Children Exposed To Intimate Partner Violence: Exploring Factors That Promote Resiliency., Kimberly P. Foley Jan 2007

Children Exposed To Intimate Partner Violence: Exploring Factors That Promote Resiliency., Kimberly P. Foley

Graduate Theses, Dissertations, and Problem Reports (ETD)

An estimated 3.3 (Carlson, 1984) to 10 million (Straus, 1992) children are exposed to intimate partner violence per year. Exposure to IPV has been shown to have a profound impact upon children’s cognitive, behavioral, and emotional functioning. Until recently, the majority of research examining children’s experiences of IPV approached the field from a deficits perspective; choosing to examine the negative impacts IPV had upon children. This study instead explored the effects of IPV upon children from a resiliency perspective; choosing to examine the adaptive functioning children displayed despite experiencing this trauma. This study explored previously identified constructs such as maternal …

Mapping The Gods: A Geographic Analysis Of The Effects Of The Shrine Merger Policy On Japanese Sacred Space., Christopher M. Todd Jan 2007

Mapping The Gods: A Geographic Analysis Of The Effects Of The Shrine Merger Policy On Japanese Sacred Space., Christopher M. Todd

Graduate Theses, Dissertations, and Problem Reports (ETD)

Sacred space is a critical cultural construction of all religions. It is within this space that people are able to commune with deities and step out of the common, profane world. Japanese Shinto sacred space has undergone many changes throughout its history. One of the largest alterations was the introduction of the Shrine Merger Policy in 1906. Across the nation, thousands of shrines were demolished and merged under governmental authorization. The goal of this study is to map the shrine change from before the policy to after to determine areas of change. An emphasis on centrality from the capital in …

Heat Shock Protein 90: A Potential Therapeutic Target In Leukemic Progenitor And Stem Cells Harboring Mutant Bcr-Abl Resistant To Kinase Inhibitors, C Peng, Dongguang Li, L Shaoguang

Research outputs pre 2011

Development of drug resistance has become a major obstacle for tyrosine kinase inhibitors (TKIs) in the treatment of Philadelphia chromosome-positive (Ph+) chronic myelogenous leukemia (CML) and other cancers. The BCR-ABL-T315I mutant does not respond to clinically available TKIs, although some newly developed anti-BCR-ABL-T315I TKIs are now being tested in patients. TKIs transiently inhibit kinase activity of BCR-ABL, but do not reduce the level of the BCR-ABL protein. Elimination of mutant BCR-ABL protein would provide a new therapeutic strategy for treating Ph+ leukemia. We recently showed that inhibition of heat shock protein 90 (Hsp90) by a novel Hsp90 inhibitor, IPI-504, causes …

Critiquing The School Community: A Qualitative Study Of Children's Conceptualization Of Their School, Julie Ann Pooley, Lauren Breen, Lisbeth T. Pike, Lynne Cohen, Neil M. Drew

Research outputs pre 2011

Schools are traditionally seen as responsible for the educational outcomes of our children. However, schools also play an important role in the development of aspects such as selfefficacy, participation, competence and self-determination. As schools are often run as societies rather than communities, they offer little opportunity for these attributes (selfefficacy, participation, competence and self-determination) to develop. Forty-six children aged from nine to 12 years were interviewed to ascertain their conceptualizations of the school community. The children define their school in terms of people, places for activities and interaction, a place for safety, cooperation, influence and functionality. The responses closely align …

Fibre Bragg Grating Sensors For Acoustic Emission And Transmission Detection Applied To Robotic Nde In Structural Health Monitoring, Graham Wild, Steven Hinckley Jan 2007

Fibre Bragg Grating Sensors For Acoustic Emission And Transmission Detection Applied To Robotic Nde In Structural Health Monitoring, Graham Wild, Steven Hinckley

Research outputs pre 2011

Distributed acoustic emission sensors are used in structural health monitoring (SHM) for the detection of impacts and/or strain, in real time. Secondary damage may result from the initial impact or strain. This damage may include surface pitting, erosion, or cracking. This type of damage may not be detectable by the SHM system, specifically in passive fiber optic based sensing systems. The integration of non-destructive evaluation (NDE) by robots into SHM enables the detection and monitoring of a wider variety of damage. Communicating via acoustic transmissions represents a wireless communications method for use by NDE inspection robots to communicate with an …

Providing Qos For Symmetrical Voice/Video Traffic In Wireless Networks, Justin Wyatt, Daryoush Habibi, Iftekhar Ahmad, Hushairi Zen

Research outputs pre 2011

Voice over IP (VoIP) and voice-video over IP (VIoIP) are becoming very popular and widespread. These types of real-time services produce streams that are almost symmetrical in nature. A new token passing media access control (MAC) developed by our group, called wireless token network (WTN), has been designed with QoS guarantees in mind. We have previously shown in our previous paper (2006) that WTN supports a higher number of VoIP clients compared to 802.11e due to its higher channel efficiency. In this paper we show that WTN also provides superior QoS for bidirectional streams such as VIoIP due to a …

