[source] REASONS-RESPONSIVENESS, ALTERNATIVE POSSIBILITIES, AND MANIPULATION ARGUMENTS AGAINST COMPATIBILISM: REFLECTIONS ON JOHN MARTIN FISCHER'S MY WAY.ANALYTIC PHILOSOPHY, Issue 3 2006Derk Pereboom First page of article [source] The Late Prehistoric,Early Historic Game Sink in the Northwestern United StatesCONSERVATION BIOLOGY, Issue 1 2002R. Lee Lyman The number of big game killed by the Corps of Discovery in 1805,1806 and recorded by Lewis and Clark suggests that ungulates were abundant in central and eastern Montana and rare in western Montana, central Idaho, and southeastern Washington during the early nineteenth century. Paleoecologists Paul Martin and Chris Szuter conclude that this difference was a function of human predation. They support their conclusion that ungulates would have been abundant in southeastern Washington had humans not hunted them by arguing that the nineteenth-century livestock industry was successful without supplemental feeding. The livestock industry was, however, not consistently successful until artificial feeding was initiated. Archaeological data from eastern Washington indicate that ungulates have been taken by human hunters more frequently than small-mammal prey throughout the last 10,000 years and that ungulates decreased relative to small mammals coincident with changes in climate. Bison ( Bison bison) and elk (Cervus canadensis) were present in eastern Washington throughout the Holocene, but bison were abundant there only during a cooler and moister period; elk have been abundant only in the twentieth century, subsequent to transplants and the extermination of predators. Geographic variation in the abundance of bison across Montana, Idaho, and eastern Washington has been influenced by human predation but has also been influenced by biogeographic history, habitat differences, and climatic change. Resumen: Los datos históricos proveen información valiosa sobre las estructuras de los ecosistemas, sus funciones y procesos. El número de animales de caza grandes que fueron sacrificados por las tropas de descubrimiento en 1805-1806 y registradas por Lewis y Clark sugieren que los ungulados eran abundantes en Montana central y oriental y raros en Montana occidental, Idaho central y el sudeste de Washington durante los inicios del siglo diecinueve. Los paleontólogos Paul Martin y Chris Szuter concluyen que esta diferencia fue causada por la depredación humana. Ellos apoyan su conclusión de que los ungulados podrían haber sido abundantes en el sudeste de Washington si los humanos no los hubieran cazado argumentando que la industria de la ganadería del siglo diecinueve exitosa sin alimento suplementario. Sin embargo, la industria de la ganadería no fue consistentemente exitosa hasta que se inició la alimentación artificial. Los datos arqueológicos de Washington oriental indican que los ungulados fueron eliminados por los cazadores humanos mas frecuentemente que las presas pequeñas de mamíferos a lo largo de los últimos 10,000 años y que la disminución de ungulados, relativa a la de mamíferos pequeños coincidió con cambios en el clima. El bisonte (Bison bison) y el alce (Cervus canadiensis) estuvieron presentes en Washington oriental a lo largo del Holoceno, pero los bisontes fueron abundantes solo durante un periodo mas frío y húmedo; los alces habían sido abundantes solo en el siglo veinte subsecuente a los transplantes y a la exterminación de los depredadores. La variación en la abundancia de alces a lo largo de Montana, Idaho y el oriente de Washington estuvo influenciada por la depredación humana, pero también por la historia biogeográfica, las diferencias en hábitat y el cambio climático.

