The Temporal and Spatial Evolution of Ecosystem Service Synergy/Trade-Offs Based on Ecological Units

“Two ecological barriers and three shelters” (TEBTS), which has the effect of relieving ecological pressure, is the national ecological security pattern in China. Calculating the value of TEBTS ecosystem services, clarifying the synergy/trade-off relationships between ecosystem services, and maximizing the value of regional ecosystem services are of great significance for maintaining the security of the ecological civilization. At present, the research on ecosystem service synergy/trade-off has become the frontier field of ecology and related disciplines at home and abroad, and many research results have been obtained. However, there is still room and significance for continuing research to think about the synergy/trade-off relationship of ecosystems from the perspective of temporal and spatial heterogeneity: clarifying the spatial scope and spatial transmission characteristics of ecosystem service synergy/trade-off; exploring the trend of ecosystem service synergy/trade-off, and simulating the dynamic characteristics of natural factors affecting ecosystem services; and analyzing the characteristics of different spatial attributes that lead to the synergy/trade-off of ecosystem services. In this study, the Songhua River Basin (SRB), where the NFB is located, is used as the research area, the ecosystem services are simulated through the ecosystem assessment model, ecological unit (EU) is constructed as a research carrier, which is used to define the spatial scope of ecosystem services, and the influence of spatial characteristics and attribute characteristics on the change trend of the ecosystem service synergy/trade-off relationship is analyzed. The research found that water retention, soil conservation, and biodiversity did not change much from 2000 to 2015, and these ecosystem services have a greater value in the NFZ. The amount of carbon sequestration increased rapidly from 2010 to 2015. Crop production showed an increasing trend year by year. As the main grain production area, the Songnen Plain provides the main crop production function, which is greatly affected by humans. In the spatial characteristic, water retention, soil sequestration, and biodiversity present a very significant synergistic relationship, which is manifested in the obvious high-value aggregation characteristics in the NFZ, and crop production and the other four types of ecosystem services are in a trade-off relationship. At the time scale, the four types of ecosystem services, including water retention, soil conservation, biodiversity, and carbon sequestration, are synergistic, and crop production and water retention are synergistic. The vegetation types exhibiting a synergy/trade-off relationship are mainly broad-leaved forests, and the soil types are mainly luvisols and phaeozems. These EUs are mainly distributed in the NFZ and have spatial topological characteristics: the area and circumference of these EUs are smaller, the radius of gyration is also significantly smaller than that of other EUs, and the shape is more regular. By focusing on the spatial aggregation characteristics and changing trends of the ecosystem service synergy/trade-off and clarifying the influencing factors of the ecosystem service synergy/trade-off, the ecosystem services can be integrated, and the ecosystem can be optimized. Thus, the value of regional ecosystem services can be maximized, and a certain data foundation and theoretical support can be provided for major projects, such as ecological restoration and ecological environment governance, which is of great significance for improving the pattern of ecological security.

Plate load tests to analyze the load-settlement response of shallow foundations on sand beds reinforced with micropiles.

Micropiles can act as structural support for a new foundation and sustainable solution for existing foundations with advantages such as high load-carrying capacity and use in in situ conditions. Installing micropiles around the footing at some distance from the footing edge could turn out to be extremely helpful for existing distressed foundations where improvement is needed. An experimental investigation is carried out on a laboratory model square footing in the ongoing study, placed on sand, with micropiles driven around the footing. A parametric study focusing on the effect of the slenderness ratio of the micropiles, the state of sand beds, the micropile spacing ratio (S/b), and the micropile edge distance ratio (ED/d) are analyzed. The results demonstrate that the micropiles can appreciably improve the footing's settlement characteristics and load-bearing capacity when placed around it. The load-carrying capacity shows some appreciable increase by increasing the slenderness ratio of micropiles, but increasing the slenderness ratio beyond 20 is insignificant. For unreinforced footing, a denser form of sand was found more advantageous in terms of bearing capacity, while as for reinforced footing, micropiles provided maximum improvement for medium-density sand. The improvement in bearing capacity is approximately 22.2% when the spacing ratio is reduced from 0.5 to 0.3. Also, for an edge distance ratio of 3, the improvement in the bearing capacity ratio is 76% higher than that of unreinforced footing. Multivariate linear regression showed a strong correlation between the experimental and predicted bearing capacity ratio.

