Future cenario planning in Brazilian logistics and transportation sector

Nas últimas décadas o setor de logística passou por grandes transformações pelo mundo. Assim, a eficiência do sistema logístico é importante para o crescimento econômico, a diversificação, redução dos custos operacionais e da pobreza. Segundo o Banco Mundial, o Brasil tornou-se uma das maiores economias do mundo, mas os custos logísticos elevados colocam em risco esse crescimento. Estes custos são em grande parte o resultado de diferenças em infraestrutura de cada região, juntamente com os encargos do setor rodoviário, que corresponde por 60% do total do transporte de carga do país. Entretanto, a logística brasileira está às portas de uma nova revolução, em práticas de negócios e eficiência, e também na qualidade e disponibilidade da infraestrutura de transportes e comunicações, e novos projetos e práticas para superar a situação. O objetivo deste estudo não é analisar o presente e as atuais tendências de logística do Brasil e do setor de transporte, mas sim modelar possíveis cenários futuros para os próximos anos. Em outras palavras, este trabalho mostra diferentes possibilidades de como o setor de logística e transporte poderá ser no futuro. Para isso, este trabalho irá utilizar a metodologia de cenários prospectivos e entrevistas com especialistas relacionados da área.

Evaluation of the city of Houston HIV/STD prevention program in Houston Independent School District (HISD) high schools

This cross-sectional study was undertaken to evaluate the impact in terms of HIV/STD knowledge and sexual behavior that the City of Houston HIV/STD prevention program in HISD high schools has had on students who have participated in it by comparing them with their peers who have not, based on self reports. The study further evaluated the program cost-effectiveness for averting future HIV infections by computing Cost-Utility Ratios based on reported sexual behavior. ^ Mixed results were obtained, indicating a statistically significant difference in knowledge with the intervention group having scored higher (p-value 0.001) but not for any of the behaviors assessed. The knowledge score outcome's overall p-value after adjusting for each stratifying variable (age, grade, gender and ethnicity) was statistically significant. The Odds Ratio of intervention group participants aged 15 years or more scoring 70% or higher was 1.86 times; that of intervention group female participants was 2.29 times; and that of intervention group Black/African American participants was 2.47 times relative to their comparison group counterparts. The knowledge score results remained statistically significant in the logistic regression model, which controlled for age, grade level, gender and ethnicity. The Odds Ratio in this case was 1.74. ^ Three scenarios based on the difference in the risk of HIV infection between the intervention and comparison group were used for computation of Cost-Utility Ratios: Base, worst and best-case scenario. The best-case scenario yielded cost-effective results for male participants and cost-saving results for female participants when using ethnicity-adjusted HIV prevalence. The scenario remained cost-effective for female participants when using the unadjusted HIV prevalence. ^ The challenge to the program is to devise approaches that can enhance benefits for male participants. If it is a threshold problem implying that male participants require more intensive programs for behavioral change, then programs should first be piloted among boys before being implemented across the board. If it is a reflection of gender differences, then we might have to go back to the drawing board and engage boys in focus group discussions that will help formulate more effective programs. Gender-blind approaches currently in vogue do not seem to be working. ^

