Not just what they want, but why they want it: Traditional market research to deep customer insights

Purpose This paper explores advantages and disadvantages of both traditional market research and deep customer insight methods in order to lay the platform for revealing how a relationship between these two domains could be optimised during firm-based innovation. Design/methodology/approach The paper reports on an empirical research study conducted with thirteen Australian based firms engaged in a design-led approach to innovation. Firms were facilitated through a design-led approach where the process of gathering deep customer insights was isolated and investigated further in comparison to traditional market research methods. Findings Results show that deep customer insight methods are able to provide fresh, non-obvious ways of understanding customer needs, problems and behaviours that can become the foundation of new business opportunities. Findings concluded that deep customer insights methods provide the critical layer to understand why customers do and don’t engage with businesses. Revealing why was not accessible in traditional market research methods. Research limitations/implications The theoretical outcome of this study is a complementary methods matrix, providing guidance on appropriate implementation of research methods in accordance with a project’s timeline to optimise the complementation of traditional market research methods with design-led customer engagement methods. Practical implications Deep customer insight methods provide fresh, non-obvious ways of understanding customer needs, problems and behaviours that can become the foundation of new business opportunities. It is hoped that those in a position of data collection are encouraged to experiment and use deep customer insight methods to connect with their customers on a meaningful level and translate these insights into value. Originality/value This paper provides original value to a new understanding how design techniques can be applied to compliment and strengthen existing market research strategies. This is crucial in an era where business competition hinges on a subtle and often intimate understanding of customer needs and behaviours.

Incorporating process variability into stormwater quality modelling

Process variability in pollutant build-up and wash-off generates inherent uncertainty that affects the outcomes of stormwater quality models. Poor characterisation of process variability constrains the accurate accounting of the uncertainty associated with pollutant processes. This acts as a significant limitation to effective decision making in relation to stormwater pollution mitigation. The study undertaken developed three theoretical scenarios based on research findings that variations in particle size fractions <150µm and >150µm during pollutant build-up and wash-off primarily determine the variability associated with these processes. These scenarios, which combine pollutant build-up and wash-off processes that takes place on a continuous timeline, are able to explain process variability under different field conditions. Given the variability characteristics of a specific build-up or wash-off event, the theoretical scenarios help to infer the variability characteristics of the associated pollutant process that follows. Mathematical formulation of the theoretical scenarios enables the incorporation of variability characteristics of pollutant build-up and wash-off processes in stormwater quality models. The research study outcomes will contribute to the quantitative assessment of uncertainty as an integral part of the interpretation of stormwater quality modelling outcomes.

Service-learning through multiple client-sponsored projects in an MBA marketing course

This paper outlines an approach for teaching Marketing Principles in an MBA course through service-learning to enable adult learners to connect the lectures’ marketing content to a real-world marketing project. During the course, 40 students in groups of four to five individuals were involved in eight different client-sponsored marketing projects executed simultaneously. The rationale, planning and management of this approach utilised current research on service-learning, living cases and client-sponsored projects in marketing education. The experimental curriculum design is presented in a timeline that mirrors the preparation and management of the group projects and the considerations to be taken into account when initiating and facilitating the projects. Reflections from this iteration of the service-learning design suggest the importance of: detailed project planning, the involvement of students in choosing the projects, the introduction of forms and feedback loops, the role of the instructor in facilitating the students and managing expectations, and the role of the company representative in supporting the groups.

Establishment of an Australian mild onion industry - the sensory component

In recent years, there has been increasing interest from growers, merchants, supermarkets and consumers in the establishment of a national mild onion industry. Imperative to the success of the emergent industry is the application of the National Mild Onion Certification Scheme that will establish standards and recommendations to be met by growers to allow them to declare their product as certified mild onions. The use of sensory evaluation techniques has played an imperative role throughout the project timeline that has also included varietal evaluation, evaluation of current agronomic practices and correlation of chemical analysis data. Raw onion consumer acceptance testing on five different onion varieties established preferences amongst the varieties for odour, appearance, flavour, texture and overall and differences in the level of pungency and aftertaste perceived. Demographic information was obtained regarding raw and cooked onion use, frequency of consumption and responses to the idea of a mild, less pungent onion. Additionally, focus groups were conducted to further investigate consumer attitudes to onions. Currently, a trained onion panel is being established to evaluate several odour, flavour and aftertaste attributes. Sample assessments will be conducted in January 2004 and correlated with chemical analyses that will hopefully provide the corner-stone for the anticipated Certification Scheme.

