Multilevel processes and cultural adaptation: examples from past and present small-scale societies

The last two decades have seen a proliferation of research frameworks that emphasise the importance of understanding adaptive processes that happen at different levels. We contribute to this growing body of literature by exploring how cultural (mal)adaptive dynamics relate to multilevel social-ecological processes occurring at different scales, where the lower levels combine into new units with new organizations, functions, and emergent properties or collective behaviors. After a brief review of the concept of “cultural adaptation” from the perspective of cultural evolutionary theory, the core of the paper is constructed around the exploration of multilevel processes occurring at the temporal, spatial, social, and political scales. We do so by using insights from cultural evolutionary theory and by examining small-scale societies as case studies. In each section, we discuss the importance of the selected scale for understanding cultural adaptation and then present an example that illustrates how multilevel processes in the selected scale help explain observed patterns in the cultural adaptive process. The last section of the paper discusses the potential of modeling and computer simulation for studying multilevel processes in cultural adaptation. We conclude by highlighting how elements from cultural evolutionary theory might enrich the multilevel process discussion in resilience theory.

Narrativa histórica: El legado de la novela Yo, El Supremo de Augusto Roa Bastos en la consolidación de la identidad cultural del Paraguay

La novela Yo, el Supremo del escritor paraguayo Augusto Roa Bastos* se basa en una figura histórica controversial y en los acontecimientos que rodearon a ese personaje. Aunque conocer los hechos más trascendentes de esa época no es indispensable para comprender el texto de la obra, la referencialidad histórica juega un papel importante en la narrativa del Supremo, pues en el proceso de desarrollo argumental de la obra él se nutre de ella para expresar ciertas ideas relacionadas, entre otras, con el concepto comunitario paraguayo. El personaje se mueve dentro de una macro-temporalidad. No obstante, hay una sistemática referencia a una época determinada que sobresale en su discurso. La referencialidad histórica está así funcionando como un marcador temporal y, al mismo tiempo, señala que el discurso de el Supremo es portador de ciertos valores correspondientes a esa época. Los conceptos socio-políticos que maneja el personaje no son abstractos sino que se identifican con el ser paraguayo del siglo XIX.AbstractThe novel Yo, el Supremo, by Paraguayan writer Augusto Roa Bastos, is based on a historical and controversial character and on the facts that surrounded this character. Even though it is not important to know the most important events of that time to understand the text, the historical references play an important role in the narrative of the Supremo because in the process of the argumentative development he is nourished from those references in order to express some ideas related, among others, with the communal Paraguayan concept. The character moves inside a macro-temporal level. However, there is systematic reference to a specific epoch that is highlighted in his discourse. The historical references thus works as a temporal marker and, at the same time, reveals that the discourse of the Supremo contains some values that correspond to that time. The socio-political concepts that the character works with are not abstract but rather show the Paraguayan identity of the XX century.

Quotidianos d(n)a Internacionalização: Mobilidade Universitária, TIC e Vida Pessoal à Distância

Neste texto sintetizam-se os principais resultados de um projeto de iniciação à investigação científica, desenhado com o objetivo de descrever e compreender o lugar das tecnologias da informação e comunicação na construção da vida pessoal à distância de estudantes, professores e investigadores em situação de mobilidade universitária internacional. Os dados analisados foram recolhidos a partir de um questionário eletrónico, aplicado em Dezembro de 2013 na Universidade de Évora, orientado para a recolha de informação em cinco dimensões principais: a caracterização sociodemográfica dos indivíduos em situação de mobilidade universitária internacional, o perfil de mobilidade, os sentidos da casa, os contextos de comunicação à distância e, por fim, os propósitos, conteúdos e significados associados a tais práticas. No final, ao mesmo tempo que os dados trazidos a lume permitem uma caracterização ampla, plural e actual da experiência dos indivíduos em mobilidade internacional, abrem espaço para uma discussão e reflexão crítica em torno do lugar da internacionalização nas instituições de ensino superior, regiões e contextos em que estão inseridas, tanto do ponto de vista educacional, como cultural.

High temporal resolution insights into early life histories: integrating histomorphometric, trace element and isotopic analyses of dental hard tissues in archaeological populations from Italy

Teeth, with their high mineralisation, incremental growth, and lack of remodelling, serve as biological archives that document an individual's development. This project aims to utilise the potential of teeth in bioarchaeological studies to achieve three primary objectives: 1) to investigate the application of histological and histochemical methods in reconstructing developmental bio-chronologies and early life histories; 2) to refine the temporal precision of isotopic analysis of dentine collagen by developing a novel protocol that integrates micro-sampling techniques with high-resolution histomorphometrics; and 3) to synthesise data from enamel and dentine for a comprehensive understanding of early life development and dietary transitions. This study adopts an integrated multidisciplinary bioarchaeological approach, conducting histomorphometric analysis on enamel and dentine across deciduous and permanent dentitions. It applies high-temporal resolution trace element analysis to enamel using LA-ICPMS and δ13C and δ15N isotope analyses through sequential micro-sampling to dentine of permanent teeth. Samples were selected from diverse archaeological contexts across the Italian peninsula, covering the Upper Palaeolithic, Copper Age, and Early Medieval periods, providing insight into diachronic variations in infant development and life history. Findings highlight the efficacy of histological and histochemical techniques in accurately determining growth rates, physiological stress, dietary shifts (particularly timing of weaning), and age at death in infant remains. The consistency and comparison between enamel and dentine underscores the enhanced insight obtained from integrating information from both tissues. Importantly, the newly proposed protocol significantly improves the temporal accuracy of dentine collagen analysis, facilitating precise chronological placement of the results over broad developmental associations. This study reaffirms the significance of teeth as valuable bioarchaeological instruments. By introducing and testing multidisciplinary methods, it provides deeper insights into early life history and cultural practices across diverse chronological contexts, highlighting the importance of advanced methodologies in extracting detailed, accurate, and nuanced information from past populations.

