This thesis work has been conducted in the Handheld Laboratory at Husqvarna AB with the purpose of finding the parameters responsible for the performance of the catalytic converters used in the test rig. The catalytic converters are used in the test rig during the long term testing of the chain saws to reduce the hydrocarbon content from the exhaust before it enters into the environment. To perform this research two approaches were carried out. One with Design of Experiment (DOE) and another using Scanning Electron Microscope (SEM) analysis. In Design of Experiments parameters that are suspected to be influencing the performance of the catalytic converter were refined. Using these parameters a test plan is made with the help of statistical analysis application Minitab and the tests were carried out in the test rig. Using SEM the effects of aging and its effect on microstructure and chemical composition on the catalyst surface was analyzed. The results from the DoE shows that the exhaust flow, collector diameter and distance to the muffler are responsible for the collection of exhaust. Distance to the muffler and collector length are the factors affecting the conversion of the exhaust. In addition to that exhaust flow is also responsible for the duration of heating coil running time. The results from the SEM analysis shows that the operating temperature is high due to which there is thermal degradation of catalyst and there is also deactivation due to fouling. Another finding is that the flow on to the catalyst is not uniformly distributed

Full textAbstract:
Abstract The presumed dominance of the traditional annual budgeting process as a cornerstone of management control has been called into question in recent years. Various new developments in budgeting have been seen replacing or complementing organisations’ conventional budgeting. The dissertation provides a comprehensive picture of these new budgetary practices and their implications for management accounting work, through investigation of the fragmentation among various purposes of budgeting and of the ways in which the role of controller and new budgetary practices can complement each other. The dissertation is composed of four inter-related essays, which provide qualitative evidence of how firmly established practices such as budgeting change and what implications the change has for the conflicting purposes of budgeting. It also provides insight into the ways controllers are able to build holistic view of the totality of budgetary control and compile new accounting information. The empirical findings presented in the dissertation give rise to novel concept of fragmentation, which can be defined as an arrangement wherein a new mix of diverse controls is used to serve several purposes of budgeting and a single budgeting process is either replaced with or complemented by other control mechanisms. Fragmentation can serve as a common denominator for recent developments in budgeting but also aid in understanding the variation in new budgetary practices. Fragmentation of budgeting makes the boundaries of a budgetary system blurred but also enables designing flexibility into the control system itself. For the role of controller, fragmented budgetary practices mean co-ordinating the linkages between various budget-related methods, wider communication and interaction with organisational actors, new business-oriented skills related to key purposes of budgeting, and a growing professional role in increasing the ‘realism’ of accounting information in the lateral budgetary planning processTiivistelmä Perinteisen vuosibudjetoinnin valta-asemaa johdon ohjausjärjestelmien kulmakivenä on alettu kyseenalaistaa viime vuosina. Budjetoinnin uudet kehityssuuntaukset näyttäisivät joko korvaavan tai täydentävän vakiintunutta budjetointikäytäntöä organisaatioissa. Tämä väitöskirja tarjoaa kokonaisvaltaisen kuvan uusista käytännöistä, sekä niiden vaikutuksista johdon laskentatoimen työhön. Väitöskirja tutkii budjetoinnin eri tehtävien pirstaloitumista sekä sitä, miten controllerin rooli ja uudet budjetointikäytännöt voivat toimia toisiaan täydentävästi. Väitöskirja muodostuu neljästä toisiinsa liittyvästä esseestä, jotka tuovat laadullisen tutkimuksen keinoin esille, kuinka vakiintunut käytäntö, kuten budjetointi, muuttuu, ja mitä vaikutuksia tällä muutoksella on budjetoinnin eri tehtäviin. Tutkimus tarjoaa myös käsityksen siitä, miten kontrollerit muodostavat kokonaiskuvan budjetoinnillisesta ohjausjärjestelmästä ja tuottavat uutta laskentatoimen informaatiota. Tämä väitöskirja kuvaa budjetoinnin muutosta käsitteellä pirstaloituminen (fragmentation). Se voidaan määritellä järjestelyksi, jossa uutta, erilaisten ohjausmenetelmien yhdistelmää käytetään palvelemaan budjetoinnin eri tehtäviä, ja jossa yksittäinen budjetointiprosessi joko korvautuu tai täydentyy muilla ohjausmekanismeilla. Tämä käsite tarjoaa yhteisen nimittäjän viimeaikaisille budjetoinnin kehityssuuntauksille, mutta auttaa myös ymmärtämään paremmin budjetoinnin eri variaatioita. Budjetoinnin pirstaloituminen hämärtää budjetointijärjestelmän rajat, mutta mahdollistaa myös joustavuuden suunnittelun järjestelmään itsessään. Kontrollerin roolin näkökulmasta budjetoinnin pirstaloituminen merkitsee budjetoinnin eri menetelmien välisten yhteyksien koordinointia, laajempaa kommunikaatiota ja vuorovaikutusta organisaation eri toimijoiden kanssa, uusien liiketoimintaorientoituneiden taitojen lisääntymistä sekä ammatillisen roolin korostumista laskentainformaation realismin parantamisessa budjetoinnin lateraalisessa suunnitteluprosessissa

Full textAbstract:
Although upper limb motor impairments are common, the primary tools for assessing and tracking these impairments in a clinical setting are subjective, qualitative rating scales that lack resolution and repeatability. Markerless motion capture technology has the potential to greatly improve clinical assessment by providing quick, low-cost, and accurate tools to objectively quantify motor deficits. Here we lay some of the groundwork necessary to enable markerless motion capture systems to be used in clinical settings. First, we adapted five motor tests common in clinical assessments so they can be administered via markerless motion capture. We implemented these modified tests using a particular motion capture sensor (Leap MotionTM Controller, hereafter referred to as the Leap Motion sensor) and administered the tests to 100 healthy subjects to evaluate the feasibility of administrating these tests via markerless motion capture. Second, to determine the ability of the Leap Motion sensor to accurately measure tremor, we characterized the frequency response of the Leap Motion sensor. During the administration of the five modified motor tests on 100 healthy subjects, the subjects had little trouble interfacing with the Leap Motion sensor and graphical user interface, performing the tasks with ease. The Leap Motion sensor maintained an average sampling rate above 106 Hz across all subjects during each of the five tests. The rate of adverse events caused by the Leap Motion sensor (mainly jumps in time or space) was generally below 1%. In characterizing the frequency response of the Leap Motion sensor, we found its bandwidth to vary between 1.7 and 5.5 Hz for actual tremor amplitudes above 1.5 mm, with larger bandwidth for larger amplitudes. To improve the accuracy of tremor measurements, we provide the magnitude ratios that can be used to estimate the actual amplitude of the oscillations from the measurements by the Leap Motion sensor. These results suggest that markerless motion capture systems are on the verge of becoming suitable for routine clinical use, but more work is necessary to further improve the motor tests before they can be administered via markerless motion capture with sufficient robustness for clinical settings.

