Show moreThis study investigates the effects of self-regulated strategy development (Harris, Graham, (&) Mason, 2009) for cognitive strategy instruction in persuasive writing (POW+TREE) using a synchronous online learning environment for special education students. Participants are four adolescent students with learning disabilities (LD) with low achievement in writing. One undergraduate research assistant delivered instruction using a synchronous online platform (e.g., Adobe Connect) in conjunction with collaborative writing software (e.g., Google Docs word processing). A multiple probe across participants design was used to demonstrate a functional relationship between instruction and number of essay elements (EE). Number of correct minus incorrect word sequences (CIWS) was used as a secondary dependent measure. A non-experimental pre-post design was used to compare the mean performance of holistic writing quality scores and standard scores from the TOWL-3. All four participants gained EE and CIWS from baseline to treatment and demonstrated standard score changes from pre to post-test on the TOWL-3. Implications for writing instruction for students with LD using online learning environments are discussed.

AP U.S. History and AP World History examination scores of students who did and who did not participate in AP practice examination and AP beyond-school-day tutoring were analyzed to determine if the two instructional approaches to improving student examination performance were effective. Because the instructional approaches were implemented in one school within the school district of study, a purposive sample was used. Data collected included practice examination participation data, beyond-school-day tutoring attendance data, and AP U.S. History and AP World History examination scores for students enrolled in AP U.S. History and AP World History at the school of study (FHS) and the matched high school (MHS).

A video self-modeling (VSM) component was added to the SRSD method. A multiple probe across participants, single-subject design was used to determine the effectiveness of the SRSD instructional strategy, (POW + TREE), in combination with video self-modeling. Data from various components of writing, including essay elements, length of responses, time spent writing, and overall writing quality, were collected and assessed to determine the effectiveness of the intervention. All students who received the intervention improved their overall writing performance on opinion essays as measured by the number of opinion essay elements, including topic sentence, reasons, examples, and ending. During the maintenance phase of the intervention, students who received a VSM booster session increased their total number of opinion essay elements back to mastery levels.

Show moreTeaching conversational strategies has been effective for a wide array of clients with acquired neurologic disorders and their caregivers. Research indicates positive results for Supported Conversation in adults with Aphasia (SCA) secondary to stroke. Applying this method to work with caregivers of persons with memory impairment could prove to be a valid intervention tool. This investigation will examine the applicability of SCA with persons with memory impairment and their familial caregivers. This pilot study is intended to create a conversation regarding SCA and its implementation with persons with memory impairment who still live in the community with their caregivers. Analysis between the pre-training and post-training scores showed a trend to wards significance for Time (F(1, 9) = 0.064), no significance for Measure (F(3, 9) = 0.558), and no significance for the interaction of Time*Measure (F(3, 9) = 0.276). The effect size for Time was 0.732, for Measure was 0.494 and for Time*Measure was 0.956.

Title: MARKET FORESIGHT CAPABILITY: DETERMINANTS AND NEW PRODUCT OUTCOMES.

