Effects of Community Community Communication Technology(ICT) Usage on Community Satisfaction: Case Study in Nanjing, China

Future or smart community, which mainly refers to the development of community information and communication technology(ICT) platforms or devices, has received considerable attention from urban governments and scholars. However, only a few studies have been conducted to test the actual effects of using these community ICT platforms or devices on the community satisfaction of residents. Therefore, the present study conducts a survey in 40 communities in Nanjing, China and uses a mixed linear regression model to determine the relationship between community ICT usage and community satisfaction. Results indicate that residents with high-level community ICT usage are more satisfied with their community than those with low-level community ICT usage. Moreover, evident differences are observed regarding the influence of new commodity, old commodity and affordable housing communities in Nanjing. These findings are meaningful for the construction and development of future communities.

Technology and Community in a Rural Culture: The Amish

The Amish are a marginal outgroup in the United States who have remained far from the center of the dominant society in their nearly 400 year history.This is in part due to a judicious acceptance and adoption of newer technologies,as these are not viewed as vales free.This highly religious community is promoted as a tourist attraction by various states where their communities flourish.Their culture seems quaint or antiquated,though this is partly due to a preference for older methods of labor and production that have stood the test of time and serve to maintain integrity of the culture.The Amish have been persecuted in past for choosing to be a non-violent culture,which has also prohibited their exposure to various technologies.Their history in America runs counter to the culture and experiences of the dominant social culture,as well as many minority cultures.Their endurance and success run counter to much of the development of social welfare milestones and policy in America.Yet,the Amish represent marginal and oppressed people in immigrant history.Many who promote their culture continue to exploit them based upon the misunderstandings of the larger society.Some who write about them perpetuate these misconceptions.This paper seeks to examine critically via the selection of available historical evidence,and through the historical observations of earlier writers raised in Amish tradition,how the Amish view themselves and concerning technology within their culture.

Improving wellbeing of community-dwelling people with mild cognitive impairment: the SENIOR (SystEm of Nudge theory based ICT applications for OldeR citizens) project

Population aging with longer life expectancy represents one of the most relevant challenges of the next future,also because of a significant proportion of older adult people may present with dementia.Motivating senior citizens with mild cognitive impairment to maintain their independence and functional abilities,improve health status and quality of life as well as social interactions,constitutes the main target of preventive medicine.According to a nudge theoretical approach,the SENIOR(SystEm of Nudge theory based ICT applications for OldeR citizens)project–developed thanks to the collaboration among Catholic University of the Sacred Heart,Bicocca University and IRCCS Auxiologico Institute in Milan(Italy)–has been designed to adopt an advanced information and communication technology coaching system able to collect and integrate physiological,psychological and behavioral data,with the final aim of interacting with community-dwelling elderly people suffering from mild cognitive impairment and of providing them personalized feedback on lifestyle management.The SENIOR project proposes to use a smart-watch app for alerting family doctors,sharing information with family members in specific cases and monitoring patients at higher risk in hospital Units,in order to ameliorate health of senior citizens with mild cognitive impairment.

VisQAC: Visual Analytics for Online Q&A Communities

Online question and answer(Q&A)communities,which allow users to exchange knowledge by asking and answering questions,have become increasingly popular.As a result of user active participation,these communities store overwhelming volumes of information.However,existing related methods are unable to meet community operators’needs for analyzing multi-dimensional Q&A sequences and understanding user behavior.In this paper,collaborating with domain experts in online community,we present a system,VisQAC,which explores the patterns of Q&A sequence and user behavior.In the system,a novel visual design is proposed,which is combined with flexible mapping measures for analyzing critical characteristics of sequence data.Moreover,a timeline visualization method is designed to visualize data with categorical attributes and its correlation can be displayed flexibly by choosing time mode and time granularity.The usefulness and effectiveness of the system are demonstrated with several case studies of VisQAC with community operators based on the Zhihu dataset.Our evaluation shows that VisQAC is beneficial to the understanding of Q&A sequence and associated user behavior.

