Judging Judges: Securing Judicial Independence by Use of Judicial Performance Evaluations
This Article discusses judicial performance evaluations as a check on judicial independence. It covers numerous performance evaluation options for measuring accountability, such as bar and media polls, state judicial evaluation programs, and the ABA Guidelines for judicial performance. It discusses the pros and cons of these options. It concludes that the information provided by state judicial performance evaluations offers valuable insight into judicial criticisms and can give voters appropriate criteria to consider in judicial elections
The approach to measuring the returns to secondary and tertiary qualifications in New Zealand : an investigation and update using data from the 2001 census : a research thesis submitted in fulfilment of the requirements for the degree of Master of Applied Economics at Massey University, Department of Applied and International Economics, College of Business, Massey University
This study investigates the approaches to measuring the returns to secondary and tertiary qualifications in New Zealand using the latest Census of Population and Dwellings data from 2001. It calculates the returns to qualifications using income function analysis, elaborate analysis and also extends the elaborate analysis by using the quantile regression technique. It reports returns within a narrow band for both methods and at a similar or higher magnitude to previous years. However, the results reported using the net present value (NPV) criteria reveal higher social returns to qualifications than private returns. This contradicts previous literature. In the policy implications section, the study recommends policies focus more on reducing the level of forgone earnings. Also, the study finds that income function analysis is better suited to measuring income inequality and its link with education. Furthermore, the study concludes that elaborate analysis, using the NPV criteria, allows better comparison of the marginal returns to educational investments of varying scale and duration. Finally, the quantile regression estimates show that point estimates of the mean return give a poor indication of the distribution of returns
Keck spectroscopy of the faint dwarf elliptical galaxy population in the Perseus Cluster core: mixed stellar populations and a flat luminosity function
We present the result of a photometric and Keck-LRIS spectroscopic study of
dwarf galaxies in the core of the Perseus Cluster, down to a magnitude of M_B =
-12.5. Spectra were obtained for twenty-three dwarf-galaxy candidates, from
which we measure radial velocities and stellar population characteristics from
absorption line indices. From radial velocities obtained using these spectra we
confirm twelve systems as cluster members, with the remaining eleven as
non-members. Using these newly confirmed cluster members, we are able to extend
the confirmed colour-magnitude relation for the Perseus Cluster down to M_B =
-12.5. We confirm an increase in the scatter about the colour magnitude
relationship below M_B = -15.5, but reject the hypothesis that very red dwarfs
are cluster members. We measure the faint-end slope of the luminosity function
between M_B = -18 and M_B = -12.5, finding alpha = -1.26 \pm 0.06, which is
similar to that of the field. This implies that an overabundance of dwarf
galaxies does not exist in the core of the Perseus Cluster. By comparing metal
and Balmer absorption line indices with alpha-enhanced single stellar
population models, we derive ages and metallicities for these newly confirmed
cluster members. We find two distinct dwarf elliptical populations: an old,
metal poor population with ages ~ 8 Gyr and metallicities [Fe/H] < -0.33, and a
young, metal rich population with ages
-0.33. Dwarf galaxies in the Perseus Cluster are therefore not a simple
homogeneous population, but rather exhibit a range in age and metallicity.Comment: 12 pages, 9 figures. Accepted for publication in MNRA
