Of approximately 40 billion photos posted on Instagram, only 282 million are selfies—just 0.7%. Thus, for all its zeitgeisty appeal, the selfie is in fact a niche phenomenon in the larger context of Instagram genres. Noting this fact, we identified an opportunity to engage with scholars from all over the world with the challenge of proposing new theories and approaches capable of unlocking the full socio-anthropological potential of Instagram. As the articles collected in this special issue testify, Instagram has an enormous impact on people’s everyday lives on many levels—socially, culturally, economically, and politically—and so, indubitably, it deserves rigorous academic attention. Given the scale and complexity of these impacts, studying Instagram poses different kinds of challenges and many gaps are still to be filled. With this special issue we don’t claim to resolve all the issues noted above. More modestly, our goal is to kick-start a fruitful conversation among social media scholars interested in furthering Instagram studies.
We present a notational analysis of offensive tactics commonly employed in elite men's water polo and address three questions related to this objective: which tactics are most effective?, which tactical performance indicators best classify the winning team?, and how accurate are predictive models based on these performance indicators? We define a new statistic, Efficiency Rating, which quantifies the importance of a tactic via a weighted average of direct and indirect goals generated by its use. By this measure, direct shot is the most efficient even strategy despite being employed far less frequently than centre or perimeter tactics. We address our second question by measuring the effect size of winning over losing teams for 25 tactical variables and find that exclusion conversion rate is the most effective discriminatory statistic in both close and unbalanced games, correctly classifying almost 90% of all contests. To address our third question, we develop and apply a simple Binomial model based on goals generated per play which correctly predicts all eight games in the medal round of the 2012 Men's Olympics from preliminary rounds. Success probabilities are computed based on a weighted average of offensive and defensive efficiency with an optimal weight that favors defense.
This paper explores the notion of whakapapa as providing a legitimate research framework for engaging in research with Māori communities. By exploring the tradition and meaning of whakapapa, the paper will legitimate how whakapapa and an understanding of whakapapa can be used by Māori researchers working among Māori communities. Therefore, emphasis is placed on a research methodology framed by whakapapa that not only authenticates Māori epistemology in comparison with Western traditions, but that also supports the notion of a whakapapa research methodology being transplanted across the Indigenous world; Indigenous peoples researching among their Indigenous communities. Consequently, Indigenous identity is strengthened as is the contribution of the concept of whakapapa to Indigenous research paradigms worldwide.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
