Relationship Between Weight-Related Teasing And Levels Of Physical Activity, Piroska Boros Jan 2014

Relationship Between Weight-Related Teasing And Levels Of Physical Activity, Piroska Boros

Dissertations and Theses @ UNI

Weight-related teasing is associated with predictors of physical activity such as self-efficacy and social support. It is possible that more frequent weight-related teasing is directly associated with engagement in physical activity.

The purpose of the study was to examine the relationship between weight-related teasing and engagement in physical activity, body composition and physical activity enjoyment among female college students. This study also investigated the possibility that physical activity enjoyment mediates the relationship between weight-related teasing and physical activity.

Fifty-seven female college students participated in the study. Participants completed the Physical Activity Enjoyment Scale to measure how much they enjoyed participating …


Does Child Code-Switching Demonstrate Communicative Competence?: A Comparison Of Simultaneous And Sequential Bilinguals, Katherine Christoffersen Jan 2014

Does Child Code-Switching Demonstrate Communicative Competence?: A Comparison Of Simultaneous And Sequential Bilinguals, Katherine Christoffersen

Writing and Language Studies Faculty Publications

Over the past four decades, code-switching (CS) has been established as a mark of high linguistic competence among adult simultaneous (2L1) bilinguals, those who acquired two ‘first’ languages before age three. The status of CS among second language (L2) learners, who learned one language after age three, is much less clear; children represent an especially understudied population in this line of inquiry. This study aims to address this research gap and presents a comparison of child 2L1 bilinguals and child L2 learners in kindergarten, first and second grade of a Spanish immersion program. Twelve hours of recorded spontaneous classroom speech …

Dynamical Models Of Elliptical Galaxies – Ii. M87 And Its Globular Clusters, A. Angello, N. Evans, Aaron Romanowsky, J. Brodie Jan 2014

Dynamical Models Of Elliptical Galaxies – Ii. M87 And Its Globular Clusters, A. Angello, N. Evans, Aaron Romanowsky, J. Brodie

Faculty Research, Scholarly, and Creative Activity

We study the Globular Cluster (GC) system of the nearby elliptical galaxy M87 using the newly available dataset with accurate kinematics (Strader et al.2011). We find evidence for three distinct sub-populations of GCs in terms of colours, kinematics and radial profiles. We show that a decomposition into three populations (blue, intermediate and red GCs) is statistically preferred to one with two or four populations, and relate them to the stellar profile. We exploit the sub-populations to derive dynamical constraints on the mass and Dark Matter (DM) content of M87 out to ∼100 kpc. We use a class of global mass-estimators …


The Sluggs Survey: New Evidence For A Tidal Interaction Between The Early Type Galaxies Ngc 4365 And Ngc 4342, C. Blom, D. Forbes, C. Foster, Aaron Romanowsky, J. Brodie Jan 2014

The Sluggs Survey: New Evidence For A Tidal Interaction Between The Early Type Galaxies Ngc 4365 And Ngc 4342, C. Blom, D. Forbes, C. Foster, Aaron Romanowsky, J. Brodie

Faculty Research, Scholarly, and Creative Activity

We present new imaging and spectral data for globular clusters (GCs) around NGC 4365 and NGC 4342. NGC 4342 is a compact, X-ray luminous S0 galaxy with an unusually massive central black hole. NGC 4365 is another atypical galaxy that dominates the W' group of which NGC 4342 is a member. Using imaging from the MegaCam instrument on the Canada-France-Hawaii Telescope (CFHT) we identify a stream of GCs between the two galaxies and extending beyond NGC 4342. The stream of GCs is spatially coincident with a stream/plume of stars previously identified. We find that the photometric colours of the stream …


Ultra Compact Dwarfs In The Core Of The Perseus Cluster: Ucd Formation Via Tidal Stripping, S. Penny, D. Forbes, J. Strader, C. Usher, J. Brodie, Aaron Romanowsky Jan 2014

Ultra Compact Dwarfs In The Core Of The Perseus Cluster: Ucd Formation Via Tidal Stripping, S. Penny, D. Forbes, J. Strader, C. Usher, J. Brodie, Aaron Romanowsky

Faculty Research, Scholarly, and Creative Activity

We present the results of a Keck/DEIMOS survey of Ultra Compact Dwarfs (UCDs) in the Perseus Cluster core. We confirm cluster membership for 14 UCDs, with radial velocities ~5300 km s−1. Two of these confirmed Perseus UCDs have extremely blue colours (B−R<0.6 mag), reside in star forming filaments surrounding NGC 1275, and have likely formed as massive star clusters in the last ~100 Myr. We also measure a central velocity dispersion of a third, UCD13 (σ0=38±8 km s−1), the most extended UCD in our sample. We determine it to have radius Re=85±1.1 pc, a dynamical mass of (2.3±0.8)×108 M⊙, and a metallicity [Z/H]=−0.52+0.33−0.29 dex. UCD13 and the cluster's central galaxy, NGC 1275, have a projected separation of 30 kpc and a radial velocity difference of ~20 km s−1. Based on its size, red colour, internal velocity dispersion, dynamical mass, metallicity and proximity to NGC 1275, we argue that UCD13 is likely the remnant nucleus of a tidally stripped dE, with this progenitor dE having MB≈−16 mag and mass ∼109 M⊙.