Adaptive Segregation-Based Mac Protocol For Real-Time Multimedia Traffic In Wlans, Hushairi Zen, Daryoush Habibi, Alexander Rassau, Justin Wyatt Jan 2007

Adaptive Segregation-Based Mac Protocol For Real-Time Multimedia Traffic In Wlans, Hushairi Zen, Daryoush Habibi, Alexander Rassau, Justin Wyatt

Research outputs pre 2011

Wireless local area networks (WLANs) have become very popular both in private and public sectors. Despite the fast expansion of WLANs in various environments, quality of service (QoS) issues for multimedia applications in WLANs are not yet resolved. Multimedia applications contain traffic that are sensitive to delay and jitter and therefore a best-effort protocol such as the legacy IEEE 802.11 is not suitable. The 802.11e protocol provides prioritization and classification of traffic to offer better QoS for real-time services. However, it leaves the design and implementation of many important optimization features to vendors. In this paper we introduce a mechanism …

Rerouting Technique For Faster Restoration Of Preempted Calls, Iftekhar Ahmad, Joarder Kamruzzaman, Daryoush Habibi Jan 2007

Rerouting Technique For Faster Restoration Of Preempted Calls, Iftekhar Ahmad, Joarder Kamruzzaman, Daryoush Habibi

Research outputs pre 2011

In a communication network where resources are shared between instantaneous request (IR) and book-ahead (BA) connections, activation of future BA connections causes preemption of many on-going IR connections upon resource scarcity. A solution to this problem is to reroute the preempted calls via alternative feasible paths, which often does not ensure acceptably low disruption of service. In this paper, a new rerouting strategy is proposed that uses the destination node to initiate the rerouting and thereby reduces the rerouting time, which ultimately improves the service disruption time. Simulations on a widely used network topology suggest that the proposed rerouting scheme …

Network Engineering For C-Commerce Innovation: The Role Of Trust, Mark Brogan, Leisa Armstrong

Research outputs pre 2011

The idea that social networks play an important role in knowledge diffusion of innovation has a long pedigree in innovation theory. In his Diffusion of Innovation (DOI) theory, Rogers (1995) argued that in the information network of the organization, managerial champions and opinion leaders could affect both organizational acceptance and also the velocity of adoption of innovation. In Small to Medium Enterprise (SME) C-commerce innovation, the role of such social factors has been understood in terms of ‘embedded network structure’ (Braun, 2003) that impacts on clustering behavior. This article explores the use of quantitative Social Network Analysis (SNA) to model …

Optimization Of Liquid-Crystal Spatial Light Modulator For Precise Phase Generation, Seow-Hwang Eng, Dong Mei Cai, Zhenglin Wang, Kamal Alameh, Wenhan Jiang

Research outputs pre 2011

Spatial light modulators (SLMs) are recently emerging as wavefront generation or reconstruction devices. In this paper, we use a liquid-crystal SLM (LC-SLM) as a wavefront generation device through the modulation of the spatial phase distribution of an incident light beam. We characterize the phase modulation performance of the LC-SLM, and identified a polarization-configuration to minimize its amplitude modulation effects in order to maximize the contrast of reconstructed phase holograms. We also investigated the feasibility of determining the optical surface uniformity of the LC-SLM through computations of the interference fringes, and identified the disadvantages of this method. This new approach may …

Experimental Demonstration Of A Dynamic 10gbit/S Wdm Header/Label Recognition Structure, Muhsen Aljada, Kamal Alameh, Byeong Ha Lee, Yong Tak Lee, Kiegon Im, Se-Jong Baik

Research outputs pre 2011

In this paper, we experimentally demonstrate a dynamic wavelength-division-multiplexing (WDM) header/label recognition structure that processes on-the-fly WDM patterns. An opto-VLSI processor is used to dynamically generate digital phase holograms that control the wavelength components of the label/header to create digital wavelength profiles. An autocorrelation function of a high-peak is generated when a label bit pattern matches a digital wavelength profile. The main attractive feature of using an opto-VLSI processor is that the lookup table of matching digital wavelength profiles does not need modification when the data bit-rate is upgraded. The dynamic pattern recognition structure is experimentally demonstrated at 10 Gbit/s …

Experimental Demonstration Of A Tunable Laser Using An Soa And An Opto-Vlsi Processor, Muhsen Aljada, Rong Zheng, Kamal Alameh, Yong Lee

Research outputs pre 2011

In this paper we propose and experimentally demonstrate a tunable laser structure cascading a semiconductor optical amplifier (SOA) that generates broadband amplified spontaneous emission and a reflective Opto-VLSI processor that dynamically reflects arbitrarily wavelengths and injects them back into the SOA, thus synthesizing an output signal of variable wavelength. The wavelength tunablility is performed using digital phase holograms uploaded on the Opto-VLSI processor. Experimental results demonstrate a tuning range from 1524nm to 1534nm, and show that the proposed tunable laser structure has a stable performance.
