AbstractThis study was part of the Long Term Ecological Project (PELD) conducted in the São Francisco de Paula National Forest, RS where Mixed Ombrophilous Forest is predominant. The aim was to identify distribution of arboreous species depending on different soil conditions occurring in the low, medium and upper slopes of the studied area. 180 sample units of 100 m2 distributed along the topographical gradient were installed, with identification of the totality of arboreous species with 3 cm ≤ CBH < 30 cm and height exceeding 1.30 meters. In addition, thirteen environmental variables were collected in each sub-unit. The Canonical Correspondence Analysis model (CCA) indicated that only the slope, the topographic position, the stoniness and the soil color (up to 50 cm in depth) were the variables that best distinguished the sample groups of the slope environments. Out of the 53 species included in the model, ten species showed best correlations with the typical environments of upper slopes and 12 species were most characteristics of the lower positions, while the remaining resulted well adapted to different hillside topographic conditions. Environmental preferences of the species could be considered in silvicultural and recuperation programs applied to hillside environments of the region.Keywords:  Araucarian Forest; species distribution pattern, edaphic characteristics; canonical correspondence analysis. ResumoOcupação de espécies arbóreas em um gradiente topográfico na Floresta Ombrófila Mista no Rio Grande do Sul. O presente estudo foi parte do Projeto Ecológico de Longa Duração (PELD), realizado na Floresta Nacional de São Francisco de Paula, RS, onde predomina a Floresta Ombrófila Mista. O objetivo foi identificar relações de distribuição das espécies arbóreas em diferentes condições edáficas que ocorrem em posições inferiores, médias e superiores em encostas na área de estudo. Foram instaladas 180 subunidades amostrais de 100 m2 distribuídas ao longo dessas encostas, identificados todos os indivíduos arbóreos com 3 cm ≤ CAP < 30 cm e altura superior a 1,30 metros, além de13 variáveis ambientais inventariadas em cada subunidade. O modelo de Análise de Correspondência Canônica (ACC) indicou que a variação na declividade, na posição topográfica, na pedregosidade e na cor dos solos (na profundidade de até 50 cm) foram as variáveis que melhor distinguiram os grupos de parcelas que caracterizaram os ambientes das encostas. Das 53 espécies inseridas no modelo, dez espécies demonstraram maiores correlações com os ambientes típicos das encostas superiores e 12 espécies foram mais características das posições inferiores, enquanto que as demais apresentaram ampla adaptação às diferentes posições das encostas. As preferências ambientais das espécies poderiam ser consideradas em programas silviculturais e de recuperação nos ambientes de encostas na região.Palavras-chave:  Floresta com Araucária; padrão de distribuição de espécies; características edáficas; análise de correspondência canônica.

Abstract A survey of Odonata was carried out in the National Forest FLONA - SFP, Northeastern region of the Rio Grande do Sul state, Brazil. This conservation unit is mainly covered by Mixed Ombrophilous Forest (MOF), a subtype of Atlantic Forest biome, being also areas covered in planted Pinus, planted Araucaria and open fields. Our sampling efforts were conducted in thirty aquatic environments inside this reserve during the period between January 2014 and November 2014. The sampling sites were selected randomly, comprehending lakes, bogs, small streams and river sections, all inserted in the four vegetation types occurring in the reserve. Fortysix species of Odonata were collected and grouped into 23 genera and seven families. The dominant families were Coenagrionidae (32%), Libellulidae (32%), Aeshnidae (12%), and, Calopterygidae and Lestidae (9%). As expected, the findings revealed the presence of a highly diverse Odonate assemblage, mainly represented by generalist species in the most human disturbed sectors (Pinus and Open fields) and some specialist species in the pristine forest. Two species were registered for the first time in the state of Rio Grande do Sul, Brazil: Libellula herculea Karsch, 1889 (Libellulidae) and Heteragrion luizfelipei Machado, 2006 (Heteragrionidae).

