Variations on the Author
No full text“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship

Caratterizzazione chimica, enzimatica e microbiologica del latte e della mozzarella di bufala prodotti in provincia di Foggia
No full textSUMMARY – Chemical, enzymatic and microbiological features of buffalo milk and mozzarella cheese produced in the province of Foggia.
The experiment was conducted in three buffalo dairy farms located in the province of Foggia (Apulia, Italy). Bulk milk was analyzed for chemical, hygienic and enzymatic parameters and the impact of milk features on mozzarella cheese quality was investigated. Three sampling cycles were performed in each farm at weekly intervals; bulk milk collected from each farm was processed for mozzarella cheese production according to an industrial protocol.
Milk somatic cell count was always lower than 3 log10 SCC/mL and bacterial cell load was lower than 5 log10 cfu/mL and 3 log10 cfu/mL for total bacterial count and total coliforms, respectively. These results evidenced a good hygienic quality of buffalo milk due to a good dairy farming practices. Endogenous proteolytic enzymes as plasmin-plasminogen system, cathepsin D and elastase displayed activities lower than those detected in cow, sheep and goat milk due to the lower somatic cell count in buffalo milk. Moreover, these enzymes were affected by the processing technology of mozzarella cheese; in particular, the acidification step could be responsible for the higher activity of cathepsin D whereas the stretching phase may be involved in the conversion of plasminogen to plasmin.
Finally, principal component analysis was performed on a matrix of 16 fatty acids to discriminate acidic profile of buffalo milk and mozzarella cheese. Fatty acid profile reflected the one recorded in the corresponding milk due to the absence of the lipolytic process occurring during cheese ageing
Areal Identification of Groundwater Nitrate Contamination Sources in Periurban Areas.
No full textBackground, Aims and Scope. The purpose of this study is to verify a method for groundwater contamination risk assessment in urban and periurban areas using Geographic Information Systems (GIS). The method is based on agricultural hazard evaluation. In urban and periurban areas, the problem of dealing with NO3 concentrations mainly entails identifying nitrate sources from the excessive use of fertilizers, or leaks from the sewage network and old septic systems. Residential areas coexisting with farming, and high and increasing nitrate concentrations, were identified in a densely inhabited area (>2 million inhabitants in about 1,000 km2) with an alluvial aquifer, located in southern Italy. Methods. First of all, comparison between the Contamination Vulnerability Map and the distribution of NO3 concentrations highlights anomalous areas with low or moderate vulnerability in spite of the diffuse nitrate contamination of the aquifer. Assuming the agricultural origin of the nitrates, the hazard is calculated using the ANHI (Agricultural Nitrate Hazard Index), a parametric index which assesses the potential hazard of nitrate contamination originating from agriculture on a regional scale (Padovani and Trevisan 2002). The ANHI integrates two categories of parameters: the hazard factors (HF), which represent all farming activities that cause, or might cause, an impact on soil quality in terms of nitrate (use of fertilizers, application of livestock and poultry manure, food industry wastewater and urban sludge), and the control factors (CF) which adapt the hazard factors to the characteristics of the site (geographical location, climatic conditions and agronomic practices). Organization, processing and mapping are performed using a Geographical Information System (GIS: ILWIS 3.3 and ARCGIS 9.1). Results. The ANHI Map is obtained by multiplying the hazard factors (HF) and the control factors (CF), and dividing the resulting values into 6 classes. Finally, the Potential risk Map (R) is obtained by coupling the potential hazard of nitrate pollution (ANHI) and the aquifer Contamination Vulnerability Map. Discussion. By using spatial statistics, the Potential Agricultural Nitrate Contamination Risk Map and the Nitrate content of the aquifer correlation can be correlated. Where areas with low corland' class, the source of the groundwater nitrate is not necessarily related to intensive farming and livestock. Conclusions. The Potential Agricultural Nitrate Contamination Risk Map in urban and periurban environments indicates the relationship between the high nitrate values and land use, giving useful information about the source of nitrate in groundwater. Recommendations and Perspectives. Based on this study, we formulate a hypothesis on the source of groundwater nitrate which should be verified on several case studies using nitrogen isotope techniques
Il rischio di Inquinamento da nitrati di origine agricola nella Piana del F. Volturno: il test site di Acerra.
