Introduction

Worldwide, 2.4 billion people rely on solid fuels such as wood or charcoal for cooking, leading to approximately 3.2 million deaths per year from illnesses attributable to household air pollution. Across Africa, household air pollution generated by solid fuel use accounts for nearly 700,000 deaths each year. Most studies to date have focused either household air pollution exposure, its impacts on particular health outcomes or on the efficacy of mitigation interventions. However, the economic, social, and cultural determinants of household air pollution in Africa are still poorly understood. The purpose of this study was to explore people’s experience of using solid fuels for cooking in two informal settlements, Ndirande in Malawi and Mukuru in Kenya, and the associated harms caused by household air pollution.

Methods

We adopted a community-based participatory method, photovoice, which was conducted with 9 participants in Ndirande and 10 participants in Mukuru. Participants took pictures reflecting their experiences and perceptions of household air pollution harms over a two-week period, and later discussed, sorted and analysed those in a series of meetings. Thematic analysis was used to analyse the data.

Results

With their pictures, participants described fuel stacking and switching behaviours in their communities. They described a mix of charcoal, firewood and other biomass fuels use. They also expressed their awareness and perceptions of the harms caused by smoke when cooking. Participants explained the simple behaviours used by residents to minimize the harms of household air pollution to themselves and within their own household. Other themes explored the roles and responsibilities for procuring fuels in the home, and the stated solutions required to address the issues and manage the transition to cleaner fuels in those informal settlements.

Conclusion

This study highlights not only the need to understand the daily life, priorities and concerns of those who use solid fuels on informal settlements, but also the urgency to place them and their experience at the heart of the solutions that will reduce the health harms of household air pollution.

Background

Despite declining COVID-19 incidence, healthcare workers (HCWs) still face an elevated risk of Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) infection. We developed a diagnostic multivariate model to predict positive reverse transcription polymerase chain reaction (RT-PCR) results in HCWs with suspected SARS-CoV-2 infection.

Methods

We conducted a cross-sectional study on episodes involving suspected SARS-CoV-2 symptoms or close contact among HCWs in Bogotá, Colombia. Potential predictors were chosen based on clinical relevance, expert knowledge, and literature review. Logistic regression was used, and the best model was selected by evaluating model fit with Akaike Information Criterion (AIC), deviance, and maximum likelihood.

Results

The study included 2498 episodes occurring between March 6, 2020, to February 2, 2022. The selected variables were age, socioeconomic status, occupation, service, symptoms (fever, cough, fatigue/weakness, diarrhea, anosmia or dysgeusia), asthma, history of SARS-CoV-2, vaccination status, and population-level RT-PCR positivity. The model achieved an AUC of 0.79 (95% CI 0.77–0.81), with 93% specificity, 36% sensitivity, and satisfactory calibration.

Conclusions

We present an innovative diagnostic prediction model that as a special feature includes a variable that represents SARS-CoV-2 epidemiological situation. Given its performance, we suggest using the model differently based on the level of viral circulation in the population. In low SARS-CoV-2 circulation periods, the model could serve as a replacement diagnostic test to classify HCWs as infected or not, potentially reducing the need for RT-PCR. Conversely, in high viral circulation periods, the model could be used as a triage test due to its high specificity. If the model predicts a high probability of a positive RT-PCR result, the HCW may be considered infected, and no further testing is performed. If the model indicates a low probability, the HCW should undergo a COVID-19 test. In resource-limited settings, this model can help prioritize testing and reduce expenses.
Temporal habitat partitioning and resource competition between congenerics: Testing for density-dependent growth and mortality in estuarine shrimp

