Complexities Inherent (complexity + inherent)
Selected AbstractsMutual expectations: a study of the three-way relationship between employment agencies, their client organisations and white-collar agency ,temps'INDUSTRIAL RELATIONS JOURNAL, Issue 1 2004Janet Druker ABSTRACT This paper examines the mutual expectations of employment agencies, the temporary workers who are placed by them and the client or host companies with whom they are placed. It considers the ambiguities and complexities inherent in the psychological contracts of agency temps, pointing to positive dimensions of the agency relationship with temps coupled with a tough transactional regime. In periods of uncertainty agency temping provided individuals with an illusion of freedom and control. [source] Multiscale modeling of impact on heterogeneous viscoelastic solids containing evolving microcracksINTERNATIONAL JOURNAL FOR NUMERICAL METHODS IN ENGINEERING, Issue 4 2010Flavio V. Souza Abstract Multiscale computational techniques play a major role in solving problems related to viscoelastic composites due to the complexities inherent to these materials. In this paper, a numerical procedure for multiscale modeling of impact on heterogeneous viscoelastic solids containing evolving microcracks is proposed in which the (global scale) homogenized viscoelastic incremental constitutive equations have the same form as the local-scale viscoelastic incremental constitutive equations, but the homogenized tangent constitutive tensor and the homogenized incremental history-dependent stress tensor at the global scale depend on the amount of damage accumulated at the local scale. Furthermore, the developed technique allows the computation of the full anisotropic incremental constitutive tensor of viscoelastic solids containing evolving cracks (and other kinds of heterogeneities) by solving the micromechanical problem only once at each material point and each time step. The procedure is basically developed by relating the local-scale displacement field to the global-scale strain tensor and using first-order homogenization techniques. The finite element formulation is developed and some example problems are presented in order to verify the approach and demonstrate the model capabilities. Copyright © 2009 John Wiley & Sons, Ltd. [source] Euclid: Strategic alternative assessment matrixJOURNAL OF MULTI CRITERIA DECISION ANALYSIS, Issue 2 2002Madjid Tavana Abstract The vast amount of information that must be considered to solve inherently ill-structured and complex strategic problems creates a need for tools to help decision makers (DMs) recognize the complexity of this process and develop a rational model for strategy evaluation. Over the last several decades, a philosophy and a body of intuitive and analytical methods have been developed to assist DMs in the evaluation of strategic alternatives. However, the intuitive methods lack a structured framework for the systematic evaluation of strategic alternatives while the analytical methods are not intended to capture intuitive preferences. Euclid is a simple and yet sophisticated multiobjective value analysis model that attempts to uncover some of the complexities inherent in the evaluation of strategic alternatives. The proposed model uses a series of intuitive and analytical methods including environmental scanning, the analytic hierarchy process (AHP), subjective probabilities, and the theory of displaced ideal, to plot strategic alternatives on a matrix based on their Euclidean distance from the ideal alternative. Euclid is further compared to the quantitative strategic planning matrix (QSPM) in a real world application. The information provided by the users shows that Euclid can significantly enhance decision quality and the DM's confidence. Euclid is not intended to replace the DMs, rather, it provides a systematic approach to support, supplement, and ensure the internal consistency of their judgments through a series of logically sound techniques.