Method:, We performed a systematic review and a meta-analysis of the rTMS studies on depression published in the past 12 months comparing these results with an earlier meta-analysis that analyzed the results of the initial rTMS studies on depression. Results:, Using our inclusion criteria, we selected the meta-analysis of Martin [Br J Psychiatry (2003) Vol. 182, 480,491] that included 13 studies (324 patients) and five studies for the recent meta-analysis (274 patients). The pooled effect size (standardized mean difference between pretreatment vs. post-treatment) from the random effects model was ,0.76 (95% confidence interval, CI, ,1.01 to ,0.51). This result was significantly larger than that of the earlier meta-analysis (,0.35, 95% CI ,0.66 to ,0.04). Conclusion:, Our findings suggest that recent rTMS clinical trials have shown larger antidepressant effects when compared with the earlier studies. [source] The first two centuries of Saint Martin of ToursEARLY MEDIEVAL EUROPE, Issue 2 2006Allan Scott McKinley This paper presents a critical examination of the evidence for the cult of St Martin in the fifth and sixth centuries. Through examination of the various manifestations of Martin's cult, it argues that the cult had different meanings and significance at different times and places, and that the commonly perceived popularity of Martin's cult was in fact an illusion created by the constant reinvention and promotion of various interpretations of Martin by interested parties, from aristocratic ascetics to politically active bishops. [source] Critical Thinking and LearningEDUCATIONAL PHILOSOPHY AND THEORY, Issue 4 2007Mark Mason Abstract This paper introduces some of the debates in the field of critical thinking by highlighting differences among thinkers such as Siegel, Ennis, Paul, McPeck, and Martin, and poses some questions that arise from these debates. Does rationality transcend particular cultures, or are there different kinds of thinking, different styles of reasoning? What is the relationship between critical thinking and learning? In what ways does the moral domain overlap with these largely epistemic and pedagogical issues? The paper concludes by showing how Peters, Evers, Chan and Yan, Ryan and Louie, Luntley, Lam, Doddington, and Kwak, respond to these questions. [source] EDUCATING COMMUNAL AGENTS: BUILDING ON THE PERSPECTIVISM OF G.H. MEADEDUCATIONAL THEORY, Issue 4 2007Jack Martin In this essay, Jack Martin aims to remedy such oversight by interpreting Mead's social-psychological and educational theorizing of selfhood and agency through the lenses of the perspectival realism Mead developed in the last decade of his life. This interpretation understands education as concerned with the cultivation and coordination of cultural, societal, interpersonal, and personal perspectives. Within this framework, communal agency is understood as a self-interpreting, self-determining capability of persons. This agentive capability derives from immersion and participation with others within sociocultural practices and perspectives, but also includes reactivity to those same practices and perspectives. The education of communal agents as envisioned here emphasizes the social nature of education, students' experience and development, and the critical role of the teacher as a mediator between student development and social process. Such an education is grounded in the immediate experiences and perspectives of learners, but increasingly assists learners to move beyond their own experiences through engaged interaction with others and with resources for acquiring broader, more organized perspectives on themselves, others, and the world. [source] "A mercer ye wot az we be": The Authorship of the Kenilworth Letter ReconsideredENGLISH LITERARY RENAISSANCE, Issue 2 2008Elizabeth Goldring The authorship of the Kenilworth Letter, an account of the festivities staged at Kenilworth Castle during Queen Elizabeth I's 1575 progress, has long been a matter of debate, with some scholars suggesting that the work was a pseudonymous hoax foisted upon an unwitting Robert Langham. New findings, together with a re-examination of the existing evidence, suggest the following: first, that the Letter began life as a bona fide missive from Langham to his fellow mercer Humphrey Martin, which, though envisioned for circulation in manuscript, was almost certainly not , in the first instance at least , intended for publication; and second, that William Patten, to whom the Letter sometimes has been attributed in the past, may have been instrumental in the initial efforts to print the work, albeit without Langham's knowledge or permission. Also considered is the wider context of Elizabethan mercery, with particular reference to the close (but often overlooked) political, economic, and cultural ties between the court and the City of London. In addition, this article explores the extent to which the Letter offers a reliable guide to the people, places, and events it describes. [source] Elements