Abstract

The NA48/2 experiment at CERN reports the first observation of the $K^{\pm} \rightarrow \pi^{0} \pi^{0} \mu^{\pm} \nu$ decay based on a sample of 2437 candidates with 15% background contamination collected in 2003--2004. The decay branching ratio in the kinematic region of the squared dilepton mass above $0.03$~GeV$^2/c^4$ is measured to be $(0.65 \pm 0.03) \times 10^{-6}$. The extrapolation to the full kinematic space, using a specific model, is found to be $(3.45 \pm 0.16) \times 10^{-6}$, in agreement with chiral perturbation theory predictions., Comment: 16 pages, 9 figures

Abstract

The NA48/2 Collaboration at CERN has accumulated unprecedented statistics of rare kaon decays in the Ke4 modes: Ke4(+-) ($K^\pm \to \pi^+ \pi^- e^\pm \nu$) and Ke4(00) ($K^\pm \to \pi^0 \pi^0 e^\pm \nu$) with nearly one percent background contamination. The detailed study of form factors and branching rates, based on these data, has been completed recently. The results brings new inputs to low energy strong interactions description and tests of Chiral Perturbation Theory (ChPT) and lattice QCD calculations. In particular, new data support the ChPT prediction for a cusp in the $\pi^0\pi^0$ invariant mass spectrum at the two charged pions threshold for Ke4(00) decay. New final results from an analysis of about 400 $K^\pm \to \pi^\pm \gamma \gamma$ rare decay candidates collected by the NA48/2 and NA62 experiments at CERN during low intensity runs with minimum bias trigger configurations are presented. The results include a model-independent decay rate measurement and fits to ChPT description., Comment: XIIth International Conference on Heavy Quarks and Leptons 2014, Mainz, Germany

Abstract

The NA48/2 Collaboration at CERN has accumulated and analysed unprecedented statistics of rare kaon decays in the $K_{e4}$ modes: $K_{e4}(+-)$ ($K^\pm \to \pi^+ \pi^- e^\pm \nu$) and $K_{e4}(00)$ ($K^\pm \to \pi^0 \pi^0 e^\pm \nu$) with nearly one percent background contamination. It leads to the improved measurement of branching fractions and detailed form factor studies. New final results from the analysis of 381 $K^\pm \to \pi^\pm \gamma \gamma$ rare decay candidates collected by the NA48/2 and NA62 experiments at CERN are presented.

Abstract

From the 2002 data taking with a neutral kaon beam extracted from the CERN-SPS, the NA48/1 experiment observed 97 $\Xi^{0}\rightarrow \Sigma^{+} \mu^{-} \bar{\nu}_{\mu}$ candidates with a background contamination of $30.8 \pm 4.2$ events. From this sample, the BR($\Xi^{0}\rightarrow \Sigma^{+} \mu^{-} \bar{\nu}_{\mu}$) is measured to be $(2.17 \pm 0.32_{\mathrm{stat}}\pm 0.17_{\mathrm{syst}})\times10^{-6}$.

Abstract

As first observed by the NA48/2 experiment at the CERN SPS, the $\p0p0$ invariant mass (M00) distribution from $\kcnn$ decay shows a cusp-like anomaly at M00=2m+, where m+ is the charged pion mass. An analysis to extract the pi pi scattering lengths in the isospin I=0 and I=2 states, a0 and a2, respectively, has been recently reported. In the present work the Dalitz plot of this decay is fitted to a new empirical parameterization suitable for practical purposes, such as Monte Carlo simulations of K+- -> pi+- pi0 pi0 decays., Comment: 9 pages, 3 figures.

18. Challenges of Student Selection: Predicting Academic Performance

Author

van der Merwe, D. and de Beer, M.

Abstract

Finding accurate predictors of tertiary academic performance, specifically for disadvantaged students, is essential because of budget constraints and the need of the labour market to address employment equity. Increased retention, throughput and decreased dropout rates are vital. When making admission decisions, the under preparedness of students necessitates that their potential cognitive abilities should be assessed rather than their current abilities. In predicting their academic performance, it is argued that conventional psychometric tests are less suitable for the selection of students from disadvantaged backgrounds, because they are a static measure of current abilities which gives no indication of the student's potential to learn when in an optimum environment. The predictive validity of the Potential Index Battery, the Learning Potential Computerised Adaptive Test and school-leaving results in selection, were determined by calculating the correlation of these measures with academic performance over the full duration of the students' studies. Statistically significant correlations were found, thus indicating that the learning potential test had higher predictive powers than static measures of cognitive ability and school-leaving results, in predicting future academic performance.

