Temporal variability of precipitation isotopes in Damascus, Syria — implications for regional climate change
Authors: Kattan Zuhair , Nasser Saeid 
Published: June 2023

AbstractRecords of stable isotopes (2H and 18O), deuterium excess (d-excess) and tritium (3H) values in precipitation (P) during 1990–2022, together with long-term time series (1919–2022) of air temperature (T) and P-amount values at the Damascus station, were analysed to explore the seasonal and annual variability patterns of those parameters in P and assess the vulnerability to climate change in this area. Variation of the annual average air T values over the period 1919–1969 shows an increase gradient of ≈ + 0.1 °C/decade. However, a remarkable much higher gradient (+ 0.64 °C/decade) is calculated for the period 1990–2022. The average P-amount value calculated for the last three decades (≈185 mm) was lower by ≈28 mm, compared to the value (≈213 mm), relative to the reference period (1919–1969). This significant decline in the annual P-amount value by ≈11–13%, accompanied by an annual heating of 0.2–0.6 °C/decade in the annual air T, is likely the result of the climate change affecting this area. The linear relationships between annual average δ18O and annual average δ2H values versus time over the period 1990–2019 indicate increased gradients in both stable isotopes (≈0.3–0.5‰ and ≈1.1–3.2‰ per decade for δ18O and δ2H, respectively), accompanied with a decrease gradient of ≈0.9–1.1‰ per decade in d-excess values. Variability of annual 3H concentrations towards low levels (< 6 TU) during the later years strongly suggests the return back towards the cosmogenic production of this radioisotope in the upper atmosphere. Information gained from this work would offer new insights to improve the understanding of the temporal variability of P isotopes and assess the risks associated with climate change on the natural water resources in the Eastern Mediterranean region.

AbstractAs an effective drag reduction and thermal protection technology, the opposing jet can guarantee the flight safety of the hypersonic vehicle. In this paper, the jet mode transition is realised by controlling the total jet pressure ratio value (PR) with a function. The jet mode transition from the long penetration mode (LPM) to the short penetration mode (SPM) uses an increasing function. However, the jet mode transition from SPM to LPM uses a decreasing function. The flow field reconstruction process of a two-dimensional axisymmetric blunt body model in the hypersonic flow is studied when the jet mode transition between SPM and LPM changes into each other. The flow field structures and wall parameters of the LPM and SPM transition processes are obtained. The results indicate that the drag and Stanton number both decrease in the transition stage from LPM to SPM, and this is beneficial for the improvement of the drag reduction and thermal protection effect. The peak values of drag and Stanton number fall by 36.39% and 46.40%, respectively. When the jet mode transforms from SPM to LPM, the Stanton number increases, and the drag force first increases and then decreases. However, the final drag reduction effect is not obvious. With the increase in the change rate of the total pressure ratio of the two jet transformation modes, the jet mode transition time is advanced, and the flow field changes more violently.

Published: June 2023

Abstract
Across the globe, airports are regarded as essential infrastructure needing protection. One of the major goals of an airport, as encouraged by the regulatory bodies and evoked through public expectation, is safety. However, a public environment, such as an airport, is vulnerable to crime. The Oliver Reginald Tambo International Airport (ORTIA) is Africa’s biggest and busiest airport, servicing approximately 19 million passengers annually. Moreover, tourism is a key component of a healthy economy. Therefore, safety and security are significant for sustainable tourism in South Africa. Thus, this paper used a quantitative inquiry to determine security professionals’ perceptions of crime at ORTIA. A non-experimental and randomized cross-sectional research design was used. Through random sampling, a total of 100 participants contributed to the study and yielded a representative percentage of 36%. Data were collected through online self-administered questionnaires from security personnel employed at ORTIA and analysed through descriptive analysis. The findings revealed that the most problematic crimes taking place at ORTIA were reported to be theft, mishandled baggage, automated teller machine (ATM) crimes, burglary, robbery, illegal immigrants and smuggling of drugs. Furthermore, most participants had witnessed a crime taking place at the airport. As informed by the participants, sustainable solutions are proposed in terms of crime prevention and intervention.

