The Essence of Foreign Language Learning in Today’s Globalizing World: Benefits and Hindrances

This paper highlights the essence of foreign language learning in today’s globalizing world as well as underscores its benefits and hindrances. It emphasizes that foreign language does collectively bind us together as human beings predicated upon our irresistible interdependence in various ways. Rationally speaking, being knowledgeable of a second or foreign language is extremely pertinent because it provides numerous life time opportunities. Yielding the dividends of studying abroad, employment, personal development, security, political and economic benefits among others make foreign language learning absolutely beneficial. Consequently, this paper sees foreign language conversance as a key that could unlock the door of your life and it must not be ignored. However, despite its overarching benefits, foreign language learning is continually constrained with the challenges of complexity, ignorance of its importance, learner-native speaker gaps, weak policies and inadequate support. Some of these challenges are related to the constructs of motivational beliefs and strategies which are vital to foreign language learning because learners must believe in themselves, value tasks and use appropriate strategies if they are to succeed. Finally, it recommends a collective concerted effort against monolingualism, but supports the formulation of salient policies and programs including the inclusion of foreign languages in the curricula, increased financial and moral supports, and early teaching of foreign languages to kids. Key words: foreign language, language benefits and barriers, motivational beliefs, language learning strategies, globalizing world

Effects of Parental Autonomy Support and Teacher Support on Middle School Students’ Homework Effort: Homework Autonomous Motivation as Mediator

The present study tested whether students’ autonomous motivation mediated the association between adult support (parental autonomy support, teacher support) and students’ homework effort. A sample of 666 Chinese middle school students was recruited to complete the parental autonomy support questionnaire, teacher support questionnaire, homework autonomous motivation questionnaire and homework effort questionnaire. Structural equation modeling showed that both parental autonomy support and teacher support positively predicted mathematics homework effort, and mathematics homework autonomous motivation was a mediator in these associations. The present study reveals the importance of adult support and autonomous motivation, and has theoretical and practical implications

Beetroot (<i>Beta vulgaris</i>) Extract against <i>Salmonella</i> Typhimurium via Apoptosis-Like Death and Its Potential for Application in Cooked Pork

Salmonella Typhimurium is a common foodborne pathogen in meat and meat products, causing significant harm and losses to producers and consumers. The aim of this study was to investigate the antibacterial activity and possible mechanisms of beetroot (Beta vulgaris) extract against S. Typhimurium, as well as the application potential in cooked pork. The results suggested beetroot extract could inhibit S. Typhimurium with a minimum inhibitory concentration (MIC) of 20 mg/mL. After treatment with beetroot extract (1 or 2 MIC), S. Typhimurium exhibited the characteristics of apoptotic-like death (ALD), such as membrane depolarization, phosphatidylserine (PS) externalization, caspase-like protein activation, and DNA fragmentation. Further research has shown that the ALD induced by beetroot extract in S. Typhimurium was caused by reactive oxygen species (ROS) consumption, which was different from most natural products. The treatment of cooked pork with beetroot extract could reduce the number of S. Typhimurium, lower pH, defer lipid oxidation, and improve the colour. These results indicate that beetroot extract can inhibit S. Typhimurium through the ALD mechanism and has potential as an antibacterial agent against S. Typhimurium in ready-to-eat meat products

Structural and Emulsifying Properties of Soybean Protein Isolate–Sodium Alginate Conjugates under High Hydrostatic Pressure

Soybean protein isolate (SPI) is a kind of plant derived protein with high nutritional value, but it is underutilized due to its structural limitations and poor functionalities. This study aimed to investigate the effects of high hydrostatic pressure (HHP) treatment on SPI and sodium alginate (SA) conjugates prepared through the Maillard reaction. The physicochemical properties of the conjugate synthesized under 200 MPa at 60 °C for 24 h (SPI–SA–200) were compared with those of the conjugate synthesized under atmospheric pressure (SPI–SA–0.1), SPI-SA mixture, and SPI. The HHP (200 MPa) significantly hindered the Maillard reaction. This effect was confirmed by performing SDS-PAGE. The alterations in the secondary structures, such as α-helices, were analyzed using circular dichroism spectroscopy and the fluorescence intensity was determined. Emulsifying activity and stability indices of SPI-SA-200 increased by 33.56% and 31.96% respectively in comparison with the SPI–SA–0.1 conjugate. Furthermore, reduced particle sizes (356.18 nm), enhanced zeta potential (‒40.95 mV), and homogeneous droplet sizes were observed for the SPI-SA-200 emulsion. The present study details a practical method to prepare desirable emulsifiers for food processing by controlling the Maillard reaction and improving the functionality of SPI

