Accuracy Evaluation of the Canadian OpenStreetMap Road Networks

Volunteered geographic information (VGI) has been applied in many fields such as participatory planning, humanitarian relief and crisis management. One of the reasons for popularity of VGI is its cost-effectiveness. However, the coverage and accuracy of VGI cannot be guaranteed. The issue of geospatial data quality in the OpenStreetMap (OSM) project has become a trending research topic because of the large size of the dataset and the multiple channels of data access. This paper provides details on a national study of the Canadian OSM street network data for the assessment ofcompleteness, positional accuracy, attribute accuracy, semantic accuracy and lineage. The findings of the map quality can potentially guide cartographic product selection for interested parties and offer a better understanding of future improvement of OSM quality. In addition, the study presents the complex processes behind OSM contributions possibly influenced by data import and remote mapping

W pogoni za wolnością: przypadki Algernona Sidneya

Celem artykułu jest przypomnienie postaci Algernona Sidneya, angielskiego arystokraty, żołnierza, polityka, rebelianta i myśliciela, żyjącego w XVII w., który przez 40 lat prowadził krucjatę przeciwko absolutystycznym dążeniom Stuartów. Zdaniem autora artykułu, rekonstrukcja dziejów wolności bez uwzględnienia Sidneya byłaby co najmniej niekompletna.Publikacja dofinansowana ze środków przyznanych w ramach dotacji dla Wydziału Prawa i Administracji Uniwersytetu Łódzkiego na rozwój młodych naukowców i doktorantów

On the complexes of historians, and on the new, absolute ignorance, or why and how to teach history in law school

Artykuł jest głosem w dyskusji o roli przedmiotów historyczno-prawnych w programie studiów prawniczych. Autorzy twierdzą, że zmniejszenie popularności i atrakcyjności tych dziedzin jest w dużej mierze efektem niewłaściwego rozumienia celu i formy ich nauczania. Zamiast budować intelektualny etos przyszłych jurystów przyczyniają się one do budowy nowej, absolutnej niewiedzy. Odwołując się do własnej dziedziny naukowej, historii myśli politycznej i prawnej, autorzy szkicują pożyteczny ich zdaniem sposób nauczania.The article is a voice in the debate concerning the role of historical-legal subjects in the curriculum of legal studies. The authors argue that the declining popularity and attractiveness of those subjects largely results from inadequate understanding of the purpose and form of instruction. Instead of building the intellectual ethos of future lawyers they contribute to a new type of absolute ignorance. Referring to their own academic discipline, the history of political and legal thought, the authors outline a workable teaching model

The Edition and Publication of Historical Sources in Poland from the Perspective of Historians of Political and Legal Thought

The article discusses the current state of edition of legal historical sources in Poland from the perspective of historians of political and legal thought. The authors begin by explaining the idea and scope of „source base”specific to their field of research. Three following issues are discussed later: (a) translation of foreign sources into Polish; (b) critical (re)edition of classic Polish texts in political thought; (c) edition of 20th century documental sources by the Institute of National Remembrance and The KARTA Centre. The authors make a number of comments and requests concerning the subject of discussion

Multidifferential study of identified charged hadron distributions in ZZ-tagged jets in proton-proton collisions at s=\sqrt{s}=13 TeV

Jet fragmentation functions are measured for the first time in proton-proton collisions for charged pions, kaons, and protons within jets recoiling against a $Z$ boson. The charged-hadron distributions are studied longitudinally and transversely to the jet direction for jets with transverse momentum 20 $< p_{\textrm{T}} < 100$ GeV and in the pseudorapidity range $2.5 < \eta < 4$. The data sample was collected with the LHCb experiment at a center-of-mass energy of 13 TeV, corresponding to an integrated luminosity of 1.64 fb$^{-1}$. Triple differential distributions as a function of the hadron longitudinal momentum fraction, hadron transverse momentum, and jet transverse momentum are also measured for the first time. This helps constrain transverse-momentum-dependent fragmentation functions. Differences in the shapes and magnitudes of the measured distributions for the different hadron species provide insights into the hadronization process for jets predominantly initiated by light quarks.Comment: All figures and tables, along with machine-readable versions and any supplementary material and additional information, are available at https://cern.ch/lhcbproject/Publications/p/LHCb-PAPER-2022-013.html (LHCb public pages

