The transition from animal spirits to animal electricity: a neuroscience paradigm shift

The Animal Spirits Paradigm had been in place for over a thousand years as a general way of looking at the nervous system, and was completely ingrained into the fabric of scientific thinking. However, the community of researchers in the 17th and 18th centuries abandoned their long-held assumptions, and started anew with the novel assertion that the currency of nervous function was, instead of Animal Spirits, a uniquely amimal electricity. This conceptual rearrangement represented a scientific revolution in thinking, a change in absolute perspective that required the reinterpretation of old data within a completely novel framework. The manner in which this transition occurred followed the general form of scientific paradigm shifts as outlined by Thomas Kuhn (Kuhn, 1962)     

Early contributions to the reflex chain hypothesis

The reflex chain hypothesis was developed to explain the observation that successive movements could be linked together into a contiguous sequence. From the established principles of reflex physiology and association psychology, scientists in the last half of the 19th century began to develop the notion that each of a series of movements may be linked through the sensory results of prior movements. In addition, the same basic principles were applied to mental actions, thus providing a credible explanation for all behavior. The wide applicability of this hpothesis made it an important influence on the scientific thought in the early 20th century.     

The Transition to History in Southeast Asia: An Introduction

Studies of the transition from prehistory to history in Southeast Asia have traditionally relied primarily on documentary sources, which tend to emphasize foreign influences, rather than on the archaeological record, which suggests a series of indigenous developments. The papers in this journal issue and the next discuss strategies for using both documentary and archaeological evidence to study the transition to history and the emergence of early states in the region. These papers investigate how political units were structured and integrated in Cambodia, Thailand, Malaysia, the Philippines, and South China, and illustrate how historical and archaeological data can cross-check each other to inform on Southeast Asian sociopolitical and economic developments during the early historic period.     

GEOPHYSICAL SURVEY AT BODEN VEAN,CORNWALL, INCLUDING AN ASSESSMENT OF THE MICROGRAVITY TECHNIQUE FOR THE LOCATION OF SUSPECTED ARCHAEOLOGICAL VOID FEATURES*

A geophysical survey was conducted at Boden Vean, St. Anthony Meneage, Cornwall, over the site of a buried chamber thought to be the remains of a souterrain or fogou. A combination of geophysical techniques was successfully applied including an experimental microgravity survey over the location of the buried chamber itself. Magnetometer survey revealed a complex palimpsest of archaeological activity extending throughout the surrounding landscape, centred on a rectangular ditched enclosure containing the fogou. A series of gravity anomalies were recorded in the vicinity of the latter which were consistent with the collapsed section of the feature recorded by the Cornish Archaeological Unit. Further gravity anomalies suggested the presence of additional void features, possibly related to the extended passages of the fogou.     

PRE-COLUMBIAN METALLURGY: TECHNOLOGY,MANUFACTURE, AND MICROPROBE ANALYSES OF COPPER BELLS FROM THE GREATER SOUTHWEST*

Twenty-four cast copper crotals (commonly called bells), one 'spilled bell’, one tinkler bell and a number of minerals from locations throughout the Greater Southwest were analysed for their elemental composition by a PIXE nuclear microprobe at Los Alamos National Laboratory, New Mexico, USA. Sixteen bells contained minor and trace amounts of silver, antimony, arsenic, lead, and in some cases tin, strontium, and selenium. Nine bells contained little or no detectable amounts of these elements. This suggests that several workshops throughout the Greater Southwest and Mexico might have manufactured these bells.     

Solution Techniques for Large Regional Partitioning Problems

This paper presents procedures for use in electoral districting and related applications. A region is to be divided into a number of “territories” formed as aggregates of discrete spatial units, subject to constraints on territory size and on intraterritorial connectivity, so as to minimize the total length of territory perimeters. The procedures are based on a hill-climbing principle, with progressively rigorous application of the connectivity and territory-size constraints. Computational tests indicate that the best of the procedures provide an effective trade-off between solution quality and computational efficiency.     

The late prehistory of xinjiang in relation to its neighbors

Recent research by Chinese archaeologists has identified many late prehistoric (2000-400 B.C.) oases, pastoral settlements, and cemeteries in eastern Central Asia (Xinjiang province of China). The synthesis presented here organizes the data into 10 archaeological cultures, defined on the basis of ceramics, burials, small finds, and architecture. The archaeological cultures reveal two periods, corresponding to the Bronze Age and the Iron Age. The oases cultures formed a core area before the Chinese Han period and maintained close contacts with nearby highland pastoralists in Siberia and western Central Asia. The evidence for interaction between Xinjiang and the complex cultures in China and western Central Asia is evaluated with regard to the origins of the early Xinjiang cultures.     

Birth control,population control,and family planning: an overview

This overview of the US birth control movement reflects on the emergence of family planning policy due to the efforts of Margaret Sanger, feminists, and the civil rights movement, the eugenics motive to limit "deviant" populations, and the population control movement, which aims to solve social and economic problems through fertility control. Population control moved through three stages: from the cause of "voluntary motherhood" to advance suffrage and women's political and social status, to the concept of "birth control" promoted by socialist feminists to help empower women and the working class, to, from 1920 on, a liberal movement for civil rights and population control. Physicians such as Dr. Robert Latou Dickinson legitimized the movement in the formation of the Committee on Maternal Health in 1925, but the movement remained divided until 1939, when Sanger's group merged with the American Birth Control League, the predecessor of the present Planned Parenthood Federation of America. A key legal decision in 1939 in the United States v. One Package amended the Comstock Act and allowed for the distribution of birth control devices by mail to physicians. Sanger, after a brief retirement, formed the International Planned Parenthood Federation and supported research into the pill. Eugenicists through the Committee on Maternal Health supported Christopher Tietze and others developing the pill. Final constitutional access to contraception based on the right to privacy was granted in Griswold v. Connecticut. The ruling in Eisenstadt v. Baird in 1972 extended this right to unmarried persons. The right to privacy was further extended in the Roe v. Wade decision in 1973 on legal abortion. The argument for improving the quality of the population remained from the formation of the Population Reference Bureau in 1929 through the 1960s. Under the leadership of Rockefeller, population control was defined as justified on a scientific and humanitarian basis. US government support for national and international family planning proceeded slowly through the 1950s, 1960s, and 1970s. Congress during 1967-70 enacted strong legislation in support of national and international family planning. The Bucharest conference in 1974 highlighted the inadequacies of international population control that deemphasized economic development. Polarization and divisiveness on population policy persists.