Full textAbstract:
A fast and efficient method to calculate time schedules for internal and boundary PRVs and flow modulation curves has been developed and implemented. Both time and flow modulation can be applied to a single inlet DMA. The time modulation methodology is based on solving a nonlinear programming problem (NLP). In addition, Genetic Algorithms (GA) has been proposed and investigated to calculate the optimal coefficients of a second order relationship between the flow and the outlet pressure for a PRV to minimize the background leakage. The obtained curve can be subsequently implemented using a flow modulation controller in a feedback control scheme. The Aquai-Mod® is a hydraulic device to control and modulate the outlet pressure of a PRV according to the valve flow. The controller was experimentally tested to assess its performance and functionality in different conditions and operating ranges. The mathematical model of the controller has been developed and solved, in both steady state and dynamic conditions. The results of the model have been compared with the experimental data and showed a good agreement in the magnitude and trends. A new method for combined energy and pressure management via integration and coordination of pump scheduling with pressure control aspects has been created. The method is based on formulating and solving an optimisation NLP problem and involves pressure dependent leakage. The cost function of the optimisation problem represents the total cost of water treatment and pumping energy. Developed network scheduling algorithm consists of two stages. The first stage involves solving a continuous problem, where operation of each pump is described by continuous variable. Subsequently, the second stage continuous pump schedules are discretised using heuristic algorithm. Another area of research has been developing optimal feedback rules using GA to control the operation of pump stations. Each pump station has a rule described by two water levels in a downstream reservoir and a value of pump speed for each tariff period. The lower and upper water switching levels of the downstream reservoir correspond to the pump being “ON” or “OFF”. The achieved similar energy cost per 1 Ml of pumped water. In the considered case study, the optimal feedback rules had advantage of small number of ON/OFF switches, which increase the pump stations lifetime and reduce the maintenance cost as well.

Full textAbstract:
Adult marijuana users seeking treatment (N = 291) were randomly assigned to 3 treatment conditions: 1) a cognitive-behavioral relapse prevention support group (RPSG), 2) individualized assessment and advice group, and 3) delayed treatment control group. The purpose of this study was to investigate the role of self-efficacy in goal setting and treatment outcomes based on self-stated goals (abstinence or moderation) for marijuana use. Measures of marijuana use, treatment goal, and self-efficacy for achieving oneâ s goal were used. Goal choice was shown to influence treatment outcome such that, participants were more likely to achieve outcomes consistent with their treatment goal. The findings suggest that self-efficacy for goal achievement is more strongly related to outcomes for those with abstinence treatment goals, but appears to exert some effect across both goal types.Master of Science

Feedforward self-modeling (FF-SM), the process of viewing an edited video of the self- performing above one’s current ability (Dowrick, 1999), has been shown to be an effective tool for enhancing athletes’ competitive performance (Ste-Marie, Rymal, Vertes, & Martini, 2011). At 3 consecutive competitions, 9 trampolinists aged 9-16 years old were provided a FF-SM video of their trampoline routine one hour prior to competing and were provided the opportunity to control their viewings at their leisure. On average, the trampolinists viewed their videos 5 times per competition at 2 different time intervals. Interviews revealed that they perceived the video enhanced their performance. They indicated they chose to watch it to assist with skill execution; although, self-reported outcomes did include increased motor execution, increased self-efficacy, use of task strategies, and adaptive inferences. Throughout the span of the intervention, the trampolinists reported changes in their use of imagery, self-talk, and self-observation.

Full textAbstract:
Lastly, the 250-MHz antenna provided better resolution of the burial scenarios than the 500-MHz antenna due to easier discrimination of the forensic targets. Therefore, the use of a 250-MHz antenna would be a viable option to search for clandestine burials containing adult-sized bodies.; The use of geophysical tools to locate clandestine burials involving bodies has seen increasing popularity among forensic personnel. Often, these search methods are important to highlight certain areas where a body may or may not be located prior to utilizing invasive search techniques. Because of the success of these tools within real-life forensic searches, the use of controlled studies that monitor and detect cadavers over certain lengths of time have been increasingly utilized. However, these controlled studies have not monitored various burial scenarios that mimic real-life situations. This study focused on detecting and monitoring six burials containing pig carcasses used as proxies for human bodies and two control burials with a conductivity meter and ground-penetrating radar (GPR) with a 500-MHz and a 250-MHz antenna over a twelve month period. Each burial within this study represented a different forensic scenario that mimicked a real-life situation. Further, forensic use of GPR in both controlled settings as well as real-life searches have mainly focused on the use of a 500-MHz antenna. Therefore, this research also compared the use of a 250-MHz antenna with a 500-MHz antenna. Lastly, a number of GPR imagery options were utilized including reflection profiles and horizontal slices with various GPR software programs to compare the results obtained. Results obtained from the conductivity meter were compared to the results obtained by both antennae of the GPR. Overall, the use of multiple GPR imagery options provided increased resolution of the burial scenarios. Results showed that the conductivity meter was not a beneficial geophysical tool because none of the burial scenarios were detected. On the other hand, the use of GPR showed that the graves with objects added to the pig carcasses provided increased resolution compared to the graves containing only pig carcasses.ID: 028916825; System requirements: World Wide Web browser and PDF reader.; Mode of access: World Wide Web.; Thesis (M.A.)--University of Central Florida, 2010.; Includes bibliographical references (p. 180-182).

Full textAbstract:
A revisão judicial, desde sua criação, se tornou alvo de diversas críticas principalmente no que se refere a sua necessidade por representar o empoderamento do poder judiciário que passa a ter a prerrogativa de retirar do ordenamento jurídico qualquer norma que supostamente esteja afrontando a constituição, tudo com base no discurso de proteção dos direitos fundamentais e de evitar uma tirania da maioria. Apesar de polêmico, esse instituto é defendido pelos filósofos jurídicos e questionado pelos filósofos políticos, dentre eles, Jeremy Waldron, o qual repudia a utilização da revisão judicial por afrontar a igualdade dos cidadãos que deveriam por si, ou através dos seus representantes, discutir e solucionar os desacordos. No Brasil, o controle concreto de constitucionalidade retrata bem o empoderamento do poder judiciário, uma vez que a emenda constitucional n. 45/2004 criou o filtro da repercussão geral regulamentado posteriormente em 2006, o qual limita a apreciação dos recursos com base em conceitos jurídicos indeterminados, possibilitando a escolha pelo Supremo Tribunal Federal dos recursos que serão julgados. Essa possibilidade de escolha pode ser explicada pela teoria do agendamento (agenda-setting), que prevê a hipótese de alteração da agenda política a partir da transferência de saliência da agenda do público. Assim, foram aplicadas tais teorias ao controle concreto brasileiro, no intuito de identificar no comportamento do Supremo Tribunal Federal a existência de um comportamento seletivo em relação aos processos, bem como verificar quais assuntos tendem a ter sua repercussão geral reconhecida, verificando-se por fim se esse tipo de revisão judicial atende aos aspectos justificadores de proteção dos direitos fundamentais e prevenção de uma tirania da maioria. Para tanto, foi elaborado um banco de dados com todos os recursos que tiveram a repercussão geral reconhecida desde 2006, ao qual se aplicou o método da estatística descritiva, comprovando-se a seletividade do tribunal no que se refere a apreciação dos recursos, e ainda verificando-se a tendência do tribunal de reconhecer a repercussão geral dos processos que ensejem algum tipo de impacto orçamentário, tornando o Supremo Tribunal Federal quase um filtro de despesas dos entes governamentais, e sugerindo o descompromisso da corte com a proteção dos direitos fundamentais, ao menos nesse tipo de revisão judicial.The judicial review was criticized since it was created on the grounds that represent an empowerment of the judiciary in comparison to other government institutions, especially regarding the exercise of the power to remove from the law any rule that "supposedly" is defying the constitution, on the basis of fundamental rights protection and with the scope to prevent a tyranny of the majority. The judicial review is defended by legal philosophers and questioned by political philosophers, among them, Jeremy Waldron, which rejects the use of judicial review arguing the equality of citizens that should, by themselves or through their representatives, discuss and resolve disagreements. In Brazil, the concrete judicial review portrays the empowerment of the judiciary, since the constitutional amendment n. 45/2004 created a filter of general repercussion subsequently regulated in 2006, gives the Brazilian Supreme Court the power to select which cases will be analyzed through the appeals. These choices can be explained by agenda-setting theory, which provides hypothesis of explanation of any changes in the political agenda from its suitability to the agenda of its recipients. Thus, we applied these theories to the Brazilian judicial review in order to identify the existence of a selective behavior in Brazilian Supreme Court towards the procedure of case selection (repercussão geral) and saw which subjects tended to be accepted by the court, verifying finally if this kind of selection bias seeks to the protection of fundamental rights and the tyranny of the majoritys prevention. Therefore, we designed a database with all the appeals that had the repercussão geral recognized since 2006, and used descriptive statistics to confirm the court's selectivity and to check the tendency of the court to recognize the general implications of the processes that result some kind of budgetary impact, making the Supreme Court almost a filter for of government agencies future expenses, and showing a lack of commitment to the protection of fundamental rights.

