Multiple Roles of Grit in the Relationship Between Interpersonal Stress and Psychological Security of College Freshmen

Grit, as an important positive psychological quality, has rarely been studied for its role involved in the mechanism between stress and psychological security. This article explores the moderating and mediating role of grit in the relationship between interpersonal stress and psychological security of freshmen through two studies. In study 1, freshmen from several Chinese universities (N = 1,224) were recruited to complete a battery of questionnaire, including assessments about interpersonal stress, grit, and psychological security. The moderating effect analysis showed that grit moderated the relationship between interpersonal stress and psychological security. Specifically, grit buffered the negative effects of interpersonal stress on freshmen’s psychological security, but this effect was obvious only when the level of interpersonal stress was relatively low, and decreased when the level of interpersonal stress was high. In study 2, college freshmen from another university apart from above ones (N = 604) were recruited, and we verified the results of study 1 and further explored the mediating role of grit in the relationship between interpersonal stress and security. The moderating effect analysis of study 2 also verified that of study 1. The mediating effect analysis showed that interpersonal stress not only negatively predicted psychological security, but also affected psychological security through the mediation of grit. In general, grit played a mediating and moderating role in the relationship between interpersonal stress and psychological security. This study provides first-hand evidence to explain the multiple roles of grit in the relationship between interpersonal stress and psychological security.
The Geochemical Study of Oil-Oil and Oil-Source Rock Correlations in the Wushi Sag of the Beibu Gulf Basin, South China Sea

Chemometrics has been widely used to cope with the problems of oil-oil and oil-source correlations because of its unique advantages in the comprehensive consideration of multiple parameters and the classification of samples or variables. In this paper, three chemometric methods, especially multidimensional scaling, were used to revisit the genetic oil family and the relationship between the crude oil and the source rock, because the oil source in the Wushi Sag, a significant petroliferous sag in the Beibu Gulf Basin of South China Sea, is still controversial. Two genetic families of crude oils, namely group A and group B, have been identified based on chemometric results. Group A oils are characterized by relatively higher Pr/Ph ratios and a high abundance of C27 ααα 20R steranes and C30-methylsteranes than those of group B oils, suggesting that this group of oils was deposited under a more oxic condition with more contribution of algae organic matter. Group A oils have been interpreted to be a mixture derived from the member 2 and member 3 of the Liushagang Formation (LS-2 and LS-3), whereas group B oils can be ascribed to the LS-2 member. The contribution of LS-3 mudstone member to the Wushi oils in previous studies may have been underestimated to some extent, which was inferred from the chemometric oil-source correlation results. The results of oil-source rock correlation may be used to guide future petroleum exploration activities with the incorporation of geological evidence. The spatial distribution of oil and gas reservoirs varies with burial depth. Taking into consideration other geological evidence, we may infer that the reservoir in eastern Wushi Sag was mainly distributed in the deep of Liushagang Formation, whereas the reservoir in southeast Wushi Sag was likely located in the shallow Liushagang Formation.
CFD Simulation of Flow around External Vehicle: Ahmed Body

The main objective of this paper is to elucidate a solution to reduce the inefficiencies and losses caused due to major parameters pertaining to the aerodynamics of road vehicle (drag, lift). This is accomplished by investigating the variation of the rear slant angle of the Ahmed body and its effect on the drag and lift coefficients and determine the optimum angle for least drag through numerical simulation. The simplified vehicle geometry: Ahmed Reference Model has been used as a benchmark. The computational part consists of numerical simulation of the flow around the Ahmedbody employing CFD (Computational Fluid Dynamics) techniques. In numerical simulation results, pressure-based solver was utilized and the turbulence model employed was k-Epsilon realizable model with non-equilibrium wall function for near wall treatment. The designing of model used in this paper is done through the SOLIDWORKS '14; and CFD simulation carried out in FLUENT (ANSYS 14).

