Construction of Urban Mixed-age Community: Opportunities, Challenges and Countermeasures: A Case Study of“Fangjia Hutong”in Beijing

In the context of China’s economic development and population aging,the innovation and exploration of the old-age care model has emerged as a new community transformation and development direction.Given the differing needs and characteristics of individuals across the lifespan,it is evident that a design approach that incorporates mixed-age integration and mutual-help communities is a viable strategy for enhancing intergenerational exchanges.This entails the creation of a diverse and open community that is conducive to habitation for individuals of all ages,encompassing the full spectrum of needs,from those of young children to the elderly.Such a community must be designed and constructed with the population in mind,from the initial planning and design stages to the operational phase.This encompasses a comprehensive range of services,including food,clothing,housing,transportation,and medical care and recreation.

Study on Planning Model of Chinese Aged Community in Background of European and American Old-age System

Attention to the pension work is the performance of social development and progress, effective selection of effective old-age way to promote the elderly in his later years and it is the inevitable requirement of the development of the times. On the basis of comparative analysis of the pros and cons of various pension methods, the actual social work department must carry out specific judgment on the specificold people. The elderly need not only the material aspects of life care, but also the need for emotional support and spiritual comfort, in the new historical conditions must be in the body and mind and informed lines and other aspects of the elderly to give loved ones, considerate, warm and friendly , respect and care. This paper proposes the novel perspective on the planning model of Chinese aged community in background of European and American old-age system. In the future, we will apply the proposed model into more scenarios to test the performance.

Construction of Xi'an ecological old-age care community in the new urbanization

The new urbanization is an important carrier of ecological civilization construction, and ecological old-age care is the concrete manifestation of the perfect combination of the two, the proper meaning of the new urbanization connotation and an inevitable trend of its development. Based on the analysis of the connotation and relationship between the new urbanization and ecological old-age care, together with the current situation and existing problems of the current nursing institutions and ecological old-age care in Xi'an area, this paper discusses the major issues that should be noticed when constructing the ecological old-age care community in Xi'an and three main construction modes.

Analysis of home care-based multi-level old-age service system

With the deepening of China＇s aging, China＇s social pension problem more obvious each day, and gradually become the focus of attention of the whole society. On the one hand, China entered the aging society, old-age needs to grow exponentially. The sixth national census shows that in our country, the population aged 60 and 13.26% of the total population over the total number of 179 million, 65 years and older the proportion of 8.87% of the total population, the absolute number of nearly 120 million. Hundreds of millions of older age groups will produce a growing demand for care services, which is the original old-age service system and the whole economic and social development is a huge pressure. On the other hand, with the economic and social transformation, the traditional model of family pension has been unable to adapt to the profound changes in modem employment, family structure, the concept of retirement, since most parts of China, ＂old before getting ricE＂ the situation, how to solve the elderly the pension problem is related to the overall situation of China＇s economic and social development, related to the overall situation of building a harmonious society in China. Under current national conditions, the emphasis on the development of a single individual body to meet the growing demand for pension service is not realistic, we must mobilize the enthusiasm of all aspects of the element, multi-service integration of resources subject to their commitment to a different responsibilities and tasks provide a full range of care services according to different types, different levels of the actual needs of the older age groups. On the aging problem is that the whole community to face, you need to multi-government body, families, communities, institutions combine effectively starting from the actual needs of the elderly population, according to the financial assistance, life care, spiritual consolation three set the specific needs of services, through a government-led, home-based care services, community care services for the core and supplementary services for institutions focused on pension and other means to provide a full range of pension services.

Techno-Financial Analysis of Energy Access through Hybrid System with Solar PV under the Various Rural Community Models for State of Uttarakhand, India