VisArchive: a time and relevance based visual interface for searching, browsing, and exploring project archives

Background Project archives are becoming increasingly large and complex. On construction projects in particular, the increasing amount of information and the increasing complexity of its structure make searching and exploring information in the project archive challenging and time-consuming. Methods This research investigates a query-driven approach that represents new forms of contextual information to help users understand the set of documents resulting from queries of construction project archives. Specifically, this research extends query-driven interface research by representing three types of contextual information: (1) the temporal context is represented in the form of a timeline to show when each document was created; (2) the search-relevance context shows exactly which of the entered keywords matched each document; and (3) the usage context shows which project participants have accessed or modified a file. Results We implemented and tested these ideas within a prototype query-driven interface we call VisArchive. VisArchive employs a combination of multi-scale and multi-dimensional timelines, color-coded stacked bar charts, additional supporting visual cues and filters to support searching and exploring historical project archives. The timeline-based interface integrates three interactive timelines as focus + context visualizations. Conclusions The feasibility of using these visual design principles is tested in two types of project archives: searching construction project archives of an educational building project and tracking of software defects in the Mozilla Thunderbird project. These case studies demonstrate the applicability, usefulness and generality of the design principles implemented.

Influence of uncertainty inherent to heavy metal build-up and wash-off on stormwater quality

Uncertainty inherent to heavy metal build-up and wash-off stems from process variability. This results in inaccurate interpretation of stormwater quality model predictions. The research study has characterised the variability in heavy metal build-up and wash-off processes based on the temporal variations in particle-bound heavy metals commonly found on urban roads. The study outcomes found that the distribution of Al, Cr, Mn, Fe, Ni, Cu, Zn, Cd and Pb were consistent over particle size fractions <150µm and >150µm, with most metals concentrated in the particle size fraction <150µm. When build-up and wash-off are considered as independent processes, the temporal variations in these processes in relation to the heavy metals load are consistent with variations in the particulate load. However, the temporal variations in the load in build-up and wash-off of heavy metals and particulates are not consistent for consecutive build-up and wash-off events that occur on a continuous timeline. These inconsistencies are attributed to interactions between heavy metals and particulates <150µm and >150µm, which are influenced by particle characteristics such as organic matter content. The behavioural variability of particles determines the variations in the heavy metals load entrained in stormwater runoff. Accordingly, the variability in build-up and wash-off of particle-bound pollutants needs to be characterised in the description of pollutant attachment to particulates in stormwater quality modelling. This will ensure the accounting of process uncertainty, and thereby enhancing the interpretation of the outcomes derived from modelling studies.

Functional Imagery Training to reduce snacking: Testing a novel motivational intervention based on Elaborated Intrusion theory

Functional Imagery Training (FIT) is a new theory-based, manualized intervention that trains positive goal imagery. Multisensory episodic imagery of proximal personal goals is elicited and practised, to sustain motivation and compete with less functional cravings. This study tested the impact of a single session of FIT plus a booster phone call on snacking. In a stepped-wedge design, 45 participants who wanted to lose weight or reduce snacking were randomly assigned to receive a session of FIT immediately or after a 2-week delay. High-sugar and high-fat snacks were recorded using timeline follow back for the previous 3 days, at baseline, 2 and 4 weeks. At 2 weeks, snacking was lower in the immediate group than in the delayed group, and the reduction after FIT was replicated in the delayed group between 2 and 4 weeks. Frequencies of motivational thoughts about snack reduction rose following FIT for both groups, and this change correlated with reductions in snacking and weight loss. By showing that FIT can support change in eating behaviours, these findings show its potential as a motivational intervention for weight management.