Habitar al borde del agua : villas del siglo XX

Las casas del siglo XX construidas al borde del mar –escenario único y origen de su expresión- siguen la topografía del suelo que habitan en su descenso al agua, y organizan espacios que obtienen miradas al horizonte marino. El horizonte nos confronta a lo desconocido. La vista del mar incita al deseo de recorrerlo, al deseo de viajar. Con origen en el otium romano, la presencia del agua define un modo de vida apacible –epicúreo- que los viajeros de la arquitectura -que nos acompañan en la tesis- traducen en sus refugios más íntimos. Experimentan con los cambios en los conceptos y en las técnicas, que se trasladan fácilmente a la arquitectura de la casa al borde del agua desde los inicios del Movimiento Moderno. Sus espacios del habitar frente al mar nos permiten descubrir estrategias comunes en sus respuestas más modernas. El arquitecto ante el proyecto frente al mar llega a la ubicación elegida, mira hacia el horizonte, y desplazándose ladera arriba se coloca en un punto estratégico que elige; después, delante de su tablero, recorre el camino inverso, coloca el lugar y sobre él dibuja los elementos que configurarán los espacios de la casa buscando esa mirada al mar. Las situaciones y ubicaciones posibles son infinitas; se definen algunas consonancias espaciales comunes en los suelos que se ocupan debidas a la presencia del mar que asociamos entre sí. De la comparación entre todas las casas -emblemas del XX-, surgen múltiples variantes de la mirada y de espacios al abierto, y modos de fabricar entornos con criterios comunes para dominar la visión del mar. Interiores que se abren al panorama, espacios cuyas ventanas buscan su mirada en la extensión del horizonte, rescisiones y aperturas. Reconocemos condicionantes en el territorio a los que las villas responden, categorías arquitectónicas que dan respuesta frente al mar en la búsqueda del moderno, la topografía, la mirada y el espacio al abierto. Las casas comparten la idea del dominio del paisaje desde el punto más alto, y en algunos suelos se invierte la tipología por la topografía, confirmando así un criterio común basado en la lectura del suelo como consecuencia de la búsqueda del espacio de la mirada. Los espacios al abierto se significan en todas ellas, son espacios al -aire libre- abiertos, unos envueltos, otros porticados, puertas del horizonte que se abren al exterior, en el techo de la casa, otros cubiertos y abiertos, espacios entre interior y exterior, en plataformas con bancales o patios envolventes, recintos o habitaciones abiertas. Descubrimos un logro del XX en los espacios positivos o negativos que traducen o juegan con el entorno, que ocupan o sustraen de los contornos construidos y que obtienen espacios intermedios en la búsqueda de la relación con el mar. Las herramientas que se utilizan son los dibujos de los autores, de las casas visitadas, el elenco de viajeros y sus viajes, el conocimiento desde el estudio de los proyectos. A través de la comparación por aproximaciones parciales, los dibujos nos definen la mirada al mar, el modo de ocupación y la forma de relación con el paisaje. La arquitectura del habitar frente al mar en el XX, hecha para y por arquitectos, topografía el suelo y construye la mirada, fabricando espacios al abierto en la relación entre la casa y el entorno marítimo. ABSTRACT Houses of the 20th century built by the sea – a unique setting which gives rise to their expression – follow the topography of the land they occupy in its descent towards the sea, and they organize spaces which give views of the maritime horizon. The horizon brings us face to face with the unknown. The sea view provokes a desire to cross it, to travel. The presence of the sea defines a peaceful, epicurean way of life, with origins in the Roman otium, which architectural travellers – who accompany us through the thesis – translate into their most intimate retreats. They experiment with changes in concepts and techniques, which are easily transferred to the architecture of the seaside house since the beginnings of the Modern Movement. Their living spaces allow us to discover common strategies in the most modern responses. The architect with a seaside project arrives at the site, looks towards the horizon, then walks uphill and chooses a strategic point; then with his drawing board he retraces his steps, he sets the position and then draws in the elements that make up the house that seeks a sea view. The number of potential situations and locations is infinite; certain common spatial accordances are defined in land which is occupied due to the presence of the sea. Comparison of all the houses – 20th century emblems – throws up multiple variations of view and open spaces, and ways of creating settings with common criteria so as to command the vision of the sea. Interiors which open up to the panorama, spaces whose windows seek their view in the expanse of the horizon, openings and closures. We recognise determinant factors in the territory to which the villas respond, architectural categories which give a seaside solution to the search for the modern, the topography, the view, and the open space. The houses share the idea of dominating the landscape from the highest point, and in some areas typology and topography are inverted, thus confirming a common criteria based on the reading of the ground as a conse quence of the search for the view space. Open spaces stand out in all the villas – spaces open to the outdoor air - some are wrapped, some arcaded, doors to the horizon which open up to the exterior, on the roof of the house. There are open and covered spaces, spaces between the exterior and interior, on platforms with banks and surrounding patios, enclosures and open rooms. We discover an achievement of the 20th century in the positive and negative spaces which translate and play with the setting, which occupy or are extracted from built contours and which obtain intermediate spaces in the search for the relationship with the sea. The tools used are the author’s drawings of the houses visited, the cast of travelling companions and their travels, the knowledge gained from study of the projects. Through comparison by means of partial approaches, the drawings define the view of the sea, the occupation mode and the way of relating to the landscape. Architecture for living by the sea in the 20th century, carried out both by and for the architects, shapes the land and constructs the view, creating open spaces in the relationship between the house and the sea surroundings.

