Online discussion communities play an important role in the development of relationships and the transfer of knowledge within and across organizations. Their underlying technologies enhance these processes by providing infrastructures through which group-based communication can occur. Community administrators often make decisions about technologies with the goal of enhancing the user experience...

Coexistence of predators that share the same prey is common. This is still the case in size-structured predator communities where predators consume prey species of different sizes (interspecific prey responses) or consume different size classes of the same species of prey (intraspecific prey responses). A mechanism has recently been proposed to explain coexistence between predators that differ ...

Local newspapers are an important source of health news, especially in small communities. We describe the amount and type of cancer information in Ontario daily newspapers dichotomized by circulation size (> 400,000 or < 40,000) and community size (> 250,000 or < 25,000 people) for 1991. All cancer articles (n = 1027) in five newspapers with large circulations, serving large communities, and fi...

Expenditures, staffing, and outcomes were examined for 116 adults with severe or profound mental retardation who moved from state institutions in Minnesota to various community living settings and a comparison group of 71 persons who remained institutionalized. Outcome variables included community access, social activities, community inclusion, family relationships, and choice. Comparison of pa...

the frequency and impacts of floods have increased in iran in the past few decades. as flood events are in most instances associated with human activities, mitigating their impacts requires non-structural and community-based initiative alongside structural measures. in this connection, the concept of community resilience has been advanced in recent times, which attaches importance to interactio...

Aim Body size often plays a significant role in community assembly through its impacts on the life history and ecological attributes of species. Insight into the importance of size in structuring communities can be gained by examining the distribution of sizes of individuals [i.e. the individual size distribution (ISD) or size spectrum] in a community. ISDs have been studied extensively in aqua...

Convergence at the community level occurs when whole groups of organisms become more similar than their ancestors in a similar environment. I suggest a method for indirectly assessing community convergence, and apply it to several characteristics of finch communities in different habitats worldwide. The method is based on the analysis of variance, and has several advantages over other indirect ...

BACKGROUND Community structure is one of the key properties of complex networks and plays a crucial role in their topology and function. While an impressive amount of work has been done on the issue of community detection, very little attention has been so far devoted to the investigation of communities in real networks. METHODOLOGY/PRINCIPAL FINDINGS We present a systematic empirical analysi...
