No full textMorphometric characterization of Mesola red deer Cervus elaphus italicus (Mammalia: Cervidae)
No full textThe red deer of the Bosco Mesola Nature Reserve (northern Italy) constitute a population with relevance for zoogeography, genetics and conservation. We have analysed morphometrics of Mesola red deer (body weight, craniometry, stature, antler conformation and size) over a c. 30 year period (1980-2012), to (i) describe in detail their physical traits, (ii) compare them with those of other European populations and (iii) assess the effects of conservation actions on biometric measures of individuals. Mesola red deer were on average 15-50% lighter and at least 8-15% smaller than other European red deer. The sexual size dimorphism was low and significant only for adults. Body growth rate was also slower than that of the other European populations. While the average relative production of antler bone tissue appeared not to be different from that of other European red deer, antlers of Mesola stags were small and scarcely branched, with short trez tines. Bez tine and crown were rare and present almost exclusively in fully mature stags (2.2 and 3.6% of antler beams in adult stags, respectively). Environmental improvements led to significant favourable effects on antler size and complexity. All observed individuals had a distinct but slight spotting of the summer coat. These morphological characteristics, coupled with genetic peculiarities, make the Mesola red deer unique, deserving special protection. © 2014 Unione Zoologica Italiana
Geomorfologia e poleogenesi nella VIII Regio augustea. Considerazioni sui siti urbani d’età antica. Geomorphology and poleogenesis in the Augustus’ 8th Region. Considerations on ancient urban sites.
No full textLa realizzazione della bonifica di un ambito territoriale richiede un potere economico commisurato all’ampiezza dell’area da considerare e, ovviamente un patrimonio conoscitivo/tecnologico adeguato alle caratteristiche dell’obiettivo. Ma soprattutto un modello organizzativo-sociale, politico, militare anche, di sufficiente respiro. Prima dello studio dell’intervento di bonifica sul territorio viene quindi l’analisi distributiva del popolamento e della definizione gerarchica dell’insediamento su di esso cioè , in buona sostanza, dell’ubicazione dei centri urbani. In questo la geomorfologia riveste sicuramente un ruolo fondamentale e primario. Vengono confrontate le condizioni fisiografiche delle ubicazioni delle città storiche dell’Emilia-Romagna in rapporto alla cronologia nota dell’insediamento e si evidenzia l’anomalia del caso della città di Modena che ha fruttato a questa la possibilità di associare il proprio toponimo alla stratigrafia regionale. Essa si presenta infatti 8 km a valle della posizione che avrebbe potuto/dovuto possedere in consonanza con quella delle altre città coeve. Ciò ha comportato problemi gravi all’impianto urbano che resilientemente ha levitato di quota ma contemporaneamente ha subito una parziale traslazione laterale, fenomeno unico nella casistica regionale. La logica ubicatoria va quindi imputata ad un fattore di ereditarietà da preesistenza oppure ad una logica cogente di altro tipo che potrebbe ravvisarsi nella presenza di un paleoalveo collettore dei fiumi Secchia e Panaro a valle della città antica

Ostacoli al cammino della Prevenzione Basata su Prove di Efficacia - Obstacles which have hampered the progress of Evidence Based Prevention (EBP)
No full textMolti anni sono trascorsi da quando nell nel 1992 Gordon Guyatt e un qualificato gruppo di suoi colleghi dell'Università McMaster di Hamilton in Ontario coniarono il nuovo termine di Evidence Based Medicine. Il campo della prevenzione primaria, tuttavia, è stato posto al centro del dibattito sulle prove di efficacia degli interventi solo dopo la metà degli anni novanta, grazie soprattutto all'iniziativa nota col nome di "The Community Guide", nell'ambito dei CDC di Atlanta negli Stati Uniti. A rendere difficile il cammino della Prevenzione Basata su Prove di Efficacia (Evidence Based Prevention - EBP) sono stati diversi ostacoli che qui brevemente cerchiamo di descrivere
Systematic reviews in occupational health and safety: Where are we and where should we go?
No full textSystematic Reviews have been introduced to improve the synthesis of available evidence and to reduce bias in the conclusions about a body of evidence. Nowadays, Systematic Review is an established method also in the Occupational Safety and Health (OSH) field. It is the Cochrane Work Review Group that facilitates authors to produce Cochrane reviews of intervention topics in this area. A variety of guidelines used Cochrane Work reviews for underpinning their recommendations. Due to the comprehensive search and reproducibility of the methods of a systematic review, it turned out that systematic reviews can be powerful in changing beliefs. For example, studies published in the eighties advocated the use of back schools. Nowadays, we know that the total body of evidence has changed the traditional view that training in lifting techniques could prevent back pain. ‘Sitting is the new smoking’ is an eye catching nicely alliterating motto, but it is of course highly overstated. The findings of a Cochrane review of the effects of interventions to decrease sitting at work showed that sitting time can be reduced by a bit less than two hours per day by providing sit-stand desks plus education. However, it is unclear if this is sufficient to counter the effects of sitting. A wealth of evidence on OSH interventions has been collected by international collaboration in the Cochrane Work Review Group. This can be extended to systematic reviews of the effects of exposure of workers to assess to which risks of adverse health effects they are exposed
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
Patologie del rachide in autotrasportatori artigiani
No full textThe truck driver's work requires sitting in a fixed posture for prolonged periods when driving. Such conditions involve exposure to whole body vibrations. In addition, during loading and unloading operations, often done by hand, there is a further excess load on the spine. The paper presents the results of an investigation on the frequency of spinal disorders among self-employed truck drivers. A total of 606 truck drivers belonging to a trade union were interviewed and 63 subjects using the methods proposed by the "Ergonomics of Posture and Movement Research Unit" of the "Clinica del Lavoro" of Milan were examined. There was an elevated frequency of herniated disk and the risk was 4 times higher compared to the control population. The frequency of functional spondyloarthropathy of the cervical and lumbar segments was particularly high, especially in the older age classes (71.4% and 35.7%). The authors conclude that disease of the lumbar spine leads in a very large number of cases to permanent working incapacity among truck drivers before pensionable age.The truck driver's work requires sitting in a fixed posture for prolonged periods when driving.