Show moreTo achieve and maintain a superior competitive position, firms must develop market sensing capability—the ability to sense events and trends in markets ahead of competitors (Day 1994a). According to Day, in firms with superior market sensing capability, “the processes for gathering, interpreting, and using market information are more systematic, thoughtful, and anticipatory than in other firms” [emphasis added]. Although Day asserted that market orientation captures the essence of a market sensing capability, researchers have suggested that market orientation, by itself, does not provide the requisite ability to develop competitive advantage because of its focus on detecting rather than anticipating market trends. While prior research, most notably pertaining to market orientation, has addressed the detection of current market trends, a gap in our knowledge remains regarding the ability to anticipate future market conditions. This research seeks to address this lacuna by exploring a firm’s market foresight capability, defined as the organizational capability that allows the firm to anticipate emerging shifts in the market before they are evident to competitors. Organizations possessing superior market foresight capability derive a multitude of benefits from having greater insight into future market conditions. These benefits include the ability to determine which future market trends warrant further exploration and exploitation, the identification of critical resources that will be needed in the future, and-of primary interest in this dissertation—the ability to develop new products that meet customer needs in the future. This research seeks to better inform managers as to the organizational characteristics that enhance the firm’s ability to anticipate future markets by developing and testing a model of the antecedents and new product outcomes of a firm’s market foresight capability. The constructs selected as determinants of market foresight capability are supported by dynamic capability theory, which focuses on the organization’s information processes, learning culture, and coordination/integration influences that elevate lower-level capabilities of individuals and teams to an organization-level or dynamic capability. The organizational information processes that are hypothesized to positively impact market foresight capability include active scanning, market experimentation, and lead user collaboration. The impact of information processes on market foresight capability is contingent on an organization’s learning culture (future orientation and learning orientation) and interdepartmental connectedness, which influence the coordination and integration of information between organizational actors. A firm’s potential for long-term competitive advantage lies in using the insights resulting from its market foresight capability to create advantageous resource configurations. To create valuable resource configurations, the firm with superior market foresight capability must capitalize on its ability to anticipate change through the development of new product and service offerings that better serve the needs of customers. It is hypothesized that superior market foresight capability results in heightened new product creativity, faster speed to market, and better market-entry timing. These new product outcomes of market foresight capability are further hypothesized to lead to superior new product financial performance. Of course, firms cannot realize the hypothesized new product benefits unless they are able to capitalize on market opportunities. Therefore, the relationships between market foresight capability and new product outcomes are hypothesized to be contingent on organizational inertia.

Show moreHypertext and hyperlinks are present on almost every web site or electronic document. As integral components of visual rhetoric, they are foundational to any discussion of technology and literacy. This inquiry is designed to explore first-year composition students' advances in technological literacy, specifically hypertext reading and research strategies. To accomplish this, a hypertext-reading project was designed to investigate the ways in which first-year composition students assimilate and employ hypertext information as a source from which they must extract information to use in the development of an argument. A program, designed and written specifically for this project, presented research participants, 76 students enrolled in second semester first-year composition, the components of hypertext reading as an online reading and research activity. Participants first completed a technology survey designed to reveal each participant's prior experience and self-perceived expertise with current technology, after which they completed a two-part exercise consisting of a hypertext reading assignment and a post-reading questionnaire. Participants were instructed to use their reading to inform and develop a thesis for an argument. The article selected for this study was "Illegal Immigration," accessed by navigating to http://en.wikipedia.org/wiki/Illegal_immigration. The article discusses a current controversial national concern, illegal immigration. While the use of Wikipedia, an online user-edited encyclopedia, often raises credibility concerns, the site in general offers excellent examples of hypertext reading that include textual as well as graphic links. In the analysis, it is revealed that while the study group rated themselves highly proficient users of Internet search engines, email, social networking, and word processing applications, the majority initially did not recognize a relationship between the actions they take as users of those applications and hyperlinks or hypertext. Post-reading responses revealed that the majority of the group read the article from top to bottom with few to no diversions. Furthermore, while most did recognize the hyperlinks as information portals, they made conscious decisions to not access the links for a variety of stated and implied reasons. This research involved a relatively small student sample that defines the limited scope of the findings; however, the data suggests attitudes and expectations of this group that may reflect student populations with similar or shared demographics. These data are used to inform potential pedagogical application suggestions, including the usefulness of technological proficiency assessments and research using technology within the classroom as well as in external assignments.

Show moreCrew race strategy is typically formulated by coaches based on rowing tradition and years of experience. However, coaching strategies are not generally supported by empirical evidence and decision-support models. Previous models of crew race strategy have been constrained by the sparse information published on crew race performance (quarterly 500-meter splits). Empirical research has merely summarized which quarterly splits averaged the fastest and slowest relative to the other splits and relative to the average speed of the other competitors. Video records of crew race world championships provide a rich source of data for those capable and patient enough to mine this level of detail. This dissertation is based on a precise frame-by-frame video analysis of five world championship rowing finals. With six competing crews per race, a database of 75 race-pair duels was compiled that summarizes race positioning, competitive drives, and relative stroke rates at 10-meter intervals recorded with photo-finish precision (30 frames per second). The drive-based research pioneered in this dissertation makes several contributions to understanding the dynamics of crew race strategy and performance: 1) An 8-factor conceptual model of crew race performance. 2) A generic drive model that decomposes how pairs of crews duel in a race. 3) Graphical summaries of the rates and locations of successful and unsuccessful drives. 4) Contour lines of the margins that winning crews hold over the course of the race. 5) Trend lines for what constitutes a probabilistically decisive lead as a function of position along the course, seconds behind the leader, and whether the trailing crew is driving. This research defines a new drive-based vocabulary for evaluating crew race performance for use by coaches, competitors and race analysts. The research graphically illustrates situational parameters helpful in formulating race strategy and guiding real-time decision-making by competitors. This research also lays the foundation for future industrial engineering decision-support models and associated parameters as applied to race strategy and tactics.