Las casualidades controladas : la primera visibilidad del cambio del paradigma moderno

Como no pocos proyectos, el origen de esta tesis es fruto de una casualidad. Hace unos años me topé en Londres, en la librería Walden Books del 38 de Harmood St., con una primera edición de la conocida monografía de Mies a cargo de Philip Johnson. El librito, en realidad catálogo de la exposición que en 1947 el MoMA de Nueva York dedicara a la obra de Mies Van der Rohe a los diez años del desembarco del arquitecto en Estados Unidos, tiene un tamaño de 10 x 7,5 pulgadas, es decir, la mitad del formato americano Crown (20x15 pulgadas), equivalente a 508 x 381 mm. Se imprimieron, en su primera tirada, editada por The Plantin Press, 12.000 ejemplares. Ese mismo año, con edición al cuidado de Reynal y Hitchcock, se publicaría la primera traducción al inglés de Cuando las catedrales eran blancas de Le Corbusier y una selección de poemas de Lorca, siete años después de su Poeta en Nueva York. En la monografía, en la página 109, aparece el conocido croquis de Mies Sketch for a glass house on a hillside. c. 1934, escasamente unas líneas, aunque precisas y llenas de matices, de la casa en una ladera que rápidamente nos remite a aquella primera propuesta de Saarinen para una casa en el aire, primero en 1941 en Pensilvania y después, en 1945, con Charles Eames, en Los Angeles, que nunca llegarían a construirse, sino en su aliteraciones posteriores realizadas por Harry Seidler (Julian Rose House, Wahroonga, Sydney, 1949), Philip Johnson (Leonhardt house, Long Island, Nueva York, 1956) o Craig Ellwood (Smith House, Crestwood Hills, 1958; Frank & Polly Pierson House, Malibú, 1962; Chamorro House, Hollywood Hills, 1963, o la serie Weekend House, con Gerald Horn, entre 1964 y 1970, hasta el magnífico Art Center College of Design de Pasadera, su puente habitado de 1977). El relato que da origen al texto discurre en un estricto período de tiempo, desde los primeros dibujos de la Case Study House nº8, dentro del programa promovido por John Entenza y su revista Arts & Architecture en California, realizados en el estudio de Saarinen en Bloomfield Hills, Michigan, hasta que el proyecto de la casa Eames finaliza cinco años después de acabar la obra en 1955, en la versión conocida, radicalmente distinta al proyecto original, cuando la pareja Charles y Ray Eames edita el corto House After Five Years of Living. La discusión original en torno a esta casita, o mejor, a las circunstancias, casualidades controladas, que rodean su construcción, se produce estrictamente cuando rastreamos aquellos invariantes que se mantienen en las dos versiones y las reconcilian. En este corto período de tiempo se producen en el proyecto una serie de decisiones que permiten descubrir, tanto en la forma como en el mismo proceso transformador del proyecto, en su obsesivo registro, en los nuevos referentes asumidos y propuestos, la primera visibilidad del cambio del paradigma moderno. Pero este momento germinal que cristaliza el paso a la postmodernidad no es inédito en la historia de la arquitectura americana. Así, el relato abre su ámbito temporal hasta un nuevo período de cincuenta años que arranca en 1893, año de la celebración en Chicago de la Exposición Internacional Colombina. En la White City de Hunt & McKim y del traidor Burham, Louis Sullivan construye su Golden Doorway en el pabellón de los Transportes. Aquella que visitará Adolf Loos antes de volver, renovado, a Viena; la misma que admirará André Bouillet, representante de la Union Centrale des Arts Decoratifs de Paris, y que deslumbrará en los museos de toda Europa, de París a Moscú en grandes fotografías y maquetas. Hasta que en Finlandia alguien muestra una de esas fotografías a un joven estudiante de diecinueve años en el Instituto Politécnico. Eliel Saarinen queda fascinado por la poderosa novedad de la imagen. Cuelga la fotografía frente a su tablero de dibujo, consciente de que la Golden Doorway, esa puerta de la aventura y la catarsis que Sullivan acuñaría como distintivo y que resolvería como único elemento complejo sus proyectos más maduros, desprovistos de todo ornamento; la misma que repetirían más tarde, con profundo reconocimiento, Ladovsky, Wright, Scarpa o Moneo, puerta dentro de puerta, fuelle y umbral, contenía, en sus propias palabras emocionadas, todo el futuro de la arquitectura. Desde ahí, pasando por el año 1910, momento de la huida de Wright a La Toscana y el descubrimiento de su arquitectura en Europa, entre otros por un joven Mies van der Rohe, meritorio en el estudio de Peter Behrens, a través del Wasmuth Portfolio; y así como algo después, en 1914, Schindler y en 1923 Neutra, harán el camino inverso, hasta que Mies les siga en 1937, animado por un Philip Johnson que había viajado a Europa en 1930, volviendo a 1945 y el inicio del programa Case Study House en California, hasta 1949, momento de la construcción de la CSH#8, y, por fin, al año 1955, after 5 years of living, en el que Julius Shulman fotografía la casa de Ray y Charles Eames en el prado de Chautauqua sobre las Pacific Palisades de Los Angeles, lanzando sus finas líneas amarillas hasta Alison y Peter Smithson y su tardomoderno heroico, hasta el primer Foster y su poético hightech y hasta el O-riginal Ghery, deconstruyendo el espacio esencial de su casa desde el espacio mismo, abiertas ya las puertas al nuevo siglo. Y en estos cambios de paradigma, desde el rígido eclecticismo de los estilos al lirismo moderno en el gozne secular y de ahí a la frivolidad, ligereza, exhibicionismo y oportunismo cultos del hecho postmoderno, hay algo que se mantiene invariante en los bandazos de la relación del hombre contemporáneo con su entorno. Como la escultura, que según Barnett Newman no es sino aquello contra lo que uno choca cuando retrocede para mirar un cuadro, en estos prístinos lugares, comunes y