Comunidades zooplanctônicas como bioindicadoras da qualidade da água de quatro reservatórios da região semi-árida do Rio Grande do Norte

The response of zooplankton assemblages to variations in the water quality of four man-made lakes, caused by eutrophication and siltation, was investigated by means of canonical correspondence analysis. Monte Carlo simulations using the CCA eingenvalues as test statistics revealed that changes in zooplankton species composition along the environmental gradients of trophic state and abiogenic turbidity were highly significant. The species Brachionus calyciflorus, Thermocyclops sp. and Argyrodiaptomus sp. were good indicators of eutrophic conditions while the species Brachionus dolabratus, Keratella tropica and Hexarthra sp. were good indicators of high turbidity due to suspended sediments. The rotifer genus Brachionus was the most species-rich taxon, comprising five species which were associated with different environmental conditions. Therefore, we tested whether this genus alone could potentially be a better biological indicator of these environmental gradients than the entire zooplankton assemblages or any other random set of five species. The ordination results show that the five Brachionus species alone did not explain better the observed pattern of environmental variation than most random sets of five species. Therefore, this genus could not be selected as a target taxon for more intensive environmental monitoring as has been previously suggested by Attayde and Bozelli (1998). Overall, our results show that changes in the water quality of man-made lakes in a tropical semi-arid region have significant effects on the structure of zooplankton assemblages that can potentially affect the functioning of these ecosystems

FLORÍSTICA E ESTRUTURA DO COMPONENTE ARBÓREO E RELAÇÃO COM VARIÁVEIS AMBIENTAIS EM UM REMANESCENTE FLORESTAL EM CAMPOS NOVOS - SC

O presente estudo objetivou conhecer os padrões da composição florística e estrutural do componente arbóreo de um trecho de remanescente de Floresta Ombrófila Mista Montana em Campos Novos - SC e determinar as variáveis ambientais que influenciam estes padrões. Para isso, foi amostrado 1 ha de floresta por meio de 50 parcelas de 10 × 20 m dispostas de forma sistemática, distanciada 30 m entre si, no remanescente florestal. Dentro das parcelas foram identificados e mensurados (circunferência medida a altura do peito, CAP, e altura total) CAP, e altura total) todos os indivíduos arbóreos vivos com CAP ≥ 15,7 cm. Os dados ambientais relacionados às propriedades químicas e físicas dos solos e à topografia também foram coletados em cada parcela. Foram calculados o índice de Shannon-Wiener (H’), a equabilidade de Pielou (J’) e os estimadores fitossociológicos. A organização florístico-estrutural do fragmento foi analisada por meio de uma NMDS (Nonmetric multidimensional scalling). As variáveis ambientais foram ajustadas a posteriori à ordenaçã o produzida, sendo aquelas significativas (p < 0,05) plotadas na forma de vetores. Foram amostrados 1.027 indivíduos, que totalizaram uma área basal de 43,57 m2, distribuídos em 88 espécies e 41 famílias botânicas. A diversidade do remanescente estudado foi relativamente alta (H’=3,59) e a dominância baixa (J’=0,80). A espécie de maior VI foi Araucaria angustifolia (Bertol.) Kuntze (14,44%). A análise multivariada NMDS indicou um gradiente florístico-estrutural relacionado à cota média (altitude), saturação de bases, pH e teores de P nos solos.

Experiences of care and adjustment to change in caregivers of children with autoimmune encephalitis: an interpretative phenomenological analysis

Background: Autoimmune encephalitis (AE) occurs in response to an antibody-mediated central nervous system disease and can lead to significant neurodisability. Prior research on family adjustment has described a reciprocal relationship between caregiver functioning, distress and clinical outcome in parents and children with encephalitis. There has been no previous research exploring the experiences of caregivers with a child with AE. Aims: To explore the perspectives of parents and/or caregivers with a child diagnosed with AE regarding (i) their own adjustment from hospital admission to post-discharge, and (ii) their experiences of care and service provision. Methods: A purposive sampling approach was used. Five parents of children with AE participated in a semi-structured interview exploring their experiences of caring for their child and service provision during acute care and post-discharge. Interpretative Phenomenological Analysis (IPA) was used to analyse the transcripts. Main findings and conclusions: Four shared super-ordinate themes with related subthemes emerged: (a) uncertainty, (b) managing our recovery, (c) changes in my child, (d) experiences of service provision. Participants reported emotional distress, often underpinned by recurrent experiences of uncertainty, and ‘loss’ of the previous child, and mediated by coping strategies and social support. While an overall positive experience of inpatient services was reported, parents often perceived post-discharge services as lacking in co-ordination, communication and formal follow-up, resulting in unmet support needs. Implications and recommendations for services, practitioners and future research are discussed.

