The Employment Retention and Advancement Project: Results from the Substance Abuse Case Management Program in New York City

Participants in an intensive care management program for public assistance recipients with substance abuse problems were slightly more likely to enroll in treatment than participants in less intensive services. However, the intensive program had no effects on employment or public benefit receipt among the full sample

The difference that tenure makes

This paper argues that housing tenures cannot be reduced to either production relations or consumption relations. Instead, they need to be understood as modes of housing distribution, and as having complex and dynamic relations with social classes. Building on a critique of both the productionist and the consumptionist literature, as well as of formalist accounts of the relations between tenure and class, the paper attempts to lay the foundations for a new theory of housing tenure. In order to do this, a new theory of class is articulated, which is then used to throw new light on the nature of class-tenure relations

EFEKTIVITAS MODEL STUDENT TEAMS ACHIEVEMENT DIVISIONS PADA PEMBELAJARAN ELEMEN MESIN DI SMK TAMTAMA KROYA

Penelitian ini bertujuan untuk: (1) mengetahui hasil belajar siswa pada pembelajaran elemen mesin menggunakan metode ceramah, (2) mengetahui hasil belajar siswa pada pembelajaran elemen mesin menggunakan model STAD, (3) mengetahui efektifitas model STAD pada pembelajaran elemen mesin, (4) mengetahui perbedaan hasil belajar kelas eksperimen dan kelas kontrol. Metode yang digunakan dalam penelitian ini merupakan metode penelitian experiment. Dalam pelaksanaannya menggunakan jenis quasi experiment. penelitian dilakukan di SMK Tamtama Kroya Cilacap dengan kelas X Teknik Pemesinan 2 (X TP2) sebagai kelompok eksperimen, kelas X Teknik Pemesinan 1 (X TP1) sebagai kelompok kontrol. Kelas X TP2 sebagai kelompok eksperimen mengalami perlakuan dengan menggunakan metode pembelajaran cooperative learning model STAD dalam kegiatan belajar mengajarnya, sedangkan kelas X TP1 sebagai kelompok kontrol tetap menggunakan metode pembelajaran ceramah dan tanya jawab dalam kegiatan belajar mengajarnya. Hasil dari penelitian ini yaitu: (1) Hasil belajar kelas kontrol yang menggunakan metode ceramah memperoleh mean 72,8, modus 73, median 73, nilai tertinggi 85, dan nilai terendahnya adalah 63, (2) Hasil belajar pada kelas eksperimen yang menggunakan model STAD memperoleh mean 83,1, modus 85, median 85, nilai tertinggi 100, dan nilai terendahnya adalah 70, (3) Pembelajaran model STAD dinilai efektif diterapkan pada pembelajaran elemen mesin, hal tersebut dapat dilihat dari aktivitas keaktifan siswa kelas eksperimen lebih baik dibandingkan kelas kontrol, (4) terdapat perbedaan yang signifikan antara hasil belajar kelas kontrol dengan kelas eksperimen, hal tersebut dapat dilihat dari perbedaan rata-rata pada kelas eksperimen lebih tinggi dari nilai rata-rata kelas pada kelas kontrol. Sehingga dapat dikatakan model pembelajaran STAD lebih efektif dibandingkan dengan metode ceramah

The hardest X-ray source in the ASCA Large Sky Survey: Discovery of a new type 2 Seyfert

We present results of ASCA deep exposure observations of the hardest X-ray source discovered in the ASCA Large Sky Survey (LSS) project, designated as AX J131501+3141. We extract its accurate X-ray spectrum, taking account of the contamination from a nearby soft source (AX J131502+3142), separated only by 1'. AX J131501+3141 exhibits a large absorption of NH = (6 +4 -2)x 10^22 H/cm^2 with a photon index \Gamma = 1.5 +0.7 -0.6. The 2--10 keV flux was about 5 x 10^-13 erg/s/cm^2 and was time variable by a factor of 30% in 0.5 year. From the highly absorbed X-ray spectrum and the time variability, as well as the results of the optical follow-up observations (Akiyama et al. 1998, astro-ph/9801173), we conclude that AX J131501+3141 is a type 2 Seyfert galaxy. Discovery of such a low flux and highly absorbed X-ray source could have a significant impact on the origin of the cosmic X-ray background.Comment: 16 pages, 6 figures, requires AAS Latex macro v4.0, to appear in The Astrophysical Journal, text and figures also available at http://www-cr.scphys.kyoto-u.ac.jp/member/sakano/work/paper/index-e.htm

Radial Velocity Studies of Close Binary Stars.XIII

Radial-velocity measurements and sine-curve fits to the orbital radial velocity variations are presented for ten close binary systems: EG Cep,V1191 Cyg, V1003 Her, BD+7_3142, V357 Peg, V407 Peg, V1123 Tau, V1128 Tau, HH UMa, and PY Vir. While most of the studied eclipsing systems are contact binaries, EG Cep is a detached or a semi-detached double-lined binary and V1003 Her is a close binary of an uncertain type seen at a very low inclination angle. We discovered two previously unknown triple systems, BD+7_3142 and PY Vir, both with late spectral-type (K2V) binaries. Of interest is the low-mass ratio (q = 0.106) close binary V1191 Cyg showing an extremely fast period increase; the system has a very short period for its spectral type and shows a W-type light curve, a feature rather unexpected for such a low mass-ratio system.Comment: Accepted by AJ. 19 pages including 5 figure