Habitat partitioning can promote coexistence of closely related competitors. Two congeneric shrimps (brown shrimp, Penaeus aztecus, and white shrimp, Penaeus setiferus) which utilize estuaries in the southeastern U.S. temporally partition much of their nursery habitat occupancy but also experience a period of overlap at the respective tails of their nursery residency. Throughout nursery residency, when conspecific or congeneric abundance can be high, density-dependent (D-D) processes may alter demographic rates, but the relative importance of the potential biotic interactions occurring in these habitats (e.g., intra- and inter-specific competition, cannibalism, among others) remains underexplored. Here, we documented the periods of nursery habitat use for these two penaeid shrimp species within a representative salt marsh estuary. Next, a set of manipulative laboratory experiments was conducted to test if conspecific or congeneric density, as well as the relative proportions of each species, affect growth and mortality. In three experiments designed to simulate each of the phases of penaeid shrimp nursery habitat use (brown only, brown and white overlap, white only), shrimp were maintained at ecologically relevant densities (12.5–37.5 m-2) and tagged to follow growth trajectories. We found varying degrees of density-dependence between species and across response variables (length, mass, mortality), with the effect of additional species identity varying between white and brown shrimp for all three response metrics. Body size was an important predictor of mortality for both brown and white shrimp, with smaller animals exhibiting higher mortality probabilities. These results suggest that changing environmental conditions could lead to D-D impacts on some demographic rates but not others for these ecologically and economically important species during their estuarine residency.
Novel method to investigate thermal exchange rates in small, terrestrial ectotherms: A proof-of-concept on the gecko Tarentola mauritanica

Thermoregulating ectotherms may resort to different external heat sources to modulate their body temperature through an array of behavioural and physiological adaptations which modulate heat exchange with the environment and its distribution across the animal’s body. Even small-bodied animals are capable of fine control over such rates and the subsequent re-allocation of heat across the body. Such thermal exchanges with the environment usually happen through two non-mutually exclusive modes: heliothermy (radiant heat gain from the sun) or thigmothermy (heat gained or lost via conduction). Classically, the study of these phenomena has relied on invasive methodologies which often disregard the effect of stress, behaviour and regional heterothermy on the rates and patterns of thermal exchange across the body of the animal. This study proposes a novel experimental methodology, capitalising on thermography, to provide an alternative method to less invasively obtain reliable body temperatures of thermoregulating ectotherms, while allowing behaviour and heating mode to be considered when quantifying thermal exchange rates. This methodology was tested in the gecko Tarentola mauritanica, where twenty males were allowed to heat up and cool down under a novel experimental set-up which isolates heliothermic and thigmothermic processes, while being recorded with a thermal camera. The study revealed differences in the heating and cooling rates of several body parts per treatment suggesting that thermal exchanges are complex even in small ectotherms. Ultimately, the described set-up provides the opportunity to revisit classical questions with a less invasive and more flexible experimental approach, enabling heliothermic and thigmothermic processes to be disentangled. The described methodology also better integrates behaviour and physiology while obtaining higher temporal and spatial resolution of body temperatures in a thermoregulating ectotherm.

The gastrointestinal tract is a prominent portal of entry for HIV-1 during sexual or perinatal transmission, as well as a major site of HIV-1 persistence and replication. Elucidation of underlying mechanisms of intestinal HIV-1 infection are thus needed for the advancement of HIV-1 curative therapies. Here, we present a human 2D intestinal immuno-organoid system to model HIV-1 disease that recapitulates tissue compartmentalization and epithelial-immune cellular interactions. Our data demonstrate that apical exposure of intestinal epithelium to HIV-1 results in viral internalization, with subsequent basolateral shedding of replication-competent viruses, in a manner that is impervious to antiretroviral treatment. Incorporation of subepithelial dendritic cells resulted in HIV-1 luminal sampling and amplification of residual viral replication of lab-adapted and transmitted-founder (T/F) HIV-1 variants. Markedly, intraepithelial viral capture ensued an altered distribution of specialized endosomal pathways alongside durable sequestration of infectious HIV-1 within lysobisphosphatidic acid (LPBA)-rich vesicles. Therapeutic neutralization of LBPA-dependent trafficking limited productive HIV-1 infection, and thereby demonstrated the pivotal role of intraepithelial multivesicular endosomes as niches for virulent HIV-1 within the intestinal mucosa. Our study showcases the application of primary human 2D immune-competent organoid cultures in uncovering mechanisms of intestinal HIV-1 disease as well as a platform for preclinical antiviral drug discovery.
The SpxA1-TenA toxin-antitoxin system regulates epigenetic variations of Streptococcus pneumoniae by targeting protein synthesis

