Ethnographies of social enterprise

Purpose – As a critical and intimate form of inquiry, ethnography remains close to lived realities and equips scholars with a unique methodological angle on social phenomena. This paper aims to explore the potential gains from an increased use of ethnography in social enterprise studies. Design/methodology/approach – The authors develop the argument through a set of dualistic themes, namely, the socio-economic dichotomy and the discourse/practice divide as predominant critical lenses through which social enterprise is currently examined, and suggest shifts from visible leaders to invisible collectives and from case study-based monologues to dialogic ethnography. Findings – Ethnography sheds new light on at least four neglected aspects. Studying social enterprises ethnographically complicates simple reductions to socio-economic tensions, by enriching the set of differences through which practitioners make sense of their work-world. Ethnography provides a tool for unravelling how practitioners engage with discourse(s) of power, thus marking the concrete results of intervention (to some degree at least) as unplannable, and yet effective. Ethnographic examples signal the merits of moving beyond leaders towards more collective representations and in-depth accounts of (self-)development. Reflexive ethnographies demonstrate the heuristic value of accepting the self as an inevitable part of research and exemplify insights won through a thoroughly bodily and emotional commitment to sharing the life world of others. Originality/value – The present volume collects original ethnographic research of social enterprises. The editorial develops the first consistent account of the merits of studying social enterprises ethnographically

Probabilities, methodologies and the evidence base in existential risk assessments

This paper examines and evaluates a range of methodologies that have been proposed for making useful claims about the probability of phenomena that would contribute to existential risk. Section One provides a brief discussion of the nature of such claims, the contexts in which they tend to be made and the kinds of probability that they can contain. Section Two provides an overview of the methodologies that have been developed to arrive at these probabilities and assesses their advantages and disadvantages. Section Three contains four suggestions to improve best practice in existential risk assessment. These suggestions centre on the types of probabilities used in risk assessment, the role of methodology rankings including the ranking of probabilistic information, the extended use of expert elicitation, and the use of confidence measures to better communicate uncertainty in probability assessments. Finally, Section Four provides an annotated literature review of catastrophic and existential risk probability claims as well as the methodologies that were used to produce each of them

INCREASING AD DETECTION RELIABILITY BY LEARNING PER-CHANNEL TEMPLATES AND TRANSFORMATION

Content generators, such as video producers and advertisers, can provide their content to TV networks and other publishers for display. Automatically determining if the provided content appeared on a specific TV network can be difficult. Matching captured frames from the video streamed by the TV networks to frames from the provided content can result in a low match rate. The match rate can be low because the TV networks often apply various image transformations, such as scalings, croppings, color transformations, and overlays such as logos, tickers and other on-screen graphics that can obscure the content. When the transformations are applied, the frame images ultimately displayed by the publisher don’t match the original frame images. The present paper discusses a system and method for determining, on a channel by channel basis, transformations and overlays that are applied by TV networks

Distribution of Phoxinus eos, Phoxinus neogaeus, and Their Asexually-Reproducing Hybrids (Pisces: Cyprinidae) in Algonquin Provincial Park, Ontario

Hybrid Phoxinus are one of the few asexually reproducing vertebrates species. The distribution of hybrid Phoxinus among lakes in Algonquin Park, Ontario, was evaluated relative to the distribution of parental species and relative to physiochemical lake characteristics. No association between the distribution of hybrids and the distribution of parental species was found, suggesting that the hybrids can successfully coexist with either parental species. In addition, we found no association between hybrid distribution and the physiochemical characteristics of lakes, suggesting that the hybrids are generalists with respect to the ecological niches available in Algonquin Park. There was a difference between the physiochemical characteristics of lakes with and without the parental species P. neogaeus. The lakes containing P. neogaeus were lower elevation than the lakes containing the other parental species, P. eos. The difference in distribution between the parental species may therefore be due to different dispersal abilities, to later arrival following post-glacial dispersal, or to differences in ecology. These results suggest that asexual reproduction is a successful strategy for hybrid Phoxinus in Algonquin Park because these sperm-dependent asexual hybrids are able to survive and persist regardless of which parental species is present, and regardless of the physiochemical characteristics of their habitat
