Reconsidering the Measurement of Political Knowledge

Political knowledge has emerged as one of the central variablesin political behavior research, with numerous scholars devotingconsiderable effort to explaining variance in citizens' levelsof knowledge and to understanding the consequences of this variancefor representation. Although such substantive matters continueto receive exhaustive study, questions of measurement also warrantattention. I demonstrate that conventional measures of politicalknowledge—constructed by summing a respondent's correctanswers on a battery of factual items—are of uncertainvalidity. Rather than collapsing incorrect and "don't know"responses into a single absence-of-knowledge category, I introduceestimation procedures that allow these effects to vary. Grouped-datamultinomial logistic regression results demonstrate that incorrectanswers and don't knows perform dissimilarly, a finding thatsuggests deficiencies in the construct validity of conventionalknowledge measures. The likely cause of the problem is tracedto two sources: knowledge may not be discrete, meaning thata simple count of correct answers provides an imprecise measure;and, as demonstrated by the wealth of research conducted inthe field of educational testing and psychology since the 1930s,measurement procedures used in political science potentiallyresult in "knowledge" scales contaminated by systematic personalityeffects.     

Extraction and analysis of flunitrazepam/7-aminoflunitrazepam in blood and urine by LC-PDA and GC-MS using butyl SPE columns

The forensic toxicology community has recognized flunitrazepam and its metabolite (7-aminoflunitrazepam) as compounds of concern for several years. In this procedure, the analytes were extracted from whole blood and urine onto single mode solid phase cartridges (butyl) using nitrazepam as an internal standard. The columns were washed with distilled water and hexane. All three compounds were eluted from the sorbent using an ethyl acetate-methanol solvent mixture. After collection and evaporation of the solvent, the residue was dissolved in A, 0.1% (v/v) aqueous trifluoroacetic acid for HPLC-PDA analysis or B, ethyl acetate for derivatization with pentafluoropropionic anhydride (PFPA) for analysis by gas chromatography-mass spectrometry (selected ion monitoring, SIM). A limit of quantitation for this method using HPLC-PDA was found to be 5 and 1.0 ng mL(-1) by SIM.     

Neck injuries caused by automatic two-point seat belts: an analysis of four cases

Although seat belts significantly reduce the extent and severity of injuries sustained by motor vehicle occupants, seat belts are known to be associated with chest and abdominal trauma. Less commonly understood are severe neck injuries caused by the use of two-point automatic shoulder harnesses without concurrent use of a manual lap belt. Such injuries may include cervical spine fractures, craniocervical dislocations and rarely decapitation. Recognizing patterned injuries caused by seat belts and the ability to correlate autopsy findings with the circumstances surrounding the death will allow for correct interpretation of seat-belt related trauma. The four cases described detail fatal neck injuries as a result of improper seat belt use in which an automatic two-point shoulder harness was used without a manual lap restraint. In two of the cases, the victims were decapitated.     

PTSD Symptoms Experienced and Coping Tactics Used by Crime Scene Investigators in the United States

Few investigations have assessed the prevalence of posttraumatic stress experiences among Crime Scene Investigators (CSIs). We recruited a nationwide sample of 225 CSIs to complete online questionnaires assessing PTSD symptoms, use of specific coping tactics, perceived social support, trait resilience, and demographics. Seven symptoms had been experienced by at least 50% of participants during the previous month, and 9.3% had total checklist scores suggestive of PTSD. A significant regression analysis revealed that higher PTSD scores were associated with drinking alcohol more frequently to deal with stress, admitting more frequently one could not deal with stress and not trying to do so, lower social support, getting angry and letting emotions out more frequently, lower resilience, and finding comfort in one's religious beliefs. Given the proportions of CSIs that experience exposure‐related stress, more should be done to mitigate the prevalence and severity of these symptoms.     

“Hut ab,” “Promenade with Kamerade for Schokolade,” and the Flying Dutchman: British Soldiers in the Rhineland, 1918–1929

This essay explores the social history of the “British Army of the Rhine,” especially their interactions with the German population, over the eleven-year period of occupation in Cologne and part of the Rhineland. It covers the initial, sometimes fraught establishment of the occupation and interactions with the civil population, especially the perennial problem of British soldiers’ relations with German women. These were initially prohibited altogether, but the rule was quickly relaxed, and the British authorities even accepted and regulated the use of brothels, leading to criticisms back home. The essay also discusses the comparatively small number of serious violent crimes (including four murders) during the occupation, and concludes that the occupation was characterized on both sides by grudging acceptance and some degree of forbearance.     

Interviewing to Elicit Cues to Deception: Improving Strategic Use of Evidence with General-To-Specific Framing of Evidence

Previous research has demonstrated that the strategic use of evidence (SUE) approach of interviewing criminal suspects is effective at eliciting cues to deception. This study aims at expanding on the SUE approach by testing the technique of general-to-specific evidence framing. We conducted an experiment using a mock terrorism paradigm. Guilty participants took part in a simulated act of terrorism, while innocent participants performed a similar act involving no transgression. All participants (N?=?102) were then interviewed using one of four evidence disclosure styles (early disclosure, late disclosure, 2-step disclosure, or 4-step disclosure). We expected that disclosing evidence to the suspect gradually, with increasing specificity, would induce guilty suspects to alter their statements to a greater extent than innocent suspects. General-to-specific evidence framing effectively discriminated between guilty and innocent suspects, but results only partially supported the hypotheses.     

Question wording and mass policy preferences: The comparative impact of substantive information and peripheral cues

Understanding the dynamics of mass political behavior requires attention to the mechanisms and processes citizens use in evaluating political affairs. At its structural core, a political appraisal has much in common with most of the other decisions individuals must make each day. Consequently, insight can be gained by examining political judgments from the perspective of those psychological theories concerned with information processing and decision making. More specifically, because the American citizen typically must maximize cognitive efficiency when evaluating political phenomena, those psychological mechanisms that facilitate expedience and simplicity in decision making are likely to operate on a great diversity of political judgments. Hence theoretical perspectives concerning the role of heuristic principles of judgment may be of considerable utility for the study of mass political behavior. One such perspective, the heuristic‐systematic model, is discussed. The tenets of the heuristic‐systematic model guide quasi‐experimental examination of the influence of variance in question wording on public support for the Reagan defense build‐up. Results indicate that source cues enable individuals to apply source evaluations when forming policy assessments but that the impact of source cues is overwhelmed when individuals are simultaneously exposed to relevant policy information.