Published: December 2024

Human pathogen Streptococcus pneumoniae forms multiple epigenetically and phenotypically distinct intra-populations by invertase PsrA-driven inversions of DNA methyltransferase hsdS genes in the colony opacity-determinant (cod) locus. As manifested by phase switch between opaque and transparent colonies, different genome methylation patterns or epigenomes confer pathogenesis-associated traits, but it is unknown how the pathogen controls the hsdS inversion orientations. Here, we report our finding of the SpxA1-TenA toxin-antitoxin (TA) system that regulates the orientations of hsdS inversions, and thereby bacterial epigenome and associated traits (e.g., colony opacity) by targeting pneumococcal protein synthesis. SpxA1 and TenA were found to constitute a highly conserved type II TA system in S. pneumoniae, primarily based on the observation that overexpressing toxin TenA led to growth arrest in E. coli and enhanced autolysis in S. pneumoniae, and the antitoxin SpxA1 repressed the transcription of the spxA1-tenA operon. When the transcription of tenA was de-repressed by a spontaneous AT di-nucleotide insertion/deletion in the promoter region of the spxA1-tenA operon, TenA bound to the ribosome maturation factor RimM, and thereby reduced the cellular level of alternative sigma factor ComX (known for the activation of natural transformation-associated genes). Attenuation of ComX expression in turn enhanced the transcription of the invertase gene psrA, which favored the formation of the transparent colony phase-associated hsdS allelic configurations in the cod locus. Phenotypically, moderate expression of TenA dramatically reshaped pneumococcal epigenome and colony opacity. Because spontaneous variations frequently occur during bacterial growth in the number of the AT di-nucleotides in the promoter region of the spxA1-tenA operon, this locus acts as a programmed genetic switch that generates pneumococcal subpopulations with epigenetic and phenotypic diversity.

Queer counterpublic and queer fan activism in South Korean K-Pop fandom: A case study of ‘Rainbow MooMoo’
Authors: George Olivia
Published: December 2024

From 2017 to 2019, queer K-Pop fan organizations rapidly surfaced in Korean Twitter fandom. This article explores one such project, mujigae mumu (‘Rainbow MooMoo’), an organization of queer fans of the popular girl group Mamamoo (2014–present). Rainbow MooMoo’s project exemplifies recent scholarship on K-Pop fandom’s liberatory and political potentials, particularly those emerging from case studies in global and anglophone K-Pop fandom spaces. However, the mobilization of queer fans in South Korean K-Pop fandom prompts us to revisit and reinterpret K-Pop fandom as a subversive and political space in non-western contexts. Through a case study of Rainbow MooMoo, I highlight K-Pop fandom’s domestic political role by examining how queer fan activist organizations like Rainbow MooMoo act as a site for fans to find queer belonging and connect to a broader queer counterpublic network, facilitating K-Pop fans’ flow between private consumption and public political participation. In doing so, I also underscore how Korean fans’ positionality vis-à-vis K-Pop as a heteronormative and mainstream cultural mode uniquely shapes and limits fans’ political activities and expressions.
Exploring Philippine queer possibilities through transformative K-pop imaginations online
Authors: Santos Kristine Michelle L.
Published: December 2024

Given its accessibility in the last decade, K-pop has become one of the strong cultural forces in Philippine youth media that has heavily influenced the consumption practices of local fans. From collecting photo cards to organizing cupsleeve events, Filipino K-pop fans have embraced and adapted different fan practices, some of which are intimately queer. One such queer fan practice is ‘K-pop shipping’ where fans imagine their favourite idols engaging in romantic, and sometimes sexual, relationships within and outside of their groups. Beyond embracing queer literacies such as boys love, local K-pop shipping has grown intimately queer as Filipino fans developed stories that brought their idols closer to home through a phenomenon termed ‘Filo AU’ (Filipino alternative universe). These Filo AUs are short-form fan narratives on social media that reimagine their favourite K-pop idols as locals who have Filipino backgrounds, live very Filipino experiences and values while finding queer romance. In this article, I examine queer K-pop Filo AU as a result of affective transnational queer literacies that inspire hope, connection and aspiration for queer utopias among Filipinos.
Netflix’s transnational identities: From Europeanness to cosmopolitanism in Sex Education
Authors: Liz Mariana
Published: December 2024

A British creation, Netflix’s original hit series Sex Education (2019–23) casually navigates local, national and global references. British and American protagonists appear from the first episode, joined by international characters from northern Europe and francophone Africa, although not much is made of these supposedly foreign identities. As much as the period in which the show is set cannot be easily pinpointed, since references to different temporal eras are screened in a vibrant mix of songs, patterns and colours, so does identity appear as fluid, constructed as a diffuse mix of accented languages, native idioms and cultural backgrounds. Aiming to unpack this apparently harmonious mix, this article focuses on Episode 5 of the third season, in which Eric travels to Nigeria with his family, while the remaining students go on a study trip to France. It asks what visions of hyphenated identities emerge, as well as what representations of Europe are put forward. From First World War trenches to romance, from toilet humour to rude French characters, the episode disparages ‘Europeanness’ and instead foregrounds the value of cosmopolitanism. It thus contributes to our understanding of the idea of Europe and its future, as framed by global audio-visual cultures.

