International Bibliography of Carillon Music by Women, Transgender, and Nonbinary Composers

This open-access international bibliography lists published and unpublished original carillon works by over a hundred women, transgender, and nonbinary composers. The composers’ birth years range from 1858 to the twenty-first century, the musical styles range from lyrical to avant-garde, and the formats range from solo to ensemble to electroacoustic. The listings are followed by two appendices. Appendix A lists arrangements and transcriptions, written for carillon, of music by women composed for other instruments or voice. Appendix B comprises an online streaming playlist of music by women carillon composers, with links to free audio and video across the web. We outline our research findings in the introduction, supplemented by charts and tables for ease of visualizing the data we gathered on gender inequity at the national and international carillon conference level

Sexual Orientation, Work Values, Pay, and Preference for Public and Nonprofit Employment: Evidence from Canadian Postsecondary Students

Despite some evidence that gay men hold fewer government jobs in the U.S. than their population share would predict, analysis of two large surveys of Canadian university and college students shows no lack desire for public sector jobs among GLBTQs. Instead, we find that (1) GLBTQs are more likely than heterosexuals to prefer public and nonprofit sector employment; (2) GLBTQ career goals and work values predict a stronger desire for public and nonprofit sector jobs than do those of heterosexuals; and (3) GLBTQs expect to pay a smaller penalty for working in the public and nonprofit sectors. In partial support of public service motivation theory, we find that altruistic motives drive students to both the public and the nonprofit sectors (though desires for job security and strong health and benefit plans have a bigger impact on wanting a government job). Despite economists’ findings that the federal government pays comparable workers more than the private sector, students preparing for government jobs expect to earn less than those heading to the private sector, and students who prioritize starting salary and advancement opportunities prefer private sector jobs

Computably enumerable Turing degrees and the meet property

Working in the Turing degree structure, we show that those degrees which contain computably enumerable sets all satisfy the meet property, i.e. if a is c.e. and b < a, then there exists non-zero m < a with b ^m = 0. In fact, more than this is true: m may always be chosen to be a minimal degree. This settles a conjecture of Cooper and Epstein from the 80s

The E12 experience: Students’ perceptions of a widening participation scheme

Engaging students from lower socioeconomic backgrounds in higher education is an ongoing issue in the tertiary education sector. Despite schemes to widen participation, low SES entry rates remain below 20% in Australia. Various factors have been posited for the low rates of success and strategies aimed at universities, high schools and individual students have been suggested. The literature on transition to university has informed a student-centred approach and the need to acknowledge dimensions of cultural capital. Resources to address difficulties in transition have been suggested. In this paper we report on qualitative research exploring the perspective of students who entered a Faculty of Health Sciences via a widening participation scheme. Our findings indicate that while transition strategies must be in place, the provision of ongoing material resources is also an integral factor in supporting student

CMB E/B decomposition of incomplete sky: a pixel space approach

CMB polarization signal may be decomposed into gradient-like (E) and curl-like (B) mode. We have investigated E/B decomposition in pixel space. We find E/B mixing due to incomplete sky is localized in pixel-space, and negligible in the regions far away from the masked area. By estimating the expected local leakage power, we have diagnosed ambiguous pixels. Our criteria for ambiguous pixels (i.e. r_c) is associated with the tensor-to-scalar ratio of B mode power spectrum, which the leakage power is comparable to. By setting r_c to a lower value, we may reduce leakage level, but reduce sky fraction at the same time. Therefore, we have solved \partial \Delta C_l/\partial r_c=0, and obtained the optimal r_c, which minimizes the estimation uncertainty, given a foreground mask and noise level. We have applied our method to a simulated map blocked by a foreground (diffuse + point source) mask. Our simulation shows leakage power is smaller than primordial (i.e. unlensed) B mode power spectrum of tensor-to-scalar ratio r\sim 10^{-3} at wide range of multipoles (50\lesssim l \lesssim 2000), while allowing us to retain sky fraction ~ 0.48.Comment: v2: the point of the method strengthened, v3: criteria for ambiguous pixels rigorously derived, v4: matched with the accepted version in A&A (minor change), v5: typos correcte

Poly[[aquadi-μ3-malonato-hexaphenyl­ditin(IV)] acetone solvate]

The asymmetric unit of the title polymeric complex, {[Sn2=(C6H5)6(C3H2O4)(H2O)]·C3H6O}n, comprises of two Sn cations, one malonate anion and a non-coordinating acetone solvent mol­ecule. Both crystallographically independent Sn cations are five-coordinated by two O and three C atoms in a distorted trigonal-bipyrimidal geometry. One of the Sn cations is bridged by the malonate units, affording polymeric chains which run along [001]. Weak intra­molecular C—H⋯π inter­actions stabilize the mol­ecular structure. In the crystal structure, adjacent chains are inter­connected by inter­molecular O—H⋯O and C—H⋯O hydrogen bonds into a three-dimensional supra­molecular structure. A weak inter­molecular C—H⋯π inter­action is also observed

Dissection, Culture, and Analysis of Xenopus laevis Embryonic Retinal Tissue

The process by which the anterior region of the neural plate gives rise to the vertebrate retina continues to be a major focus of both clinical and basic research. In addition to the obvious medical relevance for understanding and treating retinal disease, the development of the vertebrate retina continues to serve as an important and elegant model system for understanding neuronal cell type determination and differentiation(1-16). The neural retina consists of six discrete cell types (ganglion, amacrine, horizontal, photoreceptors, bipolar cells, and Muller glial cells) arranged in stereotypical layers, a pattern that is largely conserved among all vertebrates (12,14-18). While studying the retina in the intact developing embryo is clearly required for understanding how this complex organ develops from a protrusion of the forebrain into a layered structure, there are many questions that benefit from employing approaches using primary cell culture of presumptive retinal cells (7,19-23). For example, analyzing cells from tissues removed and dissociated at different stages allows one to discern the state of specification of individual cells at different developmental stages, that is, the fate of the cells in the absence of interactions with neighboring tissues (8,19-22,24-33). Primary cell culture also allows the investigator to treat the culture with specific reagents and analyze the results on a single cell level (5,8,21,24,27-30,33-39). Xenopus laevis, a classic model system for the study of early neural development (19,27,29,31-32,40-42), serves as a particularly suitable system for retinal primary cell culture (10,38,43-45). Presumptive retinal tissue is accessible from the earliest stages of development, immediately following neural induction (25,38,43). In addition, given that each cell in the embryo contains a supply of yolk, retinal cells can be cultured in a very simple defined media consisting of a buffered salt solution, thus removing the confounding effects of incubation or other sera-based products (10,24,44-45). However, the isolation of the retinal tissue from surrounding tissues and the subsequent processing is challenging. Here, we present a method for the dissection and dissociation of retinal cells in Xenopus laevis that will be used to prepare primary cell cultures that will, in turn, be analyzed for calcium activity and gene expression at the resolution of single cells. While the topic presented in this paper is the analysis of spontaneous calcium transients, the technique is broadly applicable to a wide array of research questions and approaches (Figure 1)
