Correlates of syllogistic reasoning skills in middle childhood and early adolescence

Sixth, eighth, tenth, and twelfth graders, and college students, were given a preliminary test of categorical syllogistic reasoning ability. In a subsequent session, subjects were given other categorical syllogisms and asked to depict as many of the possible relationships between the A, B, and C terms of the syllogism as they could. The number of possible relationships, and the time it took to decide if other relationships were possible, did not differ among the noncollege groups. The results indicated, however, that the correlates of reasoning proficiency differed for those subjects younger and those older than about age 13.Support for this research was provided by the Spencer Foundation, whose generosity is greatfully acknowledged.Received the Ph.D. in Psychology and the M.S.E. in Computer Science from the University of Pennsylvania, and has research interests in the areas of formal and everyday reasoning, the development of reasoning skills, decision making, and conceptual development.Received the Ph.D. in Psychology from the University of Pennsylvania, and has research interests in the areas of language acquisition, conceptual development, and the development of reasoning skills.     

De Clérambault's Syndrome (Erotomania) and claims of psychiatric malpractice

De Clérambault's Syndrome or Erotomania was originally described as a delusional disorder in which a woman believes that an older man of higher social status is passionately in love with her. The patient's relentless pursuit of the delusional love object, often with escalating intrusiveness, may eventually involve threats or overt acts of retaliation, in response to repeated rejection, unrequited love, or alleged betrayal. Cases from the literature are reviewed in which the delusional romantic attachment involves the patient's psychiatrist or another medical specialist. The authors present a case involving a patient suffering from erotomania who develops a delusional fixation on her psychiatrist and, after her advances are repeatedly rejected, sues him for malpractice, alleging she had a sexual relationship with him in the course of treatment. The implications of the litigious paranoid, who uses the legal system to act out delusional concerns and retaliatory fantasies, are discussed. This is the first known case of an erotomanic patient claiming malpractice on the grounds that her psychiatrist had a sexual relationship with her.     

Fatal intravenous injection of potassium in hospitalized patients

We describe 4 cases of fatal intravenous injection of potassium in the hospital setting. These cases illustrate the subtlety of findings in such deaths and remind the forensic pathologist to consider this type of event in sudden, unexpected death of hospitalized patients.     

Streetwork at the crossroads: An evaluation of a street gang outreach intervention and holistic appraisal of the research evidence

Spurred by the success of public health violence interventions, and accelerated by policy pressure to reduce violence without exacerbating overpolicing and mass incarceration, streetwork programs—those that provide anti-violence services by neighborhood-based workers who perform their work beyond the walls of parochial institutions—have positioned themselves as the most important non–law-enforcement violence prevention option available to urban policy makers. Yet despite their importance, the state of the field seems difficult to interpret for academics and practitioners alike. In this article, we make several contributions that bring forth new findings and deliver new perspectives on streetwork as a violence reduction strategy. First, we offer an extended analytic review of the streetwork evaluation literature that connects the study of contemporary public health violence interventions to a preceding tradition of criminologically inspired streetwork studies. Second, we present the results of an impact evaluation of StreetSafe Boston (SSB)—a multiyear streetwork intervention that served 20 Boston gangs. We find that the SSB intervention had no detectable effect on violence among the gangs that it served. We conclude by offering a framework for understanding a field at multiple crossroads: past and present, proclaimed successes and failures, help and harm.     

'What's in a name?' The curious tale of the office of high commissioner

Members of the Commonwealth do not use the title 'ambassador' for the heads of diplomatic missions which they send to one another. Instead, they use the title 'high commissioner'. This article firstly examines how the office of high commissioner emerged to meet the representational needs of states owing allegiance to a common sovereign. Secondly, it explains why the office survived the transformation of the British empire into the modern Commonwealth of sovereign states. Thirdly, the article considers the factors that continue to make the office appealing to its holders and a diplomatic asset to their states.     

Effects of storage time on DNA profiling success from archived latent fingerprint samples using an optimised workflow

Due to recent improvements in forensic DNA testing kit sensitivity,there has been an increased demand in the criminal justice community to revisit past convictions or cold cases.Some of these cases have little biological evidence other than touch DNA in the form of archived latent fingerprint lift cards.In this study,a previously developed optimised workflow for this sample type was tested on aged fingerprints to determine if improved short tandem repeat(STR)profiles could be obtained.Two-year-old samples processed with the optimised workflow produced an average of approximately five more STR alleles per profile over the traditional method.The optimised workflow also produced detectable alleles in samples aged out to 28 years.Of the methods tested,the optimised workflow resulted in the most informative profiles from evidence samples more representative of the forensic need.This workflow is recommended for use with archived latent fingerprint samples,regardless of the archival time.     

DNA Purification Cell Lysis and Wash Step Modifications for Low-Template DNA Sample Processing,

As DNA technology becomes increasingly sensitive, forensic laboratories are receiving more low-template DNA samples. These samples, already low in DNA content, become even more challenging to process as the available DNA becomes further reduced during the extraction step. In this study, two extraction modifications were tested to determine if the cause of DNA loss could be identified and mitigated. A double lysis technique was used to test for DNA loss in the sample collection substrate, and lysate eluates were re-extracted to determine DNA loss from inefficient binding to the silica column. Both modifications showed DNA was lost at these steps. However, resulting STR profiles from these samples had fewer peaks and lower peak heights when compared to samples processed with no extraction modifications. Overall, the potential benefits of adding these extraction modifications for low-template DNA sample processing are not enough to justify the risk associated with additional manipulation.