Academic literacies in course proposals to EMI teacher education
Authors: Rodrigues Gabriel Salinet , Ribeiro Juliana Michelon , Hendges Graciela Rabuske
Published: December 2024

English as a Medium of Instruction (EMI) is a phenomenon of rapid expansion in Brazil and around the world (Dearden, 2015; Martinez, 2016) and has raised interest in a relevant share of professors at Universidade Federal de Santa Maria (Hendges; Rodrigues; Pretto, 2020). EMI has been pointed out as an alternative for Internationalization at Home (Beelen; Jones, 2015) and for the promotion of more accessible intercultural, international opportunities as it can also foster access to additional language learning in tertiary education (Baumvol; Sarmento, 2019). The particularities of a Brazilian public university call for a situated and critical-oriented practice, which is entailed in the Academic Literacies framework – ACLITS (Lillis, 1997; Lea; Street, 1998). In this work, we examine three syllabi of EMI courses designed for university faculty from the ACLITS perspective. Employing the approach of rich features analysis (Barton, 2004), we identified contents related to pedagogic and linguistic literacies and classified them according to approximations with the three models of literacy: Study Skills, Academic Socialization, and Academic Literacies. The emphasis on Academic Socialization in the syllabi suggests there is space for the development of local EMI teacher education initiatives that expand discussions about genre awareness, equity, translanguaging, interculturalism, and plurilingualism. These findings bring important insight for laboratories and departments that work with language (pre-service) educators and language support actions.
Pasando revista(s) a la música
Authors: Pínnola Fabián M.
Published: December 2024

A despecho de una aparente claridad sumaria, temática y epistémica que pareciera caracterizarla en cuanto a destinatarios, intereses, universos de circulación, la Revista del Instituto Superior de Música de la UNL (en adelante Revista del ISM) puede verse consignada en el enmarañado corpus heterogéneo de las «revistas sobre música». En efecto, en esta suerte de territorio multiforme, conviven publicaciones de diferente procedencia (académicas, institucionales–no académicas como teatros, independientes, vagamente asociadas a grupos de gestión cultural); por temáticas («géneros» musicales); por destinatario (cortes etarios, seguidores de —nuevamente— determinado «género» musical) y otros.
Acotando el enfoque encontramos que en el campo más restringido de las revistas académicas se pueden encontrar varias diferencias, tanto entre revistas como al interior de algunas de ellas. En efecto, unas se enfocan en exámenes de sesgo historicista, otras abrevan en recortes etnomusicológicos, otras, en fin, hacen de la didáctica su punto central. En este panorama, la Revista del ISM, transitando 35 años de existencia, nos permite observar ciertos aspectos de su construcción discursiva y de lo relacionado con sus contenidos.
¿Qué temas aparecieron y aparecen en sus índices? ¿Existen constantes en los sumarios presentes a lo largo de su historia? ¿Sobre qué y cómo «se habla» en nuestra revista? ¿Es posible «leer» algunas contingencias históricas, epocales, coyunturales, en sus números?
A través del relevamiento de diferentes números de la Revista del ISM, este trabajo propone una lectura sobre los enfoques y sentidos que los trabajos de autorxs fueron y van construyendo, a guisa de una identidad siempre en movimiento, en progreso, en discusión.
ENSEMBLE-BASED LOGISTIC REGRESSION ON HIGH-DIMENSIONAL DATA: A SIMULATION STUDY
Authors: Widhianingsih Tintrim Dwi Ary , Kuswanto Heri , Prastyo Dedy Dwi
Published: December 2024