Full textAbstract:
Searching for buried metallic evidence at crime scenes or at potential disposal sites can be a daunting task for forensic personnel. In particular, it is common to search for a small firearm that was discarded or buried by the perpetrator. When performing forensic searches, it is recommended to first use non-invasive methods such as geophysical instruments to minimize damage to evidence and to the crime scene. Geophysical tools are used to pinpoint small areas of interest across a scene that will be invasively tested later. Prior to this project, there was no published research that tested the utility of the conductivity meter to search for metallic weapons such as firearms and blunt or sharp edged weapons. A sample comprised of 32 metallic weapons was buried in a controlled setting to test the applicability of a conductivity meter for forensic searches. Weapons were tested at multiple depths; once data collection was performed for one depth, the weapons were reburied 5cm deeper until they were no longer detected. Results obtained with conductivity meter were compared to results obtained by the ground-penetrating radar using different depths and transect intervals. The effects of several variables on detection such as weapon size, metallic composition, burial depth, and transect interval were analyzed in order to explore the limitations of each instrument. Results obtained from this controlled research can provide guidelines to help law enforcement in real-world searches.M.A.

MacLaren, Alister G. "A randomised controlled trial comparing two models of medication review in older patients in a community pharmacy setting." Thesis, University of Greenwich, 2008. http://gala.gre.ac.uk/8316/.
Full textAbstract:
A randomised controlled trial design was chosen to compare a model of community pharmacy based clinical medication review (CMR) with no access to information from patients’ medical records (active) with a model which had access to information from patients’ medical records (control). Four hundred and eighty patients registered with 20 general practitioner (GP) practices received their allocated intervention across 16 pharmacies. There were no statistically significant differences between the groups for the two primary outcome measures used, with 1.7 and 1.9 clinical drug therapy problems (cDTPs) identified at baseline and a cDTP resolution at follow up of 61% and 57% for the active and control groups respectively. There were no significant differences between the groups in the three secondary outcome measures of GP agreement, change in number of repeat medicines and change in utilisation of healthcare services. The cost effectiveness of the two models was compared with the active group found to have a lower cost per cDTP resolved compared with the control group (£46 v £67). Thirty three patients participated in four focus groups with views expressed under the themes of change, empowerment and relationships. Fifteen pharmacists participated in two focus groups and expressed views under the themes of confidence, communication, logistics and empowerment. The hypothesis was accepted such that ‘community pharmacy based CMR of older patients (= 65 years) receiving multiple repeat medicines (= 4) identified and resolved clinical drug therapy problems irrespective of access to information from patients’ medical records’. Both models were well received by patients and practitioners.

Full textAbstract:
The overall aim of this thesis was to examine beliefs about human papillomavirus (HPV) prevention, especially vaccination, among parents, immigrant women, adolescents and school nurses, and to promote primary prevention among adolescents. The methods used in the thesis were focus group interviews, individual interviews, a web-based questionnaire, and finally, a randomised controlled intervention study. The immigrant women were largely in favour of HPV prevention, although barriers, such as logistic difficulties, and cultural or gender norms were found. Parents’ decision concerning vaccination of their daughters depended on several factors. Regardless of their final choice, they made the decision they believed was in the best interest of their daughter. The benefits outweighed the risks for parents choosing to vaccinate while parents declining made the opposite judgement. The majority of the school nurses reported that the governmental financial support given because of the vaccination programme had not been used for the intended purpose. Three out of four nurses had been contacted by parents who raised questions regarding the vaccine; most were related to side effects. The educational intervention had favourable effects on the adolescents’ beliefs regarding HPV prevention, especially among those with an immigrant background. Furthermore, the intention to use condom as well as actual vaccination rates among girls was slightly increased by the intervention. Trust in the governmental recommendations and the amounts of information given are important factors in the complex decision about HPV vaccination. Attention given to specific needs and cultural norms, as well as the possibility to discuss HPV vaccination with the school nurse and provision of extra vaccination opportunities at a later time are all strategies that might facilitate participation in the school-based HPV vaccination programme. School nurses need sufficient resources, knowledge and time to meet parents’ questions and concerns. The vaccinations are time-consuming and the governmental financial support needs to be used as intended, for managing the vaccination programme. A school-based intervention can have favourable effects on the beliefs and actual actions of young people and may possibly thus, in the long term, decrease the risk for HPV-related cancer.

The purpose of this study was to evaluate the effectiveness of teaching self-instructional skills to navigate to a mobile device to access video prompts to teach novel behaviors to two adults with autism spectrum disorder (ASD) in a vocational setting. This study used a multiple probe across conditions design to evaluate effectiveness. In baseline, the researcher directed the participants to complete a novel task and collected data on correct steps completed. In technology training the researcher used a system of least prompts procedure to teach participants to initiate the use of the mobile device, navigate to an app, navigate to the specific behavior schedule, watch video prompt, navigate to the next step, and complete the modeled behaviors. After mastery of technology training, researcher evaluated performance of novel tasks following self-instruction to access video prompts on the mobile device. Participant’s fidelity of navigation skills was assessed, however was not included in mastery criterion. Both participants learned to self-instruct to independently access video prompts on a mobile device. One participant self-instructed using the mobile device and video prompts to correctly complete novel tasks.

