In this study, a research model was developed that aimed to explore the influence of theology students' positive religious coping (PRC), problematic social media use (PSMU), and depression levels on their flourishing. A combined covariance-based structural equation modeling (CB-SEM) and artificial neural network (ANN) model were used to assess the developed model. Data were collected from 501 respondents using validated survey instruments, including the Religious Coping Scale, Bergen Social Media Addiction Scale, DAS-21 Depression subscale, and the Flourishing Scale. The respondents, 28.5% male participants and 71.5% female participants, within the age bracket of 18 to 34 years (mean = 22.79 years, SD = 4.12). The CB-SEM results indicated that depression levels and PSMU were significantly related to PRC. The results further indicated that PRC was positively related to and explained 40% of the variance in the flourishing factor. The ANN model predicted flourishing with an accuracy of 72% and 81.8% for training and testing, respectively. Confirming the CB-SEM results, the ANN demonstrated that PRC was the most important variable in predicting flourishing. These findings have practical implications for institutions of religious training to address depression levels and PSMU and encourage PRC among theology students. Future research should investigate longitudinal relationships and the impact of specific religious coping strategies on flourishing. [ABSTRACT FROM AUTHOR]

Reforming the research evaluation system is essentially a struggle between the academic aristocracy, which professes expert approaches to evaluation, and the scientific bureaucracy, which seeks to ensure the dictate of numerical indicators. A representative example is the evolution of this confrontation in China, where a long-term commitment to international scientometric databases made it possible to achieve world leadership in terms of the number of publications. However, these achievements were accompanied by negative effects caused by deterioration in the personnel policy of universities, the reduction of academic freedoms, changes in the publication behavior of researchers, and violations of scientific ethics. This led to a reform of the national evaluation system, namely, the strengthening of the role of expertise, the priority dissemination of scientific information at the national level, and the restriction of open access publications. This review considers the history of the formation of and changes in the research evaluation system in China, its positive and negative effects, as well as new scientific practices, their likely consequences, and the possibility to apply them in other countries.

Aim: To evaluate the effect of combining positron range correction (PRC) with point-spread-function (PSF) correction and to compare different methods of implementation into iterative image reconstruction for 124I-PET imaging. Materials and methods: Uniform PR blurring kernels of 124I were generated using the GATE (GEANT4) framework in various material environments (lung, water, and bone) and matched to a 3D matrix. The kernels size was set to 11 × 11 × 11 based on the maximum PR in water and the voxel size of the PET system. PET image reconstruction was performed using the standard OSEM algorithm, OSEM with PRC implemented before the forward projection (OSEM+PRC simplified) and OSEM with PRC implemented in both forward- and back-projection steps (full implementation) (OSEM+PRC). Reconstructions were repeated with resolution recovery, point-spread function (PSF) included. The methods and kernel variation were validated using different phantoms filled with 124I acquired on a Siemens mCT PET/CT system. The data was evaluated for contrast recovery and image noise. Results: Contrast recovery improved by 2–10% and 4–37% with OSEM+PRC simplified and OSEM+PRC, respectively, depending on the sphere size of the NEMA IQ phantom. Including PSF in the reconstructions further improved contrast by 4–19% and 3–16% with the PSF+PRC simplified and PSF+PRC, respectively. The benefit of PRC was more pronounced within low-density material. OSEM-PRC and OSEM-PSF as well as OSEM-PSF+PRC in its full- and simplified implementation showed comparable noise and convergence. OSEM-PRC simplified showed comparably faster convergence but at the cost of increased image noise. Conclusions: The combination of the PSF and PRC leads to increased contrast recovery with reduced image noise compared to stand-alone PSF or PRC reconstruction. For OSEM-PRC reconstructions, a full implementation in the reconstruction is necessary to handle image noise. For the combination of PRC with PSF, a simplified PRC implementation can be used to reduce reconstruction times. [ABSTRACT FROM AUTHOR]

In the 14th five-year plan of the PRC (2021–2025), consumer demand is considered as the basis for future economic development and GDP per capita growth. Stimulating consumption within the PRC is one of the tasks of the government for 2021. This article analyzes the factors affecting the expansion of consumer demand, and also analyzes the economic indicators associated with the selected issue. The article also draws conclusions about the impact of the United States-China trade war and the COVID-19 pandemic on changing consumption patterns in the PRC. [ABSTRACT FROM AUTHOR]

This article is dedicated to a comprehensive analysis of the data of the Seventh Census in China, conducted in 2020 and to the identification of the most important demographic and socioeconomic trends in the development of the population of the People's Republic of China. The relevance of this study is due to the impact that demographic changes have on the world's largest economy. Given the current high level of globalization and the scale of the PRC population, any risks and threats of a demographic nature have a direct impact not only on China's security but potentially on the situation in the Asia–Pacific region and the world as a whole. The practical significance of this work for Russia is obvious, in particular, from the point of view of improving the migration policy of the Russian Federation. This study is based on a large array of statistical data, including from the PRC National Bureau of Statistics. The quantitative and qualitative changes in the Chinese population are analyzed, including the ratio of birthrates, mortality, natural increase and fertility, gender and age imbalances, and internal migration.