corrientes, recorrido, puerta, umbral, recinto y vacío, te topas con la arquitectura antes de darte cuenta de que es arquitectura. ABSTRACT As with many other projects, the origin of this doctoral thesis is the result of a chance. A few years ago I found in a bookstore in London, 38 Harmood st., Walden Books, a first edition of the well-known monograph about Mies by Philip Johnson. The tiny book, in fact a catalog of the exhibition that the MoMA of New York devoted to the work of Mies van der Rohe in 1947, ten years after his landing in the United States, has a size of 10 x 7.5 inches, that is, half of Crown American format (20 x 15 inches), equivalent to 508 x 381 mm. In the first printing, published by The Plantin Press, 12,000 copies were released. That same year, produced by Reynal and Hitchcock, both the first English translation of When the cathedrals were white by Le Corbusier and a selection of poems by Lorca were published, seven years after his Poet in New York. Inside the book, the famous drawing from Mies Sketch for a glass house on a hillside c. 1934 appears on page 109, barely a few lines, precise and nuanced though, the house on a hillside that quickly reminds us of the proposals of Eero Saarinen for a house in the air, first in 1941, in Pennsylvania, and later, in 1945, with Charles Eames, in Los Angeles, that would never be built, but in their later alliterations made by Harry Seidler (Julian Rose House, Wahroonga, Sydney, 1949), Philip Johnson (Leonhardt house, Long Island, New York, 1956) or Craig Ellwood (Smith House, Crestwood Hills, 1958; Frank Pierson & Polly House, Malibu, 1962, Chamorro House, Hollywood Hills, 1963, or the Weekend House series, with Gerald Horn, between 1964 and 1970, to the magnificent Art Center College of Design Pasadena, the inhabited bridge, in 1977). The story that gives rise to the text flows in a short amount of time, from the first drawings of the Case Study House No. 8, within the program promoted by John Entenza and his magazine Arts & Architecture in California, made in the study of Saarinen in Bloomfield Hills, Michigan, until the project of the Eames house is completed five years after finishing the construction in 1955, in the final version we know, radically different from the initial state, when the couple, Charles and Ray, published the film House after Five Years of Living. The original discussion around this house, or better, about the circumstances, controlled coincidences, regarding its construction, appears when one takes account of those that remain, the invariants, in the two versions, drawn and built, which precisely allow the reconciliation between both projects. In this short period of time a series of decisions made in the transformation process of the project reveal, in the obsessive record made by Charles Eames and in the new proposed references, the first visibility of the changing of the modern paradigm. But this germinal moment that crystallizes the transition to postmodernism is not unprecedented in the history of American architecture. So, the story opens its temporal scope to a fifty-year period that started in 1893, date of the celebration of the Chicago World´s Columbian Exposition. In the White City by Hunt & McKim and Burnham, the traitor, Louis Sullivan builds his Golden Doorway in the Transportation Building. That visited by a renovated Adolf Loos before his coming back to Vienna; the same that André Bouillet, Head of the Union Centrale des Arts Decoratifs in Paris, admired and dazzled in museums all over Europe, from Paris to Moscow, in large photographs and models. Until someone in Finland showed one of those photos to a young nineteen-years-old student at the Polytechnic Institute. Eliel Saarinen became fascinated by the powerful new image: he hanged the picture in front of his drawing board, aware that the Golden Doorway, that door of adventure and catharsis Sullivan coined as distinctive and as a single complex element which would solve their most mature projects, devoid of all ornament; the same that would repeat later, with deep appreciation, Ladovsky, Wright, Scarpa, or Moneo, a door inside a door, a threshold, a gap that contained, in its own moving words, the whole future of architecture. From there, through 1910, when Wright's flight to Tuscany allows Europe to discover his architecture, including a young Mies van der Rohe, meritorious in the studio of Peter Behrens, via the Wasmuth Portfolio; and as a little bit later, in 1914, Schindler and Neutra in 1923, made the travel in opposite direction, until Mies follows them in 1937, led by a Philip Johnson who had traveled to Europe in 1930, we return to 1945 and the beginning of the program Case Study House in California, and from 1949, when construction of the CSH # 8 begins, and finally, to 1955, after five years of living, when Julius Shulman photographs the inside of the house with Ray and Charles Eames, and all their belongins, at the Chautauqua meadows on Pacific Palisades in Los Angeles, launching its fine yellow lines to Alison and Peter Smithson and his heroic late modern, up to the first Foster and his poetic hightech and even the O-riginal Gehry, deconstructing the essential space of his home from the space itself, opening the doors to the new century. And these paradigm shifts, from the hard eclectic styles to modern secular lyricism in the hinge and then overcoming the cultured frivolity, lightness, exhibitionism, and opportunism of the postmodern skeptical focus, something remains intense, invariant in the lurching relationship of contemporary man and his environment. As the sculpture, which according to Barnett Newman is what you bump into when you back up to see a painting, in these pristine, ordinary places, promenade, door, threshold, enclosure and emptiness, you stumble upon the architecture even before realizing that it is architecture.

