Introduction : people power and the Arab revolutions : towards a new conceptual framework of democracy in the Middle East

This introductory chapter analyses the various debates and discussions that have been triggered by the Arab Revolutions. It seizes a unique opportunity to reflect on these seismic events, their causes and consequences, as well as on the core issues facing the region in the future. The central arguments and the key contributions of this chapter are twofold. Firstly, to situate the Arab Revolutions within their broader contextual background, arguing that a unique set of historical events as well as local, regional and global dynamics have converged to provide the catalyst that triggered the recent revolts. Secondly, this book will attempt to situate the events within a new conceptual framework. The argument here is that the Arab Revolutions pose a very specific challenge to conventional wisdom concerning democracy and democratisation in the Middle East.

Building capacity in sexuality education : The Northern Bay College experience : Report of the first phase of the sexuality education and community support (SECS) project

The Sexuality Education and Community Support (SECS) project aims to introduce a P-12 approach to sexuality education at Northern Bay P-12 College (NBC) through a collaborative partnership process between the schools within the College and local, regional, and state health and education agencies and has set out to change current sexual health education practice in the College and assist other schools in the region to do the same. The Project’s goal is a ‘sustainable, responsive, whole school, regionally consistent, best practice sexuality education’. During this first or establishment phase of the SECS project strategies have been implemented to begin the process of building capacity in sexuality education at NBC. These strategies are aimed at developing a sustainable approach during the next three and a half years.

Migration exhibitions and the question of identity: reflections on the history of the representation of migration in Australian museums, 1986-2011

Museums and Migration explores the ways in which museum spaces - local, regional, national - have engaged with the history of migration, including internal migration, emigration and immigration.

IUCN red list of ecosystems

We begin by briefly examining the achievements of the IUCN Red List of Threatened Species, and offering it as the model and motivator for the creation of the IUCN Red List of Ecosystems (RLE). The history of the RLE concept within IUCN is briefly summarized, from the first attempt to formally establish an RLE in 1996 to the present. Major activities since 2008, when the World Conservation Congress initiated a "consultation process for the development, implementation and monitoring of a global standard for the assessment of ecosystem status, applicable at local, regional and global levels," have included: Development of a research agenda for strengthening the scientific foundations of the RLE, publication of preliminary categories and criteria for examination by the scientific and conservation community, dissemination of the effort widely by presenting it at workshops and conferences around the world, and encouraging tests of the system for a diversity of ecosystem types and in a variety of institutional settings. Between 2009 and 2012, the Red List of Ecosystems Thematic Group of the IUCN Commission on Ecosystem Management organized 18 workshops and delivered 17 conferences in 20 countries on 5 continents, directly reaching hundreds of participants. Our vision for the future includes the integration of the RLE to the other three key IUCN knowledge products (IUCN Red List of Threatened Species, World Database on Protected Areas and Key Biodiversity Areas), in an on-line, user-driven, freely-accessible information management system for performing biodiversity assessments. In addition we wish to pilot the integration of the RLE into land/water use planning and macro-economic planning. Fundamental challenges for the future include: Substantial expansion in existing institutional and technical capacity (especially in biodiversity-rich countries in the developing world), progressive assessment of the status of all terrestrial, freshwater, marine and subterranean ecosystems, and development of a map of the ecosystems of the world. Our ultimate goal is that national, regional and global RLEs are used to inform conservation and land/water use decision-making by all sectors of society. © Author(s) 2012.

Holocene record of Tuggerah Lake estuary development on the Australian east coast: sedimentary responses to sea-level fluctuations and climate variability

We investigated the Holocene palaeo-environmental record of the Tuggerah Lake barrier estuary on the south-east coast of Australia to determine the influence of local, regional and global environmental changes on estuary development. Using multi-proxy approaches, we identified significant down-core variation in sediment cores relating to sea-level rise and regional climate change. Following erosion of the antecedent land surface during the post-glacial marine transgression, sediment began to accumulate at the more seaward location at ~8500. years before present, some 1500. years prior to barrier emplacement and ~4000. years earlier than at the landward site. The delay in sediment accumulation at the landward site was a consequence of exposure to wave action prior to barrier emplacement, and due to high river flows of the mid-Holocene post-barrier emplacement. As a consequence of the mid-Holocene reduction in river flows, coupled with a moderate decline in sea-level, the lake experienced major changes in conditions at ~4000. years before present. The entrance channel connecting the lake with the ocean became periodically constricted, producing cyclic alternation between intervals of fluvial- and marine-dominated conditions. Overall, this study provides a detailed, multi-proxy investigation of the physical evolution of Tuggerah Lake with causative environmental processes that have influenced development of the estuary.

