Linking early design decisions across multiple disciplines

The early stages of the building design process are when the most far reaching decisions are made regarding the configuration of the proposed project. This paper examines methods of providing decision support to building designers across multiple disciplines during the early stage of design. The level of detail supported is at the massing study stage where the basic envelope of the project is being defined. The block outlines on the building envelope are sliced into floors. Within a floor the only spatial divisions supported are the “user” space and the building core. The building core includes vertical transportation systems, emergency egress and vertical duct runs. The current focus of the project described in the paper is multi-storey mixed use office/residential buildings with car parking. This is a common type of building in redevelopment projects within and adjacent to the central business districts of major Australian cities. The key design parameters for system selection across the major systems in multi-storey building projects - architectural, structural, HVAC, vertical transportation, electrical distribution, fire protection, hydraulics and cost – are examined. These have been identified through literature research and discussions with building designers from various disciplines. This information is being encoded in decision support tools. The decision support tools communicate through a shared database to ensure that the relevant information is shared across all of the disciplines. An internal data model has been developed to support the very early design phase and the high level system descriptions required. A mapping to IFC 2x2 has also been defined to ensure that this early information is available at later stages of the design process.

The increasing importance of serviced offices as a competing land use in global cities

Once considered a relatively low key land use in central business districts, the number of serviced offices has increased dramatically in recent years. The factors driving the demand for serviced offices have changed, and the suppliers of this service have reacted quickly to meet these needs. This trend has been assisted by the expansion of a select number of multi-national companies that specialise in the provision of serviced offices, available in a flexible range of office types and costs.
This paper considers the reasons behind the rapid growth in the serviced office market, and examines the role of both the user and the provider. Attention is focused on the global marketplace and how these changes have been transformed into the Australian central business districts. The information will be of benefit to property analysts, developers and investors, especially when seeking an alternative use of existing traditional office accommodation.

Glaucoma and on-road driving performance

PURPOSE. To investigate the on-road driving performance of patients with glaucoma.

METHODS. The sample comprised 20 patients with glaucoma and 20 subjects with normal vision, all licensed drivers, matched for age and sex. Driving performance was tested over a 10-km route incorporating 55 standardized maneuvers and skills through residential and business districts of Halifax, Nova Scotia, Canada. Testing was conducted by a professional driving instructor and assessed by an occupational therapist certified in driver rehabilitation, masked to participant group membership and level of vision. Main outcome measures were total number of satisfactory maneuvers and skills, overall rating, and incidence of at-fault critical interventions (application of the dual brake and/or steering override by the driving instructor to prevent a potentially unsafe maneuver). Measures of visual function included visual acuity, contrast sensitivity, and visual fields (Humphrey Field Analyzer; Carl Zeiss Meditec, Inc., Dublin, CA; mean deviation [MD] and binocular Esterman points).

RESULTS. There was no significant difference between patients with glaucoma (mean MD = −1.7 dB [SD 2.2] and −6.5 dB [SD 4.9], better and worse eyes, respectively) and control subjects in total satisfactory maneuvers and skills (P = 0.65), or overall rating (P = 0.60). However, 12 (60%) patients with glaucoma had one or more at-fault critical interventions, compared with 4 (20%) control subjects (odds ratio = 6.00, 95% CI, 1.46–24.69; higher still after adjustment for age, sex, medications and driving exposure), the predominant reason being failure to see and yield to a pedestrian. In the glaucoma group, worse-eye MD was associated with the overall rating of driving (r = 0.66, P = 0.002).

CONCLUSIONS. This sample of patients with glaucoma with slight to moderate visual field impairment performed many real-world driving maneuvers safely. However, they were six times as likely as subjects with normal vision to have a driving instructor intervene for reasons suggesting difficulty with detection of peripheral obstacles and hazards and reaction to unexpected events.

