Data literacy on the road: Setting up a large-scale data literacy initiative in the DataBuzz project

This paper presents the DataBuzz Project. DataBuzz is a high-tech, mobile educational lab, which is housed in a 13-meter electric bus. Its specific goal is to increase the data literacy of different segments of society in the Brussels region through inclusive and participatory games and workshops. In this paper, we will explore how to carry out practical data literacy initiatives geared to the general public. We discuss the different interactive workshops, which have been specifically developed for DataBuzz. We highlight the background, design choices, and execution of this large-scale data literacy initiative. We describe the factors that need to be taken into account to reach successful execution for such an ambitious project and the actions undertaken to become a long-term, sustainable solution. Throughout the article, we use the Data Literacy Competence Model as an analytical lens to analyse individual projects on data literacy and DataBuzz as an integrated project

Data literacy and education: Introduction and the challenges for our field

Data literacy is a hot topic, which is currently discussed in many different fields from open data initiatives, statistics, computer societies, coding initiatives, and beyond. The resulting literature is inspiring but not always satisfying from the perspective of the media literacy scholarly field. The goals behind data literacy are often instrumental and utilitarian in the function of job-related skills or open data initiatives. We hope that this special issue will contribute to a broader discussion about data literacy. In this introductory essay we provide an overarching introduction, highlighting some of the main themes, questions, issues, and insights addressed in the different articles. We weave in our own insights, reflections, and conclusions as well

Data literacy in the smart city: why Smart cities should be populated by MIL Citizens.

Capitulo 3 - MIL Cities and MIL Citizens: Informed, Engaged, Empowered by Media and Information Literacy (MIL).Smart Cities typify the current and future data-rich environments. In these types of environments, technology and the analysis of vast data facilitate more intelligent choices and actions—largely automated using algorithms and artificial intelligence—related to mobility, security, energy use, culture, markets, etc. (Ballon, van der Graaf, & Walravens, 2017). A discussion on the necessity of data literacy has emerged from debates on datafication, big data, open data, artificial intelligence, and algorithms. The question, however, lies on the relation between media and data literacy. In this contribution, we reflect on aspects of data literacy by examining the literature on smart cities and data in smart cities. We argue that smart cities are not automatically media and information-literate cities. Furthermore, smart cities can only become media and information-literate cities by actively developing an open data context, involving citizens in data projects, empowering civil society participation, and stimulating data literacy in a broad sense

Testing General Relativity with Present and Future Astrophysical Observations

One century after its formulation, Einstein's general relativity has maderemarkable predictions and turned out to be compatible with all experimentaltests. Most of these tests probe the theory in the weak-field regime, and thereare theoretical and experimental reasons to believe that general relativityshould be modified when gravitational fields are strong and spacetime curvatureis large. The best astrophysical laboratories to probe strong-field gravity areblack holes and neutron stars, whether isolated or in binary systems. We reviewthe motivations to consider extensions of general relativity. We present a(necessarily incomplete) catalog of modified theories of gravity for whichstrong-field predictions have been computed and contrasted to Einstein'stheory, and we summarize our current understanding of the structure anddynamics of compact objects in these theories. We discuss current bounds onmodified gravity from binary pulsar and cosmological observations, and wehighlight the potential of future gravitational wave measurements to inform uson the behavior of gravity in the strong-field regime

Libro completoThe UNESCO UNITWIN Cooperation Programme on Media and Information Literacy and Intercultural Dialogue (MILID) is based on an initiative from the United Nations Educational, Scientific and Cultural Organization (UNESCO) and the UN Alliance of Civilizations (UNAOC). This Network was created in line with UNESCO’s mission and objectives, as well as the mandate of UNAOC, to serve as a catalyst and facilitator helping to give impetus to innovative projects aimed at reducing polarization among nations and cultures through mutual partnerships. This UNITWIN Network is composed of universities from different geographical areas: Autonomous University of Barcelona (Spain), University of the West Indies (Jamaica), Cairo University (Egypt), University of Sao Paulo (Brazil), Temple University (USA), Tsinghua University (China), Moulay Ismail University (Morocco), Sidi Mohamed Ben Abdellah University (Morocco), University of Guadalajara (Mexico), Western University (Canada), University of Gothenburg (Sweden), Sorbonne Nouvelle University (France), Punjabi University, Patiala (India), University of the South Pacific (Fiji), University of South Africa (South Africa), Nnamdi Azikiwe University (Nigeria), Ahmadu Bello University (Nigeria), Lagos State University (Nigeria), University of Jors (Nigeria), University of Calabar (Nigeria), Hosei University (Japan), University of Latvia (Latvia), Moscow Pedagogical State University (Russia), Corporación Universitaria Minuto de Dios UNIMINUTO (Colombia), Vytautas Magnus University (Lithuania), MICA (India), University of Campinas (Brazil). The main objectives of the Network are to foster collaboration among member universities, to build capacity in each of the countries in order to empower them to advance media and information literacy and intercultural dialogue, and to promote freedom of speech, freedom of information and the free flow of ideas and knowledge. Specific objectives include acting as an observatory for the role of media and information literacy (MIL) in promoting civic participation, democracy and development as well as enhancing intercultural and cooperative research on MIL. The programme also aims at promoting global actions related to MIL and intercultural dialogue. In such a context, a MILID Yearbook series is an important initiative. This MILID Yearbook is a result of a collaboration between UNESCO UNITWIN Cooperation Programme on Media and Information Literacy and Intercultural Dialogue, The Corporación Universitaria Minuto de Dios - UNIMINUTO (Colombia) and the University of Gothenburg (Sweden)

