Search for the b¯b decay of the Standard Model Higgs boson in associated (W/Z)H production with the ATLAS detector

A search for the bb¯ decay of the Standard Model Higgs boson is performed with the ATLAS experiment using the full dataset recorded at the LHC in Run 1. The integrated luminosities used are 4.7 and 20.3 fb−1 from pp collisions at s√=7 and 8 TeV, respectively. The processes considered are associated (W/Z)H production, where W → eν/μν, Z → ee/μμ and Z → νν. The observed (expected) deviation from the background-only hypothesis corresponds to a significance of 1.4 (2.6) standard deviations and the ratio of the measured signal yield to the Standard Model expectation is found to be μ = 0.52 ± 0.32 (stat.) ± 0.24 (syst.) for a Higgs boson mass of 125.36 GeV. The analysis procedure is validated by a measurement of the yield of (W/Z)Z production with Z→bb¯ in the same final states as for the Higgs boson search, from which the ratio of the observed signal yield to the Standard Model expectation is found to be 0.74 ± 0.09 (stat.) ± 0.14 (syst.)

The Feasibility of Constructing Profiles of Native Americans from the People of Color Racial Identity Attitude Scale: A Brief Report

One hundred and fifty Lumbee Native American college students participated in an inves-tigation of the feasibility of constructing profiles of Native Americans from the People of Color Racial Identity Attitude Scale (PRIAS; Helms, 1995b). Findings suggest that Helms’s instrument may be feasible for constructing racial identity attitudes of Native Americans

Succeeding In School: The Online Reflections of Native American and Other Minority Students

This phenomenological study of students' online responses to the Succeeding in School program offers rare insight into how Native American and other minority students perceived and experienced their school environment. Students' strategies regarding behavior and attitude changes they would use to improve their success and counseling implications are discussed

The Racial Identity and Cultural Orientation of Lumbee American Indian High School Students

The uncertain and complex lineage of the Lumbee American Indian tribe has made the issue of identity of prime concern. The cultural identification, racial identification, bicultural competence, and perceived school environment for 103 Lumbee Indian high school students were examined in this study. Higher self-ratings on American Indian cultural competence and American Indian cultural identification than on White cultural competence and White cultural identification were found, and t-test comparisons revealed no gender differences on responses to the instruments. Analysis of variance was conducted to assess whether differences in perceived school environment could be attributed to cultural orientation. Rather than appearing assimilated, this generation of Lumbees tends to exhibit J. E. Helms's (1995b) Internalization identity status and an American Indian cultural orientation

Separation-individuation and coping : contributions to freshman college adjustment

This study investigated how college adjustment was influenced by the level of separation-individuation and problem-focused coping strategies of freshmen students. Independent variables included Problem-focused Coping (measured by the Adolescent-Coping Orientation for Problem-focused Experiences), Positive Separation Feelings from parents (measured by the Conflictual Independence subscale of the Psychological Separation Inventory and the Separation-Individuation Test of Adolescence), and Independence from Parents (measured by the Functional, Attitudinal, and Emotional Independence subscales of the Psychological Separation Inventory); the dependent variable was college adjustment (measured by the Student Adaptation to College Questionnaire). College freshmen (n = 87) from a mid-sized southeastern university in the United States completed the scales at the end of their first year

The elementary principal as performer : Erving Goffman's analytical framework applied to the principalship

The purpose of this study was to provide a framework that can be used to provide additional meaning to principal leadership at the elementary school level. The study has focused on principal performances or the ability of a principal to maintain a definition of the situation throughout a presentation. Methodology for the study was based on a qualitative research procedure containing descriptive and interpretative concepts. Additional concepts found in the study included portraiture, artistic research, case study, and sharing one's personal history. Two major works were reviewed in detail: The Presentation of Self in Everyday Life by Erving Goffman and The Creation of Settings and the Future Societies by Seymour Sarason. The ideas of these two authors were integrated into a revised framework that included three phases of a socialization process relating to principal performances: Confronting History and Socialization - Disregarding Reality: Phase I, Confronting Reality: Phase II, and Presenting Reality: Phase III

Behavioral modeling of zinc-oxide, thin-film, field-effect transistors and the design of pixel driver, analog amplifier, and low-noise RF amplifier circuits

Zinc-oxide (ZnO) is of great interest due to transparent properties, high breakdown voltages, and low cost. Behavioral modeling is presented in this dissertation to model ZnO thin-film field-effect transistor (FET) drain current versus gate-source overdrive voltage. Initial findings show that in “strong inversion,” saturation, the drain current equation reveals a quartic-law dependency on gate-source overdrive voltage instead of square-law dependency seen in complementary metal-oxide semiconductor (CMOS) with no mobility reduction effects. This is postulated to result from the ZnO mobility showing a square-law increase with gate-source overdrive voltage. A “strong inversion,” saturation model having ±1.6% deviation from measured data is created in verilog-A to simulate and design circuits. Circuits include a fabricated and measured pixel driver circuit sinking 28 µA of current while only having a gate area of 20 µm2. This ZnO thin-film FET pixel driver is believed to have the highest current density reported at the time of this writing. Also, the first known ZnO thin-film FET analog amplifier is analytically designed for a gain of 3 V/V at 10 kHz while drawing only 8 µA of supply current. Finally, the first known ZnO thin-film FET low-noise RF amplifier is designed, utilizing scattering parameters measured at the Air Force Research Laboratory on a device with minimum channel length of 1.25 µm. This amplifier has a small-signal gain of 12.6 dB at 13.56 MHz, and a current drain of 268.4 mA at a drain voltage of 13 V

The crime drop and the security hypothesis

Major crime drops were experienced in the United States and most other industrialised countries for a decade from the early to mid-1990s. Yet there is little agreement over explanation or lessons for policy. Here it is proposed that change in the quantity and quality of security was a key driver of the crime drop. From evidence relating to vehicle theft in two countries it is concluded that electronic immobilisers and central locking were particularly effective. It is suggested that reduced car theft may have induced drops in other crime including violence. From this platform a broader security hypothesis, linked to routine activity and opportunity theory, is outlined