of a neurobiological theory of hippocampal function: the role of synaptic plasticity, synaptic tagging and schemasEUROPEAN JOURNAL OF NEUROSCIENCE, Issue 11 2006R. G. M. MorrisArticle first published online: 8 JUN 200 Abstract The 2004 EJN Lecture was an attempt to lay out further aspects of a developing neurobiological theory of hippocampal function [Morris, R.G.M., Moser, E.I., Riedel, G., Martin, S.J., Sandin, J., Day, M. & O'Carroll, C. (2003) Phil. Trans. R. Soc. Lond. B Biol. Sci., 358, 773,786.] These are that (i) activity-dependent synaptic plasticity plays a key role in the automatic encoding and initial storage of attended experience; (ii) the persistence of hippocampal synaptic potentiation over time can be influenced by other independent neural events happening closely in time, an idea with behavioural implications for memory; and (iii) that systems-level consolidation of memory traces within neocortex is guided both by hippocampal traces that have been subject to cellular consolidation and by the presence of organized schema in neocortex into which relevant newly encoded information might be stored. Hippocampal memory is associative and, to study it more effectively than with previous paradigms, a new learning task is described which is unusual in requiring the incidental encoding of flavour,place paired associates, with the readout of successful storage being successful recall of a place given the flavour with which it was paired. NMDA receptor-dependent synaptic plasticity is shown to be critical for the encoding and intermediate storage of memory traces in this task, while AMPA receptor-mediated fast synaptic transmission is necessary for memory retrieval. Typically, these rapidly encoded traces decay quite rapidly over time. Synaptic potentiation also decays rapidly, but can be rendered more persistent by a process of cellular consolidation in which synaptic tagging and capture play a key part in determining whether or not it will be persistent. Synaptic tags set at the time of an event, even many trivial events, can capture the products of the synthesis of plasticity proteins set in train by events before, during or even after an event to be remembered. Tag,protein interactions stabilize synaptic potentiation and, by implication, memory. The behavioural implications of tagging are explored. Finally, using a different protocol for flavour,place paired associate learning, it is shown that rats can develop a spatial schema which represents the relative locations of several different flavours of food hidden at places within a familiar space. This schema is learned gradually but, once acquired, enables new paired associates to be encoded and stored in one trial. Their incorporation into the schema prevents rapid forgetting and suggests that schema play a key and hitherto unappreciated role in systems-level memory consolidation. The elements of what may eventually mature into a more formal neurobiological theory of hippocampal memory are laid out as specific propositions with detailed conceptual discussion and reference to recent data. [source] Frontier Masculinity in the Oil Industry: The Experience of Women EngineersGENDER, WORK & ORGANISATION, Issue 1 2004Gloria E. Miller This study contributes to the empirical evidence in the area of gendered organizations (Martin and Collinson, 2002) and their effects on the women who work in them through an interpretive, ethnographic analysis of the oil industry in Canada, specifically Alberta. The study combines data from interviews with women professionals who have extensive employment experience in the industry, a historical analysis of the industry's development in the area and the personal contextual experience of the author. It is suggested that there are three primary processes which structure the masculinity of the industry: everyday interactions which exclude women; values and beliefs specific to the dominant occupation of engineering which reinforce gender divisions; and a consciousness derived from the powerful symbols of the frontier myth and the romanticized cowboy hero. In this dense cultural web of masculinities, the strategies that the women developed to survive, and, up to a point, to thrive, are double-edged in that they also reinforced the masculine system, resulting in short-term individual gains and an apparently long-term failure to change the masculine values of the industry.

[source] Irigaray's To Be Two: The Problem of Evil and the Plasticity of IncarnationHYPATIA, Issue 1 2003ADA S. JAARSMA Increasingly, feminist theorists, such as Alison Martin and Ellen T. Armour, are attending to the numerous religious allusions within texts by Luce Irigaray. Engaging with this scholarship, this paper focuses on the problematic of evil that is elaborated within Irigarayan texts. Mobilizing the work of Catherine Malabou, the paper argues that Malabou's methodology of reading, which she identifies as "plastic," illuminates the logic at work within Irigaray's deployment of sacred stories.