Dramatic computation growth encourages big data era, which induces data size escalation in various fields. Apart from huge sample size, cases arise high-dimensional data having more feature size than its samples. High-computing power compels the usage of modern approaches to deal with this typical dataset, while in practice, common logistic regression method is yet applied due to its simplicity and explainability. Applying logistic regression on high-dimensional data arises multicollinearity, overfitting, and computational complexity issues. Logistic Regression Ensemble (Lorens) and Ensemble Logistic Regression (ELR) are the logistic-regression-based alternative methods proposed to solve these problems. Lorens adopts ensemble concept with mutually exclusive feature partitions to form several subsets of data, while ELR involves feature selection in the algorithm by drawing part of features based on probability ranking value. This paper uncovers the effectiveness of Lorens and ELR applied to high-dimensional data classification through simulation study under three different scenarios, i.e., with feature size variation, for imbalanced high-dimensional data, and under multicollinearity conditions. Our simulation study reveals that ELR outperforms Lorens and obtains more stable performance over different feature sizes and imbalanced data settings. On the other hand, Lorens achieves more reliable performance than ELR on a simulation study with a multicollinearity issue.
IMPLEMENTATION OF PROPHET IN AMERICAN ELECTRICITY FORECASTING WITH AND WITHOUT PARAMETER TUNING

Published: December 2024

Prophet is one of the machine learning approximation methods that accommodate trends, seasonality, and holiday impacts in time series data. Generally, the performance of machine learning models can be improved by implementing hyperparameter tuning. This study investigates whether hyperparameter tuning can improve the model's performance. To show its effectiveness, the Prophet model constructed by parameter tuning is compared to the one with fixed parameter values (namely the default model) for both the original series and the Box-Cox transformed series in terms of mean absolute percentage error (MAPE). Based on the experimental results of the twenty-four daily electricity load time series in American Electric Power (AEP). This shows that parameter tuning successfully reduces the MAPE of the default model in the range of about 3-8% for training data. However, there is no guarantee for testing data. Although, in some cases, parameter tuning can reduce the MAPE value of the default model by up to 38%, in other cases, it actually increases the MAPE of the default model by almost 15%. The experiments on testing data also show that models built from transformed data do not necessarily produce more accurate forecast values than those built from the original data.
Primary trader preferences for participating in high-value markets in Black Pepper- A choice analysis

Published: December 2024

Facilitating the integration of primary traders into modern agricultural value chains, known as high-value markets (HVMs), presents a promising avenue for improving the sustainability of black pepper value chains in Kerala. Due to increased price volatility and risk exposure in trading conditions, primary traders are hesitant to prioritize quality aspects in their procurement decisions. A Best-Worst Scaling (BWS) experiment was employed with traders in the Agro-ecological units (AEUs) 12, 14, 15, 16, 17, 19, 20 and 21 of Kerala to comprehend their preferences regarding quality attributes that could promote sustained participation in HVMs. This study incorporates a unique aspect by examining the consistency of choices between the best and worst options, providing deeper insights into traders' decision-making processes and ensuring an accurate evaluation of preferences by minimizing biases. The choice experiment utilized fractional factorial and balanced incomplete block designs. The results indicate that traders predominantly favour a flexible, incentive-based pricing model and long-term formal relationships with buyers. Conversely, traders consistently rated premium payments and certification as the least favourable market attributes. Preference variations were influenced by traders' experience, income levels and location. The results reveal that primary traders possess the least understanding of factors that may facilitate their entry into HVMs. Our findings underscore the significance of educating traders on crucial market attributes that facilitate their participation in HVMs. Further research on their willingness to adapt to the requirements of HVMs to maximize the benefits to the system.

Authors: Liu Ziyu , Liu Yanqing , Zhang Chong , Sakamaki Takashi , Li Xianning
Published: December 2024

Conductive filter membranes have shown great potential in alleviating membrane fouling. In this study, polypyrrole (PPy) was used as the conductive material and sodium anthraquinone-2-sulfonate (AQS) was used as the dopant to perform surface modification on the PVDF membrane. After modification, the contact angle of the membrane decreased from 79.40° to 48.57°, and the electrical conductivity of membrane increased from zero to 1.60 S/cm. The good hydrophilicity and electrical conductivity of PPy-AQS/PVDF endowed it with superior antifouling capabilities, reducing the static protein (BSA) adsorption from 0.147 mg/cm2 to 0.097 mg/cm2. Under the action of an electric field of −0.1 V, the flux decay rate of PPy-AQS/PVDF decreased, and the flux recovery rate improved.