Show moreThis study examined the effects of implementing Web-enabled technology systems on the functional role of the community college registrar. The focus on systems implementation included in-house, outsourced, consortia, or combination of implementation strategies. A quantitative and qualitative approach included several interviews and a mailed survey questionnaire. The researcher developed the instrument from human resources position description forms, an adapted administrative Q-sort technique, and a role conflict and ambiguity perception questionnaire. The study targeted the members of the American Association of Collegiate Registrars and Admissions Officers. The research findings indicated that some aspects of perceived role, role conflict (harmony), and ambiguity (clarity) were different for registrars whose colleges used in-house, outsourced, consortium, or a combination of implementation strategies, and for certain background characteristics. For example, the study identified different levels of involvement for some duties and some differences in collaboration among divisions and departments within institutions and with other organizations. Suggested uses of the research results include professional development programming for more efficient technology implementation. The research instrument could be adapted to study functional role of other job positions, implementation projects, and administrative strategies.

Show moreRelational bullying, although covert in nature and difficult for adults to notice and identify, is becoming increasingly prevalent among young children and teens. The success of bibliotherapy as preventative and intervention practices for bullying shows that portrayals of relational bullying in quality children's literature would be effective in reducing and preventing it. However, relational bullying is rarely portrayed in children's literature. My goal was to find quality children's realistic fiction literature that portrays relational bullying in Newbery award-winning books, and to bring them to the attention of teachers. After creating a table to determine what types of bullying, if any, were portrayed in the 21 Newbery Medal and Honor realistic fiction children's literature (1996-2016), the books were read in their totality, and analyzed for any portrayals of relational bullying, including the experience of bullying from the eyes of the bully, victim, and bystander. The bullying portrayed in the literature was described, as well as the characteristics of the bully and victim. Only 10 out of the 21 books read contained portrayals of bullying in the plot. Using this information, future research will include creating a website for teachers, other educational professionals, and parents, to help bring quality children's literature portrayals of relational bullying to their attention. The hope is that teachers will begin to use the findings of this study as a resource with their students, to prevent or address relational bullying in their classrooms, and to recommend it to school psychologists, counselors, and parents, as needed.

Show moreThe work presented in this thesis deals with the application of optimization tools to the design of solid rocket motor grains per internal ballistic requirements. Research concentrated on the development of an optimization strategy capable of efficiently and consistently optimizing virtually an unlimited range of radial burning solid rocket motor grain geometries. Optimization tools were applied to the design process of solid rocket motor grains through an optimization framework developed to interface optimization tools with the solid rocket motor design system. This was done within a programming architecture common to the grain design system, AML. This commonality in conjunction with the object-oriented dependency-tracking features of this programming architecture were used to reduce the computational time of the design optimization process. The optimization strategy developed for optimizing solid rocket motor grain geometries was called the internal ballistic optimization strategy. This strategy consists of a three stage optimization process; approximation, global optimization, and highfidelity optimization, and optimization methodologies employed include DOE, genetic algorithms, and the BFGS first-order gradient-based algorithm. This strategy was successfully applied to the design of three solid rocket motor grains of varying complexity. The contributions of this work was the development and application of an optimization strategy to the design process of solid rocket motor grains per internal ballistic requirements.

