From the Desire to Mark Essex: The Catalysts of Militarization for the New Orleans Police DepartmentMartin, Derrick W.A. 13 May 2016 (has links)
Abstract
The ultimate goal in the South was to end segregation, but nationwide equal-rights were the common goal of all African-Americans. Nonviolent protests and over aggressive police departments became the norm within the African-American community. Understated in the history of the Civil Rights Era is the role of armed resistance and Black Nationalism. Marcus Garvey, Stokely Carmichael, Huey P. Newton, and Malcolm X were Black Nationalists that led the charge of Black Nationalism worldwide. The Deacons of Defense, the Lowndes County Freedom Organization (LCFO) and the Black Panther Party for Self Defense transformed the social makeup of the country and became major causes of the militarization of police departments across the United States. Many police departments across America began to create SWAT teams and use military-style weaponry following an outbreak of riots and the assassination of Dr. Martin Luther King Jr. In New Orleans, Louisiana, stand-offs and shoot-outs with Black Panther members warranted a call for military backup, but it was the acts of Mark James Robert Essex that totally militarized the New Orleans Police Department.

Ab-initio studies of adsorbate-surface interactions / Estudos Ab-initio das Interações de Superfícies adsorvidasRêgo, Celso Ricardo Caldeira 17 November 2017 (has links)
This thesis supplies a contribution to the understanding of the interaction between carboncarbon surfaces, atoms with carbon-surfaces, and atoms with metallic surfaces. It is well established that the surface-surface and atom-surface interactions are interesting, important and challenging for reasons that vary from industrial interest up to the academic necessity of understanding it deeply. Currently, there are many measurements and simulations for the geometric and electronic properties of Graphite, these differ by more than 40%. This implies that our understanding of the nature of this material is quite poor. The interaction between small transition-metals clusters with a Graphene sheet is another example where our knowledge is very limited. There are many theoretical studies in the literature that describe the interaction between these clusters with a Graphene sheet, but they agree and disagree on many points, which calls for systematic study of this issue. In this thesis we will focus our efforts on studying the surface-surface and atom/clusters-surface interactions. This thesis is split into three projects. The first aims to contribute to the understanding of the interlayer interactions of the bulk Graphite. In the second, we intend to shed some light on comprehending the interaction of an adatom with a Graphene sheet. Both of these projects, are studied within DFT framework with the inclusion of the van der Waals (vdW) corrections. In the Graphite project, we found that the electronic and geometric properties depend on the vdW correction employed in the calculation. In the adatom supported on Graphene project, we combined a modified Anderson-Newns model to describe the coupling between the adatom with Graphene. In addition, we found the existence of competition between quantum and classical forces, which determine the type of site in which the adatom prefers to adsorb. The last project is a dynamical study of an atom that impinges upon a metallic surface. In this project, we focus on the calculation of the sticking coefficient, a measure of the amount of nuclear density attached to the metal surface after collision. At this time the project is not one 100% ready, but our preliminary results indicates that, a small part of the nuclear density stays stuck on the metal. / Esta tese ajuda a entender as interações entre duas superfícies de carbono.

As interações superfície-superfície e átomos-superfícies são importantes por razões que variam desde o interesse industrial até a necessidade acadêmica para compreendê-la profundamente.

Tais medidas diferem em mais ide 40% umas da outra. Isso mostra que nossa compreensão sobre a natureza desse material ainda é bastante pobre. A interação entre pequenos grupos de metais de transição com uma folha de grapheno é outro exemplo em que nosso conhecimento é limitado. Existem muitos estudos teóricos na literatura que descrevem a interação desse tipo de aglomerado com uma folha de grafeno, porém há numerosas discordâncias. Tais controvérsias parecem suplicar por um estudo sistemático. Nesta tese focamos nossos estudos nas interações superfície-superfície e de átomos ou aglomerados atômicos com superfícies de carbono e de um metal. A tese foi dividida em três projetos. O primeiro visa compreender melhor a interação entre as camadas do grafite. No segundo, pretendemos lançar alguma luz no entendimento da interação de átomos e aglomerados atômicos com uma folha de grafeno. Esses dois projetos, são estudados à luz da Teoria do Funcional da Densidade com a inclusão das correções van der Waals (vdW). No Projecto sobre o grafite, mostramos que as propriedades eletrônicas e geométricas dependem do tipo de correção de vdW empregada no cálculo. No projeto sobre átomos e aglomerados atômicos adsorvidos no grapheno, combinamos um modelo modificado de Anderson-Newns para descrever o acoplamento entre um átomo adsorvido e o grafeno. Além disso, encontramos uma competição entre forças quânticas e clássicas, a qual determina o tipo de sítio no qual o átomo prefere ser adsorvido. O último projeto é um estudo dinâmico de um átomo colidindo contra uma superfície metálica. Nesse projeto o foco é posto no cálculo do coeficiente de aderência, o qual mede a taxa de densidade nuclear presa na superfície metálica após a colisão. Resultados preliminares indicam que, uma pequena parte da densidade nuclear permanece aderida ao metal depois da colisão.

