    At the beginning or the program my work was strongly oriented toward the individual objects used in the paintings and lacked any cohesive means or unification. Collage was used as an attempt for unification but more was still needed. It was not until I let go or observed or preconceived images and allowed the image to develop from the free now or washes and lines that I was able to allow the picture to give ideas back to me. The pictures were now growing from themselves and from the ideas suggested to me, without having to force the image prior to starting a painting. After many black and white works in this give and take approach I chose to introduce collage and color back into my work. It was also at this point that the choice of subject matter, prior to starting the painting, reappeared. I was now able to work with subject matter as I had before, but in a new, open, and flowing way

    magnetization processes in permalloy overlays on magnetic bubble devices.

    Using colloid techniques domain structure has been studied in several overlay components used in contemporary bubble devices. In isolated elements the demagnetized state is generally simple, containing a small number of domains. The influence of anisotropy on domain structure is demonstrated. Elements initially respond to applied fields by reversible domain boundary movement but in each case it has been found that partial saturation and hysteresis occur once the applied field exceeds a critical value, H(_s). This causes the formation of remanent states with 'magnetization buckling' similar to that found in larger samples of thin-film permalloy. The relationship between and element geometry and thickness and the formation of buckled states by a rotating field were investigated. Such states may adversely affect the operation of a bubble device. The approach to partial saturation in a simple bar has been modelled on the basis of a curved domain wall and approximate values for the saturation field calculated. The external field profile of the bar has also been obtained. Domain structure in various connected chevron columns (bubble detectors) was also studied. In contrast to isolated elements the initial 'zero-field' state in these components is generally one of saturation. This state can be broken by components of applied field parallel or perpendicular to the column and again magnetization buckling is involved. Magnetoresistance changes related to the buckled state were measured and found to be consistent with the colloid observations. These observations can be used to explain the characteristic magnetoresistance signal of a chevron column in a rotating field

    Terrorism and the Rise of ISIS in Egypt

    Using mostly primary source materials this thesis seeks to understand the evolution of and linkages between different terrorist organization that have operated in Egypt and the Sinai, in particular. Of particular interest was the terrorist group Ansar Bayt al-Maqdis (ABM) which later became an Islamic State in Iraq and al-Sham [Syria] (ISIS) affiliate known as Wilayat Sinai. The thesis then documents the group\u27s operations and shows how it has evolved over the past five years into one of ISIS\u27 most lethal affiliates. ISIS\u27 expansion into Egypt by incorporating ABM into its global terrorist network has increased the threat posed by ISIS to Egypt. Finally, the thesis looks at the risks posed to the Multinational Force and Observers (MFO), civilians, and the potential for ISIS to foment sectarian strife in Egypt by targeting Coptic Christians

    Comparative age and growth of two darters, Percina peltata (Stauffer) and Percina notogramma (Raney and Hubbs), in Virginia

    Two closely related species or darters, Percina peltata and Percina notogramma, occur sympatrically in Virginia. An analysis or the number of scale annuli and standard length measurements on 447 peltata and 195 notogrannna revealed four year classes in both species, with very few individuals surviving to III-year class. Both species had approximately 1:1 sex ratios after the first year, in which males were predominant. The growth of both species was approximately the same after the first year; however peltata, the larger species, apparently gains an advantage during the first year which it never loses. The sexes did not differ significantly in either age or growth

    To Help, Not to Hurt : Justice Thomas\u27s Equality Canon

    Get PDF
    To comprehend Justice Thomas’s views on racial equality requires an understanding of how his life experiences influence his approach to questions of race and the law. Recurring themes in his opinions about racial equality include his belief that racial preferences stigmatize their beneficiaries, his concern that the prevailing notion that racial integration is necessary to black achievement is rooted in a presumption of racial inferiority, his worry that affirmative action efforts provide cover for the failure to address the urgent needs of disadvantaged Americans, and his knowledge that seemingly benign policies can mask illicit motives. Finally, Justice Thomas contends that the a proper understanding of the Equal Protection Clause precludes the use of racial classification in all but the narrowest of circumstances

    Analyses of Suspension, Expulsion, and Incarceration Data Reported Under IDEA 2004

    Disproportionate representation in special education has been an enduring issue, even before P.L. 94-142. Though the main focus of research in the area of disproportionate representation has been on the placement of students from historically marginalized racial and ethnic groups into special education programs, disproportionality has been found in other areas such as the use of exclusionary practices and placement in correctional facilities. As more data regarding students with disabilities are accumulated, it is important to investigate current trends in order to ensure patterns of disproportionate representation are understood and perhaps remedied. This study focused on state level data reported by the states and Washington, D.C. under IDEA 2004. State level data sets involving the suspension/expulsion of students with disabilities and placement of students with disabilities in correctional facilities were analyzed using descriptive statistics, risk ratios, and Chi-square tests. The analysis focused on disability categories and the race/ethnicity categories of students with disabilities. Results from risk ratio analyses indicated students with emotional disturbances and students with disabilities identified as Black or African American were most likely to be suspended/expelled as well as placed in correctional facilities during the school years of 2007 to 2011. Chi-square test results were significant for most groups of students with disabilities and race/ethnicity groups of students with disabilities who were suspended/expelled as well as placed in correctional facilities during the school years of 2007 to 2011

    “[I]n a complex society and an era of pervasive governmental regulation, defining the proper realm for free exercise can be difficult.” Burwell v. Hobby Lobby Stores, Inc., 134 S. Ct. 2751, 2781, 2785 (2014) (Kennedy, J., concurring). The Religious Freedom Restoration Act (“RFRA”)2 addresses that difficulty by harmonizing religious freedom and the interests of third parties. RFRA will not exempt free exercise from a law’s command simply because the law substantially burdens religion—nor will it deny a religious exemption simply because the exemption would affect a third party
