Meaning in life, connectedness, academic self-efficacy, and personal self-efficacy: A winning combination

Limited research has been conducted so far to explore how meaning in life can promote key academic and psychological benefits in a school context. The research reported here aimed to address this issue by assessing how meaning in life is associated with dimensions of connectedness, academic self-efficacy (Study 1) and personal self-efficacy (Study 2). Participants were two samples of Hong Kong secondary school students. Study 1 revealed that meaning in life was associated with a higher level of connectedness to parents, school, peers, and teachers, and academic self-efficacy (study skills, time management, critical and creative thinking, and involvement in learning). Most connectedness dimensions were linked to lower academic self-efficacy, apart from connectedness to school. Study 2 showed that meaning in life was linked to higher levels of connectedness and personal self-efficacy dimensions (positive self-concept, problem-solving, self-management, and self-reflection). Apart from connectedness to school, other connectedness dimensions were associated with lower personal self-efficacy. Across studies, meaning in life had indirect effects on both self-efficacy through the mediating influence of connectedness. Theoretical and practical implications are discussed.
A Double-blind, Placebo-controlled, Randomized Comparison of Analgesic Efficacy of Oral Ketorolac Versus Intramuscular Tramadol After Third Molar Surgery

Background: Pain due to dental extraction, particularly after the third molar extraction causes discomfort to patients. Different types of analgesics used to manage pain in such cases include nonsteroidal anti-inflammatory drugs and opioids. Objectives: To evaluate the pre-emptive analgesic effectiveness of oral ketorolac and intramuscular (IM) tramadol following lower third molar surgeries. Materials and Methods: A total 60 subjects with impacted mandibular third molars were included in our study. They were randomized into two treatment groups, each with 30 patients. Group A: oral ketorolac 10 mg and IM placebo (1 mL saline solution); Group B: oral placebo (tablet similar to oral ketorolac) and IM tramadol 50 mg diluted in 1 mL saline solution. The treatment regimen were given half an hour before the start the surgery. The parameters evaluated were pain intensity, the time of first analgesic rescue medication and total analgesic consumption. Results: We found that the time of first rescue analgesic medication was longer in oral ketorolac group than IM tramadol group (P=0.01). Group A patients experienced less pain than Group B patients. Conclusion: We found that oral ketorolac group of patients had an enhanced analgesic effectiveness and a longer time of first rescue analgesic than those taking intramuscular tramadol.
Exploring Job Crafting: Identifying the Way Lecturers of CLCS Adjust to Their Job

This study aimed to examine the job crafting practice among the lecturers of College of Language and Culture Studies (CLCS), Bhutan. The study applied quantitative research approach and used Slemp and Vella-Brodrick’s [1] Job Crafting Questionnaire to collect data. The data were collected from 42 lecturers (Male=35 and Female=7) of the college, and analyzed using SPSS to calculate descriptive analysis, frequency, mean and standard deviation. The findings showed that the participants of this study were highly engaged in job crafting. Of three forms of job crafting, relational crafting, cognitive crafting and task crafting, the findings suggested that participants were most likely to be engaged in relational crafting. Further, the findings showed that the lecturers who lacked job resources engaged more in job crafting. Also, it was found that while the gender does not influence job crafting practice, the demographic factor such as participants’ qualification and number of years in the job seem to be affecting their job crafting practice. The study has drawn some strategic implication for employee engagement and wellbeing enhancement.
Institutions and Scientific Progress