Radiative corrections to hadron production in e+e- annihilations at DA(Phi)NE energiesHoefer, Axel 08 March 2002 (has links)
Strahlungskorrekturen zur Hadronproduktion bei niedrigen Energien, wie man sie an den e+e- -Beschleunigern DAFNE und VEPP-2M misst, werden untersucht. Ziel dieser Arbeit ist es, die von QED--Korrekturen befreiten hadronischen Wirkungsquerschnitte aus den hadronischen Daten mit einer Praezision auf Promille-Niveau zu extrahieren. Hadronische Praezisionsdaten werden benoetigt, um den theoretischen Fehler zur laufenden Feinstrukturkonstanten alpha(s) und zum anomalen magnetischen Moment des Myons a(mu) zu senken und sie stellen daher einen Schluessel zur moeglichen Entdeckung ``neuer Physik'' dar. Insbesondere die Paarproduktion geladener Pionen e+e- -> pi+ pi- unterhalb einer Energie von 1 GeV ist von grosser Wichtigkeit. Zu diesem Prozess werden die vollstaendigen O(alpha)-QED-Korrekturen zum Anfangszustand, Endzustand sowie die Interferenzkorrekturen berechnet. Analytische Formeln zu den virtuellen und reellen photonischen Korrekturen werden angegeben. Der totale Wirkungsquerschnitt sigma, die Pion-Winkelverteilung dsigma/dcos(theta) und die Invariantemasseverteilung des Pionpaars dsigma/ds' werden fuer den Fall realistischer kinematischer Schnitte untersucht. Es wird gezeigt, dass zusaetzlich zu den vollstaendigen O(alpha)-Korrekturen zusaetzlich die photonischen Anfangszustandskorrekturen der Ordnung O(alpha^2) und fuehrende Photonbeitraege der Ordnung O(alpha^3) sowie Beitraege zur e+ e- -Paarabstrahlung vom Anfangszustand beruecksichtigt werden muessen wenn mindestens eine Genauigkeit auf Prozent-Niveau verlangt wird. Fuer die Datenanalyse wird der Schwerpunkt auf eine inklusive Behandlung aller Photonen gelegt. Die Messung sowohl des totalen Wirkungsquerschnitts als auch der pi+ pi- Invariantemasseverteilung betreffend wird der theoretische Fehler dieser Behandlung der Strahlungskorrekturen mit 2 Promille abgeschaetzt. Ausserdem wird die Modellunsicherheit als Folge der Pion-Substruktur diskutiert. Um den Formfaktor mit der gewuenschten Praezision aus den experimentellen Daten extrahieren zu koennen, wurde ein auf diese Fragestellung zugeschnittenes Fortran-Programm geschrieben, welches die Beruecksichtigung realistischer kinematischer Schnitte erlaubt. Insgesamt erfuellt die Genauigkeit der theoretischen Vorhersagen die Erfordernisse der Niedrigenergie- e+ e- -Experimente wie diejenigen bei DAFNE oder VEPP-2M. / Radiative corrections to low energy hadron production as measured at the e+ e- colliders DAFNE and VEPP-2M are investigated. The goal of this work is to provide the theoretical condition for extracting hadronic cross sections undressed from QED corrections from the measured data with a precision of per mill level. High precision hadronic data are required to reduce the theoretical error of the running fine structure constant alpha(s) and the muon anomalous magnetic moment a(mu) and therefore represent a key to a possible discovery of ``new physics''. Especially the channel of charged pion pair production e+e- -> pi+ pi- below 1 GeV appears to be of great importance. To this process the complete O(alpha) QED initial state, final state and initial-final state interference corrections are calculated. Analytic formulae are given for the virtual and for the real photon corrections. The total cross section sigma, the pion angular distribution dsigma/dcos(theta) and the pi+ pi- invariant mass distribution dsigma/ds' are investigated in the regime of experimentally realistic kinematical cuts. It is shown that in addition to the full O(alpha) corrections also the O(alpha^2) and leading log O(alpha^3) photonic corrections as well as the contributions from IS e+ e- pair production have to be taken into account if at least per cent accuracy is required. For the data analysis I focus on an inclusive treatment of all photons. The theoretical error concerning this treatment of radiative corrections is then estimated to be 2 per mill for both the measurement of the total cross section and the pi+ pi- invariant mass distribution. In addition the model uncertainty due to the pion substructure is discussed. To be able to extract the pion form factor from the experimental data with the desired accuracy a dedicated Fortran program was written which allows to take into account experimentally realistic kinematical cuts. Altogether the precision of the theoretical prediction matches the requirements of low energy e+ e- experiments like the ones at DAFNE and VEPP-2M.

