Police Organizational Performance In The State Of Florida:confirmatory Analysis Of The Relationship Of The Environment And Design Structure to Performance

Goltz, Jeffrey 01 January 2006 (has links)
To date, police organizations have not been rigorously analyzed by organizational scholars and most analysis of these organizations has been captured through a single construct. The purpose of this study is to develop confirmatory police organizational analysis by validating a multi-dimensional conceptual framework that explains the relationships among three constructs: environmental constraints, the design structures of police organizations, and organizational performance indicators. The modeling is deeply rooted in contingency theory, and the influence of isomorphism and institutional theory on the covariance structure model are investigated. One hundred and thirteen local police organizations from the State of Florida are included in this non-experimental, cross-sectional study to determine the direct effect of the environmental constraints on the performance of police organizations, the indirect effect of environmental constraints on the performance of police organizations via the organizational design structure of police organizations, and the direct affect of organizational design structure on performance of police organizations. For the first time, structural equation modeling and data envelopment analysis are used together to confirm the effects of the environment on police organization structure and performance. The results indicate that environmental social economic disparity indicators have a large positive effect on police resources and a medium effect on police efficiency. Propensity of crime indicators has a large negative effect on police resources, and population density has a small to medium negative effect on crime clearance. Structure has a much smaller effect on performance than the environment. The results of the efficiency analysis revealed unexpected findings. Three of the top five largest police organizations in the study scored maximum efficiency. The cause of this unexpected result is explained and confirmed in the covariance model. The study methodology and results enhances the understanding of the relationship among the constructs while subjecting environmental and police organizational data to two comprehensive analytical techniques. The policy implications and practical contributions of the study provide new knowledge and information to organizational management of police organizations. Furthermore, the study establishes a new approach to police organizational analysis and police services management research called Police Services Management Research (PSMR) that encompasses a variety of disciplines with a primary responsibility of theory building and the selection of theoretical framework.

The Dilemmas of Bringing Your Culture With You: The Career Advancement Challenges of African-American Women Foundation Executives

Logan, Angela R. January 2014 (has links)
Indiana University-Purdue University Indianapolis (IUPUI) / Grounded in leadership, cultural, communication, and gender studies, this dissertation investigates the challenges African-American women executives in the philanthropic foundation sector faced as they strive to have their culture legitimated within the culture of the workplace. Through the use of case study methodology, I examined the experiences of participants by conducting oral history interviews that traced their critical path to leadership. I also incorporated my own experiences in the field to further explore the connections between race, gender, and leadership styles in philanthropic organizations. The interviews and my own auto-ethnographic research explored the possible consequences of black executive women in the foundation world not being able to share aspects of their cultural lives in workplace networks and the impact of the critical exclusion of who they really are as whole human beings on the quality of their careers. An analysis of data collected from the interviews revealed key factors critical to the success of study participants. First was the presence of familial or close adults actively engaged in philanthropic activity during the participants’ formative years. Second was a strong influence of a faith tradition. Additionally, the date revealed that participants’ involvement in outside leadership roles, often tied to their racial and gender identities, were not capitalized on by employers. This study achieved several key outcomes. First, it afforded participants an opportunity to develop the personal satisfaction of expanding the body of knowledge related to leadership development within the philanthropic foundation sector. Additionally, by sharing their stories, these individuals were able to develop or strengthen mentorship relationships. Lastly, this study has the potential of being of significant benefit to the greater philanthropic foundation sector, since it worked towards the expansion of the body of knowledge specific to the issues of gender and cultural differences within the foundation sector.

Die bepaling van standaarde vir die eenheidsbestuurder in geselekteerde hospitale

Van Dyk, Anneline Lynette 12 1900 (has links)
Thesis (MCur)--Stellenbosch University, 2000. / ENGLISH ABSTRACT: The traditional management practice of the unit manager has changed dramatically in the past decade. She is responsible to supply nursing services in an environment which is characterized by smaller operational budgets, rapid developments and changes in every sphere. The researcher has identified deficiencies in the management process of the unit manager. This led to the evaluation of the management activities of the unit manager in a selected group of hospitals. A quantitative, non-experimental, descriptive approach was followed with a questionnaire survey as research design. Standards were set and the management activities were evaluated against these standards. The main findings were: • The unit manager was not 100% involved in her comprehensive management task • The unit manager did not have the necessary training to empower her to manage effectively. The researcher recommends that the unit manager should be empowered by inservice education programmes but should also follow the formal management programmes at a recognized tertiary education institution. Keywords: Unit management / Standard formulation / AFRIKAANSE OPSOMMING: Die tradisionele bestuurspraktyk van die eenheidsbestuurder het oor die afgelope dekade dramaties verander. Sy is verantwoordelik vir die verskaffing van verpleegdienste in 'n omgewing wat gekenmerk word deur kleiner operasionele begrotings, vinnige vooruitgang en veranderinge op alle gebiede, Die navorser het leemtes in die bestuursproses van die eenheidsbestuurder geïdentifiseer. Dit het gelei tot die evaluering van die bestuursaktiwiteite van die eenheidsbestuurder in 'n geselekteerde groep hospitale. 'n Kwantitatiewe, nie-eksperimentele beskrywende navorsingsbenadering is gebruik met 'n vraelysopname as navorsingsontwerp. Standaarde is gestel waarteen die bestuursaktiwiteite geëvalueer is. Die belangrikste bevindinge was dat: • Die eenheidsbestuurder nie 100% betrokke was by haar omvangryke bestuurstaak nie • Die eenheidsbestuurder nie oor die nodige opleiding beskik wat haar bemagtig om hierdie bestuurstaak effektief te verrig nie. Die navorser beveel aan dat die eenheidsbestuurder bemagtig moet word deur middel van indiensopleidingsprogramme maar ook deur formele bestuursopleiding aan 'n erkende tersiêre opvoedkundige intansie moet te volg.

