ABSTRACT What can alliances with trees bring about when it comes to teaching experiences in the face of the Anthropocene? This text analyzes the encounters between biological sciences and the arts as ...seen throughout the “Art, science and technology” course. Having been provoked by Haraway’s (2021) concept of “companion species” and established a connection with works by artists and with authors of education and philosophy, its interest in thinking about what happens between material relations and the systems of signs involved in those exercises which have resulted in two book-objects produced within the course: Floresta de luz and Floresta². The trees call upon people to think of teaching as a laboratory-atelier of perceiving-creating forests and to pay attention to the fabulations between biological sciences and the arts.
RESUMO O que as alianças com as árvores podem ativar em experiências de ensino diante do Antropoceno? Partindo dessa pergunta, analisa-se encontros entre biologias e artes nas práticas da disciplina “Arte, ciência e tecnologia”. Mobilizado pelo conceito de “espécies companheiras” de Haraway (2021) e em diálogos com obras de artistas, autores da educação e filosofia, este texto se interessa por pensar no que acontece entre as relações materiais e os regimes de signos envolvidos em exercícios que resultaram em dois livros-objeto criados na disciplina: Floresta de Luz e Floresta². As árvores convocam as pessoas a pensarem o ensino como um laboratório-ateliê de perceber-fazer floresta e a darem atenção às fabulações que brotam pelas frestas, entre biologias e artes.
This article discusses the habit of politicians paying journalists per diem rates in exchange for media coverage. Although bribery and money incentives have been studied as practices that compromise ...the ethics of journalism in several African countries, this paper researches Guinea-Bissau as an example and establishes a distinction. Unlike bribery, the widespread payment of these stipends is legal, but it is chronically damaging for freedom of expression and professional integrity. Drawing on interviews, focus groups and ethnographic observation with professionals from national, local and community media, this paper documents the precarious state of journalism in Guinea-Bissau, particularly the sector's acute lack of financial resources and meagre wages. News sources, and dominantly the government and parties, organise multiple events, attracting coverage in exchange for remuneration. Accepting these payments is, for many journalists, the only possible mode of subsisting, despite compromising their independence. News coverage is consequently saturated with propaganda, and forms of investigative journalism are rare. This article argues that the payment of per diem rates, accepted as legitimate and common practice in several other countries, has led to a pervasive control of journalism.
The emergence of bacterial resistance due to the indiscriminate use of antibiotics warrants the need for developing new bioactive agents. In this context, antimicrobial peptides are highly useful for ...managing resistant microbial strains. In this study, we report the isolation and characterization of peptides obtained from the venom of the toadfish
Thalassophryne nattereri
. These peptides were active against Gram-positive and Gram-negative bacteria and fungi
.
The primary amino acid sequences showed similarity to Cocaine and Amphetamine Regulated Transcript peptides, and two peptide analogs—Tn CRT2 and Tn CRT3—were designed using the AMPA algorithm based on these sequences. The analogs were subjected to physicochemical analysis and antimicrobial screening and were biologically active at concentrations ranging from 2.1 to 13 µM. Zeta potential analysis showed that the peptide analogs increased the positive charge on the cell surface of Gram-positive and Gram-negative bacteria. The toxicity of Tn CRT2 and Tn CRT3 were analyzed in vitro using a hemolytic assay and tetrazolium salt reduction in fibroblasts and was found to be significant only at high concentrations (up to 40 µM). These results suggest that this methodological approach is appropriate to design novel antimicrobial peptides to fight bacterial infections and represents a new and promising discovery in fish venom.