This porous membrane serves as the host for the template-synthesis of V2O5 nanowires of various diameters. Nanowires that are 70,nm in diameter are shown in the inset. Because V2O5 reversibly intercalates Li-ions, it has potential for use as a cathode material in Li-ion batteries. On p.,125, Sides and Martin report the use of these V2O5 nanowires as tools to investigate the poor low-temperature performance of Li-ion batteries. [source] Low-complexity unambiguous acquisition methods for BOC-modulated CDMA signalsINTERNATIONAL JOURNAL OF SATELLITE COMMUNICATIONS AND NETWORKING, Issue 6 2008Elena Simona Lohan Abstract The new M-code signals of GPS and the signals proposed for the future Galileo systems are of split-spectrum type, where the pseudorandom (PRN) code is multiplied with rectangular sub-carriers in one or several stages. Sine and cosine binary-offset-carrier (BOC) modulations are examples of modulations, which split the signal spectrum and create ambiguities in the envelope of the autocorrelation function (ACF) of the modulated signals. Thus, the acquisition of split-spectrum signals, based on the ambiguous ACF, poses some challenges, which might be overcome at the expense of higher complexity (e.g. by decreasing the step in searching the timing hypotheses). Recently, two techniques that deal with the ambiguities of the ACF have been proposed, and they were referred to as ,sideband (SB) techniques' (by Betz, Fishman et al.) or ,BPSK-like' techniques (by Martin, Heiries et al.), since they use SB correlation channels and the obtained ACF looks similar to the ACF of a BPSK-modulated PRN code. These techniques allow the use of a higher search step compared with the ambiguous ACF situation. However, both these techniques use SB-selection filters and modified reference PRN codes at the receivers, which affect the implementational complexity. Moreover, the ,BPSK-like' techniques have been so far studied for even BOC-modulation orders (i.e. integer ratio between the sub-carrier frequency and the chip rate) and they fail to work for odd BOC-modulation orders (or equivalently for split-spectrum signals with significant zero-frequency content). We propose here three reduced-complexity methods that remove the ambiguities of the ACF of the split-spectrum signals and work for both even and odd BOC-modulation orders. Two of the proposed methods are extensions of the previously mentioned techniques, and the third one is introduced by the authors and called the unsuppressed adjacent lobes (UAL) technique. We argue via theoretical analysis the choice of the parameters of the proposed methods and we compare the alternative methods in terms of complexity and performance.

Pondella II Abstract Aim, To examine the uniqueness and relationship of islands in the San Diegan Province using reef fishes. Location, Pacific coast of Baja and Southern California. Methods, Quantitative scuba surveys and statistics were used. Between June 2000 and August 2002, the nearshore rocky-reef fishes of eight southern California and Baja California islands were quantitatively surveyed. The islands surveyed were: Santa Cruz, San Nicolas, Santa Barbara, Santa Catalina, San Clemente, North Coronado, San Martin and San Benito. These islands span the latitudinal range of offshore islands within the San Diegan marine province. This regional scale approach provided not only the first quantitative description of rocky-reef fishes at five of these islands, but also allowed comparisons with known biogeographical patterns. Results, Here we discuss the distribution and abundance of 84 conspicuous rocky-reef fishes from 35 families. In general, the richness, diversity and composition of fish assemblages at these islands were found to reflect previously described biogeographical processes. The rocky reef fish assemblages of all islands in the survey were found to be significantly distinctive form each other. Phenetic analyses revealed two clusters. San Clemente, Santa Catalina and North Coronado clustered as a warm-water assemblage in the middle of the San Diegan Province. The remaining islands grouped together as a cold-water assemblage, despite the geographically disjunct position of the islands within this cluster. The relatedness of islands was independent of distance. Examination of the most common fish species at all islands revealed that while some conformed to the north,south trending density distributions predicted by previous investigators, the distribution of others could not be explained by latitude or temperature regimes. No single pattern explained the density of fishes at all islands. Both the rock croaker, Pareques sp., and flag cabrilla, Epinephelus labriformis, were observed at San Benito during these surveys, representing northern range extensions and may be indicators of the warming trend observed in this marine province. Main conclusion, For nearshore rocky-reef fishes, the islands