Segunda opinião formativa: qual a situação atual da epidemia do vírus Ebola e porque se estendeu temporal e geograficamente?

Desde a identificação do vírus Ebola há aproximadamente 40 anos, epidemias periódicas veem ocorrendo na África Central, particularmente em Uganda, Gabão, República Democrática do Congo, Sudão e Angola. Recentemente, em 2014, pela primeira vez, um surto é reconhecido e notificado no oeste Africano transformando-se na mais complexa, extensa e duradoura epidemia de Ebola já registrada na história. Investigação epidemiológica realizada com dados de registro hospitalares e entrevistas com pacientes e seus familiares sugere que os primeiros prováveis casos iniciaram em Guiné em dezembro de 2013, espalhando-se para Libéria e Serra Leoa, países onde ocorre mais intensamente a transmissão. A Organização Mundial de Saúde (OMS) foi notificada oficialmente do surto pelo Ministério da Saúde de Guiné em 21 de março de 2014. Seis países (Mali, Nigéria, Senegal, Espanha, Reino Unido e Estados Unidos da América) notificaram pequeno número de casos importados dessa região e entre eles alguns apresentaram disseminação localizada, estando todos atualmente em situação controlada. A maioria das epidemias de Ebola anteriormente descritas ocorreu em pequenas comunidades, vilas ou cidades da África Central, localizadas nas proximidades das florestas tropicais. Apesar da alta letalidade relatada, envolveram uma população menor, contrastando com a presente, que abrange áreas rurais e urbanas, alcançando capitais, de grande contingente populacional. Há mais casos e mortes nessa epidemia do que em todas as anteriores somadas. Sua duração também tem caráter único, já ultrapassando um ano de seu início. As epidemias anteriores foram controladas em período aproximado de 2 a 5 meses. O grande movimento populacional entre fronteiras, através de estradas comuns que interligam esses países, relacionada à intensa atividade de comércio, contribuiu também para a disseminação do Ebola. Outros fatores significativos se relacionam à susceptibilidade da maioria da população, uma vez que essa foi a primeira epidemia a ocorrer na região e inexperiência dos órgãos de saúde responsáveis frente à epidemia de tamanho porte. Assim, a epidemia de Ebola que iniciou como crise de saúde para os três países envolvidos avolumou-se, transformando-se em crise social, econômica, cultural, humanitária e de segurança, com repercussão global. A estrutura do sistema de saúde já precária na região colapsou com o progredir da epidemia de Ebola, que levou à morte milhares de indivíduos, incluindo contingente significativo de profissionais de saúde, já em número inferior ao necessário para atender a população. Apesar desse cenário dramático e dos grandes desafios ainda presentes, muito se aprendeu durante o ano de 2014. Houve um ganho significativo de conhecimento no campo da patogenia e clínica da doença, repercutindo na melhor condução dos casos com melhora da sobrevida. Esforços e incentivos à pesquisa científica dirigida à produção de produtos médicos para prevenção e tratamento da doença foram desencadeados. Atualmente diferentes terapias e duas vacinas encontram-se em investigação. No contexto de um mundo globalizado, o impacto causado pelas doenças infecciosas emergentes e reemergentes não se restringe mais às localidades de origem e nem apenas ao setor saúde, repercutindo em todo o mundo, como temos presenciado nas últimas décadas e particularmente na presente epidemia do Ebola.

Circadian Rhythm And Profile In Patients With Juvenile Myoclonic Epilepsy And Temporal Lobe Epilepsy.

This study intended to compare the circadian rhythm and circadian profile between patients with juvenile myoclonic epilepsy (JME) and patients with temporal lobe epilepsy (TLE). We enrolled 16 patients with JME and 37 patients with TLE from the Outpatient Clinic of UNICAMP. We applied a questionnaire about sleep-wake cycle and circadian profile. Fourteen (87%) out of 16 patients with JME, and 22 out of 37 (59%) patients with TLE reported that they would sleep after seizure (p < 0.05). Three (19%) patients with JME, and 17 (46%) reported to be in better state before 10:00 AM (p < 0.05). There is no clear distinct profile and circadian pattern in patients with JME in comparison to TLE patients. However, our data suggest that most JME patients do not feel in better shape early in the day.

