This study aims to determine whether Lion Air's service quality including pre-flight, in-flight, post-flight and covid-19 protocol service quality affect passenger satisfaction and loyalty of Lion Air passengers in Medan. This study uses a quantitative (causal) research method with data obtained from distributing questionnaires through the snowball sampling technique (nonprobability sampling method) and will be processed using SEM (Structural Equation Modeling) utilizing AMOS version 22.0 software. This research is conducted on 125 respondents with male and female characteristics, ranging from 18-60 by age, domiciled in Medan, and had at least 1 x domestic trip using Lion Air baggage facilities within the last 2 years. The results of the analysis of the Structural Equation Model (SEM) using AMOS version 22.0 software show that the variable pre-flight service quality has an insignificant relationship to passenger satisfaction, in-flight service quality has a significant relationship to passenger satisfaction, post-flight service quality has a significant relationship to passenger satisfaction, covid-19 protocol service quality has a significant relationship to passenger satisfaction, pre-flight service quality has a significant relationship to passenger loyalty, inflight service quality has a significant relationship to passenger loyalty, post -flight service quality has a significant relationship to passenger loyalty, covid-19 protocol service quality has an insignificant relationship to passenger loyalty, and passenger satisfaction has a significant relationship to passenger loyalty

La Expresión Corporal es considerada una herramienta fundamental para la expresión y comunicación. Por ello, el objetivo del presente trabajo fue analizar la formación en Expresión Corporal del profesorado de Educación Infantil de Extremadura. Se pasó el cuestionario sobre la formación del Maestro de Educación Infantil en Expresión Corporal a una muestra de 216 docentes de Educación Infantil de la Comunidad Autónoma de Extremadura. Los resultados muestran ciertas carencias en la formación específica en Expresión Corporal y la controversia originada del pensamiento de que debe ser un docente especialista quien se encargue de este tipo de trabajo con los alumnos y no el Maestro-Tutor de Educación Infantil. Además, se ha encontrado información preocupante sobre la importancia que consideran los docentes que debe tener la Expresión Corporal con respecto a la importancia que se le da desde los centros educativos en otros niveles o en áreas distantes de la Educación Física, así como que, en los centros rurales, son menos los maestros que imparten Expresión Corporal. Se concluye que los docentes de Educación Infantil no poseen la formación necesaria como para poder dedicar parte de su jornada a la Expresión Corporal, debiendo mejorarse la formación inicial y la formación de los maestros en activo.

Abstract. Body Expression is considered a fundamental tool for expression and communication. For this reason, this study aimed to analyses the training in Body Expression of the Early Childhood Education teachers of Extremadura. The questionnaire on the preparation of the Early Childhood Education Teacher in Body Expression was given to a sample of 216 Early Childhood Education teachers from the Autonomous Community of Extremadura. The results show certain deficiencies in the specific training in Body Expression and the controversy originated from the thought that it should be a specialist teacher who is in charge of this type of work with the students and not the Early Childhood Education teacher-tutor. In addition, worrying information has been found about the importance that teachers consider that Body Expression should have for the importance given to it by educational centres at other levels or in areas distant from Physical Education, as well as that, in rural centres, some fewer teachers teach Corporal Expression. It is concluded that Early Childhood Education teachers do not have the necessary training to be able to dedicate part of their day to Body Expression, and the initial preparation and preparation of active teachers must be improved.

Published: February 2023

Literature about elite sports management tends to focus on the analysis of qualitative level of its success factors, especially among developed countries. In consequence, the aim of this study is to perform a predictive causal analysis that examines the factors influencing the development of elite athletes within the Valle del Cauca region in Colombia. 171 valid surveys were performed to direct stakeholders of elite sports. The goodness of fit, the composite reliability, the discriminant validity and the proposed structural model were examined by using the partial least square path modelling via ADANCO software. Empirical results show that for the population under study, competitions (p=.000), sports talent (p=.002), administration of the system (p=.02) and the cultural aspects (p=.002) are the factors that have a direct and positive influence on development of athletes; whereas hypothesis of funding, infrastructure, coaches and scientific research were rejected. This article contributes to the existing literature by providing knowledge of the factors influencing the development of elite athletes within a developing region from a quantitative approach.

