Abstract. The Cape Verde Atmospheric Observatory (CVAO), which is influenced by both marine and desert dust air masses, has been used for long-term measurements of different properties of the atmospheric aerosol from 2008 to 2017. These properties include particle number size distributions (PNSD), light-absorbing carbon (LAC) and concentrations of cloud condensation nuclei (CCN) together with their hygroscopicity. Here we summarize the results obtained for these properties and use an unsupervised machine learning algorithm for the classification of aerosol types. Five types of aerosols, i.e., marine, freshly formed, mixture, moderate dust and heavy dust, were classified. Air masses during marine periods are from the Atlantic Ocean and during dust periods are from the Sahara Desert. Heavy dust was more frequently present during wintertime, whereas the clean marine periods were more frequently present during springtime. It was observed that during the dust periods CCN number concentrations at a supersaturation of 0.30 % were roughly 2.5 times higher than during marine periods, but the hygroscopicity (κ) of particles in the size range from ∼ 30 to ∼ 175 nm during marine and dust periods were comparable. The long-term data presented here, together with the aerosol classification, can be used as a basis to improve our understanding of annual cycles of the atmospheric aerosol in the eastern tropical Atlantic Ocean and on aerosol-cloud interactions and it can be used as a basis for driving, evaluating and constraining atmospheric model simulations.

Abstract. The ability to monitor, understand, and predict the dynamics of the terrestrial carbon cycle requires the capacity to robustly and coherently synthesize multiple streams of information that each provide partial information about different pools and fluxes. In this study, we introduce a new terrestrial carbon cycle data assimilation system, built on the PEcAn model–data eco-informatics system, and its application for the development of a proof-of-concept carbon “reanalysis” product that harmonizes carbon pools (leaf, wood, soil) and fluxes (GPP, Ra, Rh, NEE) across the contiguous United States from 1986–2019. We first calibrated this system against plant trait and flux tower net ecosystem exchange (NEE) using a novel emulated hierarchical Bayesian approach. Next, we extended the Tobit–Wishart ensemble filter (TWEnF) state data assimilation (SDA) framework, a generalization of the common ensemble Kalman filter which accounts for censored data and provides a fully Bayesian estimate of model process error, to a regional-scale system with a calibrated localization. Combined with additional workflows for propagating parameter, initial condition, and driver uncertainty, this represents the most complete and robust uncertainty accounting available for terrestrial carbon models. Our initial reanalysis was run on an irregular grid of ∼ 500 points selected using a stratified sampling method to efficiently capture environmental heterogeneity. Remotely sensed observations of aboveground biomass (Landsat LandTrendr) and leaf area index (LAI) (MODIS MOD15) were sequentially assimilated into the SIPNET model. Reanalysis soil carbon, which was indirectly constrained based on modeled covariances, showed general agreement with SoilGrids, an independent soil carbon data product. Reanalysis NEE, which was constrained based on posterior ensemble weights, also showed good agreement with eddy flux tower NEE and reduced root mean square error (RMSE) compared to the calibrated forecast. Ultimately, PEcAn's new open-source regional data assimilation framework provides a scalable workflow for harmonizing multiple data constraints and providing a uniform synthetic platform for carbon monitoring, reporting, and verification (MRV) as well as accelerating terrestrial carbon cycle research.
Plantation Women and Children
Authors: Teeuwen Danielle 
Published: April 2022

In the period 1870-1940 over a million Javanese labourers travelled to Sumatra hoping for a better life. Although the literature focuses on the labour activities, working conditions, and wages of male workers, especially from 1900 onwards a substantial part of the hired labourers were women and children. This paper argues that in the late colonial period attempts were made to improve the conditions for family life on the plantations. These policies were aimed at creating a stable pool of workers in a context of widespread labour scarcity. However, improvements were slow, and when a labour surplus occurred during the Great Depression, women's wages and contracts were affected most, which shows the gendered labour policies on the plantations were very much driven by an economic rationale.

Nurses have a very big responsibility in carrying out their duties both to patients and their families. During the current Covid-19 pandemic the number of patients received by hospitals is not proportional to the number of nurses so that it will have an impact on increasing physical and mental workloads. This study aims to determine the relationship between the determinants of the physical and mental workload of nurses with the application of patient safety during the COVID-19 pandemic at Labuang Baji Hospital Makassar.This type of research is a quantitative research with a cross sectional study approach. The sampling technique used total sampling with a total sample of 53 people. Data analysis was carried out univariate, bivariate with chi-square test. The results showed that there was an influence between physical workload (p value = 0.001) mental workload (p value 0.017) on the Application of Patient Safety during the Covid 19 Pandemic Period at Labuang Baji Hospital Makassar. It is recommended for nurses to perform stress management and adequate rest so that their workload is reduced so that the application of patient safety can be carried out properly.

Programme for International Students Assessment (PISA) 2015 which highlighted Global Rating on Education Quality reported that Malaysia was ranked in the 52nd placing out of 72 countries in assessing students’ ability in Science and Mathematics using English language (OED, 2016). This implies that Malaysian students need to improve further on science and technology development. Therefore, this study looked into the learning strategies and problems students face in learning English for Science and Technology (EST) subject and the teaching strategies employed by the teachers. A total of 150 Form Four students from three selected schools were taken as samples for this study. Data was collected using questionnaires. The researchers conducted a structured interview with 27 students from three schools (in Kedah, Selangor and Negeri Sembilan). In order to triangulate the data, the researchers also carried out a classroom observation on the Form Four classes from each of the three states and analysed 30 sample scripts of EST report writing to look at the types of language problems made by students. The study applied a mixed method of quantitative and qualitative. Findings from the 150 students’ Likert-scale questionnaires were analysed using a One-Sample T-Test. The responses from the 27 students’ interviews were transcribed and analysed using content analysis. The observations carried out in the selected Form Four classes were transcribed in a narrative written report. Overall, the study depicts that the majority of the students face language problems in learning EST. Students were found to be lacking in applying appropriate learning strategies, and teachers still control EST classrooms. Through the findings, this study suggests that a comprehensive and effective learning and teaching strategy, also known as CALLA (Cognitive and Academic Language Learning Approach), will help students elevate their comprehension and application to understand scientific knowledge in a second language effectively.

Published: April 2022

Objectives:
This biomechanical study seeks to define the relative effectiveness of contemporary single and dual implant constructs for fixation of an extra-articular proximal tibia fracture model.

Methods:
An extra-articular proximal tibia fracture model was created using synthetic tibias. Four constructs were tested. Constructs included (1) lateral locked plate (LLP), (2) intramedullary nail (IMN), (3) combined LLP and IMN (PN), and (4) LLP and medial locked plate. Specimens were axially loaded through the medial plateau to evaluate construct stiffness and the ability to resist varus collapse.

Results:
Dual implant constructs were stiffer than single implant constructs in this model. Although DP and PN were stiffer than IMN at all loads tested, the difference was notable only for DP at higher loads. Isolated LLP provided insufficient stability to be tested at higher loads.

Conclusion:
Dual plate fixation provides the greatest resistance to varus collapse. In the clinical setting, consideration must be given to the fracture morphology, desired construct stiffness, and soft-tissue envelope in selecting the optimal construct to be used.
