Abstract. Amazon forests play a significant role in the global C cycle by assimilating large amounts of CO2 through photosynthesis and by storing C largely as biomass and soil organic matter. To evaluate the net budget of C in the Amazon, we must also consider the amplitude and timing of losses of C back to the atmosphere through respiration and biomass burning. One useful timescale metric that integrates such information in terrestrial ecosystems is the transit time of C, defined as the time elapsed between C entering and leaving the ecosystem; the transit time is equivalent to the age of C exiting the ecosystem, which occurs mostly through respiration. We estimated the mean transit time of C for a central Amazon forest based on the C age during ecosystem respiration (ER), taking advantage of the large variations in CO2 in the atmosphere below the forest canopy to estimate the radiocarbon signature of mean ER (Δ14CER) using Keeling and Miller–Tans mixing models. We collected air samples to evaluate changes in the isotopic signature of the main ER sources by estimating the δ13CER. We collected air samples in vertical profiles in October 2019 and December 2021 at the Amazon Tall Tower Observatory (ATTO) in the central Amazon. Air samples were collected in a diel cycle from two heights below the canopy (4 and 24 m above ground level (a.g.l.)). Afternoon above-canopy samples (79 and 321 m a.g.l.) were collected as the background. For the campaign of October 2019, the mean Δ14CER ranged from 24 ‰ to 41 ‰ with both Keeling and Miller–Tans methods. In December 2021, mean Δ14CER ranged from 53 ‰ to 102 ‰. The δ13CER showed a smaller variation, being −27.8 ‰ ± 0.3 ‰ in October 2019 and −29.0 ‰ ± 0.5 ‰ in December 2021. The Δ14CER estimates were compared with the record of atmospheric radiocarbon from the bomb period, providing estimates of mean transit time of 6 ± 2 years for 2019 and 18 ± 4 years for 2021. In contrast to steady-state carbon balance models that predict constant mean transit times, these results suggest an important level of variation in mean transit times. We discuss these results in the context of previous model-based estimates of mean transit time for tropical forests and the Amazon region. In addition, we discuss previous studies that indicate that approximately 70 % of assimilated carbon is respired as autotrophic respiration in the central Amazon. Our results suggest that newly fixed carbon in this terra firme tropical forest is respired within 1 to 2 decades, implying that only a fraction of assimilated C can act as a sink for decades or longer.
The Pareto effect in tipping social networks: from minority to majority

Published: January 2025

Abstract. How do social networks tip? A popular theory is that a small minority can trigger population-wide social change. This aligns with the Pareto principle, a semi-quantitative law which suggests that, in many systems, 80 % of effects arise from 20 % of the causes. In the context of the transition to net-zero emissions, this vital 20 % can be a critical instigator of social tipping, a process which can rapidly change social norms. In this work, we asked whether the Pareto effect can be observed in social systems by conducting a literature review, placing a focus on social norm diffusion and complex contagion via social networks. By analysing simulation and empirical results of social tipping events across disciplines and a large parametric space, we identified consistent patterns across studies and key factors which help or hinder social tipping. We show evidence supporting a tipping point near 25 % of the total population within our compiled dataset. Near this critical mass, we observe a high likelihood for a social tipping event, where a large majority quickly adopts new norms. Our findings illustrate slight variations between modelling and empirical results, with average tipping points at 24 % and 27 %, respectively. Additionally, we show a range of critical masses where social tipping is possible; these values lie between 10 % and 43 %. These results indicate the potential, but not the inevitability, of rapid social change in certain susceptible populations and contexts. Finally, we provide practical guidance for facilitating difficult norm changes by (1) leveraging trusted community structures and building critical mass in clustered networks (particularly in the 10 %–43 % threshold range), (2) adapting strategies based on norm type and context, and (3) targeting groups with moderate preferences and network positions – avoiding reliance on highly central or well-connected individuals – to enable endogenous spread.
Some determinants of the post-pandemic weakness of household consumption
Authors: Martínez-Carrascal Carmen Martínez-Carrascal 
Published: January 2025

Rationale
Household consumption in Spain has shown considerable weakness following the pandemic and its recovery has been less marked than would have been expected based on income developments. This article characterises the types of households and the items in the consumption basket that have contributed most to this slackness.
Takeaways
•By consumption basket component, in 2023 average spending on durable goods (particularly cars) and semi-durable goods (in particular, clothing and footwear) posted the largest fall in real terms compared with 2019. Meanwhile, consumption linked to leisure and culture stood close to its pre-pandemic levels.
•By household type, the largest gaps in average household consumption compared to pre-pandemic levels are observed in high-income households and households where the reference person is between 35 and 54 or is a foreign national.
•Differences in consumption developments by type of household are related to heterogeneity across households in terms of both income developments and the composition of the consumption basket – specifically, the difference in the share of essential expenditure (food, rent, water and energy).