Full textAbstract:
Populations in developed and developing countries are becoming increasingly sedentary and the adverse health effects of relatively sedentary lifestyles, the so called lifestyle diseases, are now obvious. However, moderately vigorous physical activity is positively linked via a cause-and-effect relationship with a range of improved health outcomes. Broadly, current physical activity recommendations suggest that adults should achieve a total of at least 30 minutes a day of at least moderate intensity physical activity on five or more days of the week; however, estimates suggest that the majority of adults in the Western World do not meet these recommendations. Many of the factors involved in the initiation and long-term maintenance of physical activity are not fully understood. Considering the rapid pace of technological development and the general move away from labour-based economies, it does appear that the required level of physical activity necessary for optimal health needs to come from leisure-time activity– specifically, planned, regular, moderately vigorous exercise and/or sport. Unfortunately, many people experience great difficulty in engaging with and maintaining a physically active lifestyle and typically there is a rather large gap between what people know to be healthy and what they actually do.
The general aim of this project was to design, implement and evaluate the clinical, social and behavioural effectiveness of a buddy-Motivational Interviewing intervention (buddy-MI) in assisting relatively sedentary adults to adopt and maintain regular physical activity for the purpose of improving their cardio-respiratory fitness, health, and quality of life. Specific aims of the intervention included formally involving social support (via the self-selected motivational-buddy) and strengthening individuals’ motivation for and movement toward their physical activity goals. The experimental intervention specifically aimed to extend the MI treatment effect by enhancing participants’ commitment to physical activity over time via intra-treatment social support (support provided within treatment sessions) as well as extra-treatment social support (day-to-day support) provided by the motivational-buddy. A fundamental was to deliver the intervention in a format that could realistically be implemented within typical primary care settings, workplaces, schools or other similar setting: to work towards healthier more active communities and to potentially reduce health system resource utilisation.
Using a repeated-measures pragmatic parallel group randomised controlled trial (RCT) design, relatively sedentary adolescents and adults, in stable health, recruited from a university campus population were allocated to one of two interventions. In the experimental intervention, participants were supported by a self-selected motivational-buddy and they received 2-4 sessions of buddy-MI over a period of 12-months (participant determined schedule) as well as pro-active follow-up emails. The control intervention was standard care MI, and the same email follow-up as in the experimental group but without the additional support of a motivational-buddy. The main outcomes were self-reported physical activity, cardio-respiratory fitness and health related quality of life. These primary outcomes were measured at four time-points over the 12-months intervention and follow-up period and quantitative methods were used to analyse the data. Qualitative data were also analysed and presented in relation to the motivational-buddy component of the intervention. The study evaluated the feasibility and incremental effectiveness of motivational-buddy support compared to one-on-one MI in people who had expressed an interest in becoming more physically active. It used a novel intervention design incorporating self-selected motivational-buddies in an effort to mitigate the twin problems of poor adherence and behavioural regression that are commonly associated with physical activity promotion programmes. The intervention was found to have merit and the potential implications for the health-care system, and the wider community, are discussed.

Full textAbstract:
Background: Inpatient psychiatric care is a scarce and expensive resource in the National Health Service (NHS), with chronic bed shortages being partly driven by high re-admission rates. People often need to go into hospital when they have a mental health crisis due to overwhelming distressing psychotic symptoms, such as hearing voices (hallucinations) or experiencing unusual beliefs (delusions). Brief talking therapies may be helpful for people during an acute inpatient admission as an adjunct to medication in reducing re-admission rates, and despite promising findings from trials in the USA, there have not yet been any clinical trials on this kind of intervention within NHS settings. Objectives: The primary objective of the study was to find out whether it was possible to carry out this kind of trial successfully within UK inpatient settings in terms of successfully recruiting and retaining patients in the trial. The secondary objective was to collect pilot data on clinical outcome measures, including re-admission rates at 6-month follow-up. Method: The amBITION study (BrIef Talking therapIes ON wards; ISRCTN376253384) was a parallel groups, feasibility randomised controlled trial (RCT) of a manualised brief talking therapy (Mindfulness-Based Crisis Intervention; MBCI). Inpatients on acute psychiatric wards were eligible for the study if they reported at least one positive psychotic symptom, and were willing and able to engage in a talking therapy. In addition to treatment as usual (TAU), participants were randomly allocated to receive either MBCI or a control intervention (Social Activity Therapy; SAT) which involved doing activities on the ward with the therapist. Results: Fifty participants were recruited to the trial (26 MBCI; 24 TAU). No participants dropped-out during the therapy phase, and everyone in the trial received at least one therapy session. The average number of sessions per participant was 3 in both arms of the trial. Retention in the trial was excellent, and exceeded the pre-set benchmark of no more than 20% loss to follow-up at trial end-point (6-month follow-up after discharge). The follow-up rate at 6-month follow-up was 98% for service use data extracted from clinical notes, and 86% for self-report questionnaire measures. Three participants experienced adverse events, but none of these were considered to be related to their participation in the trial. Conclusions: It is feasible to recruit and retain participants in the trial. The therapy was acceptable to patients, and satisfaction ratings with therapy was high. Progression to a further trial is warranted based on these encouraging feasibility outcomes.

Full textAbstract:
State of Objectives: This paper addresses the question of how the presumption-rent system has developed during ten years of its introduction to the rental market, with a particular emphasis on the investors’ perspective. The study has three focus areas, firstly an emphasis on how the real estate investors within the private and public sectors reacted to the introduction of the presumption-rents. Secondly, it examines whether the trends have changed during the course of these ten years. Finally, it observes how the presumption-rent system, as a rent-setting method for new residential rental constructions, is perceived and evaluated by the investors. Methodology: The empirical study focuses on the rent market in Stockholm, and it is articulated through a holistic multiple case-study of six public-and private real estate companies with rental dwellings in Stockholm. In order to examine the developments of the presumption-rent structures in these companies, a numerical analysis of the rent structures through a quasi-experimental design is as well conducted. Empirical Findings: The results in general prove that the rent-setting within the presumption rent system is unpredictable and subjective, because it is influenced by conflicting interests and different perceptions. The implication of this for the application of the presumption-rents is that it is depended on a complex, ambiguous and vague negotiation structure, rather than being based on a systematized rent-setting procedure. Furthermore, it is noted that the collective bargaining system, which sets the standards for the rent negotiations, is undergoing a slow process of change, as the law amendment in 2011 has caused paradigm-shits within the rental market. One dimension of this is that the rent-negotiations noticeably do not influence the investment decisions anymore, but the rent negotiations certainly have an impact on the rent-setting method. The implication for the application of the presumption-rentsystem, including its negotiation framework, is that it is applied when it meets the criteria for the investment decision, otherwise it is ignored. Finally, it is showed that nor the public neither the private companies perceive the presumption-system as a long-term and sustainable solution to the prevailing challenges with the Swedish rent-setting system. What is clear is that the system is mainly considered as a temporality solution to a course of disorders that have emerged from prolonged institutional negligence and error that have impaired the rental markets.

Full textAbstract:
Impact evaluations in development interventions has been growing in recent years. The increasing demand for evidence-based outcomes has led to a debate of what methodology is best to evaluate the impact of development interventions. Accordingly, Randomised Controlled Trial (RCT) has been labeled as a gold standard for impact evaluations. The RCT method functions in a unique way, as it removes the selection bias and ensure high validity of a study. The aim of this research study is to critically assess the RCT as an alternative approach for impact assessment in relation to post-conflict countries; whether this claim holds in a conflict-affected environment or that the context-specific factors of post-conflict countries challenge the implementation of an RCT. This study implements mixed method approach by using simple descriptive statistics and semi-structured interview to answer the research questions. The findings of this study indicate that context-specific factors of post-conflict environments pose challenges on the implementation of an RCT. As a result, these challenges threaten the quality of the RCT method which lies in reliability, internal validity and external validity. The findings also indicate that feasibility of RCT which lies in ethics, logistics and security, cannot be addressed individually, as the feasibility has a direct impact on the quality of the RCT method.

Full textAbstract:
The role that dental team members can play in the smoking cessation field is largely unevaluated. The work of this PhD thesis encompasses two phases, the first was to develop a means of determining smoking status, using analysis of continine, a nicotine metabolite. The second phase looked at the efficacy of dental hygienist-delivered smoking cessation advice in a dental setting. The aim of the first study was to compare continue levels in different biological fluids collected from both smokers and non-smokers, and to relate the findings to self-reported smoking status. Patients recruited to the study were asked to provide samples of urine, blood and saliva (both stimulated and unstimulated). Data collected from patients by questionnaire included information on smoking behaviour, such as daily number of cigarettes smoked, and environmental exposure to smoke. Following sample collection, patients were asked to rate the acceptability of each sampling method. Samples were analysed using enzyme immunoassay (EIA) kits. In total, 80 patients participated, with 49 smokers and 31 non-smokers. There was clear differentiation between smokers and non-smokers (p<0.001) for all the different samples in terms of cotinine concentration. A significant relationship was seen between cotinine levels and daily number of cigarettes for both salivas and urine (all p < 0.001) but not for serum. Participants found serum and urine collection methodologies 'very acceptable' (67% and 66%, respectively) whereas 9% found collection of stimulated saliva 'not at all acceptable'. Thus, continine, as analysed by EIA kits, whatever the collection method, shows good differentiation between smokers and non-smokers. Salivary samples have the advantage of being non-invasive. However, collection methodology is important, as continine levels may vary.

