Instrument Design in Selected Works for Solo Multiple Percussion

January 2012 (has links)
abstract: Instrument design is intrinsic to multiple percussion solo performance preparation, from formulating a physical layout of instruments that best suit each work's technical requirements to fabricating unique instruments to fulfill each composer's sonic specifications. Several works in the multiple percussion repertoire require setups comprised partly or entirely of performer-built instruments. Given that performers have varying degrees of expertise with instrument design and construction, the specialized instruments created do not necessarily meet the level of care with which many of the masterworks in the percussion field were created. Even with the many articles, books, and other publications regarding the instrument design issues of specific works, solo percussion literature is so varied that many set-ups are created using a set of nebulous guidelines. Developing solutions to the problems inherent in multiple percussion instrument design is clearly a continuing effort. Instrument and setup design within selected works for solo multiple percussion is the focus of this document and will be addressed through specific examples from literature commonly performed on concert stages and educational institutions. The scope of this document is limited to the widely applicable design issues of three pieces: Maki Ishii's Thirteen Drums: for Percussion Solo, Op. 66 (1985), David Lang's The Anvil The Chorus: for Percussion Solo (1991), and Steve Reich's Music for Pieces of Wood: for claves (1973). The set-up designs for these pieces suggested by the author are largely the focus for which other material in this document is preparatory. / Dissertation/Thesis / D.M.A. Music 2012

The Effect of Follow-Up Phone Calls After Patient Discharge on 30-day Hospital Readmission Rates

Fyfe, Kristen, Lee-Chan, Tiffany, Marrow, Heather, Cooley, Janet, Warholak, Terri January 2014 (has links)
Class of 2014 Abstract / Specific Aims: The objective of this study was to perform follow-up phone calls to patients after discharge to determine if it had a significant effect in lowering 30- day readmission rates. Methods: Men and women aged 18 years and older who provided informed consent participated in this prospective, pre-post study. The intervention consisted of a scripted follow-up phone call to each patient after discharge. At three to seven days post-discharge, a pharmacy student on an advanced pharmacy practice experience rotation at a teaching hospital called each patient discharged from a designated ward (Med/Surg I), which admits patients with a variety of conditions, such as liver cirrhosis, pneumonia, osteomyelitis, those who are uninsured, or those who require placement after discharge. Information was collected regarding prescription filling, understanding of medication(s), concerns regarding medications, and the community pharmacy he/she used to fill the discharge medications. The specified community pharmacy was then called to verify that the patient filled discharge medications at that pharmacy. The results were compared to the readmission rate in the same ward over the same time period one year prior to implementation of the intervention. Chi-square and descriptive analysis was used and the alpha a priori is 0.05. The institutional review board approved this study. Main Results: Of the 315 people contacted, a total of 89 people completed the survey (28% response rate) and 11 of these participants were readmitted at least once. There was no statistically significant difference between the participant readmission rate and the readmission rates of the total unique admission population of Med/Surg I in 2013 (χ2 = 1.206; p = 0.272). Conclusion: Follow-up phone calls did not significantly impact 30-day readmission rates; however, a downward trend was observed in the participant group.

Etude numérique et théorique du profil à l’explosion dans les équations paraboliques non linéaires / Numerical and theorical study of the blow-up profile in nonlinear parabolic equations