Published: February 2023

La población mundial envejece de forma progresiva, necesitando conocer las necesidades de las personas mayores para mejorar sus niveles de calidad de vida, en especial, a través del ejercicio físico. Actualmente, se desconocen los niveles reales de ejercicio físico en esta población, así como los niveles de calidad de vida y dependencia en muchas regiones mundiales. Por ello, el objetivo principal fue analizar los niveles de práctica de actividad física del adulto mayor, así como la asociación del ejercicio en su calidad de vida. Para ello, 344 adultos mayores de la Ciudad Autónoma de Buenos Aires (Argentina) respondieron a un cuestionario ad-hoc elaborado por un Comité de expertos y basados en herramientas validadas sobre ejercicio físico, dependencia y calidad de vida. Los principales hallazgos fueron que un 34.6% de la población no realiza actividad física semanalmente, gran parte de la población mostró tener alto nivel de independencia y se encontró asociación positiva entre las personas más activas y los mayores niveles de calidad de vida. Según estos resultados, se deben diseñar y aplicar nuevas estrategias de ejercicio físico comunitario para aumentar los niveles de calidad de vida e independencia incrementando el volumen y frecuencia de ejercicio físico en personas mayores, especialmente realizado de forma colectiva.

Abstract. The world's population is ageing progressively, necessitating an understanding of the needs of older people to improve their quality of life, particularly through physical activity. Currently, the actual levels of physical exercise in this population are unknown, as well as the levels of quality of life and dependency in many regions of the world. Therefore, the main objective was to analyse the physical activity levels of older adults, as well as the association of exercise on their quality of life. For this purpose, 344 older adults from the Autonomous City of Buenos Aires (Argentina) answered an ad-hoc questionnaire developed by a committee of experts and based on validated tools on physical exercise, dependence and quality of life. The main findings were that 34.6% of the population did not engage in weekly physical activity, a large part of the population showed a high level of independence, and a positive association was found between more active people and higher levels of quality of life. Based on these findings, new community physical exercise strategies should be designed and implemented to increase levels of quality of life and independence by increasing the volume and frequency of physical exercise in older people, especially done collectively.

Abstract. UNESCO in 2005 was the first institution to establish a universal concept of what is quality physical education. However, establishing parameters to measure such quality, either taking that concept as a reference or the variants that have arisen subsequently is a complex task that has triggered multiple scientific researches. This study invited Physical Education professionals to answer a questionnaire, which was adopted from the study by Ho et al. (2021) in QPE, as a blueprint to investigate professionals’ understanding of Physical Education development in Ecuador. A total of 374 (216 male and 158 female) Physical Education teachers and professionals were invited to participate in this study. The data were obtained from nine cities in Ecuador. The dimensions quality teaching in Physical Education had the highest score and the lowest scored dimension Plans for Feasibility and Accessibility of Physical Education. The overall average mean of the questionnaire was 6.05 from maximum ten. The instrument had excellent internal consistency (α = .985). The works in QPE are slightly above average. It carries the message that the recommendation for QPE is not fully achieved.

This review aims to highlight the potential of n-3 PUFAs and physical exercise in reducing pain intensity in women with primary dysmenorrhea. This type of research is a systematic review using comprehensive strategies such as searching for articles in research journal databases. The databases used are Pubmed/MEDLINE, Scopus, Web of Science, and Embase. The populations analyzed in this paper are: the potential of n-3 PUFAs and physical exercise to reduce primary dysmenorrhea. The inclusion criteria in this study were journals that discussed n-3 PUFAs, exercise, primary dysmenorrhea, and menstrual pain. The exclusion criteria in this study were disreputable international journals. For standard operationalization, This study follows the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). This review explains that N-3 PUFAs given at the right dose, around 1000 mg/day have the potential to reduce pain intensity by suppressing the production of pro-inflammatory cytokines and eicosanoids. In addition, N-3 PUFAs have the potential to prevent and reduce pain intensity by inhibiting prostaglandin synthesis. Progesterone is very important in women with primary dysmenorrhea in order to control prostaglandin secretion. This review explains that regular exercise with low to moderate intensity (30-75% of maximum ability) performed 3 times in 1 week can increase progesterone concentrations. Physical exercises that can be done to reduce pain intensity due to primary dysmenorrhea include stretching exercises, jogging, and yoga exercises.

