Abstract: Air-based respiration limits the use of aquatic environments by ancestrally terrestrial animals. To overcome this challenge, diving arthropods have evolved to respire without resurfacing using air held between their cuticle and surrounding water. Inspired by natural history observations in Haiti (DLM & REG pers. obs.) and Costa Rica, we conducted experiments documenting routine air-based underwater respiration in several distantly-related semi-aquatic Anolis lizard species. Semi-aquatic anoles live along neotropical streams and frequently dive for refuge or food, remaining underwater for up to 18 minutes. While submerged, these lizards iteratively expire and re-inspire narial air bubbles – underwater “rebreathing.” Rebreathed air is used in respiration, as the partial pressure of oxygen in the bubbles decreases with experimental submersion time in living anoles but not in mechanical controls. Non-aquatic anoles occasionally rebreathe when submerged but exhibit more rudimentary rebreathing behaviors. Anole rebreathing is facilitated by a thin air layer (i.e., a “plastron”, sensu Brocher) supported by the animal’s rugose skin upon submergence. We suggest that hydrophobic skin, which we observed in all sampled anoles, may have been exaptative, facilitating the repeated evolution of specialized rebreathing in species that regularly dive. Phylogenetic analyses strongly suggest that specialized rebreathing is adaptive for semi-aquatic habitat specialists. Air-based rebreathing may enhance dive performance by incorporating dead space air from the buccal cavity or plastron into the lungs, facilitating clearance of carbon dioxide, or allowing uptake of oxygen from surrounding water (i.e., a “physical gill” mechanism)
Differences in financing of paralympic sport boccia in selected contries
No full textThis thesis deals with the financing of the Paralympic sport of boccia. The main objective is to compare the financing of the federations in the Czech Republic with foreign countries. To compare our sources of funding against Slovakia, UK and Portugal in the sport of boccia. The research is based on the analysis of publicly available data, annual reports, official documents and communication with national sports federations. The results show significant differences in the diversity and stability of funding models, with the Czech Republic and Slovakia more dependent on public subsidies, while the UK and Portugal use a wider range of sources.

Internship at USA Boccia
No full textThis precision-throwing sport has a combination of strategic thinking elements of bocce ball, chess, and curling. Rules for wheelchair-bound and seated athletes are determined from a classification system, which is based on athletes’ level of disability. Contested at the local, regional, national, and international levels, multi-sport organization USCPAA founded boccia in the early 1980s. By 2008, boccia grew at the global scale in over fifty countries. As one of only three paralympic sports that do not have a counterpart in the Olympics, boccia is governed by the Boccia International Sports Federation (BISFed). After several organizational transitions for the previous decade, USA Boccia became a national governing organization (NGO) in 2015. This NGO provides athletes with disabilities the opportunity to compete in boccia from the local to pipeline international competitions. USA Boccia’s mission is to expand the sport of boccia nationwide in the United States through development, growth, and promotion.
As a graphic design intern for USA Boccia — the national governing organization for Paralympics boccia — I typically included the logo’s color scheme in all projects as one of the aspects for my own visual guidelines, which varied based on the assigned project. There were a few instances, however, when I varied this color palette to complement elements in a layout. USA Boccia’s logo was a necessity and served as a visual motif throughout my projects — for print or digital. Although I mostly had the creative freedom towards layout creation, I made sure to include USA Boccia’s photographs whenever possible to avoid misappropriation. When I would employ photographs outside of USA Boccia, I always checked to confirm if a photograph was under the Creative Commons license and did not include human subjects unaffiliated with USA Boccia. Lastly, I based my chosen typography on readability

Teoria e metodologia per la ricerca sul web sociale: tra Big Data e Deep Data
No full textContent created by users online (UGC) is a new kind of research topic in the field of social sciences and it gives us particularly promising data. Defined as qualitative data, it is undeniable that being spontaneously created by the users for an unknown audience places them in a particular condition. In addition to it we have to consider the consequences, for the empirical research, of the ease with which those data are researched and found. This paper focuses on how Big Data are changing the way we are thinking and conducting the research. They lead us to the Computational Social science, which enables a transdisciplinary approach: a sociological observation of online social phenomena using methods of data managing and data collection borrowed from the computer science. As a consequence, we are able to analyze in depth a wide range of data as never before, facing a scenario rich both of opportunities and critical points to not understate. It is necessary, at this point, to keep clear in mind structures and affordances of the platforms, characteristics of the analyzed network, the relation between online conversations and social ties and in the end, all of the previous points have to be framed in a longitudinal perspective in order not to push down the data in an eternal present avoiding to consider their evolution over time

Gli effetti sociali del web
No full textSocial television, cerimonie mediali online, comunità di pratica che si formano su Internet attorno a politica, lavoro, educazione, informazione e intrattenimento sono alcuni dei luoghi e delle forme che il volume analizza.
La sfida è però più radicale e profonda e ha a che fare con gli approcci metodologici che rendono possibile osservare e interpretare la realtà che scorre tra vita sociale e Rete. Dal contributo delle scienze sociali computazionali e degli Internet Studies a quello della sociologia visuale applicata ai Social Network, gli autori mostrano come sia possibile oggi innovare la ricerca sociale e tentare di dischiudere gli effetti sociali del web.
Rivolto a chi voglia capire la trasformazione in atto nel mondo della ricerca e della formazione, il volume è un valido strumento anche per quei professionisti che lavorano nella realtà televisiva e dei media audiovisivi così come nell'ambito dei consumi
