SOCIAL ECOLOGY AND TRADITIONAL LANDSCAPE ENHANCEMENT. Some issues from a case study in the Gorizia Karst
No full textGovernance approaches combined with sustainable planning and territory and landscape management tools have progressively increased the link to the environment concept from an ecological-naturalistic point of view, leading to a wider and well-structured vision of the future. This idea moves close to sustainable development principles in a potential integration scenario that takes into consideration economic growth, environmental safeguarding and sharing choices.
It becomes extremely important to act for landscape management and enhancement, especially referred to traditional and marginal areas ones, using social ecology practices able to recover/preserve the fundamental ecosystem services, such as biodiversity, supported by active population involvement methods.
In particular, the Gorizia Karst presents itself as a sensitive area where, during the 20th century, deep wounds have been inflicted. The WWI devastation, the post-1945 border (well-known as "Iron Curtain"), the Cold War and the consequent wide military servitude activated on it, have significantly modified the landscape under the morph-functional profile.
The dry karstic grassland, known as “landa carsica” (Natura2000: Habitat Code 62A0), are phytocenoses made up of an extraordinary multitude of species, whose origins are connected with millennial farming practices linked to transhumance. These features make this landscape an extraordinary area whose ecological values are at least equal to the historical-testimonial ones. Most of the past enhancement efforts failed because they were not based on a clear identification of the relationship between different territory elements.
In this sense, the case study analyzes the effects of “sustainable grazing” reintroduction, started in the last three years on about 700 hectares of dry karstic grassland, as an example of social ecology practice. Territory and landscape planning, local heritage sustainable promotion paths come out to be essential tools to achieve a participate planning of traditional landscapes, able to highlight even the eco-system services value of these special environments in an integrated and long term sustainability dimension

No full textIncentivi "488" all'industria negli anni 1996-2004: effetti settoriali e territoriali
No full textFrom the 10 year enforcement of Law 488, it is possible to deduce on one hand its neutrality in terms of industries, in coherence with a low-technology specialization model; on the other hand its contribution to the growth of local systems with cluster organizations emerging or characterized by enterprises with exogenous capital. In accordance with these results, which offer the policy makers supporting elements in the decision-making process in order to exploit the potential of the law, the recent reform of 488 is aimed at making investments more selective and mainly favouring innovative projects, small enterprises and the identification of deprived areas
Sustainable low-input farming system: the case of Marianis-Volpares farm.
No full textA public farm (630 ha) located in Palazzolo dello Stella (UD) (L at. 45°48”N,Long.13°5’0”E) in the
Friuli Venezia Giulia region of Italy, is managed by ERSA (Agenzia Regionale per lo Sviluppo Rurale) in order
to promote environmentally friendly agriculture. The farm is a complex in which agricultural activities will be in
harmony with the environment and landscape. Hedgerows, ditches, woods, ponds of fresh water, wet meadows
and brackish wetlands will be introduced into the farm. Present high input farming systems (HIFS) is in
transition to low input farming systems (LIFS) using good farming practices (GFP) to qualify the agrienvironment.
Seeds suitable for LIFS will be tested; techniques of soil management such as minimum tillage and
direct drilling will be used. Traditional rotation maize-soybean and maize-lucerne will be integrated with more
environmentally friendly crop rotation systems introducing minor cereals, legumes and multi-species meadows
for ley-arable rotation. Crop rotation will be managed to improve soil fertility and carbon sequestration, to
reduce fertilizing intensity, to protect soil from erosion, to maintain soil organic matter (SOM) and soil structure
and to reduce the use of pesticides. Cover crops will be introduced for manuring and catch crops for reducing
water pollution by nitrates. Crop rotation, soil cover, fertilizing intensity, fertiliser uptake, nitrate leaching, mode
of manuring, landscape elements will be used as main indicators. The present herd of 650 heads of cattle will be
reduced to about 540. Buildings, barns for dairy cows, calving pens, and milking boxes will be restored to
improve animal welfare. Energy will be supplied by anaerobic digestion of organic matter mixed with slurry (codigestion)
by cogeneration and tri-generation processes. Meat, milk and dairy products of high quality will be
certificated by labelling systems

No full textOral Cancer. A cohort analysis of prognostic factors in advanced cases. 2003 april-may-june; vol 2,n.2:55-60
No full textBackground - The AA carried out an immunohistochemical and genetic research on p53 tumor suppressor gene and H-ras oncogene in maxillofacial tumors to evaluate the p53 and H-ras status, response to induction chemotherapy, and global survival, keeping up a study performed from many years.
Methods - 25 consecutive cases of squamous cell carcinomas with metastatic nodes were selected on the basis of homogeneous grading (G2). The patients underwent induction chemotherapy (CDDP/5FU), restaging, surgery, and adjuvant radiotherapy. Monoclonal AB, and Dna extration and PCR amplification were utilized, respectively, for immunohistochemical and genetic analysis of p53 and H-ras.
Differences between proportions of contingency tables were assessed by the Fisher Exact Test; correlation analysis was done using Spearmen Correlation Coefficient. Univariate (product limit) and multivariate (proporzional hazards model) methods were used to estimate prognostic variables and related death risk.
Results - The data show a strong association then between H-RAS overexpression and H-RAS genetic mutations (pFisher =0.000064) that between P53 overexpression and P53 genetic mutations (pFisher =0.000203). A significant inverse correlation was found between P53 overexpression and chemotherapy response (r= -0.892, p= 0.0001).
The cumulative survival of the entire cohort at 28 mounths of follow-up is 28.58% (standard error=10.24%).
Percentage of p53 Monoclonal AB linked > 45% is prognostic variable for death risk with relative risk of 8.89 (95% c.i. 2.48-31.90).
Conclusions - These data show that immunohistochemical study should be inserted in the staging system of tumor mostly in the advanced lesions which need multimodality of
treatment. Oncogenetic pattern supplies important elements for diagnostic and prognostic evaluation, besides the classical factors of screening, and it may work together in better therapeutic planning
