This study proposes several decision-making tools utilizing optimization and machine learning frameworks to assess and improve the safety of the workplaces. The first chapter of this study presents a novel mathematical model to optimally locate a set of detectors to minimize the expected number of casualties in a given threat area. The problem is formulated as a nonlinear binary integer programming model and then solved as a linearized branch-and-bound algorithm. Several sensitivity analyses illustrate the model's robustness and draw key managerial insights. One of the prevailing threats in the last decades, Active Shooting (AS) violence, poses a serious threat to public safety. The second chapter proposes an innovative mathematical model which captures several essential features (e.g., the capacity of the facility and individual choices, heterogeneity of individual behavioral and choice sets, restriction on choice sets depending on the location of the shooter and facility orientation, and many others) which are essential for appropriately characterizing and analyzing the response strategy for civilians under an AS exposed environment. We demonstrate the applicability of the proposed model by implementing the effectiveness of the RUN.HIDE.FIGHT.® (RHF) program in an academic environment. Given most of the past incidents took place in built environments (e.g., educational and commercial buildings), there is an urgent need to methodologically assess the safety of the buildings under an active shooter situation. Finally, the third chapter aims to bridge this knowledge gap by developing a learning technique that can be used to model the behavior of the shooter and the trapped civilians in an active shooter incident. Understanding how the civilians responded to different simulated environments, a number of actions could have been undertaken to bolster the safety measures of a given facility. Finally, this study provides a customized decision-making tool that adopts a tailored maximum entropy inverse reinforcement learning algorithm and utilizes safety measurement metrics, such as the percentage of civilians who can hide/exit in/from the system, to assess a workplace's safety under an active shooter incident.

Target shooting in the United States has become an increasingly popular sport in the last century. In addition to the large quantity of lead pellets littering range grounds and surrounding land, considerable amounts of clay target fragments cover shooting range areas as well as adjoining habitats. Polycyclic aromatic hydrocarbons (PAHs) within the target, as well as lead pellets from shotguns pose multiple threats to a variety of wildlife. To determine the effects of clay target and lead pellet ingestion on wildlife, I conducted controlled experiments on Coturnix quail exposed to clay targets in the lab, and collected wild birds and mammals exposed to lead pellets at a shooting range. The first Coturnix study determined whether quail voluntarily consumed target fragments or limestone fragments. In both fall (F=29.2, P<0.01) and spring (F=6.45, P=0.02) experiments, I found that quail consistently selected limestone fragments, but almost completely rejected clay target fragments. In the second study, quail were force-fed varying amounts of target dust on a weekly basis to simulate sporadic exposure to clay target dust. In both summer (F=1.63, P=0.23) and winter (F=0.34, P=0.8) trials, male quail did not have significant weight loss. Female quail had insignificant weight losses in summer trials (F=1.63, P=0.23) but experienced weight gains in winter trials (F=3.53, P=0.04). In the third and final Coturnix study, varying amounts of target dust were incorporated into daily feed rations to simulate frequent exposure to clay target dust. Male quail experienced weight loss in both summer (F=16.13, P<0.01) and winter (F=8.47, P<0.01) trials. Female quail also suffered weight loss in both summer (F=15.62, P<0.01) and winter (F=17.50, P<0.01) trials. Weight loss likely resulted from inadequate nutrition as opposed to target poisoning. However, because there were no biochemical analyses performed to test for PAH presence, no definite conclusions can be made. The second study focused on lead contamination in Passeriformes, perching birds, and small mammals. Seventeen of 20 birds (85%) (Passerine spp) captured at the shooting range had elevated lead levels (F=5.21, P<0.028), when compared to birds (n=20) at the control site. Nine of 26 (35%) white-footed mice (Peromyscous leucopus), trapped at the shooting range had elevated liver (F=9.78, P=0.0029) and kidney (F=22.49, P<0.01) lead levels. These results indicate that Passerine species as well as Peromyscous species around shooting ranges inadvertently consume lead, either as lead pellets, mistaking them for grit or dietary items, or through environmental sources such as water, soil, and vegetation. / Master of Science

In this article post-shooting trauma is utilized as an arbitrary punctuation to indicate how police officers communicate their distress during this period of rapid transition in South Africa. It is argued that the medical model (with its attendant lineal causal explanations and descriptions) is inhibitively limited in describing what police officers are presently experiencing. The author motivates the advantages of perceiving and describing events from an ecosystemic perspective (which provides a contextual understanding and emphasizes relationships} . "Stress" is described as an aspect of the system as a whole and not singularly attributable to individuals alone. Among others new policing rules and roles, the turnover in personnel, and the rate of's'ocio-political changes are shown to contribute. It is argued that the Police, as society's guardians of "power" have become the "symptom bearers" for a society in the painful process of adapting to change.