Agroclimatic classification: numerical- taxonomic procedures - a review.

The paper catalogues the procedures and steps involved in agroclimatic classification. These vary from conventional descriptive methods to modern computer-based numerical techniques. There are three mutually independent numerical classification techniques, namely Ordination, Cluster analysis, and Minimum spanning tree; and under each technique there are several forms of grouping techniques existing. The vhoice of numerical classification procedure differs with the type of data set. In the case of numerical continuous data sets with booth positive and negative values, the simple and least controversial procedures are unweighted pair group method (UPGMA) and weighted pair group method (WPGMA) under clustering techniques with similarity measure obtained either from Gower metric or standardized Euclidean metric. Where the number of attributes are large, these could be reduced to fewer new attributes defined by the principal components or coordinates by ordination technique. The first few components or coodinates explain the maximum variance in the data matrix. These revided attributes are less affected by noise in the data set. It is possible to check misclassifications using minimum spanning tree.

New testament evidence for ordaining women in the catholic church: evaluating claims in inter insigniores and ordinatio sacerdotalis

This Master's Thesis will re-evaluate the conclusions of the Vatican on the issue of women's ordination, as presented in the documents Inter Insigniores and Ordinatio Sacerdotalis, by researching the discoveries of scriptural scholarship on the significance of women in the New Testament ministries. The essential question is, are the two previously mentioned documents authoritative when they exclude women from priesthood on the basis of Scripture? Special emphasis is on the unprejudiced rereading of the status of women in the ministry of Jesus and the early church communities. The research proved that there is no significant evidence in the New Testament to reserve ordained ministries in the Church to men only.

Agenda för samverkan eller verksamhetens agenda? Om professionellas erfarenheter av samverkan enligt samordnad individuell plan (SIP)

Agenda for collaboration or an agency agenda? Professionals’ experiences of colla­boration according to a coordinated individual plan (CIP) An increasing number of children and adolescents develop complex needs that require simultaneous action by different professionals. Several reports state that efforts for these children and adolescents have become increasingly specialized and fragmented. Since 2010, there are statutory requirements for collaboration according to a coordinated individual plan (SIP) between health care and social services. Pre-school and school can after regional agreement be involved in the co-ordination as equal partner. Collaboration in line with CIP is expected to offset the fragmentation for benefit of the service users’ ability to monitor and comprehend interventions. The aim was to investigate professionals’ experiences of CIP. The study consists of qualitative analysis of 12 focus group interviews with a total of 71 staff with different professions in health care, education and social services about their experiences of CIP. The results indicate that the participants act according to their core mission: nurturing, teaching and investigation. Two main categories with four sub-categories each appeared in the analysis. The main category, hindering factors, contains the categories: different mandates and requirements, requirements for presence initiative, questioning and censure, and timelines and prioritization. The main category of facilitating factors contains the categories: similar interpretation of common agreement, mutual respect and shared learning, common terminology and documentation, and willingness to collaborate. The analysis indicate that CIP was perceived as alternating between, on the one hand, a pro-active and service-focused tool, and on the other hand, a competing and compelling professional instrument.

