The effect of e-cigarette taxes on pre-pregnancy and prenatal smoking

E-cigarette taxes are an active area of legislation and have important regulatory implications by proxying e-cigarette accessibility. We examine the effect of e-cigarette taxes on prepregnancy and prenatal smoking using the near-universe of births to mothers conceiving between 2013 and 2019 in the United States. Using fixed effect regressions, we show that e-cigarette taxes increase prepregnancy and prenatal smoking. We also find evidence that e-cigarette taxes reduce prepregnancy and 3rd trimester e-cigarette use. Finally, we show that e-cigarette taxes increase news coverage of e-cigarettes and raise perceptions of risk of e-cigarettes.     

Using "Shocks and Rumors" to Teach Adaptive Thinking

The business landscape is constantly changing. Moreover, because of globalization, increased competition, and instant communication, the rate of change is accelerating. A student who has practiced only static scenarios is ill prepared to recognize, process, or adapt to changing negotiation issues and interests. Thus, negotiation instructors must change our practices to prepare students to succeed in the increasingly dynamic negotiation situations they will face by utilizing simulations that are also dynamic. This article reviews research on adaptive thinking, applies it to negotiation training, and provides examples of dynamic simulations that require students to adapt. Finally, it offers advice on how to make existing cases dynamic by using "shocks and rumors."     

Measuring the impact of public perceptions on child welfare workers

The Public Perceptions of Child Welfare Scale measures how the social environment influences child welfare workers, including their job satisfaction and intent to leave. Psychometric studies have validated the scale for private child welfare workers, but there are no validation studies with public agency staff. This study fills that gap, showing stigma and respect are important constructs that also predict worker intent to leave. This research found an additional construct, blame, which was not present in private worker validation studies. The scale provides an important tool for the field as we continue to build evidence for effective recruitment and retention.     

Inferring the Number of Contributors to Complex DNA Mixtures Using Three Methods: Exploring the Limits of Low‐Template DNA Interpretation

In forensic DNA casework, the interpretation of an evidentiary profile may be dependent upon the assumption on the number of individuals from whom the evidence arose. Three methods of inferring the number of contributors—NOCIt, maximum likelihood estimator, and maximum allele count, were evaluated using 100 test samples consisting of one to five contributors and 0.5–0.016 ng template DNA amplified with Identifiler^® Plus and PowerPlex^® 16 HS. Results indicate that NOCIt was the most accurate method of the three, requiring 0.07 ng template DNA from any one contributor to consistently estimate the true number of contributors. Additionally, NOCIt returned repeatable results for 91% of samples analyzed in quintuplicate, while 50 single‐source standards proved sufficient to calibrate the software. The data indicate that computational methods that employ a quantitative, probabilistic approach provide improved accuracy and additional pertinent information such as the uncertainty associated with the inferred number of contributors.     

The Effect of Variation in Intact Family Forms on Deviant and Antisocial Behavior

Family form sets the stage for a host of adolescent behavioral outcomes. We draw on research, theory, and methodology from within Criminology, Demography, and Family Sociology to examines the effect of variation in intact family form on antisocial and deviant behavior. We find higher antisocial and deviant behavior among youth residing in households where one of the parents has a child from a previous relationship and the parents are currently married but were cohabiting at the time of the birth of their eldest child.     

Early detection and early intervention in prison: improving outcomes and reducing prison returns

Our aim was to investigate whether early detection was feasible in prison and whether it could improve mental health outcomes in young prisoners. A secondary aim was to explore whether it can reduce returns to prison. Between 2011 and 2014, a total of 2115 young prisoners were screened, 94 (4.4%) met criteria for ultra-high risk for psychosis and were offered an intervention, 52 actually received it. Return to prison data were sought on the 52 participants, receiving a formal intervention. Of the 52 prisoners who received an intervention, 30.8% returned to custody compared to national average reconviction rates of between 45.4 and 66.5%. Our results suggest that early detection is a feasible option in a prison setting, improving mental health outcomes and reducing returns to prison. Mental health outcomes were recorded for a sub-sample of those receiving the intervention. The results indicated statistically significant improvements on measures of depression, anxiety and psychological distress.     

Carbon monoxide concentrations in the 2009 Victorian Bushfire disaster victims

Blood was available for the estimation of carboxyhemoglobin saturation (COHb) in 30 of the 173 persons who died in the Victorian bushfires in February 2009. The ages of these 30 deaths ranged from 3 to 80 years and there were 8 females. 13 cases (43%) were considered negative (less than 5% COHb), 12 (40%) were between 5 and 40% COHb, 2 (6.7%) between 40 and 50% and 3 (10%) were greater than 50% COHb. There were 6 persons either found within a building or a car and the COHb in these cases ranged up to 69% (mean 50%). There were 5 cases where the location was unable to be determined as either indoor or outdoor due to the extensive nature of the fire. The remaining 19 deceased persons were all located outside in the open and the concentration of COHb in these cases ranged up to 30% (mean 19%). Hydrogen cyanide was only detected in two deceased persons at concentrations of 0.5 and 2.7 mg/L, respectively. 13 deceased were found to have soot in the airways following necropsy but this did not correlate with the COHb levels.     

Individual and contextual variation in EU issue voting: The role of political information

Increasing politicization in EU member states about European issues can be expected to strengthen the impact of attitudes towards Europe on vote choice in European Parliament (EP) elections. At the same time this impact is likely to vary between voters and contexts as a function of political information. This study explores the role of political information in explaining individual and contextual heterogeneity in the degree of EU issue voting. Using a two-step hierarchical estimation procedure to explore both individual and contextual variation, we show that while EU issue voting in the 2009 EP elections is only slightly more pronounced among the politically sophisticated, it is clearly more extensive in contexts that provide higher levels of political information on European matters.     

Postmortem Measurement of Human Chorionic Gonadotropin in Vitreous Humor and Bile

Abstract: Postmortem human chorionic gonadotrophin (HCG) blood assay can confirm postmortem diagnosis of pregnancy or document situations in which HCG levels are elevated. In some cases, however, blood sampling is not possible at autopsy. In this study, HCG was quantified by enzyme‐linked fluorescent assay (ELFA) in the bile (n = 5), vitreous humor (n = 4), and postmortem blood (n = 4) of five pregnant women. There were no false negatives in the pregnant subjects (n = 5) or false positives in controls (n = 34), enabling this test to be recommended for routine use in forensic contexts in which the detection of elevated HCG levels could be of interest.     

Deviant Youth Groups in Italy and France: Prevalence and Characteristics

This paper sets out to compare the existence of Juvenile deviant groups in both France and Italy and their characteristics. The comparison between Italy (N = 5,236) and France (N = 3, 353) is based on the ISRD study of the year 2006 and shows that the term “gang” is commonly used to refer to a group of friends only. The strongest associated variables in both countries to illegal acts are the acceptance of doing illegal things, taking part in delinquent acts, considering the group as a gang as well as spending a lot of time in public places. Delinquent activity of Juvenile delinquent groups varies from one country to another and the French respondents show a greater participation in deviant youth groups than the Italians. Results show some differences in gender participation with a greater involvement of boys, although girls also take part in deviant or delinquent activities, both in Italy and France. At risk behaviour significantly characterises the young participants as well as victimisation. This last point highlights that although deviant or potentially dangerous, these young people are also more vulnerable and in need of protection.