Abstract In order to understand the management of regional vegetation, numerical classification and ordination are widely used to investigate community distribution and vegetation features. In particular, two-way indicator-species analysis programs (TWINSPAN) classifies plots and species into different groups. De-trended correspondence analysis (DCA) and canonical correspondence analysis (CCA) reflects the relationship between community and site conditions. Afforestation with Larix olgensis Herry. Plantations is a suitable restoration strategy on post-agricultural fields in the Lesser Khingan Mountains. The results of this study show how these plantations develop over time to establish a reliable pathway model by measuring and clarifying the succession process. Twenty-eight L. olgensis plantations along a 48-year chronosequence of afforestation were investigated with a quadrat sampling method. Species composition, community structure attributes of diversity, and site conditions were analyzed. Communities were classified by TWINSPAN into five successional stages: immature, juvenile, mid-aged, near-mature and mature. Classifications were validated by DCA and CCA analysis. Site conditions such as soil and litter thickness, soil organic matter, soil density, and pH were measured. Successional stages varied in community composition and species population, accompanied by time from afforestation and a gradient of site conditions. This gradient showed changes in vegetation occurrence and diversity coinciding with changes in soil conditions. The study showed that L. olgensis plantations had marked predominance in growth and were associated with improved soil fertility and the formation of a stable plant community.

O instrumento de pesquisa desenvolvido por Lim, Taksande e Seaman (2012) foi usado para a coleta de dados mediante uma pesquisa exploratória e qualitativa por meio de entrevistas com profissionais de TI que trabalham em projetos de Governo Eletrônico no Governo do Estado do Rio Grande do Sul. Foram identificadas as percepções relacionadas às causas, sintomas e impactos da Dívida Técnica e sua relação com o custo e o tempo de gestão. Os resultados mostram que a Dívida Técnica está presente nos projetos de Governo Eletrônico analisados, principalmente, para priorizar o escopo e a duração, trazendo alguns riscos para a qualidade de sistemas, integridade de dados e disponibilidade de serviços governamentais. Mesmo que os resultados estejam relacionados a um caso particular, eles mostram a importância da redução da Dívida Técnica ao mesmo tempo que orçamento, abrangência e prazo são considerados.

Background:Patients with psoriatic arthritis (PsA) experience substantial functional impairment, which impacts on health-related quality of life.1Evidence from randomized clinical trials (RCTs) suggests better patient-reported functional outcomes when lower disease activity is achieved.2,3,4Objectives:To evaluate the impact of achieving DAPSA remission (REM) or low disease activity (LDA) on long term function measured by HAQ-DI. To verify predictors of achieving a minimum clinically important difference (MCID) in HAQ-DI (≤ -0.35).Methods:This is a longitudinal analysis of a real-life retrospective cohort. Inclusion criteria were adult patients fulfilling CASPAR criteria for PsA with at least 4 years of follow-up in the PsA Clinic. Demographic and clinical data were extracted from electronic medical records. Comparison of HAQ-DI variation between patients with DAPSA REM/LDA and those with moderate/high disease activity was performed using generalized estimating equation (GEE), adjusted by Bonferroni test. Correlation between HAQ-DI and DAPSA was analyzed by Spearman correlation method. A multivariate hierarchical regression model was applied in order to evaluate predictors of achieving a MCID in HAQ-DI scores.Results:Seventy-three patients were included in the analysis, of which 58.9% were female, with a median (25/75th) of 8 (3-15) years since PsA diagnosis and a mean follow up time of 6.2±1.2 years. In total, 37% of patients (N=27) presented a MCID in HAQ-DI during the follow-up. Function measured by HAQ-DI was determined by PsA disease activity measured by DAPSA (interaction test: p <0.0001) (Figure 1). A moderate and statistically significant correlation between ΔDAPSA and ΔHAQ-DI was observed (rs= 0.60; p<0.001) (Figure 2), demonstrating that a decrease in PsA disease activity was associated to improvement in function. Only patients in DAPSA REM demonstrated a constant declining in HAQ-DI scores during the 6 years of follow-up (Figure 1). White ethnicity and older age at baseline were predictors for not achieving MCID in HAQ-DI (RR 0.33 95% CI 0.16-0.67, p=0.002 and RR 0.96 95% CI 0.93-0.98, p<0.0001, respectively), while higher scores of HAQ-DI at baseline were predictors of achieving a MCID (RR 1.71 95%CI 1.12-2.60, p=0.013).Figure 1.Variation in HAQ-DI according to PsA disease activity measured by DAPSAFigure 2.Correlation between changes in PsA disease activity (ΔDAPSA) and changes in functional indices (ΔHAQ-DI) over three years of follow-upConclusion:In PsA, patients who maintained DAPSA REM/LDA over time had better long term functional outcomes. Higher HAQ-DI scores at baseline, non-white ethnicity and younger age were predictors for achieving a clinical significant improvement in HAQ-DI.References:[1]Mease P et al.