Topic: Comparison of three-point shoot trials occurence and effectivity in the aspects of FIBA rule changes in 2010 as well as in a relation with placement of the teams in Czech Women's basketball league Aim: The main aim of the thesis is to find out whether the following four- year-period as a result of rule changes applying to an extension of three- point line was sufficient enough to be able to adapt from the frequency and success in three-point shoot of view in the highest Czech Women's basketball league in the basic part of the Championship in between the selected teams. We take into account eight surveyed seasons in this study, where straight after the period of first four seasons following one after another there was a rule of three-point line extention established. The statistics of three-point shoots in the four seasons mentioned above, which means after establishing the rule, are the main source of data used for this survey and was accomplished according to statistical results and comparing these results. The mail goal is to create statistical analysis that would show how great impact the three-point line extention had during following four seasons of the change, which means the adaptability process applied for three- point shooting within the teams placed in the first, fourth, seventh...

Title: The influence of kinematic factors on shooting velocity and accuracy in team handball. Goals: The main goal of this thesis is to find the influence of kinematic factors of throwing arm on shooting velocity and accuracy in team handball. Methods: The relationship between velocity and accuracy is based on practical measurement of group of team handballers. The measurement itself consists of three chosen types of shooting. We focused on movement and reciprocal position of reference points (ball, wrist, elbow and shoulder joint) and their influence on velocity and accuracy of hitting a target in goal. For measuring velocity is used a radar device Stalker. Measured values were elaborated in TEMA motion program which is appropriate for detail 3D analysis of throwing motion. Results: The results of this thesis demostrate the proximal-to-distal sequence in both types of throwing. An absolute velocities in this sequence were higher at Vmax shots than in accurate shots. There was found a significal difference between elbow extension angle of shots on upper and lower targets but exception. Higher elbow extension angle was found at Vmax shots than at accurate shots. This shows the influence of angle size on shooting velocity. A movement of the arm relative to vertical axis of a goal reflected an...

The Multiple Streams model developed by John Kingdon (1995) and Nikolaos Zahariadis (2007) provides a valuable framework for understanding the nature of policy change. This investigation draws extensively upon the Multiple Streams framework in order to understand the development of gun-control policy initiatives under President Barack Obama. The investigation uses a case-study approach with in-depth analysis of four different mass-shooting events that took place in the United States between 2009 and 2012. Reconstruction of the shooting events and detailed parsing of the Obama administration’s official responses to each incident, when viewed through the Multiple Streams lens, clearly explain why Obama’s aggressive policy initiative was so delayed in its emergence in spite of several shootings and the President’s clearly stated belief that gun-reform was a necessary step for the federal government. While the term “policy change” is broad and may encompass all sorts of governmental responsiveness, the term herein should be interpreted in the narrowest sense: exclusively encompassing legislative initiatives. Ultimately, the investigation concludes that numerous factors, but most prominently concerns about the timing and results of the 2010 Midterm and 2012 General Elections, prevented an aggressive pursuit of gun-reform prior to January 2013. The tragic shooting of 28 people in Newtown, Connecticut, then served as a prime focusing event for the President to aggressively engage a long-standing goal.

Title: Proposal on the optimal basketball training method within the physical education of children in older school age Author: Josef Růžička The study aims to find optimal theoretical model of basketball training method within the course of physical education at primary schools and general secondary schools. We focus on children in older school age. The objective is to make basketball training more effective as well as more familiar to teachers that are lacking more complex or personal experience with this sport. We use the method of experiment. First, the numbers of testing exercises to detect the level of general game skills of the children were defined. Then the model of teaching method consisting of ten setting-up (introductory) exercises was developed and implemented into a complete semestral plan. At the beginning of experiment, two groups of children were tested for their general game skills. Then our proposed model was applied onto these two groups. We aimed to develop model of teaching that would help to improve and develop basketball skills of children. At the end of experiment period were children's basketball game skills tested again to see what extend was our proposed model successful. The results proved that proposed method of teaching was appropriate, since both groups of children...
