Living arrangements and support resources for China’s elderly: findings from CLHLS 2018

The 2018 Chinese Longitudinal Healthy Longevity Survey(CLHLS)presents infor-mation on both individual characteristics and family characteristics of China’s elderly population.It shows that only 1%of elderly men and 0.1%of elderly women never married.Older elderly people had more children than younger elderly people on average.Younger elderly had more years of schooling on average than did the older elderly population.Elderly women were more likely than elderly men to rely on their children as the main source of their income.Eighty-four point six percent of elderly people lived with household members,13.5%lived alone and 1.9%lived in institutions.Younger elderly people preferred to live alone(or with spouse only)more than did older elderly people.Family members offered the elderly the most in the way of emotional support and comfort,while people other than friends or neigh-bors play a very limited role.

Multi-objective optimization of process based on resource capability

To improve the practicability, suitability and accuracy of the trade-off among time, cost and quality of a process, a method based on resource capability is introduced. Through analyzing the relationship between an activity and its’ supporting resource, the model trades off the time, cost and quality by changing intensity of labor or changing the types of supporting resource or units of labor of resource in a certain time respectively according to the different types of its’ supporting resources. Through contrasting this method with the model of unit time cost corresponding to different quality levels and inter-related linear programming model of time, cost and quality for process optimizing, it is shown that this model does not only cover the above two models but also can describe some conditions the above two models can not express. The method supports to select different function to optimize a process according to different types of its supporting resource.

From institutional merger integration to institutional strategic transformation:A case study of the strategic management paradigm at Shanghai Library

This article attempts to apply the strategic management theory to the subsequent shaping up of a readjusted strategic development policy for Shanghai Library after its merger with the Institute of Scientific and Technological Information of Shanghai(ISTIS)in 1995.It also tries to analyze and explicate such an empirical implementation of institutional reintegration process through strategic management at Shanghai Metropolitan Library.By doing so,it aims to present an objective case study of activities based on the strategic management paradigm at a major Chinese metropolitan public library.

Using Linked Data in a heterogeneous Sensor Web: challenges, experiments and lessons learned

Abundant sensor data are now available online from a wealth of sources,which greatly enhance research efforts on the Digital Earth.The combination of distributed sensor networks and expanding citizen-sensing capabilities provides a more synchronized image of earth’s social and physical landscapes.However,it remains difficult for researchers to use such heterogeneous Sensor Webs for scientific applications since data are published by following different standards and protocols and are in arbitrary formats.In this paper,we investigate the core challenges faced when consuming multiple sources for environmental applications using the Linked Data approach.We design and implement a system to achieve better data interoperability and integration by republishing real-world data into linked geo-sensor data.Our contributions include presenting:(1)best practices of re-using and matching the W3C Semantic Sensor Network(SSN)ontology and other popular ontologies for heterogeneous data modeling in the water resources application domain,(2)a newly developed spatial analysis tool for creating links,and(3)a set of RESTful OGC Sensor Observation Service(SOS)like Linked Data APIs.Our results show how a Linked Sensor Web can be built and used within the integrated water resource decision support application domain.
