Skill Specificity and Attitudes toward Immigration

Labor market competition theories explaining anti‐immigrant attitudes have received limited or no empirical validation in recent literature. This has led researchers to highlight education and cultural values as the main, if not the sole, drivers of attitudes toward immigration. We present a new labor market competition theory focusing on job availability rather than foreign labor supply. This theory predicts that individuals with low transferable skills in the labor market will articulate a subjective sense of job insecurity and higher hostility toward migrants. Our cross‐classified, longitudinal, and difference‐in‐differences models reveal that skill specificity is a strong driver of anti‐immigrant attitudes, and they suggest that economic competition theories cannot be dismissed. By shifting the attention from supply to demand in the labor market, and from actual to potential competition with migrants, we show that the highly educated are far from immune to anti‐immigrant attitudes.     

The logic and pathologies of local and regional economic development strategies

State and local economic development programs are often loaded with tax incentive and promises of deregulation designed to attract new businesses, encourage expansions, and cultivate new firms. There is little evidence that tax relief and deregulation are effective tools for economic development, however. This article examines the logic of public sector participation in economic development, questions the effectives of typical development policies, and suggests alternatives, including tax-base sharing, greater regional cooperation, and human capital development.     

A quantitative differentiation method for plastic bags by wide angle X-ray diffraction for tracing the source of illegal drugs

Thirty-three shopping bags, commonly encountered in the packaging of drug doses, were characterized by wide angle X-ray diffraction (WAXD). Using this single technique, without sample preparation, nearly all the considered samples could be differentiated, achieving a discriminating power of 0.992. The rather large degree of variability existing in grocery bags, even though they are mass produced, was shown, confirming that these items can be useful in tracing the source of illicit drug doses.     

Cuts and tears on a paper towel: a case report on an unusual examination of damage

The examination of damage to a paper towel, an item of evidence in a murder case, is described. Simulations performed with selected tools and the observation of the lacerations present on the towel permitted to infer that they were originated by cleaning of a pointed and sharp implement. Some marks, considered characteristic of scissors, were detected on the exhibit. This experimental outcome resulted critical in challenging the declarations of the suspect. A rather significant analogy between damage examination on paper towels and on textiles was established.     

Towards a "crime pollen calendar" - pollen analysis on corpses throughout one year

A palynological study was carried out on 28 corpses brought in one year (June 2003-May 2004) to the morgue of the Institute of Legal Medicine of Parma (Northern Italy). This preliminary research focuses on the date of death, which was known for all corpses examined. Pollen sampling and analyses were made with the first aim of comparing the pollen grains found on corpses with those diffused in the atmosphere in the region in the same season as the known date of death. Eyebrows, hair-line near the forehead, facial skin and nasal cavities were sampled. Most of the corpses had trapped pollen grains, with the exception of two December corpses. All pollen grains were found with cytoplasm and in a good state of preservation. In this way, a series of reference data was collected for the area where the deaths occurred, and we examined whether pollen grains on corpses could be an index of the season of death. To verify this hypothesis, the pollen analyses were compared with data reported in the airborne pollen calendars of Parma and the region around. Pollen calendars record pollen types and their concentrations in the air, month by month. The quantity of pollen recorded on corpses did not prove to be directly related to the quantity of pollen in the air. But qualitatively, many pollen types which are seasonal markers were found on corpses. Main corpse/air discrepancies were also observed due to the great influence that the local environmental conditions of the death scene have in determining the pollen trapped by a corpse. Qualitative plus quantitative pollen data from corpses appeared helpful in indicating the season of death. A preliminary sketch of a "crime pollen calendar" in a synthetic graphic form was made by grouping the corpse pollen records into three main seasons: A, winter/spring; B, spring/summer; C, summer/autumn. Trends match the general seasonal trend of pollen types in the air.     

Exposure to interpersonal violence as a predictor of PTSD symptomatology in domestic violence survivors

This study examines the interrelationships between childhood abuse, exposure to maternal domestic violence, and posttraumatic stress disorder (PTSD) symptomatology in a multiethnic sample of 111 adult female residents of a domestic violence (DV) shelter. Participants completed structured interviews about the DV and their prior violence exposure, as well as the Impact of Event Scale-Revised. As hypothesized, there was high co-occurrence between exposure to maternal DV and childhood physical and sexual abuse, and the frequency of lifetime violence exposure predicted PTSD symptomatology. A series of multiple regressions indicated a more complex pattern of relationships, in which specific forms of prior violence exposure predicted different PTSD symptom dimensions. A history of witnessing maternal DV predicted intrusion symptoms, and a history of childhood sexual abuse predicted hyperarousal symptoms. Ethnicity was not related to levels of violence exposure or to PTSD symptoms. Clinical implications of the findings are discussed.
