The Influence of Entrepreneurship Education on TheEntrepreneurial Intention of Students Major in EconomicManagement in Higher Vocational Colleges
Authors: Yanling Yun , Hock Kway Eng
Published: October 2023

This research examines the impact of entrepreneurship education on entrepreneurial attitude and intention among students majoring in economic management in higher vocational colleges. The study reveals that entrepreneurship education has a positive and significant effect on both entrepreneurial attitude and intention. Furthermore, it finds that entrepreneurial attitude serves as a mediating factor in the relationship between entrepreneurship education and entrepreneurial intention. The research also highlights significant gender differences, indicating that male students exhibit higher average levels of entrepreneurial intention compared to female students. However, there were no discernible gender variations in entrepreneurial tendencies. Those with and without business experience demonstrate distinct disparities in entrepreneurial ambition, with those with business experience exhibiting stronger entrepreneurial intention.

Published: October 2023

El Área Recreativa Lago Gatún (ARLG), forma parte de las cuatro zonas propuestas en el Plan de Acción para el desarrollo de Turismo Verde en Áreas Protegidas de Panamá, sin embargo, hay pocos estudios sobre diversidad y conservación de sus recursos naturales, en particular su fauna, que pueda ser útil para demarcar senderos de interpretación. Con el objetivo de actualizar el listado sobre la Riqueza, Abundancia y Estado de Conservación de anfibios en el ÁRLG, se realizó entre los meses de abril y diciembre de 2021 un inventario de anfibios. Se utilizó el método de observación directa para el registro de individuos y el uso de claves taxonómicas para la identificación de las especies; los individuos no identificados in situ fueron fotografiados y contrastados con especímenes del Museo de Vertebrados de la Universidad de Panamá. Se registraron 575 individuos en 12 especies y 8 Familias.  Once de las doce especies reportadas son nuevos registros para el lugar. Las especies más abundantes fueron Engystomops pustulosus y Agalychnis callidryas con 277 y 88 individuos, respectivamente. Agalychnis callidryas fue la única especie en categoría de preocupación menor de acuerdo a la UICN.  El total de especies registradas para el ARLG resulta una importante contribución al conocimiento de la riqueza de anuros de la zona.
Presencia de Salmonella sp. en muestras de pollo crudo y de huevos de cuatro supermercados en Veraguas, Panamá.
Authors: Him Fábrega José , Castillo Johana
Published: October 2023

En el año 2013 se obtuvieron muestras de pollo crudo y huevos en supermercados de la localidad de Santiago de Veraguas. Un total de cuatro supermercados fueron escogidos, los cuales se clasificaron en aquellos que tenían su propia producción de los que no la tenían. Las muestras fueron procesadas para detectar Salmonella sp. Se obtuvo una frecuencia general de 70 % de positividad en las muestras de pollo en todas las muestras. Al analizar estadísticamente los cuatro supermercados, no se encontró diferencias significativas entre las casas comerciales. De las muestras de huevos solo se encontró una positiva en uno de los supermercados. Al comparar a los supermercados que tenían producción propia con los que vendían productos de otros, se estableció que existe la misma probabilidad de encontrar salmonelas en las carnes de pollo cruda.
acquisition of the third person singular allomorphs of the simple present tense in English by Panamanian senior-level learners of English
Authors: Moreno Botacio Cinthia , González-Johnson Aracelis M.
Published: October 2023

The purpose of this quantitative study with an exploratory and descriptive scope was to apply the concepts of the Markedness Differential Hypothesis (Eckman, 1977) and Similarity Differential Rate Hypothesis (Major & Kim, 1996) in the production of the allomorphs of the third person singular of the English simple present tense by Panamanian Spanish senior-level learners of English. The researchers used a custom-designed book containing images as a research instrument, administering it twice to the sample group. The data collected through this method was subsequently subjected to analysis employing concepts from auditory and acoustic phonetics. The simple descriptive statistics showed that the sample had mastered 64% of the allomorphs of the third-person singular of the English simple present tense. These results could be the base for further research with correlational and explanatory scopes with many participants to confirm or disregard the patterns found in this study.

