Chloroquine concentrations in blood and tissues were examined in overdose and non-overdose cases to determine appropriate ranges for interpretation. Twenty-nine literature overdose cases and 8 non-overdose literature cases were compared with this laboratory's findings. The results indicate significant postmortem redistribution of chloroquine. Combining this laboratory's results and the literature results indicates that using a liver concentration of 150 mg/kg as a cutoff between overdose and non-overdose concentrations properly identified 30 of the 34 published cases containing liver chloroquine and 19 of the 20 presented cases. 相似文献

Power Dynamics in an Experimental Game 总被引:1,自引:1,他引:0
We introduce a new experimental method for studying power. Drawing from multiple theoretical perspectives, we conceptualize
power as relational and structural, as well as comprised of different forms through which basic human needs can be met. Thus,
the method we introduce examines how, when faced with a particular need, people use multiple forms of power concurrently and
within a “field of influence,” namely, the other players in a game. This enabled us to examine how one form of power is transformed
into another and how power is transferred from one player to another through interaction, as well as to measure power as behavior,
as the exercise of choice, as potential, and as outcomes. Two experiments using egalitarian start conditions and a survivable
ecology demonstrated that participants used power to gain more power, creating inequality. Being the target of force made
some players unable to “survive” in the local ecology. Theoretical and methodological issues in the study of power are discussed
and the application of our game method to the study of power in other fields is considered. 相似文献

The recent formation of a United Kingdom and Irish working group, the Body Fluids Forum (BFF), highlighted the need to investigate different working practices prior to any inter-laboratory comparison work and identification of best practice. Various dilutions of semen were seeded onto swabs and cloth samples for each BFF member laboratory to test using their standard techniques. The results showed that the detection of acid phosphatase on swabs is best achieved using direct testing rather than on an extract from the swab. Extraction methods for spermatozoa require a balance to be achieved between using a sufficient volume of water to ensure optimal release and minimal volume to ensure a concentrated extract. PSA tests were investigated and found to be more sensitive than Choline. DNA profiles were obtained from samples in which no spermatozoa had been detected during microscopic examination. 相似文献

Peak blood-ethanol concentration and the time of its occurrence after rapid drinking on an empty stomach 总被引:2,自引:0,他引:2
Healthy men, 20 to 60 years old, drank a moderate dose of ethanol in the morning after an overnight fast. They consumed either neat whisky in amounts corresponding to 0.34, 0.51, 0.68, 0.85, or 1.02 g of ethanol per kilogram of body weight or 0.80 g/kg ethanol solvent diluted with orange juice. The peak blood-ethanol concentration (BEC) increased with the dose administered, but the time required to reach the peak was not markedly influenced over the range of doses studied. At a dose of 0.68 g/kg, the peak BEC ranged from 52 to 136 mg/dL (N = 83), and slow absorption (a late-occurring peak) produced a lower peak BEC. The peak BEC was reached between 0 and 45 min for 77% of the subjects (N = 152) and between 0 and 75 min for 97% of them. The time of peaking in venous blood occurred, on average, 10 min later than in capillary (fingertip) blood although the peak BEC was not appreciably different; the mean venous BEC was 97.0 mg/dL (range, 76 to 112 mg/dL), and the mean capillary BEC was 99.6 mg/dL (range, 75 to 123 mg/dL). When subjects drank 0.80 g/kg ethanol diluted with orange juice over 30 min, the average BEC increment between the end of drinking and the peak was 33 mg/dL (range, 0 to 58 mg/dL). The rate of absorption of ethanol was 1.78 mg/dL/min (range, 0.52 to 4.8 mg/dL/min), and the peak BEC occurred within 60 min after the end of drinking in 92% of the trials. The largest BEC increment (mean, 21 mg/dL; range, 0 to 44 mg/dL) was seen during the first 15 min after the drinking period. 相似文献

Reaching for the Philosopher's Stone: Contingent Coordination and the Military's Response to Hurricane Katrina 总被引:1,自引:0,他引:1
When Hurricane Katrina made landfall on the Mississippi Gulf Coast in August 2005, it immediately overwhelmed the abilities of local and state emergency management officials to respond to the ensuing disaster. Although the U.S. Coast Guard and some military units were on scene shortly after the passage of the storm, there seemed to be interminable delays before the military forces began to arrive in numbers to both provide humanitarian relief and secure the affected areas. This article analyzes the response of the National Guard, active-duty military, and Coast Guard forces through the lens of coordination. We find evidence of the successful use of both traditional hierarchical and network-based coordination; we also find support for Donald Kettl's idea of "contingent coordination." 相似文献

Middle‐class families face a range of challenges, including uneven income growth, imposing child care costs, and affordability gaps for higher education. The ideal policies by which policy makers and public administrators can aid the middle class are far from obvious. Policy solutions are likely to mirror our government and population, meaning that they will be decentralized and varied. Achieving a “growing and thriving middle class” requires understanding the composition of the middle class across the country. Benchmarking and measuring the middle‐class condition at the state and substate levels is critical to crafting and adopting effective policy solutions. This Viewpoint essay highlights the Colorado context to demonstrate the measurement of the middle class and tracking of its lived experiences. 相似文献