Hard scattering cross sections and parton distribution functions at the LHCKovačíková, Petra 19 August 2013 (has links)
Über einen Mellinraumzugang werden Methoden zur Auswertung von Wirkunsquerschnitten für verschiedene Prozesse mit Hadronen im Anfangszustand entwickelt. Die Arbeit geschieht im Hinblick auf drei Prozesse, für die die analyischen Ergebnisse für perturbative QCD Korrekturen zu “next-to-next-to-leading order” bekannt sind; diese sind: die Produktion der Vektorbosonen Z0 und W± über einen Drell-Yan-Prozess in der “narrow width”-Näherung, die Produktion eines Standardmodell-Higgs-Bosons über die Fusion zweier Gluonen im Grenzfall schwerer Top-Quark-Massen und die tiefinelastische Lepton-Hadron-Streuung über neutrale und geladene Ströme. Die Implementierung der Mellinraumtechniken erfolgt in dem c++ Paket sbp. Das Programm ermöglicht auf elegante Weise eine schnelle und präzise Auswertung von inklusiven Wirkungsquerschnitten. Wir vergleichen sbp mit den herkömmlichen Impulsraumtechniken, und präsentieren Studien der asymptotischen Konvergenz den perturbativen Reihen und von Skalenabhängigkeiten. Als Anwendung untersuchen wir welchen Einfluss die Behandlung der Faktorisierungs- und Renormierungsskala auf den Wirkungsquerschnitt hat. / In this thesis we will explore a Mellin space approach to the evaluation of precision cross-sections at hadron colliders. We consider three processes with known analytic results for perturbative QCD corrections up to the next-to-next-to-leading order, namely: the production of vector bosons Z0, W± via the Drell-Yan mechanism in the narrow width approximation; the production of the standard model Higgs boson via gluon-gluon fusion using the large top quark mass limit and the neutral and charged current deep inelastic lepton-hadron scattering. We develop a c++ package sbp that implements the Mellin space technique. The resulting program provides an elegant, fast and accurate solution for the evaluation of inclusive cross sections. We compare our program with available results that use standard momentum space techniques. We present studies of asymptotic convergence and scale dependence of the perturbative series. We use the package to study different treatments of factorisation and renormalisation scales in cross sections.

Representations of sexual practice and identity in men's prisons since the 1950s in the UK and the USRiley, Michael J. January 2014 (has links)
In this thesis I propose that the representation of the prison is an untapped and valuable resource for non-traditional representations of the queered male, homo-sex and sexualities. I draw together texts on prison and sexuality from the 1800s to the 2000s in order to discuss the representation of prison in light of what it adds to a wider historical understanding of sexuality. The thesis is broadly chronological in form, analysing academic and theoretical texts in context alongside popular cultural representations. I reassess the ways in which sexuality is viewed and understood over time, and place homosexuality within the framework of wider male sexuality as represented in the prison. I theorise a re-imagining of homosexuality within normative male sexuality and I challenge the concept of ‘situational sex' through the complex issues behind understandings of sex in prison. My research methodology includes close textual analysis of representations of prison in literature, film and television alongside academic and theoretical texts on sexuality, gender and queer theory. Each chapter focuses on specific cultural texts, including Against the Law (1957), Birdman of Alcatraz (1962) Short Eyes (1977), Scum (1977, 1979) and Oz (1997-2003). By drawing the representations and the theories together I am able to provide a re-reading of the texts within a recognition of sexual fluidity and the reclassification of heterosexual males and gender hierarchies. In my research I argue that the representation of sex in prison re-writes sexuality and contributes to a reading of the queering potential of the cultural representation of prison. With this method I challenge conventional understandings of sexuality as well as perceptions of how male sexuality is viewed in popular culture. I argue that the cultural representation of the prison is a site of queer potentiality in form, idea and context and is a means to re-imagine male sexuality.

