Social support at work and workload as predictors of satisfaction with life of Peruvian teachers

The repercussions of the coronavirus disease (COVID-19) have generated effects on the working modality of teachers, in whom it is convenient to study variables associated with well-being. The objective with this research was to determine whether social support at work and workload predict satisfaction with life in a sample of Peruvian teachers. The methodology was a predictive and cross-sectional study, carried out on 584 Peruvian teachers of both genders selected in a non-probabilistic way; to whom the social support scale at work, the workload scale and the life satisfaction scale were applied. The survey was carried out virtually, and descriptive statistics, Pearson’s correlation coefficient and structural equation modelling (SEM) were conducted to examine the hypothetical model. In the analysis of the proposed model, an adequate fit was obtained, 2 (116) = 435.5, p < . 001, CFI = . 963, RMSEA = . 069, SRMR = . 059. Thus, H1 and H2 were confirmed on the positive effect of social support at work,  = . 27, p < . 001, and the negative effect of workload,  = . 28, p < . 001 in satisfaction with life. Likewise, the t values of the beta regression coefficients of the predictor variables were highly significant (p < 0.01). It was concluded that social support at work and an adequate workload predict a better level of satisfaction with life in a sample of Peruvian teachers.
Association between Serum Lactate and Morbidity and Mortality in Neonates: A Systematic Review and Meta-Analysis

Objective: Lactate is a marker of hypoperfusion in critically ill patients. Whether lactate is useful for identifying and stratifying neonates with a higher risk of adverse outcomes remains unknown. This study aimed to investigate the association between lactate and morbidity and mortality in neonates. Methods: A meta-analysis was performed to determine the association between blood lactate levels and outcomes in neonates. Ovid MEDLINE, EMBASE, Cochrane Library, and ClinicalTrials.gov were searched from inception to 1 May 2021. A total of 49 observational studies and 14 data accuracy test studies were included. The risk of bias was assessed using the Newcastle-Ottawa Scale for observational studies and the QUADAS-2 tool for data accuracy test studies. The primary outcome was mortality, while the secondary outcomes included acute kidney injury, necessity for renal replacement therapy, neurological outcomes, respiratory morbidities, hemodynamic instability, and retinopathy of prematurity. Results: Of the 3184 articles screened, 63 studies fulfilled all eligibility criteria, comprising 46,069 neonates. Higher lactate levels are associated with mortality (standard mean difference, −1.09 [95% CI, −1.46 to −0.73]). Using the estimated sensitivity (0.769) and specificity (0.791) and assuming a prevalence of 15% for adverse outcomes (median of prevalence among studies) in a hypothetical cohort of 10,000 neonates, assessing the lactate level alone would miss 346 (3.46%) cases (false negative) and wrongly diagnose 1776 (17.76%) cases (false positive). Conclusions: Higher lactate levels are associated with a greater risk of mortality and morbidities in neonates. However, our results do not support the use of lactate as a screening test to identify adverse outcomes in newborns. Research efforts should focus on analyzing serial lactate measurements, rather than a single measurement.
Polymer-Integrated Optical Fiber Photothermal Fabry–Perot Interferometer for High Sensitivity Detection of β-Carotene

