Integrative taxonomy and systematics of Allodia Winnertz (Diptera, Mycetophilidae)
No full textThis thesis focuses on the fungus gnat genus Allodia in the dipteran family Mycetophilidae. Allodia has historically gone through several systematic changes, with additions and exclusions of taxa, and the diversity and distribution is poorly understood. Therefore, diversity, distribution, taxonomy and phylogeny of the genus, with its two subgenera Allodia s. str. and Brachycampta, is investigated using morphological and molecular data. Based on molecular analyses of data retrieved from high throughput sequencing, Brachycampta is re-established as a valid genus. Further, the 20 Allodia species occurring in the Holarctic region is revised and reviewed, also using DNA sequence data for the first time. Allodia specimens collected in the Himalayan region (Nepal and Bhutan), and in mountainous areas in south and east Africa is studied, revealing previously unknown diversity. Altogether, a total of 21 species are described as new to science in the four papers included in the thesis

Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe 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

Variations on the Author
Get PDF“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
The female genitalia of Tipulidae, Trichoceridae, Ptychopteridae and Mycetophilidae
No full textThe main objective of the present study is to describe and compare the morphology of the female genitalia within a selected number of species and families of the lower Diptera. The results are presented as two papers with a common introduction. The first paper investigates
the differences at the family level, based on four species representing the three families Tipulidae, Trichoceridae and Ptychopteridae. The second paper focuses on differences between species within one genus in the family Mycetophilidae. Females of four species in the genus Allodia Winnertz, 1863 were selected for this part of the study. The females are associated with already identified males through DNA barcoding. The common introduction gives a short review of the phylogeny of the studied taxa, the outline of female genitalia in lower Diptera and of DNA barcoding as a method for associating sexes