Integrating Diffusion of Innovations and Theory of Planned Behavior to Predict Intention to Adopt Electric Vehicles in Rwanda
Authors: Chukwuma Paul
Published: February 2023

Purpose: Integration of the theory of planned behaviour and the Diffusion of innovations (DOI) theory to examine EVs low adoption intention in Rwanda.

Methodology: The research model involved the integration of the Theory of planned behaviour and the Diffusion of innovation. To build the conceptual framework, over 50 articles were collected from Google scholar and summarised using meta-analysis. Two hundred and twenty participants were surveyed in person using a questionnaire, with each construct having at least three questions to run the Partial least squares (PLS) Structural Equation Modelling (SEM).  Data were analysed using SmartPLS 4.0.

Findings: The study found that two factors of the Theory of planned behaviour TPB- attitudes and perceived behavioural control- positively impact EVs adoption intention while subjective norm does not. Three factors of diffusion of innovation (DOI)- trialability, compatibility, and observability- positively impact attitude towards EV adoption.

Unique Contribution to Theory, Practice and Policy: Findings from the research explain the low adoption of electric vehicles in Rwanda. They can serve as an objective basis for policymakers to upscale EV uptake in Rwanda and brings to perspective the context of Rwanda on factors of EV adoption.

Authors: Cecilia Cindy , Sugianto Julius Albert
Published: February 2023

Introduction: Indonesia has the most dengue outbreaks in the ASEAN region. Lack of diagnostic modality and poor sanitation especially in rural area hinders proper and prompt management of Dengue Fever.

Aim: Finding the early, simple, and reliable predictor of Dengue Shock Syndrome (DSS) in Indonesia.

Materials and Methods: A retrospective study reviewing the medical record of pediatric patient with dengue infection from 1 January 2016 to 31 March 2016 were conducted. Age, gender, dengue signs, and simple laboratory result were collected. The data acquired were then analyzed using logistic regression for multivariate analysis (P<0,05) to find the severity predictor.

Results: 80 cases of dengue infection were included, mean age was 7,7 ± 3.4 years old, the average length of hospital stay was 4.59 days. 28.75% of patients had DSS. From the multivariate analysis, it is found that lethargy (p= 0.00; OR 21.23), bleeding (p= 0.01; OR 0,04), cold extremities (p=0.00;OR=22.35), and increased haematocrit level (p=0.01;OR=4.72) has significant relationship with DSS while other indicator did not.

Conclusion: Patients presenting with lethargy, cold extremities, and increase in haematocrit level should be treated promptly and intensively as they are more likely to develop DSS compared to patients who did not.

The latest guidelines suggest transanal, endoscopic or surgical treatment depending on the size, nature and stage of the tumour, with non-specific post-treatment surveillance.
Reconstruction of Metacarpal Bone with Giant Cell Tumour by Metatarsal Bone: A Rare Case
Authors: Loh Li Loong  , Raffael B. Ismail  , Goh Kian Liang  , Kamarul Ariffin Khalid
Published: February 2023

