A functional test platform for the Community Land Model

The realistic representation of key biogeophysical and biogeochemical functions is the fundamental of process-based ecosystem models. A functional test platform is designed to create direct linkages between site measurements and the process-based ecosystem model within the Community Earth System Models (CESM). The platform consists of three major parts: 1) interactive user interfaces, 2) functional test models and 3) observational datasets. It provides much needed integration interfaces for both field experimentalists and ecosystem modelers to improve the model's representation of ecosystem processes within the CESM framework without large software overhead.     

国际制度与国家认同互动关系解析——以欧美安全共同体的建构为例

在国际社会中认同与制度化构成一个互动的关系。从认同的角度来看，正向的国家间认同为制度化的发展打下良好基础；从制度的角度来看，国际制度为国家认同的塑造提供平台，高级制度化往往伴随着一个国家内化规范及认同建构的过程。二战后的欧美安全关系的发展就是一个认同与制度化良好互动的典型例证。双方在良好认同的基础上开始制度化进程，而在国际制度基础上的国家间交往，则进一步加深二者对彼此的认知程度，推动欧美关系朝积极的方向发展，最终建立一个稳定有效的欧美安全共同体。     

Social media use,community participation and psychological well-being among individuals with serious mental illnesses

BackgroundLittle research exists on social media (e.g., Facebook, Twitter, etc.) use among individuals with serious mental illnesses (SMI). One particular question of interest is the extent to which online social media use is associated with these individuals' community participation, civic engagement and psychosocial outcomes.MethodsTwo-hundred and thirty-two individuals with SMI receiving services at 18 mental health organizations throughout the continental U.S. completed questionnaires on their community participation, civic engagement, quality of life, loneliness, and psychiatric symptoms. They were also asked which social media sites they used; the duration, frequency and importance of, and reasons for, social media use; and the number of contacts they had on social media.ResultsApproximately a third of the sample reported having at least one social media account. Greater frequency, intensity and longevity of social media were associated with higher levels of community participation, and greater intensity of social media use was positively associated with civic engagement. For instance, those who used social media at least 30 min a day had 16.4 more days of participation and voting rates that were higher by 17.4%. Social media use was not found to be significantly associated with loneliness, psychiatric symptoms or quality of life.Discussion and implicationsGreater social media use appears to be associated with greater community engagement without negative repercussions on loneliness, symptoms, or quality of life. Interventions that support social media use among individuals with SMI could have important community integration benefits.     

Detecting discussion communities on vaccination in twitter

Vaccines have contributed to dramatically decrease mortality from infectious diseases in the 20th century. However, several social discussion groups related to vaccines have emerged, influencing the opinion of the population about vaccination for the past 20 years. These communities discussing on vaccines have taken advantage of social media to effectively disseminate their theories. Nowadays, recent outbreaks of preventable diseases such as measles, polio, or influenza, have shown the effect of a decrease in vaccination rates. Social Networks are one of the most important sources of Big Data. Specifically, Twitter generates over 400 million tweets every day. Data mining provides the necessary algorithms and techniques to analyse massive data and to discover new knowledge. This work proposes the use of these techniques to detect and track discussion communities on vaccination arising from Social Networks. Firstly, a preliminary analysis using data from Twitter and official vaccination coverage rates is performed, showing how vaccine opinions of Twitter users can influence over vaccination decision-making. Then, algorithms for community detection are applied to discover user groups opining about vaccines. The experimental results show that these techniques can be used to discover social discussion communities providing useful information to improve immunization strategies. Public Healthcare Organizations may try to use the detection and tracking of these social communities to avoid or mitigate new outbreaks of eradicated diseases.     

Automatic network clustering via density-constrained optimization with grouping operator

Automatic network clustering is an important technique for mining the meaningful communities (or clusters) of a network. Communities in a network are clusters of nodes where the intra-cluster connection density is high and the inter-cluster connection density is low. The most popular scheme of automatic network clustering aims at maximizing a criterion function known as modularity in partitioning all the nodes into clusters. But it is found that the modularity suffers from the resolution limit problem, which remains an open challenge. In this paper, the automatic network clustering is formulated as a constrained optimization problem: maximizing a criterion function with a density constraint. With this scheme, the established algorithm can be free from the resolution limit problem. Furthermore, it is found that the density constraint can improve the detection accuracy of the modularity optimization. The efficiency of the proposed scheme is verified by comparative experiments on large scale benchmark networks.     

Reprint of “Emergent public space: Sustaining Chicano culture in North Denver”

Vacant land located in deteriorating neighborhoods collects physical detritus and social malaise; overt signifiers of urban blight, these spaces often become gathering places for garbage instead of people, illicit activity instead of civility. This essay deconstructs what happens when community activists appropriate, develop, and continually manage vacant land in manners that align with and express their community’s culture. Moreover, it deconstructs the metamorphosis of vacant land into public space. Part of a larger research project exploring the roles public space plays in neighborhood change, this ethnography centers in Sunnyside, a gentrifying neighborhood in Denver, Colorado. Combining ethnographic and archival methods, I explore how the physical, regulatory, and cultural facets interrelate to form something rather remarkable—public space on private property. The “Troy” Chavez Memorial Peace Garden is at once a community garden, a pedagogical space, and a memorial to the 108 youths who died in Denver’s 1993 “summer of violence”. Twenty years later it is still cherished as a garden and a memorial, as a living artifact of Aztec culture, and as a publicly accessible space that contributes to the cooperation between neighborhood old-timers and newcomers. Turning scholarly discourse of the privatization of public space on its head, I unpack the processes contributing to the publicizing private space.

Media as Educator,Media as Disruptor: Conceptualizing the Role of Social Context in Media Effects

We document how social contexts serve to refract media effects. We theorized the relationship between media use and individual‐level knowledge (and attitude) would be stronger when community‐level knowledge (and attitude) was low than when it was high. Data come from a national survey (N = 12,608 women and 1,237 men) conducted in Nepal. Knowledge and stigma toward people living with HIV were the 2 dependent variables. Hypotheses were tested 12 times: across the use of 3 media (newspaper, radio, television) × 2 study outcomes (knowledge and attitudes) × 2 genders. Predicted interactions were supported in 9 of the 12 tests. Findings point to the need to take into account the role of community factors in theorizing about media effects.     

Global Village Media: Coming Together in the Early 1970s at Whiz Bang Quick City

Felicity D Scott , Associate Professor of Architecture at Columbia University Graduate School of Architecture, Planning and Preservation (GSAPP), describes here the instant city events of the early 1970s. These foreshadowed current global village media practices in what now seems a quaintly material manner: communication between sites involved the physical mailing of videotapes and ‘wire photos’ through the postal service. The sites themselves – in the US and elsewhere – were transformed into ‘instant cities’ through the erection of physical geodesic domes, teepees and inflatables in seas of mud. The true antecedents of today's instant networking, these pioneers embraced the newest technology available at the time and the most innovative forms of temporary architecture.
