One of the important branches of government and vital to the community, police agencies are organizations that have high usage rates of information technology systems since they are in the intelligence sector and thus have information incentives. Not only can information technologies develop intra- and inter-relationships of law enforcement agencies, but they also improve the efficiency and effectiveness of the police officers and agencies without adding additional costs. Thus, identifying the factors that influence the police officers' adoption of information technology can help predict and determine how information technology will contribute to the social organization of policing in terms of effectiveness and efficiency gains. A research framework was developed by integrating three different models, theory of planned behavior (TPB), technology acceptance theory (TAM), and diffusion of innovation theory (DOI) while adding two other factors, facility and voluntariness, to better determine the factors affecting the implementation and adoption of the POLNET software system used by the Turkish National Police (TNP). The integrated model used in this study covers not only basic technology acceptance factors, but also the factors related to policing. It also attempts to account for the factors of cultural differences by considering the important aspects of Turkish culture. A …

The purposes of the present study are to: (a) describe the beliefs and practices of the US and Taiwan (TW) public and private kindergarten teachers regarding developmentally appropriate practice (DAP), (b) examine the group differences between the four groups of teachers, and (c) identify the salient factors related to the variability of developmentally appropriate beliefs and practice in these teachers. Three hundred and fifty-seven kindergarten teachers participated in the study. The group sizes were 123, 123, 57, and 54 for Taiwan private, Taiwan public, US private, and US public kindergarten teachers, respectively. A survey was used to collect data. Findings from this study showed: (a) Both the US and Taiwan kindergarten teachers highly endorsed beliefs about DAP; (b) US and Taiwan kindergarten teachers also held strong beliefs about developmentally inappropriate practices (DIP); (c) DAP activities occurred regularly in the classrooms; (d) developmentally inappropriate practice (DIP) activities also took place a lot although they were lower than the DAP activities; (e) the Taiwan teachers had higher beliefs about DAP and lower beliefs about DIP than the US teachers; (f) the US teachers reported both higher DAP and DIP activities than the Taiwan teachers; (g) there were no differences between public and …

Innovative educators seek technologies to facilitate or enhance the learning experience while taking nothing away from the message of instruction. Simulations have been shown to meet this requirement. While simulations cannot replace the teacher or the message of instruction, they can provide a deeper and more cognitively engaging learning experience. Classroom use of simulations has been ongoing since the 1960's. However, substantive research on their efficacy remains limited. What research has been conducted indicates that simulations possess great potential as aids to instruction. The author of this dissertation pursued this question focusing on whether simulations contribute to instruction by facilitating transfer, improved motivation and increased engagement. This dissertation documents a study in which instructional simulations were used in undergraduate science courses to promote engagement, transfer and knowledge-seeking behavior. The study took place at Midwestern State University (MSU), a public university located in north-central Texas with a student population of approximately 5,500. The study ran during the fall 2006 and spring 2007 terms. Samples consisted of students enrolled in GNSC 1104 Life / Earth Science during the fall term and GNSC 1204 Physical Science during the spring term. Both courses were offered through the Department of Science and Mathematics at MSU. …

The dissertation explores middle-school students' abilities to engage in historical thinking. I dispute the Hallam-Piaget model, which discourages analytical thinking through the assumption that children lack skills to think critically about history. My historical narrative inquiry model (1) teaches procedural knowledge (the process of "doing" history); (2) enhances interpretative skills; (3) cultivates historical perspectives based upon evidentiary history; and (4) encourages student authorship of historical narratives. In the fall semester of 2006, with a classroom of twenty-five seventh-graders, I initiated a research study designed to explore the impact of the historical narrative inquiry model through a sequence of thirty-two lessons. The lessons involved small- and large-group activities, including oral presentations, discussions about primary documents, and consideration of the relation between narratology and the creation of written history. Students generated their own historical narratives in order to articulate their perspectives. Eight students having varied reading-level proficiency served as primary participants in the study. Each of these students received pre- and post-intervention interviews. Outcomes reflected the enhancement of pedagogy intended to facilitate historical thinking and historical empathy in the classroom.

Language policy reform movements have increased accountability in order for schools to improve student achievement and measure the progress of English language learners. The number of English language learners (ELLs) has grown significantly in the school population, yet the level of academic achievement for this population continues to lag. Language planning and policy provide critical decisions about how to measure what students know in all subjects. In 1999, the 76th Texas Legislature approved the assessment of the state curriculum to account for student learning while nationally the No Child Left Behind Act (NCLB) requires assessment and accountability to measure what students know. Long term English language learners (LTELs) in high school are of particular concern because they have not been able to meet standards on the state's assessments. These assessments are used for national NCLB accountability under Annual Yearly progress (AYP) indicators, the state's accountability and the Texas graduation criteria. The purpose of this study has been to examine the impact of educational language planning and policy on LTELs who have lived and attended US schools for more than four school years.