Published: June 2023

AbstractThis study identifies the link between women's asset ownership and women's empowerment. Women's empowerment is measured by their decision-making role related to their health, large household purchases, and their social interaction. Using Demographic and Health Surveys data for 18 countries from South Asia, the Middle East, and sub-Saharan Africa, we found that the women who owned assets were 14% more likely to be empowered compared with the women who did not own any asset (odds ratio: 1.14, 95% confidence interval: 1.10–1.185). At a disaggregated country level, asset ownership was positively and significantly associated with women's empowerment in nine countries, negatively associated in one country, and had no significant association in the other eight countries. This study provides important insights into the link between women's asset ownership and empowerment and may inform public policy related to gender equality through women's empowerment.
Power of inclusive leadership: exploring the mediating role of identity-related processes and conditional effects of synergy diversity climate in nurturing positive employee behaviors

Published: June 2023

AbstractBased on the fundamental principles of social identity theory, this study examines how inclusive leadership can help build employees' organizational identification, stimulate leader-directed helping behavior, and improve task performance by facilitating insider status and relational coordination. Furthermore, we explored how these relationships are conditional on the synergy diversity climate in a moderated mediation model. We collected temporally segregated data (n = 300) from employees in diverse workforces at three time intervals with a 2-week gap between intervals. The results support the indirect effects of inclusive leadership on employee outcomes through the development of perceived insider status and relational coordination. Additionally, these indirect effects are more pronounced at higher levels of a synergy diversity climate. In conclusion, our study offers critical insights into the diversity and leadership literature by answering why and under what conditions an inclusive leader can generate favorable employee outcomes.

B-SPLINE BASED METAMODEL OF THE THERMAL ANALYSIS OF THE WIRE ARC ADDITIVE MANUFACTURING PROCESS
Authors: Zani Mathilde , Montemurro Marco , Panettieri Enrico , Marin Philippe 
Published: June 2023

AbstractAmong additive manufacturing processes, wire arc additive manufacturing (WAAM) is one of the most promising methods for manufacturing complex near-net-shape parts, as it allows the layer-by-layer deposition of welded material at a high deposition rate. However, this technology is highly dependent on deposition conditions and thermomechanical phenomena during the process. Therefore, process simulation could be used to analyse the effects of different deposition parameters on the thermomechanical results to optimise the process. However, as the computing time required for this study may become prohibitive, a dedicated strategy is needed to reduce it while maintaining a good level of accuracy. In this study, only the thermal analysis of the process is investigated. An efficient metamodel based on B-spline entities is developed to emulate the thermal response of the WAAM process when building a mild steel four-layer wall structure. Thanks to B-spline entities, the temperature profile at different locations is approximated as a function of a subset of deposition parameters of WAAM process, and the results are compared with the simulated temperature profile resulting from a validation dataset.

Published: June 2023

AbstractDifficulties with emotion regulation are integral to borderline personality disorder (BPD) and its hypothesized developmental pathway. Here, we prospectively assess trajectories of emotion processing across childhood, how BPD symptoms impact these trajectories, and whether developmental changes are transdiagnostic or specific to BPD, as major depressive (MDD) and conduct disorders (CD) are also characterized by emotion regulation difficulties. This study included 187 children enriched for those with early symptoms of depression and disruptive behaviors from a longitudinal study. We created multilevel models of multiple components of emotional processing from mean ages 9.05 to 18.55 years, and assessed the effect of late adolescent BPD, MDD, and CD symptoms on these trajectories. Linear trajectories of coping with sadness and anger, and quadratic trajectories of dysregulated expressions of sadness and anger were transdiagnostic, but also exhibited independent relationships with BPD symptoms. Only inhibition of sadness was related to BPD symptoms. The quadratic trajectories of poor emotional awareness and emotional reluctance were also independently related to BPD. Findings support examining separable components of emotion processing across development as potential precursors to BPD, underscoring the importance of understanding these trajectories as not only a marker of potential risk but also potential targets for prevention and intervention.
L’interrogative in situ à la lumière des principes de ‘End-Weight’ et ‘End-Focus’

