Diamond Jenness (1886-1969)

Canada's most distinguished anthropologist, Dr. Diamond Jenness, formerly Chief of the Division of Anthropology, National Museums of Canada, and Honorary Associate of the Arctic Institute of North America, died peacefully at his home in the Gatineau Hills near Ottawa on 29 November, 1969. He was one of that rapidly-vanishing, virtually extinct kind - the all round anthropologist, who, working seriously, turned out first-class publications in all four major branches of the discipline: ethnology, linguistics, archaeology, and physical anthropology. One must also add a fifth: applied anthropology, a fitting designation for the series of monographs on Eskimo administration in Alaska, Canada, and Greenland which he wrote after his retirement and which were published by the Arctic Institute of North America. ... [In response to an invitation to join Stefansson Arctic Expedition and study Eskimos for three years, Jenness found himself a member of the Southern Party with an assignment to study the Copper Eskimos around Coronation Gulf. These plans were interrupted due to the presence of sea ice.] On 30 September, Stefansson, with his secretary Burt McConnell, Jenness, two Eskimos, and the expedition's photographer G.H. Wilkins (later Sir Hubert Wilkins), left the Karluk near the mouth of the Colville River to hunt caribou and lay in a supply of fresh meat when it had become apparent that the ship, immobilized in the ice, could proceed no further. With two sleds, twelve dogs and food for twelve days the party set out for the mainland, but they never saw the Karluk again, for a week or so later the unfortunate vessel began her final drift westward. This was the inauspicious beginning of Jenness' arctic career. Few young anthropologists have faced such difficulties in beginning field-work in a new and unfamiliar area; yet none, surely, has emerged from the test with a more brilliant record of work accomplished. ... Jenness' first winter's field-work on the Arctic coast of Alaska led to [an] impressive list of publications ... conducted under conditions that many an ethnographer would have found intolerable. ... Scarcely a hint of these personal experiences of his first winter in the Arctic will be found in Jenness' anthropological writings. They were reserved for his retrospective volume Dawn in Arctic Alaska (1957) which he wrote while on a Gugenheim scholarship in 1954, some years after his retirement. ... Jenness' first year in the Arctic ended in July 1914 when the Expedition's schooners left Camden Bay and sailed eastward to Dolphin and Union Strait where he was to meet with another though very different, Eskimo people named by Stefansson the Copper Eskimos, most of whom, before Stefansson worked among them in 1910-1911, had never seen a white man. ... To obtain a faithful picture of the life of the Copper Eskimos Jenness chose an approach that in those days was not often employed by ethnologists. He entered into their life directly, as one of them. He attached himself to an Eskimo family and became the adopted son of Ikpukhuak, one of the foremost hunters and respected leaders of the Puivlik tribe of southwest Victoria Island, and his wife Higilak (Ice House), who was not only proficient in the ordinary and burdensome duties of an Eskimo wife but was also a shaman in her own right, a talent that saved Jenness from a local murder charge. Jenness lived with these people in their snow houses in winter and skin tents in summer, observing and recording the vastly different modes of life according to season. ... Jenness' researches extended far beyond Coronation Gulf and the arctic coast westward. ... Jenness always disclaimed being an archaeologist, yet he made two discoveries that are fundamental to an understanding of Eskimo prehistory - discovery of the Dorset culture in the eastern Arctic, and of the Old Bering Sea, earliest stage of the maritime pattern of Eskimo culture that later spread from northern Alaska to Canada and Greenland to form the principal basis for modern Eskimo culture. ... And so much more. In 1926, Jenness succeeded Edward Sapir as Chief Anthropologist of the National Museum of Canada. ... He developed the Antiquities Legislation that has been so important for the protection of archaeological resources in the Northwest Territories. ... Between 1962 and 1968 the Arctic Institute of North America published his admirable five volumes on Eskimo administration in Alaska, Canada, and Greenland. These monographs reflect his durable and compassionate concern for Canadian Indians and Eskimos and in them one can find much of the advice that he, for so many decades, provided the Canadian Government. ... [Jenness' accomplishments extend beyond the realm of anthropology and his reputation was both national and international. For his services in the field of anthropology, particularly in connection with the Indian and Eskimo population of Canada, he was appointed a Companion of the Order of Canada.

