Assisted Living: The Need for Creation of Affordable Options

Assisted Living: The Need for Creation of Affordable Options

Access: Use of this item is restricted to the UNT Community.
Date: August 2000
Creator: Kretzinger, Robert W.
Description: Assisted living, the fastest growing segment of the senior housing industry, allows individuals to remain as independent as they prefer and still receive necessary services. However, assisted living residences exist primarily to serve those seniors who can pay for the services from their own savings/income. We are facing a critical need for housing options for both the current senior generation and the soon-to-be-retired baby boomers. How will access to assisted living be opened to all types of payors? How will states fund the growth of assisted living? The purpose of this paper is to discuss opportunities for expansion that will make assisted living an affordable option for the low- and moderate-income elderly.

Automated defense against worm propagation.

Automated defense against worm propagation.

Access: Use of this item is restricted to the UNT Community.
Date: December 2005
Creator: Patwardhan, Sudeep
Description: Worms have caused significant destruction over the last few years. Network security elements such as firewalls, IDS, etc have been ineffective against worms. Some worms are so fast that a manual intervention is not possible. This brings in the need for a stronger security architecture which can automatically react to stop worm propagation. The method has to be signature independent so that it can stop new worms. In this thesis, an automated defense system (ADS) is developed to automate defense against worms and contain the worm to a level where manual intervention is possible. This is accomplished with a two level architecture with feedback at each level. The inner loop is based on control system theory and uses the properties of PID (proportional, integral and differential controller). The outer loop works at the network level and stops the worm to reach its spread saturation point. In our lab setup, we verified that with only inner loop active the worm was delayed, and with both loops active we were able to restrict the propagation to 10% of the targeted hosts. One concern for deployment of a worm containment mechanism was degradation of throughput for legitimate traffic. We found that with proper ...

Automatic Software Test Data Generation

Automatic Software Test Data Generation

Creator: Munugala, Ajay Kumar
Description: In software testing, it is often desirable to find test inputs that exercise specific program features. Finding these inputs manually, is extremely time consuming, especially, when the software being tested is complex. Therefore, there have been numerous attempts automate this process. Random test data generation consists of generating test inputs at random, in the hope that they will exercise the desired software features. Often the desired inputs must satisfy complex constraints, and this makes a random approach seem unlikely to succeed. In contrast, combinatorial optimization techniques, such as those using genetic algorithms, are meant to solve difficult problems involving simultaneous satisfaction of many constraints.

Creator: Akinola, Adeniyi O.
Description: Baeyer-Villiger oxidation of 1,9-dibromopentacyclo[5.4.0.02,6.03,10.05,9]undecane-8,11-dione (1,9-dibromo-PCU-8,11-dione) was performed by using an excess amount of m-chloroperbenzoic acid (3 equivalents) and resulted in the formation of the corresponding monolactone. The reaction would not proceed to the dilactone stage. The structure of the reaction product was established unequivocally via single crystal X-ray diffraction. Baeyer-Villiger oxidation of 1,9-dibromo-PCU-8,11-dione using ceric ammonium nitrate (CAN) was also performed and afforded a mixture of lactones. Only one of these lactones, which also contained an alkene functionality, could be isolated and characterized. 1,7-dibromo-PCU-8,11-dione was also reacted with CAN, yielding the mono-lactone, which has also been characterized.

Barriers Limiting Access to Hospice Care for Elderly African Americans in Amarillo, Texas

Barriers Limiting Access to Hospice Care for Elderly African Americans in Amarillo, Texas

Access: Use of this item is restricted to the UNT Community.
Date: August 2001
Creator: Anthony, Tomagene
Description: This study examines barriers limiting access to hospice care for elderly African Americans. Ethnic background plays a critical role in the development of attitudes, beliefs and expectations related to death and issues surrounding hospice care. The purpose of this study was to identify barriers that may limit access to hospice care for African Americans. A questionnaire was administered to 56 elderly African Americans in three religious settings and an African American senior citizens center. The questionnaire was designed to obtain information concerning African Americans' attitudes toward death and dying; religious beliefs; health beliefs; familiarity with hospice and prospective use of hospice. The results of the study indicate a number of barriers in access to hospice care for African Americans including: hospice knowledge barriers; education/outreach barriers; cultural knowledge barriers related to death/dying values; family/social support barriers; hospice organizational/provider barriers; health care organizational/provider barriers; and reimbursement barriers.