Due to corruption and limited oversight, philanthropy in China has come under increasing scrutiny by both the Chinese government and public. In particular, corruption has impacted charities, resulting in operational funding declines that have also impacted legitimate charities serving the vulnerable. Hence, an increase in the number of Chinese charities without adequate transparency and needed good governance threatens the health of these organizations and their service groups. In response, the Chinese government enacted the 2016 Charity Law, implemented on September 1, 2016. Yet the impact of this law, if any, is unknown. We therefore conducted a literature review of the academic and gray literature to assess characteristics of the law, its strengths and limitations, and to explore anti-corruption case studies. In addition, we reviewed publicly available secondary data on the transparency status—complete financial information and responsible staff—of Chinese charity organizations and a group of health-related specific charities before and after the Law's enactment. This included the transparency scores of the top 100 charities and top 30 health-related charities in China. The academic literature we reviewed focused on general governmental corruption and little on charity-related corruption. However, the gray literature reflected a poor view of charities in China due to publicized claims of fund and abuse. Based on our secondary data analysis, we found charity organizations' transparency shows some variation but as a total continues to score low overall across the top net asset holding charities. Importantly, based on a regression analysis, the transparency scores of Chinese charities did not experience a significant change despite the Charity Law's enactment. In response, strengthening the Charity Law by enhancing enforcement of financial regulations and implementing systemic good governance measures is needed. Further, efficiency initiatives such as philanthropy de-administration, e-government, and outsourcing monitoring of Chinese charities to external agencies would promote trustworthiness and credibility of Chinese charity organizations now and in the future.

This study proposes a comprehensive approach to investigate water resource contamination by pesticides under the specific climatic and hydrological conditions of the Sudano-Sahelian climate. Samples were collected from traditional wells, boreholes, and a lake in Burkina Faso. A multiresidue analysis was developed for 25 pesticides identified during field surveys. Polar organic chemical integrative samplers (POCIS) were used to confirm trends observed with grab samples. Uptake kinetics of POCIS were assessed by in situ calibration. The proposed use of nonlinear least squares regression proved to be a robust approach for estimating time-weighted average concentration in cases of nonlinear uptake. High sampling rates for triazines in a quasi-stagnant lake were attributed to warm water temperatures (30.8 ± 1.3 °C). The combination of sampling techniques during a 3-year monitoring period allowed for identifying potential interactions between resources, seasonal patterns, and origins of contaminants. Atrazine, azadirachtin, carbofuran, chlorpyrifos, cypermethrin, dieldrin, imidacloprid, and profenofos exceeded 0.1 μg L−1, indicating a potential risk for the consumers. Ecological risk assessment was performed using the Pesticide Tool Index for fish, cladocerans, and benthic invertebrates. Peak concentrations of cypermethrin and chlorpyrifos were systematically associated with hazard to the studied taxa. [ABSTRACT FROM AUTHOR]

This paper uses the Dual Cut-offs Approach to measure multidimensional poverty in China at the national, rural-urban, regional and provincial levels using the China Family Panel Studies data from 2010. Five dimensions and thirteen indicators are considered for the enumeration of poverty. It is observed that irrespective of cut-offs and weights, rural poverty in China is three to nine times of urban poverty. Social insurance, toilet and cooking fuel are the major indicators contributing to both rural and urban poverty. More urban households in the Western region are deprived, but urban poor households are deprived in more indicators in the Central region, and some Eastern provinces are poorer than some of the Central provinces. Furthermore, the paper identifies the provinces that contribute most to national poverty levels and finds the sources of poverty in those provinces. [ABSTRACT FROM AUTHOR]

Due to errors, accuracy of Global Positioning System is not so high. Therefore, the Real Time Differential Global Poisoning System (RTDGPS) which is based on the successive transmission message of RTCM protocol, is using in real-time applications. Stability and accuracy of the system, significantly depends to a fast transmission of correction messages. These messages come from the reference station to the user stations and affected by the errors related to each satellite. Receiving correction factors which are transmitted by the reference station are facing with time-lag problem, which can increase the error of the RTDGPS. To overcome this problem, prediction algorithms are used. In this research, support vector machine (SVM) model is used to predict the pseudo range correction. Unfortunately, the practical use of SVM is limited because the quality of SVM models depends on a proper setting of SVM and SVM kernel parameters. Therefore, to determine the main parameters of the SVM, both particle swarm optimization (PSO) and genetic algorithm (GA), as two optimization techniques, are used. The proposed methodology has been implemented by a 6-s predicts time step. Simulations showed that the accuracy of GA-SVM and PSO-SVM are equal to 0.186 and 0.154, respectively.

