We report the status and progress of the Heavy Flavour Averaging Group work on the global fit of τ tau lepton branching fractions, on the lepton universality tests and on the measurement of the Cabibbo-Kobayashi-Maskawa matrix element |Vus| using τ lepton measurements. We also review the prospects for improving the precision of the |Vus| measurement.

We report the status of the Heavy Flavour Averaging Group (HFLAV) averages of the \tauτ lepton measurements We then update the latest published HFLAV global fit of the \tauτ lepton branching fractions (Spring 2017) with recent results by . We use the fit results to update the Cabibbo-Kobayashi-Maskawa (CKM) matrix element \left|V_{us}\right||Vus| measurements with the \tauτ branching fractions. We combine the direct \tauτ branching fraction measurements with indirect predictions using kaon branching fractions measurements to improve the determination of \left|V_{us}\right||Vus| using \tauτ branching fractions. The \left|V_{us}\right||Vus| determinations based on the inclusive branching fraction of \tauτ to strange final states are about 3\sigma3σ lower than the \left|V_{us}\right||Vus| determination from the CKM matrix unitarity.

The Status

This paper gives an account of a teacher preparation program in which a problem based learning approach was used to enact inclusive learning among student teachers. Taking a postmodernist perspective, the student teachers' experiences of participation in group activities on a problem-based scenario in an Australian university was documented through chat-rooms, online postings and reflective journal writings. Knowledge about peer interaction and communities of learning relationship, reflective practice and opportunity to manage difference and question the status quo are areas that were highlighted by the students. We concluded that problem-based learning is transformative and that whatever teacher educators expect their student teachers to do in their teaching contexts when they graduate, they need to give them the opportunity to practise these in their learning during training.

AbstractThis paper reports world averages of measurements of b-hadron, c-hadron, and $$\tau $$ τ -lepton properties obtained by the Heavy Flavour Averaging Group using results available through September 2018. In rare cases, significant results obtained several months later are also used. For the averaging, common input parameters used in the various analyses are adjusted (rescaled) to common values, and known correlations are taken into account. The averages include branching fractions, lifetimes, neutral meson mixing parameters, $$C\!P$$ C P  violation parameters, parameters of semileptonic decays, and Cabibbo–Kobayashi–Maskawa matrix elements.

Global Fit

I summarize the theoretical progress in the determination of the CKM elements since Lepton-Photon 2003 and present the status of the elements and parameters of the Cabibbo-Kobayashi-Maskawa (CKM) matrix. One finds |Vus| = 0.2227 ± 0.0017 from K and τ decays and |Vcb| = (41.6 ± 0.5) · 10-3 from inclusive semileptonic B decays. The unitarity triangle can now be determined from tree-level quantities alone and the result agrees well with the global fit including flavour-changing neutral current (FCNC) processes, which are sensitive to new physics. From the global fit one finds the three CKM angles θ12 = 12.9° ± 0.1°, θ23 = 2.38° ± 0.03° and θ13 = 0.223° ± 0.007° in the standard PDG convention. The CP phase equals [Formula: see text] at 1σ CL and [Formula: see text] at 2σ CL. A major progress are first results from fully unquenched lattice QCD computations for the hadronic quantities entering the UT fit. I further present the calculation of three-loop QCD corrections to the charm contribution in [Formula: see text] decays, which removes the last relevant theoretical uncertainty from the [Formula: see text] system. Finally I discuss mixing-induced CP asymmetries in [Formula: see text] penguin decays, whose naive average is below its Standard Model value by 3σ.

The development of increasingly advanced education requires teachers to be professional in carrying out learning. In linewith that, the researcher applied learning through the tourism work method as an effort to improve social studies learningoutcomes of Indonesian culture material in the fifth-grade students of SD Negeri 002 Kuok Kecamatan Kuok. This study usesa class action research method with 27 research subjects consisting of 10 men and 17 women, two months of research. Thereare three research data, namely observation, group activities, and learning outcomes tests. The implementation of learning inthis study was two cycles and each surplus was held twice this meeting had an increase in the fourth cycle as in the learningprocess for very good student scores as much as 50.37%, both as much, 35.56% and enough as many as 14, 07%. While theresults of group work have increased as seen in the second cycle of the fourth meeting, namely: for very good student gradesas much as 65.47%, both as much, 34.52% and enough as much as 0%. From the learning outcomes, it can also be seen thecompleteness in the second cycle, namely the classical completeness of 92.59% and the incomplete 7.41%.

AbstractEmployers of business graduates require them to be effective communicators and team members in twenty-first century work environments. As a means of developing these skills, we believe group work is important to an undergraduate business teaching pedagogy preparing graduates for the challenges of modern workplaces. Student responses to a series of qualitative and quantitative focus group activities highlighted the ‘big issues’ encountered in group activities involving an increasingly internationalised and diverse cohort of students. These issues related mainly to communication within the group and the fear of social-loafers. These insights established the basis on which proactive strategies were introduced in a subsequent teaching period to nurture and advance the quality of the learning experience within a tertiary undergraduate business education setting. Given that reduced Government funding to Australian universities has prompted the management of institutions to look to full-fee paying international students to offset shortfalls in their operating budgets, this paper explores the particular impact of increasing numbers of English as a Second Language (ESL) students on the quality of, and student receptiveness to, group based study activities.
