Dynamics and production of dissolved organic carbon in a large continental shelf system under the influence of both river plume and coastal upwelling

We examined the dynamics and production of dissolved organic carbon (DOC) on a large continental shelf in the northern South China Sea, which is largely shaped by a river plume and coastal upwelling, based on a cruise in summer 2008. The plume water extended from the mouth of the Pearl River estuary to the middle shelf and was characterized by high DOC concentrations, while the upwelled water occupying the nearshore area featured low DOC concentrations. Biological production of DOC was observed in both the river plume and the coastal upwelling zones with different behavior between regions. The system appeared to be autotrophic in terms of DOC throughout the plume, while in the upwelling circulation, the metabolism of DOC was mixed trophic. Nevertheless, the integrated net DOC production rate of 11.5 ± 6.9 mmol C m−2 d−1 in the upwelling zone was comparable to that in the plume (7.1 ± 7.0 mmol C m−2 d−1). The net DOC production correlated strongly with net consumption of dissolved inorganic carbon (DIC) and inorganic nutrients, suggesting that the net DOC production was highly coupled to net community production (NCP) in both the plume and upwelling zones. Both regimes had similar DOC/NCP partitioning, with 19–27% of NCP in the plume and 24–26% of NCP in the upwelling zones converted to DOC. A positive correlation was also found between particulate organic carbon (POC) and net DIC consumption, with higher POC production in the upwelling zones where large phytoplankton prevailed. Most NCP removal occurred through POC sinking and/or the diffusion and horizontal transport of DOC.
Semismooth Newton Method for Boundary Bilinear Control

We study a control-constrained optimal control problem governed by a semilinear elliptic equation. The control acts in a bilinear way on the boundary, and can be interpreted as a heat transfer coefficient. A detailed study of the state equation is performed and differentiability properties of the control-to-state mapping are shown. First and second order optimality conditions are derived. Our main result is the proof of superlinear convergence of the semismooth Newton method to local solutions satisfying no-gap second order sufficient optimality conditions as well as a strict complementarity condition.
TRANSFORMER MODELS FOR MULTI-TEMPORAL LAND COVER CLASSIFICATION USING REMOTE SENSING IMAGES

Abstract. The pixel-wise classification of land cover, i.e. the task of identifying the physical material of the Earth’s surface in an image, is one of the basic applications of satellite image time series (SITS) processing. With the availability of large amounts of SITS it is possible to use supervised deep learning techniques such as Transformer models to analyse the Earth’s surface at global scale and with high spatial and temporal resolution. While most approaches for land cover classification focus on the generation of a mono-temporal output map, we extend established deep learning models to multi-temporal input and output: using images acquired at different epochs we generate one output map for each input timestep. This has the advantage that the temporal change of land cover can be monitored. In addition, features conflicting over time are not averaged. We extend the Swin Transformer for SITS and introduce a new spatio-temporal transformer block (ST-TB) that extracts spatial and temporal features. We combine the ST-TB with the swin transformer block (STB) that is used in parallel for the individual input timesteps to extract spatial features. Furthermore, we investigate the usage of a temporal position encoding and different patch sizes. The latter is used to merge neighbouring pixels in the input embedding. Using SITS from Sentinel-2, the classification of land cover is improved by +1.8% in the mean F1-Score when using the ST-TB in the first stage of the Swin Transformer compared to a Swin Transformer without the ST-TB layer and by +1,6% compared to fully convolutional approaches. This demonstrates the advantage of the introduced ST-TB layer for the classification of SITS.
Critical Examination of Longshore Transport Rate Magnitude

Inconsistencies in the field data and predictions of longshore sediment transport (LST) rates associated with the CERC and Bagnold formulae are discussed. Practical errors in direct application of the formulae can result in overprediction of LST by a factor of up to 1.8. The degree of wave-averaging affects LST prediction by factors of 1.5 to 2.5. Use of the formulae with hindcast wave data results in overprediction of LST by factors of 2 to 5. Consideration of non-linear effects contradict laboratory findings that relate LST to wave steepness or surf similarity. Reasonable errors in field measurements potentially yield errors in the LST formulae by factors of 2 to 4. The functional dependence on wave height of the CERC and Bagnold formulae is validated by consideration of long-term shoreline change at long shore-normal structures.
Firm Value Factors: The Effect of Earning Per Share, Capital Structure, and Dividend Policy on Creative Business Companies

