Anthropology and Open Access
While still largely ignored by many anthropologists, open access (OA) has been a confusing and volatile center around which a wide range of contentious debates and vexing leadership dilemmas orbit. Despite widespread misunderstandings and honest differences of perspective on how and why to move forward, OA frameworks for scholarly communication are now part of the publishing ecology in which all active anthropologists work. Cultural Anthropology is unambiguously a leading journal in the field. The move to transition it toward a gold OA model represents a milestone for the iterative transformation of how cultural anthropologists, along with diverse fellow travelers, communicate more ethically and sustainably with global and diverse publics. On the occasion of this significant shift, we build on the history of OA debates, position statements, and experiments taking place during the past decade to do three things. Using an interview format, we will offer a primer on OA practices in general and in cultural anthropology in particular. In doing so, we aim to highlight some of the special considerations that have animated arguments for OA in cultural anthropology and in neighboring fields built around ethnographic methods and representations. We then argue briefly for a critical anthropology of scholarly communication (including scholarly publishing), one that brings the kinds of engaged analysis for which Cultural Anthropology is particularly well known to bear on this vital aspect of knowledge production, circulation, and valuation. Our fieldâs distinctive knowledge of social, cultural, political, and economic phenomena should alsoâbut often has notâinform our choices as both global actors and publishing scholars
Open Access Publishing: A Literature Review
Within the context of the Centre for Copyright and New Business Models in the Creative Economy (CREATe) research scope, this literature review investigates the current trends, advantages, disadvantages, problems and solutions, opportunities and barriers in Open Access Publishing (OAP), and in particular Open Access (OA) academic publishing. This study is intended to scope and evaluate current theory and practice concerning models for OAP and engage with intellectual, legal and economic perspectives on OAP. It is also aimed at mapping the field of academic publishing in the UK and abroad, drawing specifically upon the experiences of CREATe industry partners as well as other initiatives such as SSRN, open source software, and Creative Commons. As a final critical goal, this scoping study will identify any meaningful gaps in the relevant literature with a view to developing further research questions. The results of this scoping exercise will then be presented to relevant industry and academic partners at a workshop intended to assist in further developing the critical research questions pertinent to OAP
Classification of cryptocurrency coins and tokens by the dynamics of their market capitalisations
We empirically verify that the market capitalisations of coins and tokens in
the cryptocurrency universe follow power-law distributions with significantly
different values, with the tail exponent falling between 0.5 and 0.7 for coins,
and between 1.0 and 1.3 for tokens. We provide a rationale for this, based on a
simple proportional growth with birth & death model previously employed to
describe the size distribution of firms, cities, webpages, etc. We empirically
validate the model and its main predictions, in terms of proportional growth
(Gibrat's law) of the coins and tokens. Estimating the main parameters of the
model, the theoretical predictions for the power-law exponents of coin and
token distributions are in remarkable agreement with the empirical estimations,
given the simplicity of the model. Our results clearly characterize coins as
being "entrenched incumbents" and tokens as an "explosive immature ecosystem",
largely due to massive and exuberant Initial Coin Offering activity in the
token space. The theory predicts that the exponent for tokens should converge
to 1 in the future, reflecting a more reasonable rate of new entrants
associated with genuine technological innovations
The political imaginaries of blockchain projects: discerning the expressions of an emerging ecosystem
There is a wealth of information, hype around, and research into blockchainâs âdisruptiveâ and âtransformativeâ potential concerning every industry. However, there is an absence of scholarly attention given to identifying and analyzing the political premises and consequences of blockchain projects. Through digital ethnography and participatory action research, this article shows how blockchain experiments personify âprefigurative politicsâ by design: they embody the politics and power structures which they want to enable in society. By showing how these prefigurative embodiments are informed and determined by the underlying political imaginaries, the article proposes a basic typology of blockchain projects. Furthermore, it outlines a frame to question, cluster, and analyze the expressions of political imaginaries intrinsic to the design and operationalization of blockchain projects on three analytic levels: users, intermediaries, and institutions.</p
Inferring short-term volatility indicators from Bitcoin blockchain
In this paper, we study the possibility of inferring early warning indicators
(EWIs) for periods of extreme bitcoin price volatility using features obtained
from Bitcoin daily transaction graphs. We infer the low-dimensional
representations of transaction graphs in the time period from 2012 to 2017
using Bitcoin blockchain, and demonstrate how these representations can be used
to predict extreme price volatility events. Our EWI, which is obtained with a
non-negative decomposition, contains more predictive information than those
obtained with singular value decomposition or scalar value of the total Bitcoin
transaction volume
Text Data Mining from the Author's Perspective: Whose Text, Whose Mining, and to Whose Benefit?
Given the many technical, social, and policy shifts in access to scholarly
content since the early days of text data mining, it is time to expand the
conversation about text data mining from concerns of the researcher wishing to
mine data to include concerns of researcher-authors about how their data are
mined, by whom, for what purposes, and to whose benefits.Comment: Forum Statement: Data Mining with Limited Access Text: National
