An agile transformation process presents challenges to organizations around the world. Research on agile success factors is not conclusive and there is still need for guidelines to help in the transformation process considering the organizational context. This research proposes a survey among practitioners to identify the difficulty to implement success factors in organizations to create a fertile environment for agile transformation. We conducted a survey with 457 practitioners resulting in 328 valid responses. The findings show that the success factors implementation difficulty rankings generated for all practitioners and for expert practitioners have a high correlation. According to expert practitioners, measurement model and changes in mindset of project managers are the hardest success factors to implement while incentives and motivation to adopt agile methods and management buy-in are the easiest to implement. The contribution of this research is a ranking organizations can use as a reference for their agile transformation processes. © Springer International Publishing AG 2017.

Competitive Intelligence is a process which involves retrieving, analyzing and packaging information to offer a final product that responds to the intelligence needs of a particular decision maker or community of decision makers. Competitive Intelligence Professionals transform raw data and information into intelligence by collecting and organizing information resources. Mining companies have a Mineral Exploration Department in charge of a comprehensive geological research program all over the world focused on the discovery of mineral deposits. This paper presents a proposal for extracting the information and the data sources commonly used by competitive intelligence professionals responsible for analyzing the mining market. Specifically, this paper intends to answer the following research question: What is the information used to analyze external environments, from the mining companies perspective? To achieve this goal and taking the social-Technical design into account, we performed a focus group with experienced professionals from a mining company. As a result of this work, we present: 1) a list of generic data sources; 2) a categorized list of common information used to analyze the external environment; and 3) the main difficulties reported by professionals of this area.


Due to the worldwide phenomenon of population aging, designers face a new challenge regarding collective housing. An important set of users with special needs requires not only adapted housing in physical terms, but also adequate environment in social and operational terms. This paper reflects observations and registration of case studies to highlight the various strategies that underlie senior housing projects. Throughout the article, three words or descriptors are observed, which can become real project operators, to wit, satellite habitat, undifferentiated matrix, and appropriation space.

A successful piece of applied research will not only influence the related problem perception within the scientific community, but also lead to much better understanding of a complex challenge, including the delivery of solutions. Ideally it may contribute significantly to reducing possible risk situations for people and/or the natural environment. In short, a successful study will have a broader impact beyond the sphere of science. Planning, timing, funding, networking, communication, and interdisciplinarity are identified as key aspects for a successful project and are being examined in their scope and boundary conditions, while not neglecting the particular role of local and regional people and authorities.Defining what makes a successful environmental geochemical study is clearly based upon experience and evidence found, and not upon any particular theoretical concept. Here, experience is drawn from the outcome of many projects and specifically first-hand from the complex ARSENEX project in Minas Gerais, Brazil. Against the backdrop of both perceived and real arsenic contamination of environmental compartments, including local people, all subsequent project steps and proposals were set up using a three-prong approach that sought to a) understand the processes, b) educate and inform the public and all other stakeholders and c) remediate the situation. © 2015 Elsevier Ltd.


The scope of this study is to identify the factors that influence the consumer's decision when buying medicine. Prior to the Generics Act (Lei dos Genéricos), consumers had at their disposal two product purchase options in the private market, namely buying a reference drug and a similar one. Generic drugs are part of a public policy which was intended to broaden access to medication by the general population at more accessible costs, while maintaining the same quality as the reference drug, as ensured by bioequivalence tests from the national health surveillance agency ANVISA. Nevertheless, a question arises as to whether the potential consumer knows the difference between generic, similar and reference drugs, especially when taking into account the decision at the moment of purchase. In order to fulfill the proposed objective, a survey was conducted with 403 residents in Belo Horizonte, Brazil. The data gathered was tabulated and analyzed using factor analysis and crosstab. The results made it possible to infer that there is a strong predisposition among consumers to accept the suggestions of the pharmacists and/or salesman, and a significant portion of the population is confused at the moment of purchase.