Firm value is one of the measurements used to gain investor and creditor confidence. A high company value will make investors believe in investing their capital or investing in a company, because a high company value indicates good company performance and is a measure of the high level of shareholder prosperity indirectly. This study aims to determine whether there is an influence between earnings per share (EPS), capital structure, and dividend policy on firm value. The companies studied are creative business companies listed on the Indonesia Stock Exchange in 2019 – 2022. This research is a quantitative study. The population in this study were consumer goods companies and the sample method used was purposive sampling. The data analysis technique used is descriptive statistics, multiple linear regression analysis, coefficient of determination (R2), partial test (t test) and simultaneous test using SPSS version 26.00. The results of the study found that earnings per share has a significant effect on firm value, dividend policy has a significant effect on firm value, capital structure has no effect on firm value. The result of futher research found that earning per share, capital structure, and dividend policy simultaneously has a significant impact on firm value.
Multiorder Sequential Joint Inversion of Gravity Data With Inhomogeneous Depth Weighting: From Near Surface to Basin Modeling Applications

We have established a workflow for a multiorder sequential joint inversion (MOSJI) of gravity and gravity gradients, that aims at modeling vertically stacked sources in various geological scenarios. We consider the joint inversion of the gravity data and one of the $h$ th-order derivatives of the gravity data. The first step involves separate inversions, which are fundamental to fully exploit the different wavelength-content of the two quantities to invert. The joint inversion is warranted by using the scheme of a sequential joint inversion with a cross-gradient constraint. The algorithm is able to exploit different types of a priori information, such as compactness and inhomogeneous model-weighting function. First, we test this approach on a realistic synthetic model from the SEg Advanced Modeling (SEAM) Phase I model, involving salt and mother salt structures. Then, we consider a synthetic model containing either shallower or deeper karst cavities. These tests produced a better modeling of both shallower and deeper sources, when compared to the separate unconstrained inversions. Thanks to these good results, we apply our method to a real case for cavity detection in Southern Spain. The method shows an accurate modeling of the expected sources. In all the aforementioned tests, we obtain a strong decrease of the cross-gradient values and a meaningful linearization in the scatter plots of physical parameters, both indicating the good performance of the joint inversion.
Obstacles for the Sustaintability of Micro, Small and Medium-Sized Enterprises

: The objective of this study is to identify the obstacles faced by Mexican SMEs in implementing sustainability based on the size of the company. The research has a quantitative, descriptive, non-experimental, and cross-sectional approach. The population comprises Mexican SMEs from various states covering the north, northwest, central, and southeast regions of the country, from which a sample of 4,106 Mexican SMEs was determined. Information was gathered through an online questionnaire directed at the owner or manager of the company. The results of this study indicate that there are obstacles in implementing sustainability in at least two sizes of companies within the population. Conclusion: the main barrier for micro and small enterprises is the perception that implementing sustainable development is too costly for the company, followed by lack of training for company personnel and the complexity of applying environmental regulations. Whereas for medium-sized enterprises, environmental regulations and their complex application are their main barriers.
How does environmental perception affect the willingness of university students to return home to start a business?

Abstract Entrepreneurial intentions play a crucial role in predicting entrepreneurial behavior. Entrepreneurship is not a solitary individual endeavor, but rather, it is interconnected with the interplay between the individual and society. Previous studies have not clearly distinguished the unique role of entrepreneurs as individuals engaging in the entrepreneurial process, and there remains a lack of research on the psychological processes of entrepreneurs’ interactions with other people and their surroundings, which leaves a gap to be filled in entrepreneurship research. Therefore, this study introduces the concept of entrepreneurial environment cognition and re-examines the “process of interaction between entrepreneurial environment and subjects. ” When university students return to their hometown to start a business, the entrepreneurial mindset and perspective towards the entrepreneurial environment in their hometown can significantly impact their entrepreneurial intentions. This study, based on data from 302 respondents, integrates insights from entrepreneurship and cognitive psychology research to illustrate the influence of entrepreneurship and cognitive psychology in the process of university students returning to their hometown to start a business. To ensure construct validity and reliability, Cronbach’s alpha, Composite Reliability, and heterotrait-monotrait ratio tests are adopted. Additionally, this study further explains the mechanisms underlying this relationship by outlining the role of entrepreneurial passion and policy support. The findings suggest that environmental perceptions contribute to the willingness of university students to return to their home town for entrepreneurship, while entrepreneurial passion acts as a bridge and presents a partially mediating role in the relationship. In addition, it was found that the pathway environmental perceptions—willingness to return to their home town for entrepreneurship was more significantly moderated by policy support. These findings also provide reference and suggestions for the government and other decision-making departments.
Reimagining the Quality of Life