A presente pesquisa caracteriza-se como um estudo de caso de caráter exploratório e teve como objetivo mapear a influência do estágio pós-doutoral sobre a produção dos docentes em programas de pós-graduação da Universidade de São Paulo. O estágio pós-doutoral é um item extra na carreira acadêmica que atua como processo de atualização e incremento de conhecimento, por meio de socialização e contato com mainstream da ciência de uma determinada área. O presente estudo trabalhou basicamente utilizando como fonte de dados o sistema Lattes, onde a construção de um índice permitiu uma pesquisa exaustiva e objetiva trabalhando em duas vertentes, uma se pautou no levantamento da produção docente antes e depois da realização do pós-doutorado e outra se pautou na comparação do desempenho acadêmico coletivo entre os pesquisadores que optaram por realizar estágio pós-doutoral e os que optaram por não realizar estágio pós-doutoral. A pesquisa encontra-se circunscrita nas grandes áreas de Biológicas, Engenharias, Exatas e da Terra e Saúde. Com metodologia bifurcada, no panorama ex-ante e ex-post a pesquisa trabalhou com a população de 86 docentes e na comparação entre doutores com e sem realização de estágio pós-doutoral, com uma amostra de 198 docentes. Os resultados da pesquisa apontam que o pós-doutorado possui uma leve influência sobre o aumento de publicações em revistas internacionais Qualis A, possui influência mais visível sobre a produção quando realizado no Exterior e possui impactos positivos diante de um maior intervalo entre a conclusão do doutorado e a realização do pós-doutorado, entre os docentes com e sem pós-doutorado existe uma tendência de acréscimo de produção para os pesquisadores com pós-doutorado, mas essa tendência não é tão forte e incisiva, mesmo após um maior tempo de conclusão do doutorado, diversos casos de pesquisadores com produção e desempenhos similares são vistos, independentemente da realização ou não de pós-doutorado. / This research is an exploratory case study and has as it as objective to map the influence of the post-doctorate stage about production of the professors in graduate studies of the University of São Paulo.

The estimation of Eucalyptus plantation forest structural attributes using medium and high spatial resolution satellite imagery.

January 2008 (has links)
Sustaining the socioeconomic and ecological benefits of South African plantation forests is challenging. A more systematic and rapid forest inventory system is required by forest managers. This study investigates the utility of medium (ASTER 15 m) and high (IKONOS 1-4 m) spatial resolution satellite imageries in an effort to improve the remote capture of structural attributes of even-aged Eucalyptus plantations grown in the warm temperate climatic zone of southern KwaZulu-Natal, South Africa. The conversion of image data to surface reflectance is a pre-requisite for the establishment of relationships between satellite remote sensing data and ground collected forest structural data. In this study image-based atmospheric correction methods applied on ASTER and IKONOS imagery were evaluated for the purpose of retrieving surface reflectance of plantation forests. Multiple linear regression and canonical correlation analyses were used to develop models for the prediction of plantation forest structural attributes from ASTER data. Artificial neural networks and multiple linear regression were also used to develop models for the assessment of plantation forests structural attributes from IKONOS data. The plantation forest structural attributes considered in this study included: stems per hectare, diameter at breast height, mean tree height, basal area, and volume. In addition, location based stems per hectare were determined using high spatial resolution panchromatic IKONOS data where variable and fixed window sizes of local maxima were employed. The image-based dark object subtraction (DOS) model was better suited for atmospheric correction of ASTER and IKONOS imagery of the study area. The medium spatial resolution data were not amenable to estimating even-aged Eucalyptus forest structural attributes. It is still encouraging that up to 64 % of variation could be explained by using medium spatial resolution data. The results from high spatial resolution data showed a promising result where the ARMSE% values obtained for stems per hectare, diameter at breast height, tree height, basal area and volume are 7.9, 5.1, 5.8, 8.7 and 8.7, respectively. Results such as these bode well for the application of high spatial resolution imagery to forest structural assessment. The results from the location based estimation of stems per hectare illustrated that a variable window size approach developed in this study is highly accurate. The overall accuracy using a variable window size was 85% (RMSE of 189 trees per hectare). The overall findings presented in this study are encouraging and show that high spatial resolution imagery was successful in predicting even-aged Eucalyptus forest structural attributes in the warm temperate climates of South Africa, with acceptable accuracy. / Thesis (Ph.D.) - University of KwaZulu-Natal, Pietermaritzburg, 2008.

