South African Generation Y students’ behavioral intentions to use university websites

University websites are increasingly crucial in meeting the evolving digital demands of students. To effectively manage university websites, it is necessary to first determine students’ behavioral usage intentions of university websites and the factors that influence their intentions, which forms the purpose of this study. Data were collected at a single point in time and described the characteristics of the sample. This study, involving 319 Generation Y students registered at two South African university campuses (one traditional and one university of technology campus), utilizes structural equation modeling to explore the predictive relationships among information quality, system quality, playfulness, ease of use, trust, attitude, satisfaction, and behavioral intentions related to university website use. The study underscores the pivotal role of the university’s website in shaping student satisfaction, with information quality standing out as a significant positive influence. Additionally, playfulness significantly impacts both satisfaction and overall attitudes toward university websites. The system quality of the university website is also noteworthy, showing a statistically significant positive effect on ease of use and fostering trust among students. Furthermore, satisfaction is anticipated by ease of use, creating a cascade effect where satisfaction predicts trust and trust predicts attitudes. Ultimately, students’ attitudes emerge as a critical predictor for their behavioral intentions to use university websites. The model exhibits acceptable fit indices, demonstrating substantial explanatory power (SRMR = 0.1, RMSEA = 0.06, IFI = 0.94, TLI = 0.93, CFI = 0.94). These findings offer insights for university management and web designers to enhance online platforms, fostering student satisfaction, trust, and usage.
Positive Feedback and System Resilience from Graphical and Finite-Difference Models: The Amazon Ecosystem—An Example

Abstract Positive feedback has the potential to create multiple steady states that divide system space into regions of distinct behavioral modes. Graphical analysis can be used to recognize systems likely to behave in this way. For example, positive feedback created by interactions among tropical forest, regional hydrology, and climate in the Amazon basin may produce multiple steady states. As deforestation progresses, one state—the normal forest with a high leaf area index—is stable and promotes system resilience. However, deforestation can cause the system to shift toward and past a second, unstable state at moderate levels of forest cover. The latter separates forest stability in the face of stress from runaway behavior and system collapse into an alternative grassland ecology. To test this inference, a two-dimensional finite-difference model has been constructed that includes parameterizations of the functions controlling feedback. Results of the experiment indicate that human-driven deforestation may.
Video Display Field Communication: Practical Design and Performance Analysis

Display field communication (DFC) is a spectral domain-based, unobtrusive display-to-camera (D2C) communication method in which a commercially available digital display serves as the transmitter and an off-the-shelf camera serves as the receiver. The data are transmitted through video and image frame sequences over D2C links in such a way that it do not obstruct the normal viewing experience. In this study, we propose a Video-DFC approach to detect data embedded in running videos. First, we propose the design of a frame packet structure which is used to facilitate encoding input data as a specific frame sequence. Then, we design a color code-based 4-point block pattern, that is inserted into the four vertices of the transmitted image frames. This block pattern enables frame-to-frame synchronization and accurate extraction of the data-embedded region from the received frames. Our proposed Video-DFC approach demonstrates the potential of transmitting a large amount of data and achieving a data transfer by embedding distinct data in each frame of the running video. To evaluate the robustness of Video-DFC, we conducted extensive experiments varying the frame packet structure, input video, and camera resolution. Depending on the frame packet structure, the results showed a maximum achievable data rate of $\mathrm {27~kbps}$ . Overall, our findings suggest that Video-DFC has the potential to be a next-generation, high-capacity D2C communication method.
Natural environment and its psychological effects: Exploring individuals' narratives

In recent years, several clinical syndromes have emerged, labeled as ecopsychopathologies, underlying the psychological relationship between individuals and natural environment. The aim of the present study was to analyze the nature of psychological distress related to this relationship administering to a sample of 20 participants: the Eco Psychopathologies Interview. The narratives elicited by this semi-structured interview were recorded and transcribed. The elementary context analysis, carried out with the T-Lab software, led to a two-factors and three-clusters solution. The interpretation process has identified the factors as Narrative of the personal story and Action. Three clusters have emerged, labeled Bonding, Transforming and Educating. As discussed, this qualitative data supports the idea that psychological distress emerging from the human relationship with the natural environment is a matter of identity, personal values and attachment to place.
Parallel Neural Network Structures for Signal-to-Noise Ratio Estimation in Optical Fiber Communication Systems