Giant cell tumour (GCT) of the metacarpal bone is rare, and it behaves more aggressively with a higher recurrence rate as compared to other long bones. Modalities such as bone curettage with or without bone grafting, ray amputation, or wide resection and reconstruction have been described as surgical management for this condition. Wide resection (en block) is often preferred as it has a lower recurrence rate among the rests. Reconstruction techniques options available include vascularised or non-vascularised fibular graft, iliac crest strut graft with loss of metacarpophalangeal joint function or with metatarsal substitution resulting in a more preserved function of the hand. This case report is about a 15-year-old teenager girl with a giant cell tumor of her left second metacarpal bone, which was confirmed with a plain radiograph and magnetic resonance imaging. This case report focuses the operative technique of the metacarpal reconstruction using the third metatarsal bone. The aim was to preserve hand function and cosmesis while achieving good local control of the disease without compromising the lower limb function. The transfer of osteoarticular ligamentous complex of the third metatarsal bone for the reconstruction of the second metacarpal bone defects is a possible operative procedure that provides good cosmetic and excellent functional outcomes while not compromising the donor’s foot function.
Eyelid Abscess with Dacryocystitis due to Burkholderia pseudomallei
Authors: Chee Yik Chang
Published: February 2023

ANSWER

Melioidosis is an infection caused by Burkholderia pseudomallei, which is a Gram-negative, saprophytic bacterium. Melioidosis can present with a broad spectrum of clinical manifestations including pneumonia, skin and soft tissue infection, visceral organ abscesses, neurological disease, bone/ joint infection, and bacteraemia (Cheng & Currrie, 2005). Ocular disease is a rare presentation of melioidosis; periorbital or orbital cellulitis, eyelid abscess, endophthalmitis, and panuveitis were among the reported cases (Yaisawang et al., 2018; Chang, 2020). Eyelid abscess due to melioidosis is treated with surgical drainage and antimicrobial therapy, which consists of intensive phase (ceftazidime or meropenem) and eradication phase (trimethoprim-sulfamethoxazole or amoxicillin-clavulanic acid) (Dance, 2014).

Clinicians should maintain a high index of clinical suspicion of melioidosis in patients presenting with eyelid abscess in areas where melioidosis is endemic. Hence, antibiotic therapy should be initiated promptly in suspicious cases, and surgical drainage of the abscess is a crucial aspect of management besides standard antibiotic therapy.

The Effect of 16 : 8 Intermittent Fasting Diet on Cognitive Eating Behavior in Individuals with Metabolic Syndrome
Authors: Kunduracı Yasemin , Özbek Hanefi
Published: February 2023

Objective: The aim of this study is to determine the effect of intermittent fasting diet on cognitive eating behavior in individuals with metabolic syndrome.
Methods: This intervention-type study was conducted on 70 individuals with metabolic syndrome between the ages of 18 and 65 who were directed by a physician to an obesity counseling center. In the study, energy-restricted diets were planned similarly for all participants. Participants were randomly divided into 2 groups according to age and gender. The control group was followed up for 12 weeks with the frequent intermittent diet plan and the intervention group with the 16 : 8 model intermittent fasting diet plan. The general demographic characteristics of the participants were defined before the research. Three-factor Nutrition Questionnaire was applied before and after the study in order to define the cognitive eating behavior level.
Results: The majority of the participants are in the 54-65 age group. The research group is married (94%), has primary-secondary (52.3%) level of education, whose income is at or above the minimum wage (95.4%), is a housewife (43.1%), retired (24%)), and consists of individuals who are public employees (12.3%). There was no significant difference between the groups in the total score of the 3-Factor Nutrition Questionnaire before the intervention. In terms of the sub-components of the 3-Factor Nutrition Questionnaire, statistically significant differences were found in both groups during the diet in uncontrolled eating, conscious restriction, and emotional eating scores (P < .05).
Conclusions: As a result, it has been determined that the application of energy-restricted diet as frequent or 16 : 8 model intermittent fasting diet does not have any superiority over the components of cognitive eating behavior, uncontrolled eating, conscious restraint, and emotional eating. Both energy-restricted diet plans have similarly positive effects on cognitive eating behavior.

