A post-residential-treatment follow-up of socially and emotionally deviant adolescents in Israel

Fifty-five emotionally and socially deviant but normally intelligent adolescents who had spent 2–7 years in a children's and apprentice home in Israel were followed up 5–9 years after they had left the institution. Their postresidential social and vocational careers were evaluated by means of personal interviews, home visits, and reports from employers, and it was found that good adjustment was substantially related to family background variables (having lived with biological parents prior to residential placement, mutual positive relationship between parent and child, being first born) as well as to satisfactory behavior and performance in peer group, school, and workshop during residence. Level of intelligence, unrelated to overall adjustment, correlated positively with vocational status and income at followup. On the other hand, length of stay in the apprentice home had no impact on postresidential adaptation to work and society. Fewer than 10% of exinmates expressed retrospectively a negative attitude toward their stay in the institution. The importance of paying more attention to the eventual long-term and enduring impact of family relationship on the residential and postresidential behavior of adolescents is discussed, suggesting a shift of emphasis in evaluating factors involved in institutional treatment. Findings also indicate that later social and vocational success may be fairly predicted from observation of behavior during the stay in the institution.The empirical study reported in this article was supported by a grant from the Australian Women's International Zionist Organisation (WIZO), through the initiative of Mrs. Martha Jacobson, Melbourne, chairman of the board of directors.Received his Ph.D. in Psychology and Special Education from the University of Zurich, Switzerland, in 1954. Main research interests are normal and abnormal child development, high-risk infants, adolescence, and handicapped children.Main research interest is institutional care.     

Analysis of carbohydrates in seized heroin using capillary electrophoresis

Illicitly produced heroin is commonly cut with carbohydrates to increase bulk. The analysis of these solutes is important for legal and intelligence purposes. A capillary electrophoresis (CE) method was developed for the qualitative analysis of dextrose, lactose, sucrose, inositol, and mannitol in heroin exhibits. For this method, a 64 cm (55.5 cm to detector window) by 50 mum capillary was used with the Agilent Basic Anion Buffer modified to pH 12.1. This separation was performed at 25 degrees C with a voltage of 20 kV and indirect detection with 2,6-pyridinedicarboxylic acid as the visualization reagent. The methodology is also applicable for the screening of inorganic and organic anions using indirect detection, and acidic adulterants using direct detection. For a run time of 13 min, the relative standard deviation (n = 6) of the methodology was better than 0.36% for migration times and less than 2.6% for corrected peak areas. For the analysis of carbohydrates and acidic adulterants in seized heroin, excellent agreement was obtained between CE and nuclear magnetic resonance spectroscopy.     

The human ear: its role in forensic practice

The human ear has much to offer investigators in relation to many areas of forensic practice including forensic pathology, anthropology, identification and facial reconstruction and yet its full potential is often overlooked. This review paper explores current knowledge related to the human ear drawing attention to those situations where the ear could play a valuable role in a forensic investigation.     

On collective goods,private wealth,and the core solution of simple games with sidepayments

This essay identifies consequences for the core solution in a class of social decision problems concerning the provision of collective goods (or bads) if the rules are modified to permit sidepayments. In these problems, a kind of formal decision procedure that includes any weighted or unweighted majority rule governs only the decision about collective goods. Each decision about collective goods, however, implies a vector of the agents' endowments of private wealth that can, but need not, vary across the alternatives. Any agent may offer to make sidepayments from this endowment that are contingent on the collective goods decision, but the agent holds preferences that, given any fixed decision about collective goods, strictly increase in the agent's own wealth. The results indicate that the core's response to introducing the possibility of sidepayments depends on whether any agent possesses a veto over the collective goods decision. If no one has a veto, then an outcome belongs to the core of the game with sidepayments only if no sidepayment is made and the same decision about collective goods belongs to the core of the associated game without sidepayments. In this case, introducing the possibility of sidepayments does not bring a new collective goods decision into the core. Indeed, merely adding the possibility of sidepayments can cause the core to vanish. On the other hand, if at least one agent possesses a veto, then introducing sidepayments can (but need not) lead to a new core solution concerning the decision about collective goods. In any such new solution, at least one agent who has a veto — but no one who lacks it — receives a sidepayment.     

White Voters and African American Candidates for Congress

The vast majority of African American officeholders are elected from jurisdictions with sizable numbers of African Americans. The most common explanation for this phenomenon locates the cause among white voters who are reluctant to vote for black candidates, which thereby limits the electoral prospects of black candidates in white constituencies. This study analyzes exit poll data from the 1996 and 1998 House elections in order to test the notion that white voters are averse to black candidates. Despite theoretical expectations that predict the existence of white voter discrimination against African American candidates, remarkably little is apparent. Thus, other explanations for patterns of African American officeholding in the United States need to be pursued.

Identifying Fatal Head Injuries on Postmortem Computed Tomography Using Convolutional Neural Network/Deep Learning: A Feasibility Study

Postmortem computed tomography (PMCT) is a relatively recent advancement in forensic pathology practice that has been increasingly used as an ancillary investigation and screening tool. One area of clinical CT imaging that has garnered a lot of research interest recently is the area of “artificial intelligence” (AI), such as in screening and computer-assisted diagnostics. This feasibility study investigated the application of convolutional neural network, a form of deep learning AI, to PMCT head imaging in differentiating fatal head injury from controls. PMCT images of a transverse section of the head at the level of the frontal sinus from 25 cases of fatal head injury were combined with 25 nonhead-injury controls and divided into training and testing datasets. A convolutional neural network was constructed using Keras and was trained against the training data before being assessed against the testing dataset. The results of this study demonstrated an accuracy of between 70% and 92.5%, with difficulties in recognizing subarachnoid hemorrhage and in distinguishing congested vessels and prominent falx from head injury. These results are promising for potential applications as a screening tool or in computer-assisted diagnostics in the future.
