entire scale, on average, was 62.7% (SD = 28%). Further analysis of items showed that more than 30% of hospice nurses underestimated the patients' pain and they did not treat the pain in the correct way; they had an incorrect self-evaluation about their pain management knowledge. Results from stepwise regression showed that nurses with higher mean correct answer scores had attended more courses on pain education. From these results, we conclude that there are still significant knowledge deficits and erroneous beliefs that may hamper treatment of hospice patients in pain. The results of this study could be useful to institutions involved in the education and application of patient pain management
[The world of nursing burnout. A literature review]
No full textThe aim of this paper is to photograph, through a literature review, the burnout and all its related aspects in the world of nursing. We have selected 40 papers with a specific valence which frame and study the nursing burnout in an appropriate way. This topic has been studied in all of the continents, apart from South America. The burnout has been subject of analysis in all the departments, whom oncology and psychiatry result the ones with the highest frequency of studies. In this paper all the studies have been divided into three categories according to their objective: studies on aspects related to the burnout (57,5%), comparative studies (25%), studies on the burnout level (17,5%). From the studies concerning the related aspects comes out that the burnout is strongly related to the coping strategies, the stress index and the personal accomplishment and these factors are highly predictive. Beside that, the data show some disagreements concerning the relation between burnout and sex and burnout and age. The comparative studies show that nurses are, between health care staff, the ones which run the highest risk of burnout, especially the oncologic nurses and nurses working with AIDS patients. This literature review, summing up which steps the research has done and which are still to do, reflects the strong importance of the problem called burnout and the aspects related to it inside the world of nursing. This review underlines the importance of an insertion of support group inside the clinical practice to avoid the risk to have sick persons who take care of other patients

Knowledge and attitudes about cancer pain management: a national survey of Italian oncology nurses
No full textThe purpose of this study was to obtain information about the knowledge and attitudes of Italian oncology nurses concerning cancer pain management and to determine the predictors of nurses' pain management knowledge. The study was a nationwide descriptive survey and included 287 nurses in Italy from 21 oncology wards in the north, center and south of Italy. The Nurses' Knowledge and Attitudes Survey (Italian version) and a background information form were used to collect the data. Knowledge and attitudes regarding cancer pain were the main research variables. Among the 39 pain knowledge questions assessed, the mean number of correctly answered question was 21.4 (SD=5.5), with a range of 6-35. The correct answer rate for the entire scale, on average, was 55% (SD=25.9). Further analysis of items showed that more than 50% of oncology nurses underestimated the patients' pain and they did not treat it in the correct way; they also had an incorrect self-evaluation about their pain management knowledge. Results from stepwise regression showed that nurses with higher mean correct answer scores had attended more courses about pain education. There are still significant knowledge deficits and erroneous beliefs that may hamper treatment of oncology patients in pain. The results of this study could be useful to institutions involved in patient care and teaching of pain management
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
