Collaborative Risk Method For Information Security Management Practices: A Case Context Within Turkey, Bilge Karabacak, Sevgi Ozkan

All Faculty and Staff Scholarship

In this case study, a collaborative risk method for information security management has been analyzed considering the common problems encountered during the implementation of ISO standards in eight Turkish public organizations. This proposed risk method has been applied within different public organizations and it has been demonstrated to be effective and problem-free. The fundamental issue is that there is no legislation that regulates the information security liabilities of the public organizations in Turkey. The findings and lessons learned presented in this case provide useful insights for practitioners when implementing information security management projects in other international public sector organizations.

Adsorption Of Lead (Ii) By A Non-Living Algal Biomass., Mudher A. Hussein

Student Works (2010-2019)

Conventional techniques for removing dissolved heavy metals are only practical and cost-effective when applied to high strength wastes with heavy metal ion concentrations greater than 100 ppm. The possibility of using a non-living algal biomass to solve this problem was studied. Lead(II) was used in this study because it has been reported to cause several disorders in human. The non-living algal biomass was obtained from the filamentous green alga Spirogyra neglecta. The effects of initial concentration and contact time, pH, and temperature on the adsorption of lead(II) by the non-living algal biomass were studied. The equilibrium isotherms and kinetics were …

Effect Of Cu Addition On The Conductivity Of Xcui-(1-X)Agi,(0.1 _ X _ 0.4) Solid Solutions., Chu Lee Peng

Student Works (2010-2019)

Silver Iodide (AgI) based superionic conductors continue to be investigated for their intriguing structure phase transformation and complex but useful ion dynamics. However, unlike the others alkali iodides, AgI does not easily admit impurities in its tetrabonded zincblende structure. Introduction of copper (I) iodide (CuI) into AgI lattice was expected to initiate and stabilize changes in structure of the cation sublattice which controls the phase stability and phase transition behavior. In the present work, silver rich xCuI-(1-x)AgI (0.1 ' x ' 0.4) have been prepared by sintering method. The mixtures were ground and pelletized before subjected to sintering temperature at …

On Osgood's Criterion For Classical Wave Equations And Nonlinear Shallow Water Wave Equations, Timothy Smith, Greg Spradlin

Assessment Of Teachers’ Core Beliefs Related To Key Features Of Response To Intervention, Jacqlyn Tumolo Zarabba

PCOM Psychology Dissertations

The requirements of the No Child Left Behind Act require that schools are accountable for the outcomes of all students. Response to Intervention (RtI) provides a framework to assist in the actualization of this goal. This educational reform effort requires dramatically different functioning on the part of all school personnel, particularly teachers. In order for this model to be successful, researchers must acknowledge the primacy of teacher level factors, such as beliefs and attitudes related to core components of RtI. The purpose of this study was to examine the core beliefs of elementary-level teachers relative to foundational components of RtI, …

Temporal Scales For Transport Patterns In The Gulf Of Finland, Bert Viikmae, Tarmo Soomere, Mikk Viidebaum, Mihhail Berezovski

Publications

The basic time scales for current-induced net transport of surface water and associated time scales of reaching the nearshore in the Gulf of Finland, the Baltic Sea, are analysed based on Lagrangian trajectories of water particles reconstructed from three-dimensional velocity fields by the Rossby Centre circulation model for 1987–1991. The number of particles reaching the nearshore exhibits substantial temporal variability whereas the rate of leaving the gulf is almost steady. It is recommended to use an about 3 grid cells wide nearshore area as a substitute to the coastal zone and about 10–15 day long trajectories for calculations of the …

These numerical experiments allowed us to analyse the advantages and weaknesses of the microstructure model.