<inline-formula> <tex-math notation="LaTeX">$\beta $ </tex-math></inline-formula>-carotene is an important precursor of vitamin A. Excessive consumption can cause carotenemia, which endangers human liver and kidney functions. Therefore, the detection of <inline-formula> <tex-math notation="LaTeX">$\beta $ </tex-math></inline-formula>-carotene is important for protecting human health. However, current detection methods are costly, time-consuming, and not suitable for online detection. In this study, an optical fiber Fabry–Perot interferometer (FPI) is proposed that contains a single-mode fiber (SMF), multimode fiber (MMF), and polydimethylsiloxane (PDMS). The PDMS not only acts as a cavity but also as a sensing unit. Because PDMS has a large coefficient of thermal expansion, it responds well to photothermal signals. The analyte <inline-formula> <tex-math notation="LaTeX">$\beta $ </tex-math></inline-formula>-carotene produces a photothermal effect (PTE) under laser irradiation at 480 nm, which can change the transport characteristics of the FPI. The experimental results show that the sensitivity reaches 50 pm/(mg/L) with a limit of detection (LOD) of 0.4 mg/L, which is lower than that of the conventional liquid chromatography method. This sensor has a simple structure, high sensitivity, high mechanical strength, and good stability; therefore, it has potential applications in food safety and environmental pollution detection.
The Effects of Dietary Silybin Supplementation on the Growth Performance and Regulation of Intestinal Oxidative Injury and Microflora Dysbiosis in Weaned Piglets

Oxidative stress is the major incentive for intestinal dysfunction in weaned piglets, which usually leads to growth retardation or even death. Silybin has caught extensive attention due to its antioxidant properties. Herein, we investigated the effect of dietary silybin supplementation on growth performance and determined its protective effect on paraquat (PQ)-induced intestinal oxidative damage and microflora dysbiosis in weaned piglets. In trial 1, a total of one hundred twenty healthy weaned piglets were randomly assigned into five treatments with six replicate pens per treatment and four piglets per pen, where they were fed basal diets supplemented with silybin at 0, 50, 100, 200, or 400 mg/kg for 42 days. In trial 2, a total of 24 piglets were randomly allocated to two dietary treatments with 12 replicates per treatment and 1 piglet per pen: a basal diet or adding 400 mg/kg silybin to a basal diet. One-half piglets in each treatment were given an intraperitoneal injection of paraquat (4 mg/kg of body weight) or sterile saline on day 18. All piglets were euthanized on day 21 for sample collection. The results showed that dietary supplementation with 400 mg/kg silybin resulted in a lower feed conversion ratio, diarrhea incidence, and greater antioxidant capacity in weaned piglets. Dietary silybin enhanced intestinal antioxidant capacity and mitochondrial function in oxidative stress piglets induced by PQ. Silybin inhibited mitochondria-associated endogenous apoptotic procedures and then improved the intestinal barrier function and morphology of PQ-challenged piglets. Moreover, silybin improved intestinal microbiota dysbiosis induced by the PQ challenge by enriching short-chain fatty-acid-producing bacteria, which augmented the production of acetate and propionate. Collectively, these findings indicated that dietary silybin supplementation linearly decreased feed conversion ratio and reduced diarrhea incidence in normal conditions, and effectively alleviated oxidative stress-induced mitochondrial dysfunction, intestinal damage, and microflora dysbiosis in weaned piglets.
This is not US: measuring polarization in multiparty systems. A quasi-replication study

In the last decade, affective polarization (AP) has become an increasingly salient topic in both public discourse and political science. Several different measurement instruments have been developed to empirically capture this phenomenon. With the rising interest that affective polarization is now also enjoying in Europe, it has become of the utmost importance to assess what these different measures capture, and to what extent their application travels to different contexts. In this study we test several AP measures on a student population with various European nationalities. We assess their overlap and effectiveness in mapping AP, to help future research working towards greater empirical clarity, and making informed choices on which kind of measures to include in questionnaires and data collections. The results indicate that, while different items usually produce different point estimates and sometimes different answer patterns, the measurement of affective polarization appears relatively indifferent to the choice of items.
Assessing the impact of fiscal shocks on output In MENAP countries

This note is a reference guide to the econometric work on fiscal multipliers for MENAP countries. Spending and tax multipliers are estimated from conventional VAR models and identified using a sign-restrictions approach. Estimates show that fiscal multipliers tend to be small, except for those associated with government investment spending, which generally exceed unity. For the average MENAP country, fiscal multipliers for current spending, government consumption and government investment spending are 0.5, 0.8, and 1.1,respectively, while the tax revenues multiplier is estimated at around –0.4. There is also significant variation in the size of these multipliers across countries, consistent with differences in economic fundamentals, such as openness to trade and the flexibility of the exchange rate. The estimated multipliers are generally consistent with theoretical priors, and are in line with the evidence from the literature for other economies and categories of spending and taxes.
The Relationship between Health Insurance and Pharmaceutical Innovation: An Empirical Study Based on Meta-Analysis