UNUSED LANDSCAPE DETECTION FROM SATELLITE IMAGE USING DEEP LEARNING: A Review

: - As the landscapes changes day by day it leads to the increasing use of unused lands, by which unused lands can be used for various purposes like agriculture, developing city infrastructure and many more. Here remote sensing earth images are taken as the dataset where the pre-processing step includes converting image into greyscale image, compression and noise removal. Segmentation is done to partition the region of used and unused lands. Feature extraction is done here using local binary feature extraction in-order to identify edge, flat and corner surfaces. As the mentioned various algorithm is used in classification and labeling of remote sensing earth images. CNN algorithm is also used for classification and labeling of classification is done automatically by the use of CNN algorithm. Random forest is used to segregate two landscapes as used and unused land which gives accuracy better than the existing systems
Slips of the Tongue and Repair Strategies in TV Show “Tonight Show Indonesia”

The most common mistake in daily conversation is speech errors, and one of them caused by slip of the tongue. This study aimed to discover types of repair strategy in slips of the tongue which came from the speaker in the “Tonight Show Indonesia”. This study used a descriptive qualitative design, and data were taken from the transcriptions of seven YouTube videos of “Tonight Show Indonesia” that contained slips of the tongue and repairs in the conversations. To analyze the slips of the tongue and repairs, researchers used psycholinguistics approach and conversation analysis theory. This study analyzed the slips of the tongue based on Wells (1951), Hockett (1967), Fromkin (1971) and repairs in the conversation from Schegloff, Jefferson, and Sacks (1977). The results showed that there were six out seven types of slips of the tongue occurred in the conversations, namely anticipation, preservation, transpositions, substitutions, blends, counter blends, and haplologies. The most dominant type was substitutions. The results also showed that the slips of the tongue appeared in the conversations with different types of repairs. The speaker used self-initiated selfrepair more frequently than other types of repair strategy in the conversations.
Hiring, separations, vacancies and productivity

We study empirically and theoretically the flows of workers across firms of different productivity and the hiring effort of these firms. We combine four datasets from Denmark with very detailed information on workers, firms and vacancies posted. Using the data, we derive the patterns of hiring, separations and vacancy posting for firms of different productivity levels. We observe that some of the patterns are not fully consistent with the simple job-ladder model and propose a parsimonious theoretical model that can capture these patterns.
Hybrid Nanoparticles and Composite Hydrogel Systems for Delivery of Peptide Antibiotics

The growing number of drug-resistant pathogenic bacteria poses a global threat to human health. For this reason, the search for ways to enhance the antibacterial activity of existing antibiotics is now an urgent medical task. The aim of this study was to develop novel delivery systems for polymyxins to improve their antimicrobial properties against various infections. For this, hybrid core–shell nanoparticles, consisting of silver core and a poly(glutamic acid) shell capable of polymyxin binding, were developed and carefully investigated. Characterization of the hybrid nanoparticles revealed a hydrodynamic diameter of approximately 100 nm and a negative electrokinetic potential. The nanoparticles demonstrated a lack of cytotoxicity, a low uptake by macrophages, and their own antimicrobial activity. Drug loading and loading efficacy were determined for both polymyxin B and E, and the maximal loaded value with an appropriate size of the delivery systems was 450 µg/mg of nanoparticles. Composite materials based on agarose hydrogel were prepared, containing both the loaded hybrid systems and free antibiotics. The features of polymyxin release from the hybrid nanoparticles and the composite materials were studied, and the mechanisms of release were analyzed using different theoretical models. The antibacterial activity against Pseudomonas aeruginosa was evaluated for both the polymyxin hybrid and the composite delivery systems. All tested samples inhibited bacterial growth. The minimal inhibitory concentrations of the polymyxin B hybrid delivery system demonstrated a synergistic effect when compared with either the antibiotic or the silver nanoparticles alone.

Quantifying Spatial Drought Propagation Potential in North America Using Complex Network Theory

Droughts have a dominant three‐dimensional (3‐D) spatiotemporal structure typically spanning hundreds of kilometers and often lasting for months to years. Here, we introduced a novel framework to explore the 3‐D structure of the evolution of droughts based on network theory concepts. The proposed framework is applied to identify critical source regions responsible for large‐scale drought onsets during 1901–2014 for the North American continent using the Standardized Precipitation Evaporation Index (SPEI). We built a spatial network connecting the drought onset timings for the North American continent. Using a spatially weighted network partitioning algorithm, the whole continent is then classified into regional spatial drought networks (RSN), where droughts are more likely to propagate within these regional systems. Finally, a customized network metric was applied to identify locations (source regions) where the drought onsets further propagate to other areas within the regional spatial network. Our results indicated that the West coast, Texas coastal region, and Southeastern Arkansas as major source regions through which atmospheric drought propagates to Western, South Central, and Eastern North America. The formation of drought source regions are due to presence of high pressure ridges and anomalous wind patterns. Furthermore, our results indicate that the drought propagation from these source regions may be due to inadequate moisture transport. The proposed framework can help to develop an early warning detection system for droughts and other spatially extensive extreme events such as heatwaves and floods.
Analysis of Impact of Bottom Electrode Position on Dynamic Pull-In Parameters of Microcantilevers