Sentiment Analysis of Indonesian Society Toward the Launch of iPhone 16 Using Naive Bayes, Random Forest, and KNN Algorithms
Authors: Christopher Ezra Manurung  , Hendra Mayatopani  
Published: January 2025

The development of smartphone technology, especially involving global brands like Apple, always attracts the attention of the world, including Indonesia. Every time Apple launches a new product, the public's response, particularly in Indonesia, often appears in the form of tweets on the social media platform Twitter, now known as X, which can be analyzed to reflect public views. This phenomenon presents an opportunity to understand how products are received in today's market. The dataset used in this study was obtained from tweets or comments from the Indonesian public between October and November 2024. The study found that 51.49% of the tweets fell into the positive sentiment category, 28.15% were neutral, and 20.35% were negative. Accuracy evaluation using three algorithms showed that Random Forest had the highest accuracy at 72.4%, followed by KNN with an accuracy of 66.9%, and Naïve Bayes with an accuracy of 66.3%. The results of this study indicate that the majority of the Indonesian public showed a positive sentiment toward the launch of the iPhone 16, reflecting high enthusiasm for the product. Furthermore, the Random Forest algorithm proved to be more effective in sentiment classification compared to KNN and Naïve Bayes, with higher accuracy.

Published: January 2025

The study aims to compare and analyze the levels of heavy metal contaminants in Solanum tuberosum (Irish Potato) and Daucus carota (Carrot) in Bokkos Local Government Area Plateau State, Nigeria, assessing potential health risks associated with consuming these crops. The research was focused to five heavy metals (Cd, Cr, Cu, Ni, and Pb) in Irish potato and carrot sample from five different farms. The concentrations of these metals were gotten in decreasing order as follows: (DIM) Irish potato (A) Cd > Pb > Cr > Ni; (EDI) Irish potatoes (C) Cu > P B > Cr B > Ni B > Cd; (DI) carrot (A), Cu > B > Cu B > P Ni; and (DIMA) carrot(A) Pb Cd Cu Pb. The health risk assessment indices for the populations through the consumption of contaminated fish were estimated based on the daily intake of metals relative to the reference oral dose (RfD) for each metal. The mean concentration of Pb, Cd, Ni and Cd in tubers was less than the recommended values of FAO/WHO. The risk analysis factors considered were transfer factor (TF), EDI, DIM, bioaccumulation factor (BF), target hazard quotient (THQ), and Health risk index (HRI) evaluated for this study showed moderate to less high risk levels with respect to human exposure through consumption of the vegetables and not the soil as may be indicate in transfer factor. It is therefore recommended to monitor periodically the agricultural farmlands using a different analysis techniques with a view for possible remediation.

Kafka in de polder. De impact van langdurig onrechtmatig verblijf en ouderdom op de bestaansstrategieën en angst voor uitzetting van ongedocumenteerden
Deze bijdrage laat zien hoe langdurig onrechtmatig verblijf en ouderdom de bestaansstrategieën en deportability (angst voor uitzetting) van drie groepen ongedocumenteerde ouderen – asielzoekers, investeerders en avonturiers – beïnvloeden. We illustreren op basis van interviews dat deze groepen met het verstrijken van de tijd meer moeite hebben om hun aanvankelijke bestaansstrategieën vol te houden, wat resulteert in versterkte en verschuivende aspiraties. Tegelijkertijd verschuift het belang van deportability. Het verdwijnt bij investeerders naar de achtergrond, terwijl het bij asielzoekers en avonturiers plaatsmaakt voor detainability, ofwel angst voor vreemdelingenbewaring. Dit brengt kafkaiaanse situaties met zich en roept morele en instrumentele vragen op.

