How orangutans (Pongo pygmaeus) innovate for water.
Russon, Anne E; Kuncoro, Purwo; Ferisa, Agnes; Handayani, Dwi Putri
2010-02-01
We report an observational field study that aimed to identify innovative processes in rehabilitant orangutans' (Pongo pygmaeus) water innovations on Kaja Island, Central Kalimantan, Indonesia. We tested for the basic model of innovating (make small changes to old behavior), 4 contributors (apply old behavior to new ends, accidents, independent working out, social cross-fertilization), development, and social rank. Focal observations of Kaja rehabilitants' behavior over 20 months yielded 18 probable innovations from among 44 water variants. We identified variants by function and behavioral grain, innovations by prevalence, and innovative processes by relations between innovations, other behaviors, and social encounters. Findings indicate innovating by small changes and some involvement of all 4 contributors; midrank orangutans were the most innovative; and rehabilitants' adolescent age profile, orphaning, and intense sociality probably enhanced innovativeness. Important complexities include: orangutan innovating may favor certain behavioral levels and narrowly defined similarities, and it may constitute a phase-like process involving a succession of changes and contributors. Discussion focuses on links with great ape cognition and parallels with innovating in humans and other nonhuman species.

S75-25823 (February 1975) --- Cosmonaut Aleksei A. Leonov (left) and astronaut Thomas P. Stafford display the Apollo Soyuz Test Project (ASTP) commemorative plaque. The two commanders, of their respective crews, are in the Apollo Command Module (CM) trainer at Building 35 at NASA's Johnson Space Center (JSC). Two plaques divided into four quarters each will be flown on the ASTP mission. The American ASTP Apollo crew will carry the four United States quarter pieces aboard Apollo; and the Soviet ASTP Soyuz 19 crew will carry the four USSR quarter sections aboard Soyuz. The eight quarter pieces will be joined together to form two complete commemorative plaques after the two spacecraft rendezvous and dock in Earth orbit. One complete plaque then will be returned to Earth by the astronauts; and the other complete plaque will be brought back by the cosmonauts. The plaque is written in both English and Russian. The Apollo crew will consist of astronauts Thomas P. Stafford, commander; Donald K. "Deke" Slayton, docking module pilot; Vance D. Brand, command module pilot. The Soyuz 19 crew will consist of cosmonauts Aleksei A. Leonov, command pilot; and Valeri N. Kubasov, flight engineer.

Photographic representations of women living with or beyond breast cancer have gained prominence in recent decades. Postmillennial visual narratives are both documentary projects and dialogic sites of self-construction and reader-viewer witness. After a brief overview of 30 years of breast cancer photography, this essay analyzes a collaborative photo-documentary by Stephanie Byram and Charlee Brodsky, Knowing Stephanie (2003), and a memorial photographic essay by Brodsky written ten years after Byram's death, "Remembering Stephanie" (2014). The ethics of representing women's postsurgical bodies and opportunities for reader-viewers to engage in "productive looking" (Kaja Silverman's concept) are the focal issues under consideration.

The author traces the changes in Russian psychology in the past 25 years and links these changes to the earlier Russian legacy of Lev Vygotsky (1896-1934) and Aleksei N. Leontiev (1903-1979). The move into the 21st century coincided for Russian psychology as well as for the Russian society at large with the reforms of perestroika, leading to greater openness in the academic sphere. In particular, Russian psychology was able to connect in a more free and fundamental way with its own heritage and with various developments around the world. The author discusses how these factors affected continuity and innovation with regard to the 2 dominant theoretical perspectives in Russian psychology--the cultural-historical theory of Vygotsky and the theory of activity, initially developed by Leontiev. The author argues that while there are now original and substantial shifts within Russian psychology--namely toward the new paradigm characterized by various researchers as "organic psychology," "nonclassical psychology," or even "post-non-classical" psychology--the issues of agency and meaning, which were central for the previous generation of Russian psychologists, such as Vygotsky, Leontiev, Luria, Zaporozhets, Rubinstein, and others, continue to inform the development of the discipline in the 21st century.

The strategic offense initiative? The Soviets and Star Wars

Westwick, Peter J.
2014-05-01
Historians of the Cold War have paid too little attention to Soviet fears of "space-strike weapons" - that is, possible offensive uses of President Ronald Reagan's Strategic Defense Initiative. In fifteen years or so, soldiers will no longer shoot rifles but will use some kind of lightning, some sort of a machine emitting a holocaustal electrical beam. Tell me, what can we invent in this line so as to surprise our neighbors?... Alas, we are only capable of imitating and purchasing weapons from others, and we do well if we manage to repair them ourselves. --Fyodor Dostoevsky, A Writer's Diary, 1873. [Khlinov, a physicist]: "I know that he has made an important discovery concerning the transmission of infra-red rays over a distance.... Heat waves at a temperature of a thousand degrees centigrade transmitted parallel to each other constitute a monstrous weapon of destruction and defense in time of war. The whole secret lies in the transmission of a ray that does not disperse. So far nobody has been able to do this. Judging by your story, Garin has constructed a machine that will do it. If so it is an extremely important discovery." "I've been thinking for a long time that this invention smells of higher politics," said Shelga. --Aleksei Tolstoy, The Garin Death Ray, 1927 (translated by George Hanna)