Nguyen, Van Tien 11 December 2014 (has links)
On s’intéresse au phénomène d’explosion en temps fini dans les équations aux dérivées partielles paraboliques non linéaires, particulièrement au profil à l’explosion, des points de vue numérique et théorique. Dans la partie théorique, on s’intéresse au phénomène d’explosion en temps fini pour une classe d’équations semi linéaires de la chaleur perturbées fortement avec l’exposant sous-critique de Sobolev. Travaillant dans le cadre des variables auto-similaires, on obtient d’abord l’existence d’une fonctionnelle de Lyapunov, ce qui constitue une étape cruciale pour établir le taux d’explosion de la solution. Dans une seconde étape, on s’intéresse à la structure de la solution au voisinage du temps et du point d’explosion. On classifie tous les comportements asymptotiques possibles pour la solution quand elle s’approche de la singularité. Ensuite, on décrit les profils à l’explosion correspondant à ces comportements asymptotiques. Dans une troisième étape, on construit pour cette équation une solution qui explose en temps fini en un seul point avec un profil d’explosion prescrit. Cette construction s’appuie sur la réduction en dimension finie du problème et sur l’utilisation du théorème de l’indice pour conclure. Dans la partie numérique, on se propose de développer des méthodes afin de donner des réponses numériques à la question du profil à l’explosion pour certaines équations paraboliques, y compris le modèle de Ginzburg-Landau. Nous proposons deux méthodes. La première est l’algorithme de remise à l’échelle (rescaling) proposé par Bergeret Kohn en 1988, appliqué à des équations paraboliques satisfaisant une propriété d’invariance d’échelle. Cette propriété nous permet de faire un zoom de la solution quand elle est proche de la singularité, tout en gardant la même équation. Le principal avantage de cette méthode est sa capacité à donner une très bonne approximation numérique qui nous permet d’atteindre numériquement le profil à l’explosion. Le profil à l’explosion que l’on obtient numériquement est en bon accord avec le profil théorique. De plus, en considérant une équation de la chaleur non linéaire critique avec un terme de gradient non linéaire, avec peu de résultats théoriques, nous énonçons une conjecture sur le profil à l’explosion, grâce à nos simulations numériques. La deuxième méthode numérique s’appuie aussi sur un raffinement de maillage, dans l’esprit de l’algorithme de remise à l’échelle de Berger et Kohn. Cette méthode est applicable à une plus grande classe d’équations dont les solutions explosent en temps fini sans la propriété d’invariance d’échelle. / We are interested in finite-time blow-up phenomena arising in the study of Nonlinear Parabolic Partial Differential Equations, in particular in the blow-up profile, under the theoretical and numerical aspects. In the theoretical direction, we are interested in particular in finite-time blow-up phenomena for some class of strongly perturbed semilinear heat equations with Sobolev subcritical power nonlinearity. Working in the frameworkof similarity variables, we first derive a Lyapunov functional in similarity variables which is a crucial step to derive the blow-up rate of the solution. In a second step, we are interested in the structure of the solution near blow-uptime and point. We classify all possible asymptotic behaviors of the solution when it approaches to the singularity.Then we describe blow-up profiles corresponding to these asymptotic behaviors. In a third step, we construct for this equation a solution which blows up in finite time at only one blow-up point with a prescribed blow-up profile. The construction relies on the reduction of the problem to a finite dimensional one and the use of index theory to conclude. In the numerical direction, we intend to develop methods in order to give numerical answers to the question of the blow-up profile for some parabolic equations including the Ginzburg-Landau model. We propose two methods.The first one is the rescaling algorithm proposed by Berger and Kohn in 1988 applied to parabolic equations which are invariant under a scaling transformation. This scaling property allows us to make a zoom of the solution when it is close to the singularity, still keeping the same equation. The main advantage of this method is its ability to give a very good numerical approximation allowing to attain the numerical blow-up profile. The blow-up profile we obtain numerically is in good accordance with the theoretical one. Moreover, by applying the method to a critical nonlinear heat equation with a nonlinear gradient term, where almost nothing is known, we give a conjecture for its blow-up profile thanks to our numerical simulations. The second one is a new mesh-refinement method inspired by the rescaling algorithm of Berger and Kohn, which is applicable to more general equations, in particular those with no scaling invariance.

Porovnání přesnosti simultánní a sekvenční line-up identifikace u trestného činu s více pachateli / Comparing simultaneous and sequential line-up identification accuracy for a multiple perpetrator crime

Rác, Jaroslav January 2021 (has links)
Eyewitness identification is being researched for many years prior. However, research on eyewitness identifiaction was mostly conducted with crimes that involved only one perpetrator. For this reason, the present thesis focuses on eyewitness identification for a multiple perpetrator crime. The literature review summarises current knowledge regarding each aspect of recognition and tries to bring insight into the problem of recognition for multiple perpetrator crimes. For the empirical part of this thesis, an experiment was conducted, which aimed to compare simultaneous and sequential line-up identification accuracy. The experiment was changed from live to on-line enviroment due to the pandemic situation. The experiment was conducted on 151 young adult participants. Participants viewed a mock crime video recording involving a perpetrator and his accomplice. Participants were then randomly assigned two simultaneous or sequential line-ups and a target-present or target-absent condition. A week after viewing the video recording, each participant tried to identify the perpetrator and the accomplice in the assigned condition. Results indicated no statistically significant difference between simultaneous and sequential line-up identification. Discussion tries to explain possible influence of changing the...