The growing research interest in the relationship between health insurance and pharmaceutical innovation is driven by their significant impact on healthcare optimization and pharmaceutical development. The existing literature, however, lacks consensus on this relationship and provides no evidence of the magnitude of a correlation. In this context, this study employs meta-analysis to explore the extent to which health insurance affects pharmaceutical innovation. It analyzes 202 observations from 14 independent research samples, using the regression coefficient of health insurance on pharmaceutical innovation as the effect size. The results reveal that there is a strong positive correlation between health insurance and pharmaceutical innovation (r = 0.367, 95% CI = [0.294, 0.436]). Public health insurance exhibits a stronger promoting effect on pharmaceutical innovation than commercial health insurance. The relationship between health insurance and pharmaceutical innovation is moderated by the country of sample origin, data range, journal type, journal impact factor, type of health insurance, and research perspective. Our research findings further elucidate the relationship mechanism between health insurance and pharmaceutical innovation, providing a valuable reference for future explorations in pharmaceutical fields.
Ergonomic Product Design: An Empirical Study on The Influencing Factors to Use and to Buy

Ergonomic design in various types of products has been introduced in many countries. This study is aimed at observing the intention to use and to buy ergonomic products. A conceptual model of intention to use and to buy ergonomic product design is developed based on the Technology Acceptance Model. Dimensions and construction of the model are developed based on the literature and an experiment. Eight hundred and three respondents were involved by filling out the questionnaire, consisting of 7 dimensions and 23 statements. The result shows that perceived design, perceived comfort, perceived social image, perceived ease of use, and perceived usefulness influence the intention to use ergonomic product design. The intention to use will influence the intention to buy, which finally influences the continuance to use. Implications of the result are discussed.
Oro-Anal Transit Time and Colon Manometry: Predictability and Outcomes in Children With Functional Constipation

Objectives: The primary objective of the study was to evaluate the correlation of oro-anal transit time (OTT) using SITZMARKS® (Konsyl Pharmaceuticals Inc., Easton, MD, USA) with colonic manometry (CM) in children with chronic idiopathic constipation (CIC). The secondary objective was to determine the clinical utility of these studies in directing treatment strategies. Methods: A retrospective chart review of 44 children with CIC was evaluated with both OTT and CM. The median follow-up was one year (0.3 to 7). Results: Seventeen children had normal OTT, and 27 had abnormal OTT (slow-transit constipation (STC)). There was no statistical difference between the percentage of children with abnormal CM (13) test results categorized by OTT (23.5% normal OTT vs. 33% abnormal OTT, p = 0.73). A change in therapy was accepted by all 13 children with abnormal CM, but only 26/31 (84%) of the children had normal CM. The CM test results prompted acceptance of treatment change (appendicectomy or medication escalation) in 89% of children. Overall, 31/44 (70%) of children undergoing CM testing had improvement in clinical symptoms. More children with abnormal CM testing improved vs. normal CM but did not reach significance (85% vs. 65%, p = 0.28). Conclusion: Contrary to previous studies, OTT results did not predict the presence of colonic dysmotility based on colon motility testing. Colonic manometry testing resulted in the acceptance of a change in therapy in approximately 90% of children. More children with colonic dysmotility improved versus those with normal CM studies. Other interventions beyond stimulant laxatives should be considered in children with refractory constipation.
Application of Gradient-Dependent Optimal Interpolation in Fishery Analysis of Neon Flying Squid (Ommastrephes bartramii) in the Kuroshio–Oyashio Confluence Region

