Seasonal activity and road mortality of the snakes of the Pa-Hay-Okee wetlands of Everglades National Park

The current study describes the composition and activity of the snake community of the Pa-hay-okee wetlands of Everglades National Park. The study was conducted from January 1987 to January 1989. Sixteen species were observed, with Thamnophis sauritus, Thamnophis sirtalis, Nerodia fasciata pictiventris, and Agkistrodon piscivorus representing 90.2% of the total sample. The seasonal distribution and activity of the snakes were closely related to fluctuations in the water table. Most activity occurred in the winter months as snakes migrated west following the drying water edge of Shark River Slough. Seventy percent of all snakes observed during this study were either injured or dead on the road. Over 50% of annual mortality occurred during migration. The impact that road mortality is having on the local snake community cannot be ignored. Management options are provided to minimize loss. A comparison is made to the snake community of the Long Pine Key Region of Everglades National Park.

The effects of semantic and syntactic instruction on user performance and satisfaction in search user interface design

The design of interfaces to facilitate user search has become critical for search engines, ecommercesites, and intranets. This study investigated the use of targeted instructional hints to improve search by measuring the quantitative effects of users' performance and satisfaction. The effects of syntactic, semantic and exemplar search hints on user behavior were evaluated in an empirical investigation using naturalistic scenarios. Combining the three search hint components, each with two levels of intensity, in a factorial design generated eight search engine interfaces. Eighty participants participated in the study and each completed six realistic search tasks. Results revealed that the inclusion of search hints improved user effectiveness, efficiency and confidence when using the search interfaces, but with complex interactions that require specific guidelines for search interface designers. These design guidelines will allow search designers to create more effective interfaces for a variety of searchapplications.

New trends in health architecture for children and the effects of the built environment on young patients

The objective of this thesis was to investigate the effects of the built environment on the outcome of young patients. This investigation included recent innovations in children's hospitals that integrated both medical and architectural case studies as part of their design issues. In addition, the intervention responded to man-made conditions and natural elements of the site. The thesis project, a Children's Rehabilitation Hospital, is located at 1500 N.W. River Drive in Miami, Florida. The thesis intervention emerged from a site analysis that focused on the shifting of the urban grid, the variation in scale of the immediate context and the visual-physical connection to the river's edge. Furthermore, it addressed the issues of overnight accommodation for patient's families, as well as sound control through the use of specific materials in space enclosures and open courtyards. The key to the success of this intervention lies in the special attention given to the integration between nature and the built environment. Issues such as the incorporation of nature within a building through the use of vistas and the exploitation of natural light through windows and skylights, were pivotal in the creation of a pleasant environment for visitors, employees and young patients.

Effects of academic integration on the persistence and achievement of under-prepared college students

The purpose of this dissertation was to examine the effect of academic integration, defined in terms of instructor/student contact, on the persistence of under-prepared college students and the achievement of those who persist. The overall design of this study compared instructor-initiated contact with conventional contact. The dependent variables were persistence, achievement, motivation and anxiety. Information was collected by administering the College-Level Mathematics Test (CLM), the Perceived Affective Contact Questionnaire (PAC), the expectancy and anxiety components of the Motivated Strategies for Learning Questionnaire (MSLQ), a departmental final examination, and by accessing university records. The sample consisted of 130 college algebra students at a large, public university with a Hispanic majority. The main analyses consisted of a 2x2x2 ANOVA (treatment by ethnicity by gender) to test for differences in achievement, t-tests to compare motivation, anxiety and perceived affective contact scores for the two groups, Chi-square tests to assess differences in persistence, and Pearson Product-Moment Correlation to determine the relationship between pretest scores and achievement variables. Results indicated that neither instructor-initiated contact, gender nor ethnicity is related to persistence, motivation or anxiety. A significant disordinal interaction of treatment and ethnicity was observed, with Hispanic experimental students scoring significantly higher on a test of algebra achievement than Hispanic control students. Academic integration, defined in terms of instructor/student contact, has a positive influence on the achievement of Hispanic students. This may imply their positive responsiveness to the relational aspect of contact due to traditional cultural values of interdependence, acquiescence to authority and physical closeness. Such interactive feedback is a means by which students with these values are recognized as members of the university academic community, prompting increased academic effort. Training in contact initiation to promote academic integration is implied, by the results of this study, for instructors dealing with first year students, especially instructors at institutions accommodating instructional methods to the needs of diverse groups.

