    Pope as media star: a long career full of reinvention

    On the whole, a man who is elected as Pope is well on in years. Some, despite this, have managed to reign for a long time, Leo XIII for instance who came to the throne when he was already seventy in 1878, reigned for twenty five years. Wojtyla was elected when he was only fifty eight, in 1978. In the last century or so, the papacy has become visible worldwide through the mass media. On his accession, Wojtyla was presented as a man's man, a sportsman - according to Professor Eamon Duffy of Cambridge University - as a Bishop with balls. Like other media stars who have stayed the test of time, e.g. Madonna, David Bowie, it seems that he has been able to reinvent his media image to some extent; from the active sportsman to the benevolent grandfather to the ailing figure we see today. He has taken on the aspect of a media star, a world traveller, a spiritual leader, a politician, a mediator and a peace leader. He has been described as the most-photographed person on the planet. This paper will attempt to trace these changes and to ascertain, using Vatican and media sources to discover how much of this continual change is driven by the personality of John Paul himself and how much is a deliberate policy on the part of the Vatican

    Lema\^{i}tre's Hubble relationship

    Edwin Hubble is often credited with discovering the expanding Universe based on spectra taken by him. This statement is incorrect and we feel that it is the responsibility of those who are aware of the historical facts to set the record straight.Comment: 3 page letter, more accurately reflects letter published in Physics Today, August 201

    Climates of Warm Earth-like Planets I: 3-D Model Simulations

    Full text link
    We present a large ensemble of simulations of an Earth-like world with increasing insolation and rotation rate. Unlike previous work utilizing idealized aquaplanet configurations we focus our simulations on modern Earth-like topography. The orbital period is the same as modern Earth, but with zero obliquity and eccentricity. The atmosphere is 1 bar N2_{2}-dominated with CO2_{2}=400 ppmv and CH4_{4}=1 ppmv. The simulations include two types of oceans; one without ocean heat transport (OHT) between grid cells as has been commonly used in the exoplanet literature, while the other is a fully coupled dynamic bathtub type ocean. The dynamical regime transitions that occur as day length increases induce climate feedbacks producing cooler temperatures, first via the reduction of water vapor with increasing rotation period despite decreasing shortwave cooling by clouds, and then via decreasing water vapor and increasing shortwave cloud cooling, except at the highest insolations. Simulations without OHT are more sensitive to insolation changes for fast rotations while slower rotations are relatively insensitive to ocean choice. OHT runs with faster rotations tend to be similar with gyres transporting heat poleward making them warmer than those without OHT. For slower rotations OHT is directed equator-ward and no high latitude gyres are apparent. Uncertainties in cloud parameterization preclude a precise determination of habitability but do not affect robust aspects of exoplanet climate sensitivity. This is the first paper in a series that will investigate aspects of habitability in the simulations presented herein. The datasets from this study are opensource and publicly available.Comment: 27 pages ApJS accepted. Expanded Introduction and several additional figure

    Meningkatkan Hasil Belajar Pendidikan Kewarganegaraan Materi HAM melalui Metode Problem Based Learning Bagi Siswa Kelas VII A SMP PGRI Salawati pada Semester II Tahun Pelajaran 2017/2018

    Mata Pelajaran Pendidikan Kewarganegaraan merupakan mata pelajaran yang memfokuskan pada pembentukan warga negara yang memahami dan mampu melaksanakan hak-hak dan kewajibannya untuk menjadi warga negara yang baik, cerdas, terampil, dan berkarakter seperti yang diamanatkan oleh Pancasila dan UUD 1945. Pelaksanaan pembelajaran problem based learning berlangsung secara alamiah dalam bentuk kegiatan siswa bekerja dan mengalami, menemukan dan mendiskusikan masalah serta mencari pemecahan masalah, bukan transfer pengetahuan dari guru ke siswa. Berdasarkan hasil penelitian dan pembahasan peserta didik yang tuntas pembelajaran, dari prasiklus sebanyak 6 orang (25%) mejadi 15 siswa tuntas pada siklus I (62,5%) dan pada siklus II sebanyak 21 siswa (87,5%), sehingga dapat disimpulkan bahwa penggunaan problem based learning dalam pembelajaran Pendidikan Kewarganegaraan (PKn)  pada materi HAM dapat meningkatkan hasil belajar bagi siswa kelas VII-A SMP PGRI Salawati tahun pelajaran 2017/2018

    Dublin City University at CLEF 2004: experiments with the ImageCLEF St Andrew's collection

    Get PDF
    For the CLEF 2004 ImageCLEF St Andrew's Collection task the Dublin City University group carried out three sets of experiments: standard cross-language information retrieval (CLIR) runs using topic translation via machine translation (MT), combination of this run with image matching results from the VIPER system, and a novel document rescoring approach based on automatic MT evaluation metrics. Our standard MT-based CLIR works well on this task. Encouragingly combination with image matching lists is also observed to produce small positive changes in the retrieval output. However, rescoring using the MT evaluation metrics in their current form significantly reduced retrieval effectiveness

    Viewpoints: A high-performance high-dimensional exploratory data analysis tool

    Full text link
    Scientific data sets continue to increase in both size and complexity. In the past, dedicated graphics systems at supercomputing centers were required to visualize large data sets, but as the price of commodity graphics hardware has dropped and its capability has increased, it is now possible, in principle, to view large complex data sets on a single workstation. To do this in practice, an investigator will need software that is written to take advantage of the relevant graphics hardware. The Viewpoints visualization package described herein is an example of such software. Viewpoints is an interactive tool for exploratory visual analysis of large, high-dimensional (multivariate) data. It leverages the capabilities of modern graphics boards (GPUs) to run on a single workstation or laptop. Viewpoints is minimalist: it attempts to do a small set of useful things very well (or at least very quickly) in comparison with similar packages today. Its basic feature set includes linked scatter plots with brushing, dynamic histograms, normalization and outlier detection/removal. Viewpoints was originally designed for astrophysicists, but it has since been used in a variety of fields that range from astronomy, quantum chemistry, fluid dynamics, machine learning, bioinformatics, and finance to information technology server log mining. In this article, we describe the Viewpoints package and show examples of its usage.Comment: 18 pages, 3 figures, PASP in press, this version corresponds more closely to that to be publishe
