Social media as a strategic marketing tool in the Sicilian wine industry: Evidence from Facebook
2017
Abstract Over the last few years, many companies have integrated social media, and social networking sites in particular, into their communication and media plan, leading to a deep transformation of the organizational models and changing the companies׳ marketing dynamics. This study has dual aims: first, to recognize and validate the firm׳s social media (SM) efforts in its use of the Facebook platform; second, to examine the relationships among the firm׳s SM efforts and some firm and managerial characteristics. In order to achieve these research aims, data on 45 wineries were collected and analysed, using a model that considers three different dimensions of the firms׳ activity on the social…
Virtual simulation of an osseointegrated trans-humeral prosthesis: A falling scenario
2018
Abstract Introduction Traditional prosthetic solutions expose the amputee to numerous problems that limit his ability to safely perform the normal activities of daily life. In order to eliminate the problems related to the use of the traditional prosthesis with socket, a new technique was developed for fixing the prosthesis to the amputees based on the principle of osseointegration. The aim of this paper is to study and analyze the stress distribution on the interface between a trans-humeral osseointegrated prosthetic implant and the residual bone, identifying the most stressed areas and thus foreseeing possible failure phenomena of the entire prosthetic system and, after, to compare the st…
Plant hunting: exploring the behaviour of amateur botanists in the field
2021
We asked what are the behavioural and logistic preferences of professional and amateur botanists when exploring flora in the field. We extracted temporal and spatial data on vas- cular plant species occurrences from three datasets of Sicilian flora: a subset of iNaturalist, a dataset collected by a Facebook group focused on the flora of Sicily and a subset of the professional database European Vegetation Archive. We used the time span of individual contributor’s activity as a proxy of their commitment to collecting information about the flora of Sicily. Climate and landscape data were used to better characterize the spatial and temporal activity of data contributors. Finally, we assessed wh…
Permian-Cenozoic deep-water carbonate rocks of the Southern Tethyan Domain. The case of Central Sicily
2016
We present an integrated stratigraphy of the outcropping and buried Permian-Cenozoic deep-water carbonate successions, forming some of the tectonic units mostly buried beneath the Late Neogene sedimentary cover in the fold and thrust belt of Central Sicily. Three main successions, pertaining to the well known Lercara, Imerese and Sicanian domains, have been reconstructed on the basis of a detailed facies analysis, seismostratigraphic interpretation, bio -stratigraphy (mostly based on palynological data) and comparison between outcropping and subsurface deep-water sediments. The main results reveal a continuous sedimentation of the deep-water Southern Tethyan Sicilian succession since the Pe…
Information disorder. Learning to recognize fake news
2022
The advent of the internet and digital platforms has revolutionised the way information is produced and disseminated. The aim of this paper was to examine whether it is possible to draw from Article 21 of the Italian Constitution that there is a right to good information, as an expression of the rights to be informed and to receive information. It also looked at what form of regulation is possible for the dissemination of information on the Web in order to ensure that it is true, objective, and unbiased and whether public- only regulation, private- only regulation or a form of co- regulation, which seems to be model chosen in the EU’s draft Regulation, the so- called Digital Services Act, i…
GDPR piekļuves tiesību sistēma UBER platformai
2019
Vispārējā datu aizsardzības regula (turpmāk tekstā – GDRP) ir regula, kuras mērķis ir nodrošināt un veicināt personas datu privātumu. Regula stājās spēkā 2018. gada 25. maijā. Visiem uzņēmumiem, kuri pārvalda Eiropas pilsoņu datus, bija jāievieš jaunu noteikumu kopumu. Viens no svarīgākajiem GDPR noteikumiem bija piekļuves tiesību noteikums. Tas dod datu subjektiem tiesības saņemt no kontroliera apstiprinājumu par to, vai tiek apstrādāti personas dati, kas attiecas uz subjektu, un, ja kontrolieris apstrādā subjekta personas datus, dod subjektam piekļuvi tiem. UBER ieņem vadošo pozīciju transporta nozarē. UBER dod iespēju lietotājam organizēt un plānot pārvadājumus. Lai saglabātu augstu pozī…
Game-based learning supported by audience response tools: game proposals and preliminary assessment
2018
The so-called game-based learning strategies are based on introducing games in the classrooms to improve aspects such as student performance, concentration and effort. Currently, they provide a very useful resource to increase the motivation of university students, generating a better atmosphere among peers and between student and teacher, which in turn is generally translated into better academic results. However, the design of games that successfully achieve the desired teaching-learning objectives is not a trivial task. This work focuses on the design of games that allow the assessment of ICT-related university subjects. Specifically, three different games are proposed, all based on stud…
Postural balance and self-reported functional ability in 75-year-old men and women: a cross-national comparative study.
1997
OBJECTIVE To study postural balance in relation to self-reported functional ability (mobility and ADL) and general physical activity in elderly men and women living in three different Nordic environments. PARTICIPANTS A random sample of 448 men and 556 women from among the 75-year-old residents in Glostrup, Denmark, and Goteborg, Sweden, and all the residents of relevant age (127 men and 261 women) in Jyvaskyla, Finland. MEASUREMENTS Assessment of postural balance with eyes open and closed using a piezoelectric force platform. A structured interview on self-reported functional ability and physical activity. An in-laboratory medical examination. RESULTS In spite of some differences in balanc…
Biomechanical analysis of anticipation of elite and inexperienced goalkeepers to distance shots in handball
2012
AbstractThe objective of this study was to evaluate the anticipation time and kinematic factors in the movement ofgoalkeepers’ center of mass when making a long-distance throw in handball. The sample group was composed of 14goalkeepers and field players. A force platform was used to measure the force of the goalkeepers’ reaction movements, whilethe throwers’ movements were recorded with high-speed cameras. The expert goalkeepers began to move 193 ± 67 ms beforethe ball was released, with a 67% success rate of interception. The inexperienced goalkeepers began their movement 209 ±127 ms with a 24% success rate. The time taken by expert goalkeepers to begin a vertical movement of their CM, rel…
Potencialidades de Google Maps en la investigación social aplicada
2019
In recent years, Google has devoted resources to build a complete map of the world. They constantly scan the territory, collecting a large amount of data that provides updated and complete geographic information. This allows us to have an interoperable map that provides the end user with a search tool, not only of routes but also of shops, equipment and any type of geo-referenced information. In addition, Google Maps provides a series of Application Programming Interface (API), which provides a library of set of subroutines, functions and procedures (in object-oriented programming) that can be used by other software to automate the extraction of information of the Google platform. These fre…