Show moreThe explicit teaching of reading comprehension strategies has been proposed as a means to better prepare secondary school-aged students for today's information-dense, fast-paced, fast-changing global society, and to improve the academic performance of struggling adolescent readers. This proposition of a direct and positive impact of reading comprehension strategies on reading achievement for all students has not been investigated with English language learners (ELLs) who, by definition, do not possess the same level of English language skills as their native-English speaking peers. This mixed-method study investigated linguistic, cognitive, as well as affective factors that impact adolescent ELLs' performance on a standardized state reading achievement test. The quantitative portion examined the relative contributions of second language proficiency and reading comprehension strategies to a prediction model of reading achievement in 110 ninth and tenth grade ELLs. The qualitative portion of the study involved individual interviews and was aimed at deepening the understanding of ELLs' use of strategies during the standardized reading test, while also investigating affective factors that may impact their performance on this measure of academic achievement. Quantitative findings include two statistically significant prediction models of reading achievement with reading comprehension strategies and English language proficiency as predictor variables. However, only language proficiency made a significant unique contribution to the prediction variable. Qualitative findings suggest that the participants had relatively little metacognitive awareness of their comprehension during the standardized test, had overestimated their use of reading strategies as reported on a 30-item strategy survey instrument, had concentrated on sentence-level comprehension due to unknown vocabulary, and may have been hindered by testing anxiety in being able to wholly concentrate on the task. Recommendations made for the instruction of comprehension strategies consist of the raising of metacognitive awareness through the explicit modeling of the thought processes involved in reading comprehension, including determining the meaning of unknown words.

Show moreThe international political landscape of the 21st century is strewn with terrorist groups that choose to act violently in order for their political messages to be heard. Around the world groups have been formed to defend their ideologies and fulfill their political agendas through acts of terrorism. The Baader-Meinhof Gang [also known as the Red Army Faction], the Weather Underground, the Liberation Tigers of Tamil Eelam, Hezbollah, the Revolutionary Armed Forces of Colombia, HAMAS, and the Irish Republican Army have existed for many decades. They represent only a small handful of terrorist groups that have kidnapped, targeted public institutions with bombs, and employed suicide terrorism. More often than not innocent civilians become involved in the carnage of an act of terrorism when they are caught off guard as unassuming bystanders. On September 11th, 2001 both the American public and US government officials bore the weight of that horrific day. Since 9-11, Americans were robbed of their sense of safety, and the American dream of tranquility was shattered. A general unease spread from the wreckage of the World Trade Centers, and with the passing of time a keen sense of awareness about terrorism took its place. The events of 9/11 have made US citizens fully cognizant that there are many actors actively plotting the destruction of the US. Now, eight years later, Americans live with the daily realization that such a heinous act could happen again, in some other unimaginable form. For the US government, the past eight years have been marked with as many successes as failures. The consequences of the inability of the US intelligence community to foresee the international plot unfolding, within and outside of the homeland, resulted in a major reorganization within the US government. The US Department of Homeland Security (DHS) was established on November 25, 2002, and was created solely to address US vulnerabilities highlighted by the actions of nineteen al-Qaeda suicide terrorists. The DHS' main responsibility is to improve communication and information sharing among various intelligence-gathering agencies, so another attempt to plan an attack like 9/11 on US soil would be foiled before it materialized. The US government would no longer be noncommittal in the face of terrorism, as it had before 9/11. Clear messages to terrorists were sent on October 7th, 2001, through the US invasion of Afghanistan, and subsequently on March 20th, 2003 through the US invasion of Iraq. Thus, the US' stance on the War on Terrorism was effectively and clearly communicated to al-Qaeda and throughout the rest of the world. The US might once have been labeled a paper tiger, but hitting the US at the core of their financial and military symbols struck a nerve. The terrorist attacks of 2001 taught the US government a vital lesson, but the military campaigns of Afghanistan and Iraq would demonstrate that the US had even more to learn about the newest military tactics and techniques employed by the enemy, and how these tactics impacted on US military operations, strategies, and policies.

