Nonviolence and Media Studies

COMMUNICATION THEORY, Issue 2 2005
Vamsee Juluri
This article proposes a meeting of media studies and the philosophy of nonviolence in order to better critique the tendency in popular media discourses about war and international conflict to naturalize violence as an eternal and essential human trait. Nonviolence exposes certain foundational myths about violence in the media; namely, the myths that violence is cultural (as implied in the "clash of civilizations" thesis), historical, or natural. However, this is possible only if nonviolence is retrieved from its present marginalization as a mere technique for political activism or personal behavior and understood more accurately as a coherent, universal, practical worldview that can inform a critical engagement with media discourses of violence. Using Gandhi's writings on nonviolence, this essay aims to initiate such an understanding, particularly in connection with existing critical approaches to media violence, such as cultivation research and cultural studies, and concludes by proposing a set of concrete questions for media research based on nonviolence.

Brief communication: Reaction to fire by savanna chimpanzees (Pan troglodytes verus) at Fongoli, Senegal: Conceptualization of "fire behavior" and the case for a chimpanzee model

AMERICAN JOURNAL OF PHYSICAL ANTHROPOLOGY, Issue 4 2010
Jill D. Pruetz
Abstract The use and control of fire are uniquely human traits thought to have come about fairly late in the evolution of our lineage, and they are hypothesized to correlate with an increase in intellectual complexity. Given the relatively sophisticated cognitive abilities yet small brain size of living apes compared to humans and even early hominins, observations of wild chimpanzees' reactions to naturally occurring fire can help inform hypotheses about the likely responses of early hominins to fire. We use data on the behavior of savanna chimpanzees (Pan troglodytes verus) at Fongoli, Senegal during two encounters with wildfires to illuminate the similarities between great apes and humans regarding their reaction to fire. Chimpanzees' close relatedness to our lineage makes them phylogenetically relevant to the study of hominid evolution, and the open, hot and dry environment at Fongoli, similar to the savanna mosaic thought to characterize much of hominid evolution, makes these apes ecologically important as a living primate model as well. Chimpanzees at Fongoli calmly monitor wildfires and change their behavior in anticipation of the fire's movement. The ability to conceptualize the "behavior" of fire may be a synapomorphic trait characterizing the human-chimpanzee clade. If the cognitive underpinnings of fire conceptualization are a primitive hominid trait, hypotheses concerning the origins of the control and use of fire may need revision. We argue that our findings exemplify the importance of using living chimpanzees as models for better understanding human evolution despite recently published suggestions to the contrary.

Language out of Music: The Four Dimensions of Vocal Learning

THE AUSTRALIAN JOURNAL OF ANTHROPOLOGY, Issue 3 2008
Nicholas Bannan
A growing consensus drawing on research in a wide variety of disciplines has, over the last fifteen years or so, argued the need to revisit Darwin's conjecture of 1871 that language may be descended from an existing, musical medium of communication that developed from animal calls. This paper seeks to examine, in an extension of Hockett's analysis of the design features required for linguistic communication, the nature of the acoustic information produced and perceived in human vocalisation, and to consider the anatomical and neural mechanisms on which these depend. An attempt is made to sketch an evolutionary chronology for key prerequisites of human orality. Cross-species comparisons are employed to illuminate the role of four acoustic variables (pitch, duration, amplitude and timbre), viewing the potential for human vocal productivity from the perspective of animal communication. Although humans are the only species to combine entrainment to pulse with attunement to precisely-tracked pitches, we also depend both for musical interaction and the production and perception of vowel sounds on precise and conscious control of the property of timbre. Drawing on, amongst others, Scherer's analyses of emotionally triggered sounds in a variety of species, and Fernald's presentation of the similarities of infant cries and adult production of infant-directed speech in a variety of cultures and languages, a case is made for the instinctive components of human communication being more music-like than language-like. In conclusion, historical and comparative data are employed to outline the adaptive and exaptive sequence by which human vocal communication evolved. The roles of selective pressures that conform to different adaptive models are compared,natural selection, sexual selection, group selection,leading to the proposal that all of these must have played their part at different stages in the process in a ,mosaic' model consistent with the development of other human traits.

Searching for the regulators of human gene expression

BIOESSAYS, Issue 10 2006
Julian T. Forton
Many common human traits are believed to be a composite reflection of multiple genetic and non-genetic factors and the genetic contribution is consequently often difficult to characterise. Recent advances suggest that subtle variation in the regulation of gene expression may contribute to complex human traits. In two reports,1,2 Cheung and colleagues scale up human genetics analysis to an impressive level in a genome-wide search for the regulators of gene expression. They perform linkage analysis on expression profiles for over 3,500 genes and then employ the HapMap resource3 to take positive findings through to association studies at the genome-wide level. This work gives new insights into the complexities of gene regulation and the plausibility of genome-wide study design. BioEssays 28: 968,972, 2006. © 2006 Wiley Periodicals, Inc. [source]
