Policing the Drunk Driver: Measuring Law Enforcement Involvement in Reducing Alcohol-Impaired DrivingDula, Chris S., Dwyer, William O., LeVerne, Gilbert 10 July 2007 (has links)
Introduction: With many thousands of deaths still annually attributable to driving under the influence (DUI), it remains imperative that we continually address the problem of producing and sustaining effective countermeasures, and that we subject these efforts to empirical scrutiny. This article presents relevant findings from state-wide datasets. Results: A formula generating a potentially useful metric for assessing aspects of the DUI prosecutorial chain is presented, focusing on the rate of proactive DUI arrests. While in need of cautious interpretation due to issues of inherent inaccuracies in large databases, small numbers of crashes and/or arrests in multiple jurisdictions, and the lack of replication in other states, the analyses show no relationship between the level of DUI arrest activity and DUI-related crashes. This finding brings into question the efficacy of the many millions of dollars devoted each year to targeted DUI enforcement, as it is currently being implemented. Conclusions: Results are discussed in terms of developing adequate disincentives to DUI so as to raise general deterrence via dramatic increases in proactive DUI enforcement and then engaging in pervasive and persistent social marketing of such efforts to maximize the perception that arrest and punishment for DUI is always imminent, that penalties will be swift, certain, and severe. It is echoed that accurate data need to be collected at all levels of the DUI arrest and prosecution process in every jurisdiction within a state, so as to facilitate the empirical assessment of countermeasure efficacy in reducing alcohol-related crashes. Impact on Industry: Given that this work needs to be replicated, the impact on the traffic safety industry is potentially huge. The present data indicate that law enforcement efforts to further abate DUI-related crashes are apparently ineffective, though likely necessary to maintain reductions achieved in the 80s and early 90s. Thus, to attain additional systematic reductions, a dramatic increase in enforcement will be necessary as will a diversification of abatement efforts, including an increase in aggressive social marketing tactics to positively impact our traffic safety culture by making DUI universally unacceptable (for a discussion of this latter issue and on the use of positive reinforcement to change driver behavior, see Dula & Geller, 2007).

Waiting Times and DWI, Court-Mandated Treatment CompletionGreen, Cailyn Florence 01 January 2019 (has links)
Drivers under the influence of alcohol cause nearly one third of all fatal motor vehicle accidents. Ambulatory outpatient alcohol abuse treatment has been clinically shown to increase abstinence, which could decrease the chance of subsequent DWI offences. A barrier to successful completion is extended waiting periods prior to treatment engagement. The theory of patient waiting supports the longer a patient waits to begin treatment the lower the likelihood of successful completion. By exploring the impact of waiting times on DWI court mandated clients, referral courts and treatment facilities can work together to create a successful completion strategy for offenders. The research question focused on if days waiting can predict successful outpatient treatment completion in court mandated adults. The TEDS-D archival data set was used, consisting of data collected between 2006-2011 from federally funded substance abuse treatment centers throughout the USA. The variables time awaiting treatment, treatment level, gender, race, employment status, and age were used as controls. A logistic regression using a random sample of 4,947 participants determined days waiting was significant but weak in nature. The variables of employment status and age are stronger predictors of treatment completion. An interaction effect analysis of days waiting and age results in clients over 45 years old being significantly impacted by days waiting while younger clients are not. Court and treatment agencies can use this information to give priority intake appointments to older clients to increase chances of treatment completion.

A Living Nightmare: A Phenomenological Study of Black Males' Lived Experiences of Racial Profiling During Traffic StopsJackson, James C., III 01 January 2018 (has links)
For years, urban communities and specific ethnic groups within the US (mostly Blacks and Hispanics) have been targeted for racial profiling by our local police. Since the 1990’s, the outcry for justice by our Black and Hispanic communities increased the interests to find ways to address and fight against the act of racial profiling. This phenomenological study used a qualitative approach to collect information and gain the understanding and lived experiences of Black males between the ages of 20 – 49 who experienced racial profiling during routine traffic stops. Twelve Black Males between the ages of 20 to 49 were interviewed for the research study. Everyone was interviewed separately to gather experiences and meanings from their own points of view. In addition, 25 Black males within the same age group participated in a 1 hour focus group discussion. The information gathered from the interviews and focus group sessions were compiled into a Microsoft word transcript and reviewed and analyzed by the researcher to form seven themes. In order to come up with key findings, I isolated similar responses from the experiences shared by the research participants during the interviews and focus group session. In isolating some of the key responses revealed, I dissected racial profiling from a shared experience point of view based on common approaches practiced by law enforcement officers. The research study will contribute to field on conflict resolution through the voices of those who experienced racial profiling, and finding ways to encourage mediation through projecting the underlying concerns or issues to community leaders, government officials, concerned groups, and law enforcement agencies.