[source] Moving methods: constructing emotionally poignant geographies of HIV in Auckland, New ZealandAREA, Issue 3 2010Jason Myers As we strive to fully understand the meanings different people create and attach to places, we need methods that allow multiple and subjective experiences of place to be critically uncovered and understood. This paper reflects on the employment of photography and caption-writing in research with HIV-positive men-who-have-sex-with-men in Auckland, New Zealand. These methods contributed in constructing an argument that the acquisition of HIV affected experiences of both literal place as well as place-in-the-world for the research participants. With the ability to move with participants (both physically and emotionally), the methods helped to illustrate a range of (re)negotiations of self and place beyond diagnosis. Moreover, engagement with these methods resulted in personal gain for many of the participants in the research. It is concluded that the continued (re)development of creative (ethically sound) qualitative methods can add rigour to our attempts at representing the complexities inherent in the relationships between people and the places they occupy. [source] L'ajustement mutuel dans le fonctionnement organique du système multiorganisationnel d'aide et de services aux sans-abri de MontréalCANADIAN PUBLIC ADMINISTRATION/ADMINISTRATION PUBLIQUE DU CANADA, Issue 1 2009Alain Dupuis Sommaire : Notre étude de l'organisation du secteur de l'aide et des services aux sans-abri à Montréal Centre met en lumière un système multiorganisationnel de services de santé et de services sociaux qui n'est pas intégré hiérarchiquement dans son ensemble et qui n'est pas soumis à une « entente de gestion et d'imputabilité» globale propre à une gestion fondée sur la normalisation des résultats. L'étude présente un système d'ensemble de type « organique » plutôt que bureaucratique, largement fondé sur des ajustements mutuels entre les nombreux acteurs publics et « communautaires » de ce secteur. La coordination des services se réalise alors essentiellement dans les interactions entre les intervenants alors qu'ils accomplissent leur travail, et ce avec le soutien des gestionnaires. À l'aide de nombreux extraits d'entrevues, nous étudions le fonctionnement de ce système « organique » sous la forme de trois catégories de processus d'ajustement mutuel qui se superposent et se complètent pour assurer la valeur des services : disjoint unilatéral, conjoint bilatéral et conjoint multilatéral. Selon les sciences de l'organisation, un tel système est potentiellement mieux adaptéà composer avec la complexité des connaissances et des valeurs caractéristiques des services humains, qu'un à système formellement intégré et contrôlé par des règles, des indicateurs et des cibles quantifiables. Abstract: This study of the organization of the sector dedicated to providing aid and services to the homeless in Central Montreal reveals a multiorganizational health and social services system that is neither hierarchically integrated as a whole nor subject to a comprehensive "management and accountability agreement" specific to standardized results-based management. The study details a comprehensive system that is "organic," rather than bureaucratic, and broadly organized based on mutual adjustments among the numerous public and "community" practitioners in this sector. The coordination of services is therefore essentially achieved through the interaction of the workers as they perform their jobs, with the support of management. This study draws on a number of extracts from interviews to examine how this "organic" system operates, in the form of three distinct processes of mutual adjustment that are superimposed and complementary to ensure the value of the services: "unilateral disjoined,""bilateral joined" and "multilateral joined." According to organizational science, this type of system is potentially more likely to address the complexities inherent in the knowledge and values that are characteristic of human services than a formally integrated system that is controlled by rules, indicators and quantifiable targets. [source] TOWARDS A UNIFORM CONCEPT FOR THE COMPARISON AND EXTRAPOLATION OF ROCKWALL RETREAT AND ROCKFALL SUPPLYGEOGRAFISKA ANNALER SERIES A: PHYSICAL GEOGRAPHY, Issue 1 2007MICHAEL KRAUTBLATTER ABSTRACT. Rates of rockwall retreat and rockfall supply are fundamental components of sediment budgets in steep environments. However, the standard procedure of referencing rockwall retreat rates using only lithology is inconsistent with research findings and results in a variability that exceeds three orders of magnitude. The concept proposed in this paper argues that the complexity inherent in rockfall studies can be reduced if the stages of (i) backweathering, (ii) filling and depletion of intermediate storage on the rock face and (iii) final rockfall supply onto the talus slopes are separated as these have different response functions and controlling factors. Backweathering responds to preweathering and weathering conditions whereas the filling and depletion of intermediate storage in the rock face is mainly a function of internal and external triggers. The noise apparent in backweathering rates and rockfall supply can be reduced by integrating the relevant