Serious games are a category of games which are designed for a specific purpose other than for pure entertainment. It is not a new concept but serious games using real data, coupled with real time modelling and combining model results with social and economic factors opens up a new paradigm for active stakeholder participation. DHI and UNEP-DHI Centre initiated a project called Aqua Republica where a virtual world is developed which allows participants to develop a river basin and visualise the consequences of their decisions. The aim of this project is to raise awareness of the interconnectivity of water and educate on integrated water resources management. Aqua Republica combines a game layer with a water allocation model, MIKE BASIN, to create an interactive, realistic virtual environment where players play the role of a catchment manager of an undeveloped river catchment. Their main objective is to develop the river catchment to be as prosperous as it can be. To achieve that, they will need to generate a good economy in the catchment to provide the funds needed for development, have a steady food supply for their population and enough energy and water for the catchment. Through these actions by the player, a meaningful play is established to engage players and to educate them about the complex relationships between developmental actions in a river basin and the natural environment as well as their consequences. The game layer also consists of a reward system to encourage learning. People can play and replay the game, get rewarded from performing the right principles and penalised from failures in the game. This abstract will explain the concept of the game and how it has been used in a stakeholder participation environment.

Existing distributed hydrologic models are complex and computationally demanding for using as a rapid-forecasting policy-decision tool, or even as a class-room educational tool. In addition, platform dependence, specific input/output data structures and non-dynamic data-interaction with pluggable software components inside the existing proprietary frameworks make these models restrictive only to the specialized user groups. RWater is a web-based hydrologic analysis and modeling framework that utilizes the commonly used R software within the HUBzero cyber infrastructure of Purdue University. RWater is designed as an integrated framework for distributed hydrologic simulation, along with subsequent parameter optimization and visualization schemes. RWater provides platform independent web-based interface, flexible data integration capacity, grid-based simulations, and user-extensibility. RWater uses RStudio to simulate hydrologic processes on raster based data obtained through conventional GIS pre-processing. The program integrates Shuffled Complex Evolution (SCE) algorithm for parameter optimization. Moreover, RWater enables users to produce different descriptive statistics and visualization of the outputs at different temporal resolutions. The applicability of RWater will be demonstrated by application on two watersheds in Indiana for multiple rainfall events.

A study of Muthalapozhy fishing harbour, located in south India, was conducted for simulating shoreline changes using LITPACK modelling tool. The analysis shows that the estimated advancement in shoreline is of the order of 45 m/year initially, which gradually reduces to 25 m/year. It was also found that the coastline advances more during the south-west monsoon (i.e. June to September) season. Simulation of breakwaters shows that the length of the breakwater should be increased by 200 m for south breakwater and 70 m for north breakwater to keep the channel operational without dredging till 2016. The results of the simulated shoreline will help the port managers for maintaining the channel round the year.

Distributed energy and water balance models require time-series surfaces of the meteorological variables involved in hydrological processes. Most of the hydrological GIS-based models apply simple interpolation techniques to extrapolate the point scale values registered at weather stations at a watershed scale. In mountainous areas, where the monitoring network ineffectively covers the complex terrain heterogeneity, simple geostatistical methods for spatial interpolation are not always representative enough, and algorithms that explicitly or implicitly account for the features creating strong local gradients in the meteorological variables must be applied. Originally developed as a meteorological pre-processing tool for a complete hydrological model (WiMMed), MeteoMap has become an independent software. The individual interpolation algorithms used to approximate the spatial distribution of each meteorological variable were carefully selected taking into account both, the specific variable being mapped, and the common lack of input data from Mediterranean mountainous areas. They include corrections with height for both rainfall and temperature (Herrero et al., 2007), and topographic corrections for solar radiation (Aguilar et al., 2010). MeteoMap is a GIS-based freeware upon registration. Input data include weather station records and topographic data and the output consists of tables and maps of the meteorological variables at hourly, daily, predefined rainfall event duration or annual scales. It offers its own pre and post-processing tools, including video outlook, map printing and the possibility of exporting the maps to images or ASCII ArcGIS formats. This study presents the friendly user interface of the software and shows some case studies with applications to hydrological modeling.

Este estudo analisa os instrumentos legais e o sistema de gestão dos recursos hídricos no Estado do Amazonas e sua relação com a Lei n° 9.443, de 8 de janeiro de 1997, destacando as diferentes variáveis existentes na grande bacia hidrográfica do Amazonas que são determinantes na elaboração do marco legal no estado do Amazonas. Considerou-se, também, que a especificidade de isolamento e distanciamento existente em comparação com outros estados não pode servir de parâmetro para utilização de modelos já elaborados. O trabalho apresenta a política nacional de recursos hídricos, descreve o estágio atual da gestão de recursos hídricos nos estados do Rio de Janeiro e do Amazonas. Em seguida, analisa criticamente a lei estadual que estabeleceu a política estadual de recursos hídricos do Amazonas, e avalia comparativamente as entidades e instrumentos dos dois estados. Os métodos empregados incluem uma pesquisa bibliográfica e documental de forma a descrever e fornecer o material de aprofundamento do estudo da gestão de recursos hídricos do estado do Amazonas. A pesquisa de campo foi realizada para aprofundamento da análise crítica. Como resultados, destacam-se a necessidade da alteração da legislação atual e reestruturação administrativa dos órgãos ambientais.

