Leveraging Health Behavior and Communication Theories to Support Adolescent and Young Adults: Conceptualizing Social Media Wellness in Relation to Disordered Eating

Social media platforms like Instagram serve as an important mechanism for transmitting social information and influence. However, the nature and use of these platforms are known to perpetuate eating disorders (EDs) or further disorder eating symptoms. This concept paper proposes merging health behavior and communication theory to create a comprehensive and applicable framework for remediating pro-eating disorder social media content among people who have eating disorders. To this end, the Social Media Wellness Model, which is adapted from the Health Belief Model, the Uses and Gratifications approach, the MAIN model of media affordances, and media literacy training, is proposed. This paper shows how theoretical model components can be mapped back to behaviors typified by individuals with EDs, or those predisposed to developing EDs. Subsequently, we propose a training intervention to highlight salient literacy cues, and outline next steps for testing and developing this model with the ongoing support of a community advisory board (CAB). Creating a CAB with individuals who have lived experience of an ED or disordered eating, and who use social media, will be vital to testing the applicability of this conceptual Social Media Wellness Model for ED recovery.
Performance Assessment of an Energy–Based Approximation Method for the Dynamic Capacity of RC Frames Subjected to Sudden Column Removal Scenarios

The alternative load path method is widely used to assess the progressive collapse performance of reinforced concrete structures. As an alternative to an accurate non–linear dynamic analysis, an energy–based method (EBM) can also be adopted to approximately calculate the dynamic load–bearing capacity curve or the dynamic resistance based on a static capacity curve. However, dynamic effects cannot be explicitly taken into account in the EBM. The model uncertainty associated with the use of the EBM for evaluating the dynamic ultimate capacity of structural frames has not yet been quantified. Knowledge of this model uncertainty is however necessary when applying EBM as part of reliability calculations, for example, in relation to structural robustness quantification. Hence, this article focuses on the evaluation of the performance of the EBM and the quantification of its model uncertainty in the context of reliability–based assessments of progressive or disproportionate collapse. The influences of damping effects and different column removal scenarios are investigated. As a result, it is found that damping effects have a limited influence on the performance of the EBM. In the case of an external column removal scenario, the performance of the EBM is lower as the response is not a single deformation mode according to the results in the frequency domain. However, a good performance is found in the case of an internal column removal scenario in which the assumption of a single deformation mode is found to be sufficiently adequate. Probabilistic models for the model uncertainties related to the use of the EBM compared to direct dynamic analyses are proposed in relation to both the resistances and the associated displacements. Overall, the EBM shows to be an adequate approximation, resulting in a small bias and small standard deviation for its associated model uncertainty.
Learning Management System Usage among Undergraduates (Evidence from a Non-State University in Sri Lanka)

Because the ultimate purpose of using a learning management system is to improve effective learning, the system's benefits cannot be realized if students use it infrequently. To determine the elements that affect student usage, education providers must first understand how students view technology and their concerns. As a result, educational institutions must identify the primary elements impacting students' use of LMS and why students decide to use or reject LMS when given the option. This study aims to determine the factors that influence the use of Learning Management Systems by undergraduates at a Sri Lankan non-state university. There are three theories about how people use E-learning. There are three of them: TRA, TPB, and TAM. Because TRA and TPB have some limitations, this study used TAM. This study was expanded based on earlier research to include the variables: Subjective Norms, Internet and Computer Experience, Self-Efficacy, Technical Support, and Anxiety. At the specified university, there are 2128 students. The researcher collected data from 141 students by using Stratified random sampling techniques. Then the data was entered into a SmartPLS3. All measurement criteria for the measurement model's reliability and validity were fulfilled, and the structural model has fulfilled the Goodness of Fit. The results show that Self-Efficacy and Anxiety have a significant negative impact on the Perceived Ease of Use. Perceived Ease of Use has a significant negative impact on the Perceived Usefulness Self-Efficacy and Technical Support have a significant positive impact on the Perceived Usefulness Subjective Norms, and Perceived Usefulness have a significant positive impact on Intention to Use.
Antioxidant Activity of Palmitic Acid And Pinostrobin From Methanol Extract Of Syzygium litoralle (Myrtaceae)

