Wrestling with Destiny: The Cultural Socialization of Anger and Healing in African American Males
Societyâs negative images of Black males have devastating consequences for their emotional and spiritual health. The PLAAY project (Preventing Long-term Anger and Aggression in Youth) is a multi-component program that seeks to reduce the anger and aggression of Black urban youth with a history of interpersonal conflict. The program components include in-vivo assessment and intervention during athletic movement (basketball play and escapist martial arts), cultural socialization therapy, and parent empowerment groups. In the martial arts and basketball intervention components, the role of movement is essential to understanding how the boys express their confidence and frustration. This article begins with a reflection on the authorâs own emotional and cultural anger towards the limits of Western scholarship and collegiality, examines the theological implications of imaging on Black male mental health, and finally describes the development and procedures of PLAAY. Theological and psychological implications of culturally relevant interventions will be discussed
Final Report for the Success of African American Students (SAAS) in Independent Schools project
The Success of African American Students (SAAS) in Independent Schools was a collaborative, longitudinal, mixed-method research project focused on investigating and understanding the variety of social, emotional, and institutional factors that were thought to influence how Black students navigate the independent school environment. SAAS involved researchers from the University of Pennsylvania (Penn) Graduate School of Education working with faculty and staff from several Philadelphia area independent schools. The SAAS project was supported by five years of funding from the National Institute of Mental Health (NIMH). Finally, SAAS utilized qualitative methods such as focus groups and semi-structured interviews as well as quantitative methods such as questionnaire surveys and behavioral observations
Challenging the orthodoxy: union learning representatives as organic intellectuals
Teacher education and continuing professional development have become a key areas of controversy in England since the period of school sector restructuring following the 1988 Education Reform Act. More recently teacher training and professional development have often been used to promote and reinforce a narrow focus on the governmentâs âstandards agendaâ. However, the emerging discourse of ânew professionalismâ has raised the profile of professional development in schools, and together with union learning representatives, there are opportunities to secure real improvements in teachersâ access to continuing professional development. This paper argues however that union learning representatives must go beyond advocating for better access to professional development and should raise more fundamental questions about the nature of professional development and the education system it serves. Drawing on Gramsciâs notion of the âorganic intellectualâ, the paper argues that union learning representatives have a key role as organisers of ideas â creating spaces in which the ideological dominance of current policy orthodoxy might be challenged
Forward Promise: Disrupting Dehumanization and Affirming the Humanity of BYMOC and Their Villages
Dehumanization is the cause of generations of historical trauma. The cycle begins with negative narratives that label people of colorâparticularly boys and young menâviolent, criminal, and animalistic. To combat the perceived threat, dangerous actions are taken by the majority culture and systems which further dehumanize BYMOC. As a result, BYMOC and their villages often hold harmful internal feelings of unworthiness taught by their oppressors. It is not uncommon for them to engage in various forms of self-harm or to harm others. These destructive external reactions are not explained as normal responses to trauma. Stories of their negative reactions become justification for more negative narratives and the cycle begins agai
Terrestrial organic carbon storage in a British moorland
Accurate estimates for the size of terrestrial organic carbon (C) stores are needed to determine their importance in regulating atmospheric CO2 concentrations. The C stored in vegetation and soil components of a British moorland was evaluated in order to: (i) investigate the importance of these ecosystems for C storage and (ii) test the accuracy of the United Kingdom's terrestrial C inventory. The area of vegetation and soil types was determined using existing digitized maps and a Geographical Information System (GIS). The importance of evaluating C storage using 2D area projections, as opposed to true surface areas, was investigated and found to be largely insignificant. Vegetation C storage was estimated from published results of productivity studies at the site supplemented by field sampling to evaluate soil C storage. Vegetation was found to be much less important for C storage than soil, with peat soils, particularly Blanket bog, containing the greatest amounts of C. Whilst the total amount of C in vegetation was similar to the UK national C inventory's estimate for the same area, the national inventory estimate for soil C was over three times higher than the value derived in the current study. Because the UK's C inventory can be considered relatively accurate compared to many others, the results imply that current estimates for soil C storage, at national and global scales, should be treated with caution
Micro-Environment Causes Reversible Changes in DNA Methylation and mRNA Expression Profiles in Patient-Derived Glioma Stem Cells
In vitro and in vivo models are widely used in cancer research. Characterizing the similarities and differences between a patient\u27s tumor and corresponding in vitro and in vivo models is important for understanding the potential clinical relevance of experimental data generated with these models. Towards this aim, we analyzed the genomic aberrations, DNA methylation and transcriptome profiles of five parental tumors and their matched in vitro isolated glioma stem cell (GSC) lines and xenografts generated from these same GSCs using high-resolution platforms. We observed that the methylation and transcriptome profiles of in vitro GSCs were significantly different from their corresponding xenografts, which were actually more similar to their original parental tumors. This points to the potentially critical role of the brain microenvironment in influencing methylation and transcriptional patterns of GSCs. Consistent with this possibility, ex vivo cultured GSCs isolated from xenografts showed a tendency to return to their initial in vitro states even after a short time in culture, supporting a rapid dynamic adaptation to the in vitro microenvironment. These results show that methylation and transcriptome profiles are highly dependent on the microenvironment and growth in orthotopic sites partially reverse the changes caused by in vitro culturing
Teacher unionism in changing times: is this the real ânew unionismâ?