Abstract. For millennia, humans have gravitated towards coastlines for their
resource potential and as geopolitical centres for global trade. A basic
requirement ensuring water security for coastal communities relies on a
delicate balance between the supply and demand of potable water. The
interaction between freshwater and saltwater in coastal settings is,
therefore, complicated by both natural and human-driven environmental
changes at the land–sea interface. In particular, ongoing sea-level rise,
warming and deoxygenation might exacerbate such perturbations. In this
context, an improved understanding of the nature and variability of
groundwater fluxes across the land–sea continuum is timely yet remains out
of reach. The flow of terrestrial groundwater across the coastal transition
zone and the extent of freshened groundwater below the present-day
seafloor are receiving increased attention in marine and coastal sciences
because they likely represent a significant yet highly uncertain component
of (bio)geochemical budgets and because of the emerging interest in the
potential use of offshore freshened groundwater as a resource. At the same
time, “reverse” groundwater flux from offshore to onshore is of prevalent
socio-economic interest, as terrestrial groundwater resources are
continuously pressured by over-pumping and seawater intrusion in many coastal
regions worldwide. An accurate assessment of the land–ocean connectivity
through groundwater and its potential responses to future anthropogenic
activities and climate change will require a multidisciplinary approach
combining the expertise of geophysicists, hydrogeologists, (bio)geochemists
and modellers. Such joint activities will lay the scientific basis for
better understanding the role of groundwater in societally relevant issues
such as climate change, pollution and the environmental status of the
coastal oceans within the framework of the United Nations Sustainable
Development Goals. Here, we present our perspectives on future research
directions to better understand land–ocean connectivity through groundwater,
including the spatial distributions of the essential hydrogeological
parameters, highlighting technical and scientific developments and briefly
discussing the societal relevance of that connectivity in rapidly changing coastal oceans.
Observed Process-level Constraints of Cloud and Precipitation Properties over the Southern Ocean for Earth System Model Evaluation
Authors: Stanford McKenna Wallace , Fridlind Ann , Silber Israel , Ackerman Andrew , Cesana Greg , Mülmenstädt Johannes , Protat Alain , Alexander Simon , McDonald Adrian
Published: February 2023

Abstract. Over the remote Southern Ocean, cloud feedbacks contribute substantially to Earth system model (ESM) radiative biases. The evolution of low Southern Ocean clouds (cloud top heights < ~ 3 km) is strongly modulated by precipitation and/or evaporation, which act as the primary sink of cloud condensate. Constraining precipitation processes in ESMs requires robust observations suitable for process-level evaluations. A year-long subset (April 2016 – March 2017) of ground-based profiling instrumentation deployed during the Macquarie Island Cloud and Radiation Experiment (MICRE) field campaign (54.5° S, 158.9° E) combines a 95 GHz (W-band) Doppler cloud radar, two lidar ceilometers, and balloon-borne soundings to quantify the occurrence frequency of precipitation from liquid-phase cloud base. Liquid-based clouds at Macquarie Island precipitate ~ 70 % of the time, with deeper and colder clouds precipitating more frequently and at a higher intensity compared to thinner and warmer clouds. Supercooled cloud layers precipitate more readily than layers with cloud top temperatures > 0 °C, regardless of the geometric thickness of the layer, and also evaporate more frequently. We further demonstrate an approach to employ these observational constraints for evaluation of a 9-year GISS-ModelE3 ESM simulation. Model output is processed through the Earth Model Column Collaboratory (EMC2) radar and lidar instrument simulator with the same instrument specifications as those deployed during MICRE, therefore accounting for instrument sensitivities and ensuring a coherent comparison. Relative to MICRE observations, the ESM produces a smaller cloud occurrence frequency, smaller precipitation occurrence frequency, and greater sub-cloud evaporation. The lower precipitation occurrence frequency by the ESM relative to MICRE contrasts with numerous studies that suggest a ubiquitous bias by ESMs to precipitate too frequently over the SO when compared with satellite-based observations, likely owing to sensitivity limitations of space-borne instrumentation and different sampling methodologies for ground- versus space-based observations. Despite these deficiencies, the ESM reproduces the observed tendency for deeper and colder clouds to precipitate more frequently and at a higher intensity. The ESM also reproduces specific cloud regimes, including near-surface clouds that account for ~ 25 % of liquid-based clouds during MICRE and optically thin, non-precipitating clouds that account for ~ 27 % of clouds with bases higher than 250 m. We suggest that the demonstrated framework, which merges observations with appropriately constrained model output, is a valuable approach to evaluate processes responsible for cloud radiative feedbacks in ESMs.