In this work, a method combining polar organic chemical integrative samplers (POCIS) and ultraperformance liquid chromatography coupled with tandem mass spectrometry (UPLC-MS/MS) was assessed for the determination of two corrosion inhibitors (benzotriazole and methylbenzotriazole), seven pesticides (atrazine, diuron, isoproturon, linuron, metolachlor, penconazole, terbuthylazine), and four pharmaceuticals (carbamazepine, diclofenac, metformin, sulfamethoxazole) in river water. As a first step, two POCIS sorbents, hydrophilic-lipophilic balance (HLB) and Strata X-CW, were compared. The comparison of the uptake profiles of the studied compounds showed that the HLB sorbent provides better uptake (higher sampled amount and better linearity) than Strata X-CW except for the basic compound metformin. Since the sampling rate ( R) of POCIS depends on environmental factors, seven compounds were evaluated as potential performance reference compounds (PRCs) through kinetic experiments. Deisopropylatrazine-d5 (DIA-d5) and, as far as we know, for the first time 4-methylbenzotriazole-d3 showed suitable desorption. The efficiency of both compounds to correct for the effect of water velocity was shown using a channel system in which POCIS were exposed to 2 and 50 cm s. Finally, POCIS were deployed upstream and downstream of agricultural wine-growing and tree-growing areas in the Lienne River and the Uvrier Canal (Switzerland). The impact of the studied areas on both streams could be demonstrated. [Figure not available: see fulltext.] [ABSTRACT FROM AUTHOR]

The use of plant protection products (PPPs) in agro-environments can lead to undesired exposure of non-target organisms in non-target compartments. A year-round field survey was conducted in a vineyard in Northern Italy, for monitoring the changes in the structure of soil microarthropod communities under the application of PPPs, focusing on springtails and mites, both inside and 4 and 10 m outside the vineyard. Exposure to PPPs was estimated as time-weighted average soil concentrations. The fluctuations in the abundances of the different organisms after the application of PPPs, especially insecticides, were recorded. A recovery in abundances was observed at the end of the productive season outside the field and at the beginning of the next spring within the vineyard. Using multivariate statistical tools, the behaviour of each taxon in relation to the stressors was assessed. Some organisms were affected by the stressors, while others were favoured because of low vulnerability to PPPs and the indirect effect of the absence of other taxa. The principal response curves (PRC) method was the most sensitive tool for assessing PPP effects on soil arthropod communities. Strong differences were evident in the structure of the communities inside and outside the vineyard, with the communities sampled 4 and 10 m outside the vineyard being fairly similar, the latter considered as control. The role of physical stressors on community composition is recognised. However, chemical stressors, and in particular PPP exposure seemed to have larger effects on structural and functional characteristics of soil arthropod communities than physical stressors.

The purpose of the Water Framework Directive is to ensure the quality of the natural water across Europe. In this context, passive samplers have shown interesting capacities for the monitoring of contaminants in aqueous ecosystems. They allow the measurement of time-weighted average concentrations, overcoming many drawbacks of the spot-sampling techniques known to be expensive and time consuming. However, application of passive samplers such as polar organic chemical integrative samplers (POCIS) for the monitoring of hydrophilic contaminants requires calibration to define compound sampling rates; key parameters to deduce the pollutant water concentrations from the amounts of pollutants accumulated by the device. Unfortunately, sampling rates are influenced by a range of environmental factors; in that respect, a question remains: is it not evident to know to what extent the sampling rates obtained in laboratory experiments can be used in field conditions? The problem can be solved for hydrophobic samplers by using performance reference compounds (PRCs), and an ongoing challenge for POCIS is focused on the improvement of the quantitative aspect of this family of samplers. In this study, potential PRCs have been selected during a specific experiment and their performance was tested in the laboratory under two hydrodynamic conditions. Results revealed a good proportionality between elimination rates of PRCs and sampling rates of chemicals. Afterwards, the application of the approach under environmental conditions was assessed by deploying POCIS in the Arcachon Bay (France) where POCIS-PRC-derived water concentrations appear to be close to the simultaneous grab-sampling results.