Published: June 2023

RésuméPartant de l’hypothèse de Coveney (1995) que la structure informationnelle influence la sélection de l’interrogative in situ ‘Tu fais quoi ?’ (SVQ), ce travail s’appuie sur les données du Corpus suisse de SMS (2009-2015) pour évaluer l’incidence des principes dits ‘End-Weight’ et ‘End-Focus’. En suivant l’étude de Coveney (1995), nous analyserons l’incidence des paramètres suivants : (i) longueur de la proforme Q et (ii) celle de la partie SVC; paramètres du (iii) Sujet, (iv) Verbe, (v) Complément; et (vi) identité du mot Q. Suite à l’analyse de 217 occurrences de SVQ (sur 425 QU), nos résultats corroborent, fût-ce avec quelques nuances, plusieurs tendances observées par Coveney (1995). En même temps, notre étude révèle que les tendances en cause, telles qu’elles s’observent dans le Corpus de SMS, prennent la forme plus extrême et tendent à fonctionner comme des environnements morphosyntaxiques à variabilité faible : en débouchant régulièrement sur l’emploi de SVQ, elles réduisent drastiquement les chances d’apparition d’autres variantes ex situ. Ces tendances s’expliqueraient par le fait qu’en français informel l’usage de SVQ est en train d’évincer d’autres variantes, principalement dans ces contextes linguistiques qui se sont avérés initialement propices à sa rapide propagation au 20e siècle (Farmer 2015).

Published: June 2023

AbstractObjective:A dietary pattern dominated by ultra-processed foods has been associated with non-communicable diseases in several studies. A previous study from 2013 found a high share of ultra-processed foods in Norwegian food sales. This study aimed to investigate the current share of ultra-processed foods in Norway and the development in expenditure on ultra-processed foods from 2013.Design:A repeated cross-sectional analysis of scanner data from the Consumer Price Index from September 2013 and 2019 and an investigation of the processing degree according to the NOVA classification system.Setting:Food sales in Norway.Participants:Norwegian grocery stores (n180, for both time periods).Results:The share of expenditure in 2019 was highest for ultra-processed foods (46·5 %) and minimally or unprocessed foods (36·3 %), followed by processed foods (8·5 %) and processed culinary ingredients (1·3 %). An increasing degree of processing was found for several of the food groups between 2013 and 2019; however, most effect sizes were weak. In 2019, soft drinks became the most frequently purchased food item, surpassing milk and cheese, with the highest expenditure in Norwegian grocery stores. Increases in expenditure on ultra-processed foods were mainly due to increased expenditures on soft drinks, sweets and potato products.Conclusions:A high share of expenditure on ultra-processed food was found in Norway, which may imply a high consumption of these foods. The change in expenditure of NOVA groups between 2013 and 2019 was small. Carbonated and non-carbonated soft drinks were the most frequently purchased products in Norwegian grocery stores and contributed to most of the expenditures.
Tariff Flexibility Amid Formation of Preferential Trade Agreements: WTO Law vs. PTA Law
Authors: Kim Jong Bum , Yoo Li 
Published: June 2023

AbstractThis paper examines the legal ramifications of using tariff flexibility arising from GATT unbound tariff lines or tariff overhangs under both WTO and preferential trade agreement (PTA) law when flexibility is exercised preferentially for PTA partners. Under WTO law, a WTO member that is a party to a PTA under GATT Article XXIV is required to use tariff flexibility on a non-discriminatory basis. However, PTA obligations including tariff elimination commitments and a standstill clause prohibit the WTO member from raising applied tariffs on imports from the PTA parties, thereby preventing the use of tariff flexibility on a non-discriminatory manner. In contrast, a WTO member entering into a PTA under the Enabling Clause may use tariff flexibility discriminatorily without violating WTO law. A WTO member has greater legal latitude in utilizing tariff flexibility if it forms a PTA under the Enabling Clause rather than under GATT Article XXIV. The discriminatory exercise of tariff flexibility by some WTO members in conformity with PTA obligations, but in violation of WTO law, is further evidence of the fragmentation of the world trading system, where WTO law is facing its limits.

AbstractDust deposition in northeastern Asia since the Last Glacial Maximum has previously been studied using a variety of archives. However, the mechanisms driving variability in dust are less well constrained. Here, we present records of the Nd‐Sr isotope and major element composition of sediments from Lake Tuofengling, a crater lake located in northeastern China, over the past ∼25 thousand years. The results indicate that the lithogenic fractions of the sediments are a mixture between aeolian dust and local volcanic detritus. Our provenance data suggest that the aeolian dust component is predominantly from the Mongolia Plateau, likely carried by the East Asian Winter Monsoon. Our isotope and calculated dust flux records exhibit similar changing patterns to proxies of global ice volume and the strength of Atlantic meridional overturning circulation, potentially implicating ice sheets and ocean circulation as the dominant drivers of the East Asian Winter Monsoon over this time interval.

