Analysis of Upstream Synoptic Conditions for Tropical Cyclones that Pass Near or Over Florida

During the course of the Atlantic hurricane season, numerous tropical cyclones (TCs) recurve around the Bermuda high. Where this recurvature occurs can have a large influence on societal impacts. Even with the advancement of numerical weather models and improved satellite capabilities, it is at times difficult to forecast exactly when a storm may recurve (e.g., Irma 2017). This study analyzes the upstream synoptic scale patterns for both landfalling and recurving TCs near the Florida coastline. The goal is to determine if there are specific synoptic conditions that can help predict whether a TC is more likely to make landfall in Florida or recurve to its east 1-7 days before the landfall or recurvature occurs. The data used in this study came from the National Hurricane Center best track and the ERA-Interim (ERA-I) reanalysis during the period 1979 to 2017. These files were sorted into three categories, with the following times noted: landfall in Florida; first motion vector with a greater northward component than a westward component; and first motion vector with an eastward component. The 500 hPa geopotential height fields were recorded every 24 h from 24 to 168 h prior to the times of landfall or recurvature. Using ERA-I data, composites were created for each category and each time prior to landfall or recurvature. Differences in the composite means were then calculated and tested for statistical significance using a Mann-Whitney U-test. The results indicate that there are differences in the 500 hPa height patterns of landfalling and recurving TCs. However, the locations where the 500 hPa heights are statistically different varies with time before landfall or recurvature

Injustice and the Victim\u27s Voice

A Review of The Faces of Injustice by Judith Shkla

Doctor of Philosophy

dissertationThis multisite case study sought to build a deeper understanding of community partner experiences with service-learning collaborations. The study examined how community partners involved with service-learning collaborations shape and evaluate these collaborations; what their motivations were when they started participating; why they choose, or choose not to, continue participating; and how service-learning supported their organization's identity. The study was comprised of 11 community partners, including seven nonprofit organizations, one government agency, and three Kindergarten-12th participants. It also included four staff from the three college service-learning centers represented in the study. Using a qualitative design, data were collected through a document review of community partner websites and annual reports, a focus group with college center staff, and 11 individual interviews with community partner representatives. Four major themes evolved from this study: expectations, investment, communication, and echelons of collaboration. Community partners and college center staff discussed how expectations, investment, and communication overlapped, yet contained separate characteristics that made each theme valuable in service-learning collaboration success. Community partners conceptualized varying echelons of collaborations that developed through relationships. Finally, community partners explained how service-learning assisted them with meeting operational needs that were central to their organization's identity. This study contributes to a growing field of literature about community partner experiences with service-learning. The findings from this study build on policies, practices, and research regarding service-learning and how the four major themes are vital in developing and sustaining collaborations

Debate on Bernard Yack's book Nationalism and the Moral Psychology of Community

Bernard Yack's Nationalism and the Moral Psychology of Community (2012) was the subject of the eighth in a long-running series of debates hosted by the Association for the Study of Ethnicity and Nationalism (ASEN) and the journal Nations and Nationalism in November of 2013. These debates bring together the authors of recent important works in the study of nationalism and ethnicity with appropriate scholars to explore the questions they have provoked. On this occasion Professor Yack was joined by Professor Chandran Kukathas and Professor David Miller. Chandran Kukathas holds a Chair in Political Theory in the Department of Government at the London School of Economics. His work addresses the history of liberal thought, contemporary liberal theory and issues of multiculturalism. He has examined the work of John Rawls and F. A. Hayek, and advances his own justification of liberalism and multiculturalism in The Liberal Archipelago: A Theory of Diversity and Freedom (Oxford) (Kukathas 2013), in which he argues that the looser image of the ‘archipelago’ is a more fitting metaphor for this form of society than ‘the body politic’ or the ‘ship of state’. David Miller is Professor of Political Theory, Politics and International Relations, at Nuffield College, Oxford. His writing on political theory has been particularly concerned with issues of justice and equality, and the themes of nationality, citizenship, territory and immigration. A distinguishing feature of his work is the use of evidence from the social sciences to inform debates in political philosophy. Recent work has been particularly concerned with global and social justice, and problems of collective responsibility. He recently published Justice for Earthlings: Essays in Political Philosophy (Cambridge UP) (Miller 2009)

Giving Way Event During a Combined Stepping and Crossover Cutting Task in an individual with Anterior Cruciate Ligament Deficiency