Scaling up social enterprises to tackle environmental problems : A study exploring scale-up challenges, solutions, and opportunities of social enterprises tackling environmental problems

Svoboda, Karel, Naqvi, Ahmed January 2023 (has links)
AbstractBackground: Among the biggest threats to mankind are various environmental problems which have been mainly triggered by human interference with the planet. There have been various ineffective efforts to mitigate these detrimental effects. Therefore, another solution might come in the form of social enterprises tackling the aforesaid environmental problems. However, to increase the impact, they need to scale up. It is therefore of paramount importance to understand their major scale-up challenges as well as proposed solutions to scale up successfully. Along with that, we also scrutinize further scale-up opportunities to uncover the hidden potential of scaling up. Purpose: The purpose of this study is to explore the relationship between social enterprises and their power to tackle environmental problems. We further build on what social enterprises tackling environmental problems must do to mitigate identified scale-up challenges successfully and to be able to seize any scale-up opportunity that comes their way with the main aim of scaling up their positive environmental impact.Method: Ontology – Relativism; Epistemology – Social Constructionism; Strategy –Qualitative, Exploratory; Approach – Inductive; Design – Grounded theory; Data Collection –10 semi-structured interviews; Sampling – Purposive, snowball; Data Analysis – Grounded AnalysisConclusion: Several factors hinder scaling up and solutions to those lie mainly in four key concepts i.e. business idea, value proposition, competency and collaboration. That has been presented in our proposed model (The Hot Air Balloon Model of Scaling Up). We believe that if these four key concepts are well addressed by SEEPs, they are likelier to overcome challenges as well as are in a better position to attract opportunities. Successful scale-up leads to better financial performance along with the overall objective of scaling up the positive environmental impact.

Rozcvičení v atletice a jeho vliv na explozivní sílu / The effect of Warm Up Protocols on Explosive Power Performance in Track and Field

Mašková, Alžběta January 2017 (has links)
Title: The effect of Warm Up Protocols on Explosive Power Performance in Track and Field Objectives: The main aim of this thesis was to compare three types of warm up protocols and their effects on explosive power performance. Methods: This thesis tested 43 students of UK FTVS, who visited Athletic Conditioning lessons. The group consisted of 28 men (height 183,2+-/5,6 cm) and 15 women (166,3 +-/5,7 cm) aged 20-23 years. There was six measuring sessions separated by a week off. They performed a 800 m aerobic warm up mean run, followed by one of three types of warm-up protocols (static, dynamic, balance). Each of the warm-up protocol was performed two times in the opposite order. The experiment examined the explosive power of lower limbs and upper body/limbs. Performance score were recorded from vertical jump, a ball throw, and medicine ball front throw. Results: The thesis did not confirm any of the hypotheses. It was found that the active static stretching had a positive medium effect on medicine ball front throw by Cohen scale effect size compared to the active dynamic and the active balance warm-up protocol. Other tests did not prove any significant changes, positive or negative, of any warm up protocols. Keywords: Dynamic warm-up, Static warm-up, Balance warm- up, Testing, Explosive Power

Socioeconomic position and utilisation of preventive health services among adults in the general population