Benefits of prompting students to generate summaries during pauses in segmented multimedia lessons

Background: How to improve learning with online multimedia lessons has attracted widespread concern. Prior studies have attempted to help students learn by breaking a video lesson into several segments. However, there has been a debate about whether learners can use pause time effectively and whether prompting them to engage in different types of generative learning activities during pauses can better facilitate learning. Objectives: This study aimed to explore how to maximize learning by asking students to engage in generative processing activities during pauses in segmented narrated video lessons. Methods: Three experiments explored the effectiveness of segmenting, and whether adding summaries between segments can improve learning performance. In Experiment 1, participants were asked to view a segmented video or a continuous video. In Experiment 2, we examined whether adding summarizing activities during pauses can improve the effects of segmenting. In Experiment 3, we further investigated the effects of adding different types of summarizing activities during pauses. Results and Conclusions: In Experiment 1, segmenting improved performance on retention tests, but not on transfer tests. In Experiment 2, the effects of segmenting on the retention and transfer tests were enhanced when learners were asked to produce written summaries during the pauses. In Experiment 3, asking participants to imagine or write summaries during the pauses in segmented lessons improved retention and transfer test performance, but providing a summary only helped on retention. Takeaways: Adding generative learning activities (i.e., summarizing) during pauses prompted learners to learn the material more deeply. Results are consistent with the ICAP framework and the cognitive theory of multimedia learning

Delay-CJ: A novel cryptojacking covert attack method based on delayed strategy and its detection

Cryptojacking is a type of resource embezzlement attack, wherein an attacker secretly executes the cryptocurrency mining program in the target host to gain profits. It has been common since 2017, and in fact, it once became the greatest threat to network security. To better prove the attack ability the harm caused by cryptojacking, this paper proposes a new covert browser-based mining attack model named Delay-CJ, this model was deployed in a simulation environment for evaluation. Based on the general framework of cryptojacking, Delay-CJ adds hybrid evasion detection techniques and applies the delayed execution strategy specifically for video websites in the prototype implementation. The results show that the existing detection methods used for testing may become invalid as result of this model. In view of this situation, to achieve a more general and robust detection scheme, we built a cryptojacking detection system named CJDetector, which is based on cryptojacking process features. Specifically, it identifies malicious mining by monitoring CPU usage and analyzing the function call information. This system not only effectively detects the attack in our example but also has universal applicability. The recognition accuracy of CJDetector reaches 99.33%. Finally, we tested the web pages in Alexa 50K websites to investigate cryptojacking activity in the real network. We found that although cryptojacking is indeed on the decline, it remains a part of network security threats that cannot be ignored

Geological features, controlling factors and potential prospects of the gas hydrate occurrence in the east part of the Pearl River Mouth Basin, South China Sea

Logging-while-drilling (LWD) and wireline log (CWL) data were acquired during China's second gas hydrate drilling expedition (GMGS-2) in the east of Pearl River Mouth Basin, South China Sea. Disseminated and massive gas hydrates deposits were found at different sites. Gas hydrate-bearing lithologies identified from the sample coring included the fine-grained sediments and coarse-grained sediments. LWD logs from Site GMGS2-08 indicate significant gas hydrate in clay-bearing sediments including two layers with massive gas hydrate with a bulk density near to 1.08 g/cm3. High electrical resistivities with a range of 2.5–2000.0 Ω m and high P-wave velocities are simultaneously observed in the hydrate-bearing sediments. The average gas hydrate saturation estimated from the pore water freshing analysis ranges from 45 to 55% of the pore space. Buried carbonate layers above the massive gas hydrate deposit discovered at Sites GMGS2-08 indicate that the formations are likely to have formed initially at the surface and then were buried. Significant high amplitude seismic anomalies, discontinuous bottom simulating reflection (BSR) and blanking zone are detected in the drilling zone. The hydrate-bearing sediments predominantly consist of silty clay and limestone grains in which the gas hydrates are deposited primarily in the form of laminated, massive, veins or nodule. The gas hydrates occurrences are subjected to the sediment lithology, new tectonic activities, migration of fluid and gas and also the factors such as heat flow, salinity and time which affect the nucleation of gas hydrates. Its natural morphologies present massive, laminated, nodular, nugget and disseminated, of which the former four often formed in shallow fault, inter-layer's weak cementation zone and on the seabed. The “buried” gas hydrates with high saturation are good zones for gas hydrate exploitation