Scientific progress has many facets and can be conceptualized in different ways, for example in terms of problem-solving, of truthlikeness or of growth of knowledge. The main claim of the paper is that the most important prerequisite of scientific progress is the institutionalization of competition and criticism. An institutional framework appropriately channeling competition and criticism is the crucial factor determining the direction and rate of scientific progress, independently on how one might wish to conceptualize scientific progress itself. The main intention is to narrow the divide between traditional philosophy of science and the sociological, economic and political view of science that emphasizes the private interests motivating scientists and the subsequent contingent nature of the enterprise. The aim is to show that although science is a social enterprise taking place in historical time and thus is of a contingent nature, it can and in fact does lead to genuine scientific progress—contrary to the claims of certain sociologists of science and other relativists who standardly stress its social nature, but deny its progressive character. I will first deal with the factual issue by way of introducing the main concepts and mechanisms of modern institutional theory and by applying them to the analysis of the cultural phenomenon that we call modern science. I will then turn to the normative issue: what is the appropriate content of the institutional framework, for scientific progress to emerge and be sustained at which level should it be set and by whom? Addressing this problematic is equivalent to conducting a constitutional debate leading to a Constitution of Science.
Sodium Carboxyl Methyl Cellulose for Improvement of the Determination of Polyethylene Glycol Modified Carbon Nanotubes by Raman Spectroscopy

Single-walled carbon nanotubes (SWNTs) have shown great potential in various areas of biomedicine. However, few research studies have focused on in vivo carbon nanotube detection by Raman spectroscopy. In this work, SWNTs were functionalized with polyethylene glycol (PEG) to form PEG-o-SWNTs to improve the biocompatibility and dispersibility. A novel application of Raman scattering was used to detect the PEG-o-SWNTs. Compared to the traditional assay method, the recovery rate was improved from 84.2% to 102.7%, the correlation coefficient of the standard curve increased from 0.7315 to 0.9872, and the degree of precision decreased from 4.4% to 3.1%. Large errors in the measured results were found the cryopreserved blood and organ samples in which the reticular sediments separated, on which the nanotubes generally concentrate. It was determined that by achieving a final concentration of 0.5% through the addition of sodium carboxyl methyl cellulose (CMC-Na), the homogeneity of the tested sample can be greatly enhanced, thus boosting the accuracy of the analyses. This work offers methods with higher accuracy for determining the presence of PEG-o-SWNTs in blood and organs using Raman spectroscopy.
ADID-UNET—a segmentation model for COVID-19 infection from lung CT scans

Currently, the new coronavirus disease (COVID-19) is one of the biggest health crises threatening the world. Automatic detection from computed tomography (CT) scans is a classic method to detect lung infection, but it faces problems such as high variations in intensity, indistinct edges near lung infected region and noise due to data acquisition process. Therefore, this article proposes a new COVID-19 pulmonary infection segmentation depth network referred as the Attention Gate-Dense Network- Improved Dilation Convolution-UNET (ADID-UNET). The dense network replaces convolution and maximum pooling function to enhance feature propagation and solves gradient disappearance problem. An improved dilation convolution is used to increase the receptive field of the encoder output to further obtain more edge features from the small infected regions. The integration of attention gate into the model suppresses the background and improves prediction accuracy. The experimental results show that the ADID-UNET model can accurately segment COVID-19 lung infected areas, with performance measures greater than 80% for metrics like Accuracy, Specificity and Dice Coefficient (DC). Further when compared to other state-of-the-art architectures, the proposed model showed excellent segmentation effects with a high DC and F1 score of 0.8031 and 0.82 respectively.
Decreasing Atmospheric CO2 During the Late Miocene Cooling

