By Practitioners, For Practitioners: Informing and Empowering Practice Through Practitioner Research

The National Youth-At-Risk Journal was developed to provide meaningful information and resources for professionals who work with youth placed at risk. In order to further this goal, we are calling on practitioners to communicate directly with their colleagues via the journal. We are especially interested in publishing practitioner reports on effective programs, strategies, or interventions that improve both the practice and well-being of youth. The editors provide an overview of practitioner research, describe three approaches to practitioner research, outline the process for conducting practitioner research, and emphasize the role of practitioner-researchers as agents of change. Resources are provided to assist practitioners in conducting research and in reporting their experiences and outcomes

Making the American Dream a Reality for All Youth: Introduction to the First Issue of the \u3ci\u3eNational Youth-At-Risk Journal\u3c/i\u3e

This editorial provides an introduction to the first issue of the National Youth-At-Risk Journal. Information highlighted regarding the journal includes its mission, historical background and inspiration, and holistic aims and scope. Biased and realistic uses of the phrase “at risk” are also addressed. The editorial also introduces the journal editors and presents a preview of issue content

Educating Students in Poverty: Building Equity and Capacity with a Holistic Framework and Community School Model

Educators are often blamed for the achievement gap between low-income and higher income students. We propose to replace the divisive “blame game” with a holistic framework for collaborative action between schools, families, and communities. This 5H Holistic Framework (5HHF) is composed of the 5H protective factors (Health, Hands, Heart, Head, Home). These protective factors holistically address the educational needs and capacities of all students—especially students in poverty—for physical/mental health (Health), safety/security (Hands), social-emotional care (Heart), cognitive development (Head), and family/community support (Home). The 5HHF is used to identify and organize best educational practices and to recommend the community school model to reduce the income-based achievement gap and promote student well-being. The 5HHF of best practices and community school model expands the collective capacity of schools, families, and communities to meet equitably the educational needs of students in poverty and to enhance their opportunities for a quality education. Furthermore, we show how the 5HHF and community school model are aligned with and supported by the Every Student Succeeds Act (ESSA)

The Every Student Succeeds Act (ESSA): What It Means for Educators of Students at Risk

This editorial perspective examines some ways that the Every Student Succeeds Act (ESSA), which becomes operational in the 2017–2018 school year, may enhance the capacity of educators to help students and schools at risk of underperforming. It also addresses some of the challenges that educators will face under ESSA in ensuring success for all students. We highlight aspects of ESSA that may be of most interest to our readers including the broadened definition of academic success, expansion of subgroups for data reporting, emphasis on evidence-based research and practice, focus on continuous improvement, and need for increased educator understanding of research and evaluation. Resources are included that provide information for educators on how to use evidence, locate research findings on existing interventions, and access funding opportunities

The missing GeV {\gamma}-ray binary: Searching for HESS J0632+057 with Fermi-LAT

The very high energy (VHE; >100 GeV) source HESS J0632+057 has been recently confirmed as a \gamma-ray binary, a subclass of the high mass X-ray binary (HMXB) population, through the detection of an orbital period of 321 days. We performed a deep search for the emission of HESS J0632+057 in the GeV energy range using data from the Fermi Large Area Telescope (LAT). The analysis was challenging due to the source being located in close proximity to the bright \gamma-ray pulsar PSR J0633+0632 and lying in a crowded region of the Galactic plane where there is prominent diffuse emission. We formulated a Bayesian block algorithm adapted to work with weighted photon counts, in order to define the off-pulse phases of PSR J0633+0632. A detailed spectral-spatial model of a 5 deg circular region centred on the known location of HESS J0632+057 was generated to accurately model the LAT data. No significant emission from the location of HESS J0632+057 was detected in the 0.1-100 GeV energy range integrating over ~3.5 years of data; with a 95% flux upper limit of F_{0.1-100 GeV} < 3 x 10-8 ph cm-2 s-1. A search for emission over different phases of the orbit also yielded no significant detection. A search for source emission on shorter timescales (days--months) did not yield any significant detections. We also report the results of a search for radio pulsations using the 100-m Green Bank Telescope (GBT). No periodic signals or individual dispersed bursts of a likely astronomical origin were detected. We estimated the flux density limit of < 90/40 \mu Jy at 2/9 GHz. The LAT flux upper limits combined with the detection of HESS J0632+057 in the 136-400 TeV energy band by the MAGIC collaboration imply that the VHE spectrum must turn over at energies <136 GeV placing constraints on any theoretical models invoked to explain the \gamma-ray emission.Comment: 11 pages, 4 figures, accepted for publication in Monthly Notices of the Royal Astronomical Society (MNRAS) Main Journa