Widespread events of cork oak mortality are disturbing the system and jeopardizing cork production. This research combined techniques to analyze in detail these events on a small scale. To understand ...the dynamics of cork oak mortality and the factors associated with it, a diachronic study was performed in two farms located in Évora, Portugal. The case studies were two nearby farms suffering from tree dieback since 2000. Aerial images of the area, taken in 2004 and 2012, were processed with GIS in order to detect dead trees and to calculate tree crown cover. Slope and aspect were obtained through cartographic and topographic maps. The intersection of those maps resulted in polygons with unique values for those characteristics. Mortality index and tree crown cover were calculated for each one of them. Maps of the kernel density of tree mortality were generated to select key spots for pests and diseases field survey. Detection of soil pathogens was performed using baiting method and molecular analyses. The analysis showed that both farms had the same predisposing and inciting factors associated with tree decline, such as the soilborne Phytophthora cinnamomi, sunlight exposure or soil disking. However, the relative importance of each factor varied among farms. As a result, the dieback processes also differed, despite their similarity regarding mortality intensity. The diachronic approach associated with field survey resulted in a better comprehension of the tree dieback on a small scale and proved its usefulness in future decision-making regarding tree mortality mitigation.
This article analyses two digital-native news organisations, BuzzFeed News UK and Vice News (UK), and explores how they use emotional forms of storytelling in their election reporting. Drawing on a ...qualitative textual analysis of 280 news articles published during the 2017 UK general election, we scrutinise the textual and visual elements of emotional storytelling across three distinct groupings: (1) language and tone; (2) visual, formatting, and interaction, and (3) production and editorial choices. We argue that BuzzFeed and Vice draw on an emotional vernacular to engage with and relate to their young audience, while simultaneously providing a gateway to convey sophisticated political content. Both organisations embrace internet culture in their reporting, drawing on subjective, confessional, and personalised forms of expression that characterise communication on social media. The journalistic work required to wrap long-form, analytical election reporting in an emotive narrative provides evidence of innovative audience-orientated practice. In doing so, BuzzFeed and Vice offer election coverage that is uniquely tailored to a younger audience.
Cancer patients with liver metastasis may be candidates for liver surgery and local interventional techniques as part of their treatment. Although rare in this setting, hepatopulmonary fistula has ...been described as a possible complication. The clinical picture may be atypical, and, without specific treatment, it usually has a dismal prognosis. As locoregional treatments (whether interventional or surgical techniques) in liver neoplasms are being more frequently used we need to include this entity as a possible differential diagnosis of local liver treatment complications.
The Iberian Peninsula has an extensive record of species displaying strong genetic structure as a result of their survival in isolated pockets throughout the Pleistocene ice ages. We used ...mitochondrial and nuclear sequence data to analyze phylogeographic patterns in endemic land snails from a valley of central Portugal (Vale da Couda), putatively assigned to
, that show an exceptionally narrow distributional range. The genetic survey presented here shows the existence of five main mitochondrial lineages in Vale da Couda that do not cluster together suggesting independent evolutionary histories. Our results also indicate a departure from the expectation that species with restricted distributions have low genetic variability. The putative past and contemporary models of geographic distribution of Vale da Couda lineages are compatible with a scenario of species co-existence in more southern locations during the last glacial maximum (LGM) followed by a post-LGM northern dispersal tracking the species optimal thermal, humidity and soil physical conditions.
O presente estudo de caso aborda a vivência de um adolescente de 15 anos de idade, destacando a angústia e a ansiedade de separação face à figura paterna, recentemente reclusa por motivo de ...parricídio.

In this case study, the life experience of a 15 year old adolescent is addressed, specially the anguish and separation anxiety concerning the father figure, recently arrested due to parricide. The process began with a defensive, reluctant and suspicious attitude by the patient, with the verification of significant suffering related to the internal management of past experiences and a feeling of internal and external stigmatization. The evaluation reflects a resilient and adaptive adolescent, contrary to what would be expected in view of his recent experiences. However, some signs of depressive behavior were evident, including abulia, asthenia, and anhedonia, in addition to feelings of uneasiness and hopelessness for the future. A proposal of psychological intervention through brief psychotherapy of psychodynamic orientation in order to allow the resolution of internal conflicts that can compromise personality development and establishment of interpersonal relationships. In addition to diminishing symptoms, the intention was to clarify, organize and transform the internal conflicts in sustainable elements. The psychotherapy process, in parallel with the changes in the adolescent's relational dynamics allowed the occurrence of significant changes, specially a less defensive attitude and the ability to think about himself, tolerate and develop his feelings and emotions.