Abstract. Carbonyl sulfide (COS) is a promising tracer for the estimation of terrestrial ecosystem gross primary production (GPP). However, understanding its non-GPP related sources and sinks, e.g., anthropogenic sources and soil sources and sinks, is also critical to the success of the approach. Here we infer the regional sources and sinks of COS using continuous in-situ mole fraction profile measurements of COS along the 60-m tall Lutjewad tower (1 m a.s.l., 53°24'N, 6°21'E) in the Netherlands. To identify potential sources that caused the observed enhancements of COS mole fractions at Lutjewad, both discrete flask samples and in-situ measurements in the province of Groningen were made on a mobile van using a quantum cascade laser spectrometer (QCLS). We also simulated the COS mole fractions at Lutjewad using the Stochastic Time-Inverted Lagrangian Transport (STILT) model combined with emission inventories and plant uptake fluxes. We determined the nighttime COS fluxes to be -3.0 ± 2.6 pmol m-2 s-1 using the radon-tracer correlation approach and Lutjewad observations. Furthermore, we identified and quantified several COS sources, including biodigesters, sugar production facilities, and silicon carbide production facilities in the province of Groningen. Moreover, the simulation results show that the observed COS enhancements can be partially explained by known industrial sources of COS and CS2, in particular from the Ruhr valley (51.5° N, 7.2° E) and Antwerp (51.2° N, 4.4° E) areas. The contribution of likely missing anthropogenic sources of COS and CS2 in the inventory may be significant. The impact of the identified sources in the province of Groningen is estimated to be negligible to the observed COS enhancements. However, in specific conditions, these sources may influence the measurements in Lutjewad. These results are valuable for improving our understanding of the sources and sinks of COS, contributing to the use of COS as a tracer for GPP.

R1=0.0257 for 1095 unique reflections with Fo>4σ (Fo) and 94 refined parameters. Electron microprobe analysis,
coupled with Mössbauer spectroscopy, resulted in the empirical
structural formula X(Na0.81Ca0.20K0.01)Σ1.02 Y(Fe1.252+Mg0.76Ti0.56Al0.42)Σ3.00 Z(Al4.71Fe0.273+V0.023+Mg0.82Fe0.182+)Σ6.00 T[(Si5.82Al0.18)Σ6.00O18]
(BO3)3O(3)(OH)3O(1)[O0.59(OH)0.41]Σ1.00, which was recast in the
empirical ordered formula, required for classification purposes:
X(Na0.81Ca0.20K0.01)Σ1.02 Y(Fe1.432+Mg1.00Ti0.56)Σ3.00 Z(Al5.13Fe0.273+V0.023+Mg0.58)Σ6.00 T[(Si5.82Al0.18)Σ6.00O18]
(BO3)3V(OH)3 W[O0.59(OH)0.41]Σ1.00. Dutrowite is an
oxy-species belonging to the alkali group of the tourmaline supergroup.
Titanium is hosted in octahedral coordination, and its incorporation is
probably due to the substitution 2Al3+ = Ti4+ + (Fe,Mg)2+. Its occurrence seems to be related to late-stage
high-T/low-P replacement of “biotite” during the
late-magmatic/hydrothermal evolution of the Permian metarhyolite.
Radiative sensitivity quantified by a new set of radiation flux kernels based on the ERA5 reanalysis
Authors: Huang Han , Huang Yi
Published: February 2023

