A Quantitative Assessment of the Risks from Illegally Imported Meat Contaminated with Foot and Mouth Disease Virus to Great Britain

Foot and mouth disease (FMD) is considered by many as the most important animal disease in the world. FMD is highly contagious and outbreaks incur significant costs as affected countries are severely limited in their ability to trade. A number of trade commodities may be contaminated with FMD virus (FMDV) including animal products, for example, meat. As a member of the European Union, Great Britain (GB) has put in place a number of regulations to prevent the importation of pathogens in imported meat products. However, the illegal importation of meat provides a route by which safety controls may be circumvented and meat from FMD affected areas may be imported. This study assesses the FMD infection risk posed to the livestock population of GB from the illegal importation of meat, and estimates the major contributors to this overall risk, through the development of a quantitative risk assessment model. From model results, the total amount of illegal meat entering GB each year is estimated on average to be 11,875 tonnes. with 90% certainty that this is between 4,398 and 28,626 tonnes per year; of which between 64.5 and 565 kg are contaminated with FMDV. This flow of illegal meat results in an estimate of a frequency of FMD infection in GB livestock of 0.015 cases of infected animals per year, with 90% certainty it is between 0.0017 and 0.053. Imports from the region Near and Middle East account for 47% of this risk, and 68% of the risk is attributed to bone-in and dried de-boned products.     

The Indirect Effect of Child Maltreatment Severity on Adult PTSD Symptoms through Anxiety Sensitivity

Although the rate of posttraumatic stress disorder (PTSD) among survivors of child maltreatment is high, individuals differ in symptom severity and many do not experience clinically significant levels of psychopathology. The present study tested the indirect effects of child maltreatment severity on adult PTSD, suicidal ideations, and alcohol dependence via anxiety sensitivity. A sample of 336 participants (mean age of 22.81 years, SD = 8.93; 70.2% female) completed an online survey of child abuse and neglect, anxiety sensitivity, PTSD symptom severity, suicidal ideation severity, and alcohol dependence severity. The results revealed significant indirect effects of child maltreatment on PTSD symptom severity through cognitive and social concerns, but not physical concerns. No direct or indirect effects were demonstrated for suicidal ideations or alcohol dependence severity. These findings elucidate mechanisms in the robust relationship between child maltreatment and adult PTSD symptoms and can potentially inform future research on mechanisms of change in psychotherapy.     

Exposure Assessment of TSEs from the Landspreading of Meat and Bone Meal

Recent changes in European legislation have meant that certain processed abattoir waste, which has been appropriately heat treated and ground to a specified particle size, can be spread on nonpasture agricultural land. This has opened the way for the potential landspreading of mammalian meat and bone meal (mMBM) derived from animals slaughtered for human consumption. This article reports on two separate case studies (Study 1 carried out in Great Britain (GB) and Study 2 carried out in Ireland) on the potential exposure to TSE infectivity following the spreading of abattoir waste (derived from animals slaughtered for human consumption) on nonpasture agricultural land. For Study 1, the average TSE infectivity on nonpasture agricultural land per year from sheep with scrapie was found to be higher (five orders of magnitude) than that estimated for BSE in cattle (3.9 x 10(-3) Ovine Oral ID(50)/ton of soil compared to 3.3 x 10(-8) Bovine Oral ID(50)/ton of soil). The mean estimate for BSE in sheep was 8.1 x 10(-6) Ovine Oral ID(50)/ton of soil. The mean level of infectivity in mMBM was assessed to be 1.2 x 10(-5) and 2.36 x 10(-5) ID(50)/ton of mMBM for Study 1 and 2, respectively. For Study 2 the spreading of mMBM was estimated to result in infectivity on nonpasture land of 1.62 x 10(-8) Bovine Oral ID(50)/m(3). The mean simulated probability of infection per year per bovine animal was 1.11 x 10(-9). Given the low infectivity density and corresponding low risks to bovines the spreading of mMBM could be considered a viable alternative for the utilization of mMBM.     