The Role-based Access Control (RBAC) model provides a safe and efficient way to manage access to information of an organization, while reducing the complexity and cost of security administration in large networked applications. However, Web Engineering frameworks that treat access control models as first-class citizens are still lacking so far. In this paper, we integrate the RBAC model in the design method of Semantic Web applications. More specifically, this work presents an extension of the SHDM method (Semantic Hypermedia Design Method), where these access control models were included and seamlessly integrated with the other models of this method. The proposed model allows the specification of semantic access control policies. SHDM is a model-driven approach to design Web applications for the Semantic Web. This extension was implemented in the Synth environment, which is an application development environment that supports designs using SHDM. © 2012 Springer-Verlag.

In this work, a novel approach to fatigue life prediction under step-stress conditions is introduced, where the cumulative distribution function for the failure of components was implemented by means of a neural network. The model was fit to experimental data on the fatigue life of steel under step-stress conditions. For comparison, a standard approach based on the lognormal distribution function was also implemented and fit to the same experimental data. Both models were optimized by evolutionary computation, using a maximum likelihood estimator. The Kolmogorov-Smirnov test was applied to compare the results of the new approach to those obtained with the lognormal distribution function. © 2010 Elsevier Inc. All rights reserved.

This paper introduces a numerical model to estimate fatigue life under step-stress conditions, using the Weibull and lognormal distributions. The maximum likelihood method was used to estimate the free parameters of the distributions. The model was fitted to an experimental data on fatigue life in the specimens of steel SAE 8620, by using evolutionary computation to optimize the likelihood function. Results are reported on the values of the parameters and their confidence interval. Also, a validation of the model is discussed using analysis of residuals. © 2013 Wiley Publishing Ltd.

Process modeling is an expensive task that needs to encompass requirements of different stakeholders, assure compliance with different standards, and enable the flexible adaptivity to newly emerging requirements in today's dynamic global market. Identifying reusability of process models is a promising direction towards reducing the costs of process modeling. Recent research has offered several solutions. Such solutions promote effective and formally sound methods for variability modeling and configuration management. However, ensuring behavioral validity of reused process models with respect to the original process models (often referred to as reference process models) is still an open research challenge. To address this challenge, in this paper, we propose the notion of business process families by building upon the well-known software engineering discipline-software product line engineering. Business process families comprise (i) a variability modeling perspective, (ii) a process model template (or reference model), and (iii) mappings between (i) and (ii). For business process families, we propose a correct validation algorithm ensuring that each member of a business process family adheres to the core intended behavior that is specified in the process model template. The proposed validation approach is based on the use of Description Logics, variability is represented by using the well-known Feature Models and behavior of process models is considered in terms of control flow patterns. The paper also reports on the experience gained in two external trial cases and results obtained by measuring the tractability of the implementation of the proposed validation approach. © 2013 Elsevier Ltd.

Within the main strategies of the Modern Movement, a thing that insistently appears is the so-called 'planning in section': housing rooms enclosed in vertically-displaced story buildings. Resorting to Wells Coates' words, the traditional flat apartment has evolved into other models, with distinct single-story not flat solutions. Such strategy brought multiple advantages, from higher space efficiency, by reducing the collective flow of people, to the minimization of noise level transmission from between adjacent rooms. The most classic model is likely that of Unité d'Habitation de Marseille (1947), by Le Corbusier, but before and after that, several models were built, a lot of them in America and Latin America, boasting geometries even more intricate and complex. It is not hard to find models that, when observing their section, denote high complexity. Inside, the rooms often appear displaced in multiple levels, with variations of one height, one-and-a-half height, double height ceiling, of several duplex, triplex floors, etc. Sometimes, words lack to name the large number of types of apartments that may be hidden behind such homogeneous image. This seems to have a certain parallelism to what is happening today. If, throughout the Modern Movement, the façades were built as perfect prisms, now it seems that there is some insistency in getting away from this concept by exposing diversity. The current façades often like to show the abundance of 'random compositions' or 'enriching heterogeneity' in a system in which the internal complexity plays an important role as indicator of plurality. Multiplicity and complexity proudly boast themselves and are also composition resources. Copyright © 2014 IAHS.
