Full textAbstract:
The project has involved the development of two kinds of shooting targets in partnership with Marcus Bergkvist and Christopher Åkerblom. The project from the client was divided into two parts. This thesis discusses solutions for hands-on transport, development of tripods and an overall design. The second thesis affect resetting systems for the products. The work was done with a process and methodology based on design perspectives. This process has involved the search of relevant data which has provided the platform and opportunity for appropriate and purposeful design work. Concept development has been done using hand sketches and Photoshop, where a simple visualization of different concepts for the tripods has been produced. The next step relies on evaluating concepts in relation to the requirements and likings collected and the best concept has been chosen and developed. The design work was based primarily on work in SolidWorks to simultaneously maintain an ongoing partnership in the project, involving development of the resetting and design features. In this way, a link between design and construction has been active through the whole project. Where design at first took account for the changes made in the construction based developments. In this way, the products has been optimized and developed in a context where the design meets the construction to achieve the best results. Design developments that’s been done required an expression of keywords within the semantics and other design features. This has resulted in two products in terms of concepts and prototypes which were developed with help from clients and sponsors. The prototypes showed good results and has fulfilled the required specifications.

Full textAbstract:
The shooting sport is one of the most widespread sports in the world and it is being practice in most countries. Based on their own experiences, in competition - and hobby shooting, the client M4Solutions found a demand and need for a shooting target that is manufactured in Sweden. The purpose of the project has been to develop, with the help of Marcus Walldén, two shooting targets from idea to finished product. These two shooting targets, Plate Rack Target and Dueling Tree, would each be equipped with a mechanical resetting system but will in the future have the ability to be provided with an electronic resetting system. The project from the client was divided into two theses. One of these two, written by Marcus Walldén, focused on the tripod parts and the overall design work for both Plate Rack Target and Dueling Tree. The thesis that is presented in this report have focused on resetting systems, the design of protective plates and other peripherals for both shooting targets. This work has primarily been in CAD environment where design, construction and development has been given free rein. Calculations, test shootings and choice of materials has been made in order to reach the best possible solutions. The thesis resulted in two complete 3D models and two full-scale prototypes of steel.

Thesis (S.B.)--Massachusetts Institute of Technology, Dept. of Mechanical Engineering, 2004.Includes bibliographical references (leaves 38-39).
The hydrodynamics of free-surface impacts are of great interest to scientists across many disciplines including ocean engineering, fluids mechanics, and biology. This thesis focuses on designing a mechanism to shoot small projectiles downward. Two pneumatic shooting mechanisms were investigated: the potato gun and the paintball gun. Adaptations were made to the paintball gun, as a preliminary design; however, it was later concluded that pneumatics were not the best way to propel the projectile. The final design includes a pinball shooter to propel the ball and an electromagnet to suspend the ball before shooting. This shooting mechanism uses magnetic balls of diameter 1 inch and can achieve velocities of 278 m/s when located 1 m above the free surface. The adaptability of the mechanism to other downward shooting situations is discussed.

Full textAbstract:
A detailed study has been made of the distribution of lead on a public shotgun range in the George Washington-Jefferson National Forests in southwestern Virginia. Sampling of more than 100 sites has yielded data on the distribution pattern of the lead shot. Since opening in 1993 through 2000, 11.1 metric tons of lead has accumulated over an area 220 by 300 m (66,000 m2) with an average rate of accumulation of 1.4 metric tons per year. More than 85 % of the total dispersed lead lies scattered in the forest that surrounds the approximately 60 by 60 m cleared shooting surface. Lead is irregularly distributed because of the use of stationary targets and the general trajectory of launched clay targets. Maximum concentrations occur at distances of about 28 m about 80 m, and at about 180 m reach a maximum value of more than 5000 g per m2. Significant amounts of fine particulate lead, generated during shooting and as a result of impact occur close to the shooting box but absent at distances beyond 50 m.Master of Science

Full textAbstract:
The role of exposure to a human-made disaster and the subsequent development of post-traumatic stress reactions were examined. Subjects included 49 males and 30 females who were variously exposed to the Luby's shooting incident in Killeen, Texas in October of 1991. Post-traumatic stress symptomatology was measured by the SCL-90R. Exposure was operationalized by using a scenario-rating scheme with independent raters estimating each subject's level of exposure. A regression and commonality analysis revealed that exposure is an important predictor in post-traumatic symptomatology. Premorbid functioning and gender were also found to play important roles, with females expressing higher levels of symptomatology.