Uttarakhand state comes under special category state where approximately 69.45% population lived in rural area under the population density with varied range of 37 to 607 persons per sq.km. Although Uttarakhand is having per capita consumption of 1112.29 kWh which is higher than national average per capita consumption of 779 kWh as till date, but remote communities, villages are not able to access clean, cheep and good quality of energy due to uneven terrain, lack of proper transmission & distribution lines [1]. 100% villages are electrified under the RGGVY scheme as per the Ministry of Power Government of India, but due to poor loading of transformer, lack of grid infrastructure and natural calamities, remote house owners are not able to get good quality of power thus affect the livelihood and source of income generation in various means [2]. As Uttarakhand state having future plans to be make state energy sufficient and energy access to all by year 2016-2017, so major ground level initiative have been taken by Government of Uttarakhand. The government of Uttarakhand has incorporated innovative business model to provide good quality of power with non-conventional energy source. Under the initiative invlovement of local people and village level, panchayats have ownership and responsibility to operate these clean energy business model to improve livelihood in remote hilly places of Uttarakhand. Under this analysis, five different type of community models are categorized as Community 1, Community 2, Community 3, Standalone 1 & Standalone 2 for rural &remote communities based on number of unclustered households with the distance covered between 200 m to 20 km, and electrical loads i.e. lighting, fan, mobile chargers, television along with time of day energy consumption patterns. These community models are for remote hilly location where grid integration and distribution lines are not feasible to built due to hilly terrain, low soil strength and huge expenses for expanding power cables for supplying good quality power. The preliminary studies and simulations has been done in HOMER tool by considering the various composite source of power, i.e. Solar PV with battery bank, Solar PV with battery Bank & Generator, and Solar PV along with DG. These three hybrid source of power generation with Solar PV as base source under five different community models, the techno-commercial feasibility has been analyzed in terms of load sharing proposition with Solar PV and battery, DG, Energy production through PV, load consumption per year, Excess and unmet energy monitoring, battery sizing to meet the load during nights, DG operation when the solar energy not available due to weather condition and non availability of sunshine in night. Financial feasibility has been examined in terms of levelized cost of energy, cost summary and O&M cost per year of three integrated sources of energy generation with Solar PV under each community model. Solar PV power plant , which is the best renewable source of energy to cater energy access issue in remote hilly places. The Uttarakhand receives good amout of daily average radiation level of 5.14 - 5.50 kWh/m2/day. Financial feasible community models for different hilly region based on their energy consumption need to be implemented with the help of local community by providing ownership to local people, panchayat, for it not only caters energy access issue but also provides clean, cheep, uninterruptable energy and improves livelihood standard to locals by engaging them into operation maintenance and tariff or rent collection. The study shows that Solar PV power plant with battery bank is the optimal solution considering life cycle cost of hybrid system. It is feasible due to low operation and maintenance cost, price declination of battery and Solar PV module, battery prices at time of replacement.

Bacterial community succession in response to dissolved organic matter released from live jellyfish

Jellyfish blooms have increased worldwide, and the outbreaks of jellyfish population not only affect the food web structures via voracious predation but also play an important role in the dynamics of nutrients and oxygen in planktonic food webs. However, it remains unclear whether specific carbon compounds released through jellyfish metabolic processes have the potential to shape bacterial community composition. Therefore, in this study, we aimed to investigate the compositional succession of the bacterioplankton community in response to the dissolved organic matter (DOM) released by the live Scyphomedusae Cyanea lamarckii and Chrysaora hysoscella collected from Helgoland Roads of the North Sea. The bacterial community was significantly stimulated by the DOM released form live jellyfish and different dominant phylotypes were observed for these two Scyphomedusae species. Furthermore, the bacterial community structures in the different DOM sources, jellyfish-incubated media, Kabeltonne seawater, and artificial seawater (DOM-free) were significantly different, as revealed by automated ribosomal intergenic spacer analysis fingerprints. Catalyzed reporter deposition fluorescence in situ hybridization (CARD-FISH) revealed a rapid species-specific shift in bacterial community composition. Gammaproteobacteria dominated the community instead of the Bacteroidetes community for C. lamarckii, whereas Gammaproteobacteria and Bacteroidetes dominated the community for C. hysoscella. The significant differences in the bacterial community composition and succession indicate that the components of the DOM released by jellyfish might differ with jellyfish species.

Shanghai has a Fund for the long-term care insurance system. To compare and analyze the related elements of raising, service content and payment, combined with the experience ol long-term nursing insurance in foreign countries, and considering its application in community pension, it has certain reference significance for the design of long-term nursing insurance system in China.

Angling of hybrid sunfish from a hatchery pond with potential implications for community fisheries

Hatcheries are frequently called upon to produce catchable-sized fish for stocking community fishing ponds.Desirable attributes of fish selected for stocking into community ponds are that they are easy to produce in a hatchery system to sizes anglers are interested in catching and they provide anglers with high catch rates once stocked.Hybrid sunfish[male Bluegill(Lepomis macrochirus)×female Green Sunfish(L.cyanellus)]have attributes that potentially make them attractive for use in community fishing ponds.We assessed initial angler catch rates of 100 stocked hybrid sunfish in a 0.12-ha hatchery pond and after being subjected to angling(four,1-hr catch-and-release fishing events with five anglers).We also investigated whether catch rates would change following a supplemental stocking of an additional 100 hybrid sunfish(four,1-hr catch-and-release fishing events with five anglers).The anal fin of each fish in the second stocking was hole punched to differentiate them from those of the first stocking and fish caught by anglers were hole punched in the caudal fin each time they were caught before being released back into the pond.Angler catch rates were highest during initial fishing events that followed stocking(9.2 fish/angler hr and 18.0 fish/angler hr)and substantially declined in subsequent events(≤3.4 fish/angler hr).Catches of the newly stocked fish and previously stocked fish contributed to the high catch following the supplemental stocking.Most(80%)of the fish were caught in the first 30 min of each event and 45%were caught during the first 10 min.Anglers were able to catch 88%of the fish from the first stocking and 67%from the second stocking at least once.No mortality occurred during the study as all fish were recovered when the pond was drained.Our results suggest that hybrid sunfish will potentially provide high initial catch rates following stocking into community ponds,but managers should expect reduced catch rates following initial fishing even without harvest.Additional stocking will be needed to provide periodic increases in angler catch rates even without harvest.