Social participation and interventions supporting teenagers and young adults living with developmental coordination disorder (DCD): results from a Scoping Review

Background: The impact of Developmental Coordination Disorder (DCD) on teenagers’ and young adults’ participation is not well documented. This article aims to synthesize the current knowledge on social participation, which is the performance of an individual in realizing his daily activities and social roles within its life environment. Strategies and interventions to support youths (15-25 years old) with DCD were also synthesized. Methods: A scoping review interrogating three databases and using ‘snowballing techniques’ was performed to identify both scientific and grey literature published between 2004 and 2014. Over 1000 documents were screened and 57 were read in full; 28 met inclusion criteria. A charting form based on 12 life habits described in the Disability Creation Process (DCP) and developed by two reviewers was used to extract data and report the results. Results: All life habits were reported to be affected for teenagers and young adults with DCD, with education and interpersonal relationships being the most frequently discussed. During adolescence and adulthood, new tasks and subsequent difficulties emerge, such as driving. Mental health difficulties emerged as a key theme. Few strategies and interventions were described to support social participation of youths with DCD. Conclusion: Many life habits are challenging for youths with DCD, but few evidence-based strategies and interventions have been designed to help them to increase their social participation.

A comparative study of the species composition of discards from five fisheries from the Algarve (southern Portugal)

Discards from five of the most important fisheries (crustacean trawling, fish trawling, demersal purse seining, pelagic purse seining and trammel netting) in southern Portugal were studied and compared. A total of 236 species of all taxa were discarded, with fish and cephalopods accounting for more than 90% of the discarded biomass, except trammel nets (81%). Although there was some overlapping of species, multivariate analysis using cluster analysis for classification and multidimensional scaling (MDS) for ordination, showed that there were significant differences between the five gears in terms of species composition and biomasses discarded, with the least similarity between crustacean trawling and all other fishing operations. The differences between fisheries were probably as a result of a combination of gear selectivity and depth fished. The results suggest that discarding practices are likely to have different, yet significant impacts on the marine ecosystem, warranting further studies on the fate of discards, the factors influencing discarding and mitigation.

Ecological quality assessment of transitional waters based on fish assemblages in Portuguese estuaries: The Estuarine Fish Assessment Index (EFAI)

The assessment of water quality has changed markedly worldwide over the last years, especially in Europe due to the implementation of the Water Framework Directive. Fish was considered a key-element in this context and several fish-based multi-metric indices have been proposed. In this study, we propose a multi-metric index, the Estuarine Fish Assessment Index (EFAI), developed for Portuguese estuaries, designed for the overall assessment of transitional waters, which could also be applied at the water body level within an estuary. The EFAI integrates seven metrics: species richness, percentage of marine migrants, number of species and abundance of estuarine resident species, number of species and abundance of piscivorous species, status of diadromous species, status of introduced species and status of disturbance sensitive species. Fish sampling surveys were conducted in 2006, 2009 and 2010, using beam trawl, in 13 estuarine systems along the Portuguese coast. Most of the metrics presented a high variability among the transitional systems surveyed. According to the EFAI values, Portuguese estuaries presented a "Good" water quality status (except the Douro in a particular year). The assessments in different years were generally concordant, with a few exceptions. The relationship between the EFAI and the Anthropogenic Pressure Index (API) was not significant, but a negative and significant correlation was registered between the EFAI and the expert judgement pressure index, at both estuary and water body level. The ordination analysis performed to evaluate similarities among North-East Atlantic Geographical Intercalibration Group (NEAGIG) fish-based indices put in evidence four main groups: the French index, since it is substantially different from all the other indices (uses only four metrics based on densities); indices from Ireland, United Kingdom and Spain (Asturias and Cantabria); the Dutch and German indices; and the indices of Belgium. Portugal and Spain (Basque country). The need for detailed studies, including comparative approaches, on several aspects of these assessment tools, especially in what regards their response to anthropogenic pressures was stressed.