The stable range of MEMS electrostatically actuated beam during the pull-in process is crucial to the device performance. Different devices have specific requirements for stable pull-in region based on their applications. In this paper, Rayleigh-Ritz energy method is used to establish dynamic pull-in model of electrostatic cantilever actuated by a step voltage. Modified trial function is derived according to different position of bottom electrode. The model takes into account the effects of fringe capacitance and variable cross-sectional beam. Published numerical methods and experimental data are used to verify the model . The impact of bottom electrode position on pull-in parameters is analyzed in present model. With fitting empirical equations, pull-in parameters can be easily satisfied through the distribution of bottom electrode, which provide an effective reference for the design of MEMS electrostatically actuated beam under given pull-in parameters .
Vocabulary Teaching Practices of L2 English in Upper Secondary Vocational Classrooms

This qualitative study investigates language teaching practices relating to L2 English vocabulary instruction in upper secondary school vocational classrooms in Norway. It builds on previous research describing technical vocabulary as an area of particular importance for vocational students’ English language development and relies on observation data from eight vocational classrooms. The study found that vocabulary work has a strong presence within vocational orientation (VO) instruction, across whole-class instruction, group or pair work, and individual work. Most target vocabulary could be classified as words relating to work practices and vocational content knowledge. Many instances of L1–L2 translation tasks were observed. Target words were not practiced across the four language skills and were rarely utilized in productive tasks. The study concludes that observed practices can be improved by prioritizing ways of combining target vocabulary with students’ language production and by including more opportunities to practice independent language strategies.
Not…Until across European Languages: A Parallel Corpus Study

We present a parallel corpus study on the expression of the temporal construction ‘not…until’ in a sample of European languages. We use data from the Europarl corpus and create semantic maps by multidimensional scaling, in order to analyze cross-linguistic and language-internal variation. This paper builds on formal semantic and typological work, extending it by including conditional constructions, as well as connectives of the type as long as. In an investigation of 7 languages, we find that (i) languages use many more different constructions to convey this meaning than was expected from the literature; and (ii) the combination of polarity marking (negation/assertion) strongly correlates with the type of connective. We corroborate our results in a larger sample of 21 European languages. An analysis of clusters and dimensions of the semantic maps based on the enlarged dataset shows that connectives are not randomly distributed across the semantic space of the ‘not…until’-domain.
Kapwa child participation, kapwa childhood, and a path towards the indigenisation and expansion of international agreements

ABSTRACT The Philippines has championed child participation from the drafting of the United Nations Convention on the Rights of the Child (CRC) to the creation of child participation structures in domestic and regional intergovernmental governance. This has been possible because the country has strong anchors that ground CRC in the country. We explore one such anchor, kapwa, a Filipino equivalent for the Western ‘other’ but means more as ‘shared self’ or ‘together with the person’ and identified as a core Filipino value and/or virtue ethics. Using a model of social ontology, we turn this anchor into a ground of child participation. In a kapwa ground, child participation expands from the communicative processes the CRC confines it to social engagements; from fixed and hierarchical child-adult roles to negotiated and interdependent roles. Kapwa child participation also gives way to a kapwa childhood construct that can integrate the diverse Filipino childhood constructs, a construct that acknowledges children’s vulnerability and need of protection as it acknowledges their equality with adults; children are simultaneously human beings and ‘becomings’. In this paper, we present a path, which other investigators or practitioners can follow, to domesticate and to develop alternative local discourses that could enhance global agreements.
Efficacy and safety of ketamine in mechanically ventilated intensive care unit patients: a scoping review