A pronounced late Miocene cooling (LMC) from ~7 to 5.7 Ma has been documented in extratropical and tropical sea surface temperature records, but to date, available proxy evidence has not revealed a significant pCO2 decline over this event. Here, we provide a new, high‐resolution pCO2 proxy record over the LMC based on alkenone carbon isotopic fractionation (εp) measured in sediments from the South Atlantic at Ocean Drilling Program (ODP) Site 1088. We apply a recent proxy calibration derived from a compilation of laboratory cultures, which more accurately reflects the proxy sensitivity to pCO2 changes during late Quaternary glacial‐interglacial cycles, together with new micropaleontological proxies to reconstruct past variations in algal growth rate, an important secondary influence on the εp. Our resulting pCO2 record suggests an approximately twofold to threefold decline over the LMC and confirms a strong coupling between climate and pCO2 through the late Miocene. Within this long‐term trend are pCO2 variations on sub‐myr timescales that may reflect 400‐kyr long‐eccentricity cycles, in which pCO2 minima coincide with several orbital‐scale maxima in published high‐resolution benthic δ18O records. These may correspond to ephemeral glaciations, potentially in the Northern Hemisphere. Our temperature and planktonic δ18O records from Site 1088 are consistent with substantial equatorward movement of Southern Ocean frontal systems during the LMC. This suggests that potential feedbacks between cooling, ocean circulation and deep ocean CO2 storage may warrant further investigation during the LMC.
A local meshless procedure to determine the unknown control parameter in the multi-dimensional inverse problems

This article is devoted to applying a local meshless method for specifying an unknown control parameter in one- and multi-dimensional inverse problems which are considered with a temperature overspecification condition at a specific point or an energy overspecification condition over the computational domain. Finding the unknowns in inverse problems is a challenge because these problems are modeled as non-classical parabolic problems and also have a significant role in describing physical phenomena of the real world. In this study, a combination of the meshless method of radial basis functions and finite difference method (called radial basis function-finite difference method) is used to solve inverse problems because this method has two important features. First it does not require any mesh generation. Consequently, it can be exerted to handle the high-dimensional inverse problems. Secondly, since this method is local, at each time step, a system with a sparse coefficient matrix is solved. Hence, the computational time and cost will be much low. Various numerical examples are examined, and also the accuracy and computational time required are presented. The numerical results indicate that the mentioned procedure is appropriate for the identification of the unknown parameter of inverse problems.
A 10-year follow-up of key gas exchange exercise parameters in a general population: results of the Study of Health in Pomerania

Background Cardiopulmonary exercise testing (CPET) is a frequently used method for the evaluation of the cardiorespiratory system. The prognostic relevance of the measured parameters is commonly known. Longitudinal data on cardiorespiratory fitness in a large sample of well-characterised healthy volunteers are rare in the literature. Methods CPET data of 615 healthy individuals who voluntarily took part in the Study of Health in Pomerania (SHIP) at three different measurement times were analysed. The median observation time was 10.5 years. The age range was 25–85 years. Results Over the observed timeframe and with increasing age, a decline in maximum power, peak oxygen uptake (V′O2peak) and oxygen uptake at anaerobic threshold (V′O2@AT) was detectable. This decline was aggravated with increasing age. For the minute ventilation (V′E)/carbon dioxide production (V′CO2) slope, an increase was measured in individuals aged ≥50 years only. Conclusion The present study affirms the decrease in aerobic capacity with increasing age in a selected, well-characterised, healthy study sample, which seems to be less pronounced in females. A 10-year follow-up of the Study of Health in Pomerania affirms the decrease in aerobic capacity with increasing age in a selected, well-characterised, healthy study sample, which seems to be less pronounced in females https://bit.ly/3pIJmpM
The aplication of Pistacia khinjuk extract nanoemulsion in a biopolymeric coating to improve the shelf life extension of sunflower oil

Abstract In the present study, a hydroalcoholic extract of P. khinjuk was obtained by sonication method at 60°C for 50 min. The measurement revealed that the total phenolic content of the extract was 46.0 mg/g. The results showed that the extract has an antioxidant activity of 73.5% and 8.3 (µmol TE/g DW) in DPPH radical scavenging method and FRAP assay, respectively. Also, Balango (Lallemantia royleana) and Fenugreek (Trigonella foenum‐graecum) seed gum and their composition (1:1) were used to prepare the nanoemulsion with P. khinjuk extract. The droplet mean size of nanoemulsions was ranged from 310.34 to 354.19 nm. The highest encapsulation efficiency was observed in Balango nanoemulsion. P. khinjuk extract nanoemulsion coating with Balango and TBHQ was added to sunflower oil at 200 and 100 ppm, respectively. During 24‐day storage at 60°C, samples were investigated for peroxide, acid, and p‐anisidine values at 4‐day intervals. The results showed that oils containing nanoemulsion had the highest stability during storage. However, in all samples peroxide, acid and p‐anisidine values increased but the rate of oxidation in samples containing both synthetic and natural antioxidants was slower than the control sample.
Maximum-variance gradiometer technique for removal of spacecraft-generated disturbances from magnetic field data