of the San Diegan marine province are distinct and their interrelatedness is independent of the distance between them. [source] Aggressive behavior in children's dolls' house playAGGRESSIVE BEHAVIOR, Issue 6 2004*Article first published online: 25 OCT 200, Maria A. Tallandini Abstract The present study addressed the question of whether there are gender and age differences in aggressive behavior when it is studied as the spontaneous expression of mental contents and not as the result of immediate social interaction. This study also investigated whether aggression, in terms of mental content, is related to temperamental aspects. Aggressive behaviors were examined in make-believe play, in relation to age, gender, and temperament in a near-ecological context, i.e., the Dolls' House Play. The participants, 55 boys and 47 girls, subdivided into three age levels (4 years,4 years and 6 months; 5,6 years; and 7 years and 6 months,8 years and 6 months) were requested to represent what happens in their family 1) during Mealtimes; 2) at Bedtime; 3) on the Saddest day; and 4) the Happiest day; their Dolls' House Play was then recorded. Children's temperaments were measured with the TABC-Teachers' form [Martin, The Temperament Assessment Battery for Children, Brandon, VT: Clinical Psychology Publishing, 1998]. Data analysis was conducted considering aggressive behaviors in their distinct expressions,physical, verbal, direct, and indirect. Results revealed no statistical differences between boys and girls when all aggressive behaviors were compounded. However, when the distinct types of aggressiveness were considered, boys presented statistically higher levels of physical aggression than girls did. Moreover, boys and girls reacted with different types of aggression in the different emotional contexts created by the four episodes. Few age differences were observed. Surprisingly, there was a significantly greater presence of indirect verbal aggressiveness in younger children. With respect to temperament, a higher level of negative emotivity was significantly linked to a greater degree of aggressive behaviors in some of the episodes. In conclusion, this paper confirms gender differences in the type of aggressive behavior children display even in the absence of any immediate social interaction, which might itself trigger aggression.

[source] Pore-scale simulations of unsteady flow and heat transfer in tubular fixed bedsAICHE JOURNAL, Issue 4 2009P. Magnico Abstract Small tube-to-particle-diameter ratio induces a radial heterogeneity in tubular fixed beds on the particle scale. In this complex topology, theoretical models fail to predict wall-to-fluid heat transfer. In order to be more realistic, a deterministic Bennett method is first used to synthesize two packings with a tube-to-sphere-diameter ratio of 5.96 and 7.8, containing 236 and 620 spheres, respectively. In a second step, unsteady velocity and temperature fields are computed by CFD. In the range of Reynolds number lying between 80 and 160, hydrodynamic results are validated with experimental data. The thermal disequilibrium in the near-wall region is described in detail. Several pseudo-homogeneous models are compared to the numerical simulations. The radial and axial profiles of temperature show a clear agreement with the model of Schlünder's research group and the model of Martin and Nilles. © 2009 American Institute of Chemical Engineers AIChE J, 2009 [source] Feinberg and Martin on Human RightsJOURNAL OF SOCIAL PHILOSOPHY, Issue 2 2003Derrick Darby First page of article [source] The Validity of DSM-IV Alcohol Dependence: What Do We Know and What Do We Need to Know?ALCOHOLISM, Issue 2 2003Deborah S. Hasin This article presents the proceedings of a symposium at the 2002 RSA Meeting in San Francisco, California. Deborah S. Hasin organized the symposium and co-chaired it with Marc Schuckit. The purpose of the symposium was to provide an overview of what is known about the validity of DSM-IV and ICD-10 alcohol dependence and abuse, with a focus on work done since 1994. Presentations included: (1) Validity of DSM-III-R alcohol dependence in adolescents, by Christopher S. Martin; (2) Reliability and validity of DSM and ICD formulations of alcohol use disorders: findings from epidemiology, by Bridget F. Grant; (3) Validity and reliability of the alcohol-dependence phenotype in the context of genetic studies, by Kathleen K. Bucholz; and (4) DSM-IV and beyond: uniting the clinical utility of categories with the precision of dimensions, by John E. Helzer. The findings supported the validity of DSM-IV alcohol dependence across numerous study designs and samples, suggested some value in a dimensional dependence measure, and raised questions about the validity of the diagnosis of alcohol abuse as currently defined. Marc Schuckit, as discussant for the symposium, placed the issues in perspective for the upcoming DSM-V.

