The Utilization of Ferns as a Model Organism for Studying Natural Polyploidization Concept in Genetics Course
No full text: The Genetics lecture in the Department of Biology, Faculty of Mathematics and Natural Science, Universitas Negeri Malang (FMIPA UM) has its own characteristics distinguishing it from Genetics lecture at the other universities. One of characteristics is there are research projects designed by students utilizing various model organisms. Natural polyploidization is one of the concepts learned through the research project. Fern is used as one of model organisms in the research project. The aim of this study was to describe the utilization of ferns as a model organism in Genetics I course in FMIPA UM. The study was conducted with a qualitative approach. The data were collected from January 2016 to September 2016 by interview, observation, and documentation techniques. The data were analyzed using an interactive model of Miles and Huberman. The validity of data were re-tested using an extension of participation, persistence of observation, and triangulation. The research results showed that through research project activities, the students (1) were able to learn the natural polyploidization concept contextually; (2) easier to understand the natural polyploidization concept; and (3) were trained to be a real researcher. Keywords: fern, genetics course, model organis

The construction of Karen Karnak: The multi-author-function
No full textThis thesis is situated within the comparatively recent developments of Web 2.0 and the emergence of interactive WikiMedia, and explores the mode of authorship within a Read/Write culture compared to that of a Read/Only tradition. The hypothesis of this study is that the role of the audience has become merged with the author, and as such, represents new functions and attributes, distinct from a more conventional concept of authorship, in which the roles of audience and author are more separate. Read/Write and participatory culture, as defined by this study, is focused on collaboration, and includes the influences of D.I.Y. culture, Open-Source practices and the production of text by multiple authors. Multi-authorship presents a re-thinking of several concepts which support the notion of the individual author, since the focus of multi-authorship is not on attribution and ownership of a finished text, but on the continued malleability of a text. Modes of multi-authorship, demonstrated in the use of the pseudonyms Alan Smithee and Karen Eliot, represent declarative authors whose names signify multiple origins, whilst concurrently indicating a distinct body of work. The function of these names form an important context to this study, since primary research involves the construction of an experimental mode of multi-authorship utilising WikiMedia technology and the interaction of thirty nine participants, who are invited to create a body of work under the collective pseudonym Karen Karnak. The data generated by this experiment is analysed using aspects of Michel Foucault's author-function to identify and determine power structures inherent in the WikiMedia context. The interplay of power structures, including concepts such as identity, ownership and the body of work, affect the resulting mode of authorship and contribute to the construction of Karen Karnak, suggesting further areas of research into the emerging multi-author
Book review: women in political theory by Jane Duran
No full textWomen in Political Theory is the first volume to explore the intersections of feminism, politics and philosophy, and to consider the contribution of women philosophers to the field of contemporary political thought, claims its author Jane Duran. With a focus on five central thinkers, Sarah Grimké, Anna Julia Cooper, Jane Addams, Rosa Luxemburg, and Hannah Arendt, Duran hopes to show that each woman was in fact an established political theorist of her time. Katherine Williams recommends this volume to students, scholars and readers with an interest in philosophy, political and social theory, feminism, and gender studies
Paul de Burgos et Profiat Duran déchiffrent 1391
No full textSe fondant sur des textes écrits au moment des pogroms et conversions forcées de 1391, l’auteur se propose de mettre en lumière le sens qu’ont donné à ces événements aussi bien ceux qui se sont convertis, comme Paul de Burgos, que ceux qui ont choisi de rester Juifs, comme Profiat Duran. Cette étude permet également une relecture des persécutions subies par les Juifs à travers l’Europe tout au long du Moyen Âge. En effet, Paul de Burgos comme Profiat Duran cherchent à replacer les événements espagnols de 1391 dans un mouvement historique de longue durée, auquel ils cherchent à donner sens.Basándose en textos escritos en el momento de los pogromos y conversiones forzadas de 1391, el autor se propone evidenciar el sentido que tuvieron dichos acontecimientos tanto para aquellos como Pablo de Burgos que se convirtieron como para aquellos como Profiat Duran que decidieron seguir siendo judíos. Este estudio permite asimismo una relectura de las persecuciones padecidas por los judíos a través de Europa a lo largo de la Edad Media. Efectivamente, Pablo de Burgos, como Profiat Duran, tratan de situar los acontecimientos españoles de 1391 en un movimiento histórico de larga duración al que procuran dar sentido.Based on texts written at the time of the pogroms and forced conversions of 1391, the author intends to shed light on the meaning attributed to these events by both those who chose to convert, such as Paul of Burgos, and those who chose to remain Jews, such as Profiat Duran. This study also enables us to review the persecutions which Jews throughout Europe were subjected to during the Middle Ages. Paul of Burgos and Profiat Duran alike tried to place the Spanish events of 1391 in a long-term historical movement to which they strove to give meaning

