Project description:Small-scale fisheries of the Brazilian Atlantic Forest Coast (BAFC) depend on fish resources for food and income. Thus, if the catch diminishes or if fish species that are a target for fishers are overexploited or impacted, this could affect fishers' livelihoods. The exclusion of threatened fish species from the catch is believed to be a threat to small-scale fisheries, which is likely to be the case along the BAFC. Many fish species are currently listed as threatened or vulnerable, whereas there is not enough biological information available to determine the status of the majority of the other species. Failure to protect the BAFC biodiversity might negatively impact fishers' income and the regional economy of local small-scale fisheries. We collected data from 1986 to 2009 through 347 interviews and 24-h food recall surveys at seven southeastern coastal sites of the Atlantic Forest. We show that important species of consumed fish are currently threatened: of the 65 species mentioned by fishers as the most consumed fishes, 33% are decreasing and 54% have an unknown status. Thus, biological and ecological data for BAFC marine species are urgently needed, along with co-management, to promote fish conservation.

Project description:BackgroundIn small-scale fishery, information provided by fishers has been useful to complement current and past lack of knowledge on species and environment.MethodologyThrough interviews, 82 fishers from the largest fishing communities on the north and south borders of a Brazilian northeastern coastal state provided estimates of the catch per unit effort (CPUE) and rank of species abundance of their main target fishes for three time points: current year (2013 at the time of the research), 10, and 20 years past. This information was contrasted to other available data sources: scientific sampling of fish landing (2013), governmental statistics (2003), and information provided by expert fishers (1993), respectively.Principal findingsFishers were more accurate when reporting information about their maximum CPUE for 2013, but except for three species, which they estimated accurately, fishers overestimated their mean CPUE per species. Fishers were also accurate at establishing ranks of abundance of their main target species for all periods. Fishers' beliefs that fish abundance has not changed over the last 10 years (2003-2013) were corroborated by governmental and scientific landing data.ConclusionsThe comparison between official and formal landing records and fishers' perceptions revealed that fishers are accurate when reporting maximum CPUE, but not when reporting mean CPUE. Moreover, fishers are less precise the less common a species is in their catches, suggesting that they could provide better information for management purposes on their current target species.

Project description:Differences in people's beliefs can substantially impact their interpretation of a series of events. In this functional MRI study, we manipulated subjects' beliefs, leading two groups of subjects to interpret the same narrative in different ways. We found that responses in higher-order brain areas-including the default-mode network, language areas, and subsets of the mirror neuron system-tended to be similar among people who shared the same interpretation, but different from those of people with an opposing interpretation. Furthermore, the difference in neural responses between the two groups at each moment was correlated with the magnitude of the difference in the interpretation of the narrative. This study demonstrates that brain responses to the same event tend to cluster together among people who share the same views.

Project description:BackgroundAlthough fishers' knowledge has been recently considered into management programmes, there is still the need to establish a better understanding of fishers' perceptions and cognition. Fishers can provide novel information on the biology and ecology of species, which can potentially be used in the management of fisheries. The knowledge fishers have and how they classify nature is empirically based. It is common, for example, to observe that fishers' taxonomy is often represented by the generic level, one of the hierarchical categories of folk classification that is somewhat analogous to the Linnean genus, as it groups organisms of a higher rank than the folk species.In this study we compiled the knowledge fishers have on local fish, such as their folk names, diet and habitat.MethodsFive coastal communities widely distributed along the Brazilian coast were studied: two from the northeast (Porto Sauípe and Itacimirim, in Bahia State, n of interviewees?=?34), two from the southeast (Itaipu at Niterói and Copacabana at Rio de Janeiro, Rio de Janeiro State, n?=?35) and one from the south coast (Pântano do Sul, in Santa Catarina State, n?=?23). Fish pictures were randomly ordered and the same order was presented to all interviewees (n?=?92), when they were then asked about the species name and classification and its habitat and diet preferences.ResultsFishers make clusters of fish species, usually hierarchically; fishers of the coast of Brazil use mostly primary lexemes (generic names) to name fish; and fishers did not differentiate between scientific species, since the same folk generic name included two different scientific species. Fishers provide information on species to which there is scarce or no information on diet and habitat, such as Rhinobatos percellens (chola guitarfish, arraia viola or cação viola), Sphoeroides dorsalis (marbled puffer, baiacu), Mycteroperca acutirostris (comb grouper, badejo) and Dasyatis guttata (longnose stingray, arraia, arraia manteiga).Conclusionsfishers' knowledge on fish diet and fish habitat can be strategic to management, since their knowledge concentrates on the fishery target species, which are the ones under higher fishing pressure. Besides, fishers showed to have knowledge on species still poorly known to science.