No full textL’area di studio, comprende Acerra ed i comuni limitrofi di Casalnuovo e Pomigliano d’Arco. Tutti e tre questi comuni vengono indicati come vulnerabili da nitrati nella Delibera di Giunta Regionale n. 700 del 18 febbraio 2003 (Individuazione delle zone vulnerabili da nitrati di origine agricola ai sensi dell’art. 19 e dell’Allegato VII del D.Lgs. 152/99 e s.m.i.). Inoltre nell’ambito del Piano Regionale di Bonifica delle Aree Inquinate, redatto dalla Regione Campania nel 2005, il territorio del Comune di Acerra ricade tra le 12 aree che sono state individuate. Per l’areale sopra delineato è stata applicata una metodologia, di recente portata all’attenzione della comunità scientifica (Padovani & Trevisan, 2002), finalizzata alla valutazione del rischio di inquinamento da nitrati di origine agricola. Tale metodica prevede la realizzazione di più carte tematiche (es.: C. della vulnerabilità all’inquinamento degli acquiferi, C. dell’indice IPNOA etc.) che vengono fatte tra loro interagire in ambiente GIS secondo uno specifico algoritmo fino all’ottenimento della Carta finale del rischio. La carta del rischio potenziale di contaminazione da nitrati di origine agricola elaborata sulla base del metodo IPNOA mostra una buona correlazione spaziale con il contenuto in nitrati della falda principale. Ciò suggerisce che in questo settore l’origine dei nitrati è prevalentemente di origine agricola. In futuro, il lavoro svolto in ambiente GIS può consentire, anche attraverso studi di statistica spaziale fra aree contaminate e aree potenzialmente a rischio, di identificare quegli “indicatori” di contaminazione da nitrati di origine agricola della falda realmente significativi e quindi di implementare le metodologie di valutazione del rischio di inquinamento da nitrati
Imparare le lingue per abbracciare il mondo
No full textL’autrice che si colloca, come Daniela Zorzi, tra i fautori di una linguistica “impegnata”, propone in ricordo della studiosa amica, una riflessione sul ruolo cruciale del multilinguismo e delle lingue- culture, per il successo professionale e il benessere sociale, nella società contemporanea. Il multilinguismo appare come un’urgenza educativa che interpella studiosi e formatori a tutti i livelli al fine di promuovere nei giovani un apprendimento consapevole efficace ed autonomo.Multilingualism constitutes an urgent objective for education, which needs to involve teachers and researchers at all levels if we are to promote effective and autonomous learning in the young. Like Daniela Zorzi, the author considers herself a socially engaged linguist, and in memory of her friend’s work, offers a reflection on the key roles of languages and cultures and of multilingualism for professional success and social welfare today
The Effect of the Psychological Sense of Community on the Psychological Well-Being in Older Volunteers
No full textAgeing populations across Europe are increasing. Communities have an important role in not only engaging this segment of the population
but also in helping them to make them feel “part of something” (local or global) in order to favour their psychological well-being. The purpose
of this paper is to study the effects of volunteering and being connected in one’s community on well-being. The present paper will test an older
volunteers’ psychological well-being model. 143 older volunteers completed measures of religiousness, sense of global responsibility,
psychological sense of community, generativity, motivation to volunteer and a profile of mood states. Data show that a psychological sense
of community has a key role in the study of older volunteerism due to its impact on well-being. Service agencies and administrations can
develop campaigns to sustain older volunteerism in order to increase well-being and reduce social costs
Reclamações ambientais em Aveiro, Portugal: atores, preocupações, padrão territorial e resoluções
No full textThis paper presents an environmental diagnosis based on public complaints on environmental
issues submitted to the Environmental Department of the Aveiro City Council, Portugal, between
2000 and 2005. It discusses the potential influences of these in local environmental planning
and governance. The paper has been organised into five sections. The first of these introduces
the study. The second section focuses on the conceptual approaches relating to environmental
grassroots movements, the main actors involved in these movements and the role played by
local government. It also contains a brief review of the most recent urban environmental
quality challenges in the European context together with a description of the main features of
the associated political and legal framework in Portugal. The third section describes the case
study and the methodology used. The results of the empirical study are detailed in the fourth
section. The final section critically analyses these results with emphases on the temporal
evolution of the submission of complaints, the actors involved, the local environmental problems
and their associated spatial pattern as well as the responses given by the City Council. This
information may then be used to provide a useful indicator for the perception of environmental
quality as well as a credible instrument for the visualisation and evaluation of local performance
in terms of environmental planning and management.AlBan Programme - n. E05M053040B
Di cosa parliamo quando parliamo di Nord-Est
No full textA partire dagli anni Sessanta, e con un’accelerazione negli ultimi decenni del XX secolo, la continua crescita dell’urbanizzazione ha portato nelle fasce meridionali delle sezioni di valle alla saldatura di cornici urbane al di là dei confini regionali, nonché all’accorpamento di centri urbani, insediamenti dispersi e una varietà di usi del suolo, paesaggi e ambienti rurali con caratteristiche comuni. Quest’ultimo processo ha caratterizzato soprattutto le celle collocate sulla pianura umida veneta, che ora appare come un esteso sistema metropolitano policentrico
