Athletic training is an allied health profession recognized by the American Medical Association requiring certification by examination. There are two routes towards certification as an athletic trainer: attending a university with an accredited athletic training program or with an internship program By 2004, the only route towards certification will be by attending a Commission on Accreditation of Allied Health Education Programs (CAAHEP) or National Athletic Trainers' Association (NATA) accredited athletic training program. CAAHEP looks at passing rates on the NATA Board of Certification (NATABOC) examination when granting accreditation. This study examined characteristics of programs associated with first time passing rates. ^ Directors from 39 CAAHEP or NATA accredited athletic training programs completed a descriptive 17-question survey regarding academic characteristics, faculty characteristics, and program characteristics. Analysis used Spearman's rho correlation coefficient, with significance of p = <.05. Four program directors were interviewed to gather additional insight. ^ There were three program characteristics that showed a significant positive association with first attempt passing rates: the number of full-time and part-time approved clinical instructors (ACIs)...

This study reports one of the first controlled studies to examine the impact of a school based positive youth development program (Lerner, Fisher, & Weinberg, 2000) on promoting qualitative change in life course experiences as a positive intervention outcome. The study built on a recently proposed relational developmental methodological metanarrative (Overton, 1998) and advances in use of qualitative research methods (Denzin & Lincoln, 2000). The study investigated the use the Life Course Interview (Clausen, 1998) and an integrated qualitative and quantitative data analytic strategy (IQ-DAS) to provide empirical documentation of the impact the Changing Lives Program on qualitative change in positive identity in a multicultural population of troubled youth in an alternative public high school. The psychosocial life course intervention approach used in this study draws its developmental framework from both psychosocial developmental theory (Erikson, 1968) and life course theory (Elder, 1998) and its intervention strategies from the transformative pedagogy of Freire's (1983/1970). ^ Using the 22 participants in the Intervention Condition and the 10 participants in the Control Condition, RMANOVAs found significantly more positive qualitative change in personal identity for program participants relative to the non-intervention control condition. In addition...

Public health data show that African-Americans have not adopted health-promoting behaviors of diet and exercise. Spirituality, important in the lives of many African-American women, may be associated with health-promoting behaviors. This study was designed to determine how spirituality relates to health-promoting behaviors in African-American women. Burkhardt's theoretical framework for spirituality was adopted and measures were selected for the three elements of the framework: connectedness with self, others, and environment. ^ The study used a descriptive cross sectional correlational design to investigate the relationships of the independent variables of spirituality, sociodemographics, and BMI, to the dependent variables of diet and exercise, to answer the two primary questions: What is the role of spirituality in impacting the health-promoting behaviors of African-American women? Of the independent variables of spirituality, sociodemographics, and BMI, which are the best predictors of diet and exercise? ^ Central and South Floridian African-American women (n = 260) between 18 and 82 years of age completed several questionnaires: Rosenberg's Self-Esteem Scale, Health Promoting Lifestyle Profile II, Spiritual Perspective Scale...

The standard highway assignment model in the Florida Standard Urban Transportation Modeling Structure (FSUTMS) is based on the equilibrium traffic assignment method. This method involves running several iterations of all-or-nothing capacity-restraint assignment with an adjustment of travel time to reflect delays encountered in the associated iteration. The iterative link time adjustment process is accomplished through the Bureau of Public Roads (BPR) volume-delay equation. Since FSUTMS' traffic assignment procedure outputs daily volumes, and the input capacities are given in hourly volumes, it is necessary to convert the hourly capacities to their daily equivalents when computing the volume-to-capacity ratios used in the BPR function. The conversion is accomplished by dividing the hourly capacity by a factor called the peak-to-daily ratio, or referred to as CONFAC in FSUTMS. The ratio is computed as the highest hourly volume of a day divided by the corresponding total daily volume. ^ While several studies have indicated that CONFAC is a decreasing function of the level of congestion, a constant value is used for each facility type in the current version of FSUTMS. This ignores the different congestion level associated with each roadway and is believed to be one of the culprits of traffic assignment errors. Traffic counts data from across the state of Florida were used to calibrate CONFACs as a function of a congestion measure using the weighted least squares method. The calibrated functions were then implemented in FSUTMS through a procedure that takes advantage of the iterative nature of FSUTMS' equilibrium assignment method. ^ The assignment results based on constant and variable CONFACs were then compared against the ground counts for three selected networks. It was found that the accuracy from the two assignments was not significantly different...