Toward a Social Justice Emphasis in Preservice Teachers’ Inquiries in Small Liberal Arts Contexts
Authors: Mule Lucy
Published: October 2023

Scholars underscore the need to study core features and outcomes of preservice teacher (PST) inquiry. This qualitative study identifies facilitation as a key feature, and a social justice inquiry stance as an important outcome. The author analyzed PST inquiry reports from a graduate-level course, noting that fewer than half of the reports were focused on social justice and, despite a weak program emphasis, PSTs were adopting this inquiry stance. Analysis of student feedback surveys and instructor notes revealed that providing clear and structured processes, consistent written feedback, and frequent meetings with facilitator and peers were effective facilitation strategies. Additional strategies include teaching research skills prior to the teacher inquiry semester, building more collaboration opportunities, and a program-wide focus on social justice. The author asserts that these strategies could ease reported PST challenges and provides recommendations for developing and sustaining social justice-focused PST inquiry in small liberal arts teacher education programs.

Authors: Harper Tracy
Published: October 2023

In pursuit of more effective professional learning for early career teachers, this paper presents findings from a multiple case study of practitioner inquiry with beginning teachers. The study examined the lived experiences of Kelly, Sally, and Donna as they took up inquiry-oriented professional learning in their literacy classrooms. Over the course of a semester, the teachers identified a problem of practice, co-constructed professional learning plans, explored relevant professional learning, and implemented new literacy practices. The findings demonstrated that the individualized and responsive nature of inquiry-oriented professional learning supported the teachers in developing agency and self-efficacy as they addressed areas of dissonance in their classrooms.

Authors: Marcus Belinda Ihuoma , Madukwe Ekperi Paul
Published: October 2023

The study examined the effect of political environment on performance in selected deposit money banks in Enugu State, Nigeria. The study was aimed at determining the extent to which political instability affects goal attainment in selected deposit money banks in Enugu State. A sample size of 300 was used for the study. Out of the 300 copies of questionnaires that were distributed, 282 copies were correctly filled and returned while 18 copies were not returned. The descriptive survey research design was adopted for the study. The hypotheses were tested using simple linear regression statistical tools. The findings indicate that Political instability negatively affected goal attainment in selected deposit money banks in Enugu state (r = 0.874; t = 5.986; F= 1248.625; p < 0.05). Political interference negatively affected employee performance and employee satisfaction in selected deposit money banks in Enugu state (r = 0.919; t = 8.646; F = 1524.624; p< 0.05). Government policies and regulation had significant negative impact on productivity in selected deposit money banks in Enugu state (r = 0.874; t = 8.053; F= 902.444; p < 0.05). The study concluded that political environment had a significant negative effect on performance in selected deposit money banks in Enugu State, Nigeria. The study recommended that: deposit money banks should always monitor factors in the political environment which may impede its goal attainment and take consideration of changes which occur in the political environment when formulating their long-term strategic plans; deposit money banks should always resist every form of political interference in their operations in other to achieve optimum employee performance and employee satisfaction and; deposit money banks should seek to lobby or influence those government policies that can affect its productivity negatively and as well devise means of adapting to those government policies outside its control.
The relationship between neutrophil to lymphocyte ratio and diastolic dysfunction in patients with essential hypertension
Authors: Doğan Yasemin , Şarlı Bahadır
Published: October 2023