Procesos de dualización en la sociedad de la información: algunas polémicas públicas de índole tecnológica

La tecnología ha cambiado el mundo, pero las consecuencias de estos cambios en la sociedad no siempre se han pronosticado bien. Las Tecnologías de la Información transformaron el método de producción industrial. La nueva industria produce ideas y conceptos, no objetos. Este cambio ha dado como resultado una sociedad dualizada, ha desaparecido gran parte de la clase media y han aumentado las diferencias entre la clase alta y la baja. Las exigencias educativas de los nuevos puestos de trabajo innovadores son superiores a los de la industria tradicional, pero inferiores en los puestos de trabajo de producción. Además, el número de puestos de trabajo disponibles de este tipo es menor que en la industria tradicional, se necesita menos mano de obra, los procesos se pueden automatizar, las tareas mecánicas se aprenden en poco tiempo y son trabajos temporales, cuyo número dependerá de la demanda global. Para que el proceso de innovación funcione, las empresas se reúnen en las zonas financieras de grandes ciudades, como Nueva York o Londres, que fueron las primeras con acceso a las redes de telecomunicación. De esta manera se producen sinergias que contribuyen a mejorar el proceso innovador global. Estas ideas y conceptos que cambian el mundo necesitan de este entorno de producción, que no puede ser replicado, y son tan importantes que su acceso está restringido para la mayor parte del mundo por distintos mecanismos de control. El despliegue de las redes de telecomunicaciones inalámbricas ha sido enorme en los últimos años. El cliente busca llamar desde cualquier lugar y llevar un acceso a Internet en teléfono móvil. Para conseguirlo, las operadoras de telefonía móvil necesitan poner antenas de telefonía móvil en las ciudades, pero la instalación cerca de edificios no está siendo fácil. Pocos quieren tener una antena cerca por los problemas de salud de las personas que padecen los que ya viven o trabajan cerca de una. Los efectos del electromagnetismo en los seres humanos no están claros y provocan desconfianza hacia las antenas. La digitalización de los contenidos, que ha sido necesaria para transmitir contenido en Internet, permite que cualquier persona con un ordenador y una conexión a Internet pueda publicar un disco, una película o un libro. Pero esa persona también puede copiar los originales y enviarlos a cualquier lugar del mundo sin el permiso del autor. Con el fin de controlar la copia no autorizada, los derechos de autor se están usando para cambiar leyes e incluir sistemas de censura en Internet. Estos sistemas permiten a los autores eliminar el contenido ilegal, pero también pueden ser usados para censurar cualquier tipo de información. El control de la información es poder y usarlo de una manera o de otra afecta a todo el planeta. El problema no es la tecnología, que es solo una herramienta, es la forma que tienen los gobiernos y las grandes empresas de usarlo. Technology has changed the world, but the consequences of these changes in society have not always been well predicted. The Information Technology transformed the industrial production method. The new industry produces ideas and concepts, not objects. This change has resulted in a society dualized, most of the middle class has disappeared and the differences between high and low class have increased. The educational requirements of new innovative jobs are higher than the ones of the traditional industry, but lower in production jobs. Moreover, the number of available jobs of this type is lower than in the traditional industry, it takes less manpower, processes can be automated, mechanical tasks are learned in a short time and jobs are temporary, whose number depends on global demand. For the innovation process works, companies meet in the business districts of large cities, like New York or London, which were the first with access to telecommunications networks. This will produce synergies that improve the overall innovation process. These ideas and concepts that change the world need this production environment, which cannot be replicated, and are so important that their access is restricted to most of the world by different control mechanisms. The deploy of wireless telecommunications networks has been enormous in recent years. The client seeks to call from anywhere and to bring Internet access in his mobile phone. To achieve this, mobile operators need to put cell towers in cities, but the installation near buildings is not being easy. Just a few want to have an antenna closely because of the health problems suffered by people who already live or work near one. The effects of electromagnetism in humans are unclear and cause distrust of antennas. The digitization of content, which has been necessary to transmit Internet content, allows anyone with a computer and an Internet connection to be able to publish an album, a movie or a book. But that person can also copy the originals and send them anywhere in the world without the author's permission. In order to control the unauthorized copying, copyright is being used to change laws and include Internet censorship systems. These systems allow authors to eliminate illegal content, but may also be used to censor any information. The control of knowledge is power and using it in one way or another affects the whole planet. The problem is not technology, which is just a tool, but the way that governments and large corporations use it.