Between the Waves: Truth-Telling, Feminism, and Silence in the Modernist Era Poetics of Laura Riding Jackson and Muriel Rukeyser

Between the Waves: Truth-Telling, Feminism, and Silence in the Modernist Era Poetics of Laura Riding Jackson and Muriel Rukeyser

Access: Use of this item is restricted to the UNT Community.
Date: December 2006
Creator: Cain, Christina
Description: This paper presents the lives and early feminist works of two modernist era poets, Laura Riding Jackson and Muriel Rukeyser. Despite differences of style, the two poets shared a common theme of essentialist feminism before its popularization by 1950s and 60s second wave feminists. The two poets also endured periods of poetic silence or self censorship which can be attributed to modernism, McCarthyism, and rising conservatism. Analysis of their poems helps to remedy their exclusion from the common canon.

Creator: Skebe, Carolyn Alifair
Description: A fifty page manuscript of poetry and a critical introduction detailing the poet's aesthetics. Using the idea of the double-image and eroticism, the poet places her work in the category of the surreal. She describes the process of writing poetry born of fragmentary elements as a feminist emergence of agency. The manuscript is composed of four sections, each an element in the inevitable breakdown of a love relationship: meeting, love-making, birth of a child, death. Quotes from various authors of anthropological and fictional texts begin each section to reinforce thematic structure in a process of unveiling the agency of the narrator. The poems are organized as a series, beginning and ending with sequence poems.

Bounded Dynamic Source Routing in Mobile Ad Hoc Networks

Bounded Dynamic Source Routing in Mobile Ad Hoc Networks

Access: Use of this item is restricted to the UNT Community.
Date: August 2003
Creator: George, Glyco
Description: A mobile ad hoc network (MANET) is a collection of mobile platforms or nodes that come together to form a network capable of communicating with each other, without the help of a central controller. To avail the maximum potential of a MANET, it is of great importance to devise a routing scheme, which will optimize upon the performance of a MANET, given the high rate of random mobility of the nodes. In a MANET individual nodes perform the routing functions like route discovery, route maintenance and delivery of packets from one node to the other. Existing routing protocols flood the network with broadcasts of route discovery messages, while attempting to establish a route. This characteristic is instrumental in deteriorating the performance of a MANET, as resource overhead triggered by broadcasts is directly proportional to the size of the network. Bounded-dynamic source routing (B-DSR), is proposed to curb this multitude of superfluous broadcasts, thus enabling to reserve valuable resources like bandwidth and battery power. B-DSR establishes a bounded region in the network, only within which, transmissions of route discovery messages are processed and validated for establishing a route. All route discovery messages reaching outside of this bounded region are dropped, thus ...

The Break-up of the Confederate Trans-Mississippi Army, 1865

The Break-up of the Confederate Trans-Mississippi Army, 1865

Access: Use of this item is restricted to the UNT Community.

Creator: Clampitt, Brad R.
Description: Unlike other Confederate armies at the conclusion of the Civil War, General Edmund Kirby Smith's Trans-Mississippi Army disbanded, often without orders, rather than surrender formally. Despite entreaties from military and civilian leaders to fight on, for Confederate soldiers west of the Mississippi River, the surrender of armies led by Generals Robert E. Lee and Joseph E. Johnston ended the war. After a significant decline in morale and discipline throughout the spring of 1865, soldiers of the Confederate Trans-Mississippi Department chose to break-up and return home. As compensation for months of unpaid service, soldiers seized both public and private property. Civilians joined the soldiers to create disorder that swept many Texas communities until the arrival of Federal troops in late June.