Improving the sustainability in student housing with digital integrationLundqvist, Max January 2023 (has links)
Sustainability is an important factor in many different industries and the housing industry is not an exception. Especially when the housing is intended for students, more accurately international students which ads on layers of difficulty in regards to sustainability. Ecological, economic and social sustainability becomes increasingly more difficult to achieve when providing housing for international students. Why can be answered in many different ways such as cultural differences, different way of life or just the question regarding the Ac unit or lack of it in Sweden. Akademiska Hus is a industry leading company in Sweden for providing sustainable housing to international students. They constantly work with question regarding sustainability such as how they can make the housing more sustainable as well as keeping all the involved parties in the process happy. They have therefore been researching new ways to approach this question. This master thesis focuses on evaluating a potential improvement regards to sustainability question as well as keeping all the parties involved happy. The focus is on finding how all matters regarding housing can be integrated into one application. The areas investigated is (1) model of integration, (2) the approach for the system integration, and (3) the user experience of the developed application that is tested. The work in the thesis was divided into three parts. The first part was to find out the problems in the housing today and the goals with the application, this included research into the different fields as well as an external analysis. The second part was gathering data by conducting user interviews with the intended users of the application as well as testing the application on them. Data was also collected by analysing the application and how it works in regards to the system itself. Lastly the data was analyzed several times with the double diamond approach. The results showed that an application such as the one tested could greatly improve sustainability in the housing with the most important functions being messaging, community, making error reports and having access to documentation in the library. However, the application needs to be tested more in larger scale in the form of a pilot test to make a more accurate decision to as if it is worth investing in.

Effects of tailored messaging on cell phone use avoidance while driving through highway work zones: Application of the risk perception attitude frameworkPrince Adu gyamfi (16520226) 17 July 2023 (has links)
<p>Cell phone use while driving is one of the commonest distracted driving behaviors that causes fatal crashes, and drivers are more likely to use their cell phones in work zones because of slow-moving traffic. The road safety campaign literature suggests that persuasive messages can positively influence safe driving behaviors leading to a reduction in crashes. Thus, this dissertation, guided by the risk perception attitude (RPA) framework, sought to examine how tailored messaging could serve as an effective communication strategy to promote positive attitudes and behavioral intentions in the context of cell phone use avoidance while driving through highway work zones. Findings from two studies, using a college student sample and a national sample of US young adults between 18 and 24 years old, revealed that the RPA framework likely does not serve as a useful audience segmentation strategy in this context because an overwhelming majority of participants (about 87%) belonged to the responsive group. A tailored messaging approach did not influence cell phone use avoidance while driving attitudes and intentions among the young adults because the majority of participants (70%) felt the messages were not designed uniquely for them and might not be personally relevant to them. However, the majority of participants (62%) reported that highway work zone safety was an important topic they would want to receive future messaging about because messages about this topic would help to save lives and protect public safety, drastically reduce crashes in highway work zones, and promote safe driving behaviors in highway work zones. Participants who were aware of the existence of state laws banning cell phone use while driving reported slightly higher attitudes toward and intentions to engage in safe driving behaviors compared to those who were not aware of the existence of such state laws. This dissertation suggests that instead of creating messages to raise risk perceptions and enhance efficacy perceptions, informing the young adult population in the US about the existence of laws banning cell phone use while driving might be an effective means to discourage them from using their cell phones while driving through highway work zones. By extending the RPA framework as an audience segmentation strategy, this dissertation also proposes a responsive group classification framework which could serve as a useful audience segmentation strategy in this study context to classify audiences into four groups to effectively tailor messages to them.</p>

Enhancing Reading Comprehension Rates: Comparing following along and not following along during Listening-While-Reading Interventions in Middle School and Junior High School Students with DisabilitiesHoskyn, Constance Elizabeth McDaniel 15 December 2007 (has links)
A multielement brief experimental analysis was used to improve and extend previous research to compare the impact of listening while reading while following along (LWFA) and listening while reading while not following along (LWNFA) interventions on oral reading comprehension rate (ORCR), reading comprehension levels, and reading fluency in students with reading disabilities. The collected data for each of the eight middle school and junior high special education students who were participants in this study included: (a) words read correct per minute (WPM), (b) errors per minute (EPM), (c) comprehension questions answered correct per passage, and (d) ORCR. The students ranged from 11 to 14 years of age and 7 of the students were male and 1 was female. Student?s standard intelligence scores, as obtained from student records of formal assessment for eligibility for special education services, ranged from 66-116. All students were functioning at the fourth grade instructional level. Analysis by individual suggest that both listening while reading treatment conditions enhanced oral reading comprehension rates, reading comprehension levels, and increased reading fluency as compared to the control condition. Students displayed higher ORCR, total comprehension questions answered correctly, answered more factual questions correctly, and WPM under LWFA as compared to LWNFA and the control conditions. However, fewer EPM were reported overall for the LWNFA and higher reading comprehension inference questions answered correctly were also observed. Statistically significant differences were noted in reading fluency measures such that more words were read under LWFA as compared to the control condition and fewer errors were reported under LWFA as compared to the control condition. Methodological limitations associated with te current study,individual student performance difference and procedures for using ORCR are described.

