Joomla! e Microweb: soluzioni low cost per la piccola impresa

Il presente elaborato, "Joomla! e Microweb: soluzioni low cost per la piccola impresa", si pone l'obiettivo di unire un insieme di realtà differenti tra loro: esigenze economiche, piattaforme tecniche e rete sociale possono integrarsi in un circuito virtuoso. Attraverso l'analisi della piattaforma CMS Joomla!, e la sua integrazione con utilities di terze parti, è possibile velocizzare senza perdere qualità, abbattendo i costi, il processo di pubblicazione e mantenimento di un sito web. Attraverso, poi, un'efficace integrazione di Joomla! con servizi social integrati nella piattaforma stessa, è possibile venire in contatto con quelli che vengono definiti gli hub concettuali della rete, come Facebook e YouTube. Mirate politiche di marketing, soprattutto per i prodotti di nicchia, possono essere quindi portate a termine con soddisfazione senza cadere in costi eccessivamente elevati. Infine, è stato coniato il concetto di "Microweb" che sintetizza nel suo significato il processo di integrazione di servizi social e di utilities in un'unica piattaforma madre, nel caso specifico Joomla!.

Tracce di cinefilia su Facebook

La mia tesi approfondisce le dinamiche della cinefilia su Facebook: quali relazioni s'instaurano tra lo spettatore cinefilo, e dunque il suo particolare sguardo, e la moltitudine di frammenti di cinema dispersi nella rete; come si sono modificati i rapporti, gli atteggiamenti, i processi di negoziazione, le abitudini e soprattutto i discorsi dei cinefili al cospetto di tracce di cinema sui social network e in particolare su Facebook. Inoltreprovo a dimostrare che la cinefilia è un'esperienza costitutivamente autobiografica, cui il web permette il perpetuare potenzialmente infinito della (auto)narrazione di sé.

Evaluation of new HTTP Adaptive Streaming algorithms: the clients’ and network’s perspectives

Lo streaming è una tecnica per trasferire contenuti multimediali sulla rete globale, utilizzato per esempio da servizi come YouTube e Netflix; dopo una breve attesa, durante la quale un buffer di sicurezza viene riempito, l'utente può usufruire del contenuto richiesto. Cisco e Sandvine, che con cadenza regolare pubblicano bollettini sullo stato di Internet, affermano che lo streaming video ha, e avrà sempre di più, un grande impatto sulla rete globale. Il buon design delle applicazioni di streaming riveste quindi un ruolo importante, sia per la soddisfazione degli utenti che per la stabilità dell'infrastruttura. HTTP Adaptive Streaming indica una famiglia di implementazioni volta a offrire la migliore qualità video possibile (in termini di bit rate) in funzione della bontà della connessione Internet dell'utente finale: il riproduttore multimediale può cambiare in ogni momento il bit rate, scegliendolo in un insieme predefinito, adattandosi alle condizioni della rete. Per ricavare informazioni sullo stato della connettività, due famiglie di metodi sono possibili: misurare la velocità di scaricamento dei precedenti trasferimenti (approccio rate-based), oppure, come recentemente proposto da Netflix, utilizzare l'occupazione del buffer come dato principale (buffer-based). In questo lavoro analizziamo algoritmi di adattamento delle due famiglie, con l'obiettivo di confrontarli su metriche riguardanti la soddisfazione degli utenti, l'utilizzo della rete e la competizione su un collo di bottiglia. I risultati dei nostri test non definiscono un chiaro vincitore, riconoscendo comunque la bontà della nuova proposta, ma evidenziando al contrario che gli algoritmi buffer-based non sempre riescono ad allocare in modo imparziale le risorse di rete.

Remembering Lee Metcalf - Natural Resources, Environmental and Conservation Excerpts (done for 75th Anniversary of Montana State Parks System - 2014)

Montana's Lee Metcalf was an extraordinary Montana leader with an unbelievable record of accomplishment fighting for the little people against the forces of economic and political power. The public memory is so short that this film will serve to help reacquaint Lee & Donna Metcalf to most of those who were around during their time. But it will also provide an opportunity for new generations to receive a perspective of an important leader from an important time. (Language from YouTube version of the film, written and provided by Executive Producer Evan Barrett) Lee Warren Metcalf (January 28, 1911 – January 12, 1978) was an American lawyer, judge, and politician. A member of the Democratic Party, he served as a U.S. Representative (1953–1961) and a U.S. Senator (1961–1978) from Montana. He was permanent acting President pro tempore of the Senate, the only person to hold that position, from 1963 until his death in 1978.

Tracking Montana’s Groundwater: 20 Years of Lessons Learned

Long-term water-level measurements provide a fundamental indicator of the health of Montana's groundwater resources. For more than 20 years the Groundwater Assessment Program has monitored groundwater levels across the state. This lecture reviews the State's groundwater use and shows how climate variability, groundwater development, and land-use has impacted different aquifers.