Parent involvement (PI) in schooling has consistently been correlated with improved academic achievement in children. However, despite the apparent benefits of parent involvement, many schools serving low-income communities report consistent difficulty in facilitating the involvement of parents in their children's schooling. ^ The purpose of this exploratory pilot study was to examine key variables associated with a PI program at a school that served a low-income community. The program was selected because it sustained the involvement of parents for a prolonged period of time. It was also selected because the program was facilitated by social workers. ^ Derived from the literature, four lines of inquiry were examined: (a) the relationship between PI and parent strengths and development; (b) the relationship between PI and children's academic achievement; (c) facilitators for PI; and (d) barriers to PI. These lines of inquiry yielded the study's four primary research questions. The study employed a cross-sectional research design to address them. ^ Thirty-three parents, representing 16 school-involved (SI) parents and 17 non-school involved (NSI) parents, served as study participants. All 33 parents resided in a high poverty community. ^ Quantitative methods were selected to examine differences between study participants and PI. Measures of parental empowerment...

The purpose of this study was to investigate the common factors and experiences that contribute to the success of high ability Black students enrolled in Frank C. Martin Elementary School, the first school in Florida authorized to offer the International Baccalaureate (IB) Primary Years Programme (PYP). The study further sought to determine ways in which educators and stakeholders assisted in maintaining and in increasing Black students' achievement that motivated and encouraged them to pursue similar programs at the middle and high school levels. ^ Three sources of data were used: (a) individual interviews with fourth and fifth grade high ability Black students using a semi-structured format elicited discussion of their perceptions of the PYP and factors contributing to their success; (b) individual interviews with their fourth and fifth grade teachers elicited discussion of teacher expectations and effective instructional strategies; and (c) a questionnaire asked parents of the participating students their reasons for choosing the PYP, their perceptions of the program, and their own level of involvement in their child's learning. Three separate focus groups gathered further data. ^ The results revealed that the factors contributing to the success of high ability Black elementary school students are consistent with those of students in other racial groups. These are a challenging program...

El discurso vindicatorio de Juan Goytisolo y Zoe Valdes: Deconstruccion y recodificacion del lenguaje hegemonico

The goal of this dissertation is to explore the use of transgressive language in the works of Juan Goytisolo and Zoé Valdés. This study examines the socio-political and cultural contexts in which the narrative of both authors develops, as well as the textual devices employed by these writers for undermining the “official history” imposed by the dictatorial regimes in Francoist Spain and Castro's Cuba. Furthermore, this dissertation argues that the deconstructing strategies in Goytisolo and Valdés mark their literary trajectory. Their vindicatory standpoints seek an alternative discourse of national identity. ^ The function of language in demythifying and recodifying hegemonic discourse is examined in Goytisolo's trilogy Señas de identidad, Reivindicación del conde don Julián, and Juan sin tierra; and the novels of Zoé Valdés La nada cotidiana and Te di la vida entera. The parallelisms in the literary works of Goytisolo and Valdés are established by contrasting the authors' revisionist approach to history, the self-reflexivity of their novels, the sexual referent, and the use of irony and parody. The theoretical framework incorporates poststructuralist theorists such as Todorov, Foucault, Lacan, Barthes, Derrida, and Kristeva; the psychoanalytical theory of Freud; and the feminist theories of Cixous and Irigaray. The comparative approach of this study and the interplay of power...

Despite a history of grappling with educational standards, never before has the federal government attempted to establish explicit national standards for what American children should learn in school. Recently, U.S. educators have developed voluntary national content standards, or explicit expectations of what students should know and be able to do. Not surprisingly, this major curriculum reform has provoked considerable debate. Today, teachers face difficult challenges working towards the implementation of standards. The objective of this study was to describe and explain the perceptions of a selected team of fourth-grade teachers regarding the language arts component of their state's Sunshine State Standards (SSS). The exploratory questions that guided this qualitative study were: (a) How are the SSS perceived by these fourth-grade teachers? (b) In what ways do the SSS affect teachers' self-perceptions? and, (c) To what extent and how do the SSS affect the participants' professional classroom behavior? ^ Direct observations, interviews, analysis of relevant documents and the researcher's critical reflective journal served as the methods of inquiry employed in this qualitative study. Bandura's Teacher Self-Efficacy Scale was used as a tool to help categorize the data specifically related to self-perception. ^ Analysis of the data suggests that participants perceived the SSS as a useful guideline as they taught. The SSS were a decisive factor in teachers' planning. They were the actual guide lines used by teachers to plan their lessons. However...

