Le declinazioni della responsabilità penale in materia di pubblica sicurezza: aspetti problematici e soluzioni giurisprudenziali
No full textL’esigenza di una chiara delimitazione delle responsabilità penali di chi è preposto all’amministrazione della pubblica sicurezza si impone (a partire dalla previsione di cui all’art. 28 Cost.) affinché non sia esposto a forme di responsabilità non calcolate e non facilmente prevedibili. Tale rischio si manifesta non solo qualora sia difficile identificare i confini tra le fattispecie penali ma anche, e soprattutto, quando le facoltà e i doveri connessi allo svolgimento delle funzioni di polizia determinino un ampliamento dell’area penalmente rilevante oppure assumano, essi stessi, i tratti tipici di un fatto di reato. Sono queste le linee di approfondimento lungo le quali si sviluppa la ricerca, avendo un occhio di riguardo per gli aspetti più controversi che trovano precisazione grazie allo sforzo dottrinale di ancoraggio ai principi costituzionali e alle alterne soluzioni nell’applicazione da parte degli organi giudicant
The Sustainability of Wildlife in Agroforestry Land
No full textAbstractWildlife management in agroforestry territory has become particularly complex in recent years because of the increase of animal density. This study proposes a review of the literature on the impact of wildlife in many areas of the world. In particular, it examines the negative effects due to the strong growth of wildlife populations and consequently the loss of the balance of agricultural and forest ecosystems. A second portion of the study shows the results of an investigation related to the rural area of the Region of Tuscany: Recreation-Opportunity-Spectrum - ROS (North American Methodology) implemented in Geographical Information System - GIS, is used with the aim of determining suitable areas for damages by wild animals. The final goal of the paper is to highlight some possible choices to be adopted by Stakeholders in order to bring the phenomenon within the limits of sustainability
Le ville eclettiche di Leuca nel basso Salento: problematiche e prospettive di restauro
No full textIl presente contributo ha come oggetto di interesse l’architettura eclettica del basso Salento tra Otto e Novecento e, in particolare, le ville realizzate nella località balneare di Santa Maria di Leuca. L’obiettivo dello studio condotto è di richiamare l’attenzione verso un patrimonio dal riconosciuto valore storico-artistico, ma che appare ancora trascurato nelle sue peculiarità formali e materiali in un’ottica di restauro. Svariati sono, infatti, i casi in cui queste ville versano in un precario stato di conservazione e necessitano di progetti di restauro attenti a conservare il valore storico e documentario di queste architetture
Asymmetric competition between the autochthonous deer ked Lipoptena cervi and the alien L. fortisetosa (Diptera: Hippoboscidae) in Cervus elaphus
No full textDistribution of Deer Keds (Diptera: Hippoboscidae) in Free-Living Cervids of the Tuscan-Emilian Apennines, Central Italy, and Establishment of the Allochthonous Ectoparasite Lipoptena fortisetosa
No full textLipoptena fortisetosa and L. cervi are hematophagous ectoparasites belonging to the Hippoboscidae
family and preferentially living on cervids. In recent years, they have received specific
attention due to the great increase in the abundance of their host species, and to their medical and
veterinary importance as possible vectors of pathogens harmful to humans and animals. The aim of
this study was to investigate the parasitism level of both of these flies on their main hosts in Italy,
which are red deer, fallow deer, and roe deer, and to highlight a possible preference for a species,
sex, or age class among the hosts. Deer keds were collected by examining 326 cervids hunted in the
Tuscan-Emilian Apennines. Outcomes showed that L. fortisetosa has greatly spread throughout the
study area, where it competes with the autochthonous L. cervi. Moreover, red deer was the favored
host species of both ectoparasites, while different preferences for host sex and age classes were
observed in the two hippoboscids. The regular monitoring of deer ked populations, especially the
allochthonous L. fortisetosa, which is continuously spreading in Europe, is recommended to expand
the knowledge on these parasitic species that are potentially dangerous to public health
Acoustic analysis of some characteristics of red deer roaring
No full textDifferent strategies have been adopted to track and monitor red deer (Cervus elaphus) populations according to different habitats and ecosystems. The population census techniques usually carried out are time consuming and involve lot of manpower. A method that relies on individual animal signs like acoustic indices could be useful to support the wildlife management, since vocalisations can encode and transmit a variety of biologically significant information. The present study considered 460 roars recorded from 14 adult deers, from five to eight years old. Recordings were performed in five different locations of northern-central Italy. The acoustic spectrum of each roar was analysed in order to extract its main features, namely: the fundamental frequency (F0), the peak frequency (PF), the sound length (SL) and 24 frequency bins of 174.3 Hz, representing the sound distribution between 50 and 4233.2 Hz (F1 to F24). Statistical analyses showed that individuality and age of animals were significant on F0 (P0.90; P<0.001), indicating that age could influence the spectral features of roaring. The roaring frequency variables appear to be indicators of the individuality of male deer, even if the strong influence of age on the emitted sounds could compromise the reliability of the method over long periods of time

No full textUn metodo per l'elaborazione del piano di manutenzione dopo il restauro
No full textQuesto contributo ha come finalità la presentazione di un metodo per l’elaborazione del piano di manutenzione del Palazzo della Cancelleria a Roma, atto a preservare la materia restaurata, che si caratterizzi per praticità ed efficienza. Il sistema che si propone prevede l’utilizzo della tecnologia Building Information Modeling, attraverso la quale sarà possibile ottimizzare tempo e risorse economiche, organizzando le attività in grado di controllare, correggere e rallentare il normale degrado dei materiali costituenti l’opera architettonica
Multiple Myeloma Impairs Bone Marrow Localization of Effector Natural Killer Cells by Altering the Chemokine Microenvironment.
No full textNatural killer (NK) cells are key innate immune effectors against multiple myeloma, their activity declining in multiple myeloma patients with disease progression. To identify the mechanisms underlying NK cell functional impairment, we characterized the distribution of functionally distinct NK cell subsets in the bone marrow of multiple myeloma-bearing mice. Herein we report that the number of KLRG1(-) NK cells endowed with potent effector function rapidly and selectively decreases in bone marrow during multiple myeloma growth, this correlating with decreased bone marrow NK cell degranulation in vivo. Altered NK cell subset distribution was dependent on skewed chemokine/chemokine receptor axes in the multiple myeloma microenvironment, with rapid downmodulation of the chemokine receptor CXCR3 on NK cells, increased CXCL9 and CXCL10, and decreased CXCL12 expression in bone marrow. Similar alterations in chemokine receptor/chemokine axes were observed in patients with multiple myeloma. Adoptive transfer experiments demonstrated that KLRG1(-) NK cell migration to the bone marrow was more efficient in healthy than multiple myeloma-bearing mice. Furthermore, bone marrow localization of transferred CXCR3-deficient NK cells with respect to wild type was enhanced in healthy and multiple myeloma-bearing mice, suggesting that CXCR3 restrains bone marrow NK cell trafficking. Our results indicate that multiple myeloma-promoted CXCR3 ligand upregulation together with CXCL12 downmodulation act as exit signals driving effector NK cells outside the bone marrow, thus weakening the antitumor immune response at the primary site of tumor growt