Coping style and ecstasy use motives as predictors of current mood symptoms in ecstasy users

Background Elevated depressive and anxiety symptoms during childhood and adolescence have been associated with greater risk of later ecstasy use. Ecstasy users have reported using ecstasy to reduce depression or worry, or to escape. While these findings suggest that some people use ecstasy as a form of self-medication, limited research has been conducted examining the relationship between affective symptoms, coping styles and drug use motives in ecstasy users. This cross-sectional study aimed to determine if coping style and/or ecstasy use motives are associated with current mood symptoms in ecstasy users. Methods A community sample (n = 184) of 18–35 year olds who had taken ecstasy at least once in the past 12 months completed self-report measures of depression, anxiety, ecstasy use motives and coping styles. Timeline followback methods were used to collect information on lifetime ecstasy, recent drug use and life stress. Trauma exposure was measured using the Composite International Diagnostic Interview—Trauma List. Results Coping motives for ecstasy use and an emotion-focused coping style were significantly associated with current depressive and anxiety symptoms. Emotion-focused coping mediated the relationship between a history of trauma and current anxiety symptoms and moderated the relationship between recent stressful life events and current depressive symptoms. Conclusions These findings highlight the importance of interventions targeting motives for ecstasy use, and providing coping skills training for managing stressful life events among people with co-occurring depressive/anxiety symptoms and ecstasy use.

The prehistory of Suomussalmi, eastern Finland; the first billion years as revealed by isotopes and the composition of granitoid suites

The four papers summarized in this thesis deal with the Archean and earliest Paleoproterozoic granitoid suites observed in the Suomussalmi district, eastern Finland. Geologically, the area belongs to the Kianta Complex of the Western Karelian Terrane in the Karelian Province of the Fennoscandian shield. The inherited zircons up to 3440 Ma old together with Sm Nd and Pb Pb data confirm the existence of previously anticipated Paleoarchean protocrust in Suomussalmi. The general timeline of granitoid magmatism is similar to that of the surrounding areas. TTG magmatism occurred in three distinct phases: ca 2.95 Ga, 2.83 2.78 Ga and 2.76 2.74 Ga. In Suomussalmi the TTGs sensu stricto (K2O/Na2O less than 0.5) belong to the low-HREE type and are interpreted as partial melts of garnet amphibolites, which did not significantly interact with mantle peridotites. Transitional TTGs (K2O/Na2O more than 0.5), present in Suomussalmi and absent from surrounding areas, display higher LILE concentrations, but otherwise closely resemble the TTGs sensu stricto and indicate that recycling of felsic crust commenced in Suomussalmi 200 Ma earlier than in surrounding areas. The youngest TTG phase was coeval with the intrusion of the Likamännikkö quartz alkali feldspar syenite (2741 ± 2 Ma) complex. The complex contains angular fragments of ultrabasic rock, which display considerable compositional heterogeneity and are interpreted as cumulates containing clinopyroxene (generally altered to actinolite), apatite, allanite, epidote, and albite. The quartz alkali feldspar syenite cannot be regarded as alkaline sensu stricto, despite clear alkaline affinities. Within Likamännikkö there are also calcite carbonatite patches, which display mantle-like O- and C-isotope values, as well as trace element characteristics consistent with a magmatic origin, and could thus be among the oldest known carbonatites in the world. Sanukitoid (2.73 2.71 Ga) and quartz diorite suites (2.70 Ga) overlap within error margins and display compositional similarities, but can be differentiated from each other on the basis of higher Ba, K2O and LREE contents of the sanukitoids. The Likamännikkö complex, sanukitoids and quartz diorites are interpreted as originating from the metasomatized mantle and mark the diversification of the granitoid clan after 200 Ma of evolution dominated by the TTG suite. Widespread migmatization and the intrusion of anatectic leucogranitoids as dykes and intrusions of varying size took place at 2.70 2.69 Ga, following collisional thickening of the crust. The leucogranitoids and leucosomes of migmatized TTGs are compositionally alike and characterized by high silica contents and a leucocratic appearance. Due to compositional overlap, definitive discrimination between leucogranitoids and transitional TTGs requires isotope datings and/or knowledge of field relationships. Leucogranitoids represent partial melts of the local TTGs, both the sensu stricto and transitional types, mostly derived under water fluxed conditions, with possible fluid sources being late sanukitoids and quartz diorites as well as dehydrating lower crust. The Paleoproterozoic 2.44 2.39 Ga A-type granitoids of the Kianta Complex emplaced in an extensional environment are linked to the coeval and more widespread mafic intrusions and dykes observed over most of the Archean nucleus of the Fennoscandian shield. The A-type intrusions in the Suomussalmi area are interpreted as partial melts of the Archean lower crust and display differences in composition and magnetite content, which indicate differences in the composition and oxidation state of the source.

