Social media collected over time using keywords, hashtags and accounts associated with a particular geographic community might reflect that community’s main events, topics of discussion, and social interactions. We are interested in evidence for the support of community involvement that the aggregated Web pages and social media might help to create. We collected and analyzed Twitter data related to a geographic area over a two-year period to identify and characterize relevant topics and social interactions, and to evaluate the support for community involvement that such Twitter use might indicate. This kind of data collection has built-in biases, of course, just as local print media or online newsgroups do. We analyzed our data using the open source tool NodeXL to identify topics and their changes over time, and to create social graphs based on retweets and @ mentions that suggest interactions around topics. Our findings show: 1) distinct topics; 2) large and small clusters of social interactions around a variety of topics; 3) patterns suggesting what are called ‘community clusters’ and ‘tight crowd’ types of conversations; and, 4) evidence that Twitter supports local community involvement among users. Modeling topics over time and displaying visualizations of social interactions around different topics in a community can offer insights into the important events and issues during a given period. Such visualizations also reveal hidden (or obscure) topics due to a smaller number of participants — whether government representatives, voluntary associations, or citizens. There is clear evidence that Twitter supports social interaction and informal discussion or exchange around local topics among users, thereby facilitating community involvement.

Identifying and detecting web spam is an ongoing battle between spam-researchers and spammers which has been going on since search engines allowed searching of web pages to the modern sharing of web links via social networks. A common challenge faced by spam-researchers is the fact that new techniques depend on requiring a corpus of legitimate and spam web pages. Although large corpora of legitimate web pages are available to researchers, the same cannot be said about web spam or spam web pages. In this paper, we introduce the Webb Spam Corpus 2011 — a corpus of approximately 330,000 spam web pages — which we make available to researchers in the fight against spam. By having a standard corpus available, researchers can collaborate better on developing and reporting results of spam filtering techniques. The corpus contains web pages crawled from links found in over 6.3 million spam emails. We analyze multiple aspects of this corpus including redirection, HTTP headers, web page content, and classification evaluation. We also provide insights into changes in web spam since the last Webb Spam Corpus was released in 2006. These insights include: (1) spammers manipulate social media in spreading spam; (2) HTTP headers and content also change over time; (3) spammers have evolved and adopted new techniques to avoid the detection based on HTTP header information.

The COVID-19 global pandemic brought forth wide-ranging, unanticipated changes in human interaction, as communities rushed to slow the spread of the coronavirus. In response, local geographic community members created grassroots care-mongering groups on social media to facilitate acts of kindness, otherwise known as care-mongering. In this paper, we are interested in understanding the types of care-mongering that take place and how such care-mongering might contribute to community collective efficacy (CCE) and community resilience during a long-haul global pandemic. We conducted a content analysis of a care-mongering group on Facebook to understand how local community members innovated and developed care-mongering practices online. We observed three facets of care-mongering: showing appreciation for helpers, coming up with ways of supporting one another's needs, and continuing social interactions online and present design recommendations for further augmenting care-mongering practices for local disaster relief in online groups.

Chinese Social Media

In this paper we analyze the concepts of fenxiang and gongxiang—the Mandarin words for ‘sharing’—in the context of Chinese social media. Drawing on earlier work on ‘sharing’, and based on analyses of four corpuses and changes over time to the homepages of 32 Chinese social network sites (accessed through the Wayback Machine), we find that the concepts of fenxiang and gongxiang offer a heuristic for understanding Chinese social media, while also pointing to an important facet of the discursive construction of Chinese social media. Although seeming to refer to the same activities as ‘sharing’, analysis of the language of fenxiang and gongxiang in Chinese social media reveals the entanglement of a new individualistic self with a self that remains socially embedded in pre-existing relationships; it shows how micro-level harmony (fenxiang) and macro-level harmony (gongxiang) cohere with each other; while also reflecting the interplay among social media platforms, users, and the state.

PurposeInternal social media (ISM) make it possible for all employees to participate in knowledge sharing and decision-making and to voice their opinions. However, several studies have found that organizations are far from unlocking the full potential of ISM. This paper seeks to explore and explain this gap further by adopting a sensemaking lens to managers' understanding of a social intranet in a public sector organization.Design/methodology/approachA longitudinal case study of the process of introducing ISM was conducted in a Danish municipality. Before, during and after the launch of the intranet, interviews with department heads and communication managers in the six different municipal departments were carried out to explore how they made sense of the purpose of ISM.FindingsFindings indicate that during the process of introducing and implementing ISM, department heads' and managers' narratives about the purpose of the intranet changed from being a matter of involving, engaging and hearing the voices of the employees to being an effective administrative tool and a channel for management to reach all employees.Originality/valueRather than the traditional focus on whether ISM fail or succeed, the paper offers new understandings of how managers' sensemaking of ISM changes over time, leading to changes in the actual usage of and communication on ISM.

