The social significance of the Facebook Like button
2015
In this paper we study social aspects of using the Like button for purposes of impression management, identity construction, and maintenance of social ties online. On the theoretical level our investigation combines Goffman’s notion of face-work with concepts of social network analysis, shedding light on what we dub ‘nano-level’ interaction and sociality on social networking sites. Our data come from a 2013 classroom survey in which 26 Finnish university students were asked about their motives for and ways of using the Like button. Our results show that though the Like button was designed to allow users to express their positive evaluations of the contents of Facebook posts, comments, and p…
Socio moroso
2022
Il contributo ha per oggetto la disciplina dei rimedi previsti dall’art. 2344 c.c. rispetto alla mancata esecuzione da parte dell’azionista dei versamenti dovuti a titolo di conferimento. La trattazione include i problemi relativi all’applicabilità di tale complesso sistema rimediale in caso di trasferimento di azioni non liberate, ai sensi dell’art. 2356 c.c., nonché nelle ipotesi di mancata attuazione dei conferimenti di beni in natura.
The discursive construction of leader identity: Tim Cook in a broadcast interview
2016
Tämän tutkimuksen aiheena on tutkia johtajaidentiteetin rakentumista diskursiivisesta näkökulmasta. Sosiolingvistisen tutkimussuuntauksen piirissä identiteetin rakentuminen nähdään kielellisenä prosessina: identiteetti rakentuu vuorovaikutuksessa diskursiivisten prosessien kautta. Tätä taustaa vasten tavoitteena on selvittää, kuinka Applen toimitusjohtaja Tim Cookin johtajaidentiteetti rakentuu haastattelutilanteessa erilaisten kielellisten keinojen kautta. Tutkimuksen keskiössä ovat erityisesti kielellisen asemoinnin keinot eli erilaisten lyhyt- ja pidempiaikaisten identiteettiasemien osoittaminen niin Cookin itsensä kuin haastattelijan toimesta. Teoreettinen viitekehys koostui Bucholtzin …
Elaborazione e validazione di modelli dell’impatto antropico e dei cambiamenti climatici sulle qualità dei suoli in Sicilia, con particolare attenzio…
Il declino della sostanza organica e l’erosione idrica sono due fattori di rischio di degrado del suolo fra i più diffusi in Sicilia. In che misura è possibile contrastarli modificando le attività antropiche ed in particolare quelle in ambito agricolo? Lo scopo della presente ricerca di dottorato è stato quello di mettere a punto dei modelli che permettessero di spiegare le relazioni esistenti fra le azioni dell’uomo in ambito agricolo con la sostanza organica e con l’erosione idrica nei suoli siciliani, tenendo conto anche del clima. Le due indagini sono state svolte separatamente, in parallelo, in aree agricole della Sicilia occidentale per la sostanza organica, sull’intero territorio sic…
Supporting USLE-MM reliability by analyzing soil loss measurement errors
2017
Sampling the collected suspension in a storage tank is a common procedure to obtain soil loss data. A calibration curve of the tank has to be used to obtain actual concentration values from those measured by sampling. However, literature suggests that using a tank calibration curve was not a common procedure in the past. For the clay soil of the Sparacia (Italy) experimental station, this investigation aimed to establish a link between the relative performances of the USLE-M and USLE-MM models, usable to predict plot soil loss at the event temporal scale, and soil loss measurement errors. Using all available soil loss data, lower soil loss prediction errors were obtained with the USLE-MM (e…
USLE-based models: perspectives and limitations in soil erosion modelling
2020
Water soil erosion is a process of detachment and transport of soil particles due to rainfall and runoff and causes the landform modeling on earthʹs surface. The acceleration of soil erosion process through anthropogenic perturbation has severe impacts on soil which becomes qualitatively poor for crop establishment and growth. Planning soil conservation strategies requires prediction technologies of soil loss over a long‐time period. The Universal Soil Loss Equation (USLE), and its revised versions, are widely tested and applied in different environments throughout the world. At present, the USLE continues to be the most applied model for estimating soil loss and still represents the best c…
Sediment delivery processes and chemical transport in a small forested basin
2005
Recent reaserch has directed attention to the properties of the eroded material because of its influence in deposition phenomena and in carrying capacity of pollutant materials
Testing the Universal Soil Loss Equation-MB equation in plots in Central and South Italy
2019
Planning soil conservation strategies requires predictive techniques at event scale because a large percentage of soil loss over a long-time period is due to relatively few large storms. Considering runoff is expected to improve soil loss predictions and allows relation of the process-oriented approach with the empirical one, furthermore, the effects of detachment and transport on soil erosion processes can be distinguished by a runoff component. In this paper, the empirical model USLE-MB (USLE-M based), including a rainfall-runoff erosivity factor in which the event rainfall erosivity index EI30 of the Universal Soil Loss Equation (USLE) multiplies the runoff coefficient QR raised to an ex…
Applying the RUSLE and ISUM in the Tierra de Barros Vineyards (Extremadura, Spain) to Estimate Soil Mobilisation Rates
2020
Spain is one of the largest wine producers in the world, with Extremadura (south-west Spain) being its second-largest producing region after Castilla La Mancha. Within Extremadura, the most traditional and productive viticulture region is the Tierra de Barros, which boasts an annual production of 3×
Solidaridad y universalidad de los derechos
2019
Esta tesis aborda el principio de indivisibilidad entre la universalidad de los derechos y los deberes del ser humano apelando a un corolario: el deber de solidaridad. Para ello se analiza el sentido de la noción de solidaridad y la doble tensión en la que se mueve el concepto a través de la dicotomía público/privado y abierto/cerrado que la caracteriza, examinándose las dos dimensiones mutuamente condicionantes que lo componen: la ético-política y la jurídica. Ello nos permite examinar la problemática que encierra la configuración de la solidaridad como un valor jurídico, fuente de deberes también jurídicos, y ponderar la correspondencia entre dignidad, deberes y derechos. Así, primero se …