Mosqueda, Christopher M. "Columbine and the Myth of the Juvenile Superpredator." BYU ScholarsArchive, 2020. https://scholarsarchive.byu.edu/etd/8716.
Full textAbstract:
Mass media has great influence over its audience. When a sensational story hits the news waves, the general public's attention is instantly riveted to the television screen. News stories that involve the deaths of innocent people often create a culture of fear, fuel false narratives, and scatter misinformation. In fact, this culture of fear, coupled with misleading information, created the myth of the juvenile superpredator, a phrase coined by DiIulio in the early 1990s. The stereotyped superpredator was a homicidal, uncontrollable youth hiding within areas where crime and violence are rare. In particular, this myth was propagated following the massacre at Columbine High School in 1999. Across time, misinformation and false narratives served to spotlight the perpetrators' notoriety—their ultimate motivation for perpetrating this heinous attack. News media, law enforcement, and school administrators are in the unique position to stop the spread of misinformation and prevent school shooters from gaining the fame they desperately seek, a common motivation among school shooters and copycat perpetrators. This study seeks to explore how the media portrayed the Columbine High School shooters and how it fed into the myth of the juvenile superpredator. This study analyzed youth violence risk factors in the wake of the Columbine High School Shooting to determine if news media was accurate in their reporting. We wanted to determine if news coverage was a major influence on the public's perception of youth violence. These risk factors were scrutinized from television news coverage from national news organizations. Results indicate that in the wake of school shootings, strong considerations regarding ethical news reporting and clearer lines of communication between school administrators and law enforcement officials may prevent misinformation from spreading in the first place and may prevent school shooters from gaining notoriety in such aftermaths. Additionally, curtailing the spread of misinformation may help communities prevent reactionary policies that ultimately harm school students through overly punitive measures.

Full textAbstract:
Competitive Shooting as a sport is becoming famous these days and analysis of shooting group or bullet group which is a process of analysis location of bullet holes in one shooting session and stands as a metric for Precision of the weapon, Shooter's Accuracy, his Consistency and helps in finding Accurate load for the Cartridge. Knowledge of these factors can help in improving one's shooting and fine-tuning skills as a Shooter. Bullet group is alsoinuenced by the Accuracy of Rie, Optimal hand load, free run distance, environmental conditions like humidity, temperature, ambient light, windspeed, Shooter's position. Analyzing the Bullet group can be done in various ways, one way of doing it is by taking a Digital Image and analyzing the Image and detecting positions of bullet holes and Calculating metrics from this Metrics like Geometry of bullet group, largest distance between two bullets, compactness of the bullet group on target. In this work, detection of bullet holes is done by using these techniques: Template matching, Histogram equalization, White Balancing, Median andGaussian altering and Peak detection algorithms. After obtaining positions of the bullet holes in the Image. Complete Automation can be done by using the training the Algorithm with a Machine learning framework with the help of Articial neural networks. The existing bullet group analysis software require the bullet group shot on a specifc target, which limits the shooters to shoot on a target of shooter's choice every time and, those targets are not universal and vary from place to place. This algorithm aims to work on various types of target, and taking a step towards making a more generalized and more versatile algorithm.

Full textAbstract:
Financial analysts play a key role in collecting, processing and disseminating information for the stock market. Selecting the best analysts among thousands of analysts is an important task for investors that determines future investment profitability. Extensive research has been dedicated to finding the best analysts of the market based on various criteria for different clienteles. The state of the art approach in this process has developed into so-called Star Rankings with lists of top analysts who have previously outperformed their peers. How useful are such star rankings? Do the recommendations of stars have higher investment value than the recommendations of non-stars (i.e., recommendations of Stars “shoot” more precisely before and after selection)? Or do star rankings simply represent the past performance that will regress to the mean in the future (i.e., in reality, Shooting Stars are not stars and quickly disappear from the sky)? The aim of this Ph.D. thesis is to empirically investigate the performance of sell-side analysts’ recommendations by focusing on a group of star analysts. This thesis comprises four papers that address two overarching questions. (1) Do star rankings capture any true skill, and, thus, can investors rely on the rankings? (Papers I and II) (2) How do market conditions impact star analysts? (Papers III and IV) Paper I examines the profitability persistence of the investment recommendations from analysts who are listed in the four different star rankings of Institutional Investor magazine, StarMine’s “Top Earnings Estimators”, “Top Stock Pickers” and The Wall Street Journal and shows the predictive power of each evaluation methodology. By investigating the precision of the signals that the various methodologies use in determining who the stars are, the study distinguishes between the star-selection methodologies that capture short-term stock-picking profitability and the methodologies that emphasize the more persistent skills of star analysts. As a result, this study documents that there are star-selection methods that select analysts based on more enduring analyst skills, and, thus, the performance of these methods’ stars persists even after ranking announcements. The results indicate that the choice of analyst ranking is economically important in making investment decisions. Paper II investigates the structure of the portfolios that are built on the recommendations of sell-side analysts and confirms that the abnormal returns are explained primarily by analysts’ stock-picking ability and only partially by the effect of over-weight in small-cap stocks. The study examines the number of stocks in the portfolios and the weights that are assigned to market-cap size deciles and GICS sectors and performs an attribution analysis that identifies the sources of overall value-added performance. Paper III examines the differences in seasonal patterns in the expected returns on target prices between star and non-star analysts. Although the market returns in the sample period do not possess any of the investigated seasonal effects, the results show that both groups of analysts, stars and non-stars, exhibit seasonal patterns and issue more optimistic target prices during the summer, with non-stars being more optimistic than stars. Interestingly, the results show that analysts are highly optimistic in May, which contradicts the adage “Sell in May and go away” but is consistent with the notion of a trade-generating hypothesis: since analysts face a conflict of interests, they may issue biased recommendations and target prices to generate a trade. A detailed analysis reveals that the optimism cycle is related to the calendar of companies’ earnings announcements rather than the market-specific effects. Paper IV discusses how a shift in economic conditions affects the competitiveness of sell-side analysts. The focus is on the changes that were triggered by the financial crisis of 2007-2009 and a post-crisis “uncertainty” period from 2010-2013. The study follows Bagnoli et al. (2008) in using a change in the turnover of rankings as a measure of a transformation in analysts’ competitive advantages. Paper IV extends their research and documents how different ranking systems capture analysts’ ability to handle changes in the economic environment. The results show that market conditions impact analyst groups differently, depending on the group’s competitive advantages.QC 20170412

