Tensions on Finnish Constitutional Bilingualism in Neo-nationalist Times : Constructions of Swedish in Monolingual and Bilingual Contexts
2020
This chapter analyses the tensions on the status of Finnish constitutional bilingualism from the perspective of higher education, more precisely from the position of Swedish in one monolingually Swedish university (Åbo Akademi University [ÅAU]) and one bilingual university (University of Helsinki [UH]). It contributes to an understanding of the position of minority languages in universities in times when the use of English has increased on one hand and neo-nationalist tendencies stressing the importance of national language(s) are on the rise on the other. Apparently, the new bilingual programmes at UH challenge the tradition of institutional separation of national languages. At ÅAU, in tur…
Kunnon muslimi ja kunnon kansalainen : turkkilaisten imaamisaarnaajalukioiden oppikirjojen ilmentämän maailmankatsomuksen analyysi
2017
This qualitative study aims to analyse the worldview that emerges in the textbooks of Turkish imam and preacher high schools (úmam hatip lisesi). The study material consists of eight textbooks that belong to the vocational religious education of Turkish imams. All of the textbooks were published around 2010. In this study, theoretical considerations regarding the essence of worldview (Weltanschauung) are summarized into an existential model of worldview (EKMA). The model provides two viewpoints from which to understand the worldview under study. The first viewpoint concentrates on understanding the worldview’s belief structure and the content of those beliefs. The second viewpoint examines …
Long-baseline neutrino oscillation physics potential of the DUNE experiment
2020
The sensitivity of the Deep Underground Neutrino Experiment (DUNE) to neutrino oscillation is determined, based on a full simulation, reconstruction, and event selection of the far detector and a full simulation and parameterized analysis of the near detector. Detailed uncertainties due to the flux prediction, neutrino interaction model, and detector effects are included. DUNE will resolve the neutrino mass ordering to a precision of 5σσ, for all δCPδCP values, after 2 years of running with the nominal detector design and beam configuration. It has the potential to observe charge-parity violation in the neutrino sector to a precision of 3σσ (5σσ) after an exposure of 5 (10) years, for 50% o…
Observation of Astrophysical Neutrinos in Four Years of IceCube Data
2015
The spectrum of cosmic rays includes the most energetic particles ever observed. The mechanism of their acceleration and their sources are, however, still mostly unknown. Observing astrophysical neutrinos can help solve this problem. This update extends the data-taking period by one more year to four years from 2010 to 2014 for a total livetime of 1347 days.
IceCube-22 Solar WIMP Data: Searching for Muon Neutrinos from Dark Matter Annihilations in the Sun
2009
Relic dark matter in the galactic halo may become gravitationally trapped in the Sun and accumulate in its center, where it can annihilate each other, producing standard model particles, which may decay creating neutrinos. A search was performed using data from the IceCube detector in its 22 string configuration. The experimental dataset consists of 104.26 days livetime, corresponding to a set of runs recorded during the period when the Sun was below the horizon at the South Pole, between March 21st and September 23rd.
Astrophysical muon neutrino flux in the northern sky with 2 years of IceCube data
2015
Results from the IceCube Neutrino Observatory have recently provided compelling evidence for the existence of a high energy astrophysical neutrino flux utilizing a dominantly Southern Hemisphere data set consisting primarily of νe and ντ charged-current and neutral-current (cascade) neutrino interactions. Additionally, a fit for an astrophysical flux with an arbitrary spectral index is performed.
Search for contained neutrino events at energies above 30 TeV in 2 years of data
2013
Neutrino observations are a unique probe of the universe's highest energy phenomena: neutrinos are able to escape from dense environments that photons cannot and are unambiguous tracers of hadronic interaction processes, in particular the acceleration of cosmic rays. We report on results of an all-sky search for these neutrinos at energies above 30 TeV in the cubic kilometer antarctic IceCube observatory between May 2010 and May 2012. The search follows up on the previous detection of two PeV neutrino events, with improved sensitivity and extended energy coverage down to approximately 30 TeV.
IceCube-40 String Data: Searching for a Diffuse Flux of Astrophysical Muon Neutrinos
2011
One of the main strategies used to look for astrophysical neutrinos with IceCube is the search for a diffuse flux of high-energy neutrinos from unresolved sources. A search was performed using data from the IceCube detector collected in its half completed configuration in which 40 strings operated between April 2008 and May 2009. 12,877 candidate neutrino events were obtained from this data sample.
Search for contained neutrino events at energies greater than 1 TeV in 2 years of data
2015
The IceCube Neutrino Observatory was designed primarily to search for high-energy (TeV--PeV) neutrinos produced in distant astrophysical objects. Here we present the results of a search for neutrino interactions inside IceCube's instrumented volume between 1 TeV and 1 PeV in 641 days of data taken from 2010--2012. From these data we derive new constraints on the diffuse astrophysical neutrino spectrum,as well as the strongest upper limit yet on the flux of neutrinos from charmed-meson decay in the atmosphere.
Search for sterile neutrinos with one year of IceCube data
2016
The IceCube neutrino telescope at the South Pole has measured the atmospheric muon neutrino spectrum as a function of zenith angle and energy to search for the oscillation signatures of light sterile neutrinos. The primary result of this search derives from the first year of data, taken during 2011, of the full 86-string IceCube configuration.