Pesticide loads in streams are potentially one of the most relevant stressors for macroinvertebrate communities. Nevertheless, real effects provoked at the community level are still largely unknown. Model ecosystems are frequently used as tools for the risk assessment of pesticides, especially for their regulation, however, they can be also applied to site-specific risk assessment in order to gain better understanding of the responses of aquatic ecosystems to chemical stress. In the present work, an experimental system was composed of 5 artificial streams that reproduced a mountain lotic environment under controlled conditions. This study was aimed to better understand, whether (and how) the biological community was influenced by pesticides pulse exposures. 5 mixture load events were simulated over the productive season (March-July 2010): biological community was regularly sampled and nominal concentrations of water were tested. The results were interpreted comparing the output of different metrics and statistical methodologies. The sensitivity of different metrics was analyzed considering single exposure events (maximum Toxic Units) as well as overall temporal trends. Results showed how some common taxonomic metrics (e.g. taxa richness, Shannon's index, total abundance of organisms, and the Extended Biotic Index) were not suitable to identify the effects of pesticides at community level. On the contrary EPT%, SPEAR and the Principal Response Curve methodology proved to be sensitive to this kind of stress, providing comparable results. Temporal trends of these metrics proved to be related to the concentration of chemicals. Remarkably, the first Principal Response Curve illustrates the trend followed by the most vulnerable species, while the second is more related to the trend of opportunistic species. A high potential risk for the invertebrate community was highlighted by a statistically significant decline of 40 points (comparison with the control) in both SPEAR and EPT%. [ABSTRACT FROM AUTHOR]

A tonic-clonic seizure transitions from high frequency asynchronous activity to low frequency coherent oscillations, yet the mechanism of transition remains unknown. We propose a shift in network synchrony due to changes in cellular response. Here we use phase-response curves (PRC) from Morris-Lecar (M-L) model neurons with synaptic depression and gradually decrease input current to cells within a network simulation. This method effectively decreases firing rates resulting in a shift to greater network synchrony illustrating a possible mechanism of the transition phenomenon. PRCs are measured from the M-L conductance based model cell with a range of input currents within the limit cycle. A large network of 3000 excitatory neurons is simulated with a network topology generated from second-order statistics which allows a range of population synchrony. The population synchrony of the oscillating cells is measured with the Kuramoto order parameter, which reveals a transition from tonic to clonic phase exhibited by our model network. The cellular response shift mechanism for the tonic-clonic seizure transition reproduces the population behavior closely when compared to EEG data. [ABSTRACT FROM AUTHOR]

This paper intends to provide an overview of the reorientation of education in China in the period 1998–2009 with regard to development issues. During this time, the focus has shifted gradually from the environment and health to education for sustainable development. The article centres on highlighting the main interventions and strategies adopted by China’s schools to make this reorientation possible, including: the introduction of new visions of sustainable development and project planning; the establishment of organisational mechanisms and capacity-building measures for their implementation in the field; the integration of ESD into teaching and learning processes; the maintenance of an action-research mechanism for innovations; and the sharing of lessons with both the national and the international community in order to make the implementation of ESD more effective.

In February 2007, the “Fetal Medicine Foundation Germany (FMF-D)” introduced its new calculation software for First Trimester Screening (FTS), called “Prenatal risk calculation (PRC)”. The aim of this study was to retrospectively investigate the test performance of PRC in comparison to the “NT module of the JOY software (JOY)”. A total of 3,516 combined first trimester screenings from 11 + 0 to 13 + 6 weeks of gestation were accomplished according to the FMF-standard. Adjusted risk calculation for aneuploidy was performed with PRC and JOY. A total of 2,202 complete data sets of singleton pregnancies were analyzed, including 10 trisomy 21 cases, 4 trisomy 18 cases, and 1 trisomy 13 case. Risk calculation with PRC and JOY showed highly significant results ( P value < 0.0001). JOY attained, at a cut-off of 1:300 (sensitivity 82.4%, false-positive rate 3.6%, positive predictive value 15.2%) and at a cut-off of 1:230 (82.4, 2.4, 21.2%), a better test performance in comparison to PRC (76.5, 7.1, 7.7% and 76.5, 5.3, 10.2%, respectively). The differences were highly significant ( P value < 0.0001). In this preliminary study, PRC demonstrated highly significant results in detecting aneuploidies in FTS. However, in comparison to JOY, its test performance was significantly inferior. A twice higher false positive rate would have doubled unnecessary invasive testing in a prospective setting. We therefore recommend a methodical revision of PRC. [ABSTRACT FROM AUTHOR]