N-acetoxy-N-acetyl-2-aminofluorene binding sites on [phi] X174 and SV40

Restriction enzyme inhibition and lambda exonuclease studies indicate that carcinogen N-acetoxy-N-acetyl-2 aminofluorene (AAAF) binds to sequences on ɸX174 RF and SV40 plasmids DNA that are similar to the eight preferred binding sites previously located on pBR 322. Both DNAs were digested with enzyme Hinf I and resultant fragments 32P end-labeled. Labeled fragments were reacted with the carcinogen to give one to sixteen bound moieties per DNA. Fragments were isolated and restriccion enzyme and lambda exonuclease inhibition assays were performed. Inhibition detected occurred at selected sites and was not specific for a certain enzyme or certain size of recognition sequence. Results of these assays allow mapping of the location of high affinity binding sites of the carcinogen on both DNAs. All sites have common sequence elements: the presence of either the sequence T(G/C)TT(G/C) or the sequence T(G/C) CTT(G/C).

Waveguide microgripper for identification, sensing and manipulation

A Waveguide Microgripper utilizes flexible optical waveguides as gripping arms, which provide the physical means for grasping a microobject, while simultaneously enabling light to be delivered and collected. This unique capability allows extensive optical characterization of the structure being held such as transmission, reflection or fluorescence. One of the simplest capabilities of the waveguide microgripper is to be able to detect the presence of a microobject between the microgripper facets by monitoring the transmitted intensity of light coupled through the facets. The intensity of coupled light is expected to drop when there is an object obstructing the path of light. The optical sensing and characterization function of the microgripper is a strong function of the optical power incident on the structure of interest. Hence it is important to understand the factors affecting the power distribution across the facet. The microgripper is also capable of detecting the fluorescence. This capability of microgripper is expected to have applications in medical, bio-medical and related fields.

Internet Protocol (IP) design and implementation for efficient mobility to devices in wireless networks

The purpose of this thesis was to develop an efficient routing protocol which would provide mobility support to the mobile devices roaming within a network. The routing protocol need to be compatible with the existing internet architecture. The routing protocol proposed here is based on the Mobile IP routing protocol and could solve some of the problems existing in current Mobile IP implementation e.g. ingress filtering problem. By implementing an efficient timeout mechanism and introducing Paging mechanism to the wireless network, the protocol minimizes the number of control messages sent over the network. The implementation of the system is primarily done on three components: 1) Mobile devices that need to gain access to the network, 2) Router which would be providing roaming support to the mobile devices and 3) Database server providing basic authentication services on the system. As a result, an efficient IP routing protocol is developed which would provide seamless mobility to the mobile devices on the network.

The potential of solid phase microextraction (spme) for the recovery of explosives followed by gas and liquid chromatographic analysis

The potential of solid phase microextraction (SPME) in the analysis of explosives is demonstrated. A sensitive, rapid, solventless and inexpensive method for the analysis of explosives and explosive odors from solid and liquid samples has been optimized using SPME followed by HPLC and GC/ECD. SPME involves the extraction of the organic components in debris samples into sorbent-coated silica fibers, which can be transferred directly to the injector of a gas chromatograph. SPME/HPLC requires a special desorption apparatus to elute the extracted analyte onto the column at high pressure. Re suits for use of GC[ECD is presented and compared to the results gathered by using HPLC analysis. The relative effects of controllable variables including fiber chemistry, adsorption and desorption temperature, extraction time, and desorption time have been optimized for various high explosives.