This article provides a case study of union change in an environment in which radical school restructuring is taking place, and active strategies to weaken and marginalize organized teachers are being pursued by the state. The case study union is the National Union of Teachers in England. The article explores a number of different strategies open to teacher unions, utilizing a framework provided by Turner (2004). Drawing on data collected at a national level, and in three local authority areas, I argue that the National Union of Teachersâ response to the erosion of collective bargaining is best presented as an amalgam of strategies focused on workplace organizing, political campaigning, and coalition building. The data demonstrate considerable congruence between national and local strategies, although local data reveal considerable challenges in implementation and consequently considerable unevenness in local experiences
On the shopfloor: exploring the impact of teacher trade unions on school-based industrial relations
Teachers are highly unionised workers and their trade unions exert an important influence on the shaping and implementation of educational policy. Despite this importance there is relatively little analysis of the impact of teacher trade unions in educational management literature. Very little empirical research has sought to establish the impact of teacher unions at school level. In an era of devolved management and quasi-markets this omission is significant. New personnel issues continue to emerge at school level and this may well generate increased trade union activity at the workplace. This article explores the extent to which devolved management is drawing school-based union representation into a more prominent role. It argues that whilst there can be significant differences between individual schools, increased school autonomy is raising the profile of trade union activity in the workplace, and this needs to be better reflected in educational management research
Prototype finline-coupled TES bolometers for CLOVER
CLOVER is an experiment which aims to detect the signature of gravitational
waves from inflation by measuring the B-mode polarization of the cosmic
microwave background. CLOVER consists of three telescopes operating at 97, 150,
and 220 GHz. The 97-GHz telescope has 160 feedhorns in its focal plane while
the 150 and 220-GHz telescopes have 256 horns each. The horns are arranged in a
hexagonal array and feed a polarimeter which uses finline-coupled TES
bolometers as detectors. To detect the two polarizations the 97-GHz telescope
has 320 detectors while the 150 and 220-GHz telescopes have 512 detectors each.
To achieve the target NEPs (1.5, 2.5, and 4.5x10^-17 W/rtHz) the detectors are
cooled to 100 mK for the 97 and 150-GHz polarimeters and 230 mK for the 220-GHz
polarimeter. Each detector is fabricated as a single chip to ensure a 100%
operational focal plane. The detectors are contained in linear modules made of
copper which form split-block waveguides. The detector modules contain 16 or 20
detectors each for compatibility with the hexagonal arrays of horns in the
telescopes' focal planes. Each detector module contains a time-division SQUID
multiplexer to read out the detectors. Further amplification of the multiplexed
signals is provided by SQUID series arrays. The first prototype detectors for
CLOVER operate with a bath temperature of 230 mK and are used to validate the
detector design as well as the polarimeter technology. We describe the design
of the CLOVER detectors, detector blocks, and readout, and present preliminary
measurements of the prototype detectors performance.Comment: 4 pages, 6 figures; to appear in the Proceedings of the 17th

The Science Case for an Extended Spitzer Mission
Although the final observations of the Spitzer Warm Mission are currently
scheduled for March 2019, it can continue operations through the end of the
decade with no loss of photometric precision. As we will show, there is a
strong science case for extending the current Warm Mission to December 2020.
Spitzer has already made major impacts in the fields of exoplanets (including
microlensing events), characterizing near Earth objects, enhancing our
knowledge of nearby stars and brown dwarfs, understanding the properties and
structure of our Milky Way galaxy, and deep wide-field extragalactic surveys to
study galaxy birth and evolution. By extending Spitzer through 2020, it can
continue to make ground-breaking discoveries in those fields, and provide
crucial support to the NASA flagship missions JWST and WFIRST, as well as the
upcoming TESS mission, and it will complement ground-based observations by LSST
and the new large telescopes of the next decade. This scientific program
addresses NASA's Science Mission Directive's objectives in astrophysics, which
include discovering how the universe works, exploring how it began and evolved,
and searching for life on planets around other stars.Comment: 75 pages. See page 3 for Table of Contents and page 4 for Executive