In the wake of the “9-11” terrorists' attacks, the U.S. Government has turned to information technology (IT) to address a lack of information sharing among law enforcement agencies. This research determined if and how information-sharing technology helps law enforcement by examining the differences in perception of the value of IT between law enforcement officers who have access to automated regional information sharing and those who do not. It also examined the effect of potential intervening variables such as user characteristics, training, and experience, on the officers' evaluation of IT. The sample was limited to 588 officers from two sheriff's offices; one of them (the study group) uses information sharing technology, the other (the comparison group) does not. Triangulated methodologies included surveys, interviews, direct observation, and a review of agency records. Data analysis involved the following statistical methods: descriptive statistics, Chi-Square, factor analysis, principal component analysis, Cronbach's Alpha, Mann-Whitney tests, analysis of variance (ANOVA), and Scheffe' post hoc analysis. ^ Results indicated a significant difference between groups: the study group perceived information sharing technology as being a greater factor in solving crime and in increasing officer productivity. The study group was more satisfied with the data available to it. As to the number of arrests made...

Perceptions of alibi evidence as a function of the strength of incriminating *evidence

Português
The current study investigated the exculpatory value of alibi evidence when presented together with various types of incriminating evidence. Previous research has reported that alibi evidence could weaken the effects of DNA evidence and eyewitness identification. The present study assessed the effectiveness of alibi evidence in counteracting defendant's confession (experiment 1) and eyewitness evidence (experiment 2). In experiment 1, three levels of alibi evidence (none, weak, strong) were combined with three levels of confession evidence (voluntary, elicited under low pressure, elicited under high pressure). Results indicated significant main effects of confession and alibi and an alibi by confession interaction. Of participants exposed to high-pressure confession, those in the strong alibi condition rendered lower guilt estimates than those in the no alibi condition. In experiment 2, three levels of alibi were combined with two levels of eyewitness evidence (bad view, good view). A main effect of alibi was obtained, but no interaction between alibi and eyewitness evidence. ^ An explanation of this pattern is based in part on the Story Model (Pennington & Hastie, 1992) and a novel “culpability threshold” model of juror decision-making. The Story Model suggests that jurors generate verdict stories (interpretations of events consistent with a guilty or not guilty verdict) based on trial evidence. If the evidence in favor of guilt exceeds jurors' threshold for perceiving culpability...

Arthritis is the most common chronic condition affecting older people and is a major cause of limited activity. Arthritis education programs in English have demonstrated a positive impact on health but these programs have not reached the Hispanic communities where arthritis is the leading cause of disability. Minorities, such as Hispanics, have traditionally been reluctant to pursue self-help programs, and have been identified as an under-served population in terms of medical care. This study examined the effectiveness of one community health adult education program targeting Hispanic older adults with arthritis, the Spanish Arthritis Self Management Education Program (SASMEP), by evaluating changes in the participants' general health, pain, disability, self-efficacy, health perceptions, frequency of physician visits, and exercise. A pre and post control group experimental design and analyses of covariance were used to determine the pre and post differences in health status and health behaviors for a group participating in the SASMEP and a group who did not using gender and age as covariates. A repeated measures design was also used, and repeated measures analyses of variance and post hoc tests were done on health status and health behavior data collected pre...

The purpose of this study was to compare the efficacy and performance evaluations of alternatively certified first-year teachers to traditionally certified first-year teachers. The participants were 25 first-year teachers in the Broward County Public School District (FL) who completed the Transition to Teaching alternative certification program and a comparison group of 32 first-year teachers in the same school district who completed a traditional university teacher preparation program. ^ The study was a mixed methods design (Creswell, 2003; Tashakkori & Teddlie, 1998). The quantitative data were collected during the 2002–2003 school year using the Teachers' Sense of Efficacy Scale (Tschannen-Moran & Hoy, 2001) and the Florida Performance Measurement System formative and summative instruments. The qualitative data consisted of focus group interviews that were conducted at the end of the 2002–2003 school year. ^ Data were analyzed using independent samples t tests to compare the means of the two populations on their efficacy scores and performance evaluations. Paired samples t tests and analysis of covariance (ANCOVA) were used to compare the efficacy scores for each certification type at the beginning of the school year to the efficacy scores at the end of the school year. A repeated measures analysis of variance (ANOVA) was used to compare the change in the efficacy scores of the teachers from the beginning of the school year to the end of the school year. Focus group interviews were conducted and transcribed...