Authors: Bayer Eveline Wille , Gomes Luisa Pereira de Oliveira Zanetti , Martins Camila Marinelli , Gomes Ricardo Zanetti , Borges Pollyanna Kassia de Oliveira 
Published: January 2025

Justificativa e Objetivo: A sepse é uma resposta desregulada do hospedeiro à infecção que leva à disfunção orgânica com risco de vida, e é declarada uma prioridade de saúde global pela Organização Mundial da Saúde. O objetivo é comparar as condições clínicas, sociodemográficas de pacientes submetidos ou não a um protocolo hospitalar para diagnóstico e tratamento da sepse, e verificar o impacto nos desfechos associados a esta aplicação do protocolo. Métodos e resultados: Trata-se de um estudo epidemiológico, descritivo e analítico, do tipo coorte mista de base hospitalar, realizado no município de Ponta Grossa, Brasil, no período entre novembro de 2019 e outubro de 2020. As análises foram realizadas no ambiente R 4.0.4. Dos 184 pacientes que tiveram coleta de exames laboratoriais para diagnóstico de sepse, 97 (52,72%) eram do sexo masculino, 111 (60,33%) idosos, 134 (72,83%) apresentaram critérios clínicos e laboratoriais para sepse. Cerca de 44% receberam aplicação do protocolo de sepse. Foram admitidos 118 (88,06%) pacientes com infecção de origem comunitária, 58% tinham infecção de origem respiratória e 28% evoluíram para o óbito. Conclusão: A aplicação do protocolo de sepse não impactou no tempo de internação hospitalar, ou na mortalidade por sepse. Porém pôde-se aprofundar o conhecimento sobre o perfil do paciente séptico e as necessidades de melhorias.

Equipamentos de conectividades marítimas aplicados na Baia de Guanabara: estratégias de interconexão sustentável para o Rio de Janeiro
Authors: Filócomo Paola Serafim 
Published: January 2025

Segundo Vasconcelos (2001), a mobilidade é a "habilidade humana de movimentar-se em detrimento de condições físicas e econômicas individuais, e se referem às pessoas e não aos lugares", enquanto acessibilidade é relativa "aos meios físicos que viabilizam a consumação de deslocamentos, assegurando que os lugares dentro do espaço urbano se tornem acessíveis, e que os transeuntes, por sua vez, tenham mobilidade". A Baía de Guanabara no Rio de Janeiro possui grande potencial de conectividade entre suas bordas e a promoção da consolidação e expansão do sistema hidroviário já existente em suas águas causaria uma grande mudança no cenário atual da mobilidade urbana no tocante ao transporte público coletivo do estado. Na pesquisa em questão, são apresentados dados que comprovam as afirmações anteriores e justificam a proposta a ser apresentada que assunta um protótipo para o desenvolvimento de um modelo replicável para pontos de interesse para terminais em toda a baía e que, por possuir flexibilidade de montagem devido à escolha de um método construtivo modular e flutuante que pode ser resolvido por meio de encaixes de peças e que acompanha a variação do nível da água de acordo com as correntes de maré, pode adaptar-se à demanda atual e futura de cada um dos pontos sugeridos acompanhando a projeção da necessidade de uso do sistema ao longo do tempo.

Implementation Fidelity: The Disconnect Between Theory and Practice
Authors: Rhoads Christopher , Montrosse-Moorhead Bianca , Anglin Kylie , Lewis Catherine 
Published: January 2025

The current paper combines a conceptual analysis of major reviews of implementation fidelity studies (e.g., Dane & Schneider, 1998; Mowbray et al., 2003; O’Donnell, 2008) with reflections on fidelity measurement practice in field evaluations. It claims that practice is impoverished by the failure to recognize the existence of competing conceptualizations of fidelity, rooted in different theoretical perspectives. Different evaluation contexts may be better matched to one or the other of these perspectives. Confusion about how fidelity should be defined in a given funding program or evaluation prevents evaluators from instituting a maximally useful fidelity measurement program. Difficulties inherent to creating high-quality fidelity measures contribute to the problem. The causes and consequences of this disconnect between fidelity theory and fidelity practice are discussed herein. Preliminary suggestions for solutions are advanced.