Redes sociais e empresas II

Este relatório apresenta uma análise da bibliografia brasileira e da bibliografia internacional (anglo-saxã) sobre redes e empresas com o objetivo de contribuir para o debate teórico e orientar futuras pesquisas empíricas sobre o tema no Brasil, especialmente no campo da teoria das organizações e sociologia econômica. Para tanto, analisamos a bibliografia publicada nos últimos 10 anos (1990 a 2003) que trabalham com a abordagem de redes em três campos específicos: 1) a formação de redes entre empresas e o local onde estão inseridas; 2) o papel das redes na promoção de mudanças organizacionais e inovação; 3) o desenvolvimento de relações de confiança entre empresas e seu impacto na definição de estratégias empresariais.

Modelos de gestão da inovação: um estudo de casos em empresas brasileiras do setor petroquímico

A inovação consiste em desafio premente para inúmeras organizações, de diferentes portes e missões. Dada sua relevância para as organizações públicas e privadas, de portes variados, assim como para as economias locais, regionais, nacionais e internacionais, a gestão da inovação constitui o cerne deste estudo de casos múltiplos. A gestão da inovação e seu alinhamento com a estratégia organizacional pode representar um diferencial competitivo significativo. Através de uma visão sistêmica sobre a gestão da inovação, é possível que as organizações gerem benefícios e externalidades que poderão atender a diversos atores envolvidos e públicos interessados no processo, tais como colaboradores, parceiros de negócios, fornecedores, usuários, clientes e agências do governo. A partir desta perspectiva, a estratégia de inovação é considerada uma abordagem central no que diz respeito à estratégia empresarial. Nossa intenção na realização desta pesquisa é compreender a complexidade e o valor de processos de inovação em organizações e seus efeitos enquanto consequências de estratégias deliberadas e emergentes. Esta pesquisa propõe um modelo referencial a ser utilizado pelos gestores para o mapeamento de processos de variados graus de complexidade, com vistas a prestar suporte na gestão da inovação de produtos, processos e administrativa, de forma estruturada, com especial ênfase ao modelo do funil de inovação e sua interface com tecnologias de informação, assim como em processos organizacionais e interorganizacionais, que podem contemplar parcerias externas em inovação aberta. Foram desenvolvidos três estudos de caso, os quais formam a base deste modelo referencial. Todos os casos abrangem empresas do setor petroquímico brasileiro, sendo um caso de empresa de grande porte, a Braskem S.A., e dois casos de empresas de pequeno porte, respectivamente a Hausthene Poliuretanos Ltda. e a Prorevest Revestimentos de Poliuretanos e Peças Especiais Ltda. O modelo referencial proposto busca identificar as condições necessárias – os determinantes da inovação – que possibilitam a gestão da inovação em produtos, processos e em gestão, e seus possíveis resultados.

A perda de grupos funcionais em comunidades virtuais: efeito das interações entre espécies e grupos funcionais

High levels of local, regional, and global extinctions has progressively simplified communities in terms of both species and ecosystem functioning. Theoretical models demonstrated that the degree of functional redundancy determines the rates of functional group loss in response to species extinctions. Here, we improve the theoretical predictions by incorporating in the model interactions between species and between functional groups. In this study, we tested the effect of different scenarios of interspecific interactions and effects between functional groups on the resistance to loss of community functional groups. Virtual communities have been built with different distribution patterns of species in functional groups, both with high and low evenness. A matrix A was created to represent the net effect of interspecific interactions among all species, representing nesting patterns, modularity, sensitive species, and dominant species. Moreover, a second matrix B was created to represent the interactions between functional groups, also exhibiting different patterns. The extinction probability of each species was calculated based on community species richness and by the intensity of the interspecific interactions that act upon it and group to which it belongs. In the model, successive extinctions decrease the community species richness, the degree of functional redundancy and, consequently, the number of functional groups that remain in the system. For each scenario of functional redundancy, A, and B, we ran 1000 simulations to generate an average functional extinction curve. Different model assumptions were able to generate remarkable variation on functional extinction curves. More extreme variations occurred when the matrix A and B caused a higher heterogeneity in the species extinction probability. Scenarios with sensitive species, positive or negative, showed a greater variation than the scenarios with dominant species. Nested interactions showed greater variation than scenarios where the interactions were in modules. Communities with maximal functional evenness can only be destabilized by the interactions between species and functional groups. In contrast, communities with low functional evenness can have its resistance either increased or decreased by the interactions. The concentration of positive interactions in low redundancy groups or negative interactions in high redundancy groups was able to decrease the functional extinction rates. In contrast, the concentration of negative interactions in low redundancy groups or positive interactions in high redundancy groups was able to increase the functional extinction rates. This model shows results that are relevant for species priorization in ecosystem conservation and restoration

