Gamification Features 4 Fitcity
The document discusses various gamification features that could be used for the FitCity project, including badges, points, levels, progress bars, tutorials, and leaderboards. It provides examples of each feature and references related research. While gamification aims to increase engagement, the document notes that all gamification features provide extrinsic rather than intrinsic rewards, and warns of both benefits and risks to different features.

Social fitness (fitcity project)
This document discusses using social and gamification elements to encourage fitness and healthy behaviors. It explores how tracking activity and sharing accomplishments on social media can motivate people. Gamifying fitness by awarding badges or turning exercise into games is also discussed as a way to make fitness more engaging. The document also references research showing that peer pressure from friends and seeing how one's own progress compares to others can promote greater physical activity levels.

Collective Memory building in Wikipedia: the case of North African uprisings
Paper presented at Wikisym 2011, 7th International Symposium on Wikis and Open Collaboration
Read the paper at http://www.gnuband.org/papers/collective_memory_building_in_wikipedia_the_case_of_north_african_uprisings/
Authors: Michela Ferron, Paolo Massa
Abstract:
Since December 2010, a series of protests and uprisings have shocked North African countries such as Tunisia, Egypt, Libya, Syria, Yemen and more. In this paper, focusing mainly on the Egyptian revolution, we provide evidence of the intense edit activity occurred during these uprisings on the related Wikipedia
pages. Thousands of people provided their contribution on the content pages and discussed improvements and disagreements on the associated talk pages as the traumatic events unfolded. We
propose to interpret this phenomenon as a process of collective memory building and argue how on Wikipedia this can be studied empirically and quantitatively in real time. We explore and suggest possible directions for future research on collective memory formation of traumatic and controversial events in Wikipedia.
Social networks of Wikipedia - Paolo Massa - Presentation at (2011). ACM Hype...
The paper is at http://www.gnuband.org/papers/social_networks_of_wikipedia/
Wikipedia, the free online encyclopedia anyone can edit, is a live social experiment: millions of individuals volunteer their knowledge and time to collective create it. It is hence interesting trying to understand how they do it. While most of the attention concentrated on article pages, a less known share of activities happen on user talk pages, Wikipedia pages where a message can be left for the specific user. This public conversations can be studied from a Social Network Analysis perspective in order to highlight the structure of the “talk” network. In this paper we focus on this preliminary extraction step by proposing different algorithms. We then empirically validate the differences in the networks they generate on the Venetian Wikipedia with the real network of conversations extracted manually by coding every message left on all user talk pages. The comparisons show that both the algorithms and the manual process contain inaccuracies that are intrinsic in the freedom and unpredictability of Wikipedia growth. Nevertheless, a precise description of the involved issues allows to make informed decisions and to base empirical findings on reproducible evidence. Our goal is to lay the foundation for a solid computational sociology of wikis. For this reason we release the scripts encoding our algorithms as open source and also some datasets extracted out of Wikipedia conversations, in order to let other researchers replicate and improve our initial effort.
Scripts (Python) has been released as open source and networks datasets (in GraphML format) too. See http://sonetlab.fbk.eu/data/social_networks_of_wikipedia/

Combining Ridesharing& Social Networks
Pooll is a ridesharing service that combines social networks to address issues of flexibility, trust, safety, and reliability. It allows travelers to announce trips that are matched with others' trips. When trips coincide, travelers are notified and can invite each other. Confirmed trips provide meeting details. Future versions include mobile apps and payment systems. Pooll innovates by using social networks to provide profile information to evaluate trustworthiness of other travelers and address the main problems preventing ridesharing adoption.
The Simplicity Cycle by Dan Ward
This document describes "The Simplicity Cycle", which plots complexity on the y-axis and goodness on the x-axis. It explores four regions: 1) The Region of the Simplistic, 2) The Region of the Complex, 3) The Region of the Complicated, and 4) The Region of the Simple. The key points are that increased complexity does not always lead to increased goodness, and that maximizing goodness requires both increasing and decreasing complexity through "genesis" and "synthesis". The cycle represents the ongoing process of achieving simplicity through understanding complexity.

Bowling Alone and Trust Decline in Social Network Sites
In this paper we analyze the community of a social network site, Advogato. The peculiar characteristics of Advogato is that users can explicitly express weighted trust relationships among themselves. We conduct a longitudinal analysis of the trust network over a time period of 4 years, exploring the community as it grew from a knit circle of 300 users to an society of almost 6500 individuals. We report the changes over time of standard indexes in social network analysis such as clustering and degrees of separation. We then focus on specific measures about trust such as reciprocity and changes over time of average trust. A decline in trust is observed as the community grows. Following what we believe to be the first empirical analysis of trust evolution over time in a real community, we conclude suggesting how the availability of data about human relationships in social network sites is opening up the possibility of monitoring changes in trust in real time. In order to foster this research line, we released the datasets and the code we used in our analysis.
Social Networking 4 your business
This document discusses how social networking can benefit businesses and provides strategies and examples for how companies can engage strategically on social media platforms like Facebook, Twitter, and blogs. It emphasizes listening to conversations, engaging with customers in a personal, transparent way, and monitoring social media to respond and spread your brand's message virally. Examples are given of Italian companies that have successfully used these tactics on social media.
OMG Girlz Don't Exist on teh Intarweb!!!!1
The document discusses evolutionary psychology perspectives on gender differences in video game preferences. It argues that hunter-gatherer lifestyles shaped male and female minds differently, with men specializing in hunting due to physical advantages, while women specialized in gathering and child-rearing due to the physical demands of pregnancy and nursing. This led to males evolving traits like good throwing ability, pursuit skills, and spatial reasoning suited for hunting, while females evolved to value cooperation and childcare. These evolved differences help explain why shooting and action games appeal more to males on average.

Web2.0: from "I know nothing" to "I know something" in 2 hours (what?!?)
The document discusses the concept and history of "Web 2.0". It begins with a disclaimer that Web 2.0 is an evolving buzzword trend. It then discusses how the term was coined by Tim O'Reilly in 2004 to describe websites that harness user participation and collective intelligence through open APIs and interactivity. Examples discussed include social bookmarking sites like Delicious, media sharing sites like Flickr, wikis like Wikipedia, and mashups that combine data from multiple sites. The document also notes that Web 2.0 concepts like AJAX enable more interactive and dynamic web applications.

The document discusses an experimental study comparing local and global trust metrics on the Epinions.com review community. It finds that around 17,090 users (over 20%) on Epinions are considered controversial, having at least one person who disagrees with the majority view of them. Experiments show that local trust metrics like MoleTrust2 perform better than global metrics like eBay's at predicting distrust relationships for controversial users, though error rates remain higher for these users. Further experiments vary propagation horizons and evaluate coverage. The study concludes local metrics are generally better suited to online communities where opinions of individuals can vary significantly.
