    Putting the pieces back together: a group intervention for sexually exploited adolescent girls

    Domestic minor sex trafficking (DMST) is an emerging problem affecting adolescents, families, and communities throughout the United States. Despite a growing awareness of the problem, information regarding treatment is limited. This paper describes a pilot group intervention created for use with DMST victims, focusing specifically on areas that were critical to the development and life of the group: 1) providing education about DMST, 2) reducing shame and addressing stigma, 3) mutual aid, and 4) managing strong emotions through the development of new coping skills. Process examples are given to illustrate this pilot intervention, and recommendations for research and practice are discussed

    Victim or whore: The similarities and differences between victim’s experiences of domestic violence and sex trafficking

    This research review addresses the similarities and differences between domestic violence and sex trafficking victimization. While there is evidence that domestic violence and sex trafficking often cooccur, there is a large disparity in the understanding and interventions utilized by law enforcement as well as the services available for victims of each crime despite the considerable overlap of victimization. This article explores current research regarding domestic violence and sex trafficking with a focus towards identifying areas of overlap and areas distinct to sex trafficking

    Synthesis, design, and fabrication techniques for reconfigurable microwave and millimeter-wave filters

    As wireless communication becomes increasingly ubiquitous, the need for radio receivers which can dynamically adjust to their operating environment grows more urgent. In order to realize reconfigurable receivers, tunable RF front-end components are needed. This dissertation focuses on the theory, design, and implementation of reconfigurable microwave and millimeter-wave filters for use in such receivers. First, a theoretical framework is developed for absorptive bandstop filters, a new class of bandstop filters which overcomes some of the limitations of traditional tunable bandstop filters caused by the use of lossy tunable resonators. This theory is used in conjunction with silicon-micromachining fabrication technology to realize the first ever tunable bandstop filter at W-Band frequencies, as well as a state-of-the-art Ka-band tunable bandstop filter. The problem of bandwidth variation in tunable filters is then addressed. Widely-tunable filters often suffer from variations in bandwidth, excluding them from many applications which require constant bandwidth. A new method for reducing the bandwidth variation of filters using low-loss evanescent-mode cavity resonators is presented, and this technique is used to realize up to 90% reduction of bandwidth variation in octave-tunable bandstop filters. Lastly, a new differential coupling structure for evanescent-mode cavity resonators is developed, enabling the design of fully-balanced and balanced-to-unbalanced (balun) filters. An octave-tunable 3-pole bandpass balun filter using this coupling structure is presented. The balun filter has excellent amplitude and phase balance, resulting in common-mode rejection of greater than 40 dB across its octave tuning range