Saberes e práticas etnomatemáticas na carcinicultura: o caso da Vila de Rego Moleiro-RN

This study addresses issues related to the mathematical knowledge and practices of the workers of carcinoculture (shrimp farming), associating such knowledge and practices to the conceptual aspects and the academic mathematical language. Our central aim was to investigate and discuss such knowledge and practices in order to contribute towards having the members of this group reflect upon their own working practices. The investigation took as reference the ethnographic research approach during observations and interviews, as well as the analysis and interpretation of the existing cultural aspects on the use of Mathematics in the shrimp farmers daily activities, thus composing the four chapters of this dissertation. Initially, the local-regional context was set in the area where the workers of the shrimp farm reside, also describing our methodological options. After that, the kind of work that was carried out is explained through a brief history of the shrimp-farming activity, including a short discussion on the environmental impacts that result as a consequence of shrimp-farming. We then discuss some theoretical and practical aspects of the Ethnomathematics while field of study and research. At that moment, we make a reflection upon the different kinds of Mathematics, especially stressing the kind of Mathematics being taught in Schools and that being put to practice by identifiable cultural groups. With that in mind, we show the investigated knowledge and practices e some possible systematizations accomplished during the study. In the end, we point out some conclusive propositions based on the implications of our study towards the development of an educational process within the local communities, considering a possible use of the results and conclusions of this study in the classroom activities

Descompassos nas políticas educacionais: a reorganização da educação rural em Jardim de Piranhas/RN

The present work has as aim to analyze the reorganization process of the rural education in Jardim de Piranhas-RN, on the context of the education policies, in particular of the period of 1999-2006, having as reference the transformations in the political, cultural and socio-economic setting in the national, regional and local level, above all from the decade of 1990. The studies carried out in diverse sources made possible to understand from the context in which they had developed the education policies, in particular, that one directed for the rural way, as well as the mediation of this with the education reorganization in the local scope. Besides these research procedures, we carry out interviews - semi-structuralized - with managers and teachers, and we analyze documents from the produced ones in national level to those local ones. From the viewpoint theoretician-methodological, we focus the national discussion that comes developing under a new ideological political configuration and, being entitled by the Field Education, understood as a policy directed to education specifities in this sector and consolidated in the Operational Guidelines for the Basic Education in the Field Schools (CNE/MEC/2002). As particularity of this object in Jardim de Piranhas-RN, we emphasize events occurred that had marked the rural education reorganization in that city, especially from the creation of the Rural Education named Center Teacher Maria Edite Batista. Studies make possible to realize that until the Center creation, the schools functioned in rather precarious infrastructure and physical conditions, that is, without electric energy and water supplying, as well as the lack of school snack and the management structure. There was not a project or specific pedagogical accompaniment for the sector. Moreover, the teachers worked predominantly with several grade classes and still they fulfilled the manager functions, caretakers, and cook- in some cases as school secretary. However, exactly with the creation of the Rural Education Center, the education municipal system did not become capable to overcome problems as of the evasion and school failure, as well as decreasing the work overload of teachers, neither to give greater consistency to the pedagogical project of the field schools in that city

Mapeamento de ambientes estruturados com extração de informações geométricas através de dados sensoriais

The objective of this thesis is proposes a method for a mobile robot to build a hybrid map of an indoor, semi-structured environment. The topological part of this map deals with spatial relationships among rooms and corridors. It is a topology-based map, where the edges of the graph are rooms or corridors, and each link between two distinct edges represents a door. The metric part of the map consists in a set of parameters. These parameters describe a geometric figure which adapts to the free space of the local environment. This figure is calculated by a set of points which sample the boundaries of the local free space. These points are obtained with range sensors and with knowledge about the robot s pose. A method based on generalized Hough transform is applied to this set of points in order to obtain the geomtric figure. The building of the hybrid map is an incremental procedure. It is accomplished while the robot explores the environment. Each room is associated with a metric local map and, consequently, with an edge of the topo-logical map. During the mapping procedure, the robot may use recent metric information of the environment to improve its global or relative pose

