I processi partecipativi nell'esperienza del Piano Paesaggistico Regionale del Friuli Venezia Giulia
Full text linkThe paper aims at reflecting on the authors' experience in the drafting of the Landscape Plan of Friuli Venezia Giulia Region. The preliminary programming documents of the Region attributed a relevant role to the processes of citizens’ engagement in the reconnaissance step and for the development of the instruments of the Plan. The University of Udine, tasked with supporting the elaboration of the Plan, has organized and carried out the participatory processes aimed at bringing out the feeling of the local populations in terms of values, critical issues, visions and actions finalized to prefigure the "desired" landscapes of the future. It intends therefore to expose the methods and criteria followed to implement full-scale participation and evaluate its positive aspects (the pathways have been undoubtedly successful) and some criticalities related to previous and therefore unavoidable choices. The final aim of the contribution is to draw from such experience useful indications for other similar experiences

Blood pressure and cognitive impairment in the elderly
No full textThe prevalence and incidence of dementias are expected to increase in the future. Accordingly, the identification of causes of dementia and of possible risk factors is very important. A large body of evidence has shown that hypertension is a risk factor for vascular dementia. Recently, it has been demonstrated that hypertension could affect the course of Alzheimer disease. A strong relationship between hypertension and cognitive decline (CD) or dementia has been reported by several observational studies, especially in untreated subjects. The risk increases with increasing blood pressure (BP). However, this relationship is not linear, since BP may decrease to normal or low levels before dementia becomes clinically manifest. There may also be an association between BP variability in hypertensive patients and impaired cognition. Recent studies, using the 24-hour non-invasive monitoring, have shown that both short-term and long-term BP variability are associated to CD. This variability may reflect central nervous system dysregulation or occult injury to prefrontal autonomic centers. Trials with antihypertensive drugs focusing on CD and dementia have shown that active treatment may be beneficial, although the optimal BP levels have not yet defined. Future studies, comparing the different effect of antihypertensive drugs are expected to further clarify this topic. © 2006 Bentham Science Publishers Ltd
Outcomes of a computer-based cognitive rehabilitation program on Alzheimer's disease patients compared with those on patients affected by mild cognitive impairment
No full textThe aim of the present study is to evaluate the outcomes of a computer-based cognitive training on patients affected by Alzheimer's disease (AD) compared with the outcomes on patients affected by mild cognitive impairment (MCI), multiple system atrophy (MSA). Ten AD patients aged 74.1+/-5.6 years, with mini-mental state examination (MMSE) score at baseline of 23.9+/-2.4, and 10 MCI patients aged 70.6+/-6.0 years, with MMSE score of 28.0+/-1.4, attending our day-hospital of neurorehabilitation were selected for the study. Three MSA patients aged 69.0+/-9.5 years, MMSE scores 26.7+/-2.3 were selected from the same setting in order to have a different control group. Each patient attended two training programs and was evaluated according to cognitive and non-cognitive functions at baseline at the end of the second training program. The AD group showed a significant MMSE score improvement (p=0.010). On the contrary, MMSE scores at baseline and at follow-up remained quite stable in the other two groups. AD patients also showed significant improvement in the areas of verbal production (p=0.036) and executive functions (p=0.050). MCI patients significantly improved in behavioral memory (p=0.017; p=0.011). No significant improvement was observed in MSA group. Our data seem to indicate that the same individualized rehabilitative intervention could have different effects according to patient's diagnosis. MCI and AD patients had significant improvements in global cognitive status and/or in specific cognitive areas. On the contrary, MSA patients did not benefit at all
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
Geografia sociale e processi migratori
No full textIl presente capitolo possiede due scopi, uno più evidente e in qualche modo di
superficie ed uno più “sotterraneo” e profondo. Il primo scopo consiste nel voler
analizzare il rapporto che intercorre tra la geografia sociale e il tema delle migra-
zioni, con una particolare enfasi sui processi contemporanei di migrazione inter-
nazionale, indotti dalla globalizzazione e dall’evoluzione degli scenari geopolitici
e geoeconomici a livello mondiale. Il secondo scopo si sviluppa, muovendo da
questo tema, per interrogarsi però su questioni di carattere più squisitamente
epistemologico, legate alla natura, all’evoluzione e anche all’adeguatezza della ge-
ografia, con o senza aggettivi, nel cercare di analizzare ed interpretare i fenomeni
della realtà che ci circonda. In particolare, si vuole tentare di offrire una prospet-
tiva un po’ diversa sul consueto “dilemma” dell’opportunità di una suddivisione
della disciplina geografica in più branche versus, all’opposto, l’esigenza di una sua
unitarietà, rovesciando la logica del ragionamento scientifico di tipo tradizionale.
Quest’ultimo, partendo dallo studio di un fenomeno, come, ad esempio, quello
migratorio, costretto dalla necessità di coglierne le molteplici sfaccettature ed
interdipendenze, può, infatti, svilupparsi secondo un modello che comporti, allo
stesso tempo, la ricerca di approcci di carattere interdisciplinare e l’integrazio-
ne di strumenti e metodi, che tradizionalmente vengono considerati propri di
specifiche articolazioni del sapere e della ricerca geografici. L’unitarietà del tema
(geografia delle migrazioni), lungi dal generare un’ulteriore segmentazione disci-
plinare, permette invece di ricomporre le fratture già esistenti all’interno di essa
