Mass Distribution in Hickson Compact Groups of Galaxies

This study presents the mass distribution for a sample of 18 late-type galaxies in nine Hickson Compact Groups. We used rotation curves from high resolution 2D velocity fields of Fabry-Perot observations and J-band photometry from the 2MASS survey, in order to determine the dark halo and the visible matter distributions. The study compares two halo density profile, an isothermal core-like distribution and a cuspy one. We also compare their visible and dark matter distributions with those of galaxies belonging to cluster and field galaxies coming from two samples: 40 cluster galaxies of Barnes et al (2004) and 35 field galaxies of Spano et al. (2008). The central halo surface density is found to be constant with respect to the total absolute magnitude similar to what is found for the isolated galaxies. This suggests that the halo density is independent to galaxy type and environment. We have found that core-like density profiles fit better the rotation curves than cuspy-like ones. No major differences have been found between field, cluster and compact group galaxies with respect to their dark halo density profiles.Comment: 35 pages, 21 figures.

Perbedaan Efektivitas Group Investigation dengan Problem Based Learning terhadap Kerjasama Siswa Mata Pelajaran IPA Siswa Kelas 5 SD Gugus Joko Tingkir

Penelitian ini bertujuan untuk mengetahui efektivitas model pembelajaran GI dan PBL dalam meningkatkan kerjasama IPA kelas 5 SD Gugus Joko Tingkir Salatiga. Jenis penelitian adalah eksperimen. Subjek pada penelitian ini adalah siswa kelas 5 SD Negeri Tingkir Lor 02 yang berjumlah 31 siswa sebagai kelompok eksperimen dan siswa kelas 5 SD Negeri Tingkir Tengah 02 yang berjumlah 27 siswa sebagai kelompok kontrol. Metode pengumpulan data dengan menggunakan non test berupa angket untuk mengetahui hasil kerjasama siswa. Teknik analisis data dengan analisis deskriptif, uji prasyarat parametrik dan statistik inferensial yang menggunakan bantuan aplikasi SPSS 22 for OS Windows. Berdasarkan hasil uji t diperoleh data dengan signifikansi 0,003 < 0,05 maka H0 ditolak dan Ha diterima, artinya terdapat perbedaan rata-rata hasil kerjasama siswa antara penerapan model pembelajaran GI dan PBL. Perbedaan hasil kerjasama IPA yang signifikan didukung oleh perbedaan rerata dua sampel penelitian, dimana rerata hasil kerjasama pada penerapan model pembelajaran GI sebesar 100,65 sedangkan rerata hasil kerjasama pada penerapan model pembelajaran PBL sebesar 93,81 yang berarti bahwa perlakuan pembelajaran dengan model GI memberikan dampak pada hasil kerjasama yang berbeda dan lebih tinggi daripada model pembelajaran PBL. Hasil penelitian ini dapat disimpulkan bahwa terdapat perbedaan efektivitas hasil kerjasama IPA siswa dengan menggunakan model pembelajaran Group Investigation dan Problem Based Learning SD Gugus Joko Tingkir

Life history, patchy distribution, and patchy taxonomy in a shallow-water invertebrate (Mollusca Polyplacophora: Lepidopleurida)

Things without names are difficult to rationalise, and so species that go without names are difficult to conserve or protect. This is a case study in resolving conflicts in historical taxonomy and ‘real’ species (identifiable and evolutionarily relevant groupings) using an approach including population genetics, natural history, and pragmatism. We report the observation that populations of a shallow-water chiton species from Washington and British Columbia demonstrate extremely high site fidelity and patchy distribution. Their limited dispersal potential and isolation could be explained by a brooding life history. This stands in direct contrast with the supposedly wide distribution of this “species”, Leptochiton rugatus (Carpenter in Pilsbry, 1892) sensu lato, from the Sea of Japan to Baja California. But this lineage has previously been suggested to comprise several cryptic species. Indeed, a haplotype network analysis using 61 individual sequences of the cytochrome oxidase c subunit I gene for L. rugatus s.l. revealed four discrete clusters which correspond to different parts of the geographic range. We infer these to represent four distinct species, at least two of which are likely novel. Leptochiton rugatus sensu stricto is herein reinterpreted as restricted to California and Baja California, and the new name L. cascadiensis sp. nov. is established for the lineage with a distribution in the Cascadia coastal bioregion from the panhandle of Alaska to Oregon. There are minor morphological differences among these species in the L. rugatus species complex, but genetic data or morphological observations alone would not have been sufficient to definitively recognise these groups as species-level lineages. The observation that different species within the complex may have different life history strategies provides important support for interpreting different populations as genuinely separate species.</p

