We assessed perceptions of adaptation cost and adaptation intentions for five drought- specific adaptive behaviors among 550 farmers from 12 villages in the dry zone of Sri Lanka, as well as their attitudes toward risk. Results suggest that perceived adaptation cost and risk attitude are negatively associated with adaptation intentions. The conditional effect of adaptation cost on adaptation intention as …

Professional Conversations Within Self-Contained Classrooms: The Shared Perspectives Of Teachers, Paraprofessionals, And Administrators, Travis Brett Henderson

UNF Graduate Theses and Dissertations

Paraprofessionals in self-contained settings are often involved in helping students to learn the skills to manage their behaviors. A need has been identified for paraprofessionals to join teachers in professional development opportunities in order to better meet the needs of the students who receive their services (Konza & Fried, 2012). By recognizing paraprofessionals as vital members of a student’s educational team (Boudreau & Twigg, 2011), informal professional development opportunities throughout the school day, such as professional conversations, may provide paraprofessionals with opportunities to share their experiences with each other and with their teachers, as well as to make collaborative decisions …

Biometric Encryption System For Increased Security, Ranjith Jayapal

UNF Graduate Theses and Dissertations

Security is very important in present day life. In this highly-interconnected world, most of our daily activities are computer based, and the data transactions are protected by passwords.

Empirical Evaluation Of Cloud Iaas Platforms Using System-Level Benchmarks, Niharika Deval

UNF Graduate Theses and Dissertations

Cloud Computing is an emerging paradigm in the field of computing where scalable IT enabled capabilities are delivered ‘as-a-service’ using Internet technology. The Cloud industry adopted three basic types of computing service models based on software level abstraction: Infrastructure-as-a-Service (IaaS), Platform-as-a-Service (PaaS), and Software-as-a-Service (SaaS). Infrastructure-as-a-Service allows customers to outsource fundamental computing resources such as servers, networking, storage, as well as services where the provider owns and manages the entire infrastructure. This allows customers to only pay for the resources they consume. In a fast-growing IaaS market with multiple cloud platforms offering IaaS services, the user's decision on the selection …

This sparsity challenges search tools to locate relevant documents for users. A review of the challenges to information searches helps to identify the problems and offer suggestions in improving current information search tools. Using the suggestions put forth by the Strategic Workshop on Information Retrieval …

Behavioral And Physiological Assessment Of Zoo-Housed Heterosexual Gorilla (Gorilla Gorilla Gorilla) Troops With Multiple Silverbacks, Kaylin S. Tennant

UNF Graduate Theses and Dissertations

Based on recognized life history traits and ecology, zoos strive to house their gorillas (Gorilla gorilla gorilla) in mixed-sex groups with one mature male or silverback, multiple females, and their offspring. However, successful captive breeding programs and a nearly 50:50 birth sex ratio has created the need to house surplus males in solitary conditions or all-male groups. It is commonly believed that male western gorillas will not tolerate one another in the presence of females; however, multi-male, mixed-sex groups have been observed in the wild. For this reason, some zoos have begun experimenting with this scenario. At the …