Remembering Lee Metcalf

Abstract Montana's Lee Metcalf was an extraordinary Montana leader with an unbelievable record of accomplishment fighting for the little people against the forces of economic and political power. The public memory is so short that this film will serve to help reacquaint Lee & Donna Metcalf to most of those who were around during their time. But it will also provide an opportunity for new generations to receive a perspective of an important leader from an important time. (Language from YouTube version of the film, written and provided by Executive Producer Evan Barrett) Lee Warren Metcalf (January 28, 1911 – January 12, 1978) was an American lawyer, judge, and politician. A member of the Democratic Party, he served as a U.S. Representative (1953–1961) and a U.S. Senator (1961–1978) from Montana. He was permanent acting President pro tempore of the Senate, the only person to hold that position, from 1963 until his death in 1978. U.S. House of Representatives During his tenure in the House, Metcalf served on the Education and Labor Committee (1953–1959), Interior and Insular Affairs Committee (1955–1959), Select Astronautics and Space Exploration Committee (1958), and Ways and Means Committee (1959–1960). He became known as one of Congress's "Young Turks" who promoted liberal domestic social legislation and reform of congressional procedures. He introduced legislation to provide health care to the elderly ten years before the creation of Medicare. He earned the nickname "Mr. Education" after sponsoring a comprehensive bill providing for federal aid to education. He also voted against legislation that would have raised grazing permits on federal lands, and led the opposition to a bill that would have swapped forested public lands for cutover private lands. He was elected chairman of the Democratic Study Group in 1959. U. S. Senate Regarded as "a pioneer of the conservation movement", Metcalf worked to protect the natural environment and regulate utilities. He helped pass the Wilderness Act of 1964, and supported the creation of the Great Bear Wilderness and the Absaroka-Beartooth Wilderness. In 1962, he introduced a "Save Our Streams" bill to preserve natural recreation facilities and protect fish and wildlife from being destroyed by highway construction. He was a longtime member of the Migratory Bird Conservation Commission. He was also active on the issue of education. He was a leading supporter of the Elementary and Secondary Education Act, the effort to extend the G.I. Bill's educational benefits to a new generation of veterans, and the development of legislation to improve federally-aided vocational education.[1] The Peace Corps was established under leadership of Metcalf and Senator Mansfield. In 1983, by act of Congress, the Lee Metcalf Wilderness area was created in southwestern Montana in honor of the late Congressman. The Great Bear Wilderness and Absaroka-Beartooth Wilderness areas were also created as a result of Metcalf's efforts in Congress, in addition to the Lee Metcalf National Wildlife Refuge in Montana. Metcalf was ranked number 15 on a list of the 100 Most Influential Montanans of the Century by the Missoulian newspaper.

Always on: Cybermobbing in der modernen Gesellschaft

Cybermobbing ist ein brisantes Thema, das seit über einem Jahrzehnt weltweit für Aufsehen sorgt. Es handelt sich um eine elektronische Mobbingvariante, die vom Versenden einer beleidigenden SMS bis hin zum Veröffentlichen von peinlichen Videos auf YouTube oder Facebook geht. Cybermobbing kann als ungünstiges Nebenprodukt des gesellschaftlichen Wandels hin zur digitalen Kommunikation gesehen werden. Cybermobbing ist deswegen nicht nur ein individuelles, sondern auch ein gesellschaftliches Problem, das in diesem größeren Rahmen betrachtet werden muss. Sowohl das Individuum als auch die Familie, die Gleichaltrigen, die Schule und der gesellschaftliche Kontext sind wichtige Akteure einerseits bei Entstehung und Aufrechterhaltung von Cybermobbing, andererseits bei dessen Prävention und Intervention.

"Two hundred ninety-four": Remediation and multimodal performance in tourist placemaking

We offer here a multimodal discourse analysis of a range of verbal (writing and speech), nonverbal (movement and gesture) and technological (photography and video) resources used by tourists at the Leaning Tower of Pisa. In doing so, we pin-point the recycling and layering of mediatized representations (e.g. guidebooks and official brochures), mediated actions (e.g. climbing the Tower or posing in front of it), and remediated practices (e.g. posting a YouTube video of oneself climbing the 294 steps to the top of the Tower). Through this kind of empirically-based examination of tourists’ discursive and embodied performances – their ways of talking about and behaving in spaces – we witness how people never simply visit places but are always actively shaping and making these places. The Leaning Tower of Pisa is, therefore, as much an emergent production of the tourist imagination as it is a pre-existing, lop-sided construction of stone.

Persistent Caching in Information-Centric Networks

Information-centric networking (ICN) is a new communication paradigm that aims at increasing security and efficiency of content delivery in communication networks. In recent years, many research efforts in ICN have focused on caching strategies to reduce traffic and increase overall performance by decreasing download times. Since caches need to operate at line speed, they have only a limited size and content can only be stored for a short time. However, if content needs to be available for a longer time, e.g., for delay-tolerant networking or to provide high content availability similar to content delivery networks (CDNs), persistent caching is required. We base our work on the Content-Centric Networking (CCN) architecture and investigate persistent caching by extending the current repository implementation in CCNx. We show by extensive evaluations in a YouTube and webserver traffic scenario that repositories can be efficiently used to increase content availability by significantly increasing cache hit rates.