Project description:It is deemed important to understand cetacean occurrence and distribution to comprehend their ecological roles. The geographical occurrence of species' niche can be used to better describe their potential distribution. The niche can be defined using environmental variables. Those variables are considered static and not affected by biological activities. The present study goal was to assess the occurrence and distribution of cetaceans along the southeastern Brazilian coast, as well as to define the fundamental and realized niche of each species and to investigate niche overlap at local scale. The environmental requirements for each species were also investigated throughout statistical tests. Sighting data were obtained through oceanographic surveys conducted between 2012 and 2015. The environmental variables available on MARSPEC and the software NicheA were used for the ecological niche modeling. A total of twelve cetacean species were identified and the potential distribution areas of the six commonest ones were defined. Even though the species presented different environmental preferences, most of them had partial overlap among niches and potential distribution areas. The environmental heterogeneity of the study area might support the co-occurrence of different species with different environmental requirements.

Project description:This study intends to give recommendations to the management of Paraty fishery in Brazil through an interplay of local and scientific knowledge. In particular, the objectives are the following: 1) to describe the Paraty fishery; 2) to compare the fishermen's local ecological knowledge with recorded fish landings and previous studies in Paraty; 3) to combine the data on local fishing and on local/Caiçara livelihoods with the SES (social-ecological systems) Model. The methods include a systematic survey of fishing in Tarituba and Praia Grande, which are located in the northern end and the central part of the Paraty municipality, respectively. For four days each month, systematic data on catches at landing points were collected, as well as macroscopic gonad analysis data for the fishes Centropomus parallelus and C. undecimalis (snook, robalo), Epinephelus marginatus (grouper, garoupa), Scomberomorus cavalla (King mackerel, cavala), and Lutjanus synagris (Lane snapper, vermelho). Spring and summer are important seasons during which some species reproduce, and the integration of fishing periods for some target species could assist in fishing management through the use of closed seasons. Fishermen could obtain complementary earnings from tourism and from the "defeso system" (closed season including a salary payment) to conserve fishing stocks. The SES model facilitates an understanding of the historical context of fishing, its economic importance for local livelihoods, the constraints from conservation measures that affect fishermen, and the management processes that already exist, such as the defeso. If used to integrate fishing with complementary activities (tourism), such a system could improve the responsibility of fishermen regarding the conservation of fish stocks.

Project description:Introduction Female adolescents living with Human Immunodeficiency Virus are a unique population facing lifelong challenges in reproductive and sexual health ranging from relational, social and legal-ethical considerations. While HIV prevalence of young females is higher than the males (4.9% versus 1%), evidence show that these adolescents in Malawi initiate sex as early as 15 years mostly with adult partners. Yet, young people are frequently reported to be reluctant to discuss sexual matters and demonstrate avoidance of direct questions on sexual issues during interviews. It is critical therefore that researchers invoke youth-friendly approaches to address these complex issues and enable these vulnerable individuals to articulate and advocate for their preferred futures. Methods This study used an innovative visual qualitative approach known as ‘my story’ book which combined image selection and sentence completion exercises to enable adolescents living with HIV to share their stories through interviews. The study involved 14 cases comprising of 14 female adolescents aged 15 to 19, 14 caregivers and 14 health providers working at HIV multidisciplinary centres in Malawi. Results The ‘my story’ book enabled in-depth exploration of the experiences and issues faced by this vulnerable population. The use of images and sentence completion exercise enabled the researcher to appreciate the type of interactions (or lack of) on sexual issues and status disclosure to significant others including sexual partners. Three themes were revealed, included creating meanings, revealing confirmatory and/or complementary evidence and enabling intergenerational research. Conclusions The ‘my story’ book captured the life experiences and needs of the female adolescents. The book assisted the participants in constructing, communicating, and controlling the articulation of their stories. It positioned female adolescents as a diverse group of social agents able to construct and reflect on their social worlds and real-life issues. This approach was highly effective in creating a youth-friendly context for reflection and revelation regarding sensitive cultural and social issues faced by this group. As such, the ‘my story’ book could be used in one-on-one counselling or provide data to inform intervention development.

