Do economic conditions influence how theorists view adolescents?

Eighty-nine articles in thePedagogical Seminary and theJournal of Genetic Psychology appearing during two economic depressions and the two world wars were analyzed for their adolescent ideologies. A systematic, ideological bias in the content of these articles was found to be statistically significant. In times of economic depression theories of adolescence emerge that portray teenagers as immature, psychologically unstable, and in need of prolonged participation in the educational system. During wartime, the psychological competence of youth is emphasized and the duration of education is recommended to be more retracted than in depression. The objective, scientific nature of theory building is questioned and discussed.Received Ph.D. in Educational Psychology from the University of Minnesota.

Attentional and intellectual deficits in unmedicated behavior-disordered adolescent inpatients

The authors examined the hypothesis that impairments in attention and verbal intelligence are associated with seriously maladaptive social behavior in behavior-disordered, hospitalized adolescents. Twenty-five unmedicated inpatients with disruptive behavior disorder diagnoses were rated during a one-month period for frequency of severe disruptive episodes, or critical incidents (CI); these included assaults, behavior resulting in the use of restraints, etc. All subjects independently received intelligence testing and continuous performance testing (CPT). Based on CI scores, subjects were divided into a high-CI group (CI>5; N=9) and a low-CI group (CI<4; N=16). On the CPT, the high-CI group showed more impairment in perceptual sensitivity (d; this group also had lower verbal IQ scores. (Both findings were significant at the p<.05 level.) The latter result was largely due to differences in Comprehension subtest scores. These results support the hypothesis, and may have implications for the treatment of behavior-disordered adolescents.Received M.D. from the University of Wisconsin, Major research interests are adolescent psychopathology, disruptive behavior disorders, and information processing.Received Ph.D. from the University of Wisconsin.

Form follows function: Applying photographic content analysis to forensic firearm identification

Drawing forensic conclusions from an image or a video is known as “photographic content analysis.” It involves the analysis of an image, as well as objects, actions, and events depicted in images or video. In recent years, photographic depictions of objects suspected as illegal firearms have substantially increased, appearing on CCTV surveillance footage, captured by mobile phones and shared on social media. However, the law in Israel states that a person can be charged with illegally possessing a firearm only if it can be proven that the object is capable of shooting with lethal bullet energy. This becomes more challenging in cases where the firearm was not physically seized, and the evidence exclusively consists of images and video. In this study, photographic content analysis was applied to images and video where objects suspected as commercial or improvised firearms had been depicted. An image and event sequence reconstruction video databases of both firearms and replicas were created in order to better define firearm-specific functional morphological features. We demonstrate that it is possible to classify an object as a firearm by analyzing the functional, and not only the esthetic, morphology in images and video. It is also shown that event sequence reconstruction in video may be used to infer that an object suspected as a firearm has the capacity to shoot by confirming the occurrence of a shooting act or shooting process. Thus, photographic content analysis may be used to forensically establish that an object depicted in an image or a video is a firearm by ruling out other known scenarios, and without physically seizing it.