Response spectrum method for spatial seismic ground motion

For seismic analysis of wide structures (for example, airports, stadiums, bridges, etc.), it is important to consider the wave seismic motion of the ground with spatial variability. The differential seismic motion is described by the vector field of kinematic parameters at each point of the base. The differential model of seismic excitation is used for structures on a flexible foundation or discrete supports, if the short-length waves (compared to the size of the foundation) are dominated in seismic waves spectrum. Such excitation is accompanied by angular displacements due to uneven translational ground motions, and it is not yet possible to consider using standard seismic analysis. This paper presents a method of differential seismic analysis with the corresponding modification of the response spectrum (RSM) method. The proposed method requires three accelerograms at each reference point. These accelerograms can be obtained during detailed seismic zoning. To illustrate the method, a model of a stadium cover is considered, for which it is important to apply a spatial differential seismic excitation, and some properties of the excitation are described and analyzed.

SHAKING TABLE TEST OF OFFSHORE WIND TURBINE SUPPORTING TOWER

At present, the wind power generation technology develops rapidly. As the main supporting structure of the wind turbine, the safety of the tower structure is very important under the action of earthquake. Since the behavior of this kind of tripod structure has not yet been investigated through shaking table test, a 1∶20 scaled model of offshore tripod supporting structure was tested through seismic shaking table. Subjected to a series of seismic ground motions with three peak acceleration levels of 0.3 g, 0.6 g and 0.9 g, the dynamic characteristics of the model structure and the seismic response were studied. Two support condition sceneries of the foundation for the test model were considered: with supports at 1.3 m high of each pile foundation, and removal of the supports (simulated pile foundation failure). Compared with the case with the foundation support, the dynamic acceleration response of the structure after the removal of the support was slightly reduced, and the decrease in the amplitude of peak acceleration in X and Y directions was 9.87% and 5.40%, respectively. In addition, finite element analysis by ABAQUS was performed to analyze the elastoplastic response of the structure, and the simulation results were compared with the test results. Good agreement was observed between the two results, which validates the results of both the finite element analysis and the shaking table test, and provides a reference for the elastoplastic time history analysis of the prototype structure.

DHA/EPA Improves GLUT4 Translocation, Glycogen Synthesis and Aerobic Glycolysis in Skeletal Muscle of db/db Mice

Abstract Objectives The aim of this study was to investigate the effects of DHA and EPA on glucose metabolism including glucose uptake and disposal in skeletal muscle and C2C12 myotubes. Methods Four-week-old db/db diabetic mice were fed with control diet enriched with DHA/EPA (purity > 99%, 1% wt/wt) for 10 weeks. To further explore the underlying mechanism, C2C12 myotubes were induced insulin resistance by palmitate and treated with 25 and 50 μM DHA/EPA for 24 h after differentiation. Results The untargeted metabolome of skeletal muscle showed BCAAs and other metabolites associated with glycolysis and TCA cycle were altered by DHA/EPA treatment. Further detections revealed DHA/EPA treatment promoted the translocation of GLUT4 via increasing Rab8a and SNAP23 expression, and enhanced the activity of GS and PDH. In vitro, the glucose consumption was improved coupled with promoted Rab8a or SNAP23, and GS and PDH were also activated under DHA/EPA intervention increased glucose consumption via promoted Rab8a and SNAP23. The GS and PDH were also activated, which were in line with the results in vivo. Conclusions Long-term intake of DHA and EPA may have a protective effect on diabetes through promoted GLUT4 translocation, glycogen synthesis and aerobic glycolysis in skeletal muscle.

Fundamental frequencies of bidirectional functionally graded sandwich beams partially supported by foundation using different beam theories

Investigation on the influence of beam theory and partial foundation support on natural frequencies play an important role in design of structures. In this paper, fundamental frequencies of a bidirectional functionally graded sandwich (BFGSW) beam partially supported by an elastic foundation are evaluated using various beam theories. The core of the sandwich beam is homogeneous while its two face sheets are made from three distinct materials with material properties varying in both the length and thickness directions by power gradation laws. The finite element method is employed to derive equation of motion and to compute the frequencies of the beam. The effects of the material gradation, the foundation parameters and the span to height ratio on the frequencies are studied in detail and highlighted. The difference of the frequencies obtained by different beam theories is also examined and discussed. The numerical results of the paper are useful in designing BFGSW beams with desired fundamantal frequencies.

