America's civic community from the end of the Great Depression through the post World War II years was hardly rational or racially neutral in its uneven and unequal treatment of African Americans and other underrepresented groups. Conventional civic scholarship of the era has ignored the complexities of a racially segregated society that in theory…. This well-researched volume explores how the Black freedom struggle and the anti-Vietnam War movement dovetailed with faculty and student activism in the South to undermine the traditional role of higher education and bring about social change. It uses the battles between students, faculty, presidents, trustees, elected officials, and funding….

Analogical reasoning is vital to advanced cognition and behavioral adaptation. Many theorists deem analogical thinking to be uniquely human and to be foundational to categorization, creative problem solving, and scientific discovery. Comparative psychologists have long been interested in the species generality of analogical reasoning, but they initially found it difficult to obtain empirical support for such thinking in nonhuman animals for pioneering efforts, see [2, 3]. Researchers have since mustered considerable evidence and argument that relational matching-to-sample RMTS effectively captures the essence of analogy, in which the relevant logical arguments are presented visually.

Critically, no items in the correct test pair physically match items in the sample pair, thus demanding that only relational sameness or differentness is available to support accurate choice responding. Initial evidence suggested that only humans and apes can successfully learn RMTS with pairs of sample and test items; however, monkeys have subsequently done so. Here, we report that crows too exhibit relational matching behavior.

Even more importantly, crows spontaneously display relational responding without ever having been trained on RMTS; they had only been trained on identity matching-to-sample IMTS. Such robust and uninstructed relational matching behavior represents the most convincing evidence yet of analogical reasoning in a nonprimate species, as apes alone have spontaneously exhibited RMTS behavior after only IMTS training.

The vocal characteristics and the morph of the syrinx in Carrion crows Corvus corone and those in Jungle crows C. The vocalizations of both species of crow were recorded into sonograms and analyzed. The appearance and inner configuration of the syrinx were observed using stereoscopic microscope. In addition, the inside diameter of the syrinx, the sizes of the labia and the attached position of the syringeal muscles were measured.

The attached figures of syringeal muscles were different between the two species. The vocalizations of Carrion crows were noisier than possibly because their labias were noticeably smaller than those of Jungle crows. The attachment patterns of the syringeal muscles in Jungle crows suggested that they allow for more flexibility on the inside structure of the syrinx. The inner space of the syrinx in Jungle crows was also wider than those of Carrion crows.

Jim Thomas: A Collection of Memories. His friends and colleagues from around the world have since expressed their sadness and paid tribute to a visionary scientist in multiple public forums. For those who didn't get the chance to know Jim , I share a collection of my own memories of Jim Thomas and memories from some of his colleagues.

Tool bending in New Caledonian crows. Recent field experiments have revealed that tool bending is part of the species' natural behavioural repertoire, providing important context for interpreting Betty's iconic wire-bending feat. More generally, this discovery provides a compelling illustration of how natural history observations can inform laboratory-based research into the cognitive capacities of non-human animals. We present a study of the structural organization of highly repetitive DNA in genomes of hooded crow Corvus cornix L. The family of repeats we studied had tandem organization and the same bp period of reiteration for a set of restriction enzymes.

However, in parallel to the general similarity of restriction patterns, there are species-specific peculiarities. The latter is more pronounced in nDNA of carrion crow than in that of phylogenetically distant jungle crow and closely related hooded crow. This suggests a recent amplification event for highly organized homological repeats in crow genomes. Social learning spreads knowledge about dangerous humans among American crows.

Individuals face evolutionary trade-offs between the acquisition of costly but accurate information gained firsthand and the use of inexpensive but possibly less reliable social information. American crows Corvus brachyrhynchos use both sources of information to learn the facial features of a dangerous person. An immediate scolding response to the dangerous mask after trapping by previously captured crows demonstrates individual learning, while an immediate response by crows that were not captured probably represents conditioning to the trapping scene by the mob of birds that assembled during the capture.