Simple Summary This paper provides a novel approach to integrating available environmental information into fishery data using gradient-dependent optimal interpolation. Comparative verifications of observations show that the constructed subsurface temperature and salinity profiles were very consistent with the in situ observations. The data assimilation method, named gradient-dependent optimal interpolation, gave refined matching results applied to represent the relationship between squid and environmental information. Our new method represents a useful tool in the deep research of fishery oceanography. Abstract A key issue in fishery forecasting is the collection of high-precision subsurface environmental data. A data assimilation method, named gradient-dependent optimal interpolation, was used to construct the near-real-time vertical temperature and salinity structure of a squid fishery ground based on Argo observations. The results were verified by truth-finding comparisons and applied to analyze the relationship between neon flying squid and the subsurface environment in the Kuroshio–Oyashio Confluence Region. The temperature and salinity differences between the constructed results and survey data were less than ±0.5 °C and ±0.02, respectively. Most of the relative analysis errors were less than the observational errors. Statistical analysis revealed that the most suitable temperature for squid was 18–24 °C at the near-surface (<5 m), although the squid can endure a temperature range from 11 to 12 °C at a depth of 300 m. There was an obvious thermocline in the fishery ground, with a thermocline depth of 65 m and a mean strength of approximately 0.10 °C/m. The regressive relationship between vertical temperature (thermocline parameters) and squid catch per unit effort (CPUE) followed the exponential (Gaussian) function. The most suitable salinity was 33.0–34.2 at depths shallower than 300 m.
Cork oak (Quercus suber) in the dynamism of a forest landscape shaped by fire on Monte Pisano (Tuscany N-W, Italy)

The plant landscape of Monte Pisano is characterized by a predominant forest component, with Pinus pinaster and Castanea sativa, of clear anthropic imprint. Another important component is constituted by dynamically advanced scrubs and woods of evergreen sclerophylls of natural origin, although often differently altered by the anthropic action and/or by fires, and dominated by Quercus ilex. Quercus suber is often found within holm oak woods, and – with lower frequency – inside the pine forests. Cork oak, in some cases, becomes dominant going to constitute the northernmost cork forests in Tuscany. The frequency of fires in Monte Pisano in the last decades seems to have led to an increase in Q. suber surface due to its known resilience to wildfires. The aim of this research is: a) to define the distribution of Q. suber in the area also in relation to repeated fire events in the past; b) to provide an updated characterization of these stands using a phytosociological approach; c) to identify stands and groups of trees that can be used as "seed forests" for post-fire forest restoration purpose, in relation to their marginal population characteristic. The study suggests a relationship between the spread of cork oak and the historical pattern of fires. This wide spread should be protected by forms of forest management unfortunately absent in this territory.
Climatological variations of total alkalinity and total inorganic carbon Climatological variations of total alkalinity and total inorganic carbon in the Mediterranean Sea surface waters

A compilation of several cruises data from 1998 to 2013 was used to derive polynomial fits that estimate total alkalinity (AT) and total inorganic carbon (CT) from measurements of salinity and temperature in the Mediterranean Sea surface waters. The optimal equations were chosen based on the 10-fold cross validation results and revealed that a second and third order polynomials fit the AT and CT data respectively. The AT surface fit showed an improved root mean square error (RMSE) of ±10.6 μmol kg−1. Furthermore we present the first annual mean CT parameterization for the Mediterranean Sea surface waters with a RMSE of ±14.3 μmol kg−1. Excluding the marginal seas of the Adriatic and the Aegean, these equations can be used to estimate AT and CT in case of the lack of measurements. The seven years averages (2005–2012) mapped using the quarter degree climatologies of the World Ocean Atlas 2013 showed that in surface waters AT and CT have similar patterns with an increasing eastward gradient. The surface variability is influenced by the inflow of cold Atlantic waters through the Strait of Gibraltar and by the oligotrophic and thermohaline gradient that characterize the Mediterranean Sea. The summer-winter seasonality was also mapped and showed different patterns for AT and CT. During the winter, the AT and CT concentrations were higher in the western than in the eastern basin, primarily due to the deepening of the mixed layer and upwelling of dense waters. The opposite was observed in the summer where the eastern basin was marked by higher AT and CT concentrations than in winter. The strong evaporation that takes place in this season along with the ultra-oligotrophy of the eastern basin determines the increase of both AT and CT concentrations.
QPause: Quantum-Resistant Password-Protected Data Outsourcing for Cloud Storage