In recent papers, I defend the intrinsic value of the interesting, and the intrinsic disvalue of the boring. My arguments introduce two claims with important implications for discussions of the quality of life. The first is that when it comes to experiences, there’s more value at stake than pleasure alone. The second is that there is value to cognitive engagement itself, even when it is unstructured by desires or reasons. This paper explores the important consequences these conclusions have for how we appraise the quality of life of subjects with dramatically impaired cognitive capacities (such as patients with advanced Alzheimer’s and patients in a persistent vegetive state). I examine whether such groups are capable of experiencing the interesting and, by extension, what degrees of self-awareness are required to experience the kind of cognitive engagement at stake in interesting experiences.
Plasma and Peritoneal Fluid Annexin A2 Levels in Patients with Endometriosis

Introduction Endometriosis is an inflammatory-related reproductive age disease characterized by the presence of endometrial cells outside the uterine cavity. Current laboratory practice does not provide specific markers for detecting and assessing the advancement of endometriosis in either plasma or peritoneal fluid. The severity of disease is assessed in stages from I to IV based on the results of laparoscopic inspection. The protein annexin A2 (ANXA2) has been reported to be associated with inflammatory processes. Aim of the Study The study aimed to investigate and compare ANXA2 protein concentration using the ELISA method in plasma and peritoneal fluid in a group of women with endometriosis compared to controls. Materials and Methods Biological material was collected during a multicenter, cross-sectional study, which was conducted at eight departments during elective laparoscopy from 53 women with and 40 women without endometriosis. Patients were divided by endometriosis stage and infertility status, and then compared with subgroups. Analysis included the Chi-square test for categorical variables, Mann–Whitney U-test and two-sided Wilcoxon rank-sum test for continuous variables. Results Women with endometriosis had significantly elevated plasma ANXA2 levels compared to women without endometriosis (mean concentrations 28.69 vs 19.61 ng/L, p=0.01). Differences in peritoneal fluid ANXA2 levels were statistically insignificant (mean concentrations of 23.7 vs 22.97 ng/L, p=0.06). Plasma concentrations in patients with stage III and IV endometriosis were significantly higher compared to controls (mean concentrations of 24.19 vs 19.71 ng/L, p=0.03). No such differences were observed in plasma when comparing stages I–II vs III–IV, and stages I–II vs controls (mean concentrations of 33.82 vs 24.19 ng/L, p=0.72 and 33.82 vs 19.71 ng/L, p=0.12, respectively). Comparison of samples from patients with or without infertility, primary or secondary infertility, endometriosis with or without infertility, and non-endometriosis with or without infertility showed no significant differences in the plasma nor in the peritoneal fluid concentrations. Conclusion ANXA2 is possibly involved in the pathogenesis of endometriosis, especially in advanced stages. Due to the limited group of tested samples, further studies are needed to confirm its role.
Faces of conflict: Interventionism and substantiveness in the

The effect of conflict frames on political participation has been an important and popular subject of study in political communication research. Nonetheless, results have been generally inconclusive. In this study, we conduct a survey experiment (n = 707) to assess how different types of conflict frames affect political participation. We specifically differentiate between level of journalistic intervention and substantiveness in conflict framing. To shed light on the underlying process behind conflict framing effects, we also investigate how these effects are contingent on emotions. Results indicate that different types of conflict frames did not result in direct effects on political participation. However, the study does point to indirect effects via emotions. Particularly anger and enthusiasm function as mediators of conflict framing effects on political participation.
Classification of tourism potential in Al-Qaseem, Saudi Arabia using GIS

