Skull identification by means of superprojection using the electronic photo-composition technique, modified to the animated picture-difference procedure (author's transl)

Skull identification by electronic photo-composition can, with the help of a video-animation compositor, be further developed beyond the pure superprojection technique into an animated picture difference image. The employment of this combined technique to be recommended on account of the improved possibilities of control to be realized in the congruity of the superprojection composite picture.     

Improved skull identification using the superprojection technique with the help of a video-tape system (author's transl)

The photographic identification of a skull through the well-known superprojection technique can be modified and decisively improved by the use of a video-tape system. The identification method based on electronic photo composition is methodically simple to use. It offers the examiner the possibility to recognize the relationship between bone and soft part proportions, and the structure of the bone surface and the details of the soft part shape, as a concrete, tangible characteristic of identity to a substantially greater extent. The large number of controllable characteristics inherent in the ihgh degree of individuality of the skull offers not just an either/or "The skull fits"/ "It does not fit" into a photograph, but achieves proof of disproof of identity.     

Excepted substances: a comparison of Federal and state laws.

A state law has placed an obligation on the criminal investigation laboratories to screen and quantitate all preparations, both pharmaceutical and illicit, that fall under the provisions of "Excepted Substances." Without complete screens on these preparations, there is room for erroneous indictments as well as possible acquittals on technicalities.     

The Prime Minister's mailbag

Abstract. This study is based on examination of a randomly selected sample of 2,150 letters representing all the mail received by Prime Minister Trudeau between February 1969 and June 1972. The object of the study was to ascertain the characteristics of the letter-writers and the nature of their concerns, arguments and strategies. Through interviews with the staff of the Correspondence Section of the Prime Minister's Office we were also able to discover how the mail is processed. This is described in the last section of our paper. As one might expect, the mail is unrepresentative of the regional, linguistic and class diversity of Canada. Metropolitan areas, rich provinces and English-speakers are over-represented, as are people who have access to typewriters. There is, however, a sizable group of letters from the very poor who write the Prime Minister to complain of their victimization by government bureaucracy or by life in general. These letters are personal and apolitical and approach the Prime Minister in a deferential manner. They appear to us to be carefully and sympathetically answered, and to be probably effective in rectifying small problems. The bulk of the mail is policy-oriented, but probably not effective in influencing policy. Public attention to policy, as expressed in the mail, is extremely transitory and focuses particularly on topics with strong emotional content or on those affecting economic welfare. The mail seems only weakly related to the government's own policy priorities. Sommaire. Cette étude est fondée sur un échantillon de 2,150 lettres tirées du courrier par le premier ministre Trudeau entire février 1969 et juin 1972. Nous avons voulu identifier les catégories de personnes qui s'adressaient au premier ministre, et déterminer le but de leur correspondence et la nature de leur argumentation etc. Nous avons interviewé le personnel de la section de la correspondance du cabinet du premier ministre pour connaître la procédure de réponse à ce courrier. Nous avons constaté que le courrier n'est pas représentatif de la diversité régionale, culturelle et sociale du pays. Les plus fortunés, les habitants des grandes villes, et les habitants des provinces sont surreprésentés. II y a, cependant, une proportion assez élevée de lettres venant d'économiquement faibles qui se plaignent au premier ministre de leur traitement par la bureaucratic ou de la vie en générate. Leurs problèmes sont formulés en termes personnels, et ces personnes s'adressent au premier ministre respectueusement. Les réponses à ces lettres nous paraissent sympathiques et souvent efficacies quant au redressement des plaintes. Le gros du courrier concerne l'orientation de la politique mais son influence est sans doute limitée. L'attention du public à l'égard de la politique gouvernementale est conditionnée par les évènements, en particulier les évènements à contenu émotif ou ceux qui touchent de près le bien-être des correspondants. Ce courrier ne se réfère que très indirectement aux priorités politiques du gouveniement.     

Cultural Equivalence and Cultural Variance in Longitudinal Associations of Young Adolescent Self-Definition and Interpersonal Relatedness to Psychological and School Adjustment

Ethnic group differences in the contributions of self-definition (self-worth and efficacy) and interpersonal relatedness with parents and peers to changes in psychological and school adjustment were examined among 448 White, Black, and Latino girls and boys (11–14 years of age). Self-report questionnaires and school records were evaluated for socioeconomic and ethnic group differences in patterns of change over 1 year. Overall similarity in changes over time across ethnic groups was found for relatedness, self-definition, and psychological adjustment, although Black and Latino youth reported more overall adjustment difficulties, Black youth reported less positive relationships with parents, and lower SES youth reported less positive peer relationships than others. Ethnic group differences in changes to school adjustment, even after controlling SES, suggested a cultural variation in which often cited declines in school adjustment during middle school characterize White adolescents to a greater degree than Black or Latino adolescents. Ethnicity moderated associations of relatedness and self-definition with psychological and school adjustment such that Black and Latino youth appeared particularly vulnerable to experiences that threaten closeness and trust in relationships. Results pointed to potentially important situational and cultural differences in maladaptive and adaptive developmental processes across ethnicity.     

Interpersonal Correlates of Peer Victimization Among Young Adolescents

Empathy, prosocial behavior, the number of friends, self-reported popularity, and various forms of interpersonal forgiveness were examined as predictors of peer victimization among 52 7th and 8th graders attending a private school. Popularity was the strongest individual predictor of teacher-reported victimization with high popularity associated with low victimization. Malestudents reported significantly higher rates of victimization than females, prompting the decision to examine correlates of self-reported victimization separately by gender. Interpersonal forgiveness scores were the strongest predictors of self-reported victimization; however, different forms of forgiveness were the greatest predictors of male and female self-reported victimization. Implications are discussed.