Application of biofl oc technology in recirculation A rtemia culture system

Biofl oc technology(BFT)improves water quality,and productivity of the farmed species through converting ammonium nitrogen to microbial protein,stabilizing microbial community,and reducing the production cost.In this study,a small-scale biofl oc development unit was designed in combination of recirculation system(RAS)for Artemia culture.Artemia growth,water quality,and microbial composition of biofl ocs in RAS were studied in comparison with in-situ batch culture(Glu).Glucose was added in RAS and Glu at C/N ratio of 10.The cultures without glucose addition,but with 50%daily water renewal(WRe)and without water renewal(NWRe)were considered as the controls.Arte mia were cultured at 25℃ and salinity 30 for 24 days and fed formulated feed.The results showed that compared to the controls,Glu signifi cantly improved the Artemia biomass,increased the biofl oc volume,and reduced the content of total ammonia nitrogen(TAN),nitrite nitrogen(NO_(2)-N)and nitrate nitrogen(NO_(3)-N)in water column(P<0.05).In addition,RAS had similar results with Glu.High throughput sequencing analysis on biofl oc microbial composition demonstrated that glucose supplement shaped the microbial community structure,and increased proportion of potential probiotic bacteria and suppressed pathogenic bacteria growth.Furthermore,we analyzed the relationship between the microbial composition of biofl oc and environmental factors.Canonical correspondence analysis(CCA)indicated that inorganic nitrogen in culture water had great impact on biofl oc microbial composition in NWRe and WRe,whilst the dissolved organic carbon(DOC)modifi ed the microbial community in Glu and RAS.This study shows the advantages of BFT in Artemia culture and provides practical information for applying BFT-RAS in indoor Artemia culture.

Effect of a compound starter cultures inoculation on bacterial profile and biogenic amine accumulation in Chinese Sichuan sausages

Effects of a starter culture composed of Lactobacillus sakei,Pediococcus pentosaceus,Staphylococcus xylosus and S.carnosus at the ratios(m/m)of 1:1:1:1 on bacterial profile and biogenic amine accumulation in Chinese Sichuan sausages were demonstrated.In starter culture-inoculated sausages,Lactobacillus spp.,Pediococcus spp.and Staphylococcus spp.were predominant bacterial genus and their relative abundances ranged from 70.14%to 25.98%,57.66%to 14.08%,and 15.71%to 13.40%during fermentation,respectively.Accordingly,Lactobacillus spp.and Weissella spp.were predominant bacterial genus and their relative abundances ranged from 63.14%to 24.70%and 49.40%to 11.96%during spontaneous fermentation,respectively.Furthermore,the abundances of undesirable microorganisms such as Yersinia spp.,Enterobacter spp.,Acietobacter spp.and Psychrobacter spp.were lower than that of the control.The levels of histamine,putrescine,tyramine and cadaverine in Chinese Sichuan sausages with starter cultures inoculation were significantly lower(P<0.05)than that of the control,and were decreased by 83.09%,69.38%,51.87%and 57.20%,respectively,at the end of the ripening.These results revealed that the starter cultures inoculation was a better alternative for microbial quality improvement and biogenic amine reduction of Chinese Sichuan sausages with good sensory attributes.

Preliminary Explanation on "Natural Activation Theory" Based on "Fenlong"

Based on action mechanism of "Fenlong technology" with the maximum activation potential of global natural resources,"natural resources activation theory"("activation theory") is proposed firstly.Its connotation contains two parts.One is directly activating some natural resources in land,such as unutilized plough bottom of existing cultivated land and soil resources below it,saline-alkali land,degraded grassland,ecological reconstruction of desertification land,inter-row of fruit trees,lawn of sponge city,etc.The other is indirectly activating some natural resources in ground space,such as natural precipitation,solar energy,oxygen,terrestrial eco-environment,soil resources,river waters and even climate change factors.It could release and generate huge physical endogenous force and cyclic force,and increase food source and available water resources,which is favorable for human survival,nature's own ecological balance,harmonious coexistence and balance between man and nature,without harming nature itself.Moreover,its supporting theoretical system is explained from five aspects.It is pointed that the "activation theory" is deep derivation of "Fenlong technology" and "Fenlong science".By sufficiently playing the potential of natural resources,it could reach human-dominated comprehensive balance and coordinated development of air,sunshine,water,soil,nutrient,microorganism,plant,livestock and poultry,marine organism in the nature.The "activation theory" is concrete embodiment of respecting,changing and using the nature,and new channel of realizing sublimation of "life community of human and nature" and benefiting mankind.