This study presents a research of klampok watu plant (Syzygium littorale) including the Myrtaceae family. As far, only a few report about Syzygium littorale in leaves, fruit, stem bark or other parts. The stem bark of plant was extracted with an organic solvent and then fractionated (isolated) using standard chromatographic techniques. The molecular structure of pure isolates was elucidated and identified with spectroscopic evidence and compared to literature data and authentic sample. The dry powder of the stem bark was extracted with methanol and partitioned with chloroform and hexane, respectively. Isolation of the methanol fraction through vacuum liquid chromatography and followed by recrystallization which always monitored by TLC, yielded a pure compound. The identification result of pure compound showed there are palmitic acid and pinostrobin. The finding of the compounds from the plant is for the first time, although it have previously been found in other Syzygium plants, such as S. samarangense, S. cumini, S. polyanthum, S. polycephalum, etc. The methanol fraction, the isolated compounds palmitic acid, pinostrobin, and vitamin C showed antioxidant activity with IC50 value of 44.85; 189.9; 184.88, and 11.81 μg/mL, respectively. Keywords—antioxidant; klampok watu; palmitic acid; pinostrobin; methanol fraction; Syzygium littorale
Reanalysis Surface Mass Balance of the Greenland Ice Sheet Along K‐Transect (2000–2014)

Accurate estimates of surface mass balance over the Greenland ice sheet (GrIS) would contribute to understanding the cause of recent changes and would help to better estimate the future contribution of the GrIS to sea‐level rise. Given the limitations of in‐situ measurements, modeling, and remote sensing, it is critical to explore the opportunity to merge the available data to better characterize the spatial and temporal variation of the GrIS surface mass balance (SMB). This work utilizes a particle batch smoother data assimilation technique that yields SMB estimates that benefit from the snow model Crocus and a 16‐day albedo product derived from satellite remote sensing data. Comparison of the results against in‐situ SMB measurements shows that the assimilation of the albedo product reduces the root mean square error of the posterior estimates of SMB by 51% and reduces bias by 95%.
Artificial Insemination in Sheep with Fresh Diluted Semen: Comparison Between Two Different Semen Extenders and Management Protocols

Timed artificial insemination (TAI) is a very important tool for reproductive programs in small ruminants, providing synchronized inseminations and more efficient use of superior males. The objectives of this study were to investigate the viability of different breeding protocols under sub-optimal conditions and out of the breeding season, and to compare the outcome of TAI in sheep with two different semen extenders. Ewes (n=575) were subjected to estrous synchronization by intravaginal sponges containing 30 mg of medroxyprogesterone acetate and PMSG. Ewes were divided into 5 groups according to the semen extender employed and to the breeding protocol: 1) egg yolk citrate AI reinforced by ram (EYC-RR); 2) Andromed AI reinforced by ram (AND-RR), where rams joined the flocks 3 hours after AI; 3) egg yolk citrate AI without ram exposition (EYC); 4) Andromed AI without ram exposition (AND). In all these groups vaginal AIs were performed 56±2 hours from sponge removal and PMSG injection; 5) natural mating (RAM) where rams were introduced 48 hours following sponge removal and PMSG injection. Pregnancy rate, parturition rate, and prolificacy were significantly higher (p<0.05) in the EYC-RR and AND-RR groups than in the EYC and AND groups. The lambing rate was not different between groups. No statistical differences were observed between breeding farms or inseminating rams. This study showed that TAI with fresh semen diluted either with egg yolk citrate or with AndroMed could be an effective and feasible tool to increase lamb production and improve genetic merits of the sheep population out of the breeding season.
Genesis and Classification of Nitisols from Volcano-Sedimentary Lithology in Northeastern Brazil

ABSTRACT On the southern coast of Pernambuco State (PE), Brazil, lithotypes of the Cabo Basin (volcanic and sedimentary rocks), in association with the relief, allow the determination of the dynamics of the formation of Nitossolos Haplicos (Nitisols), including those with high levels of exchangeable aluminum. The objective of this study was to evaluate the influence of lithological diversity (basalt and sedimentary siliciclastic rocks) on the morphological, physical, chemical, and mineralogical properties of Nitossolos Haplicos along a slope (P1-summit, P2-backslope, P3-footslope) [. ]
Meaningful Work, Quality of Work-life, and Job Satisfaction: A Study of Nightlife Workers

Work is a means for man to fulfill their needs. However, from the positive psychology point of view, work is more than to fulfill the needs but beyond that reason. Work experiences provide added value to man’s lives and societal growth. Nightlife industries are hardly researched even though these industries have been growing vastly. Workers in these areas are similar to other workers from different types of industries in that they make meaning of their work and experience job satisfaction and quality of their work-life. This research aimed at testing the contribution of the quality of work-life and meaningful work toward job satisfaction of female nightlife business workers. Path analysis using PLS-SEM shows that the job satisfaction of nightlife workers is predicted by their meaningful work and quality of work life. In this study, meaningful work acts as a mediator in the relationship between quality of work-life and job satisfaction.
Individual Competencies for Self-Managing Team Performance: A Systematic Literature Review

Self-managing teams are popular but they can only benefit team performance if their members are competent to navigate within self-managing systems. Based on a systematic literature search on self-managing, self-directing, and self-leading teams, we reviewed 84 studies related to KSAOs and traits in self-managing teams. Grounded on existing models of team effectiveness and individual KSAOs, we integrated all findings into one KSAO model and showed the relations of single KSAOs with team performance. The results resembled other KSAO frameworks but were more comprehensive and provided practical application and future research guidance, for example, studying team compositions of individual KSAOs.