Examining strategies for reducing cell phone use while driving: investigating the potential of targeting non-driving participants of cell phone conversations and testing the utility of techniques for reducing habitual responses to cell phonesMiller, Megan Michelle January 1900 (has links)
Doctor of Philosophy / Department of Psychological Sciences / Laura A. Brannon / The current research investigated strategies to reduce cell phone use while driving. Anti-distracted driving campaigns, which typically communicate risk information and target driver behavior, may produce limited effects because people tend to underestimate their risk from this behavior (e.g., Schlehofer et al., 2010). Study 1 compared the effects of messages targeting drivers to messages targeting non-drivers in order to examine the potential of discouraging people from having cell phone communication with others who are driving.
Some anti-distracted driving campaigns have emphasized the potential harm to both the driver and others, but whether one approach (self-oriented or other-oriented messaging) is more persuasive than the other has not been examined empirically. Study 1 compared messages that were self-oriented, other-oriented, or neutral in terms of who could be affected by cell phone use while driving.
Although cell phone use while driving generally is perceived as dangerous, people may make justifications for engaging in the behavior on at least some occasions, and these justifications may override the influence of risk knowledge on behavior. Consistent with inoculation theory (McGuire, 1961), if given the opportunity to practice refuting these justifications in a controlled setting, people will be more likely to defend themselves against justifications to engage in cell phone use while driving. Thus, Study 1 tested the prediction that participation in an inoculation task would reduce the likelihood of cell phone use while driving.
Results from Study 1 suggested an advantage of targeting non-driving participants of cell phone conversations to enhance efforts for reducing on-the-road cell phone use. Study 1 also demonstrated a positive effect of inoculation, but primarily for behavior of non-driving participants of cell phone conversations.
In addition to overconfidence in ability to avoid risk, habitual tendencies also may impede the influence of risk communication campaigns (Bayer & Campbell, 2012). Study 2 investigated the potential of mindfulness-based and implementation intentions techniques for helping people overcome habitual responses to their cell phone when doing so is inappropriate or inconvenient. Results indicated that pairing mindfulness-based training with risk information may be significantly more effective than risk information alone at inhibiting inappropriate cell phone use.

ALTERNATE POWER AND ENERGY STORAGE/REUSE FOR DRILLING RIGS: REDUCED COST AND LOWER EMISSIONS PROVIDE LOWER FOOTPRINT FOR DRILLING OPERATIONSVerma, Ankit 2009 May 1900 (has links)
Diesel engines operating the rig pose the problems of low efficiency and large
amount of emissions. In addition the rig power requirements vary a lot with time and
ongoing operation. Therefore it is in the best interest of operators to research on alternate
drilling energy sources which can make entire drilling process economic and
environmentally friendly. One of the major ways to reduce the footprint of drilling
operations is to provide more efficient power sources for drilling operations. There are
various sources of alternate energy storage/reuse. A quantitative comparison of physical
size and economics shows that rigs powered by the electrical grid can provide lower cost
operations, emit fewer emissions, are quieter, and have a smaller surface footprint than
conventional diesel powered drilling.
This thesis describes a study to evaluate the feasibility of adopting technology to
reduce the size of the power generating equipment on drilling rigs and to provide ?peak
shaving? energy through the new energy generating and energy storage devices such as
flywheels. An energy audit was conducted on a new generation light weight Huisman LOC
250 rig drilling in South Texas to gather comprehensive time stamped drilling data. A
study of emissions while drilling operation was also conducted during the audit. The
data was analyzed using MATLAB and compared to a theoretical energy audit. The
study showed that it is possible to remove peaks of rig power requirement by a flywheel
kinetic energy recovery and storage (KERS) system and that linking to the electrical grid
would supply sufficient power to operate the rig normally. Both the link to the grid and
the KERS system would fit within a standard ISO container.
A cost benefit analysis of the containerized system to transfer grid power to a rig,
coupled with the KERS indicated that such a design had the potential to save more than
$10,000 per week of drilling operations with significantly lower emissions, quieter
operation, and smaller size well pad.