Valkolakki vai haalarit, vaiko molemmat : Koulutuspolitiikan vaikuttajien näkemykset toisen asteen kehityksestä

In the present research Finnish education policy-makers describe the transformation in upper secondary education in the 1990s. They answered questions related to equality and all-round education. The timeline of the research extends from the early development of the welfare state and equality policy to the 2000s. Its focus is on upper secondary education, which, in this paper, denotes general upper secondary education and vocational upper secondary education. The chronological analysis proceeds from the education committee of 1971 up to the youth education experiment of the 1990s. The voices of the then policy-makers are heard in this research. They were the ones who planned the reforms and/or made the decisions. This being the case, the interviewees include cabinet ministers, permanent secretaries, representatives of organisations and the research community as well as civil servants. The research material can be construed as contextual interpretations of the past, influenced by both the times and places where the narrations were given. The persons interviewed described their experiences and views on education policy. In their narratives they illustrated the transformation that occurred in relation to equality and all-round education. The narrative interviews painted a picture of the upper secondary education transformation and the matriculation examination as having a slowing effect on education policy reforms. It was not until the 1990s when the said examination began to make a difference to students in vocational upper secondary education Those interviewed named the persons who, in their opinion, had the most say in Finnish education policy. This list comprised a small circle of people who more or less agreed on the grand values of education policy, i.e. all-round education and equality. Only a small minority represented a radical view of equality, being true believers in universal upper secondary education implemented in accordance with comprehensive school reform. Finnish education policy was led from the perspective of traditional conception of equality from the 1970s to the 1980s. The transformation finally occurred in the 1990s when equality was understood to mean individual needs and the right to choose. As was the case with matriculation education, the insistence on all-round education also hampered the development of universal upper secondary education. The interviews revealed that any attempts to increase the academic syllabus of vocational education caused organisations as well as other policy-makers to oppose such development well into the 1980s. It was not until the youth education experiment of the 1990s that vocational education finally carved a path to higher education, when the polytechnic schools were made permanent. Three principal groups of key players emerged in the research: ministers of education, civil servants and organisations. The research showed that the ministers and civil servant education policy-makers of the 1990s also included only handful women. The circle of policy-makers was small and represented similar schools of thought. In the 1970s era of government committees, representatives of organisations actively participated in education policy. When the committee establishment was discontinued, this eliminated lobbying venues for the organisations. Nonetheless, the organisations regained their policymaking status in the 1990s. New lobbying organisations included the Finnish Entrepreneurs and the Union of Finnish Upper Secondary School Students. However, in contrast to the 1970s, only rarely would individuals rise from the ranks of organisations to the cadre of policy-makers. The interviewees had a twofold view of neo-liberalism Contrary to other policy-makers, representatives of the research community and organisations concur that neo-liberalism did exist in education policy decision-making in the 1990s.

Application of participatory rural appraisal (PRA) techniques in the verification of fisheries data and trend on Lake Kainji

After several years of surveys on the Kainji Lake fisheries activities by the Nigerian German Kainji Lake Fish promotion Project (KLFPP) trends regarding catches, yield and other parameter begin to emerge. However, it became obvious that some of the data were not quite as accurate as they were believed to be. Looking at the different editions of the statistical bulletin of Kainji Lake, concerning one given fisheries parameter, sometimes it is possible to reveal inconsistencies and unexplained trends. As compared to the survey method, PRA is primarily for analysis of differences in local phenomenon and processes. Therefore, PRA was used as a complementary tool to enhance the knowledge on issues like fisher women, entrepreneurs, gear ownership structure, mode of operation by owners of large gear number, preference in the use of twine and nylon gill nets, and reasons for misinformation on the number of fishing equipment owned by entrepreneurs, which cannot be done with frame survey. PRA techniques like timeline, mapping, seasonal calendar, transect walk and key informant interviews were utilized in the study process