The present study contributes to the literature by increasing the accumulation of knowledge on research topics, providing an up-to-date review on hotel innovation literature, and setting forth an agenda for future research.
Comparison of N Mineralization Rate and Pattern in Different Manure- and Sewage Sludge-Amended Calcareous Soil

ABSTRACT A 12-week incubation experiment was conducted to determine the pattern and rate of N mineralized from organic materials. Treatments consisted of sheep manure (SM), cattle manure (CM), poultry manure (PM), sewage sludge (SS) at 1% (W/W) level, and unfertilized treatment with three replications. The concentrations of nitrate (NO3)- nitrogen (N) and ammonium (NH4)-N were determined in day 1 and 1, 2, 4, 8, and 12 weeks after the beginning of incubation. Results indicated that the magnitude of N mineralized during the incubation time periods was in the order of CM (134 mg kg−1) > PM (83 mg kg−1) > SS (56 mg kg−1) > SM (55 mg kg−1), and different management is required for obtaining optimum N-use efficiency. In conclusion, improving N-uptake efficiency in manure- and SS-amended soils depends on the pattern and rate of N mineralization to synchronize N released with crop N demand periods.
Optical Fiber Fabry–Perot Interferometer Based Spirometer: Design and Performance Evaluation

Spirometry enables the diagnosis and monitoring of multiple respiratory diseases, such as asthma and chronic obstructive pulmonary disease (COPD). In this paper, we present an optical fiber-based device to evaluate the pulmonary capacity of individuals through spirometry. The proposed system consists of an optical fiber containing an intrinsic Fabry–Perot interferometer (FPI) micro-cavity attached to a 3D printed structure that converts the air flow into strain variations to the optical fiber, modulating the FPI spectral response. Besides providing the value of the flow, its direction is also determined, which enables a differentiation between inhale and exhale cycles of breathing. A simulation study was conducted to predict the system behavior with the air flow. The preliminary tests, performed with the FPI-based spirometer led to average values of forced expiratory volume in 1 s (FEV1) and forced vital capacity (FVC) parameters of 4.40 L and 6.46 L, respectively, with an FEV1/FVC index (used as an airway function index) of 68.5%. An average value of 5.35 L/s was found for the peak expiratory flow (PEF). A comparison between the spirometry tests using the presented FPI system and a commercial electronic device showed that the proposed system is suitable to act as a reliable spirometer.
Data deprivations, data gaps and digital divides: Lessons from the COVID-19 pandemic

This paper draws lessons from the COVID-19 pandemic for the relationship between data-driven decision making and global development. The lessons are that (i) users should keep in mind the shifting value of data during a crisis, and the pitfalls its use can create; (ii) predictions carry costs in terms of inertia, overreaction and herding behaviour; (iii) data can be devalued by digital and data deluges; (iv) lack of interoperability and difficulty reusing data will limit value from data; (v) data deprivation, digital gaps and digital divides are not just a by-product of unequal global development, but will magnify the unequal impacts of a global crisis, and will be magnified in turn by global crises; (vi) having more data and even better data analytical techniques, such as artificial intelligence, does not guarantee that development outcomes will improve; (vii) decentralised data gathering and use can help to build trust – particularly important for coordination of behaviour.
Exploring Academic Self-Concepts Depending on Acculturation Profile. Investigation of a Possible Factor for Immigrant Students’ School Success

Academic achievement and academic self-concepts are reciprocally related; hence, investigating academic self-concepts should offer a potential approach for gaining a better understanding of immigrant students’ (lack of) school success. Proposing that immigrant students’ acculturation orientations need to be taken into account, in this study, we empirically investigate whether immigrant students’ general and domain-specific academic self-concept facets differ from those of non-immigrant students depending on their acculturation profile. Based on data from the German National Educational Panel Study (NEPS), we find initial indications that immigrant students’ academic self-concept facets are subject to their acculturation profile. The idea that acculturation may influence the known comparisons relevant for self-concept development will be discussed.
Study of the UTBB BESOI Tunnel-FET working as a Dual-Technology Transistor

In this work, we further investigate the operation of the BESOI (Back-Enhanced Silicon-On Insulator) Dual-Technology FET, analyzing not only its behavior as a p-type Tunnel-FET when a negative back bias is applied to the struc-ture, but also as an nMOS when a positive back bias is ap-plied. The working principle is based on the generation of a channel of either holes or electrons by the back gate electric field, which can then be depleted through the front gate bias. TCAD device simulation was used for the proof of concept.
E-democracy and the parrhesia language of netizen towards COVID-19 pandemic

