Data visualisation in R
No full textCílem práce je představit možnosti grafického zobrazení dat a ukázat implementaci těchto zobrazení v R. Grafická zobrazení jsou rozdělena dle počtu a charakteru proměnných. Jednotlivá zobrazení jsou popsána a je ukázán postup jejich tvorby. Zobrazení jsou porovnávána mezi sebou a je diskutován jejich přínos stejně tak jako výhody a nevýhody oproti ostatním. Je předvedena jejich implementace v R. Dále je rozvedena tvorba grafů v R obecně, včetně druhotného přizpůsobování a kombinování těchto grafů. Jsou prezentovány autorem vytvořené funkce umožňující tvorbu některých z méně tradičních grafů.The aim of this thesis is to present ways of visualising data using R. Based on the number and types of variables suitable visualisation methods are presented. These methods are described and their creation is explained. They are further discussed and compared. Implementation of these methods in R is shown. Finally, the ways of customizing and combining graphs in R are presented, including some custom author-created functions

Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed

R v Khawaja and the Fraught Question of Rehabilitation in Terrorism Sentencing
No full textIn R v Khawaja, Supreme Court of Canada addressed the question of how courts should handle the sentencing of terrorism offenders. Although it affirmed the Ontario Court of Appeal’s decision to raise the sentence imposed by the trial judge, the Supreme Court took a different approach to the importance of rehabilitation as a goal in terrorism sentencing generally. The Court of Appeal found that because of terrorism’s unique and serious nature, there should be very little consideration of the possibility of rehabilitation. The Supreme Court disagreed, ruling that the weight to be placed on rehabilitation in such cases should be left to trial judges and that, depending on the facts, rehabilitation could be a significant factor even in the context of very serious terror offences.
The author reviews the history of R v Khawaja, contrasting the Supreme Court’s decision with the approach of the Ontario Court of Appeal both in Khawaja and in a number of other cases. He reviews the British and Australian jurisprudence drawn on by the Court of Appeal, which looks on terrorism as a distinct type of crime that calls only for an emphasis on deterrence and punishment in sentencing, and argues that the Supreme Court’s decision indicates a significantly different attitude to the issue. Khawaja allows for rehabilitation to potentially factor into the sentencing of terrorism offenders. The author further considers this decision though the lens Antony Duff’s theory of punishment, which suggests that the concepts of moral agency, equality and the possibility of individual redemption are foundational to a sense of political community. He argues that the Supreme Court’s decision constitutes an implicit affirmation of Duff’s view on the importance of the goal of rehabilitation even for the worst offenders.Peer reviewedPost-prin

A real-time PCR assay to estimate Leishmania chagasi load in its natural sand fly vector Lutzomyia longipalpis
No full textLeishmania chagasi, transmitted mainly by Lutzomyia longipalpis sand flies, causes visceral leishmaniasis and atypical cutaneous leishmaniasis in Latin America. Successful vector control depends upon determining vectorial capacity and understanding Leishmania transmission by sand flies. As microscopic detection of Leishmania in dissected sand fly guts is laborious and time-consuming, highly specific, sensitive, rapid and robust Leishmania PCR assays have attracted epidemiologists' attention. Real-time PCR is faster than qualitative PCR and yields quantitative data amenable to statistical analyses. A highly reproducible Leishmania DNA polymerase gene-based TaqMan real-time PCR assay was adapted to quantify Leishmania in sand flies, showing intra-assay and inter-assay coefficient variations lower than 1 and 1.7%, respectively, and sensitivity to 10 pg Leishmania DNA ( approximately 120 parasites) in as much as 100 ng sand fly DNA. Data obtained for experimentally infected sand flies yielded parasite loads within the range of counts obtained by microscopy for the same sand fly cohort or that were around five times higher than microscopy counts, depending on the method used for data analysis. These results highlight the potential of quantitative PCR for Leishmania transmission studies, and the need to understand factors affecting its sensitivity and specificity