Models of the Oxygen-Evolving Complex of Photosystem II

In the five chapters that follow, I delineate my efforts over the last five years to synthesize structurally and chemically relevant models of the Oxygen Evolving Complex (OEC) of Photosystem II. The OEC is nature’s only water oxidation catalyst, in that it forms the dioxygen in our atmosphere necessary for oxygenic life. Therefore understanding its structure and function is of deep fundamental interest and could provide design elements for artificial photosynthesis and manmade water oxidation catalysts. Synthetic endeavors towards OEC mimics have been an active area of research since the mid 1970s and have mutually evolved alongside biochemical and spectroscopic studies, affording ever-refined proposals for the structure of the OEC and the mechanism of water oxidation. This research has culminated in the most recent proposal: a low symmetry Mn₄CaO₅ cluster with a distorted Mn₃CaO₄ cubane bridged to a fourth, dangling Mn. To give context for how my graduate work fits into this rich history of OEC research, Chapter 1 provides a historical timeline of proposals for OEC structure, emphasizing the role that synthetic Mn and MnCa clusters have played, and ending with our Mn₃CaO₄ heterometallic cubane complexes.

In Chapter 2, the triarylbenzene ligand framework used throughout my work is introduced, and trinuclear clusters of Mn, Co, and Ni are discussed. The ligand scaffold consistently coordinates three metals in close proximity while leaving coordination sites open for further modification through ancillary ligand binding. The ligands coordinated could be varied, with a range of carboxylates and some less coordinating anions studied. These complexes’ structures, magnetic behavior, and redox properties are discussed.

Chapter 3 explores the redox chemistry of the trimanganese system more thoroughly in the presence of a fourth Mn equivalent, finding a range of oxidation states and oxide incorporation dependent on oxidant, solvent, and Mn salt. Oxidation states from Mn^II₄ to Mn^IIIMn^IV₃ were observed, with 1-4 O^2– ligands incorporated, modeling the photoactivation of the OEC. These complexes were studied by X-ray diffraction, EPR, XAS, magnetometry, and CV.

As Ca²⁺ is a necessary component of the OEC, Chapter 4 discusses synthetic strategies for making highly structurally accurate models of the OEC containing both Mn and Ca in the Mn₃CaO₄ cubane + dangling Mn geometry. Structural and electrochemical characterization of the first Mn₃CaO₄ heterometallic cubane complex— and comparison to an all-Mn Mn₄O₄ analog—suggests a role for Ca²⁺ in the OEC. Modification of the Mn₃CaO₄ system by ligand substitution affords low symmetry Mn₃CaO₄ complexes that are the most accurate models of the OEC to date.

Finally, in Chapter 5 the reactivity of the Mn₃CaO₄ cubane complexes toward O- atom transfer is discussed. The metal M strongly affects the reactivity. The mechanisms of O-atom transfer and water incorporation from and into Mn₄O₄ and Mn₄O₃ clusters, respectively, are studied through computation and ¹⁸O-labeling studies. The μ3-oxos of the Mn₄O₄ system prove fluxional, lending support for proposals of O^2– fluxionality within the OEC.

Avaliação do copolímero de acrilonitrila e 2-vinil-2-oxazolina na eficiência de inibição de corrosão química em meio salino

Processos corrosivos geram perdas incalculáveis para a sociedade. Existe, portanto, uma incessante busca por métodos cada vez mais econômicos, eficientes e que não gerem impacto ao meio-ambiente. Polímeros heterocíclicos são macromoléculas de elevada performance que vêm sendo estudados como inibidores de corrosão por atenderem as premissas citadas acima. Neste trabalho realizou-se a modificação química da poliacrilonitrila com a incorporação de grupos 2-vinil-2-oxazolina no teor teórico de 20%. O copolímero obtido e a poliacrilonitrila não modificada foram caracterizados por espectroscopia na região do infravermelho e avaliados como inibidores de corrosão para alumínio e aço carbono em meio salino em temperatura de 60C. As concentrações utilizadas foram de 20, 50, 100 e 200 ppm e os períodos de checagem: 1, 2, 3 e 4 semanas. Os polímeros estudados apresentaram atividade inibitória de corrosão apenas para o aço carbono. Para o alumínio, o ensaio em branco apresentou a menor taxa de corrosão dentre todos os ensaios realizados

Território, rede e cultura da tradição: o fado do século XIX no mundo do século XXI