Abstract

The NA48/2 experiment at CERN reports the first observation of the K-+/- -> pi(+/-)pi(0)e(+)e(-) decay from an exposure of 1.7 x 10(11) charged kaon decays recorded in 2003-2004. A sample of 4919 candidates with 4.9% background contamination allows the determination of the branching ratio in the full kinematic region, BR(K-+/- -> pi(+/-)pi(0)e(+)e(-)) = (4.24 +/- 0.14) x 10(-6). The study of the kinematic space shows evidence for a structure dependent contribution in agreement with predictions based on chiral perturbation theory. Several P- and CP-violating asymmetries are also evaluated., We gratefully acknowledge the CERN SPS accelerator and beam line staff for the excellent performance of the beam and the technical staff of the participating institutes for their efforts in the maintenance and operation of the detector, and data processing. We thank M. Koval for making the “Prague” radiative Dalitz decay code available in the NA48/2 simulation software. Discussions with G. D'Ambrosio and O. Catà were most stimulating in clarifying the impact of interference terms on our measurement.

44. Embedded entrepreneurs in residential neighbourhoods: dynamics in and effects of social networks

Abstract

This PhD thesis focuses on entrepreneurs and small firms based in residential neighbourhoods in the Netherlands. In the past two decades the neighbourhood has become an increasingly important location for small and home-based firms. Here, working, living and business life are strongly intertwined. This raises the question to what extent firms and entrepreneurs located in residential neighbourhoods make use of and interact with their local environment. In this thesis, the relationship between locally-based entrepreneurs and the neighbourhood context is explored by studying their social networks. Insights from both Economic Geography and Sociology, e.g. Social Network Analysis and Social Capital Theory, are used in this dissertation. The socio-spatial networks of the neighbourhood-based entrepreneurs are studied from a dynamic perspective, allowing for the exploration of network change over time and the effects of these changes on firm performance. Furthermore, this thesis also examines the potential effect of the presence of local entrepreneurship on the neighbourhood context with regard to local social value creation. Literatures on Social Entrepreneurship and Corporate Social Responsibility are used to explore the potential social involvement of these entrepreneurs and the potential drivers of this behaviour. In particular, the role of their (local) social networks is taken into account as explanatory factor. The study has two empirical research parts. The first is a quantitative analysis of the development of the ego-networks of neighbourhood entrepreneurs over a five year period, using data from two waves of a survey (Survey on the Social Networks of Entrepreneurs) conducted in the Netherlands in 2008 and 2014. The second part consists of in-depth interviews with 18 entrepreneurs in two different Dutch cities on their involvement with their local environment and their corresponding local social value creation behaviour. The analyses of the social networks of entrepreneurs located in Dutch residential neighbourhoods, have demonstrated that the social networks of entrepreneurs located in Dutch residential neighbourhoods are important for their firms’ performance change and that their local social networks drives local social value creation. Additionally, this research project has revealed that the social networks of the neighbourhood-based entrepreneurs are far from stable. Through the ability to change their networks over time, the entrepreneurs are found to successfully use their network contacts on behalf of their firms’ development. When turning to the source of the entrepreneurial network contacts, the analyses presented here suggest that Dutch neighbourhood-based entrepreneurs only have a small number of network contacts in the neighbourhoods where they themselves both work and reside. This suggests that the local embeddedness of these firms is limited, making them less locally embedded than was expected at the outset of this study. Thus, although the neighbourhood-based entrepreneurs are socially embedded, their local connections remain limited. This suggests that the role of current-day neighbourhood-based is different from that of the businesses that were present in neighbourhoods between the 1950s and 1980s. This outcome calls for additional research on neighbourhood-based entrepreneurship nowadays and the role it might play on both the economic and social dimensions.

Abstract

NA48/2 results contributing to ChPT testing are presented. A sample of 1663 events of the rare decay $ K^ \pm \to \mu ^ \pm ve^ + e^ - $ has been selected with a minimume+e−effective mass of 140 MeV. The measured model independent decay rate is in agreement with ChPT predictions. The branching ratio of the $ K^ \pm \to \mu ^ \pm ve^ + e^ - $ decay, never observed so far, has been obtained from a sample of about 5000 candidates with less than 6% background, also in agreement with ChPT predictions. In addition, a most precise measurement of the charged kaon semileptonic formfactors has been obtained from 4.4 millionKe3and 2.3 millionKµ3events collected in 2004.

Abstract

Treating mental health care users (MHCUs) with major depressive disorders (MDD) require an inter-professional health team approach that includes occupational therapy. The MHCUs with MDD in psychiatric wards at two private general hospitals followed a standard occupational therapy group programme as part of a treatment plan. The efficacy of this occupational therapy group programme in hospital settings has hardly been previously investigated. This study measured the outcome of a standard occupational therapy group programme on the cognitive, performance and affective functioning components of MHCUs with MDD. The study was conducted in the Occupational Therapy Department at the University of Pretoria. Thirty- five MHCUs with MDD voluntarily participated in nine 90-minute occupational therapy group sessions over a two-week period. A quantitative one group pre-test-post-test study design was employed. The 35 participants were evaluated using The Bay Area Functional Performance Evaluation-Revised (BaFPE-R) prior to and following on a two-week occupational therapy group programme. T-test analysis revealed significant improvements in the pre- to post-testing mean score (p