Um conto, um canto, um encanto: a história, o mapa, a música em Belo Horizonte

O presente trabalho pretende ser uma contribuição no campo da etnomusicologia, e resulta de um estudo e pesquisa de campo realizada na cidade de Belo Horizonte, capital do estado de Minas Gerais, Brasil. Belo Horizonte é uma cidade “inventada”, assim como Brasília, a capital federal. Enquanto cidade, Belo Horizonte foi desenhada, projetada, nasceu de uma prancheta e foi oficialmente inaugurada em 12 de dezembro de 1897. Nesta tese tem como objetivo compreender e demonstrar como as transformações sociais e espaciais foram provocadas pelo acontecimento musical. Defendo a posição que o entendimento do que denomino Acontecimento Musical permite perceber o potencial da música de reorganizar normas, inicialmente defendidas pelos idealizadores da cidade, da utilização e ocupação dos lugares e espaços, e construindo, pela prática musical, uma nova cartografia da cidade, que se impõe a cartografia oficialmente idealizada, resultando em uma Cartografia Musical de Belo Horizonte.

Predicting the performance of passenger ships using computer simulation

When designing a new passenger ship or naval vessel or modifying an existing design, how do we ensure that the proposed design is safe from an evacuation point of view? In the wake of major maritime disasters such as the Herald of Free Enterprise and the Estonia and in light of the growth in the numbers of high density, high-speed ferries and large capacity cruise ships, issues concerned with the evacuation of passengers and crew at sea are receiving renewed interest. In the maritime industry, ship evacuation models are now recognised by IMO through the publication of the Interim Guidelines for Evacuation Analysis of New and Existing Passenger Ships including Ro-Ro. This approach offers the promise to quickly and efficiently bring evacuation considerations into the design phase, while the ship is "on the drawing board" as well as reviewing and optimising the evacuation provision of the existing fleet. Other applications of this technology include the optimisation of operating procedures for civil and naval vessels such as determining the optimal location of a feature such as a casino, organising major passenger movement events such as boarding/disembarkation or restaurant/theatre changes, determining lean manning requirements, location and number of damage control parties, etc. This paper describes the development of the maritimeEXODUS evacuation model which is fully compliant with IMO requirements and briefly presents an example application to a large passenger ferry.

