Sex determination with the head of the radius

Analysis of a sample of 1108 radii corresponding to 567 black and white North Americans in the Terry Collection at the Smithsonian Institution demonstrates that the diameter of the radial head is an accurate sex discriminator for human remains. A simple "radial-head method" of sex determination consists of measuring the maximum and minimum diameters of the head and comparing such measurements with the test cutoff points. The subject is female when the maximum radial head diameter (either left or right) is less than or equal to 21 mm, and male when the maximum diameter (either left or right) is greater than or equal to 24 mm. The same decisions apply to the minimum diameters of 20 mm or less and 23 mm or more, respectively. When the maximum diameter is 23 mm or the minimum is 22 mm, the subject is more likely male; when the maximum diameter is 22 mm or the minimum is 21 mm, the subject is more likely female. The sample frequency of any one of these latter diameters is never more than 16%. Cross-validation of the method with a sample of 50 pairs of radii of the Terry Collection, different from the original specimens, resulted in 92% sexing accuracy when using the left radius singly, 94% accuracy when using the right radius singly, and 96% accuracy when using both radii jointly.     

Identification of a red "fiber": chironomid larvae

During preliminary examination of the body of a homicide victim, a peculiar red "fiber" was noticed and recovered. Initially believing this to be a carpet fiber, the item was subjected to fiber analysis. It was found to be a short coiled particle not like any known natural or synthetic fabric fiber. Subsequent examinations determined this "fiber" to be the larva of a common freshwater midge (Diptera; Chironomidae). Chironomid larvae have been observed on other bodies recovered from freshwater environments. Entomological studies of this organism have led to the conclusion that the presence of chironomid larvae indicates submersion of the body.     

Realization of an adaptive method of simulating the process of temperature change of a cadaver on a microcomputer

Programme based on mathematical model of the process of dead body temperature changing was developed for estimation of postmortem interval. Automatic retrieval of problem solution was performed on programmable microcalculators of "Electronica MK-61" type using adaptive approach. Diagnostical accuracy in case of dead body being preserved in permanent cooling conditions is +/- 3%.     

Do legislators' votes reflect constituency preference? A simple way to evaluate the Senate

U.S. senators frequently vote against the preference of their constituency, assuming that such a preference exists. Both of a state's senators represent the same constituency. Whenever they split their votes, one or the other is necessarily going against the constituency preference. For the sample of defense-related votes analyzed above, misrepresentation — either observable vote splitting or unobservable vote matches that go against the constituency preference — occurred at least 37 percent of the time, at least 46 percent on one vote. Although party differences accounted for more than two-thirds of the vote splitting, a substantial number of splits remained. Besides, a party difference for a state's senatorial pair is itself problematical.The method employed here can be applied easily to any data whatever on senatorial voting. Its application will show that, quite often, many senators depart from constituency preference. This finding refutes the hypothesis, popular in certain circles, that ours is a more or less perfect political market with little or no scope for ideologically driven voting by legislators.     

A precise method for evaluating election schemes

A previously published paper evaluated election schemes under a wide variety of election circumstances. This paper improves upon the previous work by refining the measures used to rate the election schemes and increasing the statistical significance of those ratings. With these modifications, we can now draw some new conclusions:

1. In general circumstances, the Borda System outperforms the Copeland System which outperforms Approval which outperforms Majority Rule.
2. The Maximin Rule — strongly supported by Rawls's — turns out to be a reasonable election rule if the number of election alternatives is large relative to the number of voters.
3. With two exceptions, all our election systems performed quite well given a society with highly correlated utilities.
4. Given a polarized society, a serial dictatorship was better than every other election system except Borda.

Perhaps even more importantly, we now have the possibility of conducting some cost/benefit analyses of different proposals for electoral changes.     

Community midwifery and state measures: the new midwifery in British Columbia

The New Midwifery, a form of community midwifery rooted in home birth and intensive prenatal and postnatal care, has attracted great controversy since its appearance in British Columbia in the early 1970s. On the one hand, this form of community midwifery has endured despite legal prohibition. Midwives derive an income from their practices, obtain necessary supplies and equipment, and are active in lobbying for recognition through the State. On the other hand, community midwifery is marginalized and illegal. Out-of-hospital births comprise less than one percent of births in British Columbia (and nationwide). Community midwives are excluded from the provincal Medical Services Plan and they lack hospital privileges if their clients are transferred to hospital. Community midwives are more likely than medical personnel to be tried for criminal negligence causing death and subject to prosecution under theMedical Practitioners Act of practicing medicine without a license.Community midwifery illustrates the structural limits placed on female birth attendants working outside the norm of professionally accredited, hospital situated childbirth. It is concluded that State measures in Canada structure power relations in a dialectical fashion. This includes measures to consolidate the monopoly status of the medical profession and the nursing profession, while temporizing about demands for independent midwifery practice. State powers are however relatively autonomous of dominant economic groups such as the Medical profession. Not all prosecutions of community midwives are successful, and contradictions in State policies surrounding monopolistic powers and civil liberties, and gender relations are evident.An earlier version of this paper was presented at the Canadian Sociology and Anthropology Association Meetings, University of Manitoba, June 1986.

Deaths allegedly caused by the use of "choke holds" (shime-waza)

Shime-waza or the "choke hold", when properly applied, should not cause death; therefore, its primary purpose should be to subdue violent suspects. When properly applied, the choke hold causes unconsciousness in 10 to 20 s. No fatalities as a result of shime-waza have been reported in the sport of judo since its inception in 1882. Among the methods of "control holds" taught to law enforcement officers is the choke hold similar or identical to shime-waza used in judo. Using the choke hold, officers may afford themselves maximum safety while subjecting the suspect to a minimum possibility of injury. The author has reviewed 14 fatalities with autopsy findings where death was allegedly caused by the use of choke holds.
