Retelling racialized violence, remaking white innocence: the politics of interlocking oppressions in transgender day of remembrance
No full textTransgender Day of Remembrance has become a significant political event among those resisting violence against gender-variant persons. Commemorated in more than 250 locations worldwide, this day honors individuals who were killed due to anti-transgender hatred or prejudice. However, by focusing on transphobia as the definitive cause of violence, this ritual potentially obscures the ways in which hierarchies of race, class, and sexuality constitute such acts. Taking the Transgender Day of Remembrance/Remembering Our Dead project as a case study for considering the politics of memorialization, as well as tracing the narrative history of the Fred F. C. Martinez murder case in Colorado, the author argues that deracialized accounts of violence produce seemingly innocent White witnesses who can consume these spectacles of domination without confronting their own complicity in such acts. The author suggests that remembrance practices require critical rethinking if we are to confront violence in more effective ways.

The effect of DGE on the attainability of mathematical reasoning for geometry problems among mathematics teacher education students.
No full textDynamic Geometry Environment (DGE) programs appeared in the early 1980s, but they did not begin to be used in education until the beginning of the new millennium. Today, they are widely used in teaching of mathematics. DGE class programs allow to mediate the abstract world of Euclidean geometry to students due to their features such as precision of construction, illustrativeness and the possibility to change the construction dynamically. It is generally accepted that appropriate implementation of DGE software in teaching improves its quality. A related question is what is the benefit of this software if a student uses it in the process of finding a solution to a solution to a mathematical problem. This question represents the general research problem of this thesis. The objects of the research were prospective teachers of mathematics at the Faculty of Education. The following findings were found in the research: 1) The software significantly facilitates the discovery of relevant hypotheses, even those for which their relationship to the solution of a problem is not evident from the assignment of the problem. 2) The software significantly helps in the development of logical justification. (Yet, a significant number of students in the research were unable to complete the proof even with the maximum help the software could provide.) 3) Finding relevant hypotheses using the software tools depends in most cases on students' ability to apply formal mathematical knowledge and to think logically. Facts that can be discovered with software tools by chance, without specific student intent, are likely strongly limited. Research has also dealt with the question of why some students are unable to complete a proof even with the help of software. The thesis contains seven chapters and an appendix. In the first three chapters, the research topic of the thesis is generally described. In chapter four, the research questions are formulated. In the following chapter, a model is presented to categorize the actions of the problem solver in the DGE with respect to the goal he/she pursues. Chapter six presents the research methodology, the data obtained and their interpretation. The results are summarized in the final chapter. The appendix contains two challenging geometric problems author has worked on during his studies and in whose solutions the DGE software played a crucial role
Constructing draggable figures using GeoGebra: The contribution of the DGE for geometric structuring
No full textInternational audienceThis study is a research on teaching practice, developed in the context of an elective course on Dynamic Geometry for prospective kindergarten and elementary school teachers taught by the first author of this paper. We aim to analyse the role of GeoGeobra in the development of geometric reasoning, particularly the way individuals geometrically structure figures. The participants are a class of six future teachers. Data was gathered from the participants' portfolios and classroom observation while working on an exploratory task, which focuses on constructing draggable figures. The results show that this type of activity promotes spatial and geometric structuring, beginning with the perception of elements and relationships that enable the dynamic construction, and moving on to the description of the construction using formal concepts associated to the tools of the DGE

Distribution functions of Poisson random integrals: analysis and computation
No full textWe want to compute the cumulative distribution function of a one-dimensional Poisson stochastic integral ()=∫0()() , where N is a Poisson random measure with control measure n and g is a suitable kernel function. We do so by combining a Kolmogorov–Feller equation with a finite-difference scheme. We provide the rate of convergence of our numerical scheme and illustrate our method on a number of examples. The software used to implement the procedure is available on demand and we demonstrate its use in the paper.This research was partially supported by the NSF grants DMS-0706786, and DGE-0221680.