Recidiva de câncer labial em pacientes atendidos no hospital DR. Luiz Antônio (Natal-RN) entre 1997-2004

Introduction: Cancer of the lip is very common in tropical countries, being noticeable the squamous cell carcinoma as the main histological type. Objective: Evaluate the socialdemographic profile, habits, occupation, clinical characteristics of the cancer lesions and the aftermath of treatment of the patients treated on the Luiz Antônio Hospital (Natal-RN). Design: Retrospective cohort. Methods: We analyzed 181 medical records of patients from the Luiz Antônio Cancer Hospital (Natal-RN) in the period between 1997 and 2004. The statistic evaluation of time between the diagnosis and the relapse or the cure of the patient were done through the Kaplan-Meier method and the comparison of survivor functions were done through the Log-rank test. Later, was estimated the proportional risk model of Cox. Results: The study population were composed by 69,1% males, 95,2% unlettered, the mean age of 66,5 years, 89,0% of smokers and 64,1% had an occupation involving sun exposure. In regard to the clinical characteristics, most lesions were in the lower lip (77,9%), the size of the tumor was smaller than 2 cm (51,8%), 92,6% had localized lesions. Were verified 16,3% of local relapse and 13% of regional. Almost the totally of the cases corresponded to squamous cell carcinoma (97,2%). We observed smaller accumulated probability of not occurrence of local relapse when the base and borders were free of lesions (p=0,041), as well as a smaller probability of regional relapse when the sort of treatment was surgery, associated with other therapeutics modalities (p=0,001). The patients with advanced pathologic stage (p=0,016), treated with surgery associated with other therapeutics modalities (p=0,001) and diameter above 4cm (p=0,019) presented a bigger possibility of any kind of relapse. The multivariable analysis pointed the complex treatments (surgery plus other therapeutics modalities) as a predictor variable for occurrence of new local lesions (p=0,001) and total (p=0,046), besides the age above 70 years to the regional relapse (p=0,050). Conclusion: Cancer of the lip occur in the lower lip, in males, smokers and individuals exposed to Sun light. The relapse was frequent, even being localized and without great consequences to the patient s health. The probability of relapse is related to the size and borders of the lesion and to the histological exam, as well as to the patient s age and complexity of the treatment chosen

Caracterização e composição florística de uma comunidade savânica no Rio Grande do Norte, Brasil : subsídios para a conservação

Studies on Brazilian biodiversity are still very few and can observe the difference of knowledge between the different regions of the country. This affirmation can be verified in the investigation to identify the rare species in Brazil and the key biodiversity areas (ACBs). In that study were identified for Brasil 2.256 rare species and 752 ACBs. The Rio Grande do Norte (RN) was the only Brazilian state that has not been identified any rare species and no ACBs, possibly due to the lack of floristic studies in this state. A particular area was selected for this study: an area of ecological tension with savanna physiognomy in Rio do Fogo, RN. This savanna community is represented in RN in a fragment and immersed in restinga and caatinga and was identified and described only through of radar imagens there are no studies to date in loco . We have prepared the following questions about this community savanna: 1) The region delimited and described by through of radar images by the RADAMBRASIL, 1976, can be associated of the Cerrado, in terms of floristic ?; 2) What is the floristic composition of this area? This area includes rare species, endemic or endangered? 3) What is the geographical and phytogeographical distribution of plant species registered in this area? 4) Those plant species registered are endemic or have affinity with other areas phytoecological Brazilian? To answer these questions we performed a floristic inventory of the August 2007 to September/2009. The results are presented in two chapters (manuscripts). The first chapter, titled "The Savannah Rio Grande do Norte: floristic links with other plant formations in the Northeast and Center-West Brazil" was submitted to the Revista Brasileira de Botância. Chapter 1 discusses the phytogeographical distribution of the species, by comparing floristic studies conducted in the Cerrado, Caatinga and Restinga in the Northeast and Cerrado of the Central Brazil. The analysis of data of this study and compilation with other studies indicated that: i) the record of 94 plant species; ii) of total species, about 64% are associated with the Cerrado, the second specialized bibliography, and about 78% as the List of Species of Flora of Brazil. However, about 73% of total species (94) are also distributed in the Caatinga, the Atlantic forest 64%, the Amazon forest 64%, the Pantanal 15% and the Pampa 12%. Floristically the data show that the community studied is influenced by other floras, has a structure where grasses dominate and also because of his appearance the same savanna then be classified as a Savana gramíneo-lenhosa do tabuleiro . Chapter 2, titled "Considerations on the flora of a savanna community in Rio Grande do Norte, northeastern Brazil: Subsidy key area for conservation" was submitted to the Revista Natureza e Conservação. This has the objective of improve the knowledge of flora of Rio Grande do Norte and to identify possible rare species and consequently increase the key areas of biodiversity in Brazil. The data indicated that: i) of 94 species registered in the study area, 40 were new records for the Rio Grande do Norte state; ii) These citations to unpublished state, Stylosanthes montevidensis Vogel (Fabaceae) and Aristida laevis (Nees) Kunth (Poaceae) are indicated for the first time to the Northeast of Brazil; iii) are registered in the area 24 species endemic to Brazil and 63 non-endemic; iv) Aspilia procumbens Baker (Asteraceae) registered in the area is considered a restricted species and micro endemic Rio Grande do Norte, ie rare species; v) Aspilia procumbens is also cited in the category of critically endangered species and Stilpnopappus cearensis Hubber (Asteraceae) a species vulnerable to extinction. This study shows a new area phytoecological in Rio Grande do Norte and indicates the area's potential to contribute with the sites of global significance for biodiversity conservation, either locally, regionally and nationally. This will certainly contribute to respond some targets set by the Global Strategy for Plant Conservation and the Convention on Biological Diversity such as the inventory of vegetal diversity in a region with little collection, which will provide data that contributes to questions and themes related to biodiversity.