Reconsidering the Marielito Legacy: Race/Ethnicity,Nativity, and Homicide Motives*

Objective. This article investigates how race/ethnicity is associated with specific types of violent crime such as killings between intimates, robbery homicide, or drug‐related killings. We extend the study of the role of race and ethnicity for violence by examining five ethnic/immigrant groups, including the Mariel Cubans—a group singled out by many as particularly drug‐crime‐prone. Methods. Using 1980 through 1990 homicide data for the City of Miami, we use multinomial logistic regression to examine the association between race/ethnicity, nativity, and several types of homicide motives. Results. Contrary to popular expectations, ethnicity and immigration status rarely play a role in the types of homicide involvement of victims or violators. Incident characteristics, such as multiple offenders, or gender and age, were consistently more important influences in shaping homicide circumstances. Conclusions. The analyses revealed few significant relationships between immigration status and homicide motives, suggesting that immigrant groups like the Marielitos have more in common with native groups' experiences of criminal violence than is commonly assumed.     

Anger and Approach Motivation in Infancy: Relations to Early Childhood Inhibitory Control and Behavior Problems

The relations among infant anger reactivity, approach behavior, and frontal electroencephalogram (EEG) asymmetry, and their relations to inhibitory control and behavior problems in early childhood were examined within the context of a longitudinal study of temperament. Two hundred nine infants’ anger expressions to arm restraint were observed at 4 months of age. Infants’ approach behaviors during play with an unpredictable toy and baseline frontal EEG asymmetry were assessed at 9 months of age. Inhibitory control during a Go/No‐Go task and parent report of behavior problems were evaluated at 4 years of age. High anger‐prone infants with left, but not right, frontal EEG asymmetry showed significantly more approach behaviors and less inhibitory control relative to less anger‐prone infants. Although a link between anger proneness in infancy and behavior problems in early childhood was not found, a combination of low approach behaviors and poor inhibitory control was predictive of internalizing behaviors.     

The Role of Maternal Behavior in the Relation between Shyness and Social Reticence in Early Childhood and Social Withdrawal in Middle Childhood

The moderating effect of maternal behavior in the relations between social reticence and shyness in preschool and subsequent social withdrawal was investigated. Eighty children (47 females) were judged for degree of social reticence during play with unfamiliar peers at the age of four and mothers completed the Colorado child temperament inventory (CCTI). At the age of seven, the children were coded for degree of social withdrawal during peer play and mothers and children were observed during structured and unstructured activities. Two significant interaction effects indicated that maternal report of shyness was a positive predictor of age‐seven social withdrawal when mothers lacked positivity; whereas observed social reticence was associated with higher degrees of social withdrawal when mothers were highly negative. Maternal positivity and negativity differentially influenced the development of social withdrawal in childhood, such that maternal negativity is associated with poor social functioning in children who have an established history of social withdrawal; whereas maternal positivity is associated with better social outcome for preschoolers who are viewed as temperamentally shy.     

Nonverbal Reactions to Conversational Interruption: A Test of Complementarity Theory and the Status/Gender Parallel

The present research examined nonverbal reactions to conversational interruption (a status-organizing cue). We predicted that the nonverbal reactions to interruption (versus a control condition) would show a different pattern of results than gender differences. Participants (N = 150) were paired with one of four confederates and randomly assigned to either an interruption or control condition. Nine nonverbal behavioral reactions were coded by independent raters. Participants responded to interruption with reciprocal interruptions and increased nodding, as compared to a control condition. Gender differences diverged from those associated with condition. Women smiled, agreed, nodded, and laughed more than men, showing evidence of a greater attempt to facilitate the flow of conversation. We discuss these findings with regard to the dimensions of affiliation and verticality.     

“I’ve Always Wanted a Gay Family Member!”: Straight Ally Girls and Gender Inequality in a High School Gay-Straight Alliance

Research on high school Gay-Straight Alliances (GSAs) focuses on these clubs as safe spaces for students of all sexual and gender orientations to gather, arguing that GSAs are usually associated with less hostile school climates. Less studied are the interactions among students in GSAs and the ways gender and sexuality intersect in this context. This ethnographic study bridges this gap, examining inequality along lines of gender and sexual identity. Findings show that straight girls are given a voice in the GSA, applauded for their support, and immune from critique of their ally work, however, some lesbian, bisexual, and queer-identifying (LBQ) girls are disenchanted with straight girls’ participation. Some LBQ girls remain silent critics of their high school’s GSA, or abandon it completely. This research suggests that within GSAs, the unconditional inclusion of straight allies may be reproducing the very inequalities such groups exist to dismantle.