Structure-based modeling of head -related transfer functions towards interactive customization of binaural sound systems

Português
One of the most popular techniques for creating spatialized virtual sounds is based on the use of Head-Related Transfer Functions (HRTFs). HRTFs are signal processing models that represent the modifications undergone by the acoustic signal as it travels from a sound source to each of the listener's eardrums. These modifications are due to the interaction of the acoustic waves with the listener's torso, shoulders, head and pinnae, or outer ears. As such, HRTFs are somewhat different for each listener. For a listener to perceive synthesized 3-D sound cues correctly, the synthesized cues must be similar to the listener's own HRTFs. ^ One can measure individual HRTFs using specialized recording systems, however, these systems are prohibitively expensive and restrict the portability of the 3-D sound system. HRTF-based systems also face several computational challenges. This dissertation presents an alternative method for the synthesis of binaural spatialized sounds. The sound entering the pinna undergoes several reflective, diffractive and resonant phenomena, which determine the HRTF. Using signal processing tools, such as Prony's signal modeling method, an appropriate set of time delays and a resonant frequency were used to approximate the measured Head-Related Impulse Responses (HRIRs). Statistical analysis was used to find out empirical equations describing how the reflections and resonances are determined by the shape and size of the pinna features obtained from 3D images of 15 experimental subjects modeled in the project. These equations were used to yield “Model HRTFs” that can create elevation effects. ^ Listening tests conducted on 10 subjects show that these model HRTFs are 5% more effective than generic HRTFs when it comes to localizing sounds in the frontal plane. The number of reversals (perception of sound source above the horizontal plane when actually it is below the plane and vice versa) was also reduced by 5.7%...

As the nursing profession faces a shortage of nurses, workplace initiatives focused on retaining employees are critical to the United States healthcare industry (Sochalski, 2002). The purpose of this research was to determine whether self-reported intent to stay on the job was related to perceptions of workplace empowerment using Kanter's (1977) theory of organizational empowerment as a framework. ^ The sample consisted of 206 Florida registered nurses. Four self-report scales and a demographic questionnaire were administered by mail. The Conditions for Work Effectiveness Questionnaire (CWEQ; Chandler, 1987), Job Activity Scale (JAS; Laschinger, Kutzscher, & Sabiston, 1993), Organizational Relationships Scale (ORS; Laschinger, Sabiston, & Kutzscher, 1993) and an intent to stay instrument (Kim, Price, Mueller & Watson, 1996) were used to measure perceived access to empowerment structures, perceived formal power, perceived informal power, and intent to stay, respectively. The data were analyzed using descriptive statistics, correlational analysis, and hierarchical regression. ^ Twenty-eight percent of the variance of intent to stay was explained by perceived access to empowerment structures, perceived formal power, and perceived informal power when holding age...

The purpose of this study is to validate the Study Behavior Inventory-High School, an instrument designed to measure study behaviors of high school students and to determine the stability of its scores across populations and across grades. Numerous studies have shown the relationship between the level of students' use of appropriate study behaviors and their levels of academic achievement and this is particularly relevant at a time of increasing demands for school and teacher accountability for their students' academic achievement. ^ The instrument was administered to 3,336 students in grades 9 through 12 in four high schools in diverse parts of the United States. Factor analysis yielded a four factor structure for the instrument and evidence for its construct validity was obtained using convergent and discriminant methods. The four factors include academic self-perception and feelings of low self-efficacy, academic preparation behaviors, time management, and the social nature of taking tests and studying. Internal consistency reliability for the scores on each of the four factors was calculated and found to range between .68 and .87. Finally, confirmatory factor analysis indicated acceptable levels of fit between the factor structure obtained in this study and an earlier one obtained during a pilot study using 800 participants. ^ The SBI-HS appears to be a valid and reliable instrument for the measure of study behaviors in high school students. ^

The purpose of this study was to examine pediatric occupational therapists attitudes towards family-centered care. Specific attributes identified by the literature (professional characteristics, educational experiences and organizational culture) were investigated to determine their influence on these attitudes. Study participants were 250 pediatric occupational therapists who were randomly selected from the American Occupational Therapy Association special interest sections. ^ Participants received a mail packet with three instruments to complete and mail back within 2 weeks. The instruments were (a) the Professional Attitude Scale, (b) the Professional Characteristics Questionnaire, and (c) the Family-Centered Program Rating Scale. There was a 50% return rate. Data analysis was conducted in SPSS using descriptive statistics, correlations and regression analysis. ^ The analysis showed that pediatric occupational therapists working in various practice settings demonstrate favorable attitudes toward family-centered care as measured by the Professional Attitude Scale. There was no correlation between professional characteristics and educational experiences to therapists' attitudes. A moderate correlation (r = .368, p < .05) was found between the occupational therapists attitudes and the organizational culture of their workplaces. A factor analysis was conducted on the organizational culture instrument (FamPRS) as this sample was exclusively pediatric occupational therapists and the original sample was interdisciplinary professionals. Two factors were extracted using a principal components extraction and varimax rotation...

