RESUMO

A citizen-centric view is key to channeling technological affordances into the development of future cities in which improvements are made with the quality of citizens' life in mind. This paper proposes City 5.0 as a new citizen-centric design paradigm for future cities, in which cities can be seen as markets connecting service providers with citizens as consumers. City 5.0 is dedicated to eliminating restrictions that citizens face when utilizing city services. Our design paradigm focuses on smart consumption and extends the technology-centric concept of smart city with a stronger view on citizens' roadblocks to service usage. Through a series of design workshops, we conceptualized the City 5.0 paradigm and formalized it in a semi-formal model. The applicability of the model is demonstrated using the case of a telemedical service offered by a Spanish public healthcare service provider. The usefulness of the model is validated by qualitative interviews with public organizations involved in the development of technology-based city solutions. Our contribution lies in the advancement of citizen-centric analysis and the development of city solutions for both academic and professional communities.

RESUMO

The Patagonian steppe is a refuge for several indigenous peoples who live in relatively isolated communities, depending heavily on natural resources for their activities, health, and food security. The local ecological knowledge is a reservoir that generates full wellbeing and for which it must be the object of protection and local development. In this study, we aimed to find which factors can influence local ecological knowledge from a metacommunity on the Patagonian steppe. We analyzed variation in knowledge about cultivated and gathered plants used as medicinal, edible, and firewood according to multiple factors widely discussed in the ethnobiological literature: age, gender, formal education, occupation, indigenous identity, contact with urban centers, use of biomedicine, hunting, and handcrafted textile production. We conducted semi-structured interviews with local experts, accessed by the snowball technique. We found that formal education is a key factor in the variation of local ecological knowledge among people. In addition, we found that knowledge varies between people who practice activities inside and outside the home, concentrating knowledge between cultivated and gathered plants, respectively. Our urbanization proxies did not point to an influence of this factor on local knowledge, but specialists living in a larger community with signs of internal urbanization processes had much less knowledge. Our results allowed us to visualize the importance of studying metacommunities as a whole, to verify complexities and intersections of overlapping factors. Studies in metacommunities open up a range of possibilities for ethnobiological analysis.

RESUMO

BACKGROUND: We aimed to verify whether the taste and chemical composition influence the selection of plants in each medicinal category, whether within a socio-ecological system or between different socio-ecological systems. To this end, we use the theoretical bases of the Utilitarian Redundancy Model and the Utilitarian Equivalence Model. We studied the local medical systems of four rural communities in northeastern Brazil, used as models to test our assumptions. METHODS: The data on medicinal plants and local therapeutic function were obtained from semi-structured interviews associated with the free-listing method, allowing to generate indexes of similarity of therapeutic use between the plants cited in each region. During the interviews, each informer was also asked to report the tastes of the plants cited. Subsequently, we classified each plant in each region according to the most cited taste. The data about the chemical composition of each plant were obtained from a systematic review, using Web of Knowledge and Scopus databases. RESULTS: Pairs of plants with similar tastes are 1.46 times more likely to have the same therapeutic function within a local medical system (redundancy), but not between medical systems (equivalence). We also find that chemical compounds are not primarily responsible for utilitarian redundancy and equivalence. However, there was a tendency for alkaloids to be doubly present with greater expressiveness in pairs of equivalent plants. CONCLUSIONS: The results indicate that each social group can create its means of using the organoleptic characteristics as clues to select new species as medicinal. Furthermore, this study corroborates the main prediction of the Utilitarian Equivalence Model, that people in different environments choose plants with traits in common for the same functions.

RESUMO

Most of the studies with a focus on pathways and biases of cultural transmission in different domains show that vertical transmission predominates over horizontal and oblique transmission, especially in traits linked to traditions and survival skills, such as local medicine. However, overestimation of the importance of vertical transmission has been an object of methodological criticism. Therefore, a statistical analysis with diachronic perspective may obtain more accurate results. The present study uses an eight-year time frame, as well as synchronous analysis, to study evolutionary aspects that guide the transmission pathways of a local medical system in northeast Brazil. We find that even with vertical transmission being predominant in the learning of information in this cultural domain, the evolutionary implications of this predominance may not be the same as that expected by the theory of cultural evolution. There is a substantial updating of knowledge through horizontal and oblique routes, guided primarily by a model-based bias on prestige and success, which is quite adaptive. Moreover, even when the information is passed vertically, the transmission is much more diffusive than conservative. Indeed, there is a small set of information that remains over time, known as a "structural core," but new information is aggregated continuously, preparing the system to adapt to new events. By analyzing the transmission routes of knowledge about medicinal plants, this study presents a new perspective on the evolutionary implications of cultural transmission.

