A simple kit to use computational notebooks for more openness, reproducibility, and productivity in research.

The ubiquitous use of computational work for data generation, processing, and modeling increased the importance of digital documentation in improving research quality and impact. Computational notebooks are files that contain descriptive text, as well as code and its outputs, in a single, dynamic, and visually appealing file that is easier to understand by nonspecialists. Traditionally used by data scientists when producing reports and informing decision-making, the use of this tool in research publication is not common, despite its potential to increase research impact and quality. For a single study, the content of such documentation partially overlaps with that of classical lab notebooks and that of the scientific manuscript reporting the study. Therefore, to minimize the amount of work required to manage all the files related to these contents and optimize their production, we present a starter kit to facilitate the implementation of computational notebooks in the research process, including publication. The kit contains the template of a computational notebook integrated into a research project that employs R, Python, or Julia. Using examples of ecological studies, we show how computational notebooks also foster the implementation of principles of Open Science, such as reproducibility and traceability. The kit is designed for beginners, but at the end we present practices that can be gradually implemented to develop a fully digital research workflow. Our hope is that such minimalist yet effective starter kit will encourage researchers to adopt this practice in their workflow, regardless of their computational background.

Quantitative description of six fish species' gut contents and prey abundances in the Baltic Sea (1968-1978).

The dataset presents a compilation of stomach contents from six demersal fish species from two functional groups inhabiting the Baltic Sea. It includes detailed information on prey identities, body masses, and biomasses recovered from both the fish's digestive systems and their surrounding environment. Environmental parameters, such as salinity and temperature levels, have been integrated to enrich this dataset. The juxtaposition of information on prey found in stomachs and in the environment provides an opportunity to quantify trophic interactions across different environmental contexts and investigate how fish foraging behaviour adapts to changes in their environment, such as an increase in temperature. The compilation of body mass and taxonomic information for all species allows approaching these new questions using either a taxonomic (based on species identity) or functional trait (based on body mass) approach.

Associação da dieta com o câncer colorretal: revisão integrativa / Association of diet with colorectal cancer: literature integrative review

Objetivo: analisar a produção científica nacional e internacional sobre a associação da dieta e câncer colorretal (CCR), no período de 2000 a 2008; estabelecer os fatores de risco e de proteção e as implicações para a enfermagem. Metodologia: revisão integrativa de literatura, de 14 artigos obtidos na íntegra com os descritores dieta; câncer colorretal, na base de dados LiIacs e Medline, mediante os critérios de inclusão: enfoque da relação entre dieta e o CCR em seres humanos; publicados em inglês, espanhol e português. Utilizou-se roteiro sistematizado de coleta de dados para análise da amostra. Resultados: os fatores de risco para CCR identificados foram consumo de carne vermelha, processada e exposição a altas temperaturas e fibras solúveis. Recomenda-se o consumo de fibras insolúveis, porém outros fatores dietéticos, ambientais, genéticos, sócio-econômico-culturais e geográficos devem ser analisados. Conclusões: os estudos analisados apresentaram níveis de evidência pouco fortes em relação à associação da dieta com CCR, o que indica a necessidade de estudos futuros com melhor delineamento metodológico. As intervenções de enfermagem devem favorecer a adoção de hábitos dietéticos e de vida mais saudáveis, fundamentados em evidências científicas.(AU)