Later recognition of dangerous masks by lone crows that were never captured is consistent with horizontal social learning. Independent scolding by young crows , whose parents had conditioned them to scold the dangerous mask, demonstrates vertical social learning. Crows that directly experienced trapping later discriminated among dangerous and neutral masks more precisely than did crows that learned through social means.

Learning enabled scolding to double in frequency and spread at least 1. We exposed wild crows to a novel 'dangerous face' by wearing a unique mask as we trapped, banded and released birds at five study sites near Seattle, WA, USA. These field demonstrations will utilize only hot-water displacement without any chemical additives because the use of chemicals to enhance the hot-water flushing process has only been tested on a preliminary basis.

Chemicals that have been tested and that were used in these tests are totally biodegradable. The objective of this task was to obtain sufficient baseline data to show the effectiveness and environmentally safe use of chemicals, primarily surfactants, to enhance the CROW process. To meet this objective, 14 one-dimensional displacement tests were conducted. Eleven tests were conducted on a material from a former manufactured gas plant MGP site and four tests were conducted with a contaminated soil from a former wood treatment facility.

The tests investigated the effect of three chemical concentrations 0, 0. Do New Caledonian crows solve physical problems through causal reasoning? The extent to which animals other than humans can reason about physical problems is contentious. The benchmark test for this ability has been the trap-tube task. We presented New Caledonian crows with a series of two-trap versions of this problem. Three out of six crows solved the initial trap-tube.

These crows continued to avoid the trap when the arbitrary features that had previously been associated with successful performances were removed. However, they did not avoid the trap when a hole and a functional trap were in the tube. In contrast to a recent primate study, the three crows then solved a causally equivalent but visually distinct problem—the trap-table task.

Much more than documents.

The performance of the three crows across the four transfers made explanations based on chance, associative learning, visual and tactile generalization, and previous dispositions unlikely. Our findings suggest that New Caledonian crows can solve complex physical problems by reasoning both causally and analogically about causal relations. Causal and analogical reasoning may form the basis of the New Caledonian crow 's exceptional tool skills. James F. Crow : his life in public service. The readers of this journal may well be aware of Professor Crow 's scientific achievements and his role as the editor of Perspectives.

In addition, for many thousands of students at the University of Wisconsin over many generations, James F. Crow was one of the most memorable teachers at both the undergraduate and graduate levels. What is less known is his major role in public service where he served as chair of many important committees for the National Academy of Sciences, the National Institutes of Health, the National Institutes of Justice as well as various international programs. In all of these efforts, Professor Crow has left a lasting impact. He answers questions about his inspiration to become an astronaut and his career path.

Since receiving his Ph. The sheer volume of this kind of productivity is impressive enough, but when considering the diversity and detail of his work, these accomplishments seem almost superhuman. Jim studied and wrote about every planet in the solar system. For, this he was perhaps the most distinguished planetary scientist of his generation. He successfully identified the composition of Saturn's rings and Venus's clouds.

With his collaborators, he created the first detailed models for the formation of the outer planets, and the general circulation of the Martian atmosphere. His interest in Mars dust storms provided a foundation for the "nuclear winter" theory that ultimately helped shape foreign policy in the cold war era. The human biology of Jim Tanner. In , during his second year of medical training, Jim Tanner expressed the desire to work, 'where physiology, psychology and sociology meet'.

His subsequent exposure to the breadth of an American medical education and to the social and economic environment of post-war Europe distilled his belief in the importance of viewing the human in a broad context. Following his visits to the American longitudinal growth studies in Jim 's dreams of a broad scientific discipline that incorporated both the biology and ecology of the human were strengthened by an inspirational group of embryonic human biologists with whom he developed '… the new Human Biology …' from the '… Physical Anthropology of old…'.

The development of human biology over the next 50 years was shaped by the expertise and diversity of that group of visionary scientists who conceived the scientific discipline of 'human biology' in which biology, behaviour and social context define the human species. The Life and Work of Dr. More than physicians, dentists, nurses, candidates in health administration, dental hygienists, and medical technicians prepared to receive their certifications from the second-oldest historically black medical school in the country.