Project description:IntroductionIn the modern day busy clinical practice, the communication between patient/relative and caregiver is at a minimal level. The patients and relatives feel apprehensive when advised about surgical/interventional treatment. Storytelling is such a technique of health communication made in common man language and can operate in a virtual environment. This study aims to unveil the efficacy of storytelling technique on patients undergoing Hemithyroidectomy for benign cytology.Materials & methodsA story of a lady (cartoon version), aged 25 years, with a benign solitary thyroid nodule (STN), who underwent uneventful hemithyroidectomy was depicted in this movie including the history, clinical examination, investigations, counseling, and the operative procedure, and the running time of the animation movie is 4 min. For developing this movie, high-end graphic work station and various multimedia authoring tools like Adobe Flash, Photoshop, Captivate, Maya and Final Cut Pro, were used. The story was shown to patients with clinical STN who were provisional candidates for surgery. The patients filled in the evaluation of multimedia animation questionnaire at the time of discharge.Results60 patients participated in the study. One form was disqualified due to incomplete filling. Mean age was 35.45 ± 12.8 years.55 (91.6%) were females. All patients were euthyroid. The mean weight of thyroid nodule was 40.80 ± 20.79 g. The final histopathology was colloid in the majority. All participants found the movie useful. In the questionnaire, the mean score for improved understanding of the disease was 73.9 ± 14.7, better organization of treatment was 78.6 ± 13.1 stimulated interest in the relatives was 70.8 ± 15.8 and saved unnecessary discussion with the consultant was 55.5 ± 7.8.ConclusionStory telling is a useful tool in health communication. With the widespread availability of high-speed internet and affordable mobile computing devices, story telling can be a useful tool to patients and relatives in decision making and in addition, saves valuable time of the treating consultant.

Project description:In the National Health Service (NHS) in England, traditional approaches to evidencing impact and value have an important role to play but are unlikely to demonstrate the full value of national quality improvement programmes and large-scale change initiatives in health and care. This type of work almost always takes place in complex and complicated settings, in that it involves multiple players, numerous interventions and a host of other confounding factors. Improvement work is usually emergent, with cause and effect only understood in hindsight; challenges around contribution and attribution can lead the key players to question how they can be certain that the described or observed changes are due to their intervention and would not have happened without them. In this complex environment, there is a risk of oversimplifying the observed impact and focusing instead on those things that are easier to measure, missing that which is important but more difficult to evidence. Between 2016 and 2019, an action-orientated approach, drawing on realist and development evaluation approaches, was taken to designing and testing the Impact Framework. First, we undertook a pragmatic review of tools and approaches used by others to capture and demonstrate their impact both within and outside the health and care environment. Following the identification and review of these tools and approaches, and in consultation with national improvement teams in England about their evaluation challenges and aspirations, we developed a set of underpinning principles to inform the design and build of the framework. The principles were informed and finessed following conversations with improvement teams and programme leads in NHS England with respect to the challenges that they were facing and their aspirations in terms of demonstrating their impact and learning as they worked. The 'Impact Framework' described in this article offers a practical approach to capturing the impact of improvement work at any scale, taking account of unintended outcomes, considering attribution and contribution, and using a narrative approach to uncover the difference made by improvement initiatives in rich detail. In this article, we describe how the Impact Framework has been used with one of NHS England's national programmes, Time for Care, which was delivered between 2016 and 2020. The Impact Framework continues to be used, developed and further tested by national improvement programmes being delivered by NHS England and NHS Improvement and is updated regularly. The framework has been developed to be accessible to frontline teams and is supported by a set of resources to help improvement teams and individuals to use by themselves (https://www.england.nhs.uk/sustainableimprovement/impact-framework/).

Project description:Witnesses are likely to describe a crime many times before testifying or encountering misinformation about that crime. Research examining the effect of retrieval on later suggestibility has yielded mixed results. LaPaglia and Chan manipulated whether misinformation was presented in a narrative or misleading questions, and they found that retrieval increased suggestibility when misinformation was presented in a narrative, but reduced suggestibility when the same misinformation was presented in questions. In the current study, we aimed to address why these differences occurred. Specifically, we examined whether contextual detail and narrative coherence during misinformation exposure influenced the relation between retrieval and suggestibility. Participants watched a robbery video and some were questioned about the event afterwards. They were then exposed to misinformation presented in a narrative (Experiment 1) or questions (Experiment 2) before taking a final memory test. Testing enhanced suggestibility when the misinformation phase reinstated contextual information of the event, but not when the misinformation phase included few contextual details-regardless of whether the misinformation was in a narrative or questions. In Experiment 3, disrupting narrative coherence by randomizing the order of contextual information eliminated retrieval-enhanced suggestibility. Therefore, context processing during the post-event information phase influences whether retrieval enhances or reduces eyewitness suggestibility.
