Spatio-temporal analysis of water sustainability of cities in the Yangtze River Economic Belt based on the perspectives of quantity-quality-benefit

An integrated water sustainability assessment is conducive to realizing the optimal allocation and efficient water utilization, and alleviating the water crisis. Existing research mainly appraises water quantity and water quality as unidimensional or in combination, without considering the water benefit, and few studies have assessed the regional water sustainability based on an integrated evaluation multidimensionally. Therefore, this paper innovatively introduces water benefit to construct a three-dimensional quantity-quality-benefit model (QQBM) to evaluate water sustainability in line with the water footprint (WF) theory and water resources balance sheet (WRBS). The impact of the coupled coordination relationship among water quantity, water quality, and water benefit on the water sustainability evaluation is further analyzed by introducing the coupled coordination degree model (CCDM). This paper takes the Yangtze River Economic Belt (YREB) as an example and makes a spatio-temporal analysis of the water sustainability in its 11 provincial capitals during 2010-2021 from a single dimension and a three-dimensional perspective, respectively. The results found that: (1) From a single dimension, the water sustainability in the 11 provincial capitals in the YREB during 2010-2021 is at a medium level, with better water benefit sustainability, moderate water quantity sustainability, and horrendous water quality sustainability. Among them, the water sustainability is the best in Guiyang and Hangzhou, while the worst in Shanghai. (2) From a three-dimensional perspective, the water sustainability in the 11 provincial capitals from 2010 to 2021 is horrific. Among them, the water sustainability is the best in Kunming, Changsha, Nanjing and Shanghai, while the worst in Wuhan and Hefei. (3) The degree of coupling coordination between water quantity, water quality and water benefit significantly influence the water sustainability in the 11 provincial capitals of the YREB. The three-dimensional assessment model QQBM constructed in this study is more comprehensive and objective than the single perspective assessment. The findings in this paper can help other regions to conduct similar water sustainability assessments and inform policy recommendations.

National resilience assessment and improvement based on multi-source data: Evidence from countries along the belt and road

National resilience is a consensus benchmark to characterize the ability of disaster resistance of a country. The occurrence of various disasters and the ravages of COVID-19 have created urgent needs in assessing and improving the national resilience of countries, especially for countries along the Belt and Road (i.e., B&R countries) with multiple disasters with high frequency and great losses. To accurately depict the national resilience profile, a three-dimensional assessment model based on multi-source data is proposed, where the diversity of losses, fusion utilization of disaster and macro-indicator data, and several refined elements are involved. Using the proposed assessment model, the national resilience of 64 B&R countries is clarified based on more than 13,000 records involving 17 types of disasters and 5 macro-indicators. However, their assessment results are not optimistic, the dimensional resilience are generally trend-synchronized and individual difference in a single dimension, and approximately one-half of countries do not obtain resilience growth over time. To further explore the applicable solutions for national resilience improvement, a coefficient-adjusted stepwise regression model with 20 macro-indicator regressors is developed based on more than 19,000 records. This study provides the quantified model support and a solution reference for national resilience assessment and improvement, which contributes to addressing the global national resilience deficit and promoting the high-quality development of B&R construction.

Construction of an evaluation index system of nursing quality for pressure injury in Operating Room

Objective To construct an evaluation index system of nursing quality for pressure injury in Operating Room based on Donabedian structure-process-outcome three-dimensional quality assessment model to provide a reference for nursing quality assessment by nursing managers in Operating Room. Methods From March to July 2018, we selected 18 experts such as chairman of Committee of Operating Room of Shanghai Nursing Association, head nurses of Operating Room at ClassⅢ Grade A general hospitals in Shanghai, nurse specialist of pressure injury management team, by purposive sampling as subjects. The consultation form was designed based on search of operation related pressure injury at home and abroad as well as Donabedian structure-process-outcome three-dimensional quality assessment model. Delphi method was used to 2 rounds of expert consultation. Items in all levels were deleted, merged and revised according to expert opinions and to define the evaluation indexes in all levels of nursing quality for pressure injury in Operating Room as well as the weight. Results This study carried out 2 rounds of expert consultation, with 0.989 for the expert judgment coefficient, 0.956 for the expert familiarity coefficient and 0.973 for the expert authority coefficient. The variation coefficients of second-level indexes and third-level indexes ranged from 0.109 to 0.138 in 2 rounds of expert consultation. The evaluation index system of nursing quality for pressure injury in Operating Room included 3 first-level indexes, 9 second-level indexes and 28 third-level indexes. Conclusions This study constructs a scientific and reasonable evaluation index system of nursing quality for pressure injury in Operating Room with the method of Delphi which can be used to nursing quality assessment for pressure injury in Operating Room and is in favor of continuous quality improvement of nursing in Operating Room. Key words: Operating Room; Pressure injury; Nursing quality; Evaluation index; Delphi methods; Expert consultation; Three-dimensional quality assessment model

Construction of nursing quality evaluation criteria for operating theatre basing on the three-dimensional quality assessment model

Objective To construct nursing quality evaluation criteria for operating theatres, basing on the three-dimensional quality assessment model, so as to provide scientific basis for objectively evaluating the quality of care in operating rooms. Methods From August to November 2016, a total of 30 medical and nursing specialists from the 2nd Affiliated Hospital of Harbin Medical University were investigated with two rounds of questionnaires by Delphi method, in order to construct the nursing room quality evaluation standard. Results The response rates of the two rounds of questionnaires were 93.33% and 100.00%. The authority coefficient (Cr) of the experts was 0.87 and the degree of expert coordination was good (P<0.001) . The final operating room care quality evaluation criteria include 3 one-level indicators, 19 two-level indicators, and 51 three-level indicators. Conclusions The final nursing quality evaluation criteria were reliable and valid, which can provide standard for the nursing quality evaluation and management of operating room. Key words: Operating rooms; Three-dimensional quality assessment model; Delphi

Perception of family social climate and attitudes towards bullying in adolescents

The involvement of family factors in the problem of bullying is well documented, not only in terms of the various differential profiles presented by bullies and their victims in terms of parental socialization styles, but the implications are derived from the perception of family climate. Specifically, this study provides an analysis of the relationship between psychosocial perception of family social climate by a group of 550 adolescents of the Principality of Asturias (Spain) (278 girls and 272 boys 50.5%, 49.5%) and their attitudes to bullying according to a three-dimensional assessment model (planes cognitive, affective and dispositional) measures through Attitudes toward Social Aggression Scale constructed ad hoc by the authors (Moral, 2005). It has been confirmed that adolescents with more favorable attitudes to violence perceived peer more conflictual family climate, feel less affection in family relationships, express greater difficulty communicating with them, and less respect for their opinions and paternal highest demands and declared to be subject to physical and psychological punishment by their parents compared to those adolescents with more negative attitudes towards bullying violence.
