    An evaluation of the Avon Park Youth Academy and Street Smart Program (APYA/SS) program. The evaluation demonstrated that the program has the potential to join the modest but growing list of evidence-based practices in juvenile corrections. However, NCCD evaluators recommended that program modifications and further research may be needed for APYA/SS to fully achieve the status of an evidence-based practice

    We present a Spitzer MIPS study of the decay of debris disk excesses at 24 and 70 μ\mum for 255 stars of types F4 - K2. We have used multiple tests, including consistency between chromospheric and X-ray activity and placement on the HR diagram, to assign accurate stellar ages. Within this spectral type range, at 24 μ\mum, 13.6±2.8%13.6 \pm 2.8 \% of the stars younger than 5 Gyr have excesses at the 3σ\sigma level or more, while none of the older stars do, confirming previous work. At 70 μ\mum, 22.5±3.6%22.5 \pm 3.6\% of the younger stars have excesses at \ge 3 σ\sigma significance, while only 4.72.2+3.74.7^{+3.7}_{-2.2}% of the older stars do. To characterize the far infrared behavior of debris disks more robustly, we double the sample by including stars from the DEBRIS and DUNES surveys. For the F4 - K4 stars in this combined sample, there is only a weak (statistically not significant) trend in the incidence of far infrared excess with spectral type (detected fractions of 21.94.3+4.8%^{+4.8}_{-4.3}\%, late F; 16.53.3+3.9%^{+3.9}_{-3.3}\%, G; and 16.95.0+6.3%^{+6.3}_{-5.0}\%, early K). Taking this spectral type range together, there is a significant decline between 3 and 4.5 Gyr in the incidence of excesses with fractional luminosities just under 10510^{-5}. There is an indication that the timescale for decay of infrared excesses varies roughly inversely with the fractional luminosity. This behavior is consistent with theoretical expectations for passive evolution. However, more excesses are detected around the oldest stars than is expected from passive evolution, suggesting that there is late-phase dynamical activity around these stars.Comment: 46 pages. 7 figures.

    Addendum to "Sufficient conditions for three-particle entanglement and their tests in recent experiments"

    Full text link
    A recent paper [M. Seevinck and J. Uffink, Phys. Rev. A 65, 012107 (2002)] presented a bound for the three-qubit Mermin inequality such that the violation of this bound indicates genuine three-qubit entanglement. We show that this bound can be improved for a specific choice of observables. In particular, if spin observables corresponding to orthogonal directions are measured at the qubits (e.g., X and Y spin coordinates) then the bound is the same as the bound for states with a local hidden variable model. As a consequence, it can straightforwardly be shown that in the experiment described by J.-W. Pan et al. [Nature 403, 515 (2000)] genuine three-qubit entanglement was detected.Comment: Two pages, no figures, revtex4; minor changes before publicatio

    How to Improve Erie County’s Work First Program

    Get PDF
    The major shift to a welfare to work model happened in 1996 with the Personal Responsibility and Work Opportunity Act. This federal law aimed to decrease dependency on public assistance by – among other things – forcing people to work for their assistance. Erie County did not need this Act to focus on work. Erie County Department of Social Services has been enforcing work requirements and operating as a work first county since 1988. In 1994, the County created its Welfare to Work Leadership Council. The goal of the council is to bring the community together to find jobs and training for employable public assistance applicants. The two defining programs in Erie County are Jobs Club for the applicant and Workfare for the recipient

