Sitting ducks.

Cada día, en la colosal Duck Factory, se produce un constante abastecimiento de patos recién salidos del cascarón que se deslizan por la cadena de montaje, y cuyo destino son los platos de hambrientos caimanes. Un día, sin embargo, uno de esos huevos rueda fuera de la cadena de montaje. Un trabajador de la fábrica descubre al pato y se lo lleva a su casa metido en la fiambrera. El adorable pato se gana poco a poco a su anfitrión caimán. Pero en este mundo de caimanes, comedores de patos, puede sobrevivir esta amistad.

L'esquerda ecològica: residus industrials i geografia humana

L'article presenta una visió global de la problemàtica dels residus industrials des d'una doble perspectiva que destaca el caràcter socioterritorial dels impactes, associats a la seva presència en el medi, i els conflictes que s'esdevenen entorn a les opcions de gestió actualment vigents. Després d'examinar els residus en relació amb la producció industrial, i la producció i 'eliminació', dels residus industrials des de la dimensió territorial, es fa un repàs de les polítiques de gestió, sobre la base de diferents països productors, i s'estudien les implicacions sociopolítiques dels models de gestió, tot centrant-se en l'analisi de les iniciatives ciutadanes alemanyes i de les mobilitzacions a Catalunya en resposta al 'Pla Director per a la Gestió dels Residus Industrials a Catalunya'. A les conclusions s'enceta una reflexió a l'entorn de la recerca en Geografia Humana i l'anàlisi dels residus industrials, i es plantegen les implicacions teòriques i epistemològiques de cara a una visió social dels problemes ambientals

Harinera La Montserrat (1898-1936). Aproximación a la historia empresial de los Ensesa de Girona (c. 1880-c. 1989)

Després d'esbossar la trajectòria del grup empresarial dels Ensesa (la farinera, la metal·lúrgica Batlle, Solés i Cia, el Garatge Callicó, Indústries Químiques Tartàriques, la ciutat-jardí de S'Agaró, Suberolita, etc), la recerca s'orienta especialment cap a l'estudi del sistema d'informació comptable de "La Montserrat", que posa en relleu les característiques econòmiques, financeres i patrimonials de l'empresa. Des del principi, les activitats empresarials dels Ensesa tenen dimensions catalanes, espanyoles i internacionals, que s'amplien i diversifiquen molt ràpidament durant el primer terç del segle XX, en especial amb "els Químics" i la zona residencial de S'Agaró, on conflueixen la burgesia de Girona, Barcelona i el turisme de luxe. La seva adscripció a la burgesia catalanista sembla ser precisament el motiu de l'expedient de Responsabilitats Polítiques que els varen incoar al 1939-1940, però, absolts, recuperen les propietats que els havien estat col·lectivitzades durant la guerra civil, fins que a principis dels anys vuitanta procedeixen a la liquidació i venda de les indústries del grup empresarial.

Avaliação de riscos e desenvolvimento de equipamento anti-queda para acesso vertical a espaços confinados

Na fábrica da EPAL, em Vale da Pedra, o risco de queda em altura no acesso vertical a espaços confinados, foi avaliado como sendo aceitável mediante a adoção de medidas de controlo que não existiam, ou que não eram adequadas, ou ainda que não eram utilizadas. Para responder a este problema, foi concebido, desenvolvido e ensaiado um inovador dispositivo portátil anti-queda. Este previne a queda no acesso entre o pavimento e os primeiros degraus de aberturas verticais conducentes a espaços confinados. Além da função preventiva, também pode fazer parte da proteção anti-queda, como ponto de ancoragem dos equipamentos de proteção contra quedas. Os ensaios realizados revelaram que, em comparação com as alternativas pré-fabricadas disponíveis, esta solução é mais adequada para prevenir quedas, por se adaptar a múltiplas configurações de acesso, com um dispositivo relativamente leve, fácil de transportar e de aplicar, estável e resistente. / In EPAL factory in Vale da Pedra, the risk of falling from a height in the vertical access to confined spaces, was evaluated as being acceptable by the adoption of control measures that did not exist, or were not suitable, or were not used. To respond to this problem, an innovative portable anti-falling device was designed, developed and tested. This prevents falling in access between the ground and the first steps of vertical openings leading to confined spaces. In addition to the preventive function, it can also be part of the fall-arrest protection, as anchor point of fall protection equipment. The tests revealed that, in comparison with the prefabricated alternatives available, this solution is best suited to prevent falls, due to its adaptability to multiple access settings, with a relatively light device, easy to carry and to use, stable and resistant.

A project managed by a multi disciplinary practice: a systems based case study.

The technique of linear responsibility analysis is used for a retrospective case study of a private industrial development consisting of an engineering factory and offices. A multi-disciplinary professional practice was used to manage and design the project. The organizational structure adopted on the project is analysed using concepts from systems theory which are included in Walker's theoretical model of the structure of building project organizations (Walker, 1981). This model proposes that the process of buildings provision can be viewed as systems and sub-systems which are differentiated form each other at decision points. Further to this, the sub-systematic analysis of the relationship between the contributors gives a quantitative assessment of the efficiency of the organizational structure used. There was a high level of satisfaction with the completed project and this is reflected by the way in which the organization structure corresponded to the model's proposition. However, the project was subject to string environmental forces which the project organization was not capable of entirely overcoming.