RESUMO: Os autores estudam uma amostra de cerâmica proveniente da Fazenda Luar do Sertão, no Chapadão dos Parecis, alta bacia do rio Juruena, MT. Depois de breve análise técnica da coleção, eles a contextualizam em termos de cultura e especulam a respeito do grupo étnico que a tenha produzido. A cerâmica é classificada como da tradição Uru, atribuída a grupos indígenas cultivadores de mandioca nos cerrados do Centro-Oeste Brasileiro. Um desses grupos, que deram o nome à região, são os Pareci, do tronco linguístico Arawak. A pequena amostra pode tornar-se útil como testemunho arqueológico para um espaço mal conhecido do Mato Grosso.ABSTRACT: The authors study a ceramic sample received from Fazenda Luar do Sertão, Chapadão dos Parecis, on the upper basin of Juruena river, MT. After a brief technical analysis, they contextualize the collection culturally and speculate about the ethnic group who produced the ware. The ceramic is classified in the Uru tradition, attributed to the native manioc cultivators of the tropical savanna of Midwestern Brazil. One of these populations, whose name identifies the region, is the Pareci, of the Arawak linguistic stock. The little ceramic sample may turn out to be useful as testimony to the occupation of a great insufficiently known space of Mato Grosso.
TODOS LOS FUEGOS EL FUEGO. Discusión en torno a las categorías modernas en la interpretación de registros antracológicos en contextos prehispánicos y coloniales

Resumen: En el presente texto discutimos los resultados de los análisis antracológicos de dos diferentes tipos de contexto recuperados en Argentina. Las ocupaciones coloniales e hispano indígenas de la ciudad de Mendoza iniciadas a mediados del siglo XVI, y del valle de Ambato, en el noroeste argentino, ocupado a lo largo del 1er milenio por grupos que la arqueología definió como Cultura Aguada. Ensayamos aquí un análisis que desplace la mirada de las plantas como meros recursos dialogando con algunas fuentes  etnográficas e históricas. Nos centramos particularmente en resultados “no esperables” en términos de lógicas que enfatizan sobre cuestiones economicistas o funcionales. Abstract: We discuss the results of the anthracological analysis of two different archaeological contexts in Argentina. The colonial occupation of Mendoza city started in the mid-sixteenth century, and the valley of Ambato in the northwest of the country, which was occupied during the 1st millennium by groups defined as Aguada Culture. We try here a dialogue with some ethnographic and historical sources to discuss the idea of plants as mere resources. We focus particularly on not expectable results in terms of logic that emphasize over economistic or functional issues.
OF FORESTS AND GARDENS: LANDSCAPE, ENVIRONMENT, AND CULTURAL CHOICES IN AMAZONIA, SOUTHEASTERN AND SOUTHERN BRAZIL FROM C. 3000 TO 300 CAL YRS BP
Authors: Scheel-Ybert Rita , Caromano Caroline Fernandes , Azevedo Leonardo Waisman de
Published: December 2024

Abstract: Brazilian rainforests have long been considered as pristine environments, ecologically representative of primary forest. Important discussions, arising especially from historical ecology, recognize that human populations significantly interfered in the vegetal landscape, but there were as yet any direct archaeological evidence. Anthracological analyses in sites of different cultural traditions from the Brazilian territory might provide such evidence. Examples driven from ceramist sites from Southeastern and Southern Brazil and from Amazonia demonstrate that these groups have transformed the forest landscape by creating areas of secondary vegetation and possible concentrating useful species. The secondary vegetation domesticated spaces surrounding the settlements were possibly preferred for firewood gathering due to its proximity, structure and/or social significance. It is noteworthy that anthropogenic disturbance, clearing, and creation of secondary environments do not result in irreversible damage to local biodiversity, due to the resilience of natural ecosystems and their hability of regeneration. We conclude interpreting the data according to the premise that reconstructing landscape in archaeological sites implies to overcome merely economistic or naturalistic interpretations and understand the underlying cultural determinants to the data, without neglecting their ecological significance. Resumo: As florestas ombrófilas do Brasil foram durante muito tempo consideradas como ambientes intocados pela ação humana e ecologicamente representativos de florestas primárias. Mais recentemente, importantes discussões, surgidas especialmente no quadro da ecologia histórica, passaram a reconhecer que populações humanas interferiram significativamente na paisagem, mas não existiam até o momento evidências arqueológicas diretas. Análises antracológicas em sítios de diferentes tradições culturais que ocuparam o território brasileiro vêm oferecendo tais evidências. Exemplos obtidos em sítios ceramistas do Sudeste e do Sul do país e na Amazônia demonstram que a ocupação humana alterou a vegetação local criando ambientes antropogênicos. Os diferentes grupos estudados transformaram a paisagem com a criação de áreas de vegetação secundária e uma possível concentração de espécies úteis. Devido à sua proximidade, estrutura e/ou significado social, os espaços de vegetação secundária domesticada no entorno dos assentamentos eram possivelmente preferidos para a coleta de lenha. Conclui-se interpretando os dados de acordo com a premissa de que estudar paisagem em sítios arqueológicos implica em, sem negligenciar os significantes ecológicos, ultrapassar interpretações meramente economicistas ou naturalistas e perceber os determinantes culturais subjacentes aos dados.