Fleas are significant ectoparasites of small animals. They can be a severe irritant to animals and serve as a vector for a number of infectious diseases. In this article, we discuss the pharmacological characteristics of four insect nicotinic acetylcholine receptor (nAChR) agonists used as flea adulticides in dogs and cats, which include three neonicotinoids (imidacloprid, nitenpyram, and dinotefuran) and a macrocyclic lactone (spinosad). Insect nAChR agonists are one of the most important classes of insecticides, which are used to control sucking insects on both plants and animals. These novel compounds provide a new approach for practitioners to safely and effectively eliminate adult fleas. [source] Phylogeny of Thalassinidea (Crustacea, Decapoda) inferred from three rDNA sequences: implications for morphological evolution and superfamily classificationJOURNAL OF ZOOLOGICAL SYSTEMATICS AND EVOLUTIONARY RESEARCH, Issue 3 2008L. M. Tsang Abstract The infraorder Thalassinidea is a group of cryptic marine burrowing decapods of which the higher taxonomy is often contentious. The present analysis attempts to reconstruct phylogenetic relationship among 12 of the 13 currently recognized families using partial nuclear 18S, 28S rDNA and mitochondrial 16S rDNA sequences. The infraorder is divided into two distinct clades, with the first clade consisting of Thalassinidae, Laomediidae, Axianassidae and Upogebiidae, and the second clade including Axiidae, Calocarididae, Eiconaxiidae, Callianassidae, Ctenochelidae, Micheleidae, Strahlaxiidae and Callianideidae. Within the first clade, the Upogebiidae is the basal family. The Axianassidae shows low affinity to other laomediid genera indicating that it is a valid family. The interfamilial relationships are less well resolved in the second clade. The Axiidae is paraphyletic with respect to Calocarididae and Eiconaxiidae. Thus, the status of these two latter families is not supported if the currently defined Axiidae is maintained. All three families appear to be basal in the thalassinidean clade. The Micheleidae is closely related to the Callianideidae and they form a sister group to the Strahlaxiidae. The monophyletic Callianassidae aligns with the Micheleidae + Callianideidae + Strahlaxiidae clade. The relationship among the Axiidae + Calocarididae + Eiconaxiidae clade, Callianassidae + Micheleidae + Callianideidae + Strahlaxiidae clade and the Ctenochelidae cannot be resolved which might be due to a rapid radiation of the three lineages. Our results do not support the generally used classification scheme of Thalassinidea and suggest that the infraorder might be divided into two superfamilies instead of three as suggested based on larval morphology, second pereiopod morphology in adults and gastric mill structure. The two superfamilies are Thalassinoidea (i.e. Thalassinidae, Laomediidae, Upogebiidae and Axianassidae) and Callianassoidea (i.e. Axioidea + Callianassoidea, as defined in Martin and Davis (2001) but excluding Laomediidae and Upogebiidae). It also appears that gill-cleaning adaptations are important in thalassinidean evolution while the presence of linea thalassinica is a result of parallel evolution. Résumé L'infraordre des Thalassinidea est un groupe de décapodes marins fouisseurs cryptiques dont la taxonomie au niveau supérieur est souvent controversée. Cette analyse tente de reconstruire les relations phylogénétiques entre 12 familles sur les 13 actuellement reconnues en utilisant les séquences partielles de rDNA nucléaire 18S, 28S et de rDNA mitochondrial 16S. L'infraordre est divisé en deux clades distincts, le premier comprenant les Thalassinidae, Laomediidae, Axianassidae et Upogebiidae, et le deuxième comprenant les Axiidae, Calocarididae, Eiconaxiidae, Callianassidae, Ctenochelidae, Micheleidae, Strahlaxiidae et Callianideidae. Dans le premier clade, les Upogebiidae est la famille basale. Les Axianassidae montre peu d'affinité avec les autres genres de laomedidés, ce qui indique que la famille est valide. Les relations interfamiliales sont moins bien résolues dans le second clade. La famille des Axiidae est paraphylétique par rapport aux Calocarididae et Eiconaxiidae. Ainsi le statut de ces deux dernières familles n'est pas supporté si la famille des Axiidae est maintenue dans sa définition actuelle. Toutes les trois familles apparaissent basales dans le clade thalassinidéen. La famille des Micheleidae est très proche des Callianideidae et elles forment un groupe frère des Strahlaxiidae. La famille monophylétique des