The world has entered the era of digital democracy. Netizens (citizens of the internet) can deliver the facts or truths of an event through online media. On the other hand, the Coronavirus (COVID-19) pandemic has changed world order in different terms. The netizens can use parrhesia to deliver views to the world through internet. This paper studies the parrhesia democracy by netizens about COVID-19. The used questions were answered by the discourse semiotics approach. Data collection was done through distributing questionnaires online. The results revealed that the netizens’ freedom to use parrhesia concerning COVID-19 on the internet media raises ambiguous facts or information. Various myths or hoaxes that spread on social media have confused people in dealing with COVID-19. Social media with e-democracy provides free and uncontrolled opportunities in distributing opinions. However, the freedom to provide information without based on facts also results in myths or hoaxes which, later, have a universal meaning in society.
Formulation of conductive nanocomposites by incorporating silver‐doped carbon quantum dots for efficient charge extraction

Poly(3,4‐ethylenedioxy thiophene):poly(styrenesulfonate) (PEDOT:PSS) has been investigated as a hole transport material in organic‐inorganic hybrid perovskite solar cells (PSCs) with a p‐i‐n architecture. However, the intrinsic acidic nature of PEDOT:PSS induces interfacial protonation and degrades the quality of the thin film, resulting in low charge conductivity, low perovskite crystallinity, and poor device stability. In this work, we demonstrate the effect of adding carbon quantum dots doped with silver (Ag‐CQDs) to the PEDOT:PSS hole transport layer (HTL) to improve charge extraction, increase electrical conductivity, and hence, enhance the performance of hybrid PSCs. The proposed method enables facile one‐step hydrothermal synthesis of the Ag‐CQDs in the presence of a nitrogen‐containing carbon precursor. The incorporation of PEDOT:PSS containing Ag‐CQDs in PSCs noticeably increased the short circuit current density (Jsc) in the optimised devices, enhancing the device performance and ensuring long‐term durability of PSCs, compared with the pristine. The performance improvement is the result of highly efficient hole extraction because of the enhancement of electrical properties of PEDOT:PSS by Ag‐CQD. It is also attributed to the improved perovskite crystallinity, which depends on the increased surface energy of HTL. This work provides an efficient route to realise more stable PSCs capable of delivering outstanding charge dynamics.
Middle Ordovician trilobites from the Houping Formation of South China: implications for palaeoecology and palaeobiogeography

ABSTRACT Seventeen trilobite species belonging to 16 genera and 13 families are systematically documented from the Houping Formation (upper Dapingian-lower Darriwilian, Middle Ordovician) at the Datangkou and Dacao sections, Chengkou, northern Chongqing. Of these, a new species, Mioptychopyge chengkouensis sp. nov., is established and described. New morphological information is provided for previously known species on the basis of new specimens. Two trilobite associations based on faunal composition and dominant forms are distinguished from the Houping Formation, in ascending order, the Agerina Association (from the lower and middle members) and the Nileus-Illaenus Association (from the upper member). The Agerina Association lived in an inner shelf margin environment with carbonate substrate above storm wave base (<70 m deep), whereas the Nileus-Illaenus Association developed in a shallow outer shelf environment below storm wave base (>70 m deep), indicating a rise of relative sea level corresponding to the early Darriwilian transgression. The cluster and nonmetric multidimensional scaling analyses of the trilobites in the formation show that the fauna had a strong endemicity to South China and a close biogeographic connection with east Peri-Gondwana, especially Tarim, Annamia and central Iran.LSIDurn:lsid:zoobank.org:pub:E4E6AD0B-417F-4522-83E3-4DC44B647760
The Response of Chinese Fir Forest Tree Ring
Growth to Climate Change in China’s
Dagangshan Region

Chinese fir (Cunninghamia lanceolata (Lamb) Hook. ) in the Dagangshan region of Jiangxi Province in southern China was selected to explore the impact of climatic factors on tree ring width growth. Results showed that the signal-to-noise ratio (SNR) and mean sensitivity (MS) were large while the first order autocorrelation coefficient (FOAC) was small, and the chronology contains abundant climatic information. The tree ring width index of Chinese fir was significantly positively correlated with the precipitation in December of the previous year and June of the current year, and significantly negatively correlated with that in the current May and August. The tree ring width index was significantly positively correlated with the temperature in April and May of the current year, but significantly negatively correlated with that in July of the current year. The tree ring width index had a good change consistency with the warmth index (Wi) and humidity index (Hi). The response function of Chinese fir ring width analysis shows that the warmth index is the main factor affecting tree ring growth, followed by the humidity index, mean annual precipitation, and mean annual temperature. The comprehensive effect of temperature and precipitation factors have significant influence on the tree ring width growth of Chinese fir. Results can provide a scientific basis for studying the effect of climatic factors on tree growth in sub-tropical regions in China and many other parts of the