Aim: Diastolic dysfunction (DD), which often accompanies essential hypertension (HT), can progress to heart failure with preserved ejection fraction. Recent studies have shown an association between chronic inflammation and HT. In this study, we aimed to investigate the neutrophil lymphocyte ratio (NLR) in hypertensive patients with and without DD and the relationship between NLR and DD development.
Methods: The study included 50 patients with DD and 50 patients without DD. Left ventricular systolic and diastolic functions were evaluated by echocardiography in all patients. A complete blood count, C-reactive protein (CRP), and NLR were analyzed in blood samples obtained from the patients.
Results: There was no significant difference in demographic characteristics and biochemical values between the two groups. White blood cell count and NLR were significantly higher in the group with DD (p<0.001). There was a strong correlation between the presence of DD and NLR in hypertensive patients (r=0.814, p<0.001). Although CRP was between reference values in both groups, it was significantly higher in the group with DD compared to the group without DD (4.40±1.60 vs. 3.70±0.90, p=0.020).
Conclusion: NLR can be used to detect DD in patients with hypertension and is an easily accessible and inexpensive inflammatory marker.
Intravascular ultrasound application in the evaluation of left main coronary artery lesions
Authors: Yılmaz Yücel , Keleşoğlu Şaban
Published: October 2023

Although atherosclerotic left main coronary artery stenosis (LMCA) has a low rate in the coronary angiography series, they have significant cardiovascular mortality and morbidity rates because their disease affects a significant proportion of the myocardium. Therefore, in severe cases (?50% stenosis of the LMCA), coronary artery bypass grafting is the revascularization of choice. However, assessing LMCA disease severity involves anatomical and technical challenges. Coronary intravascular ultrasound may help to overcome these difficulties. In this article, we report a 73-year-old case of LMCA disease that was considered to be severe by visual assessment of coronary angiography, and surgical intervention was abandoned because of a minimal lumen area of more than 6 mm2 when IVUS was performed.

Decolonialidade e Geografia escolar nos anos iniciais: o livro didático e a lei 11.645/2008 em Vilhena (RO)
Authors: Casteleira Rodrigo Pedro , Diniz Eder Carlos Cardoso
Published: October 2023

Este trabalho abordou as relações possíveis entre o pensamento decolonial e o ensino da Geografia escolar indígena, nos anos iniciais, nos Livros Didáticos (LDs) distribuídos pela Semed de Vilhena (RO); em especial, como os livros da coleção “Bem-me-quer Mais”, que tratam as questões indígenas à luz da lei nº 11.645/2008 e se, de alguma forma, trazem a questão decolonial para o interior dos conteúdos trabalhados. A metodologia utilizada pauta-se na análise documental, bibliográfica e qualitativa. A coleção analisada pouco ou nada dialoga com a lei 11.645/2008 e a teoria decolonial. Ainda que a Base Nacional Comum Curricular (BNCC) trabalhe com a interculturalidade em suas unidades temáticas, o máximo que a coleção avançou foi em uma interculturalidade formal. A perspectiva decolonial parte da dinâmica de que os países e povos considerados subalternos, frente ao sistema econômico social global, possam estar em uma posição de protagonismo no campo da cultura, ciência, economia etc. Assim, a ausência desse tipo de posicionalidade, quanto às questões indígenas em material didático, acaba por reforçar os estigmas e processos de subalternização. Verifica-se, ainda, que a etnografia não é uma unanimidade nos LDs, na academia e nas salas de aula, e que há, ainda, um silenciamento das falas dos grupos minoritários, dentre eles, os indígenas.

Rupturas com a colonialidade do ser deficiente: por uma pedagogia decolonial anticapacitista nos preceitos de Paulo Freire
Authors: Oliveira Waldma Maíra Menezes de , Oliveira Ivanilde Apoluceno de
Published: October 2023

