Between the waves: currents in contemporary feminist thought
No full textWith a continuing focus on liberal feminism, Marxist feminism and essentialism, one would be forgiven for
thinking that feminist theory is unable to break free from the ‘second wave’. This is not the case. This article reviews three books which take on these feminist issues and offer new readings on the questions at the heart of feminism. Each provides clear links to feminism of the past but also connects to present debate and makes
suggestions for future directions for feminism. There is plenty of literature which bemoans the end of feminism and some which triumphantly hails our era as post-feminist: no longer in need of feminist theory. Contrary to such claims, each book tackles the problem of women’s oppression from a different perspective, each presents different solutions and in so doing they demonstrate that feminism is alive and well
CONJOINT ANALYSIS OF DEER HUNTING
No full textThis paper develops a logit-based conjoint analysis of willingness to pay for individual attributes of deer-hunting trips. Since deer-hunting success is uncertain, willingness to pay for enhanced likelihood of bagging a deer, rather than for certain success, is evaluated. Implicit costs of recreational travel time are also evaluated from hypothetical trade-offs between travel time and trip expenditures. The valuation of travel time derived here appears to reflect more the opportunity cost of foregone hunting than the opportunity cost of foregone work. This implies that travel-cost analyses of recreational demand, which impute costs of recreational travel solely from wage data, can yield biased valuations of recreational amenities.Resource /Energy Economics and Policy,
The Scots abroad: migration and mission
No full textKenneth Ross’s essay begins with an overview of the migration of the Scots round the world in the age of colonialism. He then examines this more closely, exploring the relationship between migration and missions in the diaspora church. Beginning with mission-migrant relations in Malawi, Ross then points to more general, more deeply-rooted tensions arising in the Scottish diaspora, reflected in the conflicting interests of expatriate churches and mission agencies.Publisher PD

Hydrogeology, geopressures and hydrocarbon occurrences, Beaufort-Mackenzie Basin
No full textAbout 97 400km of the coastal and offshore areas of the Beaufort-Mackenzie Basin were studied in the region from 68° to 71°N, and 130° to 137°30′W. Salinity of formation waters ranges up to 46 000mg/l at depths of 4km and shows evidence of extensive flushing by meteoric waters. Statistical multi-response permutation procedures demonstrate that, despite this deep flushing, it is also possible to distinguish formation waters from geopressure zones that had their composition modified by the membrane effects of shales. The top of the main geopressure zone lies at depths of about 2km beneath Richards island and increases in depth basinward to ~5km/ It is suggested that the main geopressure zone was already in existence sometime during the middle of the Tertiary, with its top lying at about 2km depth. Basinal uplift and erosion in the period from 6 to 5Ma was associated with extensive influx of meteoric water, which biodegraded the earlier formed hydrocrabons. Pliocene to Recent sediments of the Iperk sequence were deposited during a major basinal downwarp, with up to 3.5km being deposited far offshore. The geothermal regime has been able to adjust to this downwarping but the pre-Pliocene geopressure zone has not, and as a result still lies about 2km below the base of the Iperk sequence. Hydrocarbons, in the Mackenzie Bay and Kugmallit sequences (Miocene and Oligocene, respectively) occur above the main geopressure zone. -from Author
Inorganic Polymers (Geopolymers) as Potential Bioactive Materials
No full textThe primary aim of this project was to synthesise potassium activated geopolymer composites with bioactivity, and this was realised by adding
10wt% of calcium hydroxide, nano-structured calcium silicate or calcium phosphate to the geopolymer matrix. The synthesised samples were cured at 40'C then heated to 550'C and 600'C to reduce their alkalinity. Tensile strength was measured by diametral compression. The effect of exposure to simulated body fluid (SBF) was determined by x-ray diffractometry (XRD), 27Al, 29Si and 43Ca nuclear magnetic resonance spectroscopy with magic angle spinning (MAS NMR), pH measurements, inductively coupled plasma (ICP), scanning electron microscopy (SEM) and energy dispersive x-ray analysis (EDS).