Why Becoming a B Corp?A Discussion and Some Reflections

In the late 1980s,the prevailing corporate model usually depicted companies as economic entities pursuing shareholders’profit maximisation interests without a thought for the consequences of this behaviour on the local community and environment.However,over the last decades,corporate scandals challenged that corporate model’s validity and paved the way for a sustainable corporate model.The latter emphasises a triple bottom line approach that incorporates social,economic,and environmental objectives.By implementing a sustainable corporate model,companies achieve both economic and social goals in a balanced approach.This research investigates the B Corporation(B Corp)certification system,which helps companies implement a sustainable corporate model voluntarily.B Corp certification is a badge signal that companies’business model adheres to ethical standards and meets socially conscious stakeholders’expectations.Our research aims to provide a deep contextual understanding of the determinants and implications of the B Corp certification’s adoption.We adopt a semantic approach to review and systematise management and accounting literature on Certified B Corporations(B Corps)through institutional theory’s lenses,which help us explain why firms decide voluntarily to become B Corps.

The invasive potential of a hybrid species: insights from soil chemical properties and soil microbial communities

Aims Natural hybridization between invasive and native species,as a form of adaptive evolution,threatens biodiversity worldwide.However,the potential invasive mechanisms of hybrids remain essentially unexplored,especially insights from soil chemical properties and soil microbial communities.Methods In a field experiment,soil microbial community,potassium-solubilizing bacteria,phosphorus-solubilizing bacteria,enzyme activities,and light-saturated photosynthetic rate were measured in invasive Sphagneticola trilobata and its hybrid with native Sphagneticola calendulacea in 2 years.Important Findings In general,soil dissolved organic carbon and the biomass of phosphorus-solubilizing bacteria were significantly higher under the hybrid treatment than S.trilobata and S.calendulacea.However,there were no significant differences in acid phosphatase,total PLFAs,bacterial PLFAs,fungi PLFAs,cellulase,and urase in these treatments.The hybrids had significantly higher light-saturated photosynthetic rate,photosynthetic nitrogen-,phosphorus-,potassium-use efficiencies than the invasive S.trilobata,but no significant difference with S.calendulacea.The total biomass and root biomass of hybrids were higher than S.calendulacea.Our results indicate that the hybrids species have a higher invasive potential than S.calendulacea,which may aggravate the local extinction of S.calendulacea in the future.

Research on the Renewal Strategy of Social Space for the Elderly in Colleges and Universities from the Perspective of Multi Generations:Take a University in the North as an Example

Under the background of population aging,while the living environment of the elderly is improved,it is necessary to pay attention to their spiritual needs and build an elderly-friendly and livable social environment.In this paper,through field investigation and research on social behavior and space,the social behavior and needs of the elderly in a university in the north were analyzed,and based on the social characteristics and psychological needs of the elderly and students in the university,the construction of a dynamic space with multi-generational shared space as the core was proposed to develop a social platform that integrates virtual and reality,so as to provide reference for the updating of social space in college communities in the future.

Genetic variation in foundation species governs the dynamics of trophic interactions

Various studies have demonstrated that the foundation species genetic diversity can have direct effects that extend beyond the individual or population level, affecting the dependent communities. Additionally, these effects may be indirectly extended to higher trophic levels throughout the entire community. Quercus castanea is an oak species with characteristics of foundation species beyond pre- senting a wide geographical distribution and being a dominant element of Mexican temperate forests. In this study, we analyzed the influence of population （He） and individual （HL） genetic diversity of Q. castanea on its canopy endophagous insect community and associated parasitoids. Specifically, we studied the composition, richness （S） and density of leaf-mining moths （Lepidoptera： Tischeridae, Citheraniidae）, gall-forming wasps （Hymenoptera： Cynipidae）, and canopy parasitoids of Q. castanea. We sampled 120 trees belonging to six populations （20/site） through the previously recognized gradi- ent of genetic diversity. In total, 22 endophagous insect species belonging to three orders （Hymenoptera, Lepidoptera, and Diptera） and 20 parasitoid species belonging to 13 families were identified. In general, we observed that the individual genetic diversity of the host plant （HL） has a significant positive effect on the S and density of the canopy endophagous insect communities. In contrast, He has a significant negative effect on the S of endophagous insects. Additionally, indirect effects of HL were observed, affecting the S and density of parasitoid insects. Our results suggest that genetic variation in foundation species can be one of the most important factors governing the dynamics of tritrophic interactions that involve oaks, herbivores, and parasitoids.