An investigation into using textural analysis and change detection techniques on medium and high spatial resolution imagery for monitoring plantation forestry operations.

Norris-Rogers, Mark. January 2006 (has links)
Plantation forestry involves the management of man-made industrial forests for the purpose of producing raw materials for the pulp and paper, saw milling and other related wood products industries. Management of these forests is based on the cycle of planting, tending and felling of forest stands such that a sustainable operation is maintained. The monitoring and reporting of these forestry operations is critical to the successful management of the forestry industry. The aim of this study was to test whether the forestry operations of clear-felling, re-establishment and weed control could be qualitatively and quantitatively monitored through the application of classification and change detection techniques to multi-temporal medium (15-30 m) and a combination of textural analysis and change detection techniques on high resolution (0.6-2.4 m) satellite imagery. For the medium resolution imagery, four Landsat 7 multi-spectral images covering the period from March 2002 to April 2003 were obtained over the midlands of KwaZulu-Natal, South Africa, and a supervised classification, based on the Maximum Likelihood classifier, as well as two unsupervised classification routines were applied to each of these images. The supervised classification routine used 12 classes identified from ground-truthing data, while the unsupervised classification was done using 10 and 4 classes. NDVI was also calculated and used to estimate vegetation status. Three change detection techniques were applied to the unsupervised classification images, in order to determine where clear-felling, planting and weed control operations had occurred. An Assisted "Classified" Image change detection technique was applied to the Ten-Class Unsupervised Classification images, while an Assisted "Quantified Classified" change detection technique was applied to the Four-Class Unsupervised Classification images. An Image differencing technique was applied to the NDVI images. For the high resolution imagery, a series of QuickBird images of a plantation forestry site were used and a combination of textural analysis and change detection techniques was tested to quantify weed development in replanted forest stands less than 24 months old. This was achieved by doing an unsupervised classification on the multi-spectral bands, and an edge-enhancement on the panchromatic band. Both the resultant datasets were then vectorised, unioned and a matrix derived to determine areas of high weed. It was found that clear-felling operations could be identified with accuracy in excess of 95%. However, using medium resolution imagery, newly planted areas and the weed status of forest stands were not definitively identified as the spatial resolution was too coarse to separate weed growth from tree stands. Planted stands younger than one year tended to be classified in the same class as bare ground or ground covered with dead branches and leaves, even if weeds were present. Stands older than one year tended to be classified together in the same class as weedy stands, even where weeds were not present. The NDVI results indicated that further research into this aspect could provide more useful information regarding the identification of weed status in forest stands. Using the multi-spectral bands of the high resolution imagery it was possible to identify areas of strong vegetation, while crop rows were identifiable on the panchromatic band. By combining these two attributes, areas of high weed growth could be identified. By applying a post-classification change detection technique on the high weed growth classes, it was possible to identify and quantify areas of weed increase or decrease between consecutive images. A theoretical canopy model was also derived to test whether it could identify thresholds from which weed infestations could be determined. The conclusions of this study indicated that medium resolution imagery was successful in accurately identifying clear-felled stands, but the high resolution imagery was required to identify replanted stands, and the weed status of those stands. However, in addition to identifying the status of these stands, it was also possible to quantify the level of weed infestation. Only wattle (Acacia mearnsii) stands were tested in this manner but it was recommended that in addition to applying these procedures to wattle stands, they also are tested in Eucalyptus and Pinus stands. The combination of textural analysis on the panchromatic band and classification of multi-spectral bands was found to be a suitable process to achieve the aims of this study, and as such were recommended as standard procedures that could be applied in an operational plantation forest monitoring environment. / Thesis (Ph.D.)-University of KwaZulu-Natal, Pietermaritzburg, 2006.

Medical Information Systems & the Nursing Profession : a Sociotechnical Approach

Andersson, Johanna, Hallberg, Ellinor January 2018 (has links)
Due to the digitalization era and challenges faced by the healthcare sector, Medical Information Systems are now being extensively used at hospitals. The implementation of the systems is a complex task which entails a need for careful considerations from a managerial view, since the main purpose with implementing the systems is for managerial control. One of the things management should consider is the professional aspect. The nursing profession is a highly specific one, and this could implicate special considerations. The aim of this master’s thesis is to take on a sociotechnical approach towards the implementation of Medical Information Systems and investigate how the nursing profession is affecting the implementation process, and what it may implicate for hospital management. To answer the research question a qualitative approach has been chosen. The empirical data has been gathered through semi-structured interviews with nurses from the case organization. The result implies that the nursing profession have a substantial impact on the implementation process. Instead of embracing the instructions and support offered by management, the nurses develop their own way of working within the system.