Admissions processes for health professions programs result in students entering these programs academically homogeneous. Yet some students have great difficulty with the programs. Research has shown a limited ability of traditional academic indicators to predict successful outcomes for health professions education. The purpose of this study was to examine the relationship between learning motivation and academic outcomes for students in health professions programs. The Modified Archer Health Professions Motivation Scale (MAHPMS) and a demographic survey were administered at orientation to 131 medical and 29 physician assistant students at the University of North Texas Health Science Center in the fall of 2005. At the end of the semester, the same version of the MAHPMS was administered, and final course grades and semester averages were collected. Descriptive statistics were analyzed for all the study variables. Analysis of variance was utilized to examine within subjects and between subjects differences for the learning motivation scores among programs and demographic categories. Linear regression analyses were used to determine the relationship between learning motivation scores and end-of-semester grades. And finally, logistic regression was performed to explore the ability of the motivation scores to predict academically high-risk students. Approximately three-fourths of the students indicated a preference for …

Interactional and contextual models have been conceptually proposed in understanding parental influences on children. Yet, empirical model testing has been limited. The purpose of this exploratory study was to investigate the direct and indirect effects of parenting style on child social competence using structural equation modeling in a sample of 544 Chinese families with 6-9 years old children, mainly singleton, residing in Nanjing, China. Five latent models were tested: (a) the direct model between parenting style and child social competence, (b) child temperament as a moderator, (c) parent-child relationship as a mediator, (d) the interaction model between parenting style and family functioning, and (e) bidirectional models of parenting style concurrently with parent-child relationship, and family functioning predicting child social competence. Findings showed: (a) The direct relationship between parenting style and child social competence was significant in both parents with authoritative parenting style on the positive direction, whereas authoritarian and permissive parenting styles on the negative direction; (b) child temperament did not moderate parenting style on child social competence; (c) father-child relationship mediated paternal parenting style on child social competence, whereas maternal parenting style did not; (d) family functioning neither moderated nor mediated the relationship between parenting style and child social …

This study examined what differences in resiliency traits, if any, exist between successful and non-successful first and continuing-generation college students through the use of a survey. For the purposes of this study, first-generation students were those students whose parents have never attended college and continuing-generation college students were those students whose parents have attended some college. For the purposes of this study, the term successful was defined as those students who after being enrolled during fall 2005 re-enrolled for the spring 2006 semester and the term non-successful is defined as those students who after being enrolled fall 2005 semester failed to re-enrolled for the spring 2006 semester. A sample of 164 students was surveyed by collecting demographic data, resiliency traits, attitudinal characteristics, level of familial support, and reasons for dropping out of college. A sub-sample of 40 students participated in a face-to-face, in-depth interview. This study found that successful first-generation community college students possessed certain common qualities or resilient characteristics that include: 1) social competence, 2) problem-solving skills, 3) critical consciousness, 4) autonomy, and 5) sense of purpose. Through the face-to-face interviews common themes emerged. Many of the students used similar words to describe their feelings and experiences about beginning, …

This study replicated and extended previous research I had performed that suggested that a student success course is an effective intervention to assist student-athletes in the adjustment to college. Participants in the current study included 4 groups of students, including (1) non-athletes and (2) student-athletes who were mandated and enrolled in the student success course, and (3) non-athletes and (4) student-athletes who were not mandated and did not enroll in the student success course. Overall, results from the current study suggested that the student success course was effective in helping non-athletes and student-athletes learn key cognitive strategies that are necessary for college success. In addition, results indicated that after taking the student success course, academically at-risk students earned equivalent grades, percentage of hours passed, and retention rates compared to their peers who were not classified as being academically underprepared. Finally, adjustment patterns of all groups were examined, with particular emphasis on the decrease in adjustment over the course of the semester that was demonstrated by the student-athletes. Intervention implications and future research directions are discussed, specifically in terms of how to address the unique needs of college freshmen student-athletes.