A multi-touch notice board fostering social interaction

We report on an alternative OCGM interface for a bulletin board, where a user can pin a note or a drawing, and actually shares contents. Exploiting direct and continuous manipulations, opposite to discrete gestures, to explore containers, the proposed interface supports a more natural and immediate interaction. It manages also the presence of different simultaneous users, allowing for the creation of local multimedia contents, the connection to social networks, providing a suitable working environment for cooperative and collaborative tasks in a multi-touch setup, such as touch-tables, interactive walls or multimedia boards

Report for the British Board of Film Classification on viewers of the Lord of the Rings, aged under 16

This is a report on what can be learnt from our world dataset about viewers of The Lord of the Rings who were aged under 16. In this report, I draw both on the world set, and on the UK subset, sometimes drawing comparisons between them. The reason for using both is that, obviously, the world set is so much larger (comprising 24,739 in toto, with 2475 under 16), but the UK set (comprising 3115 in toto, and 306 under 16s) allows us to explore both some of the specificities of responses here, the qualitative meaning of some responses (given we worked in 14 languages, many are inaccessible to us for analysis), and of course their relations to the quantitative patterns that emerge.

From activity to active learning: drawing and dialogue interaction in virtual learning environments for computer-supported collaborative work in design.

Virtual learning environments (VLEs) would appear to be particular effective in computer-supported collaborative work (CSCW) for active learning. Most research studies looking at computer-supported collaborative design have focused on either synchronous or asynchronous modes of communication, but near-synchronous working has received relatively little attention. Yet it could be argued that near-synchronous communication encourages creative, rhetorical and critical exchanges of ideas, building on each other’s contributions. Furthermore, although many researchers have carried out studies on collaborative design protocol, argumentation and constructive interaction, little is known about the interaction between drawing and dialogue in near-synchronous collaborative design. The paper reports the first stage of an investigation into the requirements for the design and development of interactive systems to support the learning of collaborative design activities. The aim of the study is to understand the collaborative design processes while sketching in a shared white board and audio conferencing media. Empirical data on design processes have been obtained from observation of seven sessions with groups of design students solving an interior space-planning problem of a lounge-diner in a virtual learning environment, Lyceum, an in-house software developed by the Open University to support its students in collaborative learning.

Gender diversity and board performance: women's experiences and perspectives

Despite considerable progress that organizations have made during the past 20 years to increase the representation of women at board level, they still hold few board seats. Drawing on a qualitative study involving 30 companies with women directors in the United Kingdom, the United States, and Ghana, we investigate how the relationship between gender in the boardroom and corporate governance operates. The fi ndings indicate that the presence of a minority of women on the board has an insignifi cant effect on board performance. Yet the chairperson’s role is vital in leading the change for recruiting and evaluating candidates and their commitment to the board with diversity and governance in mind. Our study also sheds light on the multifaceted reasons why women directors appear to be resisting the discourse of gender quotas.

Balancing Control and Coaching in CSO Governance : A Paradox Perspective on Board Behavior

How can governance of civil society organizations be conceptualized more adequately by accounting for the dual and simultaneous requirements of controlling and coaching in board behavior? Empirically, we seem to agree that effective governance of a civil society organization is crucial to its sustained viability. Conceptually, however, we observe a lack of consensus on how to best conceptualize CSO governance. By critically juxtaposing two major theoretical lenses to conceptualize governance, namely agency and stewardship theory, we identify a number of challenges conceptualizing board-management relations that deserve our attention. While agency theory privileges controlling behavior, stewardship theory emphasizes the coaching behavior of boards. The purpose of this paper is to offer a concept of governance that is informed by a paradox perspective advancing a subtler, more adequate conceptualization of board governance that accounts for the often conflicting demands on CSO governance. Drawing on a longitudinal interpretive case study, we exemplify our propositions empirically. The paper concludes with discussing the implications of our argument for CSO governance research and practice.

Assessing the relationship between board composition and nonprofit hospital financial performance from a multi-theoretic perspective

This dissertation assesses the relationship between board composition and financial performance for the top 71 major nonprofit hospitals in the United States during the period 2004-2009. The underlying data were collected from copies of IRS Form 990 available at http://www.guidestar.org . The dissertation investigates five factors: board size, board independence (percentage of outsiders), number of MDs, CEO succession and CEO compensation. And it evaluates the results within a multi-theoretic framework drawing on agency theory, resource dependence theory, institutional theory and social network theory. Corporate governance literature suggests that board composition has an important impact on firm financial performance. This dissertation examines whether the same may be true for nonprofit hospitals. The results should help hospital executives make better governance decisions during trying economic times.^
