A framework for strengthening data ecosystems to serve humanitarian purposes
No full textThe incidence of natural disasters worldwide is increasing. As aresult, a growing number of people is in need of humanitariansupport, for which limited resources are available. This requires aneffective and efficient prioritization of the most vulnerable peoplein the preparedness phase, and the most affected people in theresponse phase of humanitarian action. Data-driven models havethe potential to support this prioritization process. However, theapplications of these models in a country requires a certain level ofdata preparedness. To achieve this level of data preparedness on alarge scale we need to know how to facilitate, stimulate and coor-dinate data-sharing between humanitarian actors. We use a dataecosystem perspective to develop success criteria for establishing a“humanitarian data ecosystem”. We first present the developmentof a general framework with data ecosystem governance successcriteria based on a systematic literature review. Subsequently, theapplicability of this framework in the humanitarian sector is as-sessed through a case study on the “Community Risk Assessmentand Prioritization toolbox” developed by the Netherlands Red Cross.The empirical evidence led to the adaption the framework to thespecific criteria that need to be addressed when aiming to establisha successful humanitarian data ecosystem
J.C. Bach's London keyboard sonatas : style and context
No full textJ. C. Bach's keyboard works include several sets of accompanied sonatas, a genre that enjoyed a wide popularity during the Classical era, but never
found its way into the concert repertoire. The accompanied sonata was a genre meant for domestic performance; the solo keyboard sonata, on
the other hand, was adopted in due course by concert audiences. J. C. Bach composed works within both genres during most of his productive years, and his output constitutes a corpus of remarkable consistency. J. C. Bach's removal to London in 1762 coincided with his clear adoption of a galant style, marked by the Italianate influence, and the abandonment of most Baroque traits. The British milieu provided additional factors: the rise of the pianoforte, a thriving music-publishing market, and a great interest in domestic music making among the affluent classes. These factors marked J. C. Bach's output at various levels. Keyboard works had to conform to the proficiency of the amateur performer, a
fact reflected in the accompanied output mostly. The number of movements, their length, and the inclusion of particular technical devices are readily observable differences between the two genres. The most remarkable
distinction lies perhaps in the preference for binary sonata format in the accompanied. sonatas from the mid 1760s to the 1770s, in spite of a later tendency for tripartite designs in both genres. J. C. Bach's lifelong preference for motivic phrase structure conditioned his keyboard production and partly explains the gap in quality between some of his works and sonatas composed around the same time by Haydn and Mozart, who developed more effective means to connect the melodic material
to higher structural units. J. C. Bach's influence, however, endured in Mozart's handling of melody, and his keyboard production constitutes, in spite of some flaws, a noteworthy example of elegance and craftsmanship
Measurement of the CP-violating phase \phi s in Bs->J/\psi\pi+\pi- decays
No full textMeasurement of the mixing-induced CP-violating phase phi_s in Bs decays is of prime importance in probing new physics. Here 7421 +/- 105 signal events from the dominantly CP-odd final state J/\psi pi+ pi- are selected in 1/fb of pp collision data collected at sqrt{s} = 7 TeV with the LHCb detector. A time-dependent fit to the data yields a value of phi_s=-0.019^{+0.173+0.004}_{-0.174-0.003} rad, consistent with the Standard Model expectation. No evidence of direct CP violation is found

Observation of J/ψ-pair production in pp collisions at √s=7 TeV
No full textThe production of J/ψ pairs in proton–proton collisions at a centre-of-mass energy of 7 TeV has been observed using an integrated luminosity of 37.5 pb−1 collected with the LHCb detector. The production cross-section for pairs with both J/ψ in the rapidity range 2 < yJ/ψ < 4.5 and transverse momentum pJ/ψ T <10 GeV/c is σJ/ψJ/ψ =5.1±1.0±1.1 nb, where the first uncertainty is statistical and the second systematic
Measurement of the cross-section ratio σ(χc2)/σ(χc1) for prompt χc production at √s=7 TeV
No full textThe prompt production of the charmonium χc1 and χc2 mesons has been studied in proton–proton collisions at the Large Hadron Collider at a centre-of-mass energy of . The χc mesons are identified through their decays χc→J/ψγ with J/ψ→μ+μ− using 36 pb−1 of data collected by the LHCb detector in 2010. The ratio of the prompt production cross-sections for the two χc spin states, σ(χc2)/σ(χc1), has been determined as a function of the J/ψ transverse momentum, , in the range from 2 to 15 GeV/c. The results are in agreement with the next-to-leading order non-relativistic QCD model at high and lie consistently above the pure leading-order colour-singlet prediction
What psychological, linguistic and sociobiographical variables power EFL/ESL teachers’ motivation?
No full textThis is a correlational study on the relationship between teachers’
motivation dimensions of intrinsic motivation, identified regulation, introjected regulation, external regulation and amotivation (Fernet et al., 2008), and age, gender, English as L1/LX, English proficiency, global trait emotional intelligence (Trait EI), well-being, emotionality, self-control and sociability (Petrides & Furnham, 2000, 2001). The study builds on existing work on the link between English language teacher emotions and their self-reported classroom behaviour (Dewaele et al., 2018; Dewaele & Mercer, 2018). Through a sociobiographical questionnaire, the short version of the Trait EI questionnaire (TEIQshort form; Petrides, 2009) and the English version of the LEXTALE, the author concludes that motivation is linked with a range of psychological, demographic and linguistic variables, and builds psychological and personality profiles of motivated teachers
Genetic risk and a primary role for cell-mediated immune mechanisms in multiple sclerosis
No full textMultiple sclerosis is a common disease of the central nervous system in which the interplay between inflammatory and neurodegenerative processes typically results in intermittent neurological disturbance followed by progressive accumulation of disability. Epidemiological studies have shown that genetic factors are primarily responsible for the substantially increased frequency of the disease seen in the relatives of affected individuals, and systematic attempts to identify linkage in multiplex families have confirmed that variation within the major histocompatibility complex (MHC) exerts the greatest individual effect on risk. Modestly powered genome-wide association studies (GWAS) have enabled more than 20 additional risk loci to be identified and have shown that multiple variants exerting modest individual effects have a key role in disease susceptibility. Most of the genetic architecture underlying susceptibility to the disease remains to be defined and is anticipated to require the analysis of sample sizes that are beyond the numbers currently available to individual research groups. In a collaborative GWAS involving 9,772 cases of European descent collected by 23 research groups working in 15 different countries, we have replicated almost all of the previously suggested associations and identified at least a further 29 novel susceptibility loci. Within the MHC we have refined the identity of the HLA-DRB1 risk alleles and confirmed that variation in the HLA-A gene underlies the independent protective effect attributable to the class I region. Immunologically relevant genes are significantly overrepresented among those mapping close to the identified loci and particularly implicate T-helper-cell differentiation in the pathogenesis of multiple sclerosis