This paper proposes two novel neural network (NN) structures to estimate long-term steady linear and nonlinear signal-to-noise ratio (SNR) components in optical fiber communication systems. The first proposed structure is a parallel NN-based (ParNN) estimator, which estimates each SNR component using a different NN structure and input feature set. A combination of gated recurrent unit and dense layers is used to estimate the linear SNR component. On the other hand, the nonlinear SNR component is estimated using a combination of convolutional layer with dense layer. The proposed input features of the ParNN estimator are generated solely from the received signal without knowledge of the transmitted signal. These features are formed of the lower quartile, upper quartile, and entropy, which can accurately characterize the behavior of the SNR components by measuring the received signal spread and uncertainty. For further improvement of the ParNN estimator, an additional stage is added to form the proposed enhanced ParNN (EParNN) estimator. This additional stage consists of two feedforward NNs (FFNNs), each with a single dense layer, where the first FFNN is used to estimate the linear SNR component and the second one estimates the nonlinear SNR component. The input of this additional stage is a combination of the input features and output of the ParNN estimator. The computational complexity is derived for the proposed estimators. The training and testing dataset is built from 16-ary quadrature amplitude modulation of a dual-polarization on a wide range of standard single-mode fiber system configurations, e.g., number of wavelength division multiplexing channels, optical launch power, and number of spans. Numerical results demonstrate that the proposed ParNN estimator achieves better SNR estimation accuracy with comparable computational complexity compared to the most efficient work in the literature. The proposed ParNN estimator can independently estimate each SNR component, in which the complexity per SNR component is reduced. Moreover, the proposed EParNN estimator improves SNR estimation accuracy compared to the ParNN estimator at the expense of a slight increase in the computational complexity.
The ability of cover crops to reduce nitrogen and phosphorus losses from arable land in southern Scandinavia and Finland

This review summarizes current knowledge from the literature and experimental studies on the role of cover crops (CCs) in reducing nitrogen (N) leaching and phosphorus (P) losses to waters under the marine and humid continental climate conditions of southern Scandinavia and Finland. Field leaching studies from 11 sites indicate that undersown ryegrass (Lolium spp.) CCs are robust, with average N uptake in aboveground CC biomass of 7 to 38 kg N ha−1 (6.2 to 34 lb N ac−1). Use of CCs sown at harvest (e.g., crucifers) is restricted to southern Scandinavia for climate reasons. The mean relative reduction in N leaching reported for all CCs investigated was 43%, but it ranged between 62% increase instead of a reduction after a red clover (Trifolium pratense) CC on a clay soil to a reduction of 85% to 89% with a perennial ryegrass CC on sandy soils in Denmark (36 to 51 kg ha−1 [32 to 46 lb ac−1]). The data indicate that CCs do not substantially reduce total P losses by runoff and leaching. The effects of CCs on total P leaching varied between a relative increase of 86% and a decrease of 43%. Climate conditions involving freezing-thawing during winter increased the risk of losses of dissolved P from CC biomass. CCs have been implemented to varying degrees into agri-environmental programs. They are mandatory in Denmark and subsidized in Norway, Sweden, and Finland. CCs are grown on 8% of arable land in Denmark, 5% in Sweden, 1% in Finland, and 0.5% in Norway, but CC area is now increasing dramatically in Finland due to a new subsidy program. In all countries there is a need, and potential, for increased use of CCs, but there are several constraints, particularly reduced interest among farmers. There is a clear need to identify CC systems and develop implementation strategies for appropriate distribution of CCs on different soils and regions with respect to required reductions in N leaching and P losses. For this, more knowledge is required, especially about the effect of CCs on P losses (e.g., the effect of species with different partitioning between shoot and root biomass and the effects of CC systems with harvesting of biomass). There is also a need to devise balanced solutions for maintaining and increasing the frequency of CCs in crop rotations to exploit the possible benefits of CCs in reducing nutrient losses.
Observations of the far ultraviolet airglow by the Ultraviolet Limb Imaging Experiment on STS-39