The rewards and sanctions associated with high-stakes testing may induce educators to participate in practices that will ensure the elimination of the scores of low-achieving students from the testing pool. Two ways in which scores may be eliminated is through retention or referral to special education. ^ This study examined the use of these practices at 179 elementary schools in Miami-Dade County Public Schools, the 4th largest school district in the country. Between- and within-subjects designs were analyzed using repeated measures analysis of variance to compare retention and referral to special education practices over a five-year period of time, two years prior to and two years after the implementation of Florida's high-stakes test, the Florida Comprehensive Assessment Test, FCAT. ^ Significant main effects for referral and retention over time were demonstrated. The use of retention steadily increased over the first three years, with its usage maintained during the fourth year. While the use of referral actually decreased from the first to second years, a significant change occurred after the implementation of the FCAT. ^ Examination of the use of these practices according to student and school characteristics revealed significant differences. Increases in the use of referral across time was significant for Black...

The purpose of this study was to evaluate the impact of the ropes course on the self-esteem of undergraduate and graduate students. The ropes course provides challenging experiential activities that facilitate personal confidence and group teamwork. The study relates to adult education, experiential education, and program evaluation within the context of hospitality and tourism management education. Quantitative data were based on the assessment of self-esteem through the completion of the Coopersmith Self-Esteem Inventory (SEI-C) modified for this study. Qualitative data were based on assessment of participants' reflective papers stating their perceptions of the ropes course. ^ The study compared a treatment group (31 undergraduate and 25 graduate students) which participated in the ropes course, and a control group (31 undergraduate and 25 graduate students) which did not participate. Both groups completed the pre- and post-treatment SEI-C at the same time intervals. The quantitative data were analyzed using a two-way repeated-measures analysis of variance (ANOVA). The qualitative data, comprised of reflective papers voluntarily written by 44 (79%) of the treatment group, were coded using four major themes reflecting the students' perceptions about the ropes course. ^ Scores on the pretest and posttest of the SEI-C were not significantly different for the two groups. The qualitative data showed a favorable impact of the ropes course. The discrepancy in the outcomes based on these two measures suggests that the SEI-C self-report paper-and-pencil instrument may not be sufficiently refined to evaluate the complex issue of self-esteem.

This qualitative study used grounded theory methods and purposeful sampling to explore perceptions on caring and being cared-for. Twenty-four adolescent male participants, identified as at-risk for school failure, completed a two phase interview process exploring these phenomena within three relationships; the relationship with the friend, with the most caring person they knew and with the teacher they felt cared for them. ^ Each participant was asked a predetermined set of open questions in an initial semi-structured interview. In addition each participant was encouraged to explore his own reflections on caring. A second interview allowed for member checking and for the participant to continue sharing his meaning of caring and being cared-for. ^ Line by line analysis with open, axial and selective coding was applied to interview transcripts along with a constant comparative method. Results indicated that the core category integrating all other categories was attachment bonding. Participants' stories manifested characteristics of proximity seeking, secure base, safe haven and distress upon involuntary separation from an attachment figure. ^ Strategies facilitating attachment bonding were influenced by the power positions of the relational players. Participants responded positively to the one-caring when they felt cared-for. Results further indicated that participants did not need to feel a sense of belonging in order to feel cared-for. Teacher behaviors indicating openness for authentic connections with students were specific to teacher's friendliness and professional competence. Teachers who nurtured feelings of being cared-for were uncommon in the participants' educational experience. ^ The number of adolescent males leaving high school prematurely is both a personal problem and a social problem. Despite a “mask” of indifference often exhibited by adolescent males at-risk for school failure...

This research investigates a new structural system utilising modular construction. Five-sided boxes are cast on-site and stacked together to form a building. An analytical model was created of a typical building in each of two different analysis programs utilising the finite element method (Robot Millennium and ETABS). The pros and cons of both Robot Millennium and ETABS are listed at several key stages in the development of an analytical model utilising this structural system. Robot Millennium was initially utilised but created an analytical model too large to be successfully run. The computation requirements were too large for conventional computers. Therefore Robot Millennium was abandoned in favour of ETABS, whose more simplistic algorithms and assumptions permitted running this large computation model. Tips are provided as well as pitfalls signalled throughout the process of modelling such complex buildings of this type. ^ The building under high seismic loading required a new horizontal shear mechanism. This dissertation has proposed to create a secondary floor that ties to the modular box through the use of gunwales, and roughened surfaces with epoxy coatings. In addition, vertical connections necessitated a new type of shear wall. These shear walls consisted of waffled external walls tied through both reinforcement and a secondary concrete pour. ^ This structural system has generated a new building which was found to be very rigid compared to a conventional structure. The proposed modular building exhibited a period of 1.27 seconds...