Measurement of ZZ production in leptonic final states at {\surd}s of 1.96 TeV at CDF

In this paper we present a precise measurement of the total ZZ production cross section in pp collisions at {\surd}s= 1.96 TeV, using data collected with the CDF II detector corresponding to an integrated luminosity of approximately 6 fb-1. The result is obtained by combining separate measurements in the four-charged (lll'l'), and two-charged-lepton and two-neutral-lepton (llvv) decay modes of the Z. The combined measured cross section for pp {\to} ZZ is 1.64^(+0.44)_(-0.38) pb. This is the most precise measurement of the ZZ production cross section in 1.96 TeV pp collisions to date.Comment: submitted to Phys. Rev. Let

Measurement of b hadron lifetimes in exclusive decays containing a J/psi in p-pbar collisions at sqrt(s)=1.96TeV

We report on a measurement of $b$-hadron lifetimes in the fully reconstructed decay modes B^+ -->J/Psi K+, B^0 --> J/Psi K*, B^0 --> J/Psi Ks, and Lambda_b --> J/Psi Lambda using data corresponding to an integrated luminosity of 4.3 ${\rm fb}^{-1}$, collected by the CDF II detector at the Fermilab Tevatron. The measured lifetimes are $\tau$B^+ = $1.639 \pm 0.009 ({\rm stat}) \pm 0.009 {\rm (syst) ~ ps}$, $\tau$B^0 = $1.507 \pm 0.010 ({\rm stat}) \pm 0.008 {\rm (syst) ~ ps}$ and $\tau$Lambda_b = $1.537 \pm 0.045 ({\rm stat}) \pm 0.014 {\rm (syst) ~ ps}$. The lifetime ratios are $\tau$B^+/$\tau$B^0 = $1.088 \pm 0.009 ({\rm stat})\pm 0.004 ({\rm syst})$ and $\tau$Lambda_b/$\tau$B^0 = $1.020 \pm 0.030 ({\rm stat})\pm 0.008 ({\rm syst})$. These are the most precise determinations of these quantities from a single experiment.Comment: revised version. accepted for PRL publicatio

Search for High Mass Resonances Decaying to Muon Pairs in root s=1.96 TeV p(p)over-bar Collisions

We present a search for a new narrow, spin-1, high mass resonance decaying to mu(+)mu(-) + X, using a matrix-element-based likelihood and a simultaneous measurement of the resonance mass and production rate. In data with 4.6 fb(-1) of integrated luminosity collected by the CDF detector in p (p) over bar collisions at root s = 1960 GeV, the most likely signal cross section is consistent with zero at 16% confidence level. We therefore do not observe evidence for a high mass resonance and place limits on models predicting spin-1 resonances, including M > 1071 GeV/c(2) at 95% confidence level for a Z' boson with the same couplings to fermions as the Z boson

Measurement of b Hadron Lifetimes in Exclusive Decays Containing a J/Psi in p(p)over-bar Collisions at root s=1.96 TeV

We report on a measurement of b-hadron lifetimes in the fully reconstructed decay modes B+-> J/psi K+, B-0 -> J/psi K*(892)(0), B-0 -> J/psi K-s(0), and Lambda(0)(b)-> J/psi Lambda(0) using data corresponding to an integrated luminosity of 4.3 fb(-1), collected by the CDF II detector at the Fermilab Tevatron. The measured lifetimes are tau(B+)=[1.639 +/- 0.009(stat)+/- 0.009(syst)]ps, tau(B-0)=[1.507 +/- 0.010(stat)+/- 0.008(syst)]ps, and tau(Lambda(0)(b))=[1.537 +/- 0.045(stat)+/- 0.014(syst)]ps. The lifetime ratios are tau(B+)/tau(B-0)=[1.088 +/- 0.009(stat)+/- 0.004(syst)] and tau(Lambda(0)(b))/tau(B-0)=[1.020 +/- 0.030(stat)+/- 0.008(syst)]. These are the most precise determinations of these quantities from a single experiment
