The studies presented in this dissertation examine the academic, psychological, and behavioral adjustment of Chinese parachute kids, under-aged foreign students who live in the United States without ...their parents. Study 1 compares the adjustment of these youth to other Chinese immigrant youth who live with their parents and American-born Chinese adolescents. Despite the stress and challenges associated with the parachute experience, Chinese parachute kids are not more academically or psychologically maladjusted than Chinese immigrant adolescents who live with their parents. They are however, more behaviorally maladjusted in terms of substance use, sexual activity, and group/gang fighting. On the other hand, Chinese parachute kids are not more behaviorally maladjusted than American-born Chinese adolescents in terms of sexual activity or group/gang fighting. Thus, Chinese parachute kids seem to be equipped with some sort of cultural capital that protects them from maladjustment. Study 2 examines the relationship between positive and negative social exchanges and Chinese parachute youth adjustment. It also examines the different role each member of the social network has on parachute youth adjustment. Contrary to the hypothesis, supportive relationships are not necessarily related to well-being and conflictual relationships are not necessarily related to distress. However, each member of the social network does influence parachute kid adjustment differently.

The Rapid Assessment for Developmental Disabilities (RADD) was developed to address the challenges of measuring cognition in individuals with intellectual disabilities (ID). As opposed to individuals ...with ID, commonly used intelligence tests such as the Wechsler Intelligence Scale for Children (WISC) 1, the Wechsler Adult Intelligence Scales (WAIS) 2, and the Stanford-Binet (SB) 3 were designed for use with the general population 4. By design on these measures approximately 95% of the population have IQ scores that fall within two standard deviations (SD) from the mean (scores between 70 and 130; Fig. 12.1). Individuals with ID typically have IQ scores more than two SDs from the mean and they represent less than 2.5% of the total population, forming a statistically rare group. Commonly used intelligence tests were not designed to differentiate between the varying levels of ability among individuals at this lowest end of the intelligence spectrum. The RADD was developed to fill the need for measuring the cognitive abilities of individuals with IQ scores more than two standard deviations below the mean (scores below 70).
The electromagnetic calorimeters of the various magnetic spectrometers in Hall C at Jefferson Lab are presented. For the existing High Momentum Spectrometer (HMS) and Short Orbit Spectrometer (SOS), ...design considerations, relevant construction information, and comparisons of simulated and experimental results are included. The energy resolution of the HMS and SOS calorimeters is better than σ/E∼6%/E and pion/electron (π/e) separation of about 100:1 has been achieved in the energy range of 1–5GeV. Good agreement has been observed between the experimental and simulated energy resolutions, but simulations systematically exceed experimentally determined π− suppression factors by close to a factor of two. For the Super High Momentum Spectrometer (SHMS), presently under construction, details on the design and accompanying GEANT4 simulation efforts are given. The anticipated performance of the new calorimeter is predicted over the full momentum range of the SHMS. Good electron/hadron separation is anticipated by combining the energy deposited in an initial (preshower) calorimeter layer with the total energy deposited in the calorimeter.

Objective
To obtain data concerning a history of infection occurring in the 3 months before recognition of the typical weakness and rash associated with juvenile dermatomyositis (JDM).
Methods
...Parents or caretakers of children within 6 months of JDM diagnosis were interviewed by the registry study nurse concerning their child's symptoms, environment, family background, and illness history. Physician medical records were reviewed, confirming the JDM diagnosis.
Results
Children for which both a parent interview and physician medical records at diagnosis were available (n = 286) were included. Diagnoses were as follows: definite/probable JDM (n = 234, 82%), possible JDM (n = 43, 15%), or rash only (n = 9, 3%). The group was predominantly white (71%) and had a girl:boy ratio of 2:1. Although the mean age at onset was 6.7 years for girls and 7.3 years for boys, 25% of the children were ≤4 years old at disease onset. In the 3 months before onset, 57% of the children had respiratory complaints, 30% had gastrointestinal symptoms, and 63% of children with these symptoms of infection were given antibiotics.
Conclusion
This study provides evidence that JDM affects young children. The symptoms of the typical rash and weakness often follow a history of respiratory or gastrointestinal complaints. These data suggest that the response to an infectious process may be implicated in JDM disease pathogenesis.

We report on the first search for atmospheric and for diffuse astrophysical neutrino-induced showers (cascades) in the IceCube detector using 257 days of data collected in the year 2007-2008 with 22 ...strings active. A total of 14 events with energies above 16 TeV remained after event selections in the diffuse analysis, with an expected total background contribution of \(8.3\pm 3.6\). At 90% confidence we set an upper limit of \(E^2\Phi_{90%CL}<3.6\times10^{-7} GeV \cdot cm^{-2} \cdot s^{-1}\cdot sr^{-1} \) on the diffuse flux of neutrinos of all flavors in the energy range between 24 TeV and 6.6 PeV assuming that \(\Phi \propto E^{-2}\) and that the flavor composition of the \(\nu_e : \nu_\mu : \nu_\tau\) flux is \(1 : 1 : 1\) at the Earth. The atmospheric neutrino analysis was optimized for lower energies. A total of 12 events were observed with energies above 5 TeV. The observed number of events is consistent with the expected background, within the uncertainties.