[en] TRANSIENT MODELING OF HORIZONTAL AND NEAR HORIZONTAL FOR WELLBORE DRILLING / [pt] MODELAGEM PARA O ESCOAMENTO TRANSIENTE HORIZONTAL E QUASE HORIZONTAL NA PERFURAÇÃO DE POÇOS DE PETRÓLEOSUZANA SANTOS COSTA 22 August 2006 (has links)
[pt] Dentre os custos considerados na explotação de um campo de
petróleo, os
de perfuração constituem uma parcela significativa do
total. Dentro deste
cenário, devemos estar atentos à remoção dos cascalhos
gerados pela
perfuração, também referido como limpeza de poços. Esta
operação é, ainda
hoje, um tema crítico na perfuração de poços de alta
inclinação, pois os
cascalhos que se depositam devido à ação da gravidade,
formam um leito no
interior do espaço anular formado entre a coluna de
perfuração e o revestimento.
Quando este leito ocupa grande parte do espaço anular, ele
é responsável por
diversos problemas na perfuração, como por exemplo,
desgaste prematuro da
broca, baixas taxas de penetração, fraturamento da
formação, torques e arrastes
excessivos na coluna de perfuração, prisão da coluna de
perfuração, interrupção
da circulação de fluido, aumento da pressão no anular,
etc. Se esta situação não
for tratada adequadamente, o problema pode provocar a
perda do poço. A tese
propõe uma modelagem para o escoamento multifásico na
perfuração de poços
de petróleo, capaz de avaliar a formação do leito de
cascalhos e prever
oscilações de pressões no anular decorrentes do
escoamento. O modelo
adotado é o de duas camadas, onde o espaço anular é
dividido em duas regiões:
leito e suspensão. O leito (Região 1) é formado pelos
cascalhos que se
sedimentam devido ao efeito gravitacional enquanto a
suspensão (Região 2) é a
porção do anular acima do leito depositado, formada pelo
fluido de perfuração e
os cascalhos transportados. As equações que constituem o
modelo
implementado são dadas pelas equações de conservação de
massa para os
sólidos e para o líquido e as equações de conservação de
quantidade de
movimento para o leito e para a suspensão. O método dos
volumes finitos foi
utilizado para a discretização das equações diferenciais
juntamente com o
método de Newton para a solução do sistema não-linear de
equações. A
solução é dada através das seguintes variáveis: altura do
leito, velocidade dos
sólidos no leito e na suspensão, velocidade do fluido no
leito e na suspensão, pressão no anular e concentração de
sólidos no anular. Exemplos de aplicação
da metodologia são apresentados e mostram o comportamento
das variáveis
envolvidas ao longo do tempo. Os exemplos mostram a
eficácia da metodologia
para simular operações de perfuração, em especial, a
limpeza de poço. / [en] Among the costs considered on an oil field exploration,
the drilling process
related ones constitute a significant share. Consequently,
the focus on the
removal of cuttings generated by the drilling process, or
the hole cleaning
operation, is essential. This operation remains a critical
issue in the drilling of
high inclination-wells, since the cuttings tend to deposit
themselves due to
gravity´s action, forming a bed in the annular space
formed between the drill
string and the casing. When this bed takes a sizable
fraction of the annular
space, it becomes responsible for many problems that
appear on the drilling
stage, such as premature bit´s exhaustion, low rates of
penetration, formation
fracture, excessive torque and drag on the drillstring,
stuck pipe, fluid flow
interruption, etc. If this situation is not treated
properly, it may cause the loss of
the well. This present thesis proposes a model for
multiphase flow in the
wellbore drilling, capable of evaluating the formation of
the cuttings´ bed and to
predict oscillations of pressures in annulus due to the
flow. A two-layer model is
adopted, where the annular space is divided in two
regions: bed and suspension.
The bed (Region 1) is formed by the cuttings, which were
deposited due to the
action of gravitational force, while the suspension
(Region 2) is the portion of the
annular above the deposited bed, formed by the drilling
fluid and cuttings. The
constitutive equations of the aforementioned model are
given by the equations of
mass conservation for solids and liquids and the momentum
conservation
equations for the bed and the suspension. The finite
volumes method was used
to turn the differentials equations into discrete ones,
while the Newton´s method
was applied for the solution of the nonlinear system of
equations. The solution is
given through the following variables: bed height, solid
velocity and fluid velocity
both in bed and suspension, annular pressure and solid
concentration in the
annular. Examples of application of the methodology are
presented, showing the
behavior of the involved variables through time. The
examples show the efficacy
of the methodology to simulate drilling operations, in
special hole cleaning ones.
