Integration Defended: Berkeley Unified's Strategy to Maintain School Diversity

Describes a desegregation plan that considers the neighborhood's racial makeup and other diversity measures rather than student race in granting school preference. Examines the plan's legal, policy, and demographic context and lessons for other districts

Measuring power

This paper focuses on dynamics within couples, although the authors recognize that dynamics among extended family members and across generations are of substantial interest. Decisions about resource allocations, control over economic resources, whether and how much one works, are all examined.Households. ,Resource allocation. ,Labor. ,Gender. ,

Process-evaluation of tropospheric humidity simulated by general circulation models using water vapor isotopologues: 1. Comparison between models and observations

The goal of this study is to determine how H_2O and HDO measurements in water vapor can be used to detect and diagnose biases in the representation of processes controlling tropospheric humidity in atmospheric general circulation models (GCMs). We analyze a large number of isotopic data sets (four satellite, sixteen ground-based remote-sensing, five surface in situ and three aircraft data sets) that are sensitive to different altitudes throughout the free troposphere. Despite significant differences between data sets, we identify some observed HDO/H_2O characteristics that are robust across data sets and that can be used to evaluate models. We evaluate the isotopic GCM LMDZ, accounting for the effects of spatiotemporal sampling and instrument sensitivity. We find that LMDZ reproduces the spatial patterns in the lower and mid troposphere remarkably well. However, it underestimates the amplitude of seasonal variations in isotopic composition at all levels in the subtropics and in midlatitudes, and this bias is consistent across all data sets. LMDZ also underestimates the observed meridional isotopic gradient and the contrast between dry and convective tropical regions compared to satellite data sets. Comparison with six other isotope-enabled GCMs from the SWING2 project shows that biases exhibited by LMDZ are common to all models. The SWING2 GCMs show a very large spread in isotopic behavior that is not obviously related to that of humidity, suggesting water vapor isotopic measurements could be used to expose model shortcomings. In a companion paper, the isotopic differences between models are interpreted in terms of biases in the representation of processes controlling humidity

The effects of access to health care on infant mortality in Indonesia

This paper examines the impact of access to health facilities and personnel on infant and child mortality in Indonesia. Demographic and Health Survey data are combined with village-level censuses of infrastructure collected by the Central Bureau of Statistics. Because the village-level data are available from two points in time, it is possible to analyse the effects on mortality risks within the village of changes in access to health care. Factors about villages that might affect both access to health care and mortality risks are held constant. Adding a maternity clinic to a village decreases the odds of infant mortality by almost 15 per cent, in comparison to the risk before the clinic was added. An additional doctor reduces the odds by about 1.7 per cent

Using Macroinvertebrates to Test the Water Quality of Lake Nacogdoches

The target of this assessment was to conduct a water quality test on Lake Nacogdoches in Nacogdoches TX. Lake Nacogdoches is operated by the city of Nacogdoches for municipal water supply and recreation. One of the tests that we ran to determine water quality was a macroinvertebrates test. To do this, we kicked up substrate to expose the organisms burrowed deep in the soil and caught them in a d-frame kick net. We then used our macroinvertebrate key to identify the organism and find the level of biodiversity in the lake. This test is essential because biodiversity affects climate stability, the food web, and the maintenance of the entire ecosystem. Therefore, this test will tell us the overall health of the ecosystem as well. Water quality tests will be used to find any pollutants in the area. Testing at the boat ramps by the dam where the water is taken to the Nacogdoches surface water treatment facility is key to find pollution that could be entering our water. At both the East and Westside park, we collected water samples over three different days and then took the samples to the Environmental Assessment lab for testing. Using a thermometer, Hq40d Probe, spectrophotometer, and colorimeter, we tested the samples for temperature, PH, dissolved oxygen, and nitrite (low range)