Attitudes and behaviors of pre-adolescents with diabetes toward fat -modified foods

Fat modified foods are widely available and have the potential to help individuals with diabetes, including children, achieve a lower total fat and saturated fat intake. Sixty-three pre-adolescents (10-13 years) with insulin-dependent diabetes mellitus (IDDM or Type I), and 60 without diabetes (boys, n=54; girls, n=69) were tested to determine their beliefs and attitudes towards high-fat and reduced-fat foods. In addition, both children and parents were asked about the child's use of low fat foods i.e., how often the parent bought or encouraged their child to eat reduced-fat food; how strongly the doctor or dietitian promoted the use of reduced-fat foods, and the child's concern about dietary fat. In this study, preadolescents with diabetes were not more likely than those without diabetes to use fat-modified foods. Parental and health care practitioner encouragement is associated with greater use of these products by children.

The relationship between Common Language and Length of Treatment in Occupational Therapy

The diversity of ethnic and cultural groups and the effects of language in the therapeutic relationship are timely professional issues of concern to occupational therapy practitioners. The tri-ethnic, tri-cultural South Florida area offers a natural environment where one can study how patient-therapist interactions are influenced by language barriers in a diverse society. This study examines the effects of language on the adequacy of occupational therapy services, specifically how language affects the length of the treatment program. The nature of diagnosis therapists' ethnicity, and how they impact treatment outcomes are also addressed. A sample was drawn from the occupational therapy outpatient department of a large county hospital. Data taken from patients' charts examined race, sex, age, diagnosis, and language. Number of treatment sessions and length of treatment were viewed as proxy measures for adequacy. Findings indicate that the effect of language cannot be understood aside from ethnicity. Implications for occupational therapy practice are discussed.

International tourism and socio-economic development in the Caribbean : are they compatible?

Plagued with poverty, the countries of the Caribbean have grappled for years with numerous development models. As in many Third World countries, tourism has been used as an economic development strategy. Criticisms of the tourism industry have frequently been severe. So much that during the formation of the Caribbean Basin Initiative, the tourism industry was intentionally avoided and other industries favored. One of the most critical questions asked of tourism is whether or not the economic gains of the industry are worth the detrimental social, political and environmental effects on the host country. It is the objective of this thesis to examine the relationship between international tourism and socio-economic development in the Caribbean, and to determine whether or not the deficiencies of the industry prevent it from being a beneficial development tool.

Once a Catholic : a novel in stories and poems

"Once A Catholic" is a novel about the indelible effects of growing up Catholic. The novel is told in a series of stories and poems. The first story, "Credo," offers an overview of the rich culture of Catholicism that binds the Daley family together. "Before The Fall" recalls the safety and warmth of that Catholic faith. Subsequent stories focus on individual family members and events, and the Catholicity that lies at their core. "Holy Orders" tells the story the firstborn male child whose destination is the priesthood. "Finding Ecstasy" is a daughter's story of rebellion through sexual exploration. "Sweet Reconciliation" is the story of a search within oneself for forgiveness, the cornerstone of Catholic upbringing. "Acts of the Apostle" demonstrates the hopelessness of a faith under attack. The final story, "Holy Relics," demonstrates the never-ending desire for redemption and the important act of returning sacredness to its rightful place.

Analysis and comparison of network performance with different network parameters

The purpose of this study was to analyze the network performance by observing the effect of varying network size and data link rate on one of the most commonly found network configurations. Computer networks have been growing explosively. Networking is used in every aspect of business, including advertising, production, shipping, planning, billing, and accounting. Communication takes place through networks that form the basis of transfer of information. The number and type of components may vary from network to network depending on several factors such as requirement and actual physical placement of the networks. There is no fixed size of the networks and they can be very small consisting of say five to six nodes or very large consisting of over two thousand nodes. The varying network sizes make it very important to study the network performance so as to be able to predict the functioning and the suitability of the network. The findings demonstrated that the network performance parameters such as global delay, load, router processor utilization, router processor delay, etc. are affected. The findings demonstrated that the network performance parameters such as global delay, load, router processor utilization, router processor delay, etc. are affected significantly due to the increase in the size of the network and that there exists a correlation between the various parameters and the size of the network. These variations are not only dependent on the magnitude of the change in the actual physical area of the network but also on the data link rate used to connect the various components of the network.