Apresenta-se um recorte teórico da tese “Narrativas de vida e o pensamento decolonial: na construção da integralidade do Ser Surdo na Amazônia tocantina”. O objetivo geral, neste artigo, foi apresentar a colonialidade do ser deficiente e as rupturas decoloniais, a partir da proposição de uma pedagogia decolonial anticapacitista nos preceitos de Paulo Freire. A metodologia fundamentou-se em uma pesquisa bibliográfica. Com essa produção percebeu-se que os estudos decoloniais precisam teorizar que a modernidade incidiu sobre os corpos, através da normalidade, não somente dos povos do campo, das águas, das florestas, dos quilombos, dos povos originários, de homens e mulheres pretas cis e trans, dos indivíduos pertencentes à comunidade LBGTQIAP+, das mulheres, mas também das Pessoas com Deficiência. Tal ação é necessária e urgente, pois esse coletivo, mesmo em um campo teórico do Sul global, ainda se torna o outro do outro. Assim, ilustra-se a necessidade de se pensar a genealogia de uma pedagogia decolonial anticapacitista nos preceitos freireanos.
Ensaiando a educação profissional e tecnológica no sistema prisional brasileiro: um estudo decolonial
Authors: Gomes Erbs Cintra de Souza , Amaral Dayvison Herbety Araújo
Published: October 2023

Este ensaio utiliza a pesquisa pós qualitativa participante como abordagem e a análise crítica do discurso como método para problematizar as relações entre a Educação Profissional e Tecnológica – EPT e o sistema prisional brasileiro, considerando a raça como marcador de diferença e desigualdade. A construção dos dados se deu por meio de deambulações e entrevistas com uma pessoa negra que experienciou o cárcere e a formação profissional. A partir da perspectiva decolonial, busca inspiração na mitologia do povo iorubá, nos orixás e na participação do sujeito da pesquisa deste estudo para questionar o humanismo e o cientificismo que sustentam a lógica colonial. Este ensaio questionou a categoria de ressocialização no sistema prisional brasileiro, defendendo uma EPT que considere a pluralidade dos sujeitos e suas múltiplas dimensões. A pesquisa mostrou que a EPT pode contribuir para a transformação social dos indivíduos privados de liberdade, restituindo seus direitos sociais e levantando suas vidas que foram despersonificadas pela lógica colonial.

Published: October 2023

BACKGROUND:

In adults with acute respiratory distress syndrome (ARDS), high-frequency oscillatory ventilation (HFOV) has been associated with higher mortality rates. Therefore, its use in children with ARDS is still controversial.

OBJECTIVES:

Evaluate the overall mortality of HFOV in children with ARDS and explore mortality-related risk factors; compare the outcome of using HFOV post-endotracheal intubation early (≤24 hours) versus late (≤24 hours).

DESIGN:

Retrospective (medical record review)

SETTING:

Pediatric intensive care unit in a tertiary care center in Saudi Arabia.

PATIENTS AND METHODS:

Data were collected from medical records of all pediatric patients with ARDS aged one week to 14 years, who were admitted to the pediatric intensive care unit (PICU) from January 2016-June 2019 and who required HFOV.

MAIN OUTCOME MEASURES:

PICU mortality.

SAMPLE SIZE AND CHARACTERISTICS:

135 ARDS patients including 74 females (54.8%), and 61 males (45.2%), with a median age (interquar-tile range) of 35 (72) months.

RESULTS:

The overall mortality rate was 60.0% (81/135), and most died in the first 28 days in the PICU (91.3%, 74/8). Of non-survivors, 75.3% (61/81) were immunocompromised, and 24.7% (20/81) were immuno-competent patients, 52 (64.2%) received inotropic support, 40 (49.4%) had a bone-marrow transplant (BMT) before HFOV initiation. Although the prone position was used in 20.7% (28/135) to improve the survival rate post-HFOV ventilation, only 28.6% (8/28) survived. In addition, altered code status or chemotherapy reported a significant association with mortality (
P
<.05). Interestingly, early HFOV initiation (≤24 hours) did not seem to have a high impact on survival compared to late initiation (>24 hours); (57.4% vs. 42.6%,
P
=.721).

CONCLUSION:

Immunocompromised and oncology patients, including post-BMT, reported poorer outcomes, and neither the prone position nor early use of HFOV improved outcomes. However, it is recommended to replicate the study in a larger cohort to generalize the results.

LIMITATIONS:

Retrospective single-center study.