Análise da evolução costeira do litoral setentrional do estado do rio grande do norte, região sob influência da indústria petrolífera

The northern coast of Rio Grande do Norte State is characterized by strong changes in coastal morphology, caused by various geological and climatic factors. In this region are installed the main socio-economic activities of the State, highlighting the oil industry, which exerts much of its activities in the coastal area studied. Erosion is a constant problem in this region because it affects the entire local populace to the destruction of houses and trade, rendering tourism, affecting the livelihood activities and industrial activities. The greatest risk is related to environmental damage that can be caused by the oil spill in this region. To understand what determines the changes in coastal morphology this Doctoral Thesis is proposed to identify the factors at local, regional and even global corroborate coastal dynamics to this coast in question. For this study, used several different products and tools for interpreting the conditions of the erosive effect that dominates the whole northern coast of the State, in an attempt to quantify and describe the causes and effects that affect the entire coastal zone monitored. The development of activities is built into the projects Rede 05 PETROMAR (CTPETRO-FINEP/PETROBRAS/CNPq), PETRORISCO, HIDROSEMA, PETROMAR e Rede 05/04 POTMAR (FNDCT/CTPETROFINEP/ CNPq), in the activities of multidisciplinary and inter-features in issues involving environmental monitoring and oil activity

Monitoramento da qualidade das ásguas de chuvas conforme a atuação dos sistemas sinóticos na cidade de Natal/RN

Acid rain is a major assault on the environment, a consequence of burning fossil fuels and industrial pollutants the basis of sulfur dioxide released into the atmosphere. The objective of this research was to monitor and analyze changes in water quality of rain in the city of Natal, seeking to investigate the influence of quality on a local, regional and global, in addition to possible effects of this quality in the local landscape. Data collection was performed from December 2005 to December 2007. We used techniques of nefanálise in identifying systems sinóticos, field research in the search for possible effects of acid rain on the landscape, and collect and analyze data of precipitation and its degree of acidity. Used descriptive statistics (standard deviation and coefficient of variation) used to monitor the behavior of chemical precipitation, and monitoring of errors in measurements of pH, level of confidence, Normalized distribution of Gauss, confidence intervals, analysis of variance ANOVA were also used. Main results presented as a variation of pH between 5,021 and 6,836, with an average standard deviation of 5,958 and 0,402, showing that the average may represent the sample. Thus, we can infer that, according to the CONAMA Resolution 357 (the index for fresh water acidity should be between 6.0 and 9.0), the precipitation of Natal / RN is slightly acidic. It appears that the intertropical convergence zone figures showed the most acidic among the systems analyzed sinóticos, taking its average value of pH of 5,617, which means an acid value now, with a standard deviation of 0,235 and the coefficient of variation of 4,183% which shows that the average may represent the sample. Already in field research and found several places that suffer strongly the action of acid rain. However, the results are original and need further investigation, including the use of new methodologies
