U–Pb dates from zircons indicate that plutonic events occurred during the Paleozoic in the Omineca Crystalline Belt in southeastern British Columbia. In the Kootenay Arc, granitoid cobbles in conglomerate of the Carboniferous Milford Group were derived from quartz monzonite and diorite plutons of probable Ordovician age. Near Little Shuswap Lake, gneissic granitoid units have yielded Cambro-Ordovician ages. At least one episode of deformation affected country rocks of unknown age before intrusion. In the Monashee Complex south of Thor–Odin Nappe in South Fosthall Creek, lineated quartz monzonite is of probable Ordovician age. Comparison of fabrics suggests that at least one episode of metamorphism and deformation occurred prior to intrusion. No clear relationship between the cobbles and these plutons can be demonstrated because major faults lie between them, but substantial revision to accepted models of Paleozoic paleogeography of this region will have to be made. In the Clachnaeudainn tectonic slice east of the Monashee Complex, granitic gneiss is of Paleozoic, possibly Siluro-Devonian, age. This pluton appears to be involved in all phases of deformation that affected its country rocks. Near Quesnel Lake, parts of a composite gneissic granitoid pluton appear to be of Devonian or earliest Carboniferous age.

This article presents our attempt to move beyond both developmental and Reggio Emilia guidelines for listening. We situate our efforts within our wounded colonial context—what is now called Victoria, British Columbia. Our effort is to begin to consider listening within unequal spaces of power, and to wonder what ethics such arrangements might require. In our engagements with clay and stones with the children, we noticed the sound the stones and clay made. In this article, we work with several stories of our investigations into sound, which have helped us to think about the complexities of listening in childcare spaces.

In 2011, British Columbia (BC) First Nations came together to speak with one voice and by consensus made the largest self-determining decision made in this country: to take control over their own health and wellness. Guided by First Nations perspectives, values, and principles, the First Nations Health Authority works alongside the First Nations Health Directors Association and the First Nations Health Council to advance a shared vision of “healthy, self-determining, and vibrant BC First Nations children, families, and communities.” Strong leadership, rooted in the knowledge and teachings that have sustained BC First Nations for thousands of years, is integral to achievement of the vision. This article reflects on Indigenous approaches to health and wellness leadership in the BC context, drawing from traditional teachings shared by BC First Nations Elders and knowledge keepers in four areas: upholding governance and self-determination, “change starts with me,” building a leadership team, and reconciliation and partnership.

Alkali Feldspars

Adamant pluton is a zoned body of igneous origin, with a core of pyroxene monzonite transitional outward to hornblende quartz monzonite and biotite-hornblende granodiorite. On chemical and textural evidence, the lithologic zoning resulted from reaction with introduced water and oxygen during regional metamorphism to upper amphibolite facies. Feldspars in the monzonite are orthoclase and andesine of intermediate structural state. During transformation of the pluton, systematic changes in the feldspars comprised: (1) ordering of alkali feldspars toward intermediate microcline, with increase of 2V, decrease of Na and Ca content, and appearance of grid twins; (2) ordering and increase in Na content of plagioclase. The most ordered feldspars, with highest Na distribution coefficient, are found in peripheral granodiorite and in pegmatite cutting the quartz monzonite. The feldspar data support the model proposed for the evolution of the pluton, indicating approach to equilibrium in the peripheral rocks at lower temperatures than that attendant to the formation of the core.

Monashee Complex

Microstructural and petrofabric analyses of mylonites from the Monashee Décollement demonstrate that the hanging wall was displaced eastward over the footwall. Microstructural kinematic indicators include shear-band foliation, asymmetric strain shadows, and S–C fabrics. Quartz c axes locally exhibit asymmetric fabrics that are consistent with the microstructural evidence for sense of shear. The kinematic evidence is reliable because multiple criteria coexist within individual specimens.Metamorphic assemblages from footwall Monashee Complex pelites at the Revelstoke damsite indicate that the peak metamorphic assemblage was sillimanite–K-feldspar–biotite–almandine–quartz ± plagioclase. Biotite–garnet geothermometry and garnet–plagioclase–sillimanite–quartz geobarometry set broad constraints on metamorphic temperatures but closer constraints on pressures, near 650 °C and 630 MPa.Comparison of these data with Late Cretaceous hornblende cooling ages from the same locality indicates that the metamorphism is at least as old as Late Cretaceous. Complex microstructures relating to repeated mylonitization and annealing render difficult the correlation of metamorphic conditions with mylonitic fabrics. Early mylonitic textures predate the metamorphic equilibration and thus are pre-Late Cretaceous in age. Postmetamorphic mylonites are well preserved, but their ages are poorly constrained. The present interpretation favours a Late Cretaceous to Paleocene age relating to compressional tectonics. However, an Early Eocene age relating to extensional shearing cannot be excluded.