Serving the Vulnerable While Being Vulnerable: Organizing Resilience in a Social Welfare Sector

The interplay between formal organizing structures and the informal social networks of employees and organizations furthers the resilience of nonprofit organizations that serve the community. This case study draws on qualitative multi-pronged data collected in the aftermath of Hurricane Harvey from two faith networks of social welfare organizations serving the vulnerable in Houston, Texas. Results show that hybrid organizing of formal structures and informal networks contributes to organizational and community resilience. By examining both forms of organizing, this article shows how formal structures offer foundational support to the more informal and nimble social networks across the interorganizational partnerships that support the community. As such, this study extends the process orientation toward resilience by documenting how individuals, organizations, and networks expand organizational internal capacities through disaster relief efforts enacted across levels (employee–organization–community).

Examination of thermal postbuckling of temperature dependent FG-GRMMC laminated beams with negative Poisson’s ratio on elastic foundations

This paper examines the in-plane negative Poisson’s ratio (NPR) effect on the thermal postbuckling of graphene-reinforced metal matrix composite (GRMMC) laminated beams subjected to a uniform temperature rise and supported by an elastic foundation. GRMMC layers having different graphene volume fractions can facilitate the formation of functionally graded (FG) patterns of the beams. The temperature-dependent material properties of GRMMC layers can be estimated by a nonlinear function of temperature from the results of the molecular dynamics simulations. The governing equations for the beam thermal postbuckling problem can be derived based on a higher order shear deformation beam theory and solved by applying the two-step perturbation approach. The von Kármán geometric nonlinearity, the elastic foundation support and the thermal effect are considered in the modeling. Numerical investigations are carried out for (10/-10/10/-10/10)S and (10/-10/10)S GRMMC beams with in-plane NPR. The results show that the buckling temperature of (10/-10/10)S UD beam is slightly higher than that of (10/-10/10/-10/10)S UD beam. The thermal postbuckling capacity for the (10/-10/10)S FG-X beam becomes much higher than that of the (10/-10/10/-10/10)S FG-X beam, when the beam deflection is sufficiently large.

Prevalence and predictors of cognitive impairment among the elderly in Bangladesh

To investigate the prevalence of cognitive impairment and its predictors among the elderly in Bangladesh. We use a cross-sectional survey of 1015 older people (≥60 years) in Bangladesh collected jointly by the Sir William Beveridge Foundation (SWBF) and Aging Support Forum (ASF), Bangladesh. The Mini-Mental State Examination (MMSE) scale, adapted to the Bengali language, was used for assessing cognitive impairment, which was available for 111 participants. Logistic regression analysis was used to identify predictors of cognitive impairment. Multiple imputation under the missing-at-random (MAR) mechanism was used to deal with missing data. Overall, 31 out of 111 (27.9%) participants had mild, moderate or severe cognitive impairment, with a higher proportion among women (33.3%, 17 out of 51) than men (23.3%, 14 out of 60). More precisely, 24 out of 111 (21.6%) and 7 out of 111 (6.3%) had mild/moderate and severe cognitive impairment, respectively, with a higher percentage among women (mild/moderate: 25.5%, severe: 7.8%) than men (mild/moderate: 18.3%, severe: 5.0%). Age (odds ratio, OR = 1.06, p = 0.046, 95% CI: 1.001 to 1.119) and social engagement (OR = 0.25, p = 0.033, 95% CI: 0.072 to 0.898) were found to be statistically significant predictors of cognitive impairment in this group of people. The effect of physical disability fell short of statistical significance at the 5% level but was significant at the 10% level (OR = 2.89, p = 0.099, 90% CI: 0.999 to 8.370). The prevalence of cognitive impairment in Bangladesh is alarming and is comparatively higher among elderly women, which seems to increase with age and the presence of any physical disability. Also, prevalence appears to be lower in people who are more socially engaged or active.

A review of Leila Rose Foundation support for families affected by rare childhood cancer in Australia over the past decade.