The demand for tourism in the Kingdom o f Saudi Arabia (KSA) has increased and received real attention since 2000. This can be seen through the establishment o f the Supreme Commission for Tourism (SCT). The SCT seeks to assess and develop the tourism potential in the whole country considering all factors (spatial and non-spatial) that influence tourism within KSA. This thesis examined the tourism potential in Al-Qaseem in KSA. It sought to achieve two aims relating to the identification of the cultural and natural tourist attractions and their distribution and the examination o f how spatial relationships impact on tourist potentials in the region. Tourist site attractions in Al-Qaseem were identified through a questionnaire survey o f two samples: a main sample (teachers group) and non-probability sample (other groups) to lend validity to findings o f the main sample. The main results indicated that natural tourist resources were more preferred for both males and females. It was also found that there were 83 sites with tourist attractions in Al-Qaseem (61 cultural and 22 natural attractions). The level o f attraction o f these sites identified showed that there were 29 very attractive sites were (most o f them are natural sites); 51 o f medium attraction with 3 o f slight attraction. The gender variable, o f the demographic variables considered, most influenced the preferences o f participants. Geographical information systems (GIS) was used to analyse the spatial relationship between tourist sites, services, population distribution and the road network to enable the identification o f tourist areas and tours. The results showed that there are 39 areas that have tourist potentials varies in terms o f tourist attractions (natural, cultural and historical), and availability o f services which can be accessed within specific times. The results indicated that popular natural and historical areas have relatively poor accessibility and services. As a result, the recommendation for this thesis is that development priority could be given to these tourist areas. The examination o f the road network with the distribution o f tourist sites in Al-Qaseem showed that the region has some potential to develop many tourist tours for visiting both cultural and natural tourist sites.
Assessment of risk factors among cardiovascular patients: A WHO STEPS approach in Bangladesh

Non-communicable diseases (NCDs) have already become the leading cause of death in Bangladesh. Hence, the purpose of the study was to identify the prevalence and determinants of NCDs risk factors among cardiovascular patients in Bangladesh. This cross-sectional study was conducted among 355 cardiovascular patients, aged 18 years and above visiting several tertiary care hospitals in Bangladesh. A validated, structured WHO NCD STEPS questionnaire was utilized to collect information including blood glucose level and lipid profile. Among patients, 58.9% were males and 41.1% females. Tobacco use was observed in 28.7% of the patients and only 1.7% consumed alcohol. Low levels of physical activity were recorded among 44.5% of the participants. Most of the subjects (83.1%) consumed an insufficient amount of fruits and vegetables. The prevalence of overweight and obesity was 41.7% and raised blood pressure was noted among 56.9% of participants. Only 1.7% of respondents were reported to be free from any selected NCDs risk factors. The present study showed a high prevalence of NCDs risk factors among cardiovascular patients and demands a multisectoral approach by the government and other stakeholders to lessen the impact of NCDs.
Associations between resilience, technostress and reflective capacity in social pedagogy students: A structural equation modeling methodology

Understanding factors affecting student academic and life outcomes may be critical for social work programs and educational institutions. Therefore, this study aims to explore the relationships between resilience, technostress and reflective capacity among social work students. A cross-sectional non-experimental research design was used. One hundred and sixty-three social work students completed an online survey measuring technostress level, reflective capacity and psychological resilience. Data were analyzed using Pearson’s to estimate linear correlations, confirmatory factor analysis to ensure model fit and structural equation modeling with covariates to reveal the relationships between the measured constructs. The results indicated that resilience had a direct and negative effect on technostress, a positive and direct effect on reflective capacity and a negative indirect effect on technostress through reflective capacity. This means that social work students with higher levels of resilience had lower levels of technostress related to technology use were more likely to engage in reflective practices and had lower levels of technostress due to improved reflective capacity. These findings emphasize the significance of resilience and reflective practices in mitigating the negative effects of technology use among social work students. However, researchers should be cautious about generalizing findings due to the sample’s limitations and future investigations should consider longitudinal data from diverse populations.