Objectives: Mechanically ventilated patients account for about one-third of all admissions to the intensive care unit (ICU). Ketamine has been conditionally recommended to aid with analgesia in such patients, with low quality of evidence available to support this recommendation. We aimed to perform a narrative scoping review of the current knowledge of the use of ketamine, with a specific focus on mechanically ventilated ICU patients. Methods: We searched MEDLINE and EMBASE for relevant articles. Bibliographies of retrieved articles were examined for references of potential relevance. We included studies that described the use of ketamine for postoperative and emergency department management of pain and in the critically unwell, mechanically ventilated population. Results: There are few randomised controlled trials evaluating ketamine’s utility in the ICU. The evidence is predominantly retrospective and observational in nature and the results are heterogeneous. Available evidence is summarised in a descriptive manner, with a division made between high dose and low dose ketamine. Ketamine’s pharmacology and use as an analgesic agent outside of the ICU is briefly discussed, followed by evidence for use in the ICU setting, with particular emphasis on analgesia, sedation and intubation. Finally, data on adverse effects including delirium, coma, haemodynamic adverse effects, raised intracranial pressure, hypersalivation and laryngospasm are presented. Conclusions: Ketamine is used in mechanically ventilated ICU patients with several potentially positive clinical effects. However, it has a significant side effect profile, which may limit its use in these patients. The role of low dose ketamine infusion in mechanically ventilated ICU patients is not well studied and requires investigation in high quality, prospective randomised trials.
Favorable surgical outcomes and perioperative complication rates after robotic radical cystectomy and intracorporeal urinary diversion at a single, low-volume center: Initial experience with 65 consecutive cases

Purpose: This study aimed to evaluate the surgical outcomes and perioperative complications among patients who underwent robot-assisted radical cystectomy (RARC) with intracorporeal urinary diversion (ICUD). Methods & materials: We retrospectively reviewed the clinical and pathological records of 65 consecutive patients who underwent RARC with ICUD between November 2018 and June 2021 at Gifu University. The patients were divided into three groups according to the type of urinary diversion: ureterocutaneostomy (UC), ileal conduit (IC), and ileal neobladder (NB). The endpoints of this study were surgical outcomes and perioperative complications according to the type of UD. Results: There were no significant differences between the IC and NB groups with respect to the total operation time. Twenty-seven complications were registered in the first 90 days. The most frequent early complication was urinary tract infection in 11 patients. Conclusion: Our initial experience with RARC followed by ICUD was favorable, with acceptable surgical outcomes and perioperative complications.
CRC-Based Correction of Multiple Errors Using an Optimized Lookup Table

In this paper, we propose a new approach to perform multiple error correction in wireless communications over error-prone networks. It is based on the cyclic redundancy check syndrome, using an optimized lookup table that avoids performing arithmetic operations. This method is able to achieve the same correction performance as the state-of-the-art approaches while significantly reducing the computational complexity. The table is designed to allow multiple bit error correction simply by navigating within it. Its size is constant when considering more than two errors, which represents a tremendous advantage over earlier lookup table-based approaches. Simulation results of a C implementation performed on a Raspberry Pi 4 show that the proposed method is able to process single and double error corrections of large payloads in 100 ns and 642 μs, respectively, while it would take 300 μs and 1.5 s, respectively, with the state-of-the-art CRC multiple error correction technique. This represents a speedup of nearly 3000× for single error and 2300× for double error correction, respectively. Compared to table-based approaches, the proposed method offers a speedup of nearly 1200× for single error and 2300× for double error correction under the same conditions. We also show that when multiple candidate error patterns are present, numerous errors can be corrected by adding a checksum cross-validation step.
Trends in Ambulatory Analgesic Usage after Myocardial Infarction: A Nationwide Cross-Sectional Study of Real-World Data

Although current guidelines for myocardial infarction (MI) recommend caution in using non-steroidal anti-inflammatory drugs (NSAIDs), real-world studies of ambulatory settings are rare. This study aimed to explore the patterns and trends of analgesic prescriptions (especially NSAIDs) among patients with a history of MI in ambulatory care settings in Korea. We analyzed real-world data from the Korea National Health Insurance Service database. Patients aged 20 years or older hospitalized with incident MI were identified between January 2007 and December 2015. Ambulatory analgesics were administered after discharge from incident hospitalization for MI, and annual trends in the prescriptions of individual analgesics were evaluated. Among the 93,597 patients with incident MI, 75,131 (80.3%) received a total of 2,081,705 ambulatory analgesic prescriptions. Prescriptions were mainly issued at primary care clinics (80.3%). Analgesics were most frequently prescribed for musculoskeletal diseases (often NSAIDs, 70.7%); aceclofenac (13.7%) and diclofenac injection (9.4%) were the frequently used NSAIDs. Additionally, significant changes were observed in the trends for some analgesics, such as loxoprofen. This study suggested that NSAIDs are commonly prescribed to patients with a history of MI. Future real-world studies are needed to elucidate the drug–disease interactions of NSAIDs prescribed after MI, especially for patients with musculoskeletal diseases.