Abstract. Radiative sensitivity, i.e., the response of the radiative flux to climate perturbations, is essential to understanding climate variability. The sensitivity kernels computed by radiative transfer models have been broadly used for assessing the climate forcing and feedbacks in global warming. As these assessments are largely focused on the top of atmosphere (TOA) radiation budget, less attention has been paid to the surface radiation budget or the associated surface radiative sensitivity kernels. Based on the fifth generation European Center for Medium-Range Weather Forecasts atmospheric reanalysis, we produce a new set of radiative kernels for both the TOA and surface radiative fluxes, which is made available at http://doi.org/10.17632/vmg3s67568.1 (H. Huang, 2022). By comparing with other published radiative kernels, we find that the TOA kernels are in agreement in terms of global mean radiative sensitivity and analyzed overall feedback strength. The unexplained residual in the radiation closure tests is found to be generally within 10 %, no matter which kernel dataset is used. The inter-kernel bias-induced uncertainty, as measured by the standard deviation of the global mean feedback parameter value, is typically no more than 10 % in the longwave and 20 % in the shortwave; this uncertainty is much smaller than the inter-climate model spread of the feedbacks. However, there exist more significant regional biases in kernel values, due to the dependence of radiative sensitivity on the atmospheric states, and this contributes to more significant radiation non-closure at the regional scale, such as in the Arctic and Southern Ocean regions. On the other hand, we find relatively larger discrepancies in the surface kernels. Although several kernels can achieve as good radiation closure compared to the TOA kernels, affirming the validity of kernel method for the surface radiation budget analysis, the non-closure residual in certain kernels may amount to over 100 % of the total radiation change. The intercomparison of the surface kernels reveals important biases, such as in the radiative sensitivity to air temperature in the lowermost atmospheric layers adjacent to the surface, which is of critical importance to the overall surface feedback strength.

Abstract. Identifying the drivers of soil organic carbon (SOC) stock changes is of the
utmost importance to contribute to global challenges like climate change,
land degradation, biodiversity loss, or food security. Evaluating the impacts
of land use and management practices in agriculture and forestry on SOC is
still challenging. Merging datasets or making databases interoperable is a
promising way, but still has several semantic challenges. So far, a
comprehensive thesaurus and classification of management practices in
agriculture and forestry has been lacking, especially while focusing on SOC
storage. Therefore, the aim of this paper is to present a first
comprehensive thesaurus for management practices driving SOC storage
(DATA4C+). The DATA4C+ thesaurus contains 224 classified and defined
terms related to land management practices in agriculture and forestry. It
is organized as a hierarchical tree reflecting the drivers of SOC storage.
It is oriented to be used by scientists in agronomy, forestry, and soil
sciences with the aim of uniformizing the description of practices
influencing SOC in their original research. It is accessible in Agroportal
(http://agroportal.lirmm.fr/ontologies/DATA4CPLUS, last access: 24 March 2022) to enhance
its findability, accessibility, interoperability, and reuse by scientists
and others such as laboratories or land managers. Future uses of the
DATA4C+ thesaurus will be crucial to improve and enrich it, but also to
raise the quality of meta-analyses on SOC, and ultimately help policymakers
to identify efficient agricultural and forest management practices to
enhance SOC storage.
Englacial Architecture of Lambert Glacier, East Antarctica

Published: February 2023

Abstract. The analysis of englacial layers using radio-echo sounding data enables the characterisation and reconstruction of current and past ice-sheet flow. Despite the Lambert Glacier catchment being one of the largest in Antarctica, discharging ~16 % of East Antarctica’s ice, its englacial architecture has been little analysed. Here, we present a comprehensive analysis of Lambert Glacier’s englacial architecture using radio-echo sounding data collected by the Antarctica's Gamburtsev Province Project (AGAP) North survey. We used an “internal-layering continuity index” (ILCI) to characterise the internal architecture of the ice and identify four macro-scale ILCI zones with distinct glaciological contexts. Whilst the catchment is dominated by continuous englacial layering, disrupted or discontinuous layering is highlighted by the ILCI at both the onset of enhanced ice flow (defined here as >15 ma−1) and along the shear margin, revealing the transition from internal-deformation-controlled to basal-sliding-dominated ice flow. These zones are characterised by buckled and folded englacial layers which align with the current ice-flow regime, and which we interpret as evidence that the flow direction of the Lambert Glacier trunk has changed little, if at all, during the Holocene. However, disturbed englacial layers along a deep subglacial channel that does not correspond to modern ice-flow routing suggest that ice-flow change has occurred in a former tributary which fed Lambert Glacier from grid north. As large outlet systems such as Lambert Glacier are likely to play a vital role in the future drainage of the East Antarctic Ice Sheet, constraining their englacial architecture to reconstruct their past ice flow and assess basal conditions is important.
Patterns of wintertime Arctic sea ice leads and their relation to winds and ocean currents
Authors: Willmes Sascha , Heinemann Günther , Schnaase Frank
Published: February 2023