The P-T-t architecture of a Gondwanan suture: REE, U-Pb and Ti-in-zircon thermometric constraints from the Palghat Cauvery shear system, South India

Understanding the relationship between accessory mineral growth and the evolution of silicate mineral assemblages along the entirety of a P-T-t path is a critical step in developing models for evolving tectonic systems. Here we combine U–Pb age data (for zircon and monazite), rare earth element (REE) data and compositionally specific phase diagrams (P-T pseudosections) for the rocks of the Palghat Cauvery shear system (PCSS), Southern Indian order to constrain the periodicity of heating/cooling and burial/exhumation events during the Ediacaran/Cambrian amalgamation of Gondwana. HREE data from zircon are consistent with zircon grow that 672–724 °C during the breakdown of garnet in the kyanite stability field at 535.0 ± 4.9 Ma. This represents a cooling that punctuates the P-T-t path. Subsequent monazite growth and symplectite formation occurred at 920 °C and 7.5 kbar, 10 Ma after zircon growth which reflects a period of reheating and decompression related to delamination and the collapse of the East African orogen. The REE chemistry of the monazite is consistent with the system having undergone partial melting prior to monazite growth, thereby altering the bulk rock chemistry. The periodicity of the heating and cooling cycles (10 Ma) from this study is consistent with recently proposed tectonic switching models for the formation of granulite metamorphism in accretionary/collisional tectonic settings. The elevated heat flows required to generate the UHT metamorphism are achievable in the proposed back-arc setting for the PCSS during Gondwana amalgamation.Chris Clark, Alan S. Collins, M.

Great Expectations: Voluntary Sports Clubs and Their Role in Delivering National Policy for English Sport

“The original publication is available at www.springerlink.com”. Copyright International Society for Third-Sector Research and The Johns Hopkins University. DOI: 10.1007/s11266-009-9095-yVoluntary sports clubs (VSCs) account for about a quarter of all volunteering in England. The volunteers work in a mutual aid, self-production, self-consumption system whose main purpose is identifying and nurturing high-level performers. But the new HMG/Sport England strategies leading to London 2012 expects volunteers to make a major contribution to sustaining and extending participation. The study utilized six focus group sessions with a total of 36 officials and members of 36 clubs across the six counties of Eastern England to assess whether and to what extent government policy objectives can be delivered through the voluntary sector. The study focused on the perceptions and attitudes of club members about being expected to serve public policy and the current pressures they and their clubs face. The results lead the authors to question the appropriateness, sensitivity, and feasibility of current sport policy, particularly the emphasis on VSCs as policy implementers.Peer reviewe

Progress in the development of a biopesticide for the structural treatment of grain stores

Chemical insecticides are used to protect stored grain from infestation by stored product insects and mites. In the UK only a limited number of products are available for application and there are concerns about safety, pest resistance and environmental impact of these conventional pesticides. Biological control offers an alternative to the use of chemical insecticides. The potential for biological control of storage pests in the UK using an insect-specific fungus, Beauveria bassiana, to treat the structure of the stores, has previously been established. However, this study also highlighted areas where improvements were needed; specifically to improve the uptake of the fungal conidia by the pests and to improve their germination and penetration into the pests. In addition it was necessary to ensure that potential formulations had a good shelf-life and to develop a mass production method to consistently produce high quality fungal conidia. A four year project has recently been completed examining these  areas in detail. The work has concentrated on two different fungal isolates of B. bassiana, both of which were found from insects in UK grain stores. Optimisation of production methods, formulation and delivery systems has resulted in prototype formulations that exhibit good viability over periods up to one year and that have good efficacy against a range of storage insect pests under conditions that are likely to be found in UK grain stores. Pilot scale trials using three species of stored product beetle have shown that significant levels of control can be achieved. An overview of the key findings is presented. The study has made a significant contribution to the development of a biopesticide as a structural treatment for grain storage areas in the UK.Keywords: Biological control; Beauveria bassiana; Oryzaephilus surinamensis; Structural treatment; Biopesticid

Measurement of ambient aerosol hydration state at Great Smoky Mountains National Park in the southeastern United States

We present results from two field deployments of a unique tandem differential mobility analyzer (TDMA) configuration with two primary capabilities: identifying alternative stable or meta-stable ambient aerosol hydration states associated with hysteresis in aerosol hydration behavior and determining the actual Ambient hydration State (AS-TDMA). This data set is the first to fully classify the ambient hydration state of aerosols despite recognition that hydration state significantly impacts the roles of aerosols in climate, visibility and heterogeneous chemistry. The AS-TDMA was installed at a site in eastern Tennessee on the border of Great Smoky Mountains National Park for projects during the summer of 2006 and winter of 2007–2008. During the summer, 12% of the aerosols sampled in continuous AS-TDMA measurements were found to posses two possible hydration states under ambient conditions. In every case, the more hydrated of the possible states was occupied. The remaining 88% did not posses multiple possible states. In continuous measurements during the winter, 49% of the aerosols sampled possessed two possible ambient hydration states; the remainder possessed only one. Of those aerosols with multiple possible ambient hydration states, 65% occupied the more hydrated state; 35% occupied the less hydrated state. This seasonal contrast is supported by differences in the fine particulate (PM<sub>2.5</sub>) composition and ambient RH as measured during the two study periods. In addition to seasonal summaries, this work includes case studies depicting the variation of hydration state with changing atmospheric conditions