Authors: Somdee Thidarat , Somdee Theerasak , Yangyuen Suneerat , Mungvongsa Aravan , Khiewkhern Santisith , Puapittayathorn Thanyathorn , Thitisutthi Sawan , Srikongpan Piyaporn , Keawmuanga Supattra
Published: October 2023

BACKGROUND:

The metabolic syndrome (MetS) is a universal disease of increasing prevalence, but the prevalence varies depending on ethnicity. There is a crucial need to assess the validity of anthropometric indicators and determine appropriate cut-off values for MetS screening.

OBJECTIVE:

Determine cut-off anthropometric indicators values for screening of MetS.

DESIGN:

Cross-sectional

SETTING:

Rural and urban areas of provinces with a high prevalence of MetS in the central region of Thailand.

SUBJECTS AND METHODS:

The subjects were recruited based on the International Diabetes Federation definition of MetS, which includes four anthropometric indicators. Receiver operating characteristic (ROC) curves were used to evaluate the sensitivity and specificity for different cut-off values of all novel indicators.

MAIN OUTCOME MEASURES:

The cut-off values for screening of MetS, which included neck circumference (NC), body roundness index (BRI), conicity index (C-index), and body shape index (BSI).

SAMPLE SIZE:

2520 participants

RESULTS:

The BRI and NC were the indices with higher areas under the curve, followed by the C-index and BSI. The optimal cut-off values for BRI and NC were 4.1 and 36.5 cm for males and 4.0 and 34.5 cm for females.

CONCLUSIONS:

This study defined the specific cut-off values for Thai working adults.

LIMITATIONS:

The participants might not be representative of all Thai adults and we may have overestimated MetS for Thai working adults because our research focus was on the highest prevalence of MetS in the central region of Thailand.
The relationship between asymptomatic atherosclerosis and hepcidin-25 in chronic kidney disease patients
Authors: Mohamed Osama Nady , Mady Ahmed Mohamed , Sedik Mohamed Mamdouh , Issa Ahmed S. , Mohamed Omima M. , Abdelhameed Nadia Ismail
Published: October 2023

BACKGROUND:

The most common and lethal consequence of chronic kidney disease (CKD) is atherosclerotic cardiovascular disease. The persistent inflammation present in CKD increases hepcidin levels. Iron accumulates in the arterial wall in atherosclerosis. Hepcidin-25 was thought to accelerate the development of atherosclerotic plaques by blocking iron release from macrophages. Therefore, we sought to determine the relationship between hepcidin-25 and asymptomatic atherosclerosis in non-dialysis CKD patients.

OBJECTIVES:

Investigate the relationship between hepcidin-25 and subclinical atherosclerosis in non-dialysis CKD patients.

DESIGN:

Cross-sectional

SETTINGS:

Outpatient clinic for urology and nephrology at a university hospital

SUBJECTS AND METHODS:

Participants above the age of 18 years included a group of healthy controls and a group of CKD patients who were not routinely maintained on hemodialysis. The latter group was further divided according to eGFR into CKD-3, CKD-4 and CKD-5 subgroups. We excluded patients with comorbidities, patients with chronic liver disease, and other conditions or habits. CBC, kidney function tests, and serum levels of hepcidin-25 (SH-25), TNF-α, IL-6, high-sensitivity C-reactive protein (hs-CRP), TC, TG, LDL-C and HDL-C were assessed. To measure carotid intima media thickness (CIMT) and determine presence of plaques, carotid ultrasonography was performed. The near or far walls of common carotid artery, bulb, and internal carotid artery were used to measure CIMT.

MAIN OUTCOME MEASURES:

SH-25 association and indicators of subclinical atherosclerosis.