The Ultraviolet Limb Imaging (UVLIM) experiment flew on STS-39 in the spring of 1991 to observe the Earth's thermospheric airglow and included a far ultraviolet (1080-1800 A) spectrometer. We present first results from this spectrometer, including a spectroscopic analysis at 6-A resolution of H, O, N, and N2 day glow emissions and modeling of the observed limb-scan profiles of dayglow emissions. The observed N2 Lyman-Birge-Hopfield (LBH) emission reflects a vibrational population distribution in the a¹Πg state that differs significantly from those predicted for direct electron excitation and excitation with cascade from the a′ ¹Σu− and w ¹Δu states. The Vibrational population distribution and LBH brightnesses suggest a total cascade rate 45% that of direct excitation, in contrast to laboratory measurements. For the first time, pronounced limb brightening is observed in both the N I λ1135 and N I λ1200 limb emission profiles, as expected for emissions excited by N2 dissociation which produces kinetically fast N fragments; however, optically thick components of these features are also observed. Preliminary modeling of the O I λ1356, H I λ1216, and O I λ1304 and O I λ1641 emissions agrees to within roughly 10% of the observed limb-scan profiles, but the models underestimate the N2 LBH profiles by a factor of 1.4-1.6, consistent with the inferred cascade effect. Other findings include: an O I λ1152/λ1356 intensity ratio that is inconsistent with the large cascade contribution to O I λ1356 from np 5P states required by laboratory and nightglow observations; nightglow observations of the tropical ultraviolet arcs exhibit a wide range of O I λ1356/λ1304 intensity ratios and illustrate the complicated observing geometry and radiative transfer effects that must be modeled; and we find a 3-σ upper limit of 8.5 R to the total LBH vehicle glow emission.
MAP3K19 Affects TWEAK-Induced Response in Cultured Bronchial Epithelial Cells and Regulates Allergic Airway Inflammation in an Asthma Murine Model

The mitogen-activated protein kinase (MAPK) signaling pathway is involved in the epithelial–mesenchymal transition (EMT) and asthma; however, the role of mitogen-activated protein kinase kinase kinase 19 (MAP3K19) remains uncertain. Therefore, we investigated the involvement of MAP3K19 in in vitro EMT and ovalbumin (OVA)-induced asthma murine models. The involvement of MAP3K19 in the EMT and the production of cytokines and chemokines were analyzed using a cultured bronchial epithelial cell line, BEAS-2B, in which MAP3K19 was knocked down using small interfering RNA. We also evaluated the involvement of MAP3K19 in the OVA-induced asthma murine model using Map3k19-deficient (MAP3K19−/−) mice. Transforming growth factor beta 1 (TGF-β1) and tumor necrosis factor-like weak inducer of apoptosis (TWEAK) induced the MAP3K19 messenger RNA (mRNA) expression in the BEAS-2B cells. The knockdown of MAP3K19 enhanced the reduction in E-cadherin mRNA and the production of regulated upon activation normal T cell express sequence (RANTES) via stimulation with TWEAK alone or with the combination of TGF-β1 and TWEAK. Furthermore, the expression of MAP3K19 mRNA was upregulated in both the lungs and tracheas of the mice in the OVA-induced asthma murine model. The MAP3K19−/− mice exhibited worsened eosinophilic inflammation and an increased production of RANTES in the airway epithelium compared with the wild-type mice. These findings indicate that MAP3K19 suppressed the TWEAK-stimulated airway epithelial response, including adhesion factor attenuation and RANTES production, and suppressed allergic airway inflammation in an asthma mouse model, suggesting that MAP3K19 regulates allergic airway inflammation in patients with asthma.
In-situ atomic-scale observation of dislocation and deformation twin interaction in FeMnCoCr high-entropy alloy