Historical aspects of the early Soviet/Russian manned space program.
West, J B
2001-10-01
Human spaceflight was one of the great physiological and engineering triumphs of the 20th century. Although the history of the United States manned space program is well known, the Soviet program was shrouded in secrecy until recently. Konstantin Edvardovich Tsiolkovsky (1857-1935) was an extraordinary Russian visionary who made remarkable predictions about space travel in the late 19th century. Sergei Pavlovich Korolev (1907-1966) was the brilliant "Chief Designer" who was responsible for many of the Soviet firsts, including the first artificial satellite and the first human being in space. The dramatic flight of Sputnik 1 was followed within a month by the launch of the dog Laika, the first living creature in space. Remarkably, the engineering work for this payload was all done in less than 4 wk. Korolev's greatest triumph was the flight of Yuri Alekseyevich Gagarin (1934-1968) on April 12, 1961. Another extraordinary feat was the first extravehicular activity by Aleksei Arkhipovich Leonov (1934-) using a flexible airlock that emphasized the entrepreneurial attitude of the Soviet engineers. By the mid-1960s, the Soviet program was overtaken by the United States program and attempts to launch a manned mission to the Moon failed. However, the early Soviet manned space program has a preeminent place in the history of space physiology.

The South Pole Telescope (SPT) has systematically identified 90 high-redshift strongly gravitationally lensed submillimeter galaxies (SMGs) in a 2500 square-degree cosmological survey of the millimeter (mm) sky. These sources are selected by their extreme mm flux, which is largely independent of redshift and lensing configuration. We are undertaking a comprehensive and systematic followup campaign to use these "cosmic magnifying glasses" to study the infrared background in unprecedented detail, inform the condition of the interstellar medium in starburst galaxies at high redshift, and place limits on dark matter substructure. Here we ask for 115.4 hours of deep Spitzer/IRAC imaging to complete our survey of 90 systems to a uniform depth of 30min integrations at 3.6um and 60min at 4.5um. In our sample of 90 systems, 16 have already been fully observed, 30 have been partially observed, and 44 have not been observed at all. Our immediate goals are to: 1) constrain the specific star formation rates of the background high-redshift submillimeter galaxies by combining these Spitzer observations with our APEX, Herschel, and ALMA data, 2) robustly determine the stellar masses and mass-to-light ratios of all the foreground lensing galaxies in the sample by combining these observations with our VLT and Gemini data, the Dark Energy Survey, and ALMA; and 3) provide complete, deep, and uniform NIR coverage of our entire sample of lensed systems to characterize the environments of high redshift SMGs, maximize the discovery potential for additional spectacular and rare sources, and prepare for JWST. This program will provide the cornerstone data set for two PhD theses: Kedar Phadke at Illinois will lead the analysis of stellar masses for the background SMGs, and Kaja Rotermund at Dalhousie will lead the analysis of stellar masses for the foreground lenses.

Human impacts on fluvial systems - A small-catchment case study

Regulations of nearly two-thirds of the rivers worldwide have considerable influences on fluvial systems. In Austria, nearly any river (or) catchment is affected by humans, e.g. due to changing land-use conditions and river engineering structures. Recent studies of human impacts on rivers show that morphologic channel changes play a major role regarding channelization and leveeing, land-use conversions, dams, mining, urbanization and alterations of natural habitats (ecomorphology). Thus 'natural (fluvial) systems' are scarce and humans are almost always inseparably interwoven with them playing a major role in altering them coincidentally. The main objective of this study is to identify human effects (i.e. different land use conditions and river engineering structures) on river bed sediment composition and to delineate its possible implications for limnic habitats. The study area watersheds of the 'Fugnitz' River (~ 140km²) and the 'Kaja' River (~ 20km²) are located in the Eastern part of the Bohemian Massif in Austria (Europe) and drain into the 'Thaya' River which is the border river to the Czech Republic in the north of Lower Austria. Furthermore the 'Thaya' River is eponymous for the local National Park 'Nationalpark Thayatal'. In order to survey river bed sediment composition and river engineering structures facies mapping techniques, i.e. river bed surface mapping and ecomorphological mapping have been applied. Additionally aerial photograph and airborne laserscan interpretation has been used to create land use maps. These maps have been integrated to a numerical DEM-based spatial model in order to get an impression of the variability of sediment input rates to the river system. It is hypothesized that this variability is primarily caused by different land use conditions. Finally river bed sites affected by river engineering structures have been probed and grain size distributions have been analyzed. With these data sedimentological and ecological