Existences of public spaces in cities are essentials for social interactions to take place, fostering the creation of sustainable, safe and livable cities. Although public spaces are often designed for certain activities, existence of unplanned spaces seemed interwoven in the cityscape, some in the form of leftover spaces, including under the flyovers and bridges, which offers an abundance of opportunities. This paper attempts to review activities under flyovers initiated by its local community in Kuala Lumpur and aims to contribute in further identifying the leftover spaces, and to the possible activities to be considered in developing these spaces to benefit surrounding communities.

This chapter examines the affordances of information and communication technologies (ICTs) and the different intergenerational practices of oversharing online. Using the concepts of ‘aesthetics of appearance’ (representation that endures over time and space) and ‘aesthetics of disappearance’ (constant presentism), it asks what prompts oversharing, what oversharing reveals about our life stages and the state of being human in an age of over-acceleration dominated by ICTs, and how oversharing affects our embodied phenomenology. The chapter first provides an overview of ideas about acceleration and the resulting aesthetics of disappearance, as proposed by philosopher and urbanist Paul Virilio, before discussing how the phenomenon of oversharing is mediated by social media platforms such as Facebook and Snapchat. It then considers whether posting selfies on a Facebook page constitutes oversharing and whether oversharing (real-time presence) achieves what Virilio calls an aesthetics of disappearance. Finally, it explores how oversharing impacts social interactions and intergenerational relationships.

Abstract Modeling social interaction can be based on graphs. However most models lack the flexibility of including larger changes over time. The Barabási-Albert-model is a generative model which already offers mechanisms for adding nodes. We will extent this by presenting four methods for merging and five for dividing graphs based on the Barabási- Albert-model. Our algorithms were motivated by different real world scenarios and focus on preserving graph properties derived from these scenarios. With little alterations in the parameter estimation those algorithms can be used for other graph models as well. All algorithms were tested in multiple experiments using graphs based on the Barabási- Albert-model, an extended version of the Barabási-Albert-model by Holme and Kim, the Watts-Strogatz-model and the Erdős-Rényi-model. Furthermore we concluded that our algorithms are able to preserve different properties of graphs independently from the used model. To support the choice of algorithm, we created a guideline which highlights advantages and disadvantages of discussed methods and their possible use-cases.

This paper is for the 2017 Annual Meeting, Society for American Archaeology.Although initially developed to understand contemporary urban systems, the method and theory of settlement scaling are particularly appropriate for archaeological data. The scaling framework can be seen as an outgrowth of existing archaeological research on demography and settlement patterns. Although developed independently, the "social reactor" model that explains observed patterning is, in fact, well grounded in anthropological and archaeological theory. The key process that drives change is “energized crowding,” or the social interactions among individuals within the built environment. The scaling framework is general enough to apply to settlements in all types of human societies; it does not require the institutions or behaviors of the contemporary capitalist economy. This is a thoroughly empirical line of research that generates propositions that can be rigorously tested against archaeological data. Our positive findings to date contribute to a richer and broader fundamental understanding of human settlements, their generative character, and their changes over time.

Abstract. Summary: Background: We aimed at estimating the agreement between the Medicap® (photo-optical) and Radiometer® (electro-chemical) sensors during exercise transcutaneous oxygen pressure (tcpO2) tests. Our hypothesis was that although absolute starting values (tcpO2rest: mean over 2 minutes) might be different, tcpO2-changes over time and the minimal value of the decrease from rest of oxygen pressure (DROPmin) results at exercise shall be concordant between the two systems. Patients and methods: Forty seven patients with arterial claudication (65 + / - 7 years) performed a treadmill test with 5 probes each of the electro-chemical and photo-optical devices simultaneously, one of each system on the chest, on each buttock and on each calf. Results: Seventeen Medicap® probes disconnected during the tests. tcpO2rest and DROPmin values were higher with Medicap® than with Radiometer®, by 13.7 + / - 17.1 mm Hg and 3.4 + / - 11.7 mm Hg, respectively. Despite the differences in absolute starting values, changes over time were similar between the two systems. The concordance between the two systems was approximately 70 % for classification of test results from DROPmin. Conclusions: Photo-optical sensors are promising alternatives to electro-chemical sensors for exercise oximetry, provided that miniaturisation and weight reduction of the new sensors are possible.
