    Adolescent pregnancy continues to rise in the western world, as does the poverty in which these young women and their children live. Proposed policies responding to unmarried pregnant or parenting adolescents include The Personal Responsibility Act , The GOP Iradership Welfare Reform Bill\u27, The Real Welfare Reform Act , and The Welfare and Teenage Pregnancy Reduction Act . The purpose of this study is to analyze proposed legislation for welfare reform in the state of Minnesota. This legislation is designed to restructure Aid to Families with Dependent Children guidelines as they relate to pregnant and parenting minors. Results of the analysis indicate that assistance continues to be provided to unmarried adolescent mothers through this legislation when there is compliance with two requirements - the minor mother must live at home with her parent and the Aid to Families with Dependent Children assistance check is delivered directly to the minor parent\u27s parent. This thesis examines these policy requirements in the context of historical and contemporary perceptions of unmarried adolescent mothers. The role and function of social work practice implied in the policy is also discussed

    The effect of plasma-core induced self-guiding on phase matching of high-order harmonic generation in gases

    In this work we numerically study a self-guiding process in which ionization plays a dominant role and analyze its effect on high-order harmonic generation (HHG) in gases. Although this type of self-guiding --- termed as plasma-core induced self-guiding in previous works --- limits the achievable cut-off by regulating the intensity of the laser beam, it provides favorable conditions for phase matching, which is indispensable for high-flux gas high-harmonic sources. To underline the role of self-guiding in efficient HHG, we investigate the time-dependent phase matching conditions in the guided beam and show how the spatio-temporally constant fundamental intensity contributes to the constructive build-up of the harmonic field in a broad photon-energy range up to the provided cut-off.Comment: 14 pages, 7 figure

    In diesem Beitrag wird nach der Bedeutung der Judenvernichtung in den Kategorien des Genozid für einen Historiker gefragt. Um die Komplexität dieser Problematik zu zeigen, werden drei Schwerpunkte erörtert. Ausgangspunkt ist die theoretische Auffassung des Begriffes Völkermord mit besonderer Rücksicht auf die Konzeption Raphael Lemkins. Dann wird ein Problem der Historisierung des Holocaust und Bedeutung dieses Prozesses für die Geschichtsschreibung und kollektives Gedächtnis besprochen. Am Ende wird die kurze Beschreibung das Schicksal des menschlichen Körpers im Konzentrationslager als Herausforderung für eine historische Interpretation dargestellt

    The main aim of the paper is to present the evolution of the German concept of space (Raum). The author focuses chiefly on the Nazi interpretations of space and the linking of geographical notion of space with racist ideology. This connection is demonstrated by means of a description of particular concepts of space, while relying on texts published in the press.The main aim of the paper is to present the evolution of the German concept of space (Raum).

    Influence of As on the formation of mask-edge defects during stressed solid phase epitaxy in patterned Si wafers

    No full text
    The influence of As on the evolution of mask-edge defects during stressed solid phase epitaxy of two-dimensional Si⁺ pre-amorphized regions in patterned Si wafers was examined. Mask-edge defects∼60 nm deep formed at 525 °C for As⁺ implant energies of 7.5–50 keV with peak As concentration of ∼5.0×10²⁰ cm⁻³. Defect formation was attributed to an As-enhanced [110] regrowth rate relative to the [001] regrowth rate creating an amorphous/crystalline interface geometry favorable for defect formation. The similarity of mask-edge defect depths with As⁺ implant energy was attributed to surface retardation of [110] regrowth in shallow implants and enhanced [001] regrowth in deeper implants. Results indicate stress effects on regrowth rates are small compared to dopant effects

    "And Is She A Com-pat-riot?": The Exile of Mina Loy

    Get PDF
    In this paper I question the long-standing tradition which has unambiguously assigned the phrase “American modernist poet” to Mina Loy. Loy’s nomadic biographical narrative and her poetry belie such an ascription to American letters, notwithstanding her status in later life as an American citizen. Analyzing a few of her best-known poems (from the “Pound Era”), and highlighting the cultural critique underlying those poems, I suggest that the space in which Loy wrote and lived is ultimately the unclassifiable space of self-exile. In this paper I argue that the marginalized position that Loy’s poetry has been accorded, even in the American literary canon, may be attributed not only to the experimental nature of her poetry, and her detachment from literary circles, but also to her work of mapping feminist, rather than nationalist poetic boundaries

    Enhanced human centric lighting - Individual automated lighting condition by means of a wearable light dosimeter

    Get PDF
    The aim of this research is to develop a wearable daytime light dosimeter that can be implemented in a lighting solution, to offer individual, automated and optimized lighting conditions. To do so, the dosimeter is orientated towards the standard CIE S 026/E:2018 “CIE System for Metrology of Optical radiation for ipRGC-Influenced Responses to Light”, considering the spectral sensitivities of the different retinal receptors and the impact of the field of view. For optimized lighting conditions, the luminaire’s luminous intensity distribution must be adaptable in spectral power distribution and in direction. If the optimal spectral light incidence distribution for ipRGC-influenced responses to light purposes is known, the required luminous intensity distribution of a luminaire for a certain room geometry with certain room surface reflection values can be calculated. For this purpose, a spectral radiosity algorithm is in development. With a feedback loop between luminaire and dosimeter the light distribution can be continuously adapted as required

    Macroscopic effects in noncollinear high-order harmonic generation.

    We study two-color high-order harmonic generation using an intense driving field and its weak second harmonic, crossed under a small angle in the focus. Employing sum- and difference-frequency generation processes, such a noncollinear scheme can be used to measure and control macroscopic phase matching effects by utilizing a geometrical phase mismatch component, which depends on the noncollinear angle. We further show how spatial phase effects in the generation volume are mapped out into the far field allowing a direct analogy with temporal carrier envelope effects in attosecond pulse generation