Compton, Dickinson Stella J. "A feasibility trial of group cognitive analytic music therapy in secure hospital settings." Thesis, Anglia Ruskin University, 2014. http://arro.anglia.ac.uk/581523/.
Full textAbstract:
There are no large-scale outcome studies of music therapy in secure hospital settings for people who have committed serious offences. These patients have a right to expect evidence-based multi-disciplinary treatment (Duggan et al. 2006); NICE (2010). Music therapy therefore should take a form which can be integrated into the treatment pathway. A single site implementation of a mixed-methods patient preference randomised controlled trial investigated the clinical effectiveness of a manualised music therapy model called Group Cognitive Analytic Music Therapy (G-CAMT). This context-specific, time limited intervention incorporates theories from Group Analysis (Foulkes 1964) and Cognitive Analytic Therapy (Ryle and Kerr 2003). The central research question was ‘Is G-CAMT feasible and effective for offenders in a secure multi-disciplinary treatment setting?’ The research process followed the Medical Research Council framework for developing and evaluating complex interventions (Campbell et al. 2000, 2007). Twenty patients were recruited; those expressing no preference were randomised to treatment or control arms. The two music therapists and the principal investigator were masked to their allocation status. Those in the treatment arm were allocated to one of two treatment groups of five, each run individually by one of the music therapists. Each group had sixteen ninety minute weekly sessions with followup at eight weeks. Treatment and control groups received standard care. The primary measure was the Person’s Relating to Others Questionnaire (Birtchnell and Evans 2004) Secondary measures were the Basic Empathy Scale (Jolliffe and Farrington 2006a), The Multi-Scale Dissociation Inventory (Briere, 2002) and an observational measure, the Chart of Interpersonal Reactions in Closed Living Environments (Blackburn and Glasgow, 1993). Quantitative data from these measures were examined for associations with qualitative data from semi-structured interviews administered to the music therapists and analyzed using Interpretative Phenomenological Analysis (Smith et.al. 2009) Findings from the results of the primary measure demonstrated statistically significant (Mann Whitney U: p<.05) reductions in favour of the treatment group compared to the control, in intrusive, restrictive and possessive behaviors and helpless or self-denigrating behaviours. There were improvements over time within the treatment group in the domains of sociability and hostility (Friedman Test :p<.04). The use of a manual was shown to help the music therapists manage the risk of violence without constraining their creativity. Two years after the end of the treatment 78% of treatment participants had moved to conditions of lower security over a mean period of 19 months compared with 66% of control subjects over a mean period of 25.5 months. The thesis concludes by situating G-CAMT amongst contemporary music therapy models.

Thesis, University of Bristol, 2013. http://ethos.bl.uk/OrderDetails.do?uin=uk.bl.ethos.684366.
Full textAbstract:
Depression is a common and disabling condition which is often treated with antidepressant medication within the primary care setting. There is growing interest in the possibility that non-pharmacological treatments such as physical activity could lead to a reduction in depressive symptoms. A pragmatic, multi-centre, two-arm, parallel, individually-randomised controlled trial investigated the effectiveness of a facilitated physical activity intervention as an adjunctive treatment to usual care for adults presenting to general practitioners with depression. The intervention comprised three face-to-face sessions and ten telephone calls with a Physical Activity Facilitator over an 8-month period. The primary outcome was depressive symptoms assessed using the Beck Depression Inventory at 4-month follow-up. Secondary . outcomes included quality of life, prescription and use of antidepressants and physical activity at 4-, 8- and 12-months post-randomisation as well as longer term depressive symptoms measured at the 8- and 12-month end-points. 361 patients with a depression diagnosis were recruited from 65 general practices in Bristol and Exeter. Adherence to the intervention was good, with 71 % of those offered the additional treatment receiving an 'adequate dose'. The primary comparative analysis indicated an adjusted between-groups difference in means of -0.54 points (95% CI -3.06 to 1.99; p=0.68) on the Beck Depression Inventory at 4-month follow-up. There was no evidence that the intervention influenced the prescription or use of antidepressants or made any impact on quality of life at any stage. However, there was a significant increase in the amount of physical activity reported by the intervention group (OR = 2.27, 95% CI 1.32 to 3.89; p=0.0003) over the course of the 12-month trial compared to the usual care group. It was clear that adding a facilitated physical activity intervention to usual care did not benefit depression outcomes and that, consequently, it should not be recommended as a treatment option within UK primary care.

Full textAbstract:
O betão autocompactável surgiu a partir da evolução do betão convencional, tendo vindo a mostrar-se ao longo dos anos, um material versátil e eficaz. A menor relação água-ligante e a menor dosagem de agregado são as principais diferenças encontradas no betão autocompactável (além da utilização de adjuvantes e/ou adições). Estas características irão originar uma menor durabilidade das estruturas, consequente do aparecimento da fissuração, devido às grandes tensões geradas nos elementos estruturais, originadas através da retração.
A retração apresenta uma elevada importância na durabilidade das estruturas de betão, nomeadamente, na conceção, dimensionamento, processo construtivo e no comportamento em serviço. Porém, devido aos mecanismos a ela envolvidos estarem ainda longe de serem totalmente compreendidos, têm surgido diversos métodos para a redução deste fenómeno.
De forma a compreender melhor o fenómeno da retração e melhorar as características do betão autocompactável, foi realizado um trabalho experimental para avaliação deste fenómeno, introduzindo dois adjuvantes, um expansivo e um retardador de presa, em duas composições de betão autocompactável com diferentes superplastificantes.
O estudo efetuado provou que o expansivo atua numa idade precoce, contribuindo para uma redução significativa da fissuração nas primeiras idades. No entanto, a utilização simultânea de um expansivo com um retardador de presa, não se mostrou tão eficaz no controle da retração; ### ABSTRACT: The self-compacting concrete has emerged from the evolution of conventionel concrete, proving to be a versatile and effective material over the years. The main differences found in self-compacting (besides the use of adjuvants and/or additives) are lower water-binder ratio and lower aggregate dosage. These features will result in reduced durability of structures, resulting in the appearence of cracks due to large stresses generated in the structural elements, caused by shrinkage. The retraction is of extreme importance in the durability of concrete structures, particularly in the design, sizing, constructive and performance process. Although its perfomance mechanisms are far from being fully understood, several methods have appeared to reduce this phenomenon. In order to further understand the shrinking phenomenon and improve the characteristics of self-compacting concrete, experimental work was conducted by introducing two adjuvants, an expansive and setting retarder in two blends of self-compacting concrete with different superplasticizeres. The study proved that the expansive additive contributed to a significant reduction of cracking at early years. However, the simultaneous use of an expansive with a setting retarder additive, was not as effective in controlling shrinkage.

