    Women's Descent into Crime

    Get PDF
    Indiana University-Purdue University Indianapolis (IUPUI)The rate of criminal involvement of women has historically been lower than that of men; however, that is changing. Changes in societal norms and progress toward gender equality have broadened the scope of female behaviors, and modified traditional female responsibilities and roles in the home potentially influencing their participation in the crime market. However, the bulk of research on criminal activity is based on the male experience. Thus, less is known about female criminals and their motivations. A closer look at women’s trajectories into crime therefore will likely yield important insights. This study investigates the descent into drugs and crime from the perspective of women who have previously been charged with crimes beyond simple possession of illegal substances. The key interest lies in shedding light on the experiences that set these women on the path to criminal activity. Specifically, this project aims to explore what the women themselves perceive as precursors to their criminal experience. Our findings suggest that female descent into crime may run contrary to many widely held beliefs, such as: that criminal careers begin in adolescence; that women become participants in crime through the influence of significant others; and that criminals come from lower class households

    Inhibition of Return in Visual Search: Disentangling Overlapping Contributions with Event-Related Potentials

    Inhibition of return (IOR) refers to the finding that responses to previously attended locations are slower than those to previously unattended locations. Despite over 30 years of research on IOR, there is still no consensus in the field regarding what the underlying mechanism of this effect is. Although IOR is traditionally studied within spatial cueing paradigms, this effect is thought to reflect a mechanism that facilitates efficient visual search. The following studies explored the hypothesis that multiple processes contribute to the IOR effect in visual search and examined whether these are the same processes that result in IOR in cueing tasks. Both behavioral and electrophysiological measures were used to investigate the response patterns and processes underlying IOR in visual search, and subsequently examine those patterns and processes in cueing-like situations. Chapter 2 explored the spatial distribution of IOR within visual search using the N2pc and P1 ERP components. Chapter 3 investigated how IOR is influenced by attentional manipulations to the visual search task. Chapter 4 used the N2pc, P1, and Pd ERP components to examine the influence of priming and distractor suppression on IOR in visual search, in an effort to link IOR-related findings from the visual search and cueing literatures. Overall, the results demonstrated that IOR observed in cueing studies does not appear to result from the same underlying processes as IOR observed in visual search. This suggests that not only do multiple processes underlie the slowing of responses we refer to as IOR, but also that studies of IOR using cueing tasks may not be informative for understanding the mechanisms of efficient visual search

    Over half of breakpoints in gene pairs involved in cancer-specific recurrent translocations are mapped to human chromosomal fragile sites.

    Gene rearrangements such as chromosomal translocations have been shown to contribute to cancer development. Human chromosomal fragile sites are regions of the genome especially prone to breakage, and have been implicated in various chromosome abnormalities found in cancer. However, there has been no comprehensive and quantitative examination of the location of fragile sites in relation to all chromosomal aberrations

    Microwave Components with MEMS Switches

    Get PDF
    RF MEMS switches with metal-metal contacts are being developed for microwave applications where broadband, high linearity performance is required. These switches provide less than 0.2 dB insertion loss through 40 GHz. This paper describes the integration of these switches into selected microwave components such as reconfigurable antenna elements, tunable filters, switched delay lines, and SPDT switches. Microwave and millimeter wave measured results from these circuits are presented