Resumo: O desenvolvimento de abordagens socioeconômicos aplicadas à antracologia permitiu abordar temas relacionados com a utilização e gestão da lenha. Estudos etnográficos nos lembram que os critérios segundo os quais uma sociedade escolhe sua lenha não podem ser reduzidos a uma seleção taxonômica "simples": outras características, tais como o diâmetro ou o estado da madeira (verde, seco, podre) são pelo menos tão importante quanto a espécie. Este artigo apresenta uma síntese das recentes ferramentas desenvolvidas para aumentar o potencial da antracologia para o estudo dos usos e gestão de lenha. Experimentos de laboratório padronizados sobre amostras de pinheiro silvestre (Pinus sylvestris), combinando forno mufla e combustões em lareira aberta, permitiram propor novos métodos para identificar o diâmetro e o estado da madeira com base em assinaturas anatômicas. Graças a estes métodos, é possível contribuir para um melhor conhecimento das tradições técnicas ligadas ao uso do fogo, desde a coleta de madeira até fogueiras especializadas, a partir de amostras de carvão arqueológicas.Abstract: The development of socioeconomic approaches applied to charcoal analysis has made it possible to focus on topics related to firewood use and management. Ethnographic studies remind us that the criteria according to which a society chooses its firewood cannot be reduced to a “simple” taxonomic selection: other characteristics, such as the diameter or the state of the wood (i.e. green, seasoned, rotten) are at least as important as the species. The framework of this paper is to present a synthesis of recent tools developed to improve the potential of charcoal analysis for the study of firewood uses and management. Standardized laboratory experiments on Scot Pine (Pinus sylvestris) combining both muffle furnace and open fireplace combustions allowed proposing new methods of identifying the diameter and the state of the wood based on anatomical signatures. Thanks to these methods, it becomes possible to contribute to a better knowledge of the technical traditions linked to the use of fire, from wood gathering to specialized hearths on archaeological charcoal samples.

RESUMO: O artigo apresenta os resultados preliminares do projeto “A Utilização de Plantas pelos Guarani no Bioma Mata Atlântica da Planície Costeira do litoral sul do Estado de Santa Catarina, Brasil”. O objetivo foi levantar em fontes históricas e etnográficas as plantas utilizadas, sempre que possível identificando o nome Guarani, a espécie e sistematizando quais as partes utilizadas. Foram registradas em quatro fontes 639 espécies botânicas de 109 famílias (incluindo 28 espécies não identificadas). Myrtaceae, Fabaceae, Asteraceae, Lauraceae e Poaceae foram, respectivamente, as famílias mais importantes em quantidade de espécies. As partes mais utilizadas foram fruto, caule e folhas. A maior porcentagem de utilização está relacionada aos usos alimentares, medicinal e matéria-prima, respectivamente. Nossos resultados sugerem uma estreita interação entre os Guarani e a Mata Atlântica, com fortes evidências de que o seu modelo de manejo agroflorestal foi intensamente aplicado na área por mais de 500 anos.ABSTRACT: This article presents preliminary results of the project "The plants used by the Guarani in the Atlantic Forest Biome of the South Coast of the Santa Catarina State, Brazil." The goal is the survey of historical and ethnographic sources on the plants used by the Guarani, identifying name, species and systematize the parts used. We recorded 639 plant species of 109 families, raised on four sources (including 28 species not identified). Myrtaceae, Fabaceae, Asteraceae, and Lauraceae Poaceae were respectively the most important families in number of species. The most used parts were fruit, stems and leaves. The highest percentage of use is related to human consumption, medicinal and raw materials respectively. Our results suggest a close interaction between the Guarani and the Atlantic Forest, with strong evidence that its agroforestry model has been extensively applied in the area for over 500 years.
A FAZENDA CAMAPUÃ