Suzaku Observations of Luminous Quasars: Revealing the Nature of High-Energy Blazar Emission in Quiescent States

We present the results from the Suzaku X-ray observations of five flat-spectrum radio quasars (FSRQs), namely PKS0208-512, Q0827+243, PKS1127-145, PKS1510-089 and 3C 454.3. All these sources were additionally monitored simultaneously or quasi-simultaneously by the Fermi satellite in gamma-rays and the Swift UVOT in the UV and optical bands, respectively. We constructed their broad-band spectra covering the frequency range from 10^14 Hz up to 10^25 Hz, and those reveal the nature of high-energy emission of luminous blazars in their low-activity states. The analyzed X-ray spectra are well fitted by a power-law model with photoelectric absorption. In the case of PKS0208-512, PKS1127-145, and 3C 454.3, the X-ray continuum showed indication of hard-ening at low-energies. Moreover, when compared with the previous X-ray observations, we see a significantly increasing contribution of low-energy photons to the total X-ray fluxes when the sources are getting fainter. The same behavior can be noted in the Suzaku data alone. A likely explanation involves a variable, flat-spectrum component produced via inverse-Compton (IC) emission, plus an additional, possibly steady soft X-ray component prominent when the source gets fainter. This soft X-ray excess is represented either by a steep powerlaw (photon indices Gamma ~ 3 - 5) or a blackbody-type emission with temperatures kT ~ 0.1-0.2 keV. We model the broad-band spectra spectra of the five observed FSRQs using synchrotron self-Compton (SSC) and/or external-Compton radiation (ECR) models. Our modeling suggests that the difference between the low and high-activity states in luminous blazars is due to the different total kinetic power of the jet, most likely related to varying bulk Lorentz factor of the outflow within the blazar emission zone.Comment: 36 pages, 8 figures, 11 tables.

Moral Facts, Possible Moral Worlds and Naturalized Ethics

Given his commitment to the project of naturalizing every normative aspect of philosophy; reducing its a priori content to some sort of empirical enterprise, Quine’s inroad into moral philosophy is expected to set the stage for the project of naturalizing ethics. However, Quine argues that ethics is methodologically infirmed. Hence, the hope of naturalizing ethics hits the rock. This paper aims at advancing the project of naturalizing ethics by an attempt to settle, in a way different from the postulations of Flanagan and White, foremost commentators on Quinean ethics, Quine’s charge of methodological infirmity

Cost Implications of Hospital Unionization: A Behavioral Analysis

The growth of unionization among hospital workers was sharply accelerated by the 1974 amendments to the NLRA covering voluntary hospital workers. With continuing inflationary pressures in the hospital sector, the cost implications of the recent and projected growth of hospital unions is of some concern to policy-makers . This paper presents estimates of union cost impacts based on data from hospitals in the states of Maryland, Massachusetts, New York, and Pennsylvania. Cross-sectional regressions with data for 1975 yield positive union impacts of 3.3 percent on total costs, 4.1 to 5.9 percent on cost per case, and 6.1 percent on cost per day. Re-estimation of the model with data on changes over the 1971 -75 period yields similar results. We also find that the cost impact of unionization varies with the pattern of coverage (being lower for service employees and RN's) and with the extent of cost-based reimbursement. This suggests that future cost impacts of union growth may be moderated as prospective payment systems for hospital s become more widespread.
