Market convergence challenges socially sustainable supply chain management (SSSCM) due to the increasing competition. Identifying market convergence trends allows companies to respond quickly to market changes and improve supply chain resilience (SCR). Conventional approaches are one-sided and biased and cannot predict market convergence trends comprehensively and accurately. To address this issue, we propose a framework based on info2vec that solves the problem of matching multidimensional data by using the technology layer as the focal layer and the supply chain as the supporting layer. The framework enriches the supply chain dimension with the technology dimension. A knowledge graph is constructed to facilitate cross-domain information connectivity by integrating different data sources. The nodes in the knowledge graph were characterized using a representation learning algorithm, which enhanced feature mining during supply chain and market convergence. Changes in market demand were predicted based on link prediction experiments. Market convergence has an impact on firm cooperation and, thus, on SCR. The framework recommends potential technological and innovative cooperation opportunities for firms. In this way, it has been demonstrated to improve SSSCM through network resilience experiments. This method predicts market convergence efficiently based on the supply chain knowledge graph, which provides decision support for enterprise development. [ABSTRACT FROM AUTHOR]

Recently, in the concrete field, the use of industrial wastes for concrete materials is expected for environmental reasons. However, these wastes may contain hazardous heavy metals. It is well known that cement paste has an ability to fix heavy metal ions, whereas it was also found that absorbed heavy metal ions can easily leach from cement paste in the presence of a CaCl2 solution. The present study aims to investigate the lead leaching behaviours from hardened cement pastes in various chloride solutions by tank leaching tests. The water-to-cement ratios of the cement paste specimens were 0.40 and 0.55. Lead was added to the cement pastes at 1 mass% of cement. Each chloride solution for the tank leaching test had three kinds of concentrations (5%, 10%, and 20%). After the tank leaching tests, the chemical changes of the specimens were analysed to discuss the effect of co-existing ions in the solutions. The results indicate that the cumulative lead leaching amount is related to the types of chloride solution as well as the concentrations of the solutions. The lead leaching amount in the CaCl2 solution was much higher than that in other solutions.

ABO3−δ perovskites are ideal for high‐temperature thermochemical air separation for oxygen production because their oxygen nonstoichiometry δ can be varied in response to changes in temperature and oxygen partial pressure [pO2 ]. Herein, the outstanding oxygen‐sorption performance of CaCoxZr1−xO3−δ perovskites and their potential application as oxygen‐selective sorbents for air separation is reported. In situ thermal X‐ray diffraction was used to study the materials' structural changes in response to temperature variations in air and inert atmosphere. Temperature‐programmed reduction was employed to elucidate the relationship between perovskite composition and redox property. O2 sorption performance was evaluated by isothermal analyses at various temperature and pO2 along with long‐term absorption–desorption cycle tests. The high oxygen‐sorption capacity was mainly attributed to Co at B‐site, whereas partial substitution of Co by Zr enhanced the structural crystallinity and thermal stability of the perovskite. A stable oxygen production of 2.87 wt % was observed at 900 °C during 5 min‐sorption cycles for 100 cycles. [ABSTRACT FROM AUTHOR]

People's subjective well-being (SWB) is a key indicator when evaluating whether social and economic policies are successful or not. The open policy and reform have been in practice for more than 30 years now, China's economy has sustained rapid growth, and people's incomes are on continuous rise. Economic growth is supposed to enhance the SWB of people. However, people do not feel the expected happiness due to many social phenomena of the transition period. That economic development and citizen's SWB are not related, and even reversely related, is a common problem in the current urban economic and social development in China. A meaningful topic worth discussion is how the government can promote SWB of its people. With the national data from CGSS2006 of the macro-tax burden, public expenditure, local governments' revenue disparities, and people's SWB, this study empirically tested their relationships. It was found that: (1) macro-tax burden had a significant negative impact on people's SWB; (2) overall, public spending was positive correlated with SWB; (3) in the area of public spending, local governments' infrastructural investment negative correlated with SWB, whereas their investments in science, education and social security positively correlated with SWB; and (4) expenditures on science, education and social security had different impact on the SWB of the local citizens and non-local residents. Based on these empirical findings, regulating governments' expenditure and infrastructural investment, exercising structural tax reduction, and increasing the proportion of the public expenditure would be highly important to narrowing income gaps and improving people's satisfaction of life. It would be necessary to push the government to be transformed into the government oriented toward public service. [ABSTRACT FROM AUTHOR]

Purpose: To observe the changes of macular thickness in patients with sleep apnea syndrome (SAS) before and after sleep., Methods: Thirty-two patients (63 eyes) diagnosed as SAS from August 2003 to January 2007 were enrolled. Macular thickness were measured using optical coherence tomography (OCT) at 11:00 to 12:00 evening (before sleep)and 20 to 30 minute after sleep, respectively., Results: The mean macular thickness was (123.00+/-19.98)um and (134.25+/-19.92)um before and after sleep, respectively. The mean difference was (11.25+/-9.04)um before and after sleep(t=9.878,p<0.05),95%CI(8.98,13.53)um., Conclusions: The macular thickness of SAS is increased in SAS patients, which may due to anoxia of SAS.