Myxosoma cerebralis (Hofer, 1903) was not observed in 973 wild and 4496 cultured salmonids examined from collections made in widely separated localities in British Columbia from 1968 to 1980. Species investigated were Salmo clarki (180), S. gairdneri (3688), S. trutta (16), Salvelinus fontinalis (185), S. malma (300), Oncorhynchus gorbuscha (109), O. keta (17), O. kisutch (785), O. nerka (126), and O. tshawytscha (63). Previous reports notwithstanding, in the absence of corroborative evidence British Columbia (Canada) should not be accepted as a center of M. cerebralis infection.Key words: Myxosoma cerebralis, salmonids, British Columbia, whirling disease

ABSTRACTBackground:Inadequate hospital stocking and the unavailability of essential antidotes is a worldwide problem with potentially disastrous repercussions for poisoned patients. Research indicates minimal progress has been made in the resolution of this issue in both urban and rural hospitals. In response to this issue the British Columbia Drug and Poison Information Centre developed provincial antidote stocking guidelines in 2003. We sought to determine the compliance with antidote stocking in BC hospitals and any factors associated with inadequate supply.Methods:A 2-part survey, consisting of hospital demographics and antidote stocking information, was distributed in 2005 to all acute care hospital pharmacy directors in BC. The 32 antidotes examined (21 deemed essential) and the definitions of adequacy were based on the 2003 BC guidelines. Availability was reported as number of antidotes stocked per hospital and proportion of hospitals stocking each antidote. For secondary purposes, we assessed factors potentially associated with inadequate stocking.Results:Surveys were completed for all 79 (100%) hospitals. A mean of 15.6 ± 4.9 antidotes were adequately stocked per hospital. Over 90% of hospitals had adequate stocks ofN-acetylcysteine, activated charcoal, naloxone, calcium salts, flumazenil and vitamin K; 71%–90% had adequate dextrose 50% in water (D50W), ethyl alcohol or fomepizole, polyethylene glycol electrolyte solution, protamine sulfate, and cyanide antidotes; 51%–70% had adequate folic acid, glucagon, methylene blue, atropine, pralidoxime, leucovorin, pyridoxine, and deferoxamine; and <50% had adequate isoproterenol and digoxin immune Fab. Only 7 (8.9%) hospitals sufficiently stocked all 21 essential antidotes. Factors predicting poor stocking included small hospital size (p < 0.0001), isolation (p = 0.01) and rural location (p < 0.0001).Conclusion:Although antidote stocking has improved since the implementation of the 2003 guidelines, essential antidotes are absent in many BC hospitals. Future research should focus on determining the reasons for this situation and the effects of corrective interventions.

The Upper Jurassic Topley Intrusions intrude rocks of the tectonically stable Interior Plateau in central British Columbia. A stable primary remanent magnetization of both normal and reversed polarity was isolated after a.f. demagnetization in 19 of 22 sites (109 cores; 208 specimens) representing several of the plutonic units present in this sialic complex of quartz monzonite affinity near Endako, B.C. The unit mean remanence directions support some petrological correlations suggested by Carr, Bright, and White et al., but do not support others. The pole position derived from 13 sites representing 6 plutonic units with a K–Ar radiomelric age of 139 ± 4 m.y. (White et al.) is 128.6 °E, 70.0 °N(δm = 14.4°; δp = 11.4°). This position indicates a smooth polar wander path during the Jurassic between the well defined Upper Triassic and Lower Cretaceous pole positions. It also indicates that the northern Interior Plateau has not been tectonically rotated or translated since emplacement relative to the stable North American craton.
