- Le PortugalPublication . Cardoso, João LuisL’estuaire du Tage est la région d’Europe avec la plus grande concentration de gobelets maritimes. C’est pourquoi plusieurs préhistoriens du xxe siècle, ont défendu une origine du gobelet maritime dans cette région. Dans ce contexte, les datations radiocarbone, en particulier celles de la cabane FM du site de Leceia à Oeiras, attestent une apparition du Campaniforme autour de 2750-2700 BC, à une période où les gobelets maritimes coexistaient déjà avec d’autres productions régionales campaniformes.
- Green surgery: a systematic review of the environmental impact of laparotomy, laparoscopy, and roboticsPublication . Cunha, Miguel F.; Neves, João Cunha; Roseira, Joana; Pellino, Gianluca; Castelo-Branco, PedroSurgery is the most energy-intensive healthcare sector, but data on the environmental impact of abdominal surgical techniques are limited. This systematic review aims to identify the most sustainable approach among open, laparoscopic, and robotic surgeries. We searched MEDLINE, Cochrane, and Web of Science databases (inception to March 2024) for studies on the carbon footprint of abdominal surgery, focusing on carbon dioxide equivalents (CO2e) or CO2 emissions. The Joanna Briggs Institute checklist was used to assess bias. (PROSPERO: 298486). Of 2155 records, eight cohort studies were included, showing low to moderate risk of bias but high heterogeneity. Two studies on hysterectomy found robotic surgery had the highest carbon footprint (12.0-40.3 kgCO2e) compared to laparoscopic (10.7-29.2 kgCO2e) and open surgery (7.1-22.7 kgCO2e). Another study found laparoscopic prostatectomy produced more emissions than robotic surgery (59.7 vs. 47.3 kgCO2e) due to higher disposable devices, surgery time and length of stay. Single-use devices in laparoscopic cholecystectomy emitted more CO2e than hybrid devices (7.194 vs. 1.756 kgCO2e). CO2 used in minimally invasive surgery had negligible environmental effects (0.9 kgCO2e). Qualitative subgroup analyses revealed significant differences between surgery types and measurement methodologies, contributing to data heterogeneity. Minimally invasive surgeries often have higher carbon footprints due to disposable tools and waste. However, one study showed robotic surgery may reduce the overall environmental impact by shortening hospital stays. Due to methodological heterogeneity across studies, definitive conclusions remain limited. Standardized life-cycle assessment methodologies and inclusion of clinical outcomes in future studies are urgently needed to clarify the environmental sustainability of surgical practices.
- Staying hooked: effective science engagement and communication in recreational fisheriesPublication . Pita, Pablo; Tracey, Sean; Arlinghaus, Robert; Bachiller, Eneko; Pinho-Duarte, Filipa; Ferter, Keno; Henriques, Filipe; Hook, Samantha; Hyder, Kieran; Irigoyen, Alejo; Jiménez, María P.; Laporta, Martín; Lejk, Adam M.; Leonard, Eoin; Olesen, Hans Jakob; Palmer, Freya; Pavičić, Mišo; Pontes, João; Pujol-Baucells, Marta; Radford, Zachary; Rangel, Mafalda; Roche, William; Rudd, Hannah; Ryan, Diarmuid; Sbragaglia, Valerio; Selles, Jules; Silva, Catarina N. S.; Skov, Christian; Strehlow, Harry V.; Taylor, Stephen; Veiga, Pedro; Venerus, Leonardo A.; Venturelli, Paul; Vertegaal, David; Weltersbach, Marc Simon; Wiech, Martin; Winkler, AlexanderThis abstract summarizes the results of two expert consultations conducted to gather insights into effective communication and engagement strategies in recreational fisheries. Effective science communication fosters knowledge, understanding, and trust in both science and management decisions. Public involvement and stakeholder engagement are essential for effective management. Simplifying complex research findings and using diverse communication tools enhance awareness and understanding. Strong communication strategies are necessary to implement sustainable recreational fisheries management frameworks. Funding for communication efforts is often insufficient but remains crucial for success. Participatory workshops and data-sharing arrangements enhance collaboration and involvement. Multi-stakeholder consortiums and tailored communication strategies strengthen stakeholder engagement and promote adaptive governance. Interdisciplinary outreach and strategic social media use play vital roles in raising environmental awareness.
- Avaliação de desempenho de uma empresa de ótica: Aplicação do balanced scorecard na AlgarvisãoPublication . Albano, João Carlos Marçalo; Matos, Nelson Manuel da Silva de; Baptista, Nuno Tiago Claúdio LeitãoExiste uma grande variedade de filosofias de gestão e performance bem definidas e documentadas. Escolher um modelo que seja apropriado numa dada cultura, monitorizando a performance da empresa, e realizar decisões baseadas em factos e dados, são os fundamentos subjacentes da gestão de performance. O Balanced ScoreCard neste contexto fornece à empresa uma visão de desempenho integrada, englobando quatro perspetivas. A perspetiva financeira permite acompanhar as consequências das ações tomadas na organização com resultados económicos, proporcionando uma perceção nítida da gestão da empresa. Os indicadores de desempenho financeiro ilustram a forma como a implementação e a execução da estratégia da empresa estará a contribuir para a melhoria dos resultados. A perspetiva do cliente resulta do objetivo de obter a satisfação e retenção do cliente. Permite alinhar as medidas essenciais para a obtenção de resultados com a satisfação, fidelidade, retenção, captação e lucratividade nos segmentos de mercado escolhidos. A perspetiva dos processos internos da empresa, implica que as atividades internas estejam focadas nos requisitos originados pelos indicadores voltados para os clientes. A perspetiva de aprendizagem e inovação desenvolve os objetivos e as métricas de forma a orientar a aprendizagem e o crescimento organizacional. Pretende-se com o auxílio deste instrumento, avaliar a empresa Algarvisão e atribuir medidas de desempenho financeiro e operacionais. Foram desenvolvidas medidas nas quatro dimensões do Balanced Scorecard com recurso à análise de Key Performance Indicators (KPI) obtidos a partir de informação disponível na empresa. Com este trabalho pretende-se do ponto de vista teórico, ajudar a consolidar e expandir o conhecimento existente sobre o BSC, permitindo explorar de que forma este modelo de gestão possa ser adaptado a um contexto específico, como o de uma empresa de ótica. Do ponto de vista prático, a investigação oferece dados que podem ser aplicados diretamente à empresa. Através da análise dos resultados, será possível avaliar como o BSC pode ser implementado de maneira eficaz, ajustando os indicadores de desempenho financeiro, de clientes, de processos internos e de aprendizagem e inovação à realidade do negócio.
- New record of the coral-boring sponge Amorphinopsis cf. excavans in Kane´ ohe Bay, Hawai´iPublication . Pontes, João Diogo; Cunha, Regina Lopes da; Vicente, Jan; Toonen, RobThe Hawaiian archipelago is currently recognized as a hub of species introductions. In Kāneʻohe Bay, several marine alien species have been reported over the last decades, including sponges, which benefit from its nutrient-rich waters. Here we report the presence and the coral excavating habit of the Indo-Pacific sponge Amorphinopsis cf. excavans in the bay. A thorough traditional taxonomic assessment is performed, along with a genetic analysis of both ribosomal and mitochondrial genes, revealing the identity of the sponge. The results underscore the polyphyletic nature of the genus and highlight the need for an integrative approach to resolve its phylogenetic framework. Existing literature on A. excavans and its extended distribution range justify its classification as a species complex until further clarification. Limited dispersal capabilities of sponge larvae and the species’ encrusting ability suggest an introduction by integrating the fouling community of trans-Pacific vessels. The sponge is actively boring into the two primary reef-building species of coral in the bay - Montipora capitata and Porites compressa, therefore posing a significant environmental threat to Hawaiʻi’s native ecosystem. Considering the expected increase in bioeroding sponges under future climate change scenarios, the development of management strategies is advised.