Temporal Auditory Processing And Phonological Awareness In Children With Benign Epilepsy With Centrotemporal Spikes.

The aim of this research was to analyze temporal auditory processing and phonological awareness in school-age children with benign childhood epilepsy with centrotemporal spikes (BECTS). Patient group (GI) consisted of 13 children diagnosed with BECTS. Control group (GII) consisted of 17 healthy children. After neurological and peripheral audiological assessment, children underwent a behavioral auditory evaluation and phonological awareness assessment. The procedures applied were: Gaps-in-Noise test (GIN), Duration Pattern test, and Phonological Awareness test (PCF). Results were compared between the groups and a correlation analysis was performed between temporal tasks and phonological awareness performance. GII performed significantly better than the children with BECTS (GI) in both GIN and Duration Pattern test (P < 0.001). GI performed significantly worse in all of the 4 categories of phonological awareness assessed: syllabic (P = 0.001), phonemic (P = 0.006), rhyme (P = 0.015) and alliteration (P = 0.010). Statistical analysis showed a significant positive correlation between the phonological awareness assessment and Duration Pattern test (P < 0.001). From the analysis of the results, it was concluded that children with BECTS may have difficulties in temporal resolution, temporal ordering, and phonological awareness skills. A correlation was observed between auditory temporal processing and phonological awareness in the suited sample.

Patterns Of Seizure Control In Patients With Mesial Temporal Lobe Epilepsy With And Without Hippocampus Sclerosis.

Objective Patients with mesial temporal lobe epilepsy (MTLE) may present unstable pattern of seizures. We aimed to evaluate the occurrence of relapse-remitting seizures in MTLE with (MTLE-HS) and without (MTLE-NL) hippocampal sclerosis. Method We evaluated 172 patients with MTLE-HS (122) or MTLE-NL (50). Relapse-remitting pattern was defined as periods longer than two years of seizure-freedom intercalated with seizure recurrence. Infrequent seizures was considered as up to three seizures per year and frequent seizures as any period of seizures higher than that. Results Thirty-seven (30%) MTLE-HS and 18 (36%) MTLE-NL patients had relapse-remitting pattern (X2, p = 0.470). This was more common in those with infrequent seizures (X2, p < 0.001). Twelve MTLE-HS and one MTLE-NL patients had prolonged seizure remission between the first and second decade of life (X2, p = 0.06). Conclusion Similar proportion of MTLE-HS or MTLE-NL patients present relapse-remitting seizures and this occurs more often in those with infrequent seizures.

Diretrizes curriculares nacionais para o ensino médio: avaliação de documento

This text offers some contributions to the debate on the changes proposed to the National Curricular Directives to reform secondary education in Brazil. In the first part, the political and economic scene is evaluated as the context which generated the last stage of reforms in the educational field in the 90s. It questions the option for a model of structural reform (in the Brazilian case more restricted to the Program for Reform of Professional Education - PROEP) and of the curriculum, whose themes find their justification in the contemporary economic, social cultural and political context. It discusses the use of a model that bases itself on experiences developed in other countries and takes the international orientation of the multilateral organizations as its theoretical methodological reference, leaving out the peculiarities and injunctions of the Brazilian political administrative system. Such a policy measure can increase the tension and distance normally existing between government programs and the possibility of their real implementation in the school network. In the second part, it discusses the Resolution of the National Education Council, the Congress on Basic Education, no.3, of 16.698 that instituted the National Curricular Directives for secondary education, as well as the Legal Bases - Part I - of the National Curricular Parameters for secondary education. The analysis of official discourse takes Bardin's (1977, p. 209) proposals as its methodological reference for the models of structural analysis, seeking to make the implicit values and the connotations of the legal texts explicit

Educação a distância e efeitos em cadeia

This article is divided into two parts. The first presents two abstract arguments that constitute the starting point for the development of the second part, which is directed towards discussing some aspects of the distance learning policies, i.e., the role of public authorities in encouraging and shaping this type of education. First of all, it is intended to establish some assumptions to understand the emergence of this phenomenon and some of its conditioning factors and consequences; then to suggest some analytical tools to allow us to reflect on public policy in this area.

Tradução para a língua portuguesa e adaptação cultural do questionário Rowe modificado para atletas arremessadores

OBJECTIVE: Study was to translate and culturally adapt the modified Rowe score for overhead athletes. METHODS: The translation and cultural adaptation process initially involved the stages of transla tion, synthesis, back-translation, and revision by the Translation Group. It was than created the pre-final version of the question naire, being the areas function and pain applied to 20 athletes that perform overhead movements and that suffered SLAP lesions in the dominant shoulder and the areas active compression test and anterior apprehension test and motion were applied to 15 health professionals. RESULTS: During the translation process there were made little modifications in the questionnaire in order to adapt it to Brazilian culture, without changing the semantics and the idiomatic concept originally described. CONCLUSIONS: The questionnaire was easily understood by the subjects of the study, being possible to obtain the Brazilian version of the modified Rowe score for over head athletes that underwent surgical treatment of the SLAP lesion.