The state of conservation of Atlantic Forest in the Maquiné river basin was assessed using land cover data obtained from Landsat TM 5 satellite imagery (October 1995). The initial analysis examined the distribution of the relative areas of each land-cover type according to landscape slope classes, potential vegetation zones, and a 90 m riparian buffer. Land-cover classes were then regrouped into categories representing "low", "intermediate", and "high" degree of anthropogenic alteration. Results indicate that about 70% of the land cover of the Maquiné river basin has been highly altered as a consequence of replacement of natural forests by agriculture. Presently, a recovery process seems to be underway, contrasting with the historical trend towards deforestation. There are large areas of secondary vegetation in intermediate (34.8%) and advanced successional stages (20.2%), particularly across the range of the montane forest and of forest formations that occur at elevations higher than 800 m (high-montane dense ombrophilous forest and mixed ombrophilous forest). The geographical location at the southern limit of the Atlantic Forest stricto sensu and comparison of the results with data on the state of conservation of the Atlantic Forest in Rio Grande do Sul indicate that the Maquiné river basin is an important area for conservation. Some points regarding future research and conservation management are also discussed.

Cultural Elements

This article aims to analise how the Brazilian State of Rio Grande do Sul (RS) projects its distinctive cultural identity internationally. It does so by identifying the cultural elements in the state’s paradiplomacy from 1987 to 2014 through a sequence analysis including two elements: RS’s paradiplomatic and cultural institutions; RS’s paradiplomatic agenda. Three phases are identified in terms of space given to culture in the paradiplomacy institutional framework: expansion (1987-1994); retraction (1995- 2010); expansion (2011-2014). The phases are slightly different in terms of agenda: will but lack of means (1987-1990); focus on other issues (1991-2010); construction of an incipient agenda (2011-2014). Also, the 2012 actions to structure cultural policy at federal and state level can be seen as a factor for the agenda expansion in the last phase. However, despite the discourse around the gaúcha identity being present within the state and country, the projection further afield remains weak. Generally, the multiple changes in institutional framework and agenda show that a long-term project has not been decided on. Thus, the resulting policies are highly dependent on each governor’s vision.***Instituições e agenda de paradiplomacia cultural: O caso do Rio Grande do Sul***O objetivo deste artigo é de avaliar como o Estado do Rio Grande do Sul (RS), Brasil, projeta internacionalmente a sua identidade cultural singular. Para tanto, ele busca identificar os elementos culturais na paradiplomacia do estado de 1987 a 2014 com uma análise de trajetória composta de dois elementos: as instituições paradiplomáticas e culturais do RS; a agenda paradiplomática do RS. São identificadas três fases em termos de espaço dado à cultura na estrutura paradiplomática: expansão (1987-1994); redução (1995-2010); expansão (2011-2014). As fases relativas à agenda são um pouco diferentes: ambição, mas falta de meios (1987-1990); foco em outras temáticas (1991-2010); construção de uma agenda incipiente (2011-2014). Além disso, as ações conduzidas em 2012 para estruturar as políticas culturais em nível federal e estadual podem ser vistas como um fator da expansão da agenda na última fase.  Entretanto, apesar do discurso ao redor da identidade gaúcha ser presente dentro do estado e em nível nacional, a projeção internacional dele é fraca. De maneira geral, as múltiplas mudanças na estrutura institucional e na agenda mostram que um projeto de longo prazo não foi estabelecido. Portanto, as políticas resultantes são altamente dependentes da visão de cada governador.

