Relation of threatened egotism to violence and aggression: The dark side of high self-esteem.

Abstract: Conventional wisdom has regarded low self-esteem as an important cause of violence, but the opposite view is theoretically viable. An interdisciplinary review of evidence about aggression, crime, and violence contradicted the view that low self-esteem is an important cause. Instead, violence appears to be most commonly a result of threatened egotismwthat is, highly favorable views of self that are disputed by some person or circumstance. Inflated, unstable, or tentative beliefs in the self's superiority may be most prone to encountering threats and hence to causing violence. The mediating process may involve directing anger outward as a way of avoiding a downward revision of the selfconcept. Only a minority of human violence can be understood as rational, instrumental behavior aimed at securing or protecting material rewards. The pragmatic futility of most violence has been widely recognized: Wars harm both sides, most crimes yield little financial gain, terrorism and assassination almost never bring about the desired political changes, most rapes fail to bring sexual pleasure, torture rarely elicits accurate or useful information, and most murderers soon regret their actions as pointless and selfdefeating (Ford, 1985; Gottfiedson & Hirschi, 1990; Groth, 1979; Keegan, 1993; Sampson & Laub, 1993; .Scm'ry, 1985). What drives people to commit violent and oppressive actions that so often are tangential or even contrary to the rational pursuit of material self-interest? This article reviews literature relevant to the hypothesis that one main source of such violence is threatened egotism, particularly when it consists of favorable self-appraisals that may be inflated or ill-founded and that are confronted with an external evaluation that disputes them. The focus on egotism (i.e., favorable self-appraisals) as one cause of violent aggression runs contrary to an entrenched body of wisdom that has long pointed to low self-esteem as the root of violence and other antisocial behavior. We shall examine the arguments for the low self-esteem view and treat it as a rival hypothesis to our emphasis on high self-esteem. Clearly, there

Review: current international research into cellulose nanofibres and nanocomposites

Abstract: This paper provides an overview of recent progress made in the area of cellulose nanofibre-based nanocomposites. An introduction into the methods used to isolate cellulose nanofibres (nanowhiskers, nanofibrils) is given, with details of their structure. Following this, the article is split into sections dealing with processing and characterisation of cellulose nanocomposites and new developments in the area, with particular emphasis on applications. The types of cellulose nanofibres covered are those extracted from plants by acid hydrolysis (nanowhiskers), mechanical treatment and those that occur naturally (tunicate nanowhiskers) or under culturing conditions (bacterial cellulose nanofibrils). Research highlighted in the article are the use of cellulose nanowhiskers for shape memory nanocomposites, analysis of the interfacial properties of cellulose nanowhisker and nanofibril-based composites using Raman spectroscopy, switchable interfaces that mimic sea cucumbers, polymerisation from the surface of cellulose nanowhiskers by atom transfer radical polymerisation and ring opening polymerisation, and methods to analyse the dispersion of nanowhiskers. The applications and new advances covered in this review are the use of cellulose nanofibres to reinforce adhesives, to make optically transparent paper for electronic displays, to create DNA-hybrid materials, to generate hierarchical composites and for use in foams, aerogels and starch nanocomposites and the use of all-cellulose nanocomposites for enhanced coupling between matrix and fibre. A comprehensive coverage of the literature is given and some suggestions on where the field is likely to advance in the future are discussed.

To err (meiotically) is human: the genesis of human aneuploidy

Abstract: Aneuploidy (trisomy or monosomy) is the most commonly identified chromosome abnormality in humans, occurring in at least 5% of all clinically recognized pregnancies. Most aneuploid conceptuses perish in utero, which makes this the leading genetic cause of pregnancy loss. However, some aneuploid fetuses survive to term and, as a class, aneuploidy is the most common known cause of mental retardation. Despite the devastating clinical consequences of aneuploidy, relatively little is known of how trisomy and monosomy originate in humans. However, recent molecular and cytogenetic approaches are now beginning to shed light on the non-disjunctional processes that lead to aneuploidy.