RESUMO

Ethnobotanical studies focused on understanding how local medical systems are functionally maintained suggest that utilitarian redundancy and knowledge transmission are factors that influence the resilience of the system. However, to date, there have not been any studies that analyze these factors in relation to the variables that influence the variation of knowledge. Given the above, this study aims to analyze the influence of gender in the resilience of the system, using utilitarian redundancy and knowledge transmission as factors. Information from 198 married couples (396 people) was collected from the indigenous community of Fulni-ô (NE Brazil). Knowledge between men and women was analyzed based on the total number of known plants, therapeutic targets, information units, utilitarian redundancy, models of transmission, and sharing for each gender. Fulni-ô men know a greater number of plants, therapeutic targets treated with plants, and information units than women. They also had greater utilitarian redundancy. However, regarding knowledge transmission, sharing among women was greater, transmission is related to gender, and there is no difference between the numbers of models of knowledge information. In the system of local medical knowledge, gender exerts an important role in the resilience of the system. This study shows that men have a greater contribution to the structure and function of the system; however, both genders contribute to the flow of information in the system, which makes both genders important in the feedback of information.

RESUMO

The interest in theoretical frameworks that improve our understanding of social-ecological systems is growing within the field of ethnobiology. Several evolutionary questions may underlie the relationships between people and the natural resources that are investigated in this field. A new branch of research, known as evolutionary ethnobiology (EE), focuses on these questions and has recently been formally conceptualized. The field of cultural evolution (CE) has significantly contributed to the development of this new field, and it has introduced the Darwinian concepts of variation, competition, and heredity to studies that focus on the dynamics of local knowledge. In this article, we introduce CE as an important theoretical framework for evolutionary ethnobiological research. We present the basic concepts and assumptions of CE, along with the adjustments that are necessary for its application in EE. We discuss different ethnobiological studies in the context of this new framework and the new opportunities for research that exist in this area. We also propose a dialog that includes our findings in the context of cultural evolution.

RESUMO

ETHNOPHARMACOLOGICAL RELEVANCE: The study of plant use in contexts of migrations can give important insights to cultural evolution, since people face rapid changes in their environments and often start interacting with native dwellers, both constituting forces that can lead to change. Therefore, this study focused on medicinal plant knowledge and transmission in order to understand what happens to such knowledge when people from several regions converge to a single place already inhabited by native people. METHODS: The study was carried out in the rural community of Caeté-Açu (known as Capão Valley), placed in the state of Bahia (NE Brazil). Native and migrant people's knowledge on medicinal plans was accessed with a free listing. People were also asked about whom in the community once taught them about medicinal plants. Four groups (native, regional migrants, national migrants and international migrants) were compared in terms of number of cited plants, plant repertoires and knowledge transmission. For each group we also ran simple regressions between age and number of cited plants and residence time and number of cited plants. RESULTS AND DISCUSSION: We found no differences among groups in terms of number of known species. However, plant repertoires differ in some extent among groups. While migrants claim to have learnt with both native people and other migrants, most native claim to have learned mainly with other natives. Age influences plant knowledge only for the natives, what strengthens evidence that this group's knowledge is based on experience while migrants'' knowledge is based on an active search. Residence time in the community did not influence migrants' knowledge. CONCLUSION: Native and migrant people have differences in their ways of acquiring medicinal plant knowledge and less popular species are also different between groups. However, we can observe a tendency of fusion and indissolubility of migrant and native knowledge since the new generations are in contact with both sources.

RESUMO

Resilience is related to the ability of a system to adjust to disturbances. The Utilitarian Redundancy Model has emerged as a tool for investigating the resilience of local medical systems. The model determines the use of species richness for the same therapeutic function as a facilitator of the maintenance of these systems. However, predictions generated from this model have not yet been tested, and a lack of variables exists for deeper analyses of resilience. This study aims to address gaps in the Utilitarian Redundancy Model and to investigate the resilience of two medical systems in the Brazilian semi-arid zone. As a local illness is not always perceived in the same way that biomedicine recognizes, the term "therapeutic targets" is used for perceived illnesses. Semi-structured interviews with local experts were conducted using the free-listing technique to collect data on known medicinal plants, usage preferences, use of redundant species, characteristics of therapeutic targets, and the perceived severity for each target. Additionally, participatory workshops were conducted to determine the frequency of targets. The medical systems showed high species richness but low levels of species redundancy. However, if redundancy was present, it was the primary factor responsible for the maintenance of system functions. Species richness was positively associated with therapeutic target frequencies and negatively related to target severity. Moreover, information about redundant species seems to be largely idiosyncratic; this finding raises questions about the importance of redundancy for resilience. We stress the Utilitarian Redundancy Model as an interesting tool to be used in studies of resilience, but we emphasize that it must consider the distribution of redundancy in terms of the treatment of important illnesses and the sharing of information. This study has identified aspects of the higher and lower vulnerabilities of medical systems, adding variables that should be considered along with richness and redundancy.

