The scenario planning literature is focused on corporate level interventions. There is a general consensus on the method, but there is little debate about the stages involved in building and using the scenarios. This article presents a case study of a scenario planning intervention, which was conducted at a business unit of the British division of one of the largest beauty and cosmetic products multinationals. The method adopted in this case study has some fundamental differences to the existing models used at corporate level. This research is based on the principles of autoethnography, since its purpose is to present self-critical reflections, enhanced by reflective and reflexive conversations on a scenario planning method used at business unit level. The critical reflections concern a series of critical incidents which distinguish this method from existing intuitive logic scenario planning models which are used at corporate level planning. Ultimately this article contributes to the scenario planning method literature by providing insights into its practice at business unit level. © 2012 Elsevier Ltd.

Evaluations of semantic search systems are generally small scale and ad hoc due to the lack of appropriate resources such as test collections, agreed performance criteria and independent judgements of performance. By analysing our work in building and evaluating semantic tools over the last five years, we conclude that the growth of the semantic web led to an improvement in the available resources and the consequent robustness of performance assessments. We propose two directions for continuing evaluation work: the development of extensible evaluation benchmarks and the use of logging parameters for evaluating individual components of search systems.

There have been multifarious approaches in building expert knowledge in medical or engineering field through expert system, case-based reasoning, model-based reasoning and also a large-scale knowledge-based system. The intriguing factors with these approaches are mainly the choices of reasoning mechanism, ontology, knowledge representation, elicitation and modeling. In our study, we argue that the knowledge construction through hypermedia-based community channel is an effective approach in constructing expert’s knowledge. We define that the knowledge can be represented as in the simplest form such as stories to the most complex ones such as on-the-job type of experiences. The current approaches of encoding experiences require expert’s knowledge to be acquired and represented in rules, cases or causal model. We differentiate the two types of knowledge which are the content knowledge and socially-derivable knowledge. The latter is described as knowledge that is earned through social interaction. Intelligent Conversational Channel is the system that supports the building and sharing on this type of knowledge.

The advances in building learning technology now have to emphasize on the aspect of the individual learning besides the popular focus on the technology per se. Unlike the common research where a great deal has been on finding ways to build, manage, classify, categorize and search knowledge on the server, there is an interest in our work to look at the knowledge development at the individual’s learning. We build the technology that resides behind the knowledge sharing platform where learning and sharing activities of an individual take place. The system that we built, KFTGA (Knowledge Flow Tracer and Growth Analyzer), demonstrates the capability of identifying the topics and subjects that an individual is engaged with during the knowledge sharing session and measuring the knowledge growth of the individual learning on a specific subject on a given time space.

This paper contributes a new methodology called Waste And Source-matter ANalyses (WASAN) which supports a group in building agreeable actions for safely minimising avoidable waste. WASAN integrates influences from the Operational Research (OR) methodologies/philosophies of Problem Structuring Methods, Systems Thinking, simulation modelling and sensitivity analysis as well as industry approaches of Waste Management Hierarchy, Hazard Operability (HAZOP) Studies and As Low As Reasonably Practicable (ALARP). The paper shows how these influences are compiled into facilitative structures that support managers in developing recommendations on how to reduce avoidable waste production. WASAN is being designed as Health and Safety Executive Guidance on what constitutes good decision making practice for the companies that manage nuclear sites. In this paper we report and reflect on its use in two soft OR/problem structuring workshops conducted on radioactive waste in the nuclear industry. Crown Copyright © 2010.

Serious inequities in our K-12 public education system, particularly in regard to the quality of education in predominately Black inner-city schools, are well-documented in the literature (Freeman, 1998; Ross, 1998). Moreover, there is general agreement that the most effective means of ameliorating that situation is through well-thought-out after-school programs and partnership initiatives (Beck, 1993; Gardner et al., 2001). ^ The purpose of this qualitative study was to examine the programmatic interventions of a youth enrichment program for inner-city Black youth currently in place at the Overtown Youth Center (OYC) in Miami, Florida, in order to: (a) discern those factors that support its claim that it is making a difference in students’ lives, (b) explore how any such factors are implemented, and (c) determine whether its interventions have served to equalize the playing field for these youth. ^ Two primary methods of data collection were used for this study. The first was participant observation conducted over the course of two years through a partnership initiative established and led by this author. The second was through in-depth interviews of the Center’s founder, staff, and students. Secondary methods used were the recording of informal conversations and the analysis of written documents. ^ Analysis of the data yielded four features of the Center that are indispensible to the students’ growth. The center provides the youth with (a) physical and psychological safety, (b) supportive relationships, (c) exposure to cultural and educational opportunities, and (d) assistance in building self-esteem. ^ The most significant finding of the study was that OYC has been successful at making a difference in students’ lives and at increasing their aspirations to attend college. By addressing the full spectrum of their needs, the Center has given them many of the necessary tools with which to compete and thereby helped equalize their opportunities to succeed in school and in life. ^ The study also noted a number of challenges for the Center to examine. The main issues that need to be addressed more seriously are staff turnover, staff indifference, nepotism, inconsistent student attendance, and insufficient focus on racial issues and African-American-centered education. Meeting those challenges would engender even greater positive outcomes.^