A Needs Assessment For Continuing Education Of Federal Wildlife Damage Management Professionals, Jessica L. Tegt, Phillip D. Jones, Ben C. West

Human–Wildlife Interactions

The complexity of wildlife damage management requires professionals to continually acquire new knowledge and skills that can be obtained through continuing education. Current literature suggests that wildlife damage management personnel are not receiving adequate training either as new professionals entering the fi eld or through continuing training as existing professionals. To better understand the continuing education needs of wildlife damage managers, we conducted a nationwide, on-line needs assessment survey for supervisory personnel of the U.S. Department of Agriculture, Animal and Plant Health Inspection Service, Wildlife Services program (hereafter, WS). The goal of our survey was to identify gaps in continuing …

A Scalable Method For Solving High-Dimensional Continuous Pomdps Using Local Approximation, Tom Erez, William D. Smart

All Computer Science and Engineering Research

Partially-Observable Markov Decision Processes (POMDPs) are typically solved by finding an approximate global solution to a corresponding belief-MDP. In this paper, we offer a new planning algorithm for POMDPs with continuous state, action and observation spaces. Since such domains have an inherent notion of locality, we can find an approximate solution using local optimization methods. We parameterize the belief distribution as a Gaussian mixture, and use the Extended Kalman Filter (EKF) to approximate the belief update. Since the EKF is a first-order filter, we can marginalize over the observations analytically. By using feedback control and state estimation during policy execution, …

Against All Probabilities: A Modeling Paradigm For Streaming Applications That Goes Against Common Notions, Rahav Dor

All Computer Science and Engineering Research

Hardware and software design requires the right portion of skills and mental faculties. The design of a good system is an exercise in rational thinking, engineering, and art. The design process is further complicated when we aspire to build systems that exploit parallelism or are targeted to be deployed on architecturally diverse computing devices, FPGAs or GPUs to name just a few. The need to develop systems that can take advantage of computing devices beyond general purpose CPUs is real. There are several application domains and research efforts that will simply not be able to adequately perform or yield answers …

Optimal Design-Space Exploration Of Streaming Applications, Shobana Padmanabhan, Yixin Chen, Roger D. Chamberlain

All Computer Science and Engineering Research

Many embedded and scientific applications are frequently pipelined asynchronously and deployed on architecturally diverse systems to meet performance requirements and resource constraints. We call such pipelined applications streaming applications. Typically, there are several design parameters in the algorithms and architectures used that, when customized, impact the tradeoff between different metrics of application performance as well as resource utilization. Automatic exploration of this design space is the goal of this research. When using architecturally diverse systems to accelerate streaming applications, the design search space is often complex. We present a global optimization framework comprising a novel domain-specific variation of branch-and-bound that …

Social Support As Moderator Of Job-Specific Or Generic Stressors With Strains, Kaci Deeana Mabe

Master's Theses

Two studies examining the relationship between job-specific stressors and strains versus the relationship between generic stressors with strain, as well as the moderating role of social support (from coworkers and administrators), are presented. Eighteen primary school teachers from a private Jewish day school (Study 1) and 242 teachers from an Arizona school district (Study 2) completed self-administered surveys. Results indicated that job-specific (vs. generic) stressors had a stronger positive relationship with strains, but social support was a better moderator for the relationship between generic stressors and strain. As hypothesized, administrator support had a reverse-buffering effect on the stressor-strain relationship in …

Family Of Circulant Graphs And Its Expander Properties, Vinh Kha Nguyen Tran Nguyen

Master's Theses

In this thesis, we apply spectral graph theory to show the non-existence of an

expander family within the class of circulant graphs. Using the adjacency matrix and its properties, we prove Cheeger's inequalities and determine when the equalities hold. In order to apply Cheeger's inequalities, we compute the spectrum of a general circulant graph and approximate its second largest eigenvalue. Finally, we show that circulant graphs do not contain an expander family.

Oscillatory Flows Induced By Microorganisms Swimming In Two Dimensions, J. S. Guasto, Karl A. Johnson, Jerry P. Gollub

Biology Faculty Scholarship

We present the first time-resolved measurements of the oscillatory velocity field induced by swimming unicellular microorganisms. Confinement of the green alga C. reinhardtii in stabilized thin liquid films allows simultaneous tracking of cells and tracer particles. The measured velocity field reveals complex time-dependent flow structures, and scales inversely with distance. The instantaneous mechanical power generated by the cells is measured from the velocity fields and peaks at 15 fW. The dissipation per cycle is more than 4 times what steady swimming would require. A pdf of this published paper has been uploaded elsewhere on this page. Guasto was a post-doctoral …

Heat Stress Evaluation Of Protective Clothing Ensembles, Amanda Lee Pease

USF Tampa Graduate Theses and Dissertations

Clothing directly affects the level of heat stress exposure. Useful measures to express the thermal characteristics are WBGT (wet bulb globe temperature) clothing adjustment factor (CAF) or apparent total evaporative resistance (R_e,T,_a). The CAF is assigned through laboratory wear trials following a heat stress protocol in which the air temperature and humidity are progressively increased until the participant clearly loses the ability to maintain thermal equilibrium. The critical condition is the point of thermal transition and from these conditions both the CAF and Re,T,a are computed. The first objective of this study is to compare the …

A Mixed-Methods Research Study Comparing Observations During Integrated Curriculum Lessons With Traditional Single-Subject Lessons For Primary-Age Students, Ksenia Sergeevna Zhbanova

Graduate Research Papers

This study examined teacher talk and actions under two conditions: ( 1) subject-integrated lessons of an integrated curriculum unit on African culture ( experimental condition); and (2) single subject-focused lessons of a traditional separate subject curriculum on mathematics time and money measurement (control condition). The study sought to define and compare characteristics of both curriculum approaches. Although the study was primarily qualitative with observations being recorded by the researcher that were subsequently sorted into categories through a constant comparison method, counts of frequency of observations in categories were recorded, resulting in a mixed-methods design.

The observations were collected in two …

Spatial Distribution Of Soda Straws Growth Rates Of The Coufin Cave (Vercors, France), Yves Perrette, Stéphane Jaillet

International Journal of Speleology

The Choranche Cave system (Vercors, France) is an excellent locality for measuring the growth rates of large numbers soda straws. This is especially the case for the Coufin Cave, as enlargement of the cave entrance in 1875 led to a change in stalactite color from brown to white, thus providing a reliable chronomarker. The date of this brown-to-white calcite transition has been confirmed by lamina counting. We measured and georeferenced the growth-lengths of 306 soda straws in a 1m² area of the roof of the Coufin Cave entrance chamber. Because of the very slow and sometimes inexistent water feeding …

Do Karst Rivers “Deserve” Their Own Biotic Index? A Ten Years Study On Macrozoobenthos In Croatia, Biljana Rađa, Sanja Puljas

International Journal of Speleology

In this study we present the results of a ten year survey of the aquatic macroinvertebrate fauna along four karst rivers: Jadro, Žrnovnica, Grab and Ruda, all of them situated in the Middle Dalmatia region of Croatia, in an attempt to construct the Iliric Biotic Index, which will be more applicable for the water quality analysis than the most frequently applied biotic index in Croatia, the Italian Modification of Extended Biotic Index. The rivers geologically belong to the Dinaric karst, unique geological phenomena in Europe. Benthic macroinvertebrates were collected along each river at 15 sites by standard methods of sampling …

Hyperbolic Systems Modeling Currency Hoarding, Elena Quercioli, Jeffrey Rauch

School of Economics and Finance Faculty Publications

We introduce and analyse linear systems of hyperbolic partial differential equations that model the replacement and hoarding of currency. The goal is to deduce the hoarding behavior from observations of circulating bills. The large time asymptotics of the models is identified in all cases. The mathematical analysis is novel, partly because of nonstandard boundary conditions. To identify parameters we suggest the measurement of the age histogram of notes, the rate of growth, and the retard in wear of notes due to hoarding. In our models that suffices to identify all but one quantity.

Differences In The Mechanism Of Collagen Lattice Contraction By Myofibroblasts And Smooth Muscle Cells, J. C. Dallon, H P. Ehrlich

Faculty Publications

Both rat derived vascular smooth muscle cells (SMC) and human myofibroblasts contain $\alpha$ smooth muscle actin (SMA), but they utilize different mechanisms to contract populated collagen lattices (PCLs). The difference is in how the cells generate the force that contracts the lattices. Human dermal fibroblasts transform into myofibroblasts, expressing $\alpha$-SMA within stress fibers, when cultured in lattices that remain attached to the surface of a tissue culture dish. When attached lattices are populated with rat derived vascular SMC, the cells retain their vascular SMC phenotype. Comparing the contraction of attached PCLs when they are released from the culture dish on …