Full textAbstract:
The purpose of this research was to examine the influence of fictitious scoring updates on psychological momentum (PM) and athletic performance in a competitive basketball setting. The participants included in this study were 50 male undergraduate students who reported having played basketball previously and qualified by being able to make more than 24% (12 out of 50) of their 3-point shots in a pre-trial session. Participants were told that they were competing in a 50 shot, 3-point shooting competition against another individual, equal in ability. After every 10 shots, participants were given a fabricated score update and answered four questions used to measure PM. Results showed that the fictitious score updates significantly (p < .01) influenced participants’ PM scores, where those who were told they led had higher PM scores than those who were told they trailed. As for shooting performance, no significant differences (p = .76) were found between positive and negative PM states for participants who reported experiencing both during the competition. Together, these findings suggest that manufactured score updates can influence PM, but resultant performance differences may not exist. Results of this study lend support to the notion that PM is experienced by athletes. However, when examining basketball shooting performance, the momentum-performance relationship is statistically unsupported. Thus, although PM is thought of by many as a game-changing factor, this study would suggest that PM plays a negligible role in changes to individual performance.

Full textAbstract:
The continual occurrence of school shooting incidents underscores the need of taking preventive measures. Inductive measures of threat assessment have proved to be a bad strategy to solve the problem and new research is focusing on deductive approaches. Deductive threat assessment approaches are gaining ground and efforts are underway to mine text for automatic detection of threats in written text. Automatic detection and classification of threats in the digital world can help the decision makers focus energies on imminent threats of school shooting and take preventive measures in time to save precious lives and other resources. The contribution of this study is criticism of the previous work done on the problem of school shooting, collection of data of previous cases of school shootings in order to find out the factors that affect the school shooting problem and the development of an algorithm that could be used to detect threat of school shooting in written text in the English language. The algorithm proposed in this study classifies text on the basis of seriousness of the threat of school shooting in to four categories i.e., "High", "Medium", "Low", and "Not a threat". The seriousness of the threat is decided based on different indicators present in the text of the threat and presence of factors that has affected previous school shooters. A prototype is implemented to demonstrate the classification in to the categories mentioned above.

This thesis is an inquiry that examines how those who are marked different in school are also marked "wrong" and marginalized and how that marking often leads to bullying. It examines the significance that those markings have on those who are marked, on those who mark and on those who are witnesses. This is an analysis of bullying and a critique of an institution's response to bullying and its deleterious effects. The writing offers a connection between the particular and the universal. It tells of my personal experience while I was a teacher at a small town high school before, during and immediately after a violent incident that resulted in a death, against a backdrop feminist, critical, poststructural and postmodern theory, and academic dialogue that has helped me come to some understanding of the dominant discourses at play within this story. The writing is not merely the mode of telling the writing is the way to understanding, which must always precede the telling. Finally this thesis is a search for a healing home in which home-ness means a place open to being, rather than a place that defines the "right" way of being.xii, 134 leaves : ill. ; 28 cm.

Full textAbstract:
Many predatory species cause negative impacts on human interests by threatening game, livestock or human safety. These impacts can create conflicts where stakeholders differ over wildlife management and when one party is perceived to exert their interests at the expense of the other. Finding effective methods to mitigate conservation conflicts requires an interdisciplinary perspective that investigates (i) the reality of the apparent impacts, (ii) the efficacy of any methods intended to remedy them and (iii) the perceptions, motivations and objectives of key stakeholders. In this thesis, I investigated a conservation conflict in the U.K. surrounding predators and game management. I did so with specific reference to the common buzzard Buteo buteo, a species that, due to predation of released pheasants Phasianus colchicus, is both subject to illegal persecution and on- going controversy concerning the licenced selective removal of ‘problem individuals’. I first review the literature to assess the ecological evidence that certain ‘problem individuals’ can be both disproportionately responsible in impacts upon human interests and more likely to reoffend. I show that while there is evidence for these animals across many different taxa, the benefits of their removal can sometimes be short-lived. I highlight possible indirect impacts of selective management and identify it as a potential compromise between different stakeholder groups. Next, I evaluate the performance of Bayesian stable isotope mixing models (BSIMMs) in quantifying the diets of wild animals. By comparing indirect and direct observations of buzzard foraging, I demonstrate that, with the correct selection of trophic discrimination factors, stable isotope analyses can provide a reliable picture of dietary composition that mirrors direct observations. I then apply these mixing models to evaluate the ecological basis of selective removal of ‘problem buzzards’. The results suggest that the consumption by buzzards of released pheasants is not limited to release pens where gamekeepers perceive buzzard predation to be a problem. However, I then show that stable isotope analysis of blood sampled from two of the four buzzards caught inside pens indicates frequent consumption of released pheasants, relative to the rest of the buzzard population. These results suggest that, while some pheasant consumption may go undetected, selecting only buzzards inside pens for removal is likely to target ‘problem birds’. I then investigate buzzard foraging and breeding ecology on land managed for pheasant shooting. I find that buzzards nest at higher density in areas with greater abundances of pheasants and rabbits Oryctolagus cuniculus. However, records of provisioning from nest cameras showed that only rabbits were caught in proportion to their abundance and only rabbit provisioning rate was associated with buzzard productivity. I suggest that the positive relationship between buzzard and pheasant abundance, although seemingly unconnected to pheasant predation, might influence how gamekeepers perceive buzzard impact. Next, I conduct semi-structured interviews on the subject of predator control with 20 gamekeepers across the south of England, to explore the underlying beliefs, norms and information sources that motivate their behaviour. From these interviews, I identify a number of separate, but interconnected, motivations that influence predator control including professional norms, potential penalties, and interpretations of what is ‘natural’. The influences of these motivations are discussed in detail and a conceptual model, incorporating the theory of planned behaviour, is developed. Finally, the key contributions of this thesis are drawn together and discussed in their wider context. Taken together, the results of this thesis illustrate how predator management occurs simultaneously within social and ecological contexts that incorporate the individual attributes of both predators and people. The results of this thesis have direct implications for the management of predators, the representation of stakeholder perspectives and the design of conflict mitigation measures.

