Diffusion of Electrical Current in the Experiments of Fritsch and Hitzig and Ferrier Failed to Negate Their Conclusion of the Existence of Cerebral Motor Centers

This paper explores the implications of an early criticism of the stimulation studies of Fritsch and Hitzig and Ferrier for localized brain functions. Fritsch and Hitzig and Ferrier concluded that motor centers reside in the cortices of the hemispheres. Their studies were replicated, but their conclusions were not generally accepted initially. The most salient, laboratory-based criticism was that the electrical current used for stimulation diffused well beyond the cortex making their conclusion of cerebral motor centers unacceptable. The diffusion argument was essentially a French suggestion. Ferrier's and American research and interpretations provided data and arguments against it.     

An American Controversy about the Localization of Cutaneous Sensory Regions and their Relation to Motor Regions

Three American neurologists (C. K. Mills, C. L. Dana, and M. A. Starr) explored the anatomical limits of the motor and tactile systems in the brain from 1884 to 1895. Their papers and critiques of one another show contemporary knowledge, limits of their thinking, and difficulties deciding between alternatives. The issue for them was whether there were separate sensory and motor regions or whether there was a combined sensory-motor region. They based their localization arguments on clinical and laboratory findings and on the conclusions of H. Munk and D. Ferrier. There is a discussion about why differences were unresolved.     

For the Good of The Nation: ‘Strategic Egalitarianism’ in the Singapore Context

In this article, I introduce the concept of ‘strategic egalitarianism’ in relation to women's co‐optation into nationalist projects in Singapore. By strategic egalitarianism, I mean the granting of equality to women that is contingent upon meeting particular pragmatic nationalist objectives. For example, the granting of equal educational and employment opportunities by the government in the 1960s was necessitated by Singapore's economic survival as a newly emerging nation. By the 1980s, another pragmatic national concern dealing with rapid decline in population growth emerged, requiring that women prioritise the role of motherhood. A complicating factor in the procreationist discourse is the government's eugenic policy that favours the ‘right’ kind of women, in particular, to bear the ‘right’ kind of babies for the continued vitality of the nation. In the course of this article, I examine the problem with strategic egalitarianism, which shifts its ground depending on the nationalist goals of the day, and the implications this has for Singapore women.     

Seal dies from the National Museum of Slovenia: Non-destructive analyses of medieval and early modern copper alloys

A representative group of seal dies made of copper alloys from the collection of the National Museum of Slovenia was investigated by energy-dispersive X-ray fluorescence spectrometry (EDXRF). Chronologically, the artefacts date from the early 13th century to the present. Non-destructive EDXRF screening of elemental fingerprints of Cu, Zn, Pb, Ag, Sn and Sb was performed on 95 seal dies, and the obtained elemental data set was further processed by chemometric tools such as principal component analysis (PCA). The relationships between the elemental composition of analysed seal dies, type of alloy applied and their historical context—date, location of manufacture and, possibly, social rank of the owner—were examined in detail.

Procedures and complications in late-nineteenth-century experimental neuroanatomical research exemplified by articles of Henry Herbert Donaldson (1857–1938)

Henry Herbert Donaldson (1857–1938) was a leader in neurological research in the United States for several decades, beginning about 1890. A detailed account of three of his earliest publications shows the neuroanatomical procedures involved in the study of the relation of brain and intelligence during the late-nineteenth-century in America. Two of the articles, published in September 1890 and December 1891, were titled, “Anatomical Observations on the Brain and Several Sense-Organs of the Blind Deaf-Mute, Laura Dewy Bridgman (1829–1889)”; the third, published in August 1892, used the information from the first two to delimit the extent of the visual processing area of the human cortex. Donaldson’s procedures included brain cuttings and measures of macroscopic brain structures, histology of cellular structures, attempts to relate macroscopic brain structures with brain functions, data corrections, estimations, comparisons, and statistics. These procedures provide a view of the relative thoroughness, accuracy, and comparability of the various neuroanatomical techniques in use at that time and of Donaldson’s implementation of the techniques. Donaldson’s brain cutting techniques were much more comparable than his measurement techniques. The latter could be quite precise, but they were fraught with lack of standardized procedures that made corrections and estimations necessary when making data comparisons across studies. Donaldson emphasized these incompatibilities, implying a need for standardization. Statistical procedures were the least thorough and effective. His, and the field’s, total complement of statistical techniques consisted of mean and range, which severely limited his ability to make complicated assessments. This limitation was not necessarily supplemented by stringent control group comparisons.     

Acceptance of the neuron theory by clinical neurologists of the late-nineteenth century

This article explores reactions of clinical neurologists of the late-nineteenth century to the concept of a unified nerve cell, the "neuron," which developed from the research on fine anatomy of the nervous system and from conclusions of Waldeyer based on that research. Assessment shows that Waldeyer's role in the acceptance of the neuron theory was not straightforward. A study of primarily American medical literature shows rapid acceptance, eager applications, and high expectations. Nonetheless, some clinicians were disappointed in its immediate relevance. An explanation for this disappointment is offered.     

Financing the 450 Year Road: Land Expropriation and Politics ‘All the Way Down’ in Vientiane,Laos

Over the past decade, the Lao government has developed the policy of ‘Turning Land into Capital’ (TLIC), a strategy for generating revenue and economic value from ‘state land’. The 450 Year Road Project built along the periphery of the Laotian capital, Vientiane, linking the national highway with the Thai border, was financed using a TLIC model. Additional land to the side of the road was acquired to be resold at rates significantly higher than the compensation provided to landowners. Prior to construction, however, most of the land had already been purchased by external buyers, who impeded the project's development by refusing to concede their newly purchased plots. This article contributes to the literature on political reactions ‘from below’ to land grabbing by arguing that in order to understand the operational success or failure of land development projects, it is imperative to analyse the politics that pervade such investments ‘all the way down’ — the interrelated roles, interests and relations of involved actors and groups in all positions of power within society. The 450 Year Road project stalled due to its failure to take into account the interests and politics of seemingly compliant actors, particularly landowning farm households and speculative land buyers.
