Remarks on Fundamental String Cosmology

In recent work, it was shown that velocity-dependent forces between moving strings or branes lead to an accelerating expanding universe without assuming the existence of a cosmological constant. Here we show that the repulsive velocity-dependent force arises in more general contexts and can lead to cosmic structure formation.Comment: 7 pages, harvma

\u27Untitled\u27

When an artist offers a work as \u27untitled\u27, it prevents a certain kind of knowledge; the knowledge given in advance of the effects of the work, and apart from the affects that it gives rise to. The artwork which witholds being known in this a priori way forces instead an interpretation without benefit of the artist\u27s legislation as to its meaning. An interpretation without the force of law. The untitled work, in this way, brings us into the vicinity of the creation of fact and value. It foregrounds the making of understanding, and therefore of knowledge, as an aesthetic event. This paper connects the questions of land, law and art through the double sense of a \u27title\u27; a claim to ownership of land, a claim to know the meaning of the work of art

Ultrastructural Studies of Intercellular Contacts (Junctions) in Bone Marrow. A Review

This paper reviews ultrastructural studies of the intercellular contacts or junctions between cells of the bone marrow. Studies using tannic acid and glutaraldehyde as a fixative have shown pentalaminar complexes between many types of cells in marrow of mice and chicks. These intercellular contacts occur between adjacent stromal cells, between stromal cells and developing blood cells and, in marrow of mice, between migrating blood cells and cells of the sinusoidal wall. Because of their location and widespread occurrence, it is believed these contacts may represent a type of adherent junction helping to maintain an orderly arrangement of blood cells and stromal cells in the marrow. Migrating blood cells may use these contacts as anchoring sites during locomotion toward the sinusoids and in crossing the sinusoidal wall. On the other hand, since these junctions resemble gap junctions of other tissues, one should not exclude the possibility that they are involved in cellular communication. Freeze-fracture and lanthanum impregnation studies have faded to demonstrate these junctions in marrow. Studies using ruthenium red have shown apparent sites of attachment between cells of the marrow, but it is not known whether these sites correspond to the intercellular contacts seen in tannic acid preparations

How performing arts high school students experienced involvement in a Black, student-created and student-led organization focused on uplifting Black art and artists: A critical phenomenological study with implications for culturally responsive and sustaining educational practices

This critical phenomenological study aims to understand the perspectives and experiences of members of Black Arts, a student-created, student-led organization focused on uplifting Black art and artists. The following research question guided this inquiry: What are the experiences of students involved in Black Arts, a student-created, student-led organization focused on uplifting Black art and artists? In addition, three sub-questions were explored: (a) How do students experience their involvement in Black Arts, a student-created, student-led organization focused on uplifting Black art and artists in ways that uplift and magnify their voices and agency? (b) How do student experiences in Black Arts, a student-created, student-led organization focused on uplifting Black art and artists, inform deficit perspectives often held toward Black students and how those deficit perspectives can be disrupted? (c) How do student experiences in Black Arts, a student-created, student-led organization focused on uplifting Black art and artists, inform deficit perspectives often held toward Black art and how those deficit perspectives can be disrupted? Arts-based, Culturally Responsive and Sustaining conceptual framework served as the pedagogical lens for understanding members of the Black Arts organization’s experiences. The data collection methods to gather data from nine participants were semi-structured interviews and Community Learning Exchanges. Data was analyzed with the use of a phenomenological approach of Colaizzi’s (1978), a method for bracketing and analyzing data through a multi-step process. The exploration of this study lobbied for the influence of culturally responsive and sustaining practices at performing and visual arts schools and K-12 schools serving a diverse population of students. The findings provided insight into four main themes: (a) Student perception of school, (b) emancipatory resistance, (c) collective action, and (d) art as transformation. The findings are presented along with implications for K-12 and performing and visual arts schools’ implementation of culturally responsive and sustaining practices

Supporting Career Development and Employment: A Skill Development Practicum

This practicum workbook was designed to aid benefits planners and advocates in supporting the employment decision making process for individuals with disabilities. The first portion of the workbook discusses approaches for understanding interests, preferences, abilities and support needs; impact of choices on financial well-being and independence; supporting the service provider selection process; developing comprehensive work plans; and, quality assurance strategies to evaluate services and supports provided. The workbook concludes with a case application

An Electron Microscopic Study of Microfibrils of Bone Marrow

After fixation of bone marrow with glutaraldehyde, tannic acid and saponin, a delicate network of microfibrils (10 nm) was observed in the extracellular space. Masses of microfibrils were most frequently observed between the endothelial cells of the sinusoidal wall and adventitial reticular cells, but were also observed at other sites throughout the marrow stroma. Microfibrils are an important component of the extracellular material of bone marrow and appear to provide an anchoring substrate for the endothelium

Supporting Career Development and Employment: Benefits Planning, Assistance and Outreach (BPA&O) and Protection and Advocacy for Beneficiaries of Social Security (PABSS)

This training curriculum is dedicated to increasing knowledge and understanding of the Social Security Administration\u27s disability and return to work programs and work incentive provisions as prescribed in the Social Security Act and Ticket to Work and Work Incentives Improvement Act of 1999 as well as other federal benefit programs. These informational resources were compiled and edited to provide continuing education and print materials for benefits specialists and protection and advocacy personnel on the interplay of these benefit programs and impact or employment
