    Full text link
    A first measurement of the top quark spin asymmetry, sensitive to the top quark polarisation, in tt-channel single top quark production is presented. It is based on a sample of pp collisions at a centre-of-mass energy of 8 TeV corresponding to an integrated luminosity of 19.7 fb−1\mathrm{fb^{-1}}. A high-purity sample of tt-channel single top quark events with an isolated muon is selected. Signal and background components are estimated using a fit to data. A differential cross section measurement, corrected for detector effects, of an angular observable sensitive to the top quark polarisation is performed. The differential distribution is used to extract a top quark spin asymmetry of 0.26±0.03(stat)±0.10(syst)0.26 \pm 0.03 \textrm{(stat)} \pm 0.10 \textrm{(syst)}, which is compatible with a p-value of 4.6%4.6\% with the standard model prediction of 0.44.Comment: presented at 9th International Workshop on Top Quark Physics Olomouc, Czech Republic, September 19ñ€“23, 201

    Despite the richness of African proverbs, they have been muted in information systems (IS) research. This explicitly contributes to the lag in developing information systems and technology solutions for African people by African researchers in African terms. It is on this basis that two related objectives were formulated: (1) to examine the role which African proverbs can play in further advancing IS research, and (2) to understand how the concept can be employed to indigenize IS research. Qualitative data were collected from different sources, and the dimension of social change from structuration theory was employed to examine the role African proverbs can significantly play in advancing IS research. The analysis reveals that African proverbs can be employed in all stages of IS research, from problematizing the phenomenon, data collection to data analysis and interpretation of findings

    Human Interaction with Structure in the Computing Environment

    IT strategy is often intended to be driven by the organisational vision and strategy to achieve its goals periodically. IT has significant impact on an organisation’s success or failure. It therefore does not operate in a vacuum. The issue is not just about information technology. Rather, it is the strategic application of technology, including management, which is about people and the process. This research applied Structuration Theory to examine the types of structures that exist during the development and implementation of IT strategy, and the structures that actually emerge as a result of human action in the computing environment of the organisation and through that, identify its impact and how they derail IT strategy in the organisation

    Judul penelitian ini berjudul “Penerapan Model Pembelajaran Cooperative Learning Teknik Listening Team Terhadap Kemampuan Berpikir Kreatif Siswa (Quasi Eksperimen Pada Mata Pelajaran Ekonomi Kelas X Di Sma Negeri 16 Bandung Tahun Pelajaran 2016-2017). Permasalahan dalam penelitian ini yaitu rendahnya kemampuan berfikir kreatif siswa pada mata pelajaran ekonomi. Hal ini dipengaruhi oleh beberapa faktor internal salah satunya yaitu penggunaan model pembelajaran yang monoton. Tujuan dari penelitian ini yait untuk mengetahui penerapan model pembelajaran dalam meningkatkan kemampuan berfikir kreatif siswa pada mata pelajaran ekonomi sub tema koperasi kelas X di SMA Negeri 16 Bandung. Metode yang digunakan dalam penelitian ini yaitu quasi eksperimen dengan menggunakan soal pre test dan post test sebagai alat pengumpulan data. Subjek dalam penelitian ini adalah siswa kelas X IIS 1 dan X MIA 5 di SMA Negeri 16 Bandung yang berjumlah 60 siswa. hasil penelitian terdapat peningkatan hasil belajar siswa antara kelas eksperimen yang menggunakan model pembelajaran listening team dengan kelas kontrol yang menggunakan metode pembelajaran konvensional. Hal ini dibuktikan dari selisih hasil pretest dan posttest, pada kelas eksperimen dengan peningkatan nilai rata-rata sebesar 42,3, sedangkan kelas kontrol sengan peningkatan nilai rata-rata sebesar 9,3. Untuk hasil pengujian uji hipotesis dapat dibuktikan dengan nilai rata-rata N-Gain pada kelas eksperimen sebesar 0,79 dengan interpretasi tinggi, sedangkan kelas kontrol sebesar 0,17 dengan interpretasi rendah, nilai kelas eksperimen lebih tinggi dibandingkan dengan nilai kelas kontrol. Maka dapat disimpulkan bahwa terdapat perbedaan peningkatan hasil belajar siswa pada kelas yang menggunakan model pembelajaran listening team (kelas eksperimen) dengan kelas yang menggunakan model pembelajaran konvensional (kelas kontrol) karena kelas eksperimen mencapai peningkatan hasil belajar yang lebih besar daripada kelas kontrol. Hal ini dibuktikan dari selisih hasil pretest dan posttest, pada kelas eksperimen mencapai peningkatan nilai rata-rata sebesar 42,3 yaitu naik dari hasil pretest 46,87 menjadi 89,17 pada saat posttest, sedangkan kelas kontrol dengan peningkatan nilai rata-rata sebesar 9,3 yaitu naik dari hasil pretest 45,60 menjadi 54,90 pada saat posttest. Sebagai akhir penelitian, penulis menyampaikan saran, siswa diharapkan aktif dalam mengikuti pembelajaran, guru sebaiknya menggunakan berbagai metode pembelajaran agar proses belajar mengajar tidak terlihat pasif dan kepala sekolah menekankan kepada guru untuk men ggunakan metode pembelajaran aktif, serta bagi dinas pendidikan untuk meningkatkan MGMP tingkat sekolah dan meningkatkan standar kompetensi guru lalu untuk penelitian selanjutnya diharapkan menggunakan penelitian serupa dengan menggunakan metode pembelajaran yang berbeda dan kelas yang berbeda pula.

    Get PDF
    This study was undertaken to develop a framework that can be used to guide analysis when translating and transforming big data into a more purposeful resource for healthcare service delivery in South Africa. It is intended to assist in addressing some of the challenges encountered by healthcare facilities. Qualitative data were collected, with a focus on the types of interactions that happen between actors when accessing and using patients’ big data for healthcare services. Actor-network theory (ANT) was applied as a lens in the analysis of the data, to examine the relationships between actors when accessing and using big data for healthcare services. From the analysis, factors influencing the accessing and use of patient’s big data were found. These factors provided the basis from which a framework was developed. The framework can be used to guide the assessment of big data and improve healthcare and service delivery to the community

    Get PDF
    Selection of appropriate big data analytics (BDA) tools (software) for business purposes is increasingly challenging, which sometimes lead to incompatibility with existing technologies. This becomes prohibitive in attempts to execute some functions or activities in an environment. The objective of this study was to propose a model, which can be used to guide the selection of BDA in an organization. The interpretivist approach was employed. Qualitative data was collected and analyzed using the hermeneutics approach. The analysis focused on examining and gaining better understanding of the strengths and weaknesses of the most common BDA tools. The technical and non-technical factors that influence the selection of BDA were identified. Based on which a solution is proposed in the form of a model. The model is intended to guide selection of most appropriate BDA tools in an organization. The model is intended to increase BDA usefulness towards improving organization’s competitiveness