Show moreThe Medicaid Home and Community Based Services Waiver (HCBS) funds services for people with developmental disabilities in community based group homes. The purpose of the Medicaid HCBS Waiver is to: (1) support alternatives to institutions, (2) promote independence, (3) maximize functioning, and (4) support community integration. Direct care staff members have primary, day to day contact with people with developmental disabilities living in group home settings. Residential agencies for people with developmental disabilities have the responsibility to train direct care staff in the use of effective teaching strategies in order to realize the purpose of the Medicaid HCBS waiver. Direct care staff's knowledge of effective teaching strategies will afford people with mental retardation an opportunity for greater independence and help them achieve their maximum potential within the community. This study set out to evaluate what factors were related to direct care staff members' knowledge of effective teaching strategies. The factors investigated include agencies use of evidence based staff training practices, feedback as a performance management strategy, and Certified Behavior Analysts involvement with the training and support of direct care staff. A random sample of 294 direct care staff members who work in 55 different group homes throughout the State of Florida participated in the study. Direct care staff members' average score on the knowledge of effective teaching strategies quiz was 23.31 out of 50 questions. The maximum score achieved was 43. These findings indicated that the direct care staff members generally did not demonstrate knowledge of effective teaching strategies. The findings of this investigation demonstrated a statistically significant positive relationship between direct care staff members who received empirically derived staff training and knowledge of effective teaching strategies. Additionally, the investigation found a statistically significant positive relationship between the behavior analyst involvement and direct care staff members' knowledge about how to teach. The investigation failed to identify a statistically significant relationship between performance feedback and knowledge about how to teach. This research is important to policy formulation as it relates to the efficient and effective delivery of supports for people with developmental disabilities.

Show moreThe purpose of this study was to investigate the differences between general and special educators regarding the implementation of research-based strategies that target the needs of students with LD in mathematics, as well as general and special educators' perceptions of their preparedness to use instructional strategies in mathematics. A sample of general and special educators who taught mathematics to students with learning disabilities (LD) at the middle school level responded to an online survey. The survey examined teacher self-reported classroom use of instructional practices specifically aligned with NCTM standards, direct instruction, graduated instruction, grouping practices, and self-monitoring. Additionally, educators responded to perceptions of their preparedness to use the aforementioned instructional practices. From the survey results, several strategies exhibited statistically significant differences between general and special educators. Special educators showed significantly greater use of two instructional strategies, as well as significantly greater perceptions of preparedness to use two instructional strategies. Overall, significantly more special educators reported using the research-based strategies aligned with all instructional practices. Additional results, limitations, implications for practice, and recommendations for future research are provided.

Show moreThis dissertation investigated the development, implementation, and evaluation of a management methodology founded on the alignment among the strategy, performance, and customer to bring value to any organization. A case study/action research in a service organization, called Institution "Z," provided the opportunity to assess the effects of the proposed Six Sigma Scorecard (SSS) methodology in the productivity indicators (measured by cycle time, line capacity, and number of errors). The Case study/action research was conducted in three phases: Model and Concepts Design, Data Collection, and Findings. During the research, validity was pursued by using triangulation and theory to help maintain the case under research control. The observation of the SSS methodology in a real organization allowed the researcher to describe the merging process between Balanced Scorecard and Six Sigma methodology and their relationships to each other. The SSS methodology allowed identification of improvement projects that contribute to organizational strategy, implementation of strategies and provide feedback to the top level of management establishing alignment at three organizational levels – corporate, business, and functional. The results of the implementation of the SSS methodology in Institution Z showed a 40% improvement of the cycle time of the auto credit process, a 500% increase in the capacity of the process, and 65% decrease in the number of non-added value activities. During the same period of time, the BSC indicators showed a positive impact, specifically one financial indicator known as Level of Intermediation or GIC grew from 30% to 42% as it was expected by the end of the SSS implementation. The demonstration of the SSS framework in a Case study justifies the need for a combined methodology that aligns strategy, performance improvement and organizational outputs in a feedback loop. More research in this area is needed, especially investigations that include assessment studies where different management approaches are used alone and combined with strategic tools, and investigations that measure the relationship between level of coherence in the three merging points of the SSS and the results reached at the performance of the organization.

