Causes of death of patients in an institution for the developmentally disabled

The causes of death of 53 severely to profoundly developmentally disabled patients who died in an intermediate care facility were reviewed. Respiratory disease, predominantly pneumonia and aspiration, accounted for 72% of deaths. Seven patients died of nonrespiratory causes, and in 8 patients, no cause of death could be determined, even after a complete autopsy or investigation. The median age at death was 20 years. The weights of these patients' organs at autopsy were lower than those for normal individuals of the same age. The lifespan of these severely impaired individuals continues to be significantly shortened, even with improved methods of care.     

Detection and use of salivary hemagglutinins for forensic blood grouping

A sensitive method for the detection of anti-A and anti-B hemagglutinins in fresh saliva has been developed. The method utilizes a bromelin treated erythrocyte suspension as indicator cells and includes a simple procedure to concentrate these hemagglutinins. Antiserum directed against immunoglobulin A enhances the hemagglutination assay. We find that these salivary hemagglutinins are present in over 90% of the population and that their titer remains stable over a period of two months. These hemagglutinins can be used to blood type the donor of a saliva sample and can be used in a confirmatory test that complements the commonly used absorption-inhibition test which is used to detect salivary blood group agglutinogens. In preliminary studies we have determined that hemagglutinins can be successfully isolated and analyzed from dried saliva stains.     

PATTERNS OF FORGETTING AND TELESCOPING: An Analysis of LEAA Survey Victimization Data

The research reported in this article sought to estimate the feasibility of measuring patterns of forgetting and forward telescoping in victimization survey data. It was suggested that if these two sources of memory bias could be accurately and reliably measured, victimization survey data could be adjusted to produce improved estimates of both the amount of crime and of changes in the crime rate over time. Examination of the data suggests that the likelihood of developing a general model for correcting mnemonic biases is very low. ll?is conclusion follows from: (I) evidence indicating differential victimization survey recall across reported and unreported crime events; (2) the apparent dissimilarities of telescoping/forgetting patterns across samples and seasons; and (3) the lack of a stable comparison estimate of the “true” distribution of incidents with which to calibrate a correction model.     

POVERTY, URBANIZATION, AND CRIME

In an effort to evaluate the situational determinants of crime, principal components analysis was used to reduce 59 demographic and socioeconomic characteristics of 840 American cities to six independent factors: affluence, stage in life cycle, economic specialization, expenditures policy, poverty, and urbanization. When regressed upon crime rates two of these six factors, urbanization and poverty, were found to be the more important criminogenic forces. The exception to this generalization was the South, where stage in life cycle was more important than poverty in explaining crime. One reason for this exception may be that the South, though having a lower standard of living than other regions of the country, does not have the “culture of poverty” usually associated with lower income. Contrary to the assumption upon which most ecology of crime studies are based, larger cities (over 100,000 in population) are not representative of all cities. Greater association between socioeconomic variables and crime was found in larger than in smaller cities.     

Structure and Process in Consociationalism and Federalism

It is relatively easy to characterize the institutional structureof a country as consociational or federal. The task is muchmore difficult if we turn from structure to the decision process.Within a given structure, there may be a great deal of variationwith regard to the decision process. Data for such variationare given for the decision process in Switzerland for whichthe following four types are distinguished: (1) consociationaland federal, (2) consociational and unitary, (3) competitiveand federal, and (4) competitive and unitary. Difficulties arediscussed in aggregating from such a variation to a measurefor the prevailing decision process in a country as a whole.It is suggested that the problem be disaggregated and that decisionprocesses be compared for particular issues. This can be doneboth across and within countries.     

Sequencing of intersecting lines by combined lifting process and scanning electron microscopy

The chronological order in which two intersecting writing or typed strokes were made can be determined for several combinations of writing media by scanning electron microscope (SEM) examination, a lifting and transfer technique using Kromekote paper, or a combination of the transfer technique followed by SEM examination of the remaining material in the intersection. When non-destructive examination cannot provide unambiguous determination of sequence, judicious choice by the document examiner of which technique to use for a given combination of writing media and paper type can be made using known characteristics of the materials involved. The range of line-crossings which can be reliably sequenced is greater using a combined transfer and SEM technique than when the examination is limited to either technique alone.