Abstract. We use a novel sea-ice lead climatology based on satellite observations with 1 km2 spatial resolution to identify predominant patterns in Arctic wintertime sea-ice leads. The causes for the observed spatial and temporal variabilities are investigated using ocean surface current velocities and eddy kinetic energies from an ocean model (FESOM) and winds from a regional climate model (CCLM) and ERA5 reanalysis, respectively. The presented investigation provides clear evidence for the influence of ocean depth and associated currents on the mechanic weakening of sea ice and the accompanied occurrence of sea-ice leads with their characteristic spatial patterns. While the ocean influence on lead dynamics acts on a rather long-term scale (seasonal to inter-annual), the influence of wind appears to trigger sea-ice lead dynamics on shorter time scales of weeks to months and is largely controlled by individual events causing increased divergence.

رسم الصحابة للقرآن الكريم بطريقة مخالفة للقياس، لم يكن صدفة بل كان عن علم ودراية، ومن الظواهر الكتابية المخالفة للقياس، ظاهرة الزيادة لا سيما زيادة الواو في الرسم العثماني، وهي من أكثر الظواهر الكتابية في الرسم اضطراباً عند علماء الرسم، وعلماء النحو والصرف، فاضطربت آراؤهم وكثرت تأويلاتهم وتوجيهاتهم لهذه الظاهرة.وقد تنوعت اتجاهات العلماء في تعليل هذه الظاهرة، فكان الاتجاه المعروف عند المتقدمين التعليل اللغوي. ثم ظهر اتجاه جديد وجّه هذه الظاهرة نحو علم الدلالة والمعاني، حتى إذا جاء العصر الحديث ظهر اتجاه آخر وهو الاتجاه التاريخي الذي كشف عن علاقة رسم المصحف بما اعتاده الناس في الكتابة والخط، ثم توالت دراسة الظواهر الكتابية، فظهر اتجاه آخر علل هذه الزيادة بتعليلات صوتية.وقد أردت بهذا البحث بيان مواضع زيادة الواو بعد الهمزة المضمومة المتفق عليها والمختلف فيها في الرسم العثماني، وبيان أسرار هذه الزيادة وعللها.
De sitios arqueológicos a sitios sagrados: la visibilización de la espiritualidad maya y el proceso de resignificación patrimonial en el municipio de Tecpán, Guatemala
Authors: Picas Mathieu
Published: February 2023

Este artículo examina el proceso de resignificación patrimonial que ocurrió en Guatemala a raíz de la Guerra Civil (1960-1996) y de la violencia perpetrada hacia las poblaciones indígenas y sus expresiones religiosas y espirituales. Se analizarán diferentes casos de activación patrimonial en torno a vestigios arqueológicos en la región de Tecpán y su utilización como altares ceremoniales durante y después del conflicto armado. Se pretende discutir la conversión del parque arqueológico de Iximche’ en espacio crucial para la visibilidad de la espiritualidad maya en la región antes de que esta ganara otros espacios y se convirtiera en un elemento de identidad para parte de la población kaqchikel local. Ello permitirá abordar el proceso de apropiación del patrimonio arqueológico por parte de la población local en la actualidad mediante la creación de narrativas contrahegemónicas y la conversión de determinados yacimientos en altares modernos.