The need for efficient, sustainable, and planned utilization of resources is ever more critical. In the U.S. alone, buildings consume 34.8 Quadrillion (1015) BTU of energy annually at a cost of $1.4 Trillion. Of this energy 58% is utilized for heating and air conditioning. ^ Several building energy analysis tools have been developed to assess energy demands and lifecycle energy costs in buildings. Such analyses are also essential for an efficient HVAC design that overcomes the pitfalls of an under/over-designed system. DOE-2 is among the most widely known full building energy analysis models. It also constitutes the simulation engine of other prominent software such as eQUEST, EnergyPro, PowerDOE. Therefore, it is essential that DOE-2 energy simulations be characterized by high accuracy. ^ Infiltration is an uncontrolled process through which outside air leaks into a building. Studies have estimated infiltration to account for up to 50% of a building's energy demand. This, considered alongside the annual cost of buildings energy consumption, reveals the costs of air infiltration. It also stresses the need that prominent building energy simulation engines accurately account for its impact. ^ In this research the relative accuracy of current air infiltration calculation methods is evaluated against an intricate Multiphysics Hygrothermal CFD building envelope analysis. The full-scale CFD analysis is based on a meticulous representation of cracking in building envelopes and on real-life conditions. The research found that even the most advanced current infiltration methods, including in DOE-2, are at up to 96.13% relative error versus CFD analysis. ^ An Enhanced Model for Combined Heat and Air Infiltration Simulation was developed. The model resulted in 91.6% improvement in relative accuracy over current models. It reduces error versus CFD analysis to less than 4.5% while requiring less than 1% of the time required for such a complex hygrothermal analysis. The algorithm used in our model was demonstrated to be easy to integrate into DOE-2 and other engines as a standalone method for evaluating infiltration heat loads. This will vastly increase the accuracy of such simulation engines while maintaining their speed and ease of use characteristics that make them very widely used in building design.^

This work presents a proposal to build a Mathematics Teaching Laboratory (MTL) whose main theme is the study, construction and use of instruments for navigation and location of mathematical content in an interdisciplinary way approach, and develop a notebook of activities focused on navigational instruments. For this it was necessary a literature review to understand the different conceptions of MTL and its pedagogical implications. The methodology used was literature research, construction and handling of instruments, and pedagogical experimentation. Lorenzato (2006) highlights the importance of an environment and suitable for a professional who can do a good job instruments. The implementation of an LEM can find some obstacles. The lack of support from other teachers or the management, the lack of a suitable place to store the materials produced, the lack of time in the workload of the teacher to prepare the lab activity, etc. Even in unfavorable or adverse conditions, according Lorenzato (2006), its implementation will benefit teachers and students. The lack of teacher training in their initial and continuing education, to use materials, and the lack of manuals with lab activities are also mentioned as factors that keep teachers from MTL. With propóposito assist the teacher of elementary or middle school in building a theme MTL prepared and we are providing a notebook of activities that provides a didactic sequence involving History and Mathematics. The book consists of four accompanied by suggestions for teachers activities, however the teacher has full autonomy to adapt the activities to the reality of your school. Among the instruments of navigation presented in this study chose to build the quadrant due to its simplicity, low cost of material and great teaching potential that this instrument has. But a theme lab is always being built and rebuilt as it is a research environment

The purpose of this study is to search the school group Barão de Mipibú/RN, which is located in a city called São José de Mipibú. The aim of this work is to discuss about the use of education as a tool for the formation of the republican imaginary society norte-riograndense. We defined a period from 1909 through 1920. The choice of this work is about how this could be important to the Brazilian History of Education and local, as well as for Cultural History and extends to studies of everyday school life and history of school disciplines. Their achievement was through bibliography search and document analysis. The first was through a review of bibliography on the national and local historiography about the School Groups and productions of the Brazilian Republic. The last one, through the following sources, namely, just the same building of the school group Barão de Mipibú, furniture inventories, class daily, terms of visits of Education Directors and reports of the Directors, book Our History by Rocha Pombo, Educational Legislation, Legislative Congress posts, the decree of creation of School Groups, in particular Barão de Mipibú and the Group Model Augusto Severo, as well as the internal statute and finally, interviews with Alumni of the 50s. The study is inserted in the history of education and as the theoretical to assist in the analysis of sources on the imagination of the study, we looked for support in Jacques Le Goff (1994), Bronislaw Bazcko (1985), Cornelius Castoriadis (1982). At the end of this work it was possible to get the understanding that the Republican government found in the educational Field, one way to spread their ideals and collaboration in building the social Imaginary of the republic, which was constituted in the early twentieth century.