‘They Called Them Communists Then … What D'You Call ‘Em Now? … Insurgents?’. Narratives of British Military Expatriates in the Context of the New Imperialism

This paper addresses the question of the extent to which the colonial past provides material for contemporary actors' understanding of difference. The research from which the paper is drawn involved interview and ethnographic work in three largely white working-class estates in an English provincial city. For this paper we focus on ten life-history interviews with older participants who had spent some time abroad in the British military. Our analysis adopts a postcolonial framework because research participants' current constructions of an amorphous 'Other' (labelled variously as black people, immigrants, foreigners, asylum-seekers or Muslims) reveal strong continuities with discourses deployed by the same individuals to narrate their past experiences of living and working as either military expatriates or spouses during British colonial rule. Theoretically, the paper engages with the work of Frantz Fanon and Edward Said. In keeping with a postcolonial approach, we work against essentialised notions of identity based on 'race' or class. Although we establish continuity between white working-class military emigration in the past and contemporary racialised discourses, we argue that the latter are not class-specific, being as much the creations of the middle-class media and political elite

Rotating Toroidal Branes in Supermembrane and Matrix Theory

In the lightcone frame, where the supermembrane theory and the Matrix model are strikingly similar, the equations of motion admit an elegant complexification in even dimensional spaces. Although the explicit rotational symmetry of the target space is lost, the remaining unitary symmetries apart from providing a simple and unifying description of all known solutions suggest new ones for rotating spherical and toroidal membranes. In this framework the angular momentum is represented by U(1) charges which balance the nonlinear attractive forces of the membrane. We examine in detail a six dimensional rotating toroidal membrane solution which lives in a 3-torus, $T^3$ and admits stable radial modes. In Matrix Theory it corresponds to a toroidal N-$D_{0}$ brane bound state. We demonstrate its existence and discuss its radial stability.Comment: 7 pages, revte

Development of InGaAs/AlGaAsSb Geiger mode avalanche photodiodes

Near-infrared linear mode Al 0.85 Ga 0.15 As 0.56 Sb 0.44 avalanche photodiodes (APDs) exhibit excellent temperature stability, potentially simplifying Geiger mode operation. We have carried out the first experimental evaluation of In 0.53 Ga 0.47 As/Al 0.85 Ga 0.15 As 0.56 Sb 0.44 APDs in Geiger mode. Characterization on multiple devices included temperature-dependent dark current, avalanche multiplication, dark count rate (DCR), afterpulsing, and single photon detection efficiency (SPDE). The temperature coefficient of breakdown voltage extracted from avalanche multiplication data was 13.5 mV⋅K−1 , much lower than InGaAs/InP Geiger mode APDs, reducing changes in operation voltage and offering possible protection from high optical power thermal attack in communication systems. At 200 K, SPDE were 5%–16% with DCR of 1–20 Mc⋅s−1 , comparable to InAlAs and early InP-based Single Photon APDs. The afterpulsing at 200 K was negligible for hold-off time > 50 μ s (reducing to 5 μ s at 250 K). These are similar to the performance of InGaAs/InAlAs and some InGaAs/InP Geiger mode APDs. The data reported in this article is available from the ORDA digital repository (https://doi.org/10.15131/shef.data.24125721)

The Coma cluster magnetic field from Faraday rotation measures

The aim of the present work is to constrain the Coma cluster magnetic field strength, its radial profile and power spectrum by comparing Faraday Rotation Measure (RM) images with numerical simulations of the magnetic field. We have analyzed polarization data for seven radio sources in the Coma cluster field observed with the Very Large Array at 3.6, 6 and 20 cm, and derived Faraday Rotation Measures with kiloparsec scale resolution. Random three dimensional magnetic field models have been simulated for various values of the central intensity B_0 and radial power-law slope eta, where eta indicates how the field scales with respect to the gas density profile. We derive the central magnetic field strength, and radial profile values that best reproduce the RM observations. We find that the magnetic field power spectrum is well represented by a Kolmogorov power spectrum with minimum scale ~ 2 kpc and maximum scale ~ 34 kpc. The central magnetic field strength and radial slope are constrained to be in the range (B_0=3.9 microG; eta=0.4) and (B_0=5.4 microG; eta=0.7) within 1sigma. The best agreement between observations and simulations is achieved for B_0=4.7 microG; eta=0.5. Values of B_0>7 microG and 1.0 are incompatible with RM data at 99 % confidence level.Comment: 23 pages, 21 figures. Higher resolution available at http://www.ira.inaf.it/~bonafede/paper.pdf.
