LGBTI variations in crime reporting: how sexual identity influences decisions to call the cops
No full textResearch shows that people vary in their willingness to report crime to police depending on the type of crime experienced, their gender, age, and their race or ethnicity. Whether or not lesbian, gay, bisexual, transgender, and intersex (LGBTI) and heterosexual people vary in their willingness to report crime to the police is not well understood in the extant literature. In this article, I examine variations in LGBTI respondents' attitudes, subjective norms, and perceived behavioral control on their intentions to report crimes to the police. Drawing on a survey of LGBTI individuals sampled from a Gay Pride community event and online LGBTI community forums (N = 329), I use quantitative statistical methods to examine whether LGBTI people's beliefs in police homophobia are also directly associated with the behavioral intention to report crime. Overall, the results indicate that LGBTI and heterosexual people differ significantly in their intention to report crime to the police, and that a belief in police homophobia strongly influences LGBTI people's intention to underreport crime to the police

Beginning teachers’ mathematical knowledge: What is needed?
No full textOver the past decade there has been growing interest in describing and measuring the kinds of mathematical knowledge needed by teachers. Such efforts are in parallel with the development of national standards for teachers, indicating levels of expectation across the years of teachers’ careers. This presentation provides an opportunity for teacher educators and teachers to consider the nature of mathematical knowledge needed by beginning teachers at all levels of schooling. Discussion will be informed by data from an ALTC funded national project that aims to improve the quality of pre-service teachers’ outcomes in mathematics and by the AAMT Standards framework

Open Source Software Adds to Collaboration, Transparency and Reproducibility in Archaeology
No full textAuthor: Pablo Markin Published Online: 2017-11-30 URL: http://openscience.com/open-source-software-contributes-to-project-collaboration-research-transparency-and-reproducibility-in-archeology/ A recent empirical study by Néhémie Strupler and Toby C. Wilkinson demonstrates that openly accessible digital tools, such as open-source Git and R platforms, can increase the transparency of archaeological fieldwork, while adding methodological rigor to its procedures.

Newton polygons and parabolic inhomogeneous symbols of partial differential equations
No full textWhen transforming PDE problems using Fourier and Laplace transforms, we can find functions that represent the problem, and which can be used to determine properties of the problem. We define such functions as symbols . In general, we define the class of symbols are all functions which are represented by a polynomial of the form , where are -homogeneous functions of on the cones , and and homogeneous functions of on the cone and on the cone respectively. These functions have a certain -order that shows the order of the function relative to a relative weight , and a certain -principal part , which is the part of that causes this -order.For such a symbol, we define its Newton polygon as a certain convex hull of points on , which serves as a geometric description of the order of . We define the weight function to be a positive polynomial with the orders found on the vertices of the Newton polygon . We define a notion of order functions, and show the order function of is .We define a notion of parameter-ellipticity and parabolicity for symbols in based on the Newton polygon , namely N-parameter-ellipticity and N-parabolicity. Using various results from the work of R. Denk and M. Kaip \cite{Denk Kaip} and results I introduced myself, we then prove the equivalence between N-parameter-ellipticity and having non-vanishing -principal parts.Bachelor End ProjectApplied Mathematic
Retinitis Pigmentosa GTPase Regulator (RPGR) protein isoforms in mammalian retina:insights into X-linked Retinitis Pigmentosa and associated ciliopathies
No full textMutations in the cilia-centrosomal protein Retinitis Pigmentosa GTPase Regulator (RPGR) are a frequent cause of retinal degeneration. The RPGR gene undergoes complex alternative splicing and encodes multiple protein isoforms. To elucidate the function of major RPGR isoforms (RPGR 1-19 and RPGR ORF15), we have generated isoform-specific antibodies and examined their expression and localization in the retina. Using sucrose-gradient centrifugation, immunofluorescence and co-immunoprecipitation methods, we show that RPGR isoforms localize to distinct sub-cellular compartments in mammalian photoreceptors and associate with a number of cilia-centrosomal proteins. The RCC1-like domain of RPGR, which is present in all major RPGR isoforms, is sufficient to target it to the cilia and centrosomes in cultured cells. Our findings indicate that multiple isotypes of RPGR may perform overlapping yet somewhat distinct transport-related functions in photoreceptors

Search terms on Scopus were: TITLE-ABS-KEY (mycorrhiza* AND "carbon sequestration") OR (mycorrhiza* AND "13C fatty acids") OR (mycorrhiza* AND 14C) OR (mycorrhiza* AND 13C) OR (mycorrhiza* AND npp) OR (mycorrhiza* AND “carbon stor*”)).
- An .R file with code used to test differences between groups, which links to the database. To run the code create a copy of the database in .csv format.
- A .rtf file links to the Google Earth Engine script created for the spatial analysis of net primary production (NPP) per mycorrhizal type (see Table 1 in the associated publication https://doi.org/10.1016/j.cub.2023.02.027).
