The Secret to Successful User Communities: An Analysis of Computer Associates’ User Groups

This paper provides the first large scale study that examines the impact of both individual- and group-specific factors on the benefits users obtain from their user communities. By empirically analysing 924 survey responses from individuals in 161 Computer Associates' user groups, this paper aims to identify the determinants of successful user communities. To measure success, the amount of time individual members save through having access to their user networks is used. As firms can significantly profit from successful user communities, this study proposes four key implications of the empirical results for the management of user communities

Untangling knowledge creation and knowledge integration in enterprise wikis

A central challenge organizations face is how to build, store, and maintain knowledge over time. Enterprise wikis are community-based knowledge systems situated in an organizational context. These systems have the potential to play an important role in managing knowledge within organizations, but the motivating factors that drive individuals to contribute their knowledge to these systems is not very well understood. We theorize that enterprise wiki initiatives require two separate and distinct types of knowledge-sharing behaviors to succeed: knowledge creation (KC) and knowledge integration (KI). We examine a Wiki initiative at a major German bank to untangle the motivating factors behind KC and KI. Our results suggest KC and KI are indeed two distinct behaviors, reconcile inconsistent findings from past studies on the role of motivational factors for knowledge sharing to establish shared electronic knowledge resources in organizations, and identify factors that can be leveraged to tilt behaviors in favor of KC or KI

Archaeological evidence for population rise and collapse between ~2500 and ~500 cal. yr BP in Western Central Africa: Preuve archéologique de l’augmentation et de l’effondrement de la population entre ~2500 et ~500 ans cal. BP en Afrique centrale occidentale

Palaeocological studies show that major vegetation and environmental changes occurred in Central Africa from the mid-Holocene (e.g. Maley & Brenac 1998). Several suggest a human origin and assume that large population migration, technical innovations (e.g. iron-smelting technology) and/or change in agricultural practice, leading to deforestation and land clearance, are the drivers of these changes. However, at this stage, the lack of demographic reconstruction does not fully support these hypotheses. Here, a georeferenced archaeological database is used to infer population dynamics and the evolution of cultural practices in Western Central Africa over the last 5000 years. This database includes 1139 14C calibrated dates from 425 sites throughout southern Cameroon, Gabon, the Republic of Congo, Equatorial Guinea and the western part of the Democratic Republic of Congo, dating back a maximum of 5000 cal. yr BP. Data modelling indicate possible population growth from 2500 to 1500 cal. yr BP, coinciding with the occurrence at a regional scale of specific techniques and practices. The concomitant increase of refuse pits, palm oil Elaeis guineesis and iron metallurgy (plus rare remains of millet Pennisetum glaucum) took place during the second half of the Neolithic, beginning around 2800 cal. yr BP. In the coastal regions, the population growth concerns the Neolithic and the Early Iron Age (2500–2000 cal. yr BP and 2000–1500 cal. yr BP), while in the Hinterland population growth seems slightly later (2400 and 1300 cal. yr BP). It is not possible to identify a common diffusion phenomenon from a single homeland. Rather, technical innovations and new practices appear to have spread through a wide network of cultural interactions, which fostered the formation of Western Central African societies during the third millennium

Understanding Anthropological Understanding: for a merological anthropology

In this paper I argue for a merological anthropology in which ideas of ‘partiality’ and ‘practical adequacy’ provide a way out of the impasse of relativism which is implied by post-modernism and the related abandonment of a concern with ‘truth’. Ideas such as ‘aptness’ and ‘faithfulness’ enable us to re-establish empirical foundations without having to espouse a simple realism which has been rightly criticised. Ideas taken from ethnomethodology, particularly the way we bootstrap from ‘practical adequacy’ to ‘warrants for confidence’ point to a merological anthropology in which we recognize that we do not and cannot know everything, but that we can have reasons for being confident in the little we know

Big Data and Research Opportunities Using HRAF Databases

The HRAF databases, eHRAF World Cultures and eHRAF Archaeology, each containing large corpora of curated text subject-indexed at the paragraph-level by anthropologists, were designed to facilitate rapid retrieval of information. The texts describe social and cultural life in past and present societies around the world. As of the spring of 2017, eHRAF contains almost 3 million indexed “paragraph” units from over 8,000 documents describing over 400 societies and archaeological traditions. This chapter first discusses concrete problems of scale resulting from large numbers of complex elements retrieved by any given search. Second, we discuss potential and partial solutions that resolve these problems to advance research, whether based on specific hypotheses, classification or identifying and evaluating embedded patterns of relationships. Third, we discuss new kinds of research possibilities that can be further advanced, have not yet been successfully attempted, or have not even been considered using anthropological data because of scale and complexity of achieving a result

Life-history writing and the anthropological silhouette

In this paper I explore ways in which anthropologists can and have approached life-histories. I consider some of the theoretical background to this and discuss life-writing, biography and autobiography. In conclusion, I see the life-history as grounding anthropological analysis. As a model for future work I introduce the idea of an 'anthropological silhouette': less complete than a biography, and partial, but demonstrably based on an individual, and honest about its limitations and incompleteness. © 2008 European Association of Social Anthropologists (EASA)

Gift economies in the development of open source software: Anthropological reflections

Building on Eric Raymond's work this article discusses the motivation and rewards that lead some software engineers to participate in the open source movement. It is suggested that software engineers in the open source movement may have sub-groupings which parallel kinship groups such as lineages. Within such groups gift giving is not necessarily or directly reciprocated, instead members work according to the 'axiom of kinship amity' - direct economic calculation is not appropriate within the group. What Bourdieu calls 'symbolic capital' can be used to understand how people work in order to enhance the reputation (of themselves and their group). © 2003 Elsevier Science B.V. All rights reserved

Finding meaning in the text: The process of interpretation in text-based divination

Some systems of divination are used to select particular sections of text, which are typically arcane and erudite, in which lies the answer to the particular, pressing problems of the client. Celebrated examples of such systems are the Chinese I Ching and the Yoruba Ifá. Werbner's work on Kalanga and Tswapong divination provides a case-study of the detailed praxis in such systems. Diviners have a multiple role when a divination technique selects a text. At each consultation they must satisfy themselves, their client, and their audience that they have followed the correct procedures to select the text. A second stage follows. The client has a particular question and the selected text was not composed as a specific answer to it. Interpretation is required to satisfy the client that the question has been answered. The diviner thus plays the role of indigenous critic, a role both similar to and different from that of literary critics in the Western tradition. The concept of 'dialogic' used by Barber in her analysis of Yoruba praise poetry is taken to illustrate similarities and differences between diviner and critic. © Royal Anthropological Institute 2001