This study explores distinct levels of meaning from images of picture books perceived by 3- to 5-year-old children and investigates how the certain visual perception factors influence children's meaning making and if these factors are correlated. The literature review supports associations among visual perception, information, picture books, meaning, and children. Visual perception serves as the first channel that filters and interprets visual information, and picture books provide visual and verbal experience for children, who constantly search for meaning. Children age 3 to 5 years are potential users of picture books because pictorial information is considered useful to children's learning tasks. Previous research reveals that various factors influence visual perception, and meaning has been mostly associated with its semantic significance in information retrieval. In information science, little research has focused on young children's own way of categorizing information, especially visual information. In order to investigate the distinct levels of meaning perceived by children, the investigation employed both qualitative and quantitative methods including unobtrusive and participant observation, factor analysis, content analysis, and case study. The result of this study contributes to understanding the cognitive process of children related to visual literacy and their interpreting visual information in a digital environment.

Analysis of a particular north-central Texas public high school revealed a strong representation of Hispanic females in advanced academic programs, i.e., AP and GT in proportion to their representation in the overall student population. Research seems to indicate that a progressive approach to academic-potential identification; culturally effective mentoring, traditional Hispanic values, and newly emerging personal and social characteristics all seem to be contributing factors. This study seems to indicate that a new type of Hispanic female is emerging who is more assertive academically, more visible in the classroom, and less marriage-and-family oriented as might be believed by teachers, society, their peers, and perhaps even their parents.

This qualitative case study research examined how constructivist problem-based learning facilitated higher level thinking, increased interest in art, and affected attitude toward on-line courses in an undergraduate philosophical aesthetics and interpretation of art criticism course. The research conducted for this study suggests that constructivist problem-based learning does facilitate higher level thinking and increases student interest in art and in on-line classes. Active learning assignments, along with the constructivist collaborative class atmosphere, encouraged students to think more deeply about their personal values concerning art and to consider alternative views. Problem-based learning in this class acted as a scaffold to aid in understanding the material and then in applying the material to unique and real-life situations. Each subject came to the course with certain thinking skills and left with increased knowledge about art but also with increased critical thinking skills for critically examining and discussing art. Participants completed the course with more confidence in their critical thinking ability and in dealing with visual art images. Data was gathered from seven study participants in the form of highly-structured interviews, an early and final critical writing analysis, a major problem assignment and its reflection journal, a beginning survey, and two final surveys. The final …

New product ideation is the transformation of a raw idea into a robust concept with consideration of fit and feasibility of technologies, customer benefits, and market opportunity. Although the ideation process often involves ambiguous processes, it is the most critical activity in new product development (NPD). As a creativity task, the ideation process is considered heuristic rather than algorithmic. However, managing the ideation process as either a completely heuristic or an entirely algorithmic procedure leads to just conventional outcomes. Rooted in cognitive psychology, this study proposes that ideation activities in NPD should be pursued as Simonton's "constrained stochastic behavior." An ideation task not only needs good componential factors but also requires constraint to frame the task by precluding unwieldy ideas while promoting high variability of ideas. Focusing on the inputs and attempting to strike a balance between algorithmic and heuristic ideation process may provide the mechanisms to manage the psychological perceptions with an aim to stimulate and orchestrate the ideation staff's cognitive efforts to generate the creative idea. To achieve this goal, new product idea creativity is considered as the ideas that could turn out to be products that are novel to and useful for customers, and appropriate to firms' …

Over the years there has been significant discussion of the connection between principal's leadership qualities and teacher efficacy. Students come to the classroom from stable, traditional, supportive home environments as well as from unstable, broken, and homeless situations. Teachers are asked to teach a classroom full of students with a wide range of learning abilities as well as a varied range of learning disabilities. The confidence to do this for the measure of a teacher's career takes a strong sense of efficacy. The purpose of this study was to examine the relationship between teachers' sense of efficacy and teachers' perceptions of their principals' leadership qualities that enhance and/or diminish the teachers' sense of efficacy. This study utilized both quantitative and qualitative research methods to study the effects of leadership qualities on teacher efficacy. Quantitative data was acquired utilizing the teacher sense of efficacy scale and the principal leadership questionnaire. Qualitative data was gathered through a focus group meeting of teachers with measurably strong efficacy to identify principal practices that affect teachers' efficacy. The study's outcomes reported that total respondent data indicates a generally positive relationship between these two variables. Subgroup analysis revealed varying results with diminishing relationships measured from elementary …

This research studied the Anderson localization of electrons in two-channel wires with correlated disorder and in DNA molecules. It involved an analytical calculation part where the formula for the inverse localization length for electron states in a two-channel wire is derived. It also involved a computational part where the localization length is calculated for some DNA molecules. Electron localization in two-channel wires with correlated disorder was studied using a single-electron tight-binding model. Calculations were within second-order Born-approximation to second-order in disorder parameters. An analytical expression for localization length as a functional of correlations in potentials was found. Anderson localization in DNA molecules were studied in single-channel wire and two-channel models for electron transport in DNA. In both of the models, some DNA sequences exhibited delocalized electron states in their energy spectrum. Studies with two-channel wire model for DNA yielded important link between electron localization properties and genetic information.