SAMPLE SIZE:

128 participants, the control group (n=25) and the non-hemodialysis CKD patients (n=103)

RESULTS:

The CKD patients had significantly higher serum levels of markers of inflammation including IL-6, TNF-α, and hs-CRP (
P
<.001 for each) compared to the controls. There was a significantly higher level of TC, TG and LDL-C (
P
<.001 for each) and a lower level of HDL-C (
P
<.001) in the CDK patients compared to controls. SH-25 was considerably higher in all CKD subgroups, especially with progression of CKD. CIMT was increased in CKD patients especially CKD-4 and CKD-5 subgroups when compared to healthy participants (
P
<.001 for each). In the patient group, CIMT showed a positive correlation with SH-25, (r=.65 and
P
<.001), IL-6 (r=.65,
P
<.001), TNF-α (r=.71,
P
<.001), and hs-CRP (r=.52,
P
<.001). The ROC curve study showed that SH-25 (AUC=.86,
P
<.001), IL-6 (AUC=.83,
P
<.001), hs-CRP (AUC=.72,
P
<.001), TNF-α (AUC=.82,
P
<.001) were strong predictors of subclinical atherosclerosis in the CKD patients.

CONCLUSIONS:

SH-25 and CIMT had a positive relationship in CKD patients. The ROC curve showed that SH-25 is a reliable predictor of carotid atherosclerosis. Therefore, we suggest that SH-25 is a vital biomarker of asymptomatic atherosclerosis.

Temperature Acclimation of Photosystem II Efficiency across Plant Functional Types and Climate
Authors: Neri Patrick , Gu Lianhong , Song Yang
Published: October 2023

Abstract. Modelling terrestrial gross primary productivity (GPP) is central to predicting the global carbon cycle. Much interest has been focused on the environmentally induced dynamics of photosystem energy partitioning and how improvements in the description of such dynamics assist the prediction of light reactions of photosynthesis and therefore GPP. The maximum quantum yield of photosystem II (ΦPSIImax) is a key parameter of the light reactions that influence the electron transport rate needed for supporting the biochemical reactions of photosynthesis. ΦPSIImax is generally treated as a constant in biochemical photosynthetic models even though a constant ΦPSIImax is expected only for non-stressed plants. We synthesized reported ΦPSIImax values from Pulse-amplitude modulated fluorometry measurements in response to variable temperatures across the globe. We found that ΦPSIImax is strongly affected by prevailing temperature regimes with declined values in both hot and cold conditions. To understand the spatiotemporal variability of ΦPSIImax, we analysed the dependence of the temperature acclimation of ΦPSIImax on plant functional type (PFT) and habitat climatology. The analysis showed that temperature acclimation of ΦPSIImax is shaped more by climate than by PFT for plants with broad latitudinal distributions or in regions with extreme temperature variability. There is a trade-off between the temperature range within which ΦPSIImax remains maximal and the overall rate of decline of ΦPSIImax outside the temperature range such that species cannot be simultaneously tolerant and resilient to extreme temperatures. Our study points to a quantitative approach for improving electron transport and photosynthetic productivity modelling under changing climates at regional and global scales.
Barriers to operational flood forecasting in complex terrain: from precipitation forecasts to probabilistic flood forecast mapping at short lead times

Abstract. As flood alert systems move towards higher spatial resolutions, there is a continued need to enable approaches that provide robust predictions of flood extent that adequately account for the uncertainties from meteorological forcing, hydrologic and hydraulic model structure, and parameter uncertainty. In flood forecasting, two primary sources of uncertainty are the quantitative precipitation forecasts (QPF) and the representation of the channel and floodplain geometry. This is especially relevant as simple approaches (e.g., HAND) are being used to map floods operationally at field scales (< 10 m). This article investigates the benefits of using a computationally efficient probabilistic precipitation forecast (PPF) approach to generate multiple flood extension scenarios over a region of complex terrain prone to flash floods. First, we assess the limitations of using a calibrated version of the gridded version of the WRF-Hydro model to predict an extreme flash flood event in the Greenbrier River Basin (West Virginia) on 24 June 2016. We investigated an ensemble methodology to combine operational High-Resolution Rapid Refresh (HRRR) QPF with radar-based Quantitative Precipitation Estimates, specifically MRMS QPE products. This approach was most effective to increase the headwaters streamflow accuracy in the first hour lead time, which is still insufficient to issue actionable flood warnings in operational applications. At longer lead-times, success was elusive due to epistemic uncertainties in MRMS rainfall intensity and HRRR rainfall spatial patterns. Furthermore, a QPF ensemble was used to generate an ensemble of flood heights using the HAND flood mapping methodology at different spatial resolutions. Results revealed a scale-dependency with increasing dispersion among the predicted flooded areas with increasing spatial resolution down to 1 meter. We hypothesize the overprediction of flooded areas at higher spatial resolutions reflects the increasing number of river reaches and the need for scale-aware representation of river hydraulics that impacts flood propagation in the river network.
Evaluation of isoprene emissions from the coupled model SURFEX-MEGANv2.1