Full textAbstract:
Shooting ranges concentrate significant quantities of heavy metals, especially lead as spent shot and bullets, on very small parcels of land. Samples taken from a shooting range near Blacksburg, VA, USA provide information about the reservoirs and pathways of lead at shooting ranges in an upland setting and humid environment. Metallic lead corrodes rapidly and develops a coating of corrosion products. The type and amount of corrosion products found on lead shot and bullets are best understood through examination of Eh-pH relationships. X-ray diffraction analysis identified hydrocerussite (Pb₃(CO₃)₂(OH)₂) as the corrosion phase present on lead shot recovered from the range. Hydrocerussite dissolution can produce soluble lead concentrations ranging from 2 ppb to 2 ppm for the soil pH values at this site. This soluble lead is captured by the soil. Sequential chemical extractions revealed that vertical lead migration beyond the A-horizon was minimal. The bound-to-Fe & Mn oxides and bound-to-carbonates soil fractions were identified as significant reservoirs for sequestration of lead in the soil. The highest concentration of extractable lead contained in the soil was directly correlated with the highest concentration of lead shot and bullets measured on the shotgun range surface. The geochemical framework for understanding the corrosion process, identifying the corrosion product(s) that control lead solubility, and identifying the geochemical barriers to lead migration that were employed at the Blacksburg, VA shotgun range, provides a basis for selecting best management practices for this and other shooting ranges.Master of Science

Full textAbstract:
The aim of the work presented in this thesis is to develop a method of characterising the shape of curves in the plane that is independent of the parameterisation of the curve. It is important to remove the effect of a specific parameterisation of a curve because it is possible for two curves to have the same shape while having different parameterisations. The characterisation is accomplished by matching curves via deformations, and using the deformations to characterise the difference between them. We specifically aim for a method that is able to characterise the kind of complex curves found in cross sections of the human nasal cavity. In order to match one curve to another, we derive the equations of motion for a geodesic flow, and seeking the flow that deforms an embedded reference curve into the target curve we wish to characterise. The geodesic flow is itself characterised by a conjugate momentum on, and normal to, the reference curve, giving a one dimensional descriptive signal of the deformation. This descriptive signal contains all of the information required to generate the target curve from the reference curve. We therefore say that this descriptive signal characterises the target curve with respect to the reference curve. The descriptive signal is found using a shooting approach, requiring a functional to measure how closely overlaid are two curves. Formulating the problem as an optimisation problem, we first present a parameterisation-independent functional based on geometric currents, but show that we encounter problems in this matching functional due to local minima. We then present a second approach in which we formulate the problem as a landmark matching problem. Since we seek a characterisation that is independent of the choice of landmarks, and the landmark matching functional is parameterisation dependent, we minimise the functional over all reparameterisations of the reference curve. These two approaches solve equivalent problems. We present the results of the reparameterisation-based matching, and show that they overcome the problems observed in the currents-based method. In particular we demonstrate that the method is able to match complex nasal geometries, and show how the descriptive signal can be used to interpolate between two dimensional slices of three dimensional objects to reconstruct three dimensional surfaces representing the objects. Though here we implement the geodesic flow in two dimensions, we note that the flow could be extended to three dimensional space. Since the reparameterisation based matching functional is trivial to implement in three dimensions, this would allow for the characterisation of both curves and surfaces in three dimensional space.

