First assessment of natural regeneration and seed dispersal of Persian walnut (Juglans regia L.) in Mediterranean agroecosystems
2020
Persian walnut (Juglans regia L.), which is native to Central Asia, has been widely cultivated throughout Europe over millennia as a multipurpose tree. However, only recently the naturalization process outside cultivation has been studied, mostly in temperate Europe, with no information regarding the Mediterranean region. Here we provide the first field investigations about the natural regeneration of walnut in two traditional Mediterranean agroecosystems: an irrigated mixed orchard in suburban areas and a non-irrigated prickly pear (Opuntia ficusindica [L.] Mill.) orchard. The natural regeneration densities were statistically different in the two agroecosystems, ranging from 75 individuals…
The recruitment of scallops (and beyond) by two different artificial collectors (Gulf of Taranto, Mediterranean Sea)
2015
This study provides for the first time an evaluation of the natural availability of scallop seeds along the coastal area of Taranto (Mediterranean Sea, Southern Italy). To select the best artificial collectors to harvest scallop seeds in this area, cylindrical collectors (Cyl) were compared to traditional 'Japanese-style onion bags' (Bag) across three sites. Scallops represented 26.6% of total bivalve recruitment among all collectors (782 ± 331 ind. m-2). The most recruited scallops were Flexopecten glaber and Mimachlamys varia. The white (F. glaber) and black scallops (M. varia) were abundant at all three sites, while the queen scallop, Aequipecten opercularis, was only found at one site. …
Increasing tree survival to facilitate the conversion of conventional systems to agroforestry systems using plant growing aids and plant-plant facili…
2022
Several global commitments have established a compromise to greatly increase the presence of trees in agricultural lands, fostering therefore the adoption of agroforestry systems and the destination of some areas for reforestation. Such tasks are challenging, particularly under the current climate change scenarios, and several studies have demonstrated a high risk of seedling mortality under harsh and extremely variable environmental conditions, calling for solutions that must increase the success and reduce the costs of growing a tree. In this study, inside the project LIFE Desert Adapt, we tested the effects of different types of growing aids such as shelters, mulching and innovative meth…
SOCIETÀ A CONTROLLO PUBBLICO E CONTRATTO DI LAVORO: LA CASSAZIONE TORNA SULLA NULLITÀ VIRTUALE PER ALTERAZIONE DELLA PROCEDURA CONCORSUALE
2021
Il commento analizza la recente e consolidata giurisprudenza di legittimità in materia di rapporto di lavoro alle dipendenze delle società a controllo pubblico: secondo la Corte di Cassazione, che fa leva sui principi generali in tema di nullità contrattuale e di buon andamento e imparzialità dell’agere amministrativo, la nullità della procedura di reclutamento per violazione di norme imperative costituisce causa di nullità virtuale dei contratti di lavoro sottoscritti in esito ad essa, a prescindere dalla circostanza che i lavoratori abbiano dato causa al vizio o ne abbiano avuto consapevolezza. Tale orientamento è stato del resto formalizzato in progresso di tempo dal legislatore con il d…
Labor Market Imbalances and Personnel Recruitment
2019
When the economy of a country starts to expand or collapse in wealth, it is reflected in the labor market with an impact on employment and personnel recruitment processes. The aim of this article is to investigate the relationship between personnel recruitment and job market imbalances in the various de- velopmental conditions of the macroeconomic environment. Research find- ings show that employers tend to adopt more active, formal, competitive, targeted, and selective search behaviors in the positive cycles of the economy and employment. Conversely, in downturns of the economy and employ- ment, employers tend to be more passive and defensive, relying on informal relationships and, in some…
Jobseeking Behaviour Theory: implicazioni per I datori di lavoro e i loro processi di reclutamento
2016
La Jobseeking Behaviour Theory (JBT) è un insieme di contributi multidisciplinari che nasce per comprendere come le persone cercano lavoro e come le istituzioni possono aiutarle a trovarlo. Questo articolo si prefigge di ricostruire un quadro sistematico della JBT allo scopo di individuarne le implicazioni per i datori di lavoro e i loro processi di reclutamento. Inizialmente verranno esaminate le dimensioni di analisi e valutazione dei comportamenti di ricerca. Successivamente verranno illustrati i riferimenti teorici e le evidenze empiriche relativi alle relazioni che intercorrono fra variabili economiche, psicologiche, sociali, demografiche, occupazionali, tecnologiche e comportamenti di…
Persone, organizzazioni e intermediari alla ricerca del lavoro
2021
Il primo capitolo illustra i cambiamenti che stanno interessando le economie e le societ contemporanee sia con riferimento al contesto nazionale che internazionale e il loro impatto sui processi di ricerca. A questo scopo il capitolo prende in esame una serie di fattori demografici, aziendali, economici, politici e tecnologici i cui trend stanno rendendo sempre pi critico il tema della ricerca delle risorse umane. Il secondo capitolo prende in considerazione la ricerca dal punto di vista delle organizzazioni aziendali. Esso si articola in tre parti. Nella prima parte si spiega la collocazione teorica della funzione organizzativa nel quadro della teoria generale delle risorse umane. Succes…
Contrasting age-specific recruitment and survival at different spatial scales: A case study with the European storm petrel
2009
Evolutionary studies on optimal decisions or conservation guidelines are often derived by generalising patterns from a single population, while inter-population variability in life-history traits is seldom considered. We investigated here how survival and recruitment probabilities changed with age at different geographical scales using the encounter histories of 5523 European storm petrels from three Mediterranean colonies, and also how our estimates of these parameters might be expected to affect population growth rates using population matrix models. We recorded similar patterns among colonies, but also important biological differences. Local survival, recruitment and breeding success inc…
Spatio-temporal statistical methods in environmental and biometrical problems
2017
This is the editorial letter for the Special Issue dedicated to the VIII International Workshop on Spatio-temporal Modelling (METMAVIII) which took place in Valencia (Spain) from 1 to 3 June 2016, and to the second Galician-Portuguese meeting of Biometry, with applications to Health Sciences, Ecology and Environmental Sciences (BIOAPP2016) held in Santiago de Compostela (Spain), 30–2 July 2016. This special issue summarises and discusses selected peer-reviewed contributions related to spatial and spatio-temporal statistical methodologies comprising both new methodological approaches and a wide range of applications related to environmental and biometrical problems. Point processes, lattice …
Influence of respiratory rate and end-expiratory pressure variation on cyclic alveolar recruitment in an experimental lung injury model
2012
Introduction Cyclic alveolar recruitment/derecruitment (R/D) is an important mechanism of ventilator-associated lung injury. In experimental models this process can be measured with high temporal resolution by detection of respiratory-dependent oscillations of the paO2 (ΔpaO2). A previous study showed that end-expiratory collapse can be prevented by an increased respiratory rate in saline-lavaged rabbits. The current study compares the effects of increased positive end-expiratory pressure (PEEP) versus an individually titrated respiratory rate (RRind) on intra-tidal amplitude of Δ paO2 and on average paO2 in saline-lavaged pigs. Methods Acute lung injury was induced by bronchoalveolar lavag…