Zhang, Jianzhen (Jenny) January 2007 (has links)
Background: International research has shown that socioeconomically disadvantaged groups experience significantly higher mortality and morbidity rates than other groups. Both cardiovascular disease (CVD) and diabetes are major contributors to Australia's burden of disease, and individuals from lower socioeconomic groups are more likely to be affected by both, and to have worse prognoses and outcomes. There is substantial research evidence that a range of preventive activities can reduce the morbidity and mortality associated with these conditions. Research in countries with good access to primary health care services has demonstrated that socioeconomically disadvantaged groups tend to have higher levels of medical consultations, but make less use of preventive care and screening services. This fact contributes to their poorer health outcomes, as diagnosis will typically occur later than for more advantaged individuals, thus leading to a poorer prognosis. However, to date, there has been little research on the differential utilisation of preventive health services for CVD and diabetes by different socioeconomic groups in Australia. To understand socioeconomic influences on the use of preventive health services, a comprehensive review of the literature of determinants of health service utilisation was conducted and a number of explanations for this relationship considered. It was proposed that the following factors are likely to be important in this relationship: differences in the perception of the availability of, and accessibility to health care, attitudes and beliefs toward preventive health care, having a regular source of care, perception of interpersonal care from general practitioners, and social support. A number of theoretical models were also reviewed; in particular, the Andersen Behavioural Model of Health Service Research Utilisation. Aims: This doctoral research program has described the relationship between socioeconomic position (SEP) and utilisation of preventive health services in relation to CVD and diabetes. It aims to improve the understanding of the determinants of uptake and utilisation of preventive health services in general practice by different socioeconomic groups in Australia. Methods: The study was conducted in Brisbane Australia, in 2004, using a cross-sectional design and a self-administered mailed survey for data collection. A sample of adults aged 25-64 years was selected randomly from the Brisbane Electoral Roll. A conceptual model incorporating a range of relevant socio-demographic, risk-factor and behavioural variables in the relationship between SEP and GP-based use of preventive health services was used to develop a self-administered questionnaire. The questionnaire was pilot-tested and then reviewed by a panel of international experts. A new self-administered questionnaire, the Health Service Utilisation Questionnaire (HSUQ), was developed. It included 79 items: 12 socio-demographic items; 10 items assessing health status, disease conditions and smoking status; 20 items assessing use of health services; and 37 items assessing the factors that might affect use of health services utilisation. The HSUQ was then mailed to 800 randomly selected survey participants. The survey response rate was 65.6 per cent. After exclusion of those patients with cardiovascular diseases and diabetes, the final sample size was 381, consisting of 155 males and 226 females. Socioeconomic indicators were individual education level and family income. Blood pressure, blood cholesterol and blood glucose check-ups by general practitioners (GPs) were used as the major outcome variables. Nine scales and two dichotomous variables that measure those potential factors were derived following Principal Component Analysis and reliability testing. The data were analysed separately by gender, and adjusted for age and each of the socioeconomic indicators. Statistical description, bivariate analysis and multivariable modelling in SPSS were applied for the data analysis. Results: The survey results were suggestive of socioeconomically disadvantaged people being less likely than more advantaged people to utilise preventive health services for CVD and diabetes. For males, the low socioeconomic groups recorded the least use of preventive health services among the three education and income groups, including blood cholesterol and blood glucose check-ups, while the high socioeconomic group recorded the greatest use of preventive health services. There was no apparent relationship between education level and blood pressure check-up, while individuals from low-income families were less likely to go for a blood pressure check-up. For females, most of the results suggested that the low socioeconomic groups were less likely than the high socioeconomic groups to have blood cholesterol and blood glucose check-ups. However, this was not the case for blood pressure check-ups. The results showed that the low and middle socioeconomic groups were more likely than the high socioeconomic groups to have BP check-ups. However, the low socioeconomic groups were still less likely than the middle socioeconomic groups to have a blood pressure check-up. Overall, there was a similar pattern between education and income and the use of GP-based preventive health services among both males and females. The findings from the examination of the mediating factors between SEP and the GP-based use of preventive health services suggested that socioeconomically disadvantaged adults (both low level of education and low income) are more concerned about transport and travel time to health care, and accessibility to health care in terms of finding a GP who bulk bills, the cost of seeing a GP and having a choice of GP. They are also less likely to have a regular place of care and social support. These potential factors are likely to result in a lesser use of preventive health services than their high-SEP counterparts. In addition, the findings also suggested that respondents with a low level of education have less-positive attitudes towards health care, and that those from low-income families do not have a regular care provider and are less likely to visit their GP for a preventive check-up in relation to CVD and diabetes in Australia. Conclusions: Strategies for reducing socioeconomic health inequalities are partly associated with changing social and economic policies, empowering individuals, strengthening social and family networks, and improving the equity of the health care system. Strategies have been recommended for implementation in general practice that are directed at targeting the needs of disadvantaged groups; for example, providing longer consultation time and actively offering information on preventive care. Implementation of health promotion programs is needed in disadvantaged areas to keep the community informed about the availability of health services and to make health services more accessible. The health care system needs to be geographically accessible through improvements to the transport system. In addition, improving access to a regular source of primary health care is likely to be an important step in encouraging low-SEP individuals to use preventive health services.