RESUMO

Medicinal plants are an important aspect of local medical systems. The composition of a medicinal plant collection is influenced by cultural and environmental factors. Additionally, the functionality of a local medical system can be threatened by the replacement of native species with exotic ones, as well as by cultural factors such as the erosion of knowledge. The objectives of this study are: 1) examine the composition of the medicinal plant collection of two rural communities settled in the caatinga (savanna-like vegetation) of the state of Pernambuco (Brazil); 2) observe the role of exotic plants in the local medical systems; and 3) identify the profile of the species utilized according to the Utilitarian Redundancy Model. Similarities were observed between the medicinal floras of the communities studied, emphasizing the importance of the surrounding biome within the possibilities of species selection, although exotic species appear to contribute by increasing the diversity of species considered in the communities to be medicinal. The native species act broadly among the body systems recognized in the two communities, whereas exotic species act in specific body systems, for which there are few associated native species.

RESUMO

As armas de fogo são largamente utilizadas para a prática de homicídios, suicídios e lesões corporais. Utilizadas pelas forças policiais em todo o mundo, provocam lesões caracterizadas por extensa destruição tecidual, cujo tratamento é complexo e requer, muitas vezes, grandes reconstruções. Na tentativa de controlar situações de agitação social, manifestações, tumultos ou depredações sem, contudo, matar ou ferir gravemente os participantes, a polícia vem utilizando armas de munição não letal. embora não letal, se a munição atingir partes delicadas do corpo, pode causar danos importantes ou, até mesmo, levar à morte da vítima. O objetivo deste trabalho foi relatar um caso clínico de um paciente atendido no Serviço de emergência do Hospital Municipal Salgado Filho/RJ-Brasil, vítima de fratura de mandíbula, em decorrência de uma agressão por projétil não letal bem como discutir a capacidade de morbidade dessas munições que, embora consideradas não letais, se incorretamente utilizadas, podem levar ao óbito.


Firearms are widely used for the practice of homicides, suicides and injuries. Used by police forces around the world, causing lesions characterized by extensive tissue destruction, whose treatment is complex and often requires, large reconstructions. In an attempt to control situations of social unrest, demonstrations, riots or vandalism without, however, kill or seriously injure the participants, the police have been using non-lethal weapons ammunition. While not lethal, if the ammunition reaches delicate parts of the body can cause serious damage or even lead to death of the victim. The aim of this study was to report a case of a patient treated at the emergency Service of the Salgado Filho Municipal Hospital / RJ-Brazil, victim of mandible fracture as a result of an assault by non-lethal projectile, as well as discuss the ability of morbidity this ammunition that, while considered non-lethal, if used incorrectly, can lead to death.

RESUMO

A penetração de corpos estranhos na cavidade orbitária normalmente ocorre pelo trauma direto e penetrante. A depender da localização e da composição do corpo estranho, o diagnóstico pode ser feito por observação direta ou mediante exames de imagens. As radiografias convencionais, as ultrassonografias, as tomografias computadorizadas e a ressonância magnética são exames auxiliares no diagnóstico. Entretanto, a natureza de alguns corpos estranhos pode dificultar a sua identificação a despeito dos exames de imagem utilizados. A presença de corpos estranhos na cavidade orbitária pode resultar em celulites orbitárias, lesões oculares, lesões cutâneas adjacentes, amaurose, perda parcial da acuidade visual, entre outras complicações. O objetivo deste trabalho foi relatar um caso clínico de uma paciente, 17 anos de idade, feoderma, agredida com um pedaço de madeira, diretamente sobre a órbita esquerda. A paciente evoluiu com celulite orbitária refratária à antibioticoterapia e perda da acuidade visual do olho esquerdo. A radiografia de face não revelou a presença de corpos estranhos. Na tomografia computadorizada das cavidades orbitárias, observou-se, na órbita esquerda, imagens com densidade semelhante a ar. A paciente foi, então, submetida à cirurgia exploratória, sob anestesia geral, no Hospital Municipal Miguel Couto /RJ, e nela inúmeros fragmentos de madeira foram removidos, evoluindo com remissão do processo infeccioso.


The intrusion of foreign bodies into the orbital cavity usually occurs through direct and penetrating trauma. Depending on the location and composition of the foreign body, the diagnosis can be made by direct observation or by the analysis of imaging studies. Conventional radiography, ultrasound, CAT scans and MRI are used as auxiliary investigations in the diagnosis. However, the nature of some foreign bodies can make their identification difficult, even with the use of imaging techniques. The presence of foreign bodies in the orbital cavity may result in orbital cellulitis, eye lesions, adjacent skin lesions, blindness, partial loss of visual acuity, among other complications. The aim of this study was to report the clinical case of a female dark-skinned patient, aged 17, injured by a piece of wood directly onto her left orbit. The patient developed orbital cellulitis, which was unresponsive to conventional antibiotic therapy, and loss of visual acuity. Radiography of the face did not reveal the retention of any foreign bodies. Computed tomography of the orbital cavity revealed images with a density similar to that of air were observed. The patient underwent exploratory surgery under general anesthesia at Hospital Miguel Couto - RJ, resulting in the removal of many wood fragments from the orbital cavity and the resulting remission of the infectious process.