Distribution This species is only known from the Edwards Plateau of central Texas, locally known as the Texas Hill Country. It comes in close geographic proximity to D. belfragei and D. minimus, where all three species distributions converge at the edge of the Balcones Escarpment in Bexar County. Analyses of mtDNA data indicate that hybridization occurs in this contact zone, and apparent hybrid D. knisleyi x belfragei individuals have been found in this area. Diagnosis Dromochorus knisleyi is most easily confused with the sister taxa D. belfragei. For differential diagnosis, see D. belfragei species account. Description Medium-sized Dromochorus.

Barry Knisley, one of the leading authorities on North American tiger beetle conservation and ecology. D.P. Duran and R.A. Gwiazdowski are greatly indebted to Barry for his mentorship and friendship. Ecology/natural history Dromochorus knisleyi adults have been found from mid-May to late June, but it is likely that they could be active outside of this window. Dromochorus knisleyi is found in upland juniperoak woodlands in the Edwards Plateau, and does not appear to be strongly associated with riparian areas. The preferred habitat is late succession stands of juniper and, as such, it can be difficult for a collector to easily walk through these areas. Adult beetles are active throughout the day and are present in semiopen grassy areas under the cover of juniper trees. The first author observed dozens of beetles over a span of two days, and all adult activity was restricted to these forested areas. Beetles foraged and mated exclusively near or under juniper boughs. Moreover, even during cloudy periods and late in the afternoon, none were observed moving into more open grassy areas outside of the juniper stands. Moreover, beetles were not present in woodlands dominated by oaks. In mixed juniper–oak woodlands, beetles were found exclusively near junipers. This species may be the most ecologically specialized of all Dromochorus. More observations are needed for this rarely collected species. Many aspects of the biology are currently unknown.Published as part of Duran, Daniel P., Herrmann, David P., Roman, Stephen J., Gwiazdowski, Rodger A., Drummond, Jennifer A., Hood, Glen R. & Egan, Scott P., 2019, Cryptic diversity in the North American Dromochorus tiger beetles (Coleoptera: Carabidae: Cicindelinae): a congruence-based method for species discovery, pp. 250-285 in Zoological Journal of the Linnean Society 186 on pages 271-272, DOI: 10.1093/zoolinnean/zly035, http://zenodo.org/record/308923
Joint scaling analysis of atmospheric velocity and wind power plant production
No full textIn a context of energy transition, wind energy is a source of clean energy with the potential of partially satisfying the growing demand. The main problem of this type of energy, and other types of renewable energy remains the discontinuity of the electric power produced in different scales, inducing large fluctuations also called intermittency. This intermittency of wind energy is inherent to the turbulent nature of wind. Here, we consider the relation between velocity and power output with two wind turbine databases. We focus on joint relations with Fourrier analysis, empirical mode decomposition (EMD), Time-dependent intrinsic correlation (TDIC). We also consider the causality using a new method of analysis of the causality between two time series