Cultura organizacional e gestão de recursos humanos (GRH) são componentes fundamentais para a estratégia corporativa raramente estudada no contexto das pequenas e médias empresas (PME) no setor de serviços profissionais, um ambiente no qual o capital humano das empresas companhias é particularmente importante. Um estudo de caso de uma empresa de gestão de investimentos inglesa foi realizado. A PME quase triplicou o seu quadro de funcionários, de menos de 50 a mais de 140, nos últimos seis anos. Cultura e GRH foram pesquisadas tanto historicamente quanto no momento atual por meio de uma combinação de entrevistas individuais, observação direta durante as visitas ao local e análise documental. Foi verificado que a G RH (junto com um número de outras estruturas e processos internos) tornou-se mais formal, apesar do fato de que a empresa começou com políticas de RH relativamente desenvolvidas, em comparação com outras pequenas empresas. Uma possível explicação para esta estruturação das práticas de RH é que empresas do setor de serviços profissionais tendem a dar uma importância especial à qualidade da sua força de trabalho. Esta relativa estabilidade cultural pode ser explicada pelo fato da cultura ser forte e é mantida tanto inconscientemente quanto conscientemente, por meio de mecanismos como o planejamento de pessoal, recrutamento e remuneração. As conclusões, por conseguinte, demonstram que as atitudes e percepções nem sempre mudam tão rápido quanto sistemas organizacionais, e que a relação entre cultura e gestão de recursos humanos pode ser complexa; a formalização da GRH pode reforçar a mudança cultural em certos aspectos, ao mesmo tempo abrandá-lo em outros.

This paper considers challenges of Human Resource Management (HRM) in Open Innovation processes. It examines which strategies managers used to overcome these problems in the case of the Brazilian Oil and Gas company Petrobras. By conducting an inductive case study it develops a contextual model based on the use of grounded theory. It argues that the most important categories were to overcome problems of (a) the interpersonal relationship, (b) power shifting inside the organization, and (c) making people more valuable to the organization and shows how managers tackled these challenges. It contributes with a deep analysis of HRM challenges in Open Innovation that is important for a better understanding of management problems that can come along with Open Innovation processes.

The reality of water resources management in semiarid regions, such as the Seridó region, has been shaped by a complex chain involving social-cultural, political, economic and environmental aspects, covering different spheres of activity - from local to federal. Because water is a scarce element, the most rational way pointed out by our recent history has been to move towards an increasing emphasis on the need for a truly rational, integrated, sustainable and participatory water resources management, supported by legislation and by a network of institutions that could materialize it. In this sense, despite all the advances in the formulation of public policies in water resources, which ones have indeed lead to significant changes that have occurred or are underway in semiarid regions such as Seridó? What factors may be preventing the realization of the desires rationality embedded in the framers of water policies intents? How to properly manage water resources if the current actors who promote their management and the political, human, cultural and institutional processes that intervene in this management, show strong traces of unsustainability? The research methodology adopted in this paper led to a breakdown of the traditional approach to water resource management, to integrate it into other areas of knowledge, especially to political science and public administration, catalyzed by the concept of "sustainable development". From a broad, interdisciplinary literature review, an exhaustive characterization of the river basin Seridó, a set of interviews with key people in the public administration acting in the region, a series of diagnoses and a set of propositions were made in order to correct the direction of current public policies for the region. From the point of view of public policies, it is in the deployment phase, not in its formulation, which lies a major problem of the lack of significant progress in water management. The lack of coordination between government programs are well characterized, as well as the lack of efficiency and effectiveness of their actions. The causes of this secular model are also discussed, including political factors and social relations of production, which led to a stalemate difficult, but of possible solution. It can be perceived there is a scenario of progressive deterioration of natural resources of the fragile ecosystem and a network of environmental and social consequences difficult to reverse, the result of a persistent and inertial sociopolitical culture, whose main factors reinforce itself. The work leads towards a characterization of the water resources management also from the perspective of environmental, institutional, political and human sustainability , the latter being identified, particularly as investment in the development of people as autonomous beings - not based in ideological directives of any kind - in the emancipation of the traditional figure of the poor man of the hinterland" to the "catalyst for change" responsible for their own decisions or omissions, based upon an education for free-thinking that brings each one as co-responsible epicenter of (self-) sustainable changes in their midst

Purpose The objective of this study was to analyze the major challenges and benefits of diversity management in Brazilian companies by assessing the role of human resources. Design/methodology/approach A total of 15 case studies were carried out on companies that operate in Brazil. Brazil is a country with considerable diversity and multiracial backgrounds. Findings It was found that diversity management in Brazilian companies is still an emerging issue, and the major challenges are related to discriminatory actions taken by coworkers. Among the 15 companies studied, only four had adopted a consistent set of diversity management and human resources practices. These four companies were the only companies to affirm that diversity management requires the strong support of top management and continuous organization to sustain efforts toward incorporating diversity. Originality/value Research studies on diversity management in Brazil are scarce. The findings of this study, however, can be useful to academic professionals and company directors in countries that exhibit similar characteristics to those of Brazil, or to those who are interested in learning more about Brazil. © 2011 Emerald Group Publishing Limited.

Researchers and other professionals unanimously agree that companies should become more sustainable, but this will not happen without the support of human resource management. Paradoxically, there is a lack of information on the support human resource management offers to organizational sustainability applied to real cases. Therefore, this research presents a case study on this topic that was carried out in a leading Brazilian company, which is considered as a model and has been selected as 'the best place to work in the country'. The results provide practical examples of how this family company has been working to guarantee an increasingly sustainable performance with the support of human resources, highlighting the achievements and challenges the company has faced. One of the main results indicates that companies seeking to achieve sustainability need the assistance of the human resource field in order to design a communication system which bridges the gap between practices and sustainable values. © 2012 Management Centre for Human Values.