Full textAbstract:
The purpose of the study was to investigate the effects of muscle fatigue on shooting accuracy in male handball players. Sixteen elite young male handball players (age: 17.12±1.74 year
height: 185.26±
7.17
body mass: 78.93±
11.07) volunteered to participate in the study. The study composed of laboratory and field test sessions. In the laboratory test, maximal oxygen consumption (VO2max) obtained from treadmill running test, blood lactate concentration, heart rate monitoring at resting and every 3 minutes during running were measured. Running speed equal to 75% speed at VO2max values of participants was used as initial velocity for 30-15 intermittent fitness test (30-15IFT). In the field tests, after determined the optimum shooting velocity of each participant, they shots to each targets placed at the four corner of the handball goal 4 times, totally 16 times. Blood lactate concentration was measured from the earlobe of participant who completed shooting to target test session. Then, 30-15IFT was applied as fatigue protocol and at the end of the test, blood lactate concentration was measured again and participant repeated shooting to target test session immediately after fatigue protocol. During all shooting procedures, acceleration of wrist and speed of ball were recorded. Blood lactate concentration over 8mmol/L, v 90% of HRmax, respiratory exchange ratio>
1 and exhaustion of participant accepted ending criteria for the tests. As a result, no significant differences were found between pre-fatigue and post-fatigue protocols in terms of accurate and inaccurate shots. Shooting consistency, ball speed, response time, X, Y, Z axis of wrist acceleration variables highly correlated each other in terms of shooting accuracy both in pre and post fatigue conditions. Shooting consistency has an effect on accurate shots. Ball velocity has effect on inaccurate shots in pre-fatigue condition. However, none of variable has effect on accurate and inaccurate shots in post-fatigue conditions. In pre-fatigue conditions, right to left motion of wrist (X axis) was the most important motion, back to forward motion (y axis) was became more important in post fatigue condition.

Full textAbstract:
An earlier study of shooting performance in biathletes found a decrease in performance as the intensity increased. No studies have focused on the technique used by biathletes in standing shooting, which differs from the technique used by rifle shooters. Therefore, the present study investigated both shooting performance at different exercise intensities in biathletes, and the difference between isometric and dynamic precision at different intensities. To investigate shooting performance at different intensities, 15 biathletes performed three roller ski interval exercises (4x6 min) on a treadmill at 75-80%, 85-87% and 90-95% of their maximum heart rate (HRmax).The biathletes performed 3 precision tasks at rest before warm up, directly after warm up and after each repetition on the interval exercises. The following precision tasks were performed (in standing position): 5 shot series, holding still at a target (isometric), and following a line (dynamic). During the precision tasks, the subjects were standing on a force plate that measured center of pressure (COP) movements in the anterior-posterior direction and medial-lateral direction. Subjects used their own weapon in the precision tasks. A laser pen and an accelerometer were attached at the front of the barrel. The "front sight" was removed from the weapon, and subjects used only their rear sight and the laser dot for aiming. The results showed no significant effect of intensity on shooting performance during the 5 shot series (p= 0.179). The holding still task and following line task were both significant affected by intensity (holding still p= 0.017, following line p= 0.030), but the difference between the two tasks did not reach statistical significance (p= 0.070). Results from the force plate showed greater movement of COP in the anterior-posterior direction than in the medial-lateral direction. A significant effect of intensity was only found in the medial-lateral direction. In conclusion, the present study shows no significant effect of intensity on the shooting performance in the 5 shot series. The subjects were not used to having a laser pen for aiming, and this may have affected the results. There is a difference between isometric and dynamic precision, but the difference did not reach statistical significance. Thus, the results cannot for certain justify the technique used by biathletes in standing position.

Full textAbstract:
After the terrorist attacks that took place on September 11, 2001, on American soil, a plethora of norms that enable military forces to shoot-down hijacked civil aircraft have been passed in several countries. Although these laws, decrees and executive orders are grounded on security reasons and they are allegedly aimed to protect people and vital interests on ground, this assertion does not emasculate the main difficulty they face in legal terms, which is the existence of an international provision that forbids the use of force against civilian aircraft. This thesis contains a detailed list of such domestic norms and conducts an analysis of their validity from the perspective of Article 3bis of the Chicago Convention and the right of self-defense granted to states by the Charter of the United Nations.

Full textAbstract:
This thesis considered the kinematic factors associated with elite pistol shooting performance. The first three studies examined performance in the newly introduced modern pentathlon combined event. Study 1 demonstrated that shooting performances differed significantly between the combined event and the original precision shooting format. Pistol shooters achieved significantly higher scores, and significantly smaller pistol and centre of pressure movements, than modern pentathletes in the precision event (p < .05). No significant differences were evident between the groups for combined event shooting (p > .05), highlighting that the most successful precision shooters were not guaranteed success in the combined event. Studies 2 and 3 examined how shooting performance changed within and between each shooting series. Aiming time did not change significantly within any series (p > .05), and so participants experienced a similar degree of pistol and centre of pressure movement for each shot, and achieved similar scores. No significant differences were evident in shooting performances between each shooting series (p > .05), despite the additional 1 km run phases. Thus, each running phase appeared to have little impact on shooting performance. Individual analysis used in each study highlighted the extent of individual variation in shooting performances, and demonstrated that group analysis is not sufficient to reflect the performances of individual participants. The final two studies examined elite precision shooting performances. Study 4 provided a descriptive analysis of torso, shoulder, wrist and pistol movement during the final second before the shot. Participants produced variable movement patterns for the upper limb, reflecting the principle of abundancy, in order to control the motion of the pistol. The exact patterns varied between participants, further supporting the importance of using individual analysis to examine pistol shooting performance. Study 5 examined the effects of stance position on shooting performance. Changing stance position produced significant differences in the scores achieved by each participant (p < .05). The most effective mediolateral and anterior-posterior stance widths, and the mechanisms behind the changes in performance, varied between participants. Thus, it was recommended that pistol shooters should examine stance position in greater detail when attempting to enhance performance.