AbstractChildhood trauma (CT) is associated with lower cognitive and social cognitive function in schizophrenia. Recent evidence suggests that the relationship between CT and cognition is mediated by both low-grade systemic inflammation and reduced connectivity of the default mode network (DMN) during resting state. This study sought to test whether the same pattern of associations was observed for DMN connectivity during task based activity. Fifty-three individuals with schizophrenia (SZ) or schizoaffective disorder (SZA) and one hundred and seventy six healthy participants were recruited from the Immune Response and Social Cognition (iRELATE) project. A panel of pro-inflammatory markers that included IL-6, IL-8, IL-10, tumour necrosis factor-alpha (TNFa), and C-reactive protein (CRP), were measured in plasma using ELISA. DMN connectivity was measured during an fMRI social cognitive face processing task. Patients showed evidence of low grade systemic inflammation and significantly increased connectivity between the left lateral parietal (LLP) cortex-cerebellum and LLP-left angular gyrus compared to healthy participants. Across the entire sample, IL-6 predicted increased connectivity between LLP-cerebellum, LLP-precuneus, and mPFC-bilateral-precentral-gyri and left postcentral gyrus. In turn, and again in the entire sample, IL-6 (but no other inflammatory marker) mediated the relationship between childhood physical neglect and LLP-cerebellum. Physical neglect scores also significantly predicted the positive association between IL-6 and LLP-precuneus connectivity. This is to our knowledge the first study that provides evidence that higher plasma IL-6 mediates the association between higher childhood neglect and increased DMN connectivity during task based activity. Consistent with our hypothesis, exposure to trauma is associated with weaker suppression of the DMN during a face processing task, and this association was mediated via increased inflammatory response. The findings may represent part of the biological mechanism by which CT and cognitive performance are related.

AbstractSchizophrenia is characterized by dysconnectivity syndrome. Evidence of widespread impairment of structural and functional integration has been demonstrated in schizophrenia. Although white matter (WM) microstructural abnormalities have been commonly reported in schizophrenia, the dysfunction of WM as well as the relationship between structure and function in WM remains uncertain. In this study, we proposed a novel structure-function coupling measurement to reflect neuronal information transfer, which combined spatial-temporal correlations of functional signals with diffusion tensor orientations in the WM circuit from functional and diffusion magnetic resonance images (MRI). By analyzing MRI data from 75 individuals with schizophrenia (SZ) and 89 healthy volunteers (HV), the associations between structure and function in WM regions in schizophrenia were examined. Randomized validation of the measurement was performed in the HV group to confirm the capacity of the neural signal transferring along the WM tracts, referring to quantifying the association between structure and function. Compared to HV, SZ showed a widespread decrease in the structure-function coupling within WM regions, involving the corticospinal tract and the superior longitudinal fasciculus. Additionally, the structure-function coupling in the WM tracts was found to be significantly correlated with psychotic symptoms and illness duration in schizophrenia, suggesting that abnormal signal transfer of neuronal fiber pathways could be a potential mechanism of the neuropathology of schizophrenia. This work supports the dysconnectivity hypothesis of schizophrenia from the aspect of circuit function, and highlights the critical role of WM networks in the pathophysiology of schizophrenia.

AbstractThe cystine transporter solute carrier family 7 member 11 (SLC7A11; also called xCT) protects cancer cells from oxidative stress and is overexpressed in many cancers. Here we report a surprising finding that, whereas moderate overexpression of SLC7A11 is beneficial for cancer cells treated with H2O2, a common oxidative stress inducer, its high overexpression dramatically increases H2O2-induced cell death. Mechanistically, high cystine uptake in cancer cells with high overexpression of SLC7A11 in combination with H2O2 treatment results in toxic buildup of intracellular cystine and other disulfide molecules, NADPH depletion, redox system collapse, and rapid cell death (likely disulfidptosis). We further show that high overexpression of SLC7A11 promotes tumor growth but suppresses tumor metastasis, likely because metastasizing cancer cells with high expression of SLC7A11 are particularly susceptible to oxidative stress. Our findings reveal that SLC7A11 expression level dictates cancer cells’ sensitivity to oxidative stress and suggests a context-dependent role for SLC7A11 in tumor biology.