controlling factors in the response functions. Simple conceptual models for the three stages are developed and are linked by a time-dependent ,rockfall delivery rate', which is defined as the difference between backweathering and rockfall supply, thus reflecting the specific importance of intermediate storage in the rock face. Existing studies can be characterized according to their ,rockfall delivery ratio', a concept similar to the ,sediment delivery ratio' used in fluvial geomorphology. Their outputs can be qualified as trigger-dependent rockfall supply rates or backweathering rates dependent on (pre-)weathering conditions. It is shown that the existing quantitative backweathering and rockfall supply models implicitly follow the proposed conceptual models and can be accommodated into the uniform model. Suggestions are made for how best to incorporate non-linearities, phase transitions, path dependencies and different timescales into rockfall response functions. [source] Qualitative research to make practical sense of sustainability in primary health care projects implemented by non-governmental organizationsINTERNATIONAL JOURNAL OF HEALTH PLANNING AND MANAGEMENT, Issue 1 2004Eric G. Sarriot Abstract Sustainability continues to be a serious concern for Primary Health Care (PHC) interventions targeting the death of millions of children in developing countries each year. Our work with over 30 Non-Governmental Organizations (NGOs) implementing USAID's Child Survival and Health Grants Program (CSHGP)-funded projects revealed the need for a study to develop a framework for sustainability assessment in these projects. We surveyed NGO informants and project managers through semi-structured interviews and questionnaires. This paper summarizes our study findings. The NGOs share key values about sustainability, but are skeptical about approaches perceived as disconnected from field reality. In their experience, sustainable achievements occur through the interaction of capable local stakeholders and communities. This depends strongly on enabling conditions, which NGO projects should advance. Sustainability assessment is multidimensional, value-based and embeds health within a larger sustainable development perspective. It reduces, but does not eliminate, the unpredictability of long-term outcomes. It should start with the consideration of the ,local systems' which need to develop a common purpose. Our ability to address the complexity inherent to sustainability thinking rests with the validity of the models used to design interventions. A participant, qualitative research approach helped us make sense of sustainability in NGO field practice. Copyright © 2004 John Wiley & Sons, Ltd. [source] Literacy as a complex activity: deconstructing the simple view of readingLITERACY, Issue 2 2008Morag Stuart Abstract The Rose Review into the teaching of early reading recommended that the conceptual framework incorporated into the National Literacy Strategy Framework for Teaching , the Searchlights model of reading and its development , should be replaced by the Simple View of Reading. In this paper, we demonstrate how these two frameworks relate to each other, and show that nothing has been lost in this transformation from Searchlights to Simple View: on the contrary, much has been gained. That nothing has been lost is demonstrated by consideration of the underlying complexity inherent in each of the two dimensions delineated in the Simple View. That much has been gained is demonstrated by the increased understanding of each dimension that follows from careful scientific investigation of each. The better we understand what is involved in each dimension, the better placed we are to unravel and understand the essential, complex and continual interactions between each dimension which underlie skilled reading. This has clear implications for further improving the early teaching of reading. [source] Nomenclature and Definitions for Emergency Department Human Immunodeficiency Virus (HIV) Testing: Report from the 2007 Conference of the National Emergency Department HIV Testing ConsortiumACADEMIC EMERGENCY MEDICINE, Issue 2 2009Michael S. Lyons MD Abstract Early diagnosis of persons infected with human immunodeficiency virus (HIV) through diagnostic testing and screening is a critical priority for individual and public health. Emergency departments (EDs) have an important role in this effort. As EDs gain experience in HIV testing, it is increasingly apparent that implementing testing is conceptually and operationally complex. A wide variety of HIV testing practice and research models have emerged, each reflecting adaptations to site-specific factors and the needs of local populations. The diversity and complexity inherent in nascent ED HIV testing practice and research are associated with the risk that findings will not be described according to a common lexicon. This article presents a comprehensive set of terms and definitions that can be used to describe ED-based HIV testing programs, developed by consensus opinion from the inaugural meeting of the National ED HIV Testing Consortium. These definitions are designed to facilitate discussion, increase comparability of future reports, and potentially accelerate wider implementation of ED HIV testing. [source] | ||||||||||||||||