XRD, 27Al and 29Si MAS NMR confirmed that all the samples retained their structural characteristics of a true aluminosilicate geopolymer, even after heating and exposure to SBF. EDS examination of the calcium-containing
geopolymer composites showed that the calcium distribution was generally homogeneous. Exposure of the geopolymer composites to SBF at body temperature, was used to simulate the behaviour of the geopolymer composites in blood plasma. XRD and SEM/ EDS analysis showed that the geopolymers containing calcium hydroxide and calcium silicate formed hydroxyl apatite (HA) and carbonate hydroxyl apatite (HCA) after their exposure to SBF, indicating a degree of bioactivity. The absorption of calcium and phosphorus from the SBF and the observation of nano crystals rich in these elements provide some evidence of bioactive phases in the composite containing calcium phosphate and the reference geopolymer. The reference and the calcium phosphate geopolymer (both heated to 600XC) produced the lowest pH (ca.8) in the SBF. ICP analysis of the SBF after exposure shows that most of the aluminium remains in the geopolymer structure. The greatest release of aluminium
(< 2.7 ppm after 168 hours) was found for the calcium hydroxide geopolymer (heated to 600'C). Diametral compression testing showed that the strength of the calcium phosphate-containing geopolymer heated to 550'C (4.17 MPa) is comparable with that of Bioglass(R)(5.56 MPa), currently used as a bio-material. Although none of the composites are ideal in all respects, they show
sufficient promise to suggest that with further refinement, geopolymer materials may well be become candidates as bioactive ceramics

In situ 64Cu Doppler-broadening positron-annihilation methods for elevated temperature study of defect formation in metals formation in metals
No full textDoppler-broadening positron-annihilation-spectroscopy experiment that utilizes an in situ Cu-64 source for the study of Cu and Cu-containing materials is described. This technique is particularly useful for the investigation of defect structure at elevated temperatures, and the present instrumentation provides reliable results up to about 1000 degrees C. The method described is applicable to Cu-containing samples with as little as about 0.1 at.% Cu. Results from measurements on a single crystal of elemental Cu are compared with literature results obtained using other positron-annihilation methods and electrical-resistivity studies.PT: J; CR: BERGER AS, 1979, J PHYS F MET PHYS, V9, P1023 CAMPBELL JL, 1977, APPL PHYS, V13, P365 DANNEFAER S, 1975, NUCL INSTRUM METHODS, V131, P119 DUNLAP RA, 1988, CAN J PHYS, V66, P476 DUNLAP RA, 1988, EXPT PHYSICS MODERN FLUSS MJ, 1980, J PHYS F MET PHYS, V10, P1763 FUKUSHIMA H, 1976, J PHYS F MET PHYS, V6, P677 JACKMAN TE, 1974, APPL PHYS, V5, P259 LAWTHER DW, 1990, J PHYS-CONDENS MAT, V2, P6239 LAWTHER DW, 1993, J NON-CRYST SOLIDS, V153, P611 LAWTHER DW, 1993, KEY ENG MATER, V81, P95 LAWTHER DW, 1994, PHYS REV B, V49, P3183 LICHTENBERGER PC, 1975, THESIS U WATERLOO WA MACKENZIE IK, 1967, PHYS REV LETT, V19, P946 MACKENZIE IK, 1970, PHYS LETT A, V33, P279 MACKENZIE IK, 1980, NUOVO CIMENTO B, V58, P162 MACKENZIE IK, 1983, POSITRON SOLID STATE, P196 MCKEE BTA, 1967, THESIS DALHOUSIE U H RICEEVANS P, 1976, J PHYS F MET PHYS, V6, P1079 RYAN DE, 1987, ANAL CHIM ACTA, V200, P89 SCHAEFER HE, 1987, VACANCIES INTERSTIT, P117 SCHULTZ PJ, 1981, CAN J PHYS, V59, P325 SCHULTZ PJ, 1988, REV MOD PHYS, V60, P701 SEGERS D, 1988, PHYS LETT A, V133, P455 SIEGEL RW, 1980, ANNU REV MATER SCI, V10, P393; NR: 25; TC: 0; J9: CAN J PHYS; PG: 7; GA: RD935Source type: Electronic(1