BackgroundThe Leila Rose Foundation (“the Foundation”) was established in April 2011, to address financial toxicity as well as the gaps in knowledge and support for families affected by a rare childhood cancer diagnosis in Australia.AimThe aim of this brief report is to analyze the diagnostic trends surrounding the rare cancer diagnoses for patients referred to the Foundation over the past decade and to present case studies evaluating the role of the Foundation's Family Support Coordinator in providing tailored, individualized support for families.MethodsEligibility for family support is restricted to children ≤ 14 years of age at diagnosis with a cancer that has an incidence less than 5% of all childhood cancers in Australia as reflected by national registry data. The analysis of diagnostic trends in this report, was based upon a systematic review of enrolment records. The role of the Family Support Coordinator is presented in four different case studies.ResultsAs at 1 November 2020, the Foundation has supported 197 families affected by rare childhood cancer. Financial support of $825,000 has been provided directly to these families. Enrollment records demonstrate that 35 patients representing 18% of all enrollments have had a unique diagnosis that has not been recorded for any other enrolled patient highlighting that these diagnoses are very rare. The most frequent diagnoses have included Medulloblastoma, Ewing's Sarcoma and Wilm's Tumor (20, 19, 19 patients respectively). The Family Support Coordinator role has provided individualized support for families which has been greatly appreciated based upon ad hoc family feedback.ConclusionsChallenges remain in terms of improving outcomes for families affected by rare childhood cancer. The Foundation is committed to leaving no stone unturned and delivering its unique support services to families in order to reduce the burden caused by a rare childhood cancer diagnosis both now and in the future.

Mechanical properties of a new string capsule drainage anchor and its supporting effect in deep foundation pit

With the increase of the scale and depth of urban underground space construction in coastal soft soil area, the traditional anchoring technology has been difficult to meet the requirements of deep foundation pit excavation and support. This paper puts forward a new type of string capsule drainage anchor supporting structure, introduces its structure composition, analyzes its working mechanism and mechanical characteristics, the calculation formula of ultimate bearing capacity of small cylindrical shear failure between anchor and surrounding soil is given, finally, the supporting effect of the new structure in deep foundation pit engineering is simulated and analyzed by finite element software. It is concluded that the stress of the new type of anchor can be divided into three stages: static earth pressure, plastic zone development and plastic zone breaks through; the new anchor can quickly dissipate the pore water pressure in the surrounding soil, which is more conducive to the stability of foundation pit; the axial force distribution presents a “sawtooth” shape, and the axial force increases sharply in the expanding section; the supporting effect of the new anchor is more obvious than that of the traditional anchor, which can more effectively inhibit the horizontal displacement of the slope.

Novel method for stress history analysis in normally consolidated clays

The historical investigation of stresses in a clay material is essential to predict the compressible behaviour of a soil layer that, in most cases functions as a foundation support of superstructures. Because the stresses underwent in the geological past provide useful information to understand the response of the soil today. There are numerous methods for the interpretation of the preconsolidation stress, defined by the standard unidimensional consolidation test. The concept of preconsolidation stress is extremely useful in the geotechnical field to analyze and estimate settlements in a clay deposit, in addition to normalizing other parameters for comparative purposes. Through mineralogical analysis and consolidation tests based on different models for the estimation of the vertical consolidation coefficient, preconsolidation stress is evaluated by applying disparate constitutive methods. In order to observe the dispersion of results for a particular soil. A new technique is proposed for the determination of the preconsolidation stress prescribed in differential terms and with a high degree of objective interpretation.

Integrating Pavement Sensing Data for Pavement Condition Evaluation.

Highway pavements are usually monitored in terms of their surface performance assessment, since the major cause that triggers maintenance is reduced pavement serviceability due to surface distresses, excessive pavement unevenness and/or texture loss. A common way to detect pavement surface condition is by the use of vehicle-mounted laser sensors that can rapidly scan huge roadway networks at traffic speeds without the need for traffic interventions. However, excessive roughness might sometimes indicate structural issues within one or more pavement layers or even issues within the pavement foundation support. The stand-alone use of laser profilers cannot provide the related agencies with information on what leads to roughness issues. Contrariwise, the integration of multiple non-destructive data leads to a more representative assessment of pavement condition and enables a more rational pavement management and decision-making. This research deals with an integration approach that primarily combines pavement sensing profile and deflectometric data and further evaluates indications of increased pavement roughness. In particular, data including Falling Weight Deflectometer (FWD) and Road Surface Profiler (RSP) measurements are used in conjunction with additional geophysical inspection data from Ground Penetrating Radar (GPR). Based on pavement response modelling, a promising potential is shown that could proactively assist the related agencies in the framework of transport infrastructure health monitoring.

