Social Justice Attitudes and Their Demographic Correlates Among a Nationally Representative Sample of U.S. Adolescents

Compared to extant studies, this study uses more rigorous analyses to describe social justice attitudes and their correlates among a nationally representative sample of 2,811 U.S. ninth-graders. Females and adolescents with more educated mothers tended to express more support for social justice. Strikingly, about 90 % of adolescents believed that equal opportunity to obtain a good education exists in the U.S. Adolescents were also more likely to support abstract social justice principles rather than solutions that promote social justice: about 80 % agreed that all races and genders should have equal opportunities, but only 55 % reported that government should be responsible for individuals’ economic needs. Differences between U.S. adolescents’ and adults’ attitudes are noted, and implications for future research are presented.     

Elder neglect and the pathophysiology of aging

Elder neglect, one of the 6 forms of elder maltreatment, is difficult to diagnose and is underreported both in the scientific literature and to law enforcement. Recognizing fatal neglect is even more challenging especially with concurrent organic disease. Many entities can mimic elder neglect, and many age-related changes can result in pathology that may be confused with maltreatment. We retrospectively reviewed all forensic cases of individuals age sixty-five years and older which were referred for autopsy. Cases of fatal neglect were analyzed as to age, sex, race, cause of death, location of incident, perpetrator, victim-to-perpetrator relationship, and autopsy and ancillary findings. The cases studies totaled 8. The age range was 74 to 94 years. Two were white, 6 black, one male, and 7 female. The causes of death were sepsis due to severe decubitus ulcers and severe dehydration. Five cases occurred in the victim's home, and 3 occurred in an institution (nursing home/care facility). In 5 cases, the perpetrators were family members. The pathophysiology of aging with respect to elder maltreatment is reviewed.     

Effect of electron beam irradiation on forensic evidence. 2. Analysis of writing inks on porous surfaces

The effect of electron beam irradiation on a series of different writing inks is described. As the anthrax-tainted letters were discovered in October 2001, the U.S. government began to experiment with the use of the electron beam irradiation process for destroying such biological agents. Plans initially considered a large-scale countrywide use of this technology. However, over time the scope of this plan as well as the radiation dosage were reduced, especially when some adverse consequences to mailed items subjected to this process were observed. Little data existed at the time to characterize what level of damage might be expected to occur with common items sent through the mail. This was especially important to museums and other institutions that routinely ship valuable and historic items through the mail. Although the Smithsonian Institution initiated some studies of the effect of electron beam irradiation on archived materials, little data existed on the effect that this process would have on forensic evidence. Approximately 97 different black, blue, red, green, and yellow writing inks were selected. Writing ink types included ballpoint, gel, plastic/felt tip, and rollerball. All noncontrol samples were subjected to standard mail irradiation conditions used by the U.S. Postal Service at the time this experiment was performed. A video spectral comparator and thin-layer chromatography (TLC) analysis were used to evaluate both the control and the irradiated samples. Some published studies reported changes in the presence/absence of dye bands in the chromatograms of irradiated writing inks. Some of these studies report the formation of additional dye bands on the chromatogram while others report missing dye bands. However, using standard testing guidelines and procedures, none of the 97 irradiated inks tested were found to show any significant optical or chemical differences from the control samples. In addition, random testing of some of the ink samples using a second solvent system did not reveal any changes. However, one control ink did show some minor changes in optical properties and dye characteristics over time (but not TLC) while the irradiated sample remained stable. Significant changes in the ultraviolet fluorescence characteristics of the irradiated paper samples themselves (not inks) were also observed.     

Neuroimaging in Mild Traumatic Brain Injury

Neuroimaging in mild traumatic brain injury (mTBI) is reviewed. While computed tomography remains the acute standard for neuroimaging of mTBI, it is only sensitive to gross abnormalities and is typically performed as a measure to rule out more serious and life-threatening injury. Magnetic resonance imaging (MRI), especially at field strength of 3.0 T, is the follow-up neuroimaging standard for assessing potential underlying structural injury to the brain. Several MRI sequences are particularly sensitive to subtle hemorrhagic lesions and signal abnormalities in white matter, sensitive enough to detect pathology when present in mTBI. Clinical correlation of neuropsychological outcome with neuroimaging findings is discussed along with the future potential for functional neuroimaging in evaluating the mTBI patient.     

To Test or Not To Test?: The Value of Toxicology in a Delayed Overdose Death

A case demonstrating the necessity of thorough death investigation processes where toxicology plays an active role is presented. A 33‐year‐old white man presented to the emergency room in respiratory distress after an overdose episode where he was revived on the scene by fire rescue. His condition continued to deteriorate and he expired 6 days after the initial incident. No admission specimens were available for testing; however, there were specimens drawn 4 and 5 days after the incident. Drug paraphernalia from the scene was obtained by the laboratory through collaboration with local law enforcement. Drug paraphernalia was initially tested in the laboratory and after obtaining the results, the antemortem and postmortem specimens were tested identifying mitragynine and U‐47700, among other drugs. These results indicate the value in obtaining and testing drug paraphernalia, and the value of testing antemortem specimens even in the event of a delay.     