    A survey of Remote Jobs and Communities Program(me) providers: one year in

    Get PDF
    This working paper reports on a survey of provider organisations conducted almost one year into the implementation of Remote Jobs and Communities Program. Abstract On 1 July 2013, a new labour market and community participation program-the Remote Jobs and Communities Program (RJCP)-started operating across remote Australia. It replaced several other programs, most importantly Job Services Australia (JSA) and the Community Development Employment Projects (CDEP) scheme. JSA has in recent years been Australia\u27s principal \u27mainstream\u27 labour market program in which all unemployment payment recipients in Australia who are able to work are expected to participate. CDEP is a much longer-standing program, originally designed to provide some form of paid work to Indigenous people living in remote communities. RJCP was presented by the Gillard Labor government as offering services that would be locally flexible, be delivered in partnership with communities and have a strong focus on getting people into work.  Its dual focus-on community participation and on jobs-was reflected in arrangements for its administration, jointly managed by the Department  of Families, Housing, Community Services and Indigenous Affairs and the Department of Education, Employment and Workplace Relations. However, a change of government in September 2013 brought RJCP into the Department of the Prime Minister and Cabinet. The new Abbott Coalition government was critical of RJCP and immediately included it in a review of Indigenous employment and training programs, led by Andrew Forrest. This working paper reports on a survey of provider organisations conducted almost one year into the implementation of RJCP. It is part of a larger research project on the implementation of RJCP during its first three years, with funding support from the Australian Research Council and Jobs Australia (Linkage Project 130100226). The project aims to understand how RJCP is developed from a general policy idea to specific grounded practice, at the community, regional and jurisdictional levels. This survey report includes findings about basic arrangements and characteristics of provider organisations; ideas about joblessness in remote areas and welfare conditionality; provider perceptions of the government officials with whom they work; operational details (staffing, money and administrative challenges including information technology (IT) systems); and broader influences on the shaping of program delivery, like Community Action Plans and community perceptions. A second survey in 2015–16 will track developments in these areas over time

    BAC\u27s Comeback: The Bricklayers\u27 Renewal Program

    [Excerpt] The Bricklayers\u27 and Allied Craftsmen\u27s International Union (BAC) typifies the contemporary crisis of the building trades. Membership plunged from a high of 160,000 in 1970 to just over 100,000 in 1986. As a result, the International Union ran a budget deficit five years in a row. Fewer than half the craftsmen in BAC\u27s jurisdiction now belong to the union, and many BAC members can be found working on nonunion projects. Even where union contracts prevail, wage and work-rule concessions have become standard fare. But BAC is not taking its decline lying down. Over the past five years, the International Union has embarked on an imaginative process of renewal, one which combines efforts to revive the masonry industry with programs to strengthen the union through education, organizing, and structural reform. While it is too early to tell whether BAC\u27s campaign will succeed, it is already clear that the effort has brought new hope and determination to a union that desperately needed them

    Assessing the impact of “more-flexible” learning as part of a study program

    With the increasing use of Flexible Learning approaches in Higher Education at the Zurich University of Applied Sciences (ZHAW), measuring their effectiveness, from both an educational and a participant's point of view, is of particular importance. In response to the limited scientific contributions on this topic, this article presents a possibility of how an assessment can take place: this study analyzes 62 undergrad-uate student responses to a Blended Learning task and compares the participant findings with a pre-existing educational competency framework

    Persistence in Mathematics by Underrepresented Students: Experiences of a Math Excel Program

    Get PDF
    Success in mathematics by underrepresented and nontraditional college students is measured not only by academic performance (grades), but also by the continued participation and persistence of these students in mathematics coursework. The Math Excel program at Oregon State University attempts to build learning communities with a sharp academic focus in support of students concurrently taking introductory level mathematics courses. The Math Excel program is based heavily on Uri Treisman\u27s Emerging Scholars Workshop model of collaborative problem solving. In this article, we examine the experience of minority students in the Educational Opportunities Program participating in the Math Excel program. While the program had appeared successful in terms of improving academic performance in the concurrent mathematics course, the continued participation and persistence of these students in mathematics was disappointing. On a trial basis, structural changes were made to build a much stronger identification of the Math Excel learning community with a section of College Algebra. In the next term, there was a much higher incidence of participation in the subsequent Precalculus using the same Math Excel structure. While the collaborative problem solving activity provided in Math Excel was crucial to students\u27 successful academic performance, these results suggest that subtle issues related to students\u27 recognition of and identification with a learning community may be critically important to underrepresented and nontraditional students\u27 continued persistence in mathematics