The Lithofacies Classification and Its Influence on the Gas Production Capacity in the Shale Gas Production Area

The gas production capacity difference among single wells and the difficulties in sustaining stable production are the key problems faced by shale gas production areas. Based on the typical characteristics of the shale gas production areas， a technical process for the lithofacies classification of high-quality marine shale affected by the gas production capacity was established in this paper. Firstly， for the high-quality marine shale in the shale gas production area， the main gas production capacity difference control factors were analyzed， and the lithofacies classification scheme was determined. Then， using the developed logging calculation model of total organic carbon （TOC） content， porosity， clay， siliceous， and calcareous mineral content， the single well parameter calculation and the lithofacies identification in one shale gas producing area were completed. A total of 10 types of shale lithofacies were identified in one shale gas production area， and the relationship between shale lithofacies type and gas production capacity difference was revealed by comparing the gas content of each lithofacies. Finally， a three-dimensional （3D） lithofacies model in one shale gas production area was established by using the truncated Gaussian simulation algorithm and the sedimentary microfacies confined lithofacies strategies， the spatial distribution characteristics of each kind of lithofacies were shown， and the gas production capacity difference in the Wufeng-Longmaxi black shale in the study area was revealed. At the same time， according to the two conditions of large volume proportion and great gas potential in 3D space， the three different lithofacies with excellent gas production capacity in the study area were determined as i. rich in carbon， high in porosity， calcium， muddy siliceous shale， ii. rich in both carbon and porosity mixed shale， and iii. high in carbon， medium to high in porosity， calcium， muddy siliceous shale. The above results are helpful for explaining the essential causes for the great difference in the decline amplitude and output effect of shale gas production areas， laying a solid theory foundation and technical support for fine production management in shale gas production areas.

A Literature Review of Hybrid System Dynamics and Agent-Based Modeling in a Produced Water Management Context

This paper explores the possibility and plausibility of developing a hybrid simulation method combining agent-based (AB) and system dynamics (SD) modeling to address the case study of produced water management (PWM). In southeastern New Mexico, the oil and gas industry generates large volumes of produced water, while at the same time, freshwater resources are scarce. Single-method models are unable to capture the dynamic impacts of PWM on the water budget at both the local and regional levels, hence the need for a more complex hybrid approach. We used the literature, information characterizing produced water in New Mexico, and our preliminary interviews with subject matter experts to develop this framework. We then conducted a systematic literature review to summarize state-of-the-art of hybrid modeling methodologies and techniques. Our research revealed that there is a small but growing volume of hybrid modeling research that could provide some foundational support for modelers interested in hybrid modeling approaches for complex natural resource management issues. We categorized these efforts into four classes based on their approaches to hybrid modeling. It appears that, among these classes, PWM requires the most sophisticated approach, indicating that PWM modelers will need to face serious challenges and break new ground in this realm.

Measles Vaccination in the Presence of Maternal Measles Antibody Reduces All-Cause Child Mortality - A Planned Cohort Study Nested in a Randomised Trial