Abstract. In situ measurement of the magnetic field using spaceborne instruments requires a magnetically clean platform and/or a very long boom for accommodating magnetometer sensors at a large distance from the spacecraft body. This significantly drives up the costs and the time required to build a spacecraft. Here we present an alternative sensor configuration and a technique allowing for removal of the spacecraft-generated AC disturbances from the magnetic field measurements, thus lessening the need for a magnetic cleanliness programme and allowing for shorter boom length. The final expression of the corrected data takes the form of a linear combination of the measurements from all sensors, allowing for simple onboard software implementation. The proposed technique is applied to the Service Oriented Spacecraft Magnetometer (SOSMAG) on board the Korean geostationary satellite GeoKompsat-2A (GK2A). In contrast to other missions where multi-sensor measurements were used to clean the data on the ground, the SOSMAG instrument performs the cleaning on board and transmits the corrected data in real time, as needed by space weather applications. The successful elimination of the AC disturbances originating from several sources validates the proposed cleaning technique.
Determinants of Dividend Payout Ratio in Non-Financial Companies Listed

This study aims to analyze the effect of both internal and external factors that determine the dividend payout ratio of non-financial companies listed in the IDX High dividend 20 during the period of 2015-2019. The independent variables of the company's internal factors are return on assets, earnings per share, and debt to equity ratio. The independent variables of the company's external factors are interest rates and inflation. The control variable used in this study is firm size. There were 13 companies listed in IDX High Dividend 20 by using the purposive sampling method. Data analysis used panel data regression which was analyzed three times by grouping the dividend payout ratio, low dividend, and high dividend. The results showed that the return on assets had a significant negative effect on the combined dividend payout ratio with a probability value (0.0309) and high dividend with a probability value (0.0067) smaller than the significance level (5%), but had no significant effect on the low dividend with a probability value (0.3283) greater than the significance level (5%). Earnings per share has no significant effect on the combined dividend payout ratio with a probability value (0.4151), low dividend with a probability value (0.1164), and high dividend with a probability value (0.3835) greater than the significance level (5%). It can be concluded that return on assets earning per share, firm size, and debt to equity ratio have an effect on dividend payout ratio. Copyright © Universitas Pendidikan Ganesha.

Salmon lice-induced mortality of Atlantic salmon during post-smolt migration in Norway

The expansion of salmonid aquaculture has resulted in environmental challenges, including salmon lice that may infest both farmed and wild fish. For wild Atlantic salmon post-smolts that migrate from their rivers to the ocean, the first phase of their journey in the coastal zone, where aquaculture occurs, is critical when considering lice exposure. To evaluate the lice influence during the post-smot migration we have developed a migration model. An archive with spatiotemporal concentrations of lice larvae in Norwegian coastal waters has been established using a combination of state-of-the-art hydrodynamic and lice biology models. To estimate lice-induced mortality of wild salmon from Norwegian rivers, the infestation level on the virtual post-smolts was calibrated to match that observed on wild post-smolts genetically assigned their rivers of origin. The lice infestation pressure was modelled on post-smolts from 401 rivers covering all of Norway. Based on this, aquaculture-produced salmon lice-induced mortality of wild salmon post-smolts was estimated as <10% for 179 rivers, 10–30% for 140 rivers, and >30% for 82 rivers in 2019. Estimated mortalities were used together with other data sets to evaluate aquaculture sustainability in Norway. The aquaculture regulatory system represents a globally leading example of science-based management that considers the environmental impact.
Urine Output Calculated Using Actual Body Weight May Result in Overestimation of Acute Kidney Injury for Obese Patients