Esta tese analisa as mudanças na morfologia das interações sociais na Penitenciária Feminina Madre Pelletier (RS), destacando os aspectos relativos aos controles formais e informais produzidos em meio aos jogos de poder pelos diferentes grupos que habitam a prisão. O estudo contempla o período entre 1990 e 2008 e desconstrói a percepção do encarceramento feminino centrado na singularidade, homogeneização e sujeição feminina frente a um único poder: o do Estado, deixando de considerar o poder disseminado entre indivíduos em suas diferentes posições na configuração prisional. Focamos a relação das mulheres com os delitos de drogas, na medida em que este delito tem redefinido a trajetória criminal feminina. Ao mesmo tempo, essa relação adentra a penitenciária e põe em circulação interesses e uma lógica mercantil sustentada pela violência entre grupos. As interações na sociedade prisional feminina passaram a se caracterizar pela instabilidade, pela presença de um código informal sustentado pelas presas, por ambivalências nos discursos e nas práticas relativas à mulher envolvida em delitos de drogas e, por extensão, à mulher. Rebeldia, micro poderes, sexualidade e ações coletivas definem as relações sociais entre as mulheres aprisionadas, longe dos antigos projetos da reabilitação da sociedade moderna.This thesis analyses the morphological changes of the social institutions in the Women’s Prison of Madre Pelletier (RS), bringing out the aspects related to the formal and informal controls produced amid games of power by the different groups that dwell the prison. The study contemplates the period between 1990 and 2008, and deconstructs the perception of the women’s imprisonment centered on the singularity, homogenization and the women’s subjection against a single power: the State’s, not considering the power scattered among the individuals in their different positions in the prison setting. We focused on the women’s relation with the drug offenses, as they have redefined the women’s criminal trajectory. At the same time, this relation enters the prison and causes the circulation of interest, as well as, merchant logic sustained by the violence between groups. The interactions in the women’s prison society began to be characterized by the instability, by the presence of an informal code sustained by the imprisoned, by ambivalences towards the speeches and the practices related to the woman involved in drug offenses and, by extension, to the woman. Rebelliousness, micro powers, sexuality and collective actions define the social relations between imprisoned women, far from the old projects of the rehabilitation of the modern society.

Thesis, Tufts University School of Dental Medicine, 2018. http://pqdtopen.proquest.com/#viewpdf?dispub=10839656.
Full textAbstract:
Aim & Hypothesis: The aim of the study was to compare the time dental students need to answer questions about drug-drug interactions (DDI) when using the Evidence-Based Clinical Decision Support Resource (EBCDSR) UpToDate® to retrieve patient-critical information versus general internet access, during a preclinical session. We hypothesized that the dental students utilizing the UpToDate® would take less time to identify the correct DDIs and obtain higher examination scores, compared with the group with only internet access.
Materials & Methods: The proposed study design was a randomized blinded crossover controlled pilot and each subject examined four computer-based virtual cases, during two study visits. In the first visit, one group assessed two cases presented in axiUm (Tufts University School of Dental Medicine’s electronic health record system), using UpToDate ® access and the other group, using their own electronic resources assessed other two cases with no UpToDate® access, and determined the DDI. At the second visit, after the ten days wash-out period, the cross-over took place. Each case was followed by three questions regarding the drug-drug interactions, focusing on the use of antibiotics, analgesics and local anesthetics. The mean time duration of the sessions conducted by each subject was captured and calculated. Chi-square tests were used for the statistical analysis of the examination scores. All statistical analyses were performed using SAS Version 9.2 (SAS Institute, Cary, NC).
Results: A total of 50 dental students presented for the first study visit and 44 dental students for the second study visit. The third year dental students utilizing the UpToDate® took a similar amount of time to identify the correct DDIs compared with the third year dental students with no UpToDate® access and only internet access (p-value = 0.429). Both groups obtained similar examination scores for all the questions related to antibiotics (p-value = 0.797), analgesics (p-value = 0.850) and local anesthetics (p-value = 0.850).
Conclusions: The current study has shown that UpToDate ® can provide answers to clinical questions at the point of care in a timely manner, with a high level of student satisfaction. Future studies might involve a more seamless entry into EBCDSR’s using “Infobutton” in the Electronic Health Record (EHR).

Thesis, Saybrook University, 2017. http://pqdtopen.proquest.com/#viewpdf?dispub=10251703.
Full textAbstract:
Back problems continue to be a leading cause for disability in all of medicine and are the number one symptom disorder for consulting integrative medicine practitioners. Feldenkrais® practitioners aim to clarify new functional interrelationships towards an improved neuroplasticity-based change in the cognitive construct of one’s own background body schema. These phenomena have been found to clinically correlate to chronic pain through concurrent distortions in the reorganization of usual sensory-motor cortical representations in the brain – being further associated with altered body perception (Wand, et al. 2016). The Feldenkrais Method ® (FM) is a comprehensive approach being manifested through manual sensory contact (FI®) techniques and movement experiences (ATM®) and has been anecdotally purported to improve symptoms and functions in Chronic Non-specific Low Back Pain (CNSLBP). However, there is little scientific evidence to support superior treatment efficacy.
A Randomized Controlled Trial compared a novel Virtual Reality Bones™ / Feldenkrais® Movement (VRB3/FM) intervention against more conventional protocols for Core Stabilization Biofeedback / Motor Control Exercises (CSB/MCE). The (VRB 3)™ treatment component consisted of full-scale skeletal models, kinematic avatars, skeletal density imagery, temporal bone-vestibular system relationships, and haptic self-touch techniques being aimed to re-conceptualize participant’s prior notions and beliefs regarding body schema and low back pain (LBP). N=30 participating patients with CNSLBP were assigned to either the experimental group (VRB3/FM @ N=15) or the control group (CSB/MCE @ N=15). Known confounding biopsychosocial variables were controlled via stratified-random assignment on the FABQ. Treatment Outcome measures included VAS-PAIN, RMDQ, PSFS, and Timed Position Endurances Tests – including Flexion / Extension Ratios at baseline, 2-weeks, 4-weeks and 8-weeks. Statistical Analysis was conducted using Wilcoxon Rank Sum and paired, two-tailed t-test. Results showed that the VRB3/FM group demonstrated greater improvement in all treatment outcome measures as compared to the matched CSB/MCE control group.
This is the first RCT study to demonstrate that a Feldenkrais Method® based approach being combined with Virtual Reality Bones™ can be more efficacious for the treatment of CNSLBP than the current and accepted physical medicine standard of isolated Core Stabilization Biofeedback / Training and Motor Control Exercises. Future multi-site RCT studies with larger sample sizes are therefore recommended.

Full textAbstract:
Background: Evidence from armed conflict settings points to high levels of intimate partner violence (IPV) against women. Current knowledge on how to prevent IPV is limited – especially within war-affected settings. This research aims to inform the prevention of IPV in conflict-affected settings, specifically identifying community exposures to violence and traumatic events and their consequences among men and women and the impact of an IPV prevention intervention in Côte d’Ivoire. Methods: This thesis represents a coordinated programme of research comprised of four studies: (1) a systematic review of violence against women (VAW) prevention interventions in conflict settings; (2) a community survey to determine community levels of exposure and perpetration of IPV, non-partner violence and traumatic events before, during and after a period of conflict; (3) a cluster randomised controlled trial to determine the added value of an IPV prevention intervention working with men; and (4) a nested cohort study to assess the gendered and temporal impact of violence and the intervention on mental health. Results: The systematic review uncovered an extensive VAW prevention programme but limited research on its effectiveness. The community survey found high levels of IPV, non-partner violence and traumatic events among women and men. Women experienced higher overall levels of violence compared with men. The cluster RCT found significant differences between men in the intervention and control groups with regard to their ability to manage conflict and their increased engagement in gender-equitable behaviours. Among women, the cohort study found that factors significantly associated with post-traumatic stress disorder (PTSD) included male partner alcohol use and experience of IPV in the past year. Men were strongly protected from PTSD if they cohabitated with their female partner. A research commentary further advocates for violence prevention programming in conflict settings with attention to all forms of violence against women, including IPV. Conclusion: In conflict-affected settings, policy approaches and interventions that aim to improve the lives of survivors should work towards programming that promotes gender equality and protects women and girls from abuse.