Report Writing for Criminal Justice ProfessionalsMiller, Larry S., Whitehead, John T. 01 January 2015 (has links)
The criminal justice process is dependent on accurate documentation. Criminal justice professionals can spend 50-75% of their time writing administrative and research reports. Report Writing for Criminal Justice Professionals, Fifth Edition provides practical guidance--with specific writing samples and guidelines--for providing strong reports. Much of the legal process depends on careful documentation and the crucial information that lies within, but most law enforcement, security, corrections, and probation and parole officers have not had adequate training in how to provide well-written, accurate, brief, and complete reports. Report Writing for Criminal Justice Professionals covers everything officers need to learn--from basic English grammar to the difficult but often-ignored problem of creating documentation that will hold up in court. This new edition is updated to include timely information, including extensive coverage of digital reporting, updates on legal issues and privacy rights, and expanded coverage of forensics and scientific reporting. / https://dc.etsu.edu/etsu_books/1014/thumbnail.jpg

Articulating a Vision: A Case of Study of Democracy, Education, and Prisoner Rehabilitation in a Day Reporting CenterJones, Gregory A 01 June 2014 (has links)
Abstract
Unfortunately, little or no time is spent on transitioning inmates back into society, especially those with physical and mental disabilities. One support service that is being taken into consideration is the Day Reporting Center. Day Reporting Centers are highly structured nonresidential programs. Parolees report to the center on a daily basis, submit to drug tests, and are enrolled in various counseling, education, or vocational classes. Whereas most centers have strict monitoring and surveillance of parolees, one center that stands out in its alternative approach of self-governance is the San Bernardino Day Reporting Center in San Bernardino, California. There, the parolees are allowed to contribute to the running and governance of the Center.
The hypothesis asserts that the positive culture that surrounds the Center provides parolees the opportunity to reconsider, revise, challenge, and change their negative criminal identities, by viewing themselves in a constructive manner to successfully transition back into society. Eight assumptions were used to either support or nullify the hypothesis: spheres of civility; performative spaces; personal social space; weaving theory; opportunity theory; transformation theory; Freirian pedagogical approach; and pelindaba. The data was gathered using multiple sources, such as several interviews with staff and ex-parolees, and observations of daily procedures and classroom instruction and interaction. NVivo 8, a Qualitative Data Analysis software program (QDA), was used to transcribe, code, and organize the interviews into various themes. The comments by staff and parolees demonstrated that the implementation of these assumptions has resulted in a family like environment. This environment has allowed parolees to focus on their identity in a positive, transformative, and rehabilitative manner that is supported by everyone at the Center.

THE IMPACT OF INCARCERATION AND SOCIETAL REINTEGRATION ON MENTAL HEALTHWicks, Veronica 01 June 2017 (has links)
The purpose of this study was to examine ex-offender’s beliefs on the impact of incarceration and societal reintegration on mental health. The study is a qualitative design using interviews that were audio recorded and transcribed for analysis. The study sought to address the relationship between perceptions of mental health and experiences of incarceration and reintegration among formerly incarcerated individuals. The following themes emerged from participant responses: incarceration challenges, mental health stigma, and rehabilitation service accessibility. The findings of this study may contribute to social work practice by providing awareness to the factors impacting ex-offenders’ mental health and interventions needed. The significant importance the findings provide may influence social work advocacy for the services supporting rehabilitative reintegration and may reduce the rate of rearrested offenders, providing overall better mental health resources and services to this population.

A Survey of Probation Officers' Opinions: Risk AssessmentsCanty, Kenika Kiante' 01 January 2015 (has links)
The U. S. criminal justice system has used risk assessment tools in an effort to reduce recidivism and risk assessment tools are now commonplace. Correctional organizations, however, have struggled with officers' resistance to these tools in spite of the evidence for their utility. There is limited research that explores the impact of resistance to organizational change within the context of correctional agencies. To address that gap, this correlational study used organizational change theory to examine officers' resistance to the use of risk assessment tools based on officers' opinions of the risk assessment tool being used in North Carolina. Data were collected through an online survey of 109 North Carolina probation and parole officers. Multiple linear regression analysis was used to examine the statistical relationship between officer use of risk assessment tools and the dependent variables which included officers' opinions of the risk assessment tool, knowledge of risk assessments, training for use of risk assessments, risk assessments in the sentencing process, and officers' length of time employed. Findings indicated that opinions of the risk assessment tool and training to use the tool statistically impact officers' use of the tool in daily supervision of offenders. Organizational change theory predicted these findings as officers' resistance to policy change was manifested in their opinions of that policy. Implications for positive social change include recommendations for corrections agencies to refine training regarding risk assessments in efforts to minimize officer resistance of properly applying risk assessment tools in daily job duties with the intended outcome of reducing recidivism, and therefore preventing future harms to the community.