The deformation of a single-crystal Fe48Mn32Co10Cr10 alloy is captured in situ at the atomic scale. The results show that full and partial dislocations, along with deformation twins, are involved in the deformation process. Partial dislocation activities result in the formation of nanotwins, high-density coherent twin boundaries, and incoherent twin boundaries. Full dislocations interact with the coherent/incoherent twin boundaries, and partial dislocations, thereby producing high strength and remarkable strain hardening. The observed high activity of full dislocations can be attributed to the inhomogeneous distribution of solid solution atoms in the alloy. GRAPHICAL ABSTRACT
The Southern Mountains Zone, Isle of Rum, Scotland: volcanic and sedimentary processes upon an uplifted and subsided magma chamber roof

Abstract The Southern Mountains Zone of the Rum Central Complex lies inside a major ring fault and comprises an intricate association of country-rock outcrops, breccias and rhyodacite. The breccias and rhyodacite were long thought to be products of subterranean explosion and intrusion, respectively. Here, we report new observations that support re-interpretation of these units as mass movement deposits and ignimbrites. The most abundant breccias (Coire Dubh-type) consist mainly of country-rock clasts <1 m in diameter in a sand or silt matrix. Internally bedded and graded, and interlayered with sandstones and lithic tuffs, these breccias are interpreted as debris flow and stream flow deposits. Rhyodacite sheets show gradational or sharp, concordant contacts with Coire Dubh-type breccias, and display graded basal lithic tuffs and graded fiamme swarms. These sheets are interpreted as moderately to densely welded rhyodacite ignimbrites (25–100 m thick). A steep body of fragmented (fiamme-bearing) rhyodacite with intrusive non-fragmented contacts is interpreted as an ignimbrite vent system. The rhyodacite and breccia succession is over 200 m thick and unconformably overlies a structurally uplifted Precambrian basement, within which there is also evidence of later subsidence. Outcrops of potential caldera-collapse ‘megabreccia’ are more structurally consistent than previously thought, and are re-interpreted here as coherent segments of Precambrian country rock (caldera floor). The Southern Mountains Zone breccias and rhyodacites respectively reflect sedimentary and pyroclastic processes acting in response to a complex tectonic interplay of intrusion-related uplift and caldera subsidence.
Quatre nouveaux Chaetognathes atlantiques abyssaux (genre Heterokrohnia): description, remarques éthologiques et biogéographiques

INTRODUCTION Jean-Paul CASANOVA Laboratoire de Biologie animale (Plancton), Universite de Provence, 13331 Marseille Cedex 3, France. Recu le 14/10/85, revise le 22/5/86, accepte le 23/5/86. Des recoltes de plancton a proximite du fond (pres de 4000 rn) sur une station de l'Atlantique nord-africain ont ramene quatre especes nouvelles du genre Heterokrohnia, qui se revelent ainsi etre bentho-planctoniques abyssales. Elles font l'objet d'une description detaillee, notamment de l'appareil genital, qui, archaique, est tout a fait original au sein du phylum des Chaetognathes. Les observations sur le regime alimentaire de ces Heterokrohnia montrent que, si leur armature cephalique leur permet de capturer des proies a l'instar des autres genres de Chaetognates, elles peuvent aussi etre limivores, comme l'indique l'examen du contenu de leur tube digestif; cet opportunisme est peut-etre du a la rarete des proies dans leur habitat. Enfin, l'etude morphologique de deux de ces especes montre que, d'une part, la variete specifique est plus grande a proximite du fond que dans les couches d'eau sus-jacentes, ou s'observent des formes ubiquistes; d'autre part, cette variete est peut-etre plus grande dans les regions tropicales que dans l'Antarctique. Oceanol. Acta, 1986, 9, 4, 469-477. Four new abyssal Atlantic Chaetognaths (genus Heterokrohnia): description and ethological and biogeographical discussions In plankton sampled from near the bottom (about 4000 rn) in the North-African Atlantic, and consequently defined as abyssal bentho-planktonic, four new species of Heterokrohnia, were found. A detailed description is given, with special focus on the genital apparatus which is primitive and most unusual for Chaetognatha. With regard to the diet of these Heterokrohnia, it was observed that white they are· endowed with a head armature allowing them to prey like the other genera of Chaetognatha, they are also sediment-feeders as shown by the content of their digestive tract. This duality is perhaps caused by the scarcity of preys in their habitat. Lastly, a morphological study of two of these species shows that specifie diversity is greater near the bottom than in overlaying waters where ubiquitous forms are observed, and that this diversity may be greater in tropical than antarctic regions. Oceanol. Acta, 1986, 9, 4, 469-477. Quatre nouvelles especes du genre Heterokrohnia figurent dans les prelevements a differents niveaux dans les 1000 premiers metres au-dessus du fond (0-20, 20-100, 100-500, 500-1000 rn) sur la station 9541 du N.O. « Discovery » au large du Cap Blanc de Mauritanie (20°N-21 °W, 17-23 avril1977), ou des peches verticales ont ete effectuees entre 4000 rn et la surface avec des filets RMTl et RMT8.