Show moreAs public administration evolved to encompass a strong focus on supporting safe growth and development for communities, the role and responsibilities of government became increasingly complex with aspects of emergency management becoming quintessential. The ability to assess resilience plays a strong role in understanding the capability of a community to face a range of threats. Additionally, issues with communication uncovered the need to understand how administrators collect, disseminate, and adapt critical information through understanding crisis type and local community needs. This dissertation discusses the connection between public administration and emergency management, the evolution of crisis communication and strategies, resilience and its measurement, along with Situational Crisis Communication Theory. This study conducted an online-survey of county, and county-equivalent, emergency managers across the United States. Results of Structural Equation Modeling included statistically significant relationships between Crisis Type and Local Community Needs on Crisis Communication Strategies as well as between strategies onto Community Resilience. Comparative analysis with the Baseline Resilience Indicators for Communities showed stark contrast in perceived resilience capacity. Follow-up, semi-structured interviews were conducted with voluntary respondents and analyzed via axial, deductive coding. Comparing quantitative and qualitative analysis highlighted the importance of county characteristics, critical relationships, overcoming obstacles, need for learning and adaptation, and importance of communication.

Show moreWe examined the potential to improve the movement of freight using Truck PlatooningLane strategies on limited access highways in the State of Florida. In the First part of thisresearch, we investigated the potential benefits from dedicating one lane from existinglanes for autonomous trucks only. In this regard, a general framework tool was developedto evaluate and compare different measurements (e.g., travel tim and emissions) to betterassist decision makers to determine the most effective freight transportation strategy.Additionally, the travel time, level of service and emissions on Florida Strategic IntermodalSystem (SIS) were systematically analyzed using a VISSIM and MOVES simulation todetermine if it can be improved. For the scenarios simulated in this investigation, the inputincluded different patterns with a variety of peak hour volumes, truck percentages, speeds,and number of lanes. Additionally, the various total values of the resultant travel time,emissions and level of service for each SIS corridor were determined and calculated usinga General Linear Model and then tabulated to reveal input patterns. The results showed thata truck platooning lane can significantly reduce the travel time and emissions of trucks. Inthe second part, we proposed using a The Analytic Hierarchy Process (AHP) method toevaluate the potential benefits of building a new lane for autonomous trucks. The AHPmethod was developed to include all possible measurements that can assist decision makersto select the best autonomous truck policy. The results of the AHP model showed that thesafety criterion was significantly the most influential perspective per experts' opinions. Theresults showed that experts were more concerned about safety and environmentalconsiderations than the initial cost associated with building a new lane.

Show moreFor a recently constructed disease detection agricultural ground robot, the segregation of unhealthy leaves fromstrawberry plants is a major task of the robot's manipulation subsystem in field operations. In this dissertation, the motion planning of a custom-designedpicking mechanism in the ground robot's subsystem is studied in two sections. First, a set of analytical, suboptimal semi-analyticaland numerical algorithms are studied to solve the inverse kinematics problem of the handling mechanism in firmcircumstances. These premeditated approaches are built on the computation of the joint variables by an identified 3Dposition data of the target leaf only. The outcomes of the three solution algorithms are evaluated in terms of the performanceindexes of energy change and the CPU time cost. The resultant postures of the mechanism for different target pointlocations are observed both in simulations and the hardware experiments with each IK solution. Secondly, after the manipulation task of the mechanism via the proposed inverse kinematicalgorithms is performed, some compensation may be needed due to the sudden and unpredicted deviation of the targetposition under field conditions.For the purpose of finding optimal joint values under certain constraints, a trajectory optimization problem in image-based visual servoing method via the camera-in-handconfiguration is initiated when the end-effector is in the close proximity of the target leaf. In this part of the study, a bio-inspired trajectory optimization problem in image-basedvisual servoing method is constructed based on the mathematical model derived from the prey-predatorrelationships in nature. In this biological phenomenon, the predator constructs its path in a certain subspace whilecatching the prey. When this motion strategy is applied to trajectory optimization problems, it causes a significantreduce in the computation cost since it finds the optimum solution in a certain manifold. The performance of the introducedbio-inspired trajectory optimization in visual servoing is validated with the hardware experiments both in laboratory settings and in fieldconditions.
