Influencia de las redes sociales en la creación y mantención del capital social en Chile

Seminario para optar al grado de Ingeniero Comercial, Mención AdministraciónNo autorizada por los autores para ser publicada a texto completoEl presente trabajo se replicó el estudio realizado por Ellison , Steinfield y Lampe (2007) sobre el uso de redes sociales y su influencia dentro del capital social. Este estudio original se centro en estudiar alumnos de la Universidad de Michigan, Estados Unidos, en su uso de Facebook y la influencia que tuvo en la mantención y creación del capital social de estos individuos. En este estudio se buscó testear las mismas hipótesis del trabajo original pero ahora adaptadas en la realidad social de Chile, utilizando una muestra de 546 alumnos de 1 a 5 año de la Facultad de Economía y Negocios de la Universidad de Chile. Para obtener respuestas más precisas en esta oportunidad se ampliaron las redes sociales investigadas, a Facebook ya analizada en el trabajo original, se le agregaron las redes sociales con mayor crecimiento durante el ultimo tiempo: Twitter y LinkedIn. Al testear, analizar, tabular y realizar regresiones a los resultados de la encuesta realizada, se tuvo resultados similares al trabajo original, inclusive en el caso de Facebook se vio mucho más potenciada. En las otras dos redes sociales también se cumplió la hipótesis generada, pero con una menor intensidad. Estos resultados terminan siendo consistentes con los encontrados en el trabajo original del cual se basa este informe. El estudio muestra que el uso de las redes sociales afecta positivamente a mantener y crear los distintos tipos de capital social (ya sea puente o vínculo), junto con los índices de felicidad tales como la satisfacción con la vida universitaria y el grado de autoestima

High-energy and ultra-high-energy neutrinos: A Snowmass white paper

Astrophysical neutrinos are excellent probes of astroparticle physics and high-energy physics. With energies far beyond solar, supernovae, atmospheric, and accelerator neutrinos, high-energy and ultra-high-energy neutrinos probe fundamental physics from the TeV scale to the EeV scale and beyond. They are sensitive to physics both within and beyond the Standard Model through their production mechanisms and in their propagation over cosmological distances. They carry unique information about their extreme non-thermal sources by giving insight into regions that are opaque to electromagnetic radiation. This white paper describes the opportunities astrophysical neutrino observations offer for astrophysics and high-energy physics, today and in coming years

Clinical and genetic characteristics of late-onset Huntington's disease

Background: The frequency of late-onset Huntington's disease (>59 years) is assumed to be low and the clinical course milder. However, previous literature on late-onset disease is scarce and inconclusive. Objective: Our aim is to study clinical characteristics of late-onset compared to common-onset HD patients in a large cohort of HD patients from the Registry database. Methods: Participants with late- and common-onset (30–50 years)were compared for first clinical symptoms, disease progression, CAG repeat size and family history. Participants with a missing CAG repeat size, a repeat size of ≤35 or a UHDRS motor score of ≤5 were excluded. Results: Of 6007 eligible participants, 687 had late-onset (11.4%) and 3216 (53.5%) common-onset HD. Late-onset (n = 577) had significantly more gait and balance problems as first symptom compared to common-onset (n = 2408) (P <.001). Overall motor and cognitive performance (P <.001) were worse, however only disease motor progression was slower (coefficient, −0.58; SE 0.16; P <.001) compared to the common-onset group. Repeat size was significantly lower in the late-onset (n = 40.8; SD 1.6) compared to common-onset (n = 44.4; SD 2.8) (P <.001). Fewer late-onset patients (n = 451) had a positive family history compared to common-onset (n = 2940) (P <.001). Conclusions: Late-onset patients present more frequently with gait and balance problems as first symptom, and disease progression is not milder compared to common-onset HD patients apart from motor progression. The family history is likely to be negative, which might make diagnosing HD more difficult in this population. However, the balance and gait problems might be helpful in diagnosing HD in elderly patients