Co-Creation in the Game Industry:A Case Study in a Brazilian Developer

The objective of this work is to understand how the process of co-creation occurs within the creative industry of video games. For this, concepts of the creative industry, co-creation, information and communication technologies (ICTs) and innovation were studied. Since this is an exploratory and qualitative research, a single case study was chosen as a method. The analysis was done in a Brazilian company that develops games for mobile devices. The results show that the consumer (gamer) participates in value creation in the company’s products, mainly in the initial production stages. In the later phases, after the launch and other steps of the life cycle, although there is a relationship with the users, the joint creation of value is little explored by the organization. Also, it was verified that the co-creation process is supported by different information and communication tools, which provide agility to the process.

The impact of social capital on children's (6–12) use of ICT in urban communities: A field survey from Zhengzhou City, Henan Province

Purpose： This paper focuses on the impact of social capital on urban children＇s use behavior of information communication technology （ICT）.Design/methodology/approach： Using the field survey and in-depth interviews, we interviewed 40 children aged 6 to 12 and their parents from a staff residential quarter of the Zhengzhou University--＂Shengheyuan＂ community （SHY）, and a commercial residential quarter--＂Wanfenghuicheng＂ community （WFHC） in the high-tech zone of Zhengzhou City, Henan Province. We used the social capital theory to analyze the interviewees＇ record.Findings： In urban communities, social capital is the most important factor for children （aged 6 to 12） in their ICT use. Our findings indicate that children in families with higher levels of social capital, such as internal resources, family income, parent educational backgrounds and parents＇ social network, have more-highly developed ICT skills. Personal motivation and obstacles, such as lack of access to computers on a regular basis, also have an impact on children＇s ICT use. External social capital, including schools, libraries, and public service institutes, have little impact on children＇s ICT use, if not combined with internal social capital factors.Research limitations： Our research samples were collected from two communities within the same city, which may influence the generalization of this research result.Originality/value： To explore the social capital＇s influence on children＇s ICT use, we used field observation for ICT use of children aged 6 to 12 in urban communities in China, and studied the children＇s ICT behavior from the perspective of internal and external social capital.

THE SCIENCE AND TECHNOLOGY BACKYARD AS A LOCAL LEVEL INNOVATION INTERMEDIARY IN RURAL CHINA

Agricultural innovation can be described as a coevolutionary process of technological innovation,symbolic change,and social or institutional innovation,which relies on the interactions and collaboration between multiple stakeholders.This view emphasizes the significance of innovation intermediaries in supporting the coevolution process of innovation.Many studies have provided evidence on how innovation intermediaries play roles in supporting the coevolution innovation process at a broader innovation system level.However,little emphasis has been given to the role of innovation intermediaries in supporting the coevolution process of innovation at the community level in rural China.To address this research gap,this paper offers a case study of a novel type of innovation support intervention designed to promote technical change at the community level,the Science and Technology Backyard(STB).The paper focuses on the efforts of a specific STB in Wangzhuang village to promote innovation in tillage methods in wheat production.The aims was to examine the role of this newly emerging innovation support intervention in supporting the coevolution process of innovation at the community level,and compare the outcome of the coevolution process in the village with an STB to that in villages without an STB.Innovation journey analysis is applied to understand the evolved intermediation roles in the innovation process,and multivariate regression analysis is employed to assess the outcome of the coevolution process in villages with and without an STB.The findings suggest that the roles of STBs have evolved from knowledge brokers to systemic innovation intermediaries that facilitate the coevolution process of innovation inside an STB village.It has led to a higher adoption rate of improved technology,a better enabling environment for learning,and more effective institutional support in STB villages than in non-STB villages.However,the effect of support provided by a single STB on the coevolution process outside the community was limited.This finding points to a need for collaboration mechanisms and for connecting single STBs to support the coevolution process of innovation at a larger scale.