Background: Several smaller studies suggested that measles vaccination (MV) in the presence of maternal measles antibody (MatAb) reduces all-cause mortality. We tested the hypothesis that children receiving early MV at 4 months in the presence of MatAb would have 35% lower mortality than children receiving MV at 4 months with no detectable MatAb. We further hypothesised that among children, who did not receive early MV, there would be no difference in mortality between those with and without MatAb. Methods: The study was an observational study nested within a randomised controlled trial (RCT) of early MV, carried out in Guinea-Bissau from 2011-2019. The RCT compared the mortality between 4 and 60 months of age for children randomised 2:1 to two doses of MV at 4 and 9 months of age or to only one dose of MV at 9 months of age. At enrolment in the RCT, a blood sample was collected from all children. A multiplex immunoassay was used to determine the measles MatAb level; as control exposures, levels of varicella, mumps and rubella antibody were assessed. We assessed overall mortality as a function of randomisation group and presence of MatAb in Cox proportional hazards models. Results: 6,598 children were enrolled in the RCT, 6,239 (95%) had a valid enrolment blood sample. In children receiving early MV at enrolment, mortality was 50% (95% CI: 20-68%) lower for those vaccinated in the presence of MatAb (n=3132; 51 died) compared with those vaccinated in the presence of no MatAb (n=1028, 31 died). There was no beneficial effect of having MatAb in children who did not receive early MV (test of interaction, p=0.045). The result was specific for measles antibody; no effect was found for varicella, mumps or rubella antibodies. In a meta-analysis of five available studies, MV in the presence of MatAb was consistently associated with lower mortality compared with MV in the absence of MatAb, the combined meta-estimate indicating 55% (35-68%) lower mortality. Interpretation: The results support the previous findings that MV in the presence of maternal antibody enhances the beneficial effects of MV on child survival. Earlier measles vaccination should be considered. Further research is needed to examine whether it is beneficial to vaccinate women of fertile age to transfer higher level of maternal antibodies to their children. Trial Registration (for the RCT): NCT01486355 Funding: The RCT was funded by an ERC Starting Grant to Christine S Benn (ERC-2009-StG-243149) and by a “Center of Excellence” grant from the Danish National Research Foundation (DNRF108). The work on non-specific effects of vaccines has been supported by the Danish Council for Development Research, Ministry of Foreign Affairs, Denmark [grant number 104.Dan.8.f.], Novo Nordisk Foundation and European Union FP7 support for OPTIMUNISE (grant: Health-F3-2011-261375). The funding agencies had no role in the study design, data collection, data analysis, data interpretation, or the writing of the report. Declaration of Interests: Authors declare no competing interests. Ethics Approval Statement: The protocol was approved by the National Ethical Committee in Guinea-Bissau and given consultative approval by the Danish Central Ethical Committee

Genius fails to appear: the Atlantic Awards in literature, 1946–1950

ABSTRACT A recurring problem in arts policy concerns support for individual artists and authors. The Atlantic Awards in Literature, a little-known experiment by the Rockefeller Foundation in the years immediately following the second world war, aimed to encourage younger British writers whose careers had been interrupted by the war. By the end of the five-year grant period, a total of 58 authors had received support; among the best-known perhaps were W.S. Graham, Kathleen Raine, Laurie Lee, Philip Toynbee, and Robert Kee. Although the Rockefeller Foundation considered its initial grant a success and indeed renewed support for the project in 1948, no British patrons agreed to continue the project and critical opinion about postwar literary work remains largely unfavorable. Despite this apparent failure, the Atlantic Awards may have had a lasting impact on the evolution of American support for creative writing and the arts. The Rockefeller Foundation soon provided grants for fellowships to leading American literary reviews and to the creative writing program at the University of Iowa. In this respect, the Atlantic Awards pointed the way to increased foundation support for creative writing and the arts at a time when the federal government provided no direct support for the arts in the United States.

Revised Child Anxiety and Depression Scale: a Psychometric Examination in Chinese Youth

There remains a need for a disorder-specific inventory of children’s depression and anxiety that can reliably screen anxious and depressive disorder symptomatology in Chinese children. The Revised Child and Anxiety Depression Scale (RCADS) is a self-report questionnaire assessing anxiety and depression in children (Chorpita et al., 2000; Piqueras et al., 2017). This study sought to evaluate its psychometric properties in a Mainland Chinese sample. Students from the 4th to 11th grades (N = 1001) participated in this study. Each of the RCADS subscales, by age and sex, possessed reliability coefficients ranging between .63 and .81. Means and standard deviations for RCADS subscales calculated for the age and sex sub-samples were reported. Participants reported slightly lower levels on five subscales than for Chorpita et al. (2000) normative sample. The scales were significantly and strongly correlated with the Child Behavior Checklist (CBCL) subscales (somatic, withdrawal, anxiety) as well as CBCL internalizing scores. Fit statistics suggested marginal to adequate fit for the six-factor model for the Chinese youth. The present study provides foundational support for the psychometric properties of the RCADS in a large sample of Chinese youth yet indicates that factor structure might be improved through enhanced sampling of culturally relevant symptom expressions.