Resumo: Esta pesquisa busca compreender a entrada dos assistentes sociais no sistema educacional e suas implicações, considerando hoje um trabalho em expansão em alguns Estados brasileiros, como São Paulo, Rio de Janeiro e Minas Gerais. Teve por objetivo analisar o surgimento do Serviço Social Escolar de Limeira, um setor premiado com o Selo Prata pelo Programa da Qualidade Total na Educação. Utilizando análise documental e entrevistas, observamos que o Serviço Social Escolar incorporou práticas da Gestão da Qualidade Total na Educação, delineada pelo grupo que se nomeará por Comitê Executivo. Assim, meu primeiro problema foi entender a entrada no espaço educacional de Limeira de uma linguagem empresarial encabeçada pela ideia de qualidade total, nos serviços prestados. Essa investigação evidenciou a existência de relações de forças locais que alimentam e validam esse espaço de trabalho para os assistentes sociais. A partir de tais constatações, mostrou-se relevante compreender, as práticas dos agentes do Serviço Social Escolar, evidenciadas pela análise de prontuários e fichas de alunos do arquivo do assistente social de uma escola de educação infantil e ensino fundamental. A análise oferece uma aproximação de novas formas de controle e enquadramento pela via da escola. Permite-nos perceber que a criação deste espaço de trabalho não é uma conquista desta categoria, mas sim o resultado de um jogo de interesses que leva a inserção de assistentes sociais nos espaços escolares.
Abstract: This research seeks to understand the entrance of social assistants in the educational system and its implications, considering today a work in expansion in some Brazilian states such as Sao Paulo, Rio de Janeiro and Minas Gerais. It had as objective to analyze the appearing of Scholar Social Service of Limeira, a sector prized with the Silver Stamp for the Total Quality Program in Education, formed by the group that will be named as Executive Committee. So, my first problem was to understand this entrance in the educational space in Limeira of an enterprise language headed by the total quality idea, in the services done. This investigation evidenced the existence of local forces relations that feed and valid this work space for the social assistants. From such facts, it was shown relevant to understand, the practices of the Scholar Social Service agents, evidenced by assessments analyses and students' profiles of the social assistant file of a pre and primary school. The analyses offer an approach of a new way of controlling and fitting by the school. It allows us to notice that the creation of this work space is not a conquest of this category but the result of a game of interests that leads to the insertion of social assistants in the scholar spaces.

A questão do trabalho e do trabalhador nas organizações tem ocupado importância crescente no debate atual. A retomada da centralidade da categoria trabalho, para a compreensão do ser humano, da construção de sua identidade e do estabelecimento das relações sociais, demonstra a busca do sentido do trabalho para o sentido da vida em sociedade. As formas de produção e reprodução das bases materiais capitalistas levaram o trabalho a ser sinônimo de sofrimento e subsistência. Na contramão deste processo, as políticas de valorização do trabalho, e em específico a este estudo, na área de política pública de saúde, buscam a superação das relações precárias, da alienação e da transformação do trabalhador em um mero insumo. Na trajetória da política pública de saúde no Brasil, é possível identificar a importância da participação social, enquanto espaços legítimos e institucionalizados da democracia brasileira, através dos espaços de Controle Social – Conselhos e Conferências de Saúde, para a construção e consolidação do que hoje é o Sistema Único de Saúde. Para a qualificação constante desta política no atendimento às demandas da população, o trabalhador retoma o papel de produtor e agente de seu trabalho, como insubstituível na produção do cuidado em saúde. Dificuldades históricas no reconhecimento do trabalhador e nas condições de trabalho em saúde são apresentadas recorrentemente nos documentos das Conferências, demonstrando que o Controle Social já identificava a importância e reivindicava modificações no status quo. A presente pesquisa demonstra, a partir da análise documental, a relação estabelecida entre o Controle Social e a formulação da agenda governamental para a valorização do trabalhador da saúde, trazendo contribuições para reflexões e debates, identificando avanços e acúmulos, bem como desafios.The issue of worker and work in organizations has occupied increasingly important in the current debate. The recovery of the centrality of category work, to understand the human being, the construction of identity and the establishment of social relationships demonstrates the search for the meaning of work for the meaning of life in society. The forms of production and reproduction of material bases capitalists led the work to be synonymous with suffering and survival. Against this process, policies valorization of work, and in particular to this study, in the area of public health policy, seeking to overcome the precarious relations, alienation and transformation of the worker into a mere scrap. In the course of public health policy in Brazil, it is possible to identify the importance of social participation, while legitimate and institutionalized spaces of Brazilian democracy, through the spaces of Social Control - Health Councils and Conferences for the construction and consolidation of what is now the Sistema Único de Saúde (Unified Health System) for the qualification contained in this policy in meeting the demands of the population, the worker resumes the role of producer and agent for his work as irreplaceable in the production of health care. Historical difficulties in recognizing and working conditions of health workers are repeatedly presented in the documents of the Conference, showing that the Social Control has identified the importance and demanded changes in the status quo. This research demonstrates, from the documentary analysis, the relationship between Social Control and the formulation of the government agenda for the valuation of health worker, bringing contributions to discussions and debates, identifying advances and accruals as well as challenges.

Full textAbstract:
This dissertation is a participant observer’s account of implementing a multisite, randomised controlled trial within Her Majesty’s Prison Service. It adds to a scarce literature detailing the steps involved in implementing experiments in custodial settings by providing a candid account of the route from planning to successful implementation. The randomised controlled trial was designed to evaluate the effectiveness of the Sycamore Tree Programme. This programme’s goal is to teach prisoners the wider harm of crime and includes a face-to-face meeting between a victim of crime and the participating offenders. It derives its rehabilitative potential from restorative justice and seeks to foster hope that change is possible for offenders, thus aiding them to desist from crime. Its development and theoretical basis are described for the first time. In an in-depth narrative the dissertation details how at every stage strategies were developed to manage participant procurement, random assignment, maintaining treatment integrity, and preparing for final outcome measurements. The randomised controlled trial was designed to produce an individual experiment in eight prisons. These will be combined in a meta-analysis as well as analysed as a pooled sample. Overall the implementation process took close to two years and involved a charitable body, Her Majesty’s Prison Service, the National Offender Management Service, and two police forces. This work has demonstrated how the unstable nature of English prison populations and the risk-averse climate must be addressed when conducting experiments in that environment. It has also illustrated the gap between the rhetoric of evidence-based policy and the facilitation of research designed to seek that evidence. Nevertheless, developing trusting relationships and combining rapidly learnt skills with inherent abilities ensured that the evaluation methodology was supported and protected through the various challenges it met. Finally, the dissertation suggests conditions for closer collaboration between government executive bodies and researchers that might increase the number of experiments undertaken in prisons. It also aims to encourage researchers that prison experiments, although not easy, are feasible, defendable, and, above all, worthwhile.