Callianassidae s'aligne avec le clade Micheleidae + Callianideidae + Strahlaxiidae. La relation entre le clade Axiidae + Calocarididae + Eiconaxiidae, le clade des Callianassidae + Micheleidae + Callianideidae + Strahlaxiidae et la famille des Ctenochelidae ne peut être résolue, ce qui pourrait être dûà une radiation rapide des trois lignées Nos résultats ne supportent pas le schéma de classification généralement utilisé pour les Thalassinidea et suggèrent que l'infraordre pourrait être divisé en deux superfamilles au lieu de trois comme suggéré sur la base de la morphologie larvaire, de la morphologie du deuxième péréiopode de l'adulte et de la structure du moulin gastrique. Les deux superfamilles sont: les Thalassinoidea (c'est-à-dire Thalassinidae, Laomediidae, Upogebiidae et Axianassidae) et Callianassoidea (c'est-à-dire Axioidea + Callianassoidea, comme définis dans Martin et Davis 2001 mais excluant les Laomediidae et les Upogebiidae). Il apparaît aussi que les adaptations pour le nettoyage des branchies sont importantes dans l'évolution thalassinidéenne alors que la présence de la linea thalassinica est le résultat d'une évolution parallèle.

Nash ABSTRACT, Paul Sidney Martin excavated archaeological sites in southwestern Colorado for the State Historical Society of Colorado and the Field Museum of Natural History between 1927 and 1938, although he began working for museums in 1925. His work in three realms,research, exhibition and outreach, and collections,helped redefine the role of the museum anthropologist at a time when archaeological research, particularly that based in museums, was in transition away from the search for exhibition-quality objects and toward research-driven expeditions. With data gleaned from relevant archives, in this article I present previously unpublished details of Martin's work to suggest that Martin leaves behind a conflicted legacy from an important era in the development of North American archaeology.

Colonial Women Writing WarNEW ZEALAND GEOGRAPHER, Issue 1 2000KAREN M. MORIN ABSTRACT This paper examines the wartime literature of Sarah Selwyn, Mary Ann Martin, and Caroline Abraham, all wives of prominent church and government men in colonial Aotearoa/New Zealand. Along with their husbands these women became leading participants in the "pamphlet war" surrounding the justice and legality of the colonial government's survey and confiscation of M,ori land at Taranaki, c. 1850,1860. I analyze the socio-spatial frameworks of these colonial women, linking them with their protest narratives of the Taranaki confiscations and ensuing war. The anti-colonial position articulated by these women must be viewed within the context of ideological constraints on women's participation in public life, but also within the context of expanded social and spatial boundaries of such high-placed colonials, the gendered space of the episcopal residences during wartime, the women's networks of communication, and their material and discursive links to public arguments taking place in England over colonial conflicts.

The new economic geography lies well within economics proper: it is an offspring of international trade theory, with models characterized by increasing returns, factor mobility, and transportation costs. The models explain the distribution of industry in terms of the opposition of an agglomerating force, the interaction of transportation costs and increasing returns to scale, with a dispersing force, commonly the interaction of transportation costs and a partially fixed input or output market. Some authors outside the new economic geography (e.g., Martin 1999) have criticized it as simplistic, irrelevant, or passé. They claim it employs overly abstract analysis, prioritizes mathematical technique over realistic explanation, and is reminiscent of the much earlier works of Gunnar Myrdal and François Perroux,in comparison to which, however, it falls short. This paper investigates the similarities and differences between the new economic geography and the work of Myrdal and Perroux, who in the previous special issue of this journal were ranked by Zafirovsky (1999, pp. 596, 598) as among the leading twentieth century economic sociologists. I examine how the techniques of analysis and intuitive explanations of agglomeration compare between these economic sociologists and the new economic geographers. The paper highlights what has been gained and what has been lost by the new economic geographers, who generally eschew interdisciplinary study. [source] |