An exploration of treatment burden and patient capacity in people with stroke

Background and aims: Advances in modern medicine have led to improved outcomes after stroke, yet an increased treatment burden has been placed on patients. Treatment burden is the workload of health care for people with chronic illness and the impact that this has on functioning and well-being. Those with comorbidities are likely to be particularly burdened. Excessive treatment burden can negatively affect outcomes. Individuals are likely to differ in their ability to manage health problems and follow treatments, defined as patient capacity. The aim of this thesis was to explore the experience of treatment burden for people who have had a stroke and the factors that influence patient capacity. Methods: There were four phases of research. 1) A systematic review of the qualitative literature that explored the experience of treatment burden for those with stroke. Data were analysed using framework synthesis, underpinned by Normalisation Process Theory (NPT). 2) A cross-sectional study of 1,424,378 participants >18 years, demographically representative of the Scottish population. Binary logistic regression was used to analyse the relationship between stroke and the presence of comorbidities and prescribed medications. 3) Interviews with twenty-nine individuals with stroke, fifteen analysed by framework analysis underpinned by NPT and fourteen by thematic analysis. The experience of treatment burden was explored in depth along with factors that influence patient capacity. 4) Integration of findings in order to create a conceptual model of treatment burden and patient capacity in stroke. Results: Phase 1) A taxonomy of treatment burden in stroke was created. The following broad areas of treatment burden were identified: making sense of stroke management and planning care; interacting with others including health professionals, family and other stroke patients; enacting management strategies; and reflecting on management. Phase 2) 35,690 people (2.5%) had a diagnosis of stroke and of the 39 co-morbidities examined, 35 were significantly more common in those with stroke. The proportion of those with stroke that had >1 additional morbidities present (94.2%) was almost twice that of controls (48%) (odds ratio (OR) adjusted for age, gender and socioeconomic deprivation; 95% confidence interval: 5.18; 4.95-5.43) and 34.5% had 4-6 comorbidities compared to 7.2% of controls (8.59; 8.17-9.04). In the stroke group, 12.6% of people had a record of >11 repeat prescriptions compared to only 1.5% of the control group (OR adjusted for age, gender, deprivation and morbidity count: 15.84; 14.86-16.88). Phase 3) The taxonomy of treatment burden from Phase 1 was verified and expanded. Additionally, treatment burdens were identified as arising from either: the workload of healthcare; or the endurance of care deficiencies. A taxonomy of patient capacity was created. Six factors were identified that influence patient capacity: personal attributes and skills; physical and cognitive abilities; support network; financial status; life workload, and environment. A conceptual model of treatment burden was created. Healthcare workload and the presence of care deficiencies can influence and be influenced by patient capacity. The quality and configuration of health and social care services influences healthcare workload, care deficiencies and patient capacity. Conclusions: This thesis provides important insights into the considerable treatment burden experienced by people who have had a stroke and the factors that affect their capacity to manage health. Multimorbidity and polypharmacy are common in those with stroke and levels of these are high. Findings have important implications for the design of clinical guidelines and healthcare delivery, for example co-ordination of care should be improved, shared decision-making enhanced, and patients better supported following discharge from hospital.

The Commission, the Single Market and the Crisis: The Limits of Purposeful Opportunism

The economic and financial crisis opened a window of opportunity to place the Single Market back on top of the European agenda as part of a two-tiered crisis response, which also included reinforced financial supervision and economic co-ordination. We argue that the Commission acted as a ‘purposeful opportunist’ in both tiers; but whereas in economic governance issues there was breakthrough change in the Commission's achievements and competences, in the Single Market realm policy change was fairly modest. Using process tracing analysis our goal is to explain why the Commission did not succeed in furthering a genuine Single Market reform. Our findings suggest that the Commission's entrepreneurship was constrained by the limited salience of Single Market issues in the crisis context and by the lack of actual political commitment from the other relevant stakeholders. Thus, our research highlights the limits of the Commission's opportunistic behaviour in less advantageous circumstances.

Geographical and environmental correlates of big and small game in Andalusia (southern Spain)

In Andalusia, southern Spain, each game estate applies its own rules and presents its results in annual hunting reports, which have been mandatory for Spanish game estates since 1989. We used the information about hunting yields, included in 32134 annual hunting reports produced during the period 1993/94 to 2001/02 by 6049 game estates, to determine the current distribution of hunting yields of big and small game species in Andalusia. Using generalised linear models and a geographic information system, we determined the most favourable municipalities to big and small game, respectively, and delimited potential areas to attain good hunting yields for big and small game at a 1-km2 resolution. Municipalities and areas favourable to big game are mainly located in the Sierra Morena and the westernmost fringe of the Betic Range, while those favourable to small game occupy the upper Guadalquivir River valley. There is a clear segregation between big and small game species according to the physiography and land uses of the territory. Big game species are typical of Mediterranean woodland areas, while the most emblematic small game species prefer agricultural areas. Our results provide a territorial ordination of hunting yields in southern Spain and have several potential applications in strategic planning for hunting activities and biodiversity conservation in Andalusia that can be extrapolated to other regions.