Study Design: Case study. Objective: To compare knee kinematics and moments of nongiving way trials to a giving way trial during a combined stepping and crossover cutting activity. Background: The knee kinematics and moments associated with giving way episodes sugge motor control strategies that lead to instability and recovery of stability during movement. Methods and Measures: A 27-year-old woman with anterior cruciate ligament deficiency reported giving way while performing a combined stepping and crossover cutting activity. P motion analysis system recorded motion of the pelvis, femur, tibia, and foot using 3 infrarec emitting diodes placed on each segment at 60 Hz. Force plate recordings at 300 Hz were combined with limb inertial properties and position data to estimate net knee joint moments. The stance time, foot progression angle, and cutting angle were also included to evaluate performance between trials. Results: Knee internal rotation during the giving way trial increased 3.2\u27 at 54% of stance relative to the nongiving way trials. Knee flexion during the giving way trial increased to 33.1 at 66% of stance, and the knee moment switched from a nominal flexor moment to 2 knee extensor moment at 64% of stance. The knee abductor moment and external rotation moment during the giving way trial deviated in early stance. Conclusions: The observed response to the giving way event suggests that increasing knee flexion may enhance knee stability for this subject. The transverse and frontal plane moments appear important in contributing to the giving way event. Further research that assists clinicians in understanding how interventions can impact control of movements in these planes is necessary

Validity and Comparisons of Tibiofemoral Angles and Translations using a New Femoral Tracking Device (FTD) during Walking

First, this study compares tibiofemoral motion during walking using a new femoral tracking device (FTD) and bone mounted markers in a single subject (n=1). The results suggest errors ofn=13). The results suggest similar tibiofemoral angles in the sagittal and frontal planes using the two methods (average root mean square (RMS) differences

Self-Reported Giving-Way Episode During a Stepping-Down Task: Case Report of a Subject With an ACL-Deficient Knee

Study Design: Case report. Objective: To describe the knee kinematics and moments of a giving-way trial of a subject with an anterior-cruciate-ligament– (ACL) deficient knee relative to his non–giving-way trials and to healthy subjects during a step-down task. Background: Episodes of giving way are believed to damage joint structures, therefore treatments aim to prevent giving-way episodes, yet few studies document giving-way events. Methods: The giving-way trial experienced by a 32-year-old male subject with ACL deficiency during a step-down task was compared to his non–giving-way trials (n = 5) and data from healthy subjects (n = 20). Position data collected at 60 Hz were combined with anthropometric data and ground reaction force data collected at 300 Hz to estimate knee displacement and 3-dimensional angles and net joint moments. Results: The knee joint displacement was higher during the giving-way trial: from 4% to 32% of stance, reaching 9.0 mm at 18% of stance as compared to 1.6 ± 0.7 mm for the non–giving-way trials. After 4% of stance, the knee flexion angle of the giving-way trial was 6.6° higher than the non–giving-way trials and was associated with a higher knee extension moment. The knee frontal plane moment was near neutral during early stance of the giving-way trial in contrast to the non-giving way and healthy subjects which demonstrated a knee abduction moment. Conclusions: The response of this subject to the giving-way event suggests that higher knee flexion angles may enhance knee stability and, in reaction to the giving-way event, that knee extension moment may increase

Relationship Between Static Mobility of the First Ray and First Ray, Midfoot, and Hindfoot Motion During Gait

The relationship between a static measure of dorsal first ray mobility and dynamic motion of the first ray, midfoot, and hindfoot during the stance phase of walking was investigated in healthy, asymptomatic subjects who represented the spectrum of static flexibility. Static first ray mobility of 15 subjects was measured by a load cell device and ranged from stiff (3.1 mm) to lax (8.0 mm). Using three-dimensional motion analysis, mean first ray dorsiflexion/eversion and mid-/hindfoot eversion peak motion, time-to-peak, and eversion excursion were evaluated. Subjects with greater static dorsal mobility of the first ray demonstrated significantly greater time-topeak hindfoot eversion and eversion excursion (p \u3c .01), and midfoot peak eversion and eversion excursion (p \u3c .01). No significant association was found between static first ray mobility and first ray motion during gait. This research provides evidence that the dynamic response of the foot may modulate the consequences of first ray mobility and that compensory strategies are most effective when static measures of dorsal mobility are most extreme