Diabetes has alarming prevalence rates not only in the U.S., but also worldwide. Ethnicity plays a large role with Hispanic-Americans having one of the highest prevalence rates. Diabetes is a complicated disease that requires significant lifestyle modifications. The health belief model (HBM) has been investigated as a theory to explain behavior change. However, little research has been done to determine its utility to Mexican-Americans. In the current study, participants were Mexican-American adults (N = 66) with type II diabetes who were recruited from family medicine clinics. Self-report questionnaires included the General Acculturation Index (GAI) and the Multidimensional Diabetes Questionnaire (MDQ). Participants had the option to complete them in either Spanish or English. Laboratory values were collected from medical charts. A MANCOVA indicated that two variables were significant, perceived severity (PS) and misguided support behaviors (MSB), p < .05. With respect to the HBM, PS was identified as a component of an individual's perception, acculturation was a modifying factor, and MSB was a component of the likelihood to change factors. These three affected glycemic control. Odds ratios determined that individuals with better glycemic control had less perceived severity and less misguided supportive behavior. Individuals with the least acculturation were more likely …

In their efforts to make the selection and hiring process more efficient, school administrators utilize teacher selection instruments such as the Web-based TeacherInsight™ assessment tool (The Gallup Organization, Princeton, NJ). Tools such as these instruments are now used regularly by school systems across the nation to assess teachers regarding their knowledge, talents, skills, attitudes, and values. According to Gallup, the TeacherInsight is a predictor of teacher talent and is based on 12 themes. This study utilized 132 elementary and secondary teachers and approximately 4,500 students currently enrolled in Grades 3 through 11 to determine if the TeacherInsight is a predictor of student achievement. This study considered: (1) the relationship between the TeacherInsight and student achievement as measured by the Texas Growth Index (TGI); (2) the relationship between teacher characteristics (years of experience, level [primary or secondary], gender, age, degree) and the TeacherInsight instrument; (3) the relationship between teacher characteristics (years of experience, level [primary or secondary], gender, age, degree) and student achievement as measured by the TGI; and (4) the relationship between student classifications (limited English proficient, economically disadvantaged, at-risk) and student achievement as measured by the TGI. The analyses found a very weak positive relationship between the TeacherInsight and …

Project SCORE: Life Skills for Future Success, is a structured, 20-lesson curriculum, designed to help students develop academic and life skills, as well as self-responsibility, commitment, optimism, respect, and excellence. The curriculum was presented during 36, 90-minute class periods over the fall semester of the students' freshmen year. The purpose of this study was to determine the effectiveness of Project SCORE at improving grades, learning strategies, self esteem and coping skills with freshmen students at an inner-city high school. In order to evaluate the program, students completed paper-pencil surveys at the beginning and end of the semester in which they were enrolled in the Project SCORE class. In addition, teachers completed evaluations on their perceptions of each student's peer relationships, classroom behavior, mood, and activity level. All teachers and students involved in the course were asked to complete an evaluation to determine their level of satisfaction with the course and areas in need of improvement. Lastly, information pertaining to grades, discipline and standardized test scores were used to determine the impact of SCORE. Participants were 333 9th grade students at a large 4A high school in Texas. Findings suggest that SCORE had a positive effect on coping resources, study skills …

Detective fiction highlights those qualities of masculinity that are most valuable to a contemporary culture. In mysteries a cultural context is more thoroughly revealed than in any other genre of literature. Through the crimes, an audience can understand not only the fears of a particular society but also the level of calumny that society assigns to a crime. As each generation has needed a particular set of qualities in its defense, so the detective has provided them. Through the detective's response to particular crimes, the reader can learn the delineation of forgivable and unforgivable acts. These detectives illustrate positive masculinity, proving that fiction has more uses than mere entertainment. In this paper, I trace four detectives, each from a different era. Sherlock Holmes lives to solve problems. His primary function is to solve a riddle. Lord Peter Wimsey takes on the moral question of why anyone should detect at all. His stories involve the difficulty of justifying putting oneself in the morally superior position of judge. The Mike Hammer stories treat the difficulty of dealing with criminals who use the law to protect themselves. They have perverted the protections of society, and Hammer must find a way to bring them …