Thesis (Ph. D.)--Massachusetts Institute of Technology, Dept. of Political Science, February 2007.Page 642 blank.
Includes bibliographical references (v. 2, p. 575-641).
The study explores the nexus between illicit economies and military conflicts. It investigates when and how access by belligerents to the production and trafficking of illicit substances affects the strength of belligerents and governments. Although narcotics trafficking is often treated as sui generis, the study situates the drug trade within the larger class of markets for illicit products and services. The study presents a general theory of the relationship between illicit markets and military conflict - the political capital of illicit economies -- and contrasts it with conventional wisdom on connections between drug trafficking and military conflict. The political capital of illicit economies argues that belligerents derive much more than simply large financial profits from their sponsorship of illicit economies. They also obtain freedom of action and, crucially, legitimacy and support from the local population, called political capital. If belligerents choose to become negatively involved in the illicit economy (attempt to destroy it), they not only fail to increase their military capabilities, but also suffer costs in terms of political capital. The extent and scope of belligerents' gains/ losses from their involvement in the illicit economy depend on four factors:
(cont.) the state of the overall economy; the character of the illicit economy; the presence of traffickers; and the government response to the illicit economy. These factors reflect both structural conditions outside of the immediate control of the belligerents and the government and strategic policy choices available to either the belligerents or the government. Contrary to the conventional wisdom about narcotics and military conflict, eradication of narcotics cultivation has dubious effects on the capabilities of the belligerents and is extremely unlikely to severely weaken them. However, it alienates the local population from the government and results in the population's unwillingness to provide intelligence on the belligerents - a crucial requirement for success against the belligerents. Thus, eradication of illicit crops increases the political capital of the belligerents without significantly weakening their military capabilities. The primary cases explored in the study are Peru, Colombia, and Afghanistan. Additional evidence is drawn from the cases of Burma, Northern Ireland, Turkey, and India.

Refletir sobre o mundo contemporâneo nos leva a considerar fatores, tais como os rompantes de violência em uma sociedade. No nosso caso, voltamos nosso olhar para os Estados Unidos, buscando compreender como essa violência e mais especificamente o school shooting se tornou um ícone que nos remete aquele país. Para tanto, a investigação é centrada em duas produções cinematograficas: Elephant (2003) de Gus Van Sant e Bowling for Columbine (2002) de Michael Moore. Os dois filmes são resultado de um mesmo evento: o massacre ocorrido em Columbine High School em 20 de abril de 1999. Por meio da sensibilidade de Gus Van Sant e da assertividade de Michael Moore buscamos analisar de que maneira esse tipo de episódio nos Estados Unidos da América é um fenômeno cultural e, para tanto, recorreremos a estudos sociológicos, como os desenvolvidos por Cohen e Tonry. Tais estudos nos auxiliarão a repensar e melhor compreender como crianças e adolescentes abrem fogo dentro de uma escola e a significação desse acontecimento.
To reflect about the contemporary world leads us to consider many factors, such as the outbreaks of violence in a society. In our case, we turn our gaze to the United States of America, seeking to understand how this violence, and more specifically the school shooting, has become an icon that brings us back to that country. To do so, this research is centered on two cinematographic productions: Elephant (2003), by Gus Van Sant, and Bowling for Columbine (2002), by Michael Moore. Both films are the result of the same event: the massacre at Columbine High School on April 20, 1999. Through the Gus Van Sant’s sensitivity and the Michael Moore’s assertiveness, we sought to analyze in wich ways this kind of episode, in the United States of America, is a cultural phenomenon, and to do this we will resort to sociological studies such as those developed by Cohen and Tonry, to broaden and rethink what tools would enable us to better understand how children and teenagers open fire within a school and the significance of that event.

Full textAbstract:
The present study examined the relationship between coping and psychological and psychosomatic distress of 25 individuals who experienced the same severe, acute traumatic event: the violent shooting that killed 23 people and severely injured 20 more in Luby's Cafeteria in Killeen, Texas, on October 16, 1991. Distress was assessed by one-month pre-event and post-event scores on the SCL-90R, Psychosomatic Questionnaire, and by a Life Event Questionnaire score for the year before the incident. Coping was measured by a modified version of the Ways of Coping Scale (Folkman et al., 1986) and Response Style Questionnaire (Nolen-Hoeksema & Morrow, 1991). All post-event distress scores, except the Psychosomatic score, significantly increased over their corresponding pre-event scores regardless of gender. Although female distress scores were consistently higher than male scores, gender was predictive of post-event distress only for the SCL-90R Anxiety, Somatization, and Global Severity Index scales. The only pre-event score found to be predictive of post-event distress was the Psychosomatic scale. Regression analysis, with demographic and pre-event variables controlled, found a significant positive relationship between Escape/Avoidance coping and one-month post-event levels of Anxiety and Psychosomatic distress. Findings were discussed in the context of the process-oriented stress-illness model and were compared to current disaster and crime victimization literature. Implications for helping professionals, methodological issues, and implications for future research were explored.