Abstract. Isoprene, a key biogenic volatile organic compound, plays a pivotal role in atmospheric chemistry. Due to its high reactivity, this compound contributes significantly to the production of tropospheric ozone in polluted areas, and to the formation of secondary organic aerosols. The assessment of biogenic emissions is of great importance for regional and global air quality evaluation. In this study, we have implemented the biogenic emissions model MEGANv2.1 (Model of Emission of Gases and Aerosols from Nature, version 2.1) in the surface model SURFEXv8.1 (SURface EXternalisée in french, version 8.1). This coupling aims to improve the estimation of biogenic emissions using the detailed vegetation type-dependent treatment included in the SURFEX vegetation ISBA scheme. This scheme provides to MEGAN vegetation-dependent parameters allowing a more precise estimation of biogenic fluxes (e.g., leaf area index, soil moisture, wilting point data). The present study focuses on the assessment of the SURFEX-MEGAN model isoprene emissions. The evaluation of the coupled SURFEX-MEGAN model results was carried out by conducting a global isoprene emissions simulation in 2019 and comparing the simulation results with other MEGAN-based isoprene inventories. The coupled model estimates a total global isoprene emission of 442 Tg in 2019. The estimated isoprene is within the range of results obtained with other MEGAN-based isoprene inventories, ranging from 311 Tg to 637 Tg. The spatial distribution of SURFEX-MEGAN isoprene is consistent with other studies, with some differences located in low isoprene emission regions. Several sensitivity tests were conducted to quantify the impact of different model inputs and configurations on isoprene emissions. Using different meteorological forcings resulted in a +/-5 % change in isoprene emission using MERRA and IFS, respectively, compared with ERA5. The impact of using different emission factors data was also investigated. The use of PFT spatial coverage and PFT-dependent emission potential data resulted in a 14 % reduction compared to using the isoprene emission potential gridded map. A significant reduction of around 38 % in global isoprene emissions, was observed in the third sensitivity analysis, which applied a parameterization of soil moisture deficit, particularly in certain regions of Australia, Africa and South America. The significance of coupling the SURFEX and MEGAN models lies particularly in the ability of the coupled model to be able to be forced with meteorological data from any time period. This means, for instance, that this system can be used to predict biogenic emissions in the future. This aspect of this work is significant given the changes that biogenic organic compounds are expected to undergo as a result of changes in their climatic factors.
Mechanisms of Global Ocean Ventilation Age Change during the Last Deglaciation

Published: October 2023

Abstract. Marine radiocarbon (14C) is widely used to trace deep ocean circulation, providing insight into the atmosphere-ocean exchange of CO2 during the last deglaciation. Using two transient simulations with tracers of 14C and ideal age, we found that the oldest ventilation age is not observed at the Last Glacial Maximum (LGM). In contrast, the model shows a modestly younger ventilation age during the LGM compared to present day, mainly due to a stronger glacial Antarctic Bottom Water (AABW) transport associated with sea ice expansion. Notably, the ocean ventilation age is significantly older around 14–12 ka compared to the age at the LGM, with deep Pacific waters playing a predominant role, primarily caused by the weakening of AABW transport.