Evidences of coastal erosion in Rio Grande do Sul have been obtained by three methods: (a) analysis of the long-term morphodynamics and stratigraphy of coastal barriers, (b) annual shoreline mapping using the Differential Global Positioning System (DGPS), and (c) local beach profile measurements. The first method reflects coastal erosion as continuity of the geological evolution in the last 5 ka, taking place mainly along the southern half of gentle coastal projections. The second method represents a shorter temporal scale and indicates that approximately 80% of the coast is eroding. Beach profiling has been measured in very few places that are distant from each other since the early 1990s; consequently, their results reflect local and very short time shoreline behavior. A critical evaluation of published data addressing coastal erosion in Rio Grande do Sul strongly suggests that short and long term negative balance on the sediment budget is the main cause of erosion along this coastline.

Background:Ankylosing spondylitis (AS) leads to back pain and structural damage that may result in functional impairment1. Function is usually assessed in clinical trials conducted in developed countries, with patients receiving biological therapy2,3.Objectives:To evaluate variation in the Bath Ankylosing Functional index (BASFI) over time in a AS cohort followed in a developing country. Compare the improvement in BASFI between patients achieving or not sustained (≥12 months) ASDAS-CRP remission/low disease activity (LDA). Analyze predictors for achieving a minimum clinically important improvement (MCII) in BASFI (ΔBASFI ≤ -0.6)4.Methods:This cross-sectional analysis was conducted in a retrospective cohort. Adult patients fulfilling the New York criteria for AS and followed during at least 5 years in the Spondyloarthritis clinic were included. BASFI variation (ΔBASFI) was described as median (25th/75th). Comparison of ΔBASFI between patients fulfilling or not sustained ASDAS-CRP remisson/LDA was done using the Mann-Whitney test. Hierarchical Poisson model was used to identify predictors for achieving a MCII in BASFI.Results:69 patients were analyzed, 53.6% were men, the mean age was 48.9±11.4 years, and the mean follow-up time was 6.1±0.5 years, median (25th/75th) disease duration of 10 (5-18) years; 14.5% of the patients were on biological therapy at baseline. The median (25th/75th) ΔBASFI was low: -0.1 (-1.9 /+1.1) but 46.4% (N= 32) presented a MCII in BASFI during follow-up. Patients who achieved sustained ASDAS-CRP remission/LDA had a significant improvement in BASFI over time compared with those who did not achieve this target (p=0.026) (Figure 1). Patients with higher BASFI scores at baseline had a greater probability of achieving a MCII in BASFI (RR1.13 95%CI 1.00-1.27 p=0.047). Achieving and maintaining ASDAS-CRP remission/LDA during at least 12 months increased in 82% the probability to obtain a MCII in BASFI (RR 1.82 95% CI 1.14-2.91, p=0.012). Conclusion: Patients achieving sustained ASDAS-CRP remission/LDA had better functional outcomes over time compared to those not achieving this target. Higher BASFI scores at baseline and sustained ASDAS remission/LDA were predictors of a MCII in BASFI.Figure 1.Comparison of ΔBASFI between patients who achieved or not sustained ASDASCRP remission/LDA.References:[1] Madsen OR: Stability of fatigue, pain, patient global assessment and the Bath Ankylosing Spondylitis Functional Index (BASFI) in spondyloarthropathy patients with stable disease according to the Bath Ankylosing Spondylitis Disease Activity Index (BASDAI).