In Olympic and Asian Games, the numbers of shooting’s medal are only next to athletics and swimming. There are 44 shooting gold medals in Asian Games (individual and team), and 15 ones in Olympic Games(individual only). Besides the numbers of medal, shooting is a sport that fits Asian countries perfectly. Shooting competition can be categorized in four major sections, pistol, rifle, running target and clay target. In the last, it’s divided into skeet, trap and double trap subsections. Clay target shooting has 12 gold medals (men, women, and team) in Asian Games and 5 in Olympic games (men & women individual only, double trap women was cancelled in Beijing 2008). Summarized from the data above, I suggest Sports Affairs Council should put shooting sports in a long term plane. By formed the science chooseing the talent, training and becoming a outstanding shooters since juniors, the shooting sports can be developed thoroughly and competitively to win more medals in international sporting events.

The Effect of Cannister with Different Chokes and Distances on the Shooting Distribution ofShooting Locations Abstract The purpose of this study was to explore the effect of cannisters with different chokes and distances on shooting distribution and shooting locations. The method of research included experimenting with four different chokes (No. 2, No. 4, No. 6, No. 8) and seven shooting distances (22 m, 25 m, 28 m, 31 m, 34 m, 37m, 40 m.). Four different chokes were applied in each distance; therefore, there was a total of 28 variations. With the data from each variation gathered, it was analyzed using the SAS 9.1 software for comparison and a statistical analysis was performed with a two-way ANOVA. After analyzing the results, the following conclusions were: 1) close-range shooting causes highly-centralized shooting distribution because of insufficient capabilities of the choke, and produced a high number of chaffiest in the perimeter. 2) Long-distance shooting also did not show good performances, showing a highly-dispersed shooting distribution and high number of chaffiest. 3) The No. 2.Choke could be used for close-range shooting, showing the best performances and an even shooting distribution. 4) No. 4 and No. 6 chokes can be used in middle-ranged shooting, showing the best performances and an even shooting distribution. 5) The No. 8 choke can be used in long-distance shooting, showing the best performances and an even shooting distribution.

Basketball is a popular game in Taiwan and it is also an essential activity in physical education courses from elementary to senior high school. The basic skills of basketball include dribbling, passing, lay-ups and shooting. Allsen pointed out that approximately 67% of the shots during the games were jump shots, suggesting that jump shots are important in basketball games. However, jump shot is a multi-segment movement, control of this multi-segment movement is important for shooting accuracy. The movement degeneracy plays an important role in performing multi-segmental coordination. There were 7 participants who are playing in SBL recruited for this study (age (y)：22.8 ± 1.2，height (cm)：185 ± 10.1，weight (kg)：86.1 ± 10.8，training year (y)：8.8 ± 1.7). Apparatuses for the experiment included the Phasespace system (480 Hz) and two digital cameras (JVC, 30 Hz). The single hand jump shot was used as the experimental task, all participants completed 500 shots a day and one of them performed extra 1000 shots on the other day. Mean of shooting average of analyzed data was 78.6 %, for basketball jump shot, the segmental peak velocities occurred in the order of hip, knee, ankle, shoulder-elbow to the wrist. In terms of relative phase, the most stable performance of the knee-ankle and shoulder-elbow pairs coincide with the peak velocity of one or both of the involved segments which may signify the basis of a successful jump shot performance. There were no other consistent movement pattern observed in the study further provide the evidence of movement degeneracy among highly practiced performers.

Abstract The purpose of this study is to explore how the male college basketball players would be adapting themselves in long range shooting training load, to increase the percentage, efficiency and stability of 3-point shooting. There were 18 male college basketball players (average age: 21.78+2.64 years old; average height: 177.67+ 5.06cm; average weight: 72.33+ 6.74kg) participated in this study, and these players were divided in three groups: long range training group (8 meters); 3-point line training group (6.25meters); and the control group according to the pre-test results. All of the groups were given shooting training for 8 weeks (150 shots for each time, twice a week); the mid-test was given at the end of the four weeks. The data collected were processed and analyzed using 2-way mixed design, 2-way repeated measure ANOVAs and Trend Analysis with SPSS 10.0 (Windows Edition). The significant level was set for α＝.05. The finding of this study goes as follows: 1. The shooting percentage in different tests is significantly different, and there is interaction between different groups and tests (p<.05). 2. The shooting efficiency of long range group is better than control group in post-test (p<.05). 3. The ANOVA and Trend Analysis of the 3-point group is significantly different among testing period; and the players in position 3 has higher grades in the mid-test and the post-test than the pre-test (p<.05). 4. The shooting efficiency and percentage of the 3-point group is significantly better than control group, and the post-test of the 3-point group in position 1 and 3 are significantly better than the ones of control group (p<.05).

