Inertia and change in the constellation of international governmental organizations, 1981–1992

Abstract: Hardly anyone expects public institutions to die. Yet a census reveals that fully one-third of the international governmental organizations (IGOs) in existence in 1981 had in fact become defunct by 1992. Most Eastern bloc and many regional developing country organizations vanished or became inactive. During this period a slightly larger number of new organizations was born. Not governments but other IGOs spawned most of the new offspring. Wealthy democratic countries increased their IGO memberships while poor unstable countries increasingly dropped out. This bifurcation was accompanied by greater reliance by all on a set of core universal-membership institutions dominated by Western values. Functionalism, organizational ecology, and realism each partly help us to understand these trends but leave important dynamics unexplained.

Studies in scientific collaboration Part III. Professionalization and the natural history of modern scientific co-authorship

Abstract: A review of selected parameters of the growth of scientific collaboration over the last century provides further confirmation of the dependency of teamwork on the increasing professionalization of science. Analysis reveals significant inaccuracies in current views of the recency and prevalence of collaborative research, and affords a more correct picture of twentieth century developments. A change in the growth rate of the practice of scientific collaboration at about the time of World War I, and indications of associations of teamwork with financial support and research publication in leading journals are discussed. Characteristics of the natural history of scientific collaboration signify that collaboration reflects relationships of dependency within a hierarchically stratified professional community, and serves as a means of professional mobility. As such, it continues to fulfil its original functions.

Defense mechanisms in psychology today. Further processes for adaptation.

Abstract: Although the concept of the defense mechanism was rejected from academic psychology for a number of years, recent empirical studies show renewed interest in defenses. Cognitive psychologists have confirmed the existence of unconscious psychological processes, a requisite for defenses. Developmental, personality, and social psychologists have all found evidence for defense mechanisms that explicate psychological functioning. The relevance of this new information for clinical practice is discussed.

Fish and ships: relating dispersal frequency to success in biological invasions

Abstract: Most studies characterizing successful biological invaders emphasize those traits that help a species establish a new population. Invasions are, however, multi-phase processes with at least two phases, dispersal and introduction, that occur before establishment. Characteristics that enhance survival at any of these three phases will contribute to invasion success. Here, we synthesize information on the dispersal, introduction, and establishment of fishes mediated by ship ballast-water transport. We synthesize 54 reports of at least 31 fish species collected from ballast tanks (Phase 1), including 28 new reports from our recent studies (1986 to 1996). Our literature survey revealed 40 reports of 32 fish species whose introductions have been attributed to ballast transport (Phase 2), of which at least 24 survived to establish persistent populations (Phase 3). We detected little overlap at the species level between these two data sets (Phase 1 vs Phases 2 and 3), but patterns emerged at the family level. The Gobiidae (6 species), Clupeidae (4 species), and Gasterosteidae (1 species) were the most commonly found fish families in ballast tanks (Phase 1). The Gobiidae (13 species), Blenniidae (6 species) and Pleuronectidae (2 species) dominated the list of ballast-mediated introductions (Phase 2); gobies and blennies were the families most frequently established (Phase 3). The invasive success of gobies and blennies may be explained in part by their crevicolous nature: both groups seek refuge and lay eggs in small holes, and may take advantage of the ballast-intake holes on ship hulls. This behavior, not typically associated with invasive ability, may contribute to successful introduction and establishment by facilitating the dispersal phase of invasion. The failure of the pleuronectids to invade may reflect poor salinity match between donor and recipient regions. To develop a predictive framework of invasion success, organisms must be sampled at all three phases of the invasion process. Our comparison of two ballast sampling methods suggests that fishes have been undersampled in ballast-water studies, including our own, and that the role of ballast transport in promoting fish invasions has been underestimated.