Comparing salinities of 0, 10 and 20 in biofloc genetically improved farmed tilapia (Oreochromis niloticus) production systems

A 150 days(150-d)experiment was carried out to investigate the production efficiency,inorganic nitrogen syndrome and bacteria community of indoor biofloc technology(BFT)systems used to rear genetically improved farmed tilapia(Oreochromis niloticus)under 0(S-0),10(S-10),and 20 salinities(S20).The start-up period for BFT was 50,60 and 80 d for S-0,S-10 and S-20 groups,respectively.At steady state,the total ammonium nitrogen(NH4þ-N)and nitrite nitrogen(NO2-N)were lower than 3.0 mg/L and 0.34 mg/L,respectively and no nitrate-nitrogen(NO3-N)accumulation was observed.The fish survival rate was above 95%for all the groups.The final fish biomass of the S-10 group(35.83±1.08 kg/m^(3))was not significantly different from the S-0(34.79±1.33 kg/m^(3))group but was significantly higher than S-20(32.6±1.04 kg/m3).The feed conversion ratio for the tilapia in S-20 was 1.46,which was higher than the ratio in S-0(1.40)and S-10(1.39)tilapia.There was no significant difference in the crude protein content of the back muscle from tilapia of the three experimental groups.No significant difference in blood parameters,except for aspartate aminotransferase and alkaline phosphatase was observed between the three groups.Evaluation of microorganisms in the three BFT systems revealed that Proteobacteria,Bacteroidetes,and Fusobacteria were the top three at the phylum level in all groups.However,a significant difference was observed at the genus level in the bacteria of the three BFTs at different salinity(P<0.05).©2017 Published by Elsevier B.V.on behalf of Shanghai Ocean University.This is an open access article。

Monitoring stratification of anode biofilms in bioelectrochemical laminar flow reactors using flow cytometry

A laminar flow bioelectrochemical systems(BES)was designed and benchmarked using microbial anodes dominated with Geobacter spp.The reactor architecture was based on modeled flow fields,the resulting structure was 3D printed and used for BES manufacturing.Stratification of the substrate availability within the reactor channels led to heterogeneous biomass distribution,with the maximum biomass found mainly in the initial/middle channels.The anode performance was assessed for different hydraulic retention times while coulombic efficiencies of up to 100%(including also hydrogen recycling from the cathode)and current densities of up to 75 μA cm^(-2) at an anode surface to volume ratio of 1770 cm^(2) L^(-1) after 35 days were achieved.This low current density can be clearly attributed to the heterogeneous distributions of biomass and the stratification of the microbial community structure.Further,it was shown that time and space resolved analysis of the reactor microbiomes per channel is feasible using flow cytometry.

Preparation and characterization of a novel microorganism embedding material for simultaneous nitrification and denitrification

A novel microorganism embedding material was prepared to enhance the biological nitrogen removal through simultaneous nitrification and denitrification. Polyvinyl alcohol （PVA）, sodium alginate （SA） and cyclodextrin （CD） were used to compose gel bead with embedded activated sludge. The effects of temperature, CD addition and concentrations of PYA and SA on nitrogen removal were evaluated. Results show that the gel bead with CD addition at 30℃contributed to the highest nitrogen removal efficiency and nitrogen removal rate of 85.4% and 2.08 mg·（L·h）^-1, respectively. Meanwhile, negligible NO3^- and NO2^- were observed, proving the occurrence of simultaneous nitrification and denitrification. The High-Throughput Sequencing confirms that the microbial community mainly contained Comamonadaceae in the proportion of 61.3%. Overall, CD increased gel bead＇s porosity and resulted in the high specific endogenous respiration rate and high nitrogen removal efficiency, which is a favorable additional agent to the traditional embedding material.