Significant advances have emerged in research related to the topic of Classifier Committees. The models that receive the most attention in the literature are those of the static nature, also known as ensembles. The algorithms that are part of this class, we highlight the methods that using techniques of resampling of the training data: Bagging, Boosting and Multiboosting. The choice of the architecture and base components to be recruited is not a trivial task and has motivated new proposals in an attempt to build such models automatically, and many of them are based on optimization methods. Many of these contributions have not shown satisfactory results when applied to more complex problems with different nature. In contrast, the thesis presented here, proposes three new hybrid approaches for automatic construction for ensembles: Increment of Diversity, Adaptive-fitness Function and Meta-learning for the development of systems for automatic configuration of parameters for models of ensemble. In the first one approach, we propose a solution that combines different diversity techniques in a single conceptual framework, in attempt to achieve higher levels of diversity in ensembles, and with it, the better the performance of such systems. In the second one approach, using a genetic algorithm for automatic design of ensembles. The contribution is to combine the techniques of filter and wrapper adaptively to evolve a better distribution of the feature space to be presented for the components of ensemble. Finally, the last one approach, which proposes new techniques for recommendation of architecture and based components on ensemble, by techniques of traditional meta-learning and multi-label meta-learning. In general, the results are encouraging and corroborate with the thesis that hybrid tools are a powerful solution in building effective ensembles for pattern classification problems.

The National Policy on Mental Health is characterized as a territorial - political community , and it has the Psychoso cial Care Strategy (Eaps) as guideline for the proposal and the development of their actions. In its design, CAPS is idealized to be a strategic equipment within the Psychoso cial Care Network/RAPS. Matricial support and at tention to the crisis constitute strategic areas of action of CAPS in its replacement mission , and as it is g uided by the scope of deinstitutionalization, those are essential to the success of these services. We argue that sustain crises in existential territories of life is a condition for the effectiveness of psychosocial care and, ultimately, to the sustainability of its Reform. In this direction, the matricial support tool reveals a territorial supporter, intercessory and powerful in building a psychosocial care to the crisis. Recognized as one of the major challenges by the Brazilian Ministry of Health, forward these fronts materializes for workers in their mi cropolitical crafts. Our research arises as an investment toward empower them , and aimed to understand the operationalization of attention to the crisis and matricial support in a CAPS II, in the view of its workers . Besides, it aims to examine such practi ces forward the principles and purposes of Psychosocial Care Strategy. Inspired by the research - intervention and by the political and social ideas of Institutiona l Analysis, we offer a space for reflection and exchange, by implicational interviews , enablin g workers to launch them in analysis of practices in the EAPs view. We have done a documentary consulting CAPS Technical Project, and a return stage to the institution, by organizing workshop and conversation groups with CAPS workers. The results have show n that there are institutional logics in competition on that service. When operating the logic risk, some difficulties in sustaining most intense crisis situations were identified, the psychiatric hospital internment is used as a facility, particularly in view of some cases, in which the aggressiveness of the person in crises becomes aggressive, and when the brackets SAMU, the CAPS III and Comprehensive Care Beds do not respond satisfactorily to their users requests. Order weaknesses were indicated in this thesis as macropolitical and micropolitical interfering in network support. The matricial actions were identified as a powerful intercessor resource in crisis care appeared weakened, and indicates little porosity in the relationship between the Service and the territory where it takes place. Noticed by the logic of home care, without operate primarily as a knowledge exchange device, we saw capture points in the logic of assistance with ambulatoriza tion production of CAPS, welfare practices and "ext empore " . T he E APs , although it emerge s as a guiding, it is not seen to workers as effective practice. On the one hand, the results signaled that the attention to the crisis and the matricial actions are developed without tenacious connection with the purposes of EA Ps, on the other hand, successful cases were indicated with the main leads to conducting wire of intersectoral actions to the powerful bonds and to the participation of user in their care process es , indicating insurgent forces tha t intend by traditional lo gic .