In general case, the frequency of the PWM is adjusted by changing the resistor or capacitor. However, it’s time-consuming and inconvenient to replace the resistor or the capacitor while changing the frequency. Hence, this research is aimed to propose two solutions of this problem. 1. Auto-setting frequency: by designing a detector which will automatically detect the loading and provide a suitable frequency; 2. Manual setting: by conducting the four bits to control the frequency of the PWM for the purpose of time-efficiency and convenience which increases no extra cost while changing the frequency and can be easily manipulated as well. The main purpose of changing the frequency is to stabilize the variant of the ripple voltage in the same capacitance of different loadings. Therefore, the output of the ripple voltage can be decreased by changing the frequency according to the loadings.

This thesis presents a novel speech application on the Mobile Devices. Traditional speech interfaces such as Apple Siri and Google Voice Search cannot directly handle system settings in an off-line status of the mobile devices, subject to the condition of the network environment. Therefore, this paper presents a good voice control app for offline status of the voice control APP. The proposed method simplifies the user''s habits and some commonly used interface application modes such as touch operation on the screen, and then involves voice control operation for system setting while Wi-Fi setting is developed as an example with basic offline voice control. We also implement Wi-Fi authentication by using voice in this thesis.

PID控制器目前在程序工業中仍然被廣泛地使用，主要是因為PID只有三個 調諧參數；早期有關PID調諧法則有很多，但大多只適合Ｓ領域，因此， 本研究以PID控制器調諧為基礎，在Ｚ領域之下對一階帶有時延之程序作 調諧。首先對系統作正規化(Normalize)分析，以數值搜尋法搜尋出最適 調諧參數群，進而應用最小平方迴歸法迴歸出一套PID控制器調諧參數之 調諧公式。本研究分別使用連續式PID控制器及數位式PID控制器作為調諧 控制器；在數位式PID控制中，重要參數之一的取樣週期；本研究也應用 迴歸分析迴歸出最適取樣週期與程序參數間之關係式。由於一般Ｚ轉換對 於程序延遲時間與程序時間常數之間非整數倍關係時，無法作正確的轉換 ，因此，研究中採用修正型Ｚ轉換，以克服延遲時間與取樣時間非整數倍 關係之問題。在連續系統中，本研究直接對串級控制系統作調諧。在串級 控制系統中，若使用傳統調三個參數之PID控制器為調諧控制器，則必須 同時調六個參數；本研究以OPT作為調諧控制器，只須同時調兩個參數， 調諧過程比較節省數值搜尋所須之時間。同樣的，本研究也應用最小平方 迴歸法迴歸出一套有關連續式PID控制器之串級控制調諧公式。本研究所 列之調諧公式適合作PID控制之用，尤其在單環路控制系統中，一并提供 取樣週期之計算公式；免除了傳統憑經驗選定取樣週期之困擾。

In this thesis, the empirical parameter setting methodology is applied to the press controller. During every operation cycle of the press, in order to obtain the maximum press power, the head of the press must be located on the top position precisely. To record these empirical parameters of braking delay time then transmit them into the register of the PLC. The proposed empirical parameter setting methodology can fulfill these requests. In this thesis, two kinds of control strategy are adopted. The first kind can be used to the variable speed DC motor and DISCO motor, which do not have pulse. The second kind can be used to the variable speed Eddy Current Coupling motor and inverter control motor, which do have pulse. The PLC (Programmable Logic Controller) is cooperating with inverter to control the speed of the motor. These empirical parameters ensure the maximum press power and improve the operation safety.

Gear is one of the widely-used transmission components. With the development of the technology, we value gear precision than before; therefore, the manufacturing method is very important. In manufacturing, hobbing machine, gear-shaping machine, and other machines are widely-used in the manufacture of various gears. Among them, hobbing machine is easy to set, efficient in production, and the quality of products is stable. After regrinding, the precision and quality of products are great, so the hobbing machine is widely-used. However, compare with other machines, hobbing machine is easy to shake when process due to the snatchy cutting in hobbing process. Therefore, in order to promote better stability when processing, the research focuses on the following: After the hobbing machine is assembled, in the preference setting process of FANUC controller and verification process of controller adjustment, we use Servo-Guide software to intercept Pass Error Messages from Motorserver Encoder to judge the speed gain of each axle and broadband adjustment. By doing this, we can control the effect of High Frequency Resonance.

The purpose of this paper is to propose an automatic electrical parameters identification method and setting of current controller gain for servo motor drives. Current controllers are required in prior for electrical parameters identification as comparing to previous method as shown in reference for example. Since the electrical parameters are required for current controller gain setting. In previous approach, the inaccurate current controller gains setting during electrical parameters identification may result in inaccurate parameter identification results. In contrast, the proposed electrical parameter identification improves the accuracy concern for not using current controller during identification process. Moreover, the current controller gains are set automatically once the electrical parameters are derived using the proposed method. Experimental results are derived using an RZ/T1-based platform. As confirmed the tested bandwidth of current loop is different from its designed value when the electrical parameters error exists. In contrast, the measured results show the bandwidth of current control for test agrees with that of its design using the proposed method using the proposed method and thereby confirming the effectiveness of the proposed automatic electrical parameters identification method and setting of current controller gain for servo motor drives.

The objective of this essay is to apply the fuzzy control concepts on the setting of PID controller parameters. By this approach, the performance of auger grinding machine is improved, and the auger knife slot gets smoother surface. Auger grinding machines are the company’s main equipments. Firstly, the mathematical model of the grinding machine and its servo control system are developed by characteristic data. Secondly, the system operation conditions are simulated by using ‘Simulink’ of Matlab package with the PID parameter set which is created by experienced engineers. Then, the fuzzy control method is applied to establish the membership function, rule base and fuzzy inference system (FIS) in order to get a better tuning of the PID parameters. Simulation results show that some performance indexes such as rise time, percentage overshoot, steady state error, etc. are improved. Lastly, the simulation results are applied to the original equipments with the proposed control parameter settings. Quality inspection has found that the scales phenomenon of drill bit has been much improved. Keywords: PID parameters, Servo control system, Fuzzy control rule base, Membership function

Full textAbstract:
Falls are a relatively frequent occurrence amongst older people. Rates of falls amongst patients in subacute care are substantially higher than amongst people living in the community. Falls have been reported to cause physical and psychological injury, increase the likelihood of being discharged to nursing home, and are associated with longer lengths of stay in hospital. Thus, minimisation of falls in the subacute hospital setting is of high public health importance. (For complete abstract open document)

"A Fast Settling Oversampled Digital Sliding-Mode Controller for DC-DC Buck Converters." Doctoral diss., 2013. http://hdl.handle.net/2286/R.I.20800.
Full textAbstract:
abstract: Sliding-Mode Control (SMC) has several benefits over traditional Proportional-Integral-Differential (PID) control in terms of fast transient response, robustness to parameter and component variations, and low sensitivity to loop disturbances. An All-Digital Sliding-Mode (ADSM) controlled DC-DC converter, utilizing single-bit oversampled frequency domain digitizers is proposed. In the proposed approach, feedback and reference digitizing Analog-to-Digital Converters (ADC) are based on a single-bit, first order Sigma-Delta frequency to digital converter, running at 32MHz over-sampling rate. The ADSM regulator achieves 1% settling time in less than 5uSec for a load variation of 600mA. The sliding-mode controller utilizes a high-bandwidth hysteretic differentiator and an integrator to perform the sliding control law in digital domain. The proposed approach overcomes the steady state error (or DC offset), and limits the switching frequency range, which are the two common problems associated with sliding-mode controllers. The IC is designed and fabricated on a 0.35um CMOS process occupying an active area of 2.72mm-squared. Measured peak efficiency is 83%.Dissertation/Thesis