Study of the B−→Λc+Λˉc−K−B^{-} \to \Lambda_{c}^{+} \bar{\Lambda}_{c}^{-} K^{-} decay

The decay $B^{-} \to \Lambda_{c}^{+} \bar{\Lambda}_{c}^{-} K^{-}$ is studied in proton-proton collisions at a center-of-mass energy of $\sqrt{s}=13$ TeV using data corresponding to an integrated luminosity of 5 $\mathrm{fb}^{-1}$ collected by the LHCb experiment. In the $\Lambda_{c}^+ K^{-}$ system, the $\Xi_{c}(2930)^{0}$ state observed at the BaBar and Belle experiments is resolved into two narrower states, $\Xi_{c}(2923)^{0}$ and $\Xi_{c}(2939)^{0}$, whose masses and widths are measured to be $$m(\Xi_{c}(2923)^{0}) = 2924.5 \pm 0.4 \pm 1.1 \,\mathrm{MeV}, \\ m(\Xi_{c}(2939)^{0}) = 2938.5 \pm 0.9 \pm 2.3 \,\mathrm{MeV}, \\ \Gamma(\Xi_{c}(2923)^{0}) = \phantom{000}4.8 \pm 0.9 \pm 1.5 \,\mathrm{MeV},\\ \Gamma(\Xi_{c}(2939)^{0}) = \phantom{00}11.0 \pm 1.9 \pm 7.5 \,\mathrm{MeV},$$ where the first uncertainties are statistical and the second systematic. The results are consistent with a previous LHCb measurement using a prompt $\Lambda_{c}^{+} K^{-}$ sample. Evidence of a new $\Xi_{c}(2880)^{0}$ state is found with a local significance of $3.8\,\sigma$, whose mass and width are measured to be $2881.8 \pm 3.1 \pm 8.5\,\mathrm{MeV}$ and $12.4 \pm 5.3 \pm 5.8 \,\mathrm{MeV}$, respectively. In addition, evidence of a new decay mode $\Xi_{c}(2790)^{0} \to \Lambda_{c}^{+} K^{-}$ is found with a significance of $3.7\,\sigma$. The relative branching fraction of $B^{-} \to \Lambda_{c}^{+} \bar{\Lambda}_{c}^{-} K^{-}$ with respect to the $B^{-} \to D^{+} D^{-} K^{-}$ decay is measured to be $2.36 \pm 0.11 \pm 0.22 \pm 0.25$, where the first uncertainty is statistical, the second systematic and the third originates from the branching fractions of charm hadron decays.Comment: All figures and tables, along with any supplementary material and additional information, are available at https://cern.ch/lhcbproject/Publications/p/LHCb-PAPER-2022-028.html (LHCb public pages

Measurement of the ratios of branching fractions R(D∗)\mathcal{R}(D^{*}) and R(D0)\mathcal{R}(D^{0})

The ratios of branching fractions $\mathcal{R}(D^{*})\equiv\mathcal{B}(\bar{B}\to D^{*}\tau^{-}\bar{\nu}_{\tau})/\mathcal{B}(\bar{B}\to D^{*}\mu^{-}\bar{\nu}_{\mu})$ and $\mathcal{R}(D^{0})\equiv\mathcal{B}(B^{-}\to D^{0}\tau^{-}\bar{\nu}_{\tau})/\mathcal{B}(B^{-}\to D^{0}\mu^{-}\bar{\nu}_{\mu})$ are measured, assuming isospin symmetry, using a sample of proton-proton collision data corresponding to 3.0 fb${ }^{-1}$ of integrated luminosity recorded by the LHCb experiment during 2011 and 2012. The tau lepton is identified in the decay mode $\tau^{-}\to\mu^{-}\nu_{\tau}\bar{\nu}_{\mu}$. The measured values are $\mathcal{R}(D^{*})=0.281\pm0.018\pm0.024$ and $\mathcal{R}(D^{0})=0.441\pm0.060\pm0.066$, where the first uncertainty is statistical and the second is systematic. The correlation between these measurements is $\rho=-0.43$. Results are consistent with the current average of these quantities and are at a combined 1.9 standard deviations from the predictions based on lepton flavor universality in the Standard Model.Comment: All figures and tables, along with any supplementary material and additional information, are available at https://cern.ch/lhcbproject/Publications/p/LHCb-PAPER-2022-039.html (LHCb public pages