Mixed connective tissue and ovarian cancer: a case report

Background: Mixed connective tissue disease (MCTD) is characterized by high titres of distinct antibodies: U1 ribonucleoprotein with variable clinical features seen in rheumatoid arthritis, systemic lupus erythematosus, scleroderma, polymyositis, and dermatomyositis. Limited case reports revealed the association between MCTD and cancer, like lymphoma, lung cancers, and others. Case presentation: A 22-year-old female presented with enlargement of the abdomen and oedema of the lower extremities, gradually started 25 days The patient had been diagnosed to have rheumatoid arthritis. She was treated with 7.5 mg/week MTX for 6 months. Physical examination revealed: pallor, lower limb oedema, with synovitis and deformities of hands. The laboratory tests showed anaemia, elevated levels of creatine phosphokinase ESR, positivity of antinuclear antibody, anti-ds DNA, and antinuclear ribonucleoprotein. Urinary protein excretion was 1625 mg/24 h. Chest X-ray showed bilateral pleural effusion. Echocardiography revealed pericardial effusion Thoracic-abdominal and pelvic tomography showed a heterogeneous mass with a diameter of 5 × 6 cm at the expense of the right ovary. The mass was removed surgically, and a biopsy was taken, and was compatible with ovarian high-grade serous adenocarcinoma. A course of solumedrol 1 g/IV/3 days was applied, and then continue with 60 mg/day oral predlone. Later on discharge, she was taken 25 mg/day predlone, and methotrexate 10 mg. Conclusions: Our case showed that the patient had no risk factors for developing ovary cancer. On the contrary, our patient was a young, non-smoker, without any previous treatment before the RA diagnosis was taken, and finally, she had 3 children with full-term pregnancy, and well health. This case highlights the importance of maintaining a high index of suspicion for malignancy in MCTD patients. However, further investigation on the role of the immune system in the development of ovarian cancer in women with autoimmune diseases including MCTD remains necessary.
Investigating Sex-Based Neural Differences in Autism and Their Extended Reality Intervention Implications

Autism Spectrum Disorder (ASD) affects millions of individuals worldwide, and there is growing interest in the use of extended reality (XR) technologies for intervention. Despite the promising potential of XR interventions, there remain gaps in our understanding of the neurobiological mechanisms underlying ASD, particularly in relation to sex-based differences. This scoping review synthesizes the current research on brain activity patterns in ASD, emphasizing the implications for XR interventions and neurofeedback therapy. We examine the brain regions commonly affected by ASD, the potential benefits and drawbacks of XR technologies, and the implications of sex-specific differences for designing effective interventions. Our findings underscore the need for ongoing research into the neurobiological underpinnings of ASD and sex-based differences, as well as the importance of developing tailored interventions that consider the unique needs and experiences of autistic individuals.