A história do fado começa no século XIX e está entrelaçada por diversas teorias sobre suas origens, as quais continuam sendo debatidas até hoje. Inserido a Lista Representativa do Patrimônio Cultural Imaterial da Humanidade pela Organização das Nações Unidas para a Educação, a Ciência e a Cultura (UNESCO) em 2011, o fado é considerado como o principal símbolo musical de Portugal, presente na vida quotidiana social e cultural de muitos portugueses, tendo superado fronteiras geográficas, sociais, culturais, políticas e econômicas. Considera-se neste trabalho a importância do Império Português e de suas colônias, como Moçambique, Angola, Brasil e Goa, como contributos para o início do processo da disseminação do fado pelo mundo, levando para os territórios ultramarinos fragmentos da cultura portuguesa a partir do século XV, bem como o desenvolvimento do capitalismo e a fluidificação das fronteiras que, através da mídia, globalizaram o fado, mundializando-o, e catalisando nele o processo de mestiçagem entre as músicas das mais diferentes classificações (VALENTE, 2007:94), e, a influência dos fadistas, que com o surgimento das novas formas de comunicação possibilitaram a sua interação com outras culturas e, consequentemente, com outras canções. Destaca-se em sua trajetória a transformação de música exclusivamente consumida pelos transgressores da lei e da moral à música representativa da cultura de um país, deixando para trás as casas de má fama do século XIX e ganhando espaço pelos palcos do mundo no século XXI. A indústria fonográfica e também o rádio constituem ferramentas que colaboraram para o desenvolvimento do fado. O objetivo desta dissertação é observar o fado na atualidade, recuperando sua história desde as origens no século XIX. Para isso identifica e localiza as diversas transformações ao longo do tempo e personagens que se destacaram durante este percurso, mostrando como as tradições são reinventadas pelas novas gerações que, em vários momentos, são responsáveis pelo zelo e, muitas vezes, pela reinvenção do fado como herança cultural. Nesta análise a globalização da cultura é considerada como um poder redefinidor do significado de uma tradição. Alguns fadistas serão os pontos de referência desta pesquisa, representativos de uma linha do tempo que se distribui em 200 anos de história. As letras de fado percorrerão esta pesquisa com o intuito de ilustrar os pontos abordados. Como pesquisa cartográfica apoiada no modelo dos rizomas proposto por Gilles Deleuze e Félix Guattari (2000), pretende-se analisar a história contemporânea do fado, tendo como marco temporal a Revolução dos Cravos decorrida em 25 de abril de 1974.

Nas águas da memória: o rio como metáfora em Dois irmãos e Órfãos do Eldorado, de Milton Hatoum

As narrativas Dois irmãos e Órfãos do Eldorado, de Milton Hatoum, estão cercadas pelo ambiente dos rios, espaço fluido, aquoso, profundo, que representa o limite entre a vida e a morte. O rio, cenário mítico, simbólico para o material ficcional das narrativas, metaforicamente também pode ser entendido como o lugar mais íntimo e profundo do ser, onde os personagens são levados a uma imersão, um voltar-se para si mesmo. Espaço de transcendência, permitida pelo mergulho na memória, que, assim como os rios, é dinâmica, instável, fluida. Temos nos livros de Hatoum narradores em primeira pessoa que se dedicam a recompor os fios dos tempos através de relatos, num processo solitário, por vias da memória. Eles fazem um mergulho no íntimo do homem e descobrem sua condição humana, frágil. Num trabalho de catarse e de autorreflexão, alimentado pela memória, eles se descobrem estranhos a si mesmos, uma vez que, ao reconstruir a própria história, o sujeito está calcado no momento presente. O eixo temporal da narração é, desse modo, presente-passado. Nesse sentido, há importância em compreendermos que a memorização exige estratégias. Os contos, os ritos, os mitos, as fábulas fazem parte desse conjunto de estratégias, que, através de imagens e símbolos, transmitem, de geração em geração, a realidade de um povo, em tempo e espaço diferentes. É verdade que os narradores de Dois irmãos e Órfãos do Eldorado contam histórias particulares, mas eles o fazem se valendo dos elementos de que a memória individual e coletiva dispõem, memórias estas permeadas pelo ambiente em que estão inseridos. Entendemos, portanto, que estudar a memória é estudar a cultura e a história vivida de cada sujeito e de seus grupos. Quando se entende que a memória de um indivíduo é também a de sua região e dos grupos de que faz parte, considera-se o processo memorialístico como uma construção coletiva. Isso significa que a memória individual é parte da memória coletiva. Desse modo, nos textos estudados, é pelo viés da memória que se entrelaçam espaços e tempos num lugar em que o rio se coloca entre os mundos narrados