—Cloud storage provides an efficient and convenient way to manage data, but it also poses significant challenges to data security. The central issue with cloud storage is to ensure the ability of the data owner to control and manage the outsourced data. The password-protected secret sharing (PPSS) integrates password authentication and secret sharing to offer a fresh approach to secure private data. Users can share the risk of device corruption with a well-designed PPSS scheme and manage outsourced data with only human-memorizable passwords. To the best of our knowledge, none of the existing PPSS schemes can resist security threats in the post-quantum era, and there is an urgent need to design quantum-resistant solutions. However, post-quantum cryptography varies significantly from traditional cryptography, and it is challenging to design a quantum-resistant password-protected secret-sharing scheme for cloud storage. In this work, we take the first substantial step towards this challenge by proposing QPause, a quantum-resistant password-protected data outsourcing scheme for cloud storage. We first de-sign a basic quantum-resistant PPSS scheme based on the lattice secure against semi-honest adversaries with a secure channel. On this foundation, we propose a quantum-resistant round-optimal password-protected data outsourcing scheme against strong ad-versaries. In addition, we formally prove that our scheme is secure and robust under various attacks against adversaries with quantum computing capabilities. The comparison results show that our new scheme outperforms its foremost counterparts.
Local energy saliency for bottom-up visual attention

Visual attention is a key visual process of selection of information, with a wide variety of applications in vision systems and image processing. In this paper we hold and test a novel model based on the Koch & Ullman architecture of saliency-based attention. We propose a novel feature from maximum local energy, already used in edge and feature extraction, but in ways which aren't suitable in attention applications. The envelope of a bank of log Gabor filters (resembling the receptive fields of complex cells from visual cortex) is taken as a local energy measure. In our approach to the feature integration problem, across the scales of each orientation, we compute initial conspicuity maps employing the T2 Hotelling statistic, as a multivariate measure of variance, and taking by this way conspicuous points with maximum local energy. Normalizing and integrating these maps, gathering the highest values of variance, we obtain a unique final saliency measure. With this model we achieve improved results accounting for orientation pop-out and equivalent performance in a visual search task within cluttered natural scenes, both in comparison with analogue experiments previously published with a state of art model.
Hafting adhesives from the final Later Stone Age layers at Sehonghong, Lesotho: a case study and commentary on the use of imported resources by nineteenth-century San

ABSTRACT There is longstanding evidence in the archaeological record of southern Africa for the application of hafting adhesives in the production of composite tool technology. Despite the limitations in the preservation of organics in archaeological contexts, the preservation of these materials can inform us about aspects of technological production and function, including hafting arrangements, adhesive production and resource acquisition. In some instances where we see the prevalence of organic materials that are at odds with the ecological landscape, these same materials can also elucidate social interactions between cultural groups. This paper presents the results of the analysis by microscopy and gas chromatography-mass spectrometry (GC-MS) of hafting residues from stone tools from the ceramic final Later Stone Age assemblages at Sehonghong, Lesotho. It argues that an adoption of novel resources including Pinus sp. resin, castor oil and paraffin by nineteenth-century San facilitated the continued existence of hunter-gatherer lifeways in increasingly marginalised circumstances amid tense relationships between the last hunter-gatherers of the Maloti-Drakensberg, newly arriving Basotho communities and European colonists.