No full textLcang skya rol pa’i rdo rje’s (1717–1786) Lta mgur, a collection of songs on the correct view, is a short but seminal work that expresses the idea of emptiness and dependent origination. A characteristic feature of the Lta mgur is the frequent usage of metaphors. Throughout the work, the author uses the metaphor of “old mother” (a ma rgan mo) to describe emptiness, and that of “brother” (jo jo) to describe dependent origination; the author himself is described metaphorically as “mad little son” (bu chung smyon pa). The Lta mgur provides a vivid description of the process by which the author recognizes (ngo shes) his missing mother, i.e., emptiness, with the assistance of his brother, i.e., the reasoning of dependent origination.
The Lta mgur was composed in 1767 CE when Lcang skya rol pa’i rdo rje was fifty-one years old and staying at Mt. Wutai (Ri bo rtse lnga). Shortly after that, several commentaries were written by his successors belonging to both Dge lugs pa and non-Dge lugs pa schools, each from different viewpoints. First, Dkon mchog ’jigs med dbang po (1728–1791), one of Lcang skya rol pa’i rdo rje’s disciples, composed a commentary from the viewpoint of Madhyamaka philosophy. Then, another Dge lugs pa scholar, Khri chen bstan pa rab rgyas (1759–1815/16) interpreted the Lta mgur from the perspective of Tantra, and hence was criticized by Dbal mang dkon mchog rgyal mtshan (1764–1853). Furthermore, two commentaries on the Lta mgur were written by Rnying ma pa scholars: Kaḥ thog dge rtse mahāpaṇḍita ’gyur med tshe dbang mchog grub (1761–1829) believed that the idea underlying the Lta mgur was none other than “Great Perfection” (rdzogs chen), while Mi pham ’jam dbyangs rnam rgyal rgya mtsho (1846–1912) analyzed the same text in the context of the non-sectarian movement (ris med).
Thus, it is interesting to observe that, although the author himself belongs to Dge lugs pa, scholars both inside and outside that tradition accept his Lta mgur. The abundant usage of symbolic expressions has allowed the Lta mgur to be interpreted diversely.広島大学比較論理学プロジェクト研究センター研究成果報告書（2016年度

Natronobiforma cellulositropha gen. nov., sp. nov., a novel haloalkaliphilic member of the family Natrialbaceae (class Halobacteria) from hypersaline alkaline lakes
No full textSix strains of extremely halophilic and alkaliphilic euryarchaea were enriched and isolated in pure culture from surface brines and sediments of hypersaline alkaline lakes in various geographical locations with various forms of insoluble cellulose as growth substrate. The cells are mostly flat motile rods with a thin monolayer cell wall while growing on cellobiose. In contrast, the cells growing with cellulose are mostly nonmotile cocci covered with a thick external EPS layer. The isolates, designated AArcel, are obligate aerobic heterotrophs with a narrow substrate spectrum. All strains can use insoluble celluloses, cellobiose, a few soluble glucans and xylan as their carbon and energy source. They are extreme halophiles, growing within the range from 2.5 to 4.8 M total Na+ (optimum at 4 M) and obligate alkaliphiles, with the pH range for growth from 7.5 to 9.9 (optimum at 8.5–9). The core archaeal lipids of strain AArcel5T were dominated by C20–C20 dialkyl glycerol ether (DGE) (i.e. archaeol) and C20–C25 DGE in nearly equal proportion. The 16S rRNA gene analysis indicated that all six isolates belong to a single genomic species mostly related to the genera Saliphagus-Natribaculum-Halovarius. Taking together a substantial phenotypic difference of the new isolates from the closest relatives and the phylogenetic distance, it is concluded that the AArcel group represents a novel genus-level branch within the family Natrialbaceae for which the name Natronobiforma cellulositropha gen. nov., sp. nov. is proposed with AArcel5T as the type strain (JCM 31939T = UNIQEM U972T).doi 10.1016/j.syapm.2018.11.007 contains this corrigendum: 1. The species name “cellulotropha” was corrected to “cellulositropha” in the (SPNA), (SPEP) and TITL lines. 2.
