Further data on the development of red blood cell antigens Lu, Lu, and Co

One hundred and fifty-five cord cells were tested for the red blood cell antigens Lu^a, Lu^b and Co^b in order to collect data on the early postnatal expression of these markers. Additionally, dosage studies were carried out in 8–10-month-old heterozygous children. Antigens Lu^a and Lu^b revealed to be significantly less expressed in children of both ages compared with those of their mothers, whereas no such differences could be demonstrated in the expression of the antigen Co^b.     

Does WIC work? The effects of WIC on pregnancy and birth outcomes

Support for WIC, the Special Supplemental Nutrition Program for Women, Infants, and Children, is based on the belief that "WIC works." This consensus has lately been questioned by researchers who point out that most WIC research fails to properly control for selection into the program. This paper evaluates the selection problem using rich data from the national Pregnancy Risk Assessment Monitoring System. We show that relative to Medicaid mothers, all of whom are eligible for WIC, WIC participants are negatively selected on a wide array of observable dimensions, and yet WIC participation is associated with improved birth outcomes, even after controlling for observables and for a full set of state-year interactions intended to capture unobservables that vary at the state-year level. The positive impacts of WIC are larger among subsets of even more disadvantaged women, such as those who received public assistance last year, single high school dropouts, and teen mothers.     

Participatory action research in practice: a case study in addressing domestic violence in nine cultural communities

Participatory action research (PAR) is increasingly recognized as a viable approach to developing relationships with communities and working closely with them to address complex public health problems. In the case of domestic violence research, where ensuring the safety of women participants who are battered is paramount, participatory approaches to research that include advocates and women who are battered in research design, implementation, analysis, and dissemination are critical to successful and mutually beneficial projects. This article presents a case study of a PAR project that conducted formative qualitative research on domestic violence in nine ethnic and sexual minority communities. The article describes the specific ways in which a PAR approach was operationalized and discusses in detail how community participation shaped various stages of the research. Furthermore, specific actions that resulted from the research project are reported.     

New threats – different response: EU and NATO and Somali piracy

When the European Union (EU) launched its first military naval mission, EU NAVFOR Somalia, Atalanta, the states who are members of both the EU and the North Atlantic Treaty Organization (NATO) made a political choice: to prioritize the EU over NATO in their multilateral military efforts to fight piracy and its consequences. Thereby, Atalanta challenges the conventional assumption that EU security cooperation will remain limited. It also challenges the widely held belief that the European states will chose to act through NATO if dealing multilaterally with international security issues. How can we explain this decision? This analysis suggests that it can be explained in two phases where different mechanisms were at work. In the first phase, which can be accounted for from a neo-realist perspective, France, who held the Presidency, used particular favorable geopolitical conditions to put an autonomous EU operation on the agenda. However, agreement on the EU option cannot be explained as a result of strategic bargaining. Instead, in a second phase and in line with an alternative hypothesis building on the theory of communicative action, the EU member states came to support the French suggestion due to legitimacy considerations regarding the legal framework of the two operations.     

Evaluation of canine training aids containment for homemade explosive and components by headspace analysis and canine testing

While canines are most commonly trained to detect traditional explosives, such as nitroaromatics and smokeless powders, homemade explosives (HMEs), such as fuel–oxidizer mixtures, are arguably a greater threat. As such, it is imperative that canines are sufficiently trained in the detection of such HMEs. The training aid delivery device (TADD) is a primary containment device that has been used to house HMEs and HME components for canine detection training purposes. This research assesses the odor release from HME components, ammonium nitrate (AN), urea nitrate (UN), and potassium chlorate (PC), housed in TADDs. Canine odor recognition tests (ORTs) were used with analytical data to determine the detectability of TADDs containing AN, UN, or PC. Headspace analysis by gas chromatography/mass spectrometry (GC/MS) with solid-phase microextraction (SPME) or online cryotrapping were used to measure ammonia or chlorine, as well as other unwanted odorants, emanating from bulk AN, UN, and PC in TADDs over 28 weeks. The analytical data showed variation in the amount of ammonia and chlorine over time, with ammonia from AN and UN decreasing slowly over time and the abundance of chlorine from PC TADDs dependent on the frequency of exposure to ambient air. Even with these variations in odor abundance, canines previously trained to detect bulk explosive HME components were able to detect all three targets in glass and plastic TADDs for at least 18 months after loading. Detection proficiency ranged from 64% to 100% and was not found to be dependent on either age of material.     

The dynamic political economy of support for Barack Obama during the 2008 presidential election campaign

In recent years, students of voting behavior have become increasingly interested in valence politics models of electoral choice. These models share the core assumption that key issues in electoral politicds typically are ones upon which there is a widespread public consensus on the goals of public policy. The present paper uses latent curve modeling procedures and data from a six-wave national panel survey of the American electorate to investigate the dynamic effects of voters’ concerns with the worsening economy—a valence issue par excellence—in the skein of causal forces at work in the 2008 presidential election campaign. As the campaign developed, the economy became the dominant issue. Although the massively negative public reaction to increasingly perilous economic conditions was not the only factor at work in 2008, dynamic multivariate analyses show that mounting worries about the economy played an important role in fueling Barack Obama’s successful run for the presidency.     

Assessing the relevance of self-reported ADHD symptoms and cognitive functioning for psychopathy using the PCL-R and the TriPM

Psychopathy and ADHD are highly comorbid disorders, possibly linked to the underlying trait of impulsivity. It is therefore likely that ADHD symptoms are also of importance when studying cognitive functioning linked to psychopathy. Few studies of psychopathy and cognitive functioning have taken ADHD symptoms into account. In this cross-sectional study, male offenders (n = 201 of whom 105 were neuropsychologically tested) were recruited from all high security correctional facilities in Sweden. The aim of the study was to investigate if self-reported ADHD symptoms and cognitive functioning could predict specific subcomponents of psychopathy in offenders. Results showed that self-rated ADHD symptoms (ASRS) and psychopathy were highly correlated. Furthermore, the associations of ASRS and PCL-R Facet 3, as well as TriPM Disinhibition, were remarkably high. As expected, ASRS was not related to either Facet 1 or 2 of the PCL-R, or to TriPM Boldness. Cognitive functioning did not contribute in predicting psychopathy beyond the effect of ASRS. The high overlap in reported symptoms highlights the importance of thorough clinical assessments to be able to distinguish psychopathic personality traits from ADHD and lessen the risk of misdiagnosis. Further, it points to the need of finding discriminative measures possibly linked to etiological underpinnings.