Average Probability that a "Cold Hit" in a DNA Database Search Results in an Erroneous Attribution

Abstract:  We consider a hypothetical series of cases in which the DNA profile of a crime-scene sample is found to match a known profile in a DNA database (i.e., a "cold hit"), resulting in the identification of a suspect based only on genetic evidence. We show that the average probability that there is another person in the population whose profile matches the crime-scene sample but who is not in the database is approximately 2( N  −  d ) p _A , where N is the number of individuals in the population, d is the number of profiles in the database, and p _A is the average match probability (AMP) for the population. The AMP is estimated by computing the average of the probabilities that two individuals in the population have the same profile. We show further that if a priori each individual in the population is equally likely to have left the crime-scene sample, then the average probability that the database search attributes the crime-scene sample to a wrong person is ( N  −  d ) p _A .     

Chilling Journalism: Can Newsgathering be Harassment or Stalking?

Newsgathering often requires journalists to ask uncomfortable questions or make multiple attempts to talk to unwilling sources. Some journalists have been accused of harassment, even when the plain language of state laws would not classify their actions as criminal conduct. In the rare instances that journalists actually were charged with harassment or subject to protective orders for stalking, district attorneys or judges typically did not allow them to be punished. This study, however, found nine statutes that might be applied to punish newsgathering activities that are neither hounding nor harassing. It also identifies language from statutes that clearly could not be applied to punish newsgathering communications by journalists. The article recommends that prosecutors and judges continue to prevent the application of criminal harassment and stalking laws to newsgathering activities.     

Asphyxia by tracheobronchial thrombus

Asphyxia secondary to airway obstruction has numerous underlying causes, both acute and chronic. Causes of chronic airway obstruction, such as neoplasms and tracheal scarring, are often clinically apparent well prior to asphyxia. Causes of acute airway obstruction may not be as obvious to clinicians or investigators. These include infections, anaphylactic reactions, status asthmaticus, inhalational injuries, and aspirations, which may result in acute obstruction and sudden death.We report the deaths of 2 individuals, a 43-year-old female and a 78-year-old female, both with adenocarcinoma. The 43-year-old was hospitalized with a stage III, poorly differentiated infiltrating ductal carcinoma of the breast metastatic to the lymph nodes. She was intubated to treat poor respiratory function and acidosis. A bronchoalveolar lavage was consistent with alveolar hemorrhage; no organisms were identified. Blood and "clot" were in her endotracheal tube, so the endotracheal tube was replaced. She became comatose and life support was withdrawn. At autopsy, a large red-gray thrombus obstructed the trachea and extended into the right bronchus. Microscopically, the entire clot was composed of fibrin, red blood cells, and some mucus. Findings of acute respiratory distress syndrome with hyaline membranes were identified. The cause of death was listed as acute respiratory distress syndrome with tracheobronchial thrombus. Experiencing a decline in mental status, the 78-year-old had metastatic adenocarcinoma of unknown primary. She developed sudden respiratory distress and an airway obstruction was discovered. After failure to relieve the obstruction, she decompensated and died. At autopsy, a large, red-gray thrombus obstructed the distal trachea and both bronchi. Microscopically, the thrombus was composed of fibrin, platelets, and red blood cells. The cause of death was asphyxia secondary to airway obstruction by thrombus. We present these 2 unusual cases of asphyxia and review of the literature focusing on asphyxia and the etiology of airway thrombi.     

Intent to Destroy: The Genocidal Impact of Forced Migration in Darfur, Sudan

The conflict in Darfur is now nearly three years old. Hundredsof thousands of civilians have been killed and millions moreremain unable to return to their homes, living the barest ofexistences in remote and often under-stocked and under-protectedcamps. Displaced populations are subject to malnutrition, diseaseand ongoing violence. Rape and other forms of sexual violenceremain a tool for instilling fear and controlling the civilianpopulation. Yet international will to protect and assist thevictims of the conflict remains weak, with governments and worldbodies bogged down debating the definition of genocide and theproper venues for eventual tribunals. This paper will examinewhether or not the conflict in Darfur does indeed amount togenocide, including a discussion of the role of forced displacementin reaching such a determination. It then looks at the 2005findings of the United Nations-sponsored International Commissionof Inquiry and discusses some of the reasons behind the internationalreluctance to reach a determination of genocide in the region.Lastly, it addresses the constructiveness of the genocide labelin the context of Darfur, and presents options for moving forwardwith a protection agenda regardless of what the conflict iscalled.