RESUMO: A Fazenda Camapuã constituiu-se no primeiro núcleo português permanente de Mato Grosso do Sul, tornando-se frente de povoamento extremamente importante em uma colônia em que as fronteiras eram móveis e provisórias. Entreposto de abastecimento aos monçoeiros que se dirigiam às minas de ouro de Cuiabá, com produção regular de gêneros agrícolas e de animais para abate, também cumpriu papel importante dentro da política de expansão portuguesa no sentido de reforçar a submissão e exploração dos povos autóctones, sobretudo os caiapós, legítimos habitantes destes territórios.ABSTRACT:  The Farm Camapuã constituted the first permanent Portuguese core of Mato Grosso do Sul, became front line of settlements and extremely important for a colony whose borders were transitory and moving. As a supplier for monçoeiros who addressed to the Gold mines in Cuiabá, and producer of agricultural genres and slaughter animals, also played an important role in the Portuguese expansion policy in order to reinforce the submission and exploitation of the native people, especially the Caiapós people, legitimate inhabitants of those territories.

RESUMO: Este trabalho apresenta uma síntese conceitual e de aplicação de como aspectos relevantes em Meio Ambiente Cultural são abordados em empreendimentos de mega-escala, conciliando desenvolvimento tecnológico contemporâneo com a preservação e valorização da identidade cultural. Dividimos o texto em três partes: i) Arqueologia e Preservação sob a ótica dos desafios globais; ii) Modelos Preditivos em Arqueologia; iii) Identidade Cultural e Inteligência Coletiva. Este texto foi originalmente elaborado no formato de um working paper, integrado à prática dos profissionais do Grupo DOCUMENTO em realizar pesquisas e aprofundar temas científicos e sociais demandados pelos seus projetos de pesquisa. Foi, agora, atualizado para o formato de artigo, apresentando reflexões no bojo da elaboração de um modelo consolidado de Gestão do Conhecimento, em que a ciência expande seu potencial quando ferramentas de inteligência coletiva são implementadas e se mostram capazes de ampliar o significado e as oportunidades junto ao patrimônio cultural abarcado.ABSTRACT: This article introduces a conceptual synthesis and its application to Cultural Environment into mega-scale projects. It conciliates current technological development with cultural identity preservation and its sustainable valuation. For better explanation, this article is divided in three major bodies of application: i) Archaeology of Preservation from the perspective of global challenges; ii) Applied Predictive Models in Archaeology; iii) Cultural Identity and Collective Intelligence. Such article was originally elaborated as a working paper integrated to the practice of the Scientific Committee of Documento during several projects in which scientific and social symmetry is highly required for the cultural risk management. Once a model was built into a solid ecosystem, we decided to introduce our model for knowledge management along with its tools for adaptive management, collective intelligence and risk management.

The full complement of ion channels which influence insect auditory mechanotransduction and the mechanisms by which their influence is exerted remain unclear.Shal(Kv4), aShakerfamily member encoding voltage-gated potassium channels inDrosophila melanogaster, has been shown to localize to dendrites in some neuron types, suggesting the potential role ofShalinDrosophilahearing, including mechanotransduction. A GFP trap was used to visualize the localization of theShalchannel in Johnston's organ neurons responsible for hearing in the antenna.Shalprotein was localized strongly to the cell body and inner dendritic segment of sensory neurons. It was also detectable in the sensory cilium, suggesting its involvement not only in general auditory function but specifically in mechanotransduction. Electrophysiological recordings to assess neural responses to auditory stimuli in mutantShalflies revealed significant decreases in auditory responses. Laser Doppler vibrometer recordings indicated abnormal antennal free fluctuation frequencies in mutant lines, indicating an effect on active antennal tuning, and thus active transduction mechanisms. This suggests thatShalparticipates in coordinating energy-dependent antennal movements inDrosophilathat are essential for tuning the antenna to courtship song frequencies.
