The Bertrand paradox question is: “Consider a unit-radius circle for which the length of a side of an inscribed equilateral triangle equals 3 . Determine the probability that the length of a ‘random’ chord of a unit-radius circle has length greater than 3 .” Bertrand derived three different ‘correct’ answers, the correctness depending on interpretation of the word, random. Here we employ geomet...

This short take presents the process of a learning circle, underpinned by Dadirri (Ungunmeer-Baumann 1988). method was used for purposes critical reflective practice and data collection activity with non-Indigenous participants. is First Nations (Australian) term “deep listening.” The circle research occurred social welfare workers in regional health service. We found, through privileging Indig...

Recent online gaming developments and para-gaming environments, i.e., the social software tools to communicate with fellow gamers, report, discuss and disseminate assets and experience, strongly resemble social media like Facebook or Twitter. It has therefore been suggested that games like World of Warcraft, Little Big Planet, The Godfather, or The Secret World should be called “social games.” ...

Henry Fleming, the central character of Stephen Crane's (1952/1895) Civil War novel, The Red Badge of Courage, eagerly joins the Union army although he knows little about war. Only much later does he realize how ignorant he is about whether he will run when the fighting starts. This uncertainty about himself sets off a disguised but full-scale search for social comparisons until, through the gu...

A prominent researcher visited a university to give a public lecture. When a local teacher dared to ask a question, the visitor responded, ‘That was the wrong question, from the wrong person, at the wrong time. Better luck next time.’ It is not unusual to hear people who have encountered academics and the university environment telling about the scorn coming down at them from above. Non-academi...

Establishing friendship relationships on Facebook often entails information sharing which is based on the social trust and implicit contract between users and their friends. In this context, Facebook offers applications (Apps) developed by third party application providers (AppPs), which may grant access to users’ personal data via Apps installed by their friends. Such access takes place outsid...

The ‘moral circle’ is the boundary drawn around those entities in the world deemed worthy of moral consideration. Three studies demonstrate that the size of the moral circle is influenced by a decision framing effect: the incl...

the problem of the hermeneutical circle is one of the contentious issues in philosophical hermeneutics. this paper, begins with focusing on the question as to whether what hermeneuts mean by a hermeneutical circle is in fact a real circle with no analogical sense involved. recognizing that this problem is not confined to the relation between part and whole, this study confines itself to explore...

The tension between efficiency and equilibrium is a central feature of economic systems. In many contexts, social networks mediate this trade-off: an individual's network position determines equilibrium play, and social relations allow coordination on an efficient norm. We examine this trade-o in a network game with a unique Nash equilibrium, but such that agents can achieve a higher payoff by ...

Innnite sphere packings give information about the structure but not about the shape of large dense sphere packings. For periodic sphere packings a new method was introduced in W2], W3], S] and BB], which gave a direct relation between dense periodic sphere packings and the Wull{shape, which describes the shape of ideal crystals. In this paper we show for the classical Penrose tiling that dense...