The purpose of this study was to investigate the effect of different weights of arrow points, shot from different distances, on horizontal and vertical diversions, and on the precision of the distribution of shooting locations. To study it, a homemade mechanical arm was used, the bows and arrows were set in the same condition, and various weights of points were shot from different distances. Then, the author recorded the shooting locations on the Graph paper by X-Y site coordinates, and calculated the horizontal and vertical diversions, and the precision of the distribution of shooting locations. Next, the author analyzed the data by means SAS 8.2 version software .After the analysis and discussion, the author concluded: 1.the heavier point is the greater vertical diversion of shooting location is. 2. Heavier point is helpful for the precision of 90-meters distance. 3. Heavier point is helpful for the horizontal diversion of 90-meters distance. 4. Male can choose 100-grains point in the competition for its steady precision. 5. With different weights of arrow points, the farther the distance is, the worse precision will get. 6. With different weights of arrow points, it will result in greater horizontal diversions if the distance gets farther. 7. With different weights of arrow points, more obvious vertical diversions will occur if the distance is farther.

This study examines how shooting the medicine ball from the sitting position to standing position affects spot shooting. Good shooting starts from using your force from your legs through your body to your wrist. That is why we use “Sit-and-Stand Shooting” skill to train our players to shoot from this particular position. We use a medicine ball instead of a basketball to improve our players upper body muscle and shooting percentage. Therefore we conducted this study to compare how the shooting percentage from one fixed point (percentage of made shots and missed shots), muscle forces, Rating of Perceived Exertion Scale, and heartbeat rates change before and after the training. The subjects are from the men’s basketball team of Wenhua Elementary School of New Taipei City with their age from 11 to 12 years old, height from 134 to 166cm, and weight from 29 to 70kg. Before the training, they were asked to take a spot shooting test (made shot and missed shot percentage, muscle testing, RPE level and heartbeat rate). After 8 weeks of training, they took another spot shooting test (made shot and missed shot percentage, muscle testing, RPE level and heartbeat rate). Paired-Samples T Test was used to measure their performance, Whether the test has achieved significant differences. The result shows that their upper arm muscle and free-throw shooting have improved and achieved significant differences; their the Borg Rating of Perceived Exertion Scale (RPE) and heartbeat rate have also decreased and achieved significant differences. However, their mid-range shooting percentage has improved but not achieved significant differences, while their missed shot percentage of spot shooting has decreased but not achieved significant differences.

The most important skill of pistol shooting is accuracy, shooter should be equipped with the strong skill and the high accuracy. However,most of past specialists research the way of pistol shooting and the balance when shooting, but just few specialists research the action power of pistol shooting and the body factor.In addition,pistols, the essential arms, equip military and domestic and foreign staffs in the special units, and pistol shooting belongs to the item which need accuracy and speed of shooting highly. It relys on the close cooperation between people and pistols. This reaserch shows the mutual relationship of close relationship between people and pistols and the accuracy of pistol shooting from an engineering perspective, and employs the technical ways of statistics and regression analysis to establish the whole shooting regression model and the factors of impacting shooting efficiency. Through individual and people from the regressions,we can predict and experiment whether the change of setted factor considerably influence the accuracy of shooting. On the other hand,the research experiment how to make a balance between the point of application and shooting efficiency to show the result of better shooting accuracy.

Some people don’t like reading abstract because it’s too boring and unattractive. But if you are a beginner at shooting or have learned shooting for while but lack of progress, you’ll find this report useful. Professional opinions from experts, related literature, and empirical experience are all included in the study and it helps you develop shooting knowledge and also make progress in shooting performance. By sharing the successfully experience and skills, it is hoped that readers could become excellent shooters in the future. For the view point of competitive sport development, there is one common characteristic in modern competitive sport training- to explore the potential of athletes through various scientific ways to the direction of ultimate sport performance. Therefore, we could see the importance of sport sciences. The foundation of sport techniques lies in power, endurance, speed, flexibility, and coordination. But besides above physiological factors, psychological, technical and tactical factors are also important. These factors decide the future development of an athlete. With the increasing level of modern competitive sport in terms of techniques, more problems regarding to training for athletes are waiting to be resolved. To promote the development of shooting in Taiwan, find the best results for shooting, and develop the basic theoretical system for shooting theory based on previous successful experience, we are striving for the integration of theory and practice objectively, scientifically, systematically and comprehensively. We know it is not easy to have scientific training especially for a discipline which doesn’t require ultimate power but put high demand on psychological stress, we have to be more cautious when trying to reach the balance. Based on the foundation of precious knowledge and previous successful experience, we hope this technical report could help the research development of scientific training in shooting.

The objective of research is to design an auto shooting system by using industrial robot arm with a laser device. It can track and shoot virtual balloons in an interaction game system. Auto shooting system is designed by position based visual servo control frame. The object information is obtained by a fixed camera and Kalman filter is used to predict the position of the balloon which is subsequently used as an input signal of controller. Next, the Jacobian matrix of the robot arm is used to calculate the responsive angular velocity commands of each joint. The interaction game system uses other camera to play as a judge device. If the laser dot is found inside in the region of the balloon on the projection screen, the balloon is considered shot and will burst. Confirmed by a large number of experiments, the proposed shooting system can guide the robot arm to track and shoot the objects successfully.