Process planning methodology: dynamic short-term planning for off-site construction in Slovenia

Planning is a vital element of project management but it is still not recognized as a process variable. Its objective should be to outperform the initially defined processes, and foresee and overcome possible undesirable events. Detailed task-level master planning is unrealistic since one cannot accurately predict all the requirements and obstacles before work has even started. The process planning methodology (PPM) has thus been developed in order to overcome common problems of the overwhelming project complexity. The essential elements of the PPM are the process planning group (PPG), including a control team that dynamically links the production/site and management, and the planning algorithm embodied within two continuous-improvement loops. The methodology was tested on a factory project in Slovenia and in four successive projects of a similar nature. In addition to a number of improvement ideas and enhanced communication, the applied PPM resulted in 32% higher total productivity, 6% total savings and created a synergistic project environment.

Autonomous ship collision free trajectory navigation and control algorithms

A new autonomous ship collision free (ASCF) trajectory navigation and control system has been introduced with a new recursive navigation algorithm based on analytic geometry and convex set theory for ship collision free guidance. The underlying assumption is that the geometric information of ship environment is available in the form of a polygon shaped free space, which may be easily generated from a 2D image or plots relating to physical hazards or other constraints such as collision avoidance regulations. The navigation command is given as a heading command sequence based on generating a way point which falls within a small neighborhood of the current position, and the sequence of the way points along the trajectory are guaranteed to lie within a bounded obstacle free region using convex set theory. A neurofuzzy network predictor which in practice uses only observed input/output data generated by on board sensors or external sensors (or a sensor fusion algorithm), based on using rudder deflection angle for the control of ship heading angle, is utilised in the simulation of an ESSO 190000 dwt tanker model to demonstrate the effectiveness of the system.

Conceptualizing change in the Portuguese footwear industry: regional voices and cognitive spaces of agency

Expanding national services sectors and global competition aggravate current and perceived future market pressures on traditional manufacturing industries. These perceptions of change have provoked a growing intensification of geo-political discourses on technological innovation and ‘learning’, and calls for competency in design among other professional skills. However, these political discourses on innovation and learning have paralleled public concerns with the apparent ‘growth pains’ from factory closures and subsequent increases in unemployment, and its debilitating social and economic implications for local and regional development. In this respect the following investigation sets out to conceptualize change through the complementary and differing perceptions of industry and regional actors’ experiences or narratives, linking these perceptions to their structure-determined spheres of agent-environment interactivity. It aims to determine whether agents’ differing perceptions of industry transformation can have a role in the legitimization of their interests in, and in sustaining their organizational influence over the process of industry-regional transformation. It argues that industry and regional agent perceptions are among the cognitive aspects of agent-environment interactivity that permeate agency. It stresses agents’ ability to reason and manipulate their work environments to preserve their self-regulating interests in, and task representative influence over the multi-jurisdictional space of industry-regional transformation. The contributions of this investigation suggest that agents’ varied perceptions of industry and regional change inform or compete for influence over the redirection of regional, industry and business strategies. This claim offers a greater appreciation for the reflexive and complex institutional dimensions of industry planning and development, and the political responsibility to socially just forms of regional development. It positions the outcomes of this investigation at the nexus of intensifying geo-political discourses on the efficiency and equity of territorial development in Europe.

A Guide to Office Clerical Time Standards

A Guide to Office Clerical Time Standards is an instructional performance piece based on a corporate manual from 1960. The pamphlet is focused on the time necessary for the accomplishment of minute labour procedures in the office, from the depressing and releasing of typewriter keys to the opening and closing of filing cabinet drawers. In the performance, seven costumed performers represent the different levels of management and employment while performing the actions described in the guide, accompanied by a live musical score. There has been much discussion of the changes to work in the west following the decline of post-Fordist service sector jobs. These increasingly emphasise the specificity of employees’ knowledge and cognitive skill. However, this greater flexibility and creativity at work has been accompanied by an opposite trajectory. The proletarisation of white collar work has given rise to more bureaucracy, target assessment and control for workers in previously looser creative professions, from academia to the arts. The midcentury office is the meeting point of these cultures, where the assembly line efficiency management of the factory meets the quantifying control of the knowledge economy. A Guide to Office Clerical Time Standards explores the survival of one regime into its successor following the lines of combined and uneven development that have turned the emancipatory promise of immaterial labour into the perma-temp hell of the cognitariat. The movement is accompanied by a score of guitar, bass and drums, the componenets of the rock ‘n’ roll music that rose from the car factories of the motor city and the cotton fields of the southern states to represent the same junction of expression and control.

Modeling growth strategy in a biotechnology startup firm

The top managers of a biotechnology startup firm agreed to participate in a system dynamics modeling project to help them think about the firm's growth strategy. The article describes how the model was created and used to stimulate debate and discussion about growth management. The paper highlights several novel features about the process used for capturing management team knowledge. A heavy emphasis was placed on mapping the operating structure of the factory and distribution channels. Qualitative modeling methods (structural diagrams, descriptive variable names, and friendly algebra) were used to capture the management team's descriptions of the business. Simulation scenarios were crafted to stimulate debate about strategic issues such as capacity allocation, capacity expansion, customer recruitment, customer retention, and market growth, and to engage the management team in using the computer to design strategic scenarios. The article concludes with comments on the impact of the project.

Software evolution: a graph based model

A model based on graph isomorphisms is used to formalize software evolution. Step by step we narrow the search space by an informed selection of the attributes based on the current state-of-the-art in software engineering and generate a seed solution. We then traverse the resulting space using graph isomorphisms and other set operations over the vertex sets. The new solutions will preserve the desired attributes. The goal of defining an isomorphism based search mechanism is to construct predictors of evolution that can facilitate the automation of ’software factory’ paradigm. The model allows for automation via software tools implementing the concepts.