Supplemental Digital Content is available in the text ABSTRACT Goal: The derived hourly urine output (UO) indexed by body weight is one of the major criteria for the diagnosis of acute kidney injury (AKI). However, it is unclear whether actual body weight (ABW) or ideal body weight (IBW) should be used. This study aims to explore whether UO calculation based on ABW might lead to overestimation of AKI. Method: AKI patients identified in the Medical Information Mart for Intensive Care III database by different components of the Kidney Disease Improving Global Outcomes guidelines and different definitions of body weight were retrospectively studied. Hospital and 90-day mortality were compared to decide whether different patient groups had the same outcome. Results: In the cohort of 14,725 patients, AKI was identified in 4,298 (29.19%) and 3,060 (20.78%) patients respectively when ABW or IBW was used (P < 0.01). Multivariate logistic regression revealed that AKI patients identified by UO calculated from ABW had similar hospital and 90-day mortality to that of patients with no evidence of AKI. Whereas AKI patients identified by serum creatinine changes, or those identified by both ABW and IBW, had twice higher the risks of hospital death and about 1.5 times higher the risks of 90-day death compared with thoese with no evidence of AKI. Results were confirmed in two separate sensitivity analyses where patients whose admission creatinine levels were within the normal reference ranges and patients identified as sepsis were studied. Conclusions: Calculating hourly body weight normalized UO using ABW may lead to underestimation of UO and overestimation of AKI.
Rarefied particle motions on hillslopes: 1. Theory

We describe the probabilistic physics of rarefied particle motions and deposition on rough hillslope surfaces. The particle energy balance involves gravitational heating with conversion of potential to kinetic energy, frictional cooling associated with particle-surface collisions, and an apparent heating associated with preferential deposition of low energy particles. Deposition probabilistically occurs with frictional cooling in relation to the distribution of particle energy states whose spatial evolution is described by a Fokker-Planck equation. The Kirkby number Ki — defined as the ratio of gravitational heating 5 to frictional cooling — sets the basic deposition behavior and the form of the probability distribution fr(r) of particle travel distances r, a generalized Pareto distribution. The shape and scale parameters of the distribution are well-defined mechanically. For isothermal conditions where frictional cooling matches gravitational heating plus the apparent heating due to deposition, the distribution fr(r) is exponential. With non-isothermal conditions and small Ki this distribution is bounded and represents rapid thermal collapse. With increasing Ki the distribution fr(r) becomes heavy-tailed and represents net particle heating. 10 It may possess a finite mean and finite variance, or the mean and variance may be undefined with sufficiently large Ki . The formulation provides key elements of the entrainment forms of the particle flux and the Exner equation, and it clarifies the mechanisms of particle-size sorting on large talus and scree slopes. Namely, with conversion of translational to rotational kinetic energy, large spinning particles are less likely to be stopped by collisional friction than are small or angular particles for the same surface roughness. 15
Responsible Innovation in SMEs: A Systematic Literature Review for a Conceptual Model

Responsible innovation has always been an important issue in discourses addressing the major challenges faced by humankind in terms of natural resource degradation, climate change, economic progress and societal well-being. However, its integration into industry is still in its infancy, and even more so when it comes to small and medium-sized enterprises (SMEs). The aim of this research is to use a systematic literature review to develop a conceptual model for responsible innovation and its relationship with SME performance, in connection with sustainable innovation and corporate social responsibility practices. A bibliometric analysis of 102 articles collected between 2000 and April 2020 from the Web of Science database was used, in addition to the systematic literature review using the Gephi and NVivo software. The study presents an overview of the articles, authors, and most influential journals and research clusters identified, and provides a solid conceptual framework to be applied in this field and in the context of SMEs